[0002] Polyaluminium chloride is an inorganic substance, an emerging water purification material, and an inorganic polymer coagulant, referred to as polyaluminium. The produced polyaluminium chloride is an inorganic polymer water treatment agent with a large relative molecular mass and a high charge. Solid-liquid separation is required during the production of polyaluminium chloride.

[0003] The existing solid-liquid separation device used in the production of polyaluminium chloride separates polyaluminium chloride into solid and liquid through a filter. Since polyaluminium chloride contains small particles, the particles will accumulate and get stuck in the mesh of the filter, affecting the effect of the solid-liquid separation of polyaluminium chloride. Utility Model Content

[0011] Preferably, the telescopic ends of the two electric push rods are jointly covered with a protective cover, and the impact ball is located inside the protective cover.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The solid-liquid separation device for the production of polyaluminium chloride is provided with an electric push rod, an impact ball and a spring. When the mixture of polyaluminium chloride and water flows to the upper surface of the filter screen through the discharge pipe, the filter screen performs solid-liquid separation on the polyaluminium chloride, and the solution flows into the sump through the filter screen. At the same time, the impact ball is driven downward by the electric push rod, and the downward moving impact ball impacts the frame, causing the frame to move downward together with the filter screen. The downward movement of the frame compresses the spring. When the electric push rod drives the impact ball to move upward, the impact ball is separated from the frame. At this time, the squeezing force of the frame on the spring disappears. The spring drives the frame to move upward during rebound, and drives the filter screen up and down through the frame, causing the filter screen to vibrate, thereby preventing the small particles contained in the polyaluminium chloride from clogging the mesh of the filter screen, thereby improving the efficiency of solid-liquid separation of polyaluminium chloride.

[0014] 2. This solid-liquid separation device for the production of polyaluminium chloride uses a water pump, a water pumping pipe and a water delivery pipe. After the solid and liquid of polyaluminium chloride are separated, the solution inside the water collection tank is transported to the upper part of the device body through the water pump, the water pumping pipe and the water delivery pipe, so that the solution can be circulated, filtered and used to avoid waste of the solution.

A spring 16 is provided on the outside of the sleeve 14 and the movable rod 15, and the impact ball 12 is driven downward by the electric push rod 11. The downward moving impact ball 12 hits the frame 9, causing the frame 9 to move downward together with the filter screen 10. The frame 9 moves downward to compress the spring 16. When the electric push rod 11 drives the impact ball 12 to move upward, the impact ball 12 is separated from the frame 9. At this time, the extrusion force of the frame 9 on the spring 16 disappears. During the rebound process of the spring 16, the frame 9 is driven upward, and the filter screen 10 is driven up and down together through the frame 9, causing the filter screen 10 to vibrate, thereby preventing smaller particles in the polyaluminium chloride from clogging the mesh of the filter screen 10 and improving the efficiency of solid-liquid separation of polyaluminium chloride.

[0024] Specifically, a motor 3 is installed at the top of the device body 1, and the shaft end of the motor 3 extends into the interior of the device body 1. The shaft end of the motor 3 is connected to a stirring rod 4, and a plurality of stirring rods 5 are connected to the outer surface of the stirring rod 4. The stirring rod 4 is driven to rotate by the motor 3, and the stirring rod 4 drives the stirring rod 5 to rotate, and the rotating stirring rod 5 stirs the solution.

