Description

Technical Field

[0001] The utility model relates to the technical field of liquid pipelines, and in particular to a liquid mixing device. Background Art

[0002] Liquid pipeline is a pipe used to transport media with fluid properties. It is a pipe with a hollow cross-section and no welds from beginning to end. It has a hollow cross-section and is widely used as a pipe for transporting fluids, such as oil, natural gas, coal gas, water and certain solid materials.

[0003] Currently, liquid pipelines on the market are mainly used to transport one medium. When two or more media need to be transported, it is not easy for the two or more media to be fully and evenly mixed in the pipeline. Mixing the two or more media before transportation can easily delay the overall progress and is inconvenient to use. Utility Model Content

[0004] The utility model provides a liquid mixing device, which solves the problems raised in the above background technology.

[0005] The technical solution of the utility model is as follows: a liquid mixing device, comprising an outer cylinder, both ends of the outer cylinder are fixedly connected to flange plates, the top of the outer cylinder is fixedly connected to a short tube, the top of the short tube is fixedly connected to a connecting flange, a Venturi inner tube is provided inside the outer cylinder, the two ends of the Venturi inner tube are respectively fixedly connected to welding plates A and welding plates B, a flow hole is opened on the surface of the Venturi inner tube, and a positioning mechanism is provided inside the outer cylinder.

[0006] The short tube is connected to the outer tube, and the short tube and the outer tube are arranged vertically. The medium injected through the short tube will enter the gap between the inner part of the outer tube and the venturi inner tube.

[0007] Both ends of the Venturi inner tube are funnel-shaped, and the diameter of the middle end of the Venturi inner tube is smaller than the diameters of the two ends of the Venturi inner tube. When the medium enters the Venturi inner tube through the left end and passes through the constriction of the Venturi inner tube, the flow rate increases and the medium passes through the constriction at an extremely high speed.

[0008] The maximum outer diameter of the Venturi inner tube is smaller than the inner diameter of the outer tube, and the Venturi inner tube can enter and exit the outer tube.

[0009] The outer walls of the welding pad A and the welding pad B are both tightly fitted to the inner wall of the outer tube, and the welding pad A and the welding pad B fit closely to the inner wall of the outer tube so as to achieve good tightness.

[0010] The positioning mechanism includes a limiting ring, a groove and an annular groove. The outer wall of the limiting ring is fixedly connected to the inner wall of the outer cylinder. The side of the limiting ring is fixedly connected to a compression spring. The groove is opened on the outer wall of the welding disk A. A telescopic spring is provided inside the groove. The inside of the groove is slidably connected to an arc block through the telescopic spring. The arc block is fixedly connected to a pull rod at one end close to the telescopic spring. The bottom of the pull rod is fixedly connected to an anti-sliding block. The annular groove is opened on the inner wall of the outer cylinder.

[0011] There are eight groups of compression springs in total. The side of the welding disk B away from the Venturi inner tube is in conflict with the eight groups of compression springs in the initial state. The eight groups of compression springs are in a compressed state in the initial state. When the eight groups of compression springs rebound, the Venturi inner tube will move to the left and move out of the outer tube.

[0012] The transverse width of the groove is equal to the transverse width of the annular groove, and one third of the arc block is located in the annular groove in the initial state. The arc block is stuck in the annular groove so that the Venturi inner tube cannot move to the left and out of the outer cylinder.

[0013] The arc surface of the arc block faces rightward, and the longitudinal depth of the groove is greater than the longitudinal length of the arc block. When the arc surface of the arc block is squeezed, it will move into the groove, and the arc block can be completely retracted into the groove.

[0014] The pull rod passes through and is slidably connected to the welding disk A, and the anti-sliding block protrudes from the inner wall of the welding disk A. The pull rod can be pulled by the anti-sliding block so that the arc block leaves the annular groove and retracts into the groove.

[0015] The working principle and beneficial effects of the utility model are as follows:

[0016] 1. The utility model is provided with components such as a short tube, a venturi inner tube, and flow holes, so that when two media enter horizontally through the left side of the outer tube and vertically through the top of the short tube respectively, when the medium entering horizontally passes through the reduced diameter of the venturi inner tube, the flow velocity increases and passes through the reduced diameter at an extremely high speed, thereby carrying the medium entering vertically into the inner wall of the outer tube and passing through the flow holes on the surface of the venturi inner tube to mix with the medium in the horizontal direction. Driven by the high flow velocity of the medium in the horizontal direction, the two media are evenly mixed to form the required mixed liquid.

[0017] 2. The utility model is provided with a positioning mechanism, so that when the Venturi inner tube is installed into the outer tube, the Venturi inner tube is positioned through the cooperation of the limit ring, eight sets of compression springs, arc blocks, ring grooves and other components. Subsequently, the welding plate A and the welding plate B can be welded to the inner wall of the outer tube, which effectively improves the accuracy of the Venturi inner tube when it is installed into the outer tube and facilitates the welding work.
