' saw u BF 4 FIG-8 55 82 60 63 83 BLENDER WITH INTEGRAL INTENSIFIER BACKGROUND OF THE INVENTION This invention relates tobIenders for combining or agitating various ingredients, either liquid or solid, and more particularly to a blender system for use with a separate power drive means. This invention discloses a blending system wherein the blending vessel, once closed, may be removed from the drive means at will, transported and/or stored as desired, and so on, without the need to open the' vessel for partial disassembly of the blending system before removal from or attachment to the power drive means. I Blending systems using rotatable vessels of various configurations, to contain and mix, blend, or agitate the contents thereof, are well known in the art. Such vessels have many different configurations and are operated at a wide variety of speeds, according to the desired result.

It is also known in the art to equip such vessels with internal agitators or intensifiers which may be operated independently of the vessel'itself. Frequently the intensifier is rotated at a speed much greater than that of the vessel, resulting in partial pulverization of the contents, in addition to the blending thereof. US. Pat. Nos. 2,890.027 and 3,174,728 provide examples of such blending systems, and further suggest the use of the intensifier to introduce fluids into the contained materials during the blending process. These references also disclose several means for removing the contents of the vessels after blending. g

Until now, however, it has generally been necessary to remove the finished ingredients from the vessel before they could be transported. This has been especially true where an internal intensifier has been employed, since the entire system is constructed as integral unit, including the power drive sou'rces. Thus, in a blending system using internal intensifiers, the entire blending system requires expensive and time consuming disassembly in order to transport the finished ingredients within the blender itself. Frequently, the intensifier must first be separately removed, a highly burdonsome requirement when the vessel is already nearly full of ingredients.

As a result, blending systems having internal intensifiers are rarely portable. Whenever the ingredients are to be transported, stored, re-agitated, and so on, they must be transferred and re-transferred again and again to other containers. This i s-not only expensive and time consuming, but there is always the risk of product and- /or environmental contamination when the products and environment are brought into contact. Furthermore, to clean the blending system, the cleaning means must come to the vessel, notvice versa, another source of inconvenience.

SUMMARY OF THE INVENTION It is therefore an object of this invention to provide a blending system for the blending or agitation of ingredients wherein a closeable blending vessel and an internal intensifier are jointly removable and transportable, as a unit, from the power drive means; a blending system wherein the intensifier within the vessel may be rotated independently of the vessel; a convenient mounting means for mounting the intensifier rotatably and removably within the vessel; a convenient coupling 2 a means for quickly and easily coupling the vessel and the intensifier to a separate power drive means for independent powered rotation of the vessel and/or the intensifier; a blending system wherein liquid may be introduced through the intensifier into the ingredients within the closed vessel; and to accomplish all of the above objects and purposes in both a method and apparatus which are functional, inexpensive, reliable, durable, and highly convenient in construction and operation.

Briefly, one embodiment of this invention includes a closeable blending vessel having an intensifier rotatably mounted therewithin.

The blending vessel carries a mounting unit which rotatably mounts and supports the intensifier within-the vessel, and connects through the side of the vessel for rapid attachment to or removal from a power drive unit. The mounting means also connects rigidly to the vessel itself, for separate support and rotation of the vessel as well.

The mounting means on the vessel has a collar on the outside thereof which can be grasped by the power drive means for rotating the vessel. A slotted central shaft in the mounting means is engageable by a slotted central drive shaft on the power drive means for separately rotating the intensifier within the vessel.

The power drive means has a jaw type compression coupling into which the collar of the vessel mounting means is inserted. A single bolt clamp compressibly engaged about the coupling tightens the jaws thereof to grasp and hold the collar.

The intensifier has hollow conduit channels therewithin, and a liquid supply tube may be inserted through the hollow central power drive shaft into the hollow vessel central shaft and into the intensifier, to introduce liquid therethrough during the blending operation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to the drawings, and more particularly to FIG. 1, there is illustrated ablending system 10 according to this invention.Blending system 10 includes a blending vessel 11, such as the conical vessel 12 of FIG. 1, theribbon vessel 13 of FIG. 5, or the V shaped vessel 14 of FIG. 6. Any other appropriate shape may of course be utilized.

