[0030] See also Figure 1-5 The utility model provides a technical solution: a high thermal conductivity and wear-resistant material crushing and grinding device, including a crushing device shell 1, a crushing and grinding device, the crushing and grinding device is arranged inside the crushing device shell 1, the crushing and grinding device includes a first high thermal conductivity and wear-resistant material grinding block 10, the first high thermal conductivity and wear-resistant material grinding block 10 is fixedly connected to the inside of the crushing device shell 1, the surface of the first high thermal conductivity and wear-resistant material grinding block 10 is provided with a first through hole 11 and four second through holes 12, the inside of the crushing device shell 1 is fixedly connected with a fixing plate 13, the lower end of the fixing plate 13 is fixedly connected with a second driving motor 14, the output end of the second driving motor 14 is fixedly connected with a second high thermal conductivity and wear-resistant material grinding block 15, and the second high thermal conductivity and wear-resistant material grinding block 15 is rotatably connected to the fixing plate 13.

[0031] The crushing and grinding device also includes a conveying pipe 4, which is arranged on the right side of the crushing equipment housing 1. The upper end of the conveying pipe 4 is fixedly connected to the first drive motor 7, and the output end of the first drive motor 7 is fixedly connected to the transmission shaft 8. The surface of the transmission shaft 8 is fixedly connected to a high thermal conductivity and wear-resistant material conveying blade 9, and the high thermal conductivity and wear-resistant material conveying blade 9 is spiral. The end of the conveying pipe 4 close to the crushing equipment housing 1 is fixedly connected to the first connecting pipe 5 and the second connecting pipe 6, and the first connecting pipe 5 and the second connecting pipe 6 both extend to the interior of the crushing equipment housing 1.

[0032] The upper surface of the first high thermal conductivity wear-resistant material grinding block 10 is inclined toward the center, the upper end of the second high thermal conductivity wear-resistant material grinding block 15 is an arc surface, and the upper surface of the fixing plate 13 is an arc surface. The first high thermal conductivity wear-resistant material grinding block 10 and the second high thermal conductivity wear-resistant material grinding block 15 are both made of silicon carbide.

[0033] A guide frame 16 is fixedly connected to the inner wall of the pulverizing equipment housing 1, and the guide frame 16 is funnel-shaped. A third through hole 17 is opened on the bottom surface of the guide frame 16. A high thermal conductivity and wear-resistant material filter plate 18 is fixedly installed on the inner wall of the pulverizing equipment housing 1, and the high thermal conductivity and wear-resistant material filter plate 18 is inclined. A high thermal conductivity and wear-resistant material collection box 19 is fixedly connected to the bottom surface of the pulverizing equipment housing 1, and the end of the second connecting pipe 6 away from the conveying pipe 4 is fixedly connected to the high thermal conductivity and wear-resistant material collection box 19.

[0034] The upper end of the pulverizing device housing 1 is fixedly connected with a material inlet 2 , the bottom surface of the pulverizing device housing 1 is funnel-shaped, and the lower end of the pulverizing device housing 1 is fixedly connected with a material outlet 3 .

[0035] When using the device, first add the high thermal conductivity and wear-resistant material into the interior of the pulverizing equipment housing 1 from the feed port 2, and drop it to the upper end of the first high thermal conductivity and wear-resistant material grinding block 10, and then flow from the first through hole 11 and the second through hole 12 to the gap between the second high thermal conductivity and wear-resistant material grinding block 15 and the first high thermal conductivity and wear-resistant material grinding block 10, start the second drive motor 14 to drive the second high thermal conductivity and wear-resistant material grinding block 15 to rotate, and pulverize and grind the high thermal conductivity and wear-resistant material. The setting of the first through hole 11 and the second through hole 12 can increase the feeding speed of the high thermal conductivity and wear-resistant material and improve the grinding efficiency.

[0036] The ground high thermal conductivity and wear-resistant material falls into the inside of the guide frame 16. Since the upper surface of the fixed plate 13 is an arc surface, the high thermal conductivity and wear-resistant material can be prevented from gathering on the surface of the fixed plate 13. Then the high thermal conductivity and wear-resistant material is guided to the surface of the high thermal conductivity and wear-resistant material filter plate 18 through the third through hole 17 to filter the high thermal conductivity and wear-resistant material. Larger particles of high thermal conductivity and wear-resistant material flow from the surface of the high thermal conductivity and wear-resistant material filter plate 18 to the inside of the high thermal conductivity and wear-resistant material collection box 19, and smaller particles of high thermal conductivity and wear-resistant material fall to the bottom of the pulverizing equipment shell 1 and are discharged from the discharge port 3.

[0037] Since the high thermal conductivity wear-resistant material has high hardness and wear resistance, the first high thermal conductivity wear-resistant material grinding block 10 and the second high thermal conductivity wear-resistant material grinding block 15 use silicon carbide material to efficiently and quickly crush and grind the high thermal conductivity wear-resistant material. After the high thermal conductivity wear-resistant material is ground by the first high thermal conductivity wear-resistant material grinding block 10 and the second high thermal conductivity wear-resistant material grinding block 15, there may still be some larger particles of high thermal conductivity wear-resistant material. The high thermal conductivity wear-resistant material is circulated and transported through the conveying pipe 4, and the high thermal conductivity wear-resistant material is crushed and ground multiple times to improve the crushing and grinding effect of the high thermal conductivity wear-resistant material.

