Problems solved by technology

At present, domestic and international rotary drum microwave heating equipment is generally a normal-pressure drying equipment, and the interior cannot isolate the air from contacting the material. In this way, for products with dangerous gases that cannot be in contact with the air, it is easy to catch fire or even explode. , the rotary drum equipment cannot be used to operate, and the microwave source of the existing rotary drum is only fed from one direction, the microwave field is not uniform, and the heating efficiency is low

Abstract

The invention discloses a vacuum type microwave rotary roller drying device. The drying device comprises a sealed box body (6), a rotary roller (1) mounted in the sealed box body (6), sealing covers (2) mounted at the two ends of the rotary roller (1) and a material inlet opening (9) formed in one end of the rotary roller (1); microwave feed openings (3) are formed in the axial direction and the radial direction of the rotary roller (1), and are connected with a microwave generator (12), and the rotary roller (1) is driven by a motor (11) to rotate; a vacuum exhaust opening (5) and a material discharging opening (8) are formed in the rotary roller (1), and the vacuum exhaust opening (5) is connected with a condenser; and the condenser is connected with a storage tank. The drying device is reasonable in design and convenient to operate, under the vacuum negative pressure, axial and radial microwave heating is adopted, flammable substance is prevented from combusting and exploding, the safety performance is good, the heat utilization efficiency is high, the heating work efficiency is high, and the application range is quite wide.

Description

technical field [0001] The invention belongs to the technical field of microwave energy application, and in particular relates to a vacuum type microwave rotary drum drying equipment used for material drying, dry distillation and evaporation. Background technique [0002] Microwave technology has the characteristics of low energy consumption, short reaction time, simple operation, and increased yield of reactants, etc., and has been widely used. At present, the domestic and international rotary drum microwave heating equipment is generally a normal-pressure drying equipment, and the interior cannot isolate the air from contacting with the material. In this way, for products with dangerous gases that cannot be in contact with the air, there are dangers of fire or explosion. , can not be operated by rotary drum equipment, and the microwave source of the existing rotary drum is only fed from one direction, the microwave field is not uniform, and the heating efficiency is low. ...
