Description

Technical Field

[0001] This utility model relates to the field of coal-based activated carbon processing technology, specifically a grinding device for coal-based activated carbon processing. Background Technology

[0002] Coal-based activated carbon is generally black cylindrical activated carbon, or irregularly shaped coal-based granular activated carbon. Cylindrical activated carbon is also known as columnar carbon. It is generally made from powdered raw materials and binders through mixing, extrusion molding, carbonization, activation and other processes. To make coal-based activated carbon into a powder form, it needs to be ground multiple times.

[0003] In response, Chinese patent application number CN202220493533.8 discloses a grinding device for activated carbon processing, including a grinding box, a feeding box connected to the lower end of the grinding box, a discharge cylinder connected to the lower end of the feeding box, an electric telescopic rod fixed to the outside of the grinding box, a pair of scrapers fixed to the telescopic end of the electric telescopic rod, a first fixing block fixed to the front wall of the grinding box, a second motor fixed to the side wall of the first fixing block, a first threaded rod fixed to the drive end of the second motor, a second fixing block fixed to the rear wall of the grinding box, a first motor fixed to the side wall of the second fixing block, a second threaded rod fixed to the drive end of the first motor, a gantry frame screwed onto the first threaded rod and the second threaded rod, a grinding device installed on the lower wall of the gantry frame, and an installation plate inserted into the grinding box.

[0004] The device grinds materials on a mounting plate by setting up grinding rollers. When there are large pieces of material on the mounting plate, the grinding rollers are cylindrical and their movement cannot hold the material down, but can only push the material to move. As a result, the material cannot be fully ground, and the grinding effect of the device is not ideal.

[0005] Therefore, in order to solve the above problems, a grinding device for processing coal-based activated carbon is proposed. Summary of the Invention

[0006] The purpose of this utility model is to provide a grinding device for processing coal-based activated carbon, in order to solve the problem mentioned in the background art that the prior art device grinds the material on the mounting plate by setting grinding rollers. When there are large pieces of material on the mounting plate, the grinding rollers are cylindrical and their movement cannot press down the material, but can only push the material to move, thus failing to grind the material sufficiently, resulting in an unsatisfactory grinding effect of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for processing coal-based activated carbon, comprising: a housing, a filter plate installed on the inner side of the housing, a hopper on the bottom surface of the housing, a threaded rod movably installed on the rear end of the top surface of the housing via a bearing, and a motor fixedly installed on the left side wall of the housing;

[0008] The housing is equipped with a grinding structure, which includes a threaded block. The threaded block is movably mounted on the outside of a threaded rod via a thread. A material frame is fixedly connected to the bottom end of the threaded block. A cylinder is fixedly mounted on the top surface of the threaded block. A mounting frame is fixedly connected to the extended end of the cylinder. A grinding roller is movably mounted on the bottom end of the mounting frame via a bearing. A movable frame is inserted into the top surface of the mounting frame. A pressure plate is fixedly connected to the bottom end of the movable frame. A hydraulic cylinder is fixedly mounted in the middle of the top surface of the mounting frame.

[0009] Preferably, the front end of the threaded block is slidably connected to the front end of the top surface of the housing.

[0010] Preferably, the bottom surface of the material frame is in contact with the top surface of the box.

[0011] Preferably, the roller is located on the upper side of the middle of the material frame.

[0012] Preferably, the pressure plate is provided in two sets, and the two sets of pressure plates are respectively located on the left and right sides of the roller, and the pressure plate is in contact with the surface of the roller.

[0013] Preferably, the extended end of the hydraulic cylinder is fixedly connected to the movable frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting up vertically movable pressure plates on both sides of the grinding roller, this utility model can crush large pieces of material when they are present next to the grinding roller, thereby reducing the volume of the material and making it easier for the grinding roller to grind the material, thus improving the practicality of the device.

