Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gas-liquid separation, in particular to a gas-liquid separator. BACKGROUND

[0002] In the development of anode conventional tank liquid, dyeing tank dyeing liquid automatic analysis project, the sample of the liquid to be measured needs to be extracted, but due to the air stirring technology used in each tank, a large amount of air will be mixed into the sample of the liquid to be measured when the sample is extracted, forming a gas-liquid mixture, and the mixing of air will eventually affect the accuracy of the analysis results. In order to solve the above problem, a gas-liquid separator is used in the process of obtaining the sample of the liquid to be measured. The gas-liquid separator is generally provided with an automatic exhaust valve to realize the exhaust of air in the sample of the liquid to be measured.

[0003] At present, the gas-liquid separator includes a containing part and an automatic exhaust valve, the containing part is used for introducing the gas-liquid mixture, the containing part has an exhaust port, and the automatic exhaust valve is arranged at the exhaust port. The automatic exhaust valve is generally provided with a mounting shell, a floating element and a valve rod. The mounting shell is in communication with the containing part, so that the gas-liquid mixture flows into the mounting shell. The floating element is arranged in the mounting shell and connected with the valve rod. According to the change of the liquid level of the gas-liquid mixture, the floating element is driven to float, so as to drive the valve rod to move through the movement of the floating element, so as to open or close the exhaust port. It can be seen that the structure of the automatic exhaust valve in the above setting is relatively complex, thereby leading to the complex structure of the gas-liquid separator. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the present application provides a gas-liquid separator which can simplify the structure of the gas-liquid separator and reduce the cost of the gas-liquid separator.

[0005] The embodiment of the present application provides a gas-liquid separator, which includes a containing part, a liquid outlet pipe, an exhaust pipe and a floating element. The containing part has a closed containing space, and the containing space is used for introducing a gas-liquid mixture. The liquid outlet pipe is connected with the containing part, and the liquid outlet pipe has a liquid outlet inlet. The liquid outlet inlet is located in the containing space and in communication with the containing space. The exhaust pipe is connected with the containing part, and at least part of the exhaust pipe is located in the containing space. The exhaust pipe is provided with a communication port and an exhaust port in communication. The communication port is in communication with the containing space, and the exhaust port is used for communication with the external environment. The floating element is connected with the exhaust pipe, and the floating element has a shielding position and an avoiding position. When the floating element is in the shielding position, the floating element shields the liquid outlet inlet of the liquid outlet pipe. When the floating element is in the avoiding position, the floating element is separated from the liquid outlet inlet of the liquid outlet pipe.

[0006] When the accommodating component is filled with the gas-liquid mixture and the floating member has not floated, the floating member is in the shielding position, and the shielding effect of the floating member can improve the problem that the bubbles in the gas-liquid mixture flow out through the liquid outlet pipe before being discharged through the air outlet pipe. When the floating member floats to a position separated from the liquid outlet inlet of the liquid outlet pipe, the floating member is in the avoiding position. Since the air is lighter in mass and a certain amount of gas-liquid mixture is collected in the accommodating component, the air in the gas-liquid mixture collected in the accommodating component is gathered above the liquid in the accommodating component, and the air in the gas-liquid mixture is discharged through the communication opening and the air outlet of the air outlet pipe, and the liquid is discharged through the liquid outlet pipe, so that the gas-liquid separation is realized. It can be seen that the gas-liquid separator of the application realizes the gas-liquid separation by the cooperation of the floating member with the liquid outlet pipe and the air outlet pipe. Compared with the automatic air discharge valve of the related art gas-liquid separator, the gas-liquid separator of the application does not need to additionally provide a valve rod and a mounting shell, so that the structure of the gas-liquid separator is simplified, the cost is reduced, and since the gas-liquid separator of the application does not provide a valve rod, the problem that the valve rod of the automatic air discharge valve of the related art is easily worn can be avoided. Moreover, the floating member changes the floating position according to the change of the liquid level, and the floating member is connected with the air outlet pipe and relatively moves with respect to the air outlet pipe, so that the floating member and the air outlet pipe are movably connected, the floating member is not easily deformed and worn, and the service life of the gas-liquid separator is improved.

[0007] In at least one embodiment, the air outlet pipe is movably arranged in the accommodating component, and the air outlet pipe is fixedly connected with the floating member so that the floating member and the air outlet pipe float simultaneously.

[0008] During the process of filling the accommodating component with liquid, as the liquid level increases, the air outlet pipe and the floating member gradually float upward, so that the communication opening on the air outlet pipe gradually moves to the outside of the accommodating component, until the communication opening is completely located outside the accommodating component, the gas in the accommodating space of the accommodating component is completely discharged, at this time, the floating member is still located in the accommodating component, and the floating member blocks the gap between the accommodating component and the air outlet pipe, so that the liquid is not easily discharged from the gap between the accommodating component and the air outlet pipe.

