Description

Technical Field

[0001] This utility model belongs to the field of duck farming, and relates to duck houses, and in particular to a ventilation device for duck houses. Background Technology

[0002] Existing duck farming is generally divided into two types: indoor farming and free-range farming. Indoor farming is generally a fully enclosed farming method. The entire duck house needs to control the environment such as sunlight, temperature, and humidity. It also requires continuous manual cleaning of manure, water supply, and feed supply.

[0003] For example, a ventilation structure for duck houses in duck farming, disclosed in CN222786720U, includes an exhaust pipe with an exhaust fan inside. A deodorizing component for filtering odorous gases from the duck house is located on the right side of the exhaust pipe. This ventilation structure, through its spray filtration component, utilizes Bernoulli's principle. When the odorous gas drawn from the duck house by the exhaust fan enters the exhaust pipe, it then passes through the exhaust pipe into a thin tube. The gas velocity increases and the pressure decreases in the thin tube. Under this pressure, water from a water tank enters the thin tube through a water pipe. Because the thin tube has a certain length, the water entering the thin tube can mix with the odorous gas, thus absorbing the odor and achieving filtration. This effectively prevents discomfort to workers caused by odorous gas discharge, improves the air quality in the duck house, and is low-cost and easy to use.

[0004] The aforementioned cases used water filtration to remove odors from the adsorbed gas, but water filtration is a poor method of deodorization. Utility Model Content

[0005] This invention provides a ventilation device for duck houses that improves deodorization by filtering gases with activated carbon.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a duck house ventilation device, including a house body, a plurality of ventilation ducts are fixedly connected inside the house body, a fan is fixedly connected inside each ventilation duct, an installation box is fixedly connected inside the ventilation duct, the installation box is filled with activated carbon filler, a filter water tank with the same number as the ventilation ducts is fixedly connected inside the house body, the end of the ventilation duct away from the fan extends into the filter water tank, and an exhaust pipe extending to the outside of the duck house is fixedly connected to the filter water tank.

[0007] A further preferred embodiment of this utility model is as follows: several through holes are provided on both the side walls of the mounting box near and away from the fan, and the through holes on the side walls are staggered.

[0008] A further preferred embodiment of this utility model is that an opening is provided on one side of the mounting box on the ventilation duct.

[0009] A further preferred embodiment of this utility model is as follows: a limiting rod is slidably connected inside the opening, and a groove is provided on the inner sidewall of the opening to facilitate the sliding of the limiting rod.

[0010] A further preferred technical solution of this utility model is as follows: both ends of the limiting rod are provided with locking blocks, and the inner wall of the sliding groove is provided with a locking groove to facilitate the locking blocks to be inserted. When the locking blocks are inserted into the locking groove, the limiting rod is located on the radial central axis of the opening.

[0011] A further preferred embodiment of this utility model is as follows: the filter tank is filled with filtrate, the end of the ventilation duct away from the fan extends into the filtrate, and the end of the exhaust pipe near the filtrate is located above the filtrate.

[0012] A further preferred embodiment of this utility model is: a dehumidification box is fixedly connected inside the exhaust pipe, and the dehumidification box contains calcium chloride desiccant.

[0013] A further preferred embodiment of this utility model is: a drain outlet is provided on the filter water tank, and a piston is detachably connected inside the drain outlet.

[0014] Compared with the prior art, this utility model includes a duck house, in which several ventilation ducts are fixedly connected. Each ventilation duct is fixedly connected to a fan, and a mounting box is fixedly connected to the ventilation duct. The mounting box is filled with activated carbon. Filter water tanks, the same number as the ventilation ducts, are fixedly connected to the duck house. The end of the ventilation duct away from the fan extends into the filter water tank, and an exhaust pipe extending to the outside of the duck house is fixedly connected to the filter water tank. By setting activated carbon, odors in the air drawn into the ventilation ducts can be removed, thereby purifying the air. Activated carbon has a good deodorizing effect, which can effectively improve the purification effect. At the same time, activated carbon can preliminarily filter impurities such as feed particles and duck feathers mixed in the air. The deodorized air is then transported to the filter water tank for further impurity removal, further improving the air purification effect, thus making the exhaust air purer and fresher.

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0019] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0020] Figures 1-7 As shown, a duck house ventilation device includes a house body 1, and several ventilation ducts are fixedly connected inside the house body 1. At least four ventilation ducts are provided, which can effectively improve the ventilation effect and avoid poor ventilation affecting the breeding of ducks.

