Household garbage drying device

Abstract

The invention relates to a household garbage drying device. The household garbage drying device sequentially comprises a garbage feeding mechanism, a pretreatment mechanism, a transfer mechanism, a drying mechanism and a discharging mechanism, wherein the pretreatment mechanism comprises a movable crusher and a crushed garbage storage bin below the crusher; the garbage feeding mechanism is a first crane grab arranged on a crane track; the transfer mechanism is a second crane grab arranged on the crane track; the drying mechanism comprises a plurality of drying bins; a flip type drying film is arranged on each drying bin; height sensors and a plurality of temperature and humidity detection devices are arranged inside the drying bins; air supply fans are arranged on one side of the drying bins; the discharging mechanism is a third crane grab arranged on the crane track. According to the household garbage drying device disclosed by the invention, the moisture content of the household garbage is reduced to a low level in a small site and short time and under low energy consumption, stable material properties are provided for a subsequent treatment process, and the subsequent treatment implementing efficiency is improved.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to a domestic garbage drying device. Background technique [0002] There are many ways to reduce, harmless and recycle existing domestic waste. Most of the treatment methods have certain requirements for controlling the moisture content of materials. For example, reducing the amount requires reducing the moisture content to achieve reduction; none Harmfulization needs to reduce the activity of organic waste to achieve the characteristics of stable material properties (the principle of biological drying is to control the various reactions of organic matter to realize the absorption, evaporation of water and organic components); resource utilization needs to reduce the moisture content to achieve Prepare SRF fuel, incinerate power generation, etc. [0003] The control methods for the moisture content of domestic waste usually include: classification of dry and wet waste at the source...

AI Technical Summary

Problems solved by technology

[0003] The control methods for the moisture content of domestic waste usually include: classification of dry and wet waste at the source, centralized collection in the waste buffer area of ​​the treatment plant for natural drying, drying and drying with an external heating source, etc. Among the above control methods, source control is the most effective Thorough, but the cost of social implementation is huge, the implementation period is long, and it takes one or several generations of efforts to realize it; natural drying needs to occupy a large amount of space and increase construction costs. At the same time, the odor and sewage in the natural drying process are still Additional treatment is required, resulting in secondary pollution; the use of external heating sources consumes a lot of energy, resulting in a huge waste of energy
