Description

Technical Field

[0001] This utility model belongs to the field of ceramic processing technology, and in particular relates to a ceramic body drying device. Background Technology

[0002] Ceramic blanks are the raw materials for ceramic products, and their drying process is one of the important steps in ceramic product manufacturing. Ceramic blank drying equipment is used to evaporate the moisture in the ceramic blank, achieving a certain degree of dryness and hardness. Currently, commonly used ceramic blank drying equipment includes tunnel kilns, box kilns, and drum dryers.

[0003] Patent application CN202321548470.2 discloses a ceramic body drying device, including a drying chamber. A fixed plate is placed inside the drying chamber. The top surface of the fixed plate has a placement groove adapted to the ceramic body. A collection groove is formed inside the fixed plate. Multiple first heat dissipation holes are formed inside the fixed plate. Multiple second heat dissipation holes are formed on both the left and right sides of the fixed plate. Air inlet slots are formed on both the left and right sides of the drying chamber. Multiple exhaust holes are formed on the left and right inner walls of the drying chamber. This ceramic body drying device, through the action of the first and second heat dissipation holes, exhaust holes, and exhaust holes, dries the ceramic body from all directions, improving drying efficiency. The meshing between the driving and driven bevel gears drives the placement plate to rotate, thereby rotating the ceramic body, further improving drying efficiency and making it more convenient and practical.

[0004] Existing technologies use multiple heat dissipation holes to rotate and dry ceramic blanks, which improves drying efficiency, but still has shortcomings:

[0005] First, existing drying equipment lacks internal support for thin-walled ceramic blanks when drying them, which makes the ceramic blanks prone to deformation during the drying process, resulting in a low yield of dried ceramic blanks.

[0006] Secondly, existing drying equipment lacks a structure to filter the moisture in the hot air, causing the water vapor generated during the drying of the ceramic blank to circulate continuously inside the chamber, thus affecting the drying efficiency of the ceramic blank. Summary of the Invention

[0007] To overcome the shortcomings of existing technologies, this invention provides a ceramic blank drying device. By incorporating components such as a folded support film, this invention provides support for the ceramic blank placed on the upper surface of the rotating disk, effectively preventing deformation during drying and improving simultaneous drying of the inner and outer surfaces. Furthermore, by using components such as a limiting plate, the folded support film can be compressed and folded for easier placement of the ceramic blank.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a ceramic body drying device, comprising a box body, a door hinged to one side of the box body, multiple vertically placed rotating disks rotatably arranged inside the box body, multiple second ventilation holes provided on the upper surface of each rotating disk, an air circulation assembly for blowing air from bottom to top provided on the outside of the multiple rotating disks, a vertically retractable folding support membrane provided on the upper surface of each rotating disk at the upper port of the second ventilation hole, a flexible support membrane provided on the upper port of each folding support membrane, and multiple elastic limiting components provided on the outside of each folding support membrane, the output end of the elastic limiting components restricting the vertical retraction of the adjacent folding support membrane.

[0009] Optionally, the elastic limiting component includes a vertical plate disposed on the upper surface of the rotating disk, a limiting plate rotatably connected to the top of the vertical plate, the limiting plate engaging with the folds outside the folded support membrane to limit movement, and an elastic element connecting the vertical plate and the limiting plate to provide elastic limiting for rotation between the vertical plate and the limiting plate.

[0010] Optionally, each of the folded support membranes has multiple support blocks on the upper surface of the rotating disk.

[0011] Optionally, each of the folded support membranes has a plurality of third ventilation holes on its outer wall.

[0012] Optionally, each of the rotating disks has a plurality of first ventilation holes on its upper surface.

[0013] Optionally, the wind circulation assembly includes a support plate disposed inside the housing, the support plate being located below multiple rotating discs, and multiple exhaust fans disposed inside the support plate, each exhaust fan capable of transporting air below the support plate to above the support plate. An arc-shaped heat-conducting plate is connected between the housing and the support plate at the inner corner of the housing, and each arc-shaped heat-conducting plate, the housing, and the support plate form a connecting pipe. Multiple fourth ventilation holes are disposed near the top of each arc-shaped heat-conducting plate inside the housing. A mesh plate is disposed between the input end of each exhaust fan and the inner bottom surface of the housing, and drying particles are disposed inside the space formed by the housing and the support plate on the outside of each mesh plate.

[0014] Optionally, a heater is provided above each of the arc-shaped heat-conducting plates on the upper surface of the housing, and the output end of each heater extends through the housing and into the space formed by the housing and the arc-shaped heat-conducting plate.

[0015] Optionally, a rotating rod is rotatably connected between the housing and the support plate. Each rotating rod is rotatably engaged with each rotating disk. Multiple first air inlets are connected at the rotatable connection between the support plate and the rotating rod. Multiple fifth ventilation holes are provided on the outer circumference of the rotating rod.

