Description

Technical Field

[0001] The utility model relates to the technical field of graphene coating processing equipment, in particular to a stirring device for raw materials used in preparing graphene coating. Background Art

[0002] The preparation of graphene coatings typically involves several key steps: first, selecting a suitable graphite source, typically natural graphite or chemically synthesized graphite; then, converting the graphite into single-layer or few-layer graphene through methods such as chemical or mechanical exfoliation; then, combining the exfoliated graphene with a polymer coating matrix to form a composite material, typically achieved through solution mixing; and finally, curing the coating to ensure stable performance and strong adhesion. In coatings, graphene not only improves the coating's mechanical strength and wear resistance, but also enhances its electrical and thermal conductivity, making it widely used in fields such as corrosion protection, fire prevention, and electrical conductivity.

[0003] When dispersing graphene evenly in a coating matrix (such as epoxy resin or acrylic resin) to form a stable suspension, the graphene feedstock is often fed into a reactor containing a solvent or resin via a hopper. However, this loading method can easily cause the outer layer of graphene to wrap around the inner material after contact with the solution, causing agglomeration and reducing its dispersibility in the solvent or resin. The industry typically addresses this issue by extending the stirring time to ensure uniform distribution of the graphene sheets, but this can compromise processing efficiency. Utility Model Content

[0004] The present invention aims to solve, at least to a certain extent, one of the technical problems in the related art: to provide a stirring device for raw materials used in the preparation of graphene coatings, which can change the way the graphene raw materials are fed, reduce the agglomeration phenomenon that occurs during the feeding process, and ultimately shorten the overall stirring time and improve efficiency.

[0005] To this end, one purpose of the present invention is to provide a stirring device for raw materials used in the preparation of graphene coatings, which includes a support frame, a reactor mounted on the support frame, and a top cover covering the reactor, wherein a stirring mechanism is provided in the reactor, the top cover has a horizontally elongated feeding port, and the top cover is provided with a feeding mechanism for conveying graphene raw materials into the feeding port, and a motion mechanism for driving the discharge port of the feeding mechanism to translate along the length direction of the feeding port. The motion mechanism can drive the change of the position of the discharge port, so that the discharge port translates along the length direction of the feeding port, and ultimately changes the raw materials fed into the reactor from the original fixed position feeding to the linear position feeding in the projection area of ​​the feeding port, so that the graphene raw materials can be more dispersed and fall into the reactor during the entire feeding process, thereby reducing the occurrence of agglomeration.

[0006] According to an example of the present invention, the feeding port is a long strip feeding port extending in a horizontal straight line. The reciprocating movement in the straight line can make the structure of the motion mechanism simpler.

[0007] According to an example of the present invention, the motion mechanism includes an electric push rod, the fixed end of the electric push rod is connected to the top cover, the movable end of the electric push rod is fixedly connected to the feeding mechanism through a connecting block, and the electric push rod drives the feeding mechanism to move in the same direction as the length direction of the feeding port, so that the discharge port of the feeding mechanism can reciprocate along the length direction of the feeding port.

[0008] According to one example of the present invention, the top cover is provided with a guide rod, the ends of which are fixed to the top cover via mounting plates. The feeding mechanism is fixed with a guide block, which is sleeved outside the guide rod and slidably engaged with the guide rod. The guide rod can improve the stability of the reciprocating motion of the feeding mechanism and serve as a guide.

[0009] According to an example of the present invention, a limiting member for limiting the moving stroke of the feeding mechanism is provided on the guide rod.

