Description

Technical Field

[0001] This utility model relates to a rapid oil-water tester, and in particular to a blade-type electrode cleaning mechanism used in a rapid oil-water tester. Background Technology

[0002] Crude oil metering is a crucial step in oilfield production, and the measurement of water content in crude oil is a vital technical indicator for this process. Crude oil water content is typically measured using capacitance, radio frequency, conductivity, and microwave methods. These methods generally involve installing electrode probes inside the pipeline, which transmit signals to measure the water content. However, the presence of impurities such as oil, scale, and grit on the electrode surface can affect the quality of signal transmission and reception, thus reducing the accuracy of the water content measurement.

[0003] Currently, cleaning the electrode probe requires disassembling the testing instrument or manual cleaning by maintenance personnel, which greatly increases the difficulty and time required for cleaning. It is impossible to automatically clean the electrode probe during oil delivery, increasing labor costs and cleaning time. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a blade-type electrode cleaning mechanism for an oil-water rapid tester, which solves the problem that currently, when cleaning the electrode probe, it is necessary to disassemble the tester or have maintenance personnel manually clean it, which greatly increases the difficulty and time of cleaning, and cannot automatically clean the electrode probe during oil transportation, thus increasing labor costs and cleaning time.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a blade-type electrode cleaning mechanism for an oil-water rapid tester, comprising a manifold housing, an electrode probe disposed at the bottom of the manifold housing, and a self-cleaning structure that is automatically driven to rotate with the oil delivery within the manifold housing. The self-cleaning structure includes a support plate disposed on one side of a scraper shaft, with worm gear blades evenly distributed on the outer surface of the support plate. The worm gear blades are arranged at an incline on the support plate. The scraper shaft is rotatably disposed within a shaft fixing frame, which is disposed within the manifold housing. A metal scraper corresponding to the electrode probe is disposed on the scraper shaft.

[0006] As one embodiment of this application: a nylon scraper is provided on one side of the metal scraper, and the outer surface of the nylon scraper is in contact with the electrode probe. By rotating the metal scraper, the nylon scraper is driven to rotate, thereby cleaning the dirt adhering to the electrode probe.

[0007] As one embodiment of this application: the angle between the central axis of the worm gear blade and the axis of the bearing disk is 6°-8°, which can guide the liquid to flow smoothly along the blade surface, reduce turbulence generation, and improve rotational stability.

[0008] As one embodiment of this application: the inclination angle between the worm gear blade and the scraper shaft is 75°-85°, which facilitates the guidance of liquid.

[0009] As one embodiment of this application: the angle of attack of the worm gear blade (the angle between the tangent of the impact surface and the plane of rotation) is 18°-19°, which ensures that the effective force-bearing area is maximized during liquid impact, so as to obtain sufficient rotational power and avoid energy loss caused by excessive medium flow resistance.

[0010] As one embodiment of this application: an arc-shaped reinforcing part is provided on the back of the worm gear blade, and the arc-shaped reinforcing part is connected to the bearing plate to enhance the impact resistance of the root of the worm gear blade and prevent the worm gear blade from breaking due to long-term liquid impact.

[0011] As one embodiment of this application: a thin guide section is provided on one side of the worm gear blade, and a thick reinforcing section is provided on the other side, so as to ensure the overall strength of the blade while guiding the liquid.

[0012] As one embodiment of this application: a connecting sleeve is provided in the middle of the bearing plate, the connecting sleeve corresponds to the mounting hole, the mounting hole is provided in the middle of the bearing plate, a keyway is provided on the inner wall of the connecting sleeve, the keyway is engaged with a key block, and the key block is provided on the scraper shaft, which enables the bearing plate and the scraper shaft to be quickly assembled.

[0013] As one embodiment of this application: the connecting sleeve is also connected to the inner wall of the bearing plate through multiple sets of reinforcing ribs, which increases the overall strength of the connection between the connecting sleeve and the bearing plate and improves the impact resistance of the bearing plate.

[0014] As one embodiment of this application: the nylon scraper is provided with wavy serrations on the contact surface between the nylon scraper and the electrode probe to enhance the scraping effect and facilitate the scraping of dirt on the electrode surface.

[0015] The beneficial effects of this utility model are: In the process of transporting crude oil, the impact force of the crude oil drives the worm gear blades to rotate, which in turn drives the metal scraper to rotate, thereby automatically cleaning the dirt adhering to the electrode probe. This achieves automatic cleaning of the dirt on the surface of the electrode probe without the need for disassembly or manual cleaning. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All directional indicators (such as up, down, left, right, front, back, etc.) in the present utility model are only used to explain the relative positional relationship and movement of each component in a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indicator will also change accordingly.

