Description

Technical Field

[0001] This utility model relates to the field of dilution equipment technology, specifically to a dynamic concentration automatic adjustment dilution tank. Background Technology

[0002] The dynamic concentration automatic adjustment dilution tank is an intelligent device based on precise fluid control technology. Its core principles include: multi-channel fluid control, using a high-precision peristaltic pump or syringe pump to deliver the stock solution and mother liquor; solenoid valve switching channels to ensure accurate liquid flow direction; real-time concentration monitoring and feedback to monitor the dilution concentration online; and automatic adjustment of the flow rate ratio according to the preset target concentration to form a closed-loop control system.

[0003] The above control mainly relies on the control system algorithm. In order to ensure accurate and efficient dilution concentration, reliable hardware facilities are also required.

[0004] Most existing dilution tanks achieve dilution directly by stirring and mixing within the tank's internal stirring arm. However, dilution is a process, and the monitored concentration is inaccurate until it is completely and evenly mixed. At this point, automatic adjustment can actually affect the true concentration. Therefore, efficient mixing is a prerequisite for accurate concentration monitoring. However, the mixing efficiency of existing dilution tanks is relatively low, which makes the entire dilution process time-consuming. Thus, it is necessary to improve the mixing efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dynamic concentration automatic adjustment dilution tank, which solves the problem that the mixing efficiency of existing dilution tanks is relatively low, resulting in a time-consuming dilution process.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A dynamic concentration automatic adjustment dilution tank includes a dilution tank body, a drain pipe connected to the bottom of the dilution tank body, a mixing motor installed on the top of the dilution tank body, and a stirring rod that is connected to the mixing motor, installed on the top of the dilution tank body, and extends into the interior. A turbine stirring blade is fixed at the bottom of the stirring rod, and a spiral stirring blade is fixed below the middle part of the stirring rod. The top of the two side walls of the dilution tank body is provided with a mother liquor pipe and a return pipe, respectively. The opposite ends of the mother liquor pipe and the return pipe both penetrate and extend into the interior of the dilution tank body and are respectively connected to a dispersion pipe. Dispersion holes are uniformly provided at the bottom of the dispersion pipe. The bottom side wall of the dilution tank is connected to a static mixer via an output pipe, and a circulation pump is installed on the output pipe. The static mixer is connected to the input end of a Venturi jet injector via a connecting pipe. The output end of the Venturi jet injector is connected to a return pipe, and the input port of the Venturi jet injector is connected to a raw liquid pipe.

[0007] Preferably, the system also includes a solenoid valve and an online flow meter installed on both the mother liquid pipe and the raw liquid pipe, with the online flow meter installed upstream of the solenoid valve.

[0008] Preferably, it also includes a concentration sensor installed on the connecting tube.

[0009] Preferably, the dispersion tube is an arc-shaped large bend, and the mother liquor tube and the return tube are respectively connected to the middle of the two dispersion tubes, and the two dispersion tubes are of the same height and are symmetrically arranged.

[0010] Preferably, the diameter of the dispersion hole at the bottom of the dispersion tube corresponding to the reflux tube is smaller than the diameter of the dispersion hole at the bottom of the dispersion tube corresponding to the mother liquor tube.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention uses spiral stirring blades to drive the internal liquid to tumble and mix, while also using turbine stirring blades to increase the shearing effect on the liquid. The internal liquid is circulated through a static mixer and a Venturi jet pump. The static mixer directly mixes the liquid, while the Venturi jet pump enhances the mixing effect by applying pressure. The original liquid is also mixed and added through the Venturi jet pump. Both the mother liquor and the circulating mixture are added through the dispersion tube and sprinkled relatively evenly on the liquid surface. Combined with stirring, this achieves the goal of promoting the mixing effect through multiple means, greatly shortening the mixing time, and improving the accuracy of concentration monitoring as soon as possible. This facilitates the improvement of the efficiency of dynamic concentration automatic adjustment dilution, and solves the problem that the existing dilution tank has relatively low mixing efficiency, which leads to a time-consuming dilution process.

A turbine stirring blade 5 is fixed at the bottom of the stirring rod 4, and a spiral stirring blade 6 is fixed at the lower middle part of the stirring rod 4. The top of the two side walls of the dilution tank body 1 are respectively provided with a mother liquor pipe 7 and a return pipe 8. The opposite ends of the mother liquor pipe 7 and the return pipe 8 are both through and extended into the interior of the dilution tank body 1 and are respectively connected to a dispersion pipe 9. Dispersion holes 10 are evenly provided at the bottom of the dispersion pipe 9. The dispersion tube 9 is an arc-shaped large bend. The mother liquor tube 7 and the return tube 8 are respectively connected to the middle of the two dispersion tubes 9. The two dispersion tubes 9 are at the same height and are symmetrically arranged. The diameter of the dispersion hole 10 at the bottom of the dispersion tube 9 corresponding to the return tube 8 is smaller than the diameter of the dispersion hole 10 at the bottom of the dispersion tube 9 corresponding to the mother liquor tube 7. The bottom side wall of the dilution tank body 1 is connected to the static mixer 12 through the output pipe 11, and a circulation pump 13 is installed on the output pipe 11.

[0016] Working principle: The mixing motor 3 drives the spiral stirring blade 6 and the turbine stirring blade 5 to rotate at high speed via the stirring rod 4. The spiral stirring blade 6 causes the internal liquid to tumble and mix, while the turbine stirring blade 5 increases the shearing effect on the liquid. The circulating pump 13 drives the internal liquid to return to the dilution tank body 1 in sequence through the output pipe 11, static mixer 12, connecting pipe 14, Venturi jet 15, return pipe 8, and dispersion pipe 9. The liquid is continuously mixed as it passes through the static mixer 12. The Venturi jet 15 can improve the mixing effect when it is pressurized and jets. The original liquid is mixed and added through the Venturi jet 15 and is mixed upon addition. The mother liquor and the circulating mixture are both added through the dispersion pipe 9 and are relatively evenly sprayed on the liquid surface under the action of the evenly arranged dispersion holes 10. At this time, the mixture below is being stirred and mixed by the turbine stirring blade 5 and the spiral stirring blade 6, achieving the purpose of promoting the mixing effect through multiple means, improving the mixing efficiency, and shortening the mixing time.
