Description

Technical Field

[0001] The utility model relates to the technical field of graphitization equipment, in particular to a box-type graphitization furnace with rapid sealing of the furnace door. Background Art

[0002] The experimental graphitization furnace is a device that converts carbon materials into graphite materials, commonly used in scientific research and small-scale experiments. It uses electric heating to rearrange carbon atoms under high temperature and inert gas protection to form a graphite crystal structure, improving the electrical conductivity, thermal conductivity and other properties of the material. This device generally consists of a furnace body, heating elements, a temperature control system and a gas protection system;

[0003] During the use of some existing graphitization furnaces, the sealing of the furnace door is not convenient enough, and the crucible cannot be quickly sent into the furnace chamber and effectively sealed. This not only affects the experimental efficiency, but also may cause gas leakage in the furnace, interfering with the accuracy of the experiment. Therefore, after the furnace door is closed by a pneumatic device, several bolts need to be manually tightened on the furnace door to ensure the stability of the furnace door closing on the furnace opening, but this undoubtedly increases the complexity of the operation. In addition, if the starting device suddenly fails, the furnace door may fall, seriously threatening the safety of experimental personnel and the integrity of the equipment.

The second chute 27 is slidably mounted on the corresponding guide rail 18. Third chutes 28 are provided on both sides of the fixed seat 15. A baffle 29 is fixedly mounted on the front side of the fixed seat 15. The cooperation of the collar 13, the side rod 14 and the fixed seat 15 can synchronously realize the lifting movement of the first wedge 16 when the piston rod 5 lifts and lowers the furnace door 6.

[0028] It should be noted that the present utility model is a box-type graphitization furnace with rapid sealing of the furnace door. During operation, the operator first sets the working parameters of the heating module, such as temperature, heating time, etc., through the controller 2, prepares the crucible containing the experimental materials and places it on the crucible base 7. Then, the equipment is started, and the air pump in the chassis 1 starts to work, delivering gas to the cylinder 4. The piston rod 5 in the cylinder 4 extends under the action of gas pressure. At this time, the collar 13 moves synchronously with the piston rod 5. Since the collar 13 is slidably connected to the guide rail 18 through the second chute 27, under the guiding action of the guide rail 18, the piston rod 5 drives the furnace door 6 to move smoothly towards the furnace chamber 17, thereby driving the fixed seat 15 and the first wedge block 16 installed on the fixed seat 15 to rise. As the furnace door 6 approaches the furnace chamber 17, the first wedge block 16 rises and presses the second wedge block 23, causing the anti-falling plate 10 to move towards the furnace door 6 against the elastic force of the first compression spring 24, and making the two anti-falling plates 10 gradually insert into one side of the bottom of the furnace door 6 through the rubber pads 26 in the supporting grooves 25 on one side respectively. And the T-shaped inserts 37 at one ends of the two pull rods 12 are respectively inserted into the corresponding T-shaped grooves 33. At this time, the two anti-falling plates 10 limit the downward movement of the furnace door 6. When the cylinder 4 fails, since the two anti-falling plates 10 limit the downward movement of the furnace door 6, and then limit the downward movement of the piston rod 5 through the furnace door 6, thus playing an anti-falling role. Subsequently, the protective door 3 can be closed, and the controller 2 is used to start the furnace chamber 17 to heat-treat the materials in the crucible;

[0029] After the material sintering is completed, the protective door 3 can be opened, and the connecting rod 38 is manually pulled towards the operator. Then, the connecting rod 38 synchronously pulls the two pull rods 12 to move, so that the T-shaped inserts 37 at one ends of the two pull rods 12 respectively pull the corresponding fixing blocks 32 towards the operator, which can make the fixing blocks 32 cooperate with the connecting rod 31 to pull the first wedge block 16, and make the first wedge block 16 compress the second compression spring 34 towards the baffle 29. Thus, the two first wedge blocks 16 slide horizontally on the corresponding fixed seats 15 respectively and disengage from the corresponding second wedge blocks 23, so that the first compression spring 24 stretches and rebounds to push the first slider 22 back to its original position, which can make the first slider 22 pull the anti-falling plate 10 into the receiving groove 19, so that the supporting groove 25 part on one side of the anti-falling plate 10 disengages from the bottom of the furnace door 6. At this time, the connecting rod 38 can be released, and the controller 2 is used to control the piston rod 5 to descend, so that the piston rod 5 drives the furnace door 6 to descend and cooperate with the crucible base 7 to move the crucible out of the furnace chamber 17.
