Novel rotary biological drying device

Abstract

The invention relates to a novel rotary biological drying device, and belongs to the technical field of biological drying. The device comprises a feeding device, a reverse stirring spiral piece, a forward stirring spiral piece, an aeration pipe, a rotary shell, a forward flow guide piece, a light material outlet, a heavy material outlet, an aeration air inlet, a water vapor outlet, an aeration tank, a left fixed end and a right fixed end. Radial and axial multi-direction mixing of materials is achieved in a reactor, and the defect that an existing rotary drum type biological drying device is poor in axial mixing performance is overcome. An aeration system can freely control the aeration time and the aeration amount according to the rotation speed of a cylinder body, and a control unit doesnot need to be independently arranged. Besides, the dynamic aeration system does not have the problem of aeration hole blockage. The device is simple in structure, large in treatment amount, good insealing performance and convenient to maintain, and the size of the device can be customized at will according to requirements.

Description

technical field [0001] The invention belongs to the technical field of biological drying, in particular to a novel rotary biological drying device. Background technique [0002] Biological drying is suitable for low-temperature drying treatment of various biomass materials due to its extremely high energy efficiency and mild drying temperature. 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 ...

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
