Description

Technical Field

[0001] The utility model relates to the technical field of coal conveying equipment, in particular to a coal bunker with a divided bunker structure. Background Art

[0002] At present, in order to meet the requirements of electricity market regulation and ensure the fundamental interests of power plants, the units need to have deep peak-shaving capabilities to meet electricity demand in different periods. Since the combustion capacity and price difference of different coal qualities are quite different, in order to save costs, low-quality coal or a mixture of good and bad coal is generally used for production during low-peak or flat-peak periods, and high-quality coal is used for production during peak electricity consumption periods. However, the existing coal bunkers can only use one type of coal quality for production and cannot be flexibly converted. If it is necessary to switch to high-quality coal during peak electricity consumption, the coal quality needs to be converted, which will consume a lot of manpower and material resources, which not only increases costs but also reduces work efficiency.

[0003] In the prior art, partitions are usually set in the middle of the coal bunker to separate the internal space of the coal bunker, so as to achieve the purpose of storing coal of different qualities separately; for example, a coal bunker with a sub-bin structure with publication number CN219858614U realizes the separation of the internal space of the coal bunker by setting a partition plate, thereby dividing the internal space of the coal bunker body into two, so as to meet the supply demand for high-quality coal during peak load of the operating units; although this method solves the problem of internal separation of the coal bunker, due to the reduction of the internal space of the coal bunker, coal is easily accumulated and blocked in the coal bunker, which has an adverse effect on the smooth falling of the coal and affects the smooth progress of subsequent work. Utility Model Content

[0004] The purpose of the utility model is to provide a coal bunker with a compartment structure, which can not only carry out compartment transformation on the coal bunker body, but also divide the internal space of the coal bunker body into two parts, so as to realize the differentiated storage of high-quality coal and low-quality coal, and also can loosen the coal stored in the coal bunker body to prevent the coal from accumulating and clogging; and make the coal fall normally during the work process to ensure the work efficiency.

[0005] The utility model adopts the following technical solutions:

[0021] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:

[0022] like Figures 1 to 4 As shown, a coal bunker with a compartment structure described in the utility model comprises a coal bunker body 1, a partition plate 2 is arranged in the middle of the coal bunker body 1 in the vertical direction, the shape of the partition plate 2 matches the shape of the coal bunker body 1, and the two ends in the horizontal direction are tightly connected to the inner wall of the coal bunker body 1, and a plurality of driving rods 3 are arranged in parallel in the horizontal direction on the partition plate 2, each driving rod 3 can move up and down in the vertical direction, and the driving rod 3 is driven by a power device, and each driving rod 3 is hinged with an evacuation rod 4, which is located on both sides of the driving rod 3, and its ends away from one end are movably passed through the two sides of the partition plate 2. The evacuation rod 4 can collide with the falling coal to break up the falling coal, and can also extend into the coal in layers in the vertical direction to prevent the coal from being too densely piled up and blocking; at the same time, when unloading, the driving rod 3 can be controlled to move up and down to drive the evacuation rod 4 to move up and down, so as to disturb the coal and further prevent the coal from accumulating and blocking.

[0023] Furthermore, the partition plate 2 is provided with a plurality of vertical installation grooves at intervals along the radial direction of the coal bunker body 1, and a support sleeve 5 is installed in each installation groove, and the support sleeve 5 is detachably connected to the partition plate 2, wherein the support sleeve 5 is made of high-strength steel plate, and the driving rod 3 is slidably arranged on the support sleeve 5, and the support sleeve 5 is provided with a through hole for the evacuation rod 4 to move through. Specifically, one end of the evacuation rod 4 is hinged to the driving rod 3, and the part located in the through hole is hinged to the inner wall of the through hole, so that as the driving rod 3 moves up and down, the evacuation rod 4 is driven to move up and down along the hinge point, thereby realizing the loosening operation of the coal material. In addition, in this embodiment, a connection plate 6 is commonly provided at the top of a plurality of driving rods 3, and the power equipment is connected to the connection plate 6, so as to realize the synchronous adjustment of a plurality of evacuation rods 4; guide plates 7 are preferably provided obliquely on both sides of the connection plate 6, and the guide plates 7 can provide guidance for the coal material falling into the coal bunker body 1. Among them, the evacuation rod 4 is a regular triangular prism structure with an upward edge, which can not only ensure its structural strength, but also use its upward edge to collide with the falling coal, so that the coal is broken up and falls. At the same time, the inclined surfaces on both sides of the edge of the evacuation rod 4 can also be used to provide guidance for the falling coal. When loosening the coal, the upward movement of the evacuation rod 4 can also be controlled first to reduce the resistance encountered by the evacuation rod 4 when loosening the coal.

