Roller dryer with knocking hammer

Abstract

The invention relates to a roller dryer with a knocking hammer. The roller dryer with the knocking hammer comprises a cylindrical outer shell and an inner ring. The inner ring is sleeved in the cylindrical outer shell, scattering cutters and breaking hammers are respectively arranged on the inner wall of the inner ring, a scattering device is arranged on the central portion of the inner cavity of the inner ring, and scattering teeth are arranged on the periphery of the scattering device. The roller dryer with the knocking hammer is simple in structure, has the function of automatically stirring materials, is heated evenly, and is thorough in grinding, the breaking hammers can knock and break up the materials attached to the inner wall of the inner ring in a rolling process, and full scattering and centrifugal drying continue to be carried out. The scattering cutters fully carry out scattering processing on wet materials entering the dryer, and the roller dryer with the knocking hammer improves working efficiency, reduces water content, and is suitable for the material drying of a medical industry, a chemical industry, a food industry and a feed industry.

Description

Technical field [0001] The invention relates to a dryer, in particular to a drum dryer with a percussion hammer. Background technique [0002] In the process of producing chemical raw materials or materials such as calcium carbonate, calcium hydrogen phosphate or calcium hypochlorite, the existing drying equipment is diverse, mainly tube dryers and drum dryers. The basic structure of the drum dryer is a cylinder, the center of which is provided with a main shaft, and the two ends are respectively provided with an inlet and an outlet. [0003] However, many materials to be dried have strong viscosity and are easy to stick into agglomerates, which brings many restrictions to the drying work. The drying temperature cannot be too high, and the materials to be dried cannot be locally overheated during the drying process. In existing equipment, the problem of material agglomeration and sticking to the inner wall of the dryer often occurs. Therefore, during the drying process, the mater...

AI Technical Summary

Problems solved by technology

[0003] However, there are many materials to be dried that are highly viscous and easily bonded into blocks, which brings many restrictions to the drying work. The drying temperature cannot be too high, and the materials to be dried cannot be partially overheated during the drying process.

In the existing equipment, the problem of material agglomeration and sticking to the inner wall of the dryer often occurs. Therefore, during the drying process, due to the uneven heating of the material to be dried, the production efficiency is low. After drying, the material contains more moisture and agglomerates Viscous phenomenon is serious
