Description

Technical Field

[0001] This invention relates to the field of environmental protection and pollution control technology for aquaculture, and in particular to a dust removal device, deodorization system and application method for aquaculture sites. Background Technology

[0002] With the rapid development of large-scale, intensive livestock and poultry farming, malodorous gases produced by the decomposition of manure in livestock sheds have become a prominent environmental problem in the industry. The Ministry of Ecology and Environment's "Technical Policy for Pollution Prevention and Control in Livestock and Poultry Farming" clearly states that malodorous gases produced must be treated, and emissions must meet national or local malodorous gas emission standards. Currently, the main methods for treating malodorous gases are water curtain treatment and biological filter tower treatment. However, due to the large footprint and high cost of biological filter towers, they are not suitable for small-scale farming. Therefore, the cheaper and simpler water curtain treatment method has gained wider application.

[0003] The existing utility model patent with authorization announcement number CN223874761U discloses a deodorization device for large-scale farms, which is equipped with a wet curtain made of copolymer polypropylene for deodorization. In actual application, the dust, animal hair and other foreign objects stirred up by the activities of livestock and poultry can easily cause the wet curtain to be blocked and corroded. Therefore, farms will further install a filter device to remove foreign objects.

[0004] For example, the existing utility model patent with authorization announcement number CN222324594U discloses an automatic dust removal device, which is equipped with a spray washing component for cleaning the dust removal filter screen. However, after the filter screen is adhered to by foreign objects and becomes clogged, spray washing and dust removal will result in increased pressure on the filter screen, making it easy to be damaged. Moreover, the cleaning effect is not ideal, and the subsequent filtration effect may even be greatly reduced. Therefore, a more efficient method is needed to ensure the normal operation of the filtration work. Summary of the Invention

[0005] In view of this, the present invention proposes a dust removal device, deodorization system and application method for aquaculture farms that does not require cleaning of the filter screen and can guarantee good filtration effect, in order to solve the problem that the existing filter screen structure is easily damaged due to increased pressure during cleaning and the cleaning effect is not ideal.

The fixing plate is connected to the water tank; The guide rail frame is mounted on the fixed plate, and the filter plate is connected to the guide rail frame; The drum seat is mounted on the guide rail frame and is inserted into the roller.

[0009] Based on the above technical solutions, preferably, the baffle plate includes a ring seat, an angle plate, and a connecting rod, and a retaining ring is provided at the end of the cylinder seat, wherein, The ring seat and the cylinder seat are rotatably connected; The end of the corner plate is connected to the ring seat, the corner plate abuts against the filter media, and the corner plate and the ring seat are provided with a gap groove, with the retaining ring located in the gap groove; One end of the connecting rod is connected to the ring seat, and the other end of the connecting rod is fixed relative to the cylinder seat.

[0010] Based on the above technical solutions, the preferred embodiment of the water supply pipe rack includes a fixed rod, a support, a swing rod, and a spray pipe, wherein... One end of the fixing rod is fixedly connected to the cylinder base; The support is mounted on the cylinder base; One end of the swing arm is rotatably connected to the support; Multiple water spray pipes are installed on both the fixed rod and the swing rod. The water spray pipes on the fixed rod and the swing rod clamp the first water curtain frame from both sides.

[0011] Based on the above technical solutions, preferably, the first water curtain frame includes side plates, support plates, connecting plates, and connecting frames, wherein, The side panels have a rectangular plate structure, and multiple side panels are arranged in a rectangular array. The support plate is set at the corner of the side plate, and the support plate is inclined in the diagonal direction of the side plate and in the direction away from the side plate; The connecting plate connects to the support plate at the corner of the adjacent side plate; The connecting frame is connected to two adjacent connecting plates, and the connecting frame abuts against the water spray pipe.

[0012] Based on the above technical solutions, preferably, the connecting plate is arranged longitudinally and connects to the support plate at the corner of the adjacent side plate.

[0013] On the other hand, the present invention provides a deodorization system, including the dust removal device for breeding farms described above.

[0014] Furthermore, the present invention provides a deodorization system, including the aforementioned deodorization system, and further including a second water curtain frame and a spray frame, wherein, The second water curtain frame is set opposite to the first water curtain frame. The second water curtain frame has the same structure as the first water curtain frame. The density of the side plates in the second water curtain frame is greater than the density of the side plates in the first water curtain frame. The spray frame is set on one side of the second water curtain frame, and the spray frame is equipped with several nozzles corresponding to the second water curtain frame. The nozzles are used to spray chemical liquid.

