Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Reference Figures 1-4 This is an embodiment of the present invention, which provides an anti-clogging boiler burner nozzle, comprising: The support mechanism 100 includes a furnace wall 110, an output pipe 120 that communicates with the output end of the burner and extends into the interior of the boiler, a movable pipe body 130 that is movably installed inside the output pipe 120, and a nozzle 140 that is fixed to the end of the movable pipe body 130. The anti-clogging mechanism 200 includes a telescopic protection component 210 for extending and retracting the nozzle 140, and a dustproof component 220 used in conjunction with the telescopic protection component 210 to prevent dust from being opened and closed at the end of the output pipe 120.

[0019] The telescopic protection component 210 works in conjunction with the dustproof component 220 to achieve a dual anti-clogging function of telescopic protection for the nozzle 140 and dustproof protection for the end of the output pipe 120, effectively reducing the entry of impurities into the nozzle 140 and the output pipe 120, and ensuring the normal operation of the nozzle.

[0020] Specifically, the telescopic protection component 210 includes a mounting bracket 211 fixed to one side of the furnace wall 110, a drive wheel 212 rotatably mounted on the inner side of the mounting bracket 211 via a connecting rod, a groove 213 formed on the surface of the moving tube 130 and used in conjunction with the drive wheel 212, and a motor 214 fixed to one side of the furnace wall 110 for driving the drive wheel 212 to rotate. The groove 213 extends along its axis.

[0021] Among them, the motor 214 drives the drive wheel 212 to rotate, and the drive wheel 212 meshes with the concave tooth groove 213 on the surface of the moving tube 130 to drive the extension and retraction of the nozzle 140, so as to realize the extension of the nozzle 140 when working and the retraction protection when idle, thereby reducing the risk of blockage.

[0022] Furthermore, the bottom of the output tube 120 is provided with a connecting groove that cooperates with the rotation of the drive wheel 212, and the drive wheel 212 is engaged with the inside of the concave tooth groove 213 through the connecting groove.

[0023] Preferably, a worm gear 215 is fixedly installed at the output end of the motor 214, and a worm wheel 216 is fixedly installed on the drive wheel 212 through a connecting rod, with the worm gear 215 meshing with the worm wheel 216.

[0024] Among them, the worm 215 at the output end of the motor 214 meshes with the worm wheel 216 on the connecting rod of the drive wheel 212. By utilizing the speed reduction and torque increase characteristics of the worm gear transmission, not only can the output speed of the motor 214 be reduced to accurately control the extension and retraction speed of the nozzle 140, but the transmission torque can also be increased to ensure that the moving tube 130 has sufficient power to drive the nozzle 140 to extend and retract, so as to adapt to different working conditions.

[0025] Furthermore, the dustproof component 220 includes two dustproof covers 221 for opening and closing the end of the output tube 120, a side plate 222 fixed to the surface of the dustproof cover 221, and a return spring 223 fixed between the side plate 222 and the surface of the output tube 120 and holding the two dustproof covers 221 in a pulling motion.

[0026] The dust cover 221 has a semi-circular structure and its inner side is arc-shaped, so that the nozzle 140 can squeeze the dust cover 221 outward and unfold at the same time.

[0027] Among them, the two dust covers 221 can open and close to prevent dust from the end of the output tube 120. The return spring 223 applies a pulling force to the dust cover 221 through the side plate 222 to ensure that the dust cover 221 is stably closed when idle. The inner arc surface design of the dust cover 221 allows the dust cover 221 to be smoothly squeezed to unfold outward when the nozzle 140 is extended, which does not affect the operation of the nozzle 140 and can be quickly closed to prevent dust after the nozzle 140 retracts.

[0028] Specifically, the top and bottom of the dust cover 221 are respectively fixedly installed with a protruding plate 224, a fixing block 225 fixed to the top and bottom of the output tube 120 respectively, and a positioning rod 226 fixed to the end of the fixing block 225 and used in conjunction with the protruding plate 224 to limit the position of the dust cover 221.

[0029] The surface of the protruding plate 224 is provided with a positioning hole, and the end of the positioning rod 226 passes through the positioning hole.

[0030] The positioning rod 226 passes through the positioning hole on the protrusion 224, which guides and limits the opening and closing movement of the dust cover 221, preventing the dust cover 221 from shifting when opening and closing, ensuring that it always accurately corresponds to the end of the output tube 120, and improving the reliability of dust protection.

[0031] Furthermore, a sealing strip 227 is fixedly installed on one side of the two dust covers 221 that are close to each other, and a sealing groove 228 is opened on the other side to cooperate with the sealing strip 227 to enhance the sealing performance of the two dust covers 221.

[0032] Among them, the sealing protrusion 227 cooperates with the sealing groove 228. When the dust cover 221 is closed, the sealing protrusion 227 is embedded in the sealing groove 228, which greatly improves the sealing performance between the two dust covers 221, effectively preventing small impurities from entering the output pipe 120 from the gap of the dust cover 221, and further enhancing the anti-clogging effect.

[0033] When in use, the motor 214 is started, which drives the worm gear 215 to rotate. The worm gear 215 drives the worm wheel 216 and the drive wheel 212 to rotate. The drive wheel 212 meshes with the groove 213 of the moving tube 130, causing the moving tube 130 and the nozzle 140 to extend outwards from the output tube 120. During the extension of the nozzle 140, the inner arc surface of the dust cover 221 is squeezed, causing the two dust covers 221 to overcome the tension of the return spring 223 and unfold outwards until the nozzle 140 reaches the working position, and the burner begins to output fuel combustion through the nozzle 140.

[0034] After combustion, the control motor 214 reverses, and the drive wheel 212 rotates in the opposite direction, driving the moving tube 130 and nozzle 140 to retract into the output tube 120. As the nozzle 140 retracts, the reset spring 223 pulls the dust cover 221 to reset and close through the side plate 222, and the sealing protrusion 227 is embedded in the sealing groove 228 to achieve dust prevention at the end of the output tube 120, thus completing one working cycle.

[0035] In summary, the telescopic protection component 210 and the dustproof component 220 work together to achieve a dual anti-clogging function of telescopic protection for the nozzle 140 and dustproof protection for the end of the output pipe 120, effectively reducing the entry of impurities into the nozzle 140 and the output pipe 120, and ensuring the normal operation of the nozzle.
