Description

Technical Field

[0001] The utility model relates to the technical field of medium conveying units, in particular to a gas-liquid mixed conveying pump tank unit. Background Art

[0002] The gas-liquid mixed transfer pump tank unit is a structure composed of a pump and a gas-liquid mixed transfer tank. It is widely used in oil and gas mixed transfer. It mainly utilizes the gas and liquid in the gas-liquid mixture and transports them to the gas-liquid mixed transfer tank through a pump to produce sufficient mixing, thereby performing gas-liquid mixed transfer. The gas-liquid mixed transfer pump tank unit is especially suitable for those occasions where gas blockage is not easy and gas-liquid mixed transfer can be achieved. It can improve transportation efficiency and reduce maintenance costs.

[0003] Existing medium conveying unit technology mostly uses traditional pump equipment for conveying. However, this method still has room for improvement in terms of mixing uniformity and conveying stability during use. For example, a Chinese patent discloses a "gas-liquid mixed conveying pump tank unit" with application number "CN01266975.X". When the medium input from the inlet pipe contains gas, the gas first rises in the tank until it reaches the top of the tank, so that the input medium is temporarily separated from the gas and liquid in the tank, and the liquid is discharged first; when the gas accumulates to a certain extent, due to the increase in gas pressure, part of the gas is compressed into the upper liquid layer in the flowing state and enters the outlet pipe together with the liquid for discharge, and this is continuous, achieving a gas-liquid conveying mixing effect. However, it relies on the gas rising in the tank to achieve gas-liquid separation. This process may not only lead to premature discharge of liquid, but also cause gas retention and uneven distribution, affecting the mixing efficiency. At the same time, it takes a lot of time for the gas to rise according to its own gravity. The process of separation and remixing of gas and liquid is relatively slow, which limits the conveying speed and overall efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide a gas-liquid mixed transport pump tank unit. Through the cooperation of the mixing ring and the inclined hole, when oil and gas are transported, the mixing ring is impacted. When passing through the inclined hole, the mixing ring is rotated on the rotating ring due to the impact of the oil and gas transport. Under the rotation, the oil and gas passing through are fully mixed, and then pass through the rotating blades. Under the rotation of the rotating blades, the oil and gas are fully mixed again, thereby achieving the effect of oil and gas mixed transport, and are discharged through the guide groove, ensuring uniform oil and gas mixing, and realizing multi-stage mixing of oil and gas during the transport process.

[0005] The present invention also provides a gas-liquid mixed transport pump tank unit as described above, comprising: a screw pump, wherein the screw pump is provided with a feed pipe and a connecting pipe, the other end of the connecting pipe is fixedly connected to the gas-liquid mixed transport tank, and the bottom of the gas-liquid mixed transport tank is provided with a discharge pipe; a rotating ring is provided inside the connecting pipe, a mixing ring is rotatably connected to the inner side of the rotating ring, an inclined hole is provided on the mixing ring, a motor is fixedly connected to the side surface of the gas-liquid mixed transport tank, the output end of the motor is fixedly connected to the main shaft, a rotating blade is provided on the main shaft, and a guide groove is provided on the bottom of the gas-liquid mixed transport tank.

[0008] According to the gas-liquid mixed transfer pump tank unit of the present invention, a mounting groove is provided inside the connecting pipe, and the rotating ring is fixedly connected to the mounting groove. Through the above device, the rotating ring is conveniently fixed through the mounting groove to prevent it from being covered by the medium in the connecting pipe and affecting the use effect.

[0009] According to the gas-liquid mixed transport pump tank unit of the present invention, the inclined hole penetrates the mixing ring and is inclined. With the above device, the inclined hole facilitates the transmission of the medium through the inclined hole, and due to the effect of the angle, it can rotate, thereby achieving the effect of gas-liquid transport mixing.

With the above device, the size of the rotating blades facilitates full contact with the medium, preventing the medium from being unable to be contacted.

[0012] According to the gas-liquid mixed transfer pump tank unit of the present invention, the guide trough is in an inverted truncated cone shape, and the guide trough outlet is connected to the discharge pipe. Through the above device, the medium is effectively concentrated through the guide trough, so that it can be fully discharged by the discharge pipe.

[0013] Beneficial effects

[0014] Compared with the existing technology, the gas-liquid mixed transportation pump tank unit, through the cooperation of the mixing ring and the inclined hole, impacts the mixing ring when oil and gas are transported. When passing through the inclined hole, the mixing ring rotates on the rotating ring due to the impact of the oil and gas transportation. Under the rotation, the oil and gas passing through are fully mixed, and then pass through the rotating blades. Under the rotation of the rotating blades, the oil and gas are fully mixed again, thereby achieving the effect of oil and gas mixed transportation, and are discharged through the guide groove, ensuring uniform mixing of oil and gas, and realizing multi-stage mixing of oil and gas during the transportation process.
