Description

Technical Field

[0001] The invention relates to the technical field of filter tube testing, in particular to a filter testing device for a water-emulsified liquid filter tube. Background Art

[0002] A water-emulsified liquid filter tube is a tubular filter device used to filter water-emulsified liquids. Water-emulsified liquids usually refer to a mixture of water and oil, which is formed through a specific emulsification process. During the production of water-emulsified liquid filter tubes, filtration testing equipment is required to test the oil-water permeability of the filter tubes, thereby evaluating the oil-water separation performance of the filter tubes.

[0003] At present, when using a filtration test device for a water-emulsified liquid filter tube, the filter tube needs to be placed above a fixed test tube, and then the sliding test tube is driven to move downward. The two ends of the filter tube are clamped by the fixed test tube and the sliding test tube, and the liquid outlet of the sliding test tube is connected to the liquid inlet of the filter tube, and the liquid inlet of the fixed test tube is connected to the liquid outlet of the filter tube. Then, the test liquid is input into the sliding test tube through the infusion tube, passed through the filter tube, and then the test liquid passing through the filter tube is collected and tested, thereby testing the permeability of the filter tube.

[0004] However, since the sliding test tube needs to slide up and down continuously to complete the clamping and connection of the filter tube, and the infusion tube connected to the sliding test tube is generally a hose, the connection between the infusion hose and the sliding test tube will be constantly subjected to pressure and tension during the frequent up and down movement of the sliding test tube, which makes the connection between them prone to wear, resulting in leakage of test liquid at the connection between the infusion hose and the sliding test tube during testing, and further making it impossible for the test liquid to maintain the flow at the predetermined pressure or speed, which not only affects the accuracy of the test results, but also causes waste of test liquid.

[0019] Compared with the prior art, the present invention provides a filtration test device for water emulsion liquid filter tube, which has the following features:

[0020] Beneficial effects:

[0021] 1. When the test fluid leaks, the warning sign and the alarm will send out warning signals simultaneously under the drive of the buoyancy float, so that the staff can promptly discover and make countermeasures when the leakage occurs at the connection between the infusion hose and the sliding test tube, thus avoiding the problem of the leakage affecting the accuracy of the test results. At the same time, the setting of the warning sign can also be deployed and send out warning signals when the alarm or electrical contacts have power outages or other faults, which improves the reminder effect for the staff and ensures the stability of the warning work.

[0022] 2. When the test box stores too much liquid, the buoyancy will open the drain port of the test box. The excess test liquid will be discharged from the drain port on the test box and diverted into the collection box through the liquid guide rail to collect the excess test liquid. This not only avoids the overflow of the test liquid from the diversion groove due to excessive test liquid, but also prevents the leaked test liquid from dripping onto the body or the surrounding area, causing the body or the surrounding environment to be slippery and affecting the test work. In addition, the collected test liquid can be reused by collecting it, saving resources and reducing the cost of test liquid.

[0023] 3. The lubricating liquid in the liquid reservoir is squeezed from the U-shaped tube into the fixed tube by the increased air pressure, and then discharged from the dripping port at the bottom of the fixed tube, accurately dripping onto the slideway of the drive seat, thereby reducing the friction of the drive seat when sliding. The air pressure in the liquid reservoir is increased by the compression of the airbag, thereby realizing automatic dripping of the lubricating liquid, saving labor costs. Compared with traditional pumps or mechanical conveying systems, liquid conveying through air pressure can avoid contact with the lubricating liquid, thereby reducing the risk of contamination of the lubricating liquid and ensuring the quality of the lubricating liquid when added;

[0024] 4. Through the arrangement of the pawl, ratchet, turntable and bump, the drive seat can squeeze the airbag once after detecting the corresponding number of filter tubes each time, thus avoiding the instability during manual addition and the waste of lubricant due to excessive addition. It makes the lubricant addition more regular, thus ensuring the stability of the lubricant dosage each time, guaranteeing the lubrication cycle, and reducing the frequency of manual lubrication and maintenance work.

