Description

Technical Field

[0001] This utility model belongs to the field of ceramic tile production technology, and specifically relates to a uniform drying device for ceramic tile blanks. Background Technology

[0002] Currently, the common production process for ceramic tiles mainly includes core steps such as raw material preparation, batching and ball milling, spray drying, pressing and molding, drying, glazing, firing, polishing, and inspection and packaging. Among these, drying involves sending the shaped ceramic tile blanks to a hot air drying chamber for dehydration treatment, reducing their moisture content to a suitable percentage to prevent deformation during subsequent firing. However, in the current ceramic tile blank drying process, batches of ceramic tile blanks are typically loaded onto movable racks, and then the racks are sent into the hot air drying chamber. During a single drying operation, there may be multiple racks in the hot air drying chamber, but the air outlets are fixed. This results in the ceramic tile blanks on racks closer to the air outlets drying more thoroughly than those further away. The uneven drying levels on different racks at the same time lead to inconsistent drying quality within the same batch of ceramic tile blanks, which is detrimental to subsequent processing and production and needs to be addressed. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a uniform drying device for ceramic tile blanks to solve the above problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a uniform drying device for ceramic tile blanks, comprising a hot air blower, a blower, a hot air drying chamber, and several movable material racks. The front of the hot air drying chamber is open and closable, and a main air inlet pipe is fixedly installed on its outer top. The air outlet of the hot air blower is connected to the air inlet of the blower, and the air outlet of the blower is connected to one end of the main air inlet pipe. Several branch air inlets, spaced apart along its axial direction, are fixedly connected to the bottom of the main air inlet pipe, and the branch air inlets extend into the hot air drying chamber. The drying chamber is fixedly connected to a flexible hose. A single-rod hydraulic cylinder is fixedly installed on the top of the hot air drying chamber on one side of the air inlet branch pipe. The piston rod of the single-rod hydraulic cylinder faces downward and is detachably connected to a hollow lifting plate. The top of the lifting plate is connected to the adjacent flexible hose through a quick connector. Several inverted L-shaped air ducts are fixedly connected to the front, back, left, and right sides. Several nozzles are provided on the inner side of the vertical part of each air duct. The movable material rack is located below the lifting plate and is fixed by a limiting device. The air duct is located on the periphery of the corresponding movable material rack.

[0005] Preferably, the piston rod of the single-rod hydraulic cylinder is fixedly connected to a support base at its bottom end, and a double-rod hydraulic cylinder is fixedly mounted through the support base. Both piston rods of the double-rod hydraulic cylinder are fixedly connected to rectangular limiting frames. A mounting base is fixedly mounted at the bottom of the support base, and a positioning groove is opened at the bottom of the mounting base. A positioning block is fixedly connected to the top of the lifting plate, and the positioning block is inserted into the corresponding positioning groove. The limiting frames are fitted onto the left and right sides of the mounting base and the positioning block.

[0006] Preferably, the limiting frame is adapted to the mounting base, and the positioning block is adapted to the positioning groove.

[0007] Preferably, the movable rack includes a base, with casters installed at the four corners of the bottom of the base, and a plurality of perforated plates arranged at vertical intervals on the top of the base. The perforated plates are fixedly connected to each other and to the base by pillars at the four corners.

[0008] Preferably, the limiting device includes a baffle fixedly connected to the rear side of the base, a rectangular positioning seat fixedly provided on the rear side of the baffle, a rectangular locking seat rotatably connected to the rear side of the positioning seat, a back plate fixedly provided in the hot air drying chamber at the rear of the base, a through groove provided on the back plate, the baffle abutting against the front side of the back plate, the positioning seat being inserted into the through groove, the locking seat passing through the corresponding through groove and its front side being flush with the rear side of the back plate, and the locking seat abutting against the rear side of the back plate after rotating 90 degrees.

[0009] Preferably, both the positioning seat and the locking seat are adapted to the corresponding through slot.

[0010] Preferably, a traction ring is fixed on the front side of the base.

[0011] Preferably, the top of the hot air drying room is connected to an exhaust pipe.

