Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramic products technology, and in particular to a rapid drying device for ceramic product green bodies. Background Technology
[0002] Before firing, ceramic products require drying to remove moisture from the green blanks. Uneven drying or improper drying rate can easily lead to cracking and deformation of the green blanks, directly affecting the yield and product quality. Traditional drying equipment often uses static spreading or fixed support racks to place the green blanks, with the position and orientation of the green blanks relatively fixed during the drying process.
[0003] This makes it difficult for hot air to evenly cover all surfaces of the green body, especially for green bodies with complex structures or uneven thickness. Their leeward side, crevices, and bottom tend to dry slowly, while the windward side may dry too quickly, thus creating a humidity gradient and stress inside and outside the green body, increasing the risk of breakage. To address this, a rapid drying device for ceramic green bodies is proposed. Utility Model Content
[0004] Therefore, it is necessary to provide a rapid drying device for ceramic green bodies to address the aforementioned technical problems. This device, by incorporating a rotatable support frame and an independently driveable tray on the support frame, allows the ceramic green body placed on the tray to simultaneously undergo two movements: first, it revolves around the central axis of the support frame, changing its macroscopic position within the drying chamber; second, the tray rotates intermittently via a linkage unit. This combined motion significantly increases the contact area and angle between the green body and the hot air, eliminating the airflow dead zones inherent in fixed drying methods. This ensures uniform heating of all surfaces of the green body and simultaneous moisture loss, effectively preventing deformation and cracking caused by uneven drying, and greatly improving drying quality and yield.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A rapid drying device for ceramic green bodies includes a drying oven with a partition plate inside, which divides the interior of the drying oven into multiple adjacent drying chambers. Each drying chamber is equipped with a support unit for supporting the ceramic green bodies. A drying fan is located on the top of the drying oven. The support unit includes a pull-out plate slidably disposed on the bottom wall of the drying oven. A support plate is fixed to the top of the pull-out plate. A rotating component is installed at the center of the top of the support plate. A support frame is installed on the surface of the rotating component. A tray is movably mounted at each end of the support frame. A toothed ring is fixed to the outer side of the tray.
[0007] The support plate is also provided with a linkage unit for driving the support tray;
[0008] The support frame includes a first support frame and a second support frame. The first support frame and the second support frame are arranged in an alternating manner in the height direction of the rotating rod, and the support tray on the first support frame corresponds to the gap between two adjacent support trays on the second support frame in the height direction.
[0009] The linkage unit includes a first linkage unit corresponding to the height of the first support frame and a second linkage unit corresponding to the height of the second support frame, and a drive unit is jointly assembled between the first linkage unit and the second linkage unit.
[0010] Furthermore, the rotating component includes a rotary motor fixed at the top center of the support plate and a rotating rod connected to the output shaft of the rotary motor, and the support frame is fixed to the surface of the rotating rod.
[0011] Furthermore, the first linkage unit includes a double-sided toothed ring that is commonly sleeved on the outer side of the toothed rings on multiple first support frames. A drive gear is fixed to the double-sided toothed ring at the toothed ring on the first support frame. Intermittent meshing portions are evenly distributed on the inner side of the double-sided toothed ring. The double-sided toothed ring meshes with the toothed ring through the intermittent meshing portions, and the drive gear meshes with the double-sided toothed ring.
[0012] The bottom of the double-sided toothed ring is movably connected to a support ring, and the bottom of the support ring is fixed with a support member corresponding to the drive gear.
[0013] Furthermore, the first linkage unit and the second linkage unit have the same structure.
[0014] Furthermore, the drive unit includes a first inner support rod and a second inner support rod, and there are multiple first inner support rods and second inner support rods. Each first inner support rod passes through a support member in the first linkage unit in its height direction and is fixed to the drive gear therein. The support member is movably connected to the first inner support rod.
[0015] Each of the second inner support rods passes through the support member in the second linkage unit in its height direction and is fixed to the drive gear. The support member in the second linkage unit is movably connected to the second inner support rod.
[0016] Furthermore, the bottom ends of the first inner support rod and the second inner support rod are movably connected to the surface of the bearing plate. The bottom of the first inner support rod and the second inner support rod are both fixed with a lower gear. The inner sides of the multiple lower gears are engaged with an internal gear ring. The inner side of the internal gear ring is engaged with an internal gear. The bottom of the internal gear is connected to a motor fixed to the bearing plate.
[0017] Furthermore, the drive unit also includes a first outer support rod and a second outer support rod, which are respectively disposed on one side of the corresponding first inner support rod and the second inner support rod and fixed to the bearing plate.
