Horizontal type closed strong-drying device for town waste

Abstract

The invention discloses a horizontal type closed strong-drying device for town waste, and belongs to the technical field of town waste treatment. The device comprises a closed drying box body, whereinthe top of the drying box body is provided with a closed feeder, and a closed discharger is arranged at the bottom of the drying box body; a hollow stirring shaft is coaxially and rotationally connected in the drying box body, and a plurality of hollow stirring rods are uniformly arranged on the stirring shaft; a hollow cavity in the stirring rod communicates with the hollow cavity in the stirring shaft; a plurality of air nozzles are uniformly arranged on the stirring rod; both of the two ends of the stirring shaft extend out of the drying box body; a power mechanism used for driving the stirring shaft to rotate is in transmission connection with one end of the stirring shaft, an air valve is rotationally connected to the other end of the stirring shaft in a sealing mode, and a hot air source is connected to the air valve; and thus, the horizontal type closed strong-drying device for the town waste is energy-saving and environment-friendly, high in drying degree and high in drying efficiency, and the waste can be directly used for smoldering pyrolysis treatment of a next process flow after being dried.

Description

technical field [0001] The invention belongs to the technical field of urban garbage treatment, in particular to a horizontal airtight and powerful drying device for urban garbage. Background technique [0002] The urban waste after sorting and crushing is mainly flaky and granular solid waste, which needs to be dried before recycling. At present, natural drying or ordinary heating and drying are mainly used. The drying efficiency of these two methods is If the dryness is not high enough, it will not be conducive to the subsequent smoldering pyrolysis treatment, which will affect the processing speed and processing capacity of urban waste. Contents of the invention [0003] The object of the present invention is to provide a kind of urban garbage horizontal airtight powerful drying device, so that the garbage can be directly used for further smoldering pyrolysis treatment after drying treatment; the technical scheme adopted for achieving the above-mentioned purpose is: ...

AI Technical Summary

Problems solved by technology

[0002] The urban waste after sorting and crushing is mainly flaky and granular solid waste, which needs to be dried before recycling. At present, natural drying or ordinary heating and drying are mainly used. The drying efficiency of these two methods is Low and often incomplete drying, which cannot reach the dryness for storage and reuse. If the dryness is not high enough, it will not be conducive to the subsequent smoldering pyrolysis treatment, which will affect the processing speed and processing capacity of urban waste
