Application control system of straw biomass granulator

Abstract

The invention discloses an application control system of a straw biomass granulator. The control system comprises a heating control mechanism, a granulator control mechanism, a feeding machine controlmechanism and a total starting push button, wherein the heating control mechanism, the granulator control mechanism and the feeding machine control mechanism are connected in parallel and are then connected with the total starting push button in series; a temperature sensor, a temperature control resistor and a heating element are arranged in the heating control mechanism; the temperature controlresistor and the heating element are connected in series; the temperature sensor and the temperature control resistor are connected through electric signals; a granulator current transformer is arranged in the granulator control mechanism; a variable-frequency speed regulator is arranged in the feeding machine control mechanism. When the main motor current flowing through the granulator exceeds the design upper limit threshold value, a self recovery overcurrent protection device automatically switches off the power supply; after the machine overhaul is completed, and the fault is eliminated,the circuit is automatically recovered. The system has the advantages that the constant heating interval can be maintained; the two-way regulation on the motor rotating speed of a feeding small augermotor according to the current intensity can be realized; the whole machine capacity is maintained; meanwhile, the protection effect is achieved on the granulator per se.

Description

technical field [0001] The invention relates to a biomass pellet machine, in particular to an application control system for a straw biomass pellet machine. Background technique [0002] Biomass fuel refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste, and the biofuel made from waste is environmentally friendly and pollution-free. [0003] The development of foreign briquettes is divided into three stages. From the 1930s to the 1950s was the stage of research, demonstration, and cross-introduction. The focus of research was to replace fossil energy. Larger, renewable biomass energy has generated interest, and research on biomass compact briquettes has been carried out. By the 1990s, some countries in Europe, America, and Asia had applied a large amount of biomass compact briquette fuel in the field of life. From the late 1990s to the present is the third stage. Countries led by Denmark have carried out research work on larg...

AI Technical Summary

Problems solved by technology

The biomass briquette fuel industry is characterized by the active participation of enterprises and the gradual strengthening of national guidance, but there are still problems of small production scale and waste of production capacity

[0005] Specifically, the biomass pellet machine in the prior art has no heating device, and the speed of the feeding motor of the pellet machine cannot be automatically adjusted in real time based on the current change of the main motor, so the maximum production capacity of the pellet machine cannot be guaranteed, which easily leads to insufficient production capacity Or waste of production capacity occurs, and at the same time, the stable operation ability of the equipment is not high, and the power consumption is large, the production capacity is low, and the practical range is low.
