Automatically-expandable film covering aerobic-composting device

Abstract

The invention provides an automatically-expandable film covering aerobic-composting device, which comprises a fermentation cabin and an automatically-expandable film covering system above the same. The top of the automatically-expandable film covering system is provided with two-layer erection rods connected with vertical columns on two sides, a semi-permeable film is fixed to the erection rods and the vertical columns on two sides, erection rod diagonal supports are arranged between the two-layer erection rods, the vertical columns are connected through stretchable scissor frames, rollers arearranged at bottoms of the vertical columns, and guide rails are arranged at upper edges of two side walls of the fermentation cabin. A driving frame with a driving device is mounted at the front endof the erection rods and controlled to move by a control cabinet. An aeration system is arranged at the bottom of the fermentation cabin, an air distribution pipeline is connected with an air blowerand provided with a valve I, and aeration pipes are perpendicular to the air distribution pipeline and connected to aeration heads through aeration branch pipes. A liquid collection tank outside the fermentation cabin is connected with the air distribution pipeline through a liquid collection pipe, and the liquid collection pipe is provided with a valve II. The device has advantages of air exchange acceleration, promotion of organic biological decomposition, prevention of odor escape, reduction of labor cost and the like.

Description

Technical field [0001] The invention relates to the technical field of aerobic composting treatment of organic waste, in particular to an automatic telescopic membrane-covered aerobic composting device. Background technique [0002] With the continuous expansion of agricultural production and livestock and poultry breeding scales, environmental pollution caused by the large-scale discharge of agricultural organic wastes and livestock and poultry manure has become increasingly serious and has attracted widespread attention. In recent years, aerobic composting has been the main treatment method for the treatment of organic wastes such as animal manure, agricultural straws, fruit and vegetable wastes. Under the continuous metabolism of the microbial community, high-temperature aerobic fermentation will mineralize and rot the organic matter in the waste. The qualitative and harmless fertilizer becomes a decomposed fertilizer, with simple process and convenient operation. Trough comp...

Problems solved by technology

Trough composting is a composting process that is widely used in the treatment of livestock and poultry manure in China. However, the commonly used trough composting process generally requires the construction of a special fermentation workshop and the installation of large-scale fermentation and throwing equipment, which occupies a large area and has high construction costs. , and blowing aeration and mechanical turning over will cause a large amount of odorous gases such as ammonia and hydrogen sulfide to be released, affecting the surrounding environment
