Description

Technical Field

[0001] This invention relates to the field of aquaculture environment control technology, and in particular to a heat exchanger for air cooling in aquaculture farms. Background Technology

[0002] In intensive livestock farming, high summer temperatures are a major environmental factor leading to heat stress in livestock and poultry, reduced production performance (such as slower weight gain, decreased egg / milk production, and reduced fertility), and even mortality. Traditional cooling methods for livestock farms have many limitations: evaporative cooling systems become significantly less effective in high humidity, and continuous evaporation consumes a large amount of water; the evaporative cooling structure is also prone to clogging and bacterial growth. Direct air conditioning, while providing stable cooling, is extremely energy-intensive, making it unbearable to operate in the large spaces of livestock farms, and the high dust levels quickly clog air conditioning filters. While misting cooling is simple and easy, it increases ambient humidity, has limited effectiveness in enclosed or poorly ventilated sheds, and may also lead to damp bedding and disease.

[0003] Heat exchange technology, as an energy-saving cooling solution, theoretically utilizes indirect heat exchange between a low-temperature medium and hot air. However, conventional heat exchangers face severe challenges in the unique environment of livestock farms: the abundance of particulate matter such as feathers and feed dust in the air easily clogs the flow channels and fins of the heat exchanger; high humidity and corrosive gases accelerate the corrosion of metal components; improperly treated condensate during cooling can cause secondary pollution; more importantly, existing heat exchangers are difficult to maintain, often requiring shutdown, disassembly, and cleaning after clogging, severely impacting the continuity of livestock production. These problems significantly restrict the practical application of heat exchange technology in the field of livestock environmental control. Summary of the Invention

Detailed Implementation

[0021] The invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figures 1 to 5 As shown, the present invention provides an embodiment: a heat exchanger for air cooling in a livestock farm, comprising a housing 1, an air outlet pipe 2 connected to the upper surface of the housing 1, a heat exchange element 3 disposed on the air outlet pipe 2, an air inlet hopper 11 disposed at the bottom of the housing 1, the air inlet hopper 11 being connected to the air outlet of the livestock farm, the air outlet pipe 2 being connected to the air inlet of the livestock farm, a first circulation fan 12 disposed at the air outlet of the air inlet hopper 11, a venturi tube 4 disposed on the first circulation fan 12, a limiting member 5 disposed on the top surface of the housing 1 for limiting and pressing the venturi tube 4, the limiting member 5 being connected to the air inlet of the air outlet pipe 2, a moving member 6 disposed at the bottom of the housing 1 for moving the venturi tube 4 left and right, a cleaning member 7 disposed at the right end of the upper surface of the housing 1 for cleaning the venturi tube 4, and a filter element 8 disposed inside the venturi tube 4.

[0023] Among them, the housing 1 refers to the shell structure used to house the various components of the heat exchanger. Specifically, it can be formed by welding or assembling metal plates. The housing provides basic support for the internal airflow channels and component installation.

[0024] Among them, the air outlet pipe 2 refers to the pipe that connects to the upper surface of the box and delivers cooled air outward. Specifically, it can be a metal pipe with a circular or rectangular cross section. The air outlet pipe serves as the exhaust channel for the cooled air and is combined with the heat exchanger to achieve the heat exchange function.

[0025] Among them, heat exchanger 3 refers to the heat exchange unit installed on the gas outlet pipe. Specifically, it can be formed by multiple parallel arranged copper gas pipes and partition plates to form a counter-current heat exchange structure, and heat transfer is achieved through indirect contact between low temperature medium and hot air.

[0026] Among them, the air intake hopper 11 refers to the funnel-shaped air intake device installed at the bottom of the box and connected to the exhaust end of the breeding farm. Specifically, it can adopt a conical metal shell. The air intake hopper centrally guides the dust-laden hot air into the internal processing area of ​​the box.

[0027] The first circulating fan 12 refers to the airflow driving device installed at the air outlet of the air inlet bucket. Specifically, it can be an axial flow fan, which enhances the flow speed of hot air in the Venturi tube by forced air delivery.

[0028] Among them, the Venturi tube 4 refers to a fluid acceleration device with a contraction-expansion structure. Specifically, it can be formed by splicing two arc tubes to form a variable diameter channel, using the Bernoulli effect to increase the airflow speed and generate a negative pressure area to promote dust separation.

[0029] Among them, the limiting component 5 refers to the mechanism that is fixed to the top of the box and constrains the position of the venturi tube. Specifically, it can be an electric telescopic rod connected with a corrugated pipe. The alignment accuracy between the venturi tube and the cleaning component is maintained by adjusting the height of the lifting sleeve.

[0030] Among them, the moving part 6 refers to the mechanical device that drives the horizontal displacement of the venturi tube. Specifically, it can be a synchronous motor that drives the screw to drive the moving block to reciprocate, and prevent dust from accumulating in a specific area of ​​the venturi tube through periodic displacement.

