An automatic integrated composting device

Abstract

The invention provides an automatic integrated composting device, which comprises: a raw material mixing module (1), a fermentation tank and a composting product delivery module are sequentially connected through pipelines, and the device performs automatic integrated composting operation under the control of the mixture composting process control module, and the raw materials The mixing module (1) includes: a raw material input port, a mixing bin and a pumping device, the raw material input port includes a sludge feed port (12) and an agricultural straw feed port (13), and the fermentation tank includes a fermentation tank body (5) And a porous drawer-type sludge fermentation platform (8) with a fermentation platform mesh plate (14), the composting process control module includes: a temperature sensor and an oxygen sensor arranged on the top of the fermentation box body (5), normal temperature air supply equipment , high-temperature air supply equipment, toxic gas treatment device (10), fermentation process control unit, compost product output module including: conveyor belt baffles (6) fixed on both sides of the bottom of the fermentation box (5) and conveyor belts (9) installed on the bottom of the box ).

Description

technical field [0001] The invention relates to the field of solid waste disposal and resource utilization, in particular to an automatic integrated composting device for aerobic composting of municipal sludge and agricultural straw mixture. Background technique [0002] Sludge is an accessory after sewage treatment. It is rich in nitrogen, phosphorus, potassium and organic matter. It is a good organic fertilizer resource. After soil application, it can significantly increase soil fertility and improve soil physical properties; on the other hand, sludge contains many Toxic and harmful substances (such as parasites, pathogenic microorganisms, heavy metals, flocculants) and unstable organic substances, if not properly treated and disposed of, will cause direct or potential pollution to the environment. Sludge composting is one of the most effective ways to treat urban sludge as a resource. Composting sludge can kill pathogenic bacteria, explain organic pollutants, and change t...

AI Technical Summary

Problems solved by technology

At present, the initial mixing of sludge composting is mostly carried by a loader or manually transferred to the fermentation tank, and there is a risk of the mixture spilling and the odor escaping and polluting the environment; the current composting process is done manually or mechanically, which requires a large investment in manpower and equipment ; The current fermentation tank only pumps oxygen at room temperature. When the fermentation tank is low temperature, the temperature of the fermentation tank cannot be adjusted, which is not conducive to the rapid progress of the fermentation process; in the prior art, the fermentation products are transported out by dump trucks or the compost products in the hopper are transferred to trolleys This process will bring secondary pollution, increase additional manpower and equipment costs, and is not conducive to the automation of the composting process
