Dedusting device for biomass fuel

Abstract

The invention discloses a dedusting device for biomass fuel. The dedusting device comprises a bottom plate, a motor, a dust stopping cylinder, a roller and a dust collection fan, the dust stopping cylinder is arranged on the bottom plate, the outer wall of the roller is in a sifting net shape, the roller transversely penetrates through the interior of the dust stopping cylinder, the two ends of the roller are located outside the dust stopping cylinder respectively, and a feeding port and a discharging port are formed in the two ends of the roller respectively; support roller assemblies for supporting a device body to be arranged on the bottom plate are arranged below the two ends of the roller, a gear ring is arranged on the outer wall of one end of the roller, the motor is arranged on thebottom plate, a gear meshed with the gear ring on the outer wall of the roller is coaxially connected to a main shaft of the motor, spiral guiding sheets are arranged on the inner wall of the roller,the spiral guiding direction of the spiral guiding sheets is the direction of the discharging port of the roller, and the dust collection fan is communicated with the interior of the dust stopping cylinder. The dedusting device is simple and novel in structure, low in cost, convenient to use and high in dedusting efficiency.

Description

Technical field [0001] The invention relates to the technical field of biomass fuel processing, in particular to a biomass fuel dust removal device. Background technique [0002] Exhaust gas is generated during the production of biomass briquette, and the exhaust gas contains a large amount of dust. If it is directly discharged into the atmosphere, it will cause serious pollution to the environment. Therefore, it is extremely necessary to remove the dust from the exhaust gas. At present, the dust removal device used for biomass fuel is mainly composed of hot air pipe, cyclone dust collector, induced draft fan and precipitation chamber. The drying drum is connected to the hot air pipe, the hot air pipe is connected to the cyclone dust collector, and the outlet pipe of the cyclone dust collector is connected to the induced draft fan. , The induced draft fan is connected to the third intake pipe. The dust removal mechanism is that the cyclone dust collector rotates the dust-laden a...

AI Technical Summary

Problems solved by technology

Since the components of the dust removal device are all rigidly connected, the strong vibration generated by the rotation of the induced draft fan motor will cause the dust removal device to vibrate. After a period of time, the ports at the connection points of each component will become loose, which will cause air leakage. The dust removal efficiency of the rotary dust removal device is greatly reduced, and the loose connection between components will reduce the service life of the dust removal device and cause safety hazards
