Description

A new type of biomass granulation device with automatic feeding control

technical field

The invention relates to a biomass particle granulator, in particular to a novel biomass particle granulator that can automatically control feeding. The invention belongs to the technical field of mechanical manufacturing.

Background technique

The working principle of the biomass granulator is that the conditioned crushed material enters the granulation device from the feed auger, and is evenly fed into the pressing space in the mold by means of gravity and the action of the feeding scraper. Under the strong extrusion of the rollers of the granulator, the material is gradually compacted, squeezed into the die hole of the mold and formed in the die hole. Since the extrusion of the material between the die rollers is continuous, after forming The material is continuously discharged from the die hole in a columnar shape, and then cut into pellets of the required length by a cutter, but the productivity of the pellets is affected by the feed amount of raw materials during the production process. The feed amount of the current biomass pellet production It cannot be changed in real time, resulting in unstable particle production rate and low production efficiency.

The technical solution of the present invention is: a new type of biomass particle granulation device that can automatically control feeding, including a frame, a power device, a feeding device, a granulation device, and a weighing device, and is characterized in that the power device on the frame , connected to the granulation device through the reducer, the granulation device is connected to the feeding device through the feeding auger of the feeding device, and the right side of the granulation device enters the particle recovery bin and the weighing device of the load cell through the discharge hopper. Including the installation of a granulator, the pellet raw material box controls the speed of the feeding auger to provide raw materials to the granulator through the feeding motor, and the motor drives the granulator to work through the reducer, and the biomass particles produced by the granulator pass through the discharge barrel After entering the particle recovery bin, the load cell detects the change in the increase of the particle mass per unit time. When it is detected that the increase in mass becomes smaller, the feeding motor increases the speed, and the feeding auger increases the feeding amount of raw materials to keep the production rate of the pellets stable. When the increase in mass detected becomes larger, the feeding motor reduces the speed Long reduce the feeding amount of the principle, prevent the pellet mill from overloading, reduce the wear of the mold, and increase the life of the equipment.

The beneficial effects of the present invention are:

The invention is a novel biomass granulation device capable of automatically controlling feeding, which changes the rotational speed of a feeding motor by detecting the increase in particle mass per unit time through a weighing sensor. Use the feeding motor to pass the speed of the feeding auger to control the feeding amount of pellet raw materials. When the increase in pellet mass decreases, increasing the feed amount can keep the productivity of biomass pellets stable. When the increase in pellet mass is too large Reducing the feeding amount can protect the mold of the granulator and increase the life of the granulator.

The invention has simple structure, ingenious design and low cost, improves the production efficiency of biomass granules, reduces the labor intensity of workers, improves the working environment quality of workers, and realizes continuous automatic production.
