Description

Technical Field

[0001] This invention relates to the field of air conditioning and purification technology for animal housing, specifically an SPF-grade air conditioning and purification system for animal housing. Background Technology

[0002] SPF-grade animal facilities are an important support platform for biomedical research. Their core function is to maintain the cleanliness, temperature, humidity, pressure difference, and air exchange rate of the indoor environment through air conditioning and purification systems, so as to ensure animal health and the reliability of experimental results. However, clean airflow is supplied from the top of the room and returned from the bottom, which can easily create dead air zones or eddies around the cages, causing pollutants to accumulate. The air in different cages and different areas of the room can easily mix with each other. If pollution occurs at a certain point, it can easily spread to the whole room. In order to maintain the cleanliness of the entire large space, a high number of air exchanges is required, and the continuous exchange of cold and hot air increases the energy consumption of the fans. Summary of the Invention

[0003] The purpose of this invention is to provide an SPF-grade animal facility air conditioning and purification system to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An SPF-grade animal housing air conditioning and purification system includes an animal housing component for use in animal housing areas. An air supply assembly is used to draw in outside air and deliver it into the animal house. The air supply assembly is installed on top of the animal breeding assembly. The air supply assembly includes an air supply box, one end of which is provided with an exhaust pipe and a pre-filter inside the exhaust pipe. The other end of the air supply box is provided with an air supply pipe. A heat exchange assembly is used to exchange heat between the exhaust air and the extracted air. The heat exchange assembly is installed on the top of the animal breeding assembly and is connected to one side of the air supply assembly. The heat exchange assembly includes a heat exchange box, with an air inlet pipe and an air guide pipe connected to the two ends of the heat exchange box respectively. An exhaust pipe and a discharge pipe that communicate with the heat exchange jacket inside the heat exchange box are respectively connected to the side wall of the heat exchange box. The control component is used to perform intermediate filtration processing on the air after heat exchange. The control component is installed inside the animal room and is connected to the end of the air duct on the heat exchange component. The control component includes a control box, and the control box is equipped with a partition. The left compartment of the partition is equipped with a medium-efficiency filter for preheating or precooling the air after heat exchange, and the right compartment of the partition is equipped with a medium-efficiency filter. An exhaust system is used to guide pre-treated air from the top of the animal house for discharge. The exhaust system is installed in the animal house and is connected to the end of the control system. The exhaust system includes an exhaust box with a high-efficiency filter in the middle and an air outlet for adjusting the air direction on the exhaust box. The cage assembly is used for fixed-point animal breeding and air purification. The cage assembly is installed inside the animal room and is connected to the exhaust pipe on the heat exchange assembly. The cage assembly includes several feeding boxes. A filter box and a purification box are arranged sequentially on the right side of each feeding box. A blower assembly is provided on one side of each feeding box and is connected to the filter box through a check valve. The filter box and the purification box are internally connected. A return air pipe is provided on one side of the purification box and is connected to the exhaust pipe.

[0005] Secondly, the animal house is made of color steel sandwich panels and has a movable sealed door on one side.

[0006] In this invention, color steel sandwich panels serve as the six walls of the animal house, increasing the overall insulation effect and reducing the impact of stable changes in the external environment on large internal temperature differences, thus reducing energy consumption. The sealed door facilitates the entry and exit of operators, and the closure of the sealed door helps to increase the internal airtightness and reduce the impact of air leakage caused by gaps.

[0007] Furthermore, the air supply box is fixed to the top of the animal room with bolts, the exhaust pipe and the air supply box are integrally formed, the bottom inner wall of the exhaust pipe is provided with a limiting ring, a non-woven cotton cloth is provided below the limiting ring, and a protective net for protecting the exhaust pipe port is provided below the non-woven cotton cloth.

[0008] In this invention, the limiting ring is fixed to the exhaust pipe by bolts, and the bottom of the protective net is inserted into the limiting groove on the side wall of the exhaust pipe by corresponding clips and fixed by corresponding bolts. The limiting ring and the protective net fix the position of the non-woven cotton cloth. The protective net initially intercepts the air entering the exhaust pipe from the outside, filters large particles and insects, and with the cooperation of the non-woven cotton cloth, achieves primary filtration, intercepting dust and particulate matter in the air.

