Description

Technical Field

[0001] The present invention relates to the technical field of production equipment for heat-resistant ceramic products, and particularly to a ceramic dryer for heat-resistant ceramic production. Background Art

[0002] Heat-resistant ceramics are materials that can withstand high temperatures and have good heat conduction or heat insulation properties, and are widely used in multiple fields, including industry, construction, transportation, and daily life, etc.

[0003] In the process of making tiles from heat-resistant ceramics, the drying process is crucial. Since the tile blank contains a large amount of moisture after being formed, if it is not dried sufficiently, the rapid vaporization of moisture during firing will cause defects such as cracking and deformation of the tiles, seriously affecting the product quality and the finished product rate; therefore, drying is a key link to ensure the quality of heat-resistant ceramic tiles.

[0004] Currently, when drying tile blanks, it is mostly done by placing the tile blanks on a roller conveyor belt and setting a drying source below the roller conveyor belt for drying. This method has significant drawbacks: in terms of drying efficiency, relying only on a single heat source below the roller conveyor belt, the heat transfer path is limited, the moisture evaporation is slow, and it is difficult to meet the needs of large-scale production; at the same time, during the conveying process of the tile blank, heat is only transferred from the bottom, and the heat obtained on the upper surface and the side surfaces is insufficient, resulting in a single drying surface and uneven drying, affecting the overall performance and appearance quality of the tile blank. Summary of the Invention

[0005] Based on this, it is necessary to provide a ceramic dryer for heat-resistant ceramic production in view of the problem of low drying efficiency existing in the current drying process of heat-resistant ceramic tile blanks.

[0038] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.

[0039] As Figures 1 to 10 As shown, a ceramic dryer for hot ceramic production provided by an embodiment of the present invention is used for drying tile blanks, and is configured to include a horizontally arranged drying pipe 1, a heat source, a plurality of jigs 5, a moving mechanism 6 and a transmission mechanism 7. At least two rotating rings 2 are coaxially embedded on the inner peripheral wall of the drying pipe 1, and all the rotating rings 2 are arranged at intervals along the axis direction of the drying pipe 1. Four guide rails 3 are jointly arranged on the inner peripheral walls of the drying pipe 1 and the rotating rings 2. The four guide rails 3 are arranged at equal intervals in the circumferential direction, and the guide rails 3 extend in a direction parallel to the axis direction of the drying pipe 1. The plane formed by two relatively arranged guide rails 3 on the drying pipe 1 is parallel to the horizontal plane or parallel to the vertical plane; the heat source is configured to be able to heat air and then convey it into the drying pipe 1; the jig 5 is configured to be able to clamp the tile blank and be able to move along two relatively arranged guide rails 3 at the same time; a plurality of jigs 5 are arranged along the axis direction of the drying pipe 1 during drying; the rotating ring 2 can rotate around its own axis so as to drive the jig 5 thereon to rotate during drying, so that adjacent jigs 5 are vertically arranged, thereby changing the air flow path; the moving mechanism 6 is configured to be able to provide the driving force for the movement of the jig 5; the transmission mechanism 7 is configured to be able to provide the driving force for the rotation of the rotating ring 2.

[0040] Specifically in this embodiment, for the convenience of installing the drying pipe 1, the ceramic dryer for hot ceramic production is further provided with a frame 16. When installed, the drying pipe 1 is fixed on the frame 16 and extends horizontally in the front-rear direction. The number of rotating rings 2 is set to two, which are respectively located at both ends of the drying pipe 1. The fixture 5 is of a cubic structure. Taking the case where the fixture 5 is placed horizontally as an example, a ventilation hole 501 is penetrated through the top of the fixture 5. The ventilation hole 501 is square, and the sides of the ventilation hole 501 are parallel to the sides of the fixture 5, ensuring that the contact area with hot air can be increased. An installation hole 502 is penetrated through the middle position on the rear side wall of the fixture 5. The installation hole 502 is square, and the sides of the installation hole 502 are parallel to the sides of the fixture 5. The side length of the installation hole 502 in the left-right direction is greater than the side length of the ventilation hole 501 in the left-right direction, so that a stepped structure can be formed at the connection position of the ventilation hole 501 and the installation hole 502 in the vertical direction, ensuring that the ceramic tile blank can be placed.

[0041] The cross-sectional shape of the guide rail 3 is T-shaped, and the horizontal section faces inward. For the convenience of forming a sliding fit with the guide rail 3, first sliding grooves are provided on the left and right side walls of the fixture 5. The first sliding grooves extend in the horizontal direction and the cross-sectional shape is T-shaped. When installed, the fixture 5 is sleeved on the guide rail 3 through the first sliding grooves, ensuring that it can slide along the guide rail 3.

