Feces and water separating device for fresh duck feces

Abstract

The invention provides a feces and water separating device for fresh duck feces. The feces and water separating device comprises a supporting frame, a lifting pump is fixedly arranged at one end of the supporting frame, one end of the lifting pump communicates with a duck shed feces and water pool, the other end of the lifting pump is connected with a feeding device, and a filtering system is arranged on the lower part of the feeding device; the filtering system comprises a main roll shaft and an auxiliary roll shaft, the two roll shafts are coated with a conveying belt, a water absorbing material layer is arranged on the outer part of the conveying belt, and a water discharging pipe is arranged on the lower part of filtering system and communicates with a wastewater collecting pool; a feces scraping plate is arranged on one side of the main roll shaft and connected with a feces guiding plate, the feces scraping plate communicates with a receiving device, the receiving device comprisesa fixed seat and a rotating disc rotatably connected with the top of the fixed seat, a plurality of receiving buckets are placed on the rotating disc, stirrers are arranged in the receiving buckets,and an intermittent rotating structure is further arranged on the rotating disc. The feces and water separating device for the fresh duck feces has the beneficial effects that the design is reasonable, the structure is simple, security and reliability are achieved, the content of water in the fresh duck feces can be reduced, the dewatered duck feces is subjected to treatment of an early stage of fermentation, and subsequent resourceful utilization of the duck feces is facilitated.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry breeding machinery, in particular to a fresh duck manure water separation device. Background technique [0002] Nowadays, with the continuous development of the domestic breeding industry, meat duck farming has gradually entered the era of cage and net breeding. Large-scale and standardized breeding will inevitably bring about the problem of breeding manure. In recent years, with the country's emphasis on environmental protection, breeding enterprises must not It does not face the pressure of environmental protection policies in all aspects of breeding. [0003] Livestock and poultry manure has always been considered as a good raw material for producing biogas. After duck manure is fermented with biogas, it can not only produce cheap and convenient energy—biogas, but also the residue after fermentation is a kind of high-quality organic fertilizer. In addition, poultry Manure is rich...

Problems solved by technology

[0004] Different from other livestock and poultry manure, duck manure has high water content, and the particularity of physical and chemical properties leads to poor separation effect of duck manure dry matter and water by existing methods. Duck manure is mixed with shedding duck feathers and duck down, which makes the separation of manure and water more difficult. difficulty

At the same time, limited by the profitability of the breeding industry, it is difficult for breeding enterprises or farms to invest a lot of money in the construction of duck manure water separation and subsequent treatment facilities

The subsequent treatment of duck manure that has not been fully separated from manure and water is difficult, which not only pollutes the environment, but also wastes resources. It is one of the bottlenecks that plague the duck industry and is not conducive to the healthy and sustainable development of the industry.

[0005] At present, the separation of livestock and poultry manure and manure mainly adopts physical or mechanical separation methods, and dehydration is carried out by means of inclined sieve plate extrusion separator or screw extrusion. High difficulty and other problems, and high energy consumption and high production cost

[0006] At the same time, in the process of making organic fertilizer, it is necessary to add auxiliary materials to the dehydrated duck manure, such as straws of various crops, grass, pine shells, straw, peanut skins, etc., and also add an appropriate amount of starter and stir them , the stirred duck manure is composted and fermented. In this process, the duck manure needs to be manually stirred, which not only consumes a lot of manpower but also has a strong smell, which is unbearable. Therefore, the meat duck breeding industry urgently needs a simple, efficient and low-input fresh duck. Fecal water separation device
