Description

Technical Field

[0001] The invention relates to the technical field of graphite ceramic composite material production, in particular to graphite ceramic composite material production equipment and a process method. Background Art

[0002] Graphite-ceramic composites are a new type of material created by combining graphite and ceramic materials through a specific process. They combine the excellent properties of graphite and ceramic, such as graphite's excellent electrical conductivity, thermal conductivity, and lubricity, with ceramic's high hardness, wear resistance, high-temperature resistance, and corrosion resistance. Through this process, graphite-ceramic composites retain some of the properties of graphite while enhancing its strength, hardness, and high-temperature resistance. They are widely used in aerospace, machinery manufacturing, electronics, and chemical industries. To improve efficiency and ensure product quality, graphite-ceramic composite production equipment is often used in the production of graphite-ceramic composites. Graphite-ceramic composite production equipment refers to specialized equipment or systems used to produce graphite-ceramic composites.

[0031] The surface of the bottom plate 1 is provided with a mixing mechanism, which includes a first fixed block 2, which is fixedly connected to the upper surface of the bottom plate 1, and a first rotating rod 21 is movably connected to the inner side of the first fixed block 2, and a turntable 22 is fixedly connected to the surface of the first rotating rod 21.

A movable block 25 is movably connected to the surface of the connecting block 24. The bottom end of the fixed box 16 is fixedly connected to a first connecting plate 26, and a through groove 27 is provided on the inner side of the first connecting plate 26. The first rotating rod 21 is driven to rotate by the second motor 23, so that the turntable 22 rotates accordingly, which can drive the connecting block 24 and the movable block 25 to move, and then the first connecting plate 26 can drive the fixed box 16 to move vertically under the action of the movable block 25, so that the stirring shaft 14 and the stirring rod 15 can stir the graphite and ceramic powder at different positions, so as to expand the stirring range, thereby better mixing the graphite and ceramic powder, which is beneficial to improving the quality of subsequent production of graphite ceramic composite materials.

[0032] Furthermore, the mixing mechanism also includes a fixed plate 28, which is fixedly connected to the upper surface of the base plate 1. A limiting groove 29 is opened on the inner side of the fixed plate 28, and the first connecting plate 26 moves on the inner side of the limiting groove 29. The opening of the limiting groove 29 facilitates the movement of the first connecting plate 26 on the inner side of the limiting groove 29, which can avoid the first connecting plate 26 from being offset and facilitates the first connecting plate 26 to move vertically stably.

[0033] Furthermore, the first rotating rod 21 and the output end of the second motor 23 are fixedly connected, and the movable block 25 is movably connected to the connecting block 24 through the rotating shaft.

Through the setting of the movable block 25, when the turntable 22 rotates, the position of the connecting block 24 changes, and the movable block 25 moves in the through groove 27, which can drive the first connecting plate 26 to move vertically, thereby changing the range and area of ​​stirring of graphite and ceramic powder by the stirring shaft 14 and the stirring rod 15.

[0034] Furthermore, a separation mechanism is provided on the inner side of the bottom plate 1, and the separation mechanism includes a first conical tooth 3, the first conical tooth 3 is fixedly connected to the surface of the first rotating rod 21, the surface of the mixing box 11 is fixedly connected to a second fixed block 31, the inner side of the second fixed block 31 is movably connected to a second rotating rod 32, the surface of the second rotating rod 32 is fixedly connected to a cam 33, the bottom end of the second rotating rod 32 is fixedly connected to a second conical tooth 34, the inner wall of the mixing box 11 is fixedly connected to a fixing rod 35, and the surface of the fixing rod 35 is movably connected to the second connecting rod. Plate 36, the top of the second connecting plate 36 is fixedly connected with a sieve plate 37, and the rotation of the second rotating rod 32 can drive the cam 33 to rotate accordingly, so that the cam 33 can squeeze the third connecting plate 39, so that the movable rod 38 can drive the second connecting plate 36 and the sieve plate 37 to move, and the elastic properties of the spring 310 facilitate the reciprocating motion of the sieve plate 37, thereby improving the efficiency and effect of screening the graphite and ceramic powders, so that the stirring rod 15 can better stir the graphite and ceramic powders.

[0035] Furthermore, a movable rod 38 is fixedly connected to the surface of the second connecting plate 36, a third connecting plate 39 is fixedly connected to the surface of the movable rod 38, and a spring 310 is fixedly connected to the surface of the third connecting plate 39. By the movable rod 38 in the mixing box 11 and the setting of the spring 310, the sieve plate 37 can be reset under the action of the spring 310 after it moves under the action of the cam 33, so that the sieve plate 37 can reciprocate, which is convenient for better screening of graphite and ceramic powders.