[0042] Furthermore, the heat source is a heating type blower 401, which generally includes a blower, a heater (electric heating wire) and a control circuit. The air outlet of the blower is communicated with the drying pipe 1 through a pipeline. Ensure that when the blower is powered on, cold air is inhaled by the blower, the cold air is heated into hot air by the heater, and the hot air then discharges from the air outlet and is transported into the drying pipe 1 through the pipeline to dry the ceramic tile blank.

[0043] During the use process, first place the ceramic tile blank in the fixture 5, and stably clamp the ceramic tile blank by using the stepped structure formed by the installation hole 502 and the ventilation hole 501 on the fixture 5; then, put the fixture 5 into the drying pipe 1 from the front end of the drying pipe 1, so that the fixture 5 forms a sliding fit with two guide rails 3 whose planes formed by the first sliding grooves and the drying pipe 1 are parallel to the horizontal plane; then, the driving force is provided by the moving mechanism 6 to drive the fixture 5 to move along the guide rail 3 into the drying pipe 1. After the first fixture 5 is placed, repeat the above operation, arrange multiple fixtures 5 in sequence along the axis direction of the drying pipe 1, so that the ceramic tile blanks enter the drying pipe 1 orderly.

[0044] During the movement of the fixture 5, the driving force is provided by the transmission mechanism 7 to drive the rotating ring 2 at the front end of the drying pipe 1 to rotate, and then drive the fixture 5 at the even positions to rotate, so that the adjacent fixtures 5 are vertically arranged; then the heating blower 401 is started, and the heating blower 401 heats the cold air and conveys it into the drying pipe 1 through the pipeline; when the hot air enters the drying pipe 1, due to the flow characteristics, the initial distribution is not uniform, and the fixtures 5 arranged vertically and horizontally in the drying pipe 1 play a role in forced diversion of the hot air: the hot air is first divided into a first stream and a second stream by the horizontally arranged fixture 5, and these two streams of hot air continue to move forward and are respectively divided again by the subsequent vertically arranged fixtures 5 to form a third stream, a fourth stream, a fifth stream and a sixth stream. Subsequently, the third stream and the fifth stream, and the fourth stream and the sixth stream of hot air are fused with each other, and this process of division and fusion continues to cycle in the drying pipe 1.

[0045] In the above process, the hot air is continuously divided and recombined by the fixture 5 to form a turbulent flow state. This turbulent flow effectively breaks the thermal boundary layer on the surface of the ceramic tile blank. The thermal boundary layer is a relatively stable air layer formed on the surface of the ceramic tile due to heat transfer, which will hinder the further transfer of heat. When the thermal boundary layer is broken, the heat exchange efficiency between the hot air and the surface of the ceramic tile blank is greatly improved, and the heat can be transferred to the inside of the ceramic tile blank more quickly and evenly, accelerating the evaporation of moisture and significantly improving the drying efficiency; at the same time, the continuous diversion and fusion of the hot air enable the ceramic tile blanks in different regions of the drying pipe 1 to obtain similar heat supply, effectively avoiding the problems of local overheating or insufficient drying, and realizing the uniform drying of the ceramic tile blanks.

[0046] When the fixture 5 at the even positions moves to the rotating ring 2 at the rear end of the drying pipe 1, the driving force is provided by the transmission mechanism 7 to drive the rotating ring 2 at the rear end of the drying pipe 1 to rotate, and then drive the fixture 5 at the even positions to rotate, so that the adjacent fixtures 5 are at the same vertical height, enabling all the fixtures 5 to be removed from the drying pipe 1 in a unified posture, which is convenient for carrying out the next process.

[0047] In some other embodiments, to improve the production line of the ceramic dryer for hot ceramic production, it is provided that the ceramic dryer for hot ceramic production further includes a first conveying mechanism 10, a second conveying mechanism 11, a third conveying mechanism 12, a fourth conveying mechanism 13 and a taking mechanism. The first conveying mechanism 10 is arranged below the drying pipe 1 and is configured to be able to convey the fixture 5 from the rear to the front; the second conveying mechanism 11 is arranged on the front side of the drying pipe 1 and is configured to be able to convey the fixture 5 from the front to the rear to the drying pipe 1; the third conveying mechanism 12 is arranged on the front side of the second conveying mechanism 11 and can move in the vertical direction, and is configured to be able to receive the fixture 5 conveyed by the first conveying mechanism 10 and convey the fixture 5 to the second conveying mechanism 11; the fourth conveying mechanism 13 is arranged on the rear side of the drying pipe 1 and is configured to be able to receive the fixture 5 removed from the drying pipe 1 and convey the fixture 5 from the front to the rear to the taking mechanism; the taking mechanism is configured to be able to take the fixture 5 from the fourth conveying mechanism 13.