[0025] 5. Through the setting of the one-way air inlet valve and the one-way air outlet valve, gas can enter the airbag from the outside, so as not to change the air pressure in the liquid reservoir. The air pressure in the liquid reservoir increases each time the airbag is compressed, thereby ensuring the stable addition of lubricating fluid. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0041] Embodiments of the present invention

[0042] Please refer to Figures 1 to 7 As shown:

[0043] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a filtering test device for a water-emulsified liquid filter tube, including a body 1, a driving seat 2 is slidably connected to one side of the body 1, the bottom of the driving seat 2 can be fixedly connected to the output end of an external driving cylinder, and the driving seat 2 can be driven to slide up and down by the external driving cylinder, and the driving seat 2 is fixedly connected to a sliding test tube 21 on the side away from the body 1, and a fixed test tube 22 is fixedly connected to one side of the body 1. The fixed test tube 22 is located below the sliding test tube 21, and an infusion hose 3 is fixedly connected to the outer surface of the sliding test tube 21. The end of the infusion hose 3 away from the sliding test tube 21 is installed on one side of the body 1. The filtering test device for the water-emulsified liquid filter tube also includes: a detection and collection mechanism and a regular maintenance mechanism, and the regular maintenance mechanism is located on the left side of the detection and collection mechanism;

[0044] The detection and collection mechanism is used to detect whether the test liquid is leaking;

[0045] The regular maintenance mechanism is used to automatically add lubricant to the slide rail of the drive seat 2.

[0046] The detection and collection mechanism includes a mounting plate 401, which is fixedly connected to the outer surface of the sliding test tube 21, and the mounting plate 401 is sleeved on the outer surface of the infusion hose 3. The mounting plate 401 is fixedly connected to a guide sleeve 402 on the side away from the sliding test tube 21. A guide groove 403 is opened on one side of the guide sleeve 402, and the infusion hose 3 moves through the guide groove 403. A detection box 404 is fixedly connected to the bottom of the guide sleeve 402, and the detection box 404 is connected to the guide groove 403. The guide sleeve 402 and the guide groove 403 are both inclined. A floating valve is slidably connected in the detection box 404. Floating block 405, one side of the floating block 405 is fixedly connected to a toggle block 406, a drain port is opened on one side of the detection box 404, the detection box 404 is connected to a slide 407 through the drain port, the slide 407 slides to control the opening and closing of the drain port, one side of the slide 407 is fixedly connected to a lifting rod 408, the toggle block 406 is located below the lifting rod 408, one side of the detection box 404 is fixedly connected to a liquid guide rail 409, one side of the mounting plate 401 is fixedly connected to a collection box 410, the collection box 410 is located below the liquid guide rail 409, the upper surface of the floating block 405 is fixedly connected to a through column 4 11. The through column 411 is made of a lighter plastic material, so that when the floating block 405 pushes the through column 411 to rise, it is smoother. The top of the through column 411 is slidably connected to the top of the guide sleeve 402. A magnetic block 413 is embedded on the outer surface of the through column 411. The top of the guide sleeve 402 is slidably connected to an L-shaped slide rod 414. The detection box 404 and the through column 411 are fixedly connected to the side close to the through column 411. The bottom of the L-shaped slide rod 414 is fixedly connected to the limit rod 415. The bottom of the limit rod 415 contacts the guide sleeve 402. The mounting plate 401 A support frame 416 is fixedly connected to one side, and a curved rod 417 is rotatably connected to the bottom of the support frame 416. A second magnetic block 418 is fixedly connected to the end of the curved rod 417 near the through-column 411. The magnetic poles of the second magnetic block 418 and the first magnetic block 413 are arranged oppositely. A mounting box 419 is fixedly connected to the outer surface of the sliding test tube 21. A warning sign 420 is slidably connected to the bottom of the mounting box 419. The bottom of the warning sign 420 abuts against the curved rod 417. An alarm 421 is fixedly connected to one side of the mounting plate 401. Two electrical contacts 412 are electrically connected to control the on and off of the alarm 421.

