Description

Technical Field

[0001] The invention relates to the technical field of pig farm epidemic prevention, and in particular to an integrated device for automatic replacement and disinfection of epidemic prevention filter cotton in a pig farm. Background Art

[0002] In recent years, China's livestock farming industry has experienced rapid growth, with its annual output value reaching 10.8 trillion yuan in 2024. This achievement is primarily driven by the rise of highly industrialized modern agricultural farms, which have replaced the traditional free-range farming model of individual farmers. This large-scale, intensive farming method not only reduces costs but also improves food safety, successfully fulfilling the task of supplying approximately 700 million pigs annually to 1.4 billion people. However, this high-density farming model also brings new challenges, particularly the crucial issue of airborne disease control. Since the outbreak of African swine fever (ASF) in 2018, the livestock farming industry has suffered devastating losses. How to effectively control respiratory diseases such as ASF and blue ear disease through airborne disease control has become a critical issue that the livestock farming industry urgently needs to address.

[0003] Traditional pig farm air filtration systems mostly rely on manual filter replacement and cleaning. However, this approach has numerous drawbacks. First, frequent manual replacement and cleaning not only consumes significant manpower and time, but also increases labor costs. Second, manual operations make it difficult to ensure thorough cleaning, which can easily lead to pathogens or contaminants remaining on the filter re-entering the piggery, causing secondary contamination and posing a potential threat to pig health. Furthermore, the disinfection process of traditional filtration systems is complex, making it difficult to guarantee disinfection effectiveness. This is especially true when dealing with highly contagious diseases like African swine fever, posing an extremely high risk for epidemic prevention.

[0004] Most existing filter replacement and disinfection devices on the market are single-function and cannot simultaneously meet the needs of automatic replacement and disinfection, making them difficult to adapt to the efficient epidemic prevention requirements of modern pig farms. Therefore, developing a device that can achieve automatic filter replacement and disinfection is of great significance for improving pig farm epidemic prevention efficiency, reducing epidemic prevention costs, and ensuring pig health.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] Example 1:

[0042] Refer to the attached Figures 1-10 The invention relates to an integrated device for automatically replacing and disinfecting filter cotton for epidemic prevention in pig farms, comprising a shell 1 with an open front, a protective net 2 provided on the front of the shell 1, a fan 3 installed on the back of the shell 1, a partition plate 4 provided inside the shell 1, and a plurality of embedded openings provided inside the partition plate 4, and at least two sets of filtering mechanisms 6 provided on the partition plate 4;

[0043] The present invention also has a feature of real-time monitoring of parameters such as air volume, pressure difference, inlet air temperature, humidity, and quality to prevent problems such as mismatch between operating air volume and actual demand, high energy consumption, inability to detect filter leakage in time, increased risks in normal production, and risks of delayed maintenance;

[0044] The filter mechanism 6 includes a hollow shaft 61 disposed inside the housing 1 and a rotating member for rotating the hollow shaft 61. The outer surface of the hollow shaft 61 is provided with a plurality of filter elements 65. The hollow shafts 61 in the two filter mechanisms 6 are connected by a belt assembly 5.

[0045] It should be noted here that the filter element 65 includes two filter ends; by providing a plurality of filter elements 65 on the outer surface of the hollow shaft 61, it is convenient to filter the fresh air generated by the fan 3, and by rotating the hollow shaft 61 through the rotating member, the two filter ends of the plurality of filter elements 65 can be switched in position. The hollow shafts 61 in the two filter mechanisms 6 are connected by the belt group 5, so that when one of the hollow shafts 61 rotates, the other hollow shafts 61 can be driven to rotate synchronously, thereby forming a plurality of groups of filter elements 65. The two filter ends of the filter elements 65 are switched in position;

[0046] The rotating member includes but is not limited to an electric motor or other rotating mechanism that rotates and drives one of the hollow shafts 61, and each rotation of the rotating member is a semicircle, which facilitates the position conversion of the two filter ends of the filter element 65, forming automatic replacement and automatic disinfection, thereby solving the problems of the prior art that frequent replacement or cleaning is required, which increases labor and material costs, and is difficult to disinfect, and incomplete cleaning can easily lead to secondary contamination.

[0047] The interior of the housing 1 is provided with a cleaning mechanism for cleaning the filter element 65 , the cleaning mechanism including a cleaning member 7 for cleaning the unused filter element 65 and a water injection member 8 for injecting water into the unused filter element 65 ;

[0048] Through the setting of the cleaning structure, not only can disinfectant water be injected into the interior of the hollow shaft 61 to disinfect the filter end to be cleaned in the filter element 65 with the disinfectant water, but the filter end to be cleaned in the filter element 65 can also be disinfected and cleaned mechanically, thereby further improving the filtering effect of the filter mechanism 6.