[0048] Specifically in this embodiment, the first conveying mechanism 10, the second conveying mechanism 11, the third conveying mechanism 12 and the fourth conveying mechanism 13 are all provided to include a plurality of conveying rollers 15. The conveying rollers 15 are horizontally arranged and extend in a direction perpendicular to the axis of the drying pipe 1. The plurality of conveying rollers 15 are arranged at equal intervals in a direction parallel to the axis of the drying pipe 1. The conveying rollers 15 of the first conveying mechanism 10, the second conveying mechanism 11 and the fourth conveying mechanism 13 are all arranged on the frame 16 during installation. To facilitate the installation of the conveying rollers 15 of the third conveying mechanism 12, the ceramic dryer for hot ceramic production is provided to further include a machine base 17. The machine base 17 is located on the front side of the first conveying mechanism 10, and the conveying rollers 15 of the third conveying mechanism 12 are arranged on the machine base 17 during installation.

[0049] To facilitate providing the driving force for the rotation of the conveying roller 15, taking the first conveying mechanism 10 as an example, the first conveying mechanism 10 is provided to further include a sprocket, an endless chain and a third driving motor. A sprocket is fixedly sleeved on the conveying roller 15 at the rearmost side, and two sprockets are fixedly sleeved on each of the other conveying rollers 15; an endless chain is drivingly sleeved between the sprockets on the adjacent conveying rollers 15; the third driving motor is installed on the frame 16, and a sprocket is fixedly sleeved on the motor shaft of the third driving motor, and an endless chain is drivingly sleeved between this sprocket and one of the sprockets on the foremost conveying roller 15.

[0050] To facilitate providing the driving force for the third conveying mechanism 12 to move in the vertical direction, the ceramic dryer for hot ceramic production is provided to further include a first driving cylinder. The first driving cylinder is installed on the frame 16, and the conveying shaft of the first driving cylinder is arranged vertically upward and is fixed on the machine base 17 to ensure that it can drive the third conveying mechanism 12 to move in the vertical direction.

[0051] Optionally, the first driving cylinder can be set as any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0052] Further, the picking mechanism is set to include a robotic arm 1401, and the robotic arm 1401 is located on the right side of the fourth conveying mechanism 13 during installation.

[0053] Initially, the conveying rollers 15 of the third conveying mechanism 12 and the conveying rollers 15 of the first conveying mechanism 10 are at the same vertical height.

[0054] During use, first start the third driving motor. The third driving motor drives the conveying roller 15 to rotate through a sprocket and an endless chain. During the rotation of the conveying roller 15, the empty fixture 5 is first conveyed from the back to the front by the first conveying mechanism 10 to the third conveying mechanism 12, and then conveyed from the back to the front by the third conveying mechanism 12 to a preset position to load the ceramic blank. The fixture 5 loaded with the ceramic blank is then conveyed from the front to the back by the third conveying mechanism 12 to a position close to the second conveying mechanism 11. Then start the first driving cylinder, and the first driving cylinder synchronously drives the third conveying mechanism 12 to move upward to the same vertical height as the second conveying mechanism 11. Then the fixture 5 loaded with the ceramic blank is conveyed from the front to the back by the third conveying mechanism 12 to the second conveying mechanism 11. Then the fixture 5 loaded with the ceramic blank is conveyed by the second conveying mechanism 11 to the drying tube 1 for drying. The fixture 5 loaded with the dried ceramic blank is received by the fourth conveying mechanism 13 and conveyed from the front to the back to the robotic arm 1401. The robotic arm 1401 picks up the fixture 5 loaded with the dried ceramic blank from the fourth conveying mechanism 13 to a preset position for the next process.

[0055] In a further embodiment, to ensure the processing continuity of the ceramic tile blank, a blocking plate 8 can be provided at the rear end of the drying tube 1. The axis of the blocking plate 8 extends in the horizontal direction. The blocking plate 8 can slide in the vertical direction and is configured to be able to open or block the rear opening of the drying tube 1. An elastic member is provided on one side of each fixture 5 close to the blocking plate 8, and the elastic member can form a stop fit with the blocking plate 8 or the rear fixture 5.