[0010] According to an example of the present invention, the feeding mechanism includes a feeding barrel, a screw, a feeding motor and a feeding barrel, the screw is rotatably matched in the feeding barrel, the feeding motor is installed at the right end of the feeding barrel and is connected to the screw, the feeding barrel is located above the feeding barrel and is connected to the feeding barrel, and the bottom of the feeding barrel is provided with a discharge port near the left end, and the discharge port corresponds to the feeding port. The screw in the feeding barrel can stir a variety of raw materials, so that the various components of the graphene raw material put into the reactor can be fully mixed, which is suitable for the situation where the graphene raw material has multiple components, and through the rotation of the screw, the discharge efficiency of the graphene raw material sent out of the discharge port is constant, which can also make the graphene raw material uniformly put into the reactor, so that the stirred graphene raw material can be more evenly dispersed in the coating matrix.

[0011] According to an example of the present invention, the stirring mechanism includes a stirring shaft located in the reactor, a stirring blade is installed on the stirring shaft, and the reactor is provided with a main motor for driving the stirring shaft.

[0012] According to an example of the present invention, the main motor is arranged on the top cover, and the main motor and the feeding mechanism are arranged horizontally and spaced apart. The main motor is arranged on the top cover, thereby making the side wall structure of the reactor complete.

[0013] According to one embodiment of the present invention, the top cover is rotatably coupled to the reactor, and the support frame is provided with a rotary motor for driving the top cover to rotate relative to the reactor, with the rotary shaft of the rotary motor being transmission-connected to the top cover. The rotation of the top cover enables the graphene raw material introduced from the feed port to not only reciprocate along the length of the feed port but also synchronously rotate circumferentially, thereby increasing the landing area of ​​the graphene raw material within the reactor, further dispersing the graphene raw material and reducing agglomeration, thereby shortening the overall stirring time.

[0014] According to one embodiment of the present invention, the top cover is rotatably coupled to the reactor, and the support frame is provided with a rotary motor for driving the top cover to rotate relative to the reactor. The rotary shaft of the rotary motor is in transmission connection with the top cover, and the rotation direction of the top cover is the same as the rotation direction of the stirring shaft. The rotation of the top cover can further increase the rotation speed of the stirring shaft, thereby improving stirring efficiency.

[0015] The above technical solution has the following advantages or beneficial effects: First, the motion mechanism drives the discharge port in the feeding mechanism to move horizontally along the length direction of the long strip feeding port, so that the graphene raw material fed from the feeding port can be evenly dispersed in the long strip area projected by the feeding port. Compared with the existing fixed-point feeding method, the graphene raw material can be more dispersed, thereby reducing the agglomeration phenomenon and shortening the final stirring time; secondly, the feeding mechanism is equipped with a screw, so that the graphene raw material containing multiple components can be fully mixed in the feeding barrel, and the conveying speed of the graphene raw material at the discharge port can be more accurately controlled during the rotation of the screw to bring out the graphene raw material, so that the graphene raw material falling into the reactor is more evenly distributed; finally, by rotating the entire top cover, the feeding area of ​​the graphene raw material is further increased, so that the landing points of the graphene raw material can be evenly dispersed in most positions in the reactor, further reducing the agglomeration phenomenon that occurs during feeding, shortening the stirring time of the stirring shaft, and improving efficiency.

[0016] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] The stirring device for raw materials for preparing graphene coating according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0024] The utility model provides a stirring device for raw materials used in preparing graphene coatings, such as Figure 1-4 As shown, it includes a support frame 1, a reactor 2 mounted on the support frame 1, and a top cover 3 covering the reactor 2, wherein the reactor 2 is provided with a stirring mechanism, the top cover 3 has a feeding port 7 which is elongated in the horizontal direction, and the top cover 3 is provided with a feeding mechanism 8 for conveying graphene raw materials into the feeding port 7, and a motion mechanism 9 for driving the discharge port 8.5 of the feeding mechanism 8 to move horizontally along the length direction of the feeding port 7.

[0025] Specifically, the stirring mechanism includes a stirring shaft 4 , on which a stirring blade 5 is mounted. The reactor 2 is provided with a main motor 6 for driving the stirring shaft 4 .

