Description

Technical Field

[0001] The invention belongs to the technical field of ceramic media, in particular to a ceramic medium. Background Art

[0002] Dielectric ceramics (MWDC) refer to ceramics used as dielectric materials in microwave frequency bands (mainly UHF and SHF bands, 300MHz to 300GHz) circuits and perform one or more functions. It is a hot topic in the field of microwave dielectric material research at home and abroad in recent years. This is mainly to meet the development needs of microwave mobile communications, and is mainly used as microwave components such as resonators, filters, dielectric antennas, and dielectric waveguide circuits. It can be used in mobile communications, satellite communications, and military radars. With the rapid development of science and technology, the rapid increase in the amount of communication information, and people's requirements for wireless communications, the use of microwave communication systems such as satellite communications and satellite live TV has become an inevitable trend in the development of current communication technology. Another problem with conventional ceramic dielectrics is that they undergo a large volume change during firing. This type of dielectric is usually made by mixing raw materials such as clay, feldspar, talc, calcium silicate, zircon sand, and other mineral materials that form ceramics. The mixture then becomes a molding mixture and forms a so-called "green body", which has the shape of the required ceramic dielectric, but does not yet have physical properties, and is converted into a dielectric after high-temperature firing. During the sintering process, the above components undergo a series of interactions among solid phase, liquid phase, and gas phase combustion mechanisms to generate the required ceramic material. For an introduction to ceramic dielectrics, please refer to the journal: Li Shaokui, Huang Jianbang, Li Shuiyan, Cao Zhixue, Research on Sintering Technology of Single-layer Ceramic Dielectric Substrates, Electronic Components and Materials, 2016(03). However, there are still some problems in the production process of ceramic dielectrics, including the following aspects:

[0003] The sintering devices for firing ceramic media in the prior art are too conventional. Most of them place the ceramic substrate in a sintering box for combustion. However, this sintering method cannot burn the ceramic substrate in all directions, resulting in insufficient combustion of the ceramic substrate and affecting the quality of the ceramic substrate. At the same time, since this type of combustion method cannot ensure the full combustion of the ceramic substrate, it can only increase the combustion time of the ceramic substrate to compensate for this problem. However, the ceramic combustion time process will cause the ceramic to crack and waste gas.

[0004] There are also some solutions about ceramic media in the prior art, such as patent No. 02810023.9, whose patent name is patent for ceramic media. This technical solution uses a conventional sintering device in the process of making ceramic media, which cannot ensure the full-scale combustion of the ceramic matrix, affecting the quality of the ceramic matrix.

[0005] In view of this, in order to overcome the above technical problems, our company designed and developed a ceramic medium and produced a special sintering device to solve the above technical problems. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, the present invention proposes a ceramic medium. The present invention is mainly used to solve the problem that the sintering device puts the ceramic substrate into a sintering box for combustion. However, this sintering method cannot burn the ceramic substrate in all directions, resulting in insufficient combustion of the ceramic substrate, affecting the quality of the ceramic substrate. At the same time, since this type of combustion method cannot ensure the full-scale combustion of the ceramic substrate, it can only increase the combustion time of the ceramic substrate to compensate for this problem. However, the ceramic combustion time process may cause the ceramic to crack, and also waste gas.

[0007] The technical solution adopted by the present invention to solve the technical problem is: a ceramic medium, and the method for making the graphene fiber comprises the following steps:

[0009] S2: Put the crushed raw materials in S1 into a grinder and add deionized water to finely grind the raw materials for 4-5 hours. The technical requirement of the raw materials after fine grinding is D50≤2.5u. The raw materials can be refined by grinding, so that the bonding between the raw materials is more firm.

