Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to a device for purifying and eliminating odors in livestock sheds. Background Technology

[0002] Livestock and poultry farming is a crucial pillar industry of my country's agricultural economy. However, under intensive farming models, large amounts of dust, harmful gases (such as ammonia and hydrogen sulfide), and pathogenic microbial aerosols are continuously generated in the farms. These pollutants not only seriously endanger the health of livestock and poultry, leading to frequent respiratory diseases and decreased productivity, but also create foul odors and pollute the surrounding environment, becoming a key issue restricting the industry's green and sustainable development.

[0003] To improve the indoor environment, existing air purification technologies mainly employ the following methods:

[0004] Chemical spraying: This method masks odors or kills microorganisms by spraying chemical deodorizers or disinfectants into the air. This method has a short-lived effect, may leave chemical residues, and long-term use can lead to microbial resistance and poses a risk of secondary pollution.

[0005] Physical adsorption method: such as using activated carbon filters. This method has a certain adsorption effect on some odors in the initial stage, but the adsorption capacity is limited, it is easily saturated, requires frequent replacement of filter media, has high operation and maintenance costs, and may become a source of pollution after saturation.

[0006] Single ultraviolet disinfection method: This method involves simply installing ultraviolet lamps to irradiate the air. While primarily focused on inactivating microorganisms, it offers no dust filtration, and the lamp surface is easily and rapidly covered by high concentrations of dust within the building, causing a sharp decline in ultraviolet intensity and resulting in unstable disinfection effectiveness. More importantly, ordinary ultraviolet lamps have limited ability to decompose gaseous odor molecules, failing to fundamentally eliminate odors.

[0007] In summary, existing technologies either fail to thoroughly purify (only removing odors but not dust, or only disinfecting but not odors), may cause secondary pollution, or suffer from cumbersome maintenance and rapid performance degradation. Therefore, there is an urgent need to develop an air purification device for livestock sheds that can simultaneously and efficiently remove particulate matter, thoroughly decompose odors, and efficiently inactivate microorganisms, while also being stable in operation and easy to maintain. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model relates to an air purification and odor elimination device for livestock sheds, comprising a rectangular duct with an air inlet and an air outlet. U-shaped seats are installed on the two opposite inner sides of the rectangular duct, and several ultraviolet lamps are installed between the two U-shaped seats. A control box is installed on the outer side of the rectangular duct, and a control switch on the control box is connected to the power supply terminal of the ultraviolet lamps via a conductive wire. A detachable filter assembly is installed inside the air inlet of the rectangular duct.

[0010] Furthermore, the end of the ultraviolet lamp is connected to a lamp tube mounting base, which is fixed to the U-shaped base.

[0011] Furthermore, the filter assembly includes a rectangular frame with a stepped surface on the inner wall of the rectangular frame. A filter screen is installed inside the rectangular frame, and the filter screen is limited by the stepped surface and a limiting strip installed inside the rectangular frame.

[0012] Furthermore, an annular groove is provided on the outer side of the rectangular frame, and at least two oppositely distributed first screw holes are provided on the air inlet, with the ends of screws installed on the first screw holes extending into the annular groove.

[0013] Furthermore, an elastic element is installed at the end of the U-shaped seat, and the elastic element pushes the filter assembly to slide out of the air inlet.

[0014] Furthermore, the elastic element includes a mounting bracket, a movable top rod is mounted in the middle of the mounting bracket, one end of the top rod is provided with a convex ring, the other end of the top rod is provided with an external thread, a limit nut is installed on the threaded end of the top rod, a spring sleeved on the top rod is limited by the convex ring, and the spring pushes one end of the top rod to extend to one side of the filter assembly.

[0015] Furthermore, the U-shaped base is provided with a second screw hole, and the end of the mounting bracket extends into the port of the U-shaped base. The screw installed in the second screw hole fixes the end of the mounting bracket.

[0016] This utility model has the following beneficial effects:

[0017] (1) This utility model adopts a two-stage purification mode that combines "pre-filtering physical filtration" and "post-filtering ultraviolet photolysis oxidation". The pre-filtering effectively intercepts large particles such as dust and hair, as well as some microorganisms, which not only directly improves the visible cleanliness of the air, but also provides a clean working environment for the downstream ultraviolet lamp, avoiding the lamp tube from being contaminated and its efficiency from decreasing.

[0018] (2) The filter assembly of this utility model adopts a detachable slot and screw fixing design, and innovatively sets up an elastic ejection mechanism driven by a spring. When it is necessary to clean or replace the filter screen, only a small number of screws need to be loosened, and the filter assembly can automatically partially pop out under the action of spring force, which greatly facilitates the operator's grasping and maintenance, and reduces the labor intensity and time cost of daily maintenance. At the same time, the main purification unit (ultraviolet lamp) is firmly installed on the inner wall of the air duct through a U-shaped seat, and the wiring is concentrated in the control box. The structure is compact and has strong anti-vibration ability, ensuring the stability and reliability of long-term operation in the complex environment of the breeding house.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] like Figures 1-6 As shown, the air purification and odor elimination device for the breeding shed includes a rectangular air duct 1. One end of the rectangular air duct 1 is provided with an air inlet 101, and the other end is provided with an air outlet 102, forming a main channel for air circulation. An air intake fan can be installed at the air inlet 101, or a negative pressure air outlet fan can be installed at the air outlet 102.