[0024] Furthermore, both sides of the evacuation rod 4 are provided with a disturbance rod 8 with a pointed end to increase the disturbance of the coal when the evacuation rod 4 moves, further break up the coal, and reduce the probability of coal accumulation and blockage. In addition, in this embodiment, a reinforcement rod 9 perpendicular to the support sleeve 5 is also provided on the partition plate 2 to enhance the ability of the partition plate 2 to resist the lateral pressure, and to avoid the deformation of the partition plate 2 due to pressure imbalance when the materials on both sides of the coal bunker body 1 are different; wherein the reinforcement rod 9 is also a regular triangular prism structure, and the ridge line faces the side away from the partition plate 2, so as to enhance the structural strength while reducing the probability of part of the coal accumulating on the reinforcement rod 9 after the coal falls; preferably, the reinforcement rod 9 is located at the evacuation rod 4, and a through hole is opened on the reinforcement rod 9 for the evacuation rod 4 to move through.

[0025] Further, a driving ring 10 is rotatably provided at the top of the coal bunker body 1, and the driving ring 10 is coaxially arranged with the coal bunker body 1. A scraper 11 is arranged inside the driving ring 10, and the shape of the scraper 11 matches the structure of the coal bunker body 1; a gear ring 12 is arranged outside the driving ring 10, and a driving motor 13 is arranged on the coal bunker body 1, and a driving gear 14 meshing with the gear ring 12 is arranged on the driving motor 13. When working, the gear ring 12 can be driven to rotate under the action of the driving motor 13, thereby driving the driving ring 10 to rotate, thereby driving the scraper 11 to move, and realizing the cleaning operation inside the coal bunker body 1; since the inner wall of the coal bunker body 1 is divided into two cavities, a rear scraper 11 is arranged in each cavity, and in the initial state, the two scrapers 11 are located at the diagonal positions of the partition plate 2, so as to complete the cleaning operation of the inner wall of the coal bunker body 1 by controlling the forward and reverse rotation of the driving motor 13, and avoid the situation where coal material accumulates and adheres to the inner wall of the coal bunker, causing the internal space of the coal bunker body 1 to be reduced, and even blocking the coal bunker body 1.

[0026] In addition, a cover plate 15 is rotatably arranged on the driving ring 10, and two discharge ports 16 which are connected to the material conveying pipeline are arranged on the cover plate 15, which are respectively connected to the high-quality coal conveying channel and the low-quality coal conveying channel; after the cover plate 15 is connected to the material conveying pipeline, it is in a fixed state. During operation, the driving ring 10 rotates relative to the coal bunker body 1 and the cover plate 15; the power equipment is an oil cylinder 19 arranged on the cover plate 15, and the working end of the oil cylinder 19 is located at the bottom of the cover plate 15 and is connected to the connecting plate 6. The up and down movement of the driving rod 3 can be controlled by the extension and retraction of the oil cylinder 19, thereby driving the evacuation rod 4 to move up and down, so as to move the accumulated coal material to prevent it from accumulating and clogging inside the coal bunker body 1. Among them, the drive ring 10, the cover plate 15 and the coal bunker body 1 are preferably connected through a slewing bearing. In order to prevent the coal from damaging the slewing bearing and prevent the material from entering the slewing bearing, the utility model also provides two aramid packings at the flange connections between the slewing bearing and the drive ring 10 and the cover plate 15 to improve the sealing effect.

[0027] In this embodiment, an electro-hydraulic bidirectional gate 17 is also provided at the bottom of the coal bunker body 1, which is used to realize the operation of opening and closing the space containing low-quality coal or high-quality coal separately, thereby improving the convenience of operation. Since the bottom diameter of the coal bunker body 1 is small and the material unloading space is shrunk, an air hammer 18 can be arranged on the outer periphery of the bottom of the coal bunker body 1 to assist in unloading, thereby ensuring the smooth progress of the work.

[0028] When the utility model is in use, the conveying operation of coal of different qualities into the coal bunker body 1 is completed through the conveying pipeline connected to the feed port on the cover plate 15; after the conveying is completed, the frequency of the driving rod 3 activity can be controlled according to the humidity of the coal to prevent the coal from accumulating and agglomerating when stored in the coal bunker body 1. When unloading is required, the electro-hydraulic two-way plug-in door 17 can be controlled to open in a targeted manner. The utility model is easy to operate, simple in structure and highly practical.
