Description

Technical Field

[0001] This utility model relates to the field of anesthetic waste gas treatment technology, and in particular to an anesthetic waste gas adsorber. Background Technology

[0002] In current anesthetic waste gas adsorption equipment, the connection design of the inlet and outlet joints to the external gas pipes in some devices suffers from insufficient stability. Due to the simple connection structure or lack of effective fixing measures, the joints are prone to loosening or even falling off during actual use due to vibration, external force, or improper operation, leading to gas leakage. At the same time, the filtration and adsorption structures inside traditional adsorbers are often too simplistic, making it difficult to effectively remove various harmful components from anesthetic waste gas, resulting in the exhaust gas still potentially posing a threat to the environment and human health. Therefore, we propose an anesthetic waste gas adsorber. Utility Model Content

[0003] The main objective of this invention is to provide an anesthetic waste gas adsorber that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An anesthetic waste gas adsorber includes an adsorber body. An air inlet connector communicating with the interior of the adsorber body is integrally formed at the upper end of the adsorber body, and an air outlet connector communicating with the interior of the adsorber body is integrally formed at the lower end of the adsorber body. Positioning members are fixedly connected to both the upper and lower ends of the adsorber body, and the two positioning members are coaxially arranged with the air inlet connector and the air outlet connector, respectively.

[0006] Preferably, a pre-filter layer and a molecular sieve layer are fixedly installed inside the adsorber body, with the pre-filter layer located above the molecular sieve layer, and an adsorption layer is provided between the pre-filter layer and the molecular sieve layer.

[0007] By adopting the above technical solution: the pre-filter layer can intercept particulate matter and other large impurities in the airflow, providing a clean airflow environment for the subsequent adsorption process; the molecular sieve layer further deeply adsorbs residual small molecule gases, ensuring that the discharged gas meets safety standards; the multi-stage treatment method not only improves the adsorption efficiency, but also extends the service life of the adsorbent, enabling the adsorber to adapt to various complex scenarios and maintain long-term stable operation.

[0008] Preferably, the adsorption layer includes an upper filter membrane and a lower filter membrane, the upper filter membrane is fixedly connected to the lower end of the pre-filtration layer, the lower filter membrane is fixedly connected to the upper end of the molecular sieve layer, and an adsorbent is filled between the upper filter membrane and the lower filter membrane.

[0009] By adopting the above technical solution, the adsorption layer is composed of an upper filter membrane and an adsorbent encapsulated in a lower filter membrane, which can efficiently adsorb the main harmful components in anesthetic waste gas.

[0010] Preferably, the positioning component includes a fixing sleeve, the lower end of which is fixedly connected to multiple foot pads arranged in a circular array. The fixing sleeve is fixedly connected to the adsorber body through the multiple foot pads, and the fixing sleeve is coaxially arranged with the air inlet or air outlet connector. Clamping plates are provided on both the left and right sides inside the fixing sleeve. Two guide rods are fixedly installed on the side of each clamping plate away from the opposite end. The two guide rods on the same side are slidably connected to the fixing sleeve. A transmission screw is movably connected to the side of each clamping plate away from the opposite end. The transmission screw is located between the two guide rods on the same side and is threadedly connected to the fixing sleeve.

[0011] Preferably, the opposing ends of the two clamping plates are integrally formed with multiple protrusions, and the multiple protrusions are distributed at equal intervals.

[0012] By adopting the above technical solution, the loosening of the first and second connecting air tubes due to vibration or external force can be effectively avoided.

[0013] Preferably, the clamping plate has an arc-shaped structure, and both the protrusion and the clamping plate are made of rubber material.

[0014] By adopting the above technical solution, friction is increased and reliable sealing performance is provided, thereby preventing gas leakage, ensuring the stability and sealing of the adsorber connection during use, and significantly improving the reliability and safety of the equipment.

[0015] Preferably, the heights of the air inlet connector and the air outlet connector are equal, and the height dimensions of both the air inlet connector and the air outlet connector are greater than the sum of the height dimensions of the fixing sleeve and the foot pad.

[0016] By adopting the above technical solution, the operable space between the air inlet and outlet connectors and the external air pipe is effectively increased, making it easier for users to connect and disassemble.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Through the unique positioning component design, the clamping plate and the transmission screw work together to firmly clamp the first and second connecting air pipes, effectively preventing loosening due to vibration or external force. At the same time, the raised strips on the surface of the clamping plate are made of rubber material, which increases friction and provides reliable sealing performance, thereby preventing gas leakage and ensuring the stability and sealing of the adsorber connection during use, significantly improving the reliability and safety of the equipment.

[0019] 2. By incorporating a multi-stage filtration and adsorption design within the adsorber body, including a pre-filtration layer, a molecular sieve layer, and an adsorption layer, highly efficient treatment of anesthetic waste gas is achieved. The pre-filtration layer intercepts particulate matter and other large impurities in the airflow, providing a clean airflow environment for the subsequent adsorption process. The adsorption layer consists of an upper and lower filter membrane encapsulating adsorbent, which can efficiently adsorb the main harmful components in the anesthetic waste gas. Finally, the molecular sieve layer further deeply adsorbs residual small molecule gases, ensuring that the discharged gas meets safety standards. This multi-stage, layered treatment approach not only improves adsorption efficiency but also extends the service life of the adsorbent, enabling the adsorber to adapt to various complex scenarios and maintain long-term stable operation.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figure 1-4 This utility model provides a technical solution:

[0027] An anesthetic waste gas adsorber includes an adsorber body 1. An air inlet connector 2 that communicates with the interior of the adsorber body 1 is integrally formed at the upper end of the adsorber body 1. An air outlet connector 3 that communicates with the interior of the adsorber body 1 is integrally formed at the lower end of the adsorber body 1. Positioning members 4 are fixedly connected to both the upper and lower ends of the adsorber body 1, and the two positioning members 4 are coaxially arranged with the air inlet connector 2 and the air outlet connector 3, respectively.

