For optimal grinding results and to minimize contamination, it is generally recommended to use grinding balls made of the same cemented carbide material.

[0003] During grinding and sample preparation, the frequent and intense collisions, friction, and shearing between the grinding balls and the material and the container wall convert a large amount of mechanical energy into heat energy. Cooling the grinding container is typically achieved using heat dissipation fins, but this method is not ideal and is inefficient. Utility Model Content

The rotation of the rotating shaft and rotating blades blows air onto the heat dissipation fins, which accelerates the heat dissipation effect of the heat dissipation fins and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an alloy grinding sample preparation device with good heat dissipation and cooling, comprising a grinding jar and a top cover connected to the top of the grinding jar.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 5 This utility model provides an alloy grinding sample preparation device with good heat dissipation and cooling, including a grinding tank 1 and a top cover 2 connected to the top of the grinding tank 1. Heat dissipation fins 4 are connected to the outer side of the grinding tank 1. There are four sets of heat dissipation fins 4, arranged in pairs opposite each other, which is beneficial for heat dissipation of the grinding tank 1. A water flow channel 16 is provided in the internal interlayer of the grinding tank 1. The water flow channel 16 is connected to a heat exchange mechanism, which includes a cooling device 8, a circulating water pump 9, a liquid delivery pipe 6, and a return water pipe 10. The output end of the cooling device 8 is connected to the input end of the circulating water pump 9, and the output end of the circulating water pump 9 is connected to the liquid delivery pipe 6. The end of the liquid delivery pipe 6 is connected to the water flow channel 16, and the discharge end of the water flow channel 16 is connected to the return water pipe 10. The return water pipe 10 is connected to the input end of the cooling device 8. A blower mechanism for blowing air onto the heat dissipation fins 4 is connected to the liquid delivery pipe 6.

[0021] The grinding jar 1 is equipped with heat dissipation fins 4, which provide initial heat dissipation and facilitate cooling. When the temperature is too high, the circulating water pump 9 delivers water cooled by the cooling equipment 8 to the water flow channel 16, facilitating heat exchange in the grinding jar 1 and achieving good cooling. After heat exchange, the water is returned to the cooling equipment 8 through the return water pipe 10 for further cooling, realizing water circulation and improving the heat dissipation efficiency of the grinding jar 1, making it highly practical.

[0022] Cooling equipment 8 is existing technology, usually a cooler, used for cooling water.

[0023] The bottom of the grinding tank 1 is connected to a base 3, and the infusion pipe 6 passes through the base 3. The base 3 provides support for the grinding tank 1 and at the same time limits and fixes the infusion pipe 6.

[0024] The heat exchange mechanism also includes a connecting pipe 7, a water inlet 17, and a water outlet 14. The connecting pipe 7 is connected to the liquid delivery pipe 6. The water inlet 17 is fixed to the outside of the grinding tank 1 and is connected to the water flow channel 16. The end of the liquid delivery pipe 6 is connected to the water inlet 17. The water outlet 14 is connected to the discharge end of the water flow channel 16. The two ends of the return water pipe 10 are connected to the water outlet 14 and the cooling equipment 8.

[0025] Both ends of the connecting pipe 7 are connected to the output end of the circulating water pump 9 and the end of the infusion pipe 6.

[0026] The blower mechanism includes a sealing interface 11, a rotating shaft 12, rotating blades 13, and a spiral blade 15. Both ends of the rotating shaft 12 are connected to the rotating blades 13 and the spiral blades 15. The rotating blades 13 face the heat dissipation fins 4, and the spiral blades 15 are located inside the infusion pipe 6. The rotating shaft 12 passes through the sealing interface 11. During water delivery, the water flow direction is... Figure 3 As indicated by the middle arrow, when the water flow impacts the spiral blade 15, the momentum of the water changes, thereby applying a force to the blade. This force generates a torque relative to the rotating shaft 12, which in turn drives the rotating shaft 12 and the rotating blade 13 to rotate, thus achieving the blowing operation on the heat dissipation fins 4 and accelerating the heat dissipation effect of the heat dissipation fins 4.

[0027] The spiral blade 15 adopts a spiral structure, which ensures that at any time, part of the blade surface is in the optimal position to be impacted by the water flow, making the torque output more stable and continuous.

[0028] The sealing interface 11 is connected to the infusion pipeline 6, and the rotating shaft 12 is rotatably sealed to the sealing interface 11 to improve the sealing performance of the connection and prevent water leakage.

[0029] A control box 5 is connected to the outside of the grinding jar 1. A temperature sensor and a PLC controller are connected inside the control box 5. The temperature sensor is electrically connected to the PLC controller, which in turn is electrically connected to the circulating water pump 9. The temperature sensor is attached to the grinding jar 1. The temperature sensor detects the temperature of the grinding jar 1 and transmits the information to the PLC controller for processing. The PLC controller controls the operation of the circulating water pump 9. When the temperature is too high, the speed of the circulating water pump 9 increases, thereby increasing the water flow rate in the water channel 16 and improving the heat dissipation efficiency of the grinding jar 1. This design is highly practical.

[0030] The jacketed area of ​​grinding jar 1 is Figure 5 In section A, the water flow channel 16 is arranged in an S-shape, while the bottom of the grinding tank 1 is section B, where the water flow channel 16 is arranged in a spiral shape. This achieves a more comprehensive cooling treatment of the grinding tank 1 and effectively avoids heat accumulation at the bottom of the grinding tank 1.

[0031] The temperature sensor is model PT100, and the circulating water pump 9 is model ISG / ISW.

[0032] Working Principle: During grinding, the temperature inside the grinding jar 1 rises. The heat dissipation fins 4 facilitate cooling of the grinding jar 1. When the temperature becomes too high, the circulating water pump 9 delivers cold water from the cooling equipment 8 through the connecting pipe 7 and the liquid delivery pipe 6 to the water flow channel 16, thereby improving the heat exchange effect and achieving rapid cooling of the grinding jar 1. After heat exchange, the water is then delivered to the cooling equipment 8 through the return water pipe 10 for further cooling, and then pumped back by the circulating water pump 9 to achieve water circulation cooling. During water transport, the water flow impacts the spiral blades 15, which in turn drives the rotating shaft 12 and the rotating blades 13 to rotate, achieving airflow to the heat dissipation fins 4 and accelerating the heat dissipation effect of the heat dissipation fins 4, making it highly practical.
