Technical Field

[0001] The utility model relates to the technical field of air treatment, in particular to an air treatment device for an air inlet channel. Background Art

[0002] Modern pig houses are usually equipped with ventilation structures to keep the air flowing in the pig houses. In order to make the air entering the pig house cleaner, a device for treating the air is usually set on the air inlet channel of the pig house. For example, the patented technology with application number CN202020455923.7 discloses a pig farm with ventilation equipment. This technology is equipped with a dustproof net on the air inlet channel to filter dust in the air and prevent dust from entering the pig house. However, in addition to dust, the air may also contain pathogens. The above patented technology cannot kill the pathogens. The pathogens may enter the pig house with the air and affect the health of the pigs. Utility Model Content

[0003] In order to solve the above problems, the present application provides an air treatment device for an air inlet channel, which can filter the air entering the pig house and disinfect the pathogens in the air, making the air entering the pig house cleaner.

[0004] The purpose of the utility model is achieved through the following technical scheme: an air treatment device for an air inlet channel, comprising a fan, a dust filtering structure, an ultraviolet disinfection lamp, a bacteria filtering structure and a water curtain structure which are arranged inside the air inlet channel and distributed in sequence from the air inlet end to the air outlet end of the air inlet channel; the bacteria filtering structure comprises a plate frame and a filter cloth arranged on the plate frame; the filter cloth comprises an outer layer of non-woven fabric, an intermediate layer of non-woven fabric and an outer layer of melt-blown fabric bonded together in sequence, and the outer layer of non-woven fabric faces the ultraviolet disinfection lamp; the ultraviolet disinfection lamp can irradiate the surface of the dust filtering structure and the filter cloth.

[0005] The utility model filters the pathogens in the air through the filter cloth, and kills the passing air and the pathogens attached to the filter cloth and the dust filtering structure through the ultraviolet disinfection lamp, so that the air entering the pig house is cleaner.

[0006] Furthermore, the dust filtering structure includes a coarse filter and a fine filter, wherein the coarse filter is located near the fan, the coarse filter can filter large-sized debris, and the fine filter can filter dust in the air.

[0007] The pore size of the coarse filter is 0.8-1 cm, and the mesh size of the fine filter is 60-80 meshes.

[0008] The water curtain structure comprises:

[0009] an outer frame having an opening;

[0010] Water curtain paper, installed on the opening;

[0011] A water storage tank is arranged at the upper end of the outer frame, and a through groove communicating with the opening is arranged at the bottom thereof, and the through groove is located directly above the water curtain paper;

[0012] A water distribution block is arranged in the water storage tank and is located directly above the through groove, and is evenly provided with a plurality of vertically penetrating water leakage holes, so that the liquid in the water storage tank flows evenly onto the water curtain paper after passing through the water leakage holes;

[0013] A water collecting chamber, arranged at the lower end of the outer frame, for collecting liquid flowing down from the water curtain paper;

[0014] The water delivery mechanism is connected with the water collecting chamber and the water storage tank, and is used for delivering the liquid in the water collecting chamber to the water storage tank.

[0015] The water curtain structure can cool the air that passes through it and enters the pig house. When the liquid is disinfectant, the water curtain structure can further sterilize the air entering the pig house.

[0016] The upper end of the water curtain paper contacts the lower end of the water distribution block after passing through the through groove, so that when the liquid leaks from the water leakage hole on the water distribution block to the lower surface of the water distribution block, it will not be re-collected, but will flow directly onto the water curtain paper, so that the water flow distributed on the water curtain paper is more uniform.

[0017] As another preferred solution, two baffle plates are arranged in the water storage tank, and the two baffle plates are respectively located on both sides of the through groove, so that an installation groove is formed between the two baffle plates; the water distribution block is arranged in the installation groove.

[0018] In this way, after the liquid in the water storage tank overflows the baffle plate, it will be turned into the installation groove through the two baffle plates, so that the liquid can evenly submerge the water distribution block, further improving the uniformity of water distribution. At the same time, the setting of the baffle plate can also eliminate the influence of fluctuations when the liquid enters the water storage tank on the uniformity of water distribution.

