Description

Technical Field

[0001] This utility model relates to the field of kiln technology, and in particular to a novel kiln rapid ignition and start-up device. Background Technology

[0002] Kilns play a vital role in industrial production and various material processing fields, and are widely used in many industries such as ceramics, glass, metallurgy, and building materials. They are key equipment for achieving high-temperature processing. In the operation of a kiln, ignition and startup are crucial steps. Traditional kiln ignition methods have many drawbacks. For example, manual ignition not only poses significant safety risks, such as the possibility of deflagration at the moment of ignition, which can cause flames to fly and result in accidental burns to operators, but the ignition process is also greatly affected by human factors, making it difficult to guarantee the stability and consistency of ignition. At the same time, some kilns using fixed igniters are prone to damage due to the igniters being exposed to high-temperature environments for extended periods, resulting in a short service life. Furthermore, installation and disassembly are inconvenient, and maintenance and replacement are time-consuming, affecting production efficiency. In addition, some ignition devices cannot accurately control the fuel and air supply ratio, leading to incomplete combustion, which wastes energy and may cause environmental pollution.

[0003] A Chinese patent with publication number CN222378777U discloses a kiln for burning natural gas cylinders. When ignition is needed, an electric push rod is activated, which drives a movable rod to extend into the kiln wall. This movable rod causes a movable plate to move upward, allowing the igniter to extend out of the insulation box. The movable plate presses against the top of the movable groove, causing the movable rod to continue moving the insulation box upward, bringing it closer to the combustion area of ​​the air and natural gas inlet pipes. Natural gas is then ignited by the igniter. When the igniter is not needed, the electric push rod causes the igniter to retract into the insulation box, moving it away from the combustion area of ​​the air and natural gas, thus improving the igniter's service life.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: After the kiln is in operation, the dust generated inside it will accumulate above the igniter due to gravity settling or airflow disturbance. Especially when the igniter is a top-exposed structure or installed in a low position, the dust can easily cover the electrode tip or nozzle outlet, causing the electrode to be unable to break through the air to generate a spark, the nozzle to be blocked, or the mixed gas ratio to be abnormal, which in turn leads to problems such as ignition failure, increased equipment wear and tear, and decreased production efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that dust inside the kiln will accumulate above the igniter due to gravity settling or airflow disturbance, which will prevent the electrode from breaking through the air to generate a spark. To this end, we propose a new type of kiln rapid ignition and start-up device.

[0006] To achieve the above objectives, this application adopts the following technical solution: a novel kiln rapid ignition and start-up device, including a base, a kiln is provided at the upper end of the base, and an ignition component is provided at the lower end of the kiln. When the device is in use, the ignition component ignites the mixed gas inside the kiln, thereby rapidly increasing the temperature inside the kiln.

[0007] Preferably, the bottom of the kiln is provided with an isolation groove, the inside of which is provided with a circular groove, and a square groove is provided on one side of the circular groove. Both the circular groove and the square groove are matched with the ignition assembly.

[0008] Preferably, the ignition assembly includes an electric telescopic rod, with an igniter fixedly installed at the drive end of the electric telescopic rod. A compression piston plate is fixedly installed on the outside of the igniter, and the ignition end of the igniter matches the first circular groove. When igniting the kiln, the igniter is pushed out of the inside of the first circular groove by activating the electric telescopic rod to ignite the mixed gas inside the kiln.

[0009] Preferably, a heat insulation plate is fixedly installed inside the isolation groove. A second circular groove is opened in the center of the heat insulation plate. The second circular groove and the first circular groove are located on the same vertical plane. A heat insulation cover is rotatably installed inside the second circular groove. When the igniter is not in use, the igniter is stored inside the second circular groove. The heat insulation plate protects the igniter from excessive heat around it, preventing damage to the igniter. At the same time, the heat insulation cover protects the ignition position of the igniter, preventing dust from falling into the ignition position and causing ignition failure.

[0010] Preferably, a connecting rod is fixedly installed on one side of the heat insulation cover, and two sets of torsion springs are installed on the outer sides of both ends of the connecting rod. One end of the torsion spring is fixedly connected to the heat insulation plate, and both ends of the connecting rod are rotatably connected to the heat insulation cover. When the igniter is not in use, the igniter is stored in the second circular groove. When ignition is required, the electric telescopic rod is activated to push the igniter out from the inside of the first circular groove, and the two sets of heat insulation covers are lifted up. After the ignition process inside the kiln is completed, the electric telescopic rod is retracted to retract the igniter. Under the action of the torsion springs, the two sets of heat insulation covers automatically flip and close, closing and protecting the ignition position of the igniter.

[0011] Preferably, the upper end of the heat insulation plate is provided with a squeezing shell, the lower end of the squeezing shell matches the square groove, and multiple sets of one-way blowing valves are installed through the side of the squeezing shell near the second circular groove. A one-way suction valve is provided on the other side of the squeezing shell. The squeezing piston plate is located inside the squeezing shell and is slidably connected to it. When the electric telescopic rod pushes the igniter out of the first circular groove, the squeezing piston plate on the outside of the igniter rises synchronously, gradually squeezing the air inside the squeezing shell, so that the air pressure inside the squeezing shell increases. When the one-way blowing valve reaches the pressure limit, the gas is squeezed out in the form of pulses, blowing away the dust on the upper end of the heat insulation cover, preventing the dust from falling into the ignition position of the igniter when the heat insulation cover is pushed open, causing the kiln to fail to ignite. When the igniter is retracted, the squeezing shell replenishes the gas inside it through the one-way suction valve for use in the next dust cleaning.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by setting an isolation groove, a circular groove, and a square groove at the bottom of the kiln to match the ignition assembly, an electric telescopic rod is used to drive the igniter to extend and ignite the mixed gas inside the kiln, achieving rapid heating. At the same time, a heat insulation plate is used to store and protect the igniter and block high temperatures when not in use. A rotating heat insulation cover prevents dust from falling into the ignition position. The connecting rod and torsion spring structure on the heat insulation cover allow the heat insulation cover to automatically open when the igniter extends and automatically close when it retracts, improving the convenience of protection. The extrusion shell and extrusion piston plate, together with a one-way blowing valve and an intake valve, achieve pulse-type dust removal through air pressure changes during the raising and lowering of the igniter, avoiding dust affecting the reliability of ignition.

