Abstract
Description
Technical Field
[0001] The utility model relates to an ignition device for a coke oven riser pipe, belonging to the technical field of coke ovens. Background Art
[0002] The riser pipe is installed at the riser pipe orifice on the top of the coke oven to export the raw gas in the carbonization chamber, which is an accessory equipment of the coke oven. A water seal cover is provided on the upper part of the bridge pipe of the riser pipe to prevent the raw gas from escaping and polluting the atmosphere. When loading coal into the carbonization chamber, steam or ammonia water is used to generate negative pressure to guide the raw gas into the gas collecting pipe to reduce the smoke escaping from the coal charging hole. A flap (also known as a water seal valve) is installed on the flap seat. When discharging coke from the carbonization chamber, the flap is closed, and the ammonia water sprayed from the bridge pipe overflows along the periphery of the flap to form a water seal to prevent the raw gas from escaping from the gas collecting pipe.
[0003] At present, when the existing coke oven riser pipe discharges soot, it is necessary to manually ignite the soot from the inside, which not only poses a danger to the human body but also causes air pollution. Summary of the Utility Model
[0004] In order to solve the technical problems existing in the prior art, the utility model provides an ignition device for a coke oven riser pipe with a simple structure, reasonable design, capable of automatic ignition and more convenient operation.
[0005] To achieve the above object, the technical solution adopted by the utility model is an ignition device for a coke oven riser pipe, which includes an adjustment bracket installed on one side of the riser pipe. An ignition driving device is installed on the adjustment bracket, and an ignition rod is installed on the ignition driving device. The ignition driving device includes an oil cylinder bracket, a hydraulic oil cylinder, a limit rod and a control board. The oil cylinder bracket is installed on the adjustment bracket, the hydraulic oil cylinder is installed on the oil cylinder bracket, a sliding track is also installed on the oil cylinder bracket. A guiding groove for sliding installation on the sliding track is provided on one side of the limit rod. One end of the limit rod and the piston rod of the hydraulic oil cylinder are respectively fixed on the control board, and the ignition rod is installed on the control board.
[0006] Preferably, a limit support is further installed at the other end of the limit rod, and the ignition rod is respectively fixed on the control board and the limit support through a pressing plate.
[0007] Preferably, the length of the ignition rod is 2.5 - 3m.
[0008] Preferably, the adjustment bracket includes a first bracket and a second bracket. A plurality of height adjustment holes are provided on the first bracket, and the second bracket is fixed on the first bracket through bolts.
[0009] Compared with the prior art, the utility model has the following technical effects: The structure of the utility model is simple and reasonably designed. An ignition rod driven by a hydraulic cylinder is installed on one side of the riser pipe. When the water seal cover of the riser pipe is opened, the ignition rod moves forward under the drive of the hydraulic cylinder, and the ignition rod ignites the raw coal gas. After ignition, the ignition rod automatically retracts. The operation is simple and convenient. It can realize automatic ignition and improve the safety and reliability of the operation at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
