Description

Technical Field

[0001] The invention belongs to the technical field of ceramic material production, and in particular relates to an energy-saving ceramic material sintering device. Background Art

[0002] Ceramic materials are widely used in many fields because of their high hardness, high compressive strength, high melting point, good chemical stability, good insulation, low thermal expansion coefficient and other characteristics. For example, the application of bioceramics has good biological activity, and is similar to the tissue structure and chemical composition of organisms, and can directly act on the human body or biological, medical, biochemical and other related to the human body; the application in the field of new energy, including energy-saving thermal storage type thermal waste incinerator (RTO) and smelting industry energy-saving thermal storage chamber honeycomb ceramics, hot gas purification and water treatment fields for ceramic membranes and equipment, UHV AC transmission technology and equipment series; UHV suspension porcelain insulators, silicon carbide ceramic components for heat storage and heat exchange, photovoltaic industry series of ceramic products; application in the field of electronics, due to the high resistivity and high thermal conductivity of ceramic materials, they can be used to manufacture resistors, capacitors and other electronic components. The formation of ceramic materials requires the ceramic powder to be transformed into a green body through molding technology, and then the sintering technology is used to make the grains of the green body migrate and grow, and the body shrinks to form ceramic materials.

[0003] The core components of the ceramic material sintering device are mainly composed of a heating chamber, a heating element, and a sample carrier. Due to the limitation of the sample carrier, the output end of the heating element can generally only be set on the inner wall of the heating chamber. The heat flow formed by the heating element in the process of sintering the ceramic material flows from the edge of the heating chamber to the middle, which is manifested as the edge temperature of the heating chamber being higher than the center temperature. During use, although the heating chamber will be preheated at the beginning of heating so that the heating temperature reaches the specified range before the ceramic material is added, in order to maintain the constant heat inside the heating chamber, the heating element will continue to supply heat during the sintering process. At this time, there is a temperature difference in the contact temperature with the ceramic material at different positions, especially the parts close to and far from the side wall of the heating chamber. The temperature difference is obvious, which affects the quality of the sintered product. Although the flow of heat inside the heating chamber is increased by increasing the air pressure, that is, the existing pressurized sintering equipment improves the uniformity of heating of ceramic materials by changing the flow rate and direction of heat, this method actually reduces the temperature difference between the heat and different positions of the ceramic material. It has a good effect on the sintering of a single ceramic material, but has a poor effect on the sintering of batches of ceramic materials. The ceramic materials placed in batches will block each other, resulting in difficulty in sufficient and uniform heating of the ceramic materials. It is not applicable to some ceramic materials with higher quality precision requirements. Summary of the invention

[0046] See also Figures 1 to 4As shown, in order to achieve batch ceramic sintering while ensuring that each ceramic material is fully heated, the uniformity of heating is improved, and the yield of ceramic material sintering is improved. This embodiment provides an energy-saving ceramic material sintering device, including a heating cavity 1, a heating element and a carrying platform 2, and also includes a rotating disk 3, a gear mechanism 4 and a driving mechanism 5. The heating cavity 1 has an electric cavity door 21, a slide rail 22 is arranged at the bottom of the heating cavity 1, and the slide rail 22 extends from the inside of the heating cavity 1 to the outside of the heating cavity 1; the heating element is arranged outside the heating cavity 1, including a heater, a gas purification structure and a hot gas delivery pump, etc. The heater can be electromagnetic heating, electric heating wire heating or microwave energy heating, etc., and continuously releases hot gas into the heating cavity 1 through a pipeline to sinter the ceramic material. Furthermore, a plurality of rotating disks 3 are arranged, and the plurality of rotating disks 3 are distributed in a circumferential array on the upper side of the carrying platform 2, and the rotating disks 3 are used to place ceramic materials; the gear mechanism 4 includes a driving gear 41 and a plurality of driven gears 42, and the plurality of driven gears 42 correspond to the rotating disks 3 one by one, and the driven gears 42 and the corresponding rotating disks 3 are detachably connected to the upper and lower sides of the carrying platform 2 through the rotating rod 8, and the driven gears 42 are rotatably connected to the carrying platform 2, and the rotating rod 8 is inserted through the through hole reserved on the carrying platform 2, and the rotating rod 8 indirectly rotates with the carrying platform 2 through the driven gear 42, and the plurality of driven gears 42 are all meshed with the driving gear 41; the output end of the driving mechanism 5 is connected with the driving gear 41, and is used to drive the driving gear 41 to rotate, and the driving gear 41 is meshed with the plurality of driven gears 42, so that the plurality of driven gears 42 are synchronously rotated, and when the driven gear 42 rotates, the corresponding rotating disks 3 are driven to rotate synchronously through the rotating rod 8, so that the plurality of rotating disks 3 are indirectly rotated. And the bottom of the driving mechanism 5 is slidably connected with the track at the bottom of the heating chamber 1.

