Novel coal feeder iron removing device for thermal power plant

Abstract

The invention discloses a novel coal feeder iron removing device for a thermal power plant and relates to the technical field of iron removing devices. The novel coal feeder iron removing device for the thermal power plant comprises a base plate. The top of the base plate is fixedly connected with a work frame. The two sides of the inner wall of the work frame are fixedly connected with feeding pipes. The two sides of the inner wall of the work frame are both fixedly connected with moving guide plates. The sides, far away from the work frame, the moving guide plates are movably connected witha horizontal screen plate. The bottom of the inner wall of the work frame is fixedly connected with a screening motor frame. According to the novel coal feeder iron removing device for the thermal power plant, by means of combined arrangement of a static plate, a gravity crushing disk, pressing nails, a grinding motor box, a grinding motor and a driving shaft, coal blocks can be further grinded and crushed in the device by the pressing nails at the bottom of the gravity crushing disk, so that the coal block smashing degree is further improved, the operation reliability of the novel coal feederiron removing device for the thermal power plant is greatly improved, it is guaranteed that the novel coal feeder iron removing device can attract small iron fragments out of a coal pile, and the novel coal feeder iron removing device is simple in overall structure.

Description

technical field [0001] The invention relates to the technical field of iron removal devices, in particular to a new type of iron removal device for coal feeders used in thermal power plants. Background technique [0002] A thermal power plant is a thermal power plant that uses the extraction or exhaust steam of a steam turbine to provide heat for users while generating electricity. General power plants use condensing units, which only produce electricity to supply power to users. The heat for industrial production and people's life is supplied separately by the special industrial boiler and heating boiler room. This energy production method is called heat and electricity division. In thermal power plants, heating units are used, in addition to supplying electrical energy, steam turbine extraction or exhaust steam is used for overwork (ie power generation) to meet the heat required for production and life. This method of energy production is called cogeneration. In the po...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a new type of iron removal device for coal feeders used in thermal power plants, which solves the problem of long-distance transportation and accumulation of coal in thermal power plants. There are small iron materials such as iron sheets and screws. When these iron materials are mixed with coal during combustion, the combustion efficiency will be seriously affected, which is not conducive to the comprehensive combustion of coal in thermal power plants.
