Self-cleaning material splitting box of wood flour fuel boiler

Abstract

The invention discloses a self-cleaning material distribution box for a wood powder fuel boiler, which comprises a box body whose left side wall is connected to a dust collection main pipe, and a screen with a front obliquely facing the dust suction main pipe is arranged in the box body, and the screen screen is The lower end is connected with a partition, and there is a gap between the partition and the inner wall of the box below the dust collection main pipe as a wood chip passage, and the wood chip passage is connected to the return at the top of the box through a pipeline provided with a mill and a hoist in turn. Material outlet, the bottom of the box below the screen is provided with a hopper, the right side wall of the box is provided with a blowing pipe connected to the air outlet of the blower, the mouth of the blowing pipe faces the back of the screen, and the blowing pipe The mouth of the nozzle is also sealed and connected with an iron cover plate, the top of the cover plate is connected to the upper edge of the nozzle of the blowing pipe through hinge rotation, and the lower edge of the nozzle of the blowing pipe is fixedly equipped with a magnet for absorbing the lower part of the cover plate. Intermittent automatic cleaning does not require labor for cleaning, which effectively reduces labor intensity and does not affect the continuous operation of the equipment.

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