[0038] During the circulation of high thermal conductivity and wear-resistant materials, the first drive motor 7 is started to drive the transmission shaft 8 to rotate, and the transmission shaft 8 drives the high thermal conductivity and wear-resistant material conveying blades 9 to convey the high thermal conductivity and wear-resistant materials, and the high thermal conductivity and wear-resistant materials are conveyed from the high thermal conductivity and wear-resistant material collection box 19 through the second connecting pipe 6, the conveying pipe 4 and the first connecting pipe to the surface of the first high thermal conductivity and wear-resistant material grinding block 10 inside the crushing equipment shell 1, so as to facilitate repeated crushing and grinding of the high thermal conductivity and wear-resistant materials and improve the grinding effect of the high thermal conductivity and wear-resistant materials.

[0039] Furthermore, the high thermal conductivity wear-resistant material is ground by the first high thermal conductivity wear-resistant material grinding block 10 and the second high thermal conductivity wear-resistant material grinding block 15, and the high thermal conductivity wear-resistant material is circulated through the conveying pipe 4, so as to facilitate the sufficient crushing and grinding of the high thermal conductivity wear-resistant material. Since the high thermal conductivity wear-resistant material has high hardness and wear resistance, the first high thermal conductivity wear-resistant material grinding block 10 and the second high thermal conductivity wear-resistant material grinding block 15 use silicon carbide material to facilitate the rapid and sufficient grinding of the high thermal conductivity wear-resistant material. Compared with the existing grinding device, the crushing and grinding effect and crushing and grinding efficiency are improved.

[0040] The high thermal conductivity wear-resistant material is filtered through the high thermal conductivity wear-resistant material filter plate 18, so as to facilitate the filtering of the crushed and ground high thermal conductivity wear-resistant material, obtain purer and more uniformly sized high thermal conductivity wear-resistant material, separate larger particles of high thermal conductivity wear-resistant material, improve the separation efficiency of high thermal conductivity wear-resistant material, and facilitate repeated filtering of larger particles of high thermal conductivity wear-resistant material to improve the crushing and grinding effect of high thermal conductivity wear-resistant material.

[0041] Working principle: When using the device, first add the high thermal conductivity and wear-resistant material into the interior of the pulverizing equipment shell 1 from the feed port 2, and drop it to the upper end of the first high thermal conductivity and wear-resistant material grinding block 10, and then flow from the first through hole 11 and the second through hole 12 to the gap between the second high thermal conductivity and wear-resistant material grinding block 15 and the first high thermal conductivity and wear-resistant material grinding block 10, start the second drive motor 14 to drive the second high thermal conductivity and wear-resistant material grinding block 15 to rotate, and pulverize and grind the high thermal conductivity and wear-resistant material. The setting of the first through hole 11 and the second through hole 12 can increase the feeding speed of the high thermal conductivity and wear-resistant material and improve the grinding efficiency.

[0042] The ground high thermal conductivity and wear-resistant material falls into the inside of the guide frame 16. Since the upper surface of the fixed plate 13 is an arc surface, the high thermal conductivity and wear-resistant material can be prevented from gathering on the surface of the fixed plate 13. Then the high thermal conductivity and wear-resistant material is guided to the surface of the high thermal conductivity and wear-resistant material filter plate 18 through the third through hole 17 to filter the high thermal conductivity and wear-resistant material. Larger particles of high thermal conductivity and wear-resistant material flow from the surface of the high thermal conductivity and wear-resistant material filter plate 18 to the inside of the high thermal conductivity and wear-resistant material collection box 19, and smaller particles of high thermal conductivity and wear-resistant material fall to the bottom of the pulverizing equipment shell 1 and are discharged from the discharge port 3.

[0043] Since the high thermal conductivity wear-resistant material has high hardness and wear resistance, the first high thermal conductivity wear-resistant material grinding block 10 and the second high thermal conductivity wear-resistant material grinding block 15 use silicon carbide material to efficiently and quickly crush and grind the high thermal conductivity wear-resistant material. After the high thermal conductivity wear-resistant material is ground by the first high thermal conductivity wear-resistant material grinding block 10 and the second high thermal conductivity wear-resistant material grinding block 15, there may still be some larger particles of high thermal conductivity wear-resistant material. The high thermal conductivity wear-resistant material is circulated and transported through the conveying pipe 4, and the high thermal conductivity wear-resistant material is crushed and ground multiple times to improve the crushing and grinding effect of the high thermal conductivity wear-resistant material.

[0044] During the circulation of high thermal conductivity and wear-resistant materials, the first drive motor 7 is started to drive the transmission shaft 8 to rotate, and the transmission shaft 8 drives the high thermal conductivity and wear-resistant material conveying blades 9 to convey the high thermal conductivity and wear-resistant materials, and the high thermal conductivity and wear-resistant materials are conveyed from the high thermal conductivity and wear-resistant material collection box 19 through the second connecting pipe 6, the conveying pipe 4 and the first connecting pipe to the surface of the first high thermal conductivity and wear-resistant material grinding block 10 inside the crushing equipment shell 1, so as to facilitate repeated crushing and grinding of the high thermal conductivity and wear-resistant materials and improve the grinding effect of the high thermal conductivity and wear-resistant materials.

[0045] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
