Description

Technical Field

[0001] This utility model belongs to the field of cement production technology, and in particular relates to a grinding mill for cement production and preparation. Background Technology

[0002] Cement production mills are key equipment used for grinding cement clinker and other building materials. They mainly consist of separators, grinding rollers, grinding discs, pressurizing devices, reducers, motors, and housings.

[0003] Existing cement production mills are prone to clogging at the feed inlet. Due to the presence of moisture in the material during production, too much material may enter at once, causing it to adhere to the inner wall of the feed pipe. This not only affects the material feed and reduces the mill's grinding efficiency, but also requires workers to stop the mill and clean the feed pipe when the clogging is severe. Therefore, we have proposed a new type of cement production mill. Utility Model Content

[0004] The purpose of this invention is to provide a grinding mill for cement production. By incorporating a movable rod, specifically, during the rotation of the grinding roller, a fixed rod drives an arc-shaped plate to rotate together. When the arc-shaped plate contacts the ball head, it pushes the ball head, causing the movable rod to move a cleaning rod. The cleaning rod clears the feed pipe. After the arc-shaped plate leaves the ball head, the movable rod returns to its original position under the action of a spring. This repetitive motion continuously clears the feed pipe, reducing blockages and improving the mill's efficiency. This invention solves the problem of blockages easily occurring at the feed inlet of existing mills. Because the material contains a certain amount of moisture during production, excessive material may enter at once, causing it to adhere to the inner wall of the feed pipe, affecting material feeding and reducing the mill's grinding efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 As shown, this utility model is a mill for cement production and preparation, including a mill shell 1, a base 11 fixedly connected to the bottom of the mill shell 1, a cover plate 12 fixedly connected to the top of the mill shell 1 by bolts, a feed pipe 13 fixedly connected to the right side of the mill shell 1, and a grinding assembly 14 arranged inside the mill shell 1. The grinding assembly 14 includes a grinding roller 141, a fixing rod 411 fixedly connected to the top of the grinding roller 141, and an arc plate 412 fixedly connected to the outside of the fixing rod 411.

[0028] A fixed frame 131 is fixedly connected to the inner wall of the feed pipe 13. A movable rod 132 is slidably connected to the center of the fixed frame 131. A ball head 321 is fixedly connected to the left side of the movable rod 132. Several cleaning rods 322 are fixedly connected to the outer surface of the movable rod 132. A fixed shell 133 is fixedly connected to the right side of the fixed frame 131. A spring 134 is installed inside the fixed shell 133. A push ring 323 is slidably connected to the inner wall of the fixed shell 133. The inner side of the push ring 323 is fixedly connected to the outer surface of the movable rod 132. By setting the movable rod 132, the specific... During the rotation of the grinding roller 141, the fixed rod 411 drives the arc plate 412 to rotate together. When the arc plate 412 contacts the ball head 321, it pushes the ball head 321, and the movable rod 132 drives the cleaning rod 322 to move. The cleaning rod 322 clears the inside of the feed pipe 13. After the arc plate 412 leaves the ball head 321, the movable rod 132 is reset by the action of the spring 134. This process can continuously clear the feed pipe 13, reduce the occurrence of blockages, and thus improve the efficiency of the mill.

[0029] Both the right side of the fixed shell 133 and the right side of the movable rod 132 are tapered. The movable rod 132 passes through the fixed shell 133 and extends to the outside. The ball head 321 is spherical. The left side of the spring 134 is fixedly connected to the right side of the push ring 323, and the right side of the spring 134 is fixedly connected to the inner wall of the fixed shell 133. When the movable rod 132 moves, it will squeeze the spring 134 through the push ring 323. After the arc plate 412 leaves the ball head 321, the movable rod 132 will return to its original position under the action of the spring 134.

