Inner layer roller with auxiliary scattering grids

Abstract

The invention relates to an inner layer roller with auxiliary scattering grids. The inner layer roller comprises a cylinder body, a material lifting plate and a material guiding plate, wherein the material lifting plate and the material guiding plate are arranged inside the cylinder body. A plurality of auxiliary scattering grids protruding toward the center of the roller are arranged in the middle section of the cylinder body. The auxiliary scattering grids include two square grid plates, the bottom edges of the two grid plates are respectively connected with the inner wall surface of the cylinder body, and the upper edges of the two grid plates are connected together. According to the inner layer roller with the auxiliary scattering grids, the auxiliary scattering grids are added to theinner wall of the inner layer roller to achieve preliminary crushing of some large pieces of materials through the auxiliary impact of the scattering grids, and then the crushed materials are leaked to scattering shafts for crushing. On one hand, the crushing efficiency of the materials is improved; on the other hand, some large pieces of materials can be collected in the interior of the auxiliaryscattering grids and be rolled repeatedly in the auxiliary scattering grids with the rotation of the roller until large blocks become small blocks, and steel ribs and transverse ribs of the grids play a supporting role in the crushing.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to an inner layer cylinder with auxiliary grid breaking. Background technique [0002] For drum dryers, in order to solve the problem of material lifting and movement, structures such as lifting plates and material guide plates are generally installed on the inner wall of the drum. The specific structural shapes of the material lifting plates and material guide plates, and the For the arrangement inside the drum, please refer to the patent No.: 200620031704.6, title: single-stage drying drum, multi-stage drying drum and its new high-humidity material dryer. [0003] In recent years, in order to further improve the drying effect, there is also a breaking shaft in the middle of the drum. The existing lifting plate itself can only be used as a part to carry the lower material upwards, and has no assistance in crushing the material itself. function, and the dryer from the insi...

Problems solved by technology

[0003] In recent years, in order to further improve the drying effect, there is also a breaking shaft in the middle of the drum. The existing lifting plate itself can only be used as a part to carry the lower material upwards, and has no assistance in crushing the material itself. function, and the dryer from the inside to the breaking shaft can only disperse the materials, and does not have the function of lifting materials. After some materials enter the drum, their size is still relatively large, and they will be lifted during the process of turning over with the drum. The plate is brought to a high place, and then it falls directly from the height to the breaking shaft in the center of the drum, which is a great threat to the breaking shaft, and this problem needs to be solved
