Description

Technical Field

[0001] The utility model relates to the technical field of ceramic manufacturing, in particular to a high-temperature ceramic sintering furnace. Background Art

[0002] A high-temperature ceramic sintering furnace is a device used for sintering ceramic materials. Sintering refers to heating ceramic powder at a high temperature to cause chemical reactions between its particles to form a dense ceramic blank. This sintering process requires high temperature and long-time heating, so special sintering equipment is needed.

[0003] However, in the prior art, after the staff uses the high-temperature ceramic sintering furnace to complete the firing of ceramics, due to the high temperature inside the ceramic sintering furnace, when opening the door, since the staff usually stands in front of the door panel to open the door, it is easy to be scalded by the high-temperature hot air in the front, which is quite dangerous. Moreover, after the ceramics are fired, the fired ceramics need to be taken out. However, the temperature inside the sintering furnace just after firing is relatively high, and the worker is easy to be scalded by the high temperature emitted inside when taking the ceramics, and it is also not convenient to take.

One end of each of the two first fixing connection blocks is fixedly installed at the top end inside the sintering furnace shell. Heating resistors are fixedly installed on both sides of the surface of the alumina heat-conducting enclosure. A heat-insulating enclosure is fixedly wrapped around the surface of the alumina heat-conducting enclosure. The surfaces of the other sides of the two heating resistors are connected to the inner wall of the heat-insulating enclosure. The surfaces of the two first fixing connection blocks are embedded and penetrate through the top of the heat-insulating enclosure. First limiting grooves are formed on both sides of the inner wall of the bottom of the alumina heat-conducting enclosure. Second fixing connection blocks are fixedly installed on both sides of the bottom of the alumina heat-conducting enclosure. The surfaces of the two second fixing connection blocks are embedded and penetrate through the bottom of the heat-insulating enclosure.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0012] 1. For this utility model, place the device on the ground, connect the high-temperature resistant motor, high-temperature resistant reversible motor, and heating resistor to an external power supply and a control terminal. Place the ceramic clay block on the top of the heat-insulating firing plate, then hold the door handle to close the sintering furnace door panel, making the surface of the heat-insulating plate fit the surface of the alumina heat-conducting enclosure panel, and rotate two lock blocks into two L-shaped lock catches for locking. Control the power supply to energize the heating resistor through the control terminal. The heating resistor generates heat when energized and dissipates heat to the inside through the alumina heat-conducting enclosure panel. Since the alumina heat-conducting plate has high heat conductivity, the heat passes through the alumina heat-conducting enclosure panel to fire the ceramic clay block inside the alumina heat-conducting enclosure panel. When the ceramic sintering furnace finishes working, the staff unlocks the two lock blocks from the inside of the two L-shaped lock catches on both sides. Then, the staff starts the high-temperature resistant motor through the control terminal. The output end of the high-temperature resistant motor rotates, driving the second connecting shaft fixedly connected to it to rotate together. The second connecting shaft rotates to drive the micro winch fixedly connected to it to rotate. The rotation of the micro winch causes the steel wire rope wound around its surface to tighten. The tightening of the steel wire rope drives the first pulley and the second pulley attached to its surface to rotate. At the same time, the first fixing block and the second fixing block limit the steel wire rope. The tightening of the steel wire rope drives the third fixing block fixedly connected to its surface to move. The movement of the first pulley drives the sintering furnace door panel fixedly connected to it to open in a fan shape, thus being able to open the sintering furnace door panel, avoiding the problem that when the ceramic is fired and the staff needs to open the door, the staff is easily scalded by the high-temperature hot air in the front, which is relatively dangerous.

