Description

Clear excrement device of pig house in scale pig farm

Technical Field

The invention relates to the technical field of animal breeding, in particular to a pigsty manure cleaning device for a large-scale pig farm.

Background

In recent years, the epidemic situation of African swine fever has had a great impact on the global pig industry. In order to ensure the vegetable baskets of urban and rural residents, large-scale and even ultra-large-scale pig farms are firmly constructed in various places so as to ensure the recovery of the productivity of live pigs. The environmental protection problem in the live pig breeding process is always the topic which cannot be avoided by the evaluation of the environmental impact of a pig farm. In the present view, different manure cleaning processes determine the degree of investment for environmental protection to a great extent. Therefore, the research and development of a simple and practical excrement cleaning device with small investment is of great importance to the solution of the environmental protection problem of the large-scale pig farm.

At present, mechanical dung cleaning (flat scraping and micro scraping), water-soaked dung (urine-soaked dung) and water-washed dung are mainly used as dung cleaning processes of large-scale pig farms, but the three dung cleaning processes have defects. Where mechanical dung scraping is capital intensive and relatively fragile, but relatively water efficient. However, the mechanical dung scraping process disturbs dung in the dung scraping process, so that the odor concentration in the pigsty is increased, the air quality in the pigsty is poor, and the growth of pigs is influenced, so that ventilation and deodorization equipment must be matched in the process of using the technology. The water soaking manure or the improved water soaking manure process (urine soaking manure) has the advantages of low construction cost, low management cost and the like, but the process has a great defect that ammonia gas in a pigsty is heavy, and particularly the ammonia gas is obvious in winter and spring seasons. The process is relatively large in terms of water usage compared to mechanical manure scraping. The process of flushing excrement by water is not advocated in the newly-built large-scale pig farm at present, mainly because the water consumption is larger, the air humidity of the pig house is higher, the increase of pig diseases is easily caused, and the cost of rear-end sewage treatment is increased. The water flushing manure process has the largest water consumption in the three manure cleaning processes.

Therefore, the development of a feces cleaning device with less water or no water, low investment and less odor generation to meet the requirement of large-scale or even ultra-large-scale pig farms is urgent.
