Bin device employing single-point feeding and parallel and uniform blanking

Abstract

The invention discloses a bin device employing single-point feeding and parallel and uniform blanking. The bin device comprises a charging barrel (C) and a hopper (D), wherein the hopper (D) is arranged at the bottom of the charging barrel (C); a feeding hole (A) of a bin is formed in the top of the charging barrel (C); a dust exhaust outlet (B) is arranged in the side of the feeding hole (A); a material binding plate for binding a material is arranged in the feeding hole (A), the material binding plate is provided with a sector section, and the material binding plate can swing left and right; a plurality of guide cylinders with openings in two ends, which are concentrically nested together, are arranged in the charging barrel (C), and the bottoms and tops of the plurality of guide cylinders are arranged in a staggered manner and are in ladder form; the center guide cylinder is the highest, and the heights of the other guide cylinders are gradually reduced; and a clock pendulum which is used for effectively and uniformly discharging the stored material out of the bin and is capable of swinging is arranged in a discharge hole of the hopper. According to the bin device employing single-point feeding and parallel and uniform blanking, an internal component is reasonably added to the bin, so that coal particles which fall into a feed coal bunker through single points are uniformly stored, and meanwhile, the flow velocity of center particles of the charging barrel is reduced.

Description

technical field [0001] The invention belongs to the fields of coal chemical industry and oil shale pyrolysis, and in particular relates to a silo device for single-point feeding and parallel and uniform feeding. Background technique [0002] The graded transformation of coal is of great significance to promote the transformation and upgrading of the coal industry and realize the clean and efficient utilization of coal, and coal pyrolysis is the technical core of coal quality utilization. Although there are many types of pyrolysis technology and key equipment, and there is a phenomenon of "a hundred flowers blooming", at present, the internal heating type vertical furnace process is mainly used for the industrial production of semi-coke (also known as semi-coke) in my country, which has a large scale of construction. , wide distribution area, strong adaptability of coal types, and long operation period. With the continuous development of my country's coal chemical industry, t...

Problems solved by technology

There are fine particles in the center of the top of the circular stockpile, and large particles around the conical bottom. From the raw material bin through the bottom conical outlet, the force of the inner wall of the cone makes the feeding speed of the particles close to the inner wall of the cone slower. The feeding speed in the central area is fast. Due to the small particle size in the central area, the particle size falling into the pyrolysis furnace is uneven, resulting in uneven void ratio, uneven air permeability, and uneven heating, resulting in uneven pyrolysis. Uniformity, which affects the product quality of pyrolysis semi-coke
