Description

Technical Field

[0001] This utility model relates to the field of anesthetic waste gas treatment technology, specifically to an anesthetic waste gas purification and treatment device. Background Technology

[0002] There is a certain possibility of leakage when using medical anesthetic gases, resulting in a certain amount of anesthetic waste gas in the room, which can affect the people in the room. Therefore, it is necessary to purify the air to reduce the content of anesthetic waste gas in the air.

[0003] Current filtration devices typically use fans to draw in air and activated carbon or other air-purifying materials to adsorb anesthetic waste gas. However, with prolonged use, the effectiveness of the activated carbon and other materials used to adsorb anesthetic waste gas gradually decreases until they become ineffective. Therefore, they need to be replaced after a period of use. Current anesthetic waste gas purification devices usually require shutdown when replacing activated carbon and other adsorption materials, which is inconvenient and makes loading and unloading activated carbon materials quite troublesome.

[0004] Therefore, we propose a device for purifying and treating anesthetic waste gas in order to solve the problems mentioned above.

[0005] The information disclosed above in this background section is only for enhancing the understanding of the background section of this invention, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide an anesthetic waste gas purification and treatment device to solve the problems currently found in the market as described in the background.

[0007] To achieve the above objectives, this utility model provides an anesthetic waste gas purification and treatment device, including a lower box and an upper box disposed on the lower box. The lower box is provided with three partitions inside, and the partitions are provided with openings.

[0008] A work area is provided between the two upper partitions;

[0009] The work area is a cylindrical hollow structure with an arc-shaped notch. A rotating plate is installed in the work area. A placement cylinder is installed in the cavity formed by the work area and the rotating plate. An activated carbon adsorption layer is installed inside the placement cylinder. An air outlet is provided at the bottom of the placement cylinder.

[0010] The bottom of the work area is provided with a first filter plate that has the same shape as the opening of the partition and is located at the same position as the opening of the partition.

[0011] A motor is provided between the two lower partitions. The output shaft of the motor is connected to a rotating shaft, which passes through the working chamber and is fixed to the rotating plate.

[0012] The upper housing is provided with an air inlet and a fan located inside the upper housing. The lower housing is provided with a door and an air outlet located below the bottom partition.

[0013] Preferably, the rotating plate has a cross-shaped structure, and there are four chambers between the working area and the rotating plate, with a placement cylinder in each chamber.

[0014] Preferably, an air guide plate is fixedly installed between the two lower partitions, and the air guide plate is installed on the periphery of the partitions.

[0015] Preferably, the lower box and the upper box are fastened together by elastic buckles.

[0016] Preferably, the placement cylinder has a groove and is rotatably connected to a handle located in the groove.

[0017] Preferably, a second filter plate is also provided at the opening of the topmost partition.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] (1) This utility model divides the working room into multiple chambers by setting a rotating plate. Each chamber can hold an activated carbon adsorption layer. When one of the activated carbon adsorption layers in use fails, the activated carbon adsorption layer can be quickly replaced by controlling the rotation of the rotating plate. This allows the machine to work without stopping, and the replacement efficiency is high and convenient.

[0020] (2) This utility model makes it easy to remove the expired activated carbon adsorption layer and install a new activated carbon adsorption layer by providing a door on the lower box and a notch on the placement cylinder. It is simple to operate and easy to use.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.

