Abstract
Description
Technical Field
[0001] This utility model relates to the field of demulsibility testing technology, and in particular to a tester for the demulsibility properties of petroleum and synthetic fluids. Background Technology
[0002] Petroleum synthetic fluids are synthetic mixtures containing mineral oils and are used as coolants and lubricants, typically in industrial applications. The demulsibility of petroleum synthetic fluids is crucial to their effectiveness in use.
[0003] Demulsibility refers to the tendency of a liquid to emulsify with water. The liquid surface is exposed to water, and mechanical stimulation is applied to simulate conditions that may occur during transportation. The emulsification status, emulsification time, and degree of emulsification are observed. Based on the observation results and specified standards, the demulsibility of the liquid is evaluated. However, the viscosity of the test substance makes cleaning the container difficult and maintenance inconvenient. Incomplete cleaning significantly affects the efficiency and accuracy of subsequent emulsification testing of petroleum synthetic liquids. Therefore, we propose a petroleum and synthetic liquid demulsibility tester to solve the existing problems. Utility Model Content
[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an instrument for testing the demulsibility of petroleum and synthetic fluids.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a petroleum and synthetic liquid demulsifier, comprising a screw, a first motor, a mixing cylinder, a second motor, a cleaning tube, a travel plate, and an annular plate. A sealing sleeve is embedded in the inner wall of the upper end of the mixing cylinder, and an annular plate is rotatably installed inside the sealing sleeve. The second motor is located at the lower end of the annular plate, and a stirring shaft is located at the output end of the second motor. Stirring rods arranged in a ring array are arranged on the outer wall of the stirring shaft. A travel hole is opened inside the annular plate, and a cleaning tube is slidably inserted into the travel hole. One-way valve holes are evenly distributed on both sides of the outer wall of the cleaning tube. A gear ring is located at the upper end of the annular plate. A third motor is located on one side of the upper end of the mixing cylinder, and a gear that meshes with the gear ring is located at the output end of the third motor.
[0006] When using the petroleum and synthetic liquid demulsifier in this solution, because the ring plate rotates inside the sealing sleeve, and the toothed ring at the upper end of the ring plate meshes with the gear, the motor three drives the gear to rotate, which in turn drives the cleaning tube located inside the ring plate to rotate. Because a suction tube is inserted inside the cleaning tube, it drives the suction tube synchronous cylinder. Inside the mixing drum, the motor two operates, driving the stirring shaft to rotate and driving the stirring rod to rotate. When the petroleum and water inside the mixing drum are stirred, the cleaning tube is located above the ring plate, and the stroke hole of the connection channel with the ring plate is sealed by the closing ring, which prevents the leakage of materials inside the mixing drum and also prevents the entry of external substances.
[0007] Preferably, a suction tube is fixed inside the cleaning tube, and both the suction tube and the cleaning tube have flexible hoses at their upper ends. The flexible hoses ensure the effective use of the suction tube and the cleaning tube during rotation and lifting.
[0008] Preferably, the outer wall of the cleaning tube is fitted with a travel plate, and the travel plate is provided with screw holes and sliding sleeves.
[0009] Preferably, a motor three is provided at the upper end of the ring plate, and a screw rod rotatably inserted into a screw hole is provided at the upper end of the motor three. During use, the stroke plate provides conditions for threaded operation through the threaded installation of the screw rod and the screw hole.
[0010] Preferably, the upper end of the ring plate is provided with a guide rod that slides into the inside of the sliding sleeve, and both the screw and the guide rod are provided with limit rings at their upper ends. The guide rod slides inside the sliding sleeve, guiding the longitudinally moving travel plate, and the limit rings prevent the travel plate from completely disengaging from the screw and the guide rod, thus limiting the travel plate.
[0011] Preferably, a closing ring is fitted onto the upper outer wall of the cleaning tube, located above the one-way valve nozzle. The closing ring is situated below the stroke orifice, and its radius is larger than that of the stroke orifice. The closing ring seals the lower end of the stroke orifice, ensuring that the internal liquid flows out during the use of the mixing cylinder.
[0012] Preferably, a support frame is fitted onto the outer wall of the mixing drum, a guide plate is provided on the inner wall of the lower end of the mixing drum, a discharge pipe is provided at the lower end of the mixing drum, a feed pipe is provided at the upper end of the ring plate, and control valves are provided inside both the feed pipe and the discharge pipe. A viewing window is embedded in one side of the mixing drum, and a housing is fitted onto the outer wall of the motor and is rotatably mounted to the stirring shaft and connected to the ring plate at its upper end. The petroleum mixture and demulsified water are fed into the mixing drum through the feed pipe and discharged through the discharge pipe. When the petroleum mixture and water mixture are discharged, they are guided to the discharge pipe by the guide plate to facilitate the discharge of materials. The opening and closing of the feed pipe and the discharge pipe are controlled by the control valves. The outer wall of the motor is protected by the housing to prevent the motor from directly adhering to the materials inside the mixing drum. The demulsification state of the petroleum compound and water inside the mixing drum can be observed through the viewing window.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model delivers a petroleum mixture into a mixing cylinder, which is then covered with water. During this process, a motor drives the stirring shaft to rotate, which in turn stirs the fluid inside the mixing cylinder, simulating the use of the petroleum mixture. After mixing for a period of time, the emulsification status of the petroleum mixture is measured, and its anti-emulsification performance is assessed. After the anti-emulsification performance is measured, a cleaning liquid is delivered through a lifting and rotating cleaning pipe to uniformly rinse the inner wall of the mixing cylinder. This facilitates the maintenance of the mixing cylinder and provides a clean testing environment for subsequent testing of the anti-emulsification performance of the petroleum mixture, ensuring the accuracy of the anti-emulsification performance test.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1-5 As shown, the present invention proposes a petroleum and synthetic liquid demulsifier, which includes a screw 2, a first motor 4, a mixing cylinder 5, a second motor 10, a cleaning tube 11, a stroke plate 12 and an annular plate 26. A sealing sleeve 21 is embedded in the inner wall of the upper end of the mixing cylinder 5. An annular plate 26 is rotatably installed inside the sealing sleeve 21. The second motor 10 is provided at the lower end of the annular plate 26. A stirring shaft 6 is provided at the output end of the second motor 10. Stirring rods 7 are arranged in a ring array on the outer wall of the stirring shaft 6.
