[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: an intelligent temperature-controlled energy-saving kiln, comprising: a kiln body 1; a side fixed support box 2 installed on one side of the kiln body 1 by bolts; a bracket 3 slidably disposed inside the kiln body 1, with a kiln door 5 fixedly connected to one side of the bracket 3 to cooperate with the kiln body 1, the kiln door 5 being slidably connected to the side fixed support box 2; an inner fixed support plate 6 equidistantly fixed to the inner side of the kiln body 1, with multiple bottom gas conduits 7 equidistantly fixed to the bottom of the inner fixed support plate 6, and multiple first combustion nozzles 8 disposed at the bottom of the bottom gas conduits 7; and side gas conduits 10 symmetrically and equidistantly fixed to the inner side of the kiln body 1, with multiple second combustion nozzles 11 equidistantly disposed on the inner side of the side gas conduits 10.

[0024] It should be noted that in this embodiment, the ceramic blank to be sintered is placed on the support 3 and centrally controlled by an external controller. The output of the motor 18 drives the adjusting screw 19 to rotate, which in turn drives the outer sliding block 20 to slide on the side fixed support box 2. The sliding block 20 drives the furnace door 5 to move, which in turn drives the support 3 to move synchronously. The furnace door 5 drives multiple guide wheels 4 at the bottom to move, and the guide wheels 4 roll inside the kiln body 1 to facilitate the extension and entry of the support 3. An external gas supply device is connected through the air inlet pipe 16, and an electrically controlled valve is installed on the air inlet pipe 16 to control the amount of gas entering the air inlet pipe 16. The gas enters the bottom gas duct 7 through the pipeline and is sprayed out through the first combustion nozzle 8 at the bottom of the bottom gas duct 7. The gas is ignited by the first combustion nozzle 8. The gas enters the main gas duct 17 through the pipeline, and then enters each side gas duct 10 through the main gas duct 17. The gas is then ignited by multiple second combustion nozzles inside the side gas duct 10. The combustion nozzle 11 and multiple No. 1 combustion nozzles 8 at the bottom of the bottom gas duct 7 spray fire. The combustion nozzles include ignition structures to sinter the billet. The temperature inside the kiln body 1 is monitored by thermocouple 14. The air intake flow is controlled by an electrically controlled valve installed on the air intake pipe 16. Hot water is injected into one end of the No. 1 S-type hot water exchange pipe 9 and the No. 2 S-type hot water exchange pipe 13. The water in the No. 1 S-type hot water exchange pipe 9 and the No. 2 S-type hot water exchange pipe 13 vents the water entering the kiln body 1. Heat exchange treatment is performed by rotating the adjusting screw 19 through the output end of the motor 18. When the adjusting screw 19 rotates, it drives the outer movable slider 20 to move. The movable slider 20 drives the furnace door 5 and the support 3 to move. The support 3 drives the bottom guide wheel 4 to roll inside the kiln body 1, which facilitates the removal of the sintered ceramics inside the support 3. Flame-retardant and high-temperature resistant bellows cloth is fixedly installed between the two sides of the movable slider 20 and the side fixed support box 2 with bolts to protect the inside of the side fixed support box 2.

[0025] In one embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, it also includes a No. 1 S-type hot water exchange pipe 9 and a No. 2 S-type hot water exchange pipe 13. The bottom of the inner fixed support plate 6 is fixedly connected to the No. 1 S-type hot water exchange pipe 9. Multiple side fixed brackets 12 are fixedly connected at equal intervals on the inner side of the side gas conduit 10. The No. 2 S-type hot water exchange pipe 13 is fixedly connected to the inner side of the side fixed bracket 12. Water temperature sensors 22 are installed on both the No. 1 S-type hot water exchange pipe 9 and the No. 2 S-type hot water exchange pipe 13. The water temperature sensors 22 are located outside the kiln body 1.

[0026] It should be noted that, in this embodiment, hot water is injected through one end of the No. 1 S-type hot water exchange pipe 9 and the No. 2 S-type hot water exchange pipe 13. The hot water injected through the No. 1 S-type hot water exchange pipe 9 and the No. 2 S-type hot water exchange pipe 13 performs heat exchange treatment inside the kiln body 1. The heat exchange outlet water temperature of the No. 1 S-type hot water exchange pipe 9 and the No. 2 S-type hot water exchange pipe 13 is monitored and processed by the water temperature sensor 22.

[0027] In one embodiment, such as Figure 4 As shown, a gas supply box 15 is fixedly connected to one side of the kiln body 1, and an air inlet pipe 16 is fixedly connected to one side of the gas supply box 15. A main gas conduit 17 is symmetrically fixedly connected to the inner side of the kiln body 1. The main gas conduit 17 is connected to the side gas conduit 10 through a pipe. The bottom gas conduit 7 and the main gas conduit 17 are both connected to the gas supply box 15 through a pipe.

[0028] It should be noted that in this embodiment, gas is injected into the gas supply box 15 through the air inlet pipe 16. The gas in the gas supply box 15 enters the main gas conduit 17 and the bottom gas conduit 7 through the pipes, and is sprayed out through the first combustion nozzle 8 and the second combustion nozzle 11 to complete the sintering treatment of the billet.

[0029] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, an adjusting screw 19 is rotatably installed inside the side fixed support box 2. A movable slider 20 is installed on the adjusting screw 19. The movable slider 20 is slidably connected to the side fixed support box 2. A limit rod 21 is symmetrically slidably installed inside the movable slider 20. The limit rod 21 is fixedly connected to the side fixed support box 2. The top of the movable slider 20 is fixedly connected to the furnace door 5. A motor 18 is installed on one side of the side fixed support box 2 by bolts. The output end of the motor 18 is fixedly connected to the adjusting screw 19.

[0030] It should be noted that in this embodiment, the output end of the motor 18 drives the adjusting screw 19 to rotate. When the adjusting screw 19 rotates, it drives the outer movable slider 20 to move. The movable slider 20 drives the furnace door 5 to slide on the side fixed support box 2, thereby adjusting the position of the furnace door 5 and the support 3 inside the kiln body 1.

[0031] In one embodiment, such as Figure 1 and Figure 4 As shown, multiple guide wheels 4 are symmetrically installed at the bottom of the bracket 3.

[0032] It should be noted that in this embodiment, the bracket 3 is guided by the guide wheel 4 to facilitate the movement of the bracket 3.

[0033] In one embodiment, such as Figure 4As shown, multiple thermocouples 14 are symmetrically installed on the inner side of the kiln body 1, and an electrically controlled valve is installed on the air inlet pipe 16.

[0034] It should be noted that in this embodiment, the air flow rate of the air inlet pipe 16 is controlled by installing an electrically controlled valve on the air inlet pipe 16, and the temperature inside the kiln body 1 is monitored by a thermocouple 14.
