Vacuum spiral dryer

Abstract

The invention discloses a vacuum spiral dryer. The vacuum spiral dryer is characterized by comprising a drying box shell, wherein a spiral drying pipe is arranged on the inner side of the drying box shell, the top end of the spiral drying pipe penetrates through the top end of the drying box shell, extends to the outer side of the drying box shell and is fixedly connected with a piston type feeding pipe, the outer side of the piston type feeding pipe is connected with an outer sliding pipe in a sliding mode, and the outer sliding pipe is fixedly arranged at the position of the bottom end of afeeding and storage box. According to the vacuum spiral dryer, the piston type feeding pipe, a material blocking plate and the feeding and storage box are arranged, and a user puts materials to be dried into the feeding and storage box and closes a top end sealing cover, so that the problems that the vacuum spiral dryer needs to continuously feed materials after one drying process is finished whenthe vacuum spiral dryer is used, continuous feeding of the materials is not facilitated, and the use convenience of the vacuum spiral dryer is influenced are solved.

Description

technical field [0001] The invention belongs to the technical field of dryers, and in particular relates to a vacuum screw dryer. Background technique [0002] Dryers can be divided into industrial and civilian. Industrial dryers are also called drying equipment or dryers. Civilian dryers are one of washing machines. They are generally used to remove clothing and other textiles after washing and dehydration. of moisture. The dryer has several modes such as belt drying, drum drying, box drying, and tower drying; the heat source includes coal, electricity, gas, etc.; the drying process of materials has hot air flow type and radiation type, etc. , hot air drum drying is that the hot air flow moves forward from the tail, fully contacts with the material, and makes full use of the heat transfer through heat conduction, convection, and radiation; the heat energy is directly transferred to the material, so that the moisture of the material is continuously evaporated in the cylinde...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a vacuum screw dryer to solve the inconvenience of continuous feeding of materials when using the existing vacuum screw dryer, and the difficulty of preventing the heat of the heating dryer from spreading to the outside of the vacuum screw dryer motor, and at the same time it is difficult to reduce the noise of the vibrating motor
