Description
Technical Field
[0001] The utility model relates to the technical field of flame detection devices for electric boilers, in particular to a detection window dredging device for a flame detector. Background Art
[0002] At present, the combustion status of boiler burners in thermal power plants is mainly realized through special flame detectors. Affected by the market situation, thermal power plants mostly purchase economical coal. During the combustion process, the flame detection window is prone to coking and ash accumulation, which affects the detection effect. The detection window needs to be unblocked and cleaned frequently. In addition, the flame detection window is narrow and hot, which is not easy to unblock. At present, ordinary iron rods and hand hammers are mainly used as tools for unblocking, which mainly have the following disadvantages and shortcomings.
[0003] 1-Use an iron rod for dredging and cleaning. The tool is heavy and inconvenient to carry. In addition, during the work process, the iron rod is affected by the heat conduction in the furnace, and the temperature of the handheld part at the end continues to rise, exceeding the human body's tolerance range, and cannot be used continuously. If you accidentally touch the high-temperature part, there is a risk of burns, which endangers personal safety and reduces work efficiency.
[0004] 2-Use ordinary iron rods for dredging and cleaning. There is no gripping part, and it is impossible to exert force. It needs to be dredged with a hammer. There is a risk of accidental injury from hammering. In addition, the working environment is an open work surface, and there is a risk of falling objects from high altitude, which increases the unsafe working factors.
[0005] 3-Use ordinary iron rods for dredging and cleaning. When the furnace pressure fluctuates and presents positive pressure, the detection window will instantly spray high-temperature flue gas, carrying high-temperature dust, directly into the face of the staff, posing a serious risk of burns.

[0022] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the utility model rather than to limit the scope of the utility model. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.
[0023] In a specific embodiment, a flame detector detection window clearing device is provided, including a clearing tube 1, wherein a spike end 1.1 is provided at the front end of the clearing tube 1 for piercing coke and dust accumulation at the detection window, and the sharp end 1.1 effectively improves the cleaning efficiency of the detection window, and the clearing tube 1 has the advantage of being light in weight compared to a solid rod, which is conducive to continuous holding, wherein, in order to maintain the sharpness of the spike end 1.1, the clearing tube 1 is made of medium carbon steel, and the spike end 1.1 is quenched to improve its strength and hardness.
[0024] In this example, in order to avoid the influence of heat conduction and to facilitate the operation with both hands, a wristband 7 is provided at the rear end of the dredging tube 1, and a handle 3 is installed on the outer wall of the dredging tube 1. When in use, one hand can hold the handle 3, and the other hand can grasp the wristband 7. Therefore, it can be very beneficial to the puncture operation of the dredging tube 1, and the heat conduction to the handheld part can be effectively reduced through the handle and the wristband, so as to realize the continuous operation of dredging and cleaning the detection window and improve work efficiency. In order to further avoid the overheating of the handle 3 and the unfavorable grip, an insulation sleeve 4 is sleeved on the outside, which can be a wooden insulation sleeve or a glass fiber insulation sleeve. In this light, a corresponding insulation sleeve can also be sleeved on the wristband 7.
[0025] On this basis, in order to make the handle 3 and the bracelet 7 suitable for different operators, a plurality of threaded heads are arranged along the axial direction on the outer wall of the dredging pipe 1. The handle 3 can be screwed on any one of the threaded heads, and then the relative position of the handle 3 to the bracelet 7 can be adjusted. The adjustment can be more conducive to the operator's force application.
[0026] In this example, in order to avoid the risk of burns and scalds caused by the instantaneous spraying of high-temperature flue gas and high-temperature dust from the detection window directly hitting the face of the staff when the furnace pressure fluctuates and presents a positive pressure, a wind shield 2 is installed on the dredging pipe 1, which can separate the front and rear ends of the dredging pipe 1. When in use, the operator can be placed at the rear end of the wind shield 2, and the wind shield 2 can effectively block the high-temperature dust and flue gas, thereby improving the safety of operation. In this application, the installation form of the wind shield 2 and the dredging pipe 1 preferably has the following two structures:
[0027] The first one is that a mounting hole is provided in the middle of the wind shield 2, and the wind shield 2 is sleeved on the outside of the dredging pipe 1 through the mounting hole, and the specific mounting position of the wind shield 2 can be adjusted according to the use requirements. In order to achieve the fixation of the wind shield 2, an external thread is also provided on the outer wall of the dredging pipe 1. After the wind shield 2 is positioned, the wind shield 2 is fixed on the dredging pipe 1 by two nuts 9 facing each other.
[0028] The second type is also provided with a mounting hole in the middle of the wind shield 2, and is sleeved on the outside of the dredging pipe 1 through the mounting hole. A locking head 2.1 is provided on the periphery of the mounting hole, and a tapered thread is provided on the outside of the locking head 2.1, wherein the locking head 2.1 is petal-shaped, and when the nut 9 is screwed on the locking head 2.1, the petal-shaped locking head 2.1 can be retracted inward, so that the locking head 2.1 is fastened to the outside of the dredging pipe 1, thereby achieving the fixation of the wind shield 2, and facilitating the loading and unloading and position adjustment of the wind shield 2.
[0029] In this example, in order to reduce the backward conduction of heat in the dredging pipe 1, a joint 5 is provided on the outer wall of the dredging pipe 1, and the joint 5 is connected to the inner cavity of the dredging pipe 1. When in use, it is connected to the compressed air pipe 6 through the joint 5, so that compressed air can be supplied to the inner cavity of the dredging pipe 1 and discharged through the spiked end 1.1, so as to take away part of the heat on the dredging pipe 1, and the coke and dust accumulated that can be punctured by the compressed air can be blown forward, so as to prevent the coke and dust from approaching the operating end.
[0030] When in use, in order to prevent compressed air from flowing out of the dredging pipe 1 and facilitate the cleaning of accumulated debris in the dredging pipe 1, a plug 8 is screwed on the rear end of the dredging pipe 1. The plug 8 can be removed during cleaning to improve ease of use.
