Description

Technical Field

[0001] This invention belongs to the field of ceramic coating drying technology, specifically referring to a drying device for ceramic coating production. Background Technology

[0002] In the precision manufacturing process of ceramic capacitors, the baseband enters a drying tunnel with controlled temperature and humidity, and undergoes a step-by-step drying process under a specific temperature gradient. By precisely controlling the solvent evaporation rate, cracking or deformation of the slurry layer is effectively avoided, ultimately resulting in a dense and stable ceramic dielectric film.

[0003] The existing drying equipment used in ceramic coating production has the following problems: In existing tunnel hot air drying channels, hot air sequentially absorbs solvent vapors volatilized from the ceramic wet film along the conveying direction. The relative humidity of the hot air gradually increases along the length of the channel, and the drying driving force continuously weakens, resulting in excessive humidity at the rear end, weak evaporation, and easy solvent residue at the bottom. At the same time, the distribution of hot air humidity is uncontrollable, leading to uneven drying and wetting in the film thickness direction, high internal stress, and unstable green body quality, which cannot meet the drying requirements of existing ceramic coating production. Summary of the Invention

[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this solution provides a drying equipment for ceramic coating production that can actively guide and discharge the high-humidity hot air floating in the upper layer of the drying channel, ensuring the overall humidity uniformity of the hot air.

[0005] The technical solution adopted in this plan is as follows: This plan proposes a drying equipment for ceramic coating production, including a support frame, an inclined plate drying component, and an expanded water storage mechanism; the inclined plate drying component includes a drying component, a merging component, an air guiding component, an exhaust component, and a drive component. The drying component is located on the upper wall of the support frame, the merging component is located at both ends of the drying component, the air guiding component is located on the top wall of the drying component, the exhaust component is located on the upper wall of the drying component, and the drive component is located on the air guiding component; the expanded water storage mechanism includes a water collecting component and an expansion component. The water collecting component is located on the air guiding component, and the expansion component is located on the water collecting component.

[0006] As a further preferred embodiment of the present invention, the drying assembly includes a drying chamber and conveyor rollers. The drying chamber is disposed on the upper wall of the support frame and is through-type. The conveyor rollers are symmetrically disposed on the inner walls of both ends of the drying chamber and are rotatably connected to the drying chamber. The mating assembly includes a mating groove, a mating block, and threaded holes. The mating groove is disposed on one side of the drying chamber and is open at one end. The mating block is disposed on the side of the drying chamber away from the mating groove. Multiple sets of threaded holes are respectively disposed on the side walls of the mating block and the mating groove. The air guiding assembly includes a groove, a rotating shaft, an air guide plate, and a flow guide channel. The groove is disposed on the top wall of the drying chamber and is open at the lower end. The rotating shaft is disposed on the inner wall of one end of the groove. The air guide plate is rotatably disposed on the outside of the rotating shaft. Multiple sets of the aforementioned guide grooves are arranged on the upper wall of the air guide plate and are open on both sides; the exhaust assembly includes a one-way exhaust valve and an exhaust fan, the one-way exhaust valve is connected to the upper wall of the drying chamber, and the exhaust fan is located on the top wall of the drying chamber below the one-way exhaust valve; the drive assembly includes a drive electromagnet, an inclined magnet, a return spring, and a humidity sensor, the drive electromagnet is installed through the upper wall of the drying chamber at the end of the air guide plate away from the rotation axis, the inclined magnet is located on the upper wall of the air guide plate and directly below the drive electromagnet, the drive electromagnet and the inclined magnet are arranged vertically opposite each other and with the same poles, the return spring is located between the air guide plate near the inclined magnet end and the top wall of the groove, and the humidity sensor is located on the inner wall of the air inlet end of the drying chamber.