[0015] Furthermore, the present invention provides a method for applying the above-mentioned deodorization system, comprising the following steps: S1. The dust removal device is arranged longitudinally in the breeding area. The filter media is unwound by the upper winding mechanism and wound up by the lower winding mechanism until the filter screen corresponds to the ventilation fan. S2. Combine the fixed rod and swing rod of the water supply pipe frame to clamp the filter material and the first water curtain frame through the spray pipes on both sides. S3 sprays water through the spray pipe to wet the filter screen, while simultaneously forming a water curtain using the first water curtain frame to filter out dust and animal hair carried in the airflow. S4. Chemical water is sprayed onto the second water curtain frame through the nozzles of the spray frame. The water mist is formed by impact to atomize the airflow and remove odors. As the filter becomes saturated, the filter material is unwound again by the upper unwinding mechanism and wound up by the lower unwinding mechanism until a new filter corresponds to the ventilation fan. At the same time, the membrane between the two filter sections wraps around the used filter.

[0016] The dust removal device, deodorization system, and application method for aquaculture sites of the present invention have the following advantages over the prior art: (1) By setting the filter media into two parts, filter screen and membrane, and setting a winding and unwinding mechanism, the filter screen can be replaced by winding and unwinding after it becomes saturated. Therefore, there is no need to clean the filter screen during application, which helps to ensure good filtration effect. At the same time, by setting a water supply pipe rack, the filter screen can be wetted by water flow, which improves the adsorption effect of the filter screen.

[0017] (2) By setting the first water curtain frame, a water curtain can be formed to work with the filter screen to filter, so as to ensure a good filtration effect. The first water curtain frame can reduce the impact of airflow and water flow on the filter screen. At the same time, the first water curtain frame holds the filter material, and the water supply pipe frame holds the first water curtain frame, so as to ensure good overall structural stability when it is applied, thereby avoiding the filter material from failing due to the influence of airflow and water flow.

[0018] (3) By setting an integrated support structure on the water tank, which is used simultaneously for fixing the baffle plate, installing the filter plate, roller and pipe rack, a high degree of structural integration is achieved, which helps to ensure the convenience of structural integration.

[0019] (4) By setting up a baffle plate, it can hold the filter media and catch the falling debris, so that the debris falls onto the filter plate. This can prevent large debris from entering the angle between the filter media application section and the winding section, and also prevent it from falling into the water tank. It can not only prevent interference with the winding of the filter media, but also effectively prevent it from affecting the subsequent water circulation system.

[0020] (5) In the structure of the water supply pipe rack, there are fixed rods and swing rods. In this way, the swing rods can drive part of the spray pipes and a first water curtain frame to rotate and tilt to one side, thereby releasing the clamping of the filter material by the two first water curtain frames. This can avoid affecting the filter material winding and replacement work.

[0021] (6) By setting up a second water curtain frame and a spray frame, and increasing the density of the side plates of the second water curtain frame, it is easier to form water mist faster, and to achieve deodorization through biological and chemical treatment methods.

[0029] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0030] like Figures 1-11 As shown, the dust removal device for aquaculture farms of the present invention includes filter material 1, a first water curtain frame 2, a water supply pipe frame 3, a roll-up mechanism 4, a water tank 5, a support 6, a baffle plate 7, and a filter plate 8, which is used to filter out foreign objects such as dust and animal hair from the airflow of the farm's exhaust fan.

[0031] like Figure 1 , Figure 5 , Figure 6 and Figure 11As shown, the filter material 1 includes multiple filter screens 11 and multiple membranes 12 connected at intervals; at least two first water curtain frames 2 are provided, and the two first water curtain frames 2 clamp the filter screens 11; the water supply pipe frame 3 clamps the filter material 1 and the first water curtain frames 2, and the water supply pipe frame 3 can be opened and closed; two winding mechanisms 4 are provided, and each of the two winding mechanisms 4 is connected to one end of the filter material 1.

[0032] As described above, in the dust removal device of the present invention, the filter material 1 is installed in accordance with the exhaust fan of the breeding house for the purpose of filtering out foreign objects.