[0019] Please see Figures 1-4A blade-type electrode cleaning mechanism for a rapid oil-water tester includes a manifold housing 5, an electrode probe 3 disposed at the bottom of the manifold housing 5, and a self-cleaning structure 1 disposed inside the manifold housing 5. The self-cleaning structure 1 includes a support plate 12 disposed on one side of a scraper shaft 16. Worm gear blades 11 are evenly distributed on the outer surface of the support plate 12 and are arranged at an incline on the support plate 12. The scraper shaft 16 is rotatably mounted inside a shaft fixing frame 15 disposed inside the manifold housing 5. The scraper shaft 16 is equipped with a mounting bracket for the electrode probe. The metal scraper 14 corresponding to the head 3, and the manifold housing 5 are respectively provided with a first flange 2 and a second flange 4 at both ends. The first flange 2 is connected to the oil inlet pipe and the second flange 4 is connected to the oil outlet pipe, which can transport crude oil liquid into the manifold housing 5. At the same time, the manifold housing 5 is also provided with a controller 6, which is connected to the electrode probe 3 and processes the data detected by the electrode probe 3. A nylon scraper 13 is provided on one side of the metal scraper 14. The outer surface of the nylon scraper 13 is attached to the electrode probe 3. By rotating the metal scraper 14, the nylon scraper 13 is driven to rotate, thereby cleaning the dirt adhering to the electrode probe 3.

[0020] Because the metal scraper 14 relies on the flow of the conveying medium as the driving force for the rotation of the turbine blades, and the metal scraper 14 relies on the friction when in contact with the electrode probe 3 to remove impurities from the surface of the electrode probe 3, it is only suitable for applications with low medium viscosity and relatively large conveying medium flow rate. The specific principle is as follows: When crude oil liquid is conveyed into the manifold housing 5, the crude oil liquid impacts the worm gear blade 11, and then the vortex blade drives the bearing disk 12 to rotate. The bearing disk 12 drives the scraper shaft to rotate, the scraper shaft drives the metal scraper to rotate, and the metal scraper rotates to drive the nylon scraper 13 to rotate. The dirt adhering to the electrode probe 3 is cleaned by the nylon scraper 13.

[0021] Please see Figure 7 as well as Figure 8 Furthermore, the position where the nylon scraper 13 contacts the inner wall of the cavity is designed to be an arc shape that matches the inner diameter of the cavity of the busbar housing 5, and is designed with a wave-like sawtooth 131 shape to enhance the scraping effect and facilitate the scraping of dirt on the electrode surface.

[0022] Furthermore, the angle between the central axis of the worm gear blade 11 and the axis of the bearing disk 12 is 6°-8°, which can guide the liquid to flow smoothly along the blade surface, reduce turbulence, and improve rotational stability.

[0023] Please see Figure 5 A thin guide section 112 is provided on one side of the worm gear blade 11, and a thick reinforcing section 111 is provided on the other side, which can ensure the overall strength of the blade while guiding the liquid.

[0024] Furthermore, the inclination angle between the worm gear blade 11 and the scraper shaft 16 is 75°-85°, which facilitates the guidance of liquid flow.

[0025] Furthermore, the angle of attack (the angle between the tangent of the impact surface and the plane of rotation) of the worm gear blade 11 is 18°-19°, which ensures that the effective force-bearing area is maximized during liquid impact, so as to obtain sufficient rotational power and avoid energy loss caused by excessive medium flow resistance.

[0026] Furthermore, an arc-shaped reinforcing part 113 is provided on the back of the worm gear blade 11. The arc-shaped reinforcing part 113 is connected to the bearing plate 12 to enhance the impact resistance of the root of the worm gear blade 11 and prevent the worm gear blade 11 from breaking due to long-term liquid impact.

[0027] In this application, the worm gear blade 11 is made of reinforced polytetrafluoroethylene (PTFE). This material combines lightweight and wear resistance, with a density only 1 / 4 that of metal, reducing rotational inertia. It is also resistant to crude oil corrosion, making it suitable for various working environments. The length of the worm gear blade 11 is 1 / 3 to 1 / 2 of the diameter of the surface cavity, and the width is 1 / 4 to 1 / 3 of the length. This dimensional ratio ensures the effective contact area between the worm gear blade 11 and the liquid, while avoiding structural interference due to excessive blade length or insufficient driving force due to excessively short blades.

[0028] Please see Figure 6 A connecting sleeve 121 is provided in the middle of the bearing plate 12. The connecting sleeve 121 corresponds to the mounting hole 125. The mounting hole 125 is located in the middle of the bearing plate 12. A keyway 124 is provided on the inner wall of the connecting sleeve 121. The keyway 124 is engaged with the key block 123. The key block 123 is located on the scraper shaft 16, which enables the bearing plate 12 and the scraper shaft 16 to be quickly assembled.

[0029] When installing the carrier plate 12, the scraper shaft 16 passes through the connecting sleeve 121 and the mounting hole 125, and the key block 123 is inserted into the keyway 124, thereby quickly installing the carrier plate 12.

[0030] Furthermore, the connecting sleeve 121 is connected to the inner wall of the bearing plate 12 through multiple sets of reinforcing ribs 122, which increases the overall strength of the connection between the connecting sleeve 121 and the bearing plate 12 and improves the impact resistance of the bearing plate 12.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
