Description

Technical Field

[0001] This utility model relates to the field of exhaust gas adsorption technology, and in particular to an inert gas glove box exhaust gas adsorption device. Background Technology

[0002] Inert gas glove box exhaust gas typically refers to the waste gas produced when inert gases (such as argon, nitrogen, etc.) react with air or other reactive substances during operation inside the glove box, or the gas discharged after the internal gas is replaced. Because inert gases themselves do not react with most substances, their role in the glove box is to protect sensitive materials from the effects of oxygen, moisture, etc. However, air or other harmful substances inside the glove box may be discharged with the gas, becoming "exhaust gas". When these exhaust gases are directly released into the environment, they can affect the external environment or the health of operators, so adsorption equipment is needed for purification.

[0003] Chinese patent discloses an inert gas glove box tail gas adsorption tank (publication number CN222076215U). This patented technology enables the entire device to spray the adsorption liquid evenly, improving the effect of tail gas adsorption, enhancing the precision of tail gas treatment, and bringing better application prospects.

[0004] However, most existing inert gas glove box exhaust gas adsorption methods involve directly introducing the exhaust gas into the adsorption tank and spraying it. Due to the high fluidity of the exhaust gas, sufficient adsorption treatment cannot be achieved within the adsorption tank. For example, the aforementioned prior art uses a direct spraying method to achieve this. Therefore, those skilled in the art provide an inert gas glove box exhaust gas adsorption device to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an inert gas glove box exhaust gas adsorption device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an inert gas glove box tail gas adsorption device, including an adsorption tank, an inlet pipe disposed on one side of the adsorption tank, and an outlet pipe disposed on the upper surface of the adsorption tank. A filter cylinder is disposed at the upper end of the outlet pipe. A limit ring is disposed on the upper surface of the outlet pipe outside the filter cylinder, and an adsorption plate and a dehumidification plate are disposed inside the filter cylinder from top to bottom.

[0007] A speed-reducing mechanism is provided inside the adsorption tank near the outlet pipe. The speed-reducing mechanism includes a speed-reducing disc installed inside the adsorption tank, a positioning disc above the speed-reducing disc, a motor connected to the driving end of the positioning disc, a rotating shaft connected to the driving end of the motor, a turntable connected to the lower end of the rotating shaft, a first speed-reducing hole on the upper surface of the turntable, and a second speed-reducing hole on the upper surface of the speed-reducing disc.

[0008] As a further technical solution of this utility model, both the first deceleration hole and the second deceleration hole are circular holes, and the first deceleration hole and the second deceleration hole are correspondingly arranged.

[0009] As a further technical solution of this utility model, a liquid storage tank is provided on one side of the adsorption tank, a liquid pump is installed on the upper surface of the liquid storage tank, a drain pipe is connected to the outlet end of the liquid pump, a connecting pipe is connected to one side of the drain pipe, and a spray ring is connected to one end of the connecting pipe inside the adsorption tank.

[0010] As a further technical solution of this utility model, the filter cylinder is provided with an external thread on its outside, and the air outlet pipe is provided with an internal thread that engages with the external thread on its inside.

[0011] As a further technical solution of this utility model, two sets of positioning rings are also provided on the inner side of the filter cylinder, and the adsorption plate and the dehumidification plate are both installed with the two sets of positioning rings by bolts.

[0014] 1. This design provides an inert gas glove box tail gas adsorption device. The motor in the speed reduction mechanism operates, causing the turntable at the lower end of the rotating shaft to rotate on the speed reduction plate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution for an inert gas glove box exhaust gas adsorption device: it includes an adsorption tank 1, an inlet pipe 11 disposed on one side of the adsorption tank 1, and an outlet pipe 12 disposed on the upper surface of the adsorption tank 1. A filter cylinder 4 is disposed at the upper end of the outlet pipe 12. A limit ring 41 is disposed on the upper surface of the outlet pipe 12 outside the filter cylinder 4. An adsorption plate 42 and a dehumidification plate 43 are disposed inside the filter cylinder 4 from top to bottom. The adsorption plate 42 and the dehumidification plate 43 inside the filter cylinder 4 can be used to dehumidify and adsorb the exhaust gas, thus avoiding the exhaust gas from affecting the surrounding personnel or environment.