[0047] The warning sign 420 is made of a relatively light plastic material, thereby reducing the pressure on the arc rod 417 while ensuring that the arc rod 417 can rotate.

[0048] In the prior art, since the sliding test tube 21 needs to slide up and down continuously to complete the clamping and connection of the filter tube, and the infusion tube connected to the sliding test tube 21 is generally a hose, the connection between the infusion hose 3 and the sliding test tube 21 will be constantly subjected to pressure and tension during the frequent up and down movement of the sliding test tube 21, thereby making the connection between them prone to wear. Compared with the prior art, the implementation of this embodiment avoids the problem of leakage affecting the accuracy of the test results. At the same time, through the setting of the warning sign 420, when the alarm 421 or the electrical contact 412 has a power outage or other faults, the warning sign 420 can still be unfolded and send a warning signal, thereby improving the reminder effect for the staff and ensuring the stability of the warning work.

[0049] Further examples: Please refer to Figures 8 and 9 As shown:

[0050] The regular maintenance mechanism includes a support column 501, which is fixedly connected to one side of the body 1, and a pawl 502 is rotatably connected to the end of the support column 501 away from the body 1. A connecting rod 503 is fixedly connected to one side of the drive seat 2, and a rotating shaft 504 is rotatably connected to the end of the connecting rod 503 away from the drive seat 2. The outer surface of the rotating shaft 504 is respectively fixedly connected to a ratchet 505 and a turntable 506, and the pawl 502 is meshed with the ratchet 505. The support column 501 is fixedly connected to the support rod, and the support rod abuts against the bottom of the pawl 502. Through the setting of the torsion springs on the support rod and the pawl 502, the pawl 502 can only rotate upward and cannot rotate downward, and each time it rotates, it will rotate and reset due to the action of the torsion spring. A protrusion 507 is fixedly connected to the outer surface of the turntable 506, and a fixed plate 508 is fixedly connected to one side of the body 1. The bottom of the fixed plate 508 is symmetrical The guide column is fixedly connected, and the fixed plate 508 is connected to the push plate 510 by sliding between the guide columns. The bottom of the fixed plate 508 is fixedly connected to the airbag 509, and the airbag 509 contacts the push plate 510. The airbag 509 is located between the fixed plate 508 and the push plate 510. The top of the airbag 509 is fixedly connected to a charging pipe 511, and the outer surface of the charging pipe 511 is fixedly connected to a one-way air inlet valve 512. A liquid storage box 514 is fixedly connected to one side of the body 1. A one-way air outlet valve 513 is installed on the side of the liquid storage box 514 close to the charging pipe 511. The one-way air outlet valve 513 is connected to the charging pipe 511. A U-shaped tube 515 is fixedly connected to the top of the liquid storage box 514, and a fixed tube 516 is fixedly connected to one side of the body 1. The U-shaped tube 515 is connected to the fixed tube 516. The U-shaped tube 515 passes through one end of the liquid storage box 514 and is located at the lower part of the inner cavity of the liquid storage box 514.

[0051] The friction between the rotating shaft 504 and the connecting rod 503 is relatively large, so that the rotating shaft 504 will not rotate when not subjected to external pressure, thereby ensuring that the protrusion 507 will not rotate due to gravity interference.

[0052] In the prior art, since the drive seat 2 needs to slide up and down continuously during operation, lubricating liquid is required to ensure the smooth sliding of the drive seat 2. However, the existing lubricating liquid is mostly added manually and has great instability. Compared with the prior art, the implementation of this embodiment realizes the automatic dripping of lubricating liquid, saves labor costs, and compared with traditional pumps or mechanical conveying systems, the liquid is conveyed by pneumatic pressure to avoid contact with the lubricating liquid, thereby reducing the risk of contamination of the lubricating liquid and ensuring the quality of the lubricating liquid when added.

