Description

Technical Field

[0001] This utility model relates to the field of polyaluminum chloride production equipment, and specifically to a polyaluminum chloride storage system. Background Technology

[0002] Currently, polyaluminum chloride (PAC) is classified into two types: one for drinking water and one for industrial water, each adhering to different relevant standards. It appears yellow or light yellow, dark brown, or dark gray, and exists in both liquid and solid forms. This product has strong bridging and adsorption properties, and during hydrolysis, it undergoes physicochemical processes such as coagulation, adsorption, and precipitation. The fundamental difference between PAC and traditional inorganic coagulants lies in the structure: traditional inorganic coagulants are low-molecular-weight crystalline salts, while PAC's structure consists of multi-component carboxyl complexes with varying morphologies. It exhibits rapid flocculation and sedimentation, a wide applicable pH range, no corrosiveness to pipes and equipment, and significant water purification effects. This product is widely used in drinking water, industrial water, and wastewater treatment. PAC solution is formed by mixing aluminum trichloride and calcium aluminate. Current processing methods involve directly filtering the PAC solution using a filter press to obtain a clear liquid, which is then dried to obtain powdered PAC. However, in actual production, customer needs are diverse, requiring powdered PAC, clarified PAC solution, and turbid PAC solution. Utility Model Content

[0023] As shown in the attached drawings, this utility model includes a mixing tank, a storage tank 21, and a filter press 22. A partition plate 23 is provided in the middle of the storage tank 21, which divides the inner cavity of the storage tank 21 into a turbid liquid storage area 24 and a clear liquid storage area 25. A turbid liquid extraction tank 26 and a clear liquid storage tank 27 are provided above the outlet end of the storage tank 21. The turbid liquid extraction tank 26 has an installation hole. A submersible pump 28 is provided in the turbid liquid storage area 24 below the turbid liquid extraction tank 26. The outlet pipe of the submersible pump 28 extends upward. A water pump 29 extends through the mounting hole of the turbid liquid extraction tank 26 and is installed in the clear liquid storage tank 27. The water pump 29's pumping pipe extends downward into the clear liquid storage tank 27. The discharge port of the mixing tank is connected to the feed port of the filter press 22 through the main discharge pipe 30. The filter outlet of the filter press 22 is connected to the clear liquid pipe 31. The outlet end of the clear liquid pipe 31 extends through the clear liquid storage tank 27 into the clear liquid storage area 25. A branch discharge pipe 32 is installed on the main discharge pipe 30 and is connected to the turbid liquid storage area 24.

[0024] The bottom surface of the turbid liquid storage area 24 is inclined, and a water collection pit 33 is opened at the lower end of the inclined surface. The submersible pump 28 is installed in the water collection pit 33.

[0025] A top cover 34 is provided on the mounting hole of the turbid liquid extraction tank 26. A U-shaped through-pipe groove is opened on the top cover 34, and the outlet pipe of the submersible pump 28 extends out from the U-shaped through-pipe groove.

[0026] A valve is installed on the branch drain pipe 32.

[0027] The top of the storage pool 21 is provided with a cover 35.

[0028] The top cover 35 has a triangular cross-section. The middle part of the top cover 35 is installed on the partition plate 23, and the two sides of the top cover 35 are fixed to the storage pool 21 respectively.

[0029] The clear liquid storage tank 27 has a through-hole 36, through which the water pump 29's pumping pipe and clear liquid pipe 31 extend into the clear liquid storage area 25.

[0030] Level gauges are installed in the turbid liquid storage area 24 and the clear liquid storage area 25 respectively.

[0031] Submersible pump 28 is a submersible sludge pump.

[0032] Example 1: The turbid polyaluminum chloride solution after mixing and reaction in the mixing tank is transported to the filter press 22 through the main drain pipe 30 to obtain a clarified solution. The clarified solution is then transported to the clarified solution storage area 25 through the clear solution pipe 31. The branch drain pipe 32 is opened, and the turbid polyaluminum chloride solution is transported to the turbid solution storage area 24 for storage. When it is necessary to output the clarified solution, the water pump 29 is started to draw the clarified polyaluminum chloride solution from the clear solution storage area 25 into a storage tank, providing the clarified polyaluminum chloride solution. The water pump 29 draws the clarified polyaluminum chloride solution from the clear solution storage area 25 into a drum dryer for drying, and then outputs it by a conveyor to obtain powdered polyaluminum chloride. The submersible pump 28 is started to pump the turbid polyaluminum chloride solution upwards into a storage tank, providing the turbid polyaluminum chloride solution. This can adapt to the needs of different customers.

[0033] The filter press 22 is a plate and frame filter press. The bottom surface of the turbid liquid storage area 24 is inclined, which allows the sediment in the turbid liquid to flow to a lower position and then be pumped out by a submersible sludge pump, preventing sediment accumulation. The turbid liquid extraction tank 26 has installation holes for easy hoisting of the submersible pump 28. After installation, the installation holes are covered by the top cover 34 to prevent impurities from entering. At the same time, the outlet pipe of the submersible pump 28 can also extend from the U-shaped through-hole. The U-shaped through-hole is easier to install than the circular through-hole, and it is also easier to open the top cover 34. The cross-section of the top cover 35 is triangular to prevent rainwater accumulation. The pump 29's suction pipe and clear liquid pipe 31 extend into the clear liquid storage area 25 through the through-hole 36, respectively. The water pipes are centrally installed for easy management.
