Description

Vane pump shaft sealer and soy bean milk making machine thereof

Technical field

The soy bean milk making machine that the utility model relates to the vane pump shaft sealer and uses this sealing device.

Background technology

The shaft sealer of traditional blades pump generally all uses outside framework oil seal to carry out the sealing of motor, circulation cavity end face and impeller bottom surface all are the planes, because assembling needs, between circulation cavity and impeller, can leave the gap, liquid can be easy to penetrate between motor shaft and the circulation cavity from this gap, penetrate into the outside framework oil seal place along motor shaft then, when in the liquid slag being arranged, slag concentrates at the lip place of outside framework oil seal, time is not long promptly dry and hard, under the effect of running up of electric machine main shaft, slagging scorification place temperature rises rapidly, the outside framework oil seal lip will soon be worn and lose efficacy, and screenings bleeds along electric machine main shaft in the motor, generally uses hundreds of time rear motor promptly to be damaged.Another can be used for doing the colloid mill of soya-bean milk on the market, what generally use is mechanically-sealing apparatus, this device installation requirement and cost are all than higher, and when grinding soybean, spring place in the mechanically-sealing apparatus is slagging scorification easily also, cause spring failure, make dynamic and static ring rubbing surface contact imprecision, and occur leaking.

Summary of the invention

The utility model overcomes the shortcoming of prior art, provides that a kind of sealing property is good, the vane pump shaft sealer of long service life and use the soy bean milk making machine of this sealing device.

The purpose of this utility model is achieved by following technical proposals: a kind of vane pump shaft sealer, along main shaft impeller, circulation cavity, outside framework oil seal are installed successively from top to bottom, impeller is positioned at circulation cavity inboard, outside framework oil seal is positioned at the external side resettlement groove of torus, it is characterized in that the impeller lower end is provided with shoulder hole and forms ring cavity with main shaft, the circulation cavity extends an annular boss along main shaft in ring cavity.

Between the end face of described annular boss and ring cavity V-seal spare is installed.

The soy bean milk making machine of technical solutions of the utility model, comprise pulping device, vane pump, pulping device is in the vane pump upstream, pulping device is installed hopper, moving bistrique, quiet bistrique and motor from top to bottom successively, quiet bistrique is sleeved on moving bistrique outside, quiet bistrique lower end is connected with the circulation cavity of vane pump, impeller is fixed on the moving bistrique lower surface, moving bistrique is fixed on the motor reel, the circulation cavity is installed on the motor upper end cover, it is characterized in that described vane pump has described vane pump shaft sealer.

Described soy bean milk making machine also is provided with control valve assembly, circulation line, and the vane pump outlet links to each other with the entrance point of control valve assembly, and an end of circulation line links to each other with an outlet of control valve assembly, and its other end leads to hopper.

The utility model compared with prior art, the advantage that has is: extend an annular boss at circulation cavity end face along main shaft, can reduce to penetrate into the screenings quantity and the pressure at motor shaft place greatly, even a small amount of infiltration is arranged, also can assemble in the ring cavity above annular boss, form a new seal isolation ring.Outstanding muscle in the wheel bottom setting; the V-seal spare of laying in the ring cavity the inside, and the blocking material ring of outside framework oil seal top all play the effect that reduces screenings leakage quantity and pressure; being equivalent to has increased multiple protective in the outside framework oil seal front, thereby improves greatly the life-span of shaft sealer.Another one advantage of the present utility model provides a kind of retaining ring; cover motor shaft extension hole; and rotate together along motor main shaft; the screenings that leaks out from outside framework oil seal can be thrown away motor shaft extension hole; and with the guiding gutter outflow that is provided with on the motor upper end cover; can not drain to the motor the inside even there is screenings to leak so yet, reach the purpose of protection motor.Simultaneously, this structure is in processing and install all very simply, is convenient to realize.

The specific embodiment

Below in conjunction with drawings and Examples concrete structure of the present utility model is described further.

A kind of vane pump shaft sealer of the utility model embodiment as shown in Figure 2, along main shaft 6 impeller 4, circulation cavity 5, outside framework oil seal 13 are installed successively from top to bottom, impeller 4 is positioned at circulation cavity 5 inboards, outside framework oil seal 13 is positioned at circulation cavity 5 outside resettlement grooves, be that impeller 4 lower ends are provided with shoulder hole and form ring cavity 11 with main shaft 6, circulation cavity 5 extends an annular boss 8 along main shaft 6 in ring cavity 11; Between the end face of described annular boss 8 and ring cavity 11 V-seal spare 10 is installed; Between described circulation cavity 5 and the outside framework oil seal 13 blocking material ring 12 is housed; Described impeller 4 bottoms are provided with outstanding muscle 16.

The utility model soy bean milk making machine, embodiment as shown in Figure 1, comprise moving bistrique 3, quiet bistrique 2, main shaft 6, motor 7, hopper 1, motor 7 drives main shaft 6 rotations, moving bistrique 3 is installed on main shaft 6 axle heads, impeller 4, circulation cavity 5 are provided with annular boss 8, impeller is provided with toroidal cavity 11, in the gap between annular boss 8, toroidal cavity 11 and main shaft 6 V-seal spare 10 is housed, outside framework oil seal 13 is housed in circulation cavity 5, blocking material ring 12 is housed above the outside framework oil seal, on motor upper cover 14, is provided with guiding gutter 15.

During motor 7 runnings, driving moving bistrique 3 rotates along clockwise direction, bean or pea are squeezed in the broken gap that enters between moving bistrique 3 and the quiet bistrique 2, under roll flute impact force and the effect of intergranular friction power, pulverized and ground soya-bean milk, flow in the circulation cavity 5, under the rotary action of impeller 4, discharge the circulation cavity, behind control valve assembly 18, follow endless tube road 17 and reenter pulping device and grind from the plasma discharge mouth.In the pulping process; the part screenings infiltrates in the gap that V-seal spare 10 is installed along the gap between impeller and the circulation cavity; under the rotary action of outstanding muscle 16 of wheel bottom and V-seal spare 10; can slow down permeating speed; through after the slurrying repeatedly; the full bean dregs of gap inner product; form an isolation strip; screenings in the abrasive areas and main shaft 6 are kept apart; make screenings be difficult for leaking in the outside framework oil seal of circulation cavity 5; blocking material ring 12 above the outside framework oil seal also can stop screenings toward the interior seepage of outside framework oil seal, thereby plays the multiple protective effect.

Be with retaining ring 9 on the main shaft between circulation cavity 5 and the motor upper end cover 14, cover motor 7 shaft extension holes, and, the screenings that leaks out from outside framework oil seal 13 can be thrown away motor 7 shaft extension holes, and flow out with the guiding gutter 15 that is provided with on the motor upper end cover 14 with main shaft 6 rotations.

This device is also applicable to other abrasive blast equipments except that soy bean milk making machine.
