Description

Technical Field

[0001] This utility model belongs to the field of chemical material filtration technology, specifically relating to a filtration device that is easy to clean. Background Technology

[0002] In the production process of chemical materials, impurities are present in the chemical materials, requiring filtration devices for removal. However, after prolonged use, impurities trapped by the filter screen accumulate at the screen, causing blockage and affecting the filtration efficiency. The filter screen needs to be cleaned. Currently, chemical material filtration devices require interruption of filtration before the cleaned filter screen can be reinstalled, further impacting the filtration efficiency. Utility Model Content

[0019] Please see Figures 1-5 The present invention provides the following technical solution: a filter device that is easy to clean, including a supporting inner barrel 1, four evenly distributed liquid flow gaps 11 on the side wall of the supporting inner barrel 1, four evenly distributed outward-expanding filter screens 2 detachably connected to the outside of the supporting inner barrel 1, four evenly distributed adjustable closed arc plates 3 engaging on the side wall of the supporting inner barrel 1, a telescopic rod 31 fixedly connected to the inner wall of the adjustable closed arc plate 3, and four evenly distributed filter liquid collection chambers 4 fixedly connected to the outer wall of the supporting inner barrel 1.

[0020] In this implementation scheme: Under normal conditions, the four locking rings 21 are respectively inserted into the corresponding positions of the four sealing locking groove plates 12. The sealing locking groove plates 12 and the locking rings 21 are sealed together by a sealing strip. The adjustable closing arc plate 3 extends outward under the drive of the telescopic rod 31, forming a gap between the adjustable closing arc plate 3 and the supporting inner barrel 1 for material flow. The material flows into the outward-expanding filter screen 2 through the gap between the adjustable closing arc plate 3 and the supporting inner barrel 1, and after being filtered by the outward-expanding filter screen 2, it is discharged into the filtrate collection chamber 4 and discharged outward through the drain pipe 41. When it is necessary to clean the outward-expanding filter screen 2, the adjustable closing arc plate 3 is pulled back by the telescopic rod 31, and the adjustable closing arc plate 3 seals the liquid flow gap 11, and cooperates with the sealing gasket 13 to seal the liquid flow gap. The gap between the opening 11 and the adjustable closed arc plate 3 is sealed. After the material in the outward-expanding filter screen 2 is filtered, the operator removes the locking connecting ring 21 from the sealing locking groove plate 12, removes the outward-expanding filter screen 2, cleans the outward-expanding filter screen 2, and replaces the missing parts of the outward-expanding filter screen 2 with new ones. Then, the adjustable closed arc plate 3 is opened again, and the above operation is repeated to disassemble, replace and clean the four outward-expanding filter screens 2 in turn. During the cleaning and replacement of the outward-expanding filter screens 2, the material is still filtered through the other outward-expanding filter screens 2 to avoid interruption of material filtration, which can improve the material filtration efficiency. Moreover, the outward-expanding filter screen 2 expands and bends outward, which can effectively increase its own filtration area, thereby further improving the material filtration efficiency.

[0021] Four sealing locking groove plates 12 are fixedly connected to the outer wall of the inner support tank 1. The four sealing locking groove plates 12 correspond to the positions of four liquid flow gaps 11 respectively. The coverage area of ​​the sealing locking groove plates 12 is larger than the opening area of ​​the liquid flow gaps 11. By setting the sealing locking groove plates 12, it is easy to connect the inner support tank 1 with the outward expansion filter screen 2. The area of ​​the sealing locking groove plates 12 is larger, so that the material flowing out of the inner support tank 1 can completely enter the outward expansion filter screen 2.

[0022] A sealing gasket 13 is fixedly connected to the inner wall of the liquid flow gap 11, and the inner support tank 1 is sealed to the adjustable closed arc plate 3 through the sealing gasket 13; by setting the sealing gasket 13, the gap between the liquid flow gap 11 and the adjustable closed arc plate 3 can be sealed to prevent material leakage.

[0023] The side wall of the outward-expanding filter screen 2 is fixedly connected with a snap-fit ​​connecting ring 21, which is inserted into the sealing snap-fit ​​groove plate 12. By setting the snap-fit ​​connecting ring 21, it is easy to connect the outward-expanding filter screen 2 to the sealing snap-fit ​​groove plate 12. During installation, the snap-fit ​​connecting ring 21 is inserted into the sealing snap-fit ​​groove plate 12.

[0024] The inner walls of the four telescopic rods 31 are fixedly connected with support rings 32; by setting the support rings 32, the telescopic rods 31 can be supported so that the position of the adjustable closed arc plate 3 can be adjusted.

[0025] A drain pipe 41 is fixedly connected to the side wall of the filtrate collection chamber 4, and the drain pipe 41 is connected to the internal space of the filtrate collection chamber 4. The drain pipe 41 is connected to an external conveying pipeline. After the material filtered by the externally expanded filter screen 2 enters the filtrate collection chamber 4, it is discharged through the drain pipe 41.

[0026] An inner lifting plate 5 is fixedly connected to the inner wall of the inner support barrel 1. The support frame 32 is fixedly connected to the inner lifting plate 5. The top of the inner lifting plate 5 is higher than the bottom inner wall of the liquid flow gap 11. By setting the inner lifting plate 5, the bottom height of the material in the inner support barrel 1 can be raised so that the material can be discharged outward from the liquid flow gap 11 under the action of gravity, thus avoiding the accumulation of some material in the inner support barrel 1 that cannot be discharged.

[0027] The working principle and usage process of this utility model are as follows: Under normal conditions, the four locking connecting rings 21 are respectively inserted into the corresponding positions of the four sealing locking groove plates 12. The sealing locking groove plates 12 and the locking connecting rings 21 are sealed together by a sealing strip. The adjustable closed arc plate 3 extends outward under the drive of the telescopic rod 31, forming a gap between the adjustable closed arc plate 3 and the supporting inner barrel 1 to allow material flow. The material flows through the gap between the adjustable closed arc plate 3 and the supporting inner barrel 1 into the outward-expanding filter screen 2, and after being filtered by the outward-expanding filter screen 2, it is discharged into the filtrate collection chamber 4 and discharged outward through the drain pipe 41. The outward-expanding filter screen 2 is cleaned when necessary. At that time, the adjustable closed arc plate 3 is pulled back by the telescopic rod 31, and the adjustable closed arc plate 3 seals the liquid flow gap 11. The sealing gasket 13 is used to seal the gap between the liquid flow gap 11 and the adjustable closed arc plate 3. After the material in the outward-expanding filter screen 2 is filtered, the staff removes the locking connecting ring 21 from the sealing locking groove plate 12, removes the outward-expanding filter screen 2, cleans the outward-expanding filter screen 2, and replaces the missing parts of the outward-expanding filter screen 2 with new ones. Then the adjustable closed arc plate 3 is opened again, and the above operation is repeated to disassemble, replace and clean the four outward-expanding filter screens 2 in turn.
