Description

Technical Field

[0001] The utility model relates to the technical field of oilfield construction, in particular to a medicine supply device used for adding medicine to an oil system of an oilfield. Background Art

[0002] During the oilfield construction process, it is necessary to accurately control the oil. The production medium (oil) flow data is obtained from the main pipeline system metering data source (DCS / transmitter). The dosing tank valve controls the follow-up drug supply according to the control curve set by the product, so that the demulsifier in the production medium can be at a stable content value to ensure the stability of the production medium (oil) quality.

[0003] The current dosing method is to directly discharge the liquid medicine inside the dosing tank by opening the valve for drug supply processing. However, as the liquid medicine is gradually discharged, the liquid medicine inside the dosing tank gradually decreases. It is necessary to stop the discharge and reconfigure the liquid medicine, which greatly affects the subsequent work efficiency. Therefore, in view of the above problem, a drug supply device for dosing oil system in oil field is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] A drug supply device for adding drugs to an oil field oil system comprises a drug supply tank 1, a discharge pipe 2 and a first liquid level sensor 3.

[0028] The bottom of the medicine supply tank 1 is connected to a discharge pipe 2 for discharging the medicine liquid;

[0029] A second liquid level sensor 10 and a first liquid level sensor 3 are installed on the side of the medicine supply tank 1 in an upper and lower distribution, and a separation bucket 5 fixedly connected to the inner wall of the medicine supply tank 1 is arranged between the second liquid level sensor 10 and the first liquid level sensor 3, and a first solenoid valve 6 is installed below the separation bucket 5;

[0030] The top of the medicine supply tank 1 is connected to a water pipe 7, and a second solenoid valve 9 is installed on the outside of the water pipe 7;

[0031] A medicine adding mechanism 4 is also installed above the medicine supply tank 1 .

[0032] The bottom of the water pipe 7 is connected to a cover body 8, and the bottom of the cover body 8 is hollow and concave.

[0033] The current dosing method is to directly discharge the liquid medicine inside the dosing tank by opening the valve for drug supply processing. However, as the liquid medicine is gradually discharged, the liquid medicine inside the dosing tank gradually decreases, and it is necessary to stop discharging and reconfigure the liquid medicine, which greatly affects the subsequent work efficiency. When the device is in use, an external power supply is connected, and the medicine supply tank 1 is divided into two upper and lower chambers by setting the separation bucket 5. The lower chamber can be directly used for oil addition. When the material below is in a low state detected by the first liquid level sensor 3, the first solenoid valve 6 is controlled to open by an external controller, so that the material above the separation bucket 5 can be discharged normally, and the subsequent liquid medicine configuration can be performed above the separation bucket 5 to ensure the continuous supply of liquid medicine and the normal use of the equipment.

[0034] In this embodiment, the water pipe 7 is connected to an external pump body for water transportation. After the medicine liquid is discharged above the separation bucket 5, the dosing mechanism 4 is used to add medicine, and the water pipe 7 is used to discharge the water to the top of the separation bucket 5. The water level is detected by the second liquid level sensor 10 to achieve precise proportioning. The cover body 8 is arranged facing downward, which can ensure that the water body rises slowly and ensure that the second liquid level sensor 10 accurately detects the water level and water volume.

[0035] Example 2: This example is an improvement on Example 1. Figure 2 Specifically, the drug adding mechanism 4 includes a drug injection tube 401, a motor 402 and a threaded shaft 403. The outer side of the drug injection tube 401 is fixedly connected to the drug supply tank 1. The top of the drug injection tube 401 is fixedly connected to the motor 402. The end of the main shaft of the motor 402 is fixedly connected to the threaded shaft 403. The outer side of the threaded shaft 403 is spirally connected to a threaded sleeve 404. The bottom of the threaded sleeve 404 is fixedly connected to an extrusion plate 405.

[0036] The bottom of the injection tube 401 is connected to a liquid discharge tube 407 , and the side of the injection tube 401 is connected to a liquid inlet tube 409 .

[0037] A sealing plate 406 is fixedly connected to the bottom of the extrusion plate 405 . The outer side of the sealing plate 406 is in close contact with the inner wall of the injection tube 401 . The sealing plate 406 is made of a rubber plate.

[0038] A first one-way valve 408 is installed on the outer side of the liquid discharge pipe 407 , and a second one-way valve 410 is installed on the outer side of the liquid inlet pipe 409 .

[0039] When configuring the liquid medicine, the bottom of the cover body 8 is located at the bottom, and the water level can be detected by the second liquid level sensor 10, and the dosing mechanism 4 can add materials. At this time, the cover body 8 extends below the water surface to add water, which can avoid causing water ripples and ensure accurate water. At the same time, the squeezing plate 405 drives the sealing plate 406 to move, and at this time, the medicine inside the injection tube 401 can be discharged through the drain pipe 407 to achieve accurate configuration of the liquid medicine; the first one-way valve 408 and the second one-way valve 410 can ensure that the medicine can only flow in one direction, and ensure that when the medicine is added to the injection tube 401, automatic extraction and discharge can be achieved;

[0040] In this embodiment, when adding medicine, the motor 402 drives the threaded shaft 403 to rotate, the threaded shaft 403 drives the threaded sleeve 404 to move, and the threaded sleeve 404 can drive the extrusion plate 405 and the sealing plate 406 to move. The extrusion plate 405 is arranged in a rectangular shape. At this time, the extrusion plate 405 can be ensured to move downward stably, and the movement of the sealing plate 406 can ensure that the medicine is smoothly discharged through the discharge pipe 407. At the same time, when the extrusion plate 405 is reset, it can add medicine through the liquid inlet pipe 409.