[0034] Please see Figures 1-10An anesthetic waste gas purification and treatment device includes: a lower box 1 and an upper box 2 disposed on the lower box 1. The lower box 1 has three partitions 6 inside, and the partitions 6 have openings. A working chamber 8 is disposed between the two upper partitions 6. The working chamber 8 is a cylindrical hollow structure with an arc-shaped notch. A rotating plate 14 is disposed in the working chamber 8. A placement cylinder 9 is installed in the cavity formed by the working chamber 8 and the rotating plate 14. An activated carbon adsorption layer 18 is disposed inside the placement cylinder 9. An air outlet 10 is disposed at the bottom of the placement cylinder 9. A first filter plate 15 with the same shape as the opening of the partition 6 is disposed at the bottom of the working chamber 8 and is located at the same position as the opening of the partition 6. A motor 12 is disposed between the two lower partitions 6. The output shaft of the motor 12 is driven and connected to a rotating shaft 11. The rotating shaft 11 passes into the working chamber and is fixed to the rotating plate 14. The upper box 2 has an air inlet 4 and a fan 7 disposed inside the upper box 2. The lower box 1 has a door 3 and an air outlet 5 located below the bottom partition 6.

[0035] By adopting the above technical solution, when in use, an activated carbon adsorption layer 18 is placed in the placement cylinder 9, and then the placement cylinder 9 is controlled to rotate so that the activated carbon adsorption layer 18 is positioned between the openings of the partition 6. In this way, when the fan 7 works to draw in external air, it first passes through the opening of the uppermost partition 6, then through the activated carbon adsorption layer 18 to adsorb the anesthetic waste gas in the air, then through the air outlet 10 at the bottom of the placement cylinder 9, and then through the bottommost partition 6 before reaching the air outlet 5 for discharge. This can purify the air by adsorbing the anesthetic waste gas in the air.

[0036] The advantages of the above technical solution are: multiple activated carbon adsorption layers 18 can be placed to adsorb anesthetic waste gas, and the adsorption effect of the activated carbon adsorption layer 18 in use can be quickly replaced when it is significantly reduced. The placement cylinder 9 can be removed for cleaning. At the same time, the normal operation of the device is not affected when replacement is required.

[0037] The rotating plate 14 has a cross-shaped structure, and there are four chambers between the working chamber 8 and the rotating plate 14, and each chamber is equipped with a placement cylinder 9.

[0038] By adopting the above technical solution, the activated carbon adsorption layers 18 placed in the four chambers are respectively: the activated carbon adsorption layer 18 in use, the activated carbon adsorption layer 18 that has failed and is to be removed, the activated carbon adsorption layer 18 that needs to be removed, and the newly installed activated carbon adsorption layer 18. This allows the device to work continuously, is easy to clean, and has a spare activated carbon adsorption layer 18. If the activated carbon adsorption layer 18 in use is found to be ineffective, the spare activated carbon adsorption layer 18 can be activated immediately.

[0039] A guide plate 13 is fixedly installed between the two lower partitions 6. The guide plate 13 is installed on the periphery of the partition 6. The lower box 1 and the upper box 2 are fastened by elastic buckles 19. The placement cylinder 9 is provided with a groove and is rotatably connected to a handle 17 located in the groove. A second filter plate 16 is also provided at the opening of the top partition 6.

[0040] The lower housing 1 and the upper housing 2 are detachably connected, so that the fan 7 inside the upper housing 2 can be cleaned to prevent dust accumulation caused by long-term use. The elastic buckle 19 is a common structure in the prior art. The second filter plate 16 is used to filter dust in the air.

[0041] Example 2:

[0042] An improvement was made based on Example 1, wherein the arc-shaped surface of the placement cylinder 9 is at the same height as the notch of the working chamber 8, and the height of the contact surface with the rotating plate 14 is less than the height of its arc-shaped surface, which makes it easier to remove the activated carbon adsorption layer.

[0043] Working principle: When in use, the fan is started, so that the outside air passes through the air inlet 4, the second filter plate 16, the activated carbon adsorption layer 18, the air guide plate 13 in sequence, and finally leaves through the air outlet 5, so that the anesthetic waste gas is adsorbed. When the activated carbon adsorption layer 18 needs to be replaced, the motor 12 is controlled to rotate the rotating plate 14 ninety degrees, which completes the replacement of the activated carbon adsorption layer 18. Then, the box door 3 is opened, and the expired activated carbon adsorption layer 18 located at the gap in the working chamber 8 can be taken out.
