Abstract

The invention provides a biomass fuel feeding device and a biomass fuel furnace, and belongs to the field of furnace tools. The biomass fuel feeding device comprises a hopper and a raking assembly, wherein the bottom of the hopper is provided with a discharging port, the side portion of the hopper is provided with a material guide inclined wall which is arranged at an included angle with the vertical direction and extends to the discharging port, the raking assembly comprises a rotating shaft arranged in the hopper and a plurality of shifting rods arranged at intervals along the axial direction of the rotating shaft, each shifting rod is arranged along the radial direction of the rotating shaft, the projection of every two adjacent shifting rods in the radial plane of the rotating shaft isarranged at an included angle, and the shifting rods are used for shifting the biomass fuel on the material guide inclined wall towards the discharging port. The biomass fuel furnace comprises the above biomass fuel feeding device. According to the biomass fuel feeding device and the biomass fuel furnace, only a small amount of biomass fuel is in contact with the small-size shifting rods, so thatthe situations that biomass fuel is crushed and biomass fuel sticks the shifting rods are avoided, the adjacent shifting rods are not inserted into the biomass fuel at the same time, and the biomassfuel is prevented from being crushed.

Description

technical field

[0001] The invention belongs to the technical field of stoves, and more specifically relates to a biomass fuel feeding device and a biomass fuel stove. Background technique

[0002] The existing biomass fuel furnace uses a screw feeding mechanism for feeding. When in use, the operator sends the biomass fuel into the hopper, and the biomass fuel falls into the screw feeding mechanism from the discharge port at the bottom of the hopper, and the screw feeding mechanism The screw rod rotates to gradually push the biomass fuel into the furnace. However, because the biomass fuel is granular, the granular biomass fuel will be crushed by the screw rod during the conveying process of the screw feeding mechanism, which is not conducive to subsequent combustion. In severe cases, the biomass fuel will also jam the screw rod , resulting in feed interruption. Contents of the invention

[0003] The purpose of the present invention is to provide a biomass fuel feeding de...