[0031] Among them, the cleaning component 7 refers to the device for removing the adhering substances on the surface of the venturi tube. Specifically, it can use high-pressure air jets in conjunction with a liftable collection hopper to achieve non-stop cleaning through directional blowing and wastewater recycling.

[0032] Among them, filter element 8 refers to the particulate matter interception component installed inside the venturi tube. Specifically, it can be a staggered metal filter screen that intercepts feathers and feed dust in the airflow through multi-stage filtration.

[0033] The core innovation of this application lies in combining a Venturi tube structure with a movable mechanism and a high-pressure cleaning system. By dynamically adjusting the airflow channel shape and periodically displacing for cleaning, it actively prevents dust accumulation while maintaining efficient heat exchange. This design alters the airflow path through mechanical movement, allowing dust to settle naturally in the negative pressure area. Combined with detachable filter components, it achieves multi-stage separation, effectively solving the problem of traditional heat exchangers easily clogging in high-dust environments like livestock farms.

[0034] The working process and principle of this application are as follows: The heat exchanger for air cooling in a livestock farm includes a housing. An air outlet pipe is connected to the upper surface of the housing, and a heat exchange component is installed on the air outlet pipe. An air inlet hopper is located at the bottom of the housing, connected to the air outlet end of the livestock farm, and the air outlet pipe is connected to the air inlet end of the livestock farm. A first circulation fan is installed at the air outlet end of the air inlet hopper, and a Venturi tube is installed on the first circulation fan. A limiting component is located on the top surface of the housing to limit and press the Venturi tube; the limiting component is connected to the air inlet end of the air outlet pipe. A movable component is located at the bottom of the housing to move the Venturi tube left and right. A cleaning component is located on the right end of the upper surface of the housing to clean the Venturi tube. A filter is installed inside the Venturi tube.

[0035] During operation, the exhaust air from the farm enters the housing through the intake hopper, is accelerated by the first circulation fan, and then enters the Venturi tube. The Venturi tube's contraction-expansion structure further accelerates the airflow, while the filter intercepts particulate matter in the airflow. After passing through the Venturi tube, the airflow enters the exhaust pipe, exchanges heat with the heat exchanger, and then returns to the farm.

[0036] The venturi tube moves left and right via a movable component, altering the airflow path and preventing dust accumulation in specific locations. A limiting component restricts and presses the venturi tube, ensuring stable operation. A cleaning component periodically cleans the venturi tube, removing any adhering substances.

[0037] This design effectively solves the problems of dust clogging, corrosion and maintenance difficulties faced by traditional heat exchangers in farm applications through dynamic airflow channels, detachable filter structures and periodic cleaning mechanisms.

[0038] As a preferred embodiment, the solution of this application is specifically implemented as follows:

[0039] The heat exchanger for air cooling in the farm includes a housing made of stainless steel, which has good corrosion resistance. A cylindrical air outlet pipe is connected to the center of the upper surface of the housing, and a heat exchange element is installed on the air outlet pipe. The heat exchange element adopts a shell-and-tube structure, with multiple copper tubes inside. Cooling water flows inside the copper tubes, indirectly exchanging heat with the external hot air.

[0040] A funnel-shaped air inlet is located on the bottom left side of the chamber, and it connects to the farm's exhaust fan. The exhaust pipe connects to the farm's intake fan, forming a closed loop. A first circulation fan, an axial flow fan, is installed above the exhaust end of the air inlet to accelerate the airflow.

[0041] A venturi tube is installed above the first circulation fan. Made of wear-resistant engineering plastic, the venturi tube features a modular design for easy disassembly and cleaning. The inner wall of the venturi tube is lined with multiple layers of stainless steel mesh as a filter element for the graded interception of particulate matter.

[0042] An electric telescopic cylinder is installed on the top surface of the chamber as a limiting component. The end of the telescopic rod of the electric telescopic cylinder is connected to a lifting sleeve. The lifting sleeve is connected to the air inlet end of the air outlet pipe through a corrugated pipe to achieve a flexible seal. A second circulation fan is installed on the lower surface of the lifting sleeve to further accelerate the airflow.

[0043] A support frame is installed on the bottom right side of the housing. A synchronous motor and a screw are mounted on the support frame, and a moving block connected to the venturi tube is installed on the screw. The synchronous motor drives the screw to rotate, causing the venturi tube to move back and forth.

[0044] A cleaning pipe is installed on the right end of the upper surface of the chamber, with its end connected to a corrugated pipe and a lifting bucket. Multiple high-pressure air outlet pipes are evenly arranged on the lifting bucket and connected to an annular air inlet pipe. High-pressure gas is injected through the outlet pipes to periodically clean the venturi tube.

[0045] The bottom of the tank is equipped with an inclined baffle and a collection hopper for collecting condensate and cleaning wastewater. The collection hopper is connected to a drain pipe, and a solenoid valve is installed on the drain pipe to control the drainage.

