DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0019] A low temperature frit firing device of this embodiment is shown in the attached Figure 1 and 2 , comprising a frit pool kiln 1, a feeding mechanism 2, a burner 3, a discharging mechanism 4 and a water circulation unit; the frit pool kiln 1 is provided with a combustion channel 111, a melting pool 112 and a discharge channel 113 which are connected in sequence, the discharge channel 113 is provided with a discharge gap 114, the size of which is adjustable, the bottom surface of the melting pool 112 is inclined downward from one end close to the combustion channel 111 to one end close to the discharge channel 113, a liquid level regulating plate 131 is further provided between the end of the melting pool 112 and the discharge channel 113, and the vertical height of the liquid level regulating plate 131 is adjustable, A feed port 116 is also provided on one side of the melting pool 112. The combustion channel 111, the discharge channel 113 and the feed port 116 are all arranged at a height higher than the bottom surface of the melting pool 112. The burner 3 is arranged at one end of the molten block pool kiln 1. The output end of the burner 3 is communicated with the melting pool 112 through the combustion channel 111. The output end of the feeding mechanism 2 corresponds to the feed port 116. The discharge mechanism 4 is arranged below the discharge gap 114. The discharge mechanism 4 is used to quench the flux discharged from the melting pool 112, and continue to lift and transport it to the outside after quenching. The water circulation unit is connected to the discharge mechanism 4.

[0020] Compared with the rotary kiln in the prior art, the low-temperature frit firing device of this embodiment uses a frit pool kiln 1 to fire the flux, which reduces the amount of dust generated during the high-temperature turning process, thereby effectively reducing the pollution to the environment, and at the same time greatly reduces the threat to the health of the operators and improves the working environment; the melting pool 112 kiln is provided with a liquid level adjustment plate 131 and an adjustable discharge gap 114, which realizes more efficient thermal energy utilization and reduces energy waste. The tilting setting of the melting pool 112, the adjustable vertical height of the liquid level adjustment plate 131 and the adjustable size of the discharge gap 114 enable the device to meet more production needs. The operator adjusts the production parameters according to actual needs to meet the production of glass ink fluxes of different specifications and qualities. The device is also provided with a feeding mechanism 2, a burner 3, a discharging mechanism 4 and a water circulation unit, which realizes a fully automated process from raw material feeding to flux quenching and output, reduces manual intervention, improves production efficiency, and ensures the stability of product quality. The quality and performance stability of the produced glass ink flux are ensured by the heat supply of the burner 3 and the quenching treatment provided by the discharging mechanism 4 and the water circulation unit.

[0021] Preferably, the frit pool kiln 1 includes a kiln body 11 and an inclined bottom plate 12 made of high-alumina bricks 115, a combustion channel 111, a melting pool 112 and a discharge channel 113 are formed in the kiln body 11, the inner diameter of the combustion channel 111 gradually increases from one end of the frit pool kiln 1 to the end close to the melting pool 112, the inclined bottom plate 12 is arranged at the bottom of the melting pool 112, so that the bottom of the melting pool 112 forms a bottom surface inclined downward from the end close to the combustion channel 111 to the end close to the discharge channel 113, the inclined bottom plate 12 is paved with electric-fused zirconium corundum bricks, and the bottom of the inclined bottom plate 12 is filled with thermal insulation filler 14, the top of the melting pool 112 and the top of the discharge channel 113 are respectively provided with a first insulation layer 15 and a second insulation layer 16, and the first insulation layer 15 and the second insulation layer 16 are both made of insulation bricks.

