A bubble elimination device for gas-liquid separation

Abstract

This invention discloses a bubble elimination device for gas-liquid separation, belonging to the field of defoaming devices. It includes: a bottom cover, a connecting cover mounted on the bottom cover, a top cover mounted on the top of the connecting cover, and a fixed connection between the top cover and the bottom cover via a mounting post. A liquid inlet pipe is connected through the center of the bottom cover. In this bubble elimination device for gas-liquid separation, liquid is conveyed upwards through the liquid inlet pipe and enters a flared opening. The diameter of the flared opening is larger than the diameter of the liquid inlet pipe. As the diameter of the liquid inlet pipe gradually increases, larger bubbles inside the liquid converge, thus eliminating them. After the larger bubbles are eliminated, they fall along the top of the flared opening into the interior of the separation cylinder. At this time, the rotating shaft drives the impeller to rotate, and the impeller drives the liquid in the separation cylinder to undergo high-speed centrifugal rotation. This centrifugal rotation separates the fine bubbles inside the liquid, facilitating efficient elimination of bubbles within the liquid.

Description

Technical Field

[0001] This invention relates to the field of defoaming device technology, specifically to a bubble elimination device for gas-liquid separation. Background Technology

[0002] In many industries involving fluid transport and handling, such as chemical, pharmaceutical, and food and beverage, air bubbles in fluids often have an adverse impact on the production process. For example, in pharmaceutical chromatography systems, air bubbles entering the chromatography column can lead to a decrease in column performance, thereby affecting the chromatography results. In chemical reactions, the presence of air bubbles can interfere with the reaction, reduce reaction efficiency, and even cause safety issues. Therefore, defoaming devices are needed to eliminate air bubbles in liquids during transport.

[0003] Authorization announcement number CN110090472B discloses a residue-free bubble trap, including an upper connecting pipe, a hollow body, a drain pipe, an inlet pipe, and an inlet tube. The hollow body includes an upper connector, a main body, and a lower connector. The upper connector and the lower connector are fixed to opposite sides of the main body. The upper connector has an upper connecting hole that communicates with the upper connecting pipe. The lower connector has a lower connecting hole and includes an inclined surface and a protrusion. The inclined surface extends downward and connects with the lower connecting hole. The protrusion has a through hole that penetrates the protrusion. The drain pipe communicates with the lower connecting hole. The through hole communicates with the inlet pipe and the inlet tube, respectively. The inlet tube protrudes from the lower connector. Liquid enters the hollow body through the drain pipe, and air bubbles are discharged through the upper connecting pipe. The inclined surface ensures that the liquid is fully discharged without any residue, thus improving the efficiency of liquid drainage. In this invention, liquid enters the hollow body through the drain pipe, and air bubbles are discharged through the upper connecting pipe. However, this method generally discharges larger air bubbles, while smaller air bubbles remain in the liquid. Furthermore, when the liquid falls onto the lower connector, it splashes onto the inner wall of the hollow body. The splashed liquid solidifies on the inner wall of the hollow body, which can contaminate the liquid, especially in pharmaceutical or food products. Summary of the Invention

[0004] The purpose of this invention is to provide a bubble elimination device for gas-liquid separation. The device can discharge larger bubbles in the liquid through the flared opening, and can also drive the liquid in the separation cylinder to centrifuge at high speed when the impeller rotates at high speed. When the liquid rotates at high speed, it can separate the fine bubbles inside, so that the bubbles inside the liquid can be eliminated efficiently.

A separating cylinder is rotatably mounted on the outer surface of the rotating shaft near the impeller. The rotation of the rotating shaft can drive the impeller to rotate, and the rotation of the impeller can cause the liquid to centrifugally rotate in the separating cylinder, discharging fine air bubbles.

[0007] The cleaning assembly includes a cleaning pipe, a cleaning frame, a three-way solenoid valve, and nozzles. The cleaning pipe is connected through the top of the top cover near the exhaust pipe. At least two nozzles are installed on the surface of the cleaning pipe. The cleaning pipe can deliver cleaning fluid to the inside of the nozzles and spray the cleaning fluid onto the inner wall of the connecting cover to clean residual liquid. A cleaning frame is provided on the side of the rotating shaft. A three-way solenoid valve is installed on the liquid outlet pipe. When the rotating shaft rotates, it can drive the cleaning frame to rotate. The rotation of the cleaning frame can clean the inner wall of the connecting cover.

