Description

Technical Field

[0001] The utility model relates to the technical field of pig farming, in particular to a ventilation system suitable for pig sheds. Background Art

[0002] At present, my country's animal husbandry industry is developing rapidly in scale and concentration. The ventilation system of pig houses in the pig farming industry has become one of the important factors to measure the current pig breeding level, which directly affects the healthy growth of pigs. The appropriate ventilation system design can meet the growth of pigs, improve the air quality of pig houses, and adjust the temperature and humidity of pig houses. At present, the industry mainly focuses on ventilation mode and ventilation uniformity. Different ventilation modes directly lead to differences in the growth of pigs. In order to ensure the quality of pig farming, it is necessary to ventilate the pig houses well.

[0003] When designing a pig house ventilation system, it is necessary to consider the wind speed, ventilation volume, temperature and humidity, and stress status of pigs in the pig house. In the actual pig house construction and application process, there will be problems such as poor airtightness of the building structure, low surface wind speed within the pigs' activity space, and uneven temperature distribution. This leads to large differences in the fresh air that pigs breathe, and they cannot effectively breathe fresh air. In addition, harmful gases cannot be exchanged and discharged outside the house in time, which brings about biosafety problems for pigs. Therefore, the design of the pig house ventilation mode can determine whether the pigs can breathe fresh air, as well as the pigs' surface temperature, which in turn affects the growth of the pigs.

[0004] However, at present, most pig farming adopts a tunnel ventilation mode, that is, air enters from one end of the pig house, and a fan is installed at the other end to draw the air out of the house. Under this ventilation mode, if the outside air quality is poor or there are pathogens, it will cause the pigs to become infected and fall ill; and the air always flows from front to back, which will cause the pigs in the back pen to breathe poor air quality, affecting their growth; the surface air volume of the pigs in the back pen is drawn away by the fan, resulting in ineffective ventilation. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a ventilation system suitable for pig houses in view of the above shortcomings. The utility model has a reasonable structure, can ensure that fresh air blows evenly to each pig, ensures that the pig's body temperature is comfortable, and greatly reduces the ventilation dead zone area.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A ventilation system suitable for a piggery, comprising a piggery body, wherein a suspended ceiling is arranged inside the piggery body, wherein the suspended ceiling divides the internal space of the piggery body into an upper ventilation area and a lower cultivation area, wherein a plurality of nasal tubes are arranged on the suspended ceiling, wherein the nasal tubes connect the ventilation area and the cultivation area;

[0008] On both sides of the pig house body, a first wall surface and a second wall surface are sequentially arranged from outside to inside. A water curtain is arranged on the first wall surface, and a number of positive pressure fans are arranged on the second wall surface.

[0010] Louver windows are arranged on the front and back sides of the pig house body.

[0011] Furthermore, a filtration room is arranged outside the pig house body. The outside of the filtration room is communicated with the water curtain. A三防网 (three-proof net) is arranged outside the filtration room, and an air filtration component is arranged inside the filtration room.

[0012] Furthermore, the air filtration component is arranged in a "ji" shape in the filtration room.

[0013] Furthermore, the wind blocking component includes a height adjustment frame and a wind blocking plate. The height adjustment frame is vertically arranged at the inner top of the pig house body. The wind blocking plate is arranged at the bottom end of the height adjustment frame. The height adjustment frame is used to adjust the height of the wind blocking plate, and the relative angle between the wind blocking plate and the height adjustment frame is adjustable.

[0014] Furthermore, the distance between the wind blocking plate and the ceiling is gradually reduced from outside to inside.

[0015] Furthermore, the included angle between the wind blocking plate and the adjacent second wall surface is 60°.

[0016] Furthermore, a vertical first outlet and an inclined second outlet are arranged at the bottom end of the nasal tube.

[0017] Furthermore, a wind valve is arranged on the first outlet.

[0018] Furthermore, an anti-backflow rolling curtain is arranged on the louver window.

[0020] The present utility model adopts a two-way full positive pressure ventilation mode, which can blow the air on both sides of the pig house into the pig house interior. The external air is filtered and dust-removed through the air filtration component to ensure that the fresh air is clean and sterile. Then, it is cooled by the water curtain, and finally blown into the ventilation area by the positive pressure fans. The wind blocking component can ensure the uniformity of the air entering the nasal tube in the ventilation area. The nasal tube is connected to the breeding unit in the pig house, so that the fresh air can accurately reach each pig. The air in the pig house is then discharged to the outside of the house through the louver windows;

[0021] The utility model arranges a plurality of wind-blocking components in the ventilation area, and the wind-blocking components can block part of the fresh air blown out from the positive pressure fan, and guide the fresh air to the nose tube below. The unblocked fresh air will continue to blow to the middle of the ventilation area until it contacts the next wind-blocking plate, and the distance between the wind-blocking plate and the nose tube gradually decreases from the positive pressure fan to the middle of the ventilation area to adapt to the gradually decreasing wind speed, so as to ensure that the wind speed and air volume output from each nose tube are uniform;

[0022] The output end of the nasal tube adopts a "y"-shaped design, which can blow fresh air to the head area and body surface area of ​​the pig, so as to distribute the fresh air from the head to the tail of the pig, and the air valve can change the air outlet from the first outlet to adjust the air outlet ratio of the first outlet and the second outlet to achieve the best air outlet effect.