[0012] The beneficial effects of this invention are as follows: When drying ceramic tile blanks, the door can be opened first, and then the movable rack pre-loaded with ceramic tile blanks can be transferred into the hot air drying chamber and fixed in place by a limiting device to prevent it from moving and to align it with the lifting plate above it. Next, the single-rod hydraulic cylinder is operated to extend its piston rod, which drives the corresponding lifting plate to move down as a whole until the air duct on the lifting plate is fitted into place around the movable rack. Afterwards, the door is closed and the hot air blower and blower are operated. The hot air blower produces hot air, which is then sent to the main air inlet duct, branched through the corresponding air inlet ducts and hoses to the corresponding lifting plates. From there, the air is further distributed into individual ducts and finally sprayed out through nozzles on the ducts. Because the ducts on the lifting plates are evenly distributed around the movable rack, the hot air is evenly distributed to the ceramic tile blanks on the rack, achieving more uniform and effective hot air drying. This ensures consistent drying levels across different racks within the same timeframe, resulting in higher overall drying quality and better facilitating subsequent ceramic tile processing. After drying, the single-rod hydraulic cylinder is operated again, retracting its piston rod and raising the lifting plates until the ducts are above the movable rack. The door is then opened, the movable rack is released from its fixation, and removed from the hot air drying chamber for subsequent processes. In addition, the detachable connection between the lifting plate and the piston rod of the corresponding single-rod hydraulic cylinder, and the connection of the hose to the lifting plate via a quick connector, facilitates the disassembly and replacement of the lifting plate with an adaptable air duct when the size of the movable material rack changes. This allows the equipment to meet the needs of various movable material racks of different sizes, making it more versatile, flexible, convenient, and practical. Attached Figure Description

Detailed Implementation

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 13 As shown, a ceramic tile blank uniform drying device includes a hot air blower 1, a blower 2, a hot air drying chamber 3, and several movable material racks 4. The front of the hot air drying chamber 3 is open and connected to a door 5 that can be opened and closed, and an air inlet duct 6 is fixed on the top. The air outlet of the hot air blower 1 is connected to the air inlet of the blower 2, and the air outlet of the blower 2 is connected to one end of the air inlet duct 6. The bottom of the main air inlet pipe 6 is fixedly connected to several air inlet branch pipes 7 distributed at intervals along its axial direction. The air inlet branch pipes 7 extend into the hot air drying chamber 3 and are fixedly connected to hoses 8. A single-rod hydraulic cylinder 9 is fixedly installed on the top of the hot air drying chamber 3 on one side of the air inlet branch pipe 7. The piston rod of the single-rod hydraulic cylinder 9 faces downward and is detachably connected to a hollow lifting plate 10. The top of the lifting plate 10 is connected to the adjacent hoses 8 through a quick connector 11. Several inverted L-shaped air ducts 12 are fixedly connected to the front, back, left, and right sides. Several nozzles 13 are provided on the inner side of the vertical part of the air duct 12. The movable material rack 4 is located below the lifting plate 10 and is fixed by a limiting device. The air duct 12 is located on the periphery of the corresponding movable material rack 4. When drying the ceramic tile blanks, first open the door 5, then transfer the movable rack 4, pre-loaded with ceramic tile blanks, into the hot air drying chamber 3 and fix it in place using a limiting device to prevent movement and align it with the lifting plate 10 above it. Next, operate the single-rod hydraulic cylinder 9 to extend its piston rod, which will drive the corresponding lifting plate 10 to move downwards until the air duct 12 on the lifting plate 10 is fitted into place around the movable rack 4. Afterwards, close door 5 and run hot air blower 1 and blower 2. Hot air blower 1 produces hot air, and blower 2 sends the hot air produced by hot air blower 1 to the main air inlet duct 6, then through the corresponding air inlet branch duct 7 and hose 8 to the corresponding lifting plate 10, and then through the corresponding lifting plate 10 to the corresponding air duct 12. Finally, it is sprayed out through the nozzle 13 on the corresponding air duct 12. Since the air duct 12 on the corresponding lifting plate 10 is evenly distributed around the movable material rack 4, the hot air can also be evenly blown from the periphery to the tile blanks on the movable material rack 4. This can achieve a more uniform and effective hot air drying treatment for the tile blanks on the movable material rack 4, so that the drying degree of the tile blanks on different movable material racks 4 is consistent at the same time, the overall drying quality is higher, and it is more conducive to the subsequent production and processing of tiles. After drying is complete, the single-rod hydraulic cylinder 9 is operated again to retract its piston rod, driving the lifting plate 10 upward until the air duct 12 rises above the movable material rack 4. Then, the door 5 is opened, the movable material rack 4 is released from its fixation, and it is moved out of the hot air drying chamber 3 to the subsequent process. Furthermore, the detachable connection between the lifting plate 10 and the piston rod of the corresponding single-rod hydraulic cylinder 9, and the connection between the hose 8 and the lifting plate 10 via a quick connector 11, facilitates the replacement of the lifting plate 10 with a suitable air duct 12 when the size of the movable material rack 4 changes. This allows the equipment to accommodate various sizes of movable material racks 4, making it widely applicable, more flexible and convenient to use, and more practical. Both the hot air blower 1 and the blower 2 can utilize existing technology. The hot air blower 1 is the preferred product for upgrading modern industrial heat sources and is the optimal hot air source configuration for automated machinery such as hot air conveying furnaces, drying furnaces, ovens, and packaging machines.

