Description

Technical Field

[0001] This utility model belongs to the field of chemical production technology, specifically a chemical filtration device used in chemical production. Background Technology

[0002] Chemical production refers to a process that uses chemical reactions to produce desired products or to change the properties of substances.

[0003] In chemical production processes, it is necessary to remove impurities, solid particles, and harmful substances from liquids or gases. Common filters include candle filters, sealed plate filters, and chemical bag filters. In typical bag filters, the fluid containing solid particles enters from one side of the filter. As the fluid passes through the filter bag, the solid particles are trapped inside the filter bag, while the filtered fluid continues to flow to the outlet through the filter bag.

[0004] During the process of filtering raw materials using a bag filter, solid particles accumulated on and inside the filter bag will gradually form a filter cake. The formation of the filter cake will block the filter pores on the surface of the filter bag, thereby increasing the filtration resistance and ultimately reducing the fluid filtration effect.

[0005] Therefore, this utility model provides a chemical filtration device for chemical production. Utility Model Content

Inside, the liquid enters the filter bag 13 for filtration. At this time, the first motor 15 is turned on, and the output end of the first motor 15 drives the rotating shaft 16 to rotate. The rotational force of the rotating shaft 16 causes the connecting rod 18 to rotate, and at the same time, the striking balls 19 swing towards the side wall of the filter bag 13 along with the connecting rod 18. The filter bag 13 vibrates due to the multiple striking balls 19, causing the liquid to flow quickly in the middle of the filter bag 13 and pass through the filter bag 13. The filtered liquid is discharged through the outlet 14 through the filter bag 13. The rotating striking balls 19 of the above structure can continuously hit the surface of the filter bag 13, which can quickly separate solid particles from liquid. During liquid filtration, the filtration efficiency of the filter box 1 is maintained, effectively reducing the accumulation of filtered cake or particles on the surface of the filter bag 13, reducing the clogging of the surface of the filter bag 13, and maintaining a good filtration effect during continuous liquid filtration.

Insert the filter bag 13 into the groove 21 and press the locking block 26 downwards. The spring 25 will elastically contract. Rotate the filter bag 13 to make the locking block 26 slide inside the groove 21. When the locking block 26 moves to the position of the through groove 23 and coincides with it, the locking block 26 is elastically stretched into the through groove 23 by the spring 25. The filter bag 13 is fixed by the locking block 26.

[0026] like Figure 1 and Figure 5 As shown, a second motor 3 is installed on the outer wall of the filter box 1; the output end of the second motor 3 passes through the middle of the filter box 1; a bevel gear 31 is fixedly connected to the output end of the second motor 3; a rotating plate 32 is rotatably connected to the inner wall of the filter box 1; a bevel gear ring 33 is fixedly connected to the bottom of the rotating plate 32; the bevel gear 31 and the bevel gear ring 33 are meshed; a support rod 34 is fixedly connected to the bottom of the rotating plate 32; the support rod 34 is L-shaped; a brush bristle 35 is fixedly connected to the middle of the support rod 34; the brush bristle 35 is in contact with the outer wall of the filter bag 13; during operation, the second motor 3 is turned on, causing the output end of the second motor 3 to drive... The bevel gear 31 rotates, driving the bevel gear ring 33 to make the rotating plate 32 rotate on the inner wall of the filter box 1. As the rotating plate 32 rotates, the bristles 35 continuously clean the outer wall of the filter bag 13. Through the above structure, the bristles 35 rotate closely against the outer wall of the filter bag 13, directly scraping off the accumulation of particulate matter on the surface of the filter bag 13. When rotating, the bristles 35 can cover the entire surface of the filter bag 13. Together with the tapping ball 19, it can maintain the filtration performance of the filter bag 13, reduce downtime caused by clogging or damage to the surface of the filter bag 13, and improve the continuity and stability of chemical production.

[0027] like Figures 1 to 3As shown, a water storage tank 4 is fixedly connected to the bottom of the tank cover 11; multiple spray heads 41 are fixedly connected to the bottom of the water storage tank 4; the multiple spray heads 41 are equidistantly distributed; a water inlet pipe 42 is fixedly connected to the middle of the water storage tank 4; the water inlet pipe 42 passes through the middle of the tank cover 11; during operation, after liquid filtration, the end of the water inlet pipe 42 is connected to a water pump, and the water pump discharges water to the middle of the water inlet pipe 42, allowing the water to flow into the interior of the water storage tank 4 through the water inlet pipe 42, and the water is sprayed out through the multiple spray heads 41. The sprayed water cleans the filter box 1 and the filter bag 13. Through the above structure, the cleaning liquid can be evenly sprayed inside the filter box 1 and the filter bag 13, so that all corners inside the filter box 1 are thoroughly cleaned, reducing liquid residue inside the filter box 1, reducing secondary pollution to other filtered liquids, and improving product quality.

