Drying device using gas as heating source

Abstract

The invention discloses a drier using gas as heating source, which includes material drying barn, the character lies in: the cone of the barn is connected to a hot wind supplying system; the hot wind uses gas media as heating source, the lower part cone aperture of the barn is connected to a material carrying system. The invention has merits of quick heating, the utilization rate of heat is high.

Description

technical field [0001] The invention relates to a drying process and its equipment, in particular to a drying device which uses gas to heat air and uses the hot air to dry raw materials for products such as plastics, nylon, rubber and regenerated materials. Background technique [0002] Raw materials such as plastic, nylon, rubber and recycled materials must be dried and pretreated before being processed. The existing drying pretreatment usually adopts direct hopper drying bin drying, and its structural form is that a cone-shaped hopper bin is equipped with an electric heating component, and the upper end surface of the hopper bin is a feeding port. The raw materials after electric heating and drying enter the product making machine directly from the outlet of the hopper. The direct-type hopper drying bin with this structure has poor drying performance, and moisture remains in the drying raw materials, and plastic and other products produced by the product molding machine a...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the problems of air bubbles and unstable quality in the existing direct-type hopper drying and bin-type drying, especially the use of electric heating for drying, which consumes a lot of power and high production costs, and at the same time, in order to save electric energy, more The purpose of this invention is to provide a raw material drying device that uses gas as a heating source to heat air, and uses hot air to dry plastic, nylon, rubber, and recycled materials.
