Description

Technical Field

[0001] This utility model relates to the field of air purification technology in livestock farming, and in particular to a ventilation and deodorization device for livestock farming. Background Technology

[0002] Timely ventilation and deodorization in livestock farming can improve air quality, provide animals with sufficient oxygen, promote metabolism, and reduce the concentration of harmful gases. Livestock farming produces harmful gases such as ammonia, hydrogen sulfide, and carbon dioxide. Ventilation can reduce these gases, not only reducing odors but also preventing respiratory diseases in animals.

[0003] A search of Chinese patent CN220674729U reveals a ventilation, deodorization, and sterilization device for livestock ecological breeding sheds, relating to the field of livestock and poultry breeding technology. This utility model includes: a sleeve and a mounting cover; the sleeve is fixedly embedded in the roof of the breeding shed, and the mounting cover is connected to the top of the sleeve, with a blower installed at the end of the mounting cover furthest from the sleeve; an inner cylinder, slidably inserted into the bottom side of the sleeve, with activated carbon embedded inside; a hollow plate symmetrically connected to both sides of the bottom of the inner cylinder, with air hoods evenly spaced on both sides of the hollow plate, and air holes evenly spaced at the bottom of the air hoods; and a lifting mechanism mounted on the sleeve to drive the inner cylinder up and down. Compared to traditional deodorization devices, this utility model is smaller in size and can be directly installed on the roof of the breeding shed, without occupying breeding space. Furthermore, the lifting mechanism, combined with the air hoods, improves the ventilation and deodorization effect of the breeding shed, making it highly practical.

[0004] However, in implementing the relevant technology, the above-mentioned deodorizing and sterilizing device has the following problems: the existing technology uses activated carbon to adsorb odors in the air, but the adsorption capacity of activated carbon is limited. After a period of use, if the activated carbon is not replaced in time, the deodorizing effect will be greatly reduced. Therefore, the existing technology requires frequent replacement of activated carbon, which is not convenient to use. Based on this, this utility model designs a ventilation and deodorizing device for livestock breeding to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a ventilation and deodorization device for livestock farming, so as to solve the problem mentioned in the background art that the existing technology requires frequent replacement of activated carbon and has poor ease of use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a ventilation and deodorization device for livestock breeding, comprising a fixed base plate, a support shaft rotatably connected to the fixed base plate, a support frame installed at one end of the support shaft, support rings respectively installed on the support frame, a limit cover installed on the top outer wall of the support ring, and an activated carbon block placed inside the limit cover;

[0007] A support frame is installed on the top outer wall of the fixed base plate, and an electric push rod is installed on the top outer wall of the support frame. An upper sealing cover is connected to the output end of the electric push rod.

[0008] A lower sealing cover is slidably engaged on the fixed base plate. A fixing frame is installed on the bottom outer wall of the fixed base plate. An electric push rod II is installed on the bottom outer wall of the fixing frame. The output end of the electric push rod II is connected to the lower sealing cover.

[0009] As a preferred embodiment, an air intake pipe is installed on the mounting bracket, and one end of the air intake pipe is connected to the lower sealing cover via a plastic hose.

[0010] As a preferred embodiment, an exhaust fan is installed on one side wall of the support frame, and the input end of the exhaust fan is connected to the upper sealing cover via a plastic hose.

[0011] As a preferred embodiment, a drive motor is installed on the bottom outer wall of the fixed base plate, and the output end of the drive motor is connected to one end of the support shaft.

[0012] As a preferred embodiment, a sealing plate is installed on the top outer wall of the lower sealing cover, and sealing gaskets are attached to both the upper surface of the sealing plate and the lower surface of the upper sealing cover.

