[0022] like Figure 1-6 As shown, the present invention provides a technical solution: a wastewater treatment agent mixing device, including a mixing tank 1 and a bottom plate 2. A scraping mechanism 3 is provided inside the mixing tank 1. The scraping mechanism 3 includes a fixed sleeve 301, a connecting rod 302, a scraper 303, a guide plate 304, and a discharge pipe 305. The inner wall of the fixed sleeve 301 is fixedly connected to the outer wall of the rotating rod 404. The outer wall of the fixed sleeve 301 is fixedly connected to one end of the connecting rod 302. The other end of the connecting rod 302 is fixedly connected to one side of the scraper 303. The inner wall of the mixing tank 1 is fixedly connected to both ends of the guide plate 304. One side of the mixing tank 1 is connected to one end of the discharge pipe 305. There are three fixed sleeves 301, which are distributed sequentially on the outer wall of the rotating rod 404. One end of the scraper 303 is pressed against the inner wall of the mixing box 1. The scraper 303 is trapezoidal in shape, which can effectively scrape off the agent remaining on the inner wall of the mixing box 1 and clean it more thoroughly. The bottom of the mixing box 1 is fixedly connected to the top of the base plate 2. A movable door is installed on the front of the mixing box 1. The top of the mixing box 1 is fixedly connected to the bottom of the fixed rod 601. By setting the movable door, the residual agent inside the mixing box 1 can be scraped off and centrally processed. The operator pours the wastewater and chemicals into the mixing tank 1 through the filtration mechanism, and mixes and processes the wastewater and chemicals by starting the stirring mechanism 3. After the processing is completed, the motor 402 drives the rotating rod 404 to rotate, which in turn drives the fixed sleeve 301 to rotate, which in turn drives the connecting rod 302 to rotate, which in turn drives the scraper 303 to rotate. The scraper 303 can scrape off the residual chemicals on the inner wall of the mixing tank 1. The scraped chemicals are then guided by the guide plate 304 and discharged through the discharge pipe 305. This invention enables better scraping of the reagent inside the mixing tank 1, solving the problem that in actual use, there will be reagent residue on the inner wall of the tank during the mixing process, and it is time-consuming and laborious to directly clean the tank. This allows for more thorough cleaning and ensures better mixing results. Example 2:

[0023] Based on Example 1, such as Figure 1-6 As shown, the present invention provides a technical solution: the stirring mechanism 4 includes a mounting plate 401, a motor 402, an electric telescopic rod 403, a rotating rod 404, and a stirring blade 405. The bottom of the mounting plate 401 is fixedly connected to the top of the mixing box 1, the inner wall of the mounting plate 401 is fixedly connected to the outer wall of the motor 402, the output end of the motor 402 is fixedly connected to the top of the electric telescopic rod 403, the bottom of the electric telescopic rod 403 is fixedly connected to the top of the rotating rod 404, and the outer wall of the rotating rod 404 is fixedly connected to one end of the stirring blade 405.

The stirring blades 405 are distributed on the outer wall of the rotating rod 404, which can better mix the sewage and the agent, improve the stirring range, and drive the scraping mechanism 3 to move. After the wastewater and chemicals are poured into the mixing tank 1, the motor 402 is started to rotate, which drives the electric telescopic rod 403 to rotate. The electric telescopic rod 403 rotates, which drives the rotating rod 404 to rotate. The rotating rod 404 rotates, which drives the stirring blade 405 to rotate, thereby stirring and mixing the wastewater and chemicals. At this time, the electric telescopic rod 403 is started to move, which drives the rotating rod 404 to move, thereby moving the stirring blade 405 up and down, thereby increasing the mixing range and making the wastewater and chemicals mix more thoroughly. This technology enables better mixing of wastewater and chemicals, thereby effectively improving wastewater treatment efficiency and the working efficiency of the chemical mixing device. Example 3:

[0024] Based on Example 1, such as Figure 1-6 As shown, the present invention provides a technical solution: a buffer mechanism 5 is provided below the base plate 2. The buffer mechanism 5 includes a buffer box 501, a buffer plate 502, a buffer rod 503, a support plate 504, and a damper 505. The top of the buffer box 501 is fixedly connected to the bottom of the base plate 2. The inner wall of the buffer box 501 is slidably connected to both ends of the buffer plate 502. The bottom of the buffer plate 502 is fixedly connected to the top of the buffer rod 503. The bottom of the buffer rod 503 is fixedly connected to the top of the support plate 504. The top of the support plate 504 is fixedly connected to the bottom of the damper 505. A connecting plate 506 is fixedly installed on the top of the support plate 504. A limiting rod 507 is slidably connected to the inner wall of the connecting plate 506. A limiting plate 508 is fixedly installed on the bottom of the limiting rod 507. There are four buffer boxes 501, which are distributed in sequence at the four corners of the bottom of the base plate 2. A spring is fixedly installed between the top of the buffer plate 502 and the inner wall of the buffer box 501. The springs are symmetrically distributed on the top of the buffer plate 502, so as to provide shock absorption when vibration occurs. The connecting plate 506 is U-shaped. The top of the limiting rod 507 is fixedly connected to the bottom of the base plate 2. A spring is fixedly installed between the top of the connecting plate 506 and the bottom of the base plate 2. There are two support plates 504. The support plates 504 are symmetrically distributed at the bottom of the connecting plate 506, so as to better absorb shock and buffer, and fully protect the drug mixing device. When the drug mixing device vibrates during operation, the support plate 504 moves, causing the buffer rod 503 to move. The buffer rod 503 moves, causing the buffer plate 502 to slide on the inner wall of the buffer box 501. The sliding of the buffer plate 502 compresses the first spring. As the support plate 504 moves, the connecting plate 506 slides on the limiting rod 507 and compresses the second spring. The movement of the support plate 504 compresses the damper 505, thereby providing shock absorption and buffering, fully protecting the drug mixing device, and reducing the noise generated during operation. This technology enables vibration damping and buffering during the operation of the pharmaceutical mixing device, thereby better protecting the device, effectively increasing its service life, and reducing the inconvenience of the device. Example 4:

[0025] Based on Example 1, such as Figure 1-6 As shown, the present invention provides a technical solution: a filtration mechanism 6 is provided on both sides of the mixing box 1. The filtration mechanism 6 includes a fixing rod 601, a filter box 602, a filter screen 603, and a guide pipe 604. One end of the fixing rod 601 is fixedly connected to one side of the filter box 602. The inner wall of the filter box 602 is fixedly connected to both ends of the filter screen 603. The bottom of the filter box 602 is connected to the top of the guide pipe 604. The fixed rod 601 is L-shaped, and there are two fixed rods 601. The fixed rods 601 are symmetrically distributed on one side of the filter box 602. The guide pipe 604 is L-shaped, which can filter sewage and chemicals and filter impurities in sewage and chemicals, effectively improving the treatment effect. When it is necessary to mix sewage and chemicals, the sewage and chemicals are poured into the filter box 602 respectively. The filter screen 603 installed inside the filter box 602 can filter the impurities in the sewage and chemicals. The filtered sewage and chemicals are guided to the mixing box 1 through the guide pipe 604 installed at the bottom of the filter box 602. The filter box 602 can be supported and fixed by the fixing rod 601. It enables the filtration of wastewater and chemicals, thereby removing impurities from both, making wastewater treatment more convenient, and improving the ease of use for operators, thus enhancing the convenience of the chemical mixing device.

[0026] When using this wastewater treatment agent mixing device, the operator pours wastewater and agents into the mixing tank 1 through the filtration mechanism. The stirring mechanism 3 is then activated to mix and process the wastewater and agents. After processing, the motor 402 is activated to drive the rotating rod 404 to rotate. The rotating rod 404 drives the fixed sleeve 301 to rotate. The fixed sleeve 301 drives the connecting rod 302 to rotate. The connecting rod 302 drives the scraper 303 to rotate. The scraper 303 can scrape off the residual agents on the inner wall of the mixing tank 1. The guide plate 304 is installed to guide the flow, so that the scraped agents are discharged through the discharge pipe 305. After the wastewater and chemicals are poured into the mixing tank 1, the motor 402 is started to rotate, which drives the electric telescopic rod 403 to rotate. The electric telescopic rod 403 rotates, which drives the rotating rod 404 to rotate. The rotating rod 404 rotates, which drives the stirring blade 405 to rotate, thereby stirring and mixing the wastewater and chemicals. At this time, the electric telescopic rod 403 is started to move, which drives the rotating rod 404 to move, thereby moving the stirring blade 405 up and down, thereby increasing the mixing range and making the wastewater and chemicals mix more thoroughly. When the drug mixing device vibrates during operation, the support plate 504 moves, causing the buffer rod 503 to move. The buffer rod 503 moves, causing the buffer plate 502 to slide on the inner wall of the buffer box 501. The sliding of the buffer plate 502 compresses the first spring. As the support plate 504 moves, the connecting plate 506 slides on the limiting rod 507 and compresses the second spring. The movement of the support plate 504 compresses the damper 505, thereby providing shock absorption and buffering, fully protecting the drug mixing device, and reducing the noise generated during operation. When it is necessary to mix sewage and chemicals, the sewage and chemicals are poured into the filter box 602 respectively. The filter screen 603 installed inside the filter box 602 can filter the impurities in the sewage and chemicals. The filtered sewage and chemicals are guided to the mixing box 1 through the guide pipe 604 installed at the bottom of the filter box 602. The filter box 602 can be supported and fixed by the fixing rod 601.