[0023] A support frame is fitted to the outer wall of the mixing cylinder 5. A guide plate 8 is provided on the inner wall of the lower end of the mixing cylinder 5. A discharge pipe 9 is provided at the lower end of the mixing cylinder 5. A feed pipe is provided at the upper end of the ring plate 26. Control valves are provided inside both the feed pipe and the discharge pipe 9. A viewing window 27 is embedded in one side of the mixing cylinder 5. A housing 25 is fitted to the outer wall of the motor 3 14 and is rotatably mounted on the stirring shaft 6 and connected to the ring plate 26 at its upper end.
[0024] Based on the implementation steps of Example 1: The petroleum synthetic liquid is transported into the mixing cylinder 5 through the feed pipe, and water with anti-emulsification properties is introduced. Then, the feed pipe is closed through the control valve, the motor 314 operates, drives the stirring shaft 6 to rotate, and drives the stirring rod 7 to stir the petroleum synthetic liquid and water. The mixing situation of petroleum synthetic liquid and water inside the mixing cylinder 5 can be observed through the viewing window 27 to simulate the use of petroleum synthetic liquid. By understanding the emulsification situation of petroleum synthetic liquid and water, the quality of petroleum synthetic liquid can be understood. The emulsified petroleum synthetic liquid and water are discharged from the mixing cylinder 5 through the discharge pipe 9.
[0025] like Figures 1-5As shown, compared with Embodiment 1, the petroleum and synthetic liquid demulsifier proposed in this utility model further includes: a stroke hole 23 is opened inside the ring plate 26, a cleaning tube 11 is slidably inserted inside the stroke hole 23, one-way valve holes 17 are opened on both sides of the outer wall of the cleaning tube 11 in an equidistant manner, a gear ring 16 is provided at the upper end of the ring plate 26, a motor 14 is provided on one side of the upper end of the mixing cylinder 5, and a gear 15 that meshes with the gear ring 16 is provided at the output end of the motor 14;
[0026] A suction tube 13 is fixed inside the cleaning tube 11, and both the suction tube 13 and the upper end of the cleaning tube 11 are provided with a flexible tube 1.
[0027] A travel plate 12 is sleeved on the outer wall of the cleaning tube 11. The travel plate 12 has screw holes 18 and sliding sleeves 19 respectively.
[0028] A motor 14 is provided on the upper end of the ring plate 26, and an internal screw 2 with a screw hole 18 is provided on the upper end of the motor 14 for rotational insertion.
[0029] The upper end of the ring plate 26 is provided with a guide rod 3 that is slidably inserted into the sliding sleeve 19, and the upper ends of both the screw 2 and the guide rod 3 are provided with limit rings 20;

[0031] In this embodiment, the output petroleum synthetic liquid and water adhere to the internal components of the mixing cylinder 5. The hose 1 is connected to both the delivery pump and the suction pump. The delivery pump delivers cleaning liquid through the hose 1 into the cleaning pipe 11. Under water pressure, the elastic valve core inside the one-way valve orifice 17 opens and outputs through the one-way valve orifice 17, spraying it into the mixing cylinder 5 to flush its interior. Simultaneously, because the stroke plate 12 slides inside the sliding sleeve 19 via the guide rod 3, when the motor 4 drives the screw 2 to rotate, it pushes the screw hole 18, thereby causing the stroke plate 12 to move longitudinally. 12 drives the cleaning tube 11 and suction tube 13 to descend and enter the mixing cylinder 5, rinsing the inside of the mixing cylinder 5 at multiple points. Motor 3 14 drives gear 15 to rotate, gear 15 pushes gear ring 16 to rotate, driving ring plate 26 to rotate. During the rotation of ring plate 26, the cleaning tube 11 rotates on the side inside the mixing cylinder 5, thoroughly rinsing the inside of the mixing cylinder 5. The mixing cylinder 5 achieves convenient and efficient cleaning, ensuring the cleanliness of the inside of the mixing cylinder 5 for subsequent testing. At the same time, during the emulsification testing process, suction tube 13 draws liquid from the inside of the mixing cylinder 5 through one-way valve nozzle 24 for staged testing.