[0009] Specifically, the air supply pipe and the air supply box are fixed with bolts, the end of the air supply pipe and the end of the air inlet pipe are fixed with bolts, a motor is provided on one side of the outer wall of the air supply box, the output shaft of the motor is connected to a fan wheel through a coupling, and the fan wheel extends into the interior of the air supply box.

[0010] In this invention, the motor is electrically connected to an external power source via a wire, and the control switch on the outer wall is electrically connected to the processor inside the display screen on the outer wall of the control box via a wire. The processor controls the motor to start, thereby rotating the impeller and guiding the air from the outer port of the air supply duct to be continuously drawn into the air inlet duct, thus replacing the air inside the animal room and facilitating continuous ventilation.

[0011] It should be noted that the heat exchange box has a guide hole at the end that penetrates the heat exchange jacket. The guide holes are distributed in a ring at equal intervals. The two ends of the guide holes are respectively connected to the air inlet pipe and the air guide pipe. The heat exchange jacket is provided with spiral blades. The exhaust pipe is connected to the bottom of the heat exchange jacket and the discharge pipe is connected to the top of the heat exchange jacket.

[0012] In this invention, the guide hole facilitates the passage of air entering through the air inlet duct and into the air duct itself. The spiral blade and the heat exchange box are integrally formed, and the guide hole penetrates the spiral blade. The spiral blade divides the interior of the heat exchange jacket into a spiral shape, extending the exhaust duct. The air drawn from the animal room spirals upward in the heat exchange box, increasing the path through the heat exchange box and facilitating the enclosure and fit of the guide hole. The air discharged from the exhaust duct preheats or precools the air entering through the guide hole. When the air inside the animal room is hot, the discharged hot air preheats the initially entering air, reducing heating and increasing energy consumption. When the air inside the animal room is cold, the discharged cold air precools the initially entering air, reducing cooling and increasing energy consumption.

[0013] Furthermore, the control box is connected to the bottom of the inner wall of the animal room by bolts. The partition plate and the control box are integrally formed. A surface cooler and a heater are arranged in sequence in the compartment on the left side of the partition plate. The bottom of the surface cooler is fixed to the control box by bolts. The heater is fixed to the control box by bolts. The air inlet port on the left end of the surface cooler is connected to the end of the air duct. The exhaust port on the right end of the surface cooler is connected to the bottom air inlet on the left end of the heater. The top exhaust port on the right end of the heater is connected to the compartment on the right side of the partition plate through a pipe. In this invention, a display screen is provided on the outer wall of the control box to display the overall working status. The display screen is equipped with a processor, which controls the air supply box to continuously supply air and controls the corresponding start of the surface cooler and heater. The surface cooler cools the air entering the interior from the air duct, and the heater preheats the air entering the interior. The surface cooler and heater are controlled independently, and only one can be started at a time. A temperature sensor is provided at the end connection port of the heater to detect the temperature of the initially entering air. The temperature of the initially entering air can be viewed in real time through the display screen. The surface cooler cools and dehumidifies the air by absorbing heat through refrigerant evaporation or by exchanging sensible heat with chilled water. The heater transfers heat to the air through a heat medium, raising the air temperature. When hot air needs to be introduced into the animal room for heating, the surface cooler stops operating. The heater, receiving a feedback signal from the processor, activates its control switch to heat the air entering through the duct. A temperature sensor monitors the heated air in real time. Once a set threshold is reached, the heater stops heating, maintaining the current temperature for the air passing through. When cold air needs to be introduced into the animal room for cooling, the heater stops operating. The surface cooler, receiving a feedback signal from the processor, activates its control switch to cool the air entering through the duct. A temperature sensor monitors the cooled air in real time. Once a set threshold is reached, the surface cooler stops cooling, maintaining the current temperature for the air passing through.

[0014] Secondly, a through slot is provided on the top of the control box at the right side of the partition plate. Medium-efficiency filters are symmetrically arranged in the compartment near the right side of the partition plate inside the control box. The medium-efficiency filters are made of fiber membrane cloth. A first top cover is provided at the top opening on the left side of the partition plate. A second top cover is provided in the through slot. A connecting pipe communicating with the interior is provided at the top right end of the control box. The top of the connecting pipe extends into the exhaust box.

