[0003] When existing burner nozzles are installed in the boiler combustion chamber for combustion assistance, the fuel burning materials in the boiler combustion chamber may produce slag particles. The slag may adhere to the surface of the nozzle, which may cause nozzle blockage and thus affect the stability of nozzle use. Utility Model Content

[0004] This invention provides an anti-clogging burner nozzle, which aims to solve the problem that when existing burner nozzles are installed in the boiler combustion chamber for combustion assistance, the fuel burning materials in the boiler combustion chamber may produce slag particles, which may adhere to the surface of the nozzle and cause clogging, thereby affecting the stability of nozzle use.

The flow divider shroud is threadedly connected to the end of the sleeve. One end of the sleeve has a slot 1, and the inner side wall of slot 1 has a slot 2. The limiting clamp is threadedly connected to the side wall of slot 1 near slot 2. The flow divider assembly includes a component movably connected to a separation seat. The side wall of the separation seat has several holes 1. A slider is fixed at the end of the separation seat. A limiting tube is inserted into the middle of the other end of the slider. A spring is wound around the outer surface of the limiting tube. A plug is inserted into the middle of the other end of the sleeve.

[0006] Preferably, the outer surface of the sleeve is provided with a threaded groove for threaded connection of the diverter shroud, and a number of slots are provided on the side wall of the diverter shroud. A number of slots are provided on the inner side wall of the diverter shroud. Slots 2 and 3 are connected to slot 1 in sequence, which further improves the safety of the separation seat protection.

[0007] Preferably, two mounting ears are symmetrically fixed on the side wall of the sleeve, and each mounting ear has a threaded groove on its surface, which improves the convenience of sleeve installation and positioning.

[0008] Preferably, a second plug is inserted into the side wall of the sleeve near the first plug, and the second plug is connected to the first slot, which improves the convenience of air circulation.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] Please see Figure 1-4The present invention provides an embodiment of an anti-clogging burner nozzle, comprising a workbench sleeve 1, a flow divider assembly 2, a limiting clamp 3, and a flow divider shroud 4. The flow divider shroud 4 is threadedly connected to the end of the sleeve 1. One end of the sleeve 1 has a slot 11, and the inner side wall of the slot 11 has a slot 2 12. The limiting clamp 3 is threadedly connected to the side wall of the slot 11 near the slot 2 12. The flow divider assembly 2 includes a component movably connected to a separator 201. The limiting clamp 3 has a groove 13 in the middle for the separator 201 to slide and support the limiting. The external dimensions of the separator 201 and the internal dimensions of the groove 13 are related. The size matching improves the stability of the separation seat 201 movement. Several slots 202 are provided on the side wall of the separation seat 201 for fuel separation. A slider 203 is fixed to one end of the separation seat 201. A limiting tube 204 is inserted into the middle of the other end of the slider 203. The limiting tube 204 is connected to the slots 202 in sequence. A spring 205 is wound around the outer surface of the limiting tube 204. A plug 7 is inserted into the middle of the other end of the sleeve 1 for connecting to a pipeline to transport fuel. The plug 7 is connected to the inside of slots 12 and 11 in sequence. The external dimensions of slot 12 are consistent with the internal dimensions of the slider 203. The dimensions are compatible, and the two ends of the spring 205 are fixed sequentially to the bottom end of the slider 203 and the inner side wall of the slot 12, which improves the stability of the separation seat 201 reset. The outer surface of the sleeve 1 is provided with a threaded groove 5 for the flow divider 4 to be threaded. Several slots 9 are provided on the side wall of the flow divider 4, and several slots 10 are provided on the inner side wall of the flow divider 4. The slots 9 and 10 are connected to the slot 11 in sequence, which further improves the safety of the separation seat 201. The plug 7 is connected to the fuel tank through a pipe to supply oil. High-pressure oil enters the plug 7 and the slot 11 in sequence. Inside the nozzle 2, the fuel enters the separator 201 through the limiting tube 204 and is sprayed out through several holes and slots 202. It is then atomized and sprayed out through several holes and slots 9 and 10, which facilitates the complete combustion of fuel oil to assist in igniting boiler fuel. When slag dust is generated in the boiler combustion chamber, the diverter hood 4 is fitted on the end of the sleeve 1 to achieve initial protection. When the fuel oil supply stops, the elastic force of the spring 205 acts on the side wall of the slider 203, which facilitates the retraction of the sleeve 1 into the inside of the slot 12, thereby preventing dust from blocking the holes and slots 202 and improving the stability of the nozzle.

[0021] Two mounting ears 6 are symmetrically fixed on the side wall of the sleeve 1. The surface of the mounting ears 6 is provided with threaded grooves 14, which improves the convenience of the sleeve 1 installation and positioning. A plug 8 is inserted into the side wall of the sleeve 1 near the plug 7. The plug 8 is connected to the groove 11, which improves the convenience of air circulation.

[0022] Working Principle: When using this type of anti-clogging burner nozzle, the operator first inserts the sleeve 1 into the side wall of the boiler combustion chamber. The boiler combustion chamber is the part of the boiler used to burn fuel to generate heat energy. Its main function is to mix fuel with air and achieve combustion under appropriate conditions. The boiler combustion chamber is existing technology. The plug 7 is connected to the fuel tank through a pipeline for fuel supply. High-pressure oil enters the interior of the plug 7 and the slot 12 in sequence, and then enters the separator 201 through the limit tube 204. It is then sprayed out through several holes and slots 202, and then atomized through several holes and slots 9 and 10 before being sprayed out. This facilitates the complete combustion of fuel oil to assist in igniting the boiler fuel. When slag dust is generated in the boiler combustion chamber, the diversion hood 4 is fitted onto the end of the sleeve 1 to achieve initial protection. When the fuel oil supply stops, the elastic force of the spring 205 acts on the side wall of the slider 203, which facilitates the retraction of the sleeve 1 into the interior of the slot 12, thereby preventing dust from clogging the holes and slots 202 and improving the stability of the nozzle.

[0023] Secondly, plug 28 is connected to slot 11, and plug 28 is connected to the blower outlet through a pipe, so that air can enter slot 11 through slot 29 and then be sprayed out from several slots 29 and slot 30. This facilitates the increase of oxygen for combustion and simultaneously purifies slots 29 and slot 310, thereby preventing them from becoming clogged and further improving the safety of the nozzle.
