Pipeline liquid mixer

Abstract

A pipeline liquid mixer is installed in the middle of a main fluid pipeline flange and comprises an annular installation face, a plurality of blades are arranged in the middle of the annular installation face, and the blades enable main fluid flowing through the blades to form a rotation effect to generate shearing force and then to be mixed with auxiliary fluid with a certain distance away from the blades. The main fluid is mixed with the auxiliary fluid after passing through the mixer, so that the mixing resistance is low, and the mixing resistance is generally 1t under the normal flow speed; and the pressure is 10Kpa. The main fluid is quickly mixed with the auxiliary fluid under the action of shearing force, so that the main fluid and the auxiliary fluid are uniformly mixed.

[0002] After two different liquids are combined into one pipeline, they need to be mixed evenly. The commonly used pipeline mixer at present is a static mixer. Generally, two liquids are first combined and then fully mixed through the static mixer. The structure of the static mixer generally includes corrugated plate type, spiral strip type, horizontal strip type, etc. Such mixers have a certain resistance at normal flow rates (generally > 25 KPa).

[0003] For example, a new type of static mixer disclosed in CN222401000U belongs to the technical field of mixers, and includes: an inlet flange, a mixer housing is fixedly installed on the top of the inlet flange, a wave-shaped long blade rod is arranged inside the mixer housing, a rotating seat is rotatably installed at the bottom of the wave-shaped long blade rod, a connecting ring is fixedly installed at the bottom of the rotating seat, two groups of slots are opened inside the connecting ring, and installation components are arranged inside the two groups of placement slots. Two groups of placement slots are opened inside the inlet flange, which enables operators to perform equipment maintenance more conveniently and quickly, reduces potential safety risks during maintenance, improves work safety, and helps reduce the downtime of the production line and improve work efficiency. Moreover, the wave-shaped long blade rod can be adjusted or replaced at any time according to needs to meet different production processes or product requirements, greatly increasing the practicability of the device. This mixer is complex to install and has a certain resistance at normal flow rates. Summary of the Invention

[0042] When the present invention is in use, first install the pipeline liquid mixer between the flanges 6 of the main fluid pipeline and clamp it through the sealing surface 4. After installation, the main fluid with a large flow rate passes through the pipeline liquid mixer, and the main fluid begins to form a rotation effect. The secondary fluid enters the main fluid pipeline through the pipeline tee, and after mixing with the rotating main fluid, under the action of the shear force of the main fluid, the two fluids are quickly and evenly mixed.
