Problems solved by technology

Because: a. The conveyor belt of the belt conveyor is made of polytetrafluoroethylene, and the maximum drying temperature of the material cannot exceed 180 degrees Celsius. When the temperature exceeds this temperature, the conveyor belt will be deformed and elongated, and it will slip or burn out, which can only meet the requirements of free water drying. Requirements, cannot meet the requiremen...

Abstract

The invention discloses a high temperature resistant microwave belt drying kiln, which comprises a belt conveyor (1), a microwave suppressor, a microwave cavity (3), an exhaust system (4), a microwave energy feeding system (5), a temperature measuring System (6) and control system (7), described belt conveyor (1) is made up of conveyer belt, stainless steel mesh belt (10), shaft (11), idler roller (12) and driving device (13), The conveyor belt is a ceramic fiber cloth conveyor belt (9) with a thickness greater than 20mm, the stainless steel mesh belt (10) is in good electrical contact with the drive device (13) and is well grounded, and the idler roller ( 12) The material is ceramic material, the material of the shaft (11) is stainless steel, the shaft (11) is in good contact with the cavity of the microwave oven (3) and can conduct electricity. The invention is a high-temperature-resistant microwave belt drying kiln that can meet the requirements of dematerialized crystallization water or structural water. It can withstand high temperatures > 500 degrees Celsius, has high equipment stability, long service life and simple structure, and can be widely used in the drying of materials. Dry dehydration, including free dehydration and structural dehydration.

Description

technical field [0001] The invention relates to a drying kiln, in particular to a high temperature resistant microwave belt drying kiln. Background technique [0002] Microwave is known as "the second flame of human beings". Because water is a strong polar molecule and has a strong ability to absorb microwaves, the application of microwave drying and dehydration equipment has developed rapidly in recent years. At present, the structure of the microwave belt drying kiln on the market is mainly composed of a belt conveyor, a microwave cavity, a microwave suppressor, a microwave energy feeding system, an exhaust system, and a control system. Because: a. The conveyor belt of the belt conveyor is made of polytetrafluoroethylene, and the maximum drying temperature of the material cannot exceed 180 degrees Celsius. When the temperature exceeds this temperature, the conveyor belt will be deformed and elongated, and it will slip or burn out, which can only meet the requirements of fr...
