Air cooled dedusting device for producing fine rubber powder by utilizing waste tires

Abstract

The invention discloses an air cooled dedusting device for producing fine rubber powder by utilizing waste tires. The air cooled dedusting device comprises a conveying pipe, a temperature reducing chamber, a storage chamber, an air blower, a dust storage temperature reducing chamber, and a kick-out device. One end of the conveying pipe is provided with a feed inlet. The temperature reducing chamber is arranged at the other end of the conveying pipe. The temperature reducing chamber is communicated with the storage chamber on the lower part of the temperature reducing chamber. The upper part of the temperature reducing chamber is communicated with the air blower. The dust storage temperature reducing chamber is arranged on the lower part of the air blower. With the adoption of the structure and process, except the feed inlet and feed outlet, the rest of the entire device forms a sealed system. The conveying pipe is designed in an ''S'' shape so that the feeding speed is slowed down and the temperature reducing effect is improved. Meanwhile, heat after temperature reduction and small amount of powder generated enter to the dust storage temperature reducing chamber together so as to reduce the temperature and dedust thoroughly, and therefore, quality problem of softened rubber powder and blocking and the like as well as the problem that dust pollutes the environment are solved.

Description

technical field [0001] The invention belongs to the technical field of chemical production, relates to the field of production equipment for producing fine rubber powder by using waste tires, and in particular relates to an air-cooled dust removal device for producing fine rubber powder by using waste tires. Background technique [0002] There are many production processes and technologies for producing rubber powder and fine rubber powder from waste tires, including: normal temperature method, liquid nitrogen freezing method, air expansion method, chemical additive method, water shock method and other technical methods. Processing technologies other than normal temperature production technology are not adopted due to unfavorable factors such as high safety risk factor, extensive environmental pollution and high manufacturing cost. Therefore, the processing technology using the normal temperature method is the first choice in China. Its processing technology is: waste tires...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to address quality defects such as product softening, agglomeration, and affecting the tensile strength of downstream regenerated rubber products due to incomplete cooling in the grinding process in the current process of using waste tires to produce rubber powder and fine rubber powder. And because the grinding particle size reaches 40-120 mesh, it will form a dust source, affect the environment and the health of employees and other disadvantages, and develop additional devices to achieve the purpose of eliminating the above defects
