Energy-saving granulating and forming equipment for manufacturing biomass fuel

Abstract

The invention discloses energy-saving type granulation forming equipment for biomass fuel manufacturing, and relates to the technical field of granulation forming, the granulation forming equipment comprises a rack, a transmission box is arranged below the rack, a power motor and a granulation box are installed on the transmission box, a feeding mechanism is installed on the rack, and a feeding mechanism is installed on the rack; the feeding mechanism is connected with the granulation box through a connecting pipe, the feeding mechanism mixes raw materials, high-temperature steam is introduced into the feeding mechanism, the raw materials are heated and humidified through the high-temperature steam, so that the raw materials reach the temperature and humidity required by granulation, the raw materials are rubbed into uniform pellets through the granulation box firstly, and then the raw materials are fed into the granulation box through the connecting pipe. The raw materials are kneaded into the pellets, so that the connection strength between the raw materials is enhanced, the condition that the raw materials are broken after being granulated is avoided, and the granulation effect is improved.

Description

technical field [0001] The invention relates to the technical field of pelletizing and molding, in particular to an energy-saving biomass fuel manufacturing pelletizing and molding equipment. Background technique [0002] Biomass fuel refers to the burning of biomass materials as fuel, which is mainly different from fossil fuels. In the current national policies and environmental protection standards, the direct combustion of biomass is a highly polluting fuel, which is not allowed to be used in cities. The application of biomass fuel is actually mainly biomass molding fuel. A new type of clean fuel that can be directly burned in various shapes (such as blocks, granules, etc.) by mixing, extrusion, drying and other processes. [0003] The existing technological process needs to consume a lot of energy. In the process of granule pressing and forming, a driving mechanism is required to drive the forming roller in the ring film granulator to rotate, so that the forming roller ...

AI Technical Summary

Problems solved by technology

[0003]The existing technological process needs to consume a lot of energy. In the process of pellet pressing and molding, a driving mechanism is required to drive the forming roller in the ring film granulator to rotate, so that the forming roller Extruding the raw material requires an additional motor to drive the cutter to cut the raw material outside the ring film. The entire forming process requires the cooperation of multiple motors, resulting in increased energy consumption of the overall equipment; in addition, the mechanical wear during the forming process is relatively large , therefore, the product manufacturing cost of the existing granule molding machine is relatively high

[0004]The existing molding process is direct extrusion molding, resulting in a low degree of connection between raw materials, and the biomass particles after granulation are easy to re-disperse , fragmentation, resulting in low production efficiency of biomass fuel pellets