[0013] 2. For this utility model, after the sintering furnace door panel is opened, the staff starts the high-temperature resistant reversible motor through the control terminal. The output end of the high-temperature resistant reversible motor rotates, driving the third connecting shaft fixedly connected to it to rotate together, and at the same time driving the two gears fixedly sleeved on its surface to rotate. The rotation of the two gears drives the two racks meshing on their surfaces to translate. The translation of the two racks drives the heat-insulating firing plate fixedly connected to them to translate synchronously. At the same time, the door handle limits the rack, the two limit grooves limit the two second limit sliders, and the third connecting shaft limits the third through groove, so that a part of the heat-insulating firing plate always remains inside the sintering furnace shell, and at the same time ensuring that the heat-insulating firing plate will not shift, thus being able to automatically move the fired ceramic out of the sintering furnace, avoiding the problem that when the ceramic needs to be taken out after being fired, the worker is easily scalded by the high temperature emitted inside when taking the ceramic, and it is also not convenient to take.

[0026] Specifically: By holding the door handle 105, the sintering furnace door panel 101 is closed, and when the sintering furnace door panel 101 is closed, the surface of the heat insulation plate 107 fits the surface of the alumina heat conduction enclosure plate 301, and the two locking blocks 103 are rotated into the two L-shaped locking buckles 104 to lock the sintering furnace door panel 101. The sintering furnace door panel 101 is automatically opened through the pulley assembly 2, the ceramics are fired through the firing assembly 3, and the ceramics can be automatically moved out after being fired through the moving assembly 4.

[0027] In one embodiment, the pulley assembly 2 includes a clamping plate 201, a first fixing block 206, a second fixing block 210, and a third fixing block 214. A high-temperature resistant motor 202 is fixedly installed at the top of the clamping plate 201. The output end of the high-temperature resistant motor 202 is fixedly connected to a second connecting shaft 203. Both ends of the surface of the second connecting shaft 203 are embedded inside both ends of the clamping plate 201 through bearings. A micro winch 204 is fixedly sleeved on the surface of the second connecting shaft 203. A steel wire rope 205 is wound and connected to the surface of the micro winch 204. A first through groove 207 is formed through the inside of the first fixing block 206. Both sides of the inner cavity of the first through groove 207 are movably connected to a first rotating shaft 208 through bearings. A first pulley 209 is fixedly sleeved on the surface of the first rotating shaft 208. A second through groove 211 is formed through the surface of the second fixing block 210. Both sides of the inner cavity of the second through groove 211 are movably connected to a second rotating shaft 212 through bearings. A second pulley 213 is fixedly sleeved on the surface of the second rotating shaft 212. The surface of the steel wire rope 205 fits the inner sides of the first pulley 209 and the second pulley 213. One end of the steel wire rope 205 is fixedly connected to the surface of the micro winch 204, and the other end of the steel wire rope 205 is fixedly connected to one side of the third fixing block 214. The clamping plate 201 is fixedly installed at one end of one side surface of the sintering furnace outer shell 1, the first fixing block 206 is fixedly installed at the other end of one side surface of the sintering furnace outer shell 1, the second fixing block 210 is fixedly installed on one side of the surface of the sintering furnace door panel 101, and the third fixing block 214 is fixedly installed on the other side of the surface of the locking block 103.

[0028] Specifically: The high-temperature resistant motor 202 is started through the control terminal. The output end of the high-temperature resistant motor 202 rotates, driving the second connecting shaft 203 fixedly connected thereto to rotate together. The rotation of the second connecting shaft 203 drives the miniature winch 204 fixedly connected thereto to rotate. The rotation of the miniature winch 204 causes the steel wire rope 205 wound on its surface to tighten. The tightening of the steel wire rope 205 drives the first pulley 209 and the second pulley 213 attached to its surface to rotate. At the same time, the first fixing block 206 and the second fixing block 210 limit the steel wire rope 205. The tightening of the steel wire rope 205 drives the third fixing block 214 fixedly connected to its surface to displace. The displacement of the first pulley 209 drives the sintering furnace door plate 101 fixedly connected thereto to open in a fan shape, so that the sintering furnace door plate 101 can be opened. The first fixing block 206 and the second fixing block 210 are correspondingly arranged on both sides of the corner of the sintering furnace housing 1 and extend a certain length, so that the internal first pulley 209 and the second pulley 213 are respectively at a certain distance from the sintering furnace housing 1 and the sintering furnace door plate 101. When the sintering furnace door plate 101 is closed, the steel wire rope 205 will not rub against one side of the sintering furnace housing 1 or one side of the sintering furnace door plate 101 when being pulled.

