Description

Technical Field

[0001] The utility model relates to the technical field of turkey breeding, and specifically discloses a ventilation device for a chicken house. Background Art

[0002] During the ventilation process of the chicken house used for turkey breeding, the exhaust gas generated in the chicken house is discharged by driving the exhaust fan, and at the same time a negative pressure is formed in the chicken house. Under the action of atmospheric pressure, fresh air from the outside is introduced into the chicken house through the side wind windows, thereby achieving ventilation of the chicken house.

[0003] During the use of existing ventilation devices, the exhaust fan directly discharges the exhaust gas, which makes the heat energy of the exhaust gas unusable. In addition, the introduced fresh air will affect the temperature in the chicken house, causing the temperature to drop or rise rapidly. Therefore, the temperature in the chicken house needs to be readjusted on a large scale, resulting in a waste of resources. Utility Model Content

[0005] Preferably, the heat exchange mechanism includes a first square tube and a second square tube fixedly installed on the outside of the exhaust fan, the top of the first square tube is connected to a first connecting tube fixedly installed on the bottom of the first PVC spring tube, the bottom of the second square tube is connected to a second connecting tube fixedly installed on the top of the third PVC spring tube, and the first square tube and the second square tube are connected to heat exchange tubes arranged in a staggered manner, and fins are arranged on the outside of the heat exchange tubes.

[0006] Preferably, the filtering mechanism includes a fixing frame clamped inside the air inlet pipe. A filter screen is arranged inside the fixing frame, a handle is arranged outside the fixing frame, and a magnet is arranged inside the fixing frame.

[0007] Preferably, the sealing mechanism includes an electric telescopic rod rotatably connected to the outside of the air inlet pipe through a first fixing pin and a sealing plate rotatably connected to the lower part of the air inlet pipe through a second fixing pin. A third fixing pin fixedly sleeved inside the sealing plate is movably sleeved inside the bottom end of the electric telescopic rod.

[0008] Beneficial effects:

[0009] 1. For the ventilation and air exchange device for the chicken coop, driven by the exhaust fan, the waste gas inside the chicken coop can be discharged to the outside. At the same time, the waste gas exchanges heat through contact with the heat exchange pipe. Then, under the action of atmospheric pressure, fresh air from the outside is introduced into the inside of the heat exchange pipe through the air inlet pipe for heat exchange. At this time, the fresh air transported into the chicken coop will not cause the temperature inside the chicken coop to drop or rise rapidly after heat exchange, and the temperature inside the chicken coop only needs to be adjusted within a small range. With this structure, the waste gas can be reused, reducing waste of resources.

[0010] 2. For the ventilation and air exchange device for the chicken coop, by embedding the underground air pipe in the ground, the underground air pipe can exchange heat with the soil. Then, the fresh air entering the inside of the underground air pipe can exchange heat with the underground air pipe, reducing energy loss. And driven by the exhaust fan, the inside of the third connecting pipe can be evacuated, thereby generating negative pressure inside the fresh air supply pipeline, so as to accelerate the speed of fresh air from the outside entering the chicken coop.

Through the coordinated use of the first PVC spring tube 6, the second PVC spring tube 8, the third PVC spring tube 10 and the fourth PVC spring tube 12, the fresh air supply pipelines can be installed and fixed by bolts to facilitate the disassembly and assembly of the fresh air supply pipelines.

[0021] Among them, the heat exchange mechanism 5 includes a first square tube 51 and a second square tube 52 fixedly installed on the outside of the exhaust fan 3. The top of the first square tube 51 is connected to a first connecting tube 53 fixedly installed on the bottom of the first PVC spring tube 6, and the bottom of the second square tube 52 is connected to a second connecting tube 54 fixedly installed on the top of the third PVC spring tube 10. The first square tube 51 and the second square tube 52 are connected by staggered heat exchange tubes 55. Fins 56 are arranged on the outside of the heat exchange tubes 55. The fins 56 can increase the contact area between the heat exchange tubes 55 and the exhaust gas, thereby facilitating heat exchange between the exhaust gas and the heat exchange tubes 55.

[0022] Among them, the filtering mechanism 14 includes a fixing frame 141 clamped inside the air inlet pipe 4. A filter screen 142 is arranged inside the fixing frame 141. The introduced fresh air can be filtered through the filter screen 142, thereby reducing the dust content in the fresh air. A handle 143 is arranged outside the fixing frame 141. The handle 143 facilitates the pushing, pulling, disassembly and assembly of the fixing frame 141 and is convenient for cleaning the filter screen 142. A magnet 144 is arranged inside the fixing frame 141.

The driving of the exhaust fan 3 discharges the waste gas inside the chicken coop 1 to the outside of the chicken coop 1. During this process, heat exchange is carried out by the contact between the waste gas and the heat exchange pipe 55. After the waste gas inside the chicken coop 1 is discharged to the outside, a negative pressure can be formed inside the chicken coop 1. The outside fresh air is introduced into the inside of the underground air duct 11 through the air inlet pipe 4, the fourth connecting pipe 13 and the fourth PVC spring pipe 12. Heat exchange is carried out between the underground air duct 11 and the fresh air. The fresh air inside the underground air duct 11 is introduced into the inside of the heat exchange pipe 55 through the third PVC spring pipe 10, the second connecting pipe 54 and the second square pipe 52. Heat exchange is carried out between the heat exchange pipe 55 and the fresh air. The fresh air inside the heat exchange pipe 55 is sequentially introduced into the inside of the chicken coop 1 through the first square pipe 51, the first connecting pipe 53, the first PVC spring pipe 6, the air guide pipe 7, the second PVC spring pipe 8 and the third connecting pipe 9. The driving of the exhaust fan 2 can extract air inside the third connecting pipe 9, thereby reducing the pressure inside the fresh air supply pipeline. Under the action of the atmospheric pressure, the outside fresh air can be quickly introduced into the fresh air supply pipeline and transported to the inside of the chicken coop 1.
