Description

Technical Field

[0001] The invention relates to the field of liquid mixing devices, in particular to a liquid split-flow mixing device. Background Art

[0002] Two-component glue or multi-component glue needs to be mixed in a certain ratio before it can be used. When the liquids are mixed, there is a time difference in the opening of each switch valve corresponding to each liquid. The time error of valve opening directly affects the initial ratio. During continuous production, the ratio error due to the valve opening time difference will disappear. However, when the glue is started to be mixed, uneven mixing and large mixing ratio errors are prone to occur. Due to the error in the ratio, the viscosity of the mixed adhesive liquid is poor and cannot meet the use of the adhesive liquid. Summary of the invention

[0003] In order to solve the problem of uneven ratio caused by the valve opening time difference at the beginning of production mentioned above, the present invention provides a liquid diversion mixing device, including a main pipe body, a liquid inlet is arranged at one end and a liquid outlet is arranged at the other end, a plurality of mixing sections are arranged in the main pipe body, a flow channel partition plate is arranged in the mixing section to divide the middle cavity into a first flow channel and a second flow channel to form liquid diversion, a flow rate partition plate is arranged on the second flow channel to reduce the flow rate of the liquid in the second flow channel and form a speed difference with the liquid in the first flow channel, a plurality of holes are arranged on the flow rate partition plate, a mixing chamber is arranged behind the first flow channel, and the liquid entering the first flow channel at the rear is mixed with the liquid entering the second flow channel at the front.

[0004] Preferably, the flow channel dividing plate is configured as a cylindrical structure.

[0005] Preferably, a stirring blade is provided in the mixing chamber.

[0006] Preferably, the stirring blade is fixed in the mixing chamber.

[0007] The beneficial effects of the present invention are as follows: the present invention has reasonable structural design and is easy to use, can make two or more liquids mix more evenly, solves the ratio error of the mixed components caused by the time difference when the valve is opened and closed when the glue supply starts and ends, reduces waste and saves costs.

[0009] Figure 1 It is a schematic diagram of the overall structure of the present invention;

[0010] Figure 2 It is a schematic diagram of the structure of the flow divider of the present invention;

[0011] In the figure: 1. main pipe body; 2. mixing section; 2.1. flow channel separator; 2.2. flow rate separator; 2.3. hole; 3. first flow channel; 4. second flow channel; 5. mixing chamber; 6. stirring blade; 7. liquid inlet; 8. liquid outlet. DETAILED DESCRIPTION

[0012] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0013] Any feature of this specification, unless otherwise specified, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise specified, each feature is only an example of a series of equivalent or similar features.

[0014] like Figure 1 and Figure 2 A liquid diversion mixing device is shown, comprising a main pipe body 1, a liquid inlet 7 is provided at one end and a liquid outlet 8 is provided at the other end, a plurality of mixing sections 2 are provided in the main pipe body 1, a flow channel partition plate 2.1 is provided in the mixing section 2 to divide the middle cavity into a first flow channel 3 and a second flow channel 4 to form liquid diversion, a flow rate partition plate 2.2 is provided on the second flow channel 4 to reduce the flow rate of the liquid in the second flow channel 4 and form a speed difference with the liquid in the first flow channel 3, a plurality of holes 2.3 are provided on the flow rate partition plate 2.2, a mixing chamber 5 is provided at the rear of the first flow channel 3, and the liquid entering the rear of the first flow channel 3 is mixed with the liquid entering the front of the second flow channel 4.

[0015] The flow channel partition plate 2.1 is configured as a cylindrical structure, and the hole 2.3 is configured as a circle.

[0016] A stirring blade 6 is arranged in the mixing chamber 5 .

[0017] The stirring blade 6 is fixed in the mixing chamber 5 .

[0018] During operation, the two-component glue is transported to the liquid inlet 7 through the pump and the valve. At this time, there is an error in the opening time of each valve corresponding to each liquid, and there is an error in the actual ratio. The two-component glue is diverted from the liquid inlet 7 together. One liquid enters the mixing chamber 5 from the middle first flow channel 3 at a fast speed, and the other liquid enters the mixing chamber 5 from the second flow channel 4. Because the flow rate partition plate 2.2 blocks and slows down the flow rate, it enters the mixing chamber 5 through the hole 2.3. The two liquids form a flow rate difference, forming the advanced liquid in the second flow channel 4 and the backward liquid in the first flow channel 3. After passing through multiple groups of mixing sections 2, it flows out from the liquid outlet 8. After entering the liquid diversion mixing device, the advanced liquid and the backward liquid are mixed by the flow rate difference. The advanced liquid (due to the ratio error caused by the valve opening time difference) is mixed with the backward liquid (standard ratio liquid) to reduce the mixing ratio error. After multiple mixing sections are mixed, the output error can be greatly reduced, and at the same time, multiple liquids can be mixed more evenly, and finally discharged through the liquid outlet 8.

[0019] The mixing space 7 at the position of the liquid outlet 3 is larger than the mixing space 7 of other mixing devices.

[0020] The invention has reasonable structural design and is easy to use, and can make two or more liquids mix more evenly. When starting production, it can reduce the ratio error of liquid mixed components caused by the valve opening time difference, reduce waste and save costs.

[0021] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