[0019] The through groove is surrounded by a sealing pad, and the water distribution block is pressed on the sealing pad. The sealing pad can prevent the liquid from flowing directly from the through groove to the water curtain paper without being distributed by the water distribution block, thereby affecting the uniformity of the water flow on the water curtain paper.

[0020] The bottom of the opening is tilted to form a guide panel, and a water flow groove connected to the water collecting chamber is arranged on the guide panel. The water flowing down from the water curtain paper can flow down along the guide panel and enter the water collecting chamber from the water flow groove.

[0021] The water delivery mechanism comprises a water pump and a water delivery pipe; the water inlet end of the water pump is connected to the water collecting chamber, and the water outlet end of the water pump is connected to the water storage tank through the water delivery pipe.

[0022] An upper cover is arranged on the top of the outer frame.

[0023] Compared with the prior art, the present application has the following beneficial effects: the utility model filters the pathogens in the air through the filter cloth, and kills the passing air and the pathogens attached to the filter cloth and the dust filter structure through the ultraviolet disinfection lamp; at the same time, the water curtain structure can cool down or further sterilize the air passing through it and entering the pig house, making the air entering the pig house cleaner.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0033] Example

[0034] like Figure 1 As shown, the present embodiment discloses an air treatment device for an air inlet channel, which includes a fan 200, a dust filter structure, an ultraviolet disinfection lamp 500, a germ filter structure 600, and a water curtain structure 700, which are arranged inside the air inlet channel 100 and are sequentially distributed from the air inlet end to the air outlet end of the air inlet channel 100. The above-mentioned components are all fixed on the inner wall of the air inlet channel 100, and the air needs to enter the pig house after passing through the fan 200, the dust filter structure, the ultraviolet disinfection lamp 500, the germ filter structure 600, and the water curtain structure 700 in sequence. When setting, the fan 200, the dust filter structure, the ultraviolet disinfection lamp 500, the germ filter structure 600, and the water curtain structure 700 can also be integrated on a frame to form a whole, so as to facilitate installation in the air inlet channel 100. When installing, the entire device can be installed at the entrance of the air inlet channel 100.

[0035] The dust filtering structure includes a coarse filter 300 and a fine filter 400. The coarse filter 300 is located near the fan 200, and the pore size of the coarse filter 300 is 0.8-1 cm, and the mesh number of the fine filter 400 is 60-80 mesh. The coarse filter 300 can filter large-sized debris in the air, and the fine filter 400 can filter dust particles in the air.

[0036] like Figure 2 , 3As shown, the germ filtering structure 600 includes a plate frame 610 and a filter cloth 620 disposed on the plate frame 610. The filter cloth 620 includes an outer non-woven fabric 621, an intermediate non-woven fabric 622 and an outer melt-blown fabric 623 bonded together in sequence, and the outer non-woven fabric 621 faces the ultraviolet disinfection lamp 500.

[0037] The spacing between the fine filter 400 and the germ filtering structure 600 needs to ensure that the ultraviolet disinfection lamp 500 can effectively irradiate the surface of the fine filter 400 and the filter cloth 620 to disinfect the germs attached to the surface of the fine filter 400 and the filter cloth 620. In addition, the disinfection effect can also be ensured by adjusting the power of the ultraviolet disinfection lamp 500.

[0038] In this embodiment, the pathogens in the air are filtered through the filter cloth 620, and the ultraviolet disinfection lamp 500 is used to sterilize the air flowing through and the pathogens attached to the filter cloth 620 and the dust filtering structure, so that the air entering the pig house is cleaner.

[0039] like Figure 4 , 5 As shown, the water curtain structure 700 includes an outer frame 701, a water curtain paper 702, a water distribution block 703 and a water delivery mechanism. Among them, the middle part of the outer frame 701 has an opening 715, and the water curtain paper 702 is installed on the opening 715. The upper end of the outer frame 701 is also provided with a water storage tank 706, and the water distribution block 703 is installed in the water storage tank 706. Specifically, the bottom of the water storage tank 706 is provided with a through groove 714 connected to the opening 715, and the through groove 714 is located directly above the water curtain paper 702. When installed, the water distribution block 703 is placed directly above the through groove 714. The water distribution block 703 is evenly provided with a plurality of leakage holes 704 that penetrate up and down along its length direction, so that the liquid in the water storage tank 706 can flow evenly to the water curtain paper 702 after the leakage holes 704, thereby forming a water curtain. When the air passes through the water curtain paper 702, the water curtain can cool the air; when the liquid is a disinfectant, the water curtain can disinfect the air.

