A kind of liquid-solid-liquid Three-phase decanter centrifugeTechnical field
The present invention relates to a kind of horizontal screw centrifuge, particularly a kind of liquid-solid-liquid Three-phase decanter centrifuge.
Background technology
At present, existing horizontal screw centrifuge is mainly used in solid phase dehydration, liquid phase clarification, solid-liquid liquid three phase separation, its utilizationBe that each phase difference in specific gravity is detached to carry out, but, the horizontal screw centrifuge of this structure run into solid phase proportion two liquid phases itBetween medium when, its separating effect is poor, causes the centrifuge cannot normal work.
The utility model that entitled " a kind of modified parallel flow type horizontal screw centrifuge " is disclosed in CN205032289U is specialProfit, it includes support, casing, rotary drum, auger conveyor, feed pipe, left and right bearing block, differential mechanism and drive disk assembly, and it is turningThe rotary drum flange of drum post cone intersection is provided with several apertures, and on casing correspondence position collection port is provided with.Heavy phase liquid layer can be fromFlow out at aperture, after heavy-phase liquid is discharged, sediment layer just contact the larger frictional force of generation with drum inner wall and from rotary drum small endWhat scum hole was discharged, collection port of the heavy-phase liquid containing a small amount of solid slag from casing is discharged.The horizontal screw centrifuge of this structure is notLiquid-solid two-phase laminated flow is only capable of achieving, liquid-solid-liquid three phase separation is also capable of achieving, but, due to the restriction of structure, running into solid phaseDuring medium of the proportion between two liquid phases, its separating effect is poor, causes the centrifuge cannot normal work.
The content of the invention
It is an object of the invention to provide one kind effectively can carry out detached liquid-solid-liquid three-phase to light liquid, solid phase and heavy-fluidHorizontal screw centrifuge.
The purpose of the present invention realizes that a kind of liquid-solid-liquid Three-phase decanter centrifuge is wrapped by such technical schemeRotary drum is included, in the rotary drum spiral cylinder is provided with, the small end being connected with rotary drum is respectively arranged with the two ends of the rotary drumAxle journal and big end-journal, are respectively arranged with from the inside to the outside layer of light liquid, solid layer and heavy-fluid layer in the rotary drum, the rotary drum withIts inwall of big end-journal connection end is outwardly open small-angle；Layer of light liquid is respectively arranged with the big end-journal and is discharged and led toRoad and heavy-fluid layer passing away, at the layer of light liquid passing away and heavy-fluid layer passing away liquid phase boundaries machine is respectively arranged withStructure A and liquid phase boundaries mechanism B.
Wherein, the light liquid passing away be extend transversely through be arranged on big end-journal and with layer of light liquid for discharge opeingHole.
Further describe, the outage is four, and in rectangular layout.
For the ease of changing the boundary of overall liquid phase and solid phase, the boundary mechanism A is to be arranged on big end-journal outer faceGo up and it is connected with big end-journal, for adjusting the overflow baffle of outage size.
Wherein, the heavy-fluid passing away includes the inlet opening being arranged on big end-journal inner face, in the big end axleThe screwed hole connected with inlet opening is vertically arranged with neck；It is provided with what is be connected with big end-journal inner face at the inlet openingFor blocking the baffle plate of solid layer, there is spacing, the spacing and heavy-fluid between the upper surface and inlet opening top of the baffle plateLayer correspondence.
For the ease of changing the boundary of overall solid phase and heavy-fluid, the liquid phase boundaries mechanism B is to be arranged in screwed holeCored screw.
As a result of above-mentioned technical proposal, the present invention has smart structural design, service-strong advantage, using its energyEnough improve light liquid, the separating effect between solid phase and heavy-fluid, it is ensured that the stability of centrifuge work.
Description of the drawings
The description of the drawings of the present invention is as follows：
Fig. 1 is the structural representation of the present invention；
Fig. 2 is partial enlarged drawing in Fig. 1.
Specific embodiment
The specific embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings, but the present invention does not limit toIn these embodiments, any improvement or replacement on the present embodiment essence spirit still falls within the claims in the present invention and wantsSeek the scope of protection.
Embodiment 1：As shown in Figure 1, 2, a kind of liquid-solid-liquid Three-phase decanter centrifuge, including rotary drum 1, in the rotary drum 1Spiral cylinder 2 is inside provided with, the little end-journal 3 and big end-journal being connected with rotary drum 1 is respectively arranged with the two ends of the rotary drum 14, layer of light liquid 5, solid layer 6 and heavy-fluid layer 7, the rotary drum 1 and big end-journal are respectively arranged with from the inside to the outside in the rotary drum 1Its inwall of 4 connection ends is outwardly open small-angle；Layer of light liquid passing away and weight are respectively arranged with the big end-journal 4Liquid layer passing away, be respectively arranged with the layer of light liquid passing away and heavy-fluid layer passing away liquid phase boundaries mechanism A andLiquid phase boundaries mechanism B.
Wherein, the light liquid passing away be extend transversely through be arranged on big end-journal 4 and with layer of light liquid 5 for discharge opeingHole 8.
Further describe, the outage 8 is four, and in rectangular layout.
For the ease of adjusting the boundary of solid phase and liquid phase, the boundary mechanism A to be arranged on the outer face of big end-journal 4 andIt is connected with big end-journal 4, for adjusting the overflow baffle 9 of the size of outage 8.
Wherein, the heavy-fluid passing away includes the inlet opening 10 being arranged on the inner face of big end-journal 4, at the big endThe screwed hole 11 connected with inlet opening 10 is vertically arranged with axle journal 4；Be provided with the inlet opening 10 with big end-journal 4The baffle plate 12 for blocking solid layer 6 of end face connection, has spacing, institute between the upper surface of the baffle plate 12 and inlet opening 10State spacing corresponding with heavy-fluid layer 7.
For the ease of changing the boundary of overall solid phase and heavy-fluid, the liquid phase boundaries mechanism B is to be arranged in screwed hole 11Cored screw 13.
In the present invention, overflow baffle 9 is arranged on big end-journal 4 by screw, and by overflow baffle 9 outage is adjustedThe size of 8 perforate, effectively can change out the line of demarcation of overall liquid phase and solid phase, and then improve the solid content of liquid and go outThe moisture percentage of slag；Adjustable cored screw 13 is arranged on inside the screwed hole 11 of big end-journal 4, can be with long inner hexagon spanner pairCored screw 13 gos deep into the radial distance of big end-journal 4 and is adjusted, and can control the interface between two liquid phases, Jin ErgaiKind heavy-fluid containing solid and rate containing clear liquid, and in order to ensure the liquid layer depth of heavy-fluid, in big end-journal 4 with mode connects for screw one gearPlate 12, it can be prevented effectively from proportion in middle solid by heavy-fluid channel blockage, and can form a heavy-fluid pond higher,And the heavy-fluid of straight-section rotary drum can be made to be quickly returning to heavy-fluid pond by the small-angle of rotary drum, and then ensure that spiral pushes away the smooth of solidProperty.
