Description

Technical Field

[0001] This utility model relates to the field of quantitative addition equipment technology, and in particular to a functional additive quantitative addition equipment based on nanoscale stabilization. Background Technology

[0002] The nanoscale stable functional additive quantitative addition equipment is an intelligent device that integrates nanomaterial dispersion, steady-state maintenance, and high-precision metering. It is specifically designed for the atomic-level precise addition and long-term stability control of functional additives (such as nanoparticles, liposomes, quantum dots, etc.) in industrial production.

[0003] Currently, the quantitative addition technology for nanoscale functional additives (such as nanoparticles, carbon nanotubes, quantum dots, etc.) faces the following problems:

[0004] 1) Low quantitative accuracy: Traditional equipment (such as screw extrusion and gravity dripping) is difficult to achieve high-precision control below the milligram level;

[0005] 2) Poor dispersion stability: Nanomaterials are prone to agglomeration due to van der Waals forces or electrostatic effects, resulting in insufficient uniformity of addition. Therefore, we propose a quantitative addition device for functional additives based on nanoscale stabilization. Utility Model Content

[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0007] Specifically, the technical problem to be solved by this utility model is to provide a functional additive quantitative addition device based on nanoscale stabilization, so as to solve the existing technical problems of low quantitative accuracy and poor dispersion stability.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] A device for quantitative addition of functional additives based on nanoscale stabilization includes a pretreatment tank, a partition fixedly installed inside the pretreatment tank, the pretreatment tank being divided by the partition to form a premixing chamber and a dispersion chamber, a pretreatment device installed in the premixing chamber, the pretreatment device including a stirring assembly and an ultrasonic oscillator, and a dynamic dispersion device installed on the partition.

[0010] A quantitative control device includes a peristaltic pump installed on the pretreatment tank, a feed pipe installed at the bottom of the peristaltic pump and connected to the premixing chamber, a storage cylinder installed at the top of the peristaltic pump, a mass flow meter installed on the feed pipe, and a PID controller installed on the peristaltic pump. The peristaltic pump, the mass flow meter, and the PID controller communicate via a CAN bus.

[0011] As an improved technical solution, the bottom of the pretreatment tank is equipped with a discharge port, and the discharge port is connected to the dispersion chamber.

[0012] As an improved technical solution, the PID controller has a built-in viscosity-pressure mapping table, which can automatically adjust the pumping pressure according to the input viscosity value.

[0013] As an improved technical solution, the stirring assembly includes a stepper motor mounted on the pretreatment tank, a drive shaft vertically and rotatably mounted on the premixing chamber, the drive shaft being drivenly connected to the output shaft of the stepper motor, a stirring blade mounted on the drive shaft, and an ultrasonic oscillator mounted on the drive shaft and coaxially connected to the stirring blade.

[0014] As an improved technical solution, the dynamic dispersion device consists of several ultrasonic transducers installed on the partition plate, a dispersion tube installed on the partition plate, and a microporous ceramic coating coated on the dispersion tube.

[0015] As an improved technical solution, several ultrasonic transducers are equidistantly arranged along the axial / circumferential direction of the pretreatment tank.

[0016] As an improved technical solution, a spiral guide vane is installed on the inner wall of the dispersion tube.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are:

[0018] 1. This utility model involves injecting functional additives into a storage cylinder and then starting a peristaltic pump. The peristaltic pump then injects the functional additives from the storage cylinder into a premixing chamber through a feed pipe. Simultaneously, a mass flow meter monitors the functional additives flowing into the premixing chamber. If the amount reaches a preset threshold, the mass flow meter transmits a signal to a PID controller, which then controls the peristaltic pump to stop operating. This achieves quantitative addition of the functional additives with high accuracy, making it convenient and precise for quantitative addition of functional additives.

[0019] 2. In this invention, by starting a stepper motor, an ultrasonic oscillator, and an ultrasonic transducer, the output shaft of the stepper motor drives the drive shaft to rotate, which in turn drives the stirring blades to rotate, thus dispersing the material at high speed through centrifugation. Simultaneously, the ultrasonic oscillator separates agglomerates, and the ultrasonic transducer further disperses the material. The material then flows into the dispersion chamber through the dispersion tube, where it undergoes a third dispersion by the spiral guide vanes. During this process, the microporous ceramic coating reduces flow resistance, thereby facilitating the uniform dispersion of nanomaterials and ensuring their nanoscale stability.