[0010] S3: adding a coagulant to the finely ground raw material in S2 and making the raw material into a cylindrical tubular solid ceramic matrix, then placing the ceramic matrix into a sintering device and starting the sintering device; by making the raw material into a cylindrical ceramic matrix, the ceramic matrix can be heated evenly in the sintering device, thereby improving the sintering efficiency of the ceramic matrix;

[0011] S4: During the firing process of the ceramic substrate, the sintering box can drive the ceramic substrate to roll in the sintering box filled with fine sand, and oxygen and natural gas are introduced into the sintering box at the same time; the rotation of the ceramic substrate driven by the sintering box can make the ceramic substrate evenly heated in the sintering box, thereby improving the sintering degree of the ceramic substrate;

[0012] S5: After the ceramic matrix in S4 is sintered, the ceramic matrix is ​​taken out and ground. After the grinding, the ceramic particles are made into slurry, and the slurry is made into rectangular ceramics to obtain a ceramic medium;

[0013] Wherein, the sintering device comprises a sintering box; a storage box is fixedly connected to the left outer surface of the sintering box, and fine sand is filled in the storage box; the storage box is connected to the sintering box through uniformly arranged first through holes; a first turntable is fixedly connected to the right side of the sintering box through a first air pipe; a motor is fixedly connected to the right end face of the first turntable, and the motor is electrically connected to the controller through a wire; the first air pipe is designed to extend out of the motor; the first air pipe is used to introduce oxygen; support rods are rotatably connected to the inner walls on both sides of the first turntable; the outer surfaces of the two support rods are rotatably connected to the first electric telescopic rods; the structure of the left end face of the storage box is the same as that of the right end face of the sintering box; the first air pipe on the left is used to introduce gas; A fire starter is installed in the wall; the inner surface of the sintering box is fixedly connected with uniformly arranged arc strips; the inner wall of the sintering box is provided with an arc groove, and the arc groove is connected with the first air pipe on the left; the inner wall of the arc groove is provided with uniformly arranged slot holes, and the slot holes are connected with the cavity in the sintering box; the second electric telescopic rods are fixedly connected to the positions on both sides of the sintering box in the cavity of the sintering box, and the second electric telescopic rods are electrically connected to the controller through wires; the outer surface of the electric telescopic rods is fixedly connected with a push layer on the opposite side of the two electric telescopic rods, and the push layers are semicircular in design and designed around the cavity in the sintering box; the inner walls of the two push layers are provided with uniformly arranged arc openings; the inner wall of the wire body is provided with an outlet, and a control valve is installed in the outlet;

