Description

Technical Field

[0001] This utility model relates to the field of raw coal storage, specifically a blockage-resistant, compartmentalized raw coal storage. Background Technology

[0002] The raw coal bunker is a key facility in thermal power plants used to store raw coal and other particulate fuels and supply coal to the pulverizing system as needed. To prevent blockage during feeding, anti-blockage raw coal bunkers are required. The "Anti-blockage Divided Raw Coal Bunker" disclosed in application number "CN202420520266.8" is an increasingly mature technology. This invention describes an anti-blockage divided raw coal bunker that, without altering the original coal conveying and blending system, divides the original raw coal bunker into two compartments using a hollow double-wall partition. One compartment holds high-quality coal, and the other holds low-quality coal. At the lower end of the divided raw coal bunker, above the feeder inlet, a bidirectional gate valve with an inclined angle is installed in the hyperbolic coal hopper area. This valve can be opened on both sides according to different load and depth peak-shaving needs. The two-way gate valves on both sides supply raw coal to the coal feeder in real time, adapting to the load. Meanwhile, to improve coal flowability, a coal blockage clearing mechanism is installed at the top of the raw coal bunker to reduce blockage. However, this raw coal bunker has the following drawbacks: While the bidirectional gate valves effectively transport raw coal and prevent blockages, the bunker structure lacks compartmentalization, affecting ease of use. Therefore, it is necessary to provide a raw coal bunker that significantly improves compartmentalization and feeding operations, enhancing its practicality. Furthermore, the current bunker structure hinders the compartmentalized transport of raw coal, further complicating its usability. Therefore, it is necessary to provide a raw coal bunker that significantly improves the ease of raw coal transport. Utility Model Content

[0004] To achieve the above objectives, this utility model provides an anti-blocking compartmentalized raw coal silo, including a compartmentalization component and a feeding component; The compartmenting assembly includes a support mechanism, inside which a raw coal bunker body is installed. A partition plate is movably installed on the inner wall of the raw coal bunker body. A feeding chute is opened on both sides of the lower end of the raw coal bunker body. Two guide plates are fixedly connected to both sides of the raw coal bunker body. A gate plate is slidably connected between the two guide plates. A toothed plate is fixedly connected to the end of the gate plate. A transmission gear is meshed with the lower end of the toothed plate.

The feeding assembly includes a clamping plate installed at the lower end of the support mechanism, two drive rollers rotatably connected between the two clamping plates, a drive belt provided on the side surface of the two drive rollers, and a plow plate movably installed on the upper end of the drive belt.

[0005] As a preferred embodiment of this utility model, the support mechanism includes two support plates, each with a limiting groove at its upper end. An installation ring is fitted onto the side surface of the raw coal bunker body, and an installation plate is fixedly connected to the side surface of the installation ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. When used in a raw coal bunker, the bunker body can be divided by the internal partition plate to facilitate the separate storage of bituminous coal and lean coal. During feeding, only one of the transmission mechanisms needs to be started simultaneously. The servo motor drives the second synchronous pulley to rotate, which in turn drives the first synchronous pulley to rotate. This, in turn, drives the transmission shaft and the transmission gears on its surface to rotate, causing the toothed plates and the gate plates to move closer or further apart along the guide plate. This seals or feeds the material into the feeding chute. Compared with the raw coal bunker in the existing technology "Anti-clogging Compartmentalized Raw Coal Bunker", this utility model, through the above-mentioned structure, can facilitate the separate storage of coal of different qualities and avoid clogging, thereby enhancing the practicality of the raw coal bunker. 2. When conveying raw coal, simply start the external transmission device to rotate the transmission roller, which in turn drives the transmission belt. As the transmission belt rotates, the raw coal can be automatically conveyed. At the same time, the plow plate can separate and convey the raw coal. Compared with the raw coal silo structure in the existing technology "Anti-blocking compartmentalized raw coal silo", this utility model can facilitate the automatic conveying of raw coal through the cooperation of the above structures, thereby improving the ease of use of the raw coal silo.

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.

[0018] Example 1 Please see Figures 1-5 This utility model provides a blockage-resistant compartmentalized raw coal silo, including a compartmentalized component 100 and a feeding component 200; The compartment component 100 includes a support mechanism 101, inside which a raw coal silo body 102 is installed. A partition plate 103 is movably installed on the inner wall of the raw coal silo body 102. A discharge chute 104 is opened on both sides of the lower end of the raw coal silo body 102. Two guide plates 105 are fixedly connected to both sides of the raw coal silo body 102. A gate plate 106 is slidably connected between the two guide plates 105. A toothed plate 107 is fixedly connected to the end of the gate plate 106. A transmission gear 108 is meshed with the lower end of the toothed plate 107. A transmission shaft 109 is fixedly connected inside the transmission gear 108. A transmission mechanism 110 is installed at one end of the transmission shaft 109. The feeding assembly 200 includes a clamping plate 201 installed at the lower end of the support mechanism 101. Two transmission rollers 202 are rotatably connected between the two clamping plates 201. A transmission belt 203 is provided on the side surface of the two transmission rollers 202. A plow plate 204 is movably installed on the upper end of the transmission belt 203.

