Description

Technical Field

[0001] This utility model relates to the field of phosphoric acid impurity filtration technology, and in particular to a phosphoric acid filtration device. Background Technology

[0002] With the acceleration of industrialization, phosphoric acid, as an important chemical raw material and by-product, is widely used in the production processes of industries such as chemical, metallurgy, and power. However, phosphoric acid solutions usually contain suspended particles, metal ions, unreacted raw materials, and other substances that may affect the quality of phosphoric acid or its subsequent use, making it impossible for phosphoric acid to meet the required purity standards in industrial or laboratory applications. Therefore, phosphoric acid needs to be filtered through a phosphoric acid filtration device before use.

[0003] Traditionally, phosphoric acid solutions require filtration using high-density membranes or screens before reuse. However, in actual use, impurities in the phosphoric acid solution can accumulate on the membrane, causing blockage and affecting the filtration effect. This necessitates frequent disassembly, cleaning, or replacement of the filter, which reduces work efficiency. Therefore, a phosphoric acid filtration device is proposed to solve these problems. Utility Model Content

A telescopic cylinder is fixedly connected to the top of the housing, and a top cover is fixedly connected to the output end of the telescopic cylinder. A support member is fixedly connected to the bottom of the housing, and a bottom cover is fixedly connected to the top of the support member. A flow component is installed in the middle of the housing. Connecting plates are fixedly connected to both the left and right sides of the housing.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a phosphoric acid filtration device, comprising a housing 1, a telescopic cylinder 2 fixedly connected to the top of the housing 1, a top cover 14 fixedly connected to the output end of the telescopic cylinder 2, a support member 16 fixedly connected to the inner bottom of the housing 1, a bottom cover 15 fixedly connected to the top of the support member 16, a flow assembly installed in the middle of the housing 1, the flow assembly including an infusion pipe 18 fixedly connected to the middle of the top cover 14, a sliding groove 19 opened on the rear side of the housing 1, the infusion pipe 18 slidably connected to the middle of the sliding groove 19, and a bottom cover 15 fixedly connected to the bottom of the bottom cover 15. There is a liquid outlet pipe 17, the other end of which passes through the bottom of the box body 1. The left and right sides of the box body 1 are fixedly connected to the connecting plates 12, and the left and right sides of the box body 1 are slidably connected to the movable plates 13. The two connecting plates 12 and the movable plates 13 are rotatably connected to the opposite side of each other. The outer periphery of the multiple cross protrusions 21 is slidably connected to the rotating roller 8 and the winding roller 4. The outer periphery of the rotating roller 8 is fitted with a filter membrane 6. The other end of the filter membrane 6 is fixedly connected to the middle of the winding roller 4. The left and right sides of the box body 1 are provided with through grooves 11, and the filter membrane 6 passes through the through grooves 11. First, connect the inlet hose to the infusion connector 18 so that the phosphoric acid solution can enter the top cover 14. The phosphoric acid solution is filtered by the filter membrane 6 between the top cover 14 and the bottom cover 15. The filtered phosphoric acid solution flows into the bottom cover 15 and is discharged through the outlet connector 17. After a long period of filtration, drive the telescopic cylinder 2 to lift the top cover 14 upward. The top cover 14 drives the infusion connector 18 to move in the middle of the chute 19, thereby avoiding damage to the infusion connector 18 by collision, so that the filter membrane 6 is no longer squeezed by the top cover 14 and the bottom cover 15.

[0035] Reference Figure 1 , Figure 2 and Figure 4A drive assembly is installed on the outer side of one of the connecting plates 12. The drive assembly includes a servo motor 3, which is fixedly connected to the front side of one of the connecting plates 12. A cross protrusion 21 is fixedly connected to the output end of the servo motor 3. Support blocks 22 are fixedly connected to both the left and right sides of the housing 1. A rotating rod 23 is rotatably connected to the middle of the support block 22. Cross grooves 24 are opened on the front and rear sides of the rotating roller 8 and the winding roller 4. Multiple cross protrusions 21 are slidably connected to the middle of multiple cross grooves 24. After the top cover 14 and the bottom cover 15 are separated, the drive servo motor 3 drives the cross protrusion 21 to rotate, so that the cross protrusion 21 drives the winding roller 4 to rotate through the cross groove 24. Under the action of the winding roller 4, the blocked filter membrane 6 is pulled out and wound up. The rotating roller 8 releases the new filter membrane 6 under the traction of the winding roller 4 and moves it between the top cover 14 and the bottom cover 15. Then, the telescopic cylinder 2 drives the top cover 14 to move downward, thereby fixing the new filter membrane 6 between the top cover 14 and the bottom cover 15. This reduces the frequency of cleaning and disassembly by the staff and improves the filtration efficiency. At the same time, under the action of the support block 22 and the rotating rod 23, the filter membrane 6 can pass through the through groove 11, avoiding damage caused by friction between the filter membrane 6 and the edge of the through groove 11.