[0009] In at least one embodiment, the air outlet pipe comprises an air outlet pipe segment and a solid pipe segment. The air outlet pipe segment has an air outlet pipe cavity, and the communication opening and the air outlet are arranged on the air outlet pipe segment and communicate with the air outlet pipe cavity. The solid pipe segment is connected with the air outlet pipe segment and located on the side of the air outlet pipe segment close to the liquid outlet pipe, and the floating member is fixedly connected with the solid pipe segment.

[0010] When the floating element is in the shielding position, the floating element is connected with the solid pipe segment and the liquid outlet pipe respectively, at this time, the gas-liquid mixture in the containing space has not yet entered the exhaust pipe cavity of the exhaust pipe segment, so that the liquid surface of the gas-liquid mixture is spaced apart from the communication port, so that the bubbles in the gas-liquid mixture extrude the wall of the solid pipe segment, so that the air in the bubbles is exposed at the remaining space of the containing space; and when the solid pipe segment and the floating element of the exhaust pipe are both floated to the top of the containing member, the solid pipe segment is provided through the containing member, and the floating element abuts against the containing member, so as to realize the sealing of the containing space through the solid pipe segment and the floating element, thereby improving the condition that the liquid is easily leaked between the containing member and the exhaust pipe.

[0011] In at least one embodiment, the exhaust port is located at the end of the exhaust pipe segment, and the communication port is provided on the wall of the exhaust pipe segment; wherein the length of the communication port extends from the solid pipe segment to the end face where the exhaust port is located.

[0012] The length of the communication port extends from the solid pipe segment to the end face where the exhaust port is located, so that the communication port is in communication with the external environment, thereby realizing that both the communication port and the exhaust port are in communication with the external environment, improving the exhaust area of the exhaust pipe, and thereby improving the problem that the undissolved solids in the gas-liquid mixture easily block the communication hole, and improving the exhaust effect of the exhaust pipe.

[0013] In at least one embodiment, the exhaust pipe is fixedly connected with the containing member, and the floating element is a cylindrical structure movably sleeved on the exhaust pipe; wherein when the cylindrical structure is in the shielding position, the two ends of the cylindrical structure are sleeved on the first liquid outlet pipe segment and the exhaust pipe respectively.

[0014] Since the cylindrical structure (floating element) is movably sleeved on the exhaust pipe, the inner wall surface of the cylindrical structure can be spaced apart from the outer wall surface of the first liquid outlet pipe segment and the outer wall surface of the exhaust pipe, so as to reduce the wear problem between the floating element and the liquid outlet pipe and the exhaust pipe, and improve the service life of the gas-liquid separator. Moreover, by arranging the floating element as a cylindrical structure, the cylindrical structure is sleeved on the liquid outlet pipe when the floating element is in the shielding position, so that the floating element surrounds the liquid outlet inlet of the liquid outlet pipe, so that the floating element can better shield the liquid outlet inlet of the liquid outlet pipe.

[0015] In at least one embodiment, the floating element has a first hole segment and a second hole segment, the first hole segment and the second hole segment are in communication, the hole inner diameter of the first hole segment is greater than the hole inner diameter of the second hole segment, so as to form a stop step between the first hole segment and the second hole segment; the exhaust pipe comprises a first exhaust pipe segment, a second exhaust pipe segment and a third exhaust pipe segment connected in sequence, the pipe diameter of the third exhaust pipe segment is greater than the pipe diameter of the first exhaust pipe segment, the pipe diameter of the second exhaust pipe segment gradually increases along the distribution direction from the first exhaust pipe segment to the third exhaust pipe segment, and the communication port is provided on the second exhaust pipe segment, so that when the floating element moves to the communication port, the stop step blocks the communication port.

[0016] The communication port is blocked by the stop step, which can improve the problem that liquid is easily sprayed from the communication port and the exhaust port of the exhaust pipe during the liquid inlet process, so that the liquid flows out through the liquid outlet of the liquid outlet pipe, and the gas-liquid separation effect and safety of the gas-liquid separator are improved.

[0017] In at least one embodiment, the exhaust pipe comprises a first exhaust pipe section and a second exhaust pipe section, the first exhaust pipe section and the second exhaust pipe section are communicated, the pipe diameter of the first exhaust pipe section is larger than that of the second exhaust pipe section, and the communication port is arranged on the end face of the first exhaust pipe section close to one end of the second exhaust pipe section, so that when the floating element moves to the communication port due to the buoyancy, the end face of the floating element blocks the communication port.

