Mixing cage structure of firebrand particle furnace

Abstract

The invention provides a cage stirring structure for a wood-burning pellet stove, which includes a hopper, a conveyor belt located directly below the outlet of the hopper, and a control system for controlling the switch of the hopper and the movement of the conveyor belt; the conveyor belt includes sequentially connected first One transmission area, the second transmission area and the third transmission area, the first transmission area is set horizontally, its entrance is located directly below the outlet of the feeding hopper, the second transmission area and the first transmission area form an angle of 135-160° Setting, the third transmission area and the second transmission area are set at an angle of 90-120°, and the second transmission area and the third transmission area form an inverted "V" shape. The cage stirring mechanism provided by the invention can make the wood-burning particles form multiple air barriers during the automatic feeding process, effectively preventing the flame in the combustion chamber from being reversely transmitted to the hopper along the wood-burning particles on the conveyor belt and igniting the hopper Wood pellets inside for increased safety in wood pellet stoves.

Description

technical field [0001] The invention relates to the field of biomass furnaces, in particular to a cage stirring structure for wood-burning pellet furnaces. Background technique [0002] Biomass stove refers to the indoor heating equipment that is independent or built on the wall, uses combustibles as energy, and has a chimney inside. According to the different burning materials, it can be divided into the following four types: 1) coal-burning type; 2) wood-burning type; 3) wood-burning pellet type; 4) alcohol-burning type. [0003] The wood-burning pellet stove mainly uses the combustion of wood, straw, corn stalks, garbage and other particles to generate heat and achieve heating effects. It is suitable for families in areas without gas supply. [0004] Because wood-burning pellet stoves use wood-burning pellets as fuel, they need to be transported from the hopper to the combustion chamber through a conveyor belt. At the same time, in the field of intelligent wood-burning p...

Problems solved by technology

[0004] Because wood-burning pellet stoves use wood-burning pellets as fuel, they need to be transported from the hopper to the combustion chamber through a conveyor belt. At the same time, in the field of intelligent wood-burning pellet stoves, automatic feeding is usually used to continuously provide fuel for the combustion chamber. In this way, when the temperature of the raw materials burned in the combustion chamber is too high or there are abnormal conditions such as sparks splashing, the combustion flame may be reversely transmitted to the hopper along the conveyor belt, further igniting the wood pellets inside the hopper, causing a major safety accident