[0026] like Figure 4 As shown, the stirring shaft is arranged vertically, and a plurality of stirring blades 5 are provided on the stirring shaft 4. The plurality of stirring blades 5 are divided into a plurality of groups of stirring blades 5 along the axial direction of the stirring shaft 4, and the plurality of stirring blades 5 in the same group are arranged along the circumference of the stirring shaft 4.

[0027] In this embodiment, since the feeding port 7 is long and the motion mechanism drives the discharge port in the feeding mechanism to perform translational movement along the length direction of the feeding port 7, the graphene raw material used for the preparation of the graphene coating will not gather at one point during the process of falling from the discharge port through the feeding port 7 into the reactor 2, but will be dispersed on a line formed by the projection of the feeding port 7 from top to bottom. As a result, the graphene raw material can be in the shape of long strips when entering the reactor 2, thereby achieving the purpose of reducing the agglomeration phenomenon.

[0028] Based on the preferred embodiment of the discharge port movement, the motion mechanism 9 drives the feeding mechanism 8 to reciprocate along the length direction of the feeding port 7. The motion mechanism 9 is configured as a reciprocating mechanism, thereby enabling the discharge port of the feeding mechanism 8 to reciprocate along the feeding port 7.

[0029] Based on the preferred movement of the discharge port 8.5 in the above embodiment, the movement mechanism 9 can drive the entire feeding mechanism 8 to move, so that the discharge port 8.5 on the feeding mechanism 8 is translated along the length direction of the feeding port 7.

[0030] Based on one of the preferred examples in which the feeding mechanism 8 moves as a whole with the motion mechanism: the feeding port 7 is a long strip-shaped feeding port 7 extending in a horizontal straight line direction.

[0031] Preferably, the motion mechanism 9 includes an electric push rod 9.1, and the end where the shell of the electric push rod 9.1 is located is a fixed end. The telescopic rod of the electric push rod 9.1 can perform telescopic movement in the axial direction. The end of the telescopic rod away from the fixed end is the movable end of the electric push rod 9.1. The fixed end of the electric push rod 9.1 is connected to the top cover 3, and the movable end of the electric push rod 9.1 is fixedly connected to the feeding mechanism 8 through the connecting block 9.2. The length direction of the electric push rod 9.1 itself is consistent with the length direction of the feeding port 7. Therefore, the moving direction of the feeding mechanism 8 driven by the electric push rod 9.1 is the same as the length direction of the feeding port 7, so that the discharge port 8.5 of the feeding mechanism 8 can perform reciprocating movement along the length direction of the feeding port 7.

[0032] In order to keep the feeding mechanism 8 stable during the reciprocating motion in the above embodiment, preferably, a guide rod 9.3 is provided on the top cover 3, and the two ends of the guide rod 9.3 are fixed to the top cover 3 through a mounting plate 9.4. A guide block 9.5 is fixed on the feeding mechanism 8, and the guide block 9.5 is sleeved on the outside of the guide rod 9.3 and slidably cooperates with the guide rod 9.3.

[0033] Specifically, the guide rod 9.3 and the electric push rod 9.1 are respectively arranged on both sides of the feeding mechanism 8.

[0034] Since the length of the feeding port 7 is fixed, if the discharge port 8.5 moves horizontally outside the feeding port 7, the raw materials will not be able to pass through the feeding port 7 and fall into the reactor 2. Therefore, it is necessary to constrain the movement of the discharge port 8.5. The improvement of this embodiment is that: a limiter is provided on the guide rod 9.3 to limit the movement of the feeding mechanism 8. Figure 4 As shown, since both ends of the guide rod 9.3 are secured to the top cover 3 via mounting plates 9.4, the guide block 9.5 can act as a limiter when it abuts against the mounting plates 9.4. Therefore, by adjusting the mounting plates 9.4, the mounting plates 9.4 and the limiter can be an integrated structure. It should be understood that this embodiment does not preclude the installation of additional limiters on the guide rod 9.3. Furthermore, additional limiters can be provided on the top cover 3 along the movement path of the feeding mechanism 8 to limit the movement of the feeding mechanism 8.

