Description

Technical Field

[0001] The invention relates to the technical field of graphite production, and in particular to a production process capable of improving the strength and thermal conductivity of graphite materials. Background Art

[0002] In the graphite production process, the graphite material needs to be impregnated, and the impregnation furnace needs to be pressurized and heated, and then the preheated product is placed in the impregnation tank for impregnation. Most of the current graphite impregnation technologies maintain the uniformity of the impregnation liquid by stirring the impregnation liquid to prevent precipitation or stratification of components, thereby ensuring that the graphite is evenly exposed to the impregnation during the entire impregnation process.

[0003] In this regard, China's patent application number: CN202410676795.1 discloses a graphite electrode impregnation preheating furnace, including a furnace shell, a preheating furnace body is arranged inside the furnace shell, an annular heating plate is fixedly connected to the outer wall of the preheating furnace body, the annular heating plate is in contact with the furnace shell, an outer ring plate is fixedly connected to the top of the outer wall of the furnace shell, a fixed plate is fixedly connected to the bottom of the inner wall of the furnace shell, a rotating mechanism is arranged on the preheating furnace body, and a separation and combination mechanism is arranged on the furnace shell and the fixed plate; the invention can prevent cracks and damage to high-power graphite electrodes, improve the service life of high-power graphite electrodes, and make the impregnation liquid evenly distributed on the surface of the high-power graphite electrode, prevent the impregnation liquid from settling, improve the impregnation uniformity, and avoid damage or breakage of the high-power graphite electrode and damage to the preheating furnace body.

[0004] The device is provided with a detachable square block and a square slot, which can prevent the rotating mechanism from injuring people when placing materials. However, in actual use, the impregnation liquid is stirred by the circular limit frame and surges in the preheating furnace body. After the preheating furnace body rises, the sun gear loses its limit, so the circular limit frame is in an active state. Under the push of the impregnation liquid, the circular limit frame will rotate, and there is still a risk of injury from the rotating mechanism. In addition, the circular limit frame will drive the sun gear and the square block to rotate, causing the square block to shift relative to the square slot. When the preheating furnace body descends, the square block cannot be inserted into the square slot, resulting in the inability to connect the sun gear and the second drive shaft, which affects the user experience of the device.

[0005] Therefore, in order to solve the above problems, a production process is proposed to improve the strength and thermal conductivity of graphite materials. Summary of the invention

[0006] The object of the present invention is to provide a production process that can improve the strength and thermal conductivity of graphite materials, so as to solve the problem that the device in the prior art proposed in the above background technology can avoid the rotating mechanism from injuring people when placing materials by setting a detachable square block and a square groove. However, in actual use, the impregnation liquid will surge in the preheating furnace body due to the stirring of the circular limit frame. After the preheating furnace body is raised, the sun gear loses its limit, so the circular limit frame is in an active state. Under the push of the impregnation liquid, the circular limit frame will rotate, and there is still a risk of injury from the rotating mechanism. In addition, the circular limit frame will drive the sun gear and the square block to rotate, so that the square block is offset relative to the angle of the square groove. When the preheating furnace body descends, the square block cannot be inserted into the square groove, resulting in the inability to connect the sun gear and the second drive shaft, which will affect the user experience of the device.

[0007] To achieve the above object, the present invention provides the following technical solution: A graphite material capable of improving the strength of graphite equipment:

[0008] S1. Use an impregnation solution containing MgCl2, Al(OH)3, H3PO4 and other components. These substances react with graphite at high temperatures to form compounds with higher thermal conductivity, thereby enhancing the thermal conductivity of graphite. Similarly, impregnation solutions containing borax, sodium tripolyphosphate and TiO2 also show good improvement effects. The protective layer formed by these components on the graphite surface not only improves the high-temperature oxidation resistance, but also enhances the thermal conductivity to a certain extent. The processed ordinary graphite products are completely immersed in the impregnation solution in the high-pressure storage tank;

[0009] S2. Release the pressure in the high-pressure storage tank to normal pressure, take out the graphite product and immerse it in water;

[0010] S3. Take out the graphite product, wipe off the surface moisture, immerse it in the impregnation liquid storage tank again, and pressurize the impregnation liquid storage tank;

[0011] S4. Release the pressure of the impregnation liquid storage tank to normal pressure, take out the graphite product and let it stand at room temperature for 4 hours to solidify the impregnation liquid in the graphite product; then wipe the resin precipitated on the surface of the graphite product with an organic reagent;

[0012] S5. The impregnated graphite products were baked at 31-39°C, 71-79°C and 111-119°C for 6h, 6h and 12h, respectively, and the temperature was slowly raised to allow the impregnation liquid to completely solidify and fill the micropores;

[0023] Preferably, the slot is matched with the insertion rod, and the bottom end of the positioning rod passes through the positioning plate.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: the stirring blades of the present invention can remain fixedly connected to the rotating block when the impregnation cylinder descends, so that the stirring blades can be driven to rotate by the rotating block to stir the impregnation liquid inside the cylinder body, and when the impregnation cylinder is raised, the stirring blades can rotate on the rotating block, so that the action of the impregnation liquid on the stirring blades cannot be transmitted to the rotating block, so that the rotating block remains fixed, and the placed net cylinder is fixed in place, which is convenient for taking and placing materials in the placed net cylinder, thereby improving the safety of the use of the device.

