Description

Technical Field

[0001] The utility model relates to the technical field of ventilation structures, in particular to a duck house ventilation structure for duck breeding. Background Art

[0002] Duck is a bird of the Anatidae family in the order Anseriformes. Ducks are covered with feathers, with a large and round head without a crown, wattles or earlobes; a long and flat beak with serrated keratinized protrusions on the edges of the upper and lower jaws; a long neck that allows for free movement; a long, wide, boat-shaped body with an erect forequarters, plump feathers, small wings and long aileron feathers; short legs with webbed toes, and bare toes and webbed parts for swimming; male ducks have hooked sex feathers, a short tail, and well-developed uropygial glands; and a well-developed penis that is protruding and spiral-shaped.

[0003] Ducks need to be raised in duck houses, but when the duck house is in use, the duck feces and the smell of the ducks themselves will cause an unpleasant smell in the duck house. Usually, the staff will install a ventilation structure on the duck house to ensure the air quality in the duck house, but the ventilation structure currently used only relies on fans to extract air to achieve ventilation in the duck house. The exhausted odor cannot be filtered, which will still affect the staff to a certain extent. Adding a gas filtration device alone will increase the breeding cost. For this reason, we propose a duck house ventilation structure for duck breeding. Utility Model Content

[0004] The purpose of the utility model is to provide a duck house ventilation structure for duck breeding, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a duck house ventilation structure for duck breeding, comprising an exhaust duct, an exhaust fan is arranged inside the exhaust duct, a deodorization component for filtering the odor of the duck house is arranged on the right side of the exhaust duct, and the deodorization component is composed of a spray filter component for spraying and a diversion component for gas-liquid separation.

[0006] Preferably, the spray filtering assembly comprises: a capillary tube, the left side of the capillary tube passes through the right side of the exhaust pipe and is fixed to the exhaust pipe, the bottom of the capillary tube is passed through by a water pipe and fixedly connected to the water pipe, the water pipe is inserted into a water tank, and utilizing the Bernoulli principle, when the odorous gas in the duck house is drawn into the exhaust pipe by the exhaust fan, the gas then enters the capillary tube via the exhaust pipe, the gas flow rate entering the capillary tube increases, and the pressure decreases, and under the influence of the pressure, the water in the water tank enters the capillary tube through the water pipe, and because the capillary tube has a certain length, the water entering the capillary tube can be mixed with the odor, thereby absorbing the odor in the gas and achieving a filtering effect, thereby effectively avoiding discomfort to the staff when the odor is discharged, and improving the air quality in the duck house.

[0007] Preferably, the diversion component comprises a disc, a cavity is provided inside the disc, and the right side of the capillary penetrates through the disc and is fixedly connected to the disc.

[0008] Preferably, an impeller is rotatably installed on the inner wall of the cavity, an air outlet is provided at the top of the disc, a water outlet is provided at the bottom of the disc, and the blades of the impeller are in a fit with the inner wall of the disc. The principle is consistent with that of a gear pump. When the gas and liquid in the capillary enter the cavity in the disc, the gas impacts on the impeller. Due to the fast gas flow rate, the impeller rotates, and the gas and liquid entering the cavity enter between the blades of the impeller and rotate with the impeller. At this time, the gas and liquid are separated by a certain degree of centrifugal force. When the impeller rotates nearly one circle, the gas and liquid between the impeller blades move to between the air outlet and the water outlet, and the filtered gas is discharged from the air outlet and the liquid is discharged from the water outlet, thereby realizing gas-liquid separation.

[0009] Preferably, a bracket is fixed to the bottom of the disc by bolts, and the disc can be supported by the bracket, so that the entire device can be installed in the duck house conveniently.

[0010] Preferably, a filter plate is fixedly installed on the left side of the exhaust duct, and the gas pumped by the exhaust fan can be filtered by the filter plate to prevent debris such as duck feathers from being pumped into the exhaust duct by the exhaust fan.

[0011] Compared with the prior art, the utility model provides a duck house ventilation structure for duck breeding, which has the following beneficial effects:

[0012] 1. The ventilation structure of the duck house for duck breeding uses the Bernoulli principle through the spraying and filtering components. When the odorous gas in the duck house is drawn into the exhaust pipe by the exhaust fan, it enters the capillary tube through the exhaust pipe. The gas flow rate into the capillary tube increases and the pressure decreases. Under the influence of the pressure, the water in the water tank enters the capillary tube through the water pipe. Since the capillary tube has a certain length, the water entering the capillary tube can be mixed with the odor, thereby absorbing the odor in the gas and achieving the filtering effect, thereby effectively avoiding discomfort to the staff when the odor is discharged, improving the air quality in the duck house, and having low cost and easy use.