[0047] When sintering ceramic materials, after preheating the heating chamber 1, the electric chamber door 21 of the heating chamber 1 is opened to quickly push the supporting platform 2 and the rotating disk 3, gear mechanism 4 and driving mechanism 5 matched therewith into the heating chamber 1, and then close the electric chamber door 21. Subsequently, the driving mechanism 5 is started to provide the driving gear 41 with the power for rotation. During the rotation process, the driving gear 41 can realize the self-rotation of each rotating disk 3 by meshing with a plurality of driven gears 42, so that the entire outer contour of the ceramic material placed on the rotating disk 3 can be alternately rotated to display the heat contact with the edge of the chamber, and the process of driving the ceramic material to rotate by the rotating disk 3 will produce the effect of stirring the heat in the heating chamber 1, so that the ceramic materials placed in batches can be fully and evenly heated as a whole, thereby improving the yield rate of ceramic material sintering.

[0048] See also Figure 3 and Figure 4As shown, further, in order to improve the uniformity of heating of the ceramic material, the driving mechanism 5 includes a driver 51, a rotating shaft 52, a rotating sleeve 53 and a transmission gear set. The driver 51 can be a servo motor, and its output shaft is coaxially arranged with the rotating shaft 52, the rotating sleeve 53 and the driving gear 41, and the upper end of the rotating shaft 52 is fixedly connected to the bearing platform 2, and the lower end is fixedly connected to the output shaft; the rotating sleeve 53 is sleeved on the rotating shaft 52 and the two are rotatably connected, and the driving gear 41 is sleeved and fixed on the rotating sleeve 53; and the transmission gear set is arranged between the rotating shaft 52 and the rotating sleeve 53, and is used to realize that the rotating sleeve 53 rotates in the opposite direction to the rotating shaft 52. Specifically, the transmission gear set includes a stabilizing frame 54, a connecting shaft 55, a transmission bevel gear 56 and two driven bevel gears 57. The stabilizing frame 54 is U-shaped, and two opposite side walls are respectively sleeved on the rotating shaft 52 and the rotating sleeve 53, and the stabilizing frame 54 is fixed to the motor housing. The two driven bevel gears 57 are arranged opposite to each other and are respectively sleeved and fixed on the rotating shaft 52 and the rotating sleeve 53. The transmission bevel gear 56 is arranged between the two driven bevel gears 57 and is connected to the stable rotation, and the transmission bevel gears 56 are meshed with the two driven bevel gears 57.

[0049] When in use, the driver 51 directly drives the rotating shaft 52 to rotate. At this time, the driven bevel gear 57 on the rotating shaft 52 rotates and meshes with the transmission bevel gear 56, so that the transmission bevel teeth rotate, and the transmission bevel gear 56 then meshes with the driven bevel gear 57 on the rotating sleeve 53, so that the rotating sleeve 53 rotates, and the rotating sleeve 53 and the rotating shaft 52 rotate in opposite directions, so that the rotating shaft 52 can drive the bearing platform 2 to rotate, and the rotation of the bearing platform 2 enables the rotating disk 3 to realize orbital revolution, and the rotating sleeve 53 drives the driving gear 41 and the driven gear 42 to mesh and rotate, so as to realize the rotation of the rotating disk 3, so that the rotation and revolution of the rotating disk 3 can ensure that the outer contour of the ceramic material is in full contact with the heat inside the heating cavity 1, and at the same time, the rotating disk 3 can further fully mix the heat inside the heating cavity 1 with the rotation and revolution of the ceramic material, thereby improving the uniformity of heating of the ceramic material.

