Description

Technical Field

[0001] The utility model relates to the technical field of oil field oil system dosing, in particular to a medicine barrel liquid measuring device of an oil field oil system dosing robot. Background Art

[0002] During the oilfield construction and processing 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 kept at a stable content value to ensure the stability of the production medium (oil) quality.

[0003] At present, when using liquid medicine, the liquid medicine is generally placed in a medicine barrel, and the configuration of the liquid medicine is achieved through the ratio of various agents. When in use, it is pumped out by an external pump and injected into the oil. When the liquid medicine is in use, the amount of liquid medicine in the medicine barrel needs to be monitored at all times. Traditional sensors can only detect its liquid level. However, when the liquid medicine is used, some solid medicines need to be mixed with water for a long time to facilitate subsequent use. Once the medicine is not melted and is solid, there will be errors in the ratio of each component of the liquid medicine, which affects the quality of the liquid medicine. Therefore, in response to the above problems, a medicine barrel liquid measuring device for an oilfield oil system dosing robot is proposed. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figure 1 , the utility model provides a technical solution:

[0026] A drug liquid measuring device for a drug barrel of a drug dosing robot in an oil field oil system, comprising a drug liquid tank 1 and an extraction pump 2;

[0027] An extraction pump 2 is installed at the bottom of the above-mentioned liquid medicine tank 1;

[0028] A liquid medicine measuring mechanism 3 is installed on the side of the liquid medicine tank 1;

[0029] The liquid medicine measuring mechanism 3 includes a back-blowing air pump 301, an air pipe 302, and a hollow tube 303. The output end of the back-blowing air pump 301 is connected to the air pipe 302, and the other end of the air pipe 302 is connected to the vertically arranged hollow tube 303. The side of the hollow tube 303 is connected to a horizontal tube 307 and an inclined tube 306 distributed vertically. The other ends of the horizontal tube 307 and the inclined tube 306 are connected to the liquid medicine tank 1.

[0030] A motor 4 is also fixedly connected to the top of the liquid medicine tank 1 . A stirring shaft 5 is fixedly connected to the end of the main shaft of the motor 4 . The outer side of the stirring shaft 5 is fixedly connected to stirring rods 6 that are evenly distributed.

[0031] The bottom of the hollow tube 303 is fixedly connected to a support frame 305 , and the outer side of the support frame 305 is fixedly connected to the liquid medicine tank 1 .

[0032] A one-way valve 304 is installed on the outside of the air pipe 302 .

[0033] The hollow tube 303 is made of a transparent glass plate.

[0034] The inclined tube 306 is arranged at an inclination.

[0035] At present, when using liquid medicine, the liquid medicine is generally placed in a medicine barrel, and the configuration of the liquid medicine is achieved by the ratio of various medicines. When in use, the liquid medicine is pumped out by an external pump and injected into the oil. When the liquid medicine is in use, the amount of liquid medicine in the medicine barrel needs to be monitored at all times. Traditional sensors can only detect its liquid level. However, when the liquid medicine is in use, some solid medicines need to be mixed with water for a long time to facilitate subsequent use. Once the medicine is not melted and is solid, there will be errors in the ratio of each component of the liquid medicine, which affects the quality of the liquid medicine. When in use, the device is connected to an external power supply. Through the inclined tube 306 connected to the bottom of the liquid medicine tank 1, it can be ensured that when the solid medicine is not fully melted, it is located at the bottom of the hollow tube 303 through the inclined tube 306. The hollow tube 303 is convenient for observing and measuring the ratio of the medicine, which is convenient for subsequent use. The back-blowing air pump 301 is started to drive the external air to be discharged through the air pipe 302. At this time, the bottom of the hollow tube 303 can be backwashed to ensure that the medicine flows back to the inside of the liquid medicine tank 1 for melting, thereby ensuring the quality of the liquid medicine.

[0036] In this embodiment, a one-way valve 304 is installed on the outside of the air pipe 302 to ensure that water does not flow back into the back-blowing air pump 301 through the air pipe 302, thereby ensuring normal use of the equipment. At the same time, the transparent hollow tube 303 makes it convenient for staff to observe whether there is solid medicine at the bottom of the hollow tube 303, and to facilitate the measurement of the melting condition of the medicine. The inclined tube 306 is set at an angle to facilitate the solid medicine to fall to the bottom of the hollow tube 303, which is convenient for subsequent observation work. This setting can effectively measure the melting condition of the medicine and ensure the high quality of the subsequent use of the medicine.

[0037] Example 2: This example is an improvement on Example 1. Figure 2 Specifically, the bottom of the stirring shaft 5 is fixedly connected with an extrusion plate 7, and the bottom of the extrusion plate 7 is set in an arc surface, and the bottom of the extrusion plate 7 is set in contact with the bottom of the liquid medicine tank 1.

[0038] When mixing the medicines, the stirring shaft 5 is driven to rotate by starting the motor 4, so that the stirring shaft 5 drives the stirring rod 6 to stir the water. At the same time, the squeezing plate 7 at the bottom of the stirring shaft 5 cooperates with the medicine liquid tank 1. At this time, the bottom of the squeezing plate 7 squeezes the larger unmelted medicine, which can ensure that the medicines are fully mixed.

[0039] In this embodiment, the extrusion plate 7 is flat to ensure that the extraction pump 2 can perform normal liquid extraction work. The bottom of the extrusion plate 7 is curved, which can cooperate with the bottom of the medicine tank 1 to ensure that the medicine is squeezed and crushed, thereby accelerating its melting efficiency.
