Description

Technical Field

[0001] The present invention relates to the technical field of biomass boiler feeding equipment, and particularly to a biomass boiler material controller. Background Art

[0002] With the reduction of reserves of fossil fuels such as coal, oil, and natural gas, the development of renewable energy has become a global hot issue of concern. Biomass energy has the characteristics of being renewable, low-pollution, widely distributed, and abundant in total amount, and can partially replace fossil energy for human use. The development and utilization of biomass energy have attracted more and more attention. At present, the material controller set at the feeding port of the biomass boiler controls the feeding amount of the biomass formed fuel. Since the material feeding device on the surface of the drum of the existing material controller is tooth-shaped, during the long-term feeding process, a large amount of biomass formed fuel enters from the feeding port and presses on the material controller. During the operation of the material controller, the situation of material jamming is likely to occur between the material controller and the wall surface of the vertical feeding port, resulting in inaccurate material control. Summary of the Invention

[0003] The purpose of the present invention is to propose a biomass boiler material controller for the problem of material jamming during the operation of the material controller in the prior art.

[0004] The technical solution adopted by the present invention to solve the above technical problems is as follows:

[0005] A biomass boiler material controller includes: a housing 1, the housing 1 is cylindrical, and a plurality of grooves 2 are arranged on the surface of the housing 1 along the axial direction. A material control tooth 3 matching with the groove 2 is arranged in the groove 2. A retaining edge 2-1 is arranged in the groove 2. A retaining tooth 3-1 is arranged on the material control tooth 3. The retaining edge 2-1 and the retaining tooth 3-1 limit the separation of the groove 2 and the material control tooth 3. A spring is arranged between the groove 2 and the material control tooth 3.

[0006] Further, the material control tooth 3 is composed of a plurality of auxiliary teeth 5. The retaining tooth 3-1 is arranged on the auxiliary tooth 5. The retaining tooth 3-1 and the retaining edge 2-1 limit the separation of the auxiliary tooth 5 and the groove 2. A spring is arranged between the auxiliary tooth 5 and the groove 2.

[0007] Further, a rotating groove 11 is processed on the auxiliary tooth 5. A feeding ball 8 is arranged in the rotating groove 11. The rotating groove 11 restricts the separation of the feeding ball 8 from the material control tooth 3. The depth of the rotating groove 11 is greater than the radius of the feeding ball 8 and less than the diameter of the feeding ball 8.

[0008] Further, the material controller further includes a material shifting roller 6. The material shifting roller 6 is a cylinder. A rotating groove 7 is provided on the material control tooth 3 along the axis direction of the housing 1. The material shifting roller 6 is arranged in the rotating groove 7. The rotating groove 7 restricts the separation of the material shifting roller 6 from the material control tooth 3. The depth of the rotating groove 7 is greater than the radius of the material shifting roller 6 and less than the diameter of the material shifting roller 6.

[0009] Further, the material controller further includes a plurality of material shifting balls 8. A rotating groove 11 is machined on the material control tooth 3. The material shifting balls 8 are arranged in the rotating groove 11. The rotating groove 11 restricts the separation of the material shifting balls 8 from the material control tooth 3. The depth of the rotating groove 11 is greater than the radius of the material shifting balls 8 and less than the diameter of the material shifting balls 8.

[0010] Further, the rotating grooves 11 are uniformly arranged on the material control teeth 3.

[0011] Further, an anti-slip layer is provided on the material control tooth 3.

[0012] Further, the anti-slip layer is anti-slip convex ridges 301 uniformly arranged on the surface of the material control tooth 3.

[0013] The beneficial effects of the present invention are as follows:

[0014] In this application, the telescopic movement of the material control tooth is controlled by the compression of the spring. When the biomass formed fuel presses against the vertical wall surface of the material control tooth and the feed inlet, through the rolling friction of the cylindrical roller and the telescopic movement of the material control tooth, the material can be controlled, and there will be no material jamming.

[0029] During specific implementation, the material controller can be driven to rotate by the drive belt 9 of the motor 10. The biomass formed fuel is placed at the feed inlet. The biomass formed fuel contacts the material control tooth 3, the wall surface of the material controller drum, and the vertical wall surface of the feed inlet. The rotation of the material controller and the gap between two material control teeth 3 drive the biomass formed fuel. When the fuel is pressed by the material control tooth 3 against the vertical wall surface of the feed inlet, the material control tooth 3 will be compressed into the groove 2. When the fuel drops, the material control tooth 3 will return to its original state under the elastic force of the spring 4. When one material control tooth 3 discharges the material, the adjacent material control tooth 3 will immediately press the fuel between the material control tooth 3 and the vertical wall surface of the feed inlet, so that the fuel will not fall, achieving precise material control.