[0036] Furthermore, the fixed rods 35 are in two groups and fixedly connected to the mixing box 11, the sieve plate 37 is movable on the inner side of the mixing box 11, and the movable rods 38 are in two groups and fixedly connected to the second connecting plate 36. Through the setting of the sieve plate 37, the graphite and ceramic powders can be screened, and then the graphite and ceramic powders can be removed for impurities, which can ensure the quality of the production of graphite ceramic composite materials.

[0037] Furthermore, the movable rod 38 moves on the inner side of the mixing box 11, one end of the spring 310 is fixedly connected to the mixing box 11, and the other end of the spring 310 is fixedly connected to the third connecting plate 39. Through the setting of the spring 310, the third connecting plate 39 can be reset, and then the sieve plate 37 can be reset accordingly.

[0038] Furthermore, a feeding mechanism is provided on the inner side of the feed port 12, and the feeding mechanism includes a third conical tooth 4, which is fixedly connected to the top end of the second rotating rod 32, and a third rotating rod 41 is movably connected to the inner side of the feed port 12, and a fourth connecting plate 42 is fixedly connected to the surface of the third rotating rod 41, and a fourth conical tooth 43 is fixedly connected to the surface of the third rotating rod 41. Through the cooperation of the third conical tooth 4 and the fourth conical tooth 43, when the second rotating rod 32 rotates, the third conical tooth 4 rotates to transmit the fourth conical tooth 43, thereby facilitating the third rotating rod 41 to drive the fourth connecting plate 42 to rotate accordingly.

[0039] Furthermore, the fourth connecting plate 42 is fixedly connected to the third rotating rod 41 in four groups, and the fourth connecting plate 42 moves on the inner side of the feed port 12. Through the setting of the fourth connecting plate 42, when the third rotating rod 41 drives the fourth connecting plate 42 to rotate, the fourth connecting plate 42 can break up the agglomerated graphite and ceramic powder, so as to facilitate better screening of the graphite and ceramic powder through the sieve plate 37.

[0040] Working principle: When in use, the second motor 23 is electrically connected to an external power source, and the staff starts the second motor 23 by pressing the switch. The operation of the second motor 23 drives the first rotating rod 21 to rotate, and the turntable 22 will rotate accordingly under the action of the first rotating rod 21. During the rotation of the turntable 22, the connecting block 24 drives the movable block 25 to move accordingly, and realizes the movable block 25 to move in the through groove 27. The first connecting plate 26 is limited by the fixed plate 28 and the limiting groove 29, and will move vertically in the limiting groove 29 under the action of the movable block 25, so that the stirring shaft 14 and the stirring rod 15 can move vertically at the same time during the rotation process, thereby expanding the range and area of ​​stirring;

[0041] The setting of the sieve plate 37 realizes the screening of graphite and ceramic powder, so that the screened graphite and ceramic powder can fall through the holes of the sieve plate 37 and enter the mixing box 11 to be mixed, while the impurity particles are intercepted and roll down through the surface of the sieve plate 37 to be discharged. When the first rotating rod 21 rotates, the first conical teeth 3 rotate, which can drive the second conical teeth 34, and then the second conical teeth 34 rotate and drive the second rotating rod 32 to rotate accordingly. The cam 33 will rotate under the action of the second rotating rod 32, and the rotation of the cam 33 will drive the third connecting rod 32 to rotate. The plate 39 causes extrusion, so that the movable rod 38 moves under the action of the third connecting plate 39, and then the second connecting plate 36 moves on the surface of the fixed rod 35, and the screen plate 37 moves. At this time, the spring 310 is in a contracted state. When the cam 33 cancels the extrusion of the third connecting plate 39 during the rotation process, the third connecting plate 39 is reset under the rebound action of the spring 310, and then the screen plate 37 is reset accordingly. Therefore, the cooperation between the cam 33 and the spring 310 allows the screen plate 37 to reciprocate, thereby improving the screening quality and efficiency of the screen plate 37;

[0042] When the second rotating rod 32 rotates, the third conical tooth 4 rotates accordingly, and the rotation of the third conical tooth 4 transmits the transmission to the fourth conical tooth 43. Then the third rotating rod 41 rotates under the action of the fourth conical tooth 43 and drives the fourth connecting plate 42 to rotate accordingly. The rotation of the fourth connecting plate 42 can break up the graphite and ceramic powder in the feed port 12, thereby avoiding the agglomeration of the graphite and ceramic powder, so that the graphite and ceramic powder can be better screened by the sieve plate 37.
