Description

Technical Field

[0001] This utility model belongs to the field of cage frame dust removal and sterilization technology, specifically relating to an IVC cage frame duct cleaning component and sterilization equipment. Background Technology

[0002] Laboratory animals refer to all kinds of animals used in scientific experiments, including animals that have been domesticated and bred according to scientific requirements, whose microorganisms are controlled, and whose genetic background or origin is clear. Currently, the mainstream housing equipment for mice and rats is the IVC (Individually Ventilated Cage Rack), which is widely used in rodent experiments in research institutions, pharmaceutical companies, and university laboratories. Currently, IVC cages achieve independent air circulation and filtration within each cage through active air supply and return control, effectively preventing cross-infection and improving the reliability of experimental data and animal welfare.

[0003] However, after prolonged use, IVC cages accumulate a lot of dust in the return air ducts and branch pipes. The return air duct is a main pipe horizontally positioned below the cage, while several branch pipes are perpendicular to the duct and connected to its upper side. These branch pipes then connect to the individual cage boxes. Both the return air duct and branch pipes require manual cleaning. Currently, the common cleaning method involves moving the IVC cage out of the barrier area, removing the branch pipes, and using a large cleaning machine. This is very cumbersome, time-consuming, and requires a significant amount of manpower to clean each cage. Existing technology also includes equipment for sterilizing cages, but existing sterilization equipment is insufficient for cleaning branch pipes and cannot completely achieve the processes of dust removal, sterilization, and ventilation.

[0004] Chinese invention patent application number 202210328554.9 discloses an integrated dust removal and sterilization device for IVC cages, including a chassis body, an air inlet pipe, a filter mechanism, a wind-driven mechanism, a disinfection mechanism, an exhaust pipe, a dust collection bin, an electric straight-through valve, an electric three-way valve, and a transfer pipe. The wind-driven mechanism generates driving force to draw the dirty airflow entering through the air inlet pipe into the filter mechanism for filtration. The filtered airflow is then disinfected by the disinfection mechanism before being discharged from the exhaust pipe, thus integrating the filtration and disinfection of dirty airflow. By controlling the opening and closing of the electric straight-through valve and the electric three-way valve, and changing the connection method of the transfer pipe and the wind-driven direction of the wind-driven mechanism, the air duct path can be changed on the original structure, allowing the dust filtered by the filter mechanism to be discharged and deposited in the dust collection bin without disassembling or replacing the filter mechanism. This makes the equipment simple and convenient to operate, shortens downtime, and improves cleaning efficiency. However, it only uses a high-powered fan to extract and filter the airflow in the intake pipe, but the dust and dirt attached to the inner walls of the intake pipe and each branch pipe are difficult to be sucked away. Therefore, the cleaning power is limited and it cannot completely clean the intake and exhaust pipes and each branch pipe. Utility Model Content

[0026] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-6 The present invention will be further described below.

[0027] like Figures 1-3As shown, this utility model discloses an IVC cage duct cleaning assembly, including a main body 13, a support rod 7, a main pipe brush 1, and branch pipe brushes 6. The support rod 7 is horizontally arranged, and one end of the support rod 7 is fixedly connected to the main body 13. The main pipe brush 1 is located at the other end of the support rod 7 and is arranged along the length of the support rod 7. The return air duct of the cage is horizontally arranged on the lower side of the cage. The support rod 7 drives the front end of the main pipe brush 1 to enter the return air duct from one end of the return air duct. The main pipe brush 1 is connected to a rotation drive component, which drives the main pipe brush 1 to rotate and clean the inner wall of the return air duct. Several thinner branch pipes are connected to the upper side of the return air duct. The branch pipes are connected to each cage box to supply air to the cage box. Therefore, the branch pipe brush 6 is required to clean the branch pipes. The branch pipe brush 6 is set perpendicular to the main pipe brush 1, and the branch pipe brush 6 is connected to a telescopic drive component. When the branch pipe brush 6 moves to the bottom of the branch pipe, the telescopic drive component drives the branch pipe brush 6 to extend, so that the branch pipe brush 6 moves along the branch pipe and cleans the inner wall of the branch pipe. The main body 13 is provided with a moving wheel 14 on the lower side, which pushes the main body 13 to move the main pipe brush 1 along the return air duct, and at the same time moves the position of the branch pipe brush 6, so that the branch pipe brush 6 cleans each branch pipe in turn.