[0013] 2. The ventilation structure of the duck house for duck breeding has a diversion component set up. When the gas and liquid in the capillary enter the cavity in the disc, the gas impacts on the impeller. Due to the fast gas flow rate, the impeller rotates, and the gas and liquid entering the cavity enter between the blades of the impeller and rotate with the impeller. At this time, the gas and liquid are separated by a certain degree of centrifugal force. When the impeller rotates nearly one circle, the gas and liquid between the impeller blades move to between the air outlet and the water outlet. The filtered gas is discharged from the air outlet and the liquid is discharged from the water outlet to achieve gas-liquid separation. The staff only needs to place a collection bucket under the water outlet to collect the wastewater for irrigation or other operations, which is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a duck house ventilation structure for duck breeding, comprising an exhaust duct 1, an exhaust fan 2 is arranged inside the exhaust duct 1, a deodorizing component for filtering the odor of the duck house is arranged on the right side of the exhaust duct 1, the deodorizing component is composed of a spraying filter component 3 for spraying and a diverter component 4 for gas-liquid separation, a filter plate 6 is fixedly installed on the left side of the exhaust duct 1, and the gas pumped by the exhaust fan 2 can be filtered by the arranged filter plate 6 to prevent debris such as duck feathers from being pumped into the exhaust duct 1 by the exhaust fan 2.

[0020] The spraying and filtering assembly 3 comprises: a capillary tube 31, the left side of the capillary tube 31 passes through the right side of the exhaust pipe 1 and is fixed to the exhaust pipe 1, the bottom of the capillary tube 31 is passed through by a water pipe 32 and is fixedly connected to the water pipe 32, the water pipe 32 is inserted into a water tank 33, and by using the Bernoulli principle, when the odorous gas in the duck house drawn by the exhaust fan 2 enters the exhaust pipe 1, it enters the capillary tube 31 through the exhaust pipe 1, the gas flow rate entering the capillary tube 31 increases, and the pressure decreases. Under the influence of the pressure, the water in the water tank 33 enters the capillary tube 31 through the water pipe 32. Since the capillary tube 31 has a certain length, the water entering the capillary tube 31 can be mixed with the odor, thereby absorbing the odor in the gas and achieving a filtering effect, thereby effectively avoiding discomfort to the staff when the odor is discharged, and improving the air quality in the duck house.

[0021] The flow dividing component 4 includes a disc 41, a cavity 42 is formed inside the disc 41, a bracket 5 is fixed to the bottom of the disc 41 by bolts, the disc 41 can be supported by the bracket 5, and the device can be conveniently installed in the duck house as a whole. The right side of the capillary 31 passes through the disc 41 and is fixedly connected to the disc 41. An impeller 43 is rotatably installed on the inner wall of the cavity 42. An air outlet 44 is formed on the top of the disc 41, and a water outlet 45 is formed on the bottom of the disc 41. The blades of the impeller 43 are in a fitting state with the inner wall of the disc 41. The principle is consistent with that of a gear pump. When the gas in the capillary 31 is When the gas and liquid enter the cavity 42 in the disc 41, the gas impacts the impeller 43. Due to the fast gas flow rate, the impeller 43 rotates, and the gas and liquid entering the cavity 42 enter between the blades of the impeller 43 and rotate with the impeller 43. At this time, the gas and liquid are separated by a certain degree of centrifugal force. When the impeller 43 rotates nearly one circle, the gas and liquid between the blades of the impeller 43 move to between the air outlet 44 and the water outlet 45. The filtered gas is discharged from the air outlet 44, and the liquid is discharged from the water outlet 45, thereby realizing gas-liquid separation.

[0022] Based on the above implementation mode, first, a hole is drilled on the wall of the duck house where the device is to be installed, and the exhaust pipe 1 is installed so that the capillary 31 is outside the duck house. After the exhaust pipe 1 and the capillary 31 are installed, the water tank 33 is placed at the bottom of the water pipe 32, and the water tank 33 is filled with water so that the water pipe 32 extends below the liquid level inside the water tank 33. The bracket 5 is installed at the bottom of the disc 41 by bolts to lift the disc 41 to ensure the stability of the disc 41.

[0023] After the overall installation of the device is completed, start the exhaust fan 2. The exhaust fan 2 draws the gas in the duck house into the exhaust pipe 1. After the odorous gas enters the exhaust pipe 1, it enters the capillary 31 through the exhaust pipe 1. The gas flow rate entering the capillary 31 increases and the pressure decreases. Under the influence of pressure, the water in the water tank 33 enters the capillary 31 through the water pipe 32. Since the capillary 31 has a certain length, the water entering the capillary 31 can be mixed with the odor, thereby absorbing the odor in the gas and achieving a filtering effect, thereby effectively avoiding discomfort to the staff when the odor is discharged and improving the air quality in the duck house.

[0024] As the gas and liquid continue to move, when the gas and liquid in the capillary 31 enter the cavity 42 in the disc 41, the gas impacts the impeller 43. Due to the fast gas flow rate, the impeller 43 rotates, and the gas and liquid entering the cavity 42 enter between the blades of the impeller 43 and rotate with the impeller 43. At this time, the gas and liquid are separated by a certain degree of centrifugal force. When the impeller 43 rotates nearly one circle, the gas and liquid between the blades of the impeller 43 move to between the air outlet 44 and the water outlet 45. The filtered gas is discharged from the air outlet 44 and the liquid is discharged from the water outlet 45, thereby realizing gas-liquid separation. The staff only needs to place a collection bucket under the water outlet 45 to collect the wastewater for irrigation or other operations, which is convenient to use.

[0025] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
