Description

Technical Field

[0001] The utility model relates to the technical field of crude oil pipeline drag reducer filling devices, in particular to a crude oil pipeline drag reducer filling device capable of automatically filling at a fixed ratio. Background Art

[0002] During long-distance crude oil pipeline transportation, a certain amount of drag reducer is usually added to the crude oil to reduce the frictional resistance between the fluid and the inner wall of the pipeline, reduce energy consumption and improve transportation capacity. Based on the changes in crude oil flow, sensors monitor and calculate the required amount of drag reducer to ensure that it is added accurately according to the preset ratio.

[0003] The common crude oil pipeline drag reducer filling device injects the drag reducer into the crude oil. Due to uneven mixing, the drag reducer is unevenly distributed in the crude oil. The drag reducer concentration is high in some areas and low in some areas, affecting the overall drag reduction effect. As a result, the friction resistance between the crude oil and the inner surface of the pipeline increases, energy consumption increases, and transportation efficiency decreases.

[0004] Therefore, for the above-mentioned crude oil pipeline drag reducer filling device, when the drag reducer is added into the crude oil, the problem of uneven distribution of the drag reducer in the crude oil may occur. An automatic fixed-ratio filling crude oil pipeline drag reducer filling device can be designed. Through the mixing plate, mixing hole, mixing semicircular inclined plate, mixing baffle, mixing through hole and mixing spiral plate, the mechanism forms a multi-level mixing, which can effectively mix the drag reducer and crude oil evenly, ensuring that the drag reducer can continue to play a role in the entire transportation process to solve the above-mentioned problem. Utility Model Content

[0005] In order to overcome the common crude oil pipeline drag reducer filling device, the drag reducer is injected into the crude oil, which may cause the drag reducer to be unevenly distributed in the crude oil.

[0006] The technical solution of the utility model is: a crude oil pipeline drag reducer filling device with automatic fixed-ratio filling, comprising a base plate; also comprising a mixing plate, a mixing hole, a mixing semicircular inclined plate, a mixing baffle, a mixing through-hole and a mixing spiral plate, two supporting frames are welded to the upper end surface of the base plate, the upper ends of the two supporting frames are fixedly connected with the drag reducer filling pipeline, the inner surface of the drag reducer filling pipeline is fixedly connected with the mixing plate, a plurality of mixing holes are opened on the surface of the mixing plate, two mixing semicircular inclined plates are welded inside the drag reducer filling pipeline, a mixing baffle is welded on the inner surface of the drag reducer filling pipeline, a plurality of mixing through-holes are opened on the surface of the mixing baffle, a connecting rod is welded on the left end surface of the mixing baffle, a mixing spiral plate is welded on the surface of the connecting rod, the mixing baffle is located on the right side of the mixing semicircular inclined plate, and the mixing semicircular inclined plate is located on the right side of the mixing plate.

[0007] Preferably, the setting of the mixing plate and the mixing hole can preliminarily break up the crude oil and the drag reducer through the mixing hole to promote their preliminary mixing with the crude oil, which can increase the turbulence of the fluid and help improve the mixing efficiency. The mixing semicircular inclined plate can guide the flow direction of the fluid and increase the collision chance between the fluids, so that the crude oil and the drag reducer are mixed and collided after being broken up, which can further promote the mixing effect. The setting of the mixing baffle and the mixing through-hole can perform secondary refinement and dispersion of the drag reducer and the crude oil, which increases the turbulence effect when the fluid passes through. The setting of the mixing spiral plate can generate a rotational motion, so that the fluid flowing through forms a vortex, so that the crude oil and the drag reducer collide with each other, further enhancing the mixing effect. The mechanism goes from the mixing hole to the mixing semicircular inclined plate, and then to the mixing baffle and the mixing through-hole thereon, and finally forms a multi-level mixing through the vortex action generated by the mixing spiral plate, which can effectively mix the drag reducer and the crude oil evenly, ensuring that the drag reducer can continue to play a role in the entire transportation process.

The setting of mixing baffles and mixing through-holes can perform secondary refinement and dispersion of the drag reducer and crude oil, which increases the turbulent effect when the fluid passes through. The setting of mixing spiral plates can generate rotational motion, so that the fluid flowing through forms a vortex, so that the crude oil and drag reducer collide with each other, further enhancing the mixing effect.

The drag reducer is broken up and then mixed and collided, which can further promote the mixing effect. The setting of the mixing baffle 25 and the mixing through hole 26 can perform secondary refinement and dispersion of the drag reducer and crude oil, which increases the turbulent effect when the fluid passes through. The setting of the mixing spiral plate 28 can generate a rotational motion, so that the fluid flowing through forms a vortex, so that the crude oil and the drag reducer collide with each other, further enhancing the mixing effect.

The mixing semicircular inclined plate 24 can guide the flow direction of the fluid and increase the collision chance between the fluids, so that the crude oil and the drag reducer are mixed and collided after being broken up, which can further promote the mixing effect. The setting of the mixing baffle 25 and the mixing through hole 26 can perform secondary refinement and dispersion of the drag reducer and the crude oil, increasing the turbulence effect when the fluid passes through. The setting of the mixing spiral plate 28 can generate a vortex. The rotating motion forms a vortex in the fluid flowing through, causing the crude oil and the drag reducer to collide with each other, further enhancing the mixing effect. The mechanism goes from the mixing hole 23 to the mixing semicircular inclined plate 24, then to the mixing baffle 25 and the mixing through-hole 26 thereon, and finally forms a multi-level mixing through the vortex effect generated by the mixing spiral plate 28, which can effectively mix the drag reducer and crude oil evenly, ensuring that the drag reducer can continue to play a role in the entire transportation process, so as to solve the common crude oil pipeline drag reducer filling device.
