Description
Technical Field
[0001] This utility model relates to the technical field of gas treatment devices, specifically to an air treatment device for a sterilizer. Background Technology
[0002] During the use of sterilizers, exhaust gas is usually emitted, which can easily pollute the air. Therefore, air handling units are generally used to sterilize and filter the exhaust gas emitted by the sterilizer, thereby preventing air pollution and facilitating the use of the sterilizer.
[0003] A Chinese patent, CN218011496U, discloses a gas treatment device for a vertical pressure steam sterilizer. This device introduces gas discharged from the steam sterilizer body into the interior of a curved tube and reheats it via a heating coil for sterilization. The sterilized gas is partially liquefied through a condenser and, driven by a vacuum pump, enters a first and second filter box. Both filter boxes contain filter elements to filter harmful impurities. The treated gas enters the upper part of a buffer chamber and is discharged through a second exhaust pipe to prevent air pollution. However, in use, this device typically requires connecting the curved tube to the first exhaust pipe on one side of the steam sterilizer body, often using welding or flange connections. These methods make it difficult to quickly connect the device to the sterilizer exhaust pipe and hinder disassembly, thus complicating installation and use. Utility Model Content

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0030] This utility model provides, for example Figures 1-11 The sterilizer air handling device shown includes a handling device body 1, with an air inlet 2 at one end and an exhaust 4 at the other end.
[0031] A quick-connection structure 3 is provided on one side of the air inlet 2, and the quick-connection structure 3 includes a connecting ring 31 fixed on the side wall of the air inlet 2. The connecting ring 31 has multiple cavities 36 arranged in a ring array inside, and a movable connecting plate 38 is provided inside the multiple cavities 36. The multiple cavities 36 are all connected to the inside of the connecting ring 31. A clamping block 33 is installed on one side of the connecting plate 38, and a pull rod 34 extending to the outside of the connecting ring 31 is fixed on the other side. A spring 37 is also connected between one side of the connecting plate 38 and the inner wall of the cavity 36. The spring 37 is sleeved on the outside of the pull rod 34. A sterilizer 6 is provided on one side of the processing device body 1. A sterilizer exhaust pipe 5 is connected to one side of the sterilizer 6, and the sterilizer exhaust pipe 5 is connected to the air inlet 2 through the quick-connection structure 3.
[0032] Specifically, the processing device body 1 includes a processing box 11. Inside the processing box 11, from left to right, are installed a heating element 12, a partition 13, a condenser plate 14, a pump body 15, a bracket 19, and a buffer box 18. A first filter cartridge 16 and a second filter cartridge 17 are mounted on the bracket 19. The air inlet end 2 and the air outlet end 4 are detachably installed on both sides of the processing box 11. An air supply pipe connects the partition 13 to the inlet end of the condenser plate 14, and a connection is made between the outlet end of the condenser plate 14 and the inlet of the pump body 15. An air outlet pipe is connected between the outlet of the pump body 15 and the inlet of the first filter cartridge 16, and an air supply pipe is connected between the outlet of the first filter cartridge 16 and the inlet of the second filter cartridge 17. A pipe is connected between the outlet of the second filter cartridge 17 and the buffer box 18, and a water supply pipe is connected between one side of the second filter cartridge 17 and the first filter cartridge 16 and the buffer box 18. A drain pipe extending to the bottom of the processing box 11 is connected to the bottom of the buffer box 18, and an air outlet facing the exhaust end 4 is provided on one side of the buffer box 18. Specifically, the heating element 12 can be an electric heating wire or an electric heating tube. The condenser plate 14 is provided with a condenser tube to cool the gas, and the condenser tube has an inlet and an outlet for the cooling medium to enter and exit. This is existing technology and is not shown in the figure. The first filter cartridge 16 and the second filter cartridge 17 are both provided with filter elements. The buffer box 18 is provided with a horizontal plate that divides its interior, so that the upper cavity of the buffer box 18 is used to store and discharge gas, while the lower cavity is used to store the liquid discharged from the first filter cartridge 16 and the second filter cartridge 17, which can be discharged through the drain pipe.
