AI Technical Summary

Technical Problem

The anti-fired device of the biomass boiler is prone to transmission of fire to the top due to fuel blockage, causing combustion in the hopper, affecting the safe operation and economic benefits of the boiler.

Method used

A biomass boiler pellet fuel anti-fire structure is designed, including a hopper, a drive device and an anti-fire assembly. The anti-fired component consists of a circular plate, a rotating roller, an extrusion chamber, a storage tank and a hoist plate. Through the cooperation of the extrusion block and a spring, the hoist plate can push out the fuel stuck in the storage tank to avoid blockage and fire transmission.

Benefits of technology

It effectively prevents fuel clogging and fire transmission to the top, ensures the safe operation and economic benefits of the boiler, and also has the function of quantitative addition.

Abstract

The utility model discloses a biomass boiler granular fuel anti-reverse-burning structure, which relates to the technical field of boiler hopper equipment, and comprises a hopper, a driving device is mounted on the side wall of the hopper, the output end of the driving device is fixedly connected with an anti-reverse-burning assembly positioned in the hopper, the anti-reverse-burning assembly comprises a circular plate and a rotating roller, and the rotating roller is fixedly connected with the circular plate. The circular plates are fixedly connected to the two ends of the rotating roller, an extrusion cavity is formed in the rotating roller, storage grooves are formed in the rotating roller in a circumferential array mode, and jacking plates are slidably connected into the storage grooves. According to the particle fuel anti-reverse-burning structure of the biomass boiler, fuel clamped in the storage groove can be pushed out, the situation that the blocked fuel passes through a circle of rotation and transmits kindling to the fuel on the top is avoided, the anti-reverse-burning effect is achieved, safe operation and economic benefits of the boiler are guaranteed, and meanwhile the structure is suitable for popularization and application. The multiple storage grooves have the quantitative adding effect.
