Drying device, garbage treatment device and material machining method

Abstract

The invention discloses a drying device, a garbage treatment device and a material machining method. The drying device comprises a bin body with a feed port and a discharge port and further comprisestwo rotating shafts, a drying device and a heating device, wherein the two rotating shafts are arranged in the bin body in parallel, each rotating shaft is provided with a spiral conveying blade, thedistance between the two rotating shafts is larger than the linear distance between the edge of any spiral conveying blade and the rotating shaft where the spiral conveying blade is located and smaller than the sum of the linear distances between the two spiral conveying blades and the respective rotating shafts where the spiral conveying blades are located, the driving device drives the two rotating shafts to rotate around own axes, the rotating directions of the two rotating shafts are opposite, and the heating device is used for heating the interior of the bin body. According to the scheme,the two mutually-engaged spiral conveying blades are adopted for synchronous conveying, the driving force during conveying is effectively increased, the stable conveying requirement of crushed solidwaste with certain humidity and viscosity can be met, and the drying stability can be guaranteed beneficially.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a drying device, a garbage processing device and a material processing method. Background technique [0002] Garbage classification refers to the general term for a series of activities in which garbage is classified, stored, placed and transported according to certain regulations or standards, and then transformed into public resources. [0003] With the rapid development of my country's economy, garbage sorting has become a hot topic at present, and garbage sorting actions are being carried out in full swing across the country. [0004] As an important type of garbage, kitchen waste contains extremely high moisture and organic matter, and it is easy to rot and produce stench. After proper treatment and processing, it can be transformed into new resources. The high organic matter content makes it possible to be used as fertilizer and feed after strict...

Problems solved by technology

The current drying equipment, such as the structure disclosed in the application number 201520058535, uses a single screw conveying shaft to transport materials and realize heat conduction through a heat medium (oil or water). The single screw conveying structure is used for solid-liquid When transporting separated and pulverized food waste solids with certain humidity and viscosity, there is often insufficient power, resulting in reduced drying stability

[0006] In addition, oil and water are used to conduct heat to the U-shaped panel wall to realize heating. When drying, the oil and water need to be heated first to realize the heating of the U-shaped panel wall. It needs two heat conductions, which increases the heating time and The loss of heat conduction, and a certain amount of water, oil and other resources need to be wasted, which increases the drying cost and also increases the complexity of the equipment structure