The blending vessel 11 has an intensifier 15 mounted therein. The intensifier, similarly, may have any desired configuration, such as the partial helix intensifier configuration 16 (FIGS. 3 and 5) or the disperser intensifier configuration 17 (FIGS. 4 and 6).

A mounting means 20 is carried by blending vessel 1 1 and is attached rigidly thereto. Mounting means 20 supports vessel 11 during the blending process, and is provided with acollar 21 which may be gripped to support and rotate blending vessel 11. Mounting means 20 also includes acentral shaft 23 to which intensifier 15 may be attached by any suitable means, such asscrews 24. The external end ofcentral shaft 23 is provided with aslot 25 by whichcentral shaft 23 may be engaged and rotated.Central shaft 23 is rotatably mounted within mounting means 20 by means of ball bearing 28.Suitable seals 29 are provided along the internal end of mounting means 20 to allow for relative rotation between mounting means 20 andcentral shaft 23 while preventing the ingredients within vessel 11 from escap- A power drive means 30 includes amotor 31 for driving intensifier 15, and amotor 32 for driving vessel 11. These motors are suitably connected to a power drive meanscoupling 35.Coupling 35 is provided with an outerconcentric drive shaft 36 driven bymotor 32, and an innerconcentric drive shaft 37 driven bymotor 31.Motors 31 and 32 are separately controllable by a control means (not shown) to allow either motor to be operated or not operated, as desired, and at any speed appropriate to the task.

Ball bearing 38 and roller bearing 39 (FIG. 4) within power drive meanscoupling 35 supportinner drive shaft 37 for rotation withinouter drive shaft 36.

Outerconcentric drive shaft 36 oncoupling 35 also includes a jawtype compressing coupling 40 of a size suitable to receivemountingmeans collar 21 therein.Jaw coupling 40 is actuated by means ofsingle bolt clamp 42 disposed thereabout, to close around andgrip collar 21. By this means theentire blending system 10 may be attached to and supported by the power drive means 30.

Concentric drive shaft 37 is provided withslots 43 which mate with and engageslots 25 in central mounting meansshaft 23. By this meansdrive shaft 37 is able to drive intensifier 15.

A liquid supply tube 45 (FIGS. 4 and 6) conducts liquid into the center ofintensifier 15 for dispersion therefrom into the contents of vessel 11 during blending or mixing therein. The liquid is conducted within intensifier 15 throughconduits 46 therein. Innerconcentric drive shaft 37 andcentral shaft 23 are hollow in the centers thereof for reception ofliquid supply tube 45 thcrcthrough.Liquid supply tube 45 is provided with a seal 47 in order to prevent liquid or other material from escaping through the hollow centers ofshafts 23 and 37.Liquid supply tube 45 also has an external seal 48 (FIG. 4) which also prevents rotation ofsupply tube 45.

FIG. 5 illustrates an alternate arrangement wherein vessel 11 is not rotated. Instead, only intensifier 15 is rotated. A stabilizingbar 50 connects vessel 11 to the frame of power drive means 30 to prevent rotation of the vessel. In this case, mountingmeans 20 includes only a single shaft, which is fitted to be received and supported bycompression coupling 40, similarly as discussed above.Wing nuts 51 provide for quick attachment and removal ofstabilizingbar 50. Asupport strut 52 aids in supporting vessel 11.

FIGS. 7 and 8 illustrate another embodiment of the blending system of this invention similar to that of FIG. 5. However, in FIG. 7 the vessel 11 is an open-top U shapedvessel 55 having a removable top 56.Vessel 55 is stationary and is supported both by jawtype compression coupling 40 and asupport strut 57.

A speed reducer is mounted between the power drive means 30 and thevessel 55. Thespeed reducer 60 has anoutput shaft 61 which is connected to anintensifier 62 rotatably supported within thevessel 55 by means ofbearings 63. Theintensifier 62 is formed withdouble helix blades 64 mounted on ahollow drive shaft 65 by means ofarms 66. Theblades 64, by virtue of being driven byspeed reducer 60, are able to exert great force against the material within thevessel 55.