[0015] In this invention, a partition plate divides the inside of the control box into two compartments. The left compartment pre-treats the incoming air, while the right compartment performs medium-efficiency interception filtration on the pre-treated air. The fiber membrane cloth is tightly inserted into the right compartment. The first top cover is fixed to the top left side of the control box with bolts. The bottom of the second top cover is equipped with a rubber pad, which is inserted into the through groove and fixed. The second top cover is fixed to the top right side of the control box with bolts. With the cooperation of the connecting pipe, the medium-efficiency filtered air is delivered to the exhaust box.

[0016] Specifically, a slot is provided in the middle of the lower surface of the exhaust box, a sealing bottom cover is provided in the slot, a connecting groove is provided in the middle of the sealing bottom cover, and absorbent cotton is provided in the connecting groove. An air regulating port communicating with the interior is provided near the right end of the lower surface of the exhaust box, and a louver for rotating and adjusting the direction is provided in the air regulating port.

[0017] In this invention, the sealing bottom cover is inserted into the corresponding slot, and a rubber gasket is provided on the sealing bottom cover to increase the sealing performance of the insertion between the sealing bottom cover and the slot. The sealing bottom cover is fixed to the exhaust box by bolts. The absorbent cotton is inserted into the connecting slot. The air entering the exhaust box from the connecting pipe is filtered three times by the absorbent cotton to reduce the discharge of small particles into the animal room. The absorbent cotton is made of polytetrafluoroethylene material, which fully absorbs and filters the passing air. The louvers are evenly spaced, and the louvers are rotatably connected to the air adjustment port through a rotating shaft. The direction can be manually adjusted according to the direction of exhaust required.

[0018] It is worth noting that the feeding boxes are evenly spaced, and each feeding box has a feeding chamber on its top. Each feeding chamber contains a feeding cage, and each feeding cage has a connecting hopper at its right end. The connecting hopper has a round pipe at its right end, and the inner wall of the round pipe has a blower assembly, which includes a blower tube. Each blower tube contains a fan, and the end of the round pipe has a positioning ring. The positioning ring is fixed to the outer end of the check valve by bolts.

[0019] In this invention, the feeding boxes are independently separated, and the feeding cages are easy to remove and replace, enabling independent animal breeding without interference. A screen is installed at the junction of the connecting bucket and the feeding box to prevent animal hair from entering. The fan is fixed to the blower with bolts and electrically connected to the processor on the display screen on the outer wall of the control box via wires. Each fan is individually controlled and activated, promptly extracting and expelling air from its corresponding feeding box. The positioning ring helps to ensure a tight fit and fixation with the check valve. The exhaust box draws air in from the top left side of the animal room and extracts air from the bottom right side of the animal room at the connecting bucket, achieving unidirectional airflow from left to right within the animal room. This avoids dead air zones, reduces the risk of delayed air exchange, and minimizes the spread of polluted air that could affect animals in other feeding boxes, thus reducing the risk of cross-infection.

[0020] Furthermore, the inner end of the check valve is fixed to the filter box with bolts, the filter box is provided with a filter chamber, the bottom of the side wall of the filter chamber is provided with a connecting groove that communicates with the inside of the purification box, the filter chamber is provided with filter cotton, and the top of the filter box is provided with a third top cover.

[0021] In this invention, the check valve guides air out in one direction to avoid the backflow of air inside the filter box. With the cooperation of the connecting groove, the inside of the filter box and the inside of the purification box are connected. The filter cotton filters the air initially drawn from the breeding cage to reduce the discharge of particulate matter. The lower surface of the third top cover is provided with a rubber pad to increase the sealing between the third top cover and the filter box. The third top cover is fixed to the filter box by bolts. The bolts can be removed to facilitate the opening of the third top cover to remove and replace the internal filter cotton.

[0022] In addition, the purification box has a purification chamber inside, and the purification chamber has symmetrical baffles. The baffles and the purification box are integrally formed. The left baffle has a ventilation slot near the top, and the right baffle has a ventilation slot near the bottom. Activated carbon cotton is provided on both sides of the baffles. The top of the purification box has a fourth top cover. The return air duct is connected to the inside of the purification chamber. The top of the return air duct is fixed to the bottom of the exhaust air duct with bolts.

