Description

Technical Field

[0001] This utility model belongs to the field of gypsum fine material processing technology, specifically relating to a gypsum fine material roller mill. Background Technology

[0002] In the field of gypsum fine material processing, roller mills are commonly used equipment. They grind and compress gypsum fine materials into powder through the relative rotation of crushing rollers. The crushing rollers are usually fixed inside the equipment. After long-term use, a large amount of gypsum fine material residue will adhere to their outer wall. Because the crushing rollers are fixed in position, it is difficult to move them to a position that is misaligned with the inner cavity of the equipment. The space is limited when the operator cleans them, which not only makes cleaning difficult and inefficient, but also easily leads to the accumulation of residue. These residues will affect the subsequent grinding and pressing effect of gypsum fine materials, reduce the processing quality, and the long-term adhesion of residual gypsum fine materials will also aggravate the wear of the crushing rollers and shorten the service life of the equipment. Utility Model Content

[0003] This utility model provides a gypsum fine material roller mill, which solves the problem of the inconvenience of removing and cleaning the crushing roller.

[0004] This utility model provides the following technical solution: It includes a grinding mill housing, a mounting frame, and a motor A. Multiple drive wheels are mounted on the motor A and connected by belts. The grinding mill housing has mounting holes, and a support plate is slidably connected to the inner wall of the mounting holes. Two rotating plates are rotatably connected to the support plate. Square drive rods that engage with the drive wheels are mounted on the rotating plates. A crushing roller is installed between every two corresponding rotating plates. A guide plate is slidably connected to the inner wall of the grinding mill housing, and a side frame is mounted on the guide plate. A slide rail matching the side frame is opened on the inner wall of the grinding mill housing. An adjustment hole communicating with the slide rail is opened on the outer wall of the grinding mill housing. An adjustment plate is installed on the outside of the side frame. A displacement frame is installed at one end of the grinding mill housing, and a support ring is installed on the inner wall of the displacement frame. Corresponding connection holes are opened between the support ring and the support plate.

[0005] The grinding mill housing is equipped with a motor B on its outer wall. An adjusting rod is installed on the drive end of the motor B. A threaded sleeve is threadedly connected to the outer wall of the adjusting rod, and one end of the threaded sleeve is connected to the displacement frame.

[0006] The two connecting holes are connected by bolts, and the support plate and the inner wall of the support ring are matched.

[0007] One end of the guide plate is attached to the inner wall of the grinding mill housing, and the guide plate is positioned above the grinding roller.

[0008] The two crushing rollers at the same height are symmetrical, and the two ends of the crushing rollers are connected to the rotating plate by bolts.

[0009] The beneficial effects of this utility model are: the support plate can slide on the inner wall of the mounting hole, and with the adjustment and connection structure of the displacement frame and the support ring, the crushing roller can be pulled to a position that is misaligned with the inner cavity of the grinding mill, which makes it convenient for operators to clean the gypsum residue attached to the outer wall of the crushing roller, avoids the accumulation of residue from affecting subsequent processing, and effectively extends the service life of the equipment.

[0017] Please see Figures 1-5This utility model provides the following technical solution: It includes a grinding mill housing 1, a mounting frame 11, and a motor A12. Multiple drive wheels are mounted on the motor A12, and these drive wheels are connected by belts. The grinding mill housing 1 has mounting holes 2, and a support plate 21 is slidably connected to the inner wall of the mounting holes 2. Two rotating plates 22 are rotatably connected to the support plate 21. Square drive rods 13 that engage with the drive wheels are mounted on the rotating plates 22. A crushing roller 2 is installed between every two corresponding rotating plates 22. 3. A guide plate 3 is slidably connected to the inner wall of the grinding mill housing 1. A side frame 31 is installed on the guide plate 3. A slide rail 32 matching the side frame 31 is opened on the inner wall of the grinding mill housing 1. An adjustment hole 33 communicating with the slide rail 32 is opened on the outer wall of the grinding mill housing 1. An adjustment plate 34 is installed on the outside of the side frame 31. A displacement frame 24 is installed at one end of the grinding mill housing 1. A support ring 27 is installed on the inner wall of the displacement frame 24. The support ring 27 and the support plate 21 have corresponding connection holes 271.