[0018] The communication port is arranged on the end face of the first exhaust pipe section close to one end of the second exhaust pipe section, so that when the floating element floats to the communication port with the increase of the liquid level in the containing member, the end face of the floating element can block the communication port, thereby improving the problem that liquid is easily sprayed from the communication port and the exhaust port of the exhaust pipe during the liquid inlet process, so that the liquid flows out through the liquid outlet of the liquid outlet pipe, and the gas-liquid separation effect and safety of the gas-liquid separator are improved.

[0019] In at least one embodiment, the gas-liquid separator further comprises a liquid inlet pipe for introducing liquid, the liquid inlet pipe is arranged in the containing member, and the liquid inlet pipe is arranged spaced apart from the liquid outlet pipe.

[0020] The liquid inlet pipe and the liquid outlet pipe are arranged spaced apart, so that during the liquid inlet process of the liquid inlet pipe, liquid is introduced to the side of the liquid inlet pipe facing the liquid outlet pipe, thereby improving the situation that the gas-liquid mixture flows out through the gap between the liquid outlet pipe and the floating element before the gas is discharged.

[0021] In at least one embodiment, the liquid inlet pipe has a liquid inlet outlet located in the containing space; wherein: the liquid inlet outlet and the liquid outlet inlet are located at the same position in the length direction of the containing member; or the liquid inlet outlet is located on the side of the liquid outlet inlet close to the bottom of the containing member.

[0022] During the liquid inlet process of the liquid inlet pipe, the gas-liquid mixture may splash, the liquid inlet outlet and the liquid outlet inlet are located at the same position in the length direction of the containing member, or the liquid inlet outlet is arranged on the side of the liquid outlet inlet close to the bottom of the containing member, so that the distance between the liquid inlet outlet and the bottom of the containing member is small, thereby improving the situation that part of the liquid flows out through the liquid outlet inlet of the liquid outlet pipe before the gas is discharged due to the splashing of the gas-liquid mixture.

[0023] In at least one embodiment, the containing member comprises a containing bin and a cover plate, the liquid outlet pipe is connected to the containing bin and located at the bottom of the containing bin; the cover plate is located above the liquid outlet pipe and detachably connected to the containing bin, the cover plate and the containing bin enclose a containing space, and the exhaust pipe is arranged in and connected to the cover plate.

[0024] The cover plate is detachably connected with the containing bin, so that the cover plate and the containing bin can be separated after use of the gas-liquid separator, facilitating cleaning of the inside of the containing bin.

[0025] In at least one embodiment, the containing bin has a containing cavity and a containing opening in communication, the cover plate is arranged in the containing cavity, and a spillway is formed between the cover plate and the containing opening, and the exhaust port and / or the communication port of the exhaust pipe are located in the spillway.

[0026] During use of the gas-liquid separator, if liquid and deposits are accumulated in the spillway, the liquid and the deposits can flow back into the containing part through the communication port / exhaust port, so as to improve the problem of easy leakage of liquid and deposits of the exhaust valve, and improve the use safety of the gas-liquid separator.

[0027] In at least one embodiment, the cover plate comprises a plate body and a sleeve part, the plate body covers the containing bin, the sleeve part is fixedly connected with the plate body and located in the containing space, and the exhaust pipe is arranged through the plate body and the sleeve part.

[0040] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all embodiments of the present application.

[0041] In the related art, the gas-liquid separator includes a containing component for containing liquid, and an automatic exhaust valve. The containing component has an exhaust port, and the automatic exhaust valve is arranged at the exhaust port. The automatic exhaust valve generally has a mounting shell, a floating member, and a valve rod. The mounting shell is in communication with the containing component to allow the gas-liquid mixture to flow into the mounting shell. The floating member is arranged in the mounting shell and is connected with the valve rod. According to the change of the liquid level of the gas-liquid mixture, the floating member is floated to drive the valve rod to move to open or close the exhaust port through the movement of the floating member. It can be seen that the structure of the automatic exhaust valve in the above arrangement is relatively complex, thereby leading to the complex structure of the gas-liquid separator. Specifically, the mounting shell of the automatic exhaust valve is located outside the containing component. The valve rod includes a spring pipe and an inner pipe. The side wall of the spring pipe is provided with a communication hole in communication with the outside. The inner pipe includes a first pipe segment and a second pipe segment. The spring pipe is sleeved on the first pipe segment and the second pipe segment. The first pipe segment and the second pipe segment are movably connected. Part of the first pipe segment is located in the mounting shell and is connected with the floating member to drive the first pipe segment to move relative to the second pipe segment through the movement of the floating member to have an exhaust position in communication with the communication hole and an isolation position separated from the outside between the first pipe segment and the second pipe segment. It can be seen that the structure of the automatic exhaust valve is relatively complex. If the automatic exhaust valve is applied to the gas-liquid separator, it will lead to the complex structure of the gas-liquid separator, increase the cost of the gas-liquid separator, and in the process of using the automatic exhaust valve, the connection between the pipe wall of the spring pipe, the first pipe segment, and the second pipe segment needs to be repeatedly moved, so that the valve rod is prone to deformation, thereby leading to the short service life of the automatic exhaust valve, and further leading to the short service life of the gas-liquid separator.

