Description

Technical Field

[0001] The present invention relates to the technical field of ceramic materials, and particularly to a production method and a production system for a silicon carbide honeycomb ceramic material. Background Art

[0002] Currently, the main way to solve the problem of automobile exhaust is to catalytically purify the automobile exhaust, and coating a catalytic material on a honeycomb ceramic is a catalytic purification method for automobile exhaust used in the existing technology.

[0003] Currently, the mainstream honeycomb ceramic is cordierite honeycomb ceramic, which has problems such as low thermal conductivity, unstable attachment of the catalyst to the inner wall of the honeycomb ceramic, and a narrow firing range, thus limiting its use. Silicon carbide honeycomb ceramic has excellent mechanical properties, high thermal conductivity, low thermal expansion coefficient and other characteristics, so it has good application prospects as a catalyst carrier.

[0004] Moreover, in the prior art, when producing silicon carbide honeycomb ceramic, a ball mill is needed for grinding the raw materials. The ball mill in the prior art cannot quickly and conveniently separate the grinding balls from the materials and collect and recycle the grinding balls. The ball mill is not convenient to use, resulting in relatively low raw material processing efficiency. In addition, the baffle used to block the feeding and discharging ports of the ball mill in the prior art is installed in a transmission hinge manner. When the baffle is subjected to the impact force generated by the ball mill, it is easy to loosen, resulting in poor sealing. Moreover, the space range passed by the baffle when opening and closing is large, and it is easy to interfere with the installation bracket. Summary of the Invention

[0005] In order to solve the problems mentioned in the above background art, the present invention provides a production method and a production system for a silicon carbide honeycomb ceramic material.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A production method for a silicon carbide honeycomb ceramic material includes the following steps:

[0008] S1: Put silicon carbide raw material particles into a ball mill, add absolute ethanol for wet grinding, filter the product and dry it to obtain silicon carbide powder, and filter and screen the silicon carbide powder to ensure that the diameter of the silicon carbide powder is 1μm - 2μm;

[0009] S2: Add silicon carbide powder into a mixer, and add a sintering aid, a dispersant and a forming medium into the mixer. The dispersant is a silane coupling agent, and the forming medium is a silicate. Prepare a honeycomb green body with parallel channels and dry it. The addition amount of silicon carbide powder is 60-75wt% of the total powder. The sintering aid is alumina powder and yttrium oxide powder. The addition amount of alumina powder is 2-5wt% of the total powder, and the addition amount of yttrium oxide powder is 5-10wt% of the total powder.

[0010] S3: Remove the organic matter from the honeycomb green body obtained in S2 by heat treatment. The heating temperature is 600-700 degrees Celsius, and the heating time is 1-2 hours. Then calcine the honeycomb green body at 1600-1700 degrees Celsius and keep it warm for 1-2 hours to obtain silicon carbide honeycomb ceramics.

[0011] A production system for silicon carbide honeycomb ceramic materials includes a ball mill, a mixer, an extrusion molding device and a muffle furnace. The ball mill is rotatably installed at the top of a support frame. There are multiple feeding and discharging ports on the ball mill, and an automatic sealing mechanism is provided on the feeding and discharging ports. And a material separation mechanism is provided below the ball mill.

[0012] Preferably, the material separation mechanism includes a receiving container. The receiving container is installed on the support frame in a lifting and sliding manner and is driven to lift by a hydraulic cylinder. Multiple filter rollers are rotatably installed on the receiving container.

[0013] Preferably, there are three filter rollers, and one of the filter rollers is driven to rotate by a first rotating motor. A first synchronous pulley is fixed at one end of the filter roller away from the first rotating motor. The adjacent first synchronous pulleys are synchronously driven by a belt.

[0014] Preferably, a discharge screw is installed near the bottom end inside the receiving container. A second synchronous pulley is installed on the discharge screw. The second synchronous pulley and one of the first synchronous pulleys are synchronously driven by a belt.

[0015] Preferably, a plurality of cleaning nozzles are installed on both sides of the top end of the receiving container. The cleaning nozzles face the filter rollers, and a plurality of spiral grooves are provided on the outside of the filter rollers.

[0016] Preferably, a toothed ring is provided outside the ball mill. A second rotating motor is installed on the support frame. A first gear is fixed at the output end of the second rotating motor. The first gear meshes with the toothed ring. A plurality of lifting baffles are provided inside the ball mill, and the lifting baffles extend radially along the cross section of the ball mill.

[0017] Preferably, an arc-shaped auxiliary support frame is fixed at the top end of the support frame. A plurality of support rollers are rotatably installed at the top end of the arc-shaped auxiliary support frame. The support rollers are in contact with the outer wall of the ball mill.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Put materials and grinding balls into the ball mill, and add anhydrous ethanol. The ball mill can rotate, and the grinding balls and materials interact with each other through gravity to mix and grind the materials. When the inlet and outlet are facing upward, open the automatic blocking mechanism to add materials into the ball mill. When the inlet and outlet are facing downward, open the automatic blocking mechanism to pour out the ground materials in the ball mill. It is simple and convenient to use, efficient and convenient.

