Description

Simple environmental protection pig house

technical field

The utility model relates to a simple environment-friendly pig house.

Background technique

At present, the existing pig houses mainly adopt the structure of the sewage ditch in the middle of the high bed above, or the sewage ditch in the middle of the slatted floor above. For this type of pig house, the sewage ditch has not been thoroughly cleaned and disinfected almost since the pig house was built and put into operation. The cleaning of the sewage ditch is carried out only by regular flushing every day. Since flushing water cannot thoroughly clean the excrement and urine in the sewage ditch, and the disinfectant cannot be evenly sprayed in the sewage ditch, the sewage ditch forms one of the protection areas for the source of infectious diseases; the second large amount of flushing water is mixed with feces. , the volume is huge, and the treatment is difficult. At present, the sewage is mainly deposited in the sewage treatment tank, and then the pig manure residue and the liquid sewage are separated by a solid-liquid separator. However, the investment in the treatment equipment is large, the area of the sewage treatment tank is large, and the investment and operation costs are high. It is difficult to maintain long-term normal operation; third, this type of pig house consumes a lot of water (a large pig farm with 600 sows that sell commercial pigs annually consumes 100-150 tons of water per day, and the annual sewage discharge can reach 70,000 tons). Fourth, the chemical oxygen demand and biochemical oxygen demand of the sewage discharged from this type of pig house are relatively high, and the daily maintenance cost of sewage treatment is high. Obviously, this technical route is not suitable for the current water-saving and energy-saving requirements, especially for raising pigs in the central and northern regions of my country.

Another kind of pig house is currently a new type of "pig manure fermentation treatment" technology. In this method, short-cut straw, wheat straw, sawdust and other straws are mixed with pig manure and a variety of specific fermentation bacteria, and spread on the ground with a litter height of about 60-80cm. Large groups of weaned piglets or pigs are raised on the ground , while adding 0.1% of specific strains to pig feed or litter. The pig's excrement and urine are naturally decomposed by fermentation bacteria on the filler, and there is no odor. The filler is fermented to generate heat, and the ground is warm and soft to protect the trotters. In the future, the litter will be added continuously, and it will be cleaned once every 1 to 2 years. The resulting filler is also a good fertilizer. The disadvantage is that in summer, due to the high temperature of the litter, pigs don’t like to sleep on the litter, so they need to choose another place to sleep. At the same time, the temperature of the pig house is high, which is not conducive to the rapid growth of pigs, and it is difficult to disinfect. Serious diseases are difficult to prevent and treat.

Utility model content

The purpose of the utility model is mainly to solve the above-mentioned problems existing in the existing pig house, and to provide a simple and environmentally friendly pig house that separates the feces and urine in the pig house, reduces the amount of flushing water, and improves the air quality in the pig house.

The utility model is achieved in that:

A simple environment-friendly pig house, characterized in that: there is a working channel in the middle of the pig house, the pig pens are arranged symmetrically along both sides of the working channel in the pig house, the ground of the pig house in the pig house is slope type, and the side near the working channel The ground level is higher than the ground near the outer wall of the pig house.

A further solution is: the side of the ground of the pig house close to the working channel in the middle of the pig house is 10-20 cm higher than the ground near the outer wall of the pig house.

A further solution is: the side of the pig house close to the outer wall is provided with a sewage outlet, and a pig manure isolation board with a plurality of small holes is fixedly installed outside the sewage outlet.

A further solution is: the sewage outlet is arranged on the outer wall of the pig house close to the ground, with a length of 30-40cm and a height of 20-30cm.

A further scheme is that the length of the pig manure separation plate is 40-50cm, the height is 30-40cm, the diameter of the small holes on the separation plate is 1.5-2cm, and the distance between the small holes is 3-6cm.

A further solution is: the sewage outlet is externally connected with a sewage ditch, and the sewage ditch is connected with a biogas digester or a liquid storage tank.

