Biomass tooth mould pellet press

Abstract

The invention relates to machinery, and in particular relates to a biomass tooth mould pellet press. The biomass tooth mould pellet press comprises a rack (1) and extruding gears (2) which are mutually engaged, wherein the extruding gears (2) are barrel-shaped; and an intertooth space through hole (9) is arranged between gear teeth (3) or the two sides of the gear teeth (3) are provided with tooth side through holes (10). The biomass tooth mould pellet press is characterized in that gear shafts (5) of the extruding gears (2) which are mutually engaged are further connected with mutually-engaged pressure-reduction gears (6) in series. The biomass tooth mould pellet press has the beneficial effects that positioning gear teeth determine a gap between every two extruding gears so that the working stability is guaranteed; and meanwhile, a large part of a transmission torque is borne and the difficulty that a tooth mould is easily damaged is solved. Other auxiliary structures are adopted so that various disadvantages of existing machines and tools are solved; a tooth mould granulation machine achieves the aims of high production efficiency, small energy consumption and low cost, has the conditions of popularization and application and is expected to replace existing other machine types to be main push equipment of biomass grain fuel; and the biomass tooth mould pellet press has the important meanings to sufficient utilization of biomass resources including crop straws, grass and trees and the like, coal power conservation, and increasing of rural income.

Description

technical field [0001] The invention relates to a machine, that is, a biomass tooth mold granulator. Background technique [0002] In recent years, the level of rural electrification has increased significantly, and the consumption of straw fuel has plummeted. At the same time, with the successful promotion of agricultural dense planting technology and the increase of grain production, the output of crop straw has also increased significantly. Crop stalks require cost for transportation and space for stacking, and they are the main host carrier of diseases and insect pests in the coming year. Therefore, many farmers have to focus on burning straw in the wild, which not only wastes energy, but also causes air pollution, and even causes fires and aviation accidents. On the other hand, with the rapid advancement of my country's industrialization process, coal power is becoming increasingly tense. In this case, the biomass materials such as crop stalks and vegetation are crus...

Problems solved by technology

However, it is difficult to control the gap between the gears of the existing tooth mold pellet machine. If the gap is too large and the pressure is not enough, if the gap is too small, the gear shaft will bend and deform and cause failure.

In addition, due to the multiple through holes on the gear, the strength has been greatly reduced and it is easily damaged, which has become a difficult problem for the promotion and application of the tooth die pellet machine

In addition, there are also problems such as the accumulation of materials at both ends of the gear and at the root of the tooth, and the long time for the compressed particles to dissipate heat, which are also negative factors restricting the tooth-die pellet machine.