[0016] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0017] This invention, through the arrangement of components such as a rotating disk, a folded support film, and a flexible support film, can form a support for the ceramic blank placed on the upper surface of the rotating disk outside the folded support film. At the same time, it can also form a support for the inside of the ceramic blank through the folding mechanism of the folded support film and multiple third ventilation holes. This effectively prevents the ceramic blank from deforming during the drying process, while also improving the synchronous drying of the inside and outside of the ceramic blank, and preventing the ceramic blank from cracking due to excessive difference in internal drying rate.

[0018] This utility model, through the arrangement of components such as a support plate, an arc-shaped heat-conducting plate, and an exhaust fan, forms a circulation of hot air inside the box and a drying process for the circulated hot air, thereby improving the air circulation efficiency inside the box and also effectively improving the drying efficiency of the ceramic blank inside the box.

[0019] This invention, through the setting of components such as support blocks, vertical plates, and limiting plates, can compress and fold the folded support film in advance when the ceramic blank is placed on the upper surface of the rotating disk, which facilitates the placement of the ceramic blank, thereby reducing the distance between each two adjacent rotating disks and increasing the drying quantity of ceramic blanks inside the box.

Detailed Implementation

[0028] 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 of the present invention. Example 1:

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a ceramic blank drying device includes a housing 10. A door 31 is hinged to one side of the housing 10. Multiple vertically placed rotating disks 13 are rotatably mounted inside the housing 10. Operators can open the door 31 and then place multiple ceramic blanks sequentially onto the end face of each rotating disk 13. Each rotating disk 13 has multiple first ventilation holes 14 on its upper end face. During the drying process, a large amount of dry gas flows from bottom to top through the first ventilation holes 14 onto the outer surface of the ceramic blank, thus drying it. In this design, the multiple first ventilation holes 14 increase the airflow between the upper and lower end faces of the rotating disks 13, thereby improving the drying efficiency of the ceramic blanks placed on the upper end face of the rotating disks 13. A rotating rod 12 is rotatably connected between the box body 10 and the support plate 11. The rotating rod 12 is rotatably connected to each rotating disk 13. The rotatable connection between the rotating rod 12 and the rotating disk 13 allows the rotating disk 13 to rotate at an appropriate angle after a single ceramic blank is placed, so that the empty part can be rotated to the side of the box door 31, allowing the staff to place it quickly. A drive motor is provided on the lower end of the box body 10. The output end of the drive motor passes through the box body 10 and the support plate 11 and is fixedly connected to the bottom of the rotating rod 12. The drive motor is a common motor and is existing technology. The drive motor drives the rotating rod 12 to rotate, which in turn drives the rotating disk 13 to rotate, so that the ceramic blanks placed on the upper end of the rotating disk 13 can be circulated and rotated, thereby improving the drying efficiency.

[0030] Each rotating disk 13 has multiple second ventilation holes 16 on its upper surface. A bottom-up air circulation assembly is installed on the exterior of each rotating disk 13. Each rotating disk 13 has a vertically extendable folded support membrane 17 at the upper end of the second ventilation hole 16. The folded support membrane 17 is made of an elastic material and is corrugated. Each folded support membrane 17 has a flexible support membrane 18 made of elastic material at its upper end. When placing the ceramic blank, it should be placed upside down with the bottle mouth facing down outside the folded support membrane 17. At this time, the inner cavity of the ceramic blank and the outer surface of the folded support membrane 17 are close to each other. The second ventilation holes 16 allow a large amount of airflow to quickly impact the interior of the folded support membrane 17 as it flows upwards. Therefore, the folded support membrane 17 elastically elongates under the impact of the internal airflow. The elastically deformable folded support membrane 17 gradually comes into contact with the inner wall of the ceramic blank, thereby forming support for the inside of the ceramic blank. Each folded support membrane 17 is provided with multiple elastic limiting components on its exterior. The output end of the elastic limiting components restricts the vertical expansion and contraction of the adjacent folded support membrane 17, thereby reducing the overall height of the folded support membrane 17, which facilitates the placement of the ceramic blank, and also reduces the distance between the rotating disks 13, so that more rotating disks 13 can be placed inside the box 10 of the same size, thereby allowing more ceramic blanks to be placed for drying. Each folded support membrane 17 is provided with multiple third ventilation holes 19 on its inner sidewall. The multiple third ventilation holes 19 allow the air inside the folded support membrane 17 to also come into contact with the inner wall of the ceramic blank through the third ventilation holes 19, thereby improving the drying efficiency inside the ceramic blank.

[0031] Each rotating disk 13 has a downward-sloping wind-gathering ring 15 on its outer circular surface. The wind-gathering ring 15 can gather the wind force blown upward from below the rotating disk 13, so that more wind force can be used to air-dry the inner and outer walls of the ceramic body through multiple first ventilation holes 14 and second ventilation holes 16.