The floor of the pig house is a cement floor that does not flow into the sewage ditch. The cement floor near the middle of the pig house is 10-20cm higher than the ground near the outer wall of the pig house. At the same time, dig a 30-40cm long and 20-30cm high sewage outlet near the ground on the outer wall of the pig house, and install a pig manure isolation board at the sewage outlet outside the wall. There are many small holes on the board to prevent pig manure from flowing out and facilitate urine liquid and a small amount of rinse water flow out. In the dry-wet separation, the dry manure is picked up manually, and the urine automatically flows into the sewage ditch, which can greatly reduce the amount of flushing water. Compared with the pig house in the middle sewage ditch, the water consumption can be reduced by about 2/3 of the flushing water. Dry manure can produce high-quality organic fertilizer. Moreover, considerable income can be obtained, and the biochemical value of the discharged sewage is low. When connected to a biogas digester, biogas can be produced to solve the energy consumption of domestic energy and the heating of pig houses. Biogas manure is a high-quality organic fertilizer, which can provide high-quality fertilizer for crops and reduce waste. input of fertilizers. At the same time, the sewage ditch of the pig house is set outside the pig house, which significantly improves the air quality in the pig house, reduces the amount of pollutants in the pig house, improves the working environment of people and the breeding environment of pigs, and realizes the separation of rain and sewage , to solve the problem of the same flow of rain and sewage in the past. Build a sewage ditch close to the wall, which is directly connected to the biogas digester or liquid storage tank, and above the sewage ditch, use a rain barrier, or install a rain receiving device under the eaves of the pig house. The pig house has low construction or reconstruction cost, low operating cost and simple operation.

Description of drawings

Figure 1 is a schematic diagram of the structure of a simple environment-friendly pig house.

Detailed ways

As shown in accompanying drawing 1, working channel 8 is in the middle part of pigsty 1, and the left and right sides of pigsty are arranged symmetrically. The height of the ground 2 of the pig house is slope type, and the ground close to the working channel is about 10-20cm higher than the ground close to the outer wall. The effect of this setting is to allow pig urine to flow to the sewage outlet by itself. After the pig urine passes through the sewage outlet, it needs to pass through the pig manure isolation plate 4 to isolate the pig manure and flow into the sewage ditch 3. There are multiple small holes on the isolation plate 4. The diameter of the small holes is 1.5-2cm, and the distance between the small holes is not greater than 3-2 cm. 6cm, the length of the isolation plate is 40-50cm, and the height is 30-40cm. At the fixed and sewage outlet, the extension of the sewage ditch 3 should be higher than the ground. The material of the isolation plate 4 is one of PE, PP and PVC.

The purpose of this setting is to realize the dry-wet separation of pig manure and pig urine, so that the breeder can pick up the pig manure conveniently. At the same time, because the ground 2 of the pigsty is less polluted, after the pig manure is picked up, it only needs to be washed with a small amount of flushing water to clean the pigsty. The purpose of cleaning the pigsty can be achieved. In addition, the picked up pig manure is transported out of the pig house and stored in the manure storage tank, which can be used as high-quality organic fertilizer, which is convenient for processing and utilization.

In addition, the separated pig urine and a small amount of flushing water can flow into the biogas digester 7 or liquid storage tank 6 through the sewage ditch 3 for anaerobic fermentation or subsequent treatment.

The function of such setting is to make pig urine and a small amount of flushing water be processed by the biogas tank 7, reduce the subsequent processing expenses, and realize a virtuous cycle. If there is no biogas tank 7, a liquid storage tank 6 can be built for processing.

A rain barrier 5 is installed on the sewage ditch 3. The purpose of this setting is to prevent rainwater from flowing into the sewage ditch, increase the volume of sewage discharge, increase the chemical oxygen demand and biochemical oxygen demand of the discharged sewage and the subsequent treatment. At the same time, the device can Reduce water waste. Also can install the eaves rain receiving device 9 if breeding plant economic condition allows in addition, and need not install the rain-proof plate 5.
