Description

Raw coal bunker of coal motor group with dividing bunker structure Technical Field The utility model relates to the technical field of coal conveying equipment, in particular to a raw coal bin of a coal motor group with a bin dividing structure. Background In order to meet the regulation and control requirements of the electric power market and ensure the fundamental benefit of a power plant, a unit needs to have deep peak regulation capability to meet the electricity consumption requirements of different periods, and because the combustion capability and price difference of different coals are greatly different, in order to save the cost, the low-grade coal or the good-grade coal is generally adopted for production in the low-grade or flat-grade period of electricity consumption, the high-grade coal is generally adopted for production in the high-grade period of electricity consumption, and in the prior art, a partition plate is generally arranged in the middle of a coal bunker to realize the separation of the inner space of the coal bunker so as to achieve the purpose of respectively storing the coals with different qualities. However, in actual operation, the problems of unbalanced coal level and uneven load exist, and the coal level heights at the two sides of the partition plate are difficult to be kept consistent due to different coal discharge amounts of high-quality coal and low-quality coal, so that the stress at the two sides of the partition plate is uneven. Under long-term operation, the baffle can produce deformation and even structural damage because of unilateral coal pressure is too big, influences the overall stability of coal bunker. After the partition plate is deformed, an effective coal storage space of the coal bin can be extruded, so that the fluidity of coal is reduced, blockage is easily formed near a coal discharge port, continuous transportation of fire coal is affected, the maintenance cost of equipment can be increased due to frequent correction or replacement of the partition plate, and meanwhile, the operation efficiency of a unit can be reduced due to shutdown overhaul caused by blockage of the coal bin. Therefore, a raw coal bin of the coal motor unit with a bin division structure is needed to improve the deformation resistance of the partition plate and the operation reliability of the coal bin while ensuring the separation function of the coal bin. Disclosure of utility model The utility model aims to provide a raw coal bin of a coal motor group with a bin separation structure, which can ensure the separation function of the coal bins, improve the deformation resistance of a baffle plate and the operation reliability of the coal bins and ensure the working efficiency. The utility model adopts the following technical scheme: The raw coal bin of the coal motor unit with the bin dividing structure comprises a coal bin body, wherein a separation part is arranged in the coal bin body along the vertical direction, the inside of the coal bin body is separated into two storage cavities through the separation part, the separation part consists of two symmetrically arranged partition plates, and the two partition plates are of an outwards convex arc-shaped structure. Preferably, a supporting frame is arranged between the two partition boards. Preferably, the support frame comprises a middle main support, two ends of the main support are abutted against the inner walls of the two opposite partition plates, inclined supports are arranged on the main support, and the inclined supports are abutted against the inner walls of the partition plates on two sides of the main support. Preferably, the diagonal brace is provided with an arc plate matched with the side wall of the partition plate. Preferably, the two ends of the main support are respectively provided with a screw, the partition plate is provided with a screw hole, and the screw is provided with a nut after penetrating out of the screw hole. Preferably, the partition plate is provided with a plurality of reinforcing ribs at intervals from top to bottom. Preferably, each main support is provided with two groups of diagonal braces, and the two groups of diagonal braces are distributed on two sides of the axis of the main support. Preferably, the main support and the diagonal support are integrally formed. Preferably, the two sides of the partition board are provided with connecting plates. Preferably, the connecting plate and the partition plate are integrally formed. Compared with the prior art, the coal bunker has the beneficial effects that the partition board with the convex arc-shaped structure is arranged in the coal bunker body, so that the lateral pressure of coal can be converted into the dispersed stress along the arc surface of the partition board, the stress is more uniform, the local stress concentration is avoided, the deformation resistance of the partition board is greatly improved, and the service life is prolonged.