[0056] Specifically in this embodiment, to facilitate the installation of the plugging disc 8, a first notch 101 is provided on the circumferential side wall at the rear end of the drying pipe 1, and a second sliding groove 102 is provided on the inner circumferential wall at the rear end of the drying pipe 1 corresponding to the first notch 101. The second sliding groove 102 is of an arc structure and has an upward opening. When installing, the plugging disc 8 is slidably inserted into the second sliding groove 102; at the position corresponding to the first notch 101 at the top of the rear end of the drying pipe 1, eight limiting strips 103 are provided. The limiting strips 103 extend in the vertical direction. The eight limiting strips 103 are evenly divided into two large groups, and the two large groups are arranged at intervals in the left-right direction. Each large group is divided into two small groups. The two small groups in the same large group are arranged at intervals in the direction parallel to the axis of the drying pipe 1, and a third sliding groove is formed therebetween. The third sliding groove communicates with the second sliding groove 102. When installing, the plugging disc 8 is slidably inserted into the third sliding groove. The two limiting strips 103 in the same small group are arranged at intervals in the left-right direction, and a fourth sliding groove is formed therebetween. Four guide posts are respectively provided on the front and rear disc surfaces of the plugging disc 8, and the guide posts are slidably inserted into the fourth sliding groove to ensure that the plugging disc 8 can only move in the vertical direction.

[0057] To facilitate providing a driving force for the plugging disc 8 to slide in the vertical direction, the ceramic dryer for thermal ceramic production is further provided with a second driving cylinder. The second driving cylinder is installed on the frame 16, the conveying shaft of the second driving cylinder is arranged vertically downward, and is fixed on the circumferential side wall at the top of the plugging disc 8 to ensure that the plugging disc 8 can be driven to move in the vertical direction.

[0058] Optionally, the second driving cylinder can be any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0059] Further, the elastic member is a compression spring, and extends horizontally in the front-rear direction and is fixedly arranged on the rear side wall of the fixture 5.

[0060] Taking the example that six fixtures 5 can be accommodated in the drying pipe 1, the number of the rotating rings 2 is set to three and are arranged at equal intervals along the axis of the drying pipe 1.

[0061] Initially, the plugging disc 8 is in the position of plugging the rear end opening of the drying pipe 1.

[0062] During the use process, the first fixture 5 is conveyed to the front end of the drying pipe 1 by the second conveying mechanism 11. Subsequently, the first fixture 5 forms a sliding fit with two guide rails 3 on the drying pipe 1 whose plane formed by the first sliding groove and the drying pipe 1 is parallel to the horizontal plane; then, the driving force is provided by the moving mechanism 6 to drive the first fixture 5 to move into the drying pipe 1 along the guide rail 3. After the first fixture 5 is placed, the above operation is repeated to arrange the remaining five fixtures 5 in sequence along the axis direction of the drying pipe 1, so that the ceramic tile blanks enter the drying pipe 1 orderly.

[0063] During the movement of the fixture 5, when the second, fourth, and sixth fixtures 5 pass by the rotating ring 2 located at the foremost side, the driving mechanism 7 provides a driving force to drive the rotating ring 2 located at the foremost side to rotate, thereby driving the second, fourth, and sixth fixtures 5 to rotate, so that adjacent fixtures 5 are vertically arranged.

[0064] When the first fixture 5 moves until the spring 9 on it abuts against the plugging disc 8, as the first fixture 5 continues to move, the spring 9 on it is compressed. The setting of the spring 9 can prevent the ceramic tile blank held by the first fixture 5 from being displaced due to a sudden collision between the first fixture 5 and the plugging disc 8, avoiding damage to the structure of the ceramic tile blank and further causing an increase in the rejection rate, until the first fixture 5 remains stationary; when the second fixture 5 moves until the spring 9 on it abuts against the first fixture 5, as the second fixture 5 continues to move, the spring 9 on it is compressed. The setting of the spring 9 can prevent the ceramic tile blank held by the second fixture 5 from being displaced due to a sudden collision between the second fixture 5 and the first fixture 5, avoiding damage to the structure of the ceramic tile blank and further causing an increase in the rejection rate, until the second fixture 5 remains stationary, and so on, until all six fixtures 5 remain stationary.

[0065] Meanwhile, the heating blower 401 is started, and the heating blower 401 heats the cold air and conveys it into the drying pipe 1 through a pipeline to dry the ceramic tile blank.

