[0026] This specific embodiment is a glass-ceramic tempering furnace inner liner structure, the schematic diagram of which is shown below. Figure 1-6 As shown, the system includes a frame 1, a control panel 2 located at the upper center of one side wall of the frame 1, protective structures 3 located at the center of both the front and rear faces of the frame 1, an inner liner disassembly and installation structure 8 fitted on the inner side wall of the frame 1, and an air intake structure 4 located at the center of both the upper and lower faces of the frame 1.

[0027] First, in this embodiment, the specific structure of the inner liner disassembly and installation structure 8 is as follows:

[0028] The inner liner disassembly and installation structure 8 includes a second inner liner 806, which is fitted onto the inner wall of the frame 1. A first inner liner 805 is fitted into the center of the second inner liner 806. A cavity 6 is provided between the second inner liner 806 and the first inner liner 805. Electric heaters 7 are provided at the upper and lower center of the cavity 6 and at the center of both side walls. Multiple through holes 804 are arranged in a rectangular pattern at the center of the upper and lower inner walls of the first inner liner 805. The first inner liner 805 and the second inner liner 806 form a double-layer structure. The electric heaters 7 in the cavity 6 are the core heating components. When working, the electric heaters 7 are energized and generate heat. The heat generated is continuously transferred to the internal space of the first inner liner 805 through the rectangular through holes 804. This internal space is where the glass ceramic is placed for tempering. This heating method meets the temperature conditions required for tempering the glass ceramic.

[0029] Furthermore, sliding grooves 801 are provided on both sides of the center of the upper end face and the center of both sides of the center of the lower end face of the second inner liner 806. Sliding blocks 802 are provided on both sides of the center of the upper inner wall and the center of the lower inner wall of the frame 1. Limiting blocks 803 are rotatably connected to both sides of the upper rear end face of the frame 1. Two limiting blocks 803 are movably connected to the rear end face of the second inner liner 806. Four sliding blocks 802 are slidably connected to the center of the four sliding grooves 801. The design of the sliding blocks 802 on the frame 1 and the sliding grooves 801 on the second inner liner 806 is for… The installation and removal of the second inner liner 806 are facilitated. During installation or removal, the second inner liner 806 can be operated along the inner wall of the frame 1 and along the sliding trajectory of the sliding block 802 in the sliding groove 801. After the second inner liner 806 is installed, it plays an important role by rotating the limiting block 803 to lock it in place at the rear end face of the second inner liner 806, which can effectively limit the sliding of the second inner liner 806, thereby ensuring the stability of the second inner liner 806 after installation and ensuring that the inner liner structure will not be displaced or shaken during equipment operation, thus affecting the heating effect and equipment safety.

[0030] Then, the two protective structures 3 include two lifting frames 301, which are respectively located at the center of the front face and the center of the rear face of the frame 1. Each of the two lifting frames 301 has a sliding groove 302 at the center of one side wall. Each of the two lifting frames 301 has a servo motor 303 at the center of the upper face. The output ends of the two servo motors 303 pass through the upper face of the two lifting frames 301 and the upper face of the two sliding grooves 302 and are connected to the inside of the two sliding grooves 302. Each end is fixedly connected to a lead screw 304. By starting the servo motor 303, the lead screw 304 is driven to rotate. Due to the threaded engagement between the lead screw 304 and the lifting plate 305, the rotating lead screw 304 will drive the lifting plate 305 to slide downward in the sliding groove 302 until the blocking pad 306 blocks the material port of the frame 1.

[0031] Furthermore, both lead screws 304 are threaded with lifting plates 305 on their outer side walls. The center of the rear end face of the front lifting plate 305 and the center of the front end face of the rear lifting plate 305 are both provided with blocking pads 306. When feeding or discharging is required, the servo motor 303 rotates in reverse, and the lead screws 304 also rotate in reverse, causing the lifting plates 305 to slide upward in the slide groove 302, so that the blocking pads 306 leave the material outlet position and open the channel. This can protect the operators from high temperature and possible dangers during equipment operation, and also prevent unnecessary heat loss from the furnace, thereby improving energy utilization efficiency.

[0032] The two air intake structures 4 include two air intake frames 401, which are respectively located at the center of the upper end face and the center of the lower end face of the frame 1. Two sliding frames 402 are arranged vertically at the center of the upper air intake frame 401 and the center of the lower air intake frame 401. The four sliding frames 402 are slidably connected to the lifting box 403 at their center. By starting the fan 406, a strong suction force is generated to draw outside air into the air intake structure 4. The air first passes through the filter screen 404. This component can effectively intercept larger impurity particles in the air and prevent these impurities from entering the furnace and affecting the quality of the glass ceramic.