[0020] 2. By adding a material separation mechanism, when the grinding balls and the material mixture fall into the receiving container together, the grinding balls will stay on the top of the filter roller, thereby achieving the purpose of separating the grinding balls and the materials. Since the height of the receiving container can be adjusted by the hydraulic cylinder drive, the receiving container can be lifted as close to the inlet and outlet as possible when unloading materials, reducing the impact force when the grinding balls fall, and preventing the material from splashing, so that the processing table of the device can be kept clean. When the ball mill is rotating, it can drive the receiving container to move downward away from the ball mill, so as not to affect the rotation of the ball mill, and it can be more convenient to clean and take out the grinding balls collected in the receiving container, so as to recycle them again;

[0021] 3. Through the design of the automatic blocking mechanism, the purpose of opening the inlet and outlet can be achieved by only turning on the third rotating motor. To close the inlet and outlet, the third rotating motor can be controlled to rotate in the opposite direction. It is simple and convenient to use. Compared with the baffle installed in a traditional hinged manner, there is no need to additionally set a locking buckle. The locking can be completed by the locking mechanism of the third rotating motor. In addition, since the freedom of movement of the blocking plate is limited by the arc guide rail, the blocking plate is not easy to loosen when it is subjected to the impact force generated by the ball mill. The baffle installed in a transmission hinged manner not only has a large space range when opening and closing, which is easy to interfere with the mounting bracket, but also is easy to loosen when impacted, resulting in a poor seal.

[0054] Example 4

[0055] Refer to Figures 1-14 , a production system for a silicon carbide honeycomb ceramic material, includes a ball mill 2, a mixer and a muffle furnace. The ball mill 2 is rotatably installed at the top of a support frame 1. A plurality of feed and discharge ports 202 are provided on the ball mill 2. An automatic sealing mechanism is provided on the feed and discharge ports 202, and a material separation mechanism is provided below the ball mill 2;

[0056] Materials and grinding balls are placed inside the ball mill 2, and anhydrous ethanol is added. The ball mill 2 can rotate and drive the grinding balls and the materials to interact with each other by gravity to mix and grind the materials. When the feed and discharge ports 202 face upward, the automatic sealing mechanism can be opened to add materials into the ball mill 2. When the feed and discharge ports 202 face downward, the automatic sealing mechanism can be opened to pour out the ground materials inside the ball mill 2. It is simple and convenient to use, efficient and convenient.

[0057] Example 5

[0058] Refer to Figures 1-14, the difference between this embodiment and Embodiment 4 is that the material separation mechanism includes a receiving container 4. The receiving container 4 is installed on the support frame 1 in a lifting and sliding manner and is driven to lift by a hydraulic cylinder 101. A plurality of filter rollers 401 are rotatably installed on the receiving container 4. The plurality of filter rollers 401 are arranged parallel to each other, and the distance between adjacent filter rollers 401 is smaller than the diameter of the grinding balls. After the grinding balls and the material mixture fall into the receiving container 4 together, the grinding balls will stay at the top of the filter rollers 401, so as to achieve the purpose of separating the grinding balls and the materials. Since the height of the receiving container 4 can be adjusted by driving the hydraulic cylinder 101, when feeding, the receiving container 4 can be lifted as close as possible to the position of the feeding and discharging port 202, reducing the impact force when the grinding balls fall, and preventing material splashing, so that the processing table surface of the device can be kept clean. When the ball mill 2 rotates and works, it can drive the receiving container 4 to move downward and away from the ball mill 2, so as not to affect the rotation of the ball mill 2, and it is more convenient to clean and take out the grinding balls collected in the receiving container 4, so as to be recycled again.

[0059] Among them, there are three filter rollers 401, and one of the filter rollers 401 is driven to rotate by a first rotating motor 404. A first synchronous pulley 402 is fixed at one end of the filter roller 401 away from the first rotating motor 404. The plurality of first synchronous pulleys 402 are synchronously driven by belts between adjacent ones. By the first rotating motor 404, the three filter rollers 401 can be driven to rotate at the same speed and in the same direction, so as to drive the grinding balls located between the two filter rollers 401 to roll continuously, so that the materials on the surface of the grinding balls are rubbed off, achieving the effect of actively cleaning the surface of the grinding balls. A plurality of cleaning nozzles 407 are installed on both sides of the top end of the receiving container 4. The cleaning nozzles 407 face the filter rollers 401. A plurality of spiral grooves 403 are arranged outside the filter rollers 401. In cooperation with the cleaning nozzles 407 spraying water towards the filter rollers 401 and the grinding balls, the grinding balls can be cleaned quickly and efficiently. The spiral grooves 403 on the surface of the filter rollers 401 can scrape off the materials on the surface of the grinding balls when rotating relative to the grinding balls, so as to accelerate the cleaning, and the cleaning nozzles 407 can flush the materials inside the spiral grooves 403.