[0029] In one embodiment, the firing assembly 3 includes an alumina heat-conducting enclosure 301. Both sides of the top of the alumina heat-conducting enclosure 301 are fixedly installed with first fixing connection blocks 302. One ends of the two first fixing connection blocks 302 are fixedly installed at the top end inside the sintering furnace housing 1. Both sides of the surface of the alumina heat-conducting enclosure 301 are fixedly installed with heating resistors 303. The surface of the alumina heat-conducting enclosure 301 is fixedly wrapped with a heat-insulating enclosure 304. The surfaces of the other sides of the two heating resistors 303 are connected to the inner wall of the heat-insulating enclosure 304. The surfaces of the two first fixing connection blocks 302 are embedded through the top of the heat-insulating enclosure 304. Both sides of the inner wall of the bottom of the alumina heat-conducting enclosure 301 are provided with first limiting grooves 305. Both sides of the bottom of the alumina heat-conducting enclosure 301 are fixedly installed with second fixing connection blocks 306. The surfaces of the two second fixing connection blocks 306 are embedded through the bottom of the heat-insulating enclosure 304. One ends of the two second fixing connection blocks 306 are fixedly installed at the bottom end of the inner cavity of the sintering furnace housing 1.

[0030] Specifically: The ceramic mud block is heated through the heating resistor 303. The heat is transferred through the alumina heat-conducting enclosure 301. The alumina heat-conducting enclosure 301 and the heating resistor 303 are wrapped on all four sides by the heat-insulating enclosure 304. Since both the heat-insulating bearing plate 401 and the heat-insulating enclosure 304 are made of high-temperature resistant ceramic fiber materials, heat insulation treatment can be carried out on external materials. The alumina heat-conducting enclosure 301 is supported by the first fixing connection block 302 and the second fixing connection block 306.

[0031] In one embodiment, the moving component 4 includes a heat-insulating bearing plate 401 and a high-temperature-resistant forward and reverse motor 410. Limiting sliders II 402 are fixedly installed on both sides of the heat-insulating bearing plate 401. A connecting block 403 is fixedly installed at the center of the bottom of the heat-insulating bearing plate 401. A through groove III 404 is formed through the surface of the connecting block 403. A limiting groove II 405 is formed at the center of the bottom of the connecting block 403. Rack bars 406 are fixedly installed at both ends of the bottom of the heat-insulating bearing plate 401. Gears 407 are meshed and connected to the bottoms of the two rack bars 406. Connecting shafts III 408 are fixedly and penetratingly embedded on the surfaces of the two gears 407. Connecting shaft fixing blocks 409 are movably sleeved at both ends of the connecting shaft III 408. One ends of the two connecting shaft fixing blocks 409 are fixedly installed at the bottom of the alumina heat-conducting enclosure plate 301. The surfaces of the two connecting shaft fixing blocks 409 are penetratingly embedded in the bottom of the heat-insulating enclosure plate 304. The high-temperature-resistant forward and reverse motor 410 is fixedly installed at the bottom end of one side surface of the sintering furnace shell 1. The output end of the high-temperature-resistant forward and reverse motor 410 penetrates through the surface of one side of the sintering furnace shell 1 and is fixedly connected to one end of the connecting shaft III 408.

[0032] Specifically: The high-temperature-resistant forward and reverse motor 410 is started through the control terminal. The rotation of the output end of the high-temperature-resistant forward and reverse motor 410 drives the connecting shaft III 408 fixedly connected thereto to rotate together, and at the same time drives the two gears 407 fixedly sleeved on its surface to rotate. The rotation of the two gears 407 drives the two rack bars 406 meshed on their surfaces to translate. The translation of the two rack bars 406 drives the heat-insulating bearing plate 401 fixedly connected thereto to translate synchronously. At the same time, the rack bar 406 is limited by the door handle 105, the two limiting sliders II 402 are limited by the two limiting grooves I 305, and the connecting shaft III 408 limits the through groove III 404, so that a part of the heat-insulating bearing plate 401 can always be located inside the sintering furnace shell 1, and at the same time, it is ensured that the heat-insulating bearing plate 401 will not shift.

