These additives can adjust reagent properties, promote reactions, increase yields, improve purity, etc. When producing chemical reagent additives, the raw materials of chemical reagent additives will be filtered to purify the raw materials of chemical reagent additives.

[0003] In the prior art, there is a patent document with a publication number of CN218740563U, which discloses a chemical reagent auxiliary filter, including a bottom plate, a protective box fixedly connected to the top of the bottom plate, a filter box provided in the inner cavity of the protective box, a concave block fixedly connected to the top and bottom of both sides of the inner cavity of the filter box, a connecting block movably connected to the inner cavity of the concave block, a filter screen fixedly connected to one side of the connecting block, a groove opened at the top of the connecting block, a plug rod inserted in the inner cavity of the groove, a baffle fixedly connected to the top of the concave block, and the plug rod and the baffle fixedly connected by mounting bolts. The patent document solves the problem that the existing filter device is extremely troublesome when disassembling the filter screen, increases the intensity of the work, and also greatly reduces the efficiency of disassembly and assembly, and is inconvenient for users to use by setting the groove, plug rod, baffle, mounting bolts and nuts, and using them in conjunction with the south pole and the north pole of the magnet.

[0004] The above-mentioned and prior art technologies have the following defects: when using the filter screen to filter the raw materials of chemical reagent additives, since the filter screen is a planar structure, the filtered impurities will be spread flat on the top of the filter screen, which can easily clog the filter screen, resulting in a decrease in the filtering efficiency of the filter screen and reducing the practicality of the filter.

[0005] Therefore, a chemical reagent auxiliary filter is proposed. Utility Model Content

[0006] The utility model aims to solve the problem that the filter screen is a plane structure, so the filtered impurities will be spread on the top of the filter screen, thus easily clogging the filter screen, and a chemical reagent auxiliary filter is proposed.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a chemical reagent auxiliary agent filter, comprising a filter box, a box cover is detachably installed on the upper end of the filter box, the surface of the box cover is fixed and connected to a liquid inlet hopper, the lower surface of the filter box is fixed and connected to a drain valve, the inner wall of the filter box is provided with a filter structure, the filter structure comprises a support plate, the support plate is fixedly connected to the filter box, the upper surface of the support plate is fixedly connected to a fixing rod, the surface of the fixing rod is slidably connected to a sliding tube, the arc surface of the sliding tube is fixedly connected to a filter plate, and the vertical cross-section of the filter plate is trapezoidal.

[0008] The effect achieved by the above components is: by setting up the filtering structure, when the raw materials of chemical reagent additives are filtered, since the vertical cross-section of the filter plate is trapezoidal, the impurities generated will slide downward along the surface of the filter plate, so that the impurities are accumulated at the lower end of the filter plate, while the upper end of the filter plate can still filter the raw materials normally, thereby preventing the filter plate from being blocked by impurities and improving the filtering efficiency of the filter plate.

[0009] Preferably, the side wall of the filter box is fixedly connected to a motor, the output end of the motor is fixedly connected to a transmission rod, the transmission rod is rotatably connected to the filter box, one end of the transmission rod is fixedly connected to a cam, and the arc surface of the sliding tube is fixedly connected to a rotating rod.

[0010] The effects achieved by the above components are: when the motor is turned on, the rotation of the output end of the motor will drive the transmission rod to rotate, the rotation of the transmission rod will drive the cam to rotate, the rotating rod will drive the sliding tube to slide upward due to the extrusion of the cam, the sliding of the sliding tube will drive the filter plate to slide, and when the cam is out of contact with the rotating rod, the filter plate will slide downward. Therefore, as the motor continues to rotate, the filter plate will slide back and forth in the vertical direction and shake, thereby accelerating the sliding of impurities along the surface of the filter plate downward, further avoiding the accumulation of impurities at the upper end of the filter plate and affecting the normal filtration of the raw materials by the filter plate.

