Peristaltic pumpTechnical field
Peristaltic pump is the utility model is related to, is exactly specifically the transmission mechanism of peristaltic pump and the improvement knot of rotor arrangementStructure.
Background technology
Peristaltic pump of the prior art is widely used in the industrial circles such as chemical industry, and its basic structure includes housing and is placed in shellInternal flexible pipe, the rotor field spider rotated by main shaft drives drive roller squeezing tube come pumped medium.In the prior art, rotorDriven by the power output shaft of speed changer, the power intake of speed changer is connected with motor shaft, and decelerator of the prior art isGear-box type decelerator, this decelerator are set in the axial end portion of rotor, and not only complete machine is big in the axial dimension of rotor, andAnd can only connect and drive a rotor, it can only be when using increase equipment or extending pumping to pump substantial amounts of medium to satisfactionBetween.
Utility model content
The purpose of this utility model is to provide a kind of peristaltic pump, while peristaltic pump is reduced in rotor axial space, hasProfit arrangement birotor, improve the pumping efficiency of medium.
To achieve the above object, the utility model employs following technical scheme：A kind of peristaltic pump, reducer shell contentReceiving has turbine and worm screw to coordinate the reducing gear formed, and worm screw is stretched out by bearing rotational support on reducer shell and one end to be subtractedFast device housing is connected with motor shaft, and the turbine wheel shaft in the middle part of turbine forms main shaft, and main shaft is by bearing rotational support in reducer shellShaft end that is upper and stretching out reducer shell is connected to rotor centre of gyration position.
By adopting the above-described technical solution, using turbine and worm reducer, can directly connect on reducer shellConnect a hose sheath to be used to house flexible pipe, save the material of equipment, and the shaft end of the turbine wheel shaft of turbine is directly and rotorIt is connected so that the size on the axial direction of the rotor of decelerator substantially reduces, further, since the disc type shape and turbine of turbineThe basic characteristics of axle, the two axial ends of turbine wheel shaft are favorably used for connection flexible pipe pump rotor, it is so small-sized in the axial directionSituation can arrange two rotors, can significantly improve equipment effectiveness in the case where adding a rotor, reduce equipmentInvestment, meets the urgent needs for pumping a large amount of media.

Embodiment
As illustrated, a kind of peristaltic pump, turbine 12 is accommodated in reducer shell 10 and worm screw 13 coordinates the deceleration formedMechanism, worm screw 13 stretch out reducer shell 10 on reducer shell 10 and one end by bearing rotational support and are connected with motor shaft,The turbine wheel shaft at the middle part of turbine 12 forms main shaft 14, and main shaft 14 is by bearing rotational support on reducer shell 10 and stretching out deceleratorThe shaft end of housing 10 is connected to the centre of gyration position of rotor 40, and rotor 40 suspends the roller 41 at end and the roll-in of flexible pipe 30 coordinates,Flexible pipe 30 is arranged in the outside tube seat of reducer shell 10.
In above-mentioned technical proposal, the axial spacing between the surface of revolution of rotor 40 and the surface of revolution of turbine 12 only has disposed axleThe spacing held, plus the spacing between fraction of rotor 40, the surface of revolution of turbine 12 and housing 10 therebetween, so in axial sideUpwards, reducer shell 10 is utilized into a part of housing of rotor 40 and flexible pipe 30, by reducer shell 10 and flexible pipe shield20 are reasonably combined so that the axial dimension of the pump housing greatly reduces, and is set relative to decelerator of the prior art and the pump housingCount into the independent sector reconnection installation of two and not only save material and man-hour, the connection being omitted between decelerator and rotorThe setting of axle device.
In order to coordinate the own characteristic of turbine and worm mechanism and be easy to arrange and install rotor 40 and flexible pipe 30, such as Fig. 2,3Shown, reducer shell 10 encloses flat casing shape relatively by the basin mouth of halfbody 11 of two peviforms.
Flexible pipe shield 20, flexible pipe shield 20 and reducer shell are provided with the outside of the both ends of the surface of described reducer shell 10Annular groove 21 is enclosed on the outside of 10 both ends of the surface and forms tube seat, and flexible pipe 30 is placed in annular groove 21, and the pipe end of flexible pipe 30 is certainlyDrawn at the bottom land of annular groove 21, main shaft 14 is extended in the vallecular cavity of flexible pipe shield 20 and is connected with rotor 40.
In such scheme, it is utilized in the both ends panel body of reducer shell 10, the main shaft 14 of turbine 12 extends to softIt is connected in the vallecular cavity of pipe protective cover 20 and with rotor 40, rotor 40 works, and for main shaft 14, stress is to be arranged symmetrically, soBy the steady engagement of more favourable turbine and worm, extend its service life.
Due to make use of reducer shell 10, this processing and installation for allowing for flexible pipe shield 20 also becomes very convenient,I.e. described flexible pipe shield 20 includes the coaming plate for forming bottom land, and built-in, external annular is respectively arranged with its interior outer side edgesFlange 22,23, built-in annular flange 22 are connected with halfbody 11, as illustrated, at the described upper annular plate face 111 of halfbody 11 justThere is provided to be connected with each other with annular flange 22.
