Twin auger feeder

Abstract

The invention provides a conveyer with double augers, and belongs to the technical field of heating equipment. The conveyer with the double augers comprises a combustion chamber and an ignition system, wherein a conveying mechanism is arranged on one side of the combustion chamber and specifically comprises a conveying pipe, a connecting pipe, a feeding pipe, a feeding opening and a spiral pushing rod; the conveying pipe is arranged on one side of the combustion chamber; the connecting pipe is arranged at the tail of the conveying pipe; the feeding pipe is arranged on the connecting pipe; the feeding opening is formed in an end of the feeding pipe; the spiral pushing rod is arranged in the conveying pipe and the feeding pipe; a tempering-proof plate is arranged in the connecting pipe; and a slag pushing mechanism is arranged on one side of the combustion chamber and is positioned below the conveying mechanism. Materials are conveyed by the conveying pipe and the feeding pipe which are arranged vertically; the tempering-proof plate is arranged between the conveying pipe and the feeding pipe, so that a tempering phenomenon is avoided, and the safety is improved; and slag in the combustion chamber can be removed by the slag pushing mechanism regularly, the slag can be automatically removed, the problem that cokes are generated easily during combustion and are adhered to the bottom of the combustion chamber is solved, the normal combustion space and smooth ventilation of the combustion chamber are guaranteed, and the combustion efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of heating equipment, and relates to equipment for burning biomass raw materials to provide heat, in particular to a double auger feeder. Background technique [0002] Biomass fuel heating equipment uses all waste crops such as straw, rice straw, fuelwood, wood chips, peanut shells, melon seed shells, beet pulp, bark, etc., and is finally made into granules by crushing, mixing, extrusion, drying and other processes. Fuel, the fuel burns for a long time, the temperature of the enhanced combustion furnace is high, and it is economical. At the same time, it has no pollution to the environment, zero emission of CO and zero emission of SO. It is a renewable energy source, recyclable, and can replace wood, coal, and natural gas. Correspondingly, the development of biomass fuel heating equipment is promoted. All kinds of heating equipment are designed with corresponding feeders, because the feeder is directly conne...

Problems solved by technology

[0002] Biomass fuel heating equipment uses all waste crops such as straw, rice straw, fuelwood, wood chips, peanut shells, melon seed shells, beet pulp, bark, etc., and is finally made into granules by crushing, mixing, extrusion, drying and other processes. Fuel, the fuel burns for a long time, the temperature of the enhanced combustion furnace is high, and it is economical. At the same time, it has no pollution to the environment, zero emission of CO and zero emission of SO. It is a renewable energy source, recyclable, and can replace wood, coal, and natural gas. Correspondingly, the development of biomass fuel heating equipment is promoted. All kinds of heating equipment are designed with corresponding feeders, because the feeder is directly connected with the combustion chamber. Due to the increase of the temperature and pressure in the combustion chamber during the combustion process, there will be Backfire phenomenon, the fuel in the feeder is ignited, and the fuel in the storage bin is ignited, and the equipment will be burned at the slightest, and a fire accident will occur at the worst. Therefore, the defects of the existing feeder have potential safety hazards. In addition, the combustion chamber The final biomass fuel will coke and adhere to the bottom of the combustion chamber. If it is not treated for a long time, it will affect the combustion effect and reduce the combustion rate, and manual treatment is relatively troublesome.
