Description

Technical Field

[0001] The present application relates to the technical field of bubble point analysis devices, and in particular to a self-cleaning bubble point analysis device. Background Art

[0002] In the current field of filter element bubble point analysis technology, a bubble point analysis device consisting of a liquid tank, air pump, conical sieve, and drain valve is widely used. This device injects a test liquid (primarily an organic solvent such as ethanol or isopropanol) into the liquid tank and uses an air pump to seal and pressurize the filter element through the conical sieve to test the filter element's bubble point performance. This analysis method plays an important role in filter element quality testing.

[0003] However, in actual operation, due to the highly corrosive nature of test fluids (such as ethanol and isopropyl alcohol), after the test is completed, although most of the test fluid can be drained through the drain valve, a small amount of test fluid often remains on the inner wall of the tank. If this residue is not removed promptly, it will act on the tank material over time, causing gradual corrosion inside the tank, thereby affecting its structural integrity and ultimately shortening the tank's service life. This corrosion not only increases the frequency of tank replacement but also increases the overall maintenance cost of the equipment.

[0004] Therefore, the present application provides a self-cleaning bubble point analysis device to solve the above problems. Utility Model Content

[0005] The present application provides a self-cleaning bubble point analyzer, which aims to solve the problems raised in the background art, such as the inability of the existing self-cleaning bubble point analyzer to clean the residual liquid inside the liquid tank, which easily causes corrosion of the liquid tank and affects the service life of the liquid tank.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a self-cleaning bubble point analyzer, comprising a bubble point analyzer body, a conical sieve connected to the bubble point analyzer body via an air pipe, a base disposed on the bubble point analyzer body, a detection cylinder disposed on the top of the base, and a drain valve disposed on the detection cylinder;

[0007] To facilitate cleaning of the interior of the test tube and prevent residual testing liquid, the test tube is equipped with a cleaning mechanism. This mechanism comprises a water tank mounted on the bubble point analyzer, a water pump mounted on the water tank and connected to the interior of the water tank, a ring tube mounted on the top of the test tube and connected to the output of the water pump, and a nozzle plugged into the top of the test tube and connected to the ring tube. When the cleaning mechanism is activated, the water pump draws cleaning fluid from the water tank, delivers it through the ring tube to the nozzle, and then rinses the interior of the test tube with a high-pressure spray. During the rinsing process, the cleaning fluid mixes with any residual material on the inner wall of the test tube and is discharged through the drain valve until the interior of the test tube is completely clean. Finally, the water pump and drain valve are closed, completing the cleaning process. This device has a simple and clear operating principle and is easy to operate, making it convenient for cleaning the interior of the test tube.

[0008] To improve the cleaning effectiveness of the nozzles and prevent liquid from splashing onto the exterior of the test tube during cleaning, three nozzles are preferably provided, oriented diagonally downward. These three downward-facing nozzles can operate simultaneously, providing a comprehensive, multi-angle flushing of the inner wall of the test tube, significantly improving cleaning efficiency and shortening cleaning time. The diagonal downward spray direction effectively suppresses splashing of the cleaning liquid, reduces pollution to the surrounding environment, and protects the safety of the operator.

[0009] Preferably, the water pump and the annular tube are connected via a water pipe. Tightly connecting the water pump and the annular tube via the water pipe ensures the stability and continuity of the cleaning liquid during delivery, avoiding poor cleaning results due to loose connections or leakage. The simple and clear connection of the water pipe facilitates routine maintenance and replacement, reducing maintenance costs and difficulty.

[0010] Preferably, to facilitate adaptability of the test cylinder to filter cartridges of varying lengths, the test cylinder consists of a fixed cylinder and a movable sleeve. The movable sleeve is mounted on top of the fixed cylinder, and a drive mechanism is provided on the base for adjusting the height of the movable sleeve. The drain valve is fixedly mounted on the bottom of the fixed cylinder. By adjusting the height of the movable sleeve, the test cylinder can easily adapt to filter cartridges of varying lengths without requiring replacement of the entire test cylinder, reducing operational costs and improving equipment utilization. Rapid adjustment of the test cylinder's height allows for rapid matching of filter cartridges of varying specifications, shortening test preparation time and improving test efficiency.

[0011] Preferably, to ensure the seal of the test cylinder after height adjustment and prevent leakage of the test fluid from the gap between the fixed cylinder and the movable sleeve during testing, the fixed cylinder is provided with a sealing ring for sealing the gap between the fixed cylinder and the movable sleeve. The introduction of the sealing ring significantly improves the sealing performance between the fixed cylinder and the movable sleeve, effectively preventing leakage of the test fluid during testing, and ensuring the accuracy and reliability of the test. Good sealing performance reduces user concerns about leakage during use, improving the overall user experience and satisfaction of the device.