[0007] During operation, hot air flows into the drying chamber from the air inlet, sequentially absorbing the solvent vapors volatilized from the ceramic wet film along the conveying direction. The relative humidity of the hot air gradually increases along the length of the drying chamber channel. The high-temperature, high-humidity airflow has a low density and easily rises and accumulates at the top of the drying chamber. A humidity sensor monitors the humidity of the hot air rising to the top of the drying chamber in real time. When the humidity of the hot air at the top of the drying chamber reaches the monitoring threshold, the high-humidity hot air is actively guided out of the drying chamber. At this time, the driving electromagnet is energized to generate magnetism, which repels the inclined magnet. This repulsive force pushes the inclined magnet, which, with the help of the elastic deformation of the return spring, pushes the air guide plate to rotate around the rotation axis and tilt. The air guide plate changes from a horizontal state to a downward tilting state, forming an angle with the top wall of the drying chamber. The high-humidity hot air at the top of the drying chamber flows into the groove under the guidance of the air guide plate. The exhaust fan operates at low speed, expelling the high-humidity hot air from the groove through a one-way exhaust valve, thus ensuring the drying effect of the hot air on the ceramic coating.

[0008] Preferably, the water collection assembly includes an arc-shaped groove, a flexible rubber pad, and a water storage tank. The arc-shaped groove is located on the upper wall of the air guide plate near the inclined magnet and is through-hole. The flexible rubber pad is located on the inner wall of the bottom of the arc-shaped groove. The water storage tank is located on the inner walls of both sides of the arc-shaped groove and is open at one end. The expansion assembly includes an arc-shaped magnet and metal columns. The arc-shaped magnet is located through-hole on the upper wall of the drying chamber above the flexible rubber pad. Multiple sets of metal columns are located on the bottom wall of the flexible rubber pad, and the metal columns and the arc-shaped magnet are arranged vertically opposite each other.

[0009] During use, the condensate droplets generated by the contact between the hot and humid air and the air guide plate slide down the guide groove and enter the water storage chamber composed of the arc-shaped groove and the flexible rubber pad. When the air guide plate rotates and tilts around the rotating axis, it moves the metal column away from the arc-shaped magnet. Under its own weight, the metal column stretches the flexible rubber pad, and the flexible rubber pad expands the water storage volume through elastic deformation, thereby increasing the amount of condensate stored. A liquid level sensor is installed on the top side wall of the arc-shaped groove to monitor the water level inside the arc-shaped groove, so as to remind the operator to drain the water in time.

[0010] Specifically, the drying oven is equipped with a controller on its side wall, which is electrically connected to the exhaust fan, the drive electromagnet, and the humidity sensor.

[0011] The beneficial effects achieved by this solution using the above structure are as follows: Compared with existing technologies, this solution combines a slanted plate drying component with an expanded water storage mechanism. Through the drying component, coupling component, air guiding component, exhaust component, drive component, water collection component, and expansion component, it can monitor the humidity of the circulating hot air inside the drying chamber in real time, actively guide and discharge the high-humidity hot air floating on the upper layer of the drying chamber, reduce the overall humidity of the hot air, and ensure the drying efficiency of ceramic coating. Multiple drying chambers can be combined to form a continuous drying channel. Multiple humidity sensor probes are arranged along the height direction on the inner wall of the upper layer of the drying chamber. When the bottom probe detects that the hot air humidity reaches the threshold, the current entering the drive electromagnet is increased, which increases the magnetic field strength between the drive electromagnet and the tilted magnet. Through repulsion, the tilted magnet is pushed, increasing the tilt angle of the air guiding plate, thereby guiding and discharging a large amount of high-humidity hot air from the upper layer of the drying chamber. This precisely controls the saturation of the hot air inside the drying chamber, further improving the drying quality and efficiency of ceramic coating in the drying channel.

[0017] like Figures 1-10As shown, the proposed drying equipment for ceramic coating production includes a support frame 1, an inclined plate drying assembly 2, and an expanded water storage mechanism 22. The inclined plate drying assembly 2 includes a drying assembly 3, a connecting assembly 6, an air guide assembly 10, an exhaust assembly 14, and a drive assembly 17. The drying assembly 3 is located on the upper wall of the support frame 1, the connecting assembly 6 is located at both ends of the drying assembly 3, the air guide assembly 10 is located on the top wall of the drying assembly 3, the exhaust assembly 14 is located on the upper wall of the drying assembly 3, and the drive assembly 17 is located on the air guide assembly 10. The expanded water storage mechanism 22 includes a water collection assembly 23 and an expansion assembly 27. The water collection assembly 23 is located on the air guide assembly 10, and the expansion assembly 27 is located on the water collection assembly 23.

