Description

Technical Field

[0001] This utility model relates to the field of grate technology, specifically a new type of high-efficiency grate. Background Technology

[0002] A grate is a plate-shaped component with fine pores or strip-shaped slots, usually made of metal (such as high manganese steel or cast iron) or wear-resistant non-metallic materials. Its surface has regularly arranged holes or slots, and it is mainly used for screening, filtering, ventilation, or controlling the particle size of materials. In the industrial field, grates are widely used in equipment such as crushers, ball mills, and rotary kilns to achieve functions such as separating coarse and fine particles, filtering impurities, or ventilation and heat dissipation by intercepting or guiding materials.

[0003] In industrial production, grates are core components of equipment such as crushers, ball mills, and grate coolers, mainly used for material screening, filtration, and particle size control. However, existing grates generally suffer from performance degradation due to material blockage during use. When processing materials containing fine particles, fibrous impurities, or wet and sticky materials, the materials are easily stuck in the pores or slots of the grate, forming blockages. Once blocked, cleaning is difficult, requiring frequent shutdowns for disassembly, which not only increases maintenance costs but also reduces production efficiency. Therefore, a new type of high-efficiency grate is proposed to solve the above-mentioned problems. Utility Model Content

This solves the problem that in industrial production, grates, as core components of equipment such as crushers, ball mills, and grate coolers, are mainly used for material screening, filtration, and particle size control. However, existing grates commonly suffer from performance degradation due to material clogging. When processing materials containing fine particles, fibrous impurities, or wet, sticky materials, the material easily gets stuck in the pores or slots of the grate plate, forming a blockage. Cleaning after clogging is difficult, requiring frequent shutdowns and disassembly, which not only increases maintenance costs but also reduces production efficiency.

[0024] 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.

[0025] In the embodiments, by Figure 1-4 A novel high-efficiency grate is provided. This utility model includes a grate body 1 and grate holes 2 opened at the top of the grate body 1. Two parallel baffles 3 are fixedly connected to the bottom of the grate body 1. Two parallel and synchronously rotating transmission threaded rods 4 are rotatably connected between the two baffles 3. A power component 5 for driving the transmission threaded rod 4 to rotate is provided on the outer side of one of the baffles 3. A movable frame 6 is connected to the outer side of the transmission threaded rod 4 through threaded transmission. A cleaning component 7 for periodically unblocking the grate holes 2 is fixedly connected to the top of the movable frame 6.

[0026] The structure, including baffle 3, transmission threaded rod 4, power component 5, moving frame 6, and cleaning component 7, enables the periodic automatic unblocking and cleaning of the grate holes 2, eliminating the need for frequent manual operation. This improves the convenience and efficiency of using the grate. The overall structure is compact and reasonable, with each component working closely together to ensure the stable realization of the cleaning function.

[0027] Among them, the bottom of the grate body 1 is fixedly connected to a limiting protective plate 8. The outer side of the limiting protective plate 8 is in sliding contact with the outer side of the moving frame 6. The inner side of the limiting protective plate 8 is rotatably connected to the outer side of the transmission threaded rod 4 through a bearing. The limiting protective plate 8 restricts the movement trajectory of the moving frame 6 and supports the transmission threaded rod 4.

[0028] The setting of the limit protection plate 8 effectively restricts the movement trajectory of the moving frame 6, avoids collision between the moving frame 6 and the cleaning component 7, and at the same time supports the transmission threaded rod 4, enhances the stability of the transmission threaded rod 4 when rotating, and thus ensures the reliable operation of the entire cleaning process.

[0029] The power assembly 5 includes a drive motor 51 fixedly connected to the outside of one of the baffles 3, a power worm gear 52 fixedly connected coaxially to the outside of the output shaft of the drive motor 51, and a power worm wheel 53 fixedly connected to the outside of the transmission threaded rod 4. The helical teeth of the power worm gear 52 mesh with the annular teeth of the power worm wheel 53 for transmission.

[0030] The power assembly 5 achieves stable power transmission through the cooperation of the drive motor 51, the power worm 52, and the power worm wheel 53. The meshing transmission of the worm and worm wheel has the advantages of compact structure, stable transmission ratio, and low noise, and can reliably drive the transmission threaded rod 4 to rotate, providing a stable power source for the movement of the moving frame 6 and the cleaning assembly 7.

[0031] The cleaning component 7 includes a connecting spring 71 fixedly connected to the top of the movable frame 6, a connecting plate 72 fixedly connected to the other end of the connecting spring 71, and a cleaning block 73 fixedly connected to the top of the connecting plate 72.

[0032] The connecting spring 71 creates an elastic connection between the cleaning block 73 and the moving frame 6. When the cleaning block 73 contacts the grate hole 2, it can adapt to a certain positional deviation, reduce rigid collisions, protect the cleaning block 73 and the grate hole 2, and at the same time ensure that the cleaning block 73 can make close contact with the grate hole 2, thereby improving the cleaning effect.

[0033] The cleaning block 73 is inclined at 45° on the outside. Multiple cleaning blocks 73 are distributed at intervals along the length of the moving frame 6. The top of each cleaning block 73 is closely attached to the bottom wall of the grate body 1. The central axis of the cleaning block 73 corresponds to the central axis of the grate hole 2 and is located below it. When the cleaning block 73 moves with the moving frame 6, it can be inserted into the grate hole 2 to remove blockages.

[0034] The inclined setting and reasonable distribution of the cleaning block 73 enable it to be inserted into the grate hole 2 more efficiently, fit tightly against the bottom wall of the grate body 1, and the corresponding central axis ensures the accuracy of insertion. This effectively removes the blockage in the grate hole 2, improves the grate's unblocking efficiency, ensures the grate hole 2 is unobstructed, and maintains the normal working performance of the grate.

[0035] The inner wall of the grate hole 2 is polished to form a smooth surface. The grate hole 2 has a rectangular through hole structure. The width of the grate hole 2 is equal to the width of the cleaning block 73 and the tolerance fit is a clearance fit.

[0036] The smooth surface of the inner wall of the grate hole 2 and the gap fit with the cleaning block 73 reduce the resistance when the cleaning block 73 is inserted into and removed from the grate hole 2, making the cleaning process smoother and avoiding jamming caused by excessive friction. This improves the efficiency and reliability of the cleaning operation. At the same time, the rectangular through hole structure ensures the stability of the grate hole 2 and the accurate insertion of the cleaning block 73.

[0037] Working principle:

[0038] When it is necessary to clean the grate 2, starting the drive motor 51 will cause the power worm gear 52 to rotate, which will drive the transmission threaded rod 4 to rotate through the power worm wheel 53. Subsequently, the cleaning component 7 carried by the moving frame 6 will move, so that the cleaning block 73 will be inserted into the inside of the grate 2, thereby cleaning the inside of the grate 2. The whole cleaning process is simple and quick.