[0012] Preferably, the drive mechanism includes a connecting ring fixedly mounted on the movable sleeve and a cylinder fixedly mounted on the top side of the base and fixedly connected to the connecting ring for driving the movable sleeve toward or away from the base. As a power source, the cylinder offers fast response and high control accuracy, enabling precise control of the movable sleeve's height position to meet the testing requirements of filter elements of varying specifications. The cylinder's attachment to the base increases overall structural stability, reduces deviations and errors caused by vibration or external forces, and improves the reliability and durability of the device.

[0013] Preferably, the drive mechanism further includes a fixed sleeve fixedly connected to the top of the base, and a guide rod inserted into the fixed sleeve and fixedly connected to the bottom end of the connecting ring. The combination of the guide rod and the fixed sleeve provides a stable guide path for the movement of the movable sleeve, reducing errors caused by offset or shaking, and improving detection accuracy. The linear motion characteristics of the guide rod enable the movable sleeve to maintain a high degree of parallelism and perpendicularity during movement, further improving the accuracy of height adjustment.

[0014] Through the design of a cleaning mechanism, this application achieves efficient and convenient cleaning of the interior of the test tube. This design simplifies operation, improves work efficiency, and reduces environmental pollution and safety hazards caused by improper handling of residual test fluid. The cleaning mechanism utilizes a water tank to store cleaning fluid, which is then pressurized and pumped to a ring pipe by a water pump. Finally, a nozzle evenly sprays the cleaning fluid onto the inner wall of the test tube. This design effectively addresses the corrosion problem caused by residual liquid inside the test tube of traditional bubble point analyzers after testing, extending the device's service life and reducing maintenance costs.

[0015] By adjusting the height of the movable sleeve, the test tube can easily adapt to filter elements of different lengths without having to replace the entire test tube, reducing usage costs and improving equipment utilization. Quickly adjusting the height of the test tube allows for quick matching of filter elements of different specifications, shortening test preparation time and improving test efficiency.

[0022] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] Example 1

[0024] This embodiment provides a self-cleaning bubble point analysis device, such as Figure 1-4 As shown, the bubble point analyzer comprises a bubble point analyzer body 1, a conical sieve 2 connected to the bubble point analyzer body 1 via an air pipe, a base 3 mounted on the bubble point analyzer body 1, a detection cylinder 4 mounted on top of the base 3, and a drain valve 5 mounted on the detection cylinder 4. The detection cylinder 4 is made of transparent glass, making it easy to observe the cleaning effect and ensure thorough cleaning. It also facilitates observation of the bubble point on the filter element surface. When performing a bubble point test on a filter element, the test liquid (ethanol or isopropanol) is poured into the detection cylinder 4, and the conical sieve 2 is then inserted into the port of the filter element to be tested to achieve a seal. Next, the filter element is completely immersed in the liquid in the detection cylinder 4, and the bubble point analyzer body 1 is activated. A gradually increasing air pressure is applied to the interior of the filter element through the air pipe until bubbles appear in the filter element. The air pressure at this point is the bubble point value of the filter element. After the bubble point test is completed, the drain valve 5 is opened to drain the test liquid from the detection cylinder 4.

[0025] To facilitate cleaning of the interior of the test tube 4 and prevent residual test liquid, the test tube 4 is provided with a cleaning mechanism 6 for cleaning the interior of the test tube 4. This cleaning mechanism 6 comprises a water tank 61 mounted on the bubble point analyzer body 1, a water pump 62 mounted on and connected to the interior of the water tank 61, a ring tube 63 mounted on the top of the test tube 4 and connected to the output of the water pump 62, and a spray head 64 plugged into the top of the test tube 4 and connected to the ring tube 63. The addition of the cleaning mechanism 6 enables efficient and convenient cleaning of the interior of the test tube 4, facilitating simple operation and improving work efficiency. It also reduces environmental pollution and safety hazards caused by improper handling of residual test liquid. The cleaning mechanism 6 utilizes the water tank 61 to store cleaning liquid, which is then pressurized and delivered to the ring tube 63 by the water pump 62. Finally, the spray head 64 evenly sprays the cleaning liquid onto the inner wall of the test tube 4. This design effectively solves the corrosion problem caused by residual liquid inside the test tube 4 after testing in conventional bubble point analyzers, extending the service life of the equipment and reducing maintenance costs. When cleaning mechanism 6 is activated, water pump 62 draws cleaning fluid from water tank 61 and delivers it to nozzle 64 via annular pipe 63, where it is used to thoroughly rinse the inner wall of detection tube 4 in the form of a high-pressure spray. During the rinsing process, the cleaning fluid mixes with any residue on the inner wall of detection tube 4 and is discharged through drain valve 5 until the interior of detection tube 4 is completely clean. Finally, water pump 62 and drain valve 5 are closed, completing the cleaning process. This device features a simple and straightforward operating principle and is easy to operate, making it convenient for cleaning the interior of detection tube 4.