[0040] In addition, the upper end of the water curtain paper 702 contacts the lower end of the water distribution block 703 after passing through the through groove 714. That is, the height of the water curtain paper 702 is slightly higher than the height of the opening 715, so that after the water curtain paper 702 is installed on the opening 715, the upper end of the water curtain paper 702 can pass through the through groove 714 and contact the lower surface of the water distribution block 703, so that when the liquid leaks from the water leakage hole 704 on the water distribution block 703 to the lower surface of the water distribution block 703, it will not be re-collected, but will directly flow onto the water curtain paper 702, so that the water flow distributed on the water curtain paper 702 is more uniform.

[0041] The lower end of the outer frame 701 is provided with a water collecting chamber 708, which is used to collect the liquid flowing down from the water curtain paper 702. Specifically, the bottom of the opening 715 is inclined to form a guide panel 716, and the lower end of the water curtain paper 702 is fixed on the guide panel 716. In addition, the guide panel 716 is provided with a water trough 717 connected to the water collecting chamber 708. When the liquid flows down from the water curtain paper 702, it can flow downward along the guide panel 716 and enter the water collecting chamber 708 from the water trough 717.

[0042] The water delivery mechanism connects the water collecting chamber 708 and the water storage tank 706, and is used to deliver the liquid in the water collecting chamber 708 to the water storage tank 706 so that the liquid can be recycled. Specifically, the water delivery mechanism includes a water pump 710 and a water delivery pipe. When set, a water pump installation chamber 709 is provided at the lower end of the outer frame 701, and the water pump 710 is installed in the water pump installation chamber 709, and its water inlet end is connected to the water collecting chamber 708, and its water outlet end is connected to the water storage tank 706 through the water delivery pipe.

[0043] As another optional implementation, the water pipe can be arranged inside the side frame of the outer frame 701, and the water pipe can be arranged in a spiral to increase the flow distance of the liquid. When the liquid is used to cool the air, the water flowing over a long distance can cool the air better, so as to facilitate reuse.

[0044] Of course, in a specific implementation, a liquid replenishing port and a liquid draining port may be provided on the outer frame 701 to facilitate replacement of the liquid.

[0045] As another optional implementation, two baffles 705 are provided in the water tank 706, and the two baffles 705 are respectively located on both sides of the through groove 714, so that a mounting groove 712 is formed between the two baffles 705 and the end wall of the water tank 706, and the water distribution block 703 is installed in the mounting groove 712. The height of the two baffles 705 is less than the depth of the water tank 706. When the water delivery mechanism replenishes water into the water tank 706, the liquid gradually overflows the two baffles 705 and enters the mounting groove 712, so that the liquid can evenly submerge the water distribution block 703, further improving the uniformity of water distribution. At the same time, the provision of the baffles 705 can also eliminate the influence of fluctuations on the uniformity of water distribution when the liquid is replenished into the water tank 706.

[0046] As another optional implementation, a sealing gasket 713 is provided around the through groove 714, and the water distribution block 703 is pressed on the sealing gasket 713. The sealing gasket 713 can prevent the liquid from flowing directly from the through groove 714 to the water curtain paper 702 without being distributed by the water distribution block 703, thereby affecting the uniformity of the water flow on the water curtain paper 702.

[0047] In addition, an upper cover 707 is provided on the top of the outer frame 701 , and a seal is provided between the upper cover 707 and the outer frame 701 .

[0048] During installation, the power supply line, the liquid replenishing pipe and the liquid draining pipe of the entire device can all be extended out from the side wall of the air inlet channel, and will not affect the normal ventilation and the normal installation of the device.

[0049] In this embodiment, the filter cloth 620 is used to filter the germs in the air, and the ultraviolet disinfection lamp 500 is used to sterilize the air flowing through and the germs attached to the filter cloth 620 and the dust filter structure, so that the air entering the pig house is cleaner. Of course, the air treatment device of this embodiment can also be applied to the air inlet ducts of other buildings.

[0050] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.
