Technical Field

[0001] This utility model relates to the field of ceramic furnace insulation technology, and in particular to a heat insulation device for the furnace body of a ceramic furnace. Background Technology

[0002] Porcelain veneers are a dental technique that combines the high strength of metal, the aesthetics of porcelain, the lifelike appearance of teeth, and wear resistance. They can restore missing front and back teeth, achieving the ideal function and shape, improving pronunciation, and harmonizing with adjacent teeth, lips, occlusion, and facial appearance, giving the individual and others a complete and harmonious aesthetic. The production of this product requires the use of a porcelain furnace for firing and shaping.

[0003] Chinese patent document CN219913959U discloses a heat insulation device for a ceramic kiln body, including a cabinet. A first electric heating device is installed on the inner wall of the cabinet, and second electric heating devices are installed on both the left and right sides of the inner wall. A heat-conducting plate is installed on the outer wall of the second electric heating devices. A sliding groove is formed inside the heat-conducting plate, and a baking tray is slidably connected to the inner wall of the groove. In this invention, heat energy is first generated by the first electric heating device on the inner wall of the cabinet and the second electric heating devices on the left and right sides of the inner wall, thereby raising the internal temperature of the cabinet. Then, the heat is transferred to the baking tray through the heat-conducting plate on the outer wall of the first and second electric heating devices. Finally, the rotation of the heat-conducting fan maintains a constant internal temperature.

[0004] The existing technology has the following problems:

[0005] The cabinet and door of this ceramic kiln are directly connected by a rotating joint, and the sealing between them is achieved solely by a rubber ring. Since the rotating position is fixed, if the side of the cabinet door and cabinet body away from the rotating position is fixed more tightly, it may cause the rubber ring near the rotating position to be less tight.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5As shown, a heat insulation device for a ceramic furnace body includes a furnace body 1, a sealing mechanism 2 fixedly connected to the front and rear sides of the furnace body 1, four rectangular support feet 3 fixedly connected to the lower side of the furnace body 1 near the four corners, and four rectangular placement grooves 4 opened on the front and rear sides of the inner side of the furnace body 1, with two placement mechanisms 5 movably sleeved on the inner side of the placement grooves 4.

[0027] The sealing mechanism 2 includes an insulation sealing plate 21. Two connecting platforms 22 are fixedly connected to the front and rear sides of the insulation sealing plate 21. Two sliding tables 23 are slidably connected to the front and rear sides of the furnace body 1 near the left side. The rear side of the connecting platform 22 on the rear side is rotatably connected to the rear side of the sliding table 23 on the rear side. Several electric telescopic rods 24 distributed vertically are fixedly connected to the right side of each of the two sliding tables 23. The outer side of the electric telescopic rods 24 is fixedly connected to the front and rear sides of the furnace body 1 near the right side. The outer side of the connecting platform 22 and the sliding table 23 on the front side is movably fitted with a retaining sleeve 25.

[0028] It should be noted that the insulation structure on the furnace body 1 is consistent with the structure of the component with the same function in the reference case. The right side boss of the insulation sealing plate 21 is movably fitted into the inner side of the furnace body 1. The electric telescopic rod 24 drives the slide 23 to move left and right. The clamp 25 is used to fix the front connecting platform 22 and the slide 23 together. It can be removed from the connecting platform 22 by using a pin. When the electric telescopic rod 24 drives the insulation sealing plate 21 to move towards the furnace body 1, the insulation sealing plate 21 is subjected to balanced force at all points in front and behind, avoiding the problem of seal failure caused by unstable force on one side.

[0029] like Figure 3 As shown, the right side of the two connecting platforms 22 and the left side of the two sliding platforms 23 are all fixedly connected with the first rubber pad.

[0030] It should be noted that the first rubber pad is used to fill the gap between the connecting platform 22 and the slide 23 to prevent the insulation sealing plate 21 from shaking on the slide 23.

[0031] like Figure 3 As shown, a reflective film is provided on the right side of the right boss of the thermal insulation sealing plate 21.

[0032] It should be noted that the reflective film is used to reflect the heat projected onto the insulation sealing plate 21 back to the inside of the furnace body 1, thereby improving the heat preservation capacity of the insulation sealing plate 21.

