Description

Technical Field

[0001] The invention relates to the technical field of graphene powders, in particular to a graphene powder premixing stirring kettle. Background Art

[0002] When preparing graphene coatings, it is necessary to first mix graphene powder with solvents, etc., then grind them into slurry, and then mix them with other fillers to make graphene coating products. However, due to the low density of graphene, it is easy to float above the liquid surface and is not easy to penetrate into the solution; the hardness of graphene is average, but the toughness is relatively high.

[0003] When using a stirring kettle for mixing, it is difficult to break up and mix the graphene. During the mixing process, a large amount of graphene floats on the liquid in the stirring kettle and is not easy to be stirred, which seriously limits the production efficiency. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a premixing stirring kettle for graphene powder, which ensures the mixing of graphene by specifically crushing the graphene and avoids affecting the production efficiency.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a premixing and stirring kettle for graphene powder, comprising a premixing and stirring kettle mechanism for stirring graphene materials, a rotating extrusion mechanism for rotating and extruding, and an extrusion and crushing mechanism for extrusion and crushing, wherein an outer shell is arranged inside the premixing and stirring kettle mechanism, the premixing and stirring kettle mechanism is fixedly connected to the rotating extrusion mechanism through the inner wall of the outer shell, and the premixing and stirring kettle mechanism is fixedly connected to the extrusion and crushing mechanism through the inner bottom of the outer shell.

[0006] Preferably, the premixing stirring kettle mechanism comprises a shell, an inlet and a motor, the top of the shell is provided with an inlet, and the top of the shell is fixedly connected with a motor.

[0007] Preferably, the rotary extrusion mechanism includes a first spiral plate, a rotating plate and a pressing thorn. The motor is rotatably connected to a rotating shaft at the axis center. The motor is rotatably connected to the first spiral plate through a set rotating shaft. The outer wall of the first spiral plate is fixedly connected to the rotating plate, and the bottom of the first spiral plate is fixedly connected to the pressing thorn.

[0008] Preferably, a plurality of squeezing rods are fixedly connected to the bottom of the pressing thorns, a snap-in thorn is fixedly connected to the bottom of the squeezing rods, a squeezing ball is fixedly connected to the end of the squeezing rods, and a pop-up plate is provided inside the shell.

[0009] Preferably, the extrusion and crushing mechanism includes a second spiral plate, a crushing plate and a slot, the second spiral plate is fixedly connected to the inner bottom of the shell, the pop-up plate is fixedly connected to the bottom of the second spiral plate, the outer wall of the second spiral plate is provided with two slots, and the top of the second spiral plate is located at the position of the slot and is fixedly connected with two crushing plates.

[0010] Preferably, two protruding balls are fixedly connected to the top of the second spiral plate, a spiral rod is fixedly connected to the inner bottom of the shell, a plurality of holes are formed on the outer wall of the spiral rod, and the spiral rod is made of metal material.

[0011] The present invention provides a graphene powder premixing stirring kettle, which has the following beneficial effects: 1. The graphene powder premixing stirring kettle is squeezed by the first spiral plate and the second spiral plate. As the first spiral plate rotates, the fitting strength between the first spiral plate and the second spiral plate becomes higher and higher, and the pressure on the graphene gradually becomes greater and greater, ensuring the crushing of the graphene. Moreover, when the bottom of the first spiral plate moves out of the top of the second spiral plate, the second spiral plate and the first spiral plate bounce up under their respective elasticity, increasing the impact force on the graphene, ensuring the processing of the graphene, and the spiral setting of the first spiral plate can process the graphene floating on the top of the liquid.

[0012] 2. In the premixing stirring kettle of the graphene powder, when the first spiral plate and the second spiral plate are pressed against each other, the graphene is stuck in the slot, and the crushing plate is squeezed to cut the graphene, thereby ensuring the splitting of the graphene, and the pressing thorns cut the graphene, and cooperate with the protruding balls to further cut the graphene. When the first spiral plate is active, the inserted thorns under the squeezing rod will also cut into the graphene, causing cracks in the graphene, thereby ensuring the processing of the graphene.

[0013] 3. The graphene powder premixing stirring kettle rotates the internal liquid by rotating the rotating plate, causing the graphene deposited at the bottom of the liquid to shake, thereby ensuring the complete stirring of the graphene. The spiral rod follows the shaking to stir the graphene and the liquid, thereby ensuring the mixing of the graphene. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In this embodiment, the upper end of the first spiral plate 21 is located above the liquid, and the graphene floating on the liquid is pressed to the bottom of the first spiral plate 21. The first spiral plate 21 and the second spiral plate 31 squeeze each other, so that the graphene is gradually worn.

[0026] Specifically, the extrusion and crushing mechanism 3 includes a second spiral plate 31, a crushing plate 32 and a slot 33. The second spiral plate 31 is fixedly connected to the inner bottom of the outer shell 11, the pop-up plate 27 is fixedly connected to the bottom of the second spiral plate 31, and two slots 33 are provided on the outer wall of the second spiral plate 31. The top of the second spiral plate 31 is located at the position of the slot 33 and is fixedly connected with two crushing plates 32.

[0027] In this embodiment, the pressing barb 23 cuts the graphene when following the movement of the first spiral plate 21 , and the squeezing rod 25 intercepts the graphene when following the movement of the first spiral plate 21 .

[0029] In this embodiment, when the graphene is compressed by the first spiral plate 21 , the graphene is inserted into the card slot 33 , and the crushing plate 32 is pressed down by the first spiral plate 21 to break the graphene.

[0030] When in use, the graphene to be stirred and the required liquid are added into the housing 11 through the inlet 12. The height of the liquid is half the depth of the housing 11. The motor 13 drives the first spiral plate 21 to rotate through the rotating shaft. The first spiral plate 21 gradually clamps and rubs on the second spiral plate 31, and the graphene is squeezed. The upper end of the first spiral plate 21 is located above the liquid, and the graphene floating on the liquid is pressed to the bottom of the first spiral plate 21.

After the end of the first spiral plate 21 moves from the top of the second spiral plate 31, the elasticity of the first spiral plate 21 and the second spiral plate 31 will cause the first spiral plate 21 and the second spiral plate 31 to bounce up violently, increasing the impact force of the pressing spikes 23 and the protruding balls 36 on the graphene, making the graphene easier to be broken. The first spiral plate 21 drives the rotating plate 22 to rotate during the rotation process. The rotating plate 22 can drive the stirring of the internal liquid, so that the graphene deposited at the bottom of the liquid rotates. Finally, under the gathering force of the liquid rotation, most of the graphene gathers in the middle of the liquid. When the first spiral plate 21 falls from the top of the second spiral plate 31, it drives the internal liquid to shake, so that the pop-up plate 27 is lifted up to drive the graphene to move. The shaking of the liquid makes the spiral rod 34 move, and the internal graphene is stirred when the spiral rod 34 moves. After the stirring is completed, the top of the outer shell 11 is opened to take out the stirred graphene.
