Description

Raw coal bin dividing structure capable of increasing peak regulation flexibility Technical Field The utility model relates to the technical field of coal conveying equipment, in particular to a raw coal bin dividing structure for increasing peak shaving flexibility. 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 power 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 power consumption, the high-grade coal is generally adopted for production in the high-grade period of power consumption, and in the prior art, a partition plate is generally arranged in the middle of a coal bin to separate the inner space of the coal bin so as to store the coals with different qualities in the same coal bin, thereby achieving the purpose of flexible peak regulation. However, in actual operation, the existing partition plate is usually an integrated steel plate, and is directly welded in the coal bunker to separate the inner space of the coal bunker, and the height of coal positions at two sides of the partition plate is difficult to be kept consistent due to different coal discharge amounts of high-quality coal and low-quality coal during working, so that the stress at two sides of the partition plate is uneven. Under long-term operation, the baffle can produce the condition of deformation and even structural damage because of unilateral coal pressure is too big, so need to carry out the whole change to the baffle and demolish, not only intensity of labour is big, and the long continuous transport that influences the fire coal of occupation time also can increase equipment maintenance cost. Therefore, a raw coal bin of the coal motor unit with a separated bin structure, which not only can improve stress intensity, but also is convenient for targeted replacement and maintenance, is needed. Disclosure of utility model The utility model aims to provide an original coal bunker separating structure for increasing peak shaving flexibility, which can not only improve the stress intensity of the separating structure in the coal bunker, but also realize targeted replacement in the subsequent damage, reduce the maintenance cost and maintenance difficulty, shorten the shutdown time and ensure the coal conveying efficiency through the modularized arrangement of a separating beam and a partition plate. The utility model adopts the following technical scheme: The raw coal bin dividing structure for increasing the peak regulation flexibility comprises a coal bin body, wherein a plurality of separation beams are arranged in the coal bin body at intervals along the vertical direction, each separation beam is arranged along the radial direction of the coal bin body, two ends of each separation beam are fixedly connected with the inner wall of the coal bin body, a partition plate is arranged between every two adjacent separation beams, and the inside of the coal bin body is divided into two storage spaces through the separation beams and the partition plates. Preferably, the separation beam is H-shaped steel. Preferably, two partition plates are symmetrically arranged between two adjacent partition beams, and the two partition plates are respectively positioned on the outer sides of the corresponding partition beams.
