Waste coal slag smashing device for power plant

Abstract

The invention discloses a waste coal slag smashing device for a power plant. The waste coal slag smashing device comprises an outer shell. Two hydraulic cylinders are symmetrically and fixedly installed on the outer side wall of the upper portion of the outer shell; piston rods of the hydraulic cylinders penetrate through the side walls of the outer shell, extrusion plates are fixedly installed onthe piston rods of the hydraulic cylinders, and smashing teeth are arranged on the extrusion plates; output shafts of first motors penetrate through the side walls of the outer shell, and a turning-over plate is fixedly installed on the output shafts of the first motors through pin shafts and bearings; two second motors are fixedly installed on the outer side wall of the middle of the outer shell, output shafts of the second motors are in transmission connection with roller shafts through couplers, smashing rollers are arranged on the roller shafts, and hemispherical protruding blocks are arranged on the smashing rollers; and a filter net plate is erected on erecting plates. The smashing efficiency is high, the smashing precision of waste coal slag is improved, the fine waste coal slag meeting the requirement can be screened out, thus the screening speed is high, and the screening effect is good.

Description

technical field [0001] The invention relates to the technical field of waste coal slag, in particular to a waste coal slag crushing device for power plants. Background technique [0002] Coal slag, a kind of industrial solid waste, is also called slag, which is discharged from coal burning in thermal power plants, industrial and civil boilers and other equipment. The main components are silica, alumina, iron oxide, calcium oxide, magnesium oxide, etc. Depending on the composition, it can be used to make cement, bricks and refractory materials, etc. Some can be used to produce alumina or to extract rare metals such as gallium and germanium. [0003] The cinder crushing device is also called cinder crusher. It uses gangue and coal slag as additives and internal fuel for brick factories. Using gangue and shale to produce standard bricks and hollow bricks is a major measure that conforms to national policies and benefits the society. However, the crushing of these materials h...

AI Technical Summary

Problems solved by technology

[0004] The existing coal cinder crushing device has the disadvantages of incomplete crushing, poor crushing effect, and poor precision, and does not have the screening function after crushing, and needs to use another screening device for screening, which is time-consuming and laborious
