Description

Technical Field

[0001] The utility model relates to the technical field of air lift pumps, in particular to an air lift pump for a cyclone grit chamber. Background Art

[0002] A cyclone grit chamber is a common equipment used for solid-liquid separation. It achieves solid-liquid separation by settling the particles suspended in the water to the bottom. In the cyclone grit chamber, the water flow forms a vortex in the cyclone, causing the heavier solid particles to settle to the bottom of the chamber, while the lighter liquid is brought to the center of the cyclone, thereby achieving solid-liquid separation.

[0003] The function of the airlift pump is to improve the processing efficiency of the solid-liquid separation system by lifting solid particles to the water surface. However, in the existing cyclone sand settling tank, the gravel at the bottom of the tank is easily accumulated and compacted during separation, which is not conducive to completing the airlift work.

[0004] In order to solve the above problems, we proposed a cyclone grit chamber air lift pump. Utility Model Content

[0005] The utility model aims to solve the problems in the background technology and proposes an air lift pump for a cyclone sand settling tank.

[0007] In the above-mentioned cyclone grit chamber air lift pump, the outer side wall of the machine body is fixedly connected to a water tank, a water pump is arranged inside the water tank, and a water pipe is fixedly connected to the output end of the water tank.

[0008] In the above-mentioned cyclone grit chamber air lift pump, a drainage pipe is fixedly connected to the outer side wall of the bottom of the body, the bottom of the body is provided with a resistance-increasing texture, and a plurality of legs are fixedly connected to the outer side wall of the body.

[0009] In the above-mentioned cyclone grit chamber air lift pump, an anti-support edge is provided at the bottom of the fixed pipe, a plurality of the fixed plates are evenly arranged on the outside of the rotating column, and a plurality of the convex teeth are evenly arranged at the bottom of the pressure plate.

[0010] In the above-mentioned cyclone grit chamber air lift pump, a plurality of the legs are evenly arranged on the outer side wall of the body.

[0011] In the above-mentioned cyclone grit chamber air lift pump, the water delivery pipe is L-shaped, and the pipe end of the water delivery pipe extends to the top of the machine body.

[0012] Compared with the existing technology, the advantages of this cyclone sand settling tank air lift pump are:

[0013] The utility model uses a motor to rotate the rotating column, and the rotating column drives the fixed plate and the cyclone sheet to rotate. When the cyclone sheet rotates, a vortex is formed, so that heavier solid particles are deposited on the bottom of the pool, and lighter liquid is brought to the center of the cyclone, thereby realizing solid-liquid separation. When the fixed plate rotates, it drives the fixed pipe to rotate, and the iron block moves downward and drives the sliding rod to move downward so that the convex teeth collide with the plate hardness, and the plate hardness is broken by the collision, thereby accelerating the speed of solid-liquid separation.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3The cyclone sand settling tank air lift pump comprises a body 1, the outer wall of the body 1 is fixedly connected with a support frame 4, the bottom of the support frame 4 is fixedly connected with a motor 3, the driving end of the motor 3 is fixedly connected with a rotating column 5, the outer wall of the rotating column 5 is fixedly connected with a plurality of fixed plates 7, the outer sides of the plurality of fixed plates 7 are fixedly connected with a plurality of cyclone sheets 6, the bottoms of the plurality of fixed plates 7 are fixedly connected with a fixed tube 8, the bottoms of the plurality of fixed plates 7 are fixedly connected with a spring 9 passing through the fixed tube 8, the bottoms of the springs 9 are fixedly connected with an iron block 10, a sliding rod 11 is slidably inserted in the tubes of the plurality of fixed plates 7, a pressing plate 13 is fixedly connected to the bottom of the sliding rod 11, a plurality of convex teeth 12 are fixedly connected to the bottom of the pressing plate 13, an anti-support edge is provided at the bottom of the fixed tube 8, a plurality of fixed plates 7 are evenly arranged on the outer sides of the rotating column 5, a plurality of convex teeth 12 are evenly arranged at the bottom of the pressing plate 13, and when solid-liquid separation is required, the rotating column 5 is rotated by the motor 3. When the motor 3 stops, the spring 9 is in a stretched state, and the iron block 10 moves downward and drives the sliding rod 11 to move downward, so that the convex teeth 12 collide with the hardening, and the hardening is broken by the collision, thereby accelerating the solid-liquid separation speed and improving the processing capacity and efficiency of the system. When the motor 3 stops, the spring 9 is reset and drives the iron block 10 to reset to the initial state. At this time, the vortex in the body 1 has not dissipated, and the rotational force of the vortex causes an upward force on the pressure plate 13, and the air injected by the air lift pump also causes an upward force on the pressure plate 13, thereby moving the sliding rod 11 to the initial state.

[0020] A water tank 15 is fixedly connected to the outer wall of the machine body 1, a water pump is arranged inside the water tank 15, a water pipe 16 is fixedly connected to the output end of the water tank 15, the water pipe 16 is L-shaped, and the end of the water pipe 16 extends to the top of the machine body 1. When the inside of the machine body 1 needs to be cleaned, clean water can be added to the water tank 15 first, and then the clean water is pumped into the machine body 1 through the water pipe 16. At this time, starting the motor 3 can achieve the cleaning effect of the inside of the machine body 1.

[0021] The outer wall at the bottom of the body 1 is fixedly connected with a drainage pipe 14. When the separation is completed, the liquid in the body 1 can be discharged to the outside of the body 1 through the drainage port. The bottom of the body 1 is provided with a resistance-increasing texture 17. The resistance-increasing texture 17 can increase the collision force caused by the convex teeth 12 on the compaction, thereby causing a faster crushing effect on the compaction. The outer wall of the body 1 is fixedly connected with a plurality of legs 2, and the plurality of legs 2 are evenly arranged on the outer wall of the body 1.