[0028] like Figure 5 As shown, a fixed rod 5 is fixedly connected to the middle of the support rod 34; a scraper 51 is fixedly connected to the end of the fixed rod 5; the middle of the scraper 51 is in contact with the inner wall of the filter box 1; during operation, when the liquid is filtered through the filter bag 13, the liquid comes into contact with the inside of the filter box 1. As the support rod 34 rotates, the scraper 51 scrapes the inner wall of the filter box 1, thereby removing the liquid remaining on the inner wall of the filter box 1. Through the above structure, the scraper 51 can remove the liquid adhering to the inner wall of the filter box 1, reduce the liquid residue on the inner wall of the filter box 1, reduce the pollution caused when other liquids enter the filter box 1 for filtration, and allow the liquid to be completely discharged.

[0029] like Figure 1 and Figure 2 As shown, a filter box 6 is fixedly connected to the middle of the water inlet pipe 42; a filter plate 61 is fixedly connected to the middle of the filter box 6; during operation, when the water flows through the middle of the water inlet pipe 42, it first enters the interior of the filter box 6, and the filter plate 61 filters the impurities in the water, so that the filtered clean water is discharged into the water storage tank 4. The above structure can effectively reduce the impurities in the clean water flow from entering the water storage tank 4, reduce the wear and blockage caused by impurities passing through the middle of multiple spray heads 41, and keep the water flow clean.

[0030] like Figure 2 and Figure 3 As shown, a sealing strip 7 is fixed to the bottom of the cover 11; the sealing strip 7 is in contact with the inner wall of the filter box 1; when liquid enters the filter box 1 during operation, the sealing strip 7 seals the cover 11 and the filter box 1. The sealing strip 7 can isolate the environment inside the filter box 1 from the environment outside, effectively fill the tiny gap at the top connection of the filter box 1, and reduce the leakage of liquid or gas under high pressure or high temperature.

[0031] During operation, the filter bag 13 is installed at the fixed ring 12 using the mounting component 2. Liquid generated during chemical production is discharged into the filter box 1 through the inlet pipe 10. The liquid enters the filter bag 13 for filtration. At this time, the first motor 15 is turned on, and its output drives the rotating shaft 16 to rotate. The rotational force of the rotating shaft 16 causes the connecting rod 18 to rotate, while the striking balls 19 swing towards the side wall of the filter bag 13 along with the connecting rod 18. Multiple striking balls 19 strike the middle of the filter bag 13, causing the filter bag 13 to be filtered through multiple impacts. The impact of the ball 19 generates vibration, causing the liquid to flow rapidly through the middle of the filter bag 13. The filtered liquid is then discharged through the outlet 14. When installing the filter bag 13, first, place the two fixing plates 24 into the groove 21 corresponding to the mounting slots 22. Then, press the locking block 26 downwards, causing the spring 25 to elastically contract. Rotate the filter bag 13 to allow the locking block 26 to slide inside the groove 21. When the locking block 26 moves to the position of the through groove 23 and aligns with it, the locking block 26 is elastically stretched into the through groove by the spring 25. Inside 23, the filter bag 13 is fixed by the locking block 26. The second motor 3 is turned on, causing the output end of the second motor 3 to drive the bevel gear 31 to rotate. The bevel gear 31 drives the bevel gear ring 33 to make the rotating plate 32 rotate on the inner wall of the filter box 1. As the rotating plate 32 rotates, the brush bristles 35 continuously clean the outer wall of the filter bag 13. After liquid filtration, the end of the water inlet pipe 42 is connected to the water pump. The water pump discharges water to the middle of the water inlet pipe 42, and the water flows into the water storage tank 4 through the water inlet pipe 42. The water is sprayed out through multiple spray nozzles 41. The sprayed water... The filter box 1 and filter bag 13 are cleaned. When the liquid is filtered through the filter bag 13, the liquid comes into contact with the inside of the filter box 1. As the support rod 34 rotates, the scraper 51 scrapes the inner wall of the filter box 1, thereby removing the liquid remaining on the inner wall of the filter box 1. When the water flows through the middle of the inlet pipe 42, it first enters the filter box 6. The filter plate 61 filters the impurities in the water, and the filtered clean water is discharged into the water storage tank 4. When the liquid enters the filter box 1, the sealing strip 7 seals the box cover 11 and the filter box 1.
