Automatic bin cleaning anti-blocking device for raw coal bin of thermal power plant

Abstract

The invention discloses an automatic cleaning and anti-blocking device for a raw coal bunker of a thermal power plant, which comprises a base, a supporting seat is arranged at the upper end of the base, a collecting bin is connected to the inner wall of the base, a discharge pipe is arranged at the lower end of the collecting bin, a controller is arranged at the upper end of the base, and the automatic cleaning and anti-blocking device comprises a push shovel mechanism, an auxiliary mechanism, a drying mechanism and a scraping mechanism; the push shovel mechanism is used for pushing away the raw coal blocking the discharging pipe; the push shovel mechanism pokes the raw coal blocked in the discharging pipe, the auxiliary mechanism assists the push shovel mechanism in loosening the raw coal blocked in the discharging pipe, the removing function of the push shovel mechanism is improved, the dredging efficiency of the discharging pipe is improved, the discharging pipe is heated through the drying mechanism, the blocked raw coal is dried, the raw coal is not prone to adhering to the discharging pipe, and therefore the raw coal discharging efficiency is improved. And the scraping mechanism is used for scraping the raw coal adhered to the inner wall of the discharging pipe, so that the actual caliber of the discharging pipe is enlarged, and the situation that the discharging pipe is blocked is reduced.

Description

technical field [0001] The invention relates to an anti-blocking device for clearing a raw coal warehouse. Background technique [0002] Thermal power plants, referred to as thermal power plants, are factories that use combustibles as fuel to produce electricity. Its basic production process is: when the fuel is burned, it heats water to generate steam, which converts the chemical energy of the fuel into heat energy, the steam pressure drives the steam turbine to rotate, and the heat energy is converted into mechanical energy, and then the steam turbine drives the generator to rotate, converting the mechanical energy into electrical energy, and The combustible material used is generally coal. [0003] When the raw coal of the thermal power plant is discharged from the collection bin, the raw coal will be easily adhered to the inner wall of the outlet pipe of the collection bin due to the influence of moisture on the raw coal. It is discharged from the collection bin, and t...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the defect that the raw coal is easy to accumulate in the outlet pipe when the raw coal is cleared, and it is inconvenient to deal with the defect that the raw coal is accumulated in the outlet pipe to provide an automatic clearing and anti-blocking device for the raw coal bunker of the thermal power plant
