Multi-tank type rotating digging turnover mixing apparatus

Abstract

The invention is a multi-tank rotary digging turn-mixing device, mainly including a turn-mixing machine, provided with a group of equal compost fermentation tanks, the end surfaces of the fermentation tanks are provided with a parallel laid railway for a working tank, and the turn-mixing machine is installed on the railway through the bottom idler wheels and cooperates with the railway in rolling mode. There is a rotating frame on one side of the fermentation tanks in the direction of the railway, where the rotating frame mainly includes a carriage and wheels, and the wheel are installed on a round rail at the end part of the railway, and the carriage is provided with two short rails laid at equal space between the railway, the horizontal height of the two short rails is consistent with that of the railway, a reduction electric machine of the rotating frame is connected with a wheel shaft fixed with the wheels through a chain and a chain wheel set. The organic combination of the rotary digging turn-mixing machine with the rotating frame implements the purpose of one machine used by many tanks, and it has the characters of turn-mixing uniformity and high turn-mixing efficiency, fast temperature increase of material fermentation, stable quality of compost maturity, etc.

Description

technical field [0001] The invention relates to a turning and mixing device, in particular to a multi-groove rotary dredging and mixing device. Background technique [0002] Since the 1950s, intensive livestock and poultry farming in developed countries began to develop. On the one hand, this mode of production has greatly improved the level of animal husbandry production, and on the other hand, it has also brought enormous pressure to environmental protection. Livestock and poultry farms produce a large amount of pollution sources such as feces, sewage, and odor every day, causing serious environmental pollution. Many developed countries such as Japan, the United States, Germany, Norway, etc. have stipulated that each scale farm must have storage, treatment and utilization facilities for feces and sewage when building a farm, and sewage shall not be discharged into rivers without permission, and feces shall not be harmless. Treatment shall not be applied to cultivated lan...

AI Technical Summary

Problems solved by technology

Most of Germany, Japan and South Korea use mechanical mixing and inoculation of fermented bacteria for aerobic high-temperature fermentation to treat livestock and poultry manure. The above-mentioned process has a better treatment effect, but the mixing machines used in foreign production are expensive

Domestically, in the past, the drying and reducing method was mainly used to process livestock and poultry manure to produce organic fertilizer. The treatment process requires large capital investment and high energy consumption. The livestock and poultry manure is not fully decomposed, and it is easy to cause crop "burning" after field application, which restricts the organic fertilizer industry. Therefore, the vast majority of farms still return fresh manure to the field directly

At present, some domestic units have developed some composting and mixing equipment for the production of organic fertilizers by the composting process of livestock and poultry manure. Low efficiency, limited production capacity