[0014] During operation, the sintering devices for firing ceramic media in the prior art are too conventional. Most of them place the ceramic substrate in a sintering box for combustion. However, this sintering method cannot burn the ceramic substrate in all directions, resulting in insufficient combustion of the ceramic substrate, affecting the quality of the ceramic substrate. At the same time, since this type of combustion method cannot ensure the full combustion of the ceramic substrate, it can only increase the combustion time of the ceramic substrate to compensate for this problem. However, the ceramic combustion time process may cause the ceramic to crack, and also waste fuel gas. The sintering device made by the present invention can burn and conduct heat to the ceramic substrate in all directions by filling fine sand in the sintering box and burning it, thereby accelerating the combustion efficiency of the ceramic substrate and saving resources. When making the sintering device, first, the cylindrical tubular solid ceramic matrix is ​​placed into the sintering box through the outlet. At this time, the controller controls the control valve to be closed. Then, the controller controls the left first electric telescopic rod to extend. Since the sintering box is rotatably connected to the first electric telescopic rod, the first electric telescopic rod is prevented from getting stuck in the sintering box. When the left first electric telescopic rod is extended, the controller controls the motor to rotate, thereby driving the sintering box to rotate. During the rotation of the sintering box, the fine sand in the storage box can flow into the sintering box through the evenly arranged first through holes. When the fine sand completely flows into the sintering box, the controller controls the first electric telescopic rod to return to its initial state. At the same time, fuel gas is introduced into the sintering box through the left first air pipe, and oxygen is introduced into the sintering box through the right first air pipe. At this time, the controller controls the first electric telescopic rod to return to its initial state. At the same time, fuel gas is introduced into the sintering box through the left first air pipe, and oxygen is introduced into the sintering box through the right first air pipe. The controller controls the ignition of the lighter, and after the ignition of the lighter, the introduced gas can be ignited. When the gas is ignited, the fine sand and the cylindrical tubular solid ceramic matrix in the sintering box will be burned. Since the first gas pipe on the left is connected with the arc groove, the gas in the first gas pipe can flow into the arc groove, and the gas flowing into the arc groove can be ejected to the outside through the evenly arranged slot holes. In this process, the fine sand in the sintering box can be heated evenly. Since the sintering box is rotating, the fine sand can be buried with the ceramic matrix during the rotation of the sintering box. In this process, the fine sand and the ceramic matrix can be evenly burned, and the ceramic matrix can also be evenly heated, thereby improving the combustion degree of the ceramic matrix. Since the fine sand has a strong thermal conductivity, the fine sand can be heated in the process of gas burning the fine sand. The fine sand can be heated quickly, so that the heat in the fine sand can be transferred to the ceramic matrix. In this process, the ceramic matrix can be heated evenly, thereby improving the sintering efficiency of the ceramic matrix. Since the ceramic matrix is ​​a tubular design, the fine sand can flow into the interior of the ceramic matrix. In this process, the heating degree of the ceramic matrix can be further improved, thereby preventing the ceramic matrix from being heated unevenly. At the same time, the fine sand can also grind the ceramic matrix, thereby improving the smoothness of the ceramic matrix. During the rotation of the sintering box, the controller controls the second electric telescopic rod to perform telescopic movement. During the extension and retraction of the second electric telescopic rod, the push layer can be driven to perform telescopic movement. In this process, the fine sand in the sintering box can be pushed, and the fine sand is accumulated in the center of the sintering box, so that the fine sand can completely surround the ceramic matrix.In this process, the degree of heating of the ceramic matrix can be further improved, thereby preventing the uneven heating of the ceramic matrix from affecting the quality of the ceramic matrix. At the same time, fine sand can be pushed into the cavity of the ceramic matrix, so that the fine sand can conduct heat to the inside of the ceramic matrix. In this process, the ceramic matrix can be further heated evenly, and the sintering efficiency of the ceramic matrix can be improved, thereby saving the use of gas. When the sintering of the ceramic matrix is ​​completed, the first conduit of the controller stops introducing gas, and at the same time controls the second electric telescopic rod to extend to the midline position. When the two push layers are attached to each other, the second electric telescopic rod stops extending. In this process, the ceramic substrate can be pushed into the two push layers. At this time, the controller controls the first electric telescopic rod on the right to extend upward. When the sintering box is tilted, it stops extending. At this time, during the rotation of the sintering box, fine sand can be sieved into the storage box through the first through hole. Since the inner wall of the push layer is provided with evenly arranged arc-shaped openings, the fine sand in the push layer can be sieved into the sintering box and then sieved into the storage box through the first through hole. When the fine sand is completely sieved into the storage box, the controller controls the first electric telescopic rod to return to the initial position and controls the motor to stop rotating. Then, the ceramic substrate can be taken out through the outlet.

[0015] Preferably, the inner walls of the two push layers are provided with air grooves, and the air grooves are both arc-shaped; the two air grooves are both connected to the first air pipe on the right side; the inner walls of the two air grooves are provided with evenly arranged air holes, and the air holes are both connected to the cavity in the sintering box;

[0016] During operation, since the air groove is connected with the first duct on the right side, the oxygen in the first duct can flow into the air groove, and the gas flowing into the air groove is ejected through the evenly arranged air holes. When the push layer is doing telescopic movement, the oxygen can be evenly filled in the sintering box, thereby improving the combustion efficiency. At the same time, the fine sand can be blown to the center of the sintering box, and the sintering speed of the ceramic medium can be increased, thereby reducing the use of fuel. In this process, the fine sand can be prevented from being too dispersed, thereby reducing the thermal conductivity of the fine sand to the ceramic matrix. In the process of the push layer wrapping the ceramic matrix, the ceramic matrix and the fine sand in the push layer can be blown off, thereby preventing the fine sand from remaining in the ceramic matrix and affecting the quality of the ceramic matrix.