[0022] The kiln body 11 is built with high-alumina bricks 115, and the high-alumina bricks 115 have good high-temperature resistance and thermal stability, ensuring that the kiln body 11 maintains structural strength and stability when working in a high-temperature environment for a long time. The inclined bottom plate 12 is paved with fused zirconium corundum bricks, and the wear resistance, corrosion resistance and high-temperature resistance of the fused zirconium corundum bricks can withstand the scouring and corrosion of high-temperature materials in the melting pool 112, thereby extending the service life of the kiln. By setting the inclined bottom plate 12, the bottom of the melting pool 112 is formed into a bottom surface that is inclined downward from one end close to the combustion channel 111 to one end close to the discharge channel 113, so that the high-temperature material can flow naturally and be evenly distributed in the melting pool 112, reducing the retention time of the material in the melting pool 112, improving the melting efficiency, and ensuring that the high-temperature material is fully melted. By filling the bottom of the inclined bottom plate 12 with a heat insulating filler 14, not only the heat loss of the melting pool 112 is reduced and the thermal efficiency of the kiln is improved, but also the installation of the inclined bottom plate 12 is facilitated. During installation, a plane inclined downward is formed at the bottom of the melting pool 112 by laying the heat insulating filler 14, and then the fused zirconium corundum bricks are hoisted on the plane to form the inclined bottom plate 12. The first insulation layer 15 and the second insulation layer 16 made of insulation bricks are respectively arranged on the top of the melting pool 112 and the top of the discharge channel 113, wherein the formation of the first insulation layer 15 can reduce the heat loss at the top of the melting pool 112, so that the temperature in the melting pool 112 remains stable, which is conducive to the full melting of the flux. The formation of the second insulation layer 16 can reduce the heat loss in the discharge channel 113, ensuring that the flux maintains an appropriate temperature during the discharge process. By setting the inner diameter of the combustion channel 111 to gradually increase from one end of the frit pool kiln 1 to the end close to the melting pool 112, the combustion gas gradually expands in the combustion channel 111, mixes more fully with the air, burns more completely, and improves the combustion efficiency.

[0023] Preferably, the sinter pool kiln 1 also includes a discharge assembly, which includes a discharge valve port 171, a lifting valve core 172 and a first lifting component. The discharge valve port 171 is vertically arranged in the discharge channel 113, and the opening area of ​​the discharge valve port 171 gradually decreases from top to bottom. The first lifting component is arranged in the discharge channel 113, and the lifting valve core 172 is arranged at the lifting end of the first lifting component and is arranged opposite to the discharge valve port 171 up and down. A discharge gap 114 is formed between the lifting valve core 172 and the inner side of the discharge valve port 171. When the first lifting component drives the lifting valve core 172 to move up and down, the discharge gap 114 increases or decreases.

[0024] By arranging the discharge valve opening 171 vertically in the discharge channel 113 and arranging the opening area to gradually decrease from top to bottom, the high-temperature material can be subjected to gradually increasing resistance during the discharge process, so that it can flow out more smoothly, thereby improving the stability of the discharge.

[0025] By setting a lifting valve core 172 at the lifting end of the first lifting component, the lifting valve core 172 and the discharge valve port 171 are arranged opposite to each other up and down, and the shape and size of the lifting valve core 172 match the discharge valve port 171, so that the lifting valve core 172 moves up and down under the drive of the first lifting component, thereby adjusting the gap between the lifting valve core 172 and the discharge valve port 171, that is, the size of the discharge gap 114, so that the operator or the automation program can flexibly adjust the discharge gap 114 according to production requirements to achieve continuous and stable discharge of the flux. When the discharge amount needs to be increased, the lifting valve core 172 can be raised to increase the discharge gap 114; when the discharge amount needs to be reduced or the discharge needs to be stopped, the lifting valve core 172 can be lowered to reduce or close the discharge gap 114, thereby achieving automatic control of the discharge amount.

[0026] Preferably, the melt pool kiln 1 also includes a liquid level adjusting component, which includes a liquid level adjusting plate 131, a second lifting component and an infrared sensor. A rear pool wall 117 is provided between the melting pool 112 and the discharge channel 113. One side of the liquid level adjusting plate 131 is in contact with the rear pool wall 117. The second lifting component is provided above the melting pool 112. The liquid level adjusting plate 131 is provided at the lifting end of the second lifting component. A horizontal pool bottom section is also provided at the bottom of the melting pool 112. The horizontal pool bottom section is connected to the end of the inclined bottom plate 12. The liquid level adjusting plate 131 and the horizontal pool bottom section are arranged opposite to each other up and down. The second lifting component is used to drive the liquid level adjusting plate 131 to move up and down to adjust the height of the liquid level adjusting plate 131. The infrared sensor is provided above the discharge channel 113. The infrared sensor is used to detect the liquid level height of the discharge channel 113.

