[0033] like Figure 1-Figure 8 As shown, the collecting mechanism includes a collecting ring 14, a mounting seat 15 and a second mounting groove 19. The collecting ring 14 and the second mounting groove 19 are both arranged at one end of the grinding cylinder 1 close to the partition plate 16. A second circulating wheel 191 is arranged in the second mounting groove 19. The mounting seat 15 is arranged at the end of the grinding cylinder 1 away from the partition plate 16. A first circulating wheel 151, a first mounting groove 152 and a collecting motor 154 are arranged in the mounting seat 15. The first circulating wheel 151 is arranged in the first mounting groove 152. The collecting motor 154 is connected to the first circulating wheel 151 through a bevel gear assembly 155. The first circulating wheel 151 and the second circulating wheel 191 are connected through a circulating belt 153. The side end of the collecting ring 14 is fixedly mounted on the circulating belt 153.

[0034] Before the present invention is put into operation, the staff needs to place a plurality of groups of steel balls in the first working chamber 17 and the second working chamber 18. During operation, the material is transported into the grinding cylinder 1 through the feeding device 2, wherein the material first passes through the first working chamber 17. When the material is ground to a corresponding particle size, the material passes through the partition plate 16 and enters the second working chamber 18 for secondary grinding. When the material is completely ground, the staff drives the first discharge hole and the second discharge hole on the grinding cylinder 1 toward the ground through the power device 4, and then opens the first sealing cover 11 and the second sealing cover 12 to make the grinding cylinder 1 The refined materials are discharged from the grinding cylinder 1. Compared with the existing cement mill, the present invention is provided with two sets of aggregate mechanisms. After the materials are discharged, some of the materials will adhere to the inner wall of the grinding cylinder 1. At this time, the staff only needs to turn on the aggregate motor 154 inside the first working chamber 17 and the second working chamber 18 to make a set of aggregate rings 14 in the first working chamber 17 and a set of aggregate rings 14 in the second working chamber 18 move horizontally. The materials adhered to the inner wall of the grinding cylinder 1 are cleaned by the two sets of aggregate rings 14, so as to facilitate the staff to recycle these waste materials.

[0035] like Figure 1-Figure 2 , Figure 8 As shown, a plurality of groups of lining plates 13 are arranged on the inner wall of the grinding cylinder 1. The present invention protects the inner wall of the grinding cylinder 1 by means of a plurality of groups of lining plates 13. A gap is arranged between every two groups of lining plates 13. A plurality of groups of protrusions are arranged on the outer side of the collecting ring 14. The protrusions and the circulating belt 153 are arranged in the gap. Through the above technical scheme, on the one hand, it is ensured that the lining plates 13 have enough space during thermal expansion to prevent the lining plates 13 from deformation and damage. On the other hand, it is prevented that the circulating belt 153 is hit by the steel ball to ensure the service life of the collecting mechanism.

[0036] like Figure 9-10 As shown, the inside of the collecting ring 14 is provided with a plurality of groups of gas storage tanks 141, and a group of rubber pads 142 are provided at one end of each group of gas storage tanks 141 close to the inner wall of the grinding cylinder 1, and a group of first electromagnets 143 are provided at both ends of the inside of each group of gas storage tanks 141, and a group of pressing plates 144 are provided at the ends close to each other of the two groups of first electromagnets 143, and compressed gas is provided between the two groups of pressing plates 144, and a group of magnetic blocks are inlaid on each group of pressing plates 144. When the collecting mechanism of the present invention is working, the first electromagnets in each group of gas storage tanks 141 are pressed by the pressure plate 144, and the pressure plate 144 is pressed by the pressure plate 144. The magnets 143 will generate a magnetic field that repels the magnetic blocks. At this time, the two groups of pressure plates 144 in each group of air storage tanks 141 will approach each other to squeeze the compressed gas in the air storage tanks 141. Under the action of the air pressure, several groups of rubber pads 142 will be deformed and then tightly attached to the inner wall of the grinding cylinder 1. Through the above technical solution, on the one hand, it is ensured that the materials on the inner wall of the grinding cylinder 1 can be cleaned, and on the other hand, it is prevented that the outer wall of the gathering ring 14 cannot contact the inner wall of the grinding cylinder 1 due to wear, thereby preventing the waste from being discharged from the grinding cylinder 1.

