Description

Technical Field

[0001] The invention relates to the technical field of ceramic drying, in particular to drying equipment and a drying method for ceramic production. Background Art

[0002] Ceramics is a general term for pottery and porcelain. Traditional ceramics, also known as ordinary ceramics, are products made from natural silicates such as clay as the main raw materials. Modern ceramics, also known as new ceramics, fine ceramics or special ceramics, are often made from non-silicate chemical raw materials or artificial synthetic raw materials, such as oxides such as aluminum oxide, zirconium oxide, titanium oxide, etc. and non-oxides such as silicon nitride and boron carbide.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0045] See also Figures 1 to 17The ceramic production drying equipment of the present invention comprises a main drying box 100, a feeding sealing door 101, a discharging sealing door 102, an active rotating wheel 103, an active driving motor 104, a first driven wheel 105, a second driven wheel 106, a third driven wheel 107, a driving chain 108, a plurality of connecting parts 109, a plurality of drying tray parts 200, a plurality of drying rotating mechanisms 300, a supporting frame 110, a main hot air blower 120, a first auxiliary drying mechanism 400 and at least one second auxiliary drying mechanism 600; the feeding sealing door 101 is installed on one side of the main drying box 100, the discharging sealing door 102 is installed on the other side of the main drying box 100, the active rotating wheel 103 is rotatably connected to the lower side of the inside of the main drying box 100, the first driven wheel 105 is rotatably connected to the lower side of the inside of the main drying box 100, and the second driven wheel 106 is installed on the main drying box 1 00, the third driven wheel 107 is rotatably connected to the upper side of the main drying box 100, the active driving motor 104 is installed on the outside of the main drying box 100, and the output end of the active driving motor 104 is connected to the active rotating wheel 103, the driving chain 108 is installed between the active rotating wheel 103, the first driven wheel 105, the second driven wheel 106 and the third driven wheel 107, a plurality of connecting parts 109 are installed at equal intervals on one side of the driving chain 108, the drying tray part 200 is installed on the connecting part 109, the drying rotating mechanism 300 is installed in the drying tray part 200, the support frame 110 is installed at the center of the main drying box 100, and the main hot air blower 120 is installed on the lower side of the support frame 110, the first auxiliary drying mechanism 400 is installed on the upper side of the support frame 110, and the second auxiliary drying mechanism 600 is installed on the upper side of the main drying box 100;

[0046] Among them, the main drying box 100 plays a role of fixed support for each structure in the drying equipment for ceramic production of the present invention. The feed sealing door 101 and the discharge sealing door 102 can be rotatably connected to both sides of the main drying box 100. When all the ceramics to be dried are placed in the main drying box 100, the feed sealing door 101 and the discharge sealing door 102 can be closed to improve the sealing inside the main drying box 100, thereby ensuring the drying effect of the ceramics;

[0047] Further, when the user needs to use the drying device for ceramic production of the present invention to dry ceramics, first, the active drive motor 104 enters the working state, so that the output end of the active drive motor 104 drives the active rotating wheel 103 to rotate, and then the active rotating wheel 103 drives the driving chain 108 to rotate between the active rotating wheel 103, the first driven wheel 105, the second driven wheel 106 and the third driven wheel 107, so that the driving chain 108 drives the multiple connecting parts 109 to move together, and then the connecting part 109 drives the drying tray part 200 to move together;

[0048] Furthermore, the active rotating wheel 103, the first driven wheel 105, the second driven wheel 106 and the third driven wheel 107 may be arranged in a rectangular shape, so that the driving chain 108 drives the plurality of drying trays 200 to move in the main drying box 100, and at the same time, the active driving motor 104 drives the driving chain 108 to rotate in a counterclockwise direction;

[0049] Specifically, when ceramics need to enter the main drying box 100, the ceramics enter the drying tray part 200 directly through the external conveyor belt or the external manipulator through the feed sealing door 101. At this time, the active drive motor 104 stops working until all the drying tray parts 200 have ceramics to be dried. Then, the feed sealing door 101 is closed. Then, each drying tray part 200 is provided with a drying rotating mechanism 300, and the drying rotating mechanism 300 drives the ceramics to rotate intermittently, thereby ensuring the main hot air blower 120 to dry the ceramics uniformly;

[0050] More specifically, the outlet direction of the main hot air blower 120 is fixed, so as to achieve the pre-drying action of the ceramics, and the drying rotating mechanism 300 drives the ceramics to rotate intermittently, thereby ensuring that the ceramics can be pre-dried more evenly;

[0051] When the ceramics rotate one circle in the main drying box 100 along with the drying tray 200, the pre-drying of the ceramics is completed. This process can prevent the ceramics from being cracked due to a sudden increase in the drying temperature.

[0052] Further, after the pre-drying action is completed, the ceramic moves with the drying tray part 200 until it passes through the second auxiliary drying mechanism 600. The second auxiliary drying mechanism 600 dries the outer surface of the ceramic from bottom to top to avoid the ceramic surface being unable to fully dry the pattern or groove due to the presence of structures such as patterns or grooves, thereby causing uneven drying of the ceramic surface. At the same time, the second auxiliary drying mechanism 600 can also dry the inside of the ceramic, thereby ensuring the drying efficiency and uniformity of the ceramic. Of course, when the second auxiliary drying mechanism 600 performs the first fine drying action on the ceramic, the active drive motor 104 can stop working, that is, the active drive motor 104 can control its working state according to the actual drying process;

[0053] Furthermore, after the second auxiliary drying mechanism 600 completes the first fine drying action on the ceramic, when the ceramic passes through the first auxiliary drying mechanism 400, the first auxiliary drying mechanism 400 performs a second fine drying action on the ceramic, so that the lower side of the outer surface of the ceramic is also dried, thereby completing the omnidirectional drying action on the ceramic, and improving the drying efficiency and effect of the ceramic;

[0054] After the second fine drying operation is completed, the discharge sealing door 102 is in an open state, and then the ceramics are transferred from the drying tray portion 200 to the external environment by external manipulators and other handling equipment.

