Abstract

The invention discloses a pebble coal discharge mechanism of a coal mill, in particular a pebble coal sealing discharge device. It includes a pebble coal drop port and a sealing box, the pebble coal drop port and the seal box are connected together through a conveying pipeline, a primary shut-off valve and a secondary shut-off valve are set on the pipeline, and a storage and transportation bin is set at the lower end of the sealing device, and the storage and transportation small The lower end of the warehouse is equipped with a weighing device, and the outlet of the lower end of the sealed box is connected with a telescopic joint. The sealed box is also provided with a cylinder to control the telescopic movement of the telescopic joint. The edge of the material inlet is in sealing contact. After adopting the above-mentioned structure, the entire slag discharge process can be carried out under completely closed conditions to avoid dust and powder spraying; using a sealed slag discharge device plus negative pressure and water spraying treatment can further eliminate dust and coal gangue spontaneous combustion Occurrence; At the same time, load-bearing sensors are installed to completely avoid the accumulation of pebbles and coal. Dumping by special forklifts does not require manual handling and reduces labor output.

Description

[0001] technical field [0002] The invention relates to a pebble coal discharge mechanism of a coal mill, in particular to a pebble coal sealing discharge device. Background technique [0003] In thermal power generation enterprises, medium-speed mills are widely used in generating units above 300,000 kilowatts. In the medium-speed mill systems currently in operation in my country, pebble coal discharge is always the largest source of dust pollution in coal mill workshops, seriously interfering with In the civilized production of power plants, most of the pebble coal discharge devices in the prior art still adopt direct open discharge. Since the pebble coal contains dust and coal powder, the dust on the site is flying during the slag discharge and transfer discharge process, which has serious damage to the field equipment and the working environment. hazards, causing on-site environmental pollution, affecting the environmental sanitation of the factory area, and also causing ...