[0025] A rotating structure, a stirring structure and a stirring structure are provided. The insertion rod is inserted into the slot. When the motor is started, the connecting shaft and the gear plate can be driven to rotate through the insertion rod. The gear plate is meshed with the gear shaft. The rotation of the gear plate can drive the rotating block to rotate through the gear shaft. The second rubber pad abuts against the bottom surface of the first rubber pad. The stirring blade can be fixed to the top surface of the rotating block through the lifting frame. Therefore, when the rotating block rotates, the impregnation liquid in the impregnation cylinder can be stirred by the stirring blade to avoid precipitation and stratification of the impregnation liquid, thereby ensuring the impregnation effect of the graphite. The rotation of the connecting shaft drives the impregnation cylinder to rotate, which can further stir the impregnation liquid.

[0026] When the electric telescopic rod is started to lift the top cover, the top cover releases the limit of the impregnation cylinder, and the impregnation cylinder is lifted in the cylinder body under the action of the first spring, the gear ring plate drives the impregnation cylinder to lift, and the impregnation cylinder drives the connecting shaft and the connecting rod to move, and the connecting shaft moves upward away from the insertion rod, the insertion rod is separated from the slot, and the connecting arm loses the abutment of the insertion rod, and the connecting arm descends in the slot under the action of the third spring, and the connecting arm drives the connecting rod to move inside the rotating block, and the connecting rod pulls the lifting frame, and the lifting frame squeezes the second spring, and the lifting frame moves in the movable groove, and the lifting frame drives the second rubber pad to descend, and the second rubber pad is away from the first rubber pad, and the friction relationship between the second rubber pad and the first rubber pad can be released, so the stirring blade can rotate on the rotating block, and at this time, when the impregnation liquid flowing in the impregnation cylinder acts on the stirring blade, it can drive the stirring blade to rotate, and at this time, the rotation of the stirring blade will not drive the rotating block to move, so the rotating block can remain fixed, and the placement net cylinder is fixed in place, which is convenient for taking and placing materials in the placement net cylinder, thereby improving the safety of the device;

[0027] At the same time, when the connecting shaft moves upward away from the insertion rod, it can drive the positioning rod to move. The positioning rod rises on the inner side of the positioning plate, so that the angles of the slot and the insertion rod are relatively fixed, thereby preventing the connecting shaft from rotating after the impregnation cylinder is raised, causing the angle of the slot to shift, and making it impossible for the slot and the insertion rod to be aligned when the impregnation cylinder is reset downward, thereby affecting the driving effect of the motor on the impregnation cylinder and the stirring blades.

The stirring blade 33 can remain fixedly connected to the rotating block 31 when the impregnation cylinder 28 descends, so that the stirring blade 33 is driven to rotate by the rotating block 31 to stir the impregnation liquid inside the cylinder body 1, and when the impregnation cylinder 28 rises, the stirring blade 33 can rotate on the rotating block 31, so that the action of the impregnation liquid on the stirring blade 33 cannot be transmitted to the rotating block 31, so that the rotating block 31 remains fixed, and the placement net cylinder 32 is fixed in place, which is convenient for taking and placing materials in the placement net cylinder 32, thereby improving the safety of the device.

The rotation of the insertion rod 24 can drive the stirring structure 3 to operate through the alignment structure 4, and the connecting arm 45 can be raised and lowered in the slot 43 through the third spring 44, and the connecting shaft 41 can drive the positioning rod 46 to move.

[0053] Furthermore, the bottom surface of the rotating pad 14 is fitted with the top surface of the impregnation cylinder 28, the output end of the motor 22 passes through the fixed plate 21, the positioning plate 23 and the insertion rod 24 are both located on the upper side of the fixed plate 21, the insertion rod 24 is inserted into the inside of the slot 43, and the gear ring plate 26 is slidably installed on the inner wall of the cylinder 1. The rotating pad 14 can rotate on the bottom surface of the top cover 13 when the impregnation cylinder 28 rotates, the insertion rod 24 can drive the connecting shaft 41 and the gear plate 42 to rotate through the slot 43, and the gear ring plate 26 can stably rise and fall in the cylinder 1.

[0054] Furthermore, the rotating block 31 is provided with four groups, and four groups of stirring blades 33 are installed on the rotating block 31. The mesh cylinder 32 is placed on the inner side of the four groups of stirring blades 33. The upper end of the stirring blade 33 is rotatably connected to the positioning frame 311. The four groups of gear shafts 36 are all engaged with the gear plate 42. The four groups of stirring blades 33 can stir the impregnation liquid near the rotating block 31 to avoid precipitation and stratification of the impregnation liquid, thereby ensuring the impregnation effect of the graphite. The rotation of the gear plate 42 can drive the rotation of the four groups of gear shafts 36.

