Problems solved by technology
[0002] At present, the feed inlets of the known biomass pellet boilers have inclined feed inlets and straight feed inlets. Biomass particles are sent to the center of the burner, which is not conducive to the combustion of biomass particles
The straight feed port can send the biomass particles directly to the middle of the burner, which is beneficial to the combustion of the biomass particles, but it is prone to tempering when feeding

Embodiment Construction
[0019] Such as figure 1 , 2 , 3, 4, 5, 6, and 7, an anti-backfire rotary valve used in the feed system of a biomass boiler includes a valve body 6, a front end cover 2, a rear end cover 3, and a rotating shaft 1. 6 is provided with a front end cover 2 at the front end, a rear end cover 3 is provided at the rear end of the valve body 6, a rotating shaft 1 is arranged in the middle of the valve body 6, a blade 5 is provided on the rotating shaft 1, and a gear is installed at the front end of the rotating shaft 1. The valve body 6 is cast by a mold. The upper and lower surfaces of the valve body 6 are square planes. The four legs of the square plane are provided with screw holes 10, and the center is provided with a circular hole. The upper and lower circular holes are vertically opposed to allow fuel to enter the burner. A hollow cylinder is provided in the middle of the valve body 6, and the front and rear ends of the hollow cylinder are respectively connected with the front cove...

Disclosed is an anti-backfire rotary valve used in a biomass boiler feeding system. The anti-backfire rotary valve comprises a valve body, a front end cap, a rear end cap and a rotating shaft, the front end cap is arranged at the front end of the valve body, the rear end cap is arranged at the rear end of the valve body, the rotating shaft is arranged in the middle of the valve body, four blades are arranged on the rotating shaft, and a gear is mounted at the front end of the rotating shaft. The front end of the rotating shaft penetrates a ball runner hole and a rotating shaft hole in the front end cap, the rear end of the rotating shaft penetrates a ball runner hole and a rotating shaft hole in the rear end cap, and the four blades are welded on the rotating shaft between the front end cap and the rear end cap. The anti-backfire rotary valve has the advantages of firmness, durability, simple structure, convenience in mounting and maintenance and capabilities of directly feeding biomass particles to the middle of a burner and preventing backfire.
Description
Technical Field: [0001] The invention relates to a feed valve for a biomass pellet boiler, in particular to an anti-backfire rotary valve used in a biomass boiler feed system. Background technique: [0002] At present, the feed port of the known biomass pellet boiler has an inclined feed port and a straight feed port. When the inclined feed port feeds, the burner is not easy to produce backfire and smoke back phenomenon, but it cannot be The biomass particles are sent to the center of the burner, which is not conducive to the combustion of biomass particles. The straight feed inlet can send biomass particles directly to the middle of the burner when feeding, which is beneficial to the combustion of biomass particles, but it is easy to backfire during feeding. Summary of the invention: [0003] The purpose of the present invention is to provide an anti-backfire rotary valve used in a biomass boiler feed system that can directly send biomass particles to the middle of the burner wi...
