[0002] Chromium metal etching solution is mainly used to form fine patterns on the metal surface and is often applied in the fields of electronics, microelectronics, optics, etc. Preparing chromium metal etching solution requires strict control of the proportion and sequence of various chemical components to ensure the consistency and reliability of the etching effect. The preparation of chromium metal etching solution mainly includes steps such as raw material preparation, mixing and preparation, filtration and purification, and packaging and storage. Therefore, it can be seen that the existing etching solution preparation equipment basically meets people's usage requirements, but there are still the following problems.

[0003] During the preparation of chromium metal etching solution, after the reaction is completed, it is necessary to filter and purify the product to remove impurities and unreacted substances in it to ensure the purity of the etching solution. When filtering, a filter may be used to filter the liquid after the reaction is completed. When filtering, the operator introduces the liquid into the filter through a pipeline, and then the filter element in the filter filters the reaction liquid. And when filtering, the impurities in the reaction liquid may adhere to the surface of the filter element, resulting in the blockage of the filter element. For this reason, we propose a preparation device for chromium metal etching solution. Content of the Utility Model

[0004] The utility model provides a preparation device for chromium metal etching solution. The installation plate drives the scraper to rotate on the surface of the filter element, so that the scraper scrapes the impurities attached to the surface of the filter element, avoiding the long-term accumulation of impurities on the surface of the filter element, increasing the filtering effect of the filter element, and improving the service life of the filter element.

[0005] To achieve the above object, the utility model provides the following technical solution: A preparation device for chromium metal etching solution, including a filtration tank and a filter element. The filter element is installed in the middle of the filtration tank.

[0006] Furthermore, an installation block is fixed at the end of the motor close to the rotating shaft. An installation groove opened on the rotating shaft is sleeved on the surface of the installation block.

[0021] In order to further understand the content, features and effects of the present utility model, the following embodiments are hereby cited and described in detail in conjunction with the accompanying drawings.

[0022] Embodiment:

[0023] Please refer to Figure 1 - Figure 5, A preparation device for a chromium metal etching solution, comprising a filtration tank 1 and a filter element 2. The filter element 2 is installed in the middle of the filtration tank 1. A motor 6 is installed on the outer side wall of the filtration tank 1, and a rotating shaft 4 is installed at the output end of the motor 6. A traction sleeve 7 welded to the filtration tank 1 is sleeved on one side where the output end of the motor 6 and the rotating shaft 4 are connected to each other. A fixing plate 3 is welded to the end of the rotating shaft 4, and fixing blocks 8 are welded around the fixing plate 3. Spring grooves 23 and mounting rods 29 are welded to the ends of the fixing blocks 8. A collar 11 sleeved on the surface of the filter element 2 is welded to the end of the spring groove 23. Mounting plates 9 are installed between the collar 11 and the spring groove 23. A scraper 10 that fits against the surface of the filter element 2 is welded to the surface of the mounting plate 9. When the operator guides the liquid into the filtration tank 1 through a pipeline, the liquid is filtered through the filter element 2, and the filtered liquid is discharged through the pipeline provided at the end of the filtration tank 1. During the filtration process, the operator starts the motor 6. After the motor 6 starts, the output end of the motor 6 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the mounting rod 29 to move through the fixing plate 3. When the mounting rod 29 moves, the mounting rod 29 drives the collar 11 through the mounting plate 9, causing the fixing plate 3, the mounting rod 29, the mounting plate 9, and the collar 11 to rotate on the surface of the filter element 2. When the fixing plate 3, the mounting rod 29, the mounting plate 9, and the collar 11 rotate on the surface of the filter element 2, the mounting plate 9 drives the scraper 10 to move. Since the scraper 10 fits against the surface of the filter element 2, when the mounting plate 9 drives the scraper 10 to move on the surface of the filter element 2, the scraper 10 scrapes the dirt attached to the surface of the filter element 2, preventing the dirt from adhering to the surface of the filter element 2 and causing the dirt to accumulate on the surface of the filter element 2, thereby affecting the heat dissipation efficiency of the filter element 2 and increasing the service life of the filter element 2.

[0024] In other embodiments, an installation block 18 is welded to the end of the motor 6 near the rotating shaft 4. An installation groove 20 opened on the rotating shaft 4 is sleeved on the surface of the installation block 18. Bolts 21 pass through the middle of the installation block 18 and the end of the rotating shaft 4. A threaded groove 19 opened on the inner wall of the installation groove 20 is sleeved at the end of the positioning groove 12. When the operator needs to remove the fixing plate 3, the operator first moves the bolt 21 to the notch opened on the surface of the traction sleeve 7. Subsequently, the operator passes the bolt 21 through the notch opened on the surface of the traction sleeve 7 and aligns the screwdriver with the groove provided on the surface of the bolt 21. Then the operator rotates the screwdriver, and the screwdriver drives the bolt 21 to rotate through the notch opened on the surface of the bolt 21. The bolt 21 is in threaded engagement with the threaded groove 19, causing the bolt 21 to move out of the threaded groove 19. Subsequently, the operator pulls the bolt 21, and the bolt 21 moves out of the round holes opened in the installation block 18 and the rotating shaft 4, so that the bolt 21 no longer fixes the installation groove 20 and the installation block 18. Then the operator pulls the rotating shaft 4, and the rotating shaft 4 drives the installation groove 20 to move out of the surface of the installation block 18, separating the motor 6 from the rotating shaft 4, thereby disassembling the fixing plate 3, which facilitates the operator to repair or replace the fixing plate 3 and the motor 6.