[0008] Preferably, the defoaming assembly further includes a ring rack, a gear, and a drive motor. The ring rack is fixedly installed at the end of the rotating shaft, and a matching gear is connected to the side of the ring rack. The output end of the drive motor is installed at the center of the gear, and the bottom of the drive motor is fixedly installed at the bottom of the bottom cover.

[0009] Preferably, the defoaming assembly further includes a drain trough, drain pipes, support rods, and a controller. The drain trough is fixedly installed at the top of the separating cylinder. At least four drain pipes are fixedly installed in a ring array at the bottom of the drain trough. At least four support rods are fixedly installed in a ring array at the top of the drain trough. The other end of the support rods is installed at the bottom of the top cover. The controller is installed on the side of the bottom cover. The controller is connected to the drive motor by an electric wire.

[0010] Preferably, the cleaning assembly further includes a fixing plate and a telescopic rod. The fixing plate is installed at the top of the cleaning pipe, and the telescopic rod is fixedly installed at the top of the top cover. The output end of the telescopic rod is fixedly connected to the surface of the fixing plate. The telescopic rod is connected to the controller wire. The telescopic rod can drive the cleaning pipe to move vertically through the fixing plate.

[0011] Preferably, the cleaning assembly further includes a movable ring, a fixed ring, and an annular frame. The movable ring is sleeved on the outer surface of the rotating shaft, and the fixed ring is fixedly installed on the outer surface of the rotating shaft near the movable ring. The annular frame is fixedly installed on the outer surface of the movable ring. The upper surface of the annular frame is movably connected to the bottom end of the cleaning pipe, and the outer surface of the annular frame is fixedly connected to one end of the cleaning frame.

[0012] Preferably, the cleaning assembly further includes a squeezing groove, a spring, a rod, and slots. The bottom end of the movable ring has at least four squeezing grooves arranged in a circular array. A rod is movably installed inside the squeezing groove. The top end of the rod is connected to the top end of the squeezing groove by a spring. The top end of the fixed ring has at least four slots arranged in a circular array that match the rod.

[0013] Preferably, the cleaning assembly further includes a strip groove and strip cleaning holes. The cleaning frame has a strip groove on the side near the connecting cover, and at least three strip cleaning holes are equally spaced on the side of the strip groove near the connecting cover. When the cleaning frame rotates, it can scrape the cleaning fluid into the interior of the strip groove for guidance. The cleaning fluid inside the strip groove can then clean the inner wall of the connecting cover that has not been in contact with the cleaning fluid through the strip cleaning holes.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the bubble elimination device for gas-liquid separation;

[0015] 1. Liquid is conveyed upward through the inlet pipe and enters the flared port. The diameter of the flared port is larger than that of the inlet pipe. As the diameter of the inlet pipe increases, larger air bubbles inside the liquid gather, thus eliminating them. After the larger air bubbles are eliminated, they fall into the separation cylinder along the top of the flared port. At this time, the rotating shaft drives the impeller to rotate. The rotation of the impeller drives the liquid in the separation cylinder to centrifuge at high speed. The centrifugal rotation of the liquid can separate the fine air bubbles inside, making it convenient for the air bubbles inside the liquid to be eliminated efficiently.

[0016] 2. The cleaning fluid can be delivered to the inner wall of the nozzle through the cleaning pipe, and the nozzle can spray the cleaning fluid onto the inner wall of the connecting cover for cleaning. When the shaft rotates, the cleaning frame can be driven to rotate through the cooperation of the parts. When the cleaning frame rotates, it can clean the inner wall of the connecting cover. When the inner wall of the connecting cover is cleaned, the three-way solenoid valve can be activated by operating the controller. When the three-way solenoid valve is activated, the waste liquid flowing into the outlet pipe can be discharged. The three-way solenoid valve can discharge liquid and waste liquid separately. The liquid can be discharged through the outlet pipe and the waste liquid pipe, which facilitates regular cleaning of the inside of the connecting cover.

