Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of air intake devices, and more specifically, relates to an air intake device and a gas-liquid phase reaction device. Background Art
[0002] Gas-liquid phase reaction units play a vital role in the chemical industry, being widely used in a variety of processes, including synthesis, catalysis, and extraction. These units achieve efficient conversion and product generation by precisely controlling the contact and reaction between gas and liquid. However, conventional gas-liquid phase reaction units often face a significant problem during operation: precipitates generated during the reaction process tend to accumulate in the inlet system, leading to blockage. When gas enters the reaction liquid through the inlet, if the reaction system contains components that are prone to precipitating, these components may rapidly precipitate due to factors such as localized high concentrations, temperature, or pressure fluctuations, forming solid particles. These particles, as the gas flows, continuously impact and adhere to surfaces of the inlet system, such as the nozzle, gas distribution plate, or the inner wall of the pipe. Over time, these deposits gradually thicken, eventually reducing the effective cross-sectional area of the inlet channel, restricting gas flow, or even completely blocking it.
[0003] Blockage in the gas inlet not only directly affects the uniform distribution and effective mass transfer of gas, significantly reducing reaction efficiency, but also potentially triggers side reactions due to imbalanced reaction conditions, further affecting the purity and quality of the final product. Furthermore, frequent blockages and cleanup increase operational complexity, shorten equipment life, increase maintenance costs, and threaten the continuous and stable operation of the entire production line. Utility Model Content
[0004] The purpose of the embodiments of the present application is to provide an air intake device and a gas-liquid phase reaction device to solve the technical problem in the prior art that the air intake device is easily blocked.
[0005] To achieve the above objectives, the technical solution adopted in this application is:
[0006] An air intake device is provided, comprising:
[0007] An outer shell having an air inlet and a sliding channel, wherein one end of the sliding channel is connected to the air inlet and the other end of the sliding channel is open;
[0008] a breathable member extending from the open portion into the sliding channel; the breathable member comprising a side wall portion and a bottom plate portion, one end of the side wall portion being an open end, and the bottom plate portion being connected to the other end of the side wall portion; the side wall portion extending from the open end to the bottom plate portion into the sliding channel, the side wall portion being slidably connected to the sliding channel; the side wall portion further comprising a plurality of breathable holes;
[0009] When gas is filled into the air inlet, the air permeable member extends outward from the sliding channel so that the filled gas is discharged to the outside through the air vents; when gas is not filled into the air inlet, the air permeable member is retracted into the sliding channel and the bottom plate is in sealing contact with the opening.
[0010] As a further improvement of the above technical solution:
[0011] Optionally, an elastic member is further included, one end of which is connected to the outer shell, and the other end is connected to the breathable member; when gas is injected into the air inlet, the breathable member extends outward from the sliding channel to stretch the elastic member; when gas is not injected into the air inlet, the elastic member contracts to retract the breathable member into the sliding channel.
[0012] Optionally, a first sealing member is provided on the bottom plate portion, and after the air-permeable member is retracted into the sliding channel, the first sealing member is in sealing contact with the opening.
[0013] Optionally, a second sealing member is further included, wherein the second sealing member is arranged between the outer shell and the side wall portion.
[0014] The present application also provides a gas-liquid phase reaction device, comprising the above-mentioned air intake device.
[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] The air intake device provided in the present application includes an outer shell and a breathable member. The outer shell has an air inlet and a sliding channel, one end of the sliding channel is connected to the air inlet, and the other end of the sliding channel is open. The breathable member extends from the open end into the sliding channel; the breathable member includes a side wall portion and a bottom plate portion, one end of the side wall portion is an open end, and the bottom plate portion is connected to the other end of the side wall portion; the side wall portion extends from the open end to the bottom plate portion into the sliding channel, and the side wall portion and the sliding channel are slidably connected; the side wall portion also has a plurality of breathable holes, through which the incoming gas is dispersed into fine bubbles, thereby increasing the contact area between the gas and the liquid and improving the gas dissolution efficiency.
[0017] In actual operation, when gas is introduced into the air inlet, the gas permeable element extends outward from the sliding channel under the influence of gas pressure. This allows gas to be discharged smoothly through the vents to the outside world, achieving effective gas release. When gas is no longer introduced into the air inlet, the gas permeable element retracts into the sliding channel under the influence of external force or a reset mechanism, bringing the bottom plate into close contact with the opening, forming an effective seal. This not only effectively isolates the vents in the gas permeable element from contact with the external environment, but also effectively prevents external sediment or particles from entering and clogging the vents, thereby ensuring the long-term stable operation of the air intake device.

