[0002] The horizontal sand mill is one of the wet grinding equipment that can achieve the best grinding fineness. It can process a large amount of paint per unit time and is also a commonly used sand mill in the paint industry. It mainly uses the stirring shaft to drive the relative movement of the grinding media in the grinding cylinder to generate a strong shear force, so that the material can be fully ground under the action of force, thereby achieving the refinement of the solid components in the paint.

[0003] Publication No. CN203044094U discloses a horizontal sand mill for coatings, the sand mill comprises a frame and a grinding cylinder with a grinding chamber arranged at the upper end of the frame, a cooling chamber is arranged in the side wall of the grinding cylinder, a water inlet and a water outlet are arranged on the outer surface of the grinding cylinder, a stirring shaft coaxial with the grinding cylinder is arranged in the grinding chamber, one end of the stirring shaft is connected to the motor through a transmission device, a plurality of stirring teeth are arranged on the outer surface of the stirring shaft and the inner surface of the grinding cylinder respectively, a feed port and a discharge port are arranged at both ends of the grinding cylinder, and the sand mill also includes a coating temperature cooling water flow control device. Although this type of sand mill avoids the phenomenon that the material temperature rises rapidly and affects the coating quality, it ensures the processing efficiency of the sand mill. However, this type of sand mill lacks an effective water source filtering device, which easily causes large particles of impurities and foreign matter to enter the cooling pipe, causing the cooling pipe to be blocked and damaged, affecting the cooling effect and shortening the service life of the cooling pipe. Therefore, it is necessary to improve. Utility Model Content

[0011] Preferably, the heat dissipation fins are in close contact with the cooling tubes.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. The utility model can effectively take away the heat of the grinding cylinder by introducing cooling water into the cooling pipe, ensure temperature control during the grinding process, and avoid affecting the grinding effect and product quality due to excessive temperature. The filter screen is arranged to filter the water source entering the cooling pipe, prevent large particles of impurities and foreign matter from entering the cooling pipe, reduce the possibility of blockage and damage, and thus extend the service life of the cooling pipe.

The heat dissipation fins not only transfer the heat to the cooling pipe by conduction, but also dissipate the heat by convection with the air, thereby further enhancing the heat dissipation effect and ensuring that the grinding cylinder maintains a suitable temperature during the efficient grinding process. At the same time, the contact design between the heat dissipation fins and the cooling pipe makes the overall heat exchange efficiency of the cooling system higher, quickly reduces the temperature of the grinding cylinder, and avoids the adverse effects of excessive temperature on the grinding process and product quality. At the same time, since the heat dissipation fins improve the cooling effect, the cooling system can more effectively utilize cooling water, reduce the consumption of cooling water, improve resource utilization, and reduce operating costs.
