A wood block separator

Abstract

The invention discloses a wood block separation and smashing device which comprises a box type machine frame, a pushing-movement separation machine and pressing smashing machines. The top of the box type machine frame is provided with a powder bin connecting pipe, and the bottom of the box type machine frame is provided with a mill connecting pipe. A separation grid is arranged in an inner cavity of the powder bin connecting pipe. A conical guide pipe and a wood block smashing bin are arranged at the bottom of an inner cavity of the box type machine frame. The pushing-movement separation machine is installed on the top of the inner cavity of the box type machine frame and comprises a winding drum rope puller, a shaft type support and a grid cleaning rod. The pressing smashing machines are arranged at the two ends of the wood block smashing bin respectively. Each pressing smashing machine comprises a telescopic jacking column and a rotary fluted disc. The box type machine frame and a ball mill coal powder pipe are connected into a whole, wood blocks are separated out of coal powder through the separation grid and ground into powder through the pressing smashing machine, the ground wood blocks together with the coal powder are fed into a boiler to be combusted, and the phenomena such as gas leakage and powder leakage affecting normal production of a power making system are avoided. Accordingly, the wood block separation and smashing device is reasonable in structure, easy to operate and control, and capable of improving production efficiency.

Description

technical field [0001] The invention belongs to a shredder, in particular to a wood block separating shredder. Background technique [0002] In coal-fired power plants, a drum coal mill is often used to grind coal into powder, and then send the coal powder into the boiler for combustion. The coal mill can conveniently grind the coal into powder, but the wood mixed in the coal powder However, there is no way to crush the lumps. For this reason, a wood separation device is provided in the coal pulverized pipe of the coal mill to prevent the wood from entering the pulverized coal bin and causing pipeline blockage. The prior art wood block separation device can only separate the wood blocks from the coal powder into the wood block storage bin. However, during the process of taking out the wood block from the wood block storage bin, air leakage and powder leakage often occur and affect the pulverization system. normal production conditions.

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem of easy air leakage and powder leakage in the prior art wood block separation device, the present invention aims to provide a wood block separation shredder, which is equipped with a pushing separator and a top pressure shredder, which can not only crush wood The block can be easily separated from the coal powder, and the wood block can be ground into powder and enter the coal powder bin together with the coal powder, which will not affect the normal production of the pulverization system.
