Description

Technical Field

[0001] The invention relates to the technical field of composite material mixing, and in particular to a nano composite material high-efficiency mixing device and a use method thereof. Background Art

[0002] Nanocomposites are made of a matrix such as resin, rubber, ceramic and metal as a continuous phase, and modifiers such as nano-sized metals, semiconductors, rigid particles and other inorganic particles, fibers, nano-carbon tubes, etc. as a dispersed phase. The modifiers are evenly dispersed in the matrix material through appropriate preparation methods to form a composite system containing nano-sized materials. This system material is called a nanocomposite material.

[0003] At present, during the mixing and preparation process of existing composite materials, the mixing quality of nano-composite materials cannot meet the specified index requirements due to the influence of temperature and pressure factors; secondly, when mixing materials, some fillers are prone to coagulation with each other, resulting in the inability to fully and evenly mix the materials, thereby reducing the yield of nano-composite materials. Summary of the invention

[0004] The embodiment of the present invention provides a nano-composite material efficient mixing device and a method for using the same, which solves the problem of the yield and quality of the nano-composite material by real-time monitoring the temperature and pressure in the mixing container and mixing using ultrasonic technology.

[0005] In view of the above problems, the technical solution proposed by the present invention is:

[0006] A nano-composite material efficient mixing device comprises a mixing tank, wherein feeding assemblies are respectively arranged on both sides of the outer wall of the mixing tank, a stirring mechanism is installed at the top of the mixing tank, and the stirring mechanism is located between the two feeding assemblies, a pressurizing mechanism is provided at the top of the outer wall of the mixing tank, a heating mechanism is provided on the inner wall of the mixing tank, and a spacing is provided between the heating mechanism and the stirring mechanism, grooves are respectively provided on both sides of the bottom end of the mixing tank, an ultrasonic generator and an oscillator are respectively installed inside the two grooves, a discharge valve is connected to the bottom end of the mixing tank, and the discharge valve is located between the ultrasonic generator and the oscillator, a touch detection panel is embedded and installed on the outer wall of the mixing tank, and the detection end of the touch detection panel extends to the inside of the mixing tank.

[0007] In order to better implement the technical solution of the present invention, the following technical measures are also adopted.

[0008] Furthermore, the feeding assembly includes a feed hopper, a hopper cover and a locking knob. The two feed hoppers are respectively connected to the outer wall of the mixing tank. The top of the feed hopper is hinged to the hopper cover, and the locking knob is threadedly connected to the connection between the feed hopper and the hopper cover.

[0009] Furthermore, the stirring mechanism includes a sealing cover, a low-speed motor, a main shaft, a triangular plate, a plurality of stirring shafts and a plurality of through holes. The bottom end of the sealing cover is rotatably connected to the main shaft, and the outer wall of the main shaft is connected to the plurality of stirring shafts.

[0010] Furthermore, two sides of the bottom end of the main shaft are connected to triangular plates, and the outer walls of the two triangular plates are respectively provided with a plurality of the through holes.

[0011] Furthermore, a low-speed motor is installed at the top end of the sealing cover, and the output end of the low-speed motor is drivingly connected to the top end of the main shaft.

[0012] Furthermore, the pressurizing mechanism includes a vent seat and a booster pump, the vent seat is connected to the outer wall of the mixing tank, the booster pump is installed on the top of the vent seat, and the output end of the booster pump extends to the interior of the vent seat.

[0013] Furthermore, the heating mechanism includes a heat-conducting inner liner and a plurality of electric heating rods, a cavity is provided inside the heat-conducting inner liner, and a plurality of the electric heating rods are equidistantly installed inside the cavity.

[0014] Furthermore, the mixing tank comprises a tank body and a heat-insulating layer, an interlayer space is provided inside the tank body, and the interior of the interlayer space is filled with a heat-insulating layer.

[0015] Furthermore, the inner bottom end of the mixing tank is configured as a conical cylinder, a guide plate is installed on the inner wall of the conical cylinder, and a support frame is installed at the bottom end of the mixing tank.

[0016] A method for using a nanocomposite material high-efficiency mixing device comprises the following steps:

[0017] S1. Material feeding: The hopper cover is turned over to make the feeding hopper an open structure, and the matrix material and nanofiller are respectively put into the two feeding hoppers, wherein Fe-EDTA polymer is used as the matrix material and metal nanoparticles are used as the nanofiller. Then, the hopper cover is overlapped with the feeding hopper, and the locking knob is twisted to form a sealed environment inside the mixing tank;

[0018] S2. Sealing detection: The detection module built into the touch detection panel can monitor the temperature, pressure and air tightness inside the mixing tank in real time. After completing step S1, the touch detection panel is controlled to perform a threshold detection on the air tightness inside the mixing tank to ensure that the internal air tightness is kept within a specified range.

[0019] S3, stirring and mixing: by starting the low-speed motor, the output end of the motor drives the main shaft to rotate, and drives the triangular plate and the stirring shaft to rotate, so as to promote the mixing operation of the base material and the nanofiller inside the mixing tank for 2 to 3 hours. The triangular plate can be set to stir the mixed material accumulated at the bottom of the mixing tank, and the stirring shaft can be installed to stir the mixed material in the middle of the mixing tank;

[0020] S4, temperature and pressure control: During step S3, the temperature and pressure inside the mixing tank need to be monitored by using a touch detection panel, and combined with the set threshold, the electric heating rod in the heating mechanism is heated up, so that the booster pump injects pressure into the mixing tank, thereby ensuring that the mixed material is always treated at a high temperature and high pressure state;

[0021] S5, dispersion and mixing: after completing step S4, it is necessary to start the ultrasonic generator and the oscillator synchronously to perform secondary mixing on the mixed material inside the mixing tank, wherein the ultrasonic wave released by the ultrasonic generator produces a sound pressure effect to keep the mixed material dispersed, and the operation of the oscillator allows the loose mixed material to be fully mixed again;

[0022] S6, pressure relief and discharge: after completing steps S1 to S5, the discharge valve is opened to allow the fully mixed mixture to be discharged from the mixing tank along the guide plate, and the discharge valve is lifted by the support frame to discharge the mixture into the loading container.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] The coordinated use of the feeding component, stirring mechanism, heating mechanism, ultrasonic generator, oscillator and touch detection panel enables the device to regulate the internal temperature and pressure, so that the mixing quality can meet the requirements, and through the use of ultrasonic technology, it can generate shear force, so that finer particles can be dispersed, which is beneficial to improve the yield of nano-composite materials. Among them, the threshold set by the touch detection panel sends operating instructions to the electric heating rod and the booster pump respectively, prompting the electric heating rod to heat up and prompting the booster pump to inject pressure into the mixing tank, thereby ensuring that the mixture is always in a high temperature and high pressure state, and converting electrical energy into high frequency through the ultrasonic generator and oscillator. The mechanical vibration generates sound waves, which encounter different acoustic impedances when propagating through the medium, thus prompting the use of Fe-EDTA polymer as a precursor. By changing the carbonization temperature and mixing method, the loading amount and morphology of zero-valent iron are regulated to prepare nanocomposites with unique structure and performance. Due to its high specific surface area and porous structure, this type of composite material can quickly adsorb pollutants in water. At the same time, zero-valent iron provides good reducing ability, which can reduce a variety of toxic metal ions to non-toxic or low-toxic states, thereby reducing environmental pollution. Secondly, nano zero-valent iron biochar composites show excellent catalytic degradation ability and can effectively treat difficult-to-degrade organic pollutants.

In order to more clearly understand the technical means of the present invention, it can be implemented according to the contents of the specification.