[0049] Refer to the attached Figure 8 The filter element 65 includes two guide frames 651 fixedly connected to the outer surface of the hollow shaft 61, and one end of each guide frame 651 is fixedly connected to a filter cover 652, and the interior of the filter cover 652 is fixedly connected to a filter cotton block 654 through a wire mesh 653, and a sealing ring is provided at one end of the filter cover 652;

[0050] The two guide frames 651 are used to discharge the fresh air and disinfectant water inside the hollow shaft 61 into the two filter covers 652 respectively. The injected fresh air can cooperate with the filter cotton block 654 to perform filtering work, and the injected disinfectant water can disinfect the filter cotton block 654 after long-term use.

[0051] The steel mesh 653 is provided to further improve the stability of the filter cotton block 654 after installation, improve the stability of the filter cotton block 654 during use, and improve the stability during subsequent cleaning.

[0052] It should be noted here that the setting of the sealing ring is used to improve the sealing effect after the filter cover 652 is embedded in the embedded opening inside the partition plate 4, to prevent pathogens from entering the pig house through the gap when the sealing is not tight or poor, especially when highly infectious diseases such as African swine fever (ASF) are prevalent, the risk is extremely high.

[0053] Refer to the attached Figure 9 , two adjusting cylinders 64 are fixedly connected to the inner top of the shell 1, and the telescopic ends of the two adjusting cylinders 64 are fixedly connected to the inner side of the partition plate 4, and the adjusting cylinders 64 are used to adjust the horizontal direction of the partition plate 4;

[0054] The adjusting cylinder 64 adopts the telescopic cylinder in the existing technology, which is connected to the external power supply and control system, and is used to drive the telescopic adjustment of the partition plate 4. By adjusting the position of the partition plate 4, the filter cover 652 embedded in the partition plate 4 is facilitated to be removed, thereby improving the orderliness of the position conversion of the two filter covers 652 in the filter element 65.

[0055] Refer to the attached Figure 5 、 Figure 7 and Figure 8 A hollow fixed shaft 62 is fixedly connected to the interior of the housing 1, and the hollow shaft 61 is rotatably connected to the outer surface of the fixed shaft 62 through a sealed bearing. A vertical partition 63 is fixedly connected to the interior of the fixed shaft 62. The vertical partition 63 is used to separate the interior of the fixed shaft 62 into an air chamber and a water chamber. The outer surface of the fixed shaft 62 is provided with a guide port communicating with the interior of the two guide frames 651, and the two guide ports are respectively communicated with the interior of the air chamber and the water chamber;

[0056] The hollow shaft 61 is rotatably connected to the outer surface of the fixed shaft 62 through a sealed bearing, which not only facilitates the rotation of the hollow shaft 61, but also facilitates the support of the hollow shaft 61 through the fixed shaft 62;

[0057] By fixing a vertical partition 63 to the interior of the fixed shaft 62, the interior of the fixed shaft 62 can be divided into an air chamber and a water chamber. The air chamber and the water chamber are respectively used to inject fresh air and disinfectant water into the interiors of the two filter covers 652 in the filter element 65. The filter covers 652 in use can filter and drain the fresh air, and the injected disinfectant water can disinfect and clean the interiors of the filter covers 652 to be cleaned in the filter element 65.

[0058] When the two filter covers 652 in the filter element 65 are switched in position, the air cavity and the water cavity thereof can automatically switch their connection positions, thereby ensuring the orderliness of water and air injection, without the need for electric or manual adjustment, thereby improving the convenience and practicality of operation;

[0059] It should be noted here that the vertical partition 63 can be made of heat-conducting material, so that when a high-temperature water source is injected to perform high-temperature disinfection on the filter cover 652 to be treated, the high-temperature water source can exchange heat with the fresh air gas, and the introduced fresh air can form a heating work, and then form a fresh air temperature regulation work, which meets the breeding work in winter.

[0060] Refer to the attached Figure 8 and Figure 9 , the two filter covers 652 in the filter element 65 are each provided with a drain port 655, and the inner side surface of the partition plate 4 is fixedly connected with a plurality of sealing blocks 656 for shielding the drain ports 655 on the filter covers 652 in the filtering use state;

[0061] The drain port 655 is provided to discharge the wastewater generated during the disinfection and cleaning process through the sewage discharge mechanism in the water injection member 8. The sealing block 656 is provided to seal and block the filter cover 652 in the filtering state, ensuring that the gas inside the filter cover 652 can only be discharged through the position of the filter cotton block 654, thus forming a fresh air filtering operation.

[0062] It should be noted that the two filter covers 652 in the filter element 65 are arranged in a symmetrical manner, but the positions of the discharge ports 655 on the two filter covers 652 are opposite to each other. Figure 8 shown.