[0035] Based on the second preferred example that the feeding mechanism 8 moves as a whole with the motion mechanism: the above-mentioned feeding port 7 is an arc-shaped feeding port 7 formed by extending circumferentially along the center line of the reactor.

[0036] The motion mechanism 9 comprises an arcuate guide rail mounted on the top cover, with a slider slidably engaged thereon. A cylinder is provided on the top cover 3 to drive the slider along the arcuate guide rail. The cylinder is hinged to the top cover, and the end of the cylinder's piston rod is hinged to the slider. The cylinder's expansion and contraction enable the slider to reciprocate along the arcuate guide rail. The feeding mechanism 8 is secured to the slider, enabling its discharge port 8.5 to move along the arcuate feeding port 7, ensuring that the discharge port 8.5 always faces the feeding port 7 from top to bottom.

[0037] On the basis of the fact that the feeding mechanism 8 moves with the motion mechanism 9 in the above embodiment, the feeding mechanism 8 further includes a feeding barrel 8.1, a screw 8.2, a feeding motor 8.3 and a feeding barrel 8.4. The screw 8.2 rotates and fits in the feeding barrel 8.1. The feeding motor 8.3 is installed at the right end of the feeding barrel 8.1 and is transmission-connected to the screw 8.2. The feeding barrel 8.4 is located above the feeding barrel 8.1 and is connected to the feeding barrel 8.1. A discharge port 8.5 is provided at the bottom of the feeding barrel 8.1 near the left end, and the discharge port 8.5 corresponds to the feeding port 7.

[0038] Based on the preference for the movement of the discharge port 8.5 in the above embodiment, although the entire feeding mechanism 8 is moved with the motion mechanism 9 so that the discharge port 8.5 can move synchronously, the weight and volume of the entire feeding mechanism 8 are large, and a large amount of graphene raw materials will be temporarily retained in the feeding mechanism 8. Therefore, the solution of displacing the entire feeding mechanism 8 is bound to require a larger driving force. For this reason, the improvement of this embodiment is that: the motion mechanism 9 only drives the part of the feeding mechanism 8 where the discharge port 8.5 is located to move horizontally along the length direction of the feeding port 7, while the other parts of the feeding mechanism remain stationary. At this time, it is necessary to connect the discharge port 8.5 with the main part of the feeding mechanism with a flexible component, so as to achieve the purpose of allowing the discharge port to move while the feeding mechanism 8 body is stationary.

[0039] Specifically, the feeding mechanism 8 includes a feeding barrel 8.1, a screw 8.2, a feeding motor 8.3 and a feeding barrel 8.4. The feeding barrel 8.1 is suspended above the top cover 3, and the screw 8.2 rotates and fits in the feeding barrel 8.1. The feeding motor 8.3 is installed at the right end of the feeding barrel 8.1 and is transmission-connected to the screw 8.2. The feeding barrel 8.4 is located above the feeding barrel 8.1 and is connected to the feeding barrel 8.1. A discharge port is provided at the bottom of the feeding barrel 8.1 near the left end, and a feeding hose is connected to the discharge port. The lower end of the feeding hose extends to the position corresponding to the feeding port 7, so that the outlet of the lower end of the feeding hose serves as the discharge port 8.5, and the motion mechanism 9 drives the discharge port 8.5 to move horizontally along the length direction of the feeding port 7.

