[0003] After searching, the patent number CN220237907U discloses a chemical filtering device for chemical production. The filtering device is convenient for preventing the filter plate from being placed through a limit table. The filter plate of the first layer is used for filtering debris particles, and the filter plate of the second layer adopts an activated carbon filter plate to remove fine substances in the wastewater, decolorize, dechlorinate, remove organic matter and heavy metals, as well as bacteria, viruses, radioactive pollutants and other pollutants from the wastewater, so that the wastewater meets the discharge standards. When the filter plate needs to be replaced, the filter plate is taken out through the upper part of the filtering device, so that there is no need to set a disassembly port at the outer end of the filtering device, avoiding water leakage caused by poor sealing, thereby improving the practicality of the device.

[0004] However, when replacing the filter plate, the above-mentioned filter device needs to be disassembled through the cooperation of multiple components, which takes a lot of time. At the same time, the filtering work is interrupted during the removal of the filter plate, resulting in the inability to perform the filtering work stably and continuously, thereby reducing the filtering efficiency.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The embodiment of the utility model discloses a chemical filtering device used in chemical production.

[0027] The utility model provides Figure 1-3 A chemical filtering device for chemical production shown in the figure comprises a filter cartridge 1, a filter plate 2 is placed on the upper end of the inner wall of the filter cartridge 1, an annular protrusion is provided at the lower end of the inner wall of the filter cartridge 1, the top of the annular protrusion contacts and cooperates with the filter plate 2, a support rod 3 is fixedly provided at the upper end of the inner wall of the filter cartridge 1, a conversion plate 4 is rotatably sleeved on the rod wall of the support rod 3, a sealing strip 5 is fixedly provided at the bottom of the conversion plate 4, the sealing strip 5 is pressed and contacted with the top of the filter plate 2, cleaning operation holes are opened at the upper ends of both sides of the filter cartridge 1, and the outer sides of the two cleaning operation holes are covered with cover plates 11, the cover plate 11 contacts and cooperates with the outer wall of the filter cartridge 1, and is screwed and fixed to the side of the filter cartridge 1 by bolts 12;

[0028] Grooves are provided on both sides of the outer wall of the conversion plate 4 , and a positioning mechanism for limiting the position of the conversion plate 4 is provided between the grooves and the inner wall of the filter cartridge 1 .

[0029] When performing chemical filtration, since the conversion plate 4 is inclined and the sealing strip 5 is in contact with the filter plate 2, the right side of the filter plate 2 can be used at this time, so that the chemical raw materials can be filtered through the right side of the filter plate 2. After the right side of the filter plate 2 has been used for a long time, the conversion plate 4 can be rotated under the support of the support rod 3, so that the conversion plate 4 covers the right side of the filter plate 2 and exposes the left side of the filter plate 2. At this time, the chemical raw materials can continue to be filtered through the left side of the filter plate 2, ensuring that the filtration work is carried out more continuously. At the same time, when the left side filter plate 2 is filtering, the right side cover plate 11 is removed, and the operator can quickly remove and clean the filtered impurities accumulated on the right side of the filter plate 2 by cleaning the operation hole, so that after the left side of the filter plate 2 has been filtered for a certain period of time, the right area of ​​the filter plate 2 can still perform effective filtering work, thereby improving the use effect of the filter plate 2 and ensuring that the filtration work is carried out continuously and stably.

[0030] In order to determine the position of the conversion plate 4 after the conversion plate 4 is rotated, as shown in FIG. Figure 1-2 As shown, the positioning mechanism includes a movable plate 6, which is slidably arranged in the groove, and a positioning rod 7 is fixedly arranged at the lower end of the outer wall, a spring 8 is fixedly arranged between the movable plate 6 and the inner wall of the groove, a guide rod 10 is fixedly arranged on the inner wall of the groove, and the guide rod 10 is slidably arranged inside the movable plate 6, and a plurality of positioning grooves 9 are provided on both sides of the inner wall of the filter cartridge 1 in a symmetrical manner, the positioning rod 7 is plugged into the positioning groove 9, and the plurality of positioning grooves 9 are symmetrically arranged around the central axis of the support rod 3.

[0031] When the conversion plate 4 is rotated and replaced, the movable plates 6 on both sides of the conversion plate 4 can be pressed, so that the movable plates 6 can squeeze the springs 8 with the support of the guide rods 10, and the positioning rods 7 can be taken out of the positioning grooves 9. Then, after the conversion plate 4 is replaced, the movable plate 6 is released. Under the elastic force recovery of the spring 8, the positioning rods 7 can rebound quickly and be inserted into the other positioning groove 9, so that the positions of the movable plates 6 and the conversion plate 4 are determined to ensure the stable filtering work.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