[0026] Specifically, to improve the cleaning effect of the nozzles 64 and prevent liquid from splashing onto the exterior of the detection tube 4 during the cleaning process, three nozzles 64 are provided, arranged diagonally downward. All three nozzles 64 are installed diagonally downward at the top of the detection tube 4. This layout ensures that the cleaning liquid more fully covers the inner wall of the detection tube 4 during spraying, reducing blind spots. Furthermore, the diagonal downward spray angle effectively reduces the possibility of cleaning liquid splashing onto the exterior of the detection tube 4, maintaining a clean working environment. The three diagonal downward nozzles 64 can operate simultaneously, providing a comprehensive, multi-angle flushing of the inner wall of the detection tube 4, significantly improving cleaning efficiency and shortening cleaning time. The diagonal downward spray direction effectively suppresses splashing of cleaning liquid, reduces pollution to the surrounding environment, and protects the safety of the operator. After the bubble point test is completed, the water pump 62 of the cleaning mechanism 6 is activated, and the cleaning liquid in the water tank 61 is pumped out and transported via a pipe to the annular pipe 63. The annular pipe 63 evenly distributes the cleaning liquid to the three diagonal downward nozzles 64. Under pressure, the cleaning liquid sprays from nozzle 64 in the form of a mist, directly impacting the inner wall of detection tube 4. Because nozzle 64 is angled downward, the cleaning liquid flows along the inner wall, thoroughly covering and flushing away any residue. The wastewater and residue generated during the flushing process are ultimately discharged from detection tube 4 through drain valve 5, completing the cleaning process. The entire operating principle is simple, efficient, and easily automated.

[0027] Specifically, water pump 62 and annular pipe 63 are connected via a water pipe. Tightly connecting water pump 62 and annular pipe 63 via the water pipe ensures the stability and continuity of the cleaning liquid during delivery, avoiding poor cleaning results caused by loose connections or leaks. The simple and clear water pipe connection facilitates routine maintenance and replacement, reducing maintenance costs and difficulty.

[0028] To facilitate adaptability to filter cartridges of varying lengths, the test cartridge 4 consists of a fixed cartridge 41 and a movable sleeve 42. The movable sleeve 42 is mounted on top of the fixed cartridge 41. A drive mechanism 7 is provided on the base 3 for adjusting the height of the movable sleeve 42. A drain valve 5 is fixedly mounted on the bottom of the fixed cartridge 41. The fixed cartridge 41, serving as the main body of the test cartridge 4, is stably mounted on the base 3, while the movable sleeve 42 is mounted on top of the fixed cartridge 41 and its height is adjusted by the drive mechanism 7. This modular design allows the test cartridge 4 to be flexibly adjusted based on the length of the filter cartridge being tested, thereby meeting the bubble point testing requirements of filter cartridges of varying specifications. By adjusting the height of the movable sleeve 42, the test cartridge 4 can easily adapt to filter cartridges of varying lengths without having to replace the entire test cartridge 4, reducing operational costs and improving equipment utilization. Quickly adjusting the height of the test cartridge 4 allows for rapid adaptation to filter cartridges of varying specifications, shortening test preparation time and improving test efficiency. When testing filter elements of different lengths, the movable sleeve 42 is first adjusted in height using the drive mechanism 7. Under the action of the drive mechanism 7, the movable sleeve 42 smoothly rises or descends along the outer wall of the fixed cylinder 41 until it reaches a height that matches the filter element to be tested. At this point, the test fluid is added to the interior of the test cylinder 4 until the filter element is completely immersed. The filter element is then inserted into the conical sieve 2 and sealed, and the entire filter element is immersed in the test fluid within the test cylinder 4. Subsequently, the bubble point analyzer body 1 is activated to perform a bubble point test. After the test is complete, the test fluid is drained through the drain valve 5, and the test cylinder 4 is cleaned using the cleaning mechanism 6.