[0066] After drying is completed, first, the driving mechanism 7 provides a driving force to drive all the rotating rings 2 to rotate, thereby driving the second, fourth, and sixth fixtures 5 to rotate, so that adjacent fixtures 5 are at the same vertical height; then the second driving cylinder is started, and the second driving cylinder drives the plugging disc 8 to move upward to open the rear end opening of the drying pipe 1. At this time, the spring 9 on the first fixture 5 can be released backward because the obstruction is removed. The spring 9 on the first fixture 5 can be released backward because the obstruction is removed, and drives the first fixture 5 to accelerate backward, so that there is a certain distance between the first fixture 5 and the second fixture 5, and so on, so that all fixtures 5 are spaced apart. Then the moving mechanism 6 provides a driving force to drive the fixture 5 to move backward along the guide rail 3.

[0067] The fixture 5 is then received by the fourth conveying mechanism 13 and conveyed from front to back to the robotic arm 1401. Since the fixtures 5 are spaced apart, the robotic arm 1401 can successively pick up the fixtures 5 from the fourth conveying mechanism 13 to a preset position, avoiding the waiting time of subsequent fixtures 5 and affecting the continuity of processing.

[0068] In a further embodiment, the plugging disc 8 is provided with ventilation holes 801, and the ventilation holes 801 are communicated with the air outlet of the heat source.

[0069] Specifically in this embodiment, the vent hole 801 is arranged in the middle of the disk surface of the plugging disk 8 and is communicated with the air outlet of the heating blower 401 through a pipeline, ensuring that during use, hot air can always move axially along the drying tube 1 from the middle to the front, guaranteeing the drying efficiency.

[0070] In other embodiments, to ensure the processing continuity of the ceramic tile blanks, the number of the robotic arms 1401 can also be set to two, which are respectively located on the left and right sides of the fourth conveying mechanism 13. Thus, by alternately picking up the fixture 5 containing the dried ceramic blank by the two robotic arms 1401, the problem that a single robotic arm 1401 takes a certain amount of time to pick up the fixture 5 containing the dried ceramic blank, resulting in a waiting time for the subsequent fixture 5 and affecting the processing continuity, can be avoided.

[0071] In some other embodiments, the moving mechanism 6 is set to include rollers 601 and a first driving motor 602. At least one pair of rollers 601 is inserted into each fixture 5, and the rollers 601 of the same pair can respectively form a rolling fit with two relatively arranged guide rails 3; a first driving motor 602 is arranged on each fixture 5, the first driving motor 602 is electrically connected to the guide rail 3, and the motor shaft of the first driving motor 602 is fixedly and coaxially inserted into one of the rollers 601.

[0072] Specifically in this embodiment, taking the case where the fixture 5 is horizontally arranged as an example, the axis of the roller 601 extends in the vertical direction, and the roller 601 forms a rolling fit with the inner side wall of the large end of the guide rail 3; the first driving motor 602 is located at the top of the fixture 5 during installation, and the motor shaft is arranged vertically downward and penetrates through the fixture 5 to ensure that it can be fixedly and coaxially inserted into the roller 601; to facilitate the electrical connection between the first driving motor 602 and the guide rail 3, a sliding contact wire is laid on the guide rail 3, and a conductive sheet is arranged on the first driving motor 602. The conductive sheet can contact the sliding contact wire and form an electrical connection, so as to transmit current to the first driving motor 602, and then the fixture 5 can be driven to move on the guide rail 3 through the roller 601.

[0073] In some other embodiments, the transmission mechanism 7 is set to include tooth protrusions 701 and a second driving motor 702. A plurality of tooth protrusions 701 are arranged on the outer peripheral wall of each rotating ring 2. The tooth protrusions 701 are strip-shaped structures and extend in a direction parallel to the axis direction of the rotating ring 2. The plurality of tooth protrusions 701 on the same rotating ring 2 are arranged at equal intervals in the circumferential direction; second driving motors 702 are arranged at positions corresponding to each rotating ring 2 on the drying tube 1, and a gear 703 is fixedly sleeved on the motor shaft of each second driving motor 702, and the gear 703 meshes with the tooth protrusion 701.

[0074] Specifically in this embodiment, the second driving motor 702 is installed at the bottom of the drying tube 1, and the motor shaft extends in the horizontal direction; a second notch is formed at the bottom of the drying tube 1 to ensure that the tooth convex 701 can be exposed, so as to ensure that the tooth convex 701 can mesh with the gear 703.

[0075] During use, the second driving motor 702 is started, and the second driving motor 702 drives the rotating ring 2 to rotate through the meshing between the gear 703 and the tooth convex 701.

[0076] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0077] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