[0053] Everything in the above example works as follows:

[0054] In the initial state: the lower end of the warning sign 420 is blocked and limited by the arc rod 417 and is located inside the installation box 419. When there is no liquid in the detection box 404, the floating block 405 is at the bottom of the detection box 404. At this time, the slide 407 is in a closed state, the two electrical contacts 412 are not in contact, and the magnetic block 1 413 and the magnetic block 2 418 have not reached the suction range. Under the limit of the limit rod 415, the L-shaped slide bar 414 cannot slide downward. An appropriate amount of lubricating liquid is stored in the liquid storage box 514, and the liquid inlet end is in a sealed state. When the push plate 510 is not affected by external force, the airbag 509 is in a normal state. Figure 8 When the ratchet wheel 505 and the pawl 502 are in the initial state of the driving seat 2, the ratchet wheel 505 and the pawl 502 are in an engaged state.

[0055] The following is the working process of the regular maintenance mechanism for automatically adding lubricant to the slide rail of the drive seat 2:

[0056] Whenever the driving seat 2 drives the sliding test tube 21 to slide up and down to complete the detection work and reset of the filter tube, the driving seat 2 will drive the rotating shaft 504, the ratchet 505 and the turntable 506 to move up and down at the same time through the connecting rod 503. When the ratchet 505 completes one up and down movement, according to the principle of the ratchet pawl 502 of the ratchet 505, each time the ratchet 505 moves downward, it is pushed by the ratchet pawl 502 to rotate a certain distance and disengage the meshing state. When the ratchet 505 moves upward, the ratchet pawl 502 will rotate so that the ratchet 505 stops rotating and re-enters the meshing state. When the drive seat 2 detects the work to a certain number of times, as the turntable 506 continues to rotate, the protrusion 507 will be driven to rotate to the top of the turntable 506, and the protrusion 507 and the push plate 510 are in a vertical state. At the same time, the protrusion 507 is closest to the push plate 510. At this time, when the drive seat 2 slides upward to reset, the connecting rod 503 and the rotating shaft 504 will The turntable 506 and the protrusion 507 are driven to move upward and reset at the same time. However, since the protrusion 507 rotates to the top of the turntable 506, the position of the protrusion 507 is perpendicular to the push plate 510. Therefore, the protrusion 507 will squeeze the push plate 510 to slide upward during the upward movement. When the push plate 510 slides upward, the push plate 510 will squeeze the airbag 509 to compress it. When the airbag 509 is compressed, the internal gas will enter the liquid storage box 514 through the pressure charging tube 511 and the one-way air outlet valve 513, so that the air pressure in the liquid storage box 514 increases, and then the increased air pressure The lubricating liquid in the liquid storage box 514 is squeezed out of the U-shaped tube 515 and enters the fixed tube 516, and then is discharged from the dripping port at the bottom of the fixed tube 516, accurately dripping onto the slideway of the drive seat 2, thereby reducing the friction of the drive seat 2 when sliding. The air pressure in the liquid storage box 514 is increased by the compression of the airbag 509, thereby realizing automatic dripping of the lubricating liquid, saving labor costs. Compared with traditional pumps or mechanical delivery systems, the liquid delivered by air pressure can avoid contact with the lubricating liquid, thereby reducing the risk of contamination of the lubricating liquid and ensuring the quality of the lubricating liquid when added.

[0057] Furthermore, when the driving seat 2 drives the turntable 506 to continue to move downward and reset, the protrusion 507 moves away from the push plate 510 again. At this time, since the push plate 510 loses the squeezing of the protrusion 507, the push plate 510 slides downward again and returns to its initial state under the influence of gravity. At the same time, the air bag 509 rebounds to its normal state. When rebounding, the gas can enter the air bag 509 from the outside through the setting of the one-way air inlet valve 512 and the one-way air outlet valve 513, thereby not changing the air pressure in the liquid storage box 514, so that the air pressure in the liquid storage box 514 is constant every time. The secondary airbag 509 will increase when compressed, thereby ensuring the stable addition of lubricating liquid, and through the arrangement of the pawl 502, the ratchet 505, the turntable 506 and the protrusion 507, the driving seat 2 can squeeze the airbag 509 once each time after detecting a corresponding number of filter tubes, avoiding the uncertainty during manual addition, preventing the waste of lubricant due to excessive addition, making the lubricant addition more regular, thereby ensuring the stability of the amount of lubricant used each time, ensuring the lubrication cycle, and reducing the frequency of manual lubrication and maintenance work.