[0035] like Figure 1 and Figure 3 As shown, the present application provides an air intake device, comprising an outer shell 1 and an air permeable member 2 .
[0036] The outer shell 1 has an air inlet 11 and a sliding channel 12. One end of the sliding channel 12 is connected to the air inlet 11, and the other end of the sliding channel 12 is an open end 13. The air permeable member 2 extends from the open end 13 into the sliding channel 12. The air permeable member 2 includes a side wall portion 21 and a bottom plate portion 22. One end of the side wall portion 21 is an open end 211, and the bottom plate portion 22 is connected to the other end of the side wall portion 21. The side wall portion 21 extends from the open end 211 to the bottom plate portion 22 into the sliding channel 12, and the side wall portion 21 and the sliding channel 12 are slidably connected. The side wall portion 21 also has a plurality of air holes 23. The air holes 23 disperse the incoming gas into fine bubbles, thereby increasing the contact area between the gas and the liquid and improving the gas dissolution efficiency.
[0037] In actual operation, when gas is introduced into the air inlet 11, the air permeable member 2 extends outward from the sliding channel 12 under the influence of the gas pressure. At this point, the gas can be smoothly discharged to the outside through the air holes 23, achieving effective gas release. When the air inlet 11 is no longer being introduced, the air permeable member 2 retracts into the sliding channel 12 under the influence of an external force or a reset mechanism, bringing the bottom plate 22 into close contact with the opening 13, forming an effective seal. This not only effectively isolates the air holes 23 in the air permeable member 2 from contact with the external environment, but also effectively prevents external sediment or particles from entering and clogging the air holes 23, thereby ensuring the long-term stable operation of the air intake device.
[0038] like Figure 1 and Figure 3 As shown, in a specific embodiment of the present application, the air intake device further includes an elastic member 3. One end of the elastic member 3 is connected to the outer shell 1, and the other end is connected to the air-permeable member 2.
[0039] When gas is introduced into the air inlet 11, the gas pressure drives the breathable member 2 to extend outward along the sliding channel 12. During this process, the displacement of the breathable member 2 causes the elastic member 3 to stretch, which in turn accumulates a certain amount of elastic potential energy. This not only ensures the smooth extension of the breathable member 2 and allows gas to be discharged smoothly through the air holes 23, but also provides the necessary power reserve for the subsequent reset of the breathable member 2.
[0040] When the air inlet 11 is no longer being filled with gas, the elastic potential energy previously stored in the elastic member 3 begins to release, driving the breathable member 2 to retract inward along the sliding channel 12. Under the contraction of the elastic member 3, the breathable member 2 is pulled back into the sliding channel 12 until the bottom plate portion 22 is in contact with the opening 13, forming an effective seal, effectively preventing foreign matter from entering the air vent 23 and ensuring the long-term stable operation of the air intake device.
[0041] The elastic member 3 may specifically be a spring.
[0042] like Figure 2 and Figure 4 As shown, in a specific embodiment of the present application, to further enhance the sealing performance of the air intake device when the air permeable member 2 is retracted, a first sealing member 4 is provided on the bottom plate portion 22. Specifically, when the air permeable member 2 is retracted into the sliding channel 12 under the action of the elastic member 3, the first sealing member 4 approaches and eventually contacts the opening 13. This sealed contact not only effectively prevents impurities, moisture, or gas from the external environment from infiltrating into the sliding channel 12 through the opening 13, but also ensures that the air holes 23 in the air permeable member 2 are completely isolated from the outside world when not in operation, thereby effectively avoiding the risk of air holes 23 becoming clogged.
[0043] like Figure 2 and Figure 4 As shown, in a specific embodiment of the present application, to further optimize the sealing performance of the air intake device, the air intake device also includes a second sealing member 5. Specifically, the second sealing member 5 is disposed between the outer shell 1 and the sidewall portion 21, effectively filling any small gap that may exist between the outer shell 1 and the sidewall portion 21, thereby enhancing the sealing between the two. When the air-permeable member 2 telescopes along the sliding channel 12, the second sealing member 5 ensures that the contact surface between the sidewall portion 21 and the outer shell 1 always maintains a tight and stable seal, effectively preventing gas or liquid leakage.
[0044] The present application also provides a gas-liquid phase reaction device, which includes the air intake device in the above embodiment, and therefore also has the advantages of the air intake device in the above embodiment.
[0045] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
