Abstract
Description
Technical Field
[0001] This utility model relates to the field of ignition technology for sintering machines, and in particular to an ignition device for sintering machines. Background Technology
[0002] In the sinter production process, the igniter uses the high-temperature flame generated by the combustion of coal gas to ignite the mixture of iron-containing raw materials, fuel, and flux after mixing and granulation, ultimately forming sinter. Currently, the ignition operation is done manually: workers hold a torch and insert it into the igniter through the ignition port to open the gas valve and ignite the gas. However, due to the airflow generated by the main exhaust fan, the torch flame is easily extinguished, often requiring multiple insertions to successfully ignite. If the gas fails to ignite promptly after being ejected, it not only leads to production halts but also poses a safety hazard of gas leakage. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a sintering machine ignition device in response to the above-mentioned technical deficiencies. The device uses a rotatable ignition part between the clamping plates at one end of the ignition rod, and multiple burners are set in the ignition part to achieve ignition. The meshing of the rack and gear drives the ignition part to rotate to the ignition position, which solves the problem that the torch is easily extinguished when a person holds it and puts it into the igniter through the ignition port.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a sintering machine ignition device, including a hollow ignition rod, one end of which is provided with two sets of parallel clamping plates, and an ignition part is rotatably connected between the two sets of clamping plates. The ignition part is provided with multiple burners, and a rotating shaft is provided in the middle of the ignition part. One end of the rotating shaft is provided with a gear, one side of the gear is provided with a rack, one end of the rack is provided with an extension rod, the extension rod passes through the ignition rod, and the end of the extension rod away from the rack is provided with a pull handle, which protrudes out of the outside of the ignition rod.
[0005] To further optimize this technical solution, an ignition needle is provided on one side of the burner, and an air passage is provided inside the rotating shaft. One end of the air passage is connected to multiple burners, and the other end of the air passage is connected to a rotary joint. An air pipe is provided on the side of the ignition rod away from the ignition part, and the air pipe is connected to the rotary joint through an external pipe.
[0006] To further optimize this technical solution, the gas tube is inclined and set on one side of the ignition rod, a handle is provided on the side of the ignition rod away from the gas tube, and an ignition knob is provided on the side of the ignition rod near the handle.
[0007] To further optimize this technical solution, one side of one of the clamping plates is provided with a first limiting bolt and a second limiting bolt. When the ignition part is rotated to be perpendicular to the length direction of the clamping plate, the ignition part contacts the first limiting bolt. When the ignition part is fully screwed into the space between the two clamping plates, the ignition part contacts the second limiting bolt.
[0008] To further optimize this technical solution, a limiting groove is provided on the side of the rack away from the gear, and the rack is slidably positioned in the limiting groove, which is fixed to one side of one of the clamping plates.
[0009] Compared with the prior art, this utility model has the following advantages: 1. It adopts a rotatable ignition part between the clamping plates at one end of the ignition rod, and sets multiple burners in the ignition part to achieve ignition. The ignition part is driven to rotate by meshing rack and gear, which is simple in structure, has a low failure rate, and high operating efficiency; 2. It ignites multiple burners by igniting multiple ignitions, avoiding the problem of easy extinguishing of a single ignition flame; 3. The rotation of the ignition part is limited by the first limit bolt and the second limit bolt, ensuring the accuracy of the ignition part position. Attached Figure Description

[0017] Combination Figures 1 to 3 As shown, a sintering machine ignition device includes a hollow ignition rod 1. One end of the ignition rod 1 has two sets of parallel clamping plates 11. A rectangular ignition section 2 is rotatably connected between the two sets of clamping plates 11. The ignition section 2 has multiple burners 23, specifically eight burners 23, respectively positioned on opposite sides of the ignition section 2 corresponding to the clamping plates 11. Each burner 23 has an ignition needle 24 on one side. The multiple ignition needles 24 are connected to a pulse igniter. A rotating shaft 21 is located in the middle of the ignition section 2. One end of the rotating shaft 21 has a coaxially arranged gear 22. The gear 22 is located within the ignition section. Between the gear 22 and one of the clamping plates 11, a rack 3 meshes with one side of the gear 22. A limiting groove 110 is provided on the side of the rack 3 away from the gear 22. The rack 3 is slidably disposed in the limiting groove 110. The limiting groove 110 is fixed to one side of one of the adjacent clamping plates 11. An extension rod 31 is provided at one end of the rack 3. The extension rod 31 passes through the ignition rod 1. A handle 32 is provided at the end of the extension rod 31 away from the rack 3. The handle 32 protrudes out of the outside of the ignition rod 1. A sealing part 13 is provided at the end of the ignition rod 1 corresponding to the handle 32. The sealing part 13 is provided to prevent the gas in the igniter from overflowing.
[0018] Combination Figures 2 to 4 As shown, a gas passage 210 is provided at one end of the rotating shaft 21. One end of the gas passage 210 is connected to multiple burners 23 via a connecting pipe, and the other end of the gas passage 210 is connected to a rotary joint 4. A gas pipe 5 is provided on the side of the ignition rod 1 away from the ignition part 2. The gas pipe 5 is connected to the rotary joint 4 via an external pipe 41. The gas pipe 5 is inclinedly arranged on one side of the ignition rod 1 and is connected to the gas storage tank. A handle 10 is provided on the side of the ignition rod 1 away from the gas pipe 5. An ignition knob 12 is provided on the side of the ignition rod 1 near the handle 10. The ignition knob 12 is connected to the control circuit of the pulse igniter via a wire. At the same time, a gas valve is also coaxially connected to the ignition knob 12. The opening and closing of the gas valve is used to control the opening and closing of the gas pipe 5.
[0019] Combination Figure 2As shown, one side of one of the clamping plates 11 is provided with a first limiting bolt 6 and a second limiting bolt 7. When the ignition part 2 is rotated to be perpendicular to the length direction of the clamping plate 11, the ignition part 2 contacts the first limiting bolt 6 to achieve limiting. When the ignition part 2 is fully screwed into the space between the two clamping plates 11, the ignition part 2 contacts the second limiting bolt 7 to achieve limiting.
[0020] When in use, the ignition part 2 is stored between the two sets of clamping plates 11 and parallel to the length direction of the clamping plates 11 when the ignition device is not in operation. This can protect the nozzle 23 and the ignition needle 24, and on the other hand, it can easily extend the ignition rod 1 into the igniter. When the igniter of the sintering machine needs to be ignited, first insert the ignition device in its initial state into the igniter, then pull the handle 32, which in turn pulls the rack 3 to slide in the limiting groove 110 via the extension rod 31, thereby driving the meshing gear 22 to rotate. The rotation of the gear 22 drives the rotating shaft 21 and the ignition part 2 to rotate until the ignition part 2 contacts the first limiting bolt 6. At this time, the position of the ignition part 2 is perpendicular to the clamping plate 11, and the burner nozzle 23 is fully exposed. Then, press and rotate the ignition knob 12 to connect the gas tank and the burner nozzle 23. The gas flow here is controlled by the gas valve, and the principle is similar to the control knob of a household gas stove, which will not be described in detail here. The ignition needle 24 is then activated to discharge and ignite the burner nozzle 23, thereby igniting the igniter.
[0021] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
