[0002] Heating in livestock sheds plays a crucial role in livestock production, directly affecting the health, productivity, and profitability of livestock. For small and medium-sized farms, hot air devices or infrared lamps are economical and practical options.

[0003] During livestock and poultry farming, the air quality inside the livestock shed directly affects the health of livestock and poultry. Traditional heating devices only provide a heat source and cannot effectively filter dust, pathogens and harmful gases in the air, which can easily lead to the spread of respiratory diseases.

[0004] To address the aforementioned problems, this utility model document proposes a livestock shed heating device with a filtration function. Utility Model Content

[0005] This invention provides a livestock shed heating device with a filtration function, which solves the shortcomings of existing technologies where traditional heating devices only provide a heat source and cannot effectively filter dust, pathogens and harmful gases in the air, which can easily lead to the spread of respiratory diseases.

[0006] This utility model provides the following technical solution:

[0007] A livestock shed heating device with filtration function includes:

[0008] The livestock shed body has a hot air blower installed outside the air inlet. The hot air blower is reinforced to the ground by a fixed frame at the bottom. The output end of the hot air blower is connected to the air inlet, and the input end of the hot air blower is connected to a filter tube. The filter tube is equipped with a multi-layer filter assembly. The multi-layer filter assembly includes a metal mesh filter that is detachably installed at the other end of the filter tube to intercept large dust particles. Three slots are provided through one side of the filter tube. A HEPA filter element, an activated carbon layer, and a photocatalyst mesh loaded with nano-titanium dioxide are slidably installed in the three slots in sequence.

[0009] The livestock shed is equipped with a ventilation fan at its air outlet, and the air outlet of the ventilation fan is detachably fitted with a chemical catalyst mesh loaded with an ozone decomposition catalyst.

[0010] In one possible design, the metal mesh filter is installed at the inlet of the filter tube by mounting bolts at the four corners. The mounting bolts pass through the mounting holes on the metal mesh filter and are threadedly connected to the threaded grooves on the side wall of the filter tube.

[0011] In one possible design, one side of the main frame of the HEPA filter, activated carbon layer and photocatalyst mesh extends to the outside of the corresponding slot. A vertical block is welded and fixed at the slot. The vertical block is reinforced to the corresponding main frame by a fixing bolt. The fixing bolt passes through a reserved hole on the vertical block and is threadedly connected to a threaded hole on the corresponding main frame.

[0012] In one possible design, an ultraviolet lamp for irradiating the photocatalyst mesh is installed inside the filter tube, and the power cord of the ultraviolet lamp extends to the outside of the filter tube.

[0013] In one possible design, three hooks are fixedly arranged in a ring array on the main frame of the chemical catalyst mesh, and a handle that cooperates with the corresponding hooks is fixedly arranged on the housing of the ventilation fan.

[0014] In one possible design, the inner wall of the chemical catalyst mesh main frame is fixedly provided with positioning posts, and the side wall of the ventilation fan housing is provided with positioning grooves for inserting the corresponding positioning posts.

[0015] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0016] The working principle and usage process of this technical solution are as follows:

[0017] During use, outside air is drawn into the filter tube from the end furthest from the air inlet of the livestock shed by the hot air blower. The air first passes through a detachable metal mesh filter, which intercepts large dust particles in the air, preventing them from entering the livestock shed. Then, the air passes sequentially through a HEPA filter element that slides in a slot on one side of the filter tube, an activated carbon layer, and a photocatalytic mesh loaded with nano-titanium dioxide. The HEPA filter element further filters out fine particles in the air (filtering PM2.5 and microorganisms such as bacteria and viruses); the activated carbon layer adsorbs harmful gases in the air (NH3, H2S, etc.); and the photocatalytic mesh, under the irradiation of ultraviolet lamps, produces a catalytic reaction, catalytically decomposing residual VOCs (such as methane and sulfides).

[0018] Clean air, filtered through multiple layers of filters, enters the air inlet of the livestock shed through the output of the hot air blower, providing warm and clean air to the shed and achieving the heating function. The air inside the shed is exhausted from the air outlet by the ventilation fan. The exhausted air passes through a chemical catalyst mesh loaded with MnO2 / γ-Al2O2 catalyst that can be detached from the air outlet of the ventilation fan. The chemical catalyst mesh decomposes any residual ozone in the air into oxygen, preventing ozone from causing secondary pollution to the environment.

[0019] This utility model has the following beneficial effects:

[0020] In this invention, a multi-layer filter assembly filters dust, pathogens, and harmful gases from the air. For example, a metal mesh filter intercepts large dust particles, a HEPA filter filters fine particles, an activated carbon layer adsorbs harmful gases, and a photocatalytic mesh decomposes harmful substances, thereby reducing the spread of respiratory diseases in livestock and poultry and protecting their health.

[0021] This invention filters the air at the air inlet to prevent pollutants from entering the livestock shed and reduce pollution to the environment inside the shed; the chemical catalyst mesh at the air outlet decomposes residual ozone and converts it into oxygen, reducing pollution to the atmospheric environment.

[0022] In this invention, all filter components and chemical catalyst screens adopt a detachable structure. For example, the metal mesh filter screen is fixed by mounting bolts, the filter components are installed by slots and fixing bolts, and the chemical catalyst screen is connected by hooks and handles, which facilitates regular cleaning and replacement and reduces maintenance costs.