[0042] In an embodiment of the present application, the gas-liquid separator includes a containing component, a liquid outlet pipe, an exhaust pipe, and a floating member. The containing component is used to contain liquid. The liquid outlet pipe is in communication with the containing component. At least part of the exhaust pipe is located in the containing space. The exhaust pipe is provided with a communication port and an exhaust port in communication with each other. The communication port is in communication with the containing space. The exhaust port is used to communicate with the outside environment to discharge the gas bubbles in the liquid in the containing component to the outside environment through the communication port and the exhaust port. The floating member is connected with the exhaust pipe and moves relatively with respect to the exhaust pipe. The floating member has a shielding position and an avoiding position. When the floating member is in the shielding position, the floating member shields the liquid outlet inlet of the liquid outlet pipe. When the floating member is in the avoiding position, the floating member opens the liquid outlet inlet of the liquid outlet pipe.

[0043] When the accommodating component is filled with the gas-liquid mixture and the floating member has not floated, the floating member is in the shielding position, and the shielding effect of the floating member can improve the problem that the bubbles in the gas-liquid mixture flow out through the liquid outlet pipe before being discharged through the air outlet pipe. When the floating member floats to a position separated from the liquid outlet inlet of the liquid outlet pipe, the floating member is in the avoiding position. Because the air is lighter in mass and a certain amount of gas-liquid mixture is collected in the accommodating component, the air in the gas-liquid mixture collected in the accommodating component is gathered above the liquid in the accommodating component, and the air in the gas-liquid mixture is discharged through the communication port 300 and the air outlet 301 of the air outlet pipe, and the liquid is discharged through the liquid outlet pipe, so that the gas-liquid separation is realized. It can be seen that the gas-liquid separator of the present application realizes the gas-liquid separation by the cooperation of the floating member with the liquid outlet pipe and the air outlet pipe. Compared with the automatic air discharge valve of the related art gas-liquid separator, the gas-liquid separator of the present application does not need to additionally provide a valve rod and a mounting shell, so that the structure of the gas-liquid separator is simplified, the cost is reduced, and the problem that the valve rod of the automatic air discharge valve of the related art is easily abraded can be avoided. In addition, the floating member of the present application changes the floating position according to the change of the liquid level, and the floating member is connected with the air outlet pipe and relatively moves with respect to the air outlet pipe, so that the floating member is movably connected with the air outlet pipe, the floating member is not easily deformed and abraded, and the service life of the gas-liquid separator is improved.

[0044] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The features in the following embodiments and examples can be combined with each other without conflict.

[0045] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, a gas-liquid separator is provided, which comprises an accommodating component 10, a liquid outlet pipe 20, an air outlet pipe 30 and a floating member 40.

[0046] In some embodiments, the accommodating component 10 has a closed accommodating space 100 for filling the gas-liquid mixture; the liquid outlet pipe 20 is connected with the accommodating component 10, and the liquid outlet pipe 20 has a liquid outlet inlet 200 located in the accommodating space 100 and in communication with the accommodating space 100; the air outlet pipe 30 is connected to the accommodating component 10, and at least part of the air outlet pipe 30 is located in the accommodating space 100. The air outlet pipe 30 is provided with a communication port 300 in communication with the accommodating space 100 and an air outlet 301 for communicating with the external environment, so that the air in the liquid in the accommodating space 100 is sequentially discharged to the external environment through the communication port 300 and the air outlet 301.

[0047] Please refer to Figure 2 and Figure 3In some embodiments, the floating member 40 is connected with the exhaust pipe 30. The floating member 40 changes the floating position of the whole floating member 40 according to the change of the liquid level of the gas-liquid mixture in the containing space 100. The floating member 40 is not prone to deformation and wear, thereby improving the problems of easy wear of the automatic exhaust valve of the gas-liquid separator in the prior art and low service life of the gas-liquid separator.

[0048] Please refer to Figure 2 and Figure 3 The floating member 40 has a shielding position and an avoiding position. When the floating member 40 is in the shielding position, the floating member 40 shields the liquid outlet inlet 200 of the liquid outlet pipe 20. When the floating member 40 is in the avoiding position, the floating member 40 is separated from the liquid outlet inlet 200 of the liquid outlet pipe 20.

