Self-cleaning material splitting box of wood flour fuel boiler

Abstract

The invention discloses a self-cleaning material splitting box of a wood flour fuel boiler. The self-cleaning material splitting box comprises a box body, the left side wall of which communicates to adust collecting header pipe; a screen, the front surface of which inclines to the dust collecting header pipe, is arranged in the box body; the lower end of the screen is connected to a partition plate; a gap is reserved between the partition plate and the inner wall of the box body below the dust collecting header pipe as a wood chip channel; the wood chip channel communicates to a return port in the top of the box body successively through a pipeline provided with a flour mill and a lifter; a discharge hopper is arranged in the bottom of the box body below the screen; a blowing pipe communicating to an air outlet of an air blower is arranged on the right side wall of the box body; the orifice of the blowing pipe faces the back surface of the screen; the orifice of the blowing pipe is also hermetically connected to an iron cover plate; the upper portion of the cover plate is rotatably connected to the upper edge of the orifice of the blowing pipe through a hinge; and a magnet for adsorbing the lower portion of the cover plate is fixedly mounted at the lower edge of the orifice of the blowing pipe. The self-cleaning material splitting box disclosed by the invention is cleaned automatically intermittently without inputting the cleaning labor force, so that the labor intensity is reduced effectively, and continuous operation of equipment is also not affected.

Description

technical field [0001] The invention relates to the field of wood equipment, in particular to a self-cleaning distribution box for a wood powder fuel boiler. Background technique [0002] The wood industry will produce a large amount of wood chips and wood powder during the processing process, polluting the environment in the factory building, and there is a certain hazard to the health of the workers. The traditional treatment method is to absorb wood powder through a vacuum device. For larger diameter The wood chips are collected separately and crushed to become wood powder, which is used as fuel for boilers, which not only protects the environment but also saves costs, and is environmentally friendly and energy-saving; however, it is necessary to classify the wood chips and wood powder, which requires more manpower. The higher the trend, it is not conducive to reducing the manufacturing cost of the plate. [0003] At present, there is a heating device for a plate dryer, ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a self-cleaning distribution box for wood powder fuel boilers, which can solve the problem that the current distribution box cannot see whether there are wood chips stranded and accumulated, and manual inspection and cleaning are performed by regular shutdown, resulting in high labor intensity. And the problem that the equipment cannot run continuously
