Coal gangue dry-type slag cooling machine

Abstract

The dry coal gangue slag cooling machine includes feeding bin, cooling air inflow pipe, support frame, tracks, transferring chain, material tray, material tray support, driving motor, transmission gear, chain wheel, roller, water pipe, water collecting trough, water level regulator, limiter and chain regulator. Red and hot coal slag is made to be air and water cooled for relatively long time inside the water collecting trough with low abrasion coefficient. The present invention is an auxiliary machine for boiler and is used to complete cooling and transmission of coal slag and can utilize coal gangue resource and produce no environmental pollution.

Description

Technical field: [0001] The invention relates to a coal gangue dry-type slag cooling machine, which relates to the technical field of hot red material cooling and conveying machinery manufacturing, in particular to the technical field of circulating fluidized bed boiler auxiliary machine manufacturing technology with a large amount of hot red slag material. Background technique: [0002] In my country today, there is a huge amount of coal gangue piled up. Due to various reasons, it is difficult to use it. It not only wastes a lot of energy, but also invades the land and pollutes the environment. According to the data of the relevant state departments, the amount of coal gangue piled up in my country has reached 30 billion tons, occupying several thousand hectares of land, and is still increasing by 100 million tons every year. On the contrary, the comprehensive utilization rate is indeed less than 10% of the annual growth rate. [0003] At present, the domestic circulating fl...

[0002] In my country today, there is a huge amount of coal gangue piled up. Due to various reasons, it is difficult to use it. It not only wastes a lot of energy, but also invades the land and pollutes the environment. According to the data of the relevant state departments, the amount of coal gangue piled up in my country has reached 30 billion tons, occupying several thousand hectares of land, and is still increasing by 100 million tons every year. On the contrary, the comprehensive utilization rate is indeed less than 10% of the annual growth rate

[0003] At present, the domestic circulating fluidized bed boiler is a relatively good coal-fired furnace, and the use of coal gangue to generate electricity is gradually being implemented in my country. The in-situ cooling and transmission of a large amount of hot red coal slag after combustion has become a prominent problem, because the market The slag cooling machine that can be matched with circulating fluidized bed boilers, whether the cooling medium is water-cooled or air-cooled, and the slag discharge method is whether the rotary vane propulsion, rotary falling, steam tank wind blowing, etc., due to its limitations, the slag cooling The amount hovers around 10T / H, which cannot meet the needs of circulating fluidized bed boilers to generate electricity greater than 10T / H by burning coal gangue, or even nearly 100T / H. There is no corresponding equipment, which greatly affects the coal fired Resource Utilization of Gangue Power Generation
