Description

Technical Field

[0001] The invention relates to the technical field of ball mill cylinders, and in particular to a water-cooled ball mill cylinder for preparing carbon nanotube slurry. Background Art

[0002] The ball mill cylinder is the core component of the ball mill. It is a closed and usually cylindrical metal container used to hold grinding media and materials to be ground.

[0003] In the production process of carbon nanotube slurry, when a ball mill is used to grind the carbon nanotube slurry, the carbon nanotube slurry will be pumped into the ball mill cylinder body from the feed pipe through the feed pump, and then the ball mill will be started to drive the sand grinding disc rod inside the ball mill cylinder body to rotate, so that the grinding medium and carbon nanotube slurry placed inside are stirred and ground. After grinding, the grinding medium will be filtered and discharged through the filter screen at the discharge pipe, so that the ground carbon nanotube slurry is discharged from the discharge pipe.

[0004] In this process, due to the continuous friction, impact and collision between the grinding media and the carbon nanotube particles in the carbon nanotube slurry, the mechanical energy will be converted into thermal energy, thereby increasing the temperature inside the ball mill body. Excessively high temperature may cause the structure of the carbon nanotube particles to become amorphous or graphitized, thereby affecting their original conductivity and mechanical strength, and reducing the quality of the carbon nanotube slurry. At the same time, high temperature may also reduce the hardness of the grinding media, reduce the impact and shearing effect on the carbon nanotube particles in the carbon nanotube slurry, and reduce the ball milling effect.

The water flows into the water hole, and then flows into the water inlet pipe to merge and then flows into the special-shaped guide hole in the water tank.

[0041] Reference Figure 1-12 As shown, this embodiment discloses that the outer surface of the air duct 34 is fixedly connected with a circular hole block 36, and one side of the circular hole block 36 is fixedly connected to one side of the water tank 213. By providing the circular hole block 36, the outer surface of the air duct 34 can be supported on one side of the water tank 213, so that it is not easy to shake when in use. The inner walls of several outlets of the spray rod 35 are fixedly connected with elastic protective blocks 37, and several elastic protective blocks 37 are arranged at equal distances. By providing the protective blocks, the inner walls of several outlets of the spray rod 35 can play a protective role, so that it can only blow air outward, and external dust and impurities are not easy to enter the interior when not in use, thereby reducing the possibility that the spray rod 35 is blocked and cannot be used.

[0042] The specific working process of this embodiment is: In the process of producing carbon nanotube slurry, when the carbon nanotube slurry is ground by ball mill 7, the carbon nanotube slurry is pumped into the ball mill cylinder body 1 from the feed pipe 9 through the feed pump 8, and then the ball mill 7 is started to drive the sand grinding disc rod 6 inside the ball mill cylinder body 1 to rotate, so that the grinding medium and carbon nanotube slurry placed inside are stirred and ground, and after grinding, the grinding medium is filtered out by the filter screen 5 at the discharge pipe 4, so that the ground carbon nanotube slurry is discharged from the discharge pipe 4; In the process of using the ball mill body 1 to grind the carbon nanotube slurry, the water pump 215 at the water outlet of the water tank 213 can be started to pump the cold water in the water tank 213 into the water outlet pipe 216, and then evenly dispersedly enter the first water inlet hole 24, the second water inlet hole 25 and the third water inlet hole 26 from the other end, and then the cold water is respectively injected into the several cooling cavities separated by the arc baffle 22 inside the two arc cavities 21 through the first water inlet hole 24, the second water inlet hole 25 and the third water inlet hole 26, and the cold water enters from one end of the several cooling cavities, and then the guide plate 23 is used to guide and prolong the flow speed of the cold water in the cooling cavity, so that the cold water can fully contact the inner wall of the ball mill body 1 to exchange heat, so that the area can achieve rapid cooling. The cooling effect is achieved. After the heat exchange, the cold water will flow into the first water outlet hole 27, the second water outlet hole 28 and the third water outlet hole 29 respectively, and the piston plate 212 is squeezed and impacted to slide toward one end, so that the water can be discharged and flow into the water inlet pipe 217. At this time, the spring 211 is stretched between the piston plate 212 and the connecting block 210. When the water is not drained, the spring 211 will drive the piston plate 212 to reset and block the inner wall of the first water outlet hole 27, the second water outlet hole 28 and one end of the third water outlet hole 29, so that the water in the inner wall is not easy to flow back to the arc cavity 21, and then flow into the water inlet pipe 217, merge, and then flow into the special-shaped guide hole 214 in the water tank 213, and the flow channel is extended again, so that it is fully in contact with the inner wall of the water tank 213; After the semiconductor refrigeration sheet 224 cools the surface of the water tank 213, the water flowing into the special-shaped guide hole 214 will exchange heat with the inner wall of the water tank 213 to reduce the temperature of the water. The water discharged from the outlet of the special-shaped guide hole 214 will fall on one end of the second impeller rod 219. When the water flows in the water inlet pipe 217, it will drive the first impeller rod 218 to rotate. Then, under the transmission action of the first belt 220, the second impeller rod 219 can be driven to rotate in the water tank 213, stirring the falling water to disperse it to both sides, and fully contacting with the inner wall of the water tank 213 again to achieve cooling. The stirred water will fall on the rectangular plate 223, and then fall into the bottom of the water tank 213 and be pumped out by the water pump 215. The arc-shaped cavity 21 between the outer surface and the inner wall of the ball mill body 1 is divided into a plurality of cooling cavities by the arc-shaped baffle plate 22 and the guide plate 23, and then the same amount of cold water with the same temperature is injected into each cooling cavity, so that each area can be evenly cooled, avoiding the situation in reality that the cold water rises in temperature after entering the first half for cooling, resulting in uneven cooling when cooling the second half, so that it can achieve rapid cooling and more uniform cooling, thereby improving cooling efficiency.

[0043] When the second impeller rod 219 rotates, the fan blades 32 are driven by the second belt 33 to rotate inside the air duct 31, and the external wind is drawn in from the air inlet of the air duct 31, and then blown into the air guide duct 34, and finally sprayed by two nozzles to the heat dissipation fins on one side of the two semiconductor refrigeration sheets 224, so as to blow away the dust and impurities attached to the heat dissipation fins, so as to avoid accumulation that affects the use of the semiconductor refrigeration sheets 224, and at the same time assist the semiconductor refrigeration sheets 224 in heat dissipation.