[0028] A fixing block 2 is fixedly installed at the other end of the support rod 7. The main brush 1 and the branch brush 6 are both installed on the fixing block 2. An installation port is opened on the fixing block 2. The rotating drive is the main brush motor 3. The main brush motor 3 is installed on the installation port of the fixing block 2. The main brush 1 is connected to the output shaft of the main brush motor 3. The rotation shaft of the main brush 1 coincides with the central axis of the return air duct. The main body 13 is moved to make the main brush 1 move along the return air duct. At the same time, the main brush 1 rotates to clean the inner wall of the return air duct.

[0029] A guide hole 5 is vertically formed on the fixed block 2. A steel wire rope 8 is connected to the lower end of the branch brush 6. The steel wire rope 8 is flexible but has a certain supporting rigidity. An installation groove 18 is formed along the length direction on the support rod 7 and the fixed block 2. The end of the installation groove 18 communicates with the guide hole 5. The steel wire rope 8 is locked in the installation groove 18. One end of the steel wire rope 8 passes through the guide hole 5 and is connected to the branch brush 6. The other end of the steel wire rope 8 is connected to the telescopic drive assembly. When the branch brush 6 moves to the bottom of the branch pipe, the telescopic drive assembly drives the steel wire rope 8 to move to the front end. The wire rope 8 moves along the mounting groove 18 towards the end closer to the main brush 1, and the wire rope 8 pushes the branch brush 6 to move upward into the branch pipe. After the branch brush 6 enters the branch pipe, the wire rope 8 continues to push the branch brush 6, so that the branch brush 6 moves along the branch pipe and cleans the inner wall of the branch pipe. After cleaning to the upper end of the branch pipe, the telescopic drive assembly drives the wire rope 8 to retract, so that the branch brush 6 descends along the branch pipe until it leaves the branch pipe. Then the main body 13 is moved so that the branch brush 6 moves to the position of the next branch pipe and continues to clean the next branch pipe until all the side-by-side branch pipes are cleaned.

[0030] The telescopic drive assembly in this embodiment includes a synchronous belt 10 and two pulleys 9. The two pulleys 9 are rotatably mounted at both ends of the support rod 7. The synchronous belt 10 is wrapped around the outside of the two pulleys 9 and is located on one side of the wire rope 8. The pulley 9 near the main body 13 is connected to a branch motor 12. The rotation of the branch motor 12 causes the pulley 9 to rotate, which in turn causes the synchronous belt 10 to rotate around the two pulleys 9. The other end of the wire rope 8 is fixedly connected to the synchronous belt 10 by a fixing clamp 11. When the synchronous belt 9 rotates, the wire rope 8 is also driven by the synchronous belt 9 and moves along the mounting groove 18. When the branch motor 12 reverses, the synchronous belt 9 also reverses, and the wire rope 8 is driven by the synchronous belt 9 and moves in the opposite direction along the mounting groove 18, thereby realizing the process of the wire rope 8 extending to the front end or retracting.

[0031] A camera device 4 is installed on one side of the branch brush 6, mounted on the fixing block 2. A display screen 15 is installed on the main body 13. The camera device 4 and the display screen 15 are connected by wires. The camera device 4 monitors in real time whether the branch brush 6 accurately reaches the bottom of the branch pipe, facilitating cleaning of the branch pipe. A touch screen 16 is also installed on the main body 1, which can control the on / off of the main brush motor 3 and the branch brush motor 12, making operation more convenient. Because the support rod 7 is relatively long, although it can be supported by the return air duct after entering it, when not in use, the support rod 7 needs to be supported by the bracket 17 to prevent it from breaking. Both the main brush 1 and the branch brush 6 can be replaced with brushes of different hardness, making it convenient and quick to clean the dust inside the IVC cage return air duct and branch pipes.

[0032] When using the duct cleaning assembly, move the main body 13 to move the main brush 1 along the return air duct. At the same time, the main brush 1 rotates to clean the inner wall of the return air duct. The camera device 4 monitors the branch brush 6 reaching the bottom of the branch duct. The branch motor 12 rotates, and the wire rope 8 is driven by the synchronous belt 9 and moves towards the front end along the mounting groove 18. The branch brush 6 enters the branch duct and moves along the branch duct to clean. After cleaning to the upper end of the branch duct, the branch motor 12 reverses, and the wire rope 8 drives the branch brush 6 to retract. Then move the main body 13 to move the branch brush 6 to the position of the next branch duct and continue cleaning the next branch duct until all the branch ducts in the row have been cleaned.

