Three-return trip roller dryer with automatic adjusting structure and working method thereof

Abstract

The invention discloses a three-return trip roller dryer with an automatic adjusting structure and a working method thereof. The three-return trip roller dryer comprises a cylinder, a feed port, rolling rings arranged on the cylinder at equal intervals, a driving mechanism for driving the rolling rings to rotate, and an adjusting mechanism positioned at the bottom end of the cylinder and used foradjusting the cylinder; through startup of a second motor, a first support plate can be finally driven to move in the vertical direction, so that the cylinder moves along with the first support plate;when the cylinder drives insulation materials to rotate, the cylinder moves along with the first support plate, so that the insulation materials in the cylinder can always change the contact surfaceswith drying hot air currents conveyed by a drying air box, and the insulation materials are fully contacted with the hot air currents; a lot of the insulation materials to be dried are approximate indrying degree, so that the drying time of the insulation materials is accelerated; and the insulation materials are also approximate in drying humidity reached during drying, so that the drying efficiency of the insulation materials is greatly improved.

Description

technical field [0001] The invention relates to the field of dryers, in particular to a three-pass tumble dryer with an automatic control structure and a working method thereof, belonging to the technical field of drying application of thermal insulation materials. Background technique [0002] Insulation materials generally refer to materials with a thermal coefficient less than or equal to 0.12. During processing, compression is required to form the desired shape, so the insulation material needs to be dried before compression. Commonly used dryers include belt drying, Tumble drying, etc. The three-pass drum dryer is often used to dry insulation materials within a certain humidity range. The traditional three-pass drum dryer is generally composed of a cylinder and a rolling ring. When installing, the traditional three-pass drum The bottom of the dryer needs to be fixed on the foundation. When drying the insulation material, because the bottom is fixed, it is impossible to ...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a three-pass tumble dryer with an automatic control structure and its working method, so as to solve the problem that the bottom of the traditional three-pass tumble dryer needs to be fixed on the concrete foundation. When drying, because the bottom end is fixed installation, it is impossible to change the contact area between the insulation material and the oven airflow by adjusting the angle of the cylinder, resulting in the traditional three-pass tumble dryer with a large drying task. The drying efficiency is low, which cannot meet the needs of use, and the traditional three-pass drum dryer does not pre-treat the insulation material when it is used. When the humidity of the insulation material is high, it takes a long time to dry. Technical issues with low dry efficiency
