A new type of rotary biological drying device

Abstract

The invention relates to a novel rotary biological drying device, which belongs to the technical field of biological drying. Including feeding device, reverse agitating helical piece, forward agitating helical piece, aeration tube, rotary shell, forward deflector, light material outlet, heavy material outlet, aeration inlet, water vapor outlet, Aeration tank, left fixed end and right fixed end. The radial and axial multi-directional mixing of materials is realized in one reactor, which overcomes the disadvantage of poor axial mixing performance of existing rotary drum biological drying equipment. The aeration system can freely control the aeration time and aeration volume according to the rotation speed of the cylinder, no need to set up a separate control unit, and the dynamic aeration system will not cause the problem of clogging of the aeration holes. The device has simple structure, large processing capacity, good sealing performance and convenient maintenance, and the size can be customized according to requirements.

Description

Technical field [0001] The present invention belongs to the field of biological drying, and is specifically a new type of rotary biological drying device. Background technique [0002] Biolidification is suitable for low temperature drying treatment of various biomass materials with its extremely high energy efficiency and mild drying temperature. However, traditional biological drying techniques have a mixed effect, long dry cycle, uneven dry effect, therefore requires a biological drying apparatus having excellent mixing performance and excellent drying effect. [0003] One biological drying apparatus for stacking the drying bed is disclosed in the disclosure of which is: 201520804626.8, is used to stack the drying bed of the dry matter; and a closed space of the drying bed and the drying bed forming a variable volume. Transparent shed; a groove of the liquid generated during the drying bed and used to collect the liquid generated during biological drying, and the technique is ...

AI Technical Summary

Problems solved by technology

However, the traditional biological drying technology has the problems of poor mixing effect, long drying cycle, and uneven drying effect. Therefore, it is necessary to develop a biological drying equipment with good mixing performance and excellent drying effect.

[0003] The prior art discloses a biological drying equipment with the application number: 201520804626.8, which is used to stack the drying bed of the material to be dried; it is located above the drying bed and forms a variable-volume closed space with the drying bed Transparent roof; a groove located on the wall of the drying bed and used to collect the liquid produced in the biological drying process. This technology uses hot air to dry the material, which is a purely physical thermal drying method, which can High power consumption, no mixing function, poor processing effect

[0004] The prior art discloses a biological drying equipment with the application number: 201820087206.6. Its structure includes a garbage bin, a steam outlet, a hot air outlet, a connecting plate, an electric heater, a chassis, a lock, a door, a control button, a display screen, and a control panel. Panel and top cover, this technology adopts hot air and electric heating wire coupling drying method, which improves the drying effect compared with pure hot air, but the drying method does not change in essence, and then uses physical heat drying method, which consumes more energy. No stirring function is configured, and the processing effect is poor