[0021] Figures 1-7 As shown, the ventilation duct includes a thick pipe 9 and a thin pipe 10. A fan 6 is fixedly connected inside the thick pipe 9. A mounting box 8 is fixedly connected to one side of the fan 6 on the thick pipe 9. One side of the mounting box 8 abuts against the thin pipe 10. At this time, the mounting box 8 is sandwiched between the fan 6 and the thin pipe 10, which can effectively limit the range of motion of the mounting box 8 and prevent the mounting box 8 from shifting when filtering air. The mounting box 8 is filled with activated carbon 7 filler.

[0022] Figures 1-7As shown, during the breeding process, when the fan 6 is turned on, the fan 6 can draw the air in the house 1 into the ventilation duct, thereby speeding up the air exchange. At this time, the air first enters the coarse pipe 9. When it passes through the coarse pipe 9, the activated carbon 7 in the coarse pipe 9 can absorb the odor in the air, thereby purifying the air and preventing the exhaust gas from having an irritating odor that affects the environment. Figures 1-7 As shown, at the same time, the gaps between the activated carbon particles 7 can effectively intercept impurities such as feed particles or duck feathers in the air, perform preliminary filtration of the air, and further improve the air purification effect.

[0023] Figures 1-7 As shown, the mounting box 8 has several through holes on both sides of the side wall near and away from the fan 6, and the through holes on the side walls are staggered.

[0024] Figures 1-7 As shown, air can smoothly enter the mounting box 8 through the through holes for filtration, while the staggered through holes can prevent the activated carbon 7 from leaking out through the through holes.

[0025] Figures 1-7 As shown, an opening 11 is provided on one side of the mounting box 8 on the ventilation duct. The mounting box 8 can be easily replaced through the opening 11, thereby ensuring the air filtration effect.

[0026] Figures 1-7 As shown, a limiting rod 12 is slidably connected inside the opening 11. A groove 15 is provided on the inner side wall of the opening 11 to facilitate the sliding of the limiting rod 12. After the installation box 8 is replaced, the limiting rod 12 is slid into the opening 11 until the limiting rod 12 is located at the radial central axis of the opening 11. At this time, the limiting rod 12 can effectively block the installation box 8 and prevent the installation box 8 from falling out through the opening 11.

[0027] Figures 1-7 As shown, both ends of the limiting rod 12 are provided with locking blocks 14, and the inner wall of the slide groove 15 is provided with a slot 13 to facilitate the locking blocks 14 to be inserted. When the locking blocks 14 are inserted into the slots 13, the limiting rod 12 is located on the radial central axis of the opening 11. By setting the locking blocks 14 and the slots 13, the limiting rod 12 can be fixed on the radial central axis of the opening 11, so as to prevent the limiting rod 12 from sliding when filtering air.

[0028] Figures 1-7 As shown, the same number of filter water tanks 3 as the ventilation ducts are fixedly connected inside the building 1. The end of the ventilation duct away from the fan 6 extends into the filter water tank 3. An exhaust pipe 2 extending to the outside of the duck house is fixedly connected to the filter water tank 3. The filter water tank 3 is filled with filtrate 4, which is water. The end of the ventilation duct away from the fan 6 extends into the filtrate 4. The end of the exhaust pipe 2 near the filtrate 4 is located above the filtrate 4.

[0029] Figures 1-7 As shown, the gas filtered by activated carbon 7 in the coarse pipe 9 enters the filter water tank 3 through the thin pipe 10. At this time, the filter liquid 4 in the filter water tank 3 filters the gas again, further removing impurities in the air, thus making the air purer. The filtered gas is discharged from the shed 1 through the exhaust pipe 2, and the air purification is completed. This design makes the discharged air fresher and purer, effectively avoiding the problem of odor pollution in the duck shed and effectively protecting environmental hygiene.

[0030] Figures 1-7 As shown, a dehumidification box 5 is fixedly connected inside the exhaust pipe 2. The dehumidification box 5 contains calcium chloride desiccant. When the gas is discharged through the exhaust pipe 2, the gas passes through the dehumidification box 5 for dehumidification, thereby drying the gas.

[0031] Figures 1-7 As shown, the filter tank 3 is provided with a drain outlet, and a piston is detachably connected inside the drain outlet. The filter liquid 4 in the filter tank 3 can be replaced in a timely manner through the drain outlet, thereby ensuring the filtration effect of the filter liquid 4.
