Specific embodiment
In order to deepen the understanding of the present invention, the present invention is described in further detail below in conjunction with embodiment and attached drawing,
The embodiment is only used for explaining the present invention, does not restrict the protection scope of the present invention.
As shown in Figures 1 to 6, slurry delivery pump, including speed reducer 1, shaft coupling 2 and the pump housing 3, speed reducer 1 passes through shaft coupling
Device 2 is connect with the pump housing 3, and the pump housing includes pump case 31, and 31 top of pump case is equipped with discharge port 32, and 31 top side of pump case is equipped with feed inlet
33, lower part installation camber waist wheel 34 in pump case 31,34 top of camber waist wheel is set there are one small runner 35, and being combined on small runner 35 has
Two side plates 39 being arranged in parallel, one end combination of side plate 39 have pressing plate 36, and the other end is equipped with to be led to for what rotary shaft 4 passed through
Hole, rotary shaft 4 are mounted on pump case 31, and the both ends of rotary shaft 4 are additionally provided with pressure and rotate back to compound spring 38.It is set on pump case side wall
There is link stopper 5, one end and the pressing plate 36 of link stopper 5 are engaged, and the other end is contacted by spring 6 with pump case side wall.Link stopper material is
Wear-resistant copper alloy, adjustable spring are stainless steel.When camber waist wheel rotates, pressing plate 36 is jacked up, and pressure rotates back to compound spring 38
Rotary shaft is promoted to rotate to original position there are a twisting resistance enables pressing plate rapid decrease, is close to the pump case side of 32 lower section of discharge port
Backflow of slurry is prevented on the link stopper of wall, is not in that pressing plate is jacked up and too high leads to pressing plate and the discontiguous feelings of pump case side wall link stopper
Condition occurs.Bottom can be equipped with camber alloy pad tabletting in pump case, and camber waist wheel 34 is contacted with half camber alloy pad tabletting 37
Using unoxidizable alloy steel making abrasion-proof corrosion-proof, camber waist wheel feed inlet and is gone out using HT300 high-quality grey cast-iron manufactures for part
Material mouth, which is generally, side into also can root user demand otherwise designed.
Operation principle is as shown in Figure 7：Slurry delivery pump camber waist wheel under motor driving will contain a large amount of size particles
Slurry is sucked from feed inlet, and the closed bin of bottom in pump case is entered with the rotation of camber waist wheel（By camber waist wheel and pump case
The cavity that bottom is formed）, since camber waist wheel is 8 font structures, two semicircle wheels of protrusion and pump case contact surface gap are very
Small, slurry is constantly moved up in the case where the extruding of camber waist wheel pushes, while camber waist wheel rotates, the small runner in top
As camber waist wheel surface track can not stall, move up and down so as to combine the pressing plate on small runner also with small runner, by
The pressing plate on the small runner of effect for rotating back to compound spring in rotating shaft terminal pressure is close in the case where constantly conjugating up and down
Make slurry that can not flow back on pump case side wall link stopper below discharge port 32, the reflux of more effective blocking slurry and air is so as to make
A certain amount of vacuum is generated at feed inlet, and bulky grain slurry is sucked into working chamber again and is recycled with this.During the work time, it is small
Runner just as a comet on camber waist wheel constantly moved with the track that camber waist wheel rotates so that with dynamic pressure plate it is effective
The reflux of blocking slurry makes the bulky grain sent up slurry constantly be delivered up, and dehvery lift is up to 10-20 meters.
Mainly slurry high to all kinds of viscosity and containing a large amount of size particles squeeze and is cut the slurry delivery pump of the present invention
Cut conveying.The material contact portion of slurry delivery pump is formed using good grey cast-iron, and feeding camber waist wheel component uses
HT300 grey cast-irons, which form and carry out quenching treatment, plays the role of anticorrosive anti-wear, can be widely used for ore slurry, ichthyophagy crab shrimps,
The various slurries containing a large amount of particles such as shell carry out totally-enclosed pipeline.
