The mixer is the main equipment for gas-liquid and liquid-liquid mixing in water treatment and other industries. The current mixer is mainly a traditional pipeline static mixer. Its mixing effect is not average. For example, in the air flotation treatment process of water treatment, the diameter of the bubbles generated by the traditional mixer is generally about 180 μm, which is too large, resulting in poor air flotation effect. Furthermore, the material cost of the traditional mixer is relatively high, and it is difficult to manufacture and shape it.

Utility model content:

The purpose of this utility model is to overcome the above-mentioned disadvantages of the prior art and provide a fast mixer.

The technical scheme adopted by the utility model is: a fast mixer, including a mixer cylinder, the two ends of the mixer cylinder are respectively an inlet joint and an outlet joint, and are respectively provided with an inlet flange and an outlet flange, and the mixer cylinder Deflectors are respectively installed inside the two ends of the body, wherein: a central disturbance tube is installed in the middle of the mixer cylinder, and N-level rotating flow holes are arranged on the tube wall of the central disturbance tube, and N≥3, each level The arrangement range of the rotating orifice is 360/N degrees.

The arrangement angles of adjacent stages of rotating orifices in the central disturbing tube are adjacent along the axial direction of the central disturbing tube, and the total area of each stage of rotating orifices in the central disturbing tube is the effective cross-sectional area of the inlet end of the mixer cylinder 1.5 to 2.0 times of that.

A feed nozzle is provided on the inlet joint of the mixer cylinder.

The deflector and the central disturbing tube are assembled into a whole through a guide rod and a certain distance cylinder, and then the whole is installed in the mixer cylinder.

The total area of the guide holes on each guide plate is 1.0 to 2.0 times the effective cross-sectional area of the inlet connection.

The utility model fast mixer is simple to manufacture, low in cost, reasonable in design, good in mixing effect, free of flow dead angles, and convenient in installation. It is designed with the principle of fluid mechanics, the water flow channel is smooth, and the speed gradient of the water flow is used to make the mixed liquid form violent Swirl flow and turbulent flow can produce eddy flow phenomena such as forward rotation, reverse rotation, expansion, and shrinkage, so that the added medicine and water or air and water can be quickly and fully mixed, with good mixing effect, no clogging phenomenon, no short flow phenomenon, hydraulic power Small loss, short mixing time and other advantages.

Fig. 1 is the sectional structure schematic diagram of a kind of embodiment of the utility model;

Fig. 2 is a structural schematic diagram of the central disturbance tube in the utility model;

Fig. 3 is a schematic cross-sectional structure diagram of another embodiment of the present invention.

Detailed ways:

Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.

As shown in Fig. 1 and Fig. 2, the fast mixer described in the utility model includes a mixer cylinder 1, the two ends of the mixer cylinder 1 are respectively an inlet nozzle 2 and an outlet nozzle 3, and inlet flanges are respectively provided. 21 and outlet flange 31, deflectors 4 are respectively installed inside the two ends of the mixer cylinder 1, wherein: the middle part of the mixer cylinder 1 is equipped with a central disturbance tube 5, and the tube wall of the central disturbance tube 5 There are N stages of rotating orifices 50, and N≥3, and the arrangement range of each stage of rotating orifices 50 is 360/N degrees.

The arrangement angles of adjacent stages of rotating orifices 50 in the central disturbing tube 5 are adjacent along the axial direction of the central disturbing tube 5 , and the total area of each stage of rotating orifices 50 in the central disturbing tube 5 is 2 1.5 to 2.0 times the effective cross-sectional area.

Specifically, the central disturbance tube 5 is divided into at least three sections along the axial direction, and several rotating flow holes 50 are arranged in a certain angle range on each section. The arrangement range of the rotating orifice 50 is 120°, that is, the rotating orifice is set within 120° along the circumference of the pipe wall, and the rotating orifice of the next section is adjacent to the rotating orifice of the previous section, which is also set within the range of 120°, and so on , that is, the range of all stages of rotating orifices should be 360°. In this embodiment, the deflector 4 and the central disturbance tube 5 are fixed inside the mixer cylinder 1 by welding.

The inlet joint 2 of the mixer cylinder 1 is provided with a feeding nozzle 22, that is, the medicament or gas to be mixed is added into the main flow through the feeding nozzle 22.

As shown in Fig. 2 again, in another kind of embodiment, several baffles 4 and the central disturbing tube 5 are assembled into a whole by a guide rod 6 and several spacers 7, and then this whole is installed on Inside the mixer barrel 1 , the assembly and disassembly of the deflector 4 and the central disturbance tube 5 are more convenient, and the deflector 4 is arranged at the front end and the rear end of the central disturbance tube 5 .

The total area of the diversion holes on each deflector 4 is 1.0-2.0 times the effective cross-sectional area of the inlet joint 2 .

Using the utility model, when the liquid-liquid or liquid-gas is mixed, the axial mixing occurs when passing through the front deflector 4 first, then the radial mixing through the central disturbing tube 5, and then the rear deflector The axial mixing produces vortex and reverse vortex, so that the fluid can be fully mixed instantaneously. The mixing time of the utility model is short, and the general mixing time is 1.5-2.5s.

In summary, the utility model fast mixer is simple to manufacture, low in cost, reasonable in design, good in mixing effect, free of flow dead ends, and easy to install. The mixed liquid forms violent vortex and turbulent flow, and produces vortex phenomena such as forward rotation, reverse rotation, expansion, and contraction, so that the added medicament and water or gas and water are quickly and fully mixed, with good mixing effect, no clogging, and no leakage. Short flow phenomenon, small hydraulic loss, short mixing time, etc., can be widely used in water treatment, petroleum, chemical, printing and dyeing, pharmaceutical, leather, paint, paint, alcohol, wine, paper, food and other industries.