[0025] Furthermore, a discharge pipe 7 is connected to the middle of the bottom end of the fixed plate 2, and an electromagnetic valve 8 is provided inside the discharge pipe 7. By opening the electromagnetic valve 8, the polyaluminium chloride solid-liquid mixture above the fixed plate 2 flows to the upper surface of the filter screen 10 through the discharge pipe 7; the top of the fixed plate 2 on both sides of the discharge pipe 7 is connected to an inclined plate 6, so that the polyaluminium chloride solid-liquid mixture above the fixed plate 2 flows to the upper surface of the filter screen 10 through the discharge pipe 7; the top of the device body 1 on one side of the motor 3 is connected to a feed pipe 21, and the raw materials and the solution are added to the inside of the device body 1 through the feed pipe 21. A sealing door 20 is provided at the front end of the device body 1. By opening the sealing door 20, it is convenient to remove the polyaluminium chloride on the upper surface of the filter screen 10. Take it out for collection; the bottom end of the inner cavity of the device body 1 below the filter 10 is connected to a water collecting tank 17, and a water pump 18 is provided at the lower part of the surface of one side of the device body 1, and the output end of the water pump 18 is connected to a water pipe 19, one end of the water pipe 19 extends to the upper part of the inner cavity of the device body 1, and the input end of the water pump 18 is connected to a suction pipe 23, one end of the suction pipe 23 extends to the inside of the water collecting tank 17. The materials of the water pipe 19 and the suction pipe 23 are both corrosion-resistant. The precipitated solution in the water collecting tank 17 is transported to the upper part of the device body 1 through the water pump 18, the suction pipe 23 and the water pipe 19, so that the liquid can circulate, and the effect of multiple filtration can be achieved, the filtration quality is improved, and the waste of precipitated solution is avoided.

[0026] Furthermore, the telescopic ends of the two electric push rods 11 are jointly covered with a protective cover 22, and the impact ball 12 is located inside the protective cover 22. The bottom structure of the protective cover 22 is elastic. During normal use, the bottom of the protective cover 22 is compressed and deformed, so that when the electric push rod 11 drives the protective cover 22 to move upward, the bottom of the protective cover 22 has elasticity, so that the protective cover 22 continues to contact the frame 9, thereby avoiding the separation of the protective cover 22 and the frame 9 during the vibration of the filter 10, and preventing the vibrating polyaluminum chloride from falling off the upper surface of the filter 10 through the protective cover 22.

[0027] The method of using this embodiment is as follows: the electrical components appearing in this application are all connected to an external power supply when in use, and are configured with corresponding controllers. First, the raw materials and the solution are added into the device body 1 through the feed pipe 21, the stirring rod 4 is driven to rotate by the motor 3, and the stirring rod 4 drives the stirring rod 5 to rotate. The rotating stirring rod 5 stirs the solution, so that polyaluminum chloride is precipitated from the solution, and then the electromagnetic valve 8 is opened to allow the polyaluminum chloride solid-liquid mixture above the fixed plate 2 to flow to the upper surface of the filter screen 10 through the discharge pipe 7, and the filter screen 10 performs solid-liquid separation on the polyaluminum chloride, and the solution flows into the water collection tank 17 through the filter screen 10, and at the same time, the impact ball 12 is driven to move downward by the electric push rod 11, and the downward moving impact ball 12 impacts the frame 9, so that the frame 9 moves downward together with the filter screen 10, and the frame 9 moves downward to compress the spring 16. When the electric push rod 11 drives the impact ball 12 to move upward, the impact The ball 12 is separated from the frame 9. At this time, the squeezing force of the frame 9 on the spring 16 disappears. The spring 16 drives the frame 9 to move upward during the rebound process, and drives the filter screen 10 to move up and down together through the frame 9, causing the filter screen 10 to vibrate, thereby preventing the smaller particles in the polyaluminum chloride from clogging the mesh of the filter screen 10, thereby improving the efficiency of solid-liquid separation of polyaluminum chloride, and transporting the solution inside the water collection tank 17 to the upper part of the device body 1 through the water pump 18, the suction pipe 23 and the water pipe 19, so that the solution can be circulated and filtered and used, avoiding waste of the solution. By opening the sealing door 20, the polyaluminum chloride on the upper surface of the filter screen 10 can be conveniently taken out for collection. Before the worker takes the polyaluminum chloride out of the inside of the device body 1, the worker needs to take protective measures to prevent the worker from being corroded by the polyaluminum chloride. The parts of the entire separation device that are in contact with the product also need to be treated with anti-corrosion, such as making the filter screen 10 out of hard rubber material.