[0049] After the containing member 10 is filled with liquid, the floating member 40 has not floated yet. When the floating member 40 is in the shielding position, the shielding effect of the floating member 40 can improve the problem that the gas bubbles in the gas-liquid mixture flow out through the liquid outlet pipe 20 before being discharged through the exhaust pipe 30.

[0050] When the floating member 40 floats to a position separated from the liquid outlet inlet 200 of the liquid outlet pipe 20, the floating member 40 is in the avoiding position. Since the air is lighter in mass and a certain amount of liquid is collected in the containing space 100, the air in the gas-liquid mixture filled in the containing space 100 is gathered above the gas-liquid mixture in the containing space 100. The air in the gas-liquid mixture is discharged through the communication opening 300 and the exhaust opening 301 of the exhaust pipe 30, and the liquid is discharged through the liquid outlet pipe 20, thereby realizing gas-liquid separation.

[0051] The gas-liquid separator of the present application realizes gas-liquid separation by the cooperation of the floating member 40 with the liquid outlet pipe 20 and the exhaust pipe 30. Compared with the automatic exhaust valve of the gas-liquid separator in the prior art, the gas-liquid separator of the present application does not need to additionally provide a valve rod and a mounting shell, thereby simplifying the structure of the gas-liquid separator and reducing the cost. Since the gas-liquid separator of the present application does not provide a valve rod, the problem of easy wear of the valve rod of the automatic exhaust valve in the prior art can be avoided.

[0052] Please refer to Figure 2 and Figure 3 In some embodiments, the exhaust pipe 30 includes an exhaust pipe segment 31 and a solid pipe segment 32. The exhaust pipe segment 31 has an exhaust pipe cavity. The communication opening 300 and the exhaust opening 301 are arranged on the exhaust pipe segment 31 and communicate with the exhaust pipe cavity. The solid pipe segment 32 is connected with the exhaust pipe segment 31 and located on the side of the exhaust pipe segment 31 close to the liquid outlet pipe 20.

[0053] When the float 40 is in the shielding position, the float 40 is connected with the solid pipe segment 32 and the liquid outlet pipe 20 respectively, at this time, the gas-liquid mixture in the containing space 100 has not yet entered the exhaust pipe cavity of the exhaust pipe segment 31, so that the liquid level of the gas-liquid mixture is spaced apart from the communication port 300, so that the bubbles in the gas-liquid mixture extrude the pipe wall of the solid pipe segment, and the air in the bubbles is exposed at the remaining space of the containing space.

[0054] In the related art, the liquid sample (gas-liquid mixture) to be measured contains powdery undissolved solids, the communication hole of the conventional automatic exhaust valve is small, and the powdery undissolved solids are easy to block the communication hole of the automatic exhaust valve, thereby affecting the exhaust effect.

[0055] Please refer to Figure 2 and Figure 3 In some embodiments, the exhaust port 301 is located at the end of the exhaust pipe segment 31, and the communication port 300 is arranged on the pipe wall of the exhaust pipe segment 31; wherein the length of the communication port 300 extends from the solid pipe segment 32 to the end face where the exhaust port 301 is located, so that the communication port 300 is in communication with the external environment, thereby realizing that the communication port 300 and the exhaust port 301 are both in communication with the external environment, improving the exhaust area of the exhaust pipe 30, thereby improving the problem that the undissolved solids in the gas-liquid mixture are easy to block the communication hole, and improving the exhaust effect of the exhaust pipe 30.

[0056] Please refer to Figure 2 and Figure 3 In some embodiments, the liquid outlet pipe 20 comprises a first liquid outlet pipe segment 21, and the first liquid outlet pipe segment 21 is located in the containing space 100, and the first liquid outlet pipe segment 21 has a liquid outlet inlet 200, and the liquid outlet inlet 200 is spaced apart from the bottom of the containing member 10.

[0057] If the liquid outlet inlet 200 of the liquid outlet pipe 20 is arranged flush with the bottom of the containing member 10, during the liquid inlet process of the containing member 10, the liquid is easy to flow out through the gap between the liquid outlet inlet 200 and the float 40 before the gas is discharged, thereby affecting the gas-liquid separation quality of the gas-liquid separator. In the present application, the first liquid outlet pipe segment 21 of the liquid outlet pipe 20 is arranged in the containing space 100, and when the liquid level is lower than the liquid outlet inlet 200 during the liquid inlet process of the containing member 10, the liquid outlet inlet 200 of the liquid outlet pipe 20 is shielded by the float 40, so that the liquid is not easy to flow out through the gap between the liquid outlet inlet 200 and the float 40, thereby improving the gas-liquid separation quality of the gas-liquid separator.