[0017] Preferably, the inner surfaces of the two push layers are fixedly connected with uniformly arranged arc rods, and the arc rods are all made of elastic metal materials; an arc cavity is opened in the inner wall of each arc rod, and the arc cavity is connected to the air groove; an arc hole is opened in the inner wall of each arc cavity, and the arc hole is connected to the outside;

[0018] During operation, since the inner surface of the push layer is fixedly connected with evenly arranged arc rods, the arc rods can increase the ability of the push layer to push the fine sand during the telescopic movement of the push layer, so that the fine sand and the ceramic substrate can be better pushed to the center of the sintering box. In this process, the ceramic substrate can be evenly contacted with the fine sand, so that the ceramic substrate is evenly heated, and partial overheating of the ceramic substrate is prevented, which causes the ceramic substrate to crack. Since the arc cavity opened in the inner wall of the arc rod is connected to the air groove, the gas in the air groove can flow into the arc cavity, and the gas flowing into the arc cavity is ejected through the evenly arranged arc holes. In this process, the inner surface of the push layer can be blown, thereby preventing fine sand from remaining on the inner surface of the arc layer. At the same time, the wrapped ceramic substrate can also be blown, thereby further improving the cleaning effect of the ceramic substrate.

[0019] Preferably, a second air pipe is fixedly connected to the inner wall of the sintering box on the right side, and the second air pipe is connected to the first air pipe on the right side; the second air pipes are all extended into the second electric telescopic rod and are slidably connected to the second electric telescopic rod; the inner wall of the second air pipe is provided with uniformly arranged second through holes, and the second through holes are all connected to the outside;

[0020] During operation, since the second air pipe is connected with the first air pipe on the right, the gas in the first air pipe can flow into the second air pipe, and the gas flowing into the second air pipe can flow out to the outside through the evenly arranged second through holes. In the process of gas spraying, the inner wall of the push layer can be blown, thereby further preventing fine sand from adhering to the inner surface of the push layer.

[0021] Preferably, the inner wall of the second air pipe is provided with evenly arranged slide grooves, and the slide grooves are all connected to the second through hole; a tension rod is hinged in each of the slide grooves; the inner surfaces of the two push layers are fixedly connected with evenly arranged insertion rods, and the insertion rods are made of elastic metal material; each of the insertion rods is arc-shaped and extends into the slide groove;

[0022] During operation, since the inserted rod fixed in the inner wall of the push layer extends into the slide groove, the inserted rod can be driven to slide in the slide groove during the telescopic movement of the push layer, and the tension rod can be pushed to rotate during the sliding process. During the rotation of the tension rod, the second air pipe is coordinated to rotate, so that the ceramic matrix in the fine sand can be stirred. In this process, the position of the ceramic matrix can be further changed, so that the ceramic matrix can better contact with the fine sand, and then the ceramic matrix can be heated evenly. At the same time, during the jetting of the second through hole, the tension rod can be pushed to rotate, thereby increasing the movement degree of the tension rod.

[0023] Preferably, the inner wall of the sintering box is fixedly connected with evenly arranged circulation pipes, and the circulation pipes are partially extended out of the outside; the inner wall of each circulation pipe extending out of the outside is provided with evenly arranged circulation holes, and the circulation holes are connected to the outside;

[0024] During operation, since a circulation pipe is fixedly connected to the inner wall of the sintering box, the gas in the sintering box can flow into the circulation pipe, and part of the gas flowing into the circulation pipe can flow out to the outside through evenly arranged circulation holes. In this process, the gas pressure in the sintering box can be prevented from being too high, thereby affecting the sintering process of the ceramic matrix. Part of the gas in the circulation pipe can circulate into the sintering box, and in this process, the combustion rate of the gas can be increased, thereby improving the utilization rate of the fuel gas.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. The present invention sets an air groove. Since the air groove is connected with the first conduit on the right side, the oxygen in the first conduit can flow into the air groove. The gas flowing into the air groove is ejected through the evenly arranged air holes. When the push layer is performing telescopic movement, the oxygen can be evenly filled in the sintering box, thereby improving the combustion efficiency. At the same time, the fine sand can be blown to move to the center of the sintering box, and the sintering speed of the ceramic medium can be increased, thereby reducing the use of fuel. In this process, the fine sand can be prevented from being too dispersed, thereby reducing the thermal conductivity of the fine sand to the ceramic matrix.

