Description

Technical Field

[0001] The utility model relates to the technical field of biomass fuel, in particular to a drying device for producing biomass particles. Background Art

[0002] Biomass pellet fuel is actually the direct combustion of biomass energy, which is the processing and utilization of biomass. Direct combustion methods can be divided into four types: stove combustion, boiler combustion, garbage combustion and solid fuel combustion. Among them, solid fuel combustion is a newly promoted technology, which solidifies biomass into a shape and then uses traditional coal-fired equipment to burn it. The advantage is that it makes full use of biomass energy to replace coal, reduces CO2 and SO2 emissions, is beneficial to environmental protection and controls greenhouse gas emissions, slows down climate change, and reduces the occurrence of natural disasters. The drying device for biomass particle production described in Publication No. CN220250533U has a cover plate installed on the top of the body, and a blower installed on one side of the body, an air inlet pipe connected to one side of the blower, and a heating machine connected to one end of the air inlet pipe, an air outlet pipe connected to one side of the heating machine, and an exhaust fan connected to one end of the air outlet pipe, a bottom plate connected to the bottom of the heating machine, a permanent magnet synchronous motor installed at the bottom of the body, and a gear connected to the bottom of the permanent magnet synchronous motor, through the cooperation of various components, the drying process of biomass particles is realized, but the prior art still has the following defects:

[0003] 1. The prior art starts the permanent magnet synchronous motor to drive the gear at the bottom to rotate, thereby driving the stirring shaft and the connecting shaft to rotate together. The stirring blades on the outside of the connecting shaft can stir the biomass particles to facilitate drying. However, if the stirring blades are used alone, the turning speed of the biomass particles is slow, resulting in more time required for the drying operation and reduced processing efficiency.

A grid plate is installed on the outside of the drying box for holding the particles to be dried. However, the drying box needs to be taken out manually after drying, which is time-consuming and laborious. In addition, during the stirring process, there is a risk that the particles will fall to the bottom of the machine body. Utility Model Content