[0017] 3. Equipped with a controller to control the speed of the drive motor, thereby controlling the speed of the impeller, which facilitates adjustment of the impeller speed according to different liquid concentrations;

[0018] 4. When the telescopic rod is in operation, it can drive the cleaning pipe to move vertically through the fixed plate. At the same time, the cleaning pipe can drive the ring frame and the movable ring to move vertically. When the movable ring moves, it can be separated from the fixed ring through the cooperation of the parts. After the movable ring is separated from the fixed ring, the rotating shaft rotates and only drives the impeller to rotate. This avoids the liquid from colliding with the liquid when the ring frame rotates during the drainage pipe, so that the liquid can fall gently to the bottom cover. Attached Figure Description

[0038] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0039] Please see Figures 1-4 , Figure 7 The present invention provides an embodiment of a bubble elimination device for gas-liquid separation, comprising: a bottom cover 100, a connecting cover 400 mounted on the bottom cover 100, a top cover 300 mounted on the top of the connecting cover 400, the top cover 300 and the bottom cover 100 being fixedly connected by a mounting post 200, an inlet pipe 500 being connected through the center of the bottom cover 100, an outlet pipe 600 being mounted on the bottom of the bottom cover 100 near the bottom of the inlet pipe 500, an exhaust pipe 700 being mounted on the center of the top cover 300, a defoaming component 800 being mounted on the inlet pipe 500, and a cleaning component 900 being mounted on the defoaming component 800.

[0040] It should be noted that during use, the connecting cover 400 can be installed in the annular groove between the bottom cover 100 and the top cover 300, and the bottom cover 100 and the top cover 300 can be fixed by the mounting post 200. After the device is installed, it can be used. Liquid can enter the interior of the connecting cover 400 through the liquid inlet pipe 500. When the liquid enters, the larger air bubbles inside will float upward to the top of the liquid inlet pipe 500. After the air bubbles float to the top of the liquid inlet pipe 500, they will burst. After the air bubbles burst, they can be discharged through the exhaust pipe 700. After the liquid is delivered to the top of the liquid inlet pipe 500, it will fall into the defoaming component 800. The defoaming component 800 can eliminate the small air bubbles inside the liquid, thereby improving the air bubble elimination effect. After the air bubbles inside the liquid are eliminated, they will fall onto the bottom cover 100 and be discharged through the liquid outlet pipe 600 on the bottom cover 100. When the device needs to be cleaned, the liquid splashed onto the inner wall of the connecting cover 400 can be cleaned by the cleaning component 900.

[0041] like Figures 1-4 , Figure 7As shown, the defoaming component 800 includes a rotating shaft 810, a flared end 820, an impeller 830, and a separating cylinder 840. The top of the liquid inlet pipe 500 is provided with a flared end 820, which can transport liquid into the flared end 820 and discharge larger air bubbles inside the liquid through the flared end 820. The rotating shaft 810 is rotatably mounted on the outer surface of the liquid inlet pipe 500. The bottom end of the rotating shaft 810 penetrates the top of the bottom cover 100, and the rotating shaft 810 is rotatably connected to the bottom cover 100. The top end of the rotating shaft 810 is mounted with an impeller 830. The separating cylinder 840 is rotatably mounted on the outer surface of the rotating shaft 810 near the impeller 830. The rotation of the rotating shaft 810 can drive the impeller 830 to rotate, and the rotation of the impeller 830 can drive the liquid to centrifugally rotate inside the separating cylinder 840 to discharge small air bubbles.

[0042] It is conceivable that the liquid, when transported upward through the inlet pipe 500, will enter the flared port 820. The diameter of the flared port 820 is larger than that of the inlet pipe 500. As the diameter of the inlet pipe 500 increases, larger air bubbles inside the liquid will gather, thereby eliminating the larger air bubbles inside the liquid. After the larger air bubbles inside the liquid are eliminated, they will fall into the interior of the separation cylinder 840 along the top of the flared port 820. At this time, when the rotating shaft 810 rotates, it can drive the impeller 830 to rotate. When the impeller 830 rotates, it can drive the liquid in the separation cylinder 840 to rotate at high speed. When the liquid rotates at high speed, it can separate the small air bubbles inside.

[0043] like Figures 1-4 , Figure 7 As shown, the defoaming component 800 also includes an annular rack 850, a gear 860, and a drive motor 870. The annular rack 850 is fixedly installed at the end of the rotating shaft 810. The gear 860 is connected to the side of the annular rack 850. The output end of the drive motor 870 is installed at the center of the gear 860. The bottom of the drive motor 870 is fixedly installed at the bottom of the bottom cover 100.

