[0027] Specifically, the cover opening mechanism 4 further comprises a positioning assembly 49, the positioning assembly 49 comprising a U-shaped baffle 491, a wear-resistant pad 492, a limiting rod 493, a second spring 494 and a pressing block 495, the U-shaped baffle 491 being fixedly arranged on the inner side of the mounting branch plate 41, the wear-resistant pad 492 being fixedly arranged on the inner side of the U-shaped baffle 491, one end of the limiting rod 493 being rotatably connected to one side of the U-shaped baffle 491, the limiting rod 493 being connected to the U-shaped baffle 491 through the second spring 494, and the pressing block 495 being fixedly arranged on the bottom of the fixed block 31 and abutting against the limiting rod 493. In this embodiment, since the output shaft of the motor can rotate freely when not working, the positioning assembly 49 can fix the electric push rod 46 when it is rotated to the vertical state, so as to avoid the electric push rod 46 from rotating back after the first motor 42 stops rotating, which can cause the furnace cover 2 to slide down, thereby improving the safety performance of the equipment. The opening of the U-shaped baffle 491 faces the side of the electric push rod 46, the wear-resistant pad 492 is made of rubber material, which can avoid wear between the U-shaped baffle 491 and the electric push rod 46, and is helpful to prolong the service life of the equipment.

In the embodiment, the water storage tank 51 is filled with cooling water, the annular spraying pipe 54 is sleeved on the furnace body 1, and the annular spraying pipe 54 does not contact the side wall of the furnace body 1. The water outlet pump 52 is used for pumping the cooling water into the annular spraying pipe 54. The spray head 55 is a multi-purpose spray head which can sprinkle water and spray mist. The spray head 55 can spray water mist to the outer wall of the furnace body 1, and the furnace body 1 is rapidly cooled by using the principle of water mist evaporation and heat absorption, so as to reduce the discharging waiting time. The lifting assembly 56 is used for driving the annular spraying pipe 54 to move up and down, and when the graphite in the furnace body 1 is completely taken out, the annular spraying pipe 54 can be driven to move to the topmost position, so that the spray head 55 on the annular spraying pipe 54 is above the convex edge and is aligned with the inner wall of the furnace body 1, and then water is sprayed into the furnace body 1 to realize the flushing or cooling of the inner wall of the furnace body 1. The infrared temperature sensor 57 can detect the temperature of the outer wall or the inner wall of the furnace body 1. A controller is further fixed on one side of the water storage tank 51, and the controller can receive and identify the temperature information collected by the infrared temperature sensor 57, and then control the cooling mechanism 5 to work when the temperature is high, so as to cool the furnace body 1.

[0030] Specifically, the lifting assembly 56 comprises a lifting motor 561, a threaded shaft 562 and a lifting seat 563.

[0032] Specifically, the furnace cover 2 side is also fixed with a pressure relief valve 23. In this embodiment, because the graphitization furnace is in a vacuum state during use, the pressure in the furnace is less than the atmospheric pressure, so that the furnace cover 2 is adsorbed on the furnace body 1, causing the cover to be difficult to open. By setting the pressure relief valve 23, the inside of the furnace body 1 can be depressurized when opening the cover, reducing the difficulty of opening the cover.

[0033] Working principle: when the furnace cover 2 needs to be opened, first open the pressure relief valve 23 to make the pressure inside and outside the furnace body 1 consistent, then start the first motor 42, the first motor 42 drives the first rotating gear 43 to rotate, and then drives the electric push rod 46 to rotate from the horizontal state to the vertical state, at this time the electric push rod 46 is clamped into the U-shaped baffle 491, and the clamping rod 47 is clamped into the bottom of the umbrella-shaped handle 21 to clamp and fix the handle 21, and the electric push rod 46 rotates to the vertical state, which will push the sliding rod 37 to slide, the sliding rod 37 pushes the transmission rod 36 to swing through the arc-shaped rod 38, the transmission rod 36 swings to drive the wedge-shaped clamping block 33 into the cavity 32, so that the furnace cover 2 is separated from the furnace body 1, then start the electric push rod 46, the electric push rod 46 is elongated to drive the clamping rod 47 to rise, and then the furnace cover 2 is separated from the furnace body 1, at this time the extrusion block 495 is separated from the limiting rod 493, so that the limiting rod 493 rotates under the action of the second spring 494, thereby limiting the electric push rod 46 in the U-shaped baffle 491 to be fixed, so as to prevent the first motor 42 from rotating after stopping, and the electric push rod 46 loses the force and rotates, which helps to improve the safety performance of the equipment;

[0034] When the furnace body 1 needs to be cooled, the temperature of the outer wall of the furnace body 1 is detected by the infrared temperature sensor 57, and the lifting motor 561 drives the threaded shaft 562 to rotate, thereby driving the annular spray pipe 54 to move up and down reciprocally, at this time the water pump 52 pumps the cooling water in the water storage tank 51 into the annular spray pipe 54, and then the spray head 55 sprays onto the outer wall of the furnace body 1 to cool the furnace body 1; when the inner wall of the furnace body 1 needs to be cooled, only need to move the annular spray pipe 54 to the top of the side wall of the furnace body 1, and then make the spray head 55 pass over the convex edge and align with the inner wall of the furnace body 1, so as to flush and cool the inner wall of the furnace body 1.