[0011] Preferably, a buffer ring is fixedly connected to the arc surface of the rotating rod, and the buffer ring is a rubber ring.

[0012] The effect achieved by the above components is that when the cam contacts the buffer ring, the buffer ring can reduce the collision force between the rotating rod and the cam, thereby preventing the rotating rod and the cam from being damaged.

[0013] Preferably, the fixing rod is in the shape of a regular hexagonal prism.

[0014] The effect achieved by the above components is that the fixing rod in the hexagonal prism structure can limit the moving path of the sliding tube, so that the rotating rod can be aligned with the cam.

[0015] Preferably, a guide block is fixedly connected to the upper end of the fixing rod, and the guide block is in a hexagonal pyramid structure.

[0016] The effect achieved by the above components is that the guide block with a hexagonal pyramid structure guides the sliding path of the slide tube, thereby facilitating the slide tube to be sleeved on the surface of the fixed rod with a regular hexagonal prism structure.

[0017] Preferably, a retaining ring is fixedly connected to the upper surface of the filter plate.

[0018] The effect achieved by the above components is that when impurities need to be cleaned, the retaining ring can prevent the impurities from being scattered from the surface of the filter plate after the filter plate is taken out of the filter box.

[0019] Preferably, a handle is fixedly connected to the upper surface of the filter plate.

[0020] The effect achieved by the above components is: by providing a handle, after a large amount of impurities are accumulated on the surface of the filter plate, the filter plate can be easily moved and taken out of the filter box.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] In the utility model, by setting up a filtering structure, when filtering the raw materials of chemical reagent additives, since the vertical cross-section of the filter plate is trapezoidal, the generated impurities will slide downward along the surface of the filter plate, so that the impurities are accumulated at the lower end of the filter plate, while the upper end of the filter plate can still filter the raw materials normally, thereby preventing the filter plate from being blocked by impurities and improving the filtering efficiency of the filter plate.

[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0031] like Figure 1-Figure 5 As shown, the utility model provides a chemical reagent auxiliary filter, including a filter box 1, the upper end of the filter box 1 is detachably mounted with a box cover 2, the surface of the box cover 2 is fixed and connected with a liquid inlet hopper 3, the lower surface of the filter box 1 is fixed and connected with a drain valve 4, the inner wall of the filter box 1 is provided with a filter structure 5, the filter structure 5 includes a support plate 501, the support plate 501 is fixedly connected to the filter box 1, the upper surface of the support plate 501 is fixedly connected with a fixing rod 502, the surface of the fixing rod 502 is slidably connected with a sliding pipe 503, the arc surface of the sliding pipe 503 is fixedly connected with a filter plate 504, the vertical cross-section of the filter plate 504 is trapezoidal, the side wall of the filter box 1 is fixedly connected with a motor 505, the output end of the motor 505 is fixedly connected with a transmission rod 506, the transmission rod 506 is rotatably connected to the filter box 1, one end of the transmission rod 506 is fixedly connected with a cam 507, the arc surface of the sliding pipe 503 is fixedly connected with a rotating rod 508, the motor 505 is turned on, the motor 50 The output end of the motor 505 rotates to drive the transmission rod 506 to rotate, and the transmission rod 506 rotates to drive the cam 507 to rotate. The rotating rod 508 drives the slide tube 503 to slide upward due to the extrusion of the cam 507, and the sliding of the slide tube 503 drives the filter plate 504 to slide. When the cam 507 is out of contact with the rotating rod 508, the filter plate 504 slides downward. Therefore, as the motor 505 continues to rotate, the filter plate 504 reciprocates in the vertical direction and shakes, thereby accelerating the impurities to slide downward along the surface of the filter plate 504, further avoiding the accumulation of impurities on the upper end of the filter plate 504 and affecting the normal filtering of the raw materials by the filter plate 504. The arc surface of the rotating rod 508 is fixedly connected with a buffer ring 509, and the buffer ring 509 is a rubber ring. When the cam 507 contacts the buffer ring 509, the buffer ring 509 can reduce the collision force between the rotating rod 508 and the cam 507, thereby preventing the rotating rod 508 and the cam 507 from being damaged.

