Description

Technical Field

[0001] The utility model belongs to the technical field of high-pressure roller mills, and in particular relates to a side baffle plate structure for enhancing the wear resistance of a wear-resistant body of the side baffle plate. Background Art

[0002] High-pressure roller grinding technology was initially used in the cement industry. Due to its product structure advantages, ore crushing characteristics and ability to significantly reduce power consumption, it has now been widely used in metal and non-metal mining fields such as iron ore, copper ore, gold and silver ore, and diamond ore.

[0003] The crushing principle is that the material continuously enters the middle of two rollers rotating in opposite directions from the top, and is discharged downward after being squeezed and crushed. In this process, the material will be discharged to both sides of the roller and release a large pressure to form a high-pressure wear area. The side baffles are installed at both ends of the roller to block the outflow of materials. The wear-resistant working surface of the wear-resistant base on the side baffle is set in the high-pressure wear area, forming a closed extrusion and crushing space with the two rollers to ensure that all materials flow to the next process after being squeezed and crushed. If the wear-resistant working surface is worn too much or damaged, it cannot effectively block the material, which will cause the un-extruded and crushed materials to flow out from both ends of the roller or enter the next process, resulting in an increase in the amount of returned materials and affecting product indicators.

[0004] In the current field of high-pressure roller mills (roller presses, roller crushers), the main means to improve the wear resistance of the wear-resistant working surface in the high-pressure wear area of ​​the side baffle is usually to weld wear-resistant materials or inlay studs made of wear-resistant materials. The coverage rate of wear-resistant materials is usually around 40%. The service life is extremely short, and it needs to be replaced every 4-10 weeks on average. Under the erosion and wear of the high-pressure material flow, the body of the wear-resistant working surface and the wear-resistant materials inlaid on its surface wear together, and need to be replaced as a whole, and the spare parts cost is high.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions.

[0007] The utility model provides a side baffle structure for enhancing the wear resistance of the wear-resistant body of the side baffle, comprising a side baffle, a wear-resistant base and a wear-resistant block, characterized in that the lower part of the side baffle is connected to the wear-resistant base, the wear-resistant base is a groove-type structure, the inner side surface of the wear-resistant base is provided with a plurality of mounting grooves, the wear-resistant block can be detachably inserted into each of the mounting grooves, the wear-resistant block protrudes outwardly from the inner side surface of the wear-resistant base, and the outer side surface formed by all the wear-resistant blocks forms a complete wear-resistant working surface, and the wear-resistant base is detachably provided with a baffle for preventing the wear-resistant block from falling off on the outside of the wear-resistant block.

[0008] Furthermore, the wear-resistant base is a structure that is longer at the top and shorter at the bottom, the mounting groove is longitudinally arranged in the groove-shaped structure of the wear-resistant base, the wear-resistant blocks are longitudinally arranged in the mounting groove, and the wear-resistant base is detachably connected to a lower baffle plate below the wear-resistant block to prevent the middle wear-resistant block from falling off, and the wear-resistant base is detachably connected to a side baffle plate on the outer side of the wear-resistant block to prevent the wear-resistant blocks on both sides from falling off.

[0009] Furthermore, openings are correspondingly arranged at both ends of the shorter mounting grooves on both sides of the mounting grooves in the wear-resistant base, and the side baffles are connected to the openings.

[0010] Furthermore, the mounting groove is a wedge-shaped groove, a dovetail groove, a square groove, a rectangular groove or a cylindrical groove, the inner side of the wear-resistant block is arranged as a wedge-shaped, dovetail-shaped, square, rectangular or cylindrical mounting portion matching the shape of the mounting groove, and the outer side of the wear-resistant block is arranged as a rectangular plane, and all rectangular planes constitute a wear-resistant working surface.

[0011] Furthermore, after the wear-resistant block is inserted into the installation groove, the wear-resistant block and the installation groove are firmly bonded by anaerobic adhesive.

[0012] The beneficial effects of the utility model.