[0023] In this invention, the baffles divide the purification chamber into multiple compartments, and the corresponding ventilation slots connect the compartments to each other, increasing the airflow path from the left compartment to the right compartment. Multiple activated carbon cotton particles further adsorb and filter the air filtered from the filter box, reducing the impact of pollutant discharge on the surrounding environment. The return air duct and exhaust air duct work together to guide the air discharged from the animal room into the heat exchange jacket in the heat exchange box. The exhaust air pre-treats the incoming air, reducing the energy consumption for heating or cooling. The corresponding air inlet duct, air guide duct, exhaust duct, and discharge duct are all covered with insulation cotton to reduce the impact of external temperature changes on the temperature of the passing air.

[0024] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, with the assistance of a motor, uses a blower to accelerate the intake of outside air, drawing it into a control box through a duct. The exhaust duct port is initially filtered by non-woven cotton cloth. Inside the control box, the air is further processed by a cooler or heater to achieve the desired temperature. After passing through a fiber membrane for intermediate filtration, the air is then sent to the exhaust box for further advanced filtration by absorbent cotton. This multi-layered filtration system, combining the feeding boxes, filter boxes, and purification boxes, allows for independent rearing in the feeding cages, reducing cross-infection. A corresponding fan continuously draws air from the feeding boxes. Fresh air is introduced from the top left of the animal box, while the bottom right is used to exhaust internal air through the independent feeding box, achieving unidirectional airflow, reducing dead zones and minimizing the spread of pollutants that could affect other animal rearing.

[0025] 2. This invention uses a filter cotton that is inserted into a filter box to initially filter the extracted air. With the help of a check valve, it reduces the backflow of air from inside the filter box into the feeding box, which would affect the continuous exhaust. The purification box is equipped with a baffle with ventilation slots to extend the path of the internal air. With the help of multiple activated carbon cotton, the air filtered by the filter cotton is further adsorbed and filtered, reducing the discharge of pollutants into the surrounding air.

[0026] 3. This invention utilizes the heat extracted from the air inside the animal room by setting up a heat exchange box and connecting the exhaust pipe to the return air pipe. The air inlet pipe is connected to the air supply pipe, and the incoming fresh air passes through the guide hole inside the heat exchange box. The exhaust air enters the heat exchange jacket and, with the cooperation of the spiral blades, extends the flow path in the heat exchange jacket, pre-treating the fresh air passing through the guide hole and reducing the energy consumption of the surface cooler or heater. In addition, the outer walls of the air inlet pipe, guide pipe, exhaust pipe, and exhaust pipe are all covered with heat insulation cotton to reduce the influence of the external environment on the temperature of the air passing inside.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-14 This embodiment provides a technical solution: An SPF-grade animal room air conditioning and purification system includes an animal breeding component for an animal breeding site, the animal breeding component including an animal room 8; Secondly, animal room 8 is made of color steel sandwich panels and has a movable sealed door on one side.

[0031] In this invention, the color steel sandwich panels serve as the six walls of the animal house 8, which increases the overall heat preservation effect and reduces the impact of stable changes in the external environment on large internal temperature differences, thus reducing energy consumption. The sealed door facilitates the entry and exit of operators, and the closure of the sealed door helps to increase the internal airtightness and reduce the impact of air leakage caused by gaps.

[0032] Specifically, the air supply assembly is used to draw in outside air and deliver it into the animal house 8. The air supply assembly is installed on the top of the animal breeding assembly. The air supply assembly includes an air supply box 1, with an exhaust pipe 10 at one end of the air supply box 1. The exhaust pipe 10 has a pre-filter inside, and an air supply pipe 11 at the other end of the air supply box 1.

[0033] Furthermore, the air supply box 1 is fixed to the top of the animal room 8 by bolts. The exhaust pipe 10 and the air supply box 1 are integrally formed. The bottom inner wall of the exhaust pipe 10 is provided with a limiting ring 100. Below the limiting ring 100, there is a non-woven cotton cloth 101. Below the non-woven cotton cloth 101, there is a protective net 102 for protecting the port of the exhaust pipe 10.

[0034] In this invention, the limiting ring 100 is fixed to the exhaust pipe 10 by bolts, and the bottom of the protective net 102 is inserted into the limiting groove on the side wall of the exhaust pipe 10 by corresponding clips and fixed by corresponding bolts. The limiting ring 100 and the protective net 102 fix the position of the non-woven cotton cloth 101. The protective net 102 initially intercepts the air entering the exhaust pipe 10 from the outside, filters large particles and insects, and with the cooperation of the non-woven cotton cloth 101, achieves primary filtration, intercepting dust and particulate matter in the air.

