Feeding device used for granulator

Abstract

The invention discloses a feeding device used for a granulator. The feeding device used for the granulator comprises a grading material stirring mechanism, a helical feeding shaft controlling feeding quantity and a vibration screen enabling feeding to be uniform. When a motor 1 rotates, the grading material stirring mechanism and the helical feeding shaft are driven to rotate. The quantity of material falling onto a template is controlled by controlling the rotating speed of the helical feeding shaft. The vibration screen with a certain aperture is added between a helical feeding port and the template, and the vibration screen vibrates in a rotating mode and then enables the material to disperse on the template evenly. Compared with the prior art, the feeding device used for the granulator has the following advantages that by means of helical drive, the feeding quantity can be controlled conveniently and fast according to the need of production, so that the phenomena of overloading and material blocking are avoided and the possible problem that the motor is damaged is avoided; through the vibration screen, the material falling onto the template is dispersed evenly, the contact area of the material is increased, and the yield of granulator is increased; and meanwhile, the density of forming particles is uniform because of the uniform distribution of the material and the quality is controlled effectively.

Description

technical field [0001] The invention relates to the field of pellet machines, in particular to a feeding device for pellet machines. Background technique [0002] With the sharp decline of fossil fuels, the sustainable development of human society is seriously threatened. Therefore, biomass, as a renewable and clean energy source, has attracted widespread attention from the society. For my country, a large agricultural country, how to rationally and efficiently utilize the large amount of biomass waste such as straw produced every year has become another focus. Extruding fluffy biomass chips into pellets is one of the means. The feeding of the pellet machine is an important link in the realization of material molding. This link affects the speed and quality of pellet molding, and has an important impact on the subsequent use of pellets. [0003] The existing pellet machine feeding device is often unable to control the amount of biomass debris falling on the formwork, whic...