[0027] By arranging the liquid level adjustment plate 131 at the lifting end of the second lifting component, the height of the liquid level adjustment plate 131 is adjusted under the drive of the second lifting component, thereby controlling the liquid level in the melting pool 112, thereby ensuring that the flux is discharged in time after reaching the ideal state. By arranging a horizontal pool bottom section connected to the end of the inclined bottom plate 12 at the bottom of the melting pool 112, the liquid level adjustment plate 131 can fit with the bottom of the melting pool 112 when it is in a low position. By arranging an infrared sensor above the discharge channel 113, the liquid level of the discharge channel 113 is detected in real time, so that the liquid level of the flux in the melting pool 112 is obtained in real time, which is convenient for adjusting the height of the liquid level adjustment plate 131. During the melting process, the lifting stroke of the second lifting component is controlled by the feedback of the infrared sensor on the liquid level of the discharge channel 113, thereby adjusting the height of the liquid level adjustment plate 131. When the liquid level is too high, the second lifting component is driven to rise, so that the liquid level adjusting plate 131 rises, thereby reducing the flux in the melting pool 112 from flowing into the discharge channel 113; and when the liquid level is too low, the second lifting component is driven to descend, so that the liquid level adjusting plate 131 descends, thereby increasing the flux in the melting pool 112 from flowing into the discharge channel 113, thereby realizing feedback regulation and ensuring that the liquid level in the melting pool 112 is always maintained within the set target range.

[0028] Preferably, refer to the attached Figure 3 and 4 The discharging mechanism 4 includes a quenching pool 41, a discharging elevator 42 and a discharging bin 43. The quenching pool 41 includes a quenching bucket 411 and a quenching water tank 412. The quenching bucket 411 is arranged below the discharging port. One side of the quenching bucket 411 is connected to the quenching water tank 412. The feeding end of the discharging elevator 42 extends into the quenching water tank 412. The discharging end of the elevator is connected to the discharging bin 43. A plurality of nozzles 413 are arranged on the top of the quenching bucket 411. The return water end of the water circulation unit is connected to the bottom of the quenching water tank 412. The water outlet end of the water circulation unit is connected to a plurality of nozzles 413.

[0029] The quenching bucket 411 is arranged below the discharge port, and is used to receive the high-temperature flux discharged from the melting pool 112, and under the guidance of the quenching bucket 411, the flux is directed to the quenching water tank 412, so that the flux is fully in contact with the cooling water, providing a continuous cooling effect for the flux. By arranging a plurality of nozzles 413 at the top of the quenching bucket 411, when discharging, the nozzles 413 spray the cooling water evenly on the flux, achieving a rapid and uniform cooling effect, and also realizing the circulation of the cooling water. By extending the feed end of the discharge hoist 42 into the quenching water tank 412, the cooled flux in the quenching water tank 412 can be lifted to the discharge bin 43 connected to the discharge end of the discharge hoist 42, and the cooled flux can be sent to the discharge bin 43 for storage or further processing.

[0030] Preferably, the discharge elevator 42 includes a lifting motor 421, a driving wheel 422, a driven wheel 423, a conveyor belt 424 and a plurality of lifting plates 425. The driving wheel and the driven wheel 423 are arranged up and down, the driven wheel 423 is arranged in the quenching water tank 412, the rotating shaft end of the lifting motor 421 is connected to the driving wheel 422, the conveyor belt 424 is meshed with the driving wheel 422 and the driven wheel 423, and the plurality of lifting plates 425 are arranged on the outside of the conveyor belt 424. When the driving wheel 422 is driven to rotate by the conveyor belt 424, the plurality of lifting plates 425 are driven to pass through the bottom end of the quenching bucket 411 from bottom to top one by one. The bottom of the quenching bucket 411 is also provided with a first guide plate 414 which is inclined. The bottom end of the first guide plate 414 extends to a position close to the lifting plate 425. A filter plate 428 is provided in the quenching box.

[0031] The lifting motor 421 is used as the power source of the discharge elevator 42. The conveyor belt 424 is meshed between the driving wheel 422 and the driven wheel 423 to form a closed loop movement. The conveyor belt 424 near the quenching bucket 411 side is lifted, and the conveyor belt 424 near the discharge bin 43 side is lowered. A plurality of lifting plates 425 are provided on the outside of the conveyor belt 424 for carrying and conveying the flux. When the conveyor belt 424 moves, the lifting plates 425 will pass through the bottom of the quenching bucket 411 from bottom to top one by one, lift the cooled flux and convey it to the discharge bin 43. The bottom of the quenching bucket 411 is provided with an inclined setting so that the flux in the quenching bucket 411 can slide into the lifting plate 425. The filter plate 428 is provided in the quenching water tank 412 and is located on the movement track of the lifting plate 425. It contacts the outer side of the lifting plate 425 , and limits the flux in the quenching water tank 412 , so that the flux is always located on the movement track of the lifting plate 425 , avoiding falling into the quenching water tank 412 , ensuring that the flux can be picked up by the lifting plate 425 and put into the discharge bin 43 .