[0028] In this embodiment, a pre-filter layer 5 and a molecular sieve layer 6 are fixedly installed inside the adsorber body 1, with the pre-filter layer 5 located above the molecular sieve layer 6. An adsorption layer 7 is disposed between the pre-filter layer 5 and the molecular sieve layer 6. The adsorption layer 7 includes an upper filter membrane 71 and a lower filter membrane 72. The upper filter membrane 71 is fixedly connected to the lower end of the pre-filter layer 5, and the lower filter membrane 72 is fixedly connected to the upper end of the molecular sieve layer 6. An adsorbent 73 is filled between the upper filter membrane 71 and the lower filter membrane 72.

[0029] The above scheme utilizes a pre-filter layer 5 to intercept particulate matter and other large impurities in the airflow, providing a clean airflow environment for the subsequent adsorption process. The adsorption layer 7 consists of an upper filter membrane 71, a lower filter membrane 72, and an adsorbent 73 encapsulated within them, which can efficiently adsorb the main harmful components in the anesthetic waste gas. Finally, the molecular sieve layer 6 further deeply adsorbs residual small molecule gases, ensuring that the discharged gas meets safety standards. This multi-stage, layered treatment approach not only improves adsorption efficiency but also extends the service life of the adsorbent, enabling the adsorber to adapt to various complex scenarios and maintain long-term stable operation.

[0030] In this embodiment, the positioning component 4 includes a fixing sleeve 41. Multiple foot pads 42 are fixedly connected to the lower end of the fixing sleeve 41, and the multiple foot pads 42 are arranged in a circular array. The fixing sleeve 41 is fixedly connected to the adsorber body 1 through the multiple foot pads 42. The fixing sleeve 41 is coaxially arranged with the air inlet connector 2 or the air outlet connector 3. Clamping plates 43 are provided on both the left and right sides inside the fixing sleeve 41. Two guide rods 44 are fixedly installed on the side of each clamping plate 43 away from the opposite end. The two guide rods 44 on the same side are slidably connected to the fixing sleeve 41. The two clamping plates 43... 3. A transmission screw 45 is movably connected to the side away from the opposite end. The transmission screw 45 is located between the two guide rods 44 on the same side and is threadedly connected to the fixed sleeve 41. The opposite ends of the two clamping plates 43 are integrally formed with multiple protrusions 431, and the multiple protrusions 431 are evenly distributed. The clamping plate 43 has an arc-shaped structure. The protrusions 431 and the clamping plate 43 are both made of rubber material. The heights of the air inlet connector 2 and the air outlet connector 3 are equal, and the height dimensions of the air inlet connector 2 and the air outlet connector 3 are both greater than the sum of the height dimensions of the fixed sleeve 41 and the foot pad 42.

[0031] Through the above solution: by using the unique positioning component 4, the clamping plate 43 and the transmission screw 45 work together to firmly clamp the first connecting air pipe 8 and the second connecting air pipe 9, effectively preventing loosening caused by vibration or external force. At the same time, the protrusions 431 on the surface of the clamping plate 43 are made of rubber material, which increases friction and provides reliable sealing performance, thereby preventing gas leakage and ensuring the stability and sealing of the adsorber connection during use, significantly improving the reliability and safety of the equipment.

[0032] It should be noted that this utility model is an anesthetic waste gas adsorber. During use, firstly, the first connecting air pipe 8 is sleeved onto the air inlet connector 2, and simultaneously, the lower end face of the first connecting air pipe 8 contacts the upper end face of the adsorber body 1. At this time, the gas in the first connecting air pipe 8 can enter the adsorber body 1 through the first connecting air pipe 8 and the air inlet connector 2. Then, the transmission screws 45 on both sides of the positioning member 4 are rotated in the opposite direction. Since the transmission screws 45 are threadedly connected to the fixed sleeve 41, when the transmission screws 45 rotate, they will drive the clamping plate 43 to slide along the guide rod 44, thereby moving the clamping plate 43 towards the center by 1. The clamping plate 43 has an arc-shaped structure, and its surface is provided with multiple protrusions 431. These protrusions 431 can increase friction, ensuring that the first connecting air pipe 8 is firmly clamped between the clamping plates 43, ensuring that the first connecting air pipe 8 is firmly sleeved onto the air inlet connector. On connector 2, the second connecting air tube 9 is then securely connected to the outlet connector 3 in the same manner as described above. This prevents the first connecting air tube 8 and the second connecting air tube 9 from loosening due to vibration or other external forces during use, thus improving connection stability. Subsequently, after the gas enters the adsorber body 1, it first passes through the pre-filter layer 5, which can effectively remove particulate matter and other large impurities in the gas. Then, the gas flows into the adsorption layer 7, which consists of an upper filter membrane 71, a lower filter membrane 72, and an adsorbent 73 filled between them. The adsorbent 73 can efficiently adsorb harmful components 4 in the anesthetic waste gas. Finally, the gas passes through the molecular sieve layer 6, which further deeply adsorbs residual small molecule gases, ensuring that the discharged gas meets safety standards. The treated gas flows from the inside of the adsorber body 1 to the outlet connector 3 and is smoothly discharged to the subsequent treatment device.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