[0031] To achieve deep air purification, U-shaped seats 2 are symmetrically installed on a pair of opposing inner surfaces inside the rectangular duct 1. The two U-shaped seats 2 extend along the length of the duct and together support several ultraviolet lamps 3. These ultraviolet lamps 3 are preferably lamps capable of emitting UVC band ultraviolet light, whose emitted short-wave ultraviolet light can effectively decompose organic molecules in the air and kill bacteria and viruses. Each ultraviolet lamp 3 has a lamp mounting bracket 301 connected to its end, which is fixed to the corresponding U-shaped seat 2, ensuring that the lamp is securely installed and the electrical connection is reliable.

[0032] A control box 5 is installed on the outer wall of the rectangular duct 1. The control box 5 integrates components such as power supply and control circuit, and its panel is equipped with a control switch. The control box 5 is connected to the power supply terminal of each UV lamp 3 through the conductive wire 4 laid inside the duct, so as to realize the unified power supply and control of all UV lamps 3.

[0033] like Figure 4 As shown, a detachable filter assembly 6 is installed inside the air inlet 101 of the rectangular duct 1 to initially filter large particulate dust, hair, and other pollutants from the air. This filter assembly 6 includes a rectangular frame 601. An annular stepped surface is machined on the inner wall of the rectangular frame 601, and the filter screen 602 is placed on this stepped surface. Furthermore, a limiting strip 603 is installed on the inner side of the rectangular frame 601. Through the cooperation between the stepped surface and the limiting strip 603, the filter screen 602 is firmly secured within the rectangular frame 601, preventing it from loosening or falling off during use.

[0034] To facilitate the installation and fixation of the filter assembly 6, a ring groove is provided on the outer surface of the rectangular frame 601. Correspondingly, at least two oppositely distributed first screw holes 1011 are provided on the pipe wall of the air inlet 101. During installation, the rectangular frame 601 of the filter assembly 6 is inserted into the air inlet 101, and then screws are screwed in through the first screw holes 1011, with the ends of the screws precisely pressing into the ring groove on the outer side of the rectangular frame 601. This connection method achieves quick fixation, avoids drilling holes in the rectangular frame, maintains its structural integrity, and also facilitates disassembly, cleaning, or filter replacement.

[0035] like Figures 5-6 As shown, to facilitate the automatic pop-out of the auxiliary filter assembly 6 during disassembly for easy handling by the operator, an elastic element 7 is installed at the end of the U-shaped seat 2 near the air inlet 101. This elastic element 7 includes a fixed part and a movable part. Specifically, the elastic element 7 has a mounting bracket 701, through which an axially movable push rod 702 is mounted. One end of the push rod 702 has a raised ring, and the other end is machined with external threads. A spring 703 is fitted onto the push rod 702, with one end of the spring 703 limited by the raised ring. A limit nut 704 is installed on the threaded end of the push rod 702 to adjust and limit the maximum stroke of the push rod. After installation, the spring 703 is in a compressed state, and its elastic force pushes the raised ring end of the push rod 702 towards the filter assembly 6 with a constant tendency.

[0036] The end of the U-shaped seat 2 is provided with a second screw hole 201. During installation, the end of the mounting bracket 701 of the elastic element 7 is inserted into the port of the U-shaped seat 2, and then a screw is screwed in through the second screw hole 201 to fasten the end of the mounting bracket 701 to the U-shaped seat 2, thereby completing the installation of the entire elastic element 7.

[0037] Working principle:

[0038] After the device is started, the polluted air in the breeding shed, driven by the negative pressure fan, enters the rectangular air duct 1 through the air inlet 101. The air first passes through the filter assembly 6, where dust, suspended particles, and other contaminants are intercepted by the filter screen 602. The preliminarily purified air continues to flow to the middle of the air duct, where it is irradiated with high-intensity ultraviolet light emitted by the array of ultraviolet lamps 3. The ultraviolet light can destroy the DNA / RNA of microorganisms, rendering them inactive, and can also photolyze odor gas molecules into harmless small molecules. Finally, the purified clean air is discharged from the air outlet 102 and circulated back into the breeding shed, achieving the purpose of continuous air purification and odor elimination.

[0039] These ultraviolet lamps 3 preferably emit dual-band ultraviolet light of 185nm and 254nm, and they are arranged along the airflow direction to form a strong ultraviolet radiation field.

[0040] When the filter 602 needs to be cleaned or replaced, simply loosen the fixing screw on the air inlet 101. The spring 703 in the compressed elastic element 7 will immediately release its elastic force, pushing the push rod 702 forward. The front end of the push rod 702 acts on the rectangular frame 601 of the filter assembly 6, causing it to slide outward a short distance and partially pop out of the air inlet. The operator can easily remove it for maintenance.

[0041] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