[0035] Specifically, the air supply pipe 11 is fixed to the air supply box 1 by bolts, and the end of the air supply pipe 11 is fixed to the end of the air inlet pipe 20 by bolts. A motor 12 is provided on one side of the outer wall of the air supply box 1. The output shaft of the motor 12 is connected to the impeller 120 through a coupling. The impeller 120 extends into the interior of the air supply box 1.

[0036] In this invention, the motor 12 is electrically connected to an external power source via a wire, and the control switch on the outer wall is electrically connected to the processor inside the display screen on the outer wall of the control box 4 via a wire. The processor controls the motor 12 to start, thereby rotating the impeller 120 and guiding the air from the outer port of the air supply pipe 11 to be continuously drawn into the air inlet pipe 20, thus replacing the air inside the animal room 8 and helping to ensure continuous ventilation inside.

[0037] It should be noted that the heat exchange component is used to exchange heat between the exhaust air and the extracted air. The heat exchange component is installed on the top of the animal breeding component and is connected to the air supply component on one side. The heat exchange component includes a heat exchange box 2. The two ends of the heat exchange box 2 are respectively connected to the air inlet pipe 20 and the air guide pipe 200 for extracting air. The side wall of the heat exchange box 2 is respectively connected to the exhaust pipe 21 and the discharge pipe 210, which are connected to the heat exchange jacket 22 inside the heat exchange box 2.

[0038] Furthermore, the heat exchange box 2 has a guide hole 23 that penetrates the heat exchange jacket 22 at its end. The guide holes 23 are distributed in a ring at equal intervals. The two ends of the guide holes 23 are connected to the inside of the air inlet pipe 20 and the air guide pipe 200, respectively. The heat exchange jacket 22 is provided with spiral blades 220. The exhaust pipe 21 is connected to the bottom of the heat exchange jacket 22, and the discharge pipe 210 is connected to the top of the heat exchange jacket 22.

[0039] In this invention, the guide hole 23 facilitates the passage of air entering through the air inlet pipe 20 and into the air duct 200. The spiral blade 220 and the heat exchange box 2 are integrally formed, and the guide hole 23 penetrates the spiral blade 220. The spiral blade 220 divides the interior of the heat exchange jacket 22 into a spiral shape. The extended exhaust pipe 21 draws air from the animal room 8 and spirals upward in the heat exchange box 2, increasing the path through the heat exchange box 2 and helping to wrap and fit the guide hole 23. The air discharged from the exhaust pipe 21 preheats or precools the air entering through the guide hole 23. When the air inside the animal room 8 is hot, the discharged hot air preheats the initially entering air, reducing heating and increasing energy consumption. When the air inside the animal room 8 is cold, the discharged cold air precools the initially entering air, reducing cooling and increasing energy consumption.

[0040] Specifically, the control component is used to perform intermediate filtration processing on the air after heat exchange. The control component is installed inside the animal room 8 and is connected to the end of the air duct 200 on the heat exchange component. The control component includes a control box 4, and the control box 4 has a partition plate 42 inside. The left compartment of the partition plate 42 is used for preheating or precooling the air after heat exchange, and the right compartment of the partition plate 42 is equipped with a medium-efficiency filter.