[0032] Preferably, the bottom of the lifting plate 425 is provided with an arc section 426 which gradually transitions upward from the end close to the driven wheel 423 to the end close to the quenching bucket 411, and a plurality of drainage holes 427 are opened at the bottom of the lifting plate 425.

[0033] The bottom of the lifting plate 425 is provided with an arc segment 426 that gradually transitions upward from the end close to the driven wheel 423 to the end close to the quenching bucket 411. This not only enables the lifting plate 425 to better adapt to the shape and weight distribution of the molten block when receiving the molten block, ensuring that the molten block is stably placed on the lifting plate 425, but also uses the arc segments 426 in the upper and lower adjacent lifting plates 425 to slide the flux to the second guide plate 431 during discharge (the arc segments 426 face upward and the opening of the lifting plate 425 faces downward during discharge), which facilitates the discharge of the flux.

The second molten pool thermocouple is arranged near the discharge channel 113 of the molten pool 112, and is used to detect and monitor the temperature at the end of the molten pool 112. The temperature data collected by the second molten pool thermocouple is used to control the temperature gradient of the molten pool 112 to maintain the stability of the temperature in the molten pool 112. The thermocouple at the discharge end is arranged in the discharge channel 113, and is used to detect the temperature of the flux before it is discharged from the kiln, and ensure that the molten block enters the subsequent cooling and discharging process at an appropriate temperature.

[0035] By real-time data collection of the thermocouple at the heating end, the first molten pool thermocouple, the second molten pool thermocouple and the discharge end thermocouple, the temperature distribution in the molten block pool kiln 1 can be monitored and controlled. According to the feedback data of each thermocouple, the output of the burner 3 and the water temperature of the quenching pool 41 and other parameters can be adjusted in real time to ensure that the flux can maintain the temperature required by the process during the entire firing process.

Through the feedback of the inlet water temperature sensor, the cooling capacity of the water circulation unit can be adjusted in time to ensure that the water temperature of the cooling water remains within the set range. By arranging the return water temperature sensor at the beginning of the nozzle 413, it is used to collect the actual water temperature of the cooling water sprayed by the nozzle 413. Through the feedback of the return water temperature sensor, the cooling capacity of the water circulation unit can be further adjusted to achieve the best cooling effect. By arranging the infrared temperature sensor at the bottom of the first guide plate 414, it is used to collect the temperature of the first guide plate 414, indirectly reflecting the actual temperature of the flux during the quenching process. Therefore, through the arrangement of the inlet water temperature sensor, the return water temperature sensor and the infrared temperature sensor, the water temperature, cooling effect and melting block temperature of the quenching pool 41 can be monitored and controlled. According to the feedback data from each sensor, the preset algorithm is used to adjust the parameters such as the cooling capacity, water output and the water spraying mode of the water circulation unit in real time to ensure that the flux is cooled evenly and appropriately during the quenching process.

[0038] Preferably, the feeding mechanism 2 includes a feeding motor 21, a feeding barrel 22, a feeding screw and a heating coil 23. The feeding motor 21 is arranged at one end of the feeding barrel 22, and the other end of the feeding barrel 22 corresponds to the feed port 116. The feeding screw is arranged in the feeding barrel 22, and one end of the feeding screw is connected to the rotating shaft end of the feeding motor 21. The heating coil 23 covers the outside of the feeding barrel 22. A centrifugal fan 24 is provided at the bottom of the heating coil 23, and a radially arranged feed box is also provided on the feeding barrel 22. The feeding mechanism 2 of this embodiment uses a feeding screw to feed the flux raw material. When the feeding motor 21 is started, the feeding screw starts to rotate, pushing the flux raw material entering from the feed box at one end of the feeding barrel 22 to the feed port 116 of the frit pool kiln 1. During the pushing process, the flux in the feeding barrel 22 is preheated by the heating ring 23, and the heating process is accelerated by the centrifugal fan 24 by forced convection, ensuring that the raw material reaches the preset temperature during the conveying process. When the raw materials are pushed to the end of the feeding barrel 22, they enter the frit pool kiln 1 through the feed port 116 for melting and firing.
