Description

Technical Field

[0001] This invention relates to the field of ceramic production technology, specifically to a drying device for producing daily-use ceramic products. Background Technology

[0002] Ceramics is a general term encompassing pottery and porcelain. Traditional ceramics, also known as ordinary ceramics, are products made primarily from natural silicates such as clay. Modern ceramics, also called new ceramics, fine ceramics, or special ceramics, are often manufactured using non-silicate chemical raw materials or synthetic raw materials, such as oxides like alumina, zirconium oxide, and titanium oxide, and non-oxides like silicon nitride and boron carbide. Ceramic production requires drying during the forming process.

[0003] Existing drying equipment requires opening the device to remove the dried ceramic products after drying, resulting in a large amount of heat dissipating to the outside and cold air entering the device. When drying again, the air inside the device needs to be reheated, which cannot guarantee the temperature inside the device, increases the energy consumption of drying, and is not conducive to use. Summary of the Invention

[0004] The purpose of this invention is to provide a drying apparatus for the production of daily-use ceramic products, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a drying device for daily-use ceramic products, comprising a drying device, the drying device including a base, a drying chamber, a supporting component, and a heating device, the drying chamber being mounted on the base, the supporting component being rotatably disposed inside the drying chamber, the heating device being disposed in the middle of the drying chamber and connected to the base, and the supporting component being disposed around the heating device; the supporting component is provided with a plurality of sealing mechanisms, the sealing mechanisms being movably disposed on the supporting component and driven by a driving mechanism to open and close, the plurality of sealing mechanisms being closed, which can divide the space inside the supporting component into multiple drying chambers, each drying chamber being used to place ceramic blanks with different drying time requirements, and adjacent drying chambers being connected by an air pump for exchanging hot air between the two drying chambers.

The several support frames are arranged vertically between the top plate and the bottom plate, and the edges of the several support frames are connected as a whole by several brackets. The upper and lower ends of the brackets are fixedly connected to the top plate and the bottom plate, respectively. The sides of the top plate, the bottom plate, and the support frames are rotatably connected to the inner wall of the drying chamber. A toothed ring is provided at the bottom end of the bottom plate. A motor is installed in the base. The output shaft of the motor is meshed with the toothed ring to drive the support frames to rotate.

[0007] Furthermore, the support net consists of several annular support pipes with gradually increasing sizes and several air supply pipes. An air guide plate is connected to the inner ring side of the support frame. The longitudinal dimension of the air guide plate is larger than the longitudinal dimension of the support frame, and an air inlet is provided on the side of the air guide plate closest to the heating device. Several support pipes are arranged at equal intervals on the support frame. The air supply pipes are vertically arranged on the support pipes and the two are internally connected. The input end of the air supply pipe is connected to the air inlet. Several air outlets are opened at the top of the support pipes.

[0008] Furthermore, the number of sealing mechanisms is three sets, and the three sets of sealing mechanisms divide the support frame into three drying chambers.

The second sealing component is disposed on the support frame, and one end of the second sealing component is connected to the first sealing component, and the other end is connected to the outer side of the support frame and moves against the inner wall of the drying chamber.

[0009] Furthermore, the first sealing assembly includes several first rotating rods and several arc-shaped plates. The several first rotating rods are rotatably arranged at equal intervals between the middle of the top plate and the middle of the bottom plate. The surface of the first rotating rods is distributed with several arc-shaped plates, and each arc-shaped plate is located to the side of the air guide plate. The second sealing assembly includes several second rotating rods and several sealing plates. Several fixed frames corresponding to the second sealing assembly are on the support net. The support and the fixed frames are connected. The second rotating rods are rotatably arranged at equal intervals between the middle of the top plate and the middle of the bottom plate, and the second rotating rods pass through the fixed frames on each support net in sequence. The surface of the second rotating rods is provided with several sealing plates. The sealing plates are located at the upper end of the support net. After the arc-shaped plates and the sealing plates rotate and splice together, they divide the inner space of the corresponding support net into sealing chambers.

[0010] Furthermore, the drive mechanism includes several electric motors, the upper ends of the first rotating rod and the second rotating rod both extend through to the upper side of the top plate, and the top ends of the first rotating rod and the second rotating rod are both equipped with pulleys, and a synchronous belt is sleeved between the pulleys of each first rotating rod on a set of first sealing assemblies and the pulleys of each second rotating rod on an adjacent set of second sealing assemblies, and one of the second rotating rods on the first sealing assembly is connected to an electric motor to drive rotation.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1.

[0016] 2. This invention, through the combined use of a sealing component and an air pump, can transfer and reuse the hot air generated during drying. When handling ceramic blanks, it can greatly reduce the outflow of hot air, thereby reducing heat loss within the device, ensuring stable temperature within the device, improving drying effect, and facilitating use.

[0017] 3.