[0031] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0032] Example 1

[0033] Please refer to Figure 1-5 A heating device, comprising:

[0034] The livestock shed body 1 has an air inlet 2 on one side and an air outlet 6 on the other side. A hot air blower 3 is installed outside the air inlet 2 of the livestock shed body 1. The hot air blower 3 is an axial flow fan with a rated power of 5kW. It integrates three sets of U-shaped nickel-chromium alloy electric heating tubes. The electric heating tubes are arranged in a ring array at the air outlet of the blower casing. When a 380V three-phase power supply is connected, the current flows through the high resistivity nickel-chromium alloy wire. According to Joule's law, Q=I 2 Rt generates heat. The bottom of the hot air blower 3 is reinforced to the ground by the fixing frame 5 to ensure the stability of the hot air blower 3 during operation. The output end of the hot air blower 3 is connected to the air inlet 2.

[0035] The input end of the hot air blower 3 is connected to a filter tube 4. The filter tube 4 is equipped with a multi-layer filter assembly. A metal mesh filter 9 is detachably installed at one end of the filter tube 4 to intercept large dust particles. The metal mesh filter 9 is installed at the opening of the filter tube 4 by mounting bolts 10 at the four corners. The mounting bolts 10 pass through the mounting holes on the metal mesh filter 9 and are threadedly connected to the threaded grooves on the side wall of the filter tube 4. When it is necessary to clean or replace the metal mesh filter 9, simply unscrew the mounting bolts 10 to remove the metal mesh filter 9.

[0036] Three slots 8 are provided through one side of the filter tube 4. HEPA filter element 11, activated carbon layer 12 and photocatalytic mesh 13 loaded with nano titanium dioxide (substrate is 20 mesh stainless steel wire mesh, surface is sprayed with nano titanium dioxide coating) are slidably installed in the three slots 8. The main frame of HEPA filter element 11, activated carbon layer 12 and photocatalytic mesh 13 extends to the outside of the corresponding slot 8. Vertical block 14 is welded and fixed at the slot 8. Vertical block 14 is reinforced with the corresponding main frame by a fixing bolt 15. The fixing bolt 15 passes through the reserved hole on the vertical block 14 and is threadedly connected to the threaded hole on the corresponding main frame. When it is necessary to clean or replace HEPA filter element 11, activated carbon layer 12 or photocatalytic mesh 13, the corresponding fixing bolt 15 is unscrewed and the corresponding filter unit is pulled out from the slot 8.

[0037] The filter tube 4 is also equipped with an ultraviolet lamp 16 for irradiating the photocatalyst mesh 13. The power cord 17 of the ultraviolet lamp 16 extends through the filter tube 4 and is connected to an external power source to power the ultraviolet lamp 16 so that it can work normally.

[0038] A ventilation fan 7 (industrial exhaust fan) is installed at the air outlet 6 of the livestock shed body 1. A chemical catalyst mesh 18 loaded with an ozone decomposition catalyst (the catalyst carrier is honeycomb alumina with a loading of 5% MnO2) is detachably installed at the air outlet end of the ventilation fan 7. Three hooks 19 are fixedly arranged in a ring array on the main frame of the chemical catalyst mesh 18. A handle 20 that cooperates with the corresponding hooks 19 is fixedly installed on the shell of the ventilation fan 7. The chemical catalyst mesh 18 and the ventilation fan 7 can be detachably connected by the cooperation of the hooks 19 and the handles 20.

[0039] In use, turn on the hot air blower 3 and the ventilation fan 7. Under the suction of the hot air blower 3, outside air enters the filter tube 4 from the end away from the air inlet 2 of the livestock shed body 1. The air first passes through the metal mesh filter 9, which intercepts large dust particles in the air and prevents them from entering the livestock shed body 1. Then, the air passes through the HEPA filter element 11, activated carbon layer 12, and photocatalyst mesh 13, which are slidably installed in the slot 8 on one side of the filter tube 4. The HEPA filter element 11 further filters the fine particles in the air, such as PM2.5 and microorganisms such as bacteria and viruses. The activated carbon layer 12 adsorbs harmful gases in the air, such as NH3 and H2S. Under the irradiation of the ultraviolet lamp tube 16, the photocatalyst mesh 13 produces a catalytic reaction, catalytically decomposing residual VOCs (such as methane and sulfides).

[0040] Clean air filtered through multiple layers of filters enters the air inlet 2 of the livestock shed body 1 through the output end of the hot air blower 3, providing warm and clean air to the livestock shed body 1 and realizing the heating function. The air inside the livestock shed body 1 is discharged from the air outlet 6 under the action of the ventilation fan 7. The discharged air passes through the chemical catalyst screen 18 at the air outlet of the ventilation fan 7. The chemical catalyst screen 18 decomposes any residual ozone in the air into oxygen, avoiding secondary pollution of the environment by ozone. In daily maintenance, the mounting bolts 10 can be unscrewed periodically to remove the metal mesh filter screen 9 for cleaning; the fixing bolts 15 can be unscrewed to pull out the HEPA filter element 11, activated carbon layer 12 or photocatalyst screen 13 from the slot 8 for cleaning or replacement; the chemical catalyst screen 18 can also be removed for cleaning or replacement by separating the hook 19 from the handle 20, reducing maintenance costs.

[0041] This application can be used for livestock shed heating, or for other fields applicable to this application.

When installing the chemical catalyst mesh 18, the positioning posts 21 are inserted into the positioning grooves 22, and then the hooks 19 are fastened to the handles 20 to complete the installation of the chemical catalyst mesh 18 and ensure the accuracy of the installation position of the chemical catalyst mesh 18.