[0025] In other embodiments, on any one side of the traction sleeve 7, a first spring 16 is horizontally symmetrically welded. A positioning rod 13 passes through the middle of the first spring 16. At the ends of the positioning rod 13, positioning grooves 12 opened on the rotating shaft 4 are sleeved. On the inner walls of the first springs 16, sliding plates 15 are welded. On the surface of the sliding plates 15, sliding grooves 17 opened on the positioning rod 13 are sleeved. Through the middle of the sliding plates 15, sliding rods 14 welded to the inner walls of the sliding grooves 17 pass through. On the surfaces of the sliding rods 14, the first springs 16 are wound. The two end portions of the first spring 16 respectively abut between the inner wall of the sliding groove 17 and the surface of the sliding plate 15. At the end of the positioning rod 13, a push plate 5 is welded. A rectangular notch is opened on the traction sleeve 7 at the same position as the first spring 16. When the operator installs or disassembles the motor 6 and the rotating shaft 4, in order to facilitate the positioning of the rotating shaft 4 and the motor 6, when the operator presses the hand on the surface of the push plate 5, then the operator pushes the push plate 5. The push plate 5 pushes the positioning rod 13 to slide in the first spring 16. During the sliding process of the positioning rod 13, the positioning rod 13 drives the sliding groove 17 to move, so that the sliding groove 17 slides on the surface of the sliding plate 15. When the sliding groove 17 slides on the surface of the sliding plate 15, the sliding rod 14 fixed to the inner wall of the sliding plate 15 slides in the circular through hole opened in the middle of the sliding plate 15, so that the sliding rod 14 guides the moving track of the sliding plate 15, improving the stability of the movement of the positioning rod 13. At the same time, when the sliding groove 17 moves on the surface of the sliding plate 15, the inner wall of the sliding groove 17 squeezes the first spring 16 wound on the surface of the sliding rod 14, causing the first spring 16 to undergo elastic deformation. After the first spring 16 undergoes elastic deformation, the first spring 16 gives way to the sliding groove 17, enabling the positioning rod 13 to slide in the first spring 16, and inserting the positioning rod 13 into the positioning groove 12. By inserting the positioning rod 13 into the positioning groove 12, the rotating shaft 4 and the motor 6 are fixed in the traction sleeve 7, facilitating the operator to position the rotating shaft 4 and the motor 6.

[0026] In other embodiments, spring grooves 23 are symmetrically provided on both sides of the mounting plate 9, and second springs 22 and latches 25 are respectively provided inside the spring grooves 23, and the ends of the second springs 22 are respectively abutted between the surface of the latches 25 and the inner wall of the spring grooves 23, and the ends of the latches 25 are sleeved with pin grooves 26 respectively provided on the mounting rod 29 and the collar 11, and the surfaces of the latches 25 are welded with pull blocks 24 passing through one side of the spring grooves 23, and the surfaces of the pull blocks 24 are all provided with arc grooves, and the inner walls of the arc grooves provided on the surfaces of the pull blocks 24 are all welded with a plurality of groups of semicircular protrusions, so that when the operator needs to replace the scraper 10 The operator first places his hand in the pull block 24, and when the operator's hand and the pull block 24 fit together, the operator's hand is inserted into the arc groove set in the pull block 24, and the operator's hand and the semicircular protrusion fixed on the inner wall of the arc groove set in the pull block 24 fit together, increasing the friction force of the operator against the surface of the pull block 24, and improving the stability of the operator pulling the pull block 24 to move. After the operator pulls the pull block 24 to move, the pull block 24 pulls the latch 25 to slide in the spring groove 23, and when the latch 25 slides in the spring groove 23, the latch 25 squeezes the second spring 2 2, so that the second spring 22 is elastically deformed. After the second spring 22 is elastically deformed, the second spring 22 avoids the latch 25, so that the latch 25 enters the spring groove 23. After the latch 25 enters the spring groove 23, the latch 25 no longer fixes the mounting plate 9, the mounting rod 29 and the collar 11 through the pin groove 26. The operator pulls the mounting plate 9, and the mounting plate 9 drives the scraper 10 to move, and the mounting plate 9 and the scraper 10 are taken out from between the mounting rod 29 and the collar 11. Then the operator takes the new mounting plate 9 and stores the latch 25 in the spring groove 23. Then the operator The author takes the mounting plate 9, and the mounting plate 9 drives the scraper 10 to move, and moves the mounting plate 9 between the mounting rod 29 and the ring 11. Then the operator aligns the latch 25 with the pin groove 26. When the latch 25 and the pin groove 26 are aligned with each other, the operator releases the pull block 24. After the pull block 24 no longer squeezes the second spring 22 through the latch 25, the elastic deformation of the second spring 22 is restored, and the second spring 22 pushes the latch 25 to move, so that the latch 25 is inserted into the pin groove 26, and the mounting plate 9 is installed again between the mounting rod 29 and the ring 11, which is convenient for the operator to replace the mounting plate 9 and the scraper 10.

[0027] In other embodiments, avoidance grooves 27 are provided on the outer walls of both side ends of the mounting plate 9, and a board eaves 28 welded to the outer walls of the mounting rod 29 and the sleeve ring 11 are inserted in the middle of the avoidance grooves 27. When the operator installs the mounting plate 9 between the mounting rod 29 and the sleeve ring 11 again, the operator moves the mounting plate 9, and the mounting plate 9 drives the avoidance grooves 27 to move, so that the avoidance grooves 27 are sleeved on the surface of the board eaves 28. The board eaves 28 support the mounting plate 9 through the avoidance grooves 27, which is convenient for positioning the mounting plate 9 and convenient for the operator to install the mounting plate 9.

[0028] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