[0032] Furthermore, such as Figure 3 and Figure 4As shown, the wind circulation assembly includes a support plate 11 disposed inside the housing 10. The support plate 11 is located below multiple rotating disks 13. Multiple exhaust fans 28 are disposed inside the support plate 11, and each exhaust fan 28 can transport air below the support plate 11 to the top of the support plate 11. Arc-shaped heat-conducting plates 24 are connected between the housing 10 and the support plate 11 at the inner corner of the housing 10. Each arc-shaped heat-conducting plate 24 forms a connecting pipe with the housing 10 and the support plate 11. Multiple fourth ventilation holes 27 are provided near the top of the housing 10. The exhaust fans 28 are ordinary exhaust fans that can blow air below the support plate 11 to the top of the support plate 11, and then enter the interior of the folded support membrane 17 through multiple second ventilation holes 16, forming an internal drying of the ceramic body, and allowing air circulation in the upper and lower spaces of the multi-layer rotating disks 13 through multiple first ventilation holes 14, so that each folded support membrane 17... The interior of the 7 has sufficient air pressure to support the inner walls of the folded support film 17 and the flexible support film 18, thereby ensuring the dryness of the inner and outer walls of the ceramic body and providing support for the interior of the ceramic body. Air circulates through the channels formed by multiple fourth ventilation holes 27, the arc-shaped heat-conducting plate 24, and the box 10 into the space between the lower end face of the support plate 11 and the box 10, thus forming air circulation inside the box 10. A mesh plate 29 is provided between the input end of each exhaust fan 28 and the inner bottom surface of the box 10. Drying particles are provided on the outside of each mesh plate 29 and inside the space formed by the box 10 and the support plate 11. The setting of the drying particles can filter the moisture in the air during the air circulation inside the box 10, thereby effectively improving the drying efficiency of the ceramic body. The setting of the mesh plate 29 can effectively prevent the drying particles from entering the interior of the exhaust fan 28 under the suction of the exhaust fan 28.

[0033] Furthermore, such as Figure 3 and Figure 4 As shown, a heater 25 is provided above each arc-shaped heat-conducting plate 24 on the upper surface of the box 10. The output end of each heater 25 extends through the box 10 and into the space formed by the box 10 and the arc-shaped heat-conducting plate 24. The heater 25 is a common heater, which is existing technology. The setting of the heater 25 can heat the air between the arc-shaped heat-conducting plate 24 and the box 10, so that the air can be heated during the circulation inside the box 10. At the same time, the output end of the heater 25 transfers heat to the arc-shaped heat-conducting plate 24, thereby increasing the heat of the arc-shaped heat-conducting plate 24 itself, and thus heating the ceramic blank placed on the upper surface of the rotating disk 13. With the rotation of the rotating rod 12 and the rotating disk 13, a circulating heating and drying of the outside of the ceramic blank is formed, improving the drying efficiency of the ceramic blank.

[0034] Furthermore, such as Figure 6As shown, the elastic limiting assembly includes a vertical plate 21 disposed on the upper surface of the rotating disk 13. A limiting plate 22 is rotatably connected to the top of the vertical plate 21. The limiting plate 22 engages with the folds on the outside of the folded support film 17 to limit the movement. An elastic element 23 is connected between the vertical plate 21 and the limiting plate 22. The elastic tension of the elastic element 23 itself forms an elastic limit on the rotation between the vertical plate 21 and the limiting plate 22, so that when the ceramic body is placed, the limiting plate 22 and the vertical plate 21 can fold and compress the folded support film 17, thereby reducing the overall height of the folded support film 17. The smaller size facilitates the placement of ceramic blanks and also reduces the distance between rotating discs 13, allowing more rotating discs 13 to be placed inside the same-sized box 10, thus enabling more ceramic blanks to be placed for drying. When the exhaust fan 28 blows air from bottom to top, the air enters the folded support membrane 17 through the second ventilation hole 16, creating an upward impact force on the inner wall of the folded support membrane 17. Combined with the elastic tension of the folded support membrane 17 itself, the vertical height of the folded support membrane 17 is restored, thereby providing support for the interior of the ceramic blank.

[0035] Furthermore, such as Figure 5 As shown, each folded support film 17 has multiple support blocks 20 on the upper surface of the rotating disk 13. The arrangement of multiple support blocks 20 can raise the ceramic body as a whole, thereby increasing the gap between the ceramic body and the rotating disk 13, facilitating the circulation of air inside and outside the ceramic body, and improving the drying efficiency. Example 2:

[0036] Based on Example 1, further examples are made, such as... Figure 3 and Figure 7 As shown, the rotational connection between the support plate 11 and the rotating rod 12 is provided on the upper end surface of the support plate 11, where multiple first air inlets 32 are provided to connect the space below the support plate 11 and the internal space of the rotating rod 12. Multiple fifth ventilation holes 33 are provided on the outer circular surface of the rotating rod 12. The arrangement of the first air inlets 32 and the fifth ventilation holes 33 allows external air to enter the interior of the rotating rod 12 through the multiple fifth ventilation holes 33, and then enter the space between the support plate 11 and the box 10 through the first air inlets 32. The air inside the box 10 is further circulated by multiple exhaust fans 28, effectively improving the drying efficiency of the ceramic blank.