[0033] like Figure 4As shown, this utility model discloses an IVC cage sterilization device, including a frame 19, an air inlet duct 20, an air duct dust removal mechanism, a wind-driven mechanism, a disinfection mechanism, and an air outlet duct 31. The air duct dust removal mechanism includes a separately configured air duct cleaning component and a filter component. The filter component, the wind-driven mechanism, and the disinfection mechanism are all mounted on the frame 19. The air duct cleaning component enters the return air duct from one end and cleans the dust off the inner walls of the return air duct and branch pipes. One end of the air inlet duct 20 is connected to the other end of the return air duct. The other end of 20 is connected to the air inlet of the filter assembly and one end of the ventilation detection pipe 42 via a three-way valve 29. The filter assembly and the wind-driven mechanism extract and filter the dust. The other end of the ventilation detection pipe 42 is connected to the air inlet of the wind-driven mechanism. The air outlet of the filter assembly is also connected to the air inlet of the wind-driven mechanism. The air outlet of the wind-driven mechanism is connected to the disinfection mechanism. The disinfection mechanism is connected to one end of the air outlet pipe 31. The other end of the air outlet pipe 31 is connected to the air inlet pipe of the cage. After the dust is sucked out, it is disinfected by the disinfection mechanism.

[0034] like Figures 5-6 As shown, one end of the air inlet pipe 20 is connected to the return air pipe, and the other end of the air inlet pipe 20 is connected to the filter assembly and the ventilation detection pipe 42 respectively through a three-way valve 29. The three-way valve 29 is connected to a first air inlet switching valve 21. The first air inlet switching valve 21 can be electrically controlled to select which path the three-way valve 29 is connected to. The air outlet of the filter assembly is connected to the air inlet of the wind-driven mechanism through a pipe. In this embodiment, the wind-driven mechanism is a fan 24. An air inlet pipe 30 is connected to the air inlet of the fan 24. The air inlet pipe 30 is connected to the pipe of the air outlet of the filter assembly and the ventilation detection pipe 42 respectively through the three-way valve 29. The three-way valve 29 is connected to a second air inlet switching valve 28. In this embodiment, the filter component is a filter box 22, and a dust collection box 23 is provided below the filter box 22. The fan 24 draws the dust in the return air duct into the filter box 22 through the air inlet pipe 20. After being filtered by the medium-efficiency filter in the filter box 22, the dust settles into the dust collection box 23 below the filter box 22. Finally, the dust collection box 23 can be removed and the dust can be disposed of.

[0035] The disinfection mechanism includes a sterilization component and a harmless treatment component. The air outlet of the fan 24 is connected to an air outlet pipe 35. The air outlet pipe 35 is connected to the sterilization component and the harmless treatment component respectively through a three-way valve 29. The three-way valve 29 is connected to an air outlet switching valve 34. The sterilization component and the harmless treatment component are both connected to the air outlet pipe 31 through the three-way valve 29. The disinfection mechanism delivers the disinfection medium to the air inlet pipe of the cage frame through the air outlet pipe 31, thereby delivering it to each air duct of the cage frame and the cage box for disinfection. After disinfection, the remaining disinfection medium is harmlessly treated by the harmless treatment component and the air ducts of the cage frame are ventilated.

[0036] The sterilization assembly includes a vaporization chamber 32, a metering pump 37, and a storage tank 38. One end of the vaporization chamber 32 is connected to a blower pipe 35 via a three-way valve 29, and the other end of the vaporization chamber 32 is connected to an air outlet pipe 31 via a three-way valve 29. A liquid inlet 33 is provided on the vaporization chamber 32, and a liquid outlet 39 is provided on the storage tank 38. The storage tank 38 and the vaporization chamber 32 are connected by a liquid supply pipeline. The metering pump 37 is connected to the liquid supply pipeline. The metering pump 37 delivers the hydrogen peroxide disinfectant solution in the storage tank 38 to the vaporization chamber 32. After vaporization in the vaporization chamber 32, the blower 24 delivers the vaporized hydrogen peroxide to the cage for disinfection through the air outlet pipe 31.

