[0031] The following specifically describes the specific settings and functions of its heat preservation device 5.

[0032] As Figures 2-5As shown in the figure, the heat preservation device 5 includes two first arc-shaped rods 501. Both of the two first arc-shaped rods 501 are slidably connected to the furnace body 3. A heat preservation board 502 is fixedly connected to the surface of the first arc-shaped rod 501. A second arc-shaped rod 503 is fixedly connected to the surface of the heat preservation board 502. The second arc-shaped rod 503 is slidably connected to the furnace body 3. A fixing plate 504 is fixedly connected to the surface of the first arc-shaped rod 501. A lead screw 505 is slidably connected to the surface of the fixing plate 504. A nut 506 is threadedly connected to the arc surface of the lead screw 505. One end of the lead screw 505 is fixedly connected to an adjusting rod 507. Two grooves 508 are formed on the surface of the adjusting rod 507. A rotating shaft 509 is rotatably connected to the surface of both of the two grooves 508. A baffle 510 is fixedly connected to the arc surface of the rotating shaft 509. The baffle 510 is adapted to the size of the groove 508. A sliding ring 511 is fixedly connected to the surface of the baffle 510. A sliding rod 512 is slidably connected to the surface of the sliding ring 511. The sliding rod 512 is fixedly connected to the inner wall of the adjusting rod 507. A spring 513 is sleeved on the arc surface of the sliding rod 512. Both ends of the spring 513 are fixedly connected to the adjusting rod 507 and the sliding ring 511 respectively. An adjusting belt 515 is slidably connected to the arc surface of the second arc-shaped rod 503. A screw 516 is threadedly connected to the surface of the adjusting belt 515. A ball 517 is rotatably connected to the surface of the adjusting belt 515. The ball 517 is slidably connected to the second arc-shaped rod 503. The adjusting belt 515 drives the ball 517 to move along the surface of the second arc-shaped rod 503. At this time, the ball 517 can reduce the friction between the adjusting belt 515 and the second arc-shaped rod 503. One end of the screw 516 is fixedly connected to an elastic cord 518. The other end of the elastic cord 518 is fixedly connected to the adjusting belt 515. The screw 516 drives one end of the elastic cord 518 to move. At this time, the elastic cord 518 can prevent the screw 516 from being lost. A sealing gasket 519 is fixedly connected to the surface of the heat preservation board 502. The sealing gasket 519 is a rubber gasket. The heat preservation board 502 drives the sealing gasket 519 to move. At this time, the rubber sealing gasket 519 can increase the sealing performance between the two heat preservation boards 502. One end of the adjusting rod 507 is fixedly connected to a tapered tip 520. The vertical cross-section of the tapered tip 520 is trapezoidal. The adjusting rod 507 drives the tapered tip 520 to pass through the fixing plate 504. At this time, the tapered tip 520 with a trapezoidal vertical cross-section can facilitate the adjusting rod 507 to pass through the fixing plate 504. One end of the baffle 510 is fixedly connected to an auxiliary block 521. The auxiliary block 521 has a cuboid structure. The baffle 510 drives the auxiliary block 521 to fit with the fixing plate 504. At this time, the cuboid-shaped auxiliary block 521 can increase the contact area between the baffle 510 and the fixing plate 504. A plurality of rotating rods 522 are fixedly connected to the surface of the nut 506. The plurality of rotating rods 522 are evenly distributed on the arc surface of the nut 506. Rotating the rotating rods 522, and at the same time, the rotating rods 522 drive the nut 506 to rotate. At this time, the rotating rods 522 can facilitate the rotation of the nut 506.

