Granulator for cork granule production

Abstract

The invention relates to the technical field of cork granule production, and discloses a granulator for the cork granule production. The granulator comprises a machine body, a crushing mechanism, a granulating mechanism and a screening box, the crushing mechanism is arranged in the machine body, and the granulating mechanism is arranged at the lower end of the machine body. According to the granulator for the cork granule production, a servo motor is started to drive a fourth rotating shaft to rotate, so that a screening net barrel is driven to rotate, cork granules falling at the left end in the screening net barrel are rotationally screened, small cork granules fall to the bottom in the screening box along with rotation of the screening net barrel, large cork granules roll to the right end of the screening net barrel and roll out along with the rotation of the screening net barrel, if the cork granules are clamped in meshes of the screening net barrel and rotate to the topmost end along with the screening net barrel, the cork granules fall out of the meshes due to gravity, the phenomenon that a screening net is blocked cannot be caused, the efficiency is high, the screening net does not need to be manually cleaned at regular time, and the labor amount is reduced.

Description

technical field [0001] The invention relates to the technical field of cork pellet production, in particular to a granulator for cork pellet production. Background technique [0002] Cork is not wood but the bark of oak trees. Oak is a special tree species that matures at about 25 years old. After that, the bark is stripped every nine years. Not only will the collected oak not die, but it can also grow new bark. Oak is one of the oldest existing tree species in the world. Cork fiber, the main component of cork, is composed of dead cells in the shape of 14-sided polyhedron. Under the microscope, each cubic centimeter of cork contains about 40 million cells. The spaces between the cells are filled with an almost air-like mixture of gases. The vast majority of each cell is also gas, mainly air without carbon dioxide, forming airtight air pockets. When subjected to external pressure, the cells will shrink and become smaller, and the air pressure in the cells will increase; wh...

Problems solved by technology

[0003] The internal particle screening process of the existing granulator uses a vibrating device to drive the screening plate for screening. This method tends to cause large particles to be stuck inside the mesh of the screen, which is easy to cause blockage. Currently, the blockage is often cleaned.
