[0002] In modern livestock farming, environmental control in the brooding room is crucial for the healthy growth of chicks. Ventilation is a key measure to maintain fresh air in the brooding room, reduce the concentration of harmful gases and humidity, and prevent the spread of diseases. As a commonly used ventilation method, the negative pressure ventilation system creates negative pressure in the brooding room by drawing air out of the fan, which promotes the entry of fresh outdoor air into the room through the air inlet, thereby effectively improving indoor air quality.

[0003] Existing negative pressure ventilation and dust removal equipment typically filters dust, feather debris, and other impurities through filters during the air exchange between the brooding room and the outside. However, as time goes on, the dust accumulation on the filters becomes thicker and thicker, leading to a significant increase in ventilation resistance. This requires regular manual cleaning or cleaning with an additional power source, which increases the operating cost of the equipment.

[0004] Therefore, it is necessary to design a negative pressure ventilation and dust removal device for brooding rooms that can automatically scrape off dust from the filter screen during ventilation, without the need for an additional power source, continuously maintain air quality, and improve ventilation efficiency.

Detailed Implementation

[0021] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0022] A negative pressure ventilation and dust removal device for brooding rooms, such as Figures 1-3 As shown, it includes a ventilation duct 1, a first fan 2, a second fan 3, a filter plate 4, a filter screen 5, a placement frame 6, a filter 7, an adjustment component, and a cleaning component. The first fan 2 is rotatably connected to the lower part of the ventilation duct 1, and the second fan 3 is rotatably connected to the upper part of the ventilation duct 1. The filter plate 4 is slidably snapped onto the upper part of the ventilation duct 1. The left side of the filter plate 4 has a gripping groove for easy gripping. The filter plate 4 has two fan-shaped grooves for ventilation. The filter plate 4 is located above the second fan 3. The filter screen 5 is slidably snapped onto the lower part of the ventilation duct 1. The filter screen 5 is located below the first fan 2. The placement frame 6 is connected to the inner side of the middle part of the ventilation duct 1. Three filters 7 are snapped into the placement frame 6. The filter plate 4 is equipped with an adjustment component. The lower part of the ventilation duct 1 is equipped with a cleaning component.

[0023] like Figure 4 As shown, the adjustment assembly includes a support frame 8, a rotating plate 9, a motor 10, and a first pulley 11. The support frame 8 is connected to the upper inner side of the ventilation pipe 1, the motor 10 is connected to the rear of the support frame 8, the rotating plate 9 is rotatably connected to the support frame 8, the first pulley 11 is connected to the output shaft of the motor 10, the first pulley 11 is also connected to the lower middle part of the rotating plate 9, and a first flat belt is wound around the first pulleys 11.

[0024] like Figure 1 , Figure 2 and Figure 5As shown, it also includes a cleaning assembly, which includes a bevel gear 12, a rotating shaft 13, a second pulley 14, a reciprocating screw 15, a scraper 16, a support frame 17, and a collection frame 18. The lower right part of the ventilation pipe 1 is rotatably connected to the rotating shaft 13. The lower part of the first fan 2 is connected to the bevel gear 12, and the left part of the rotating shaft 13 is also connected to the bevel gear 12. The bevel gears 12 mesh with each other. The lower front part of the ventilation pipe 1 is rotatably connected to the reciprocating screw 15. The right part of the rotating shaft 13 is connected to the second pulley 14, and the right side of the reciprocating screw 15 is also connected to the second pulley 14. A second flat belt is wound between the second pulleys 14. The reciprocating screw 15 is threadedly connected to the scraper 16, which is slidably connected to the ventilation pipe 1 and contacts the filter screen 5. The lower part of the ventilation pipe 1 is externally connected to the support frame 17, and the collection frame 18 is placed on the support frame 17.

[0025] When using this device, first install the ventilation duct 1 at the ventilation point of the brooding room, then turn on the second fan 3 to allow outdoor air to enter the ventilation duct 1 through the filter plate 4. The air then passes through the filter 7 on the placement frame 6 to filter and purify impurities, allowing fresh air to be discharged into the brooding room through the filter screen 5. When ventilation and dust removal are needed in the brooding room, the first fan 2 can be turned on to allow dust-laden air to enter the ventilation duct 1 through the filter screen 5. The filter screen 5 and filter 7 then filter and purify the air, allowing it to be discharged through the filter plate 4. The rotation of the first fan 2 drives the bevel gear 12 to rotate. The meshing motion of the bevel gears 12 drives the rotating shaft 13 to rotate, causing the second pulley 14 to rotate, which in turn drives the second flat belt to rotate, causing the reciprocating screw 15 to rotate. This causes the scraper 16 to move left and right under the action of the screw thread, thus filtering the air. Dust on the filter screen 5 is scraped off and falls onto the collection frame 18, thus automatically scraping off dust on the filter screen 5 during ventilation. No additional power source is needed, continuously maintaining air quality and improving ventilation efficiency. When it is necessary to adjust the ventilation volume, the motor 10 can be started to drive the first pulley 11 to rotate, causing the first flat belt to rotate, which in turn drives the rotating plate 9 to rotate. By controlling the rotation angle of the rotating plate 9, the ventilation volume can be controlled, thereby regulating and controlling the ventilation volume to avoid sudden temperature drops due to excessive ventilation or overheating caused by insufficient ventilation. When it is necessary to disassemble and clean the filter plate 4, filter screen 5, and filter 7, the filter plate 4 and filter screen 5 can be moved to the left and removed, and the filter 7 can be moved from the placement frame 6 and removed for cleaning. This makes it easy to remove the filter plate 4, filter screen 5, and filter 7 for cleaning or replacement.
