specific Embodiment approach 1

[0020] Specific implementation mode one: combine figure 1 with figure 2 Describe this embodiment, a kind of aerobic composting reactor that is used for processing household waste in severe cold area of ​​this embodiment comprises frame body 17 and a plurality of rollers 27, and a plurality of rollers 27 are installed in the lower end of frame body 17, and described aerobic The composting reactor also includes a reactor temperature control box 20, a rotating bracket 29, an insulation layer 5, a motor 12, a gas flow meter 11, an air compressor 19, a columnar reactor tank body 18, a resistance wire temperature control box 32, and an inner shaft 8 , an outer shaft 7, a first temperature sensor 1, a second temperature sensor 10, a third temperature sensor 14, a plurality of stirring paddles 6 and two electrode plates 28,

[0021] The reactor temperature control box 20 is installed on one side of the frame body 17, the air compressor 19 is installed on the other side of the frame ...

specific Embodiment approach 2

[0031] Specific implementation mode two: combination figure 1 with figure 2 To illustrate this embodiment, the columnar reactor tank body 18 of this embodiment is further provided with a vertical leachate discharge port 26 and a vertical leachate return port 24 . So set, the effect of the vertical exhaust port 24 is: to exhaust when the reactor is vertical. The function of the vertical leachate outlet 26 is to flow out the leachate when the reactor is vertical. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0032] Specific implementation mode three: combination figure 1 with figure 2 The present embodiment will be described. The thermal insulation layer 5 of the present embodiment is a polyurethane thermal insulation layer. With such setting, the heat preservation effect is good. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

[0033] Specific implementation mode four: combination figure 1 with figure 2 Describe this embodiment, the diameter of the small hole opened on the inner shaft 8 and the outer shaft 7 of this embodiment is 3mm-8mm. When in use, the optimal diameter of the small hole is 5mm. Such a setting is convenient for air intake or water supply of the inner shaft. Other compositions and connections are the same as those in Embodiment 1, 2 or 3.

Abstract

The invention discloses an aerobic composting reactor used for treating household garbage in a severe cold area and relates to an aerobic composting reactor. The aerobic composting reactor aims at solving the problems of low conversion rate of household garbage composting finished products and small treatment amount caused by poor heating and heat preservation effects and non-uniform ventilation and oxygen supply of the existing composting reactor. According to the aerobic composting reactor, an electromotor and a columnar reactor tank body are mounted on a rotary bracket side by side, a reactor temperature control box is connected with the columnar reactor tank body, an inner shaft is eccentrically and axially arranged inside the columnar reactor tank body in a penetrating manner, an outer shaft sleeves the inner shaft, the electromotor is connected with the outer shaft, a plurality of small holes are formed in the inner shaft and the outer shaft, a plurality of stirring paddles are annularly mounted on the outer shaft, an air compressor is connected with the inner shaft through a gas flowmeter, two electrode plates are mounted on two end surfaces of the columnar reactor tank body and thermal-insulation layers are mounted on outer walls of two end surfaces of the columnar reactor tank body. The aerobic composting reactor is used for treating household garbage in the northern severe cold area.

Description

technical field [0001] The invention relates to an aerobic composting reactor, in particular to an aerobic composting reactor used for processing domestic garbage in severe cold regions. Background technique [0002] Organic domestic waste composting technology is an effective method to deal with organic domestic waste. It uses microorganisms such as bacteria, fungi and actinomycetes existing in domestic waste or natural soil to make domestic waste undergo a series of biochemical reactions and be composted. Degrades to form a humus-like soil that is used as a fertilizer to improve the soil. The organic aerobic composting reactor has the characteristics of short fermentation period, fast heating, controllable temperature of the pile body, good heat preservation effect, complete degradation of organic matter, uniform stirring, and free movement. [0003] In my country, sanitary landfill and incineration are the main ways to deal with domestic waste. However, due to the large ...