[0046] Through the above-described solution, this application achieves efficient cooling and purification of air in livestock farms. The dynamic venturi tube structure effectively prevents dust blockage and extends the effective operating cycle of the equipment. Removable filters facilitate cleaning and replacement, reducing maintenance difficulty. The cleaning method combining high-pressure airflow and mechanical friction effectively removes deposits and accumulated water, preventing microbial growth. The overall design is adapted to the high-dust, high-humidity environment of livestock farms, improving heat exchange efficiency, reducing operating and maintenance costs, and providing a reliable solution for environmental control in livestock farms.

[0047] Please continue reading. Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the heat exchanger 3 includes a heat exchange tube 31, which is installed and fixed on the gas outlet pipe 2 via a flange 32. Multiple gas transmission copper pipes 33 are arranged at equal intervals inside the heat exchange tube 31. The gas outlet pipe 2 is connected to the gas transmission copper pipes 33. A first partition plate 34 is provided at both the left and right ends of the lower inner surface of the heat exchange tube 31. A second partition plate 35 is provided in the middle of the upper inner surface of the heat exchange tube 31. The second partition plate 35 is located between the first partition plates 34 at the left and right ends. A water inlet pipe 36 is connected to the right end of the lower surface of the heat exchange tube 31, and a water outlet pipe 37 is connected to the left end of the upper surface of the heat exchange tube 31.

[0048] The flange connects the heat exchange tubes to the outlet pipe using bolts, ensuring airtightness and facilitating disassembly and maintenance. Multiple copper air supply pipes are arranged parallel to the heat exchange tube axis, forming a multi-channel airflow path. The first partition plate is vertically welded to both sides of the bottom of the heat exchange tube, and the second partition plate is centrally welded to the top of the heat exchange tube; together, they form a meandering water flow channel. The water inlet pipe is threaded to the bottom right side of the heat exchange tube, and the water outlet pipe is flanged to the top left side of the heat exchange tube.

[0049] Specifically, the cryogenic medium enters the bottom of the heat exchange tube through the inlet pipe. After being blocked by the first partition plate, it splits into two streams, flowing to the left and right along the bottom of the heat exchange tube to the ends, then turning upwards and converging in the middle area at the top under the guidance of the second partition plate, finally exiting from the outlet pipe. During this process, the meandering water flow path prolongs the residence time of the cryogenic medium in the heat exchange tube, while multiple gas-transmitting copper pipes divide the hot air into several fine streams, increasing the gas-liquid contact area. The staggered layout of the first and second partition plates eliminates dead zones in the flow, reduces dust deposition on the tube walls, and the flange connection structure facilitates periodic disassembly and cleaning of the inside of the gas-transmitting copper pipes.

[0050] As a preferred embodiment, the solution of this application is specifically implemented as follows:

[0051] The heat exchanger includes heat exchange tubes. The heat exchange tubes are mounted and fixed to the outlet pipe via flanges. Multiple copper gas-carrying pipes are evenly spaced inside the heat exchange tubes. The outlet pipe is connected to the copper gas-carrying pipes. First partition plates are installed at both ends of the lower inner surface of the heat exchange tubes. A second partition plate is installed in the middle of the upper inner surface of the heat exchange tubes, located between the first partition plates at the left and right ends. A water inlet pipe is connected to the right end of the lower inner surface of the heat exchange tubes. A water outlet pipe is connected to the left end of the upper inner surface of the heat exchange tubes.

[0052] Specifically, the heat exchange tubes can be made of stainless steel, with a diameter of 300mm and a length of 1000mm. There can be 20 copper gas pipes, each with a diameter of 10mm. Both the first and second partition plates are made of 2mm thick stainless steel. The inlet and outlet water pipes are both 50mm in diameter. The flanges are standard DN300 flanges.

[0053] Through the above technical solution, this application achieves highly efficient heat exchange between air and water. Multiple copper air pipes increase the heat exchange area and improve heat exchange efficiency. The partition plate creates a serpentine water flow channel, extending the water flow path and further enhancing heat exchange. Simultaneously, using copper pipes as air channels provides excellent thermal conductivity, allowing for rapid heat transfer to the external water flow. Furthermore, the flange connection facilitates disassembly and cleaning, which is beneficial for equipment maintenance.

[0054] Please continue reading. Figure 1 and Figure 2As shown, in one embodiment of the present invention, the limiting member 5 includes a first electric telescopic cylinder 51. The first electric telescopic cylinder 51 is provided at both the left and right ends of the upper surface of the housing 1. The air inlet end of the air outlet pipe 2 is connected to a first corrugated pipe 52. A lifting sleeve 53 is provided at the end of the first corrugated pipe 52. A second circulation fan 54 corresponding to the venturi tube 4 is provided on the lower surface of the lifting sleeve 53. The telescopic rod end of the first electric telescopic cylinder 51 is connected to the lifting sleeve 53.