[0058] Please refer to the above working process Figure 1 and Figures 8 and 9 .

[0059] The following is the working process of the detection and collection mechanism for detecting whether the test fluid is leaking:

[0060] Furthermore, when leakage occurs at the connection between the infusion hose 3 and the sliding test tube 21 due to wear, due to the arrangement of the guide sleeve 402, the leaked liquid will slide along the guide groove 403 toward the detection box 404 and flow into the detection box 404. Due to the entry of the test liquid in the detection box 404, the floating block 405 is affected by the buoyancy and begins to drive the through column 411 to rise. When the through column 411 rises, the through column 411 simultaneously drives the electrical contact 412 at the top of the through column 411 to approach and contact the electrical contact 412 on the L-shaped sliding rod 414. Since the electrical connection of the electrical contact 412 controls the opening and closing of the alarm 421, the alarm 421 is turned on and begins to send out an alarm signal. At the same time, when the through column 411 rises, it also drives the magnetic block 1 413 to rise, so that the magnetic block 1 413 and the magnetic block 2 418 are close to each other. Then, under the influence of the suction force of the magnetic block 1 413 on the magnetic block 2 418, the arc rod 417 rotates. When the warning sign 420 is unfolded, the warning sign 420 can also warn the staff, and then by sending out warning signals simultaneously on the warning sign 420 and the alarm 421, the staff can timely discover and make countermeasures when there is leakage at the connection between the infusion hose 3 and the sliding test tube 21, thereby avoiding the problem that the leakage affects the accuracy of the test result. At the same time, through the setting of the warning sign 420, when the alarm 421 or the electrical contact 412 has a power outage or other faults, the warning sign 420 can still be unfolded and send out a warning signal, thereby improving the reminder effect for the staff and ensuring the stability of the warning work.

[0061] When the leaked test liquid causes too much to be stored in the test box 404 too quickly, the excess test liquid will continue to push the floating block 405 and the through column 411 upward through buoyancy. At this time, through the sliding setting of the L-shaped slide bar 414, after the electrical contacts 412 are in contact, the through column 411 will still push the L-shaped slide bar 414 to slide upward, thereby preventing the pressure between the electrical contacts 412 from being too high and causing wear or damage. When the electrical contacts 412 are in contact and an alarm is sounded, due to the continuous flow of the leaked test liquid, the floating block 405 will continue to rise under the influence of buoyancy, thereby driving the toggle block 406 to continue to move upward, causing the toggle block 406 to approach the lifting rod 408 and push the lifting rod 408 to move upward, thereby causing the lifting rod 408 to drive the slide 407 to slide upward, thereby opening the drain port, and the excess test liquid will be discharged from the drain port on the test box 404 and through The liquid guide rail 409 guides the liquid into the collection box 410 to collect excess test liquid. When the excess test liquid in the test box 404 is discharged, a portion of the test liquid will remain at the bottom of the test box 404. Therefore, the floating block 405 and the through column 411 are still affected by the buoyancy, so that the electrical contact 412 is still in contact, avoiding the interruption of the alarm signal. This not only avoids the test liquid from overflowing from the guide groove 403 due to excess test liquid, but also prevents the leaked test liquid from dripping onto the body 1 or the surrounding area of the body 1, causing the body 1 or the surrounding environment of the body 1 to be slippery and affecting the test work. In addition, the collected test liquid can be reused by collecting it, saving resources and reducing the cost of using the test liquid. When the staff discovers and rushes to the inspection and maintenance, they can use a straw or other tools to extract the liquid inside the test box 404, thereby facilitating the next inspection.