The support frames 5 and the bottom plate 9 are both ring-shaped. The heating device 3 is located in the middle of the support frames 5 and the bottom plate 9. The several support frames 5 are arranged vertically between the top plate 8 and the bottom plate 9, and the edges of the several support frames 5 are connected as one unit by several brackets 6. The upper and lower ends of the brackets 6 are fixedly connected to the top plate 8 and the bottom plate 9, respectively.

[0029] Please see Figure 4 As shown, the support net 7 consists of several annular support pipes 12 with gradually increasing size and several air supply pipes 13. The inner ring side of the support frame 5 is connected to an air guide plate 14. The longitudinal dimension of the air guide plate 14 is larger than the longitudinal dimension of the support frame 5, and an air inlet 15 is provided on the side of the air guide plate 14 that is close to the heating device 3.

[0031] Please see Figure 3 and Figure 5As shown, the first sealing assembly 17 includes several first rotating rods 19 and several arc-shaped plates 20. The several first rotating rods 19 are rotatably arranged at equal intervals between the middle of the top plate 8 and the middle of the bottom plate 9. The surface of the first rotating rods 19 is distributed with several arc-shaped plates 20, and each arc-shaped plate 20 is located on the side of the air guide plate 14. The second sealing assembly 18 includes several second rotating rods 21 and several sealing plates 22. Several fixed frames 23 corresponding to the second sealing assembly 18 are on the support net 7. The bracket 6 and the fixed frames 23 are connected. The second rotating rods 21 are rotatably arranged at equal intervals between the middle of the top plate 8 and the middle of the bottom plate 9. The second rotating rods 21 pass through the fixed frames 23 on each support net 7 in sequence. The surface of the second rotating rods 21 is provided with several sealing plates 22. The sealing plates 22 are located at the upper end of the support net 7. After the arc-shaped plates 20 and the sealing plates 22 rotate and splice together, they divide the inner space of the corresponding support net 7 into sealed chambers.

[0032] Please see Figure 1 and Figure 6 As shown, the drive mechanism includes several motors 26. The upper ends of the first rotating rod 19 and the second rotating rod 21 both extend through to the upper side of the top plate 8. The top ends of the first rotating rod 19 and the second rotating rod 21 are equipped with pulleys 24. A synchronous belt 25 is provided between the pulleys 24 of each first rotating rod 19 on a set of first sealing assemblies 17 and the pulleys 24 of each second rotating rod 21 on an adjacent set of second sealing assemblies 18. One of the second rotating rods 21 on the first sealing assembly 17 is connected to the motor 26 to drive rotation.

[0033] Please see Figure 1 As shown, the air pump 4 is installed on the top surface of the top plate 8. The input and output ends of the air pump 4 are connected to the two sides of the second sealing component 18 through pipes. The heating device 3 includes a heating chamber, several sets of heating wires and a fan. The heating chamber is assembled in the middle of the drying chamber 2. The heating wires are evenly distributed in the heating chamber. Several air outlets are opened on the outer periphery of the heating chamber. The fan is installed at the bottom of the heating chamber.

[0034] The working principle of this embodiment is as follows:

[0035] When using this device, the operator first places the ceramic blank on the support net 7, and according to the different drying time requirements of different shaped ceramic blanks, ceramic blanks with similar drying time requirements are placed in the same drying chamber. During the drying process, the air blown in is directly heated by the heating wire, and then sent into the drying chamber 2 from the air outlet of the heating chamber. At the same time, during the heating and drying process, the air inlet 15 is opened on the air guide plate on the inner side of the support net 7 to facilitate the entry of heat. The hot air can dry the bottom of the ceramic blank through the air outlet 16 along the air supply pipe 13, avoiding uneven drying that could cause cracks in the ceramic blank.

[0036] After the ceramic blanks in one drying chamber are dried, the motor 11 drives the entire supporting assembly to rotate, causing the drying chamber to rotate to the opening. Then, the first sealing assembly 17 and the second sealing assemblies 18 on both sides of the drying chamber begin to work. The output shaft of the motor 11 rotates, causing the arc plate 20 to rotate from a vertical position to a horizontal position. The synchronous belt 25 drives the sealing plate 22 to rotate as well, so that the arc plates 20 and the sealing plates 22 are joined together, thus separating the drying chamber from other drying chambers. After the arc plate 20 closes, it will also block the air guide plate 14. Then, the air pump 4 starts to work, drawing the hot air in the drying chamber to other drying chambers, thus transferring the heat of the drying chamber to other places. The operator can then open the sealing door 27 to remove the ceramic blanks from the drying chamber. This greatly reduces the outflow of hot air, thereby reducing the heat loss in the device and ensuring the stability of the temperature inside the device.

[0037] When a new ceramic blank is placed in the drying chamber for drying, the first sealing component 17 and the second sealing component 18 are opened to allow the hot gas phase to circulate, and the drying chamber can be heated quickly, saving preheating time.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