[0055] Furthermore, the bottom end of the lifting frame 37 is movably mounted on the inner side of the rotating block 31, the second rubber pad 38 cooperates with the first rubber pad 35, the bottom end of the connecting rod 39 is fixedly connected to the connecting arm 45, one end of the second spring 310 is fixedly connected to the inner wall of the rotating block 31, and when the second rubber pad 38 is in contact with the first rubber pad 35, the stirring blade 33 can be fixed on the rotating block 31, and when the rotating block 31 rotates, the immersion liquid can be stirred by the stirring blade 33, and when the second rubber pad 38 is separated from the first rubber pad 35, the movement of the immersion liquid can push the stirring blade 33 to rotate, so that the rotating block 31 is fixed, and the movement of the connecting arm 45 can drive the lifting frame 37 to move through the connecting rod 39, and the second spring 310 provides power for the movement of the lifting frame 37 in the rotating block 31.

[0056] Furthermore, the connecting arm 45 is in a "cross" shape, and the connecting arm 45 passes through the side wall of the connecting shaft 41. The connecting arm 45 is slidably installed on the inner side of the slot 43. The movement of the connecting arm 45 on the inner side of the slot 43 can drive the movement of the four groups of connecting rods 39.

[0057] Furthermore, the slot 43 is adapted to the insertion rod 24, and the bottom end of the positioning rod 46 passes through the positioning plate 23. The slot 43 is aligned with the insertion rod 24 at an angle. When the impregnation cylinder 28 descends, the insertion rod 24 can be straightly inserted into the slot 43. The positioning rod 46 cooperates with the positioning plate 23 to limit the angle between the slot 43 and the insertion rod 24, thereby preventing the impregnation cylinder 28 from driving the connecting shaft 41 to rotate, causing the slot 43 and the insertion rod 24 to deviate, resulting in the inability to insert the insertion rod 24 into the slot 43.

[0058] Working principle: When in use, start the electric telescopic rod 11 to lift the top cover 13, start the motor 12 to drive the top cover 13 to rotate, move the top cover 13 to the outside of the cylinder 1, so as to place the material inside the net cylinder 32, and then control the electric telescopic rod 11 and the motor 12 to cover the top surface of the cylinder 1;

[0059] The plug rod 24 is inserted into the slot 43, and the motor 22 is started. The plug rod 24 can drive the connecting shaft 41 and the gear plate 42 to rotate. The gear plate 42 is meshed with the gear shaft 36. The rotation of the gear plate 42 can drive the rotating block 31 to rotate through the gear shaft 36. The second rubber pad 38 abuts against the bottom surface of the first rubber pad 35. The stirring blade 33 can be fixed to the top surface of the rotating block 31 through the lifting frame 37. Therefore, when the rotating block 31 rotates, the stirring blade 33 can stir the impregnation liquid in the impregnation cylinder 28 to avoid precipitation and stratification of the impregnation liquid, thereby ensuring the impregnation effect of the graphite. The rotation of the connecting shaft 41 drives the impregnation cylinder 28 to rotate, which can further stir the impregnation liquid.

[0060] The electric telescopic rod 11 is started to lift the top cover 13, and the top cover 13 releases the limit on the dipping cylinder 28. The dipping cylinder 28 rises in the cylinder body 1 under the action of the first spring 25, and the gear ring plate 26 drives the dipping cylinder 28 to rise. The dipping cylinder 28 drives the connecting shaft 41 and the connecting rod 39 to move, and the connecting shaft 41 moves upward away from the insertion rod 24, and the insertion rod 24 is separated from the slot 43, and the connecting arm 45 loses the abutment of the insertion rod 24. The connecting arm 45 descends in the slot 43 under the action of the third spring 44, and the connecting arm 45 drives the connecting rod 39 to move inside the rotating block 31, and the connecting rod 39 pulls the lifting frame 37, and the lifting frame 37 squeezes the second spring 31. 0, the lifting frame 37 moves in the movable groove 34, and the lifting frame 37 drives the second rubber pad 38 to descend, and the second rubber pad 38 moves away from the first rubber pad 35, so that the friction relationship between the second rubber pad 38 and the first rubber pad 35 can be released, so the stirring blade 33 can rotate on the rotating block 31. At this time, when the impregnation liquid flowing in the impregnation cylinder 28 acts on the stirring blade 33, it can drive the stirring blade 33 to rotate. At this time, the rotation of the stirring blade 33 will not drive the rotating block 31 to move, so the rotating block 31 can remain fixed, and the placement net cylinder 32 is fixed in place, which is convenient for taking and placing materials in the placement net cylinder 32, thereby improving the safety of the device;

[0061] At the same time, when the connecting shaft 41 moves upward away from the insertion rod 24, it can drive the positioning rod 46 to move. The positioning rod 46 rises on the inner side of the positioning plate 23, so that the angles of the slot 43 and the insertion rod 24 are relatively fixed, thereby preventing the connecting shaft 41 from rotating after the immersion cylinder 28 is raised, causing the angle of the slot 43 to shift, and making it impossible for the slot 43 and the insertion rod 24 to be aligned when the immersion cylinder 28 is reset downward, thereby affecting the driving effect of the motor 22 on the immersion cylinder 28 and the stirring blade 33.

Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above.
