Description

Mixing equipment for biomass fuel processing

technical field

The utility model belongs to the technical field related to fuel processing, in particular to a stirring device for biomass fuel processing.

Background technique

Biomass fuel refers to combustion as fuel, generally such as sawdust, bagasse, rice bran, etc. In national policies and standards, direct combustion of biomass is a highly polluting fuel. Biomass fuel uses agricultural and forestry waste as raw materials. Crushing, extrusion, drying and other processes, made into a variety of shapes such as block, granular, a new type of cleaning can be directly. Biomass pellet fuel mixer is a commonly used production equipment in the process of biomass fuel production. At present, most of the mixing shafts of mixing equipment on the market are located on the axis of the cylinder, so when the mixing equipment is working, the raw materials to be stirred near the inner wall of the cylinder cannot be fully stirred, resulting in incomplete mixing. Patent No. CN201721578417.1 A stirring equipment for the production of biomass pellet fuel with sufficient stirring. By setting discs, connecting rods, sliders, curved rods, movable plates and movable rods, the motor is driven by the rotating shaft, discs and connecting rods. The movable plate rotates around the rotating shaft, and the slider moves along the chute at the same time. The slider controls the direction of the movable plate through the crank rod. The two adjacent movable plates enhance the structural strength of the movable plates. The movable plates drive the raw materials to be stirred near the inner wall of the cylinder to move, so that the raw materials near the inner wall of the cylinder and the axis are mixed with each other to achieve a thorough mixing effect. , which solves the problem that most of the raw materials to be stirred near the inner wall of the cylinder cannot be fully stirred when the mixing equipment on the market is working. By setting the rotating shaft and the socket, the rotating shaft is in the shape of a triangular prism, and the shape and size of the socket are compatible with the rotating shaft. The motor drives the stirring shaft to rotate through the rotating shaft to stir the raw materials. During the stirring process, the granular raw materials to be stirred are easily Sticking to the surface of the stirring shaft will increase the weight and diameter of the stirring shaft and affect the normal operation of the stirring equipment. The stirring shaft can move in the vertical direction, and the stirring shaft can be shaken up and down regularly or knocked on the stirring shaft to achieve the effect of conveniently removing the surface-bonded granular materials . However, after the stirring of the device is completed, it is difficult to discharge the fuel substance, and there is a situation that the discharge is not complete. The fuel stirring is realized by the rotation of the stirring shaft, and the stirring efficiency is low.

In view of this, the utility model is proposed.
