Pressing device of dynamic biomass granulator

Abstract

The invention discloses a pressing device of a dynamic biomass granulator. The pressing device of the dynamic biomass granulator is composed of a pressure displayer, a height adjustment device, a support, a pressure measurement device, a pressing assembly and a gradienter. The pressing assembly is composed of a pressing wheel, a roller shaft, a roller base and a pressing wheel locking nut. One end of the roller shaft is mounted in a center hole of the roller base through a bearing, and the pressing wheel is arranged at the other end of the roller shaft. The pressing wheel is fixed to the roller shaft through the pressing wheel lock nut. The roller base is fixed above the support. The height adjustment device and the pressure measurement device are arranged between the upper surface of the support and the lower surface of the roller base. The gradienter is arranged right in the center of the top of the roller base. The pressure displayer is electrically connected with the pressure measurement device. The pressing device of the dynamic biomass granulator can solve the problems that due to improper adjustment of pressing force, discharging cannot be achieved, energy consumption is increased, a template is sharply abraded, the service life of the bearing is short and the pressing wheel is prone to breakage, and can also solve the problem that due to the fact that the pressing force is unbalanced, fatigue overloads and breakage of the main shaft are caused.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a compacting device of a dynamic mode biomass pellet machine. Background technique [0002] Biomass pellet machine is a kind of agricultural machinery. Through the biomass pellet machine, the agricultural and forestry waste can be mechanically pressurized, so that the original loose raw material without a certain shape can be compressed into a shaped fuel with a certain shape and a high density. There are many types of biomass pellet machines, such as ring die pellet machines, flat die pellet machines, hydraulic pellet machines, etc. The dynamic mode pellet machine belongs to the flat die pellet machine, and its template is a flat disc, which is covered with round holes. According to the different diameters of biomass particles, the commonly used hole diameters are 6mm, 8mm and 10mm. When the dynamic mode pellet machine is working, the template ...
