During the production of insulators, a kiln is required for processing. Currently, there are many types of kilns, and the automatic pulse kiln is one of them.

Some kilns generate heat by energizing heating elements such as resistance wires and silicon carbide rods, and then preheat the air, materials, or specific parts of the kiln.

[0020] The following is a further detailed description of the present invention with reference to the Figures 1-7 accompanying drawings.

[0021] Please refer to Figures 1-7 , an automatic pulse kiln firing device for insulators, which includes a main body module 100, a preheating module 200, and a spraying module 300. The main body module 100 includes a conveying device 110. A preheating box 130 and a kiln body 120 are connected to the top of the conveying device 110. The kiln body 120 is connected to the preheating box 130. The preheating module 200 includes a heat conduction oil tank 210 fixedly connected to the top of the preheating box 130. A smoke exhaust pipe 220 is fixedly connected to the kiln body 120. The smoke exhaust pipe 220 penetrates through the heat conduction oil tank 210. A plurality of heat conduction rings 230 are fixedly connected to the outer surface of the heat conduction oil tank 210. A heat conduction component 240 is arranged between the interior and the top of the preheating box 130. The heat conduction component 240 is connected to the heat conduction oil tank 210. An air supply component 250 is arranged on the inner wall of the preheating box 130. The air supply component 250 is located between the heat conduction component 240 and the inner wall of the preheating box 130. A driving component 260 is arranged on one side of the preheating box 130. A stirring component 270 is arranged inside the heat conduction oil tank 210. Both the stirring component 270 and the air supply component 250 are connected to the driving component 260. The spraying module 300 is connected to the top of the heat conduction oil tank 210.

[0022] During use, the flue gas of the furnace body 120 will be discharged through the exhaust pipe 220. The discharged flue gas conducts heat through the heat conduction ring 230, thereby heating the heat conduction oil inside the heat conduction oil tank 210. When the driving component 260 is turned on, the driving component 260 will drive the stirring component 270, and the stirring component 270 will stir the heat conduction oil, so that the heat conduction oil conducts heat more evenly. When the heat conduction component 240 is turned on to circulate the heat conduction oil, at the same time, the driving component 260 will drive the air supply component 250, and the air supply component 250 will supply air to the heat conduction component 240 from multiple directions, so that the insulator reaches the preheating effect when passing through the inside of the heat conduction component 240. The multi-directional air outlet and the stirring of the heat conduction oil can improve the uniformity of preheating. Due to the reason of the flow distance of the heat conduction oil, the preheating temperature increases from low to high, and the insulator is gradually heated to the corresponding temperature. Gradual heating can avoid thermal stress caused by rapid temperature changes and prevent the insulator blank from cracking due to excessive temperature difference between the inside and outside due to too fast heating. Subsequently, the flue gas will enter the spray module 300 and be discharged after being treated.

The bottom ends of the two bevel gear columns 257 are respectively fixedly connected to second fan blades 258. One end of each of the two long rods 251 extends outside the preheating box 130. Second driving rollers 2510 are fixedly connected to the outer surfaces of the two long rods 251. A second driving belt 2511 is drivingly connected between the outer surfaces of the two second driving rollers 2510. The stirring component 270 includes two stirring rods 271 rotatably connected inside the heat conduction oil tank 210. One end of each of the two stirring rods 271 extends outside the heat conduction oil tank 210. A plurality of stirring blades 272 are fixedly connected to the outer surfaces of the two stirring rods 271. Linkage gears 273 are fixedly connected to the outer surfaces of the two stirring rods 271. The outer surfaces of the two linkage gears 273 are engaged with each other, and both of the two linkage gears 273 are located outside the heat conduction oil tank 210. The driving component 260 includes a first motor 261 fixedly connected to one side of the preheating box 130.

[0024] The first motor 261 is turned on, and the first motor 261 will drive one of the stirring rods 271 through the linkage of the chain 263 and the sprocket 262. The two stirring rods 271 are rotated synchronously through the meshing of the two linkage gears 273. The multiple stirring blades 272 stir the heat transfer oil, so that the heat transfer oil is heated more evenly. The circulation pump 243 is turned on, so that the heat transfer oil inside the heat transfer oil tank 210 enters the n-shaped heat transfer pipe 241 for heat conduction. The heat transfer oil subsequently returns to the inside of the heat transfer oil tank 210 through the return pipe 244, allowing the heat transfer oil to circulate. At the same time, the first motor 261 will drive one of the long rods 251 to rotate. The two long rods 251 are rotated through the linkage of the second transmission belt 2511, so that the two first large bevel teeth 259 rotate and transmit the two bevel gear columns 257 to drive the second blade 258 to rotate. The first transmission belt 255 drives the rotating shaft 252 to drive the first blade 253 to rotate, so that the first blade 253 and the second blade 258 can supply air on both sides and the top, and the wind is heated by the n-shaped heat pipe 241 and the heat conducting strip 242 and blown to the insulator, so that the insulator can achieve a preheating effect when passing through the inside of the n-shaped heat conducting pipe 241. The multi-directional air outlet and the stirring of the heat conducting oil can improve the uniformity of preheating.

[0026] When the cooling oil returns to the heat transfer oil tank 210, it will be filtered through the filter net bag 290 to prevent the impurities in the cooling oil from affecting the preheating effect due to long-term use. The impurities in the filter net bag 290 can be poured out by flipping open the steering plate 280, making it easier for the staff to handle.