[0044] It is worth noting that the drive motor 870 can drive the gear 860 to rotate. When the gear 860 rotates, it can drive the ring rack 850 to rotate. When the ring rack 850 rotates, it will drive the rotating shaft 810 to rotate. When the rotating shaft 810 rotates, it can rotate with the bottom cover 100 through the bearing. At the same time, the rotating shaft 810 can rotate between the liquid inlet pipe 500 and the separation cylinder 840 through the bearing.

[0045] like Figures 1-4 , Figure 7As shown, the defoaming component 800 also includes a drain trough 880, a drain pipe 890, a support rod 8100, and a controller 8110. The drain trough 880 is fixedly installed at the top of the separating cylinder 840. At least four drain pipes 890 are fixedly installed in a ring array at the bottom of the drain trough 880. At least four support rods 8100 are fixedly installed in a ring array at the top of the drain trough 880. The other end of the support rod 8100 is installed at the bottom of the top cover 300. The controller 8110 is installed on the side of the bottom cover 100. The controller 8110 is connected to the drive motor 870 by wires.

[0046] It is understood that after the liquid bubbles are separated, they can enter the drain tank 880 and be transported to the bottom cover 100 through the drain pipe 890 in the drain tank 880. The drain pipe 890 is provided with four pipes to discharge the liquid in a timely manner, thereby preventing the liquid from flowing back into the separator 840. Furthermore, the end of the drain pipe 890 faces the bottom cover 100, thereby reducing the splash range when the liquid is discharged.

[0047] The controller 8110 can control the drive motor 870, the telescopic rod 940 and the three-way solenoid valve 9140 respectively according to the usage requirements. The controller 8110 can also control the speed of the drive motor 870, so that the drive motor 870 can adjust the speed according to the concentration of different liquids.

[0048] like Figures 1-3 , Figure 5 and Figure 6 As shown, the cleaning assembly 900 includes a cleaning pipe 910, a cleaning frame 920, a three-way solenoid valve 9140, and a nozzle 950. The cleaning pipe 910 is connected through the top of the top cover 300 near the exhaust pipe 700. At least two nozzles 950 are installed on the surface of the cleaning pipe 910. The cleaning pipe 910 can deliver cleaning fluid to the inside of the nozzles 950, and the cleaning fluid is sprayed onto the inner wall of the connecting cover 400 through the nozzles 950 to clean residual liquid. The cleaning frame 920 is provided on the side of the rotating shaft 810, and the three-way solenoid valve 9140 is installed on the liquid outlet pipe 600. When the rotating shaft 810 rotates, it can drive the cleaning frame 920 to rotate. The rotation of the cleaning frame 920 can clean the inner wall of the connecting cover 400.

[0049] It should be understood that the cleaning fluid can be delivered to the inner wall of the nozzle 950 through the cleaning pipe 910, and the nozzle 950 can spray the cleaning fluid onto the inner wall of the connecting cover 400 for cleaning. When the rotating shaft 810 rotates, it can drive the cleaning frame 920 to rotate through the cooperation of the parts. When the cleaning frame 920 rotates, it can clean the inner wall of the connecting cover 400. When the inner wall of the connecting cover 400 is being cleaned, the three-way solenoid valve 9140 can be activated by operating the controller 8110. When the three-way solenoid valve 9140 is activated, the waste liquid flowing into the outlet pipe 600 can be discharged. The three-way solenoid valve 9140 can discharge the liquid and waste liquid separately. The liquid can be discharged through the outlet pipe 600 and the waste liquid pipe.

[0050] like Figures 1-3 , Figure 5 and Figure 8 As shown, the cleaning assembly 900 also includes a fixing plate 930 and a telescopic rod 940. The fixing plate 930 is installed at the top of the cleaning pipe 910, and the telescopic rod 940 is fixedly installed at the top of the top cover 300. The output end of the telescopic rod 940 is fixedly connected to the surface of the fixing plate 930. The telescopic rod 940 is wired to the controller 8110. When the telescopic rod 940 is working, it can drive the cleaning pipe 910 to move vertically through the fixing plate 930.

[0051] It should be noted that when the inner wall of the connecting cover 400 needs to be cleaned, the telescopic rod 940 is activated by operating the controller 8110. When the telescopic rod 940 is activated, it can pull the fixed plate 930 downward. When the fixed plate 930 moves downward, it can drive the cleaning pipe 910 to move vertically. When the cleaning pipe 910 moves vertically, it can drive the nozzle 950 to move to the designated position. At the same time as the cleaning pipe 910 moves, it can drive the ring frame 970 and the movable ring 980 to move vertically.

