Problems solved by technology
However, with the continuous progress of industrial technology, the requirements for equipment are getting higher and higher. Since the material is heated, evaporated and dried by the jacket outside the cylinder, and the stirring spindle and rake teeth in the center of the cylinder have no heating source, it is difficult for some thermally sensitive materials. High materials are easy to stick on the main shaft and rake teeth, which reduces the efficiency of equipment use and increases operating costs

The invention relates to a rake dryer with an internal heating shaft and a rake tooth. The original solid spindle of the rake dryer is changed into a sleeve hollow spindle, a cavity is formed in a rake tooth arranged on the spindle to form a hollow rake tooth, a steam pipe is arranged in the cavity, the shaft end of the sleeve hollow spindle is provided with a rotating joint, one end of the steam pipe is communicated with the rotating joint, and a heating medium can enter the steam pipe through the rotating joint at the shaft end and enters the cavity of the rake tooth and the sleeve hollow spindle through an opening of a steam branch pipe, so that the aim of heating the spindle and the rake tooth is fulfilled, and materials with high heat sensitivity are prevented from being adhered to the spindle and the rake tooth.
Description
Technical field: [0001] The rake dryer with internal heating shaft and rake teeth belongs to the technical field of chemical equipment, and is mainly used in the process of concentration and drying in chemical, food, pharmaceutical, environmental protection and other industries. Background technique: [0002] The dryer is widely used in chemical, food, pharmaceutical, environmental protection and other industrial fields. It is especially suitable for drying paste materials that are not resistant to high temperature, flammable, and easily oxidized at high temperature. It has simple structure, convenient operation, long service life, Stable and reliable performance, strong applicability. It uses the rotating main shaft to drive the rake teeth to evenly distribute the material in the cylinder on the cylinder wall, heat the material on the inner cylinder wall through the steam in the jacket, evaporate the water in the material, and vacuum the gas in the cylinder Discharge, so a...
