[0002] With the continuous development of industrial production and science and technology, brine has been widely used in many fields, such as chemical industry, pharmaceutical industry, food processing, etc. However, brine often contains various impurities, which will have adverse effects on subsequent production processes and product quality. Therefore, effective filtration of brine has become a key link. Traditional brine filters have some problems during use. On the one hand, the filter screen is easily clogged during the filtration process, resulting in a decrease in filtration efficiency. Frequent replacement of the filter screen not only increases the cost, but also causes equipment downtime for too long, affecting production progress. On the other hand, when the filter screen needs to be replaced, the existing filters are often complex in structure and difficult to disassemble. Professional tools and professional skills are required. The operation is difficult and labor-intensive, and cannot meet the requirements of quick and convenient disassembly. Utility Model Content

Conversely, the filter plate 15 can also be fixed by the L-shaped slide 14. The inner wall of the bottom of the box body 11 is fixedly connected with a pulse valve 16, and the outer wall of the top of the pulse valve 16 is fixedly connected with a nozzle plate 17. The inner wall of the box body 11 close to the pulse valve 16 is fixedly connected with a discharge pipe 18, and the outer wall of the box body 11 is fixedly connected with a support frame 19.

[0022] The nozzle plate 17 is arranged inside the box body 11, and the gas is ejected from the nozzle on the nozzle plate 17 in a pulsed manner through the pulse valve 16 to clean the filter 151 on the filter plate 15. The outer wall of the top of the pull ring 12 contacts the outer wall above the box body 11, and the sliding groove 111 is arranged in a circular array along the axial center point of the box body 11. The interior of the discharge pipe 18 is connected to the interior of the box body 11, and the liquid in the box body 11 can be discharged through the discharge pipe 18.

[0023] The sealing device 2 includes a cover plate 21, the inner wall of the top of the cover plate 21 is fixedly connected to the feed pipe 22, the outer wall of the feed pipe 22 is fixedly connected to the flange 221, the outer wall of the bottom of the cover plate 21 is provided with a clamping groove 23, the inner wall of the clamping groove 23 is fixedly connected to the positioning rod 24, the outer wall of the positioning rod 24 is slidably connected to the clamping plate 25, and the outer wall of the clamping plate 25 is fixedly connected to the extrusion spring 26.

[0024] The clamping groove 23 is arranged in a circular array at the axial center point of the cover plate 21. The outer wall of the extrusion spring 26 away from the clamping plate 25 is fixedly connected to the inner wall of the clamping groove 23. The extrusion spring 26 is arranged on the outside of the positioning rod 24. The clamping plate 25 is squeezed to slide along the clamping groove 23 through the positioning rod 24. The extrusion spring 26 is squeezed and stores force. When the clamping plate 25 is released, the elastic force restored by the extrusion spring 26 causes the clamping plate 25 to be reset.

[0025] The outer wall of the top of the sealing gasket 13 contacts the inner wall of the top of the cover plate 21, the outer wall of the box body 11 is slidably connected to the outer wall of the splint 25, and the outer wall of the pull ring 12 is slidably connected to the outer wall of the splint 25.

When the sealing gasket 13 contacts the cover plate 21, the extrusion spring 26 releases the elastic force to reset the splint 25, and the cover plate 21 is clamped on the box body 11, and the box body 11 is sealed. When the covering device 2 needs to be removed, the pull ring 12 is pushed upward so that it slides upward along the sliding groove 111 and contacts the inclined surface of the splint 25. Continue to push upward to squeeze the splint 25 inward along the clamping groove 23 again, and finally separate from the box body 11, and then take out the covering device 2.

[0026] Working principle: During the filtration process, the brine enters the filter through the feed pipe 22 on the sealing device 2. The flange 221 on the outer wall of the feed pipe 22 is used to connect to the external pipeline. The brine flows from the feed pipe 22 into the box 11 of the filter device 1, and then passes through the filter screen 151 on the filter plate 15 for filtration, and then flows out from the discharge pipe 18 at the bottom of the box 11. When the filtration is completed, the pulse valve 16 is started to make the gas ejected in a pulse manner from the nozzle on the nozzle plate 17 fixedly connected to the outer wall of the top of the pulse valve 16. The ejected gas cleans the filter screen 151 on the filter plate 15 to prevent the filter screen 151 from being blocked.

[0027] When the filter screen 151 needs to be replaced, first remove the cover device 2 and push the pull ring 12 upwards to make it slide upwards along the sliding groove 111 opened on the outer wall of the box body 11. When the pull ring 12 contacts the inclined surface of the clamping plate 25, continue to push it upwards to squeeze the clamping plate 25 inwards along the clamping groove 23, and finally the clamping plate 25 slides and separates from the box body 11. Then the cover device 2 can be taken out, and the rotating shaft handle 152 is rotated to make the filter plate 15 slide along the bottom of the L-shaped slide groove 14, and then the filter plate 15 is pulled out along the vertical slide groove of the L-shaped slide groove 14 to clean and replace the filter screen 151 on the filter plate 15. Conversely, push the filter plate 15 into the interior of the box body 11 along the vertical slide groove of the L-shaped slide groove 14, and rotate the rotating shaft handle 152 to make the filter plate 15 slide along the bottom of the L-shaped slide groove 14 again to achieve fixation.

[0028] Then the cover 21 is slid downward along the outer wall of the box body 11. During the sliding process, the splint 25 contacts the outer wall of the box body 11 and is squeezed inward along the clamping groove 23 through the positioning rod 24 through the inclined surface on the splint 25. At this time, the extrusion spring 26 is compressed and stored. When the sealing gasket 13 contacts the cover 21, the extrusion spring 26 releases the elastic force to reset the splint 25, and the cover 21 is clamped on the box body 11, thereby realizing the sealing of the filter device 1. The support frame 19 outside the box body 11 ensures the stable operation of the entire equipment.