[0033] like Figure 2 , Figure 4 and Figure 5As shown, the placement mechanism 5 includes a tray 51. The outer side of the tray 51 is movably sleeved on the inner side of the placement groove 4 near the front and rear sides. The front and rear sides of the tray 51 are movably sleeved with sliding rods 52. The upper side of each sliding rod 52 is rotatably connected to several horizontally distributed top support components 53. The top support component 53 includes a first rotating rod 531. The side of the first rotating rod 531 away from the furnace body 1 is fixedly connected to a top block 532. The lower side of the top block 532 is rotatably connected to the upper side of the tray 51 near the front and rear sides. The upper side of the top block 532 away from the first rotating rod 531 is rotatably connected to a second rotating rod 533. The lower side of the second rotating rod 533 is rotatably connected to the upper side of the sliding rod 52.

[0034] It should be noted that the outer side of the first rotating rod 531 is movably sleeved on the inner side of the mounting groove 4. Pushing the slide rod 52 to the right causes the slide rod 52 to drive the second rotating rod 533 to move to the right, thereby causing the first rotating rod 531 to move upward, so that the upper side of the first rotating rod 531 abuts against the upper inner side of the mounting groove 4.

[0035] like Figure 4 , Figure 5 As shown, push blocks 54 are fixedly connected to the left side of both slide rods 52, and second rubber pads are fixedly connected to the left side of both push blocks 54.

[0036] It should be noted that the second rubber pad is used to prevent rigid contact between the push block 54 and the thermal insulation sealing plate 21, which could lead to excessive compression and deformation between the components. The second rubber pad can be made of high-temperature resistant rubber.

[0037] like Figure 4 As shown, the top support component 53 is made of ceramic material.

[0038] It should be noted that all components on the top support assembly 53 are made of ceramic material to reduce the impact of temperature and avoid excessive compression between components due to thermal expansion, which could cause deformation.

[0039] like Figure 2 As shown, the bottom of the inner side of the four placement slots 4 that are far apart from each other is inclined towards the side closer to the tray 51.

[0040] It should be noted that the shape of the placement groove 4 causes the tray 51 to move down relative to the first rotating rod 531 and contact the bottom of the inner side of the placement groove 4 after the first rotating rod 531 is pressed against the upper inner side of the placement groove 4, thus preventing the tray 51 from moving back and forth.

[0041] The working principle of this utility model is as follows: First, the right side boss of the insulation sealing plate 21 is movably sleeved on the inner side of the furnace body 1. The electric telescopic rod 24 drives the slide 23 to move left and right. The clamp 25 is used to fix the front connecting platform 22 and the slide 23 together. It can be removed from the connecting platform 22 by using a pin. When the electric telescopic rod 24 drives the insulation sealing plate 21 to move towards the furnace body 1, the insulation sealing plate 21 is subjected to balanced force at all points, avoiding the problem of seal failure caused by unstable force on one side. The first rubber gasket is used for... To fill the gap between the connecting platform 22 and the sliding platform 23 and prevent the insulation sealing plate 21 from wobbling on the sliding platform 23, the electric telescopic rod 24 directly drives the insulation sealing plate 21 to press against the furnace body 1, so that the insulation sealing plate 21 can fit tightly against the furnace body 1 at all points, thereby improving the insulation and sealing capacity. At the same time, since the sealing is mainly achieved by the electric telescopic rod 24, the connecting platform 22 and the sliding platform 23 on the front side can be quickly disassembled and assembled using the clamp 25, thus making it easy to close the insulation sealing plate 21. And open, finally, the outer side of the first rotating rod 531 is movably sleeved on the inner side of the mounting groove 4, push the slide rod 52 to the right, so that the slide rod 52 drives the second rotating rod 533 to move to the right, thereby causing the first rotating rod 531 to move upward, so that the upper side of the first rotating rod 531 abuts against the upper inner side of the mounting groove 4. The second rubber pad is used to prevent rigid contact between the push block 54 and the heat insulation sealing plate 21, which would cause excessive compression between the components and deformation. The second rubber pad can be made of high temperature resistant rubber. The shape of the mounting groove 4 makes the first After the rotating rod 531 presses against the upper inner side of the mounting groove 4, the tray 51 moves down relative to the first rotating rod 531 and contacts the bottom inner side of the mounting groove 4, preventing the tray 51 from moving back and forth. The heat insulation sealing plate 21 presses against the push block 54, so that the first rotating rod 531 presses against the upper inner surface of the mounting groove 4, preventing the tray 51 from moving in the mounting groove 4, and fixing the tray 51 in the furnace body 1, thus preventing the ceramic products from falling off the tray 51 due to the movement of the tray 51 in the furnace body 1.
