A tubular wood block separating cutter

Abstract

A tubular wood block separation cutter comprises a tubular box body, a collection plate turnover machine, an isolation plate turnover machine and a screen type cutting machine; a wood block box bin is arranged in the middle portion of an inner cavity of the tubular box body, the collection plate turnover machine comprises a lower plate turnover mechanism and a lower turnover grid plate and is mounted on the top of the tubular box body, and the isolation plate turnover machine comprises an upper plate turnover mechanism and an upper turnover grid plate and is mounted at the bottom of the tubular box body; the screen type cutting machine comprises a multi-axis seat roller rack, a fret saw roller and a linear wood saw and is mounted at the bottom of the wood block box bin; the tubular box body and a ball grinding mill pulverized coal pipe are connected into a whole, wood blocks in pulverized coal are separated out through the collection plate turnover machine and are loaded into the wood block box bin, the screen type cutting machine cuts the wood blocks into small particles, the small particles and pulverized coal are mixed together and are fed into a boiler to be combusted, and the condition that leaked gas, leaked pulverized coal and the like affect normal production of a pulverized coal making system is avoided; and thus, the tubular wood block separation cutter is reasonable in structure, easy to operate and control and capable of improving production efficiency.

Description

technical field [0001] The invention belongs to a wood block separator, in particular to a tubular wood block separating cutter. 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.

Problems solved by technology

[0003] In order to solve the problems of air leakage and powder leakage in the existing wood block separation device, the present invention aims to provide a tubular wood block separation cutter, which is equipped with a collecting turning machine and a sieve cutting machine. The trigger separates the wood blocks mixed in the coal powder, and the sieve cutter cuts the wood blocks into granules and puts them into the coal powder bin together with the coal powder, which will not affect the normal production of the pulverizing system.