[0052] like Figures 1-3 , Figure 5 , Figure 6 and Figure 8 As shown, the cleaning assembly 900 also includes a movable ring 980, a fixed ring 990, and an annular frame 970. The movable ring 980 is sleeved on the outer surface of the rotating shaft 810. The fixed ring 990 is fixedly installed on the outer surface of the rotating shaft 810 near the movable ring 980. The annular frame 970 is fixedly installed on the outer surface of the movable ring 980. The upper surface of the annular frame 970 is movably connected to the bottom end of the cleaning tube 910. The outer surface of the annular frame 970 is fixedly connected to one end of the cleaning frame 920.

[0053] It is conceivable that when the ring frame 970 moves vertically, it can drive the movable ring 980 and the cleaning frame 920 to move vertically respectively. When the movable ring 980 moves vertically, it can be connected to the fixed ring 990 through components. When the movable ring 980 and the fixed ring 990 are connected, the rotating shaft 810 can rotate and drive the fixed ring 990 to rotate. When the fixed ring 990 rotates, it can drive the movable ring 980 to rotate through components. When the movable ring 980 rotates, it can drive the ring frame 970 to rotate. When the ring frame 970 rotates, its upper surface can rotate with the bottom end of the cleaning pipe 910. At the same time, the rotation of the ring frame 970 can drive the cleaning frame 920 to rotate. When the cleaning frame 920 rotates, it can clean the inner wall of the connecting cover 400.

[0054] like Figures 1-3 , Figure 5 and Figure 8 As shown, the cleaning assembly 900 also includes a squeezing groove 9100, a spring 9110, a rod 9120, and a slot 9130. The bottom end of the movable ring 980 is provided with at least four squeezing grooves 9100 in a circular array. The rod 9120 is movably installed inside the squeezing groove 9100. The top end of the rod 9120 is connected to the top end of the squeezing groove 9100 by the spring 9110. The top end of the fixed ring 990 is provided with at least four slots 9130 that match the rod 9120 in a circular array.

[0055] It is worth noting that when the movable ring 980 moves downward, it can drive the insertion rod 9120 to move. When the insertion rod 9120 is not aligned with the slot 9130, the bottom end of the insertion rod 9120 will contact the fixed ring 990. As the movable ring 980 continues to move downward, the fixed ring 990 will push the insertion rod 9120 to slide upward on the pressing groove 9100. At the same time, the insertion rod 9120 will move the spring 9110. When the movable ring 980 moves to the designated position, the rotating shaft 810 can rotate, which can drive the fixed ring 990 and the slot 9130 to rotate. When the slot 9130 rotates to the bottom end of the insertion rod 9120, the insertion rod 9120 can be inserted into the interior of the slot 9130 through the spring 9110. At this time, the rotation of the fixed ring 990 can drive the movable ring 980 to rotate through the insertion rod 9120.

[0056] like Figures 1-3 , Figure 5 , Figure 6 and Figure 8As shown, the cleaning assembly 900 also includes a strip groove 960 and strip cleaning holes 9150. The cleaning frame 920 has a strip groove 960 on the side near the connecting cover 400. At least three strip cleaning holes 9150 are equally spaced on the side of the strip groove 960 near the connecting cover 400. When the cleaning frame 920 rotates, it can scrape the cleaning fluid into the interior of the strip groove 960 for guidance. The cleaning fluid inside the strip groove 960 can then clean the inner wall of the connecting cover 400 that has not been in contact with the cleaning fluid through the strip cleaning holes 9150.

[0057] It is clear that when the ring frame 970 rotates, it can drive the cleaning frame 920 to rotate. When the cleaning frame 920 rotates, it can clean the inner wall of the connecting cover 400. When the cleaning frame 920 rotates to the point where the nozzle 950 sprays, the cleaning frame 920 can guide part of the sprayed cleaning liquid through the strip groove 960. After the cleaning liquid enters the strip groove 960, it can be transported again through the strip cleaning hole 9150 to the side of the cleaning frame 920 that contacts the connecting cover 400, so that the inner wall of the connecting cover 400 can also be cleaned except for the spraying area.

[0058] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
