Description

Technical Field

[0001] The utility model is a device for distributing materials in a slag inlet pipe of a chain bucket conveyor of bottom slag conveying equipment used in a circulating fluidized bed unit power plant, in particular to a novel material distributing device for a chain bucket conveyor. Background Art

[0002] At present, when the chain bucket conveyor is running, the materials need to enter it through the feed pipe, and the materials fall into the chain bucket conveyor hopper. The width of the hopper is mostly 1 meter. The materials falling into the chain bucket have more on one end and less on the other end, which will cause uneven force on both sides of the chain bucket conveyor when it is running, causing unilateral wear and affecting the life of the chain, roller and track. Therefore, it is particularly important to evenly distribute the materials on the hopper and maintain a good force state.

[0003] Specifically, the feed pipes of the chain bucket conveyors currently used in power plants are all configured with a single 300mm×300mm or 400mm×400mm steel pipe, which is set in the middle of the chain bucket conveyor casing. The chain bucket conveyor is usually one in use and one in reserve. One boiler is set with two lines, which are set at the bottom of the upstream equipment slag cooler, and arranged on both sides of the center line with the outlet of the slag cooler as the center line, thus forming a one-in and two-out structure. The slag feed pipe connected to the inlet of each chain bucket conveyor is an inclined pipe. The inclined pipe is different from the straight pipe when feeding. The material ash slides along the inclined pipe, resulting in an oblique conveying to one side. After entering the chain bucket conveyor, the material accumulates on one side, which is difficult to adjust, causing unilateral accumulation of the material. Then the side with more material will cause greater downward pressure on the chain, sprocket and guide rail, resulting in eccentric wear of parts on one side. Therefore, it is urgent to design a new type of chain bucket conveyor material distribution device to solve this problem. Utility Model Content
