Description

Technical Field

[0001] The utility model belongs to the technical field of steel smelting equipment, and in particular relates to a special wear-resistant block for a single-roller dump box of a sintering machine and a sintering machine. Background Art

[0002] Sintering machine is a common equipment in the metallurgical industry, which is used to sinter ore into block materials for blast furnace smelting. During the working process of the sintering machine, the sintered ore needs to be screened by the grate bars and dumped by the dump box to achieve smooth flow of materials. However, although the wear-resistant block on the top of the dump box plays a certain protective role in actual use, it has its own defects, leading to a series of problems, affecting the normal operation and life of the entire sintering machine.

[0003] First, although the five wear-resistant blocks on the top are originally designed to protect the top frame of the dump box, they are susceptible to severe friction and wear during long-term high-intensity work. During the operation of the sintering machine, the grate bars frequently come into contact with the wear-resistant blocks. In addition, the particles of the sintered ore are relatively hard and large, which causes the wear resistance of the wear-resistant blocks to gradually decrease. This wear phenomenon of the wear-resistant blocks not only affects their protective function, but also causes the sintered ore to enter the dump box, accelerating the wear of the top frame of the dump box, thereby reducing the service life of the entire sintering machine.

[0004] Secondly, due to the serious wear of the wear-resistant block, the effect of cleaning the sticky material on the sintering machine grate is also greatly reduced. During the flow of sintered ore, it is easy to adhere to the grate to form sticky material, and the wear-resistant block on the top should have a cleaning effect. However, due to the uneven surface of the wear-resistant block after wear, the cleaning effect is greatly reduced. The sintered ore adhering to the grate cannot be effectively cleaned and accumulates on the grate to form agglomerates, which further affects the normal operation of the sintering machine.

[0005] In addition, the wear-resistant block design in the prior art has certain structural defects. Since the wear-resistant block on the top is fixed on the dump box, it is very difficult to replace and maintain it. Once the wear-resistant block is found to be severely worn, it is necessary to stop the machine for replacement, which not only wastes a lot of production time, but also increases the difficulty and cost of maintenance. Moreover, during the replacement process, a certain part of the sintering machine structure may need to be disassembled, affecting the normal operation of the entire production line.

[0006] In summary, the original wear-resistant block on the top of the single-roller dump box of the sintering machine has defects such as severe wear, poor cleaning effect, and difficulty in replacement and maintenance, which has caused serious impact on the sintering machine during long-term operation, thereby affecting the service life of the equipment. In order to improve the performance and life of the sintering machine, it is urgent to improve the existing technology. Utility Model Content

[0007] In view of the problems existing in the prior art, the utility model provides a special wear-resistant block for a single-roller dump box of a sintering machine and a sintering machine, which solves the problems of severe wear of the wear-resistant block, poor cleaning effect, and difficulty in replacement and maintenance in the prior art.

[0008] The utility model is implemented as follows: a special wear-resistant block for a single-roller material dump box of a sintering machine includes a wear-resistant block body, which is characterized in that a ridge-shaped portion with two slopes is formed on the upper part of the wear-resistant block body, a slit is provided on the lower part of the wear-resistant block body, and a handle and a hole are provided on the side of the wear-resistant block body which pass through the two side surfaces of the wear-resistant block body and the slit.

[0009] In the above technical solution, preferably, the two slopes forming the ridge-shaped portion are an inner slope arranged close to the inner side of the dump box and an outer slope arranged close to the outer side of the dump box, and the vertical length L1 of the inner slope is greater than the vertical length L2 of the outer slope.

[0010] In the above technical solution, preferably, the slit is a rectangular long groove which passes through the wear-resistant block body longitudinally and is open at the lower end.

[0011] In the above technical solution, preferably, at least one side wall of the slot is provided with a longitudinally extending lateral sliding groove.

[0012] The utility model provides a special wear-resistant block for the single-roller dump box of the sintering machine, which has many outstanding advantages:

[0013] The first improvement is the redesign of the shape of the wear block. By thickening the top of the wear block to form a roof-like structure, the sintering ore particles can be quickly slid down, thus effectively preventing the problem of particles accumulating on the top. This design cleverly reduces the impact of wear on the dump box frame and improves the stable operation of the entire sintering machine.

[0014] Secondly, by shortening the length of the wear-resistant block, the fixing method was successfully improved. In the original design, three bolts were used for fixing, which required multiple people to collaborate in the installation when replacing it. This not only posed a safety hazard, but also consumed a lot of time and manpower. The new design uses one bolt for fixing, which not only reduces the weight of a single wear-resistant block without affecting its performance, but also enables single-person operation during installation, greatly simplifying the replacement process and improving maintenance efficiency.

[0015] Thanks to the successful application of these optimization measures, the new wear-resistant blocks for sintering machines have shown remarkable results in actual use. First, no damage to the material dump box due to wear of the wear-resistant blocks has occurred in the past two years, which fully proves its excellent wear resistance. This not only effectively extends the service life of the single-roller material dump box, but also greatly reduces the equipment maintenance cost, providing reliable support for production.

[0016] In general, the newly designed wear-resistant block for the single-roller dump box of the sintering machine has successfully solved many problems of the original technology through the optimization of shape and improvement of the fixing method, and achieved more stable and efficient operation of the sintering machine. Its safety, simplicity and wear resistance provide obvious advantages for production and make positive contributions to the long-term reliable operation of the sintering machine and the reduction of maintenance costs.

[0017] Another purpose of the utility model is to propose a sintering machine, including a wear-resistant block fixing plate, which is a vertical plate body extending longitudinally, and the wear-resistant block fixing plate is provided with cylindrical holes for fitting special wear-resistant blocks for material dumping boxes at intervals, and is characterized in that: longitudinally extending limiting ribs are provided on both sides of the wear-resistant block fixing plate, and a plurality of the above-mentioned special wear-resistant blocks for material dumping boxes are longitudinally fitted on the wear-resistant block fixing plate, and the special wear-resistant blocks for material dumping boxes are fixed by bolt and nut assemblies passing through relatively positive handles and holes and cylindrical holes.