[0055] The first electric telescopic cylinder is symmetrically distributed on both sides of the center of the top surface of the housing, driving the vertical movement of the lifting sleeve through the synchronous extension and retraction of the telescopic rod. The first bellows is made of flexible metal, with its two ends connected to the air inlet of the outlet pipe and the flange of the lifting sleeve, respectively, allowing the lifting sleeve to maintain airtightness during vertical displacement. The second circulation fan, located on the lower surface of the lifting sleeve, is coaxially arranged with the Venturi tube, and the fan blade diameter matches the inlet size of the Venturi tube. The support block is made of aluminum alloy, with a rubber buffer pad on its surface, and is rigidly connected to the bottom surface of the lifting sleeve.

[0056] Specifically, when the relative position of the venturi tube and the air inlet needs to be adjusted, the first electric telescopic cylinder pushes the lifting sleeve vertically via the telescopic rod, causing the second circulating fan and the venturi tube to rise and fall synchronously. The first bellows undergoes elastic deformation during the rising and falling process to compensate for the displacement of the lifting sleeve and maintain the continuity of the airflow path. The second circulating fan operates continuously during the rising and falling process to ensure a stable airflow velocity as it passes through the venturi tube. The vertical displacement range of the lifting sleeve is 50-80 mm, with a displacement accuracy controlled within ±1 mm. Adjusting the lifting height optimizes the flow velocity at the throat of the venturi tube, improving heat exchange efficiency. In cleaning mode, the lifting sleeve is raised to its highest position, aligning the venturi tube with the high-pressure airflow jet path of the cleaning component, facilitating the thorough removal of adhering dust.

[0057] As a preferred embodiment, the solution of this application is specifically implemented as follows:

[0058] The limiting component includes a first electric telescopic cylinder. A first electric telescopic cylinder is installed at both ends of the upper surface of the housing. The air inlet end of the outlet pipe is connected to a first corrugated pipe. A lifting sleeve is installed at the end of the first corrugated pipe. A second circulation fan corresponding to a venturi tube is installed on the lower surface of the lifting sleeve. The end of the telescopic rod of the first electric telescopic cylinder is connected to the lifting sleeve.

[0059] Specifically, the first electric telescopic cylinder adopts a servo motor-driven lead screw structure, which has high-precision position control capability. The first bellows is made of high-temperature and corrosion-resistant rubber material, which can adapt to frequent telescopic movements. The lifting sleeve is made of lightweight aluminum alloy material, and the inner wall is coated with an anti-corrosion coating. The second circulating fan is an axial flow fan, and the blades adopt an aerodynamically optimized design to improve airflow uniformity.

[0060] Through the above technical solution, this application achieves precise positioning and compression of the venturi tube, improving airflow efficiency. Simultaneously, the addition of a second circulating fan enhances airflow turbulence, further improving heat exchange efficiency. Furthermore, the use of corrugated pipes increases system flexibility, reduces mechanical wear, and extends equipment lifespan. The overall structural design is simple, easy to install and maintain, and suitable for the harsh environments of farms.

[0061] Please continue reading. Figure 3 and Figure 4 As shown, in one embodiment of the present invention, sealing rings 41 are provided on both the upper and lower surfaces of the venturi tube 4.

[0062] The sealing ring covers the upper surface of the venturi tube where it contacts the limiting component and the bottom surface where it connects to the moving component. The ring is made of a corrosion-resistant elastic material, such as EPDM rubber or silicone, with a thickness ranging from 2 to 5 mm. The ring is fixed to the tube surface by means of grooves or adhesive bonding, with the groove depth being one-third to one-half the thickness of the ring. When the moving component drives the venturi tube to move laterally, the sealing ring deforms under pressure, filling the assembly gap between the tube body and the limiting and moving components, preventing external air or dust from entering the tube body through the contact surface.

[0063] Specifically, when the first electric telescopic cylinder drives the lifting sleeve to press down, the second circulating fan tightly contacts the sealing ring on the upper surface of the venturi tube, preventing airflow from escaping from the contact surface. Simultaneously, the moving component drives the venturi tube to move left and right via a screw, maintaining a dynamic seal between the bottom sealing ring and the support frame, preventing dust from entering the tube body. The elastic deformation of the sealing ring compensates for changes in clearance caused by component assembly tolerances and vibration, ensuring the venturi tube's sealing performance in both moving and stationary states. Therefore, the sealing ring effectively reduces airflow loss and dust intrusion, extends the filter cleaning cycle, and reduces maintenance frequency.

[0064] As a preferred embodiment, the solution of this application is implemented as follows: Sealing rings are provided on both the upper and lower surfaces of the venturi tube. The sealing rings are made of high-temperature resistant and corrosion-resistant silicone material and have a ring-shaped structure. The inner diameter of the sealing ring matches the outer diameter of the venturi tube, allowing it to fit tightly against the surface of the venturi tube. The cross-section of the sealing ring is circular, with a diameter of 5-10 mm. During installation, the sealing ring is compressed and deformed, forming a sealing contact with adjacent components.

