Description

Technical Field

[0001] This utility model relates to the field of sand mill technology, and specifically to an anti-clogging sand mill equipped with a cooling structure. Background Technology

[0002] A sand mill is a piece of equipment used for grinding materials. It has the advantages of high production efficiency, strong continuity, low cost, and high product fineness. According to its performance, it can be roughly divided into horizontal sand mills, basket sand mills, vertical sand mills, etc. With the diversification of sand mills, there are more and more types of sand mills, and their functions are becoming more and more perfect, which greatly improves production efficiency.

[0003] However, during the use of a sand mill, the friction between the grinding media and the material generates a large amount of heat, which causes the sand mill to overheat. In order to extend the service life of the sand mill, prevent damage to its main shaft and other equipment, and prevent the decomposition of effective components in the material at high temperatures, the sand mill generally needs to be cooled. For example, the utility model patent with publication number CN220836000U discloses an anti-clogging coating sand mill with a cooling structure, including a housing, a motor, and a circulating pump. Shock-absorbing wheels are fixedly installed at the four corners of the lower surface of the housing. Hinges are installed on the right side of the housing and the top plate. A handle is installed on the surface of the housing door. A base is installed below the sand mill body. A liquid inlet is opened on the right side of the feed hopper. A filter screen is installed inside the conveying trough. An electric telescopic rod is installed on the left side of the water tank. A collection box is installed on the right side of the circulating pump.

[0004] The aforementioned prior art allows cooling water to circulate between the water tank and the sand mill via a circulating pump, thereby cooling the sand mill. However, as the cooling process continues, the cooling water in the water tank gradually heats up. This increased temperature leads to poor cooling efficiency when the cooling water is used to cool the sand mill, thus affecting the working efficiency of the sand mill. Utility Model Content

[0054] Reference Figures 1-3 The cooling mechanism includes a water tank 7, a jacket 8, a heat dissipation mechanism, a water pump 9, a first return pipe 10, and a second return pipe 11. The water tank 7 is fixedly mounted on the sand mill body 1 and is filled with cooling water. The side wall of the grinding cylinder 2 is provided with a jacket 8. The heat dissipation mechanism is mounted on the water tank 7 and is used to dissipate heat from the cooling water. The water pump 9 is fixedly mounted on the sand mill body 1. The input end of the water pump 9 is connected to the water tank 7, and the output end of the water pump 9 is connected to the jacket 8. The first return pipe 10 is connected between the heat dissipation mechanism and the jacket 8, and the second return pipe 11 is connected between the water tank 7 and the heat dissipation mechanism.

[0055] Specifically, during the use of the sand mill body 1, the operator controls the water pump 9 to work. The operation of the water pump 9 causes the cooling water to circulate in the water tank 7 and the jacket 8. At the same time, during the cooling water circulation, heat exchange can be achieved between the grinding cylinder 2 and the cooling water through the side wall of the jacket 8, thereby facilitating the cooling of the grinding cylinder 2.

[0056] Reference Figure 3 and Figure 4The heat dissipation mechanism includes a heat dissipation shell 12, an inlet shell 13, an outlet shell 14, and a heat dissipation assembly. The heat dissipation shell 12 is fixedly mounted on the water tank 7. The inlet shell 13 and the outlet shell 14 are respectively fixedly mounted on two opposite side walls of the heat dissipation shell 12. A first return pipe 10 is connected between the inlet shell 13 and the jacket 8, and a second return pipe 11 is connected between the outlet shell 14 and the water tank 7. The heat dissipation assembly is installed inside the heat dissipation shell 12 and is used to cool the cooling water.

Multiple heat conduction pipes 15 are fixedly installed inside the heat dissipation shell 12, and the two ends of the heat conduction pipes 15 are respectively connected to the inlet shell. A connecting pipe is provided between the body 13 and the water outlet shell 14. An air circulation mechanism is provided on the heat dissipation shell 12 to control the air circulation between the heat dissipation shell 12 and the external environment. The air circulation mechanism includes a fan 16 and an air outlet 17. The fan 16 is fixedly installed on the heat dissipation shell 12.

[0059] Specifically, the operation of the first motor can control the lever 3 to rotate, and at the same time, the lever 3 can control the sand grinding disc 4 to rotate. During the rotation of the sand grinding disc 4, the cleaning rod 18 can move around the filter cover 5, and then the cleaning bristles on the cleaning rod 18 can clean the filter cover 5, thereby preventing the filter cover 5 from becoming clogged.

[0060] In this embodiment, during use, the operator controls the first motor to operate, which in turn controls the rotation of the lever 3. Simultaneously, the rotation of the lever 3 controls the rotation of the grinding disc 4, which in turn drives the grinding media to grind the material. Simultaneously, the rotation of the grinding disc 4 also drives the cleaning rod 18 to move around the filter cover 5, thereby cleaning the filter cover 5 with the cleaning bristles on the cleaning rod 18, thus preventing clogging. At the same time, the operator controls the water pump 9 to operate, which cools the material... Cooling water circulates within the water tank 7 and the jacket 8. During the cooling water circulation, heat exchange occurs between the grinding cylinder 2 and the cooling water through the side wall of the jacket 8, facilitating the cooling of the grinding cylinder 2. During the cooling process, the operator controls the fan 16 to operate, allowing air circulation between the heat dissipation shell 12 and the external environment. Simultaneously, during the cooling water return process, it flows through the heat pipe 15, enabling heat exchange between the cooling water and the airflow, thereby cooling the cooling water and improving the cooling efficiency of the grinding cylinder 2.

[0061] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
