Description
Technical Field
[0001] This utility model relates to the field of grate coolers, and in particular to a wear-resistant grate plate structure for grate coolers. Background Technology
[0002] A search of Chinese patents revealed publication number CN217877156U, which discloses a grate plate for a grate cooler with an anti-seismic structure. The grate plate includes a support block fixedly connected to its lower end, a connecting block fixedly connected to its lower end, and a round rod connected between the connecting blocks. A crossbar is fitted onto the round rod, and rotating grooves are formed at both ends of the crossbar. A support rod is rotatably connected within the rotating grooves, and an elastic folding plate is fixedly connected to the support rod. This novel design is applied to a grate plate for a grate cooler with an anti-seismic structure. By incorporating the elastic folding plate, when the grate cooler is operating, dry cement is fed onto the grate plate from the inlet for cooling. During the feeding process, the rotation of the support rod on the crossbar and the elastic folding plate fixedly connected to the support rod counteract the gravity generated during feeding, preventing the grate plate from tilting and providing a certain degree of impact resistance. This prevents the grate plate from tilting and leaking due to the impact force generated during feeding.
[0003] Existing grates have poor wear resistance. In current grate cooler technology, the grate is a key component that directly contacts the material. Working in a high-temperature, high-wear environment for a long time, it is prone to wear and deformation, leading to a decline in grate performance and even the need for replacement. Currently, although some methods have been developed to enhance the wear resistance of grate by surface welding with hard alloys, once the wear-resistant layer is worn away, the entire grate still needs to be replaced, resulting in high maintenance costs and inconvenience in assembly. Generally, grates are modularly designed for easy maintenance, but they require assembly during use. This assembly typically uses multiple bolts for fixing, and tools are needed for assembly and disassembly, which is cumbersome, increases workload, reduces work efficiency, and is inconvenient to use. To solve the above problems, we propose a wear-resistant grate cooler structure. Utility Model Content
[0004] The purpose of this invention is to provide a wear-resistant grate plate structure for a grate cooler, which has the advantages of good wear resistance and easy assembly.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a wear-resistant grate cooler grate structure, including a grate body, a wear-resistant plate provided on the top of the grate body, a first fixing rod bolted to the top of the grate body, and the first fixing rod slidingly sleeved with the inner wall of the wear-resistant plate, a first rotating shaft rotatably sleeved on the inner wall of the wear-resistant plate, a turntable fixedly sleeved on the surface of the first rotating shaft, a transmission rod hinged to the surface of the turntable, a connecting rod hinged to the other end of the transmission rod, a sliding rod bolted to the other end of the connecting rod, a snap-fit connector bolted to the surface of the sliding rod, a first snap-fit hole opened on the surface of the first fixing rod, and the snap-fit connector snaps into the first snap-fit hole, and a first spring is provided between the sliding rod and the inner wall of the wear-resistant plate.
[0006] By adopting the above technical solution and setting wear-resistant plates, the wear resistance of the grate is greatly improved. By opening the cover plate and rotating the rotating head, the first rotating shaft drives the turntable to rotate. The rotation of the turntable causes the transmission rod to move the connecting rod. The movement of the connecting rod causes the slide rod to disengage the snap-fit joint from the first snap-fit hole. Then the wear-resistant plate can be removed, which makes it easy to replace the wear-resistant plate and facilitates maintenance.
[0007] The present invention is further configured such that: a second rotating shaft is rotatably sleeved on the inner wall of the grate body; a gear is fixedly sleeved on the surface of the second rotating shaft; a toothed rod meshes with the surface of the gear; an installation hole is provided on the bottom plate of the grate body; a second fixing rod is bolted to the top of the grate body, and the second fixing rod is adapted to the installation hole; a second snap-fit hole is provided on the surface of the second fixing rod, and the second snap-fit hole is adapted to one end of the toothed rod.
[0008] By adopting the above technical solution, during splicing, the second fixing rod on one grate body is inserted into the mounting hole of another grate body. The toothed rod is engaged with the second locking hole under the action of the second spring, thus fixing it and completing the installation. Using a tool to rotate the internal hexagonal rotating block, the second rotating shaft drives the gear to move the toothed rod. The moving toothed rod disengages from the second locking hole, separating the grate bodies, thereby achieving the purpose of disassembly, reducing the workload and improving work efficiency.
[0009] The present invention is further configured such that: a limiting plate is fixedly sleeved on the surface of the toothed rod, and a second spring is provided between the limiting plate and the inner wall of the grate body, and the second spring is sleeved on the surface of the toothed rod.
[0010] By adopting the above technical solution, a limiting plate and a second spring are set to prevent the rack from loosening and ensure stability.
[0011] The present invention is further configured such that a rotating head is bolted to the top of the first rotating shaft.
[0012] By adopting the above technical solution, a rotating head is set up to facilitate the rotation of the first rotating shaft.
[0013] The present invention is further configured such that an internal hexagonal rotating block is bolted to the top of the second rotating shaft.
[0014] By adopting the above technical solution, the second rotating shaft is easily rotated by setting an internal hexagonal rotating block, which facilitates disassembly and assembly.
[0015] The present invention is further configured such that one end of the snap-fit connector and one end of the toothed bar are both wedge-shaped.
[0016] By adopting the above technical solution, both one end of the snap-fit connector and one end of the toothed bar are wedge-shaped, which facilitates the fixing of the wear-resistant plate and the assembly.
[0017] The present invention is further configured such that the surface of the wear-resistant plate is integrally formed with teeth.
[0018] By adopting the above technical solution and adding teeth, the wear resistance and anti-slip performance are improved.
[0019] The present invention is further configured such that a cover plate is threadedly connected between the inner walls of the wear-resistant plate.
[0020] By adopting the above technical solution, a cover plate is installed to protect the rotating head.
[0021] In summary, this utility model has the following beneficial effects:
[0022] 1. This utility model greatly improves the wear resistance of the grate by setting a wear-resistant plate. By opening the cover plate and rotating the rotating head, the first rotating shaft drives the turntable to rotate. The rotation of the turntable causes the transmission rod to move the connecting rod. The movement of the connecting rod causes the sliding rod to disengage the snap-fit joint from the first snap-fit hole. Then the wear-resistant plate can be removed, which makes it easy to replace the wear-resistant plate and facilitates maintenance.
[0023] 2. In this utility model, during assembly, the second fixing rod on one grate body is inserted into the mounting hole of another grate body. The toothed rod, under the action of the second spring, engages with the second locking hole to fix it, thus completing the installation. Using a tool to rotate the internal hexagonal rotating block, the second rotating shaft drives the gear to move the toothed rod. The moving toothed rod disengages from the second locking hole, separating the grate bodies, thereby achieving the purpose of disassembly, reducing workload and improving work efficiency.