[0022] A speed reduction mechanism 3 is installed inside the adsorption tank 1 near the outlet pipe 12. The speed reduction mechanism 3 includes a speed reduction disk 34 installed inside the adsorption tank 1. A positioning disk 31 is installed above the speed reduction disk 34. A motor 32 is connected to the drive end of the positioning disk 31. A rotating shaft 321 is connected to the drive end of the motor 32. A turntable 33 is connected to the lower end of the rotating shaft 321. A first speed reduction hole 331 is opened on the upper surface of the turntable 33. A second speed reduction hole 341 is opened on the upper surface of the speed reduction disk 34. The operation of the motor 32 will cause the turntable 33 at the lower end of the rotating shaft 321 to rotate. When it rotates, the overlap between the first speed reduction hole 331 and the second speed reduction hole 341 can be adjusted, thereby reducing the flow rate of the exhaust gas. This can better achieve the purpose of adsorption treatment of the exhaust gas.

[0023] like Figure 3 As shown, both the first deceleration hole 331 and the second deceleration hole 341 are circular holes, and the first deceleration hole 331 and the second deceleration hole 341 are set in correspondence. The purpose of decelerating the incoming exhaust gas can be achieved by using the first deceleration hole 331 and the second deceleration hole 341, so as to avoid the exhaust gas flow rate being too fast and affecting its adsorption treatment work.

[0024] like Figure 1 As shown, a liquid storage tank 2 is provided on one side of the adsorption tank 1. A liquid pump is installed on the upper surface of the liquid storage tank 2. The outlet end of the liquid pump is connected to a drain pipe 21. A connecting pipe 22 is connected to one side of the drain pipe 21. One end of the connecting pipe 22 is connected to a spray ring 23 inside the adsorption tank 1. The liquid pump can draw liquid from the inside of the liquid storage tank 2 and enter the connecting pipe 22 through the drain pipe 21. Finally, it enters the spray ring 23 and is sprayed out through the spray holes to achieve the purpose of adsorption treatment.

[0025] like Figure 2 As shown, the filter cartridge 4 has an external thread on its outside and the air outlet pipe 12 has an internal thread that engages with the external thread on its inside. The filter cartridge 4 can be installed and disassembled through the threaded connection between the filter cartridge 4 and the air outlet pipe 12.

[0026] like Figure 2 As shown, two sets of positioning rings 44 are also provided on the inner side of the filter cylinder 4. The adsorption plate 42 and the dehumidification plate 43 are both installed with the two sets of positioning rings 44 by bolts. The material of the adsorption plate 42 is activated carbon, and the material of the dehumidification plate 43 is molecular sieve. The adsorption plate and the dehumidification plate can be used to dehumidify and adsorb the exhaust gas, which can prevent the exhaust gas from causing harm to the surrounding staff or environment.

[0027] The working principle of this utility model is as follows: When the inert gas glove box tail gas adsorption device of this utility model is used, the tail gas of the inert gas glove box is first extracted by an external air extraction device and enters the adsorption tank 1 through the air inlet pipe 11. When entering, the liquid pump on the liquid storage tank 2 can extract the liquid inside. After extraction, the liquid enters the spray ring 23 through the drain pipe 21 and the connecting pipe 22. Finally, it is sprayed out through the spray hole to contact the tail gas and achieve the purpose of adsorption treatment.

[0028] The treated exhaust gas will be decelerated by passing through the first deceleration hole 331 and the second deceleration hole 341, so that the exhaust gas can be better adsorbed and treated. By starting the motor 32, the turntable 33 connected to the lower end of the rotating shaft 321 will rotate, thus adjusting the overlap of the first deceleration hole 331 and the second deceleration hole 341 to achieve the purpose of deceleration.

[0029] After treatment, the exhaust gas will be discharged outward through the exhaust pipe 12. During discharge, it passes through the dehumidification plate 43 and the adsorption plate 42. The adsorption plate 42 and the dehumidification plate 43 can dehumidify and adsorb the discharged gas, thus avoiding the gas discharge from causing harm to the surrounding staff or environment. The dehumidification plate 43 and the adsorption plate 42 are installed inside the filter cylinder 4, and the filter cylinder 4 is threadedly connected to the exhaust pipe 12, which facilitates its disassembly and cleaning, and has good practicality.

[0030] All electrical devices used in this invention are existing and known, and are connected to an external main controller and power supply. The main controller can be a conventional and known device such as a computer, and can be purchased and used directly on the market. Its structure, circuit and control principle are all existing and known technologies. Therefore, the structure, circuit and control principle of the device are not described in detail here.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