[0033] Specifically, the filter media 1 is arranged in a roll, with roll-up and unrolling structures at both ends. After the filter media 1 has filtered out foreign matter for a period of time, one roll-up and unrolling mechanism 4 rolls up the filter media 1, while the other unrolls it. This allows the unused portion of the filter media 1 to be aligned with the fan to continue dust filtration, while the used portion is rolled up. Thus, the filter media 1 can be used as a disposable product, or the entire roll of filter media 1 can be cleaned using gentler methods after use. This effectively solves the problems of poor filter cleaning effect and damage to the filter screen caused by spray washing.

[0034] Specifically, the filter media 1 consists of two parts: a filter screen 11 and a membrane 12. In application, the filter screen 11 corresponds to the blower to perform filtration. When the filter screen 11 is saturated, it is wound up. After the filter screen 11 is wound up, the winding and unwinding mechanism 4 continues to operate, further covering the wound filter screen 11 with the membrane 12. This prevents debris remaining inside the filter screen 11 from being flushed out and causing blockage in the circulation pipe when water is sprayed from the water supply pipe 3.

[0035] The water supply pipe rack 3 is used to spray water onto the filter screen 11 to improve the filtration effect of impurities and extend the service life of the filter material 1.

[0036] The first water curtain frame 2 is used to contact the water flow sprayed from the water supply pipe frame 3 to reduce the water flow's scouring of the filter screen 11. While wetting the filter screen 11, the first water curtain frame 2 also helps to form a water curtain to improve the filtration effect.

[0037] Specifically, the first water curtain frame 2 is configured as an openable structure, which can hold the filter screen 11 to ensure the stability of the filter screen 11. When the filter screen 11 needs to be rolled up, the first water curtain frame 2 can be opened to avoid interfering with the rolling and replacement of the filter screen 11.

[0038] It should be noted that this solution is effective in removing water-soluble ammonia, volatile fatty acids, and hydrogen sulfide, and therefore can also deodorize to some extent.

[0039] like Figures 1-3As shown, the water tank 5 is located on the lower side of the water supply pipe bracket 3; the bracket 6 is located on the water tank 5; the baffle plate 7 is rotatably mounted on the bracket 6, and the baffle plate 7 partially abuts against the filter material 1; the filter plate 8 is detachably connected to the bracket 6.

[0040] As described above, this solution includes a water tank 5, so that after the water flows down along the filter material 1 and the first water curtain frame 2, it can enter the water tank 5 and then enter the purification circulation system through the water tank 5 to achieve water treatment and recycling.

[0041] Since the end of the filter material 1 is wound by the winding mechanism 4, the application section of the filter material 1 is tangent to the winding section. Therefore, in order to avoid the accumulation of debris in the corner space at the tangent point, a baffle plate 7 is set to hold the filter material 1, so that the debris can slide off the surface of the baffle plate 7, thereby avoiding accumulation and affecting the subsequent winding work.

[0042] Furthermore, a filter plate 8 is installed on the upper part of the water tank 5 to catch debris washed down, preventing it from entering the water tank 5 and affecting the subsequent water circulation system. Of course, fine impurities can still enter the water tank 5 and then the subsequent circulation system, so the purification device used in the circulation system is also equipped with corresponding filtration measures.

[0043] Specifically, the baffle plate 7 and the filter plate 8 are mounted on the water tank 5 via the bracket 6. Since the baffle plate 7 needs to support the filter media 1 during application, in order to avoid affecting the winding of the filter media 1, the baffle plate 7 is set as a rotating structure so that the baffle plate 7 can avoid the filter media 1 when it is being wound up.

[0044] like Figure 2 and Figure 5 As shown, the support 6 includes a fixed plate 61, a guide rail frame 62, and a drum seat 63. The winding mechanism 4 includes a roller 41 for winding the filter material 1. The fixed plate 61 is connected to the water tank 5. The guide rail frame 62 is mounted on the fixed plate 61, and the filter plate 8 is connected to the guide rail frame 62. The drum seat 63 is mounted on the guide rail frame 62, and the drum seat 63 is inserted into the roller 41.

[0045] As described above, in the structure of bracket 6, the fixing plate 61 is used to connect the water tank 5.

[0046] The guide rail frame 62 is connected to the fixed plate 61. The guide rail frame 62 has a sliding groove for inserting the filter plate 8, which facilitates the disassembly, replacement and cleaning of the filter plate 8.

