Description

Technical Field

[0001] This utility model relates to a drying device, and more particularly to a ceramic roller infrared drying device. Background Technology

[0002] In ceramic industrial production, roller kilns are key thermal equipment for continuous firing of ceramic blanks. Their core transmission and load-bearing components are ceramic rollers, which are usually made of high-purity mullite, alumina and other high-temperature resistant materials. They have good thermal stability and bending strength. They operate in a complex environment with high temperature, high humidity and a lot of dust for a long time. During use, the surface of the rollers is easily contaminated with dust from the blanks, glaze droplets, carbon deposits and oil stains. This not only affects the smoothness of their rotation, but may also cause quality problems such as scratches, deformation or deviation of ceramic products.

[0003] Therefore, before replacing, repairing, or shutting down the kiln for an extended period, the rollers must be thoroughly cleaned and deeply dried. If residual moisture is not completely removed from the inside of the rollers after cleaning, they will rapidly vaporize and generate internal stress when directly introduced into the high-temperature kiln, which can easily cause the rollers to crack or even burst, seriously threatening the safe operation of the kiln. Currently, the drying of ceramic rollers mostly relies on hot air drying. Although hot air drying can accelerate the evaporation of surface moisture, heat transfer mainly depends on convection, which results in slow heating, low efficiency, and difficulty in penetrating the microporous structure of the rollers, leading to residual moisture inside.

[0004] Therefore, it is necessary to design a ceramic roller infrared drying device. Utility Model Content

[0005] In order to overcome the shortcomings of hot air drying, such as slow heating, low efficiency, and difficulty in penetrating the microporous structure of the roller, resulting in residual moisture inside the ceramic roller, the technical problem of this utility model is to provide an infrared drying device for ceramic rollers.

[0006] The technical solution is as follows: A ceramic roller infrared drying device includes a drying chamber, a base, support feet, a chamber door, a control console, infrared drying lamps, support blocks, mounting frames, fixing blocks, and springs. A base is fixedly installed on the lower end face of the drying chamber, and four support feet are fixedly installed in a rectangular array on the lower end face of the base. A chamber door is connected to the front side of the drying chamber via hinges. A control console is fixedly installed on the front side of the right side wall of the drying chamber. A certain number of infrared drying lamps are fixedly installed at the top and bottom of the drying chamber. Two support blocks are fixedly connected to the middle of the left and right side walls of the drying chamber. The two support blocks on the same side form a sliding support structure. A mounting frame is slidably provided between the two support blocks on both sides. A certain number of limiting protrusions are fixedly provided on the lower front and rear sides of the mounting frame. Fixing blocks corresponding to the limiting protrusions are connected to the upper front and rear sides of the mounting frame via springs. The control console is electrically connected to the infrared drying lamps.

[0007] Preferably, all components inside the drying oven are made of high-temperature resistant materials.

[0008] Preferably, the oven also includes an observation window and a sealing ring. An observation window is fixedly provided on the upper part of the oven door, and a sealing ring is fixedly connected to the circumference of the rear end face of the oven door. A sealing groove corresponding to the sealing ring is provided on the circumference of the front end face of the drying oven. When the oven door is closed, the sealing ring is embedded in the sealing groove.

[0009] As a preferred option, the viewing window can block infrared rays.

[0010] As a preferred option, it also includes air inlets, with air inlets provided on the upper part of both the left and right side walls of the drying chamber. Air guide plates are provided at both the left and right air inlets, with the right air guide plate being an air intake type and the left air guide plate being an air outlet type.

[0011] Preferably, the assembly also includes slide rails, a lifting frame, sliding seats, a screw, a motor, a guide rod, and a lifting plate. Slide rails are fixedly installed on both sides of the bottom surface of the drying chamber. Sliding seats are slidably provided on both slide rails. A lifting frame is fixedly connected to the upper front side of the two sliding seats. A screw is rotatably installed on the left side inside the lifting frame. The upper end of the screw is rotatably inserted above the lifting frame. A motor is fixedly connected to the upper left side of the lifting frame. The motor output shaft is fixedly connected to the screw. A guide rod is fixedly installed on the right side inside the lifting frame. A lifting plate is provided between the screw and the guide rod. The lifting plate is threadedly connected to the screw and slidably connected to the guide rod.

[0012] The present invention has the following advantages: 1. The present invention uses infrared drying lamps to emit infrared rays, which directly act on the water molecules inside the ceramic rollers to generate heat through resonance, thereby achieving rapid and uniform heating and drying from the inside out, significantly improving drying efficiency and preventing cracking or bursting caused by moisture vaporization after entering the kiln.

[0013] 2. This utility model, by setting up a lifting and translation feeding mechanism composed of a slide rail, a sliding seat, a lifting frame, a screw, a motor, a guide rod, and a lifting plate, achieves the effect of smoothly and accurately sending the rollers into the designated position in the drying chamber after the rollers are installed in the loading area through lifting and horizontal sliding, which is convenient for operation and avoids collision damage to the rollers during transportation.