[0036] Reference Figure 1 , Figure 2 and Figure 4 The left and right sides of the box body 1 are fixedly connected to the fixing plates 7. The middle of the fixing plates 7 is slidably connected to the pull rod 10. The two ends of the pull rod 10 are respectively fixedly connected to the rear side of the two movable plates 13. The outer periphery of the pull rod 10 is fitted with a compression spring 9. After the filter membrane 6 is fully wound up by the take-up roller 4, the pull rod 10 is pulled under the support of the fixed plate 7 to move the movable plate 13, so that the cross protrusions 21 on the two movable plates 13 slide out of the cross grooves 24, thereby removing the take-up roller 4 and the rotating roller 8. At the same time, when the movable plate 13 is pulled, it will squeeze the compression spring 9 under the action of the fixed plate 7. After inserting the new rotating roller 8 and the take-up roller 4 into the cross protrusions 21 on the connecting plate 12, the pull rod 10 is released. Under the action of the compression spring 9, the movable plate 13 is pushed, so that the cross protrusions 21 on the movable plate 13 are inserted into the cross grooves 24 at the other end of the take-up roller 4 and the rotating roller 8, thereby quickly installing the take-up roller 4 and the rotating roller 8. After opening the front door of the box 1, the filter membrane 6 is passed through the through groove 11 and adhered to the take-up roller 4 for reuse.

[0037] Reference Figure 3 , Figure 5 and Figure 6The bottom cover 15 has a slot 20 on its top, and a rubber pad 25 is fixedly connected to the bottom of the slot 20. The bottom of the top cover 14 has a locking block 26 fixedly connected, which is slidably connected to the middle of the slot 20. A sealing ring 5 is fixedly connected to the bottom of the top cover 14. When the top cover 14 presses down to fix the filter membrane 6, the locking block 26 will squeeze the excess part of the filter membrane 6 into the slot 20 and fit it against the rubber pad 25 at the bottom of the slot 20. At the same time, the sealing ring 5 at the bottom of the top cover 14 will squeeze the filter membrane 6 to fit against the top of the bottom cover 15. Thus, under the dual action of the rubber pad 25 and the sealing ring 5, leakage is prevented.

[0038] Working principle: When the filter membrane 6 is clogged, the drive telescopic cylinder 2 drives the top cover 14 to separate from the bottom cover 15. The drive servo motor 3 drives the cross protrusion 21 to rotate, so that the cross protrusion 21 drives the winding roller 4 to wind up the filter membrane 6. At the same time, the rotating roller 8 is pulled to release the new filter membrane 6. Under the action of the support block 22 and the rotating rod 23, the filter membrane 6 can pass through the through groove 11, avoiding damage caused by friction between the filter membrane 6 and the edge of the through groove 11. After the new filter membrane 6 is pulled between the top cover 14 and the bottom cover 15, the drive telescopic cylinder 2 drives the top cover 14 to move downward, fixing the filter membrane 6 between the top cover 14 and the bottom cover 15, thereby reducing the frequency of cleaning and disassembly by the staff and improving the filtration efficiency.

[0039] After all the filter membranes 6 have been used, pull the lever 10 to move the movable plate 13, so that the movable plate 13 moves the cross protrusion 21 away from the take-up roller 4 and the rotating roller 8, so that the take-up roller 4 and the rotating roller 8 can be quickly removed. After placing the new take-up roller 4 and the rotating roller 8 between the movable plate 13 and the connecting plate 12, release the lever 10. Under the push of the compression spring 9, the take-up roller 4 and the rotating roller 8 can be quickly installed. The filter membrane 6 is passed through the through groove 11 and adhered to the take-up roller 4, thereby improving the installation and disassembly efficiency.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