[0018] The drying assembly 3 includes a drying chamber 4 and conveying rollers 5. The drying chamber 4 is disposed on the upper wall of the support frame 1 and is through-type. The conveying rollers 5 are symmetrically disposed on the inner walls of both ends of the drying chamber 4 and are rotatably connected to the drying chamber 4. The mating assembly 6 includes a mating groove 7, a mating block 8, and threaded holes 9. The mating groove 7 is disposed on one side of the drying chamber 4 and is open at one end. The mating block 8 is disposed on the side of the drying chamber 4 away from the mating groove 7. Multiple sets of threaded holes 9 are respectively disposed on the side walls of the mating block 8 and the mating groove 7. The air guiding assembly 10 includes a groove 11, a rotating shaft 12, an air guiding plate 13, and a flow guiding channel 31. The groove 11 is disposed on the top wall of the drying chamber 4 and is open at the lower end. The rotating shaft 12 is disposed on the inner wall of one end of the groove 11. The air guiding plate 13 is rotatably disposed on the outside of the rotating shaft 12. Multiple sets of flow guiding channels 31 are disposed on the air guiding plate. The upper wall of the drying chamber 4 is open on both sides; the exhaust assembly 14 includes a one-way exhaust valve 15 and an exhaust fan 16. The one-way exhaust valve 15 is connected to the upper wall of the drying chamber 4, and the exhaust fan 16 is located on the top wall of the drying chamber 4 below the one-way exhaust valve 15; the drive assembly 17 includes a drive electromagnet 18, an inclined magnet 19, a return spring 20, and a humidity sensor 21. The drive electromagnet 18 passes through the upper wall of the drying chamber 4 at the end of the air guide plate 13 away from the rotation axis 12. The inclined magnet 19 is located on the upper wall of the air guide plate 13, directly below the drive electromagnet 18. The drive electromagnet 18 and the inclined magnet 19 are arranged vertically opposite each other and with the same pole. The return spring 20 is located between the air guide plate 13 near the inclined magnet 19 and the top wall of the groove 11. The humidity sensor 21 is located on the inner wall of the air inlet end of the drying chamber 4.

[0019] The water collection assembly 23 includes an arc-shaped groove 24, a flexible rubber pad 25, and a water storage tank 26. The arc-shaped groove 24 is located on the upper wall of the air guide plate 13 near the inclined magnet 19 and is through-hole. The flexible rubber pad 25 is located on the inner wall of the bottom of the arc-shaped groove 24. The water storage tank 26 is located on the inner walls of both sides of the arc-shaped groove 24 and is open at one end. The expansion assembly 27 includes an arc-shaped magnet 28 and metal columns 29. The arc-shaped magnet 28 is located through-hole on the upper wall of the drying chamber 4 above the flexible rubber pad 25. Multiple sets of metal columns 29 are located on the bottom wall of the flexible rubber pad 25, and the metal columns 29 and the arc-shaped magnet 28 are arranged vertically opposite each other.

[0020] The drying oven 4 is equipped with a controller 30 on its side wall. The controller 30 is electrically connected to the exhaust fan 16, the drive electromagnet 18 and the humidity sensor 21 respectively.