[0050] See also Figure 1 and Figure 5 As shown, further, in order to improve the uniformity of heating of the ceramic material inside the heating chamber 1. The guide platform 6 has a guide surface 7 facing the supporting platform 2. The guide surface 7 is inclined or has a wavy structure that is annularly wound around the rotating shaft 52. A plurality of rotating rods 8 of the same length are vertically arranged on the guide surface 7. The plurality of rotating rods 8 correspond to the rotating disk 3 and the driven gear 42 one by one. The upper end of the rotating rod 8 passes through the supporting platform 2 and is fixedly connected to the corresponding rotating disk 3, and the lower end abuts against the guide surface 7. The driven gear 42 is mounted on the rotating rod 8 and a sliding assembly 9 is arranged between the two. The sliding assembly 9 is used to realize the sliding of the driven gear 42 on the rotating rod 8 while the driven gear 42 drives the rotating rod 8 to rotate. For details, see Figure 6 , Figure 7 and Figure 8 As shown, the sliding assembly 9 includes a sleeve 91 and a sliding block 92. The sleeve 91 is sleeved on the rotating rod 8, the sleeve 91 is rotatably connected to the bearing platform 2, and the driven gear 42 is sleeved and fixed on the sleeve 91; the sliding block 92 is fixedly connected to the inner wall of the sleeve 91; and a sliding groove 93 adapted to the sliding block 92 is provided on the side wall of the rotating rod 8 in the vertical direction, and the sliding block 92 can slide up and down in the sliding groove 93. In addition, a guide platform 6 is provided at the bottom of the bearing platform 2. Preferably, a groove for installing the driver 51 and the transmission gear set is provided at the center of the guide platform 6, and a heat insulation cover is provided outside the groove to facilitate the reasonable installation of the driver 51 and the transmission gear set, and the heat insulation cover can well protect the driver 51. In addition, a sliding member adapted to the bottom guide rail of the heating chamber 1 is designed at the bottom of the guide platform 6, which can facilitate the delivery and removal of the bearing platform 2 into the heating chamber 1.

[0051] When in use, the supporting platform 2 will carry the rotating rod 8 to rotate on the guide surface 7 during the rotation process, so that the rotating rod 8 contacts the guide surface 7 at different positions, thereby utilizing the height difference of the guide surface 7 to enable the rotating rod 8 to push the corresponding rotating disk 3 to rise and fall in the vertical direction, thereby effectively causing the ceramic material to be in contact with the temperature in the vertical direction as a whole, reducing the temperature difference of the ceramic material being heated, and at the same time utilizing the up and down movement and rotation of the rotating disk 3 to achieve sufficient mixing of heat in the heating cavity 1, thereby improving the uniformity of heat distribution and the uniformity of heating of the ceramic material.

[0052] See also Figure 3 and Fig.11 As shown, further, in order to improve the uniformity of heating of ceramic materials, the heating element is designed to have two hot air delivery pumps, and the exhaust pipe 11 of one of the hot air delivery pumps is connected to multiple heating holes 12 arranged on the side wall of the heating cavity 1 through the shunt pipe 10. The preferred bearing platform 2 is easily set to a round pancake shape, and the side of the heating cavity 1 facing the cavity door is designed to be arc-shaped to match the bearing platform 2. Furthermore, multiple heating holes 12 are designed to be located on the upper side of the bearing platform 2 and are evenly distributed on the circumference of the bearing platform 2, and the exhaust pipe 11 of the other hot air delivery pump passes through the top wall of the heating cavity 1 and is placed inside the heating cavity 1, and is located on the upper side of the bearing platform 2.