[0060] Embodiment 6

[0061] Refer to Figures 1-14, the difference between this embodiment and Embodiment 5 is that a discharge screw 405 is installed near the bottom inside the receiving container 4. A second synchronous pulley 406 is installed on the discharge screw 405. The second synchronous pulley 406 is synchronously driven by a belt with one of the first synchronous pulleys 402. In order to accelerate the discharge of the separated material from the receiving container 4, the discharge screw 405 will rotate synchronously with the filter roller 401, thereby discharging the material. The discharged material is mixed with a sintering aid, a dispersant, and a forming medium in a mixer, and then a honeycomb green body with parallel channels is prepared by extrusion and dried. Finally, the honeycomb green body is placed in a muffle furnace for calcination.

[0062] Embodiment 7

[0063] Refer to Figures 1-14 , the difference between this embodiment and Embodiment 4 is that a toothed ring 201 is provided outside the ball mill 2. A second rotating motor 3 is installed on the support frame 1. A first gear 301 is fixed to the output end of the second rotating motor 3. The first gear 301 meshes with the toothed ring 201. A plurality of lifting baffles 203 are provided inside the ball mill 2. The lifting baffles 203 extend radially along the cross-section of the ball mill 2. By driving the first gear 301 to rotate through the second rotating motor 3, and then meshing the first gear 301 with the toothed ring 201, the whole ball mill 2 can be driven to rotate. During the rotation of the grinding balls, due to the existence of the lifting baffles 203, the grinding balls will get stuck at the top of the lifting baffles 203 during the rotation. When the lifting baffles 203 rotate from the vertically upward position to the horizontal position, the grinding balls will stay between the lifting baffles 203 and the inner wall of the ball mill 2 due to the action of gravity until the lifting baffles 203 continue to rotate, and then the grinding balls will roll down. At this time, the grinding balls will fall from the height of the inner radius of the ball mill 2 to the bottom, thereby improving the impact and friction effect between the grinding balls and the material by the action of gravity, and thus improving the ball milling effect.

[0064] Among them, an arc-shaped auxiliary support frame 102 is fixed to the top of the support frame 1. A plurality of support rollers 103 are rotatably installed at the top of the arc-shaped auxiliary support frame 102. The support rollers 103 are in contact with the outer wall of the ball mill 2. There are two arc-shaped auxiliary support frames 102, which can support the ball mill 2 from both ends of the ball mill 2. During the rotation of the ball mill 2, the support rollers 103 can provide a supporting force for the ball mill 2 from the bottom of the ball mill 2, ensuring the stability of the ball mill during rotation. Compared with the traditional ball mill supported only by bearings, it has a better anti-impact and vibration effect, and the service life of the ball mill is longer.

[0065] Embodiment 8

[0066] The automatic blocking mechanism includes blocking plates 204, which are arranged in pairs, and each two blocking plates 204 blocks one inlet and outlet 202. The blocking plates 204 are arc-shaped curved structures, and the curvature of the curvature is the same as the surface curvature of the ball mill 2. The blocking plates 204 are installed on the outer wall of the ball mill 2 through the arc guide rail 5 and the slider 501. When a pair of blocking plates 204 are close to each other, the inlet and outlet 202 can be blocked. When a pair of blocking plates 204 are away from each other, the inlet and outlet 202 can be opened. The blocking plates 204 on the same side of the ball mill 2 are connected and fixed by a connecting piece 205 to ensure synchronous movement. The slider 501 A first arc-shaped transmission rack 502 is also fixed on the ball mill 2, a second transmission rack 503 is fixed on the top of the first arc-shaped transmission rack 502, a second gear 504 is installed on the top of the ball mill 2, and the second transmission racks 503 located on both sides of the ball mill 2 mesh with the second gear 504 from both sides of the second gear 504. A driven transmission shaft 603 and an active driving shaft 6 are respectively provided on both sides of the ball mill 2. The active driving shaft 6 is driven to rotate by the third rotating motor 601, and the active driving shaft 6 and the driven transmission shaft 603 are both fixed with a third gear 602, and the third gear 602 meshes with the first arc-shaped transmission rack 502. If you want to open the material inlet and outlet 202, you only need to turn on the third rotating motor 601. The third rotating motor 601 can drive the active driving shaft 6. When the active driving shaft 6 rotates, the third gear 602 can be engaged with the first arc-shaped transmission rack 502 to drive the blocking plate 204 on the same side to move. At this time, the second transmission rack 503 on the same side will move along, and then the engagement with the second gear 504 can drive the second transmission rack 503 on the other side to move in the opposite direction synchronously, thereby driving the blocking plate 204 on the other side to move in the opposite direction synchronously, thereby achieving the purpose of opening the material inlet and outlet 202. If you want to close the material inlet and outlet 202, 02, it is sufficient to control the third rotating motor 601 to rotate in the opposite direction. It is simple and convenient to use. Compared with the baffle installed in a traditional hinged manner, there is no need to set an additional locking buckle. The locking can be completed by the locking mechanism of the third rotating motor 601. In addition, since the freedom of movement of the sealing plate 204 is limited by the arc guide rail 5, the sealing plate 204 is not easy to loosen when it is subjected to the impact force generated by the ball mill 2. The baffle installed in a transmission hinged manner not only has a large space range when opening and closing, which is easy to interfere with the mounting bracket, but also is easy to loosen when impacted, resulting in a poor seal.