[0027] 2. The present invention arranges arc rods. Since the inner surface of the push layer is fixedly connected with the evenly arranged arc rods, the arc rods can increase the ability of the push layer to push the fine sand during the telescopic movement of the push layer, so that the fine sand and the ceramic matrix can be better pushed to the center of the sintering box. In this process, the ceramic matrix can be evenly contacted with the fine sand, so that the ceramic matrix is ​​evenly heated, and the problem of partial overheating of the ceramic matrix and coking cracking of the ceramic matrix can be prevented. Since the arc cavity opened in the inner wall of the arc rod is connected with the air groove, the gas in the air groove can flow into the arc cavity, and the gas flowing into the arc cavity is ejected through the evenly arranged arc holes. In this process, the inner surface of the push layer can be blown, thereby preventing the fine sand from remaining on the inner surface of the arc layer. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Wherein, the sintering device comprises a sintering box 1; a storage box 11 is fixedly connected to the left outer surface of the sintering box 1, and the storage box 11 is filled with fine sand; the storage box 11 is connected to the sintering box 1 through uniformly arranged first through holes 12; the right side of the sintering box 1 is fixedly connected to a first turntable 13 through a first air pipe 14; a motor is fixedly connected to the right end face of the first turntable 13, and the motor is electrically connected to the controller through a wire; the first air pipe 14 extends out of the motor design; the first air pipe 14 is used to introduce oxygen; support rods are rotatably connected to the inner walls of both sides of the first turntable 13; the outer surfaces of the two support rods are rotatably connected to the first electric telescopic rods 15; the structure of the left end face of the storage box 11 is the same as the structure of the right end face of the sintering box 1; the first air pipe 14 on the left is used to introduce gas; the sintering box 1 A fire starter 16 is installed in the inner wall of the box 1; the inner surface of the sintering box 1 is fixedly connected with uniformly arranged arc strips; the inner wall of the sintering box 1 is provided with an arc groove 17, and the arc groove 17 is connected with the first air pipe 14 on the left; the inner wall of the arc groove 17 is provided with uniformly arranged slot holes 18, and the slot holes 18 are connected with the inner cavity of the sintering box 1; the second electric telescopic rods 19 are fixedly connected at both sides of the cavity of the sintering box 1, and the second electric telescopic rods 19 are electrically connected to the controller through wires; the two electric telescopic rods are fixedly connected with a push layer 2 on the outer surface of the electric telescopic rod on the opposite side, and the push layers 2 are semicircular in design and designed around the inner cavity of the sintering box 1; the inner walls of the two push layers 2 are provided with uniformly arranged arc openings; the inner wall of the wire body is provided with an outlet, and a control valve is installed in the outlet;