[0053] Therefore, when in use, the heating holes 12 surrounding the side of the supporting platform 2 are used to heat from the outside of the heating cavity 1 to the center, and the exhaust pipe 11 inside the heating cavity 1 transfers heat from the middle to the edge, which can quickly increase the heat inside the heating cavity 1. At this time, the rotating disk 3 is between the inside and outside heat transfer directions, which can make the ceramic material quickly and evenly heated.

[0054] See also Fig.10As shown, in order to improve the heating uniformity of the ceramic material, a diffusion pipe 13 is fixedly connected to the upper side of the carrier platform 2, the diffusion pipe 13 is coaxial with the exhaust pipe 11 on the upper side of the carrier platform 2, the diffusion pipe is connected to the exhaust pipe 11 and the two are detachably connected, and a plurality of air outlet holes 14 are spirally distributed on the pipe wall of the diffusion pipe.

[0055] When in use, after the carrying platform 2 is pushed into the heating chamber 1, the diffuser is docked with the exhaust pipe 11 at the top, so that the hot air from the exhaust pipe 11 flows into the diffuser. At this time, the diffuser uses multiple air outlets to allow the hot air to diffuse better to the surroundings. At this time, the diffuser rotates along with the carrying platform 2, and the air outlets are spirally distributed, so that the hot air can form a three-dimensional diffusion effect on the rotating disk bearing, so that the heat diffused outward from the center line is more uniform, and the uniformity of heating of the ceramic material is improved. Preferably, in order to ensure that the diffuser is still in good rotation after docking with the exhaust pipe 11, a docking pipe 23 is respectively installed at the connecting end of the diffuser and the exhaust pipe 11, and electromagnetic suction cups are arranged on the opposite side walls of the two docking pipes 23. After the carrying platform 2 enters the heating chamber 1, the electromagnetic suction cups are energized to connect the two docking pipes 23, and the two docking pipes 23 rotate with the diffuser and the exhaust pipe 11 respectively, so as to ensure that the diffuser is still in good rotation after docking with the exhaust pipe 11.

[0056] See also Fig.10 As shown, further, in order to achieve a better diffusion effect of the hot gas output from the diffuser, a plurality of heat-leveling blades 15 are fixedly connected to the outer wall of the diffuser in a circumferential array, and a height difference is provided between two adjacent heat-leveling blades 15 in the vertical direction.

[0057] When in use, along with the rotation of the diffusion tube, the heat-averaging blades 15 will drive the high temperature in the middle to diffuse rapidly to the surroundings and mix with the temperature flowing in from the edges, thereby improving the uniformity of heat inside the heating cavity 1, that is, better ensuring the uniformity of heating of the ceramic material.

[0058] See also Figure 3 , Fig.11 and Fig.12 As shown, further, in order to improve the uniformity of heating of ceramic materials. A plurality of heating holes 12 are distributed in a circumferential array, and a connecting pipe 16 is inserted in each heating hole 12. One end of the connecting pipe 16 is connected to the shunt pipe 10 and the two are rotatably connected, and the other end extends to the heating cavity 1 and is fixedly connected to a heat sink 17, and a plurality of inclined flow channels 18 are provided on the heat sink 17. In addition, a ring gear 19 is fixedly connected to the edge of the upper side of the supporting platform 2, and the ring gear 19 is meshed with a plurality of linkage gears 20, and the plurality of linkage gears 20 are respectively fixed on a connecting pipe 16.

[0059] When in use, when the supporting platform 2 enters the interior of the heating chamber 1, the supporting platform 2 rotates and drives the annular gear 19 to engage with multiple interlocking gears 20, so that the connecting tube 16 can rotate. The rotation of the connecting tube 16 causes the flow direction of the hot air ejected from the heat sink 17 to change all the time, so that it can quickly diffuse in the entire heating chamber 1, so that the edge heat quickly diffuses to the middle, and is quickly mixed with the middle temperature under the rotation of the rotating disk 3, so as to achieve temperature balance in the heating chamber 1 and allow the ceramic material to be fully and evenly heated.

[0060] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