[0015] This invention features a grinding structure. Material is fed into the inner side of the material frame. Activating the cylinder lowers the mounting frame, which in turn lowers the grinding roller. The roller descends to the inner side of the material frame. Activating the motor rotates the threaded rod, which is threadedly connected to a threaded block. The rotation of the threaded rod causes the threaded block to move left and right on the housing, which in turn moves the material frame and grinding roller left and right. This grinds the material on the top surface of the filter plate inside the material frame. As the material frame moves, it scrapes away material, allowing it to move across the top surface of the filter plate and pass through the filter plate for discharge via the hopper. Activating the hydraulic cylinder lowers the movable frame, which in turn lowers the pressure plate outside the grinding roller. As the pressure plate descends, it scrapes away material adhering to the surface of the grinding roller and crushes large pieces of material beside the roller, reducing the material's volume and making it easier for the roller to grind it, thus improving grinding efficiency.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides an embodiment of a grinding device for processing coal-based activated carbon:

[0023] The housing 1, filter plate 11, hopper 12, threaded rod 13, motor 14, cylinder 23 and oil cylinder 28 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0024] A grinding device for processing coal-based activated carbon includes: a housing 1, a filter plate 11 installed on the inner side of the housing 1, a feeding hopper 12 on the bottom surface of the housing 1, a threaded rod 13 movably installed on the rear end of the top surface of the housing 1 via a bearing, and a motor 14 fixedly installed on the left side wall of the housing 1.

[0025] A grinding structure 2 is installed on the housing 1. The grinding structure 2 includes a threaded block 21, which is movably installed on the outside of the threaded rod 13 via a thread. A material frame 22 is fixedly connected to the bottom end of the threaded block 21. A cylinder 23 is fixedly installed on the top surface of the threaded block 21. A mounting frame 24 is fixedly connected to the extended end of the cylinder 23. A grinding roller 25 is movably installed on the bottom end of the mounting frame 24 via a bearing. A movable frame 26 is inserted into the top surface of the mounting frame 24. A pressure plate 27 is fixedly connected to the bottom end of the movable frame 26. A hydraulic cylinder 28 is fixedly installed in the middle of the top surface of the mounting frame 24. By setting up movable pressure plates 27 on both sides of the grinding roller 25, when there are large pieces of material next to the grinding roller 25, the material can be squeezed and crushed, reducing the volume of the material and making it easier for the grinding roller 25 to grind the material, thus improving the practicality of the device.

[0026] Furthermore, the front end of the threaded block 21 is slidably connected to the front end of the top surface of the housing 1. The starting motor 14 can drive the threaded rod 13 to rotate. The threaded rod 13 is threadedly connected to the threaded block 21. The rotation of the threaded rod 13 can drive the threaded block 21 to move left and right on the housing 1.

[0027] Furthermore, the bottom surface of the material frame 22 is in contact with the top surface of the box 1. When the material frame 22 moves, it can scrape the material on the filter plate 11, making it easier for the material to pass through the filter plate 11 and causing the material to gather in the middle of the top surface of the filter plate 11.

[0028] Furthermore, the grinding roller 25 is located on the upper side of the middle of the material frame 22, and the grinding roller 25 can be lowered to the inside of the material frame 22 to facilitate grinding of the material inside the material frame 22.

[0029] Furthermore, two sets of pressure plates 27 are provided, with the two sets of pressure plates 27 located on the left and right sides of the roller 25 respectively. The pressure plates 27 are in contact with the surface of the roller 25. When the pressure plates 27 move, they can scrape off the material adhering to the surface of the roller 25 and crush large pieces of material next to the roller 25.

[0030] Furthermore, the extended end of the hydraulic cylinder 28 is fixedly connected to the movable frame 26, and the hydraulic cylinder 28 provides power for the lifting and lowering of the pressure plate 27.

[0031] Working principle: During processing, the material is fed into the inner side of the material frame 22. The cylinder 23 is started, which drives the mounting frame 24 to descend. The mounting frame 24 then drives the grinding roller 25 to descend. The grinding roller 25 descends to the inner side of the material frame 22. The motor 14 is started, which drives the threaded rod 13 to rotate. The threaded rod 13 is threadedly connected to the threaded block 21. The rotation of the threaded rod 13 drives the threaded block 21 to move left and right on the box 1. The threaded block 21 then drives the material frame 22 and the grinding roller 25 to move left and right. This grinds the material located on the top surface of the filter plate 11 inside the material frame 22. When the material frame 22 moves, it scrapes the material, allowing the material to move on the top surface of the filter plate 11, making it easier for the material to pass through the filter plate 11 and be discharged through the hopper 12.

[0032] When the hydraulic cylinder 28 is activated, the movable frame 26 is lowered. The movable frame 26 drives the pressure plate 27 to descend outside the grinding roller 25. When the pressure plate 27 descends, it scrapes off the material adhering to the surface of the grinding roller 25. The pressure plate 27 can also crush large pieces of material next to the grinding roller 25, making the material smaller and easier for the grinding roller 25 to grind on the material, thus improving the grinding efficiency of the material.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
