Feeding apparatus of biomass silo

Abstract

The invention discloses a feeding device used in biomass storage hopper, comprising a storage hopper, a switching device and a transporting device; the switching device is arranged at the lower part of the storage hopper; the transporting device is arranged at the bottom of the storage hopper; the switching device comprises a plurality of switchers and enwinding breakers which are laid in parallel; the switchers are provided with a switching shaft; a plurality of bar sets are arranged on the switching shaft along the axial direction with equal distance; 1 to 6 switching bar pairs are arranged in each bar set along axial direction of the switching shaft; the enwinding breakers are provided with a fixed shaft; doctor bars matched with the switching bars are arranged on the fixed shaft. The feeding device used in the biomass storage hopper of the invention can break bridging or scaffolding of the biomass material in the storage hoppers, can also break the enwinding of biomass stalks on the switching shaft during the rotation of the switcher, thus realizing continuous, stable and adjustable material discharging of the biomass material piled in the storage hopper, and forming strong direction on soft stalks. The feeding device realizes the separation of switching and transporting and becomes more flexible on feeding control.

Description

technical field [0001] The invention relates to a feeding device, in particular to a feeding device for a biomass silo. Background technique [0002] Nowadays, the country is vigorously developing new energy sources, among which biomass energy is a particularly important direction for my country, a large agricultural country, due to its cleanliness and renewability. In the industrial utilization of biomass energy, whether it is combustion or gasification, continuous and stable feeding is very important, because it is related to the stable operation of the entire system. [0003] The accumulation and compaction of biomass materials in the silo leads to poor fluidity. Therefore, in the conventional feeding device, there will be shed materials and bridges when feeding materials, which will affect the continuous transportation of materials. Especially for biomass straw, the winding characteristics are strong, and they are interlaced with each other. When they are piled up and c...

Problems solved by technology

[0003] The accumulation and compaction of biomass materials in the silo leads to poor fluidity. Therefore, in the conventional feeding device, there will be shed materials and bridges when feeding materials, which will affect the continuous conveying of materials.

Especially for biomass straw, the winding characteristics are strong, and they are interlaced with each other. When they are piled up and compacted in the silo, shed materials and bridges often occur, which seriously affect the continuous transportation of materials.

Since the material cannot be transported continuously and stably, the system operation is unstable, which is very unfavorable for the utilization of biomass energy. Therefore, it is urgent to solve the problem of continuous and stable transport of biomass materials.
