Circulating cooling system of biomass granulator

Abstract

The invention relates to the field of biomass granulators, and particularly relates to a circulating cooling system of a biomass granulator. The circulating cooling system of the biomass granulator comprises a main shaft, a pressing roller seat, a pressing roller device, an oil tank, a main oil way structure and a secondary oil way structure, wherein the main oil way structure comprises a main oil inlet way, a first main oil inlet, a first main oil outlet, a main oil outlet way, a second main oil inlet and a second main oil outlet; the secondary oil way structure comprises a secondary oil inlet way, a secondary oil inlet and a secondary oil outlet; the first main oil inlet communicates with an oil outlet pipe of the oil tank through a pipeline, the first main oil outlet communicates with the secondary oil inlet through a pipeline, the secondary oil outlet communicates with the second main oil inlet through a pipeline, and the second main oil outlet communicates with an oil return pipe of the oil tank through a pipeline. The circulating cooling system has the advantages of simple structure and convenience in operation, cold and hot circulating heat exchange is realized, the service life of a pressing roller bearing is prolonged, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of biomass pellet machines, in particular to a circulating cooling system for biomass pellet machines. Background technique [0002] In the field of existing biomass pellet processing technology, the pellet machine used to produce biomass pellets mainly includes a ring die, which is equipped with pressure rollers that are compatible with the ring die, and the pressure rollers are installed by roller bearings arranged at intervals. On the pressure roller bearing sleeve, there is a pressure roller bearing seal between the two ends of the pressure roller and the pressure roller bearing sleeve. The pressure roller bearing sleeve is set on the pressure roller shaft, and the pressure roller shaft is installed on the main shaft disk. on the spindle. When working, the external power is input from the ring die support to make the ring die rotate, the main shaft remains stationary, the material enters between the ring die and ...

AI Technical Summary

Problems solved by technology

[0003] Due to the high-strength extrusion and friction of the material, the temperature of the pressing chamber is high, even as high as 150°C, and the bearing of the pressing roller is not lubricated enough, which is likely to cause wear and consumption, and eventually cause the scrapping of the bearing, reduce the efficiency of work and production, and increase production costs.