[0047] The roller base 63 is mounted on the guide rail frame 62, which allows it to fit over the end of the roller 41, thereby securing the roller 41 in place. Furthermore, a motor is mounted on the roller base 63 to drive the roller 41.

[0048] like Figure 2 , Figure 7 and Figure 8 As shown, the baffle plate 7 includes a ring seat 71, an angle plate 72, and a connecting rod 73. A retaining ring 631 is provided at the end of the cylindrical seat 63. The ring seat 71 is rotatably connected to the cylindrical seat 63. The end of the angle plate 72 is connected to the ring seat 71. The angle plate 72 abuts against the filter material 1, and the angle plate 72 and the ring seat 71 are provided with a gap groove 701. The retaining ring 631 is located in the gap groove 701. One end of the connecting rod 73 is connected to the ring seat 71, and the other end of the connecting rod 73 is fixed relative to the cylindrical seat 63.

[0049] As described above, the ring seat 71 of the baffle plate 7 is fitted onto the cylindrical seat 63, so that the baffle plate 7 can rotate relative to the cylindrical seat 63 through the ring seat 71, so that the corner plate 72 can move closer to or further away from the filter material 1. The corner plate 72 abuts against the filter media 1, so that when the water carries debris down, it can be guided by the corner plate 72 and fall onto the filter plate 8.

[0050] Furthermore, a connecting rod 73 is provided on the ring seat 71. The connecting rod 73 is used to connect and fix with the cylinder seat 63, for example, by using bolts. With this, the baffle plate 7 can be rotated to avoid movement and can also be locked and fixed.

[0051] The baffle plate 7 is also provided with a spacer groove 701, and the cylinder seat 63 is provided with a retaining ring 631 located in the spacer groove 701. The retaining ring 631 is to abut against the end of the wound part of the filter material 1 to prevent the debris adsorbed on the filter material 1 from flowing out through the end under the influence of water flow, thereby avoiding affecting the subsequent water flow circulation system.

[0052] like Figure 2 , Figure 4 and Figure 5 As shown, the water supply pipe frame 3 includes a fixed rod 31, a support 32, a swing rod 33, and a spray pipe 34. One end of the fixed rod 31 is fixedly connected to the cylinder base 63; the support 32 is set on the cylinder base 63; one end of the swing rod 33 is rotatably connected to the support 32; multiple spray pipes 34 are set on the fixed rod 31 and the swing rod 33, and the spray pipes 34 on the fixed rod 31 and the spray pipes 34 on the swing rod 33 clamp the first water curtain frame 2 from both sides.

[0053] As described above, the water supply pipe rack 3 is used for water spraying so that the water flow can adsorb impurities in the gas.

[0054] Specifically, in the structure of the water supply pipe frame 3, there are fixed rods 31 and swing rods 33 located on opposite sides of the filter material 1, and water spray pipes 34 set on the fixed rods 31 and swing rods 33, so that water can be sprayed onto the filter material 1 and the first water curtain frame 2 through the water spray pipes 34 during operation.

[0055] Furthermore, the water spray pipe 34 is also used to clamp the first water curtain frame 2, which facilitates the integration work.

[0056] Specifically, the water spray pipe 34 on the fixed rod 31 and the water spray pipe 34 on the swing rod 33 each abut against a first water curtain frame 2, thereby clamping the filter material 1 through the two first water curtain frames 2.

[0057] When the filter material 1 needs to be wound up, the swing rod 33 can rotate and tilt to one side, thereby driving the corresponding water spray pipe 34 and the first water curtain frame 2 to move away from the filter material simultaneously, so as to avoid interfering with the winding and replacement of the filter material 1. After the filter material 1 has been wound up and replaced, the swing rod 33 drives the water spray pipe 34 and the first water curtain frame 2 to return to their original positions, and the swing rod 33 and the fixed rod 31 can be connected by fasteners.

[0058] Specifically, a support 32 is provided on the cylinder base 63 for the rotational installation of the swing rod 33. In the fixing structure of the connecting rod 73 of the baffle plate 7, the connecting rod 73 is configured to be connected and fixed to the support 32 by bolts.

