Three-level drum type wet material drying machine

Abstract

The invention discloses a three-level drum type wet material drying machine which comprises a base frame, an outer-side drum, a middle-layer drum, an inner-layer drum, end covers at the two ends and acenter scattering shaft. The outer-side drum, the middle-layer drum and the inner-layer drum are sequentially and concentrically arranged together in a sleeved manner. The outer surface of the outer-side drum is supported on a carrier roller of the bottom frame, and the lower portions of the end covers at the two ends are connected to the bottom frame. The end covers are arranged at the end portions of the outer-side drum in a sealed and sleeving manner. By means of the three-level drum type wet material drying machine, an auxiliary scattering grid is additionally arranged on the inner wall of the inner-layer drum so that part of bulk materials can be preliminarily smashed through auxiliary impacting of the scattering grid, and then the broken materials leak to the scattering shaft to bebroken. By means of the three-level drum type wet material drying machine, wet materials can be cut, in addition, elastic rib plates are further additionally arranged on the two sides of a cutter, materials falling from the drums can be rebounded, part of the materials are promoted to reciprocate between the inner walls of the drums and the scattering shaft, and the scattering effect is improved.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a three-stage drum type dryer for viscous and wet materials. Background technique [0002] Three-stage material drum dryer, in order to solve the problem of material lifting and movement, generally there are structures such as lifting plates and material guide plates on the inner wall of the drum, the specific structural shape of the material lifting plates and material guide plates , and the arrangement inside the drum can refer to the patent number: 200620031704.6, title: single-stage drying drum and multi-stage drying drum and the description of the invention patent of the 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. After some materials enter the drum, their size is still relatively large, and they will be taken to a high place by the lifting plate ...

AI Technical Summary

Problems solved by technology

[0004] Various forms of breaking shafts, such as extended shafts and multi-axis combined use, developed by our company in the past few years, are all for timely breaking up materials in the drum, so that they can more fully contact with hot air and improve the drying effect. The structure of the dispersing shaft in the prior art is relatively fixed, and the dispersing functional parts on the dispersing shaft will wear or deform after long-term use, and the later maintenance and replacement are not very convenient. In addition, the breaking shaft is only responsible for the crushing of materials, and does not have other auxiliary functions, which needs to be improved.
