[0002] A low - nitrogen burner is a device that adds a blower, an induced draft fan, a frequency converter, uses control valves, and integrates multiple circuits to the traditional burner, enabling clean energy and the burner to operate to provide more efficient heat energy for the boiler, and reducing the nitrogen generated after combustion, making it more environmentally friendly.

[0003] When a traditional low - nitrogen burner is in use, during combustion, it is necessary to mix fuel gas with air. At this time, air needs to be added to the device. Traditional devices often directly draw air into the device without filtering the air. Once the drawn air contains a certain amount of impurities, when the impurities enter the device, they will affect the device and even cause damage to the device. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1 - Figure 5 , a low-nitrogen burner for coke oven gas, including an equipment body 1, a combustion pipe 2 is fixedly assembled on the outer wall of the equipment body 1, a fan 3 is fixedly assembled on the outer wall of the equipment body 1, an air inlet pipe 4 is fixedly assembled on the outer wall of the equipment body 1, a filter bin 5 is installed on the outer wall of the air inlet pipe 4, a filter box 6 is installed in the inner cavity of the filter bin 5, a U-shaped plate 7 is rotatably connected to the outer wall of the filter bin 5, a pull rod 8 is movably sleeved in the inner cavity of the U-shaped plate 7, a limiting plate 10 is fixedly assembled on the outer wall of the pull rod 8, a driving spring 9 is movably sleeved on the outer wall of the pull rod 8, a rotating shaft 11 is rotatably connected to the inner cavity of the air inlet pipe 4, a fan blade 12 is fixedly assembled on the outer wall of the rotating shaft 11, a trigger plate 13 is fixedly assembled on the outer wall of the air inlet pipe 4, and a frequency detector 14 is installed on the top of the trigger plate 13.

[0022] By installing the fan 3 on the outer wall of the equipment body 1, when the equipment body 1 is in use, under the action of the fan 3, external air can be drawn into the inner cavity of the equipment body 1, so that the air is mixed with the fuel gas, so that the fuel gas can be fully mixed to achieve the maximum combustion efficiency and reduce the generation of nitrogen.

[0023] In a preferred implementation mode: both ends of the outer wall of the driving spring 9 are in contact with the outer walls of the U-shaped plate 7 and the limiting plate 10, and the driving spring 9 is made of high-carbon steel.

[0024] By arranging the driving spring 9 on the outer wall of the pull rod 8, under the action of the driving spring 9, the pull rod 8 and the limiting plate 10 can be pushed to fit on the outer wall of the filter bin 5, so as to fix the filter box 6, so that the filter box 6 can only be fixed in the inner cavity of the filter bin 5 and cannot shift from the inner cavity of the filter bin 5.

[0025] In a preferred implementation mode: the outer wall of the pull rod 8 passes through the outer wall of the U-shaped plate 7 and is connected to the limiting plate 10, and a rubber anti-slip pad is installed on the outer wall of the limiting plate 10 close to the filter bin 5.

[0026] By means of a pull rod 8 arranged in the inner cavity of the U-shaped plate 7 and a driving spring 9 arranged on the outer wall of the pull rod 8, under the action of the driving spring 9, the limiting plate 10 can be attached to the outer walls of the filter chamber 5 and the filter box 6, thereby realizing the fixation of the filter chamber 5 and the filter box 6 and ensuring that the filter box 6 can stably exist in the inner cavity of the filter chamber 5.

[0027] In a preferred embodiment: a plurality of filter holes are formed in the outer wall of the filter box 6, and the positions of the filter holes correspond to the inner cavity of the air inlet pipe 4.

[0028] By means of the filter box 6 arranged in the inner cavity of the filter chamber 5, when air passes through the outer wall of the filter chamber 5, larger impurities contained in the air can be filtered under the action of the outer wall of the filter chamber 5. Subsequently, the air will enter the inner cavity of the filter chamber 5. At this time, smaller impurities contained in the air can be filtered again under the action of the filter box 6 to prevent them from entering the inner cavities of the air inlet pipe 4 and the equipment body 1.

[0029] In a preferred embodiment: a trigger rod is installed on the outer wall of the rotating shaft 11, and the top of the trigger rod can contact the outer wall of the trigger plate 13.

[0030] By means of the trigger rod arranged on the outer wall of the rotating shaft 11, when air flows in the inner cavity of the air inlet pipe 4, the rotating shaft 11 and the fan blade 12 will rotate under the action of the air. During the rotation of the rotating shaft 11, every time it rotates one circle, the trigger rod on the outer wall of the rotating shaft 11 will contact the outer wall of the trigger plate 13 once, thereby generating an electrical signal, which is recorded under the action of the frequency detector 14.

[0031] In a preferred embodiment: a controller and an indicator light are installed on the outer wall of the air inlet pipe 4, and the controller is electrically connected to the frequency detector 14 and the indicator light respectively.

[0032] By means of the installed controller and indicator light, the frequency of the trigger plate 13 being triggered is detected under the action of the frequency detector 14, so as to obtain the number of rotations of the rotating shaft 11 within a certain period of time, thereby reflecting the rotation speed of the rotating shaft 11. When the rotation speed of the rotating shaft 11 decreases, it can be indicated that the air intake volume in the inner cavity of the air inlet pipe 4 decreases. At this time, it is necessary to clean the outer wall of the filter chamber 5 and the outer wall of the filter box 6.

[0033] Working principle: During the use of the above-mentioned equipment, when the combustion operation is carried out normally, under the action of the fan 3 on the outer wall of the equipment body 1, the external air is drawn into the inner cavity of the equipment body 1, so that the fuel gas is mixed with the air, and then ignited, thereby reducing the nitrogen content generated by combustion. During the intake process of the equipment body 1, under the action of the filter chamber 5 and the filter box 6, the sundries existing in the air can be filtered. As the equipment is used, more and more sundries will accumulate in the outer wall of the filter chamber 5 and the inner cavity of the filter box 6, which will affect the normal intake of the equipment. During the normal intake process, the rotation speed of the rotating shaft 11 is constant, so the number of times the trigger plate 13 is triggered obtained by the frequency detector 14 is also constant. Once the outer walls of the filter chamber 5 and the filter box 6 are blocked, the rotation speed of the rotating shaft 11 will decrease, and the number of triggers within a certain period of time will also decrease. At this time, it will be detected under the action of the frequency detector 14, and then the signal will be transmitted to the controller to light up the indicator light to remind the staff to clean the filter chamber 5 and the filter box 6. At this time, only need to pull the pull rod 8, so that the driving spring 9 is compressed, and then the outer wall of the limiting plate 10 is separated from the outer wall of the filter chamber 5, and rotate the pull rod 8, so that the pull rod 8 rotates in the direction away from the filter chamber 5, then the pull rod 8 can be moved from the top of the filter chamber 5 to the side, and at this time the filter box 6 can be taken out to clean the filter box 6, so that the equipment can intake air better.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