[0033] The overall working principle is as follows. When insulating the furnace body 3, first, put two first arc-shaped rods 501 and two second arc-shaped rods 503 on the surface of the furnace body 3. Then, the first arc-shaped rod 501 and the second arc-shaped rod 503 will drive the heat-insulating plate 502 to fit against the furnace body 3. Next, pass the adjusting rod 507 at one end of the screw rod 505 through the two fixing plates 504. At this time, the fixing plates 504 will close the two baffle plates 510 towards the direction close to the groove 508. Then, the adjusting rod 507 will drive the tapered cone 520 through the fixing plate 504. At this time, the tapered cone 520 with a trapezoidal vertical section can facilitate the adjusting rod 507 to pass through the fixing plate 504. When the adjusting rod 507 passes through the fixing plate 504, then rotate the rotating rod 522, and at the same time, the rotating rod 522 will drive the nut sleeve 506 to rotate. At this time, the rotating rod 522 can facilitate the rotation of the nut sleeve 506. Then, the nut sleeve 506 will move along the surface of the screw rod 505 towards the direction close to the fixing plate 504 by means of its own thread. Next, the cooperation between the nut sleeve 506 and the fixing plate 504 will drive the screw rod 505 to move away from the fixing plate 504, and at the same time, the screw rod 505 will drive the adjusting rod 507 to move towards the direction close to the fixing plate 504. Then, release the two baffle plates 510 and continue to rotate the nut sleeve 506. Then, the adjusting rod 507 will drive one end of the sliding rod 512 to move. Then, the sliding rod 512 will compress the spring 513, and at the same time, the spring 513 will compress the sliding ring 511. Then, the sliding ring 511 will drive the baffle plate 510 to rotate. Then, the baffle plate 510 will drive the rotating shaft 509 to rotate along the surface of the groove 508. At this time, the two baffle plates 510 will be opened and fit against the fixing plate 504. At this time, the baffle plate 510 will drive the auxiliary block 521 to fit against the fixing plate 504. At this time, the auxiliary block 521 with a cuboid structure can increase the contact area between the baffle plate 510 and the fixing plate 504. Then, continue to rotate the nut sleeve 506 to make the nut sleeve 506 tightly fit against the fixing plate 504 by means of its own thread, fixing the position of the two first arc-shaped rods 501. At the same time, the first arc-shaped rod 501 will drive the two heat-insulating plates 502 to move towards each other. Then, the heat-insulating plate 502 will drive the sealing gasket 519 to move. At this time, the sealing gasket 519 made of rubber can increase the sealing performance between the two heat-insulating plates 502. Then, put the adjusting belt 515 on the surface of the second arc-shaped rod 503, and then rotate the screw rod 516. At the same time, the screw rod 516 will drive one end of the elastic rope 518 to move. At this time, the elastic rope 518 can prevent the screw rod 516 from being lost. At this time, the screw rod 516 will move the two ends of the adjusting belt 515 towards each other by means of its own thread. Then, the adjusting belt 515 will drive the ball 517 to move along the surface of the second arc-shaped rod 503. At this time, the ball 517 can reduce the friction between the adjusting belt 515 and the second arc-shaped rod 503. Then, closely fit the two ends of the adjusting belt 515 to limit the two second arc-shaped rods 503. By setting the heat-insulating device 5,By means of the cooperation among the first arc-shaped rod 501, the heat preservation plate 502, the second arc-shaped rod 503, the fixing plate 504, the lead screw 505, the nut sleeve 506, the adjusting rod 507, the groove 508, the rotating shaft 509, the baffle 510, the sliding ring 511, the sliding rod 512, the spring 513, the adjusting belt 515 and the screw 516, the heat preservation plate 502 can be closely attached to the furnace body 3, avoiding the influence of the external environment on the temperature inside the furnace body 3 during the working process of the furnace body 3, resulting in rapid heat loss of the temperature inside the furnace body 3, so that the temperature inside the furnace body 3 needs to be continuously heated to continue working, leading to waste of heat energy, thereby reducing the speed of oxalic acid catalytic degreasing, reducing the speed of heat loss in the oxalic acid catalytic degreasing furnace, and improving the efficiency of oxalic acid catalytic degreasing.