[0030] A powder outlet pipe 121 is fixedly connected to the top left side of the cover plate 12. A separator 122 is provided below the cover plate 12. A rotating rod 123 is fixedly connected to the top of the separator 122. The top of the rotating rod 123 passes through the cover plate 12 and extends to the outside. The rotating rod 123 is rotatably connected to the cover plate 12. A belt pulley 124 is fixedly connected to the top of the rotating rod 123. The powder generated by grinding is selected by the separator 122, and then the powder is discharged from the powder outlet pipe 121.

[0031] A baffle 111 is fixedly connected to the top of the inner wall of the base 11. A support plate 142 is in contact with the bottom of the grinding roller 141. A rotating rod 143 is fixedly connected to the top of the inner wall of the grinding roller 141. The bottom of the rotating rod 143 passes through the base 11 and extends into the baffle 111. A belt pulley 144 is fixedly connected to the bottom of the rotating rod 143. By setting the grinding roller 141, the material enters the space between the grinding roller 141 and the mill housing 1. The grinding roller 141 grinds the material. Since the top of the grinding roller 141 is conical, the material can be guided and ground smoothly. This grinding method can grind more thoroughly. Compared with the traditional rolling mill method, it reduces splashing and slippage and improves the grinding effect.

[0032] The outer surface of the grinding roller 141 is provided with several protrusions. A protruding ring 421 is fixedly connected to the top of the support plate 142. The outer side of the protruding ring 421 contacts the inner wall of the grinding roller 141. The bottom of the support plate 142 is fixedly connected to the top of the base 11. The bottom of the grinding roller 141 rotates on the support plate 142. The protruding ring 421 plays a sealing role to prevent material from entering the interior of the grinding roller 141.

[0033] The arc plate 412 is arc-shaped, the top of the grinding roller 141 is conical, and the top of the base 11 has several slag discharge ports 15. The fine particles generated by grinding fall onto the top of the base 11 and are then discharged through the slag discharge ports 15.

[0034] One specific application of this embodiment is:

[0035] Connecting belt pulley 124 and belt pulley 144 to the motor via belts will cause the two motors to drive belt pulleys 124 and 144 to rotate respectively. Belt pulley 144, in turn, drives grinding roller 141 to rotate via rotating rod 143. The bottom of grinding roller 141 rotates on support plate 142. The convex ring 421 acts as a seal to prevent material from entering the interior of grinding roller 141. Belt pulley 124, via rotating rod 123, drives separator 122 to rotate, separating cement... Material is conveyed into the mill housing 1 from the feed pipe 13. The material enters the mill housing 1 and is then ground on the grinding assembly 14. Subsequently, the material enters the space between the grinding roller 141 and the mill housing 1, where the grinding roller 141 grinds the material. The resulting powder is separated by the separator 122 and then discharged from the powder outlet pipe 121. Fine particles from the grinding process fall onto the top of the base 11 and are then discharged through the slag discharge port 15. Because the top of the grinding roller 141 is conical... The placement of the grinding roller 141 allows the material to be guided and ground smoothly, resulting in more thorough grinding. Compared to traditional roller mills, it reduces splashing and slippage, improving the grinding effect. During rotation, the grinding roller 141 drives the arc-shaped plate 412 to rotate via the fixed rod 411. When the arc-shaped plate 412 contacts the ball head 321, it pushes the ball head 321, causing the movable rod 132 to slide on the fixed frame 131 and compress the spring 134 via the push ring 323. Since both the right side of the movable rod 132 and the right side of the fixed shell 133 are tapered, it facilitates material discharge. At the same time, when the movable rod 132 moves, it will drive the cleaning rod 322 to move together. The cleaning rod 322 will clear the inside of the feed pipe 13. After the arc plate 412 leaves the ball head 321, the movable rod 132 will be reset by the action of the spring 134. This reciprocating motion can continuously clear the feed pipe 13, reduce the occurrence of blockages, and thus improve the efficiency of the mill without the need for the operator to stop the equipment.
