Description

Technical Field

[0001] The utility model relates to the technical field of protective lining plates for vibrating feeders, in particular to a polyurethane ceramic composite lining plate. Background Art

[0002] The feeding end of vibrating equipment such as vibrating feeders, vibrating conveyors, and vibrating screens is usually equipped with a drop section to receive the material given by the system in the previous stage. A large amount of material and a high drop will cause a strong impact on the equipment. Moreover, as the equipment continues to run, the parts where the material flows through will be worn or even damaged, causing great damage to the equipment and reducing the service life of the equipment. In order to prevent wear on the equipment body, linings are usually installed at the parts where the material impacts and flows through to protect the equipment. As a wearing part, the lining is required to have both high wear resistance and impact resistance, and it must also be easy to disassemble and assemble. In the prior art, ordinary steel linings or alloy wear-resistant linings are bolted to the equipment to protect the equipment. This type of lining has poor wear resistance, a short service life, and requires frequent replacement. Moreover, this type of lining can only prevent wear but not impact.

[0003] With the development of new material technology, composite linings have been more and more widely used due to their excellent performance. The current production process of composite linings is relatively complicated, and the steel plate substrate must undergo pretreatment processes such as cleaning, sandblasting, glue spraying, and brushing. Vulcanization needs to be carried out in two steps, first vulcanizing the ceramic column (sheet) and the substrate, and then vulcanizing the substrate and the steel plate substrate. Even after the steel plate base pretreatment process and secondary vulcanization process, the composite lining produced in this way will still cause the matrix to fall off under continuous impact, and the ceramic column (piece) is also easy to fall off under external force impact. Once a ceramic column (piece) is broken, the external force will directly impact the matrix, the matrix is ​​damaged, and other ceramic pieces are more likely to fall off, thereby reducing the service life. In addition, traditional steel liners, alloy wear-resistant liners and current composite liners are all connected to the equipment by bolts. The liner and the equipment are rigidly connected, and can only rely on the material properties of the liner itself to alleviate part of the impact force. The remaining impact force will still be transmitted to the equipment body, reducing the service life of the equipment; and vibrating equipment such as vibrating feeders, vibrating conveyors, and vibrating screens are usually used in harsh working environments. The bolts are easily rusted by rain and mud, making it difficult to replace the liner. In addition, due to the high-frequency and violent vibration of the vibrating equipment, the bolts are easy to loosen, and they need to be frequently checked and tightened regularly during use. The bolts usually protrude outside the liner, and there is also a risk of damage during transportation.

[0004] In summary, the traditional steel liner and alloy wear-resistant liner have poor wear resistance, short service life, poor impact resistance, poor protection of equipment, etc., while the commonly used rubber ceramic composite liner and polyurethane ceramic composite liner have defects such as complex production process, easy shedding of rubber or polyurethane matrix and ceramic column (sheet). At the same time, both are connected to the equipment with bolts, the liner is difficult to disassemble and assemble, and the maintenance cost is high, which brings many inconveniences to actual use. Utility Model Content

[0005] The utility model aims to provide a polyurethane ceramic composite lining plate to solve the problems of poor impact resistance, poor wear resistance and high maintenance cost of traditional vibrating feeder protective lining plates.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A polyurethane ceramic composite lining comprises a polyurethane substrate, ceramic columns, substrate clips and an equipment protection surface; the ceramic columns are arranged in the polyurethane substrate; the ceramic columns are arranged in a rectangular array structure in the polyurethane substrate; the ceramic columns are cast and fixed in the polyurethane substrate; clip grooves are arranged at both ends of the bottom of the polyurethane substrate; the clip grooves are arranged in a hemispherical structure; the clip grooves are arranged on the substrate clip strips; a buffer notch is embedded in the bottom of the polyurethane substrate; the substrate clip strips are arranged on the equipment protection surface; the polyurethane substrate is fixed above the equipment protection surface through the substrate clip strips.

[0008] Furthermore, the ceramic column is arranged in a truncated cone structure.

[0009] Furthermore, a ceramic column positioning hole is arranged transversely through the middle of the ceramic column.

[0010] Furthermore, the diameter of the lower end surface of the ceramic column is 2-6 mm larger than the diameter of the upper end surface.

[0011] Furthermore, the upper end surface of the ceramic column protrudes from the polyurethane matrix by 1-3 mm.

[0012] Furthermore, a clamping strip protrusion is arranged on the top of the base clamping strip; the clamping strip protrusion is arranged in a circular structure; and the clamping strip protrusion is arranged on the clamping strip base.

The polyurethane ceramic composite lining plate in this technology is arranged at the feeding end of the vibration equipment and installed on the special card strips, and a modular splicing structure is adopted. The polyurethane ceramic composite lining installed can only replace the local lining when the local wear is serious, effectively reducing the use cost, and it is fixed with a special card strip, which is convenient for quick replacement of the lining; the polyurethane ceramic composite lining is not directly fitted to the protected surface of the equipment, but there is a gap, and there is a ︹-shaped notch on the bottom of the lining, which can increase the deformation ability of the lining. The connection between the lining and the equipment body is a semi-flexible connection. In addition to being able to rely on the polyurethane material properties of the lining to alleviate part of the impact force, due to the gap between the lining and the equipment, the lining also has a certain deformation ability. When the lining is deformed, it will not cause direct impact on the equipment body, and can unload part of the impact force, so that the impact force transmitted to the equipment body is reduced again. The polyurethane ceramic composite lining of the utility model has better impact resistance than the current rubber ceramic composite lining and polyurethane ceramic composite lining, so that the equipment is better protected.

[0015] 2. The ceramic column is set as a truncated cone structure. By setting the ceramic column as a truncated cone structure, during the integral casting and molding process of the polyurethane matrix, the ceramic column with a conical structure is beneficial to improving the structural connection strength between the ceramic column and the polyurethane matrix.

[0016] 3. A ceramic column positioning hole is horizontally penetrated in the middle of the ceramic column, so that when the polyurethane matrix is ​​poured, polyurethane can be poured into the hole through the ceramic column positioning hole to achieve a tight combination of the polyurethane matrix and the ceramic column.

[0017] 4. The diameter of the lower end face of the ceramic column is 2-6 mm larger than the diameter of the upper end face, and the wrapping performance of the polyurethane matrix on the ceramic column can be greatly enhanced by setting the ceramic column to a conical structure.

[0018] 5. The upper end surface of the ceramic column protrudes from the polyurethane matrix by 1-3 mm, so that the ceramic column can be provided with a protruding polyurethane matrix to receive the impact of materials and prevent the materials from directly impacting the polyurethane matrix and causing damage to the matrix.

[0019] 6. The protrusion of the card strip is a circular structure; the protrusion of the card strip is set on the base of the card strip, which can realize the interference connection between the special card strip and the liner, and the connection is tighter. The special card strip adopts a circular protrusion, and the angle restriction is small when the liner is installed, which is easier to load and unload the liner; when installing the liner, just use a rubber hammer to knock it in, which improves the assembly efficiency; at the same time, the liner adopts a small area, multi-module combined structure. When the local wear is serious, only the local liner can be replaced, which effectively reduces the replacement cost; when replacing, insert a knockable flat-head screwdriver into the joint of the two liner boards, gently pry up the liner to be replaced, and push the liner upward with both hands to remove the liner from the special card strip.
