Description

Technical Field

[0001] The utility model relates to the technical field of livestock and poultry breeding, in particular to a ventilation device for livestock and poultry houses. Background Art

[0002] Livestock and poultry are typically raised in livestock houses, which provide shelter and protection from the elements. In winter, due to the cold weather, windows in livestock houses are rarely opened, which can lead to the accumulation of carbon dioxide and other harmful gases inside. This can lead to insufficient oxygen supply for the livestock and endanger their survival. Therefore, regular ventilation is necessary to bring in fresh air and expel contaminated air.

[0003] Because livestock and poultry produce odors (such as feces) during the breeding process, the odor is even heavier in the nearly closed environment in winter. If the air in the livestock and poultry house is directly extracted and discharged into the air, it will cause environmental pollution. Utility Model Content

DETAILED DESCRIPTION

[0022] Example 1

[0023] A ventilation device for livestock and poultry houses, such as Figure 1 and Figure 3 As shown, it includes an air intake box 1 and an air bleed box 2; wherein, a plurality of air intake ports and a first negative pressure fan 4 are provided on one side of the air intake box 1, an activated carbon component is provided in the air intake box 1, a filter component is provided between the activated carbon component and the air intake port, an air outlet pipe 19 is provided on the side wall of the air intake box 1, and the air outlet pipe 19 is provided between the activated carbon component and the side wall away from the air intake port; the air inlet end of the first negative pressure fan 4 is respectively connected to the plurality of air intake ports through the first air inlet pipe 5. Further, the filter component includes two layers of filter screens 6 vertically and fixedly arranged in the air intake box 1, and multiple layers of first filter cotton 7 (existing technology) arranged in the two layers of filter screens 6. Further, as Figure 1 and Figure 2 As shown, the activated carbon assembly includes a filter box 9 and granular activated carbon arranged in the filter box 9; the side wall of the filter box 9 and the filter screen 6 are both provided with a plurality of filter holes (existing technology, not shown in the figure), the aperture of the filter hole is smaller than the size of the granular activated carbon and larger than the aperture of the filter cotton. Figure 1 As shown, the outlet end of the first negative pressure blower 4 is provided with a first outlet pipe 13, the outlet end of the first outlet pipe 13 passes through the side wall of the air intake box 1 and is provided with a second outlet pipe 14 having the same length direction as the length direction of the filter box 9. The second outlet pipe 14 is provided with multiple exhaust ports (existing technology, not shown in the figure) on one side close to the activated carbon component, so that the gas sucked into the air intake box 1 is evenly distributed into the filter component, thereby improving the filtration balance and filtration effect. Further, as Figure 3 As shown, the interior of the air bleed box 2 is provided with a second filter cotton 15 (existing technology), the side wall of the air bleed box 2 is provided with a second negative pressure fan 16, and the air inlet end of the second negative pressure fan 16 is connected to the second air inlet pipe 17; the side wall of the air bleed box 2 is provided with multiple air outlets 18.

[0024] Working Principle: The air intake box 1 and the air bleed box 2 are separately installed on the inner wall of the livestock house. During installation, a certain distance must be maintained between the two to minimize the extent to which the air introduced into the livestock house is re-inhaled into the air intake box 1. This effectively ensures that the air inhaled into the air intake box 1 is the air inside the livestock house, thus effectively achieving the purpose of ventilation. Specifically, during installation, the outlet end of the air outlet pipe 19 is allowed to penetrate the wall of the livestock house and extend to the outside air, and the air inlet end of the second air inlet pipe 17 is allowed to penetrate the wall of the livestock house and extend to the outside air. When ventilation is needed, turn on the first negative pressure fan 4 and the second negative pressure fan 16. Under the action of the first negative pressure fan 4, the air in the livestock and poultry house enters the second air outlet 14 along the first air inlet pipe 5, the first negative pressure fan 4, and the first air outlet pipe 13 in sequence, and then is discharged to the filter assembly along the multiple exhaust ports on the side wall of the second air outlet 14, and enters the filter cotton through the filter mesh 6 close to the air intake side. The filter cotton absorbs dust in the air of the livestock and poultry house, and then is discharged into the filter box 9 along the filter mesh 6 away from the air intake side. After the odor is adsorbed by the activated carbon, it is discharged to the external environment along the outlet pipe 19.

[0025] Under the action of the second negative pressure fan 16, the air in the external environment enters the air bleed box 2 along the second air inlet pipe 17 and the second negative pressure fan 16 in sequence, and after the fine impurities in the air are filtered by the second filter cotton 15, it is discharged into the livestock and poultry house through multiple air outlets 18.

[0026] By setting up the synergistic effect of the above-mentioned devices, dust and odor in the livestock and poultry house can be effectively removed, thereby effectively reducing the degree of pollution of the air in the livestock and poultry house to the external environment; through the synergistic effect of the air intake box 1 and the air bleed box 2, the purpose of ventilation can be fully achieved.

[0027] Example 2

[0028] In order to facilitate the maintenance, placement or replacement of various components in the suction box 1, based on Example 1, Figure 1 As shown, a top cover 8 is provided at the top of the air intake box 1, and the top cover 8 is hinged to the air intake box 1, and the opening and closing ends of the top cover 8 and the air intake box 1 can be fixed by a lock (existing technology). When the top cover 8 is closed, it contacts the top of the first filter cotton 7 and the top of the filter box 9 at the same time, so as to prevent the air in the livestock house from being filtered by the first filter cotton 7 or adsorbed by the filter box 9, and then directly passing through the gap between the top cover 8 and the top of the first filter cotton 7 and the top of the filter box 9 to exit the air pipe, causing environmental pollution. Furthermore, in order to improve the smoothness of taking and placing the filter box 9, the two sides of the filter box 9 are slidably connected to the inner wall of the air intake box 1. Further, as Figure 1 and Figure 2As shown, sliders 11 are provided on both sides of the filter box 9 and the air suction box 1 where they are slidably connected, and vertical slide grooves 12 that slide with the sliders 11 are provided on the inner wall of the filter box 9 .

[0029] Working principle: When the first filter cotton 7 needs to be replaced, open the top cover 8, and then replace the first filter cotton 7; when the activated carbon needs to be replaced, open the top cover 8, and then drag the filter box 9 upward. During this process, the slider 11 slides up in the vertical slide groove 12 until it slides out of the vertical slide groove 12, so that the filter box 9 can be taken out of the air intake box 1, which makes it easier to replace the activated carbon.
