Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of solid-liquid separation equipment, specifically referring to a solid-liquid separation tank for chemical raw materials. Background Technology
[0002] Solid-liquid separation is a crucial step in chemical production processes and is widely used in many processes such as raw material purification and product refining.
[0003] Because chemical raw materials are complex in composition, they often contain viscous substances, fibrous impurities, and particles of varying sizes. During solid-liquid separation, these substances are very easy to adhere to and accumulate on the filter screen, causing the filter screen pores to become smaller or even completely blocked. Once the filter screen is blocked, the separation efficiency will drop sharply, the liquid flow rate will slow down, the production cycle will be forced to be extended, seriously affecting the production progress, and the cleaning is extremely difficult. Utility Model Content
[0004] The technical problem this invention aims to solve is that the filter screen of existing separators is prone to clogging after prolonged use and is difficult to clean.
[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a chemical raw material solid-liquid separation tank, including a tank body, a material discharge port is provided at the bottom of the tank body, and a liquid discharge pipe is provided on the bottom side wall of the tank body;
[0006] It also includes a separating filter screen and a hydraulic cylinder. The separating filter screen is cylindrical and vertically connected to the top and bottom walls of the tank. The discharge port is located below the separating filter screen. The hydraulic cylinder is installed on the top of the tank. The output end of the hydraulic cylinder is equipped with a pressure plate. A rotating ring is rotatable on the top of the pressure plate. A cleaning brush is provided on the outer side wall of the rotating ring. A rotating component is connected to the rotating ring. Multiple sets of support rods are equidistantly arranged at the bottom of the tank. A sealing plate for blocking the discharge port is movably arranged between the multiple sets of support rods. A propulsion component is connected to the bottom of the sealing plate.
[0007] Furthermore, the rotating assembly includes a gear ring and an electric motor. The gear ring is fixed on the inner sidewall of the rotating ring, and the electric motor is mounted on the top wall of the push plate. The output end of the electric motor is provided with a gear that meshes with the gear ring.
[0008] Furthermore, the propulsion assembly includes a base plate and an electric push rod. The base plate is disposed at the bottom of the multiple sets of support rods, and the electric push rod is disposed on the base plate. The output end of the electric push rod is connected to the bottom of the sealing plate.
[0009] Furthermore, a slider that slides on the support rod is fixedly connected to the side wall of the sealing plate.
[0010] Furthermore, a feed pipe is provided through the top wall of the tank, and the bottom of the feed pipe is inserted obliquely into the side wall of the separation filter.
[0011] Preferably, an annular water supply pipe is installed on the top side wall of the tank, and a spray pipe with evenly distributed nozzles is branched on the bottom wall of the water supply pipe. A liquid addition pipe penetrating the side wall of the tank is provided on the side wall of the water supply pipe.
[0012] The beneficial effects achieved by adopting the above-described structure are as follows:
[0013] 1. By setting up a cylindrical separation filter screen and sealing the material inlet with a sealing plate, the raw materials inside the separation filter screen can be squeezed and separated. At the same time, after the pressure plate moves, the gear driven by the electric motor drives the gear ring to drive the rotating ring to rotate. The rotating ring drives the cleaning brush to move, which facilitates the cleaning of the separation filter screen and avoids clogging of the separation filter screen.
[0014] 2. By installing water supply pipes and spray pipes, the separation filter screen can be further cleaned by rinsing with clean water after solid-liquid separation, thereby improving the cleaning effect of the separation filter screen. Attached Figure Description

[0022] like Figure 1-4 As shown, this utility model proposes a chemical raw material solid-liquid separation tank, including a tank body 1, a feed pipe 19 penetrating the top wall of the tank body 1, a discharge port 2 at the bottom of the tank body 1, and a drain pipe 3 on the bottom side wall of the tank body 1; it also includes a separation filter screen 4 and a hydraulic cylinder 5. The separation filter screen 4 is cylindrical and vertically connected to the top and bottom walls of the tank body 1, making the tank body 1 divided into inner and outer sides. The bottom of the feed pipe 19 is inclined and inserted into the side wall of the separation filter screen 4. The discharge port 2 is located below the separation filter screen 4. The hydraulic cylinder 5 is installed... Installed on the top of tank body 1, hydraulic cylinder 5 has a pressure plate 6 at its output end. A rotating ring 7 rotates on the top of the pressure plate 6. A cleaning brush 8 is provided on the outer side wall of the rotating ring 7. A rotating component 9 is connected to the rotating ring 7. Four sets of support rods 10 are equidistantly arranged at the bottom of tank body 1. A sealing plate 11 for blocking the material discharge port 2 is movably arranged between the four sets of support rods 10. A slider 18 that slides on the support rods 10 is fixed to the side wall of the sealing plate 11 to ensure the stability of the sealing plate 11. A propulsion component 12 is connected to the bottom of the sealing plate 11.
[0023] Start the propulsion assembly 12, seal the discharge port 2 with the sealing plate 11, pour the raw material into the tank 1 from the feed pipe 19, and let it flow into the cylindrical separation filter screen 4. Start the hydraulic cylinder 5, drive the pressure plate 6 to press down, squeeze the raw material, and separate the solid and liquid. At the same time, the rotating assembly 9 drives the rotating ring 7 to rotate, which in turn drives the cleaning brush 8 to rotate, clean the inner wall of the separation filter screen 4, and prevent the separation filter screen 4 from clogging. The separated liquid is discharged through the drain pipe 3. After solid-liquid separation, lower the sealing plate 11 and push the solid out from the discharge port 2 to complete the separation.
[0024] like Figure 3 and4 As shown, the rotating assembly 9 includes a gear ring 13 and an electric motor 14. The gear ring 13 is fixed on the inner side wall of the rotating ring 7, and the electric motor 14 is mounted on the top wall of the push plate. The output end of the electric motor 14 is provided with a gear 15 that meshes with the gear ring 13. When the electric motor 14 is started, the gear 15 is driven to rotate, the gear 15 drives the gear ring 13 to rotate, and the gear ring 13 drives the rotating ring 7 to rotate, thereby driving the rotating ring 7 and the cleaning brush 8.
[0025] like Figure 3 As shown, the propulsion assembly 12 includes a base plate 16 and an electric push rod 17. The base plate 16 is located at the bottom of the four sets of support rods 10, and the electric push rod 17 is located on the base plate 16. The output end of the electric push rod 17 is connected to the bottom of the sealing plate 11. When the electric push rod 17 is activated, it pushes the sealing plate 11 upward to facilitate sealing the material discharge port 2.
[0026] A ring-shaped water supply pipe 20 is installed on the top side wall of the tank 1. A spray pipe 21 with evenly distributed nozzles branches off the bottom wall of the water supply pipe 20. A liquid addition pipe 22 is provided on the side wall of the water supply pipe 20, penetrating the side wall of the tank 1. After solid-liquid separation, the liquid addition pipe 22 is connected to a high-pressure water source, and the water is sent into the spray pipe 21 through the water supply pipe 20. Finally, the water is sprayed out through the nozzles on the spray pipe 21 to clean the separation filter 4, further avoiding the possibility of clogging of the separation filter 4.