[0019] In one specific embodiment, the compartmenting component 100, in conjunction with the feeding component 200, facilitates the separate storage of bituminous coal and lean coal, while also enabling automatic unloading and preventing blockages, thereby enhancing the practicality of the raw coal silo. Furthermore, the combined structure facilitates automatic separation and conveying of raw coal, further improving the ease of use of the raw coal silo. In use, the silo body 102 is first divided by the partition plate 103, allowing for separate storage of bituminous coal and lean coal. During unloading, only one of the transmission mechanisms 110 needs to be activated simultaneously, via the servo motor 1... 102 drives the second synchronous pulley 1103 to rotate, which in turn drives the first synchronous pulley 1101 to rotate with the synchronous belt 1104. This, in turn, drives the drive shaft 109 and the drive gear 108 on its surface to rotate. This allows the toothed plate 107 to move closer to or further away from the gate plate 106 along the guide plate 105, thereby sealing or discharging the feed chute 104. At the same time, the external transmission device is activated to drive the drive roller 202 to rotate, which in turn drives the drive belt 203 to rotate for automatic conveying of raw coal. Meanwhile, the plow plate 204 can separate and convey the raw coal, thereby improving the ease of use of the raw coal bunker.

[0020] Please see Figures 2-4 The support mechanism 101 includes two support plates 1011, and each of the two support plates 1011 has a limit groove 1012 at its upper end.

The installation plate 1014 is installed inside the limit groove 1012.

[0021] In one specific embodiment, the support plate 1011, in conjunction with the mounting ring 1013, can improve the installation stability and ease of disassembly and replacement of the raw coal bunker body 102. At the same time, the mounting ring 1013 can be disassembled by removing the mounting plate 1014 from the limiting groove 1012.

[0022] Please see Figures 2-4 The transmission mechanism 110 includes a first synchronous pulley 1101 installed at one end of the transmission shaft 109, a servo motor 1102 installed at the lower end of the support mechanism 101, a second synchronous pulley 1103 installed at the output end of the servo motor 1102, and a synchronous belt 1104 connecting the second synchronous pulley 1103 and the first synchronous pulley 1101.

[0024] Please see Figures 2-4 Both guide plates 105 have ear blocks 111 fixedly connected to their lower ends, and both ends of the drive shaft 109 are rotatably connected to the inside of the ear blocks 111.

[0025] In one specific embodiment, the ear block 111 can enhance the rotational connection stability of the drive shaft 109, thereby improving the rotational smoothness of the drive gear 108.

[0026] Please see Figures 2-4 The two guide plates 105 are provided with guide grooves 121 on their opposite sides, and guide blocks 122 are fixedly connected to both sides of the gate plate 106. The guide blocks 122 are slidably connected inside the guide grooves 121.

[0027] In one specific embodiment, when the gate 106 moves, the guide block 122 moves along the guide groove 121, thereby improving the smoothness of the movement of the gate 106.

[0028] Please see Figures 2-4 The inner walls of the limiting groove 1012 are provided with positioning grooves 131 on both sides. Two positioning blocks 132 are fixedly connected to both ends of the mounting plate 1014, and the two positioning blocks 132 are snapped into the inside of the positioning groove 131.

[0029] In one specific embodiment, the positioning block 132 is snapped into the positioning groove 131, which can significantly improve the stability of the mounting plate 1014 installed in the limiting groove 1012 and the ease of disassembly and replacement.

[0030] Please see Figures 2-4 The surfaces of the two support plates 1011 are provided with guide grooves 141, and the toothed plate 107 is slidably connected inside the guide grooves 141.

[0031] In one specific embodiment, the guide groove 141 can enhance the guiding and limiting effect on the toothed plate 107, thereby improving the smoothness of the reciprocating motion of the gate 106.

[0032] Please see Figures 2-4 The inner wall of the raw coal bunker body 102 is provided with a partition groove 151, and the partition plate 103 is snapped into the interior of the partition groove 151.

[0033] In one specific embodiment, the partition groove 151 can not only install and position the partition plate 103, but also improve the ease of disassembly and replacement of the partition plate 103.

[0034] Please see Figures 2-5 The lower ends of the two support plates 1011 are fixedly connected to L-shaped plates 161, and the L-shaped plates 161 and the clamping plates 201 are fixed together.

[0035] In one specific embodiment, the L-shaped plate 161 can enhance the connection strength between the support plate 1011 and the L-shaped plate 161, so as to ensure the installation stability of the clamping plate 201 and thus improve the safety of use.

[0036] Please see Figure 5 The upper ends of the two clamping plates 201 are fixedly connected to vertical plates 211. The surface of the vertical plates 211 is provided with slots 212. The back of the plow plate 204 is fixedly connected to a strip 213, which is engaged inside the slot 212.

[0037] In one specific embodiment, the clip 213 is snapped into the slot 212, thereby significantly improving the ease of disassembly and replacement between the plow plate 204 and the clamping plate 201.

[0038] Working principle: In use, the raw coal silo body 102 is first divided by the partition plate 103 to store bituminous coal and lean coal separately. During feeding, one of the transmission mechanisms 110 is started simultaneously. The servo motor 1102 drives the second synchronous pulley 1103 to rotate, which in turn drives the first synchronous pulley 1101 to rotate with the synchronous belt 1104. This drives the transmission shaft 109 and its surface transmission gear 108 to rotate, which in turn controls the toothed plate 107 to move closer or further away from the gate plate 106 along the guide plate 105. This allows for sealing or feeding operations on the feeding chute 104. Finally, the external transmission device is started to drive the transmission roller 202 to rotate, which in turn drives the transmission belt 203 to automatically convey the raw coal. At the same time, the coal plow plate 204 can separate and convey the raw coal, thus improving the ease of use of the raw coal silo.