[0032] like Figure 2-Figure 5As shown, the fixing rod 502 is in the form of a regular hexagonal prism structure. The fixing rod 502 in the form of a hexagonal prism structure can limit the moving path of the sliding tube 503, so that the rotating rod 508 can be aligned with the cam 507. The upper end of the fixing rod 502 is fixedly connected with a guide block 510. The guide block 510 is in the form of a hexagonal pyramid structure. The guide block 510 in the form of a hexagonal pyramid structure can guide the sliding path of the sliding tube 503, so as to facilitate the sliding tube 503 to be sleeved on the surface of the fixing rod 502 in the form of a regular hexagonal prism structure. The upper surface of the filter plate 504 is fixedly connected with a retaining ring 511. When impurities need to be cleaned, the retaining ring 511 can prevent impurities from being spilled from the surface of the filter plate 504 after the filter plate 504 is taken out of the filter box 1. The upper surface of the filter plate 504 is fixedly connected with a handle 512. By setting the handle 512, after a large amount of impurities are accumulated on the surface of the filter plate 504, it is convenient to move the filter plate 504 and take it out of the filter box 1.

[0033] The overall working principle is that when the raw materials of chemical reagent additives need to be filtered, the box cover 2 is first removed, and then the filter plate 504 is moved with the help of the handle 512. The movement of the filter plate 504 will drive the slide tube 503 to move. When the slide tube 503 slides along the surface of the guide block 510, the guide block 510 with a hexagonal pyramid structure will guide the sliding path of the slide tube 503, so that the slide tube 503 is conveniently sleeved on the surface of the fixed rod 502, and the fixed rod 502 with a hexagonal prism structure can limit the moving path of the slide tube 503, thereby The rotating rod 508 can be aligned with the cam 507, and then the box cover 2 is closed, and the raw materials of the chemical reagent additives are poured into the liquid inlet hopper 3. When the raw materials flow through the filter plate 504, the filter plate 504 will be filtered. Since the vertical section of the filter plate 504 is trapezoidal, the impurities generated will slide downward along the surface of the filter plate 504, so that the impurities are accumulated at the lower end of the filter plate 504, while the upper end of the filter plate 504 can still filter the raw materials normally, thereby preventing the filter plate 504 from being blocked by impurities, thereby improving the filtering efficiency of the filter plate 504. The motor 505 is turned on during the filtering process. The rotation of the output end of the motor 505 drives the transmission rod 506 to rotate. The rotation of the transmission rod 506 drives the cam 507 to rotate. When the cam 507 contacts the buffer ring 509, the buffer ring 509 can reduce the collision force between the rotating rod 508 and the cam 507, thereby preventing the rotating rod 508 and the cam 507 from being damaged. At this time, the rotating rod 508 drives the slide tube 503 to slide upward. The sliding of the slide tube 503 drives the filter plate 504 to slide. When the cam 507 contacts the buffer ring 509, the buffer ring 509 can reduce the collision force between the rotating rod 508 and the cam 507, thereby preventing the rotating rod 508 and the cam 507 from being damaged. After the punch ring 509 is out of contact, the filter plate 504 will slide downward. Therefore, as the motor 505 continues to rotate, the filter plate 504 will slide back and forth in the vertical direction and shake, thereby accelerating the impurities to slide downward along the surface of the filter plate 504, further avoiding the accumulation of impurities on the upper end of the filter plate 504 and affecting the normal filtering of the raw materials by the filter plate 504. When the impurities need to be cleaned, the retaining ring 511 can prevent the impurities from being spilled from the surface of the filter plate 504 after the filter plate 504 is taken out of the filter box 1.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