The base 2 is screwed onto the lower end of the drying chamber 1. Four support feet 3 are screwed onto the lower end of the base 2 in a rectangular array. The door 4 is hinged to the front of the drying chamber 1. The control console 5 is screwed onto the front right side wall of the drying chamber 1. A certain number of infrared drying lamps 6 are screwed onto the top and bottom of the drying chamber 1. Two support blocks 7 are fixed to the middle of the left and right side walls of the drying chamber 1. The two support blocks 7 on the same side form a sliding support structure. The mounting frame 8 is slidably provided between the two support blocks 7 on both sides. A certain number of limiting protrusions are fixed to the lower front and rear sides of the mounting frame 8. The upper front and rear sides of the mounting frame 8 are connected to fixing blocks 9 corresponding to the limiting protrusions by springs 10. The control console 5 is electrically connected to the infrared drying lamps 6. All components inside the drying chamber 1 are made of high-temperature resistant materials.

[0021] like Figure 1 and Figure 2 As shown, it also includes an observation window 41 and a sealing ring 42. The observation window 41 is fixedly opened on the upper part of the door 4, and the sealing ring 42 is fixedly connected to the circumference of the rear end face of the door 4. The sealing groove 43 corresponding to the sealing ring 42 is opened on the circumference of the front end face of the drying oven 1. When the door 4 is closed, the sealing ring 42 is embedded in the sealing groove 43, and the observation window 41 can block infrared rays.

[0022] like Figure 1 and Figure 2 As shown, it also includes an air inlet 11. Air inlets 11 are provided on the upper part of both the left and right side walls of the drying chamber 1. Air guide plates are provided at both the left and right air inlets 11. The right air guide plate is installed in the air intake type, and the left air guide plate is installed in the air outlet type.

[0023] like Figure 2 , Figure 4and Figure 5 As shown, it also includes slide rails 12, lifting frame 13, sliding seat 14, screw 15, motor 16, guide rod 17, and lifting plate 18. Slide rails 12 are installed on both sides of the bottom surface of the drying oven 1 by screws. Sliding seats 14 are slidably provided on both slide rails 12. Lifting frame 13 is fixedly connected to the upper front side of the two sliding seats 14. Screw 15 is rotatably installed on the left side of the lifting frame 13. The upper end of screw 15 is rotatably inserted above the lifting frame 13. Motor 16 is fixedly connected to the upper left side of the lifting frame 13. The output shaft of motor 16 is fixedly connected to screw 15. Guide rod 17 is fixedly installed on the right side of the lifting frame 13. Lifting plate 18 is provided between screw 15 and guide rod 17. Lifting plate 18 is threadedly connected to screw 15 and slidably connected to guide rod 17.

[0024] When using this ceramic roller infrared drying device, first place the ceramic rollers from right to left onto the limiting protrusions on the lower front and rear sides of the mounting frame 8. Then, press the fixing blocks 9 connected to the upper front and rear sides of the mounting frame 8 by springs 10. The springs 10 are compressed, creating a clamping space between the fixing blocks 9 and the limiting protrusions, thus firmly clamping the ceramic rollers between the limiting protrusions and the fixing blocks 9. This completes the pre-installation of multiple rollers. Then, place the mounting frame 8 with the rollers on the lifting plate 18, open the door 4, align the sliding seats 14 on the left and right sides of the bottom of the lifting frame 13 with the slide rails 12, and start the motor 16. The output shaft of motor 16 drives screw 15 to rotate. Since lifting plate 18 is threadedly connected to screw 15 and slidably connected to guide rod 17, the rotational motion of screw 15 is converted into linear lifting motion of lifting plate 18. Lifting plate 18 drives mounting frame 8 and rollers to rise as a whole until mounting frame 8 is level with the support block 7 in the middle of the left and right side walls inside drying chamber 1. At this time, motor 16 is turned off, and lifting frame 13 is manually pushed so that sliding seat 14 slides along slide rail 12, pushing lifting frame 13, sliding seat 14, lifting plate 18 and mounting frame 8 horizontally into drying chamber 1. Mounting frame 8 slides in simultaneously. In the sliding support structure composed of side support blocks 7, the rollers are precisely positioned and supported. Then, the lifting frame 13 is slid out of the drying chamber 1 in the reverse direction, and the chamber door 4 is closed. The sealing ring 42 on the rear end of the chamber door 4 is embedded in the sealing groove 43 on the front end of the drying chamber 1, ensuring the interior of the drying chamber 1 is sealed. The drying program is started via the control console 5, which supplies power to the infrared drying lamp 6. The infrared drying lamp 6 emits infrared rays, which penetrate the surface of the ceramic rollers and directly act on the water molecules inside, triggering molecular resonance to generate heat. This achieves rapid and uniform heating and drying from the inside out. Simultaneously, the left and right side walls of the drying chamber 1... The upper air inlet 11, together with the air guide plate, forms air convection. The right air inlet air guide plate introduces external air, and the left air outlet air guide plate discharges hot and humid air, promoting the removal of moisture from the chamber and accelerating the drying process. The observation window 41 on the chamber door 4 can block infrared rays, allowing operators to safely observe the drying status of the rollers inside the drying chamber 1 from the outside. After drying is completed, turn off the infrared drying lamp 6 and the power of the motor 16. After the temperature drops, slide the lifting frame 13 back in, start the motor 16 to lower the lifting plate 18, lower the mounting frame 8 and the dried rollers, and then slide the lifting frame 13 out as a whole to remove the rollers.
