Description

Technical Field

[0001] The present invention relates to the technical field of oil-water separation detection, and in particular to an oil-water separation time detection device and method. Background Art

[0002] In the existing oil-water separation technology, the oil-water mixture sample is injected into a measuring cylinder and stirred at high speed to become an emulsified state. After the stirring stops and the mixture is left to stand for a period of time, the oil and water will separate. The time to detect the oil-water separation is a key parameter. Traditional oil-water separation time detection methods usually rely on visual observation or simple physical markings. These methods are not only low in accuracy, but also easily affected by human factors. In addition, existing detection devices are often complex in structure, inconvenient to operate, and difficult to achieve real-time monitoring and data recording.

[0003] Specifically, the traditional oil-water separation time detection device has the following problems: 1. Insufficient accuracy: Visual observation and simple marking methods cannot provide accurate time data.

[0004] 2. Complex operation: The complex mechanical structure and operation steps increase the difficulty of use and maintenance cost.

[0005] 3. Poor real-time performance: It is impossible to monitor the resistance changes during the oil-water separation process in real time, resulting in untimely data collection.

[0006] 4. Poor sealing: The existing devices have defects in sealing performance and are easily disturbed by the external environment. Summary of the invention

[0007] In view of the shortcomings of the prior art, the present invention provides an oil-water separation time detection device. In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: An oil-water separation time detection device includes a resistance tester, which uses a direct current circuit to measure resistance values, and also includes a measuring cylinder, a plurality of guide pins, a connector and a plug. The top of the measuring cylinder is provided with an opening, and the side wall of the measuring cylinder is evenly provided with a plurality of mounting holes arranged up and down. The guide pin is fixedly connected with a plunger that matches with the mounting hole from the inside of the measuring cylinder, and both ends of the guide pin extend out of the plunger. The connector connection includes a sealing plug and a conductive column. The sealing plug matches with the mounting hole from the outside of the measuring cylinder. At least one of the sealing plug and the plunger is used to seal the mounting hole. The conductive column is fixed in the sealing plug and corresponds to the guide pin, and both ends of the conductive column extend out of both ends of the sealing plug. When the sealing plug and the plunger match with the mounting hole, the guide pin contacts the conductive column. The two poles of the resistance tester are respectively connected with the conductive columns outside two different sealing plugs to measure the resistance value change between the corresponding guide pins. The plug is used to seal the remaining mounting holes.

[0008] Furthermore, the mounting hole and the sealing plug or the plunger are provided with a matching slot structure.

[0009] Furthermore, the mounting hole is provided with a convex ring, the sealing plug is provided with a groove, and the sealing plug is made of elastic insulating material.

[0010] Furthermore, the end of the sealing member is provided with a symmetrical recessed portion.

[0011] Furthermore, the plunger adopts a stepped structure, and the reduced boss matches the mounting hole.

[0012] Furthermore, the plunger is made of elastic insulating material.

[0013] Furthermore, the guide pin and the conductive column adopt a plug-in structure.

[0014] Furthermore, a conductive baffle is fixedly connected to the conductive post, and the baffle abuts against the end of the guide needle when the conductive post cooperates with the guide needle.

[0015] Furthermore, a nut is fixedly connected to the electrode end of the resistance tester, and the nut is threadedly connected to the conductive column.

[0016] A method for detecting oil-water separation time, using the detection device as described above, comprises the following steps: S1. The number and position of the guide pins can be predetermined according to the approximate boundary position of the oil-water mixture, ensuring that the boundary position falls between the two guide pin loops, and the remaining mounting holes are sealed with plugs; S2. Pour the oil-water mixture to be tested into a measuring cylinder, making sure that the top opening of the measuring cylinder is closed; S3. Select a guide needle at a suitable position according to the amount of the oil-water mixture, and install it in the corresponding mounting hole on the side wall of the measuring cylinder through a plunger; S4. Use the connector to install the sealing plug and the conductive column on the mounting hole, ensuring that the guide pin is in contact with the conductive column; S5. Connect the two electrodes of the resistance tester to the conductive posts outside two different sealing plugs to form a closed circuit; S6, start timing, and monitor the resistance value change displayed by the resistance tester in real time; S7. When the resistance value reaches the preset threshold, the current time is recorded, which is the time required for oil-water separation; S8. After the experiment, dismantle the device, clean and properly store all components.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1.

Strong flexibility: There are multiple mounting holes evenly arranged on the side wall of the measuring cylinder. The number and position of the guide needles can be determined according to the approximate boundary position of the oil-water mixture, so that the boundary position is located between the two guide needle loops to meet different detection requirements; 6. Easy to maintain: Each component of the device is designed as an independent modular system, which is convenient for disassembly and maintenance, reducing the cost of long-term use.
