Problems solved by technology

[0004] The purpose of the present invention is to solve the problems in the prior art. During the use of the pre-crushing device for coal burning in industrial boilers, after the breaker has crushed the coal many times, the surface of the breaker is likely to stick to a large amount of coal. The waste of coal resources, manual cleaning is time-consuming and laborious, and it is easy to be stabbed by the crushing nails on the crushing hammer. The crushing hammer often adopts the impact crushing method, which has a poor crushing effect and cannot meet the requirements of coal crushing. problems, and proposed a pre-crushing device that facilitates the combustion of industrial boiler coal

Abstract

The invention discloses a pre-crushing device convenient for combustion of industrial boiler coal briquettes, which comprises a supporting seat, a fixed shell is fixedly mounted at the upper end of the supporting seat, a crushing hammer is arranged on the lower side in the fixed shell, a fixed column is fixedly connected to the middle of the upper end of the crushing hammer, a connecting rod I is fixedly connected to the upper side of the left end of the fixed column, and a ball is fixedly mounted at the left end of the connecting rod I; a spiral groove is formed in the position, corresponding to the ball, of the inner wall of the fixing shell, the ball is slidably connected with the inner wall of the fixing shell, a crushing box is arranged at the position, located on the lower side of the crushing hammer, of the upper end of the supporting base, a plurality of crushing nail plates are arranged on the outer side of the crushing hammer, and second connecting rods are fixedly installed at the ends, close to the middle of the crushing hammer, of the crushing nail plates. And the hydraulic cylinder is started to drive the fixing seat to descend, the fixing seat drives the fixing column to descend, and the fixing column drives the crushing hammer to descend, so that the coal briquettes in the crushing box are conveniently extruded and crushed, the pre-crushing of the coal briquettes is realized, and the subsequent combustion utilization rate of the coal briquettes is improved.

Description

technical field [0001] The invention relates to the technical field of industrial boilers, in particular to a pre-crushing device that facilitates the combustion of coal lumps in industrial boilers. Background technique [0002] There are two types of industrial boiler products. One is steam, which is used for power generation or gas supply. For example, chemical fertilizer plants can use steam to vaporize, use coal as raw material, and synthesize chemical fertilizers. This is a typical industrial boiler. Most, gas-fired generally waste heat boilers are used to recover waste heat. The common industrial boiler is the circulating fluidized bed boiler. Industrial boiler is an important thermal power equipment. my country is the country with the most boiler production and use in the world today. China's manufacturing industry was established and developed after the founding of New China. [0003] In the prior art, when the pre-crushing device for burning coal lumps in an indus...
