Coarse and fine separation device for coal conveying of combustion system of power plant

Abstract

The invention discloses a coarse and fine separation device for coal conveying of a combustion system of a power plant. The coarse and fine separation device comprises an installation base, a separation device, a dredging device and positioning devices. According to the coarse and fine separation device, the separation device is arranged in the installation base, a separation plate is arranged inside the separation device and is provided with electric push rods, the separation plate is rotationally connected with the inner wall of the separation device, so that an user can effectively meet therequirement for the thickness degree of the coal body of the combustion system of the power plant, the electric push rods are adjusted through a controller, so that the separation device can effectively separate and process the coal body on a conveying belt of the combustion system of the power plant through the separating plate, meanwhile, the dredging device are arranged in the installation base, guide plates are arranged on the two sides of a partition board inside the dredging device through a guide shaft, the deviation angle of the guide plates is controlled through a rotating handle toadjust, so that the separated coal body can further realize the separation effect, and the coal body combustion efficiency can be maximized while the energy is saved by the conveyed coal body.

Description

technical field [0001] The invention relates to the technical field of separation devices, in particular to a coarse and fine separation device for coal transportation in a combustion system of a power plant. Background technique [0002] A power plant, also known as a power station, is a factory that converts various primary energy sources stored in nature into electrical energy. A thermal power plant, referred to as a thermal power plant, is a factory that uses combustibles as fuel to produce electrical energy. Its basic production process is: the fuel is heated when it is burned Water generates steam, which converts the chemical energy of the fuel into thermal energy. The steam pressure drives the steam turbine to rotate, and the thermal energy is converted into mechanical energy. Then the steam turbine drives the generator to rotate, and converts the mechanical energy into electrical energy. Power stations may also use internal combustion engines, which generate electric...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the coal transported by the combustion system of a power plant has not been effectively separated and screened during combustion, so that the coal in the combustion system cannot effectively achieve the maximum combustion rate of the coal during combustion, thereby greatly reducing The combustion effect of the coal body is reduced, and precious natural resources are further wasted, so it cannot meet the needs of the existing technology