[0037] The harmless treatment component is filter 36. The air inlet of filter 36 is connected to the air outlet pipe 35 via a three-way valve 29, and the air outlet of filter 36 is connected to the air outlet pipe 31 via a three-way valve. Filter 36 contains a hydrogen peroxide gas rapid decomposer. When hydrogen peroxide comes into contact with the decomposer, it is decomposed into water and oxygen, causing no pollution and being harmless to the human body. A detection chamber 25 is set in the middle of the ventilation detection pipe 42. The detection chamber 25 is equipped with a temperature and humidity sensor 26 and a concentration sensor 27, which can detect the temperature and humidity of the air drawn from the cage and the hydrogen peroxide concentration. When the concentration sensor 27 detects that the hydrogen peroxide concentration is 0, the hydrogen peroxide has been completely decomposed, and the sterilization process is completed. A control panel 40 is also set on the rack 19. The control panel 40 can control the switching of each electric switching valve and the operation of each component, making it more convenient to use.

[0038] In addition to the duct cleaning components, this disinfection equipment can also disinfect rooms. The frame 19 is moved indoors, the air inlet duct 20 is not connected to any pipes or items, and the horn tube 41 is connected to the end of the air outlet duct 31 so that the end of the air outlet duct 31 can discharge air in four directions. No dust removal step is required. The amount of disinfectant is set according to the volume of the room, and it can also disinfect the room.

[0039] In use, the IVC cage sterilization equipment of this utility model involves moving the duct cleaning assembly to one end of the return air duct. The assembly cleans the inner walls of the return air duct and its branch pipes, removing dust adhering to them. Simultaneously, the inlet air duct 20 is connected to the other end of the return air duct. The first inlet switching valve 21 controls the connection between the inlet air duct 20 and the filter box 22, temporarily disconnecting the inlet air duct 20 from the ventilation detection pipe 42. The second inlet switching valve 28 controls the connection between the inlet fan pipe 30 and the filter box 22. The outlet switching valve 34 controls… The blower pipe 35 is connected to the gasification chamber 32, but the gasification chamber 32 is not working at this time and only serves as a passage. After cleaning, the air duct cleaning component can be removed from the return air duct. The blower 24 draws the dust in the cage air duct into the filter box 22 through the air inlet pipe 20. After being filtered by the medium-efficiency filter in the filter box 22, the dust settles into the dust collection box 23 below the filter box 22. The blower pipe 35, the gasification chamber 32 and the air outlet pipe 31 of the blower 24 serve as a circulation passage until the set dust removal time ends. At this time, the dust removal stage of the cage is completed.

[0040] Next, the first air inlet switching valve 21 controls the air inlet pipe 20 to connect with the ventilation detection pipe 42. The air inlet pipe 20 temporarily does not pass through the filter box 22. The second air inlet switching valve 28 controls the air inlet fan pipe 30 to connect with the ventilation detection pipe 42. The ventilation detection pipe 42 serves as a circulating ventilation pipe. The air outlet switching valve 34 controls the air outlet fan pipe 35 to connect with the vaporization chamber 32. At this time, the vaporization chamber 32 begins to heat up until it reaches the set temperature. The metering pump 37 operates, delivering the hydrogen peroxide liquid in the storage tank 38 to the vaporization chamber 32. After entering the vaporization chamber 32, the hydrogen peroxide is vaporized. Then, the air outlet of the fan 24 delivers the vaporized hydrogen peroxide in the vaporization chamber 32 from the air outlet pipe 31 to the air inlet pipe of the cage frame, and then from the air inlet pipe to each branch pipe and cage box for disinfection until the set disinfection time is completed. At this time, the sterilization stage of the cage frame is completed, and both the vaporization chamber 32 and the metering pump 37 stop working.

[0041] Then, the outlet switching valve 34 controls the connection between the outlet fan pipe 35 and the filter 36. At this time, the cage frame duct, inlet pipe 20, ventilation detection pipe 42, filter 36, and outlet pipe 31 form a passage. The hydrogen peroxide in the cage frame duct enters the filter 36 and is decomposed into water and oxygen. When the concentration sensor 27 detects that the concentration of hydrogen peroxide is 0, the hydrogen peroxide is completely decomposed, the ventilation ends, and the entire dust removal and sterilization process is completed. This utility model can complete the overall dust removal, sterilization, and ventilation of the cage frame. With the duct cleaning component, the return air duct and each branch pipe can be cleaned and disinfected. Each three-way valve 29 of this application is connected to an electric switching valve, which automatically switches the interface of the three-way valve 29. The whole process is automated. Moreover, this equipment does not require disassembly of the cage frame during use, making it more convenient to use and with higher cleaning efficiency. In addition, the hydrogen peroxide in this equipment is treated to render it harmless, which will not cause environmental pollution and reduce harm to the human body.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