[0058] Please refer to Figure 2 and Figure 3 In some embodiments, the containing member 10 has a containing bin 11, and the liquid outlet outlet 220 of the liquid outlet pipe 20 is arranged at the lower end face of the containing bin 11 of the containing member 10.

[0059] Referring to Figure 2 and Figure 3 In some embodiments, the liquid outlet pipe 20 comprises a second liquid outlet pipe section 22 fixedly connected to the first liquid outlet pipe section 21 and located outside the containing space 100, and the second liquid outlet pipe section 22 has a liquid outlet 220 for flowing out the liquid after gas-liquid separation.

[0060] Referring to Figure 2 and Figure 3 In some embodiments, the gas-liquid separator further comprises a liquid inlet pipe 50 for introducing the gas-liquid mixture, the liquid inlet pipe 50 is arranged in the containing member 10, and the liquid inlet pipe 50 is arranged apart from the liquid outlet pipe 20 so that, during the process of liquid inlet by the liquid inlet pipe 50, the liquid inlet pipe 50 introduces liquid to the side of the liquid outlet pipe 20, thereby improving the situation that the gas-liquid mixture flows out through the gap between the liquid outlet pipe 20 and the floating member 40 before the gas is discharged.

[0061] Referring to Figure 2 and Figure 3 In some embodiments, the liquid inlet pipe 50 has a first liquid inlet pipe section 51 located in the containing space 100, and the first liquid inlet pipe section 51 is provided with a liquid inlet outlet 500.

[0062] Referring to Figure 2 and Figure 3 In some embodiments, the liquid inlet pipe 50 has a liquid inlet outlet 500 located in the containing space 100, and the liquid inlet outlet 500 and the liquid outlet inlet 200 are located at the same position in the length direction of the containing member 10. During the process of liquid inlet by the liquid inlet pipe 50, the gas-liquid mixture may splash, and by locating the liquid inlet outlet 500 and the liquid outlet inlet 200 at the same position in the length direction of the containing member 10, the distance between the liquid inlet outlet 500 and the bottom of the containing member 10 is small, thereby improving the situation that part of the liquid flows out through the liquid outlet inlet 200 of the liquid outlet pipe 20 before the gas is discharged due to the splashing of the gas-liquid mixture.

[0063] Referring to Figure 2 and Figure 3 In some embodiments, the liquid inlet pipe 50 has a liquid inlet outlet 500 located in the containing space 100, and the liquid inlet outlet 500 is located on the side of the liquid outlet inlet 200 close to the bottom of the containing member 10, so that the distance between the liquid inlet outlet 500 and the bottom of the containing member 10 is small, thereby improving the situation that part of the gas-liquid mixture flows out through the liquid outlet inlet 200 of the liquid outlet pipe 20 before the gas is discharged due to the splashing of the gas-liquid mixture.

[0064] Referring to Figure 2 and Figure 3In some embodiments, the containing component 10 comprises a containing bin 11 and a cover plate 12, the liquid outlet pipe 20 is connected with the containing bin 11 and located at the bottom of the containing bin 11; the cover plate 12 is located above the liquid outlet pipe 20 and detachably connected with the containing bin 11. After the gas-liquid separator is used, the cover plate 12 and the containing bin 11 can be separated to facilitate the cleaning of the inside of the containing bin 11.

[0065] Specifically, the cover plate 12 and the containing bin 11 enclose a containing space 100, and the exhaust pipe 30 penetrates through and is connected with the cover plate 12.

[0066] In the related art, the automatic exhaust valve has no anti-leakage design. If the gas-liquid separator is applied to strong acid liquid or strong alkali liquid, in the use process of the gas-liquid separator, if the strong acid liquid / strong alkali liquid overflows, it will cause harm to the operator.

[0067] Please refer to Figure 2 and Figure 3 In some embodiments, the containing bin 11 has a containing cavity and a containing opening 111, the containing cavity and the containing opening 111 are communicated, the cover plate 12 is arranged in the containing cavity, the overflow groove 112 is formed between the cover plate 12 and the containing opening 111, and the exhaust port 301 and / or the communication port 300 of the exhaust pipe 30 are located in the overflow groove 112. In the use process of the gas-liquid separator, if liquid and deposits are accumulated in the overflow groove 112, the liquid and the deposits will flow back to the containing component 10 through the communication port 300 / exhaust port 301, so as to improve the problem that the exhaust valve is easy to leak liquid and deposits and improve the use safety of the gas-liquid separator.