[0065] Through the above technical solution, this application achieves an airtight connection between the Venturi tube and adjacent components, preventing air leakage. The sealing ring improves the sealing performance of the entire system, ensuring directional airflow within the Venturi tube and preventing a reduction in cooling efficiency. Simultaneously, the use of the sealing ring simplifies the installation process, facilitating the disassembly and maintenance of the Venturi tube.

[0066] Please continue reading. Figure 2 and Figure 4 As shown, in one embodiment of the present invention, the Venturi tube 4 includes a first arc-shaped tube 42 and a second arc-shaped tube 43. The first arc-shaped tube 42 has a first connecting block 44 at both ends of its two ends, and a first threaded hole 45 on the first connecting block 44. The second arc-shaped tube 43 has a second connecting block 46 at both ends of its two ends, corresponding to the first connecting block 44. The second connecting block 46 has a second threaded hole 47 corresponding to the first threaded hole 45. A sealing strip (not shown) is provided at the connection between the first arc-shaped tube 42 and the second arc-shaped tube 43.

[0067] The first and second arc-shaped tubes are designed to be detachably connected. The first and second connecting blocks are fixed together by threaded holes, and a sealing strip is embedded in the gap at the connection to enhance airtightness. The split structure allows the arc-shaped tubes to be removed separately without disassembling the overall Venturi tube, facilitating cleaning or replacement of the internal filter components. The threaded connection provides stable fixing force, preventing vibration from causing the connection to loosen. The sealing strip is made of corrosion-resistant elastic material, which can adapt to the deformation compensation requirements in high humidity environments.

[0068] Specifically, when filter maintenance is required, operators can loosen the bolts between the first and second threaded holes to separate the first and second arc-shaped tubes, directly contacting the internally staggered first and second filter plates for cleaning or replacement. The sealing strip deforms under pressure when the arc-shaped tubes are closed, filling the tiny gaps between the connecting surfaces and preventing gas leakage from the joints. The split structure combined with the threaded fixing method further reduces the risk of component wear due to frequent disassembly and assembly during maintenance, extending the overall service life of the venturi tube.

[0069] As a preferred embodiment, the solution of this application is specifically implemented as follows:

[0070] The venturi tube includes a first arc-shaped tube and a second arc-shaped tube. First connecting blocks are provided at the top and bottom ends of both ends of the first arc-shaped tube, and each first connecting block has a first threaded hole. Second connecting blocks, corresponding to the first connecting blocks, are provided at the top and bottom ends of both ends of the second arc-shaped tube, and each second connecting block has a second threaded hole corresponding to the first threaded hole. A sealing strip is provided at the connection between the first and second arc-shaped tubes.

[0071] Specifically, both the first and second arc-shaped tubes are made of stainless steel, with an inner diameter of 300mm. Both the first and second connecting blocks are rectangular blocks, 50mm long, 30mm wide, and 10mm thick. The diameter of both the first and second threaded holes is 8mm. The sealing strip is made of high-temperature resistant rubber with a thickness of 2mm.

[0072] Furthermore, the first and second arc-shaped tubes are connected by bolts. The bolts pass through the first and second threaded holes, fastening the first and second connecting blocks together. A sealing strip is placed between the connecting surfaces of the first and second arc-shaped tubes and is tightened by the bolts to form a sealing structure.

[0073] Through the above technical solution, this application achieves a detachable structural design for the Venturi tube. This allows for easy disassembly and assembly, facilitating cleaning and maintenance. Furthermore, the sealing strip ensures the airtightness of the Venturi tube during use, preventing air leakage. In addition, the use of stainless steel to construct the arc-shaped tube provides excellent corrosion resistance and strength, making it suitable for the harsh environments of farms. This design not only extends the service life of the Venturi tube but also reduces maintenance costs, while ensuring the efficient operation of the air cooling system.

A plurality of first U-shaped mounting blocks 83 are equally spaced on the inner side of the first arc-shaped tube 42. The first filter plate 81 is fixedly mounted in the first U-shaped mounting block 83 by a first bolt. A plurality of second U-shaped mounting blocks 84 are equally spaced on the inner side of the second arc-shaped tube 43. The second filter plate 82 is fixedly mounted in the second U-shaped mounting block 84 by a second bolt. The first filter plate 81 and the second filter plate 82 are arranged alternately.

[0075] The first and second U-shaped mounting blocks are welded to the inner walls of the first and second arc-shaped tubes, respectively, with the openings of the mounting blocks facing the center of the tube axis. The first and second bolts are made of stainless steel, with their threads passing through pre-drilled holes in the sidewalls of the U-shaped mounting blocks to mate with fixing holes on the edge of the filter plates. The first and second filter plates are made of perforated metal plates with hole diameters of 0.5-1.2 mm and plate thicknesses of 0.8-1.5 mm. The staggered arrangement involves adjacent filter plates forming a 30-45 degree angle, with the holes on the upper and lower filter plates arranged in a staggered manner.