[0039] Preferably, the distance between the wind blocking plate 62 and the suspended ceiling 2 gradually decreases from outside to inside.

[0040] Preferably, the angle between the wind blocking plate 62 and the adjacent second wall 12 is 60°.

[0041] like Figure 4 As shown, as an embodiment, a vertical first outlet 31 and an inclined second outlet 32 ​​are provided at the bottom end of the nasal tube 3 , and a wind valve 33 is provided on the first outlet 31 .

[0042] Preferably, the shutter 8 is provided with a backwind prevention roller blind.

[0043] Embodiment 1:

[0044] like Figure 1 and Figure 2 As shown, filter rooms 7 are arranged on both sides of the pig house body 1, and a three-proof net 71 is arranged outside the filter room 7. An air filter assembly 72 arranged in a "J" shape is arranged in the filter room 71. The air filter assembly 72 includes a primary filter and a high-efficiency filter, with a total of four layers;

[0045] The first wall 11 of the pig house body 1 is connected to the filter room 7. A water curtain 4 is arranged on the first wall 11. A plurality of positive pressure fans 5 are arranged on the upper part of the second wall 12. Eight positive pressure fans 5 are arranged on the second wall 12 on one side, and a total of sixteen positive pressure fans 5 are arranged on both sides. The output wind pressure of the positive pressure fan 5 is 200Pa and the air volume is 28000m 3 / h;

[0046] The wind blocking assembly 6 is composed of a height adjustment frame 61 and a wind blocking plate 62. A mounting plate is provided on the top of the height adjustment frame 61, and the mounting plate is connected and fixed to the steel structure in the house. Figure 3 As shown, the height adjustment frame 61 is formed by two round tubes of different diameters, the large tube has a hole, the upper part of which is welded to the mounting plate, the small tube with a spring buckle is inserted into the large tube to adjust the overall length, and the lower end is connected to the wind blocking plate 62, wherein the wind blocking plate 62 and the lower end of the small tube are designed to be angle-adjustable to control the wind blocking size;

[0047] The nose tube 3 is designed with a "Y"-shaped outlet, and a wind valve 33 is provided on the first outlet 31 to control the air volume directly blown to the pig's body surface. By changing the air volume of the first outlet 31, the air volume of the second outlet 32 ​​can also be adjusted. The Y-shaped air outlet can evenly disperse the fresh air in the area from the head to the tail of the pig;

[0048] The shutters 8 are electric shutters. Eight sets of shutters 8 are respectively installed at the front, middle and rear parts of the pig house body 1, and anti-return wind roller curtains are arranged on the shutters 8.

[0049] The air outside the house passes through the three-proof net 71 to the air filter assembly 72, and the fresh air that is about to enter the house is filtered and dusted to ensure that the fresh air is clean and sterile. The fresh air is then cooled by the water curtain 4 to ensure that the air temperature enters the house at a lower temperature, and then blown into the ventilation area 1a under the action of the positive pressure fan 5. At this time, the wind speed just entering the ventilation area 1a (i.e., the upper part of the suspended ceiling 2) is relatively large. Under the action of the front wind blocking plate 62, the fresh air will be blocked and blown downward to the nasal tube 3. The unblocked fresh air continues to blow toward the middle of the ventilation area 1a until it contacts the next wind blocking plate 62, and is blocked and blown downward into the nasal tube 3 below. Since the wind speed at the output end of the positive pressure fan 5 to the middle of the pig house will gradually weaken, and the distance between the wind blocking plate 62 and the nasal tube 3 will continue to decrease, the fresh air will blow to the nasal tube 3 at an increasingly shorter distance, and then blow to the pig's body surface, ensuring the wind speed and air volume of the entire house blowing to the pigs, and finally discharged to the outside of the house through the shutter 8.

[0050] Among them, the multi-level wind resistance plate will reduce the staying and filling of the incoming wind inside the ventilation area 1a, and blow it to the nasal tube at the fastest speed. The multi-level wind resistance will ensure the uniformity of the air blowing for the pigs in the pig house. There will not be a large amount of air blowing on the pigs' body surface in the front, and the air volume will become less and less towards the middle of the pigs. Each pen is equipped with a nasal tube (with a valve to control the air volume) to ensure that fresh air is accurately delivered to each pig. Anti-backwind roller curtains are installed outside the blinds.

[0051] The above is an example of the best implementation of the utility model, and the parts not described in detail are common knowledge of ordinary technicians in this field.
