Problems solved by technology

Common mixing systems include H-type, Y-type, T-type and cross-type. Various fluids flow into the mixing chamber of the mixing system for mixing. Without adding a dynamic stirring system, uneven mixing is prone to occur; for Therefore, some mixing systems will add a power stirring system, but adding a stirring system requires an external power source, and second, it needs to occupy more installation space, and it will consume more cleaning time and equipment costs.
Additionally, existing mixing systems are not well suited to the physical flow characteristics of fluids

Embodiment 1

[0037] This embodiment provides a multi-fluid mixer, such as Figure 1 to Figure 3 As shown, it includes a mixing block 10; the mixing block 10 is provided with a cylindrical mixing chamber 180; the top wall and side wall of the mixing chamber 180 are respectively provided with a liquid outlet 181 and a plurality of groups of liquid inlets 182 distributed in a circle; The port 181 and the liquid inlet 182 are both communicated with the outer surface of the mixing block 10; the mixing chamber 180 is provided with a plurality of shunt vane groups corresponding to multiple groups of liquid inlets 182 one-to-one; A number of splitter vanes 11; the splitter vanes 11 are provided with a first flow channel slot 183, and two sets of second flow channel slots 184 distributed on both sides of the first flow channel slot 183; the first flow channel slot 183 and the two sets of second flow channel slots 184 is arranged along the length direction of the mixing chamber 180; the first flow c...

Embodiment 2

[0057] The present embodiment provides a multi-fluid mixer, and the same points with the first embodiment will not be repeated, but the differences are:

[0058] like Figure 4 and Figure 5 As shown, the liquid inlet 182 extends obliquely, and the central axis is perpendicular to the central axis of the mixing chamber 180; the multiple groups of liquid inlets 182 include several groups of main agent ports 187 and several groups of auxiliary agent ports 188;

[0059] The main agent port 187 includes a first front end communicating with the outer surface of the mixing block 10;

[0060] The auxiliary agent port 188 includes a second front end communicating with the outer surface of the mixing block 10;

[0061] The angle formed between the main dose port 187 and the reference line passing through the first front end and the second front end is 0°-35°, that is, the straight line L5 and the straight line OO 1 The formed angle is 0°-35°;

[0062] The angle formed between the a...

Embodiment 3

[0085] The present embodiment provides a hybrid test method, comprising the following steps:

[0086] Step S101:

[0087] Set the first working parameters of the multi-fluid mixer; wherein the first working parameters include: the main agent category, the diameter of the main agent port, the flow rate of the main agent, the flow rate of the main agent entering the mixing chamber, the pushing pressure of the main agent, and the auxiliary agent. The type of the agent, the diameter of the adjuvant port, the flow rate of the adjuvant, the flow rate of the adjuvant entering the mixing chamber, and the pushing pressure of the adjuvant;

[0088] Obtain the Reynolds number of the main agent, the Reynolds number of the auxiliary agent, the second working parameter after the main agent enters the mixing chamber, and the third working parameter after the auxiliary agent enters the mixing chamber; wherein; the second working parameter and the third working parameter are both Including: d...

Abstract

The invention relates to a multi-fluid mixer and a mixing test method. The multi-fluid mixer comprises a mixing block, wherein a columnar mixing chamber is arranged in the mixing block; the top wall and the side wall of the mixing chamber are respectively provided with a liquid outlet and a plurality of groups of liquid inlets; a plurality of splitter blade groups are arranged in the mixing chamber; the splitter blade groups comprise a plurality of splitter blades; each splitter blade is provided with a first flow passage groove and two groups of second flow passage grooves; the first flow channel grooves and the two groups of second flow channel grooves are arranged along the length direction of the mixing chamber; each first flow passage groove comprises a flow dividing groove for oblique flushing of fluid in the liquid inlet and two groups of movable grooves distributed on two sides of each flow splitter groove; and the movable grooves and the second flow passage grooves are used for allowing the divided fluid to pass through. The multi-fluid mixer has the advantages of uniform mixing, no power input, easiness in maintenance and cleaning, wide application range and the like.

Description

technical field [0001] The invention relates to the field of spraying, and more particularly, to a multi-fluid mixer and a mixing test method. Background technique [0002] Fluid proportioning and mixing systems are often an integral part of the spraying field, especially multi-component spraying. Common mixing systems include H-type, Y-type, T-type and cross-type. A variety of fluids converge into the mixing chamber of the mixing system for mixing. Without adding a power mixing system, the problem of uneven mixing is prone to occur; Therefore, some mixing systems will add a power stirring system, but adding a stirring system requires an additional power source, and requires more installation space, and consumes more cleaning time and device costs. In addition, existing mixing systems are not well adapted to the physical flow properties of fluids. Therefore, it is still necessary to further improve the existing mixing system to solve the aforementioned shortcomings. SUMM...
