[0020] Reference Figure 1 , Figure 2 , Figure 3 This utility model embodiment provides a sand milling device for environmentally friendly biological pesticide suspensions, comprising: a sand milling device for environmentally friendly biological pesticide suspensions, characterized in that: a jacketed cooling cylinder 2 is fixedly connected to the outer surface of a grinding cylinder 1; a water inlet 14 is fixedly connected to the left surface of the jacketed cooling cylinder 2; a water outlet 15 is fixedly connected to the right surface of the jacketed cooling cylinder 2; a plurality of mixing spiral blades 16 are provided inside a static mixing cylinder 3; a grinding medium inlet 13 is fixedly connected to the right surface of the grinding cylinder 1; a static mixing cylinder 3 is fixedly connected to the upper surface of the grinding cylinder 1; a feed pipe 4 is fixedly connected to the upper surface of the static mixing cylinder 3; and a metering pump 17 is provided on the feed pipe 4.

[0021] Specifically, cooling water enters the space between the grinding cylinder 1 and the jacketed cooling cylinder 2 through the inlet 14, reducing the temperature of the grinding cylinder 1 to the set initial temperature. The material is then added into the feed pipe 4 and enters the static mixer 3 through the feed pipe 4. It is pre-dispersed by the mixing spiral blades 16. Then, the metering pump 17 is started, and the material is slowly fed into the grinding cylinder 1 at the set feeding rate. When the material feed reaches 60%-70% of the volume of the grinding cylinder 1, the feeding is stopped. At the same time, an appropriate amount of grinding media is added into the grinding cylinder 1 through the grinding media inlet 13 to fully mix it with the material.

[0022] Reference Figure 1 , Figure 2 , Figure 3 The stirring shaft 5 passes through the upper surface of the grinding cylinder 1. Multiple sleeves 6 are movably connected to the outer surface of the stirring shaft 5. A propeller blade 7 and a turbine blade 8 are fixedly connected to the sleeves 6. The propeller blade 7 is above the turbine blade 8.

[0023] Specifically, after stopping the feeding, the rotation speed is gradually increased. The stirring shaft 5 drives the sleeve 6 to rotate the blades. According to the material characteristics and product requirements, the rotation speed is adjusted to a suitable range. The upper propeller blades 7 push the material to form a circulating flow, and the lower turbine blades 8 rotate at high speed to generate shearing force, so that the material and grinding media are fully mixed.

[0024] Reference Figure 1 , Figure 2 , Figure 3 The cooling spiral tube 9 is fixedly connected inside the stirring shaft 5. The cooling spiral tube 9 is provided with an inlet and an outlet. A microporous filter screen 10 is provided below the stirring shaft 5. Below the microporous filter screen 10 is a discharge hopper 11. A discharge valve 18 is provided on the discharge hopper 11. A bracket 12 is fixedly connected to the lower surface of the grinding cylinder 1.

[0025] Specifically, during the grinding process, the cooling system works continuously, removing heat from the outer layer of the grinding cylinder through the jacketed cooling cylinder 2. At the same time, the coolant enters from the inlet, descends along the cooling spiral tube 9, rises again to the outlet, and passes through the stirring shaft 5 to directly cool the core grinding area, greatly improving efficiency. After grinding is completed, the discharge valve 18 is opened, allowing the material to pass through the microporous filter screen 10 to separate the grinding media, and the material is discharged from the discharge hopper 11.

[0026] Working principle: Cooling water enters the space between the grinding cylinder 1 and the jacketed cooling cylinder 2 through the inlet 14, reducing the temperature of the grinding cylinder 1 to the set initial temperature. Material is then added to the feed pipe 4 and enters the static mixer 3, where it is pre-dispersed by the mixing spiral blades 16. Then, the metering pump 17 is started, slowly feeding the material into the grinding cylinder 1 at a set feed rate. When the material feed reaches 60%-70% of the grinding cylinder 1's volume, feeding is stopped. Simultaneously, an appropriate amount of grinding media is added to the grinding cylinder 1 through the grinding media inlet 13 to ensure thorough mixing with the material. After feeding stops... The stirring shaft 5 drives the sleeve 6 to rotate the blades. The upper propeller blades 7 push the material to form a circulating flow, while the lower turbine blades 8 rotate at high speed to generate shear force, so that the material and grinding media are fully mixed. During the grinding process, the cooling system works continuously, and the jacketed cooling cylinder 2 removes the heat from the outer layer of the grinding cylinder. At the same time, the coolant enters from the inlet, descends along the cooling spiral tube 9 and then rises to the outlet to be discharged. It passes through the stirring shaft 5 and directly cools the core grinding area. After the grinding is completed, the discharge valve 18 is opened, so that the material passes through the microporous filter screen 10 to separate the grinding media, and the material is discharged from the discharge hopper 11.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