[0041] Furthermore, the control box 4 is connected to the bottom of the inner wall of the animal room 8 by bolts. The partition plate 42 and the control box 4 are integrally formed. The compartment on the left side of the partition plate 42 is provided with a surface cooler 40 and a heater 41 in sequence. The bottom of the surface cooler 40 is fixed to the control box 4 by bolts. The heater 41 is fixed to the control box 4 by bolts. The air inlet port on the left end of the surface cooler 40 is connected to the end of the air duct 200. The exhaust port on the right end of the surface cooler 40 is connected to the bottom air inlet on the left end of the heater 41. The top exhaust port on the right end of the heater 41 is connected to the compartment on the right side of the partition plate 42 through a pipe. In this invention, a display screen is provided on the outer wall of the control box 4 to display the overall working status. The display screen is equipped with a processor, which controls the air supply box 1 to continuously supply air and controls the surface cooler 40 and heater 41 to start accordingly. The surface cooler 40 cools the air entering the interior from the air duct 200, and the heater 41 preheats the air entering the interior. The surface cooler 40 and heater 41 are controlled independently, and only one can be started at a time. A temperature sensor is provided at the end connection port of the heater 41 to detect the temperature of the initially entering air. The temperature of the initially entering air can be viewed in real time through the display screen. The surface cooler 40 cools and dehumidifies the air by absorbing heat through refrigerant evaporation or by exchanging sensible heat with chilled water. The heater 41 transfers heat to the air through a heat transfer medium to raise the air temperature. When hot air needs to be introduced into the animal room 8 for heating, the surface cooler 40 stops operating, and the heater 41 is activated by a control switch on the heater 41 via a feedback signal from the processor to heat the air entering through the air duct 200. The temperature sensor monitors the heated air in real time. When the set threshold is reached, the heater 41 stops heating and maintains the current temperature to heat the air. When cold air needs to be introduced into the animal room 8 for cooling, the heater 41 stops operating, and the surface cooler 40 is activated by a control switch on the surface cooler 40 via a feedback signal from the processor to cool the air entering through the air duct 200. The temperature sensor monitors the cooled air in real time. When the set threshold is reached, the surface cooler 40 stops cooling and maintains the current temperature to cool the air.

[0042] Secondly, a through slot 44 is provided on the top of the control box 4 at the right side of the partition plate 42. A medium-efficiency filter is symmetrically arranged in the compartment near the right side of the partition plate 42 inside the control box 4. The medium-efficiency filter is a fiber membrane cloth 43. A first top cover 45 is provided at the top opening on the left side of the partition plate 42. A second top cover 46 is provided in the through slot 44. A connecting pipe 47 communicating with the interior is provided at the top right end of the control box 4. The top of the connecting pipe 47 extends into the exhaust box 7.

[0043] In this invention, the partition plate 42 divides the inside of the control box 4 into two compartments. The left compartment pre-treats the incoming air, and the right compartment performs medium-efficiency interception filtration on the pre-treated air. The fiber membrane cloth 43 is tightly inserted into the right compartment. The first top cover 45 is fixed to the top left side of the control box 4 with bolts. The bottom of the second top cover 46 is provided with a rubber pad, which is inserted into the through groove 44 and fixed. The second top cover 46 is fixed to the top right side of the control box 4 with bolts. With the cooperation of the connecting pipe 47, the medium-efficiency filtered air is delivered to the exhaust box 7.

[0044] It is worth adding that the exhaust assembly is used to guide the pre-treated air from the top of the animal room 8 for discharge. The exhaust assembly is installed in the animal room 8 and is connected to the end of the control assembly. The exhaust assembly includes an exhaust box 7, in which a high-efficiency filter is provided, and an air outlet 72 for adjusting the air direction is provided on the exhaust box 7.

[0045] Specifically, a slot 70 is provided in the middle of the lower surface of the exhaust box 7, a sealing bottom cover 71 is provided in the slot 70, a connecting groove 710 is provided in the middle of the sealing bottom cover 71, an absorbent cotton 711 is provided in the connecting groove 710, and an air regulating port 72 communicating with the interior is provided near the right end of the lower surface of the exhaust box 7, and a louver 720 for rotating and adjusting the direction is provided in the air regulating port 72.

[0046] In this invention, the sealing bottom cover 71 is inserted into the corresponding slot 70, and a rubber gasket is provided on the sealing bottom cover 71 to increase the sealing performance of the insertion between the sealing bottom cover 71 and the slot 70. The sealing bottom cover 71 is fixed to the exhaust box 7 by bolts. The absorbent cotton 711 is inserted into the connecting groove 710. The air entering the exhaust box 7 from the connecting pipe 47 is filtered three times by the absorbent cotton 711 to reduce the discharge of small particles into the animal room 8. The absorbent cotton 711 is made of polytetrafluoroethylene material, which fully absorbs and filters the passing air. The louvers 720 are evenly spaced, and the louvers 720 are rotatably connected to the air regulating port 72 by a rotating shaft. The direction can be manually adjusted according to the direction of exhaust.