[0076] Specifically, when dust-laden airflow passes through the venturi tube, the double-layered staggered filtration structure composed of the first and second filter plates forms a multi-stage interception. The airflow first contacts the first filter plate, where larger particles are trapped on the windward side. Smaller particles, carried by the airflow through the holes of the first filter plate, change their flow direction due to the staggered arrangement of the second filter plates, causing uninterrupted fine particles to collide with the surface of the second filter plates. The filter plates are secured by U-shaped mounting blocks and bolts, allowing for individual removal of any filter plate for cleaning or replacement during maintenance, without the need to dismantle the entire filtration structure. During disassembly, a tool is inserted into the venturi tube, and the first bolt is loosened to remove the first filter plate from the U-shaped mounting block groove. The second bolt is used similarly to remove the second filter plate. The staggered arrangement of the filter plates maintains the effective cross-sectional area of ​​the airflow channel while dispersing the dust trapping area across multiple filtration stages, avoiding the concentrated clogging problem of single-layer filtration structures.

[0077] As a preferred embodiment, the solution of this application is specifically implemented as follows:

[0078] The filter element includes a first filter plate and a second filter plate. Multiple first U-shaped mounting blocks are evenly spaced on the inner side of the first arc-shaped tube. The first filter plate is fixed within each first U-shaped mounting block by first bolts. Multiple second U-shaped mounting blocks are evenly spaced on the inner side of the second arc-shaped tube. The second filter plate is fixed within each second U-shaped mounting block by second bolts. The first and second filter plates are arranged alternately.

[0079] Specifically, the first and second filter plates are made of stainless steel, which is corrosion-resistant. Both filter plates have a microporous structure with a pore size of 0.5-1mm on their surfaces. The first and second U-shaped mounting blocks are made of high-strength engineering plastic, providing insulation between them and the metal arc-shaped tube. The first and second bolts are anti-loosening bolts to ensure secure installation of the filter plates. The first and second filter plates are staggered at a spacing of 10-20mm, forming a labyrinthine filtration structure.

[0080] Through the above technical solution, this application achieves high-efficiency filtration inside the venturi tube. The first and second filter plates are staggered to form a labyrinthine structure, increasing the filtration area and improving filtration efficiency. The detachable installation method facilitates regular cleaning and replacement of the filter plates, reducing maintenance difficulty. The stainless steel filter plates have excellent corrosion resistance, extending their service life. The microporous structure effectively blocks dust particles from entering the system, protecting downstream equipment. The overall structure is simple and compact, easy to install, and suitable for harsh environments in livestock farms.

Figure 2 and Figure 3As shown, in one embodiment of the present invention, the movable component 6 includes a support frame 61, which is disposed at the right end of the bottom surface of the housing 1. A support plate 62 is disposed at the right end of the upper surface of the support frame 61. Support blocks 63 are disposed on both the front and rear sides of the left end of the upper surface of the support frame 61. A synchronous motor 64 is disposed at both the front and rear ends of the right side of the support plate 62. A screw 65 is connected to the output end of the synchronous motor 64. The end of the screw 65 is connected to the support block 63. A movable block 66 is spirally sleeved on the screw 65. A connecting block 67 is disposed at the lower end of the front and rear surfaces of the venturi tube 4. The lower surfaces of the connecting block 67 and the movable block 66 are connected by a return spring (not shown).

[0082] The support frame 61 is constructed of channel steel welded to the bottom of the housing. The support plate is 8-12mm thick and welded perpendicularly to the support frame. The output shaft of the synchronous motor 64 is coaxially connected to the screw via a coupling. The screw has a diameter of 20-25mm and a lead of 5-8mm. A copper threaded sleeve is embedded inside the moving block, forming a helical pair with the screw. The connecting block is made of L-shaped steel plate welded to the outer wall of the venturi tube. The return spring has an elastic coefficient of 15-20N / mm and a free length of 80-100mm. A self-lubricating bearing seat is provided on the top of the support block to support the end of the screw.

[0083] Specifically, after the synchronous motor starts, it drives the screw to rotate, causing the moving block to move horizontally along the screw axis. The moving block pulls the connecting block through a return spring, allowing the venturi tube to slide laterally within the housing. When the displacement of the moving block reaches a set value, the return spring undergoes elastic deformation to buffer inertial impact. The support block and support plate form a double-point support structure, ensuring that the coaxiality error of the screw during rotation is less than 0.1mm. The clearance between the copper threaded sleeve and the screw is controlled within the range of 0.05-0.1mm, ensuring both transmission accuracy and reducing friction loss. The maximum deformation of the return spring during its compression stroke does not exceed 30% of its free length, preventing plastic deformation. The channel steel structure of the support frame has a deflection of less than 1mm when subjected to a 200kg dynamic load, ensuring the straightness of the movement trajectory.