Theintensifier 62 is removably mounted within thevessel 55. Thehollow shaft 65 includesshaft having threads 71 and 72 formed on either end thereof. The threads 71 are threaded in reverse direction from thethreads 72.Retractable coupling members 75 and 76 are slidably mounted in each end of theshaft 65 and are threaded internally to receive thethreads 71 and 72, respectively. Thecoupling members 75 and 76 each include aslot 77 which cooperate withscrews 78 to prevent their rotation relative to theshaft 65 while permitting longitudinal movement thereof.

The output of thespeed reducer 60, as shown in FIG. 8, is carried by adrive shaft 61. Surrounding this shaft is aseal plate 81 which is secured to the shaft by means of aset screw 24. Between theplate 81 and the wall of thehousing 55 is arubber seal member 82 and a feltseal member 83. Theplate 81 is adjusted on theshaft 61 to compress the rubber and felt members slightly with the result that the rubber and felt members do not rotate relative tovessel 55 and therefore all relative rotation occurs between the feltmember 83 and theplate 81.

Theseal plate 81 includes a plurality ofslots 85 for receivingpins 86 which extend outwardly from theretractable coupling member 75. Similar construction may be found at the right of the device as shown in FIG. 8 where thecoupling member 76 may be supported for rotation on ashaft 88. This shaft is also rotatably supported within the vessel by abearing 63. Bothshafts 61 and 88 have frustoconical end portions which may be received into corresponding reliefs in theretractable coupling members 75 and 76 in order to align thehollow shaft 65 with the axis of rotation.

The threadedshaft 70 may be rotated relative toshaft 65 by an external device including ashaft 90 having a tip 91 which is received into a slot 92 in theshaft 70. Theshaft 90 is held in a retracted position by means of aspring 93. Aknob 94 serves as an external locking control and is mounted at the end ofshaft 90 to allow the operator to insert the shaft, against the bias of thespring 93, into locking engagement with threadedshaft 70. The knob may then be rotated to rotateshaft 70 and to cause theretractable coupling members 75 and 76 to move toward or away from theplates 81, thereby to engage or release the intensifier from its driving connection with the source of rotational power. By this means, the intensifier may be quickly and easily inserted and locked into, or unlocked and removed from thevessel 55. In FIG. 7, the intensifier is shown in locked position, while in FIG. 8 it is shown with the retractable coupling members retracted in preparation for removal. I

Eachvessel 55 is provided with anappropriate port 95 which permits the operator to insert or remove ingredients from the vessel Without removing thecover plate 56.

This invention therefore'supplies an integral blending system in which the intensifier is supported within the blending vessel on a suitable shaft, bearings, and seals which remain with the blending vessel after the removal thereof from the support coupling and drive assembly. The invention therefore makes possible the use of an unlimited variety of intensifier configurations and of vessel sizes and shapes, each being appropriate to the particular task, and each being operable independently at speeds appropriate to the joint task. As indicated, either the intensifier or the vessel may also be nonrotated.

With this invention each vessel may be charged with ingredients at any convenient location, and at any time. A large number of vessels may be employed without the need for a large number of power drive means. Various operations may be performed upon the vessels at various times without the need to open them or to drain the contents to free the power drive means for performing other tasks. The contents may thus be sealed within each vessel for any length of time, protecting the contents from environmental contamination, and protecting the environment from contamination from the contents. Similarly, with the use of interchangeable shells, cross contamination from different charges can be entirely eliminated. At the same time,the desired combination of intensifier and vessel may be used, appropriate to the particular task, without requiring extensive assembly or disassembly of the complete system. Once the vessel and the intensifier are selected and assembled and the appropriate charge placed therein, they may be very quickly'and conveniently attached to and removed from the power drive means, and a minimum of time and effort is involved in changing from one to another.

While the method and forms of apparatus herein described constitute preferred embodiments of the invention, it is to be understood that the'invention is not limited to the precise method and forms of apparatus, and that changes may be made therein without departing from the scope of the invention.
