Problems solved by technology
[0002] With the reduction of fossil energy reserves such as coal, oil, and natural gas, the development of renewable energy has become a global hot issue. Biomass energy has the characteristics of being renewable, widely distributed, low pollution, and very rich in resources. High is easy to catch fire. Existing boilers are prone to backfire when burning biomass fuel, resulting in fuel combustion during the feeding process. In severe cases, the hopper and the entire feeding system will be burned, making the boiler unable to feed normally, seriously affecting the safe operation of the boiler , In addition, the existing feeding device of the biomass burning boiler still has the problems of large volume, inconvenient installation, poor adjustability of feeding speed and easy material blockage

The invention discloses a tempering preventing feeding device of a biomass burning boiler. The tempering preventing feeding device comprises a shell, a gear motor is arranged on the lower right portion in the shell, the power output end of the gear motor is connected with a driving chain wheel, a turning chain wheel is arranged above the driving chain wheel, and a roller device and a rotary chain wheel are arranged on the left side and the right side of the turning chain wheel respectively. The tempering preventing feeding device has the advantages that a first tempering preventing band and a third tempering preventing band are effectively separated, it is ensured that tempering cannot occur, and the boiler operates safely; feeding speed is regulated by changing the width of a feeding channel, the wider the feeding channel is, the higher the feeding speed is, the feeding speed can be regulated by changing the gear ratio of the chain wheels, the feeding speed can be regulated by changing the speed ratio of the gear motor, and the adjustability of the feeding speed is good; a rotary feeding sheet is arranged in a feeding chamber to achieve rotary feeding, a material layer is pushed constantly, it is ensured that blocking cannot occur, and the tempering preventing feeding device is compact in structure, small in size, convenient to mount and safe to use.