[0047] Secondly, the cage assembly is used for fixed-point animal breeding and air purification. The cage assembly is installed inside the animal room 8 and is connected to the exhaust pipe 21 on the heat exchange assembly. The cage assembly includes several feeding boxes 9. A filter box 5 and a purification box 6 are arranged in sequence on the right side of the feeding box 9. A blower assembly is provided on one side of the feeding box 9 and the blower assembly is connected to the filter box 5 through a check valve 50. The filter box 5 and the purification box 6 are connected internally. A return air pipe 3 is provided on one side of the purification box 6 and the return air pipe 3 is connected to the exhaust pipe 21.

[0048] Furthermore, the feeding boxes 9 are evenly spaced, and each feeding box 9 has a feeding chamber 90 on its top. Each feeding chamber 90 contains a feeding cage 900. Each feeding cage 900 has a connecting bucket 91 on its right end. Each connecting bucket 91 has a round tube 910 on its right end. The inner wall of the round tube 910 is equipped with a blower assembly, which includes a blower duct 912. Each blower duct 912 contains a fan 913. The end of the round tube 910 is equipped with a positioning ring 911. The positioning ring 911 is fixed to the outer end of the check valve 50 by bolts.

[0049] In this invention, the feeding boxes 9 are independently separated, and the feeding cages 900 are easy to remove and replace, enabling independent animal breeding without interference. A screen is installed at the junction of the connecting bucket 91 and the feeding box 9 to prevent animal hair from entering. The fan 913 is fixed to the blower 912 with bolts and electrically connected to the processor on the display screen on the outer wall of the control box 4 via wires. Each fan 913 is individually controlled and activated. When a fan 913 is activated, it promptly extracts and discharges air from the corresponding feeding box 9. The positioning ring 911 helps to fit tightly and securely with the check valve 50. The exhaust box 7 draws air in from the top left side of the animal room 8 and extracts air from the bottom right side of the animal room 8 at the connecting bucket 91, achieving unidirectional airflow from left to right inside the animal room 8. This avoids dead air zones, reduces the risk of untimely air exchange inside the animal room 8, and prevents internal air pollution from spreading and affecting the breeding of animals in other feeding boxes 9, thus reducing the risk of cross-infection.

[0050] Furthermore, the inner end of the check valve 50 is fixed to the filter box 5 with bolts. Each filter box 5 has a filter chamber 51 inside. The bottom of the side wall of the filter chamber 51 has a connecting groove 510 that communicates with the inside of the purification box 6. The filter chamber 51 is provided with filter cotton 511. Each filter box 5 has a third top cover 512 on top.

[0051] In this invention, the check valve 50 guides air out in one direction to avoid the backflow of air inside the filter box 5. With the cooperation of the connecting groove 510, the inside of the filter box 5 is connected to the inside of the purification box 6. The filter cotton 511 filters the air initially drawn from the feeding cage 900 to reduce the discharge of particulate matter. The lower surface of the third top cover 512 is provided with a rubber pad to increase the sealing between the third top cover 512 and the filter box 5. The third top cover 512 is fixed to the filter box 5 by bolts. The bolts can be removed to facilitate the opening of the third top cover 512 to remove and replace the internal filter cotton 511.

[0052] In addition, the purification box 6 has a purification chamber 60 inside, and baffles 61 are symmetrically arranged in the purification chamber 60. The baffles 61 and the purification box 6 are integrally formed. The left baffle 61 has a ventilation slot 610 near the top, and the right baffle 61 has a ventilation slot 610 near the bottom. Activated carbon cotton 63 is provided on both sides of the baffles 61. The top of the purification box 6 is provided with a fourth top cover 62. The return air duct 3 is connected to the inside of the purification chamber 60. The top of the return air duct 3 is fixed to the bottom of the exhaust air duct 21 by bolts.

[0053] In this invention, with the cooperation of baffle 61, the purification chamber 60 is divided into multiple chambers. With the cooperation of corresponding ventilation slots 610, the separated chambers are interconnected, increasing the air passage from the left chamber to the right chamber. Multiple activated carbon cotton 63 further adsorb and filter the air filtered from the filter box 5, reducing the impact of pollutant discharge on the surrounding environment. The return air duct 3 cooperates with the exhaust air duct 21 to guide the air discharged from the animal room 8 into the heat exchange jacket 22 in the heat exchange box 2. The exhaust air pre-treats the incoming air, reducing the energy consumption for heating or cooling. The corresponding air inlet duct 20, air guide duct 200, exhaust duct 21, and discharge pipe 210 are all covered with heat insulation cotton to reduce the impact of external temperature changes on the temperature of the passing air.

