Description

Round building pig house with nested air outlet and air inlet channels and method for raising pigs

technical field

The invention relates to the field of pig breeding, in particular to an environment-friendly pig house.

Background technique

Most of the pig houses in our country are single-layer with large spacing and occupy a lot of land. The structure of the pig house is not good, and the functions of wind resistance and snow resistance are poor. It cannot be airtightly sterilized by gas, and the disinfection is not complete. Only equipped with water curtain cooling facilities, unable to maintain constant temperature and humidity in all seasons, automatic ventilation, and high concentration of harmful gases in pig houses in winter. Pig manure cannot be harmlessly fermented into organic fertilizer on the spot after it is dried, and it is not easy to meet the discharge standard after pig urine flushing water is biogas fermented. The environmental protection investment is large and the operating cost is high. There is no purification treatment for the breeding waste gas, the pig house and its surroundings have a strong odor, there are many mosquitoes and flies, and the environment is not good. Feeding with dry feed, although drinking fountains are installed, the amount of drinking water for pigs is insufficient, which affects health. Due to the poor environment and improper feeding methods, the pigs are in a semi-stressed state and are prone to disease. Therefore, farmers add a large amount of antibiotics to the feed and drinking water. The drug residues in pork cannot meet the standards, and food safety has a long way to go. Although there are multiple pig houses and various new feeding patterns to occur at present, the above problems cannot be solved systematically.

The wall of the first channel 102 is the inner wall of the second channel 103, the outer wall of the second channel 103 is the inner wall of the pigsty 101, and the second channel 103 has a hole to communicate with the nursery piglet 101; The ceiling of 101 is equipped with air intake fan 108.

The air path is: the air intake device 105 introduces fresh air from the outside into the first passage 102, then passes through the second passage 103 by the pipeline through the first passage 102, and is sent into the pigsty 101 by the air intake fan, along the pigsty. The ceiling of the pigsty 101 flows through the outer wall of the pigsty 101 and moves to the floor of the pigsty 101 to become dirty air. The dirty air flows upwards through the second channel 102 and is discharged after being purified by the air purification device 107, thus completing the air purification process. the whole process of the cycle. Excreta in the pigsty 101 enters the second channel from the hole and falls into the pig excrement and urine collection device 106 .

Further, the air outlet of the air inlet fan 108 is provided with a deflector, so that the air inlet fan 108 forms a uniform fan-shaped air outlet surface.

The floor of each pigsty 101 is provided with three steps 1011, 1012, 1013 descending successively from the outside side away from the second passage 103 to the inside of the second passage 104; wherein the outermost step 1011 is a sleeping area for pigs; the middle The step 1012 is the pig eating area; the innermost step 1013 is the pig excretion area; the outermost step 1011 area accounts for 50%-60% of the pigsty 101 area, and the innermost step 1013 area accounts for 10% of the pigsty 101 area. %-15%. The advantage of setting like this is that pig can comprehend its intention, make it can go to the outermost step 1011 to sleep spontaneously, and the innermost step 1013 is excreted. In this way, each functional partition will not affect each other, and it also ensures that feces and urine will not pollute the other two steps.

The floor of each step 1011, 1012, 1013 is inclined from high to low from the outside to the inside; the height of the steps is 5-15cm, and the floor gradient of the steps is 1%-3%. The innermost step 1013 communicates with the second passage 103 , so that the excrement in the excretion area falls into the pig excrement and urine collection device 106 through the passage.

The air treatment channel 104 has a length of 30-40 meters and a cross-sectional area of 6-8 square meters. It has an air supply device, a sensor, a spray cooling device, a refrigeration device and a heating device; the sensor detects the temperature and humidity of the air sent into the air treatment channel by the air supply device; when the air humidity is high and the temperature is low, the heating device starts to The air is heated and heated; when the air temperature is high and the humidity is low, the spray cooling device is activated to cool and humidify the air; when the air temperature is high and the humidity is high, the refrigeration device is activated to cool and dehumidify the air.

There are three groups of spray cooling devices. According to the level of air temperature and humidity, one group, two groups or three groups of the three groups of spray cooling devices are turned on.

Air temperature and humidity are adjusted according to the characteristics of piglets. Piglets weighing 9-30kg use suckling pig nursery feed. The feed is mixed with water at a ratio of 1:3 on the first floor, and after fermentation, it is transported to each trough by a gear pump for automatic feeding. The pig manure is manually swept into the circular channel, and the pig urine flows in automatically. If it is difficult to clean the piglets with diarrhea, it can be cleaned after sprinkled with a desiccant. The desiccant does not affect the fermentation of pig manure. The lighting window can adjust the light intensity according to the characteristics of piglets. After the nursery is completed, all the piglets in the nursery house are transferred out. After being transferred out, each floor is sealed for ozone disinfection after cleaning.

The floor separation structure of the middle pig house building and the large pig house building is the same as that of the nursery piglet sty 101, and will not be repeated here.

Nursing piglets are reared in captivity for 45 days in the Nursing Piglet Building 100, and after making their body weight reach 30kg, they enter the pigsty of the Middle Pig Shed Building 200 through the passage and the auxiliary setting building, and each pig pen in the Middle Pig Shed Building 200 30 medium pigs were reared in the middle cage, and after 45 days in the same cage, their body weight reached 75 kg. After that, enter the pigsty of the big pig house building 300,400 through the passage and the auxiliary setting building. Since there are two big pig house buildings, there are only pigsty in each big pig house building 300,400. There are 15 big pigs, which ensure the activity space of the big pigs. After raising in captivity for 45 days, make its body weight reach 125kg and go out of the circle as finished pigs. After the finished pigs are sold, each floor is cleaned and sealed for ozone disinfection.