[0084] As a preferred embodiment, the solution of this application is specifically implemented as follows:

[0085] The moving component includes a support frame, which is located at the right end of the bottom surface of the housing. A support plate is mounted on the right end of the upper surface of the support frame, and support blocks are mounted on the front and rear sides of the left end of the upper surface of the support frame. Synchronous motors are mounted on the front and rear ends of the right side of the support plate, and the output ends of the synchronous motors are connected to screws. The ends of the screws are connected to the support blocks. Moving blocks are helically sleeved on the screws, and connecting blocks are mounted on the lower ends of the front and rear surfaces of the venturi tube. The connecting blocks and the lower surfaces of the moving blocks are connected by a return spring.

[0086] Specifically, the support frame can be made of stainless steel to improve corrosion resistance. The support plate and support block can be made of aluminum alloy to reduce weight. A servo motor is selected for the synchronous motor, providing precise control. The screw adopts a ball screw structure, enabling smooth and precise linear motion. The moving block is made of copper alloy, ensuring a good fit with the screw. The return spring is made of stainless steel, offering good elasticity and corrosion resistance.

[0087] Through the above technical solution, this application achieves automated left-right movement of the venturi tube. This allows for adjustment of the venturi tube's position as needed, optimizing airflow distribution and improving heat exchange efficiency. Simultaneously, the moving mechanism is simple, reliable, and easy to maintain, making it suitable for long-term use in harsh environments such as farms. Furthermore, the return spring cushions the movement of the venturi tube, preventing sudden position changes from interfering with airflow and ensuring the stability of the air cooling process.

[0088] Please continue reading. Figure 2 and Figure 5 As shown, in one embodiment of the present invention, the cleaning component 7 includes a second electric telescopic cylinder 71. A cleaning pipe 72 is embedded at the right end of the upper surface of the housing 1. The end of the cleaning pipe 72 is connected to a second corrugated pipe 73. The right and left sides of the upper surface of the housing 1 are provided with second electric telescopic cylinders 71. The telescopic rod end of the second electric telescopic cylinder 71 is provided with a lifting bucket 74. The lifting bucket 74 is connected to the second corrugated pipe 73. Multiple high-pressure air outlet pipes 75 are embedded at equal intervals on the lifting bucket 74. The multiple high-pressure air outlet pipes 75 are all connected through an annular air inlet pipe 76. A collection bucket 77 is provided at the right end of the lower surface of the support frame 61. The collection bucket 77 is connected to a drain pipe 78. A solenoid valve 79 is provided inside the drain pipe 78.

[0089] The second electric telescopic cylinder is configured to drive the lifting bucket to move vertically, so that the high-pressure air outlet pipe is aligned with the surface of the venturi tube; the high-pressure air outlet pipe is connected to an external air source or water source through an annular air inlet pipe to form a high-pressure jet stream; the second corrugated pipe allows the lifting bucket to maintain communication with the cleaning pipe during movement; the collection bucket is arranged below the support frame to collect the sewage generated during the cleaning process; the solenoid valve in the drain pipe can remotely control the start and stop of sewage discharge.

[0090] Specifically, when cleaning the venturi tube is required, the second electric telescopic cylinder pushes the lifting bucket down to a predetermined height, and the high-pressure air outlet pipe sprays high-pressure media onto the surface of the venturi tube. The wastewater generated by the spraying is collected in the collection bucket and discharged centrally through the drain pipe. The solenoid valve automatically opens to drain the water based on the liquid level signal in the collection bucket, preventing wastewater retention. The second corrugated pipe undergoes elastic deformation as the lifting bucket moves, ensuring continuous delivery of the cleaning media and compensating for differences in lifting displacement. Multiple high-pressure air outlet pipes are arranged in a linear array, equidistantly to maximize the cleaning coverage area. This solution achieves in-situ cleaning through integrated cleaning components, eliminating the need to disassemble equipment parts and allowing maintenance operations to be performed during operation.

[0091] As a preferred embodiment, the solution of this application is implemented as follows: A cleaning pipe embedded at the right end of the upper surface of the housing is connected to a flexible second corrugated pipe, the end of which extends to the right end of the inner top surface of the housing. Two electric telescopic cylinders are symmetrically arranged on the left and right sides of the right end of the inner top surface of the housing, with funnel-shaped lifting buckets fixedly connected to the ends of their telescopic rods. The bottom of the lifting buckets forms a sealed connection with the end of the second corrugated pipes. Six high-pressure air outlet pipes are arranged in a ring at the top of the inner cavity of the lifting buckets, radially distributed and connected to an annular air inlet pipe, which is connected to a high-pressure air pump. A conical collection bucket is inclinedly arranged at the right end of the lower surface of the support frame, with a drain pipe connected to the bottom of the collection bucket. A solenoid valve is installed in the middle of the drain pipe to control drainage.