[0016] In this embodiment, a support base 14 is fixedly connected to the bottom end of the piston rod of the single-rod hydraulic cylinder 9. A double-rod hydraulic cylinder 15 is fixedly mounted through the support base 14. Both piston rods of the double-rod hydraulic cylinder 15 are fixedly connected to rectangular limiting frames 16. A mounting base 17 is fixedly mounted at the bottom of the support base 14. A positioning groove 18 is opened at the bottom of the mounting base 17. A positioning block 19 is fixedly connected to the top of the lifting plate 10. The positioning block 19 is inserted into the corresponding positioning groove 18. The limiting frames 16 are fitted on the left and right sides of the mounting base 17 and the positioning blocks 19. This allows the lifting plate 10 to be replaced when it needs to be replaced. In the stopped state, the connection between the lifting plate 10 and the corresponding hose 8 can be disconnected first using the quick connector 11. Then, the double-rod hydraulic cylinder 15 can be operated to extend its two piston rods, causing the corresponding limiting frames 16 to move away from the mounting base 17. This releases the limiting of the positioning blocks 19. Then, the positioning blocks 19 can be pulled out to remove the original lifting plate 10. Next, take a new, compatible lifting plate 10, align the positioning block 19 on it with the corresponding positioning slot 18, and insert it into place. Then, operate the double-rod hydraulic cylinder 15 to retract its two piston rods, driving the two limit frames 16 closer to the mounting base 17 until the limit frames 16 are fitted onto the mounting base 17 and the left and right sides of the positioning block 19, thus fixing the positioning block 19 in place. This completes the fixed installation of the new lifting plate 10. Then, use the quick connector 11 to connect the corresponding hose 8 to the lifting plate 10 for continued use. This allows for flexible and convenient disassembly and replacement of the lifting plate 10, facilitating the replacement of the lifting plate 10 with the compatible air duct 12 when the size of the movable rack 4 changes. This makes the equipment compatible with various sizes of movable racks 4, with a wide range of applications, making it more flexible, convenient, and practical.

[0017] In this embodiment, the limiting frame 16 is adapted to the mounting base 17, and the positioning block 19 is adapted to the positioning groove 18 to ensure the smooth fixed installation of the lifting plate 10.

[0018] In this embodiment, the movable material rack 4 includes a base 20, with casters 21 installed at each of the four corners of the base 20. Several perforated plates 22 are arranged vertically at intervals on the top of the base 20. The perforated plates 22 are fixedly connected to each other and to the base 20 via support pillars 23 at the four corners. In use, the ceramic tile blanks are simply placed orderly onto the perforated plates 22, and then the casters 21 are used to move and transport the entire movable material rack 4. The through holes on the perforated plates 22 ensure air circulation during drying, accelerate the evaporation and discharge of moisture from the ceramic tile blanks, and further improve drying quality.

[0019] In this embodiment, the limiting device includes a baffle 24 fixedly connected to the rear side of the base 20, a rectangular positioning seat 25 fixedly provided on the rear side of the baffle 24, a rectangular locking seat 26 rotatably connected to the rear side of the positioning seat 25, a back plate 27 fixedly provided in the hot air drying chamber 3 on the rear side of the base 20, a through groove 28 provided on the back plate 27, the baffle 24 abutting against the front side of the back plate 27, the positioning seat 25 being inserted into the through groove 28, the locking seat 26 penetrating through the corresponding through groove 28 and its front side being flush with the rear side of the back plate 27, and the locking seat 26 abutting against the rear side of the back plate 27 after rotating 90 degrees. During actual drying, after moving the movable rack 4 into the hot air drying chamber 3, it needs to be moved, adjusted, and fixed in place. Specifically: First, move the movable rack 4 towards the corresponding back plate 27, aligning the locking seat 26 and positioning seat 25 with the through slot 28 on the corresponding back plate 27, until the baffle 24 is pressed against the front side of the back plate 27. At this point, the positioning seat 25 can be inserted into the through slot 28 of the corresponding back plate 27, while the locking seat 26 passes through the corresponding through slot 28 to the rear side of the back plate 27, thus completing the positioning of the movable rack 4. Next, rotate the locking seat 26 90 degrees so that it is perpendicular to the corresponding through slot 28, pressing it against the rear side of the back plate 27, thereby locking and limiting the movable rack 4. In this way, the movable rack 4 can be quickly positioned and fixed, ensuring that the corresponding air duct 12 can smoothly descend and distribute to the periphery of the movable rack 4, thus achieving uniform drying processing. When the movable rack 4 needs to be removed after drying, simply rotate the locking seat 26 90 degrees again to align it with the corresponding through slot 28, and then move the movable rack 4 forward. The operation is simple and more practical.

[0020] In this embodiment, both the positioning seat 25 and the locking seat 26 are adapted to the corresponding through slot 28 to ensure the smooth positioning and fixation of the movable material rack 4.

[0021] In this embodiment, a traction ring 29 is fixed on the front side of the base 20 to facilitate the traction control of the movable material rack 4 for movement.

[0022] In this embodiment, the top of the hot air drying chamber 3 is connected to an exhaust pipe 30 to exhaust excess air.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