[0030] Reference Figures 1-3 A device for quantitatively adding functional additives based on nanoscale stabilization is provided. This device includes a pretreatment tank 1, with a partition 101 fixedly installed inside. The pretreatment tank 1 is divided by the partition 101 to form a premixing chamber 102 and a dispersion chamber 103. A discharge port 104 is installed at the bottom of the pretreatment tank 1 and is connected to the dispersion chamber 103 to facilitate material discharge. A pretreatment device is installed in the premixing chamber 102, which includes a stirring assembly and an ultrasonic oscillator 10. The stirring assembly includes a stepper motor 7 mounted on the pretreatment tank 1, and a drive shaft 8 is vertically and rotatably mounted in the premixing chamber 102. The drive shaft 8 is connected to the output shaft of the stepper motor 7. The drive shaft 8 is equipped with a stirring blade 9. The ultrasonic oscillator 10 is installed on the drive shaft 8 and is coaxially connected with the stirring blade 9. A dynamic dispersion device is installed on the partition 101. The dynamic dispersion device consists of several ultrasonic transducers 11 installed on the partition 101, a dispersion tube 12 installed on the partition 101, and a microporous ceramic coating coated on the dispersion tube 12. Several ultrasonic transducers 11 are equidistantly arranged along the axial / circumferential direction of the pretreatment tank 1. A spiral guide plate is installed on the inner wall of the dispersion tube 12. Through centrifugal-ultrasonic synergistic deagglomeration and eddy current dispersion technology, the nanomaterials can be dispersed multiple times while ensuring nano-stabilization.

[0031] The quantitative control device includes a peristaltic pump 2 installed on the pretreatment tank 1. A feed pipe 3 is installed at the bottom of the peristaltic pump 2 and is connected to the premixing chamber 102. A storage cylinder 4 is installed at the top of the peristaltic pump 2. A mass flow meter 5 is installed on the feed pipe 3. A PID controller 6 is installed on the peristaltic pump 2. The peristaltic pump 2, the mass flow meter 5, and the PID controller 6 communicate via a CAN bus. The PID controller 6 has a built-in viscosity-pressure mapping table and can automatically adjust the pumping pressure according to the input viscosity value. By using the peristaltic pump 2 and the mass flow meter 5 together, precise and quantitative addition can be achieved.

[0032] In practical use, an appropriate amount of nanomaterials is injected into the pretreatment tank 1 through the storage cylinder 4 and the feed pipe 3. Then, functional additives are injected into the storage cylinder 4. The peristaltic pump 2 is then started. At this time, the peristaltic pump 2 injects the functional additives in the storage cylinder 4 into the premixing chamber 102 through the feed pipe 3. At the same time, the mass flow meter 5 monitors the functional additives flowing into the premixing chamber 102. If the amount of additives reaches the preset threshold, the mass flow meter 5 transmits the signal to the PID controller 6, and the PID controller 6 controls the peristaltic pump 2 to stop running, so as to achieve quantitative addition of functional additives with high quantitative accuracy. This facilitates the quantitative addition of functional additives with high quantitative accuracy.

[0033] Simultaneously, by activating the stepper motor 7, ultrasonic oscillator 10, and ultrasonic transducer 11, the output shaft of the stepper motor 7 drives the drive shaft 8 to rotate, which in turn drives the stirring blade 9 to rotate, thus performing a high-speed centrifugal primary dispersion of the material. Simultaneously, the ultrasonic oscillator 10 separates agglomerates, and the ultrasonic transducer 11 performs a secondary dispersion. The material then flows into the dispersion chamber 103 through the dispersion tube 12, where it undergoes a tertiary dispersion by the spiral guide vanes. During this process, the microporous ceramic coating reduces flow resistance, facilitating uniform dispersion of nanomaterials and ensuring their nanoscale stability. This device not only facilitates uniform dispersion of nanomaterials and ensures their nanoscale stability but also allows for the quantitative addition of additives with high precision.

[0034] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