[0029] Furthermore, to ensure the seal of the test tube 4 after the height adjustment and to prevent the test fluid from leaking from the gap between the fixed tube 41 and the movable sleeve 42 during the test process, a sealing ring 411 is provided on the fixed tube 41 to seal the gap between the fixed tube 41 and the movable sleeve 42. Made of a highly elastic, corrosion-resistant material such as silicone or fluororubber, the sealing ring 411 fits tightly against the surfaces of the fixed tube 41 and the movable sleeve 42, forming an effective sealing barrier. The introduction of the sealing ring 411 significantly improves the sealing performance between the fixed tube 41 and the movable sleeve 42, effectively preventing leakage of the test fluid during the test process and ensuring the accuracy and reliability of the test. This excellent sealing performance reduces user concerns about leakage during use, improving the overall user experience and satisfaction of the device. When the movable sleeve 42 moves up and down along the fixed tube 41 to the desired position under the action of the drive mechanism 7, the sealing ring 411 fits tightly against the contact surface between the fixed tube 41 and the movable sleeve 42. Because the material used for sealing ring 411 has excellent elasticity and resilience, it automatically adjusts to the shape and size of the contact surface, ensuring a tight and uniform seal. During testing, even under the influence of internal pressure or external vibration, sealing ring 411 maintains a stable seal, preventing leakage of the test fluid from the gap. To further enhance the sealing effect, apply an appropriate amount of lubricant or sealant when installing sealing ring 411 to reduce friction and improve sealing performance.

[0030] Specifically, the drive mechanism 7 comprises a connecting ring 71 fixedly mounted on the movable sleeve 42 and a cylinder 72 fixedly mounted on the top side of the base 3 and fixedly connected to the connecting ring 71, which drives the movable sleeve 42 toward or away from the base 3. As a power source, the cylinder 72 features fast response speed and high control accuracy, enabling precise control of the height position of the movable sleeve 42 to meet the testing requirements of filter cartridges of different specifications. The cylinder 72's attachment to the base 3 enhances the stability of the overall structure, reduces deviation and error caused by vibration or external forces, and improves the reliability and durability of the device. When the height of the detection cylinder 4 needs to be adjusted to accommodate filter cartridges of different lengths, the control system sends a command to the cylinder 72. Upon receiving the command, the cylinder 72 begins operating according to the preset stroke and speed. The movement of the piston within it generates a thrust or pull that acts on the connecting ring 71. Since the connecting ring 71 is fixedly connected to the movable sleeve 42, the thrust or pull of the cylinder 72 is converted into an upward or downward movement of the movable sleeve 42. As the movable sleeve 42 moves, the overall height of the test cylinder 4 changes until it reaches a height that matches the filter element to be tested. At this point, the cylinder 72 is stopped, and the filter element is inserted into the conical sieve 2 for subsequent bubble point testing. Throughout this process, the thrust, stroke, and speed of the cylinder 72 can be precisely adjusted via the control system to meet diverse testing requirements. Furthermore, the presence of the sealing ring 411 ensures a tight seal between the movable sleeve 42 and the fixed cylinder 41 during movement, preventing leakage of the test fluid.

[0031] More specifically, the drive mechanism 7 also includes a fixed sleeve 73 fixedly connected to the top of the base 3 and a guide rod 74 inserted into the fixed sleeve 73 and fixedly connected to the bottom end of the connecting ring 71. The cooperation between the guide rod 74 and the fixed sleeve 73 provides a stable guide path for the movement of the movable sleeve 42, reducing errors caused by deviation or shaking, and improving the accuracy of detection. The linear motion characteristics of the guide rod 74 enable the movable sleeve 42 to maintain a high degree of parallelism and perpendicularity during movement, further improving the accuracy of height adjustment. Before the cylinder 72 begins operation, the guide rod 74 is located within the fixed sleeve 73 and fixedly connected to the bottom end of the connecting ring 71. When the cylinder 72 receives a command from the control system, the piston inside it begins to move, generating a thrust or pull on the connecting ring 71. Because the connecting ring 71 is fixedly connected to the guide rod 74, the thrust or pull of the cylinder 72 is converted into sliding movement of the guide rod 74 within the fixed sleeve 73. Guide rod 74 moves linearly along the axis of fixed sleeve 73, simultaneously driving connecting ring 71 and movable sleeve 42 upward or downward. During this movement, guide rod 74 provides guidance, ensuring smooth and accurate movement of movable sleeve 42. When movable sleeve 42 reaches a predetermined height, cylinder 72 stops operating. At this point, the total height of test tube 4 matches the filter element to be tested, allowing subsequent bubble point testing to proceed.

[0032] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