[0059] like Figure 9 and Figure 10 As shown, the first water curtain frame 2 includes a side plate 21, a support plate 22, a connecting plate 23, and a connecting frame 24. The side plate 21 has a rectangular plate structure, and multiple side plates 21 are arranged in a rectangular array. The support plate 22 is located at the corner of the side plate 21, and the support plate 22 is inclined towards the diagonal direction of the side plate 21 and away from the side plate 21. The connecting plate 23 connects the support plate 22 at the corner of the adjacent side plate 21. The connecting frame 24 is connected to two adjacent connecting plates 23, and the connecting frame 24 abuts against the water spray pipe 34.

[0060] As described above, the first water curtain frame 2 has multiple parts, among which the side plate 21 is used to deal with the water flow of the water supply pipe frame 3, realize the impact dispersion of the water flow, and help the filter material 1 to be evenly soaked in water.

[0061] The support plate 22 and the connecting plate 23 are used to connect adjacent side plates 21. The support plate 22 is also used to separate the side plates 21 and the filter media 1, so that water flow and impurities can have gaps to contact the filter media 1.

[0062] The connecting plate 23 is also used to set the connecting frame 24, which is used to support the water spray pipe 34, thereby achieving the clamping and fixing of the water spray pipe 34 to the first water curtain frame 2. This also helps to ensure the structural stability of the first water curtain frame 2 and avoid deformation problems of the first water curtain frame 2.

[0063] Furthermore, the water spray pipe 34 is connected to the connecting bracket 24 by fasteners.

[0064] In some embodiments, the connecting plate 23 is arranged longitudinally and connects to the support plate 22 at the corner of the adjacent side plate 21.

[0065] like Figure 10 In the structure shown, the connecting plate 23 is arranged horizontally, while in some embodiments, the connecting plate 23 is arranged vertically, so that when the connecting plate 23 abuts against the filter media 1, it can reduce the obstruction to the downward flow of water and ensure the flushing effect.

[0066] The deodorization system of the present invention includes the dust removal device for breeding farms described above.

[0067] like Figure 12 As shown, the deodorization system of the present invention further includes a second water curtain frame 9 and a spray frame 10. The second water curtain frame 9 is arranged opposite to the first water curtain frame 2. The second water curtain frame 9 and the first water curtain frame 2 have the same structure. The density of the side plate 21 in the second water curtain frame 9 is greater than the density of the side plate 21 in the first water curtain frame 2. The spray frame 10 is arranged on one side of the second water curtain frame 9. The spray frame 10 is provided with a plurality of nozzles corresponding to the second water curtain frame 9. The nozzles are used to spray chemical liquid.

[0068] As described above, the second water curtain frame 9 and the spray rack 10 are used for deodorization. The spray rack 10 is configured to spray chemical liquid, and the second water curtain frame 9 is configured to carry biological carriers. In this way, deodorization can be achieved through chemical or biological means, or a combination of chemical and biological means can be used to achieve deodorization.

[0069] Specifically, the second water curtain frame 9 adopts the same structure as the first water curtain frame 2. The difference is that the side plates 21 in the second water curtain frame 9 have a higher density, or, to put it another way, the second water curtain frame 9 has more side plates 21, support plates 22, connecting plates 23 and connecting frames 24 in the same area.

[0070] In practical applications, a semi-enclosed treatment room is set up outside the breeding house, the air outlet of the breeding house fan is located inside the semi-enclosed treatment room, the dust removal device is set up corresponding to the air outlet of the fan, and the second water curtain frame 9 and the spray frame 10 are located on the other side of the semi-enclosed treatment room.

[0071] During operation, the airflow first passes through the dust removal device for dust removal and filtration, filtering out larger debris, and then enters between the dust removal device and the second water curtain frame 9. At this time, the spray frame 10 sprays chemical water solution onto the second water curtain frame 9. The water solution impacts the spray frame 10 and forms a suspended water mist in the semi-enclosed treatment room, so as to fully contact the airflow input by the fan, thereby ensuring sufficient reaction time to improve the deodorization effect.

[0072] The increased density of the side plate 21 helps to achieve more water impact to form water mist.

[0073] The method of applying the deodorization system of the present invention includes the following steps: S1. The dust removal device is arranged longitudinally in the breeding area, and the filter material 1 is unwound by the upper unwound mechanism 4, while the filter material 1 is wound up by the lower unwound mechanism 4 until the filter screen 11 corresponds to the ventilation fan. S2. Combine the fixed rod 31 and swing rod 33 of the water supply pipe frame 3 to clamp the filter material 1 and the first water curtain frame 2 through the spray pipes 34 on both sides.