[0092] Through the above technical solution, this application realizes the automated cleaning of dust accumulation on the surface of Venturi tubes. High-pressure airflow forms a three-dimensional scouring effect through an adjustable-angle air outlet pipe, effectively removing particulate matter attached to the tube wall. The lifting bucket is height-adjusted by the extension and retraction of the electric cylinder, so that the airflow spray range covers different sections of the Venturi tube. The collection bucket and the drain pipe form a closed drainage channel to prevent sewage generated during the cleaning process from dripping into the aquaculture environment. The entire cleaning process does not require disassembly of equipment parts, significantly reducing the impact of maintenance operations on aquaculture production.

[0093] The second electric telescopic cylinder drives the lifting bucket to move vertically, adjusting the relative position between the high-pressure air outlet pipe and the venturi pipe; the second corrugated pipe allows the lifting bucket to maintain communication with the cleaning pipe during movement; the annular air inlet pipe evenly distributes external high-pressure gas to each high-pressure air outlet pipe; the collection bucket is located directly below the venturi pipe and is used to collect the sewage generated during the cleaning process; the solenoid valve controls the opening and closing of the drain pipe to achieve timed sewage discharge.

[0094] Specifically, when cleaning the Venturi tubes is required, the second electric telescopic cylinder pushes the lifting bucket down to a preset height, aligning the high-pressure air outlet with the Venturi tube surface. High-pressure gas enters each high-pressure air outlet through the annular air inlet pipe, forming multiple concentrated airflows that impact the Venturi tube surface, stripping away adhering dust. Wastewater and detached materials generated during the cleaning process fall directly into the collection hopper, preventing dripping into other areas of the chamber. The solenoid valve periodically opens the drain pipe according to a preset program, discharging the wastewater from the chamber. Through the vertical movement of the lifting bucket and the directional spraying of high-pressure airflow, the cleaning of the Venturi tube surface is automated. Simultaneously, the coordination of the collection hopper and drain pipe solves the problem of wastewater retention, reducing manual intervention.

[0095] Please continue reading. Figure 1 and Figure 2 As shown, in one embodiment of the present invention, a vibration motor 9 is provided on the side of the venturi tube 4, and an openable door 10 is provided on the right side of the front of the housing 1.

[0096] The vibration motor 9 is bolted to the middle of the side wall of the venturi tube, with its output shaft perpendicular to the axis of the venturi tube. The vibration frequency is adjustable from 20-50Hz. The hinged door 10 is installed on the right side of the front of the enclosure, with a rubber sealing strip along the edge of the door frame and a transparent observation window embedded in the center. The vibration motor and the screw drive mechanism of the moving parts are linked via a control module. When the moving block drives the venturi tube to the rightmost position, the vibration motor automatically starts.

[0097] Specifically, the high-frequency mechanical vibration generated by the vibrating motor is transmitted to the wall of the venturi tube, causing dust particles adhering to the filter plate surface to detach. This vibration, combined with the left-right reciprocating motion driven by the moving parts, forms a three-dimensional vibration cleaning mode, with a horizontal travel of 200mm and a vibration amplitude controlled within the range of 3-5mm. The openable door can open to an angle of up to 90 degrees during maintenance operations, allowing operators to directly access the venturi tube for deep cleaning or filter replacement. Dust detached during the vibration cleaning process is collected in the collection hopper and discharged from the system through the drain pipe, while the solenoid valve remains open. This solution achieves online cleaning, avoiding equipment downtime required by traditional maintenance methods, while the transparent observation window facilitates real-time monitoring of the internal cleaning status.

[0098] As a preferred embodiment, the solution of this application is specifically implemented as follows: a vibration motor is installed on the outer side of the side wall of the venturi tube, and its output shaft is rigidly connected to the outer wall of the venturi tube. The housing of the vibration motor is fixed to the support frame inside the box by bolts. A rectangular opening is provided at the right end of the front of the box, and a door frame is welded to the edge of the opening. The door frame and the openable door are connected by a hinge. A sealing strip is embedded on the inner side of the door frame. When the openable door is closed, it forms an airtight contact with the door frame. A rotating handle and a locking device are provided on the outer side of the door panel.

[0099] Through the above technical solution, this application uses the periodic high-frequency vibration generated by the vibration motor to remove dust particles attached to the inner wall of the venturi tube and the surface of the filter element, effectively avoiding flow channel blockage caused by dust caking; the design of the openable door allows direct contact with the venturi tube assembly without disassembling the box structure during maintenance operations, significantly shortening equipment maintenance time, while the sealed structure ensures that the airtightness of the equipment during operation is not affected by the maintenance channel.

[0100] The vibration motor, electric telescopic cylinder, circulating fan, solenoid valve and synchronous motor in this invention are all existing technologies, which are already clearly understood by those skilled in the art, and will not be described in detail here.

[0101] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be included in the scope of the present invention.