[0027] The spray module 300 includes a spray tower 310 fixedly connected to the top of the heat-conducting oil tank 210. A filter 360 is installed at the top of the spray tower 310. A spray assembly 340 is arranged at the upper part of the inner wall of the spray tower 310. The top end of the smoke exhaust pipe 220 extends into the inner wall of the spray tower 310 and is fixedly connected to a smoke inlet pipe 320. Air holes are formed in the lower part of the outer surface of the smoke inlet pipe 320. A drain pipe 330 is fixedly connected to the lower part of the outer surface of the spray tower 310. The spray assembly 340 includes two mounting cross plates 341 both fixedly connected inside the spray tower 310.

Spray water pipes 343 are fixedly connected to the opposite ends of the two inner rotating pipes 342. A plurality of nozzles are fixedly connected to the lower parts of the outer surfaces of the two spray water pipes 343. Two connecting pipes 344 are fixedly connected to the outer surface of the spray tower 310. One ends of the two connecting pipes 344 are respectively rotatably connected to the adjacent ends of the two inner rotating pipes 342. Joints 350 are installed at the other ends of the two connecting pipes 344 and one end of the drain pipe 330. The spray assembly 340 further includes a second motor 346 fixedly connected to the upper part of the outer surface of the spray tower 310. A second large bevel gear 347 is fixedly connected to the output shaft of the second motor 346. Tapered sleeve gears 345 are fixedly connected to the outer surfaces of the two inner rotating pipes 342. Both of the two tapered sleeve gears 345 are meshed with the second motor 346.

[0028] The flue gas will enter the interior of the spray tower 310 and be discharged through the air holes. The connecting pipes 344 are connected to an external water supply pipe through the joints 350. The water supply pipe will supply water to the two circulating pumps 243 through the connecting pipes 344 and the inner rotating pipes 342. The water is sprayed out through a plurality of nozzles. By turning on the second motor 346, the two second motors 346 will be driven by the second large bevel gear 347, causing the two spray water pipes 343 to rotate in opposite directions for spraying, so as to achieve a more comprehensive spraying effect on the flue gas.

[0029] The implementation principle of the embodiment of the present invention is as follows: During use, the flue gas of the furnace body 120 will be discharged through the exhaust pipe 220. The discharged flue gas conducts heat through the heat conduction ring 230, thereby heating the heat conduction oil inside the heat conduction oil tank 210. When the first motor 261 is turned on, the first motor 261 will drive one of the stirring rods 271 through the linkage of the chain 263 and the sprocket 262. Through the meshing of the two linkage gears 273, the two stirring rods 271 rotate synchronously, and the multiple stirring blades 272 stir the heat conduction oil, so that the heat conduction oil is heated more evenly. When the circulation pump 243 is turned on, the heat conduction oil inside the heat conduction oil tank 210 enters the n-shaped heat conduction pipe 241 for heat conduction, and then the heat conduction oil returns to the inside of the heat conduction oil tank 210 through the return pipe 244, enabling the heat conduction oil to circulate. At the same time, the first motor 261 will drive one of the long rods 251 to rotate. Through the linkage of the second transmission belt 2511, the two long rods 251 rotate, causing the two large first bevel gears 259 to rotate and drive the two bevel gear columns 257 to drive the second fan blades 258 to rotate. Through the transmission of the first transmission belt 255, the rotating shaft 252 drives the first fan blade 253 to rotate, so that the first fan blade 253 and the second fan blade 258 supply air from both sides and the top. The air is heated by the n-shaped heat conduction pipe 241 and the heat conduction strip 242 and blown towards the insulator, so that the insulator achieves a preheating effect when passing through the inside of the n-shaped heat conduction pipe 241. The multi-directional air outlet and the stirring of the heat conduction oil can improve the uniformity of preheating. Due to the reason of the flow distance of the heat conduction oil, the preheating temperature rises from low to high, and the insulator is gradually heated to the corresponding temperature. Gradual temperature rise can avoid thermal stress caused by rapid temperature changes and prevent the insulator blank from cracking due to excessive temperature difference between the inside and outside. At the same time, by driving the stirring assembly 270 and the heat conduction assembly 240 with a single first motor 261, the overall cost and energy consumption can be reduced. When the cooling oil returns to the inside of the heat conduction oil tank 210, it will be filtered through the filter net bag 290 to prevent impurities in the cooling oil from affecting the preheating effect during long-term use. By flipping and opening the turning plate 280, the impurities inside the filter net bag 290 can be poured out, facilitating the staff to handle. Subsequently, the flue gas will enter the spray tower 310 and be discharged through the air outlet holes. The connecting pipe 344 is connected to the external water supply pipe through the joint 350. The water supply pipe will supply water to the two circulation pumps 243 through the connecting pipe 344 and the inner rotating pipe 342. The water is sprayed out through multiple nozzles, and by turning on the second motor 346, the second motor 346 will drive the two second motor 346 through the second large bevel gear 347, causing the two spray pipes 343 to rotate in the opposite direction for spraying, so that a more comprehensive spraying effect on the flue gas can be achieved. Subsequently, the flue gas is further processed and discharged through the filter 360.

[0030] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
