Description

Technical Field

[0001] This utility model relates to the technical field of sand mills, and in particular to a sand mill for benzoyl oxime ester suspension. Background Technology

[0002] The main function of sand milling of ester suspension concentrates is to improve the dispersibility and stability of the agent through physical processing. The sand milling process grinds the original drug particles to the micron level (usually 1-5μm) through mechanical force, which significantly increases the specific surface area and makes the active ingredients more uniformly dispersed in the suspension system. This refinement can enhance the adhesion and coverage of the liquid on the crop leaves and reduce the sedimentation problem caused by particle agglomeration. The suspension concentrate (SC formulation) formed after sand milling can maintain the particle suspension state for a long time by adding dispersants, thickeners and other adjuvants, avoiding stratification or agglomeration. Existing technology publication number CN208390150U discloses a sand mill for preparing pyraclostrobin suspension, comprising a machine body and a base. A fixed frame is provided on the upper surface of the machine body, and a drive motor is mounted on the fixed frame. A reducer is provided at the output end of the drive motor. A dispersing shaft is located inside the machine body, and multiple dispersing discs are mounted on the dispersing shaft. The upper end of the dispersing shaft passes through the upper end of the machine body and is fixedly connected to the output end of the reducer. A feed pipe is located below the bottom end of the dispersing shaft. A discharge pipe is located on the upper right wall of the machine body. A spiral cooling pipe is located on the inner wall of the machine body, and a water outlet pipe for the cooling pipe is located on the upper right wall of the machine body. A water inlet pipe for the cooling pipe is located on the lower right wall of the machine body. The lower side of the machine body is fixedly mounted on the base. However, this method only grinds the material on the surface of the dispersing discs, failing to filter the ground material. Furthermore, due to the height of the discharge pipe, the ground material is difficult to discharge, causing it to accumulate at the bottom of the device, severely affecting the working efficiency of the sand mill. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a sand mill for benzopyrazole ester suspension that ensures cooling and circulation effects, allows qualified ground materials to be discharged in a timely manner, avoids material accumulation inside the device, ensures the grinding efficiency and working quality of the device, and improves production efficiency.

[0004] This utility model discloses a sand mill for benzoyl oxime ester suspension, comprising a grinding cylinder, a feed hopper, a rotating shaft, multiple grinding discs, a discharge pipe, a discharge valve, a cooling assembly, a filtering assembly, a cleaning assembly, and a support assembly. The feed hopper is installed at the top of the grinding cylinder. The rotating shaft is rotatably installed inside the grinding cylinder, and multiple grinding discs are mounted on the rotating shaft. The discharge pipe is installed at the bottom of the grinding cylinder, and a discharge valve is installed on the discharge pipe. The filtering assembly is installed inside the grinding cylinder, and the cooling assembly is installed at the bottom of the grinding cylinder with its output end located inside the grinding cylinder.

Material is fed into the grinding cylinder through the feed hopper and thoroughly cooled by the cooling assembly to ensure effective cooling. The filtering assembly allows for timely discharge of the ground material, preventing material accumulation inside the device and ensuring grinding efficiency and work quality, thus improving production efficiency. The cleaning assembly cleans the filtering assembly, ensuring filtration efficiency.

[0005] Preferably, the cooling assembly includes a cooling water tank, a first ring pipe, a circulating water pump, multiple cooling pipes, a second ring pipe, and a return pipe. The cooling water tank is installed at the bottom of the grinding cylinder. The first ring pipe is located inside the lower side of the grinding cylinder. The circulating water pump is installed at the front end of the outer wall of the grinding cylinder.

[0007] Preferably, it also includes a drive motor, a rotating rod, and multiple agitator rods. The drive motor is installed at the bottom of the cooling water tank, and a rotating rod is installed at the output end of the drive motor. The top output end of the rotating rod rotates through the bottom of the grinding cylinder and connects to the bottom input end of the rotating shaft. Multiple sets of agitator rods are evenly installed on the outer wall of the rotating rod. When the drive motor is started, it drives the rotating shaft to rotate through the rotating rod, so that the grinding disc completes the grinding. At the same time, the rotating rod drives the multiple sets of agitator rods to rotate, which agitates the coolant inside the cooling water tank and improves the heat dissipation effect of the coolant.

[0008] Preferably, the cleaning assembly includes multiple support rods and multiple cleaning plates. The support rods are evenly installed on the lower outer wall of the rotating shaft, and the cleaning plates are installed at the other end of the support rods.

The supporting rotating ring is rotatably installed in the rotating ring groove. Multiple push plates are evenly installed at the bottom of the supporting rotating ring. The bottom of the push plates is connected to the cleaning plate and the push plates are in contact with the inner wall of the grinding cylinder. When the cleaning plate rotates, it drives the push plates to rotate on the inner wall of the grinding cylinder, pushing the material and pushing the outer ring material towards the grinding disc, thereby improving the grinding quality. At the same time, it can scrape and clean the inner wall of the grinding cylinder.

[0010] Preferably, the support assembly includes multiple legs, a base plate, and multiple arc-shaped connecting plates.