[0068] Please refer to Figure 2 and Figure 3 In some embodiments, the cover plate 12 comprises a plate body 120 and a sleeve part 121, the plate body 120 is arranged on the containing bin 11; the sleeve part 121 is fixedly connected with the plate body 120 and located in the containing space 100, and the exhaust pipe 30 penetrates through the plate body 120 and the sleeve part 121.

[0069] The connection area between the inner wall surface of the sleeve part 121 and the outer wall surface of the exhaust pipe 30 is large, so as to improve the stability of the connection between the cover plate 12 and the exhaust pipe 30; and when the exhaust pipe 30 moves relative to the cover plate 12, the sleeve part 121 can guide the exhaust pipe 30 to move stably.

[0070] In some embodiments, the exhaust pipe 30 is fixedly connected with the floating piece 40, and the exhaust pipe 30 and the floating piece 40 can float simultaneously.

[0071] In some embodiments, the floating member 40 is fixedly connected with the solid pipe segment 32 of the exhaust pipe 30, and when the solid pipe segment 32 of the exhaust pipe 30 and the floating member 40 are both floated to the sleeve portion 121, the floating member 40 abuts against the sleeve portion 121 through the solid pipe segment 32 penetrating the sleeve portion 121, so that the sealing of the containing space is realized through the solid pipe segment 32 and the floating member 40, thereby improving the leakage of liquid between the sleeve portion 121 and the exhaust pipe 30.

[0072] In some embodiments, the floating member 40 is a solid block structure, and the solid block structure is fixedly connected with the solid pipe segment 32 of the exhaust pipe 30, and when the floating member 40 is in the shielding position, the solid block structure blocks the liquid outlet inlet 200 of the first liquid outlet pipe segment 21.

[0073] Optionally, the solid block structure is in a cylindrical or spherical shape.

[0074] In some embodiments, the floating member 40 is fixedly connected with the exhaust pipe 30, and the floating member 40 is a cylindrical structure, and the cylindrical structure is internally provided with a partition plate, so that the cylindrical structure has a first connecting groove and a second connecting groove, and when the floating member 40 is in the shielding position, the liquid outlet inlet 200 of the liquid outlet pipe 20 is located in the first connecting groove, and one end of the exhaust pipe 30 is located in the second connecting groove and connected with the partition plate, so that the position between the floating member 40 and the exhaust pipe 30 is relatively fixed through the action of the partition plate during the floating of the floating member 40, thereby driving the exhaust pipe 30 to float.

[0075] Optionally, the circumferential side wall of the exhaust pipe 30 is in interference fit with the inner side wall of the second connecting groove.

[0076] Optionally, the exhaust pipe 30 and the partition plate can have the following connection modes: one end of the exhaust pipe 30 is bonded with the partition plate; or one end of the exhaust pipe 30 abuts against the partition plate; or one end of the exhaust pipe 30 is integrally fused or welded with the partition plate.

[0077] In some embodiments, the exhaust pipe 30 is fixedly connected with the cover plate 12 of the containing member 10, and the floating member is a cylindrical structure, and the floating member 40 is movably sleeved on the exhaust pipe 30, so that the floating member 40 moves relative to the exhaust pipe 30; wherein when the floating member 40 is in the shielding position, two ends of the cylindrical structure are sleeved on the liquid outlet pipe 20 and the exhaust pipe 30, respectively.

[0078] Specifically, the cylindrical structure has a through hole, so that the through hole of the cylindrical structure (the floating member 40) is movably sleeved on the exhaust pipe 30, so that the floating member 40 of the cylindrical structure can be individually floated to the sleeve portion 121.

[0079] Since the floating member 40 is movable, the inner wall surface of the cylindrical structure can be spaced apart from the outer wall surface of the first liquid outlet pipe section 21 and the outer wall surface of the exhaust pipe 30, so as to improve the wear problem between the floating member 40 and the first liquid outlet pipe section 21 and the exhaust pipe 30, and improve the service life of the gas-liquid separator. By arranging the floating member 40 in a cylindrical structure, the cylindrical structure is sleeved on the liquid outlet pipe 20, so that the cylindrical structure surrounds the liquid outlet pipe 20, so that when the floating member 40 is in the shielding position, the cylindrical structure can better shield the liquid outlet inlet 200 of the liquid outlet pipe 20.

[0080] In the use process of the gas-liquid separator, when the liquid level in the containing part reaches a certain height, if the inner wall surface of the cylindrical structure (the floating member 40) and the outer wall surface of the first liquid outlet pipe section 21 and the outer wall surface of the exhaust pipe 30 are always kept in a spaced apart state, the liquid is easy to flow into the communication port 300 through the gap between the outer wall surface of the first liquid outlet pipe section 21 and the outer wall surface of the exhaust pipe 30, thereby spraying liquid from the exhaust port 301 of the exhaust pipe 30, if the gas-liquid separator is used for gas-liquid separation of chemical reagents, the liquid sprayed from the exhaust port 301 of the exhaust pipe 30 is easy to hurt the operator, and the safety is poor.

