Technical Field

[0001] This utility model belongs to the field of continuous filtration devices, specifically relating to a continuous filtration device for liquid polyferric sulfate. Background Technology

[0002] Continuous filtration devices for liquid polyferric sulfate are mainly used to remove impurities from liquids, ensuring the purity and stability of liquid polyferric sulfate. This device is commonly used in water treatment, industrial wastewater treatment, and chemical production processes.

[0003] In the process of filtering liquid polyferric sulfate raw materials, existing continuous activated sand filtration equipment often produces scale on the inner wall of the tank. Since traditional continuous activated sand filtration equipment is generally an integrated structure, the scale inside is difficult to clean. As a result, the continuous activated sand filtration equipment affects its filtration effect and efficiency after long-term use. In addition, the support structure of the load-bearing frame of traditional tank filtration equipment is relatively simple, and the stability of supporting the filter tank is very limited. The tank is prone to tipping over when subjected to external impacts or vibrations.

[0004] Therefore, to address the problems of difficulty in cleaning scale from the inner wall of the tank and poor stability of the existing continuous activated sand filtration equipment, a continuous filtration device for liquid polyferric sulfate has been developed. By adding a lifting-type tank inner wall cleaning structure and an anti-tipping load-bearing frame structure to the continuous activated sand filtration equipment, the stability of the continuous activated sand filtration equipment during use can be effectively improved to prevent it from tipping over, and the efficiency and effectiveness of cleaning scale from the inner wall of the filtration equipment can be improved.

Two sets of movable plates 21 are symmetrically distributed front and back and fitted through the through holes 14 at the lower end of the limiting posts 18.

[0025] The frustum-shaped support frame, consisting of a base ring frame 1, rigid support legs 7, elastic support legs 8, and movable discs 21, provides stable support for the filter tank 2 and keeps its center of gravity stable to prevent it from tipping over during operation. The elastic support legs 8 can also cushion the filter tank 2 by deforming, further improving its stability during use. The hydraulic cylinder 20 can drive the two movable discs 21 to drive the cleaning brushes 23 to clean the scale inside the filter tank 2 along the inner wall, ensuring the filtration effect of the filter sand inside the filter tank 2.

[0026] Please see Figures 3-4In this embodiment, the sand washer 5 is installed through the upper end of the tank cover 3, and the lower end of the sand washer 5 is equipped with a water distributor 11. During use, the sand washer 5 can clean the activated sand that adsorbs pollutants to ensure the continuous use of the activated sand. An air lift pump 6 is installed at the lower end of the water distributor 11. The inner wall of the filter tank 2 is lined with filter sand. During use, the water distributor 11 can evenly distribute the liquid polyferric sulfate raw material to be filtered onto the activated sand in the filter tank 2 to improve the filtration effect of the liquid polyferric sulfate raw material. The inlet pipe 12 is installed at an angle on the outer wall of the water distributor 11, and the sand washer wastewater... The discharge pipe 13 is installed at an angle on the outer wall of the sand washer 5. The filtrate outlet pipe 10 is fixed to the front side of the outer wall of the filter tank 2. In use, the filtrate outlet pipe 10 can discharge the filtered liquid polyferric sulfate raw material to the outside. The upper end of the inlet pipe 12 is installed through the right outer wall of the filter tank 2. The upper end of the sand washer wastewater discharge pipe 13 is installed through the left outer wall of the filter tank 2. In use, the inlet pipe 12 can directly transport the liquid polyferric sulfate raw material to the water distributor 11 for dispersion treatment, while the sand washer wastewater discharge pipe 13 can transport the wastewater in the sand washer 5 to the outside of the filter tank 2 for discharge.

[0027] Please see Figures 4-6 In this embodiment, the gap between the two sets of movable discs 21 is in contact with the outer wall of the liquid inlet pipe 12 and the sand washing wastewater discharge pipe 13. The movable discs 21 and the cleaning brushes 23 are disposed on the inner wall of the filter tank 2. The outer wall of the cleaning brushes 23 is in contact with the inner wall of the filter tank 2. In use, the cleaning brushes 23 disposed on the inner wall of the filter tank 2 can efficiently clean the scale on the inner wall of the filter tank 2.

[0028] Please see Figures 5-6 In this embodiment, the inner wall of the sliding sleeve 19 is in contact with the outer wall of the guide rail 15, the outer wall of the sliding sleeve 19 is in contact with the inner wall of the limiting groove 16, and the inner wall of the through hole 14 is in contact with the outer wall of the limiting post 18. In use, the sliding sleeve 19 and the guide rail 15 can provide initial limiting assistance for the two sets of movable discs 21, while the through hole 14 and the limiting post 18 can further improve the stability of the two sets of movable discs 21 when they are raised and lowered.

[0029] In use, liquid polyferric sulfate raw material enters the filter tank 2 through the inlet pipe 12, and after being evenly distributed by the water distributor 11, it flows upward and countercurrently through the activated sand pile set in the filter tank 2 for filtration and discharge. During this process, the liquid polyferric sulfate raw material is filtered by the activated sand pile, the pollutant content in the water is reduced, while the pollutant content in the activated sand increases, and the pollutant content in the lower filter media layer is higher than that in the upper filter media layer.

[0030] When filtering activated sand, the activated sand at the bottom is lifted by the air lift pump 6 located on the inner wall of the lower end of the filter tank 2 under the action of the air compressor to the sand washer 5 on the inner wall of the upper end of the filter tank 2 for cleaning. The cleaned activated sand sinks back to the inner wall of the lower end of the filter tank 2 by its own weight, and the pollutants generated by the cleaning are discharged through the sand washing wastewater discharge pipe 13.

[0031] When it is necessary to clean the scale on the inner wall of the filter tank 2, the hydraulic cylinder 20 pushes the sliding sleeve 19 on the lifting frame 24 to make stable lifting and lowering adjustment along the guide rail 15 and the limiting groove 16, so as to push the limiting column 18 to drive the two sets of movable discs 21 and cleaning brushes 23 to clean the scale inside the filter tank 2 along the inner wall, so as to ensure the filtration effect of the filter sand in the filter tank 2.

[0032] When the filter tank 2 is in operation, the frustum-shaped load-bearing frame composed of the base ring frame 1, rigid support leg 7, elastic support leg 8 and movable plate 21 can provide stable support for the filter tank 2. In conjunction with the elastic support leg 8, the deformation can provide a certain buffer for the filter tank 2 to ensure the stability of the filter tank 2 during operation.

[0033] Through the above steps, the frustum-shaped support frame composed of the base ring frame 1, rigid support legs 7, elastic support legs 8, and movable disc 21 can provide stable support for the filter tank 2 and keep its center of gravity stable to prevent the filter tank 2 from tipping over during operation. The elastic support legs 8 can also provide some cushioning to the filter tank 2 by deforming, further improving the stability of the filter tank 2 during use. The hydraulic cylinder 20 can drive the two sets of movable discs 21 to drive the cleaning brushes 23 to clean the scale inside the filter tank 2 along the inner wall, so as to ensure the filtration effect of the filter sand inside the filter tank 2. This solves the problem that the scale on the inner wall of the tank is difficult to clean and the stability of the tank is poor when using existing continuous activated sand filtration equipment.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