[0013] The utility model makes structural improvements so that the wear-resistant working surface corresponding to the high-pressure wear area can be completely covered by the wear-resistant block, avoiding the wear-resistant base from participating in the wear. The wear-resistant block has a higher wear resistance than the original side baffle structure with a low coverage rate of the high-wear-resistant area due to the high wear resistance of its material. At the same time, it can be realized that the wear parts can be disassembled and replaced more easily by removing the baffle corresponding to the replacement position without replacing the wear-resistant base. The replacement process is simpler and more convenient, greatly improving the work efficiency of daily maintenance. The damaged or worn parts of the wear-resistant block can be replaced separately to reduce maintenance costs. Combining the above advantages, the service life of the side baffle can be greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] As shown in the accompanying drawings, this embodiment provides a side baffle structure for enhancing the wear resistance of the side baffle wear-resistant body, including a side baffle 1, a wear-resistant base 2 and a wear-resistant block 3.

[0021] The lower part of the side baffle 1 is connected to the wear-resistant base 2. The wear-resistant base 2 is a groove-shaped structure that is longer on the top and shorter on the bottom. A plurality of mounting grooves 4 are arranged on the inner side of the wear-resistant base 2. The mounting grooves 4 are arranged longitudinally. The mounting grooves 4 can be wedge-shaped grooves, dovetail grooves, square grooves, rectangular grooves or cylindrical grooves. The depth of the mounting grooves 4 can be set to 5mm-20mm.

[0022] A wear-resistant block 3 can be removably inserted into each mounting groove 4. The inner side of the wear-resistant block 3 is arranged with a wedge-shaped, dovetail-shaped, square, rectangular or columnar mounting portion matching the shape of the mounting groove 4. The height of the mounting portion is 5mm-20mm. The wear-resistant block 3 is longitudinally installed in the mounting groove 4 of the wear-resistant base 2 due to its shape and structural characteristics.

[0023] When the wear-resistant block 3 is installed in the installation groove 4, anaerobic adhesive can also be used to bond the wear-resistant block 3 to the installation groove 4 of the wear-resistant base 2 to ensure that the wear-resistant block 3 is firmly installed.

[0024] The wear-resistant block 3 protrudes outward from the inner side surface of the wear-resistant base 2, the protruding part is 5mm-30mm, the outer side of the protruding part is a rectangular plane, and all the outer rectangular planes constitute the entire wear-resistant working surface, so that the wear-resistant working surface is fully covered with high-wear-resistant materials. Compared with the side baffles 1 of other structures, the wear-resistant material coverage rate is significantly improved, which greatly improves the service life of the side baffle 1.

[0025] A lower baffle plate 5 is detachably connected to the wear-resistant base 2 at the lower outside of the wear-resistant block 3 to prevent the middle wear-resistant block 3 from falling off; openings 7 are correspondingly provided at the lower ends of the short mounting grooves 4 on both sides of the wear-resistant base 2, and the wear-resistant base 2 is detachably connected to the outer side of the wear-resistant block 3 to prevent the wear-resistant blocks 3 on both sides from falling off, and the side baffle plates 6 are connected to the openings 7.

[0026] When replacing worn parts, after pulling out the side baffle 1 from the equipment, you only need to remove the baffle 5 and the side baffle 6 and pull out the wear-resistant block 3 for replacement. If the wear-resistant block 3 and the wear-resistant base 2 are bonded with anaerobic adhesive during installation, they can be easily removed after baking. Compared with the original structure, the whole process greatly reduces the number of parts that need to be disassembled and the difficulty of disassembly, thereby improving the efficiency of replacement. At the same time, the reduction in parts can also reduce equipment costs and spare parts costs.

[0027] It can be understood that the above specific description of the utility model is only used to illustrate the utility model and is not limited to the technical solution described in the implementation mode of the utility model. Ordinary technicians in the field should understand that the utility model can still be modified or replaced by equivalents to achieve the same technical effect; as long as the use requirements are met, they are within the protection scope of the utility model.
