Eccentric type biomass fuel feeder

Abstract

The invention provides an eccentric type biomass fuel feeder which is wide in fuel adaptability and low in failure rate. The eccentric type biomass fuel feeder comprises a shell. The shell comprises a semicircular arc plate and two end plates. An upper square flange is arranged above the shell, and a lower square flange is arranged below the shell. A shifting shaft is arranged in the shell. Centers of the shifting shaft and the semicircular arc plate coincide. Two ends of the shifting shaft are fixed on the end plates through round flanges respectively. Bearings are arranged between the shifting shaft and the round flanges. One end of the shifting shaft is connected with a speed-reducing motor driving mechanism. A plurality of shifting pieces on the same circumference are distributed on the shifting shaft evenly. The center line of the upper square flange is arranged perpendicularly, an included angle is formed between the center line of the lower square flange and the center line of the upper square flange, the center line of the shifting shaft is perpendicular to the center line of the upper square flange, and a horizontal distance, namely an eccentric distance, is reserved between the center of the shifting shaft and the center of the upper square flange.

Description

technical field [0001] The present invention relates to a feeder, especially an offset biomass fuel feeder. Background technique [0002] Biomass briquetting fuel is made of agricultural and forestry wastes such as straw, sawdust, bagasse, rice bran, peanut shells, etc. Cylindrical, granular, a new type of clean fuel that can be directly burned. Biomass briquette fuel is an important part of sustainable energy. [0003] The combustion equipment of biomass briquetting fuel is a boiler. In order to reduce the labor intensity of the stoker, boilers with an evaporation rate greater than 4 tons / hour usually use mechanical equipment to inject fuel. At the same time, due to the particularity of boiler combustion, a balanced ventilation boiler must ensure that the furnace body is sealed to prevent a large amount of cold air from leaking into the furnace and causing unstable combustion. Therefore, how to choose the feeding equipment of biomass briquette fuel has become the primar...

Problems solved by technology

However, its disadvantage is that it can only be used to transport powdery and small granular materials. For bulky or large-sized biomass fuels, material jams and shells will occur frequently, seriously affecting the normal operation of the boiler.

[0007] The star feeder is also an option, but it is the same as the screw feeder. Although it can achieve a good seal at the feeding end, it is also limited to powder and small granular materials. For lumps or specifications Larger biomass fuels also have the phenomenon of material jams and shells, and the fuel adaptability is not wide

[0008] There is also the method of directly arranging the hopper on the grate and feeding directly by pushing the grate, but its defect is that the hopper is close to the grate, and the hopper is often burned out due to the fuel backburning, so it is not suitable for use.
