Film-covered aerobic fermentation special multi-functional high-efficiency turning device

Abstract

The invention relates to a film-covered multifunctional high-efficiency turning device for aerobic fermentation, which includes: a walking device, including a crawler and a crawler power device connected to the crawler; a main body bracket, including two horizontal load-bearing brackets and two longitudinal fixed brackets ;The chain plate conveying device is placed obliquely above the horizontal load-bearing support, and is used to actively grab the materials in the middle and lower layers, and mix the actively grabbed materials and the material taken by the reclaiming device to the chain plate conveying device and fix them backward Transmission at a distance; the reclaiming device is set above the chain conveyor device, which is used to chop the middle and upper layer materials and throw them backwards to the chain conveyor device; the reclaiming support frame includes two reclaiming static supports Rod and two reclaiming hydraulic telescopic rods. The invention can regularly turn the material under the film without removing the film, and at the same time meet the requirements of precise feeding, material translation, precise discharging, and bacterial agent spraying.

Description

technical field [0001] The invention relates to the technical field of organic solid waste disposal and resource utilization, in particular to a film-covered multi-functional and high-efficiency turning device for aerobic fermentation. Background technique [0002] High-temperature aerobic fermentation is currently one of the mainstream methods for large-scale treatment of livestock and poultry manure in my country to realize its resourceful, harmless and reduced utilization. In the process of high-temperature aerobic fermentation, regular turning is an important means to achieve high-quality and efficient fermentation. Regular turning of the pile materials can make the materials fully contact with the air, improve the activity of aerobic microorganisms, and promote the heat production of fermentation. , to speed up the evaporation of water; on the other hand, it can evenly mix the materials at different spatial gradients, and at the same time, it can also restore the porosi...

Problems solved by technology

Usually, this technical mode requires that the stacking of materials should not exceed 1.8 meters, and at the same time cover the material surface with functional membrane materials and maintain the covering state throughout the fermentation cycle to achieve high-quality and efficient fermentation, greenhouse gas and odor gas emission reduction, but this technical mode The lower material cannot be turned directly, and there are problems such as uneven fermentation, serious agglomeration, and low water removal efficiency.

However, due to the limitations of its structural characteristics and application scenarios, the traditional turning device cannot be directly applied to the film-covered aerobic fermentation process without removing the film. If the film is removed first and then the pile is turned, or Turning the pile while removing the film will cause a large amount of emissions of greenhouse gases and odorous gases, and lose the excellent environmental protection advantages of the film-covered aerobic fermentation technology itself