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] Reference Figure 1 As shown, this utility model provides a technical solution: a novel kiln rapid ignition and start-up device, including a base 1, a kiln 2 is provided at the upper end of the base 1, and an ignition component 3 is provided at the lower end of the kiln 2. When the device is in use, the ignition component 3 ignites the mixed gas inside the kiln 2, thereby rapidly increasing the temperature inside the kiln 2.

[0027] Reference Figure 1-3 As shown in this embodiment: the bottom of the kiln 2 is provided with an isolation groove 21, the inside of the isolation groove 21 is provided with a circular groove 22, and a square groove 23 is provided on one side of the circular groove 22. Both the circular groove 22 and the square groove 23 are matched with the ignition assembly 3.

[0028] Reference Figure 4-5 As shown in this embodiment: the ignition assembly 3 includes an electric telescopic rod 31, an igniter 32 is fixedly installed on the drive end of the electric telescopic rod 31, a compression piston plate 33 is fixedly installed on the outside of the igniter 32, and the ignition end of the igniter 32 matches the circular groove 22. When igniting the kiln 2, the igniter 32 is pushed out from the inside of the circular groove 22 by activating the electric telescopic rod 31 to ignite the mixed gas inside the kiln 2.

[0029] Reference Figure 4-7 As shown in this embodiment: a heat insulation plate 24 is fixedly installed inside the isolation groove 21. A circular groove 241 is opened in the center of the heat insulation plate 24. The circular groove 241 and the circular groove 22 are located on the same vertical plane. A heat insulation cover 242 is rotatably installed inside the circular groove 241. When the igniter 32 is not in use, the igniter 32 is stored inside the circular groove 241. The heat insulation plate 24 protects the igniter 32 from excessive temperature and damage. At the same time, the heat insulation cover 242 protects the ignition position of the igniter 32 from dust falling into the ignition position and causing the igniter 32 to fail to ignite.

[0030] Reference Figure 6-8 As shown in this embodiment: A connecting rod 2421 is fixedly installed on one side of the heat insulation cover 242. Two sets of torsion springs 2422 are installed on the outer sides of both ends of the connecting rod 2421. One end of the torsion spring 2422 is fixedly connected to the heat insulation plate 24, and both ends of the connecting rod 2421 are rotatably connected to the heat insulation cover 242. When the igniter 32 is not in use, the igniter 32 is stored in the second circular groove 241. When ignition is required, the electric telescopic rod 31 is activated to push the igniter 32 out of the inside of the first circular groove 22, and the two sets of heat insulation covers 242 are lifted up. After the ignition process inside the kiln 2 is carried out, the electric telescopic rod 31 is retracted to retract the igniter 32. Under the action of the torsion spring 2422, the two sets of heat insulation covers 242 automatically flip and close, closing and protecting the ignition position of the igniter 32.

[0031] Reference Figure 4-9 As shown in this embodiment: an extrusion shell 243 is provided at the upper end of the heat insulation plate 24, and the lower end of the extrusion shell 243 matches the square groove 23. Multiple sets of one-way blowing valves 2431 are installed through the side of the extrusion shell 243 near the second circular groove 241, and a one-way suction valve 2432 is provided on the other side of the extrusion shell 243. The extrusion piston plate 33 is located inside the extrusion shell 243 and is slidably connected to it. When the electric telescopic rod 31 pushes the igniter 32 out of the inside of the first circular groove 22, the extrusion piston plate 33 on the outside of the igniter 32 rises synchronously. The air inside the extrusion shell 243 is gradually squeezed, causing the air pressure inside the extrusion shell 243 to increase. When the one-way air valve 2431 reaches the pressure limit, the gas is squeezed out in the form of pulses, blowing away the dust on the top of the heat insulation cover 242. This prevents the dust from falling into the ignition position of the igniter 32 when the heat insulation cover 242 is pushed open, causing the kiln 2 to fail to ignite. When the igniter 32 is retracted, the extrusion shell 243 replenishes the gas inside through the one-way air intake valve 2432 for use in the next dust cleaning.

[0032] Working principle: When the device is working, the electric telescopic rod 31 is activated to drive the igniter 32 out of the circular groove 22, igniting the mixed gas in the kiln 2 and rapidly raising its temperature. After ignition, the electric telescopic rod 31 retracts to retract the igniter 32 back into the circular groove 241. At this time, the heat insulation plate 24 blocks the high temperature, and the heat insulation cover 242 closes under the action of the torsion spring 2422 to protect the ignition end. During the lifting and lowering of the igniter 32, the extrusion piston plate 33 slides in the extrusion shell 243, and pulse cleaning is achieved through the one-way blowing valve 2431 and the one-way suction valve 2432 to prevent dust from affecting ignition.

[0033] The scope of the utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of the utility model, and all such modifications and variations should fall within the protection scope of the utility model.