[0055] In this embodiment, the drying tray part 200 includes a tray connection block 201, a tray rotating part 202, a tray connection rod 203, a tray limiting wheel 204 and a tray part 205. The tray connection block 201 is installed on the connecting part 109, the tray rotating part 202 is rotatably connected in the tray connection block 201, the tray connection rod 203 is installed on the side of the tray connection block 201 away from the connecting part 109, the tray limiting wheel 204 is rotatably connected to the end of the tray connection rod 203, and the tray part 205 is rotatably connected to one end of the tray rotating part 202 extending out of the tray connection block 201;

[0056] The tray connection block 201 plays a role of fixed support for each structure in the drying tray part 200, and the tray part 205 is rotatably connected to the tray rotating part 202. Therefore, when the tray part 205 moves with the driving chain 108, the tray part 205 is always in a vertical downward state to achieve the support effect on the ceramics;

[0057] A transverse limiting track 206 and a longitudinal limiting track 207 are installed in the main drying box 100 for limiting the rotation of the tray limiting wheel 204, and the transverse limiting track 206 and the longitudinal limiting track 207 are arranged perpendicular to each other;

[0058] When the tray connection block 201 moves with the driving chain 108, the tray limiting wheel 204 can move in the transverse limiting track 206 and the longitudinal limiting track 207, thereby ensuring the stability of the movement of the tray connection block 201, and then ensuring the stability of the movement of the tray part 205, thereby achieving a stable transportation action for ceramics;

[0059] Furthermore, there are two transverse limiting rails 206 and two longitudinal limiting rails 207, and the two transverse limiting rails 206 are located on the upper and lower sides of the driving chain 108, and the two longitudinal limiting rails 207 are located on the left and right sides of the driving chain 108, thereby realizing all-round limiting action on the drying tray part 200 during the transportation process.

[0060] In this embodiment, the drying rotation mechanism 300 includes a drying rotation motor, a drying rotation active rod 320, a drying rotation active wheel 330, a drying rotation driven wheel 340, a drying rotation driven rod 350 and a drying rotation disk 360. The drying rotation active rod 320 is rotatably connected to the tray portion 205. The drying rotation motor is installed on the lower side of the tray portion 205, and the output end of the drying rotation motor is connected to the drying rotation active rod 320. The drying rotation active wheel 330 is installed on the drying rotation active rod 320. The drying rotation driven rod 350 is rotatably connected to the drying rotation active rod 320. On one side, the drying rotating driven wheel 340 is connected to the drying rotating driven wheel 340, and the drying rotating driven wheel 340 abuts against the drying rotating driving wheel 330, and the drying rotating disk 360 is installed on the upper end of the drying rotating driven rod 350; the drying rotating driving wheel 330 is provided with a first meshing portion 331, and the drying rotating driven wheel 340 is provided with a plurality of second meshing portions 341, and the first meshing portion 331 and the second meshing portion 341 are adapted to each other; the drying rotating disk 360 is provided with a ceramic placement area 361, and a plurality of heat flow holes 362 are provided in the ceramic placement area 361;

[0061] Among them, when the ceramics to be dried enter the main drying box 100, first, the ceramics are placed on the drying rotating disk 360, and when the driving chain 108 drives the overall drying tray part 200 to transfer, the drying rotating motor enters the working state, so that the output end of the drying rotating motor drives the drying rotating active rod 320 to rotate, and then the drying rotating active rod 320 drives the drying rotating active wheel 330 to rotate, so that the drying rotating active wheel 330 can intermittently drive the drying rotating driven wheel 340 to rotate, so that the drying rotating driven wheel 340 drives the drying rotating driven rod 350 to rotate, and then the drying rotating driven rod 350 drives the drying rotating disk 360 to rotate intermittently, thereby ensuring that the ceramics can be evenly dried by the main hot air blower 120;

[0062] It is worth noting that the intermittent movement of the drying rotating disk 360 can ensure that after the ceramic is dried on one side facing the main hot air blower 120, the drying rotating disk 360 rotates a certain angle to dry the other side of the ceramic, thereby ensuring the uniformity of the ceramic drying;

[0063] It is worth noting that when the drying rotation driving wheel 330 rotates one circle, the first meshing portion 331 meshes with the second meshing portion 341 only once, so that when the first meshing portion 331 meshes with any part of the second meshing portion 341, the drying rotation driving wheel 330 drives the drying rotation driven wheel 340 to rotate. Since there is only a part of the first meshing portion 331 on the drying rotation driving wheel 330, the drying rotation driving wheel 330 drives the drying rotation driven wheel 340 to rotate intermittently, so that the drying rotation driven wheel 340 drives the drying rotation driven rod 350 to rotate, and then the drying rotation driven rod 350 drives the drying rotation disk 360 to rotate intermittently.

[0064] Furthermore, the bottom of the ceramic is placed on the ceramic placement area 361. Since a plurality of heat circulation holes 362 are provided on the ceramic placement area 361, the hot air blown by the main hot air blower 120 can be blown toward the bottom of the ceramic through the plurality of heat circulation holes 362, thereby being able to dry the bottom of the ceramic to a certain extent, thereby ensuring a comprehensive drying action on the ceramic.