[0054] In this embodiment, the SPF-grade animal room air conditioning and purification system is used by first fixing the air supply box 1 with the exhaust duct 10 to the top of the animal room 8 with a sealed door, and fixing the motor 12 to the outer wall of the air supply box 1. A protective cover 13 is provided on the outer wall of the air supply box 1 above the motor 12. The protective cover 13 protects the motor 12, reducing the damage caused by external rainwater contact, and the bottom of the protective cover 13 helps ventilation and heat dissipation, reducing the impact of heat accumulation. The non-woven cotton cloth 101 of the primary filter is installed between the limiting ring 100 and the protective net 102. The heat exchange box 2 is fixed to the top of the air supply box 1 with bolts, and the air inlet duct 20 connects the air supply duct 11 and the heat exchange box 2. The air duct 200 connects the heat exchange box 2 and the control box 4. The fiber membrane cloth 43 is installed in the right compartment of the partition plate 42 inside the control box 4. The surface cooler 40 and the heater 41 are installed in the left compartment of the partition plate 42 inside the control box 4. The air inlet port of the surface cooler 40 is connected to the bottom end of the air duct 200, and the air outlet port of the surface cooler 40 is connected to the air inlet port of the heater 41 through a hose. The air outlet port of the heater 41 is connected to the right compartment through the partition plate 42 through a pipe. With the cooperation of the connecting pipe 47, the right compartment of the partition plate 42 in the control box 4 is connected to the exhaust box 7. The sealed bottom cover 71 with absorbent cotton 711 is fixed in the exhaust box 7. The feeding box 9 is fixed inside the animal room 8 near the right end, and the feeding cage 900 is plugged into the feeding chamber 90. The connecting bucket 91 is connected to the round pipe 910 with the blower 912. With the cooperation of the positioning ring 911, it is fixedly connected to the check valve 50 on the filter box 5. The filter cotton 511 is inserted into the filter chamber 51. The purification box 6 with activated carbon cotton 63 is combined and connected to the filter box 5. The return air pipe 3 is connected to the exhaust air pipe 21. The air discharged from the animal room 8 enters the heat exchange jacket 22 in the heat exchange box 2. With the cooperation of the spiral blades 220, the internal air circulation path is increased, the fresh air is pretreated, and finally discharged from the exhaust pipe 210. The display screen on control box 4 shows the temperature of the incoming air in real time. When adjusting the temperature inside animal room 8 as needed, motor 12 is started first, drawing fresh air from air supply box 1 into control box 4. When hot air needs to be introduced into animal room 8 for heating, surface cooler 40 stops operating, and heater 41, via a feedback signal from the processor, activates its control switch to heat the air entering through air duct 200. A temperature sensor monitors the heated air in real time. When a set threshold is reached, heater 41 stops heating, maintaining the current temperature to heat the air passing through. When the animal... When room 8 needs to be cooled by introducing cold air, heater 41 stops operating, and surface cooler 40 starts its control switch via a feedback signal from the processor, cooling the air entering through air duct 200. Temperature sensor monitors the cooled air in real time, and when the set threshold is reached, surface cooler 40 stops cooling, maintaining the current temperature to cool the passing air. At the same time, an indoor thermometer is installed inside animal room 8, and the operator observes the changes in the temperature readings. Based on the required changes in indoor temperature, the operator adjusts the threshold set by the processor on the display screen, thereby adjusting the temperature of the fresh air supplied into the room. The exhaust box 7 continuously supplies fresh air to the top left side inside the animal room 8, while the feeding box 9 is located at the bottom right side inside the animal room 8. The fan 913 continuously draws air from the individual feeding cages 900, achieving one-way airflow inside the animal room 8, reducing dead airflow corners, and with the cooperation of the check valve 50, reducing air backflow inside the filter box 5. The air inside each feeding box 9 flows in one direction, reducing the impact of cross-contamination. The second top cover 46 facilitates disassembly and removal for replacement of the internal fiber membrane cloth 43. The third top cover 512 and the fourth top cover 62 are also easy to disassemble and open for replacement of the internal filter cotton 511 and activated carbon cotton 63, which helps to continuously filter and intercept the filter.
