Description

Technical Field

[0001] The present application relates to the technical field of conductive material preparation, and in particular to a graphene copper alloy sintering device. Background Art

[0002] With the rapid development of the electric power industry, infrastructure construction and household appliances, the demand and application of conductive wires are becoming more and more extensive, and higher requirements are also placed on their performance. Although traditional copper conductive wires have good conductivity, they are limited by resource scarcity and heavy weight, especially in fields such as aerospace where weight reduction is required, and cannot be used directly. Graphene, as a material with excellent conductivity and mechanical properties, is widely used in the preparation of various composite materials. Traditionally, chemical copper-plated graphene is mostly used. Graphene is used as a matrix material, and a layer of copper is deposited on its surface through a specific chemical reaction. Alkaline washing is an important step. The chemical reactivity of the alkaline solution is used to react with oil stains, impurities, etc. on the surface of the graphene to generate soluble salts or oxides, thereby removing them from the graphene surface. At the same time, the alkaline solution can also neutralize the acidic substances on the surface of the graphene, further improving its surface properties. In the preparation process of graphene copper alloy, this type of reaction needs to be carried out in a sintering device.

[0003] The existing technology still has the following problems: 1. In the process of graphene alkali washing, the existing sintering device needs to mix the graphene and the alkaline solution, heat and stir, and then filter. However, the stirring effect of the existing sintering device is poor. Graphene is prone to precipitation during stirring, resulting in uneven mixing during stirring. Uneven mixing may cause uneven distribution of the alkali solution on the graphene surface, and some areas may be excessively corroded. Uneven mixing may also cause unreacted alkali solution or other impurities to remain on the graphene surface, thereby reducing its conductivity. In addition, filtration is required after alkali washing, and the existing sintering equipment does not have the filtration function, so the filtration with the help of other tools reduces the production efficiency.

[0004] 2. The existing sintering device does not have a uniform feeding mechanism. During the feeding process, a large amount of material is usually added, and then the required raw materials are supplemented to meet the mixing ratio of the reaction raw materials to meet the production requirements. Multiple weighing and feeding wastes time, and inaccurate mixing ratios will result in incomplete graphene reaction, which will affect the use effect of graphene copper plating.

At this time, the ball 533 is kept to squeeze the bump 55, that is, when the ball 533 rotates, the bump 55 is squeezed, which facilitates the reciprocating movement of the floating plate 54 in the inner cavity of the motor 51. When the raw materials in the inner cavity of the sintering kettle 1 are mixed, the second rotating rod 525 is driven to rotate by the operation of the motor 51, and the rotation of the second rotating rod 525 drives the third bevel gear 526 to rotate. The rotation of the third bevel gear 526 drives the first bevel gear 522 to rotate on the first connecting frame 521.

[0025] See also Figure 4 , Figure 7 and Fig. 9As shown, the buffer mechanism 56 includes a buffer frame 561, a fixed rod 562 is fixedly installed on the inner wall of the buffer frame 561, and a sliding seat 563 is slidably connected to the outer surface of the fixed rod 562.

When the ball 533 passes through the protrusion 55, the buffer plate 566 returns to its original position under the elastic force of the connecting strip 564, so that the floating plate 54 moves up, and the ball 533 periodically squeezes the protrusion 55, so that the floating plate 54 can move up and down reciprocatingly, so that the bottom sediment can be shaken to break the sedimentation state of the material at the bottom of the stirring container, so that it can re-participate in the stirring process, thereby improving the mixing uniformity of the entire material. The shaking of the bottom sediment can accelerate the mixing process of the material, so that the stirring efficiency is improved. This is because the shaking can increase the contact area between the materials, thereby accelerating the interaction between the materials.

At the same time, when there is no suction filtration, the shielding cylinder 572 is used to cover the suction filter hole 575, so that the floating plate 54 slides up and down on the shielding cylinder 572 when the floating plate 54 moves downward. At this time, the rotating wheel 5766 is not lifted up.The floating plate 54 has elastic force on the slide bar 577, which drives the slide bar 577 to generate an extrusion force on the lifting frame 5764, so that the lifting frame 5764 drives the slide bar 577 to press down, ensuring that the slide bar 577 is located at the fixed bar 573 when the floating plate 54 is pressed down, and is used to store the suction filter hole 575 to avoid leakage of alkaline solution in the suction filter hole 575 when the floating plate 54 shakes up and down, that is, the floating plate 54 shakes during stirring and is stationary during suction filtration. At the same time, the suction filter hole 575 is stored in the inner cavity of the shielding tube 572 when the floating plate 54 shakes. At the same time, when the lifting frame 5764 moves upward, the limit rod 5765 as a whole produces a supporting effect on the floating plate 54. When the mixed liquid above the inner cavity of the floating plate 54 is being filtered, the overall mass of the mixture becomes lighter. At this time, if there is no rigid support effect, the supporting effect of the buffer mechanism 56 is unstable. During the graphene gold plating process, the mixture needs to be left still during filtration. The support of the limit rod 5765 replaces the flexible support of the buffer mechanism 56 to ensure the stability of the mixture above the floating plate 54 during filtration.
