Composting reactor

Abstract

The invention discloses a composting reactor. The composting reactor comprises a roller device, a feeding device, a discharging device, a driving device, a stirring device and an automatic flow storage and humidification device, the device is mainly applied to parks, fallen leaves, grass clippings and the like in the parks are collected and directly added into the reactor to be subjected to on-site composting treatment, residents use the foot-operated fitness equipment to exercise, and generated power is used for driving the stirring shaft in the composting reactor to rotate. The stirrer is ofa novel screw rod type and comprises the stirring rods and the screw rods, the stirring rods comprise the long stirring rod and the short stirring rod, and the screw rods are sequentially and spirally arranged at the top end of the long stirring rod, so that materials are fully mixed in the axial direction and the radial direction. Meanwhile, the automatic flow storage and humidification device is arranged at the top of the reactor, the temperature and humidity change condition of the reactor body can be monitored in real time, and collected rainwater is used for humidifying the reactor body.

Description

technical field [0001] The invention discloses a solid waste aerobic composting reactor, in particular to a composting reactor for treating landscaping. [0002] technical background [0003] Landscaping waste mainly includes branches, fallen leaves, grass clippings, flower residues, etc. generated in urban greening. With the rapid development of urban greening, the total amount of landscaping waste is also increasing year by year. At present, most cities in my country mainly adopt two methods to deal with landscaping waste, that is, most of them are transported to the suburbs for landfill, and a small part is incinerated together with domestic waste. These two methods neither meet the requirements of environmental protection, but also waste money. [0004] In the composting process of the drum reactor, the material is placed in the horizontal drum, and the compost is fully mixed during the composting process through the agitation of the agitator, and the properties of each ...

AI Technical Summary

Problems solved by technology

Most of the current stirred reactors are paddle-type agitators with simple structure, but paddle-type agitators are mostly used for liquid mixing, and landscaping waste contains a large amount of leaves, grass clippings, etc., which will generate greater resistance to paddle-type agitation; in addition, The stirred reactor basically uses a motor to drive the stirring shaft in the drum to rotate to achieve the effect of turning over. This type of reactor relying on the motor has a complex structure, high cost, and limited space and power, so it is not suitable for large parks and green spaces.