[0033] Secondly, a fan 406 is installed at both the lower center of the upper air intake frame 401 and the upper center of the lower air intake frame 401. Adsorption cotton 405 is installed inside the two carrying boxes 403 at the upper and lower ends of the lower air intake frame 406. A filter screen 404 is installed at the center of the two carrying boxes 403 at the upper and lower ends of the upper and lower adsorption cotton 405. The four filters 404 pass through the inner sidewalls of the four sliding frames 402 and the inner sidewalls of the two air intake frames 401 respectively. The side wall leads to one side wall of the two air inlet racks 401. After preliminary filtration, the air continues to move forward and enters the adsorption cotton 405 area. The adsorption cotton 405 further plays its role, adsorbing even smaller dust and impurities in the air, so that the air entering the furnace is deeply purified. The purified air is finally blown into the first inner liner 805 by the fan 406. It can regulate the flow of gas and temperature distribution in the furnace, allowing the glass ceramics to be tempered in a more uniform atmosphere and temperature environment, which is conducive to improving the consistency of product quality.

[0034] Finally, material inlets are provided at the center of both the front and rear faces of frame 1, and support blocks 5 are provided at the four opposite corners of the lower face of frame 1. These support blocks 5 bear the weight of the entire device, ensuring its stable placement in the workplace. The support blocks 5 ensure that the equipment will not shake or tilt during operation, providing a solid foundation for its normal operation. The material inlets at the center of the front and rear faces of frame 1 serve as channels for the entry of glass ceramic raw materials and the removal of tempered products. Through coordinated operation with the protective structure 3, the material inlets are opened and closed at appropriate times, allowing the feeding and discharging of glass ceramics to proceed smoothly. This, in conjunction with the air intake structure 4 and the heating of the inner liner, enables the normal operation of the device.

[0035] When using the device of this technical solution, the operator issues a command through the control panel 2 to start the servo motor 303 to drive the lead screw 304 to rotate. Since there is a threaded connection between the lead screw 304 and the lifting plate 305, the rotation of the lead screw 304 causes the lifting plate 305 to slide upward along the slide groove 302. The blocking pad 306 installed on the lifting plate 305 rises accordingly, moving away from the material inlet positions of the front and rear faces of the frame 1, thereby opening the feeding channel. The glass ceramic raw material is smoothly fed into the first inner liner 805 through the opened front or rear material inlet. After the raw material is fed in, the operator issues a command through the control panel 2 again to reverse the servo motor 303, driving the lead screw 304 to rotate in the opposite direction. At this time, the lifting plate 305 slides downward along the slide groove 302, and the blocking pad 306 gradually descends until it completely blocks the material inlet of the frame 1, resealing the equipment to prevent heat loss and foreign objects from entering the furnace.

[0036] The operator sets the appropriate heating temperature and heating time on the control panel 2. This instruction is transmitted through the circuit to the control system connected to the electric heater 7, which precisely adjusts the power of the electric heater 7. The electric heater 7 starts working according to the set parameters, generating heat. The heat is evenly transferred to the glass ceramic inside the first inner liner 805 through the rectangularly arranged through holes 804 on the first inner liner 805. At the same time, the suction generated by the fan 406 draws outside air into the air intake frame 401. The air first passes through the filter screen 404 in the sliding frame 402, which can filter out larger dust and impurity particles in the air. Then the air passes through the absorbent cotton 405 in the lifting box 403, which further absorbs fine dust and harmful substances in the air. The purified air is blown into the first inner liner 805 by the fan 406. Through the appropriate air volume adjustment of the fan 406 and the design of the air intake position, the gas in the furnace is evenly distributed, creating an atmosphere conducive to the uniform tempering of the glass ceramic.

[0037] Throughout the heating and tempering process, the temperature field and atmosphere field inside the furnace work together to promote the transformation of the internal microstructure of the glass ceramic and optimize the stress distribution, thereby achieving a good tempering effect. When the set heating time ends and the glass ceramic completes the tempering process, the operator restarts the servo motor 303 through the control panel 2 to drive the lead screw 304 to rotate. The lifting plate 305 slides upward along the slide groove 302, and the blocking pad 306 leaves the material port, opening the discharge channel. After the product is discharged, the operator controls the servo motor 303 to reverse through the control panel 2, the lead screw 304 rotates in the opposite direction, the lifting plate 305 slides downward along the slide groove 302, and the blocking pad 306 re-blocks the material port of the frame 1, restoring the closed state of the equipment.

[0038] Furthermore, the cooperative design of the sliding block 802 on the frame 1 and the sliding groove 801 on the second inner liner 806 facilitates the installation and disassembly of the second inner liner 806. During installation or disassembly, the second inner liner 806 can operate along the inner wall of the frame 1, following the trajectory of the sliding block 802 sliding in the sliding groove 801. This plays an important role after the second inner liner 806 is installed. Rotating the limiting block 803 to lock it in place at the rear end face of the second inner liner 806 effectively restricts the sliding of the second inner liner 806, thereby ensuring the stability of the second inner liner 806 after installation and ensuring that the inner liner structure will not shift or shake during equipment operation, affecting the heating effect and equipment safety.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
