[0029] The present utility model provides an energy-saving and efficient cement mill as Figure 1 shown, including a fixed base 1, and further including:

[0030] A grinding mechanism 2, disposed on the top of the fixed base 1, for grinding and crushing materials;

[0031] A cleaning mechanism 3, disposed inside the grinding mechanism 2, for cleaning the inner wall of the grinding mechanism 2.

[0032] In order to conveniently and fully crush materials, as Figure 2 and Figure 4 shown, the grinding mechanism 2 includes a drum 201 and a rotating shaft 206. The drum 201 is disposed on one side of the top of the fixed base 1. One end of the drum 201 is provided with a feed flange 202, and the other end of the drum 201 is provided with a discharge flange 203. Fixed gear rings 205 are fixedly sleeved on the outer walls of both ends of the drum 201. The rotating shaft 206 is rotatably installed on the other side of the top of the fixed base 1. One end of the rotating shaft 206 is provided with a servo motor 207. Rotating gears 208 are fixedly sleeved on the outer sides of both ends of the rotating shaft 206. The two rotating gears 208 are respectively engaged with the two fixed gear rings 205. When the servo motor 207 operates, the rotating shaft 206 rotates. Through the meshing action between the rotating gear 208 and the fixed gear ring 205, the grinding balls inside the drum 201 can crush the materials.

[0033] In order to conveniently clean the inner wall of the drum 201, as Figure 2-5 shown, the cleaning mechanism 3 includes a transmission gear ring 301 and two mounting rods 303. The transmission gear ring 301 is fixedly installed on the inner wall of one end of the drum 201 close to the feed flange 202. The two mounting rods 303 are respectively disposed at the top and bottom inside the drum 201. Movable gears 302 are fixedly sleeved on the outer walls of one ends of the two mounting rods 303. The two movable gears 302 are engaged with the inner side of the transmission gear ring 301. Filter plates 306 are movably sleeved on the outer walls of the ends of the two mounting rods 303 away from the movable gears 302. Cleaning brushes 305 are disposed on the outer sides of the two mounting rods 303. When the drum 201 rotates, through the meshing action between the transmission gear ring 301 and the movable gear 302, the two mounting rods 303 can move on the inner wall of the drum 201, so that the cleaning brushes 305 can clean the inner wall of the drum 201.

[0034] In order to enable the drum 201 to be tightly connected to the feed flange 202 and the discharge flange 203, asFigure 2 and Figure 4 As shown, the grinding mechanism 2 includes connecting bolts 204, and two groups of connecting bolts 204 are provided, each group of connecting bolts 204 is provided with six, and the two groups of connecting bolts 204 are respectively threadedly inserted into the inner walls of the two ends of the drum 201 at equal intervals, one end of one group of connecting bolts 204 away from the drum 201 is threadedly connected to the inner wall of the feed flange 202, and the other end of the other group of connecting bolts 204 away from the drum 201 is threadedly connected to the inner wall of the discharge flange 203, and two spiral guide plates 209 are fixedly installed on the inner wall of the drum 201. The drum 201 can be conveniently connected to the feed flange 202 and the discharge flange 203 through the connecting bolts 204, so that the grinding mechanism 2 can conveniently feed and discharge.

[0035] In order to provide power for the rotation of the drum 201, Figure 4 As shown, one end of the top of the fixed base 1 is fixedly connected to the servo motor 207, and the servo motor 207 is connected to the rotating shaft 206 through an output shaft transmission. The fixed base 1 can install and fix the servo motor 207. The operation of the servo motor 207 causes the rotating shaft 206 to rotate, and through the meshing action between the rotating gear 208 and the fixed gear ring 205, the drum 201 is rotated, and then the grinding balls inside the drum 201 can grind and crush the materials.

[0036] In order to facilitate the installation and removal of the cleaning brush 305, Figure 2-3 and Figure 5 As shown, the outer walls of both ends of the mounting rod 303 are fixedly sleeved with fixed sleeves 304, the outer walls of the two fixed sleeves 304 are fixedly connected to the four adjacent cleaning brushes 305, the outer diameter of the filter plate 306 is the same as the inner diameter of the drum 201, the outer wall of the cleaning brush 305 is movably connected to the inner wall of the drum 201, and the setting of the fixed sleeve 304 makes it possible for the cleaning brush 305 to be conveniently installed on the outer side of the mounting rod 303, so that the staff can conveniently install and disassemble the cleaning mechanism 3.

[0037] The specific implementation mode is as follows: When crushing the materials used in cement production, materials can be added into the inside of the drum 201 through the feeding flange 202. Then, the rotation of the rotating shaft 206 is caused by the operation of the servo motor 207, and then the two rotating gears 208 rotate. Through the meshing action between the gear parts, the two fixed toothed rings 205 rotate, enabling the drum 201 to rotate on the top of the fixed base 1. Thus, the grinding balls inside the drum 201 can crush and grind the materials. At the same time, the spiral guide plate 209 on the inner wall of the drum 201 can guide the activities of the grinding balls and the materials, allowing the grinding balls to fully crush the materials. While the drum 201 is rotating, it can drive the transmission toothed ring 301 to rotate. Through the transmission action between the gear parts, the two movable gears 302 can move inside the transmission toothed ring 301, and at the same time, it can drive the mounting rod 303 to rotate around its own axis while revolving. Thus, the cleaning brush 305 can stably clean the inner wall of the drum 201, and at the same time, it can clean the four corner positions between the inner wall of the drum 201 and the spiral guide plate 209. At the same time, through the connection between the mounting rod 303 and the filter plate 306, the filter plate 306 also rotates at one end of the inner wall of the drum 201 close to the outlet. The materials that have been fully crushed and ground can be discharged from the inside of the drum 201 through the discharging flange 203. The setting of the spiral guide plate 209 makes the grinding and crushing of the materials more sufficient. At the same time, the cleaning mechanism 3 can clean the inner wall of the drum 201, ensuring the cleanliness of the inner wall of the drum 201. This implementation mode specifically solves the problems in the prior art that the materials cannot be fully crushed and the inner wall of the device is prone to material residue.

[0038] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
