technical field

The invention relates to the technical field of fluid delivery, in particular to a gas-liquid separation delivery pump.

Background technique

At present, in various industries, it is often necessary to transport liquid media containing more gas, and the gas content in liquid media greatly affects the transmission efficiency. When the gas content reaches or exceeds 10%, the liquid cannot be transported through the hydraulic pump. Therefore, it is necessary to add a separate gas-liquid separation auxiliary equipment to separate the gas-liquid in the liquid medium before transporting. Caused the increase of conveying cost, and the structure is complicated, and the convenience of application is low.

In the above prior art, the defects such as high cost of liquid transportation, complicated structural arrangement, and low convenience of application are technical problems that need to be solved by those skilled in the art.

In an embodiment about the gas-liquid separation delivery pump, the gas-liquid separation delivery pump includes a cylindrical casing, a rotatable exhaust pipe, a spiral blade, a volute and a straight blade, and the volute is connected to the tail of the cylindrical casing. end, and communicate with each other, the first end of the cylindrical shell is provided with an input port for the input of fluid medium, and the exhaust pipe is arranged in the middle of the cylindrical shell and the volute along the longitudinal direction, and the middle here refers to the volute and the barrel. The axial position of the connected structure of the shape shell, the side wall of the exhaust pipe is provided with an air inlet hole, and the tail end of the exhaust pipe is provided with an exhaust port connected with the air inlet hole, and the exhaust port is located at the bottom of the volute. outside. The helical blade is installed on the exhaust pipe and is located in the cylindrical shell, the straight blade is installed on the exhaust pipe and is located in the volute, and the radial direction of the volute is provided with a discharge port for discharging liquid. Through the above structure, after the gas-liquid mixture mixed with gas flows into the cylindrical shell through the input port, through the rotation of the exhaust pipe, the exhaust pipe drives the helical blade and the straight blade to rotate synchronously. With the rotation of the helical blade, The gas-liquid mixture is stirred by the helical blade. On the one hand, the gas-liquid mixture generates an axially advancing force and forms an axial flow. On the other hand, the gas-liquid mixture rotates around the axial direction due to the agitation of the helical blade. The centrifugal force, with the centrifugal force, the gas-liquid mixture has a tendency to flow to the radial side, in this process, the liquid with a larger specific gravity in the gas-liquid mixture receives a greater centrifugal force than the gas with a smaller specific gravity, so , the liquid flows to the radial side, and the gas gradually converges towards the middle while moving in the axial direction. Because there is an air inlet hole on the side wall of the exhaust pipe in the middle, the gas enters the air inlet hole and continues along the Axial movement, and finally, the gas is discharged from the exhaust port. Since the exhaust port is located outside the volute, the gas is discharged from the overall space of the cylindrical casing and the volute. As for the liquid, the liquid is on the radial side, that is, along the inner edge of the cylindrical casing and gradually moves to the position of the volute. With the rotation of the straight blades, the liquid is pushed into the radial discharge of the volute by the straight blades. The gas-liquid separation delivery pump completes the delivery of the liquid. In this delivery process, the gas is separated from the gas-liquid mixture through the structural setting and the physical principle of centrifugal force, and the output is output through the discharge port of the volute. Gas in the liquid is removed. Therefore, without independent auxiliary equipment for gas-liquid separation, the application of this gas-liquid separation delivery pump can simultaneously complete the functions of transportation and gas-liquid separation, which improves the convenience of liquid transportation and reduces the Application cost and structural complexity.
