Anti-blocking anti-tempering feeding device for biomass boiler

Abstract

The invention discloses an anti-blocking anti-tempering feeding device for a biomass boiler. The device comprises a conveying box, a conveying cavity is arranged in the conveying box, a charging box is fixedly connected to the right side end face of the conveying cavity, a charging cavity provided with a downward opening and communicating with the conveying cavity is arranged in the charging box,a vibration conveying device is arranged in the conveying cavity and used for conveying biomass fuel, a movement switch device is arranged on the upper side end face of the conveying cavity, a compression device for compressing biomass fuel is arranged in the charging cavity, the movement switch device provides power for the compression device to compress biomass fuel, the movement switch device and the compression device do synergic movement so as to detect the height of biomass fuel in the charging cavity, and compression and fuel charging are automatically carried out after the height of the biomass fuel reaches a set value. The blocking probability can be reduced, and ignition and tempering phenomena of fuel in the charging mechanism are avoided

Description

technical field [0001] The invention relates to the technical field of burner fuel supply, in particular to a material feeding device used for preventing material jamming and tempering of a biomass boiler. Background technique [0002] Biomass fuel: refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice bran, etc.), the application of material fuel is actually mainly biomass briquette fuel, which is the use of agricultural and forestry waste As a raw material, through crushing, mixing, drying, extrusion and other processes, it is made into various shaped fuels. The current biomass boiler fuel feeding device is prone to material jamming, and because the feeding device is always connected to the burner, the burner The combustion inside is easy to spread into the feeding device to form backfire, and the present invention explains a kind of equipment that can solve the above-mentioned problems. ...

[0002] Biomass fuel: refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry wastes (such as straw, sawdust, bagasse, rice bran, etc.), the application of material fuels, in fact, mainly biomass briquettes, is the use of agricultural and forestry wastes As a raw material, through crushing, mixing, drying, extrusion and other processes, various shaped fuels are made. The current biomass boiler fuel feeding device is prone to material jamming, and because the feeding device is always connected with the burner, the burner The combustion inside is easy to spread into the feeding device to form a flashback. A kind of equipment that can solve the above-mentioned problems is explained in the present invention.