[0043] During operation, the sintering devices for firing ceramic media in the prior art are too conventional. Most of them place the ceramic substrate in a sintering box for combustion. However, this sintering method cannot burn the ceramic substrate in all directions, resulting in incomplete combustion of the ceramic substrate, affecting the quality of the ceramic substrate. At the same time, since this type of combustion method cannot ensure the full combustion of the ceramic substrate, it can only increase the combustion time of the ceramic substrate to compensate for this problem. However, the ceramic combustion time process may cause the ceramic to crack, and also waste fuel gas. The sintering device made by the present invention can burn and conduct heat to the ceramic substrate in all directions by filling fine sand in the sintering box 1 and burning it, thereby accelerating the combustion efficiency of the ceramic substrate and saving resources. When using the sintering device made by the present invention, firstly, the cylindrical tubular solid ceramic matrix is ​​placed into the sintering box 1 through the outlet. At this time, the controller controls the control valve to be closed. Then, the controller controls the left first electric telescopic rod 15 to be extended. Since the sintering box 1 is rotatably connected to the first electric telescopic rod 15, the first electric telescopic rod 15 is prevented from being stuck in the sintering box 1. When the left first electric telescopic rod 15 is extended, the controller controls the motor to rotate, thereby driving the sintering box 1 to rotate. During the rotation of the sintering box 1, the fine sand in the storage box 11 can flow into the sintering box 1 through the evenly arranged first through holes 12. When the fine sand completely flows into the sintering box 1, the controller controls the first electric telescopic rod 15 to be restored to its initial state. At the same time, the through holes 12 are opened. Gas is introduced into the sintering box 1 through the first gas pipe 14 on the left, and oxygen is introduced through the first gas pipe 14 on the right. At this time, the controller controls the igniter 16 to ignite. After the igniter 16 is ignited, the introduced gas can be ignited. When the gas is ignited, the fine sand and the cylindrical tubular solid ceramic matrix in the sintering box 1 will be burned. Since the first gas pipe 14 on the left is connected with the arc groove 17, the gas in the first gas pipe 14 can flow into the arc groove 17, and the gas flowing into the arc groove 17 can be ejected to the outside through the evenly arranged slot holes 18. In this process, the fine sand in the sintering box 1 can be heated evenly. Since the sintering box 1 is rotating, the fine sand can bury the ceramic matrix during the rotation of the sintering box 1. In this process, the fine sand and the ceramic matrix can be evenly heated. The combustion is carried out, and at the same time, the ceramic matrix can be evenly heated, thereby improving the combustion degree of the ceramic matrix. Since the fine sand has a strong thermal conductivity, the fine sand can be quickly heated during the combustion of the fine sand by the gas, so that the heat in the fine sand can be transferred to the ceramic matrix. In this process, the ceramic matrix can be evenly heated, thereby improving the sintering efficiency of the ceramic matrix. Since the ceramic matrix is ​​a tubular design, the fine sand can flow into the interior of the ceramic matrix, and in this process, the heating degree of the ceramic matrix can be further improved, thereby preventing the ceramic matrix from being heated unevenly. At the same time, the fine sand can also grind the ceramic matrix, thereby improving the smoothness of the ceramic matrix. During the rotation of the sintering box 1, the controller controls the second electric telescopic rod 19 to perform telescopic movement.During the extension and retraction of the second electric telescopic rod 19, the push layer 2 can be driven to perform a telescopic movement. During this process, the fine sand in the sintering box 1 can be pushed, so that the fine sand is accumulated in the center of the sintering box 1, so that the fine sand can completely surround the ceramic substrate. During this process, the heating degree of the ceramic substrate can be further improved, thereby preventing the uneven heating of the ceramic substrate from affecting the quality of the ceramic substrate. At the same time, the fine sand can be pushed into the cavity of the ceramic substrate, so that the fine sand can conduct heat to the inside of the ceramic substrate. During this process, the ceramic substrate can be further heated evenly, and the sintering efficiency of the ceramic substrate can be improved, thereby saving the use of gas. When the sintering of the ceramic substrate is completed, the controller stops introducing gas into the first conduit, and at the same time controls the second electric telescopic rod 19 to The second electric telescopic rod 19 stops extending when the two push layers 2 are attached to each other. During this process, the ceramic substrate can be pushed into the two push layers 2. At this time, the controller controls the first electric telescopic rod 15 on the right to extend upward. When the sintering box 1 is tilted, it stops extending. At this time, during the rotation of the sintering box 1, fine sand can be sieved into the storage box 11 through the first through hole 12. Since the inner wall of the push layer 2 is provided with evenly arranged arc-shaped openings, the fine sand in the push layer 2 can be sieved into the sintering box 1 and then sieved into the storage box 11 through the first through hole 12. When the fine sand is completely sieved into the storage box 11, the controller controls the first electric telescopic rod 15 to return to the initial position and controls the motor to stop rotating. Then, the ceramic substrate can be taken out through the outlet.

[0044] As an embodiment of the present invention, the inner walls of the two push layers 2 are provided with air grooves 21, and the air grooves 21 are arc-shaped; the two air grooves 21 are connected to the first air pipe 14 on the right side; the inner walls of the two air grooves 21 are provided with evenly arranged air holes 22, and the air holes 22 are connected to the cavity in the sintering box 1;

[0045] During operation, since the air groove 21 is connected with the first conduit on the right side, the oxygen in the first conduit can flow into the air groove 21, and the gas flowing into the air groove 21 is ejected through the evenly arranged air holes 22. When the push layer 2 is performing telescopic movement, the oxygen can be evenly filled in the sintering box 1, thereby improving the combustion efficiency. At the same time, the fine sand can be blown to move to the center of the sintering box 1, and the sintering speed of the ceramic medium can be increased, thereby reducing the use of fuel. In this process, the fine sand can be prevented from being too dispersed, thereby reducing the thermal conductivity of the fine sand to the ceramic matrix. In the process of the push layer 2 wrapping the ceramic matrix, the fine sand in the ceramic matrix and the push layer 2 can be blown off, thereby preventing the fine sand from remaining in the ceramic matrix and affecting the quality of the ceramic matrix.