[0081] Please refer to Figure 4 and Figure 5 In some embodiments, the through hole of the cylindrical structure (the floating member 40) includes a first hole section 401 and a second hole section 402, the first hole section 401 and the second hole section 402 are communicated, the hole inner diameter of the first hole section 401 is greater than the hole inner diameter of the second hole section 402, so as to form a stop step 41 between the first hole section 401 and the second hole section 402; the exhaust pipe 30 includes a first exhaust pipe section 311, a second exhaust pipe section 312 and a third exhaust pipe section 313 connected in sequence, the pipe diameter of the third exhaust pipe section 313 is greater than the pipe diameter of the first exhaust pipe section 311, the second exhaust pipe section 312 is a variable diameter pipe section, the pipe diameter of the second exhaust pipe section 312 gradually increases along the distribution direction of the first exhaust pipe section 311 to the third exhaust pipe section 313, and the communication port 300 is arranged on the second exhaust pipe section 312, so that when the floating member 40 moves to the communication port 300 due to the buoyancy, the stop step 41 can block the communication port 300, so as to improve the problem that the liquid is easy to spray from the exhaust port 301 of the exhaust pipe 30 during the liquid inlet process of the gas-liquid separator, thereby making the liquid flow out through the liquid outlet outlet 220 of the liquid outlet pipe 20, and improving the gas-liquid separation effect and safety of the gas-liquid separator.

[0082] In some embodiments, the stop step 41 is arranged in a circular arc, and the outer wall surface of the second exhaust pipe section 312 is an arc surface. The circular arc-shaped protrusion is relatively smooth and is not easy to damage the exhaust pipe 30 and the floating member 40.

[0083] Specifically, the stop step 41 protrudes towards the communication port 300 to block the communication port 300.

[0084] In some embodiments, the communication port 300 on the second exhaust pipe section 312 is provided with a plurality of communication ports 300, and the plurality of communication ports 300 are arranged along the circumference of the second exhaust pipe section 312 to ensure the exhaust area of the communication ports.

[0085] Referring to Figure 6 In some embodiments, the exhaust pipe 30 comprises a first exhaust pipe section 311 and a second exhaust pipe section 312, the first exhaust pipe section 311 is connected with the second exhaust pipe section 312, the pipe diameter of the first exhaust pipe section 311 is larger than that of the second exhaust pipe section 312, and the communication port 300 is arranged on the end face of the first exhaust pipe section 311 close to one end of the second exhaust pipe section 312, so that when the floating member 40 moves to the communication port 300 due to the buoyancy, the end portion of the floating member 40 blocks the communication port 300, thereby improving the problem that the liquid is easily sprayed out of the exhaust port 301 of the exhaust pipe 30 during the liquid inlet process of the gas-liquid separator, so that the liquid flows out through the liquid outlet 220 of the liquid outlet pipe 20, and the gas-liquid separation effect and the safety of the gas-liquid separator in use are improved.

[0086] In some embodiments, the communication port 300 on the first exhaust pipe section 311 is provided with a plurality of communication ports 300, and the plurality of communication ports 300 are arranged along the circumference of the first exhaust pipe section 311, so that compared with one communication port 300, the exhaust area of the exhaust pipe 30 is improved.

[0087] In some embodiments, the communication port 300 on the first exhaust pipe section 311 is provided with two communication ports 300, and the two communication ports 300 are both curved in shape, the length of each communication port 300 extends along the circumference of the first exhaust pipe section 311, and the two communication ports 300 are arranged at intervals. Compared with one communication port 300, the exhaust area of the exhaust pipe 30 is improved by the above-mentioned two communication ports 300.

[0088] In some embodiments, the floating member 40 is movably sleeved on the exhaust pipe 30, and a sealing ring is arranged between the outer wall surface of the exhaust pipe section 31 and the inner wall surface of the sleeve portion 121 to achieve the sealed connection between the outer wall surface of the exhaust pipe section 31 and the inner wall surface of the sleeve portion 121, thereby reducing the overflow of the liquid / scum from the outer wall surface of the exhaust pipe section 31 and the inner wall surface of the sleeve portion 121.

[0089] In some embodiments, the floating member 40 is movably sleeved on the exhaust pipe 30, and the exhaust port 301 of the exhaust pipe 30 is located in the overflow groove 112, so that the liquid / scum flowing out of the exhaust pipe 30 flows back into the containing space 100 of the containing member 10 from the exhaust port 301.