[0037] like Figure 11-13 As shown, an air inlet 75 is provided at the side end of the dust exhaust box 7, and the air inlet 75 is communicated with the second hollow shaft. An air outlet 74 is provided at the lower end of the dust exhaust box 7. A fixing frame 71, a turntable 72 and a reversing motor 76 are provided inside the dust exhaust box 7. The fixing frame 71 is fixedly installed above the side end of the air inlet 75. The reversing motor 76 is arranged at one end of the dust exhaust box 7 away from the air inlet 75. The turntable 72 is arranged between the air inlet 75 and the reversing motor 76. The working end of the reversing motor 76 is connected to the turntable 72. Four groups of exhaust holes 721 are provided inside the turntable 72, and a filter assembly is provided in each group of exhaust holes 721.

[0038] When the present invention is working, the staff needs to transport gas into the grinding cylinder 1, on the one hand to dissipate heat for the cement mill, and on the other hand to take away the fine particles generated in the material grinding process, so that the contact between the grinding medium and the material is more complete. After the gas comes out of the grinding cylinder 1, it will enter the turntable 72 along the air inlet 75, and then flow out along a group of exhaust holes 721 at the lower end of the turntable 72 and the exhaust holes 721 at the left and right ends of the turntable 72. The dust in the gas is trapped by the filter components arranged in the exhaust holes 721. When the staff needs to clean the filter components in a group of exhaust holes 721, they only need to turn on the reversing motor 76 to control the rotation of the turntable 72. When the filter components to be cleaned move to the top of the fixed frame 71, the staff can clean a group of filter components on the basis of continuous ventilation.

[0039] like Figure 11-13 As shown, the filter assembly includes a mounting frame 723 and a dust removal cloth 724. The mounting frame 723 is movably mounted in the exhaust hole 721 through a compression spring rod. A through hole is provided on the mounting frame 723, and the dust removal cloth 724 is provided in the through hole.

[0040] like Figure 11-13 As shown, a groove is provided on the fixing frame 71, and a dust collecting plate 73 is provided in the groove.

[0042] When cleaning the filter assembly located above the fixing frame 71, the present invention only needs to turn on the corresponding second electromagnet 722, and control the mounting frame 723 to vibrate up and down in the exhaust hole 721 through the second electromagnet 722. When the mounting frame 723 vibrates, the dust trapped on the dust removal cloth 724 will fall into the dust collecting plate 73, so as to facilitate the subsequent reuse of the filter assembly above the fixing frame 71.

[0043] The working principle of the present invention is as follows: before operation, several groups of steel balls are placed in the first working chamber 17 and the second working chamber 18. During operation, materials are transported into the grinding cylinder 1 through the feeding device 2, and ventilation is performed into the grinding cylinder 1 through the external air pump. The materials are first ground in the first working chamber 17, and then secondly ground in the second working chamber 18. The cement mill is cooled by ventilation into the grinding cylinder 1. After the gas comes out of the grinding cylinder 1, it enters the turntable 72 along the air inlet 75, and then flows out along a group of exhaust holes 721 at the lower end of the turntable 72 and the exhaust holes 721 at the left and right ends of the turntable 72, and then flows out through the exhaust The filter assembly arranged in the hole 721 retains dust in the gas. When the material is ground, the first discharge hole and the second discharge hole on the grinding cylinder 1 are driven toward the ground by the power device 4, and then the first sealing cover 11 and the second sealing cover 12 are opened to discharge the grounded material from the grinding cylinder 1. After the material is discharged, the staff turns on the collecting motor 154 in the first working chamber 17 and the second working chamber 18 to make the collecting ring 14 in the first working chamber 17 and the collecting ring 14 in the second working chamber 18 move horizontally, and the material attached to the inner wall of the grinding cylinder 1 is cleaned by the two groups of collecting rings 14.

[0044] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. The embodiments should therefore be considered exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