[0013] As a preferred embodiment, a support vertical rod for auxiliary support of the support base is installed on the bottom outer wall of the support base.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] By rotating the support base, another limiting cover can rotate to the bottom of the upper sealing cover. Then, the electric push rod one drives the upper sealing cover to descend and press against the upper surface of the adjusted limiting cover. The electric push rod two drives the lower sealing cover to press against the lower surface of the corresponding support ring. Then the device can continue to deodorize. By automatically replacing the activated carbon blocks, the device can not only ensure the deodorization effect of the air, but also eliminate the need for workers to frequently replace the activated carbon blocks, thus improving the ease of use of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-5The illustrated ventilation and deodorization device for livestock farming includes a fixed base plate 1, a support shaft 3 rotatably connected to the fixed base plate 1, a support frame 4 mounted at one end of the support shaft 3, support rings 5 ​​mounted on the support frame 4, the support frame 4 having a cross-shaped structure, with a support ring 5 mounted on each branch, a limit cover 6 mounted on the top outer wall of the support ring 5, and activated carbon blocks 7 placed inside the limit cover 6, a support frame 2 mounted on the top outer wall of the fixed base plate 1, and an electric push rod 9 mounted on the top outer wall of the support frame 2. An upper sealing cover 10 is connected to the output end of electric push rod 9. A lower sealing cover 8 is slidably engaged with the fixed base plate 1. A fixed frame 13 is installed on the bottom outer wall of the fixed base plate 1. An electric push rod 12 is installed on the bottom outer wall of the fixed frame 13. The output end of electric push rod 12 is connected to the lower sealing cover 8. An air inlet pipe 14 is installed on the fixed frame 13. Each air inlet pipe 14 has an air inlet hole. One end of the air inlet pipe 14 is connected to the lower sealing cover 8 through a plastic hose. An exhaust fan is installed on one side wall of the support frame 2. 15. The input end of the exhaust fan 15 is connected to the upper sealing cover 10 via a plastic hose. When using this device, the exhaust fan 15 first draws air to create a negative pressure inside the upper sealing cover 10, allowing air to enter through the air inlet on the air inlet pipe 14. Then, after being adsorbed and deodorized by the activated carbon block 7 inside the limiting cover 6, the air is discharged through the exhaust port of the exhaust fan 15. After the device has been used for a period of time, the upper sealing cover 10 is moved upward by the electric push rod 19, and the lower sealing cover 8 is moved upward by the electric push rod 212. Moving downwards allows the support base 4 to rotate, thereby rotating the other limiting cover 6 below the upper sealing cover 10. Then, the electric push rod 19 drives the upper sealing cover 10 to descend and press against the upper surface of the adjusted limiting cover 6. At the same time, the electric push rod 212 drives the lower sealing cover 8 to press against the lower surface of the corresponding support ring 5, thus completing the replacement of the activated carbon block 7. Therefore, this device does not require workers to frequently replace the activated carbon block 7, and it can also ensure the deodorization effect on the air, thereby improving the ease of use of the device.

[0024] In this embodiment, as Figure 2 As shown, a drive motor 16 is installed on the bottom outer wall of the fixed base plate 1. The output end of the drive motor 16 is connected to one end of the support shaft 3. The drive motor 16 can drive the support shaft 3 to rotate, thereby enabling the support shaft 3 to drive the support base frame 4 to rotate.

[0025] In this embodiment, as Figure 5 As shown, a sealing plate 11 is installed on the top outer wall of the lower sealing cover 8. A sealing gasket 17 is attached to the upper surface of the sealing plate 11 and the lower surface of the upper sealing cover 10. The sealing plate 11 helps to increase the contact area between the lower sealing cover 8 and the support ring 5, and the sealing gasket 17 helps to improve the sealing effect of the upper sealing cover 10 and the lower sealing cover 8.

[0026] In this embodiment, as Figure 2 As shown, a support vertical rod 18 for auxiliary support of the support base 4 is installed on the bottom outer wall of the support base 4. The support vertical rod 18 provides auxiliary support to the support base 4, which helps to improve the stability of the support base 4 when it rotates.

[0027] Working principle of this utility model: This utility model is a ventilation and deodorization device for livestock breeding. The exhaust fan 15 draws air to create a negative pressure inside the upper sealing cover 10, so that air can enter through the air inlet on the air inlet pipe 14, and then be deodorized by the activated carbon block 7 inside the limiting cover 6 before being discharged through the exhaust port of the exhaust fan 15.

[0028] After a period of use, the electric push rod 19 moves the upper sealing cover 10 upward, while the electric push rod 212 moves the lower sealing cover 8 downward. Then, by rotating the support base 4, the other limiting cover 6 can rotate to below the upper sealing cover 10. Next, the electric push rod 19 moves the upper sealing cover 10 down to abut the upper surface of the adjusted limiting cover 6, and the electric push rod 212 moves the lower sealing cover 8 to abut the lower surface of the corresponding support ring 5. Then the device can continue to deodorize. By automatically replacing the activated carbon block 7, the device can not only ensure the deodorization effect of the air, but also eliminate the need for workers to frequently replace the activated carbon block 7, thus improving the ease of use of the device.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