[0033] In one embodiment, the two limiting sliders II 402 are both movably embedded in the two limiting grooves I 305, and the limiting slider I 106 is movably embedded in the limiting groove II 405.

[0034] Specifically: By movably embedding the two limiting sliders II 402 in the two limiting grooves I 305 and movably embedding the limiting slider I 106 in the limiting groove II 405, the limiting effect can be achieved.

[0035] In one embodiment, the surface of the connecting shaft III 408 moves inside the through groove III 404, and the lock block 103 moves inside the L-shaped lock catch 104.

[0036] Specifically, by moving the surface of the connecting shaft three 408 inside the through groove three 404, limiting can be achieved. By moving the lock block 103 inside the L-shaped lock catch 104, locking can be achieved.

[0037] Working principle: Place the device on the ground. Connect the high-temperature resistant motor 202, the high-temperature resistant reversible motor 410, and the heating resistor 303 to an external power supply and a control terminal. Place the ceramic clay block on the top of the heat-insulating firing plate 401. Then hold the door handle 105 to close the sintering furnace door panel 101, so that the surface of the heat-insulating plate 107 fits the surface of the alumina heat-conducting enclosure plate 301, and rotate the two lock blocks 103 into the two L-shaped lock catches 104 for locking. Control the power supply to energize the heating resistor 303 through the control terminal. The heating resistor 303 generates heat when energized and dissipates heat to the inside through the alumina heat-conducting enclosure plate 301. Due to the high heat-conducting performance of the alumina heat-conducting plate, the heat burns the ceramic clay block inside the alumina heat-conducting enclosure plate 301 through the alumina heat-conducting enclosure plate 301. When the ceramic sintering furnace finishes working, the staff unlocks the two lock blocks 103 from the inside of the two L-shaped lock catches 104 on both sides. Then the staff starts the high-temperature resistant motor 202 through the control terminal. The output end of the high-temperature resistant motor 202 rotates, driving the connecting shaft two 203 fixedly connected to it to rotate together. The rotation of the connecting shaft two 203 drives the miniature winch 204 fixedly connected to it to rotate. The rotation of the miniature winch 204 causes the steel wire rope 205 wound around its surface to tighten. The tightening of the steel wire rope 205 drives the pulley one 209 and the pulley two 213 attached to its surface to rotate. At the same time, the steel wire rope 205 is limited by the fixing block one 206 and the fixing block two 210. The tightening of the steel wire rope 205 drives the fixing block three 214 fixedly connected to its surface to displace. The displacement of the pulley one 209 drives the sintering furnace door panel 101 fixedly connected to it to open in a fan shape, thus avoiding the problem that when the ceramic is fired and the staff needs to open the door, the staff is easily scalded by the high-temperature hot air in the front, which is relatively dangerous. After the sintering furnace door panel 101 is opened, the staff starts the high-temperature resistant reversible motor 410 through the control terminal. The output end of the high-temperature resistant reversible motor 410 rotates, driving the connecting shaft three 408 fixedly connected to it to rotate together, and at the same time driving the two gears 407 fixedly sleeved on its surface to rotate. The rotation of the two gears 407 drives the two racks 406 engaged on their surfaces to translate. The translation of the two racks 406 drives the heat-insulating firing plate 401 fixedly connected to them to translate synchronously. At the same time, the door handle 105 limits the racks 406, the two limit grooves one 305 limit the two limit sliders two 402, and the connecting shaft three 408 limits the through groove three 404, so that the heat-insulating firing plate 401 always remains partially inside the sintering furnace housing 1, and at the same time ensures that the heat-insulating firing plate 401 will not shift, thus being able to automatically move the fired ceramic out of the sintering furnace, avoiding the problem that when the ceramic needs to be taken out after being fired, the worker is easily scalded by the high temperature emitted inside when taking the ceramic, and it is also not convenient to take.