[0033] As described above, during use, the processing device body 1 can be installed on one side of the sterilizer 6, and the sterilizer exhaust pipe 5 can be inserted into the connecting ring 31. At this time, the end of the sterilizer exhaust pipe 5 presses against the clamping block 33, causing the clamping block 33 to press against the spring 37 through the connecting plate 38 until the clamping block 33 is retracted into the cavity 36. Then, the end of the sterilizer exhaust pipe 5 is inserted into the connecting ring 31. At this time, the spring 37 pushes the clamping block 33 out of the cavity 36 through the connecting plate 38, causing the clamping block 33 to press against the end of the sterilizer exhaust pipe 5, thereby connecting the sterilizer exhaust pipe 5 with the air inlet 2, thus realizing the connection between the processing device body 1 and the sterilizer exhaust pipe. The sterilizer 6 is quickly connected to the exhaust pipe 5 and the exhaust gas generated during operation is discharged into the treatment box 11 through the exhaust pipe 5 and the inlet 2. At this time, the partition 13 blocks the exhaust gas and the heating element 12 heats the exhaust gas to achieve sterilization. The sterilized gas is fed into the condenser plate 14 through the air supply pipe and partially liquefied. Then, driven by the pump body 15, the gas is discharged into the first filter cartridge 16 and the second filter cartridge 17 in sequence to filter out harmful impurities in the gas. The filtered gas is fed into the upper part of the buffer box 18 through the pipeline and discharged through the outlet and exhaust end 4, thereby achieving the exhaust gas treatment of the sterilizer 6.
[0034] It should be noted that the structure of each component inside the processing device body 1 and the principle of gas treatment in this embodiment are all existing technologies. For details, please refer to the prior art (Announcement No.: CN218011496U, Name: A Gas Treatment Device for a Vertical Pressure Steam Sterilizer), which will not be elaborated here.
[0035] Furthermore, to ensure a tight seal when the sterilizer exhaust pipe 5 is connected to the connecting ring 31, such as... Figures 4-7 As shown, a sealing gasket 32 is also installed inside the connecting ring 31.
[0036] Furthermore, to facilitate the insertion of the sterilizer exhaust pipe 5 into the connecting ring 31, such as... Figure 4 and Figure 6 As shown, the top of the clamping block 33 is obliquely cut to form an inclined portion.
[0037] Meanwhile, in this embodiment, such as Figures 4-8 As shown, the connecting ring 31 is also provided with a plug-in structure for limiting the pull rod 34. The plug-in structure includes multiple fixing plates 311 installed on the outer circumference of the connecting ring 31. A pin rod 35 is inserted into one side of the fixing plate 311. One end of the pull rod 34 passes through the fixing plate 311. The pull rod 34 is provided with a first pin hole 39 and a second pin hole 310 for the pin rod 35 to be inserted.
[0038] When the sterilizer exhaust pipe 5 is inserted into the connecting ring 31, the clamping block 33 presses against the sterilizer exhaust pipe 5 under the action of the spring 37. At this time, the pin 35 can be inserted into the second pin hole 310 to limit the pull rod 34, preventing the problem of the sterilizer exhaust pipe 5 disengaging from the connecting ring 31 due to accidental pulling of the pull rod 34. When disassembling the sterilizer exhaust pipe 5, the pin 35 can be pulled out from the second pin hole 310 first, and then the pull rod 34 can be pulled. This causes the pull rod 34 to pull the clamping block 33 into the cavity 36 through the connecting plate 38. At this time, the connecting plate 38 compresses the spring 37, causing the spring 37 to contract. Then, the pin rod 35 is inserted into the first pin hole 39 to limit the pull rod 34. This process is repeated to retract multiple clamping blocks 33 into the corresponding cavities 36. Subsequently, the sterilizer exhaust pipe 5 is pulled out from the connecting ring 31, thereby disassembling the sterilizer exhaust pipe 5 and facilitating the disassembly of the device.
[0039] Furthermore, such as Figure 6 and Figure 7 As shown, baffles are fixed on both sides of the inner wall of cavity 36, and when the clamping block 33 is retracted into cavity 36, one side of connecting plate 38 abuts against the baffles. Based on this, connecting plate 38 can be positioned to facilitate the quick insertion of pin 35 into first pin hole 39.
[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