[0021] In practical use, the operator splices multiple sets of drying boxes 4 and support frames 1 according to the required drying channel length; the mating grooves 7 and mating blocks 8 of two adjacent sets of drying boxes 4 are mated with each other, the mating blocks 8 are inserted into the mating grooves 7, and the threaded holes 9 of the mating grooves 7 and the mating blocks 8 are coaxially aligned. The drying boxes 4 are sealed with sealing strips, and bolts are screwed into the threaded holes 9 to complete the fixed connection, forming a continuous drying channel; the probes of multiple sets of humidity sensors 21 are arranged along the height direction on the upper inner wall of the drying box 4, and the ceramic wet film slowly moves along the upper wall of the conveyor roller 5 in the drying channel formed by the splicing of the drying boxes 4; In the initial state, the reset spring 20 is in a compressed state, and the air guide plate 13 remains horizontal; the arc-shaped magnet 28 is fixed to the upper wall of the drying chamber 4, and the metal column 29 is attracted by magnetic force. The metal column 29 bulges towards the inner side of the arc-shaped groove 24 by means of the elastic deformation of the flexible rubber pad 25, ensuring that the hot air flows horizontally and stably in the drying channel, making the humid hot air and the dry hot air at the bottom clearly separated, which facilitates the directional dehumidification of hot air; Hot air flows into the drying chamber 4 from the air inlet, sequentially absorbing the solvent vapors volatilized from the ceramic wet film along the conveying direction. The relative humidity of the hot air gradually increases along the length of the drying chamber 4 channel. The high-temperature, high-humidity airflow has a low density and easily rises and accumulates at the top of the drying chamber 4. Multiple humidity sensors 21 monitor the humidity of the hot air rising to the top of the drying chamber 4 in real time. When the humidity of the hot air at the top of the drying chamber 4 reaches the monitoring threshold, the high-humidity hot air is actively guided to escape. At this time, the controller 30 controls the drive electromagnet 18 to start, and the drive electromagnet 18 generates magnetism, resonating with the tilting magnet 19. The poles repel each other, and the tilted magnet 19 is pushed by the repulsive force. The tilted magnet 19, with the help of the elastic deformation of the return spring 20, pushes the air guide plate 13 to rotate and tilt around the rotation axis 12. The end of the air guide plate 13 is on the same horizontal line as the corresponding probe and forms an angle with the top wall of the drying box 4. The high humidity and hot air in the upper layer of the drying box 4 flows into the groove 11 under the guidance of the air guide plate 13. The controller 30 controls the exhaust fan 16 to start. The exhaust fan 16 runs at low speed and discharges the high humidity and hot air in the groove 11 through the one-way exhaust valve 15, reducing the humidity of the hot air in the drying channel and maintaining the stable drying efficiency of the ceramic wet film. When the air guide plate 13 rotates and tilts around the rotating axis 12, it drives the metal column 29 away from the arc-shaped magnet 28. Under its own weight, the metal column 29 stretches the flexible rubber pad 25. The flexible rubber pad 25 expands the water storage volume through elastic deformation, increasing the amount of condensate stored. A liquid level sensor is provided on the top side wall of the arc-shaped groove 24 to monitor the water level inside the arc-shaped groove 24, so as to remind the operator to drain the water in time. The condensate droplets generated by the contact between the high humidity and hot air and the air guide plate 13 slide down along the guide groove 31 into the water storage cavity formed by the arc-shaped groove 24 and the flexible rubber pad 25. When the water level inside the arc-shaped groove 24 reaches the position sensed by the liquid level sensor, the controller 30 reminds the operator to perform drainage operations; at this time, the drive electromagnet 18 is de-energized and demagnetized, and the air guide plate 13 is reset to a horizontal state under the action of the return spring 20, sealing the groove 11; the distance between the arc-shaped magnet 28 and the metal column 29 is shortened, and the arc-shaped magnet 28 attracts the metal column 29 through magnetic force. The metal column 29 drives the flexible rubber pad 25 to protrude into the arc-shaped groove 24. The upper surface of the flexible rubber pad 25 is flush with the bottom surface of the water storage tank 26, and the excess water inside the arc-shaped groove 24 flows into the water storage tanks 26 on both sides; The top wall of the drying oven 4 above the arc-shaped groove 24 has a pre-set drain hole. The operator inserts the drain pipe through the drain hole into the arc-shaped groove 24 and uses a water pump to drain the condensate. Then, the drain hole is sealed with a plug. After the water inside the arc-shaped groove 24 is drained, the liquid level sensor has no water level signal. The humidity sensor 21, based on the monitored humidity information, controls the drive electromagnet 18 through the controller 30 to drive the tilting magnet 19, adjusting the angle between the air guide plate 13 and the top wall of the drying chamber 4, and continuously guiding the high humidity and hot air out. The above operation can be repeated for the next use.

[0023] The present solution and its implementation methods have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this. In conclusion, if a person skilled in the art, inspired by this description, designs a similar structure and embodiment without departing from the inventive intent of this solution, such design should fall within the protection scope of this solution.