[0046] As an embodiment of the present invention, the inner surfaces of the two push layers 2 are fixedly connected with uniformly arranged arc rods 23, and the arc rods 23 are all made of elastic metal materials; an arc cavity 24 is opened in the inner wall of each arc rod 23, and the arc cavity 24 is connected to the air groove 21; an arc hole 25 is opened in the inner wall of each arc cavity 24, and the arc hole 25 is connected to the outside;

[0047] During operation, since the inner surface of the push layer 2 is fixedly connected with the evenly arranged arc rods 23, during the telescopic movement of the push layer 2, the arc rods 23 can increase the ability of the push layer 2 to push the fine sand, thereby better pushing the fine sand and the ceramic matrix to the center of the sintering box 1. In this process, the ceramic matrix can be evenly contacted with the fine sand, so that the ceramic matrix is ​​evenly heated, and the ceramic matrix is ​​prevented from being partially overheated and causing the ceramic matrix to be scorched and cracked. Since the arc cavity 24 opened in the inner wall of the arc rod 23 is connected to the air groove 21, the gas in the air groove 21 can flow into the arc cavity 24, and the gas flowing into the arc cavity 24 is ejected through the evenly arranged arc holes 25. In this process, the inner surface of the push layer 2 can be blown, thereby preventing the fine sand from remaining on the inner surface of the arc layer. At the same time, the wrapped ceramic matrix can also be blown, thereby further improving the cleaning effect of the ceramic matrix.

[0048] As an embodiment of the present invention, a second air pipe 26 is fixedly connected to the inner wall of the sintering box 1 on the right side, and the second air pipe 26 is connected to the first air pipe 14 on the right side; the second air pipes 26 are all extended into the second electric telescopic rod 19 and are slidably connected to the second electric telescopic rod 19; the inner wall of the second air pipe 26 is provided with uniformly arranged second through holes 27, and the second through holes 27 are all connected to the outside;

[0049] During operation, since the second air pipe 26 is connected to the first air pipe 14 on the right side, the gas in the first air pipe 14 can flow into the second air pipe 26, and the gas flowing into the second air pipe 26 can flow out to the outside through the evenly arranged second through holes 27. In the process of gas spraying, the inner wall of the push layer 2 can be blown, thereby further preventing the inner surface of the push layer 2 from being adhered to fine sand.

[0050] As an embodiment of the present invention, the inner wall of the second air pipe 26 is provided with evenly arranged slide grooves 28, and the slide grooves 28 are all connected to the second through hole 27; each of the slide grooves 28 is hinged with a tension rod 29; the inner surfaces of the two push layers 2 are fixedly connected with evenly arranged insertion rods 291, and the material of the insertion rods 291 is made of elastic metal material; each of the insertion rods 291 is arc-shaped and extends into the slide groove 28;

[0051] During operation, since the inserted rod 291 fixed in the inner wall of the push layer 2 extends into the slide groove 28, the inserted rod 291 can be driven to slide in the slide groove 28 during the telescopic movement of the push layer 2. The tension rod 29 can be pushed to rotate during the sliding process of the inserted rod 291. During the rotation of the tension rod 29, the second air pipe 26 rotates in coordination, so that the ceramic matrix in the fine sand can be stirred. In this process, the position of the ceramic matrix can be further changed, so that the ceramic matrix can better contact with the fine sand, and then the ceramic matrix can be heated evenly. At the same time, during the jetting process of the second through hole 27, the tension rod 29 can also be pushed to rotate, thereby increasing the movement degree of the tension rod 29.