[0018] Furthermore, the first outer support rod is fixed to the support member in the first linkage unit corresponding to its height direction, and the second outer support rod is fixed to the support member in the second linkage unit corresponding to its height direction.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] This invention provides a rapid drying device for ceramic green bodies. By incorporating a rotatable support frame and an independently driveable tray on the support frame, the ceramic green body placed on the tray can simultaneously undergo two movements: first, it revolves around the central axis of the support frame, changing its macroscopic position within the drying chamber; second, driven by a linkage unit, the tray intermittently rotates. This combined movement significantly increases the contact area and angle between the green body and the hot air, breaking the airflow dead zones inherent in fixed drying methods. This ensures uniform heating of all surfaces of the green body and simultaneous moisture loss, effectively preventing deformation and cracking caused by uneven drying, and greatly improving drying quality and yield.
[0021] Meanwhile, through the action of the linkage unit, it can independently achieve rotation without changing the macroscopic position of the tray, and has multiple driving modes, thus effectively addressing different drying scenarios for ceramic greenware.
[0022] By designing the support frame as a first support frame and a second support frame, and arranging them alternately in the vertical direction, the gaps between the upper tray and the adjacent lower tray correspond. This staggered layout provides more and smoother channels for the vertical flow and interpenetration of hot air when the trays rotate, optimizing the airflow organization inside the drying chamber, avoiding airflow short-circuiting, improving heat exchange efficiency and the utilization rate of the entire drying space, thereby accelerating the overall drying speed.

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0040] Example 1
[0041] Please refer to Figures 1-7 As shown, a rapid drying device for ceramic green bodies includes a drying chamber 1. The interior of the drying chamber 1 has a partition plate 11, which divides the interior of the drying chamber 1 into multiple adjacent drying chambers 12. Each drying chamber 12 is equipped with a support unit for supporting the ceramic green bodies. The top of the drying chamber 1 has a drying fan 13. The support unit includes a pull-out plate 2 that is slidably disposed on the bottom wall of the drying chamber 1. The pull-out plate 2 can be partially pulled out of the drying chamber 1 for easy removal of the ceramic green bodies. A support plate 21 is fixed to the top of the pull-out plate 2. A rotating component 22 is installed at the center of the top of the support plate 21. A support frame is installed on the surface of the rotating component 22. A support tray 24 is movably assembled at the ends of the support frame. A toothed ring 23 is fixed to the outer side of the support tray 24. The support plate 21 is also equipped with a linkage unit for driving the support tray 24.
[0042] The rotating component 22 includes a rotary motor 220 fixed at the top center of the bearing plate 21 and a rotating rod 221 connected to the output shaft of the rotary motor 220, and the support frame is fixed to the surface of the rotating rod 221.
[0043] In this embodiment, a rotatable support frame and an independently driveable tray 24 on the support frame are provided, allowing the ceramic green body placed on the tray 24 to undergo two movements simultaneously: first, it revolves around the central axis with the support frame, changing its macroscopic position within the drying chamber 12; second, the tray 24 rotates intermittently via a linkage unit. This combined movement significantly increases the contact area and angle between the green body and the hot air, breaking the airflow dead zones encountered during fixed drying, ensuring uniform heating of all surfaces of the green body and simultaneous moisture loss, effectively preventing deformation and cracking caused by uneven drying, and greatly improving drying quality and yield.
[0044] Example 2
[0045] The rapid drying equipment for ceramic green bodies provided in Example 1 has been further optimized, specifically, as follows: Figure 4 As shown, the support frame includes a first support frame 25 and a second support frame 26. The first support frame 25 and the second support frame 26 are arranged in an alternating manner in the height direction of the rotating rod 221, and the support tray 24 on the first support frame 25 corresponds to the gap between two adjacent support trays 24 on the second support frame 26 in the height direction.
[0046] By designing the support frame as a first support frame 25 and a second support frame 26, and staggering them in the height direction, the gaps between the upper support tray 24 and the adjacent lower support tray 24 correspond. This staggered layout provides more and smoother channels for the vertical flow and interpenetration of hot air when the support tray 24 rotates, optimizes the airflow organization inside the drying chamber 1, avoids airflow short-circuiting, improves heat exchange efficiency and the utilization rate of the entire drying space, thereby accelerating the overall drying speed.
[0047] Example 3
[0048] The rapid drying equipment for ceramic green bodies provided in Example 1 or 2 can be further optimized, such as... Figures 4-6 As shown, the linkage unit includes a first linkage unit 3 corresponding to the height of the first support frame 25 and a second linkage unit 4 corresponding to the height of the second support frame 26. A drive unit 5 is assembled between the first linkage unit 3 and the second linkage unit 4.
