[0004] However, the above utility model patent has the following technical problems in actual use:

[0005] 1. When the stirring scraper rod of the above device rotates, it can only scrape off the slurry remaining on the inner wall of the bottom of the slurry mixing tank. Moreover, since the above device lacks a driving device for controlling the lifting and lowering of the stirring scraper rod, the height position of the stirring scraper rod cannot be adjusted, and the slurry remaining in other positions cannot be scraped off, which affects the actual use of the above device.

[0006] 2. In addition, when disassembling the No. 1 stirring rod and the No. 2 stirring rod in the above-mentioned device, it is necessary to dismantle more parts in the above-mentioned device, which greatly increases the manual labor. At the same time, it is not convenient to manually take out the No. 1 stirring rod and the No. 2 stirring rod from the slurry mixing tank during disassembly, and it also increases the workload for subsequent assembly. Utility Model Content

[0007] The utility model provides a slurry mixing device for polishing liquid production, aiming to solve the problem mentioned in the above-mentioned background technology that the height of the stirring scraper rod cannot be adjusted in the above-mentioned device, thereby failing to scrape away the slurry remaining at various positions on the inner wall of the slurry mixing tank, and at the same time, the above-mentioned device is more complicated when disassembling the No. 1 stirring rod and the No. 2 stirring rod, which affects the manual rapid disassembly and subsequent assembly.

[0008] The utility model is implemented in this way. A slurry mixing device for polishing liquid production comprises: a reaction tank, a side wall of which is connected with a feed pipe, and a bottom wall of which is connected with at least one discharge pipe, a discharge valve is fixedly installed on the discharge pipe, a stirring mechanism, which comprises: a rotating component arranged at the bottom of the reaction tank, and a plurality of stirring components detachably connected to the rotating component, wherein the plurality of stirring components are distributed at equal angles on the outside of the rotating component, and a wall scraping component which is movably installed on the top wall of the reaction tank and movably connected to the rotating component, and the wall scraping component is used to remove the residual material from the liquid. The component is used to scrape off the residual attachments on the inner wall of the reaction tank; in this scheme, the sleeve can be driven to move up and down in the vertical direction through the extension and retraction of the output end of the electric push rod, and the lifting and lowering of the sleeve drives the scraper plate fixed on its outer wall to move up and down, so as to achieve the purpose of scraping off the residual attachments at different heights on the inner wall of the reaction tank. At the same time, since the sleeve and the rotating shaft are engaged with each other through the limit groove and the limit strip, when the rotating shaft rotates, it will drive the sleeve to rotate, thereby driving the scraper plate to rotate around the inner wall of the reaction tank to achieve surrounding scraping.

[0009] In addition, the device ensures that the protruding rod is stably fixed in the trough through the threaded connection between the internal thread and the external thread, thereby ensuring stable assembly between the stirring shaft and the mounting seat.

[0013] Preferably, the scraper assembly comprises: two support plates symmetrically fixedly mounted on the top wall of the reaction tank, a horizontal plate fixedly connected horizontally between the top ends of the two support plates, an electric push rod fixedly connected to the horizontal plate, a through hole corresponding to the rotating shaft is opened on the top wall of the reaction tank, a sleeve is passed through the through hole, the sleeve is sleeved on the outer side of the rotating shaft through a slot hole on its bottom wall, and the output end of the electric push rod is rotatably connected to the top end of the sleeve, at least one scraper plate is fixedly connected horizontally to the bottom outer wall of the sleeve, and one end of the scraper plate away from the sleeve is attached to the inner wall of the reaction tank; in this scheme, when the output end of the electric push rod is extended and retracted, it will pull the sleeve to move up and down, thereby controlling the sleeve and the scraper plate on its outer wall to move longitudinally inside the reaction tank, and because the sleeve is consistent with the rotation direction of the rotating shaft through the cooperation between the limit bar and the limit groove, the sleeve will also rotate while moving up and down, so that the scraper plate is used to scrape off the attachments on the inner wall of the reaction tank.

[0014] Preferably, a plurality of limit strips are distributed at equal angles along the height of the outer wall of the rotating shaft, and a limit groove is provided on the inner wall of the slot corresponding to the plurality of limit strips, and the limit strip is inserted into the limit groove; in this scheme, by setting a snap-fit ​​fit between the limit strip and the limit groove, it can ensure that the kinetic energy of the rotating shaft is stably transmitted to the sleeve during rotation, preventing the sleeve from not rotating with the rotating shaft, and also preventing the scraper plate from colliding with the stirring shaft.

[0016] 1. Through the extension and retraction of the output end of the electric push rod, the sleeve can be driven to move up and down in the vertical direction, and the lifting and lowering of the sleeve drives the scraper plate fixed on its outer wall to move up and down, so as to achieve the purpose of scraping off the residual attachments at different heights on the inner wall of the reaction tank. At the same time, since the sleeve and the rotating shaft are engaged with each other through the limit groove and the limit strip, when the rotating shaft rotates, the sleeve will be driven to rotate, thereby driving the scraper plate to rotate around the inner wall of the reaction tank to achieve surrounding scraping.

[0017] 2. This device ensures that the protruding rod is stably fixed in the sink through the screw connection between the internal thread and the external thread, thereby ensuring the stable assembly between the stirring shaft and the mounting seat. At the same time, the threaded connection method also facilitates the subsequent rapid disassembly of the stirring shaft for cleaning, without the need to manually disassemble too many working components, thereby reducing manual workload.
