Rubbish drying machine

Abstract

The invention discloses a trash dryer which is characterized by comprising a feed hopper (2), a discharge nozzle (16), a material delivery pipe (3), a microwave cavity (4), a microwave generator (5), an air distribution pipe (17), an air inlet pipe (8), an air outlet pipe (7) and a heat pump (9); wherein, the material delivery pipe (3) is arranged in an oblique way, a feed end of the material delivery pipe (3) is connected with the feed hopper (2), a discharge end penetrates the microwave cavity (4) to be connected with the discharge nozzle (16), at least one microwave generators (5) are arranged in the microwave cavity; the body of the air distribution pipe (17) is provided with more than one air outlet holes, one end of the air distribution pipe (17) is inserted into the material delivery pipe (3), the other end thereof is connected with the heat pump (9) by the air inlet pipe (8), one end of the air outlet pipe is connected with the discharge nozzle (16), the other end thereof is connected with the heat pump (9). In the invention, the heat pump drying technology and the microwave drying technology are integrated for drying solid trash; in addition, the trash dryer of the invention can reduce energy consumption, carry out drying in a rapid manner, kill microorganism and eliminate environmental protection in the process of drying.

Description

technical field [0001] The invention relates to a garbage dryer. Background technique [0002] Household waste contains 50-85% water, and the water needs to be dried in the process of domestic waste reuse. The traditional drying method puts domestic waste into the drying room, then sends hot dry air into the drying room, absorbs the moisture of the domestic waste, and then directly discharges it into the atmosphere. The discharged hot and humid air contains a large amount of latent heat or thermal energy, resulting in energy utilization. low rate. Contents of the invention [0003] The purpose of the present invention is to use microwave drying technology and heat pump drying technology in combination to improve drying efficiency, reduce drying energy consumption, reduce the total amount of garbage bacteria, and eliminate the air pollution of the surrounding environment during the drying process. [0004] The invention includes a feed hopper, a discharge pipe, a material...
