Biomass fuel pelletizing producing device

Abstract

The invention discloses a biomass fuel pelletizing producing device which comprises a feeding hopper, a fixed cover and a housing, wherein a cavity is arranged inside the housing; the feeding hopper is fixedly arranged on the middle position of the top of the housing; and the bottom end of the feeding hopper extends to the top end position inside the cavity. A first extruding base and a second extruding base which are parallel to each other are separately arranged inside the housing, the bottom end of the first extruding base is provided with a second opening in communication with a first opening in the second extruding base; when the first extruding base is used for pelletizing and producing, dropped straws can slide into the second extruding base from the second opening, and can completely drop into the second extruding base from the second opening in an ascending and returning process of an extruding head inside the first extruding base; the specification of the extruding head is greater than that of the second opening which is closed, so that the second extruding base can be utilized to extrude and pelletize the straws, and thus, reciprocating motion for continuous production is achieved, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of biomass fuel processing, in particular to a biomass fuel granulation production device. Background technique [0002] Biomass fuel refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste, such as straw, sawdust, bagasse, rice bran, etc. In the current national policy and environmental protection standards, direct combustion of biomass is a highly polluting fuel. The actual application of biomass fuel is mainly biomass briquette fuel, which uses agricultural and forestry wastes as raw materials and makes them into various shapes (such as blocks, granules, etc.) through crushing, mixing, extrusion, drying and other processes. A new type of clean fuel that is directly burned. The biomass fuel has a large calorific value. At the same time, the biomass fuel is clean and hygienic, and the feeding is convenient. It reduces the labor intensity of the workers and greatl...

Problems solved by technology

[0003] Application number CN208928100U discloses a biomass fuel extrusion granulator, which has a structure of straw crushing, screening and extrusion granulation. According to the record of the patent specification, the function of extrusion granulation can be realized. However, due to In order to realize the crushing, screening and extrusion granulation of biomass fuel, it still has a large floor area, and the screening is not careful enough, so it is easy for the crushed straw to reach a suitable particle size to slip into the recycling box by mistake and be recycled. The incompletely crushed straw cannot be automatically put into the device for re-crushing and processing, which requires manual operation, which greatly affects the use effect and processing efficiency of the device. During the granulation process, it cannot be continuously crushed and granulated, and can only be processed at one time. Quantitative straw, otherwise the continuous processing will easily cause the crushed straw to slide from the discharge port to the inside of the granulation box, and it will fall on the upper surface of the extrusion block moving to the lower end during the extrusion process, affecting Defects in the operation of the device
