Problems solved by technology

In the existing biomass fuel production enterprises, different types of biomass fuels are basically extruded and granulated through extrusion dies of different specifications, so different biomass fuels basically require extrusion dies of different specifications. Increase the production cost of biomass fuel, and the density of biomass fuel produced by ordinary extrusion machinery is relatively high, thus affecting the combustion effect of biomass fuel particles

Embodiment 1

[0024] Such as Figure 1 to Figure 2 As shown, a kind of extrusion die for biomass fuel comprises a positioning head 1, and several through holes 1a are arranged on the positioning head 1, and a granulation unit 2 is installed in a detachable manner in the through holes 1a, and the positioning head 1 Also be installed with rotating shaft 3 on the rotating shaft 3, segment cutter 4 is installed on the rotating shaft 3, rotating shaft 3 is connected with positioning shaft. When in use, the rotating shaft 3 is connected with an external power source, and the external power source drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the segmented knife 4 to rotate, cutting off the long strip of biomass fuel to form particles, replacing the traditional through The method of self-weight forming, and the granulation unit 2 of different specifications can be replaced according to different types of biomass fuels, which improves the use range of the device, is conveni...

Embodiment 2

[0033] Such as image 3 As shown, the difference from Embodiment 1 is that the gas filling head 23 is arranged in the material introduction cavity 25a, which can accelerate the flow velocity of the biomass fuel to form an uneven The air bubbles increase the combustion efficiency of biomass fuel.

Embodiment 3

[0035] Such as Figure 4 As shown, the difference from Embodiment 1 is that the gas filling head 23 is a hemispherical gas filling head, which can make the biomass fuel form smaller holes during the extrusion process, thereby reducing the The amount of deformation ensures the structural strength of the biomass fuel.

[0036] When in use, the biomass fuel enters the molding channel on the mold cavity 21 through extrusion, and the biomass fuel passes through the conduit 22 to form a hollow structure, and in the process, the external gas source works to send the gas into the conduit 22, and the gas passes through The gas filling head 23 on the conduit 22 physically fills the biomass fuel in the mold cavity 21, so that holes are formed in the hollow structure of the biomass fuel, and the natural foaming of the biomass fuel is realized. At the same time, the external power source works, and the power source Drive the rotating shaft 3 to rotate, and the rotating shaft 3 drives the ...

Abstract

The invention discloses an extrusion die for biomass fuel. The extrusion die comprises a positioning head, wherein a plurality of through holes are formed in the positioning head; granulation units are arranged in the through holes in a detachable manner; a rotating shaft is arranged on the positioning head; a segmenting knife is arranged on the rotating shaft; and the rotating shaft is connectedwith a positioning shaft. According to the extrusion die disclosed by the invention, the granulation units are arranged in the detachable manner, so that granulation of different types of biomass fuelis realized, the application range of the device is widened, the maintenance is convenient, and the manpower and material resources are saved. Moreover, the produced biomass fuel has a hollow structure, and is large in contact area with oxygen and high in combustion efficiency.

Description

technical field [0001] The invention relates to the technical field of production equipment for biomass fuel, in particular to an extrusion die for biomass fuel. Background technique [0002] With the development of the times, more and more biomass fuels are used, and the biomass fuel manufacturing industry has achieved unprecedented development. Biomass fuel refers to a new type of clean fuel that uses biomass materials as raw materials and makes them into various shapes through crushing, mixing, extrusion, drying and other processes, which can be directly burned. In the existing biomass fuel production enterprises, different types of biomass fuels are basically extruded and granulated through extrusion dies of different specifications, so different biomass fuels basically require extrusion dies of different specifications. The production cost of biomass fuel is increased, and the density of biomass fuel produced by ordinary extrusion machinery is relatively high, thus aff...