[0049] The first linkage unit 3 includes a double-sided toothed ring 31 that is sleeved on the outer side of a plurality of toothed rings 23 on the first support frame 25. A drive gear 32 is engaged on the outer side of the double-sided toothed ring 31 at the toothed ring 23 on the first support frame 25. Intermittent meshing parts 310 are evenly distributed on the inner side of the double-sided toothed ring 31. The double-sided toothed ring 31 is engaged with the toothed ring 23 through the intermittent meshing parts 310. The drive gear 32 is engaged with the outer side of the double-sided toothed ring 31.
[0050] The bottom of the double-sided toothed ring 31 is movably connected to a support ring 33. The bottom of the support ring 33 is fixed with a support member 34 that corresponds to the drive gear 32. The support ring 33 can support the double-sided toothed ring 31 without separating from it.
[0051] The first linkage unit 3 and the second linkage unit 4 have the same structure.
[0052] In this embodiment, the rotating motor 220 drives the rotating rod 221 to rotate, which in turn drives the first support frame 25 and the second support frame 26 to rotate. During the rotation, the trays 24 on the first support frame 25 and the second support frame 26 rotate synchronously. The toothed ring 23 on the outer side of the tray 24 can mesh with the double-sided toothed ring 31 on the outer side. During the uniform rotation, the tray 24 can intermittently mesh with the intermittent meshing part 310 on the inner side of the double-sided toothed ring 31. Driven by the meshing, the tray 24 can rotate on the corresponding first support frame 25 and the second support frame 26. In this way, the double rotation of the tray 24, which is both a revolution and a rotation, significantly increases the contact surface and contact angle between the green body and the hot air, breaks the dead zone of airflow during fixed drying, ensures that all surfaces of the green body are heated evenly and that moisture is lost synchronously, effectively prevents deformation and cracking caused by uneven drying, and greatly improves the drying quality and yield.
[0053] When the double-sided toothed ring 31 meshes with the toothed ring 23, the drive gear 32 is locked because it is not driven. Therefore, the double-sided toothed ring 31 meshing with the drive gear 32 is also locked, which ensures the stability of the double-sided toothed ring 31.
[0054] Example 4
[0055] The rapid drying equipment for ceramic green bodies provided in Example 3 has been further optimized, such as... Figure 4 As shown, the drive unit 5 includes a first inner support rod 51 and a second inner support rod 52. There are multiple first inner support rods 51 and second inner support rods 52. Each first inner support rod 51 passes through the support member 34 in the first linkage unit 3 in its height direction and is fixed to the drive gear 32 therein. The support member 34 is movably connected to the first inner support rod 51.
[0056] Each of the second inner support rods 52 passes through the support member 34 in the second linkage unit 4 in its height direction and is fixed to the drive gear 32 therein. The support member 34 in the second linkage unit 4 is movably connected to the second inner support rod 52.
[0057] The bottom ends of the first inner support rod 51 and the second inner support rod 52 are movably connected to the surface of the bearing plate 21. The bottom of the first inner support rod 51 and the second inner support rod 52 are fixed with a lower gear 53. The inner sides of the multiple lower gears 53 are meshed with an inner gear ring 54. The bottom of the inner gear ring 54 is movably connected to the surface of the bearing plate 21. In this way, the bearing plate 21 can support the inner gear ring 54 without affecting the movement and dislodgement of the inner gear ring 54. The inner side of the inner gear ring 54 is meshed with an inner gear 55. The bottom of the inner gear 55 is connected to a motor 56 fixed to the bearing plate 21.
[0058] The drive unit 5 further includes a first outer support rod 57 and a second outer support rod 58, which are respectively disposed on one side of the corresponding first inner support rod 51 and second inner support rod 52 and fixed to the bearing plate 21.
[0059] The first outer support rod 57 is fixed to the support member 34 in the first linkage unit 3 corresponding to its height direction, and the second outer support rod 58 is fixed to the support member 34 in the second linkage unit 4 corresponding to its height direction.
[0060] The difference between this embodiment and the above embodiment three is that in this embodiment, the starting motor 56 drives the internal gear 55 to rotate. The internal gear 55 meshes with the internal gear ring 54 on one side, and the internal gear ring 54 driven by the driving force rotates with the corresponding lower gear 53 on the outside. The rotating lower gear 53 can drive the first inner support rod 51 and the second inner support rod 52 to rotate. The first inner support rod 51 and the second inner support rod 52 in the rotating state can drive the corresponding drive gear 32 to rotate. The drive gear 32 can drive the double-sided gear ring 31 to rotate. The rotating double-sided gear ring 31 intermittently meshes with the corresponding gear ring 23 through the intermittent meshing part 310 on the inside, so as to make the tray 24 rotate and achieve self-rotation. During the drying in this rotating state, the rotary motor 220 is not started, so the rotating rod 221 can be locked.