[0018] In this implementation scheme: the mill housing 1 serves as the carrier of the supporting device. During use, the mounting bracket 11 installed on one side of the mill housing 1 provides a mounting surface for the motor A12. The motor A12's drive end connects to the belt drive pulleys, allowing the drive pulleys to rotate via a belt. The drive pulleys outside the mill housing 1 correspond to the mounting holes 2 on the mill housing 1. The support plate 21 supported by the inner wall of the mounting hole 2 is supported by the outer wall of the mill housing 1, allowing the rotating plate 22 mounted on the support plate 21 to engage with the square drive rod 13 installed at one end of the drive end. 3. Matching slots allow the drive wheel to rotate, causing the rotating plate 22 to rotate, which in turn drives the crushing rollers 23 installed between the two rotating plates 22 to rotate. This allows the two adjacent crushing rollers 23 to rotate in opposite directions, thus crushing the gypsum powder fed into the top of the grinding mill housing 1 into powder. During crushing, the guide plate 3, which is slidably connected to the inner wall of the grinding mill housing 1, can be fixed to its top outer side by the side frame 31. At this time, it can slide on the inner wall of the slide rail 32 by the side frame 31. The side frame 31 is connected to the adjustment hole 33. At this time, the side frame 31 supports the adjustment hole 33 and seals the adjustment hole 33 to prevent the gypsum powder from leaving the grinding mill housing 1 through the adjustment hole 33 and the slide rail 32. The inner cavity guides the fine gypsum material to the position between the crushing rollers 23 for grinding and pressing. After grinding and pressing, the support plate 21 can be pushed by the drive telescopic rod installed on the outside of the grinding mill housing 1. At this time, the support plate 21 slides inside the grinding mill housing 1. The other support plate 21 can be supported in the support ring 27 installed on the inner wall of the displacement frame 24. The support plate 21 and the support ring 27 can be connected through the connecting hole 271. Then, by pushing the displacement frame 24, its position is adjusted, so that the displacement frame 24 and the support plate 21 can drive the support plate 21, the rotating plate 22 and the crushing roller 23 to perform horizontal traction, so that the crushing roller 23 can slide and adjust to be in the position inside the grinding mill housing 1. At the misaligned position of the cavities, the operator can clean the outer wall of the crushing roller 23, allowing the residual gypsum material that has been squeezed and adhered to the outer wall of the crushing roller 23 to be cleaned and discharged, thus facilitating the maintenance of the device. Since the crushing roller 23 is cylindrical, in order to guide the fine material into the space between the crushing rollers 23, the bottom of the guide plate 3 needs to be positioned close to the outer wall between the crushing rollers 23 to prevent the fine material from being unable to be between the two crushing rollers 23. After stopping the grinding of the fine material, the adjusting plate 34 can be pushed upward to move the side frame 31 up the inner wall of the slide 32, thereby moving the guide plate 3 upward and misaligning the bottom of the guide plate 3 with the support plate 21 at the same height, so that the support plate 21 can be stably adjusted horizontally.

[0019] A motor B25 is installed on the outer wall of the mill housing 1. An adjusting rod 26 is installed on the drive end of the motor B25. A threaded sleeve 241 is threadedly connected to the outer wall of the adjusting rod 26. One end of the threaded sleeve 241 is connected to the displacement frame 24. The motor B25 installed on the outer wall of the mill housing 1 can drive the adjusting rod 26. The threaded sleeve 241 installed on one end of the displacement frame 24 is threadedly connected to the adjusting rod 26. When the adjusting rod 26 rotates, it can adjust the position of the adjusting rod 26 on the threaded sleeve 241, thereby adjusting the position of the displacement frame 24 and allowing the crushing roller 23 to slide and be misaligned with the mill housing 1.

[0020] The two connecting holes 271 are connected by bolts, and the inner walls of the support plate 21 and the support ring 27 match. The connecting holes 271 are connected by bolts, so that after the support plate 21 is pushed to the inner wall of the support ring 27, the inner and outer sides of the connecting holes 271 correspond, and the support plate 21 is connected by bolts, so that the displacement frame 24 can move down and pull the crushing roller 23 to move.

[0021] One end of the guide plate 3 is attached to the inner wall of the mill housing 1, and the guide plate 3 is positioned above the crushing roller 23. The guide plate 3 is attached to the inner wall of the mill housing 1, so that the guide plate 3 can block the fine material and guide the fine material to the space between the crushing rollers 23, so that the two counter-rotating crushing rollers 23 can grind and press the fine material.

[0022] Two crushing rollers 23 at the same height are symmetrical. The two ends of the crushing rollers 23 are connected to the rotating plate 22 by bolts. The symmetry of the crushing rollers 23 allows the fine material to be ground on two close outer wall parts as the crushing rollers 23 rotate, causing the fine material to be discharged downwards. The crushing rollers 23 and the rotating plate 22 are connected by bolts, so that the crushing rollers 23 are fixed between the rotating plates 22 and can rotate synchronously with the rotating plates 22.

[0023] The working principle and usage process of this utility model are as follows: First, check whether the connections of each component are firm, ensuring that the square drive rod 13 on the rotating plate 22 is tightly engaged with the drive wheel, and that the guide plate 3 is installed in place via the side frame 31 and the adjustment hole 33 is sealed. Start the motor A12, and the drive wheel drives the rotating plate 22 to rotate via belt transmission, thereby causing the two sets of crushing rollers 23 to rotate relative to each other, entering the working state. Fine gypsum material is fed from the top of the grinding mill housing 1, and the fine material enters between the two sets of crushing rollers 23 under the guidance of the guide plate 3. As the crushing rollers 23 rotate relative to each other, the fine material is crushed by the rollers, and the ground powder falls to the collection area at the bottom of the grinding mill housing 1. When it is necessary to clean the crushing rollers 23, first turn off the motor A12 to stop operation. Start motor B25, which drives the adjusting rod 26 to rotate. This rotates the displacement frame 24 via the threaded sleeve 241. The displacement frame 24 pushes the support ring 27 and the connected support plate 21 to slide on the inner wall of the mounting hole 2, pulling the crushing roller 23 to a position misaligned with the inner cavity of the grinding mill housing 1. The operator cleans the gypsum residue from the outer wall of the crushing roller 23. After cleaning, start motor B25 in reverse to reset the displacement frame 24, support ring 27, and support plate 21, returning the crushing roller 23 to the processing position. Check whether the guide plate 3 has reset and sealed the adjusting hole 33. After confirming that everything is correct, start motor A12 again to continue the roller grinding operation of gypsum fines.