[0063] Refer to the attached Figure 2-Figure 5 and Figure 7 The interior of the housing 1 is fixedly connected to an air collecting hood 9, and a sterilizing lamp is fixedly installed inside the air collecting hood 9. The bottom of the air collecting hood 9 is fixedly connected to a U-shaped air duct 11 through an air guide frame 10. The U-shaped air duct 11 is connected to the interior of the air cavity of the fixed shaft 62; the air collecting hood 9 is used to collect the fresh air introduced by the fan 3, and discharge the fresh air into the air cavity of the fixed shaft 62 through the air guide frame 10 and the U-shaped air duct 11;

[0064] By setting up the air collecting hood 9, the fresh air generated by the fan 3 can be collected, and the living pathogens in the fresh air can be killed by the built-in sterilization lamp tube. The fresh air is then discharged to the U-shaped air duct 11 through the air guide frame 10, and then discharged to the plurality of filter mechanisms 6 through the U-shaped air duct 11 for fresh air filtration.

[0065] It should be noted here that fresh air is injected into the air cavity of the fixed shaft 62 through the U-shaped air duct 11, and the fresh air can directly enter the filter element 65 in use to perform filtering and air guiding work.

[0066] Example 2: Based on Example 1, the difference is that;

[0067] Refer to the attached Figure 5 and Figure 6 The water injection member 8 includes a water injection main pipe 81 fixed to the inside of the shell 1, and at least one branch water pipe 82 is fixedly connected to the water injection main pipe 81. The branch water pipes 82 are all connected to the water chambers of the fixed shafts 62;

[0068] One end of the water injection main pipe 81 extends to the outside of the shell 1 and is connected to the disinfection and sterilization water source through a pipeline. The water injection main pipe 81 is set to inject disinfection water into the interior of several branch water pipes 82, so that the disinfection water enters the water cavity inside the fixed shaft 62, and finally enters the filter cover 652 to be disinfected. When the disinfection water enters the inner side of the filter cover 652, the inner side of the filter cotton block 654 can be self-disinfected and cleaned.

[0069] Several water receiving trays 83 and a sewage main pipe 84 are fixedly connected to the interior of the housing 1, and the several water receiving trays 83 are fixedly connected through a collection frame 85. The sewage main pipe 84 is used to discharge the collected sewage to the outside of the housing 1.

[0070] The arrangement of several water receiving trays 83 is used to receive the sewage disinfected and cleaned by multiple groups of filtering mechanisms 6, and the sewage is collected through the collection frame 85 and uniformly discharged through the sewage main pipe 84, which has a good self-draining function.

[0071] Example 3: Based on Example 1, the difference is that;

[0072] Refer to the attached Figure 9 and Figure 10 , so the cleaning member 7 is arranged on a mounting frame 71 at the top of the housing 1, and the bottom of the mounting frame 71 is slidably connected to a sliding frame 73 through two guide rods 72, and one side of the sliding frame 73 is fixedly connected to a plurality of elastic telescopic plates 74, and the telescopic ends of the plurality of elastic telescopic plates 74 are fixedly connected to pressing rollers 75, and the outer surfaces of the plurality of pressing rollers 75 are fixedly connected to brush fibers, and the bottom of the mounting frame 71 is fixedly connected to an electric telescopic rod 76 for driving the sliding frame 73 up and down;

[0073] The pressing roller 75 is connected to the sliding frame 73 by an elastic telescopic plate 74, so that the elastic force of the elastic telescopic plate 74 can be used to elastically squeeze the filter cotton block 654 inside the filter cover 652. The sliding frame 73 can be driven up and down by the activation of the electric telescopic rod 76. The up and down movement of the sliding frame 73 can drive the pressing rollers 75 to move up and down. The up and down movement of the pressing rollers 75 can squeeze out the sewage in the filter cotton block 654 during the water injection and flushing process, thereby further improving the disinfection and cleaning work of the filter cotton block 654. The cleaning effect of the filter cotton block 654 can be further enhanced by cooperating with the brush fiber, and the filter cotton block 654 has a good self-cleaning function.

[0074] The inner top of the housing 1 is rotatably connected to a rotating shaft 77, and the outer surface of the rotating shaft 77 is fixedly connected to a toggle frame 78. Both ends of the toggle frame 78 are rotatably connected to hinged frames 79. The two hinged frames 79 are respectively hinged to the inner side of the partition plate 4 and the mounting frame 71. The mounting frame 71 is slidably connected to the inner top of the housing 1 through a sliding guide rail.

[0075] When the partition plate 4 is driven to move laterally by adjusting the cylinder 64, one of the hinged frames 79 can be driven to move in a fan-shaped manner, which can then be rotated by the toggle frame 78, and finally the mounting frame 71 of the cleaning member 7 can be driven to move laterally in the opposite direction by the other hinged frame 79, thus having the function of synchronous extension operation;

[0076] By moving the partition plate 4 sideways, the filter element 65 in use can be moved out from the inside of the embedded opening, and by moving the cleaning element 7 sideways in the opposite direction, the cleaning end of the cleaning element 7 can be moved out from the inside of the filter element 65 in the unused state, thereby improving the convenience and smoothness of the subsequent position conversion of the two filter elements 65, not only avoiding the partition plate 4 or the cleaning element 7 from interfering with the filter element 65 during the conversion process, but also facilitating the two filter elements 65 to perform normal filtering or cleaning and disinfection work.

[0077] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
