[0001] The utility model relates to the technical field of chemical production, in particular to a quantitative adding and mixing device for additives. Background Art

[0002] Additives are mostly formed by a mixture of liquid and solid. The amount of liquid added needs to be adjusted according to the ratio. The liquid is sent into the tank and stirred to achieve mixing, and then a pump is used to discharge the mixed liquid.

The delivery pump 12 is a technology disclosed in the prior art, and its specific model and specifications are not limited too much here;

[0037] The static mixer 13 is fixedly installed in the cavity of the storage body 10 and is used for mixing multiple materials. The storage body 10 can be a double-layer structure, and the two-layer structure can enhance the thermal insulation effect.

The static mixer 13 is mutually connected with the chamber of the inner shell 20. The material pipe 11 and the static mixer 13 are respectively arranged on both sides of the inner shell 20. The inner bottom surface and the inner top surface of the inner shell 20 are both provided with the same separator 30, and the two adjacent separators 30 are respectively fixedly connected to the bottom surface of the inner shell 20 and the sealing cover on the top of the inner shell 20, and the plurality of separators 30 separate the premixing chamber 21 into a serpentine curved flow channel, and the separator 30 forms a rectangular plate structure, and the separator 30 is equal to the premixing chamber 21 in width, and the height of the separator 30 is less than the height of the premixing chamber 21. The design that the height of the separator 30 is lower than the premixing chamber 21 can make the separator 30 and the inner shell A gap is left between the top surface and the bottom surface of 20 for the material to flow from one side of the partition 30 to the other side. In the present embodiment, a hollow inner shell 20 is provided on one side of the static mixer 13. The liquid material fed into the storage body 10 through the material pipe 11 needs to pass through the chamber of the inner shell 20 before entering the feed port of the static mixer 13. When the material flows from the chamber of the inner shell 20 to the chamber of the static mixer 13, the material is guided and separated by a plurality of partitions 30 alternately distributed up and down. The material continuously alternates from top to bottom and from bottom to top to form a serpentine curved flow trajectory, so that in the process of the liquid flowing through the chamber of the inner shell 20 into the chamber of the static mixer 13, the liquid continuously impacts and mixes with each other to achieve the effect of premixing. The material discharged from the rightmost side of the partition 30 is fed into the static mixer 13 to be guided and mixed again, so as to achieve full and uniform mixing of the material, improve the mixing effect, reduce the burden of the static mixer 13, and reduce the phenomenon of uneven mixing due to complete reliance on the static mixer 13.

In the process of the material flowing from one side of the separator 30, the flow guidance and cutting effect of the material are increased, thereby promoting the continuous impact mixing of the material during the flow process, thereby improving the premixing effect.

[0043] The working principle of the utility model is as follows: by setting a hollow inner shell 20 on one side of the static mixer 13, the liquid material fed into the storage body 10 through the material pipe 11 needs to pass through the chamber of the inner shell 20 to enter the feed port of the static mixer 13, and when the material flows from the chamber of the inner shell 20 to the chamber of the static mixer 13, the material is guided and separated by a plurality of partitions 30 alternately distributed up and down, and the material continuously alternates from top to bottom and from bottom to top to form a serpentine curved flow trajectory, and the first flow guide 31 and the second flow guide 32 distributed in an eight-shaped shape can cut and disperse the material on one side of the partition 30, and the symmetrically arranged first flow guide 31 and the second flow guide 32 are a group, and a plurality of groups can be set on one side of the partition 30. In the process of the material flowing from one side of the partition 30, the flow guidance and cutting effect of the material are increased, thereby promoting the continuous impact mixing of the material during the flow process, and promoting the premixing effect of the material before entering the chamber of the static mixer 13.
