[0027] Please refer to Figures 1-3 and Figure 6 , a ball mill with a cooling system, which comprises a ball mill cylinder 1 and a water cooling circulation system, the water cooling circulation system comprises a water cooling clamp 2 built in the ball mill cylinder 1, a circulating water pool 3, a circulating water pump 4, a cooling water inlet pipe 5 and a cooling water return pipe 6, the input end of the circulating water pump 4 extends into the circulating water pool 3, the output end of the circulating water pump 4 is communicated with the cooling water inlet pipe 5, the output end of the cooling water return pipe 6 extends into the circulating water pool 3, and a water cooling cavity is formed between the inner wall of the ball mill cylinder 1 and the outer wall of the water cooling clamp 2; further comprising a scale removal mechanism slidingly installed at the outer wall of the water cooling clamp 2, a first communication pipe 7 and a second communication pipe 8, two ends of the ball mill cylinder 1 are respectively provided with a rotary joint 9 communicated with the inside of the water cooling cavity, one end of the first communication pipe 7 and the second communication pipe 8 is respectively connected with the two rotary joints 9, the other end of the first communication pipe 7 and the second communication pipe 8 is communicated with the cooling water inlet pipe 5 and the cooling water return pipe 6, the communication position of the cooling water inlet pipe 5 and the first communication pipe 7 and the second communication pipe 8 is provided with a first valve 10 and a second valve 11, and the communication position of the cooling water return pipe 6 and the first communication pipe 7 and the second communication pipe 8 is provided with a third valve 12 and a fourth valve 13; the scale removal mechanism comprises a ring frame 14 and a plurality of water passing filter screens 15 arranged on the ring frame 14.

[0028] Please refer to Figure 3 , the two ends of the water cooling clamp 2 are both provided with a limiting ring 19. The filter hole diameter of the water passing filter screen 15 is less than 1mm.

[0029] Specifically, please refer to Figure 4 , the inner circle of the ring frame 14 is provided with a ring blade 16. The outer circle of the ring frame 14 is provided with a centralizing ring 17, and the two sides of the centralizing ring 17 are both provided with a slope blade 18; further, the width of the centralizing ring 17 is at least 5cm.

[0030] Please refer to Figure 5 The filter hole of the water filter screen 15 is less than 1 mm, so that the scraping mechanism has enough resistance to the water flow, so that the water flow in the water cooling cavity provides enough thrust to the movement of the scraping mechanism. The ring blade 16 can reduce the contact area between the ring frame 14 and the outer wall of the water cooling cylinder 2, thereby reducing the friction therebetween; the centralizing ring 17 can ensure that the ring frame 14 always remains perpendicular to the central axis of the water cooling cylinder 2 during movement, thereby avoiding the inclination of the ring frame 14 in the vertical direction, so as to ensure the stability of the horizontal movement of the ring frame 14, and the slope blade 18 can be more smoothly inserted into the scale attached to the inner wall of the ball mill cylinder 1, thereby improving the smoothness of the scraping of the ring frame 14 to the scale on the inner wall of the ball mill cylinder 1, and effectively reducing the resistance of the scale on the inner wall of the ball mill cylinder 1 to the ring frame 14.

[0031] The first communication pipe 7 and the second communication pipe 8 are both provided with a pipeline filter 20. The first valve 10, the second valve 11, the third valve 12 and the fourth valve 13 are all electric valves.

[0032] The pipeline filter 20 can trap and filter the scale scraped in the water cooling cavity, so as to avoid the backflow of the scale to the circulating water pool 3. The operator can clean the pipeline filter 20 regularly. The electric valve can be remotely controlled by an external PLC system, and the opening and closing of each valve can be set regularly according to the cleaning requirement, so that the operator does not need to operate on site, thereby improving the operation convenience. The electric valve is a conventional electromagnetic valve or other electric butterfly valve on the market, and the structure principle thereof will not be further limited and described herein.

[0033] The use process of the ball mill with a cooling system is as follows: the cold water in the circulating water pool 3 is pressurized by the circulating water pump 4, and then injected into the cooling cavity through the cooling water inlet pipe 5 and the first communication pipe 7. The circulating cooling water flows back to the circulating water pool 3 through the second communication pipe 8 and the cooling water return pipe 6, so as to realize the cooling of the material in the water cooling cylinder 2. After a period of use, the first valve 10 and the fourth valve 13 are opened, and the second valve 11 and the third valve 12 are closed, so that the circulating water enters the cooling cavity through the first communication pipe 7. There is a large amount of dirt on the water filter screen 15, and the water flow through the water filter screen 15 is limited. The water flow force of the circulating water on the scraping mechanism is greater than the friction between the scraping mechanism and the inner wall of the ball mill cylinder 1 and the outer wall of the water cooling cylinder 2, so as to drive the scraping mechanism to move in the water cooling cavity. Then, the second valve 11 and the third valve 12 are opened, and the first valve 10 and the fourth valve 13 are closed. The water flow forms a reverse thrust on the scraping mechanism, and the scraping mechanism moves horizontally in the water cooling cavity, so as to automatically scrape the scale on the outer wall of the water cooling cylinder 2 and the inner wall of the ball mill cylinder 1.