[0052] As an embodiment of the present invention, the inner wall of the sintering box 1 is fixedly connected with evenly arranged circulation pipes 191, and the circulation pipes 191 are partially extended out of the outside; the inner wall of each circulation pipe 191 extending out of the outside is provided with evenly arranged circulation holes, and the circulation holes are connected to the outside;

[0053] During operation, since a circulation pipe 191 is fixedly connected to the inner wall of the sintering box 1, the gas in the sintering box 1 can flow into the circulation pipe 191, and part of the gas flowing into the circulation pipe 191 can flow out to the outside through the evenly arranged circulation holes. In this process, the gas pressure in the sintering box 1 can be prevented from being too high, thereby affecting the sintering process of the ceramic matrix. Part of the gas in the circulation pipe 191 can circulate and flow into the sintering box 1. In this process, the combustion rate of the gas can be increased, thereby improving the utilization rate of the fuel gas.

[0054] The specific workflow is as follows:

[0055] During operation, when using the sintering device made by the present invention, firstly, the cylindrical tubular solid ceramic matrix is ​​placed into the sintering box 1 through the outlet, at which time the controller controls the control valve to be closed, and then the controller controls the left first electric telescopic rod 15 to be extended. Since the sintering box 1 is rotationally connected to the first electric telescopic rod 15, the first electric telescopic rod 15 is prevented from being stuck to the sintering box 1. When the left first electric telescopic rod 15 is extended, the controller controls the motor to rotate, thereby driving the sintering box 1 to rotate. During the rotation of the sintering box 1, the fine sand in the storage box 11 can flow into the sintering box 1 through the evenly arranged first through holes 12. When the fine sand completely flows into the sintering box 1, the controller controls the first electric telescopic rod 15 to return to its initial position. state, and at the same time, gas is introduced into the sintering box 1 through the first gas pipe 14 on the left, and oxygen is introduced through the first gas pipe 14 on the right. At this time, the controller controls the igniter 16 to ignite, and the introduced gas can be ignited after the igniter 16 is ignited. When the gas is ignited, the fine sand and the cylindrical tubular solid ceramic matrix in the sintering box 1 are burned. Since the first gas pipe 14 on the left is connected with the arc groove 17, the gas in the first gas pipe 14 can flow into the arc groove 17, and the gas flowing into the arc groove 17 can be ejected to the outside through the evenly arranged slot holes 18. Since the sintering box 1 is rotating, the fine sand can be buried with the ceramic matrix during the rotation of the sintering box 1. Since the fine sand has a strong thermal conductivity, the fine sand can be quickly burned in the process of gas burning the fine sand. The sintering box 1 is heated quickly, so that the heat in the fine sand can be transferred to the ceramic matrix. Since the ceramic matrix is ​​a tubular design, the fine sand can flow into the inside of the ceramic matrix. In this process, the heating degree of the ceramic matrix can be further improved, thereby preventing the ceramic matrix from being heated unevenly. During the rotation of the sintering box 1, the controller controls the second electric telescopic rod 19 to perform telescopic movement. During the extension and retraction of the second electric telescopic rod 19, the push layer 2 can be driven to perform telescopic movement. In this process, the fine sand in the sintering box 1 can be pushed, so that the fine sand is accumulated in the center position of the sintering box 1, so that the fine sand can completely surround the ceramic matrix. When the sintering of the ceramic matrix is ​​completed, the controller stops the gas from entering the first conduit, and at the same time controls the second electric telescopic rod 19 to extend to the center line position. When the two push layers 2 are attached to each other, the second electric telescopic rod 19 stops extending. During this process, the ceramic substrate can be pushed into the two push layers 2. At this time, the controller controls the first electric telescopic rod 15 on the right to extend upward. When the sintering box 1 is tilted, it stops extending. At this time, during the rotation of the sintering box 1, fine sand can be sifted into the storage box 11 through the first through hole 12. Since evenly arranged arc-shaped openings are opened in the inner wall of the push layer 2, the fine sand in the push layer 2 can be sifted into the sintering box 1 and then sifted into the storage box 11 through the first through hole 12. When the fine sand is completely sifted into the storage box 11, the controller controls the first electric telescopic rod 15 to return to its initial position and controls the motor to stop rotating. Then, the ceramic substrate can be taken out through the outlet.