[0040] Specifically, the feeding port 7 is an elongated feeding port 7 extending in a horizontal straight line. The motion mechanism 9 includes an electric push rod 9.1, one end of which is provided with a housing of the electric push rod 9.1 and is fixed. The telescopic rod of the electric push rod 9.1 is capable of performing telescopic movement in the axial direction. The end of the telescopic rod facing away from the fixed end is the movable end of the electric push rod 9.1. The fixed end of the electric push rod 9.1 is connected to the top cover 3. The movable end of the electric push rod 9.1 is fixedly connected to the discharge port 8.5 via a connecting block 9.2, that is, the movable end of the electric push rod 9.1 is connected to the discharge port 8.5 at the lower end of the feeding hose via the connecting block 9.2. The length direction of the electric push rod 9.1 itself is consistent with the length direction of the feeding port 7. Therefore, the direction in which the electric push rod 9.1 drives the discharge port 8.5 to move is the same as the length direction of the feeding port 7, so that the discharge port 8.5 can perform reciprocating movement along the length direction of the feeding port 7. In this embodiment, since the discharge port 8.5 is connected to the discharge port of the feeding cylinder 8.1 through a feeding hose, the discharge port 8.5 is allowed to reciprocate when the feeding cylinder 8.1 is stationary.

[0041] like Figure 1 and Figure 4As shown, the main motor 6 is arranged on the top cover 3, and the main motor 6 and the feeding mechanism 8 are spaced apart in the horizontal direction. The output shaft of the main motor 6 passes through the top cover 3 and is in transmission connection with the stirring shaft 4. In the present embodiment, arranging the main motor 6 on the top cover 3 can keep the inner wall of the reactor 2 intact, and at the same time, the stirring shaft 4 and the stirring blades in the reactor 2 can be removed synchronously when the top cover 3 is removed. At the same time, the space below the reactor 2 can avoid the stirring shaft 4, so that the discharge port of the reactor 2 can be set at the bottom position of the reactor 2. It should be understood that without considering the above-mentioned beneficial effects, it is also allowed to arrange the main motor 6 on the outer wall of the reactor 2 so that the output shaft of the main motor 6 is in transmission connection with the stirring shaft in the reactor through an additional transmission component.

[0042] In the above embodiment, although the graphene raw material entering the reactor 2 is fed in a linear area through the reciprocating movement of the discharge port 8.5 on the feeding mechanism 8, thereby reducing the agglomeration of the raw material in the reactor 2, a small amount of agglomeration will still occur. In order to further improve this agglomeration phenomenon, the improvement of this embodiment is that: the top cover 3 is configured to rotate with the top of the reactor 2, and the support frame 1 is provided with a rotating motor 11 for driving the top cover 3 to rotate relative to the reactor 2, and the rotating shaft of the rotating motor 11 is transmission-connected to the top cover 3.

[0043] Specifically, if Figure 1 and Figure 3 As shown, a bracket 12 is provided on the support frame 1, the lower end of the bracket 12 is fixed to the support frame 1, the rotating motor 11 is installed on the upper end of the bracket 12, and an annular ring gear 13 is provided on the outer edge of the top cover 3. The output shaft of the rotating motor 11 is provided with a driving tooth 14 engaged with the annular ring gear 13, and the rotating motor 11 drives the annular ring gear 13 to rotate through the driving tooth 14.

[0044] Based on the above preferred transmission connection method, the rotation shaft of the rotating motor 11 and the top cover 3 can be connected by a chain drive, a belt drive, etc. in addition to the gear transmission in the above embodiment. Specifically, the chain or belt is sleeved on the top cover 3 and the rotation shaft of the rotating motor 11, and the rotation shaft of the rotating motor 11 drives the top cover 3 to rotate via the chain or belt.

[0045] An annular guide rail 10 is provided at the upper end of the reactor 2 , and the top cover 3 is slidably engaged with the annular guide rail 10 , thereby enabling the top cover 3 to rotate with the reactor 2 .

[0046] The top cover 3 rotates in conjunction with the reactor 2. The support frame 1 is provided with a rotating motor 11 for driving the top cover 3 to rotate relative to the reactor 2. The rotating shaft of the rotating motor 11 is transmission-connected to the top cover 3. The rotation direction of the top cover 3 is the same as the rotation direction of the stirring shaft 4.
