[0026] Embodiment 1 An embodiment of the present application discloses an anti-blocking burner, including: a main body 1, a discharge part 2, a swirl disk 3, a protective net 4, and an observation lens 5; specifically, the main body 1 is a cylindrical tube, including a tube wall and a cylindrical combustion chamber defined by the tube wall; a discharge part 2 is formed at any end of the combustion chamber along the first direction; the first direction is the axial direction of the main body 1; wherein, the discharge part 2 is located at the position where the tube wall penetrates to the external space perpendicular to the first direction; more specifically, an air inlet is formed at a position away from the discharge part 2 along the first direction, and preferably two air inlets are adopted, and the two air inlets are arranged in a line along the first direction; Specifically, the swirl disk 3 is arranged on one side of the discharge part 2 close to the air inlet along the first direction, and the protective net 4 is arranged on one side of the discharge part 2 away from the swirl disk 3 along the first direction; with such an arrangement, the fuel gas and combustion-supporting air enter from the air inlet of the fuel gas, diffuse and mix evenly in the combustion chamber, are ejected from the front end of the burner, encounter the pilot flame in the furnace and burn, forming a strong and powerful flame to bake the materials in front; during the feeding process, the protective net 4 can prevent large-sized materials from entering the inside of the burner, and the fine particles are blocked outside the cyclone disk. After being premixed, the gas can blow away the fine particles at the front end after increasing the speed through the cyclone disk and is discharged from the discharge part 2 at the lower part of the combustion chamber; the risk of blockage can be effectively reduced; more specifically, an observation lens 5 is detachably arranged at one end of the combustion chamber away from the discharge part 2 to observe the combustion condition inside the combustion chamber; through the setting of the above scheme, during operation, workers can view the combustion state of the burner through the observation lens 5, and it is easy to observe whether there is material accumulation inside the burner. If material accumulation occurs, the observation lens 5 can be removed, and then the combustion chamber can be blown with high-pressure gas to clear the blockage.

[0028] In another feasible embodiment, a data collector is installed on the mounting ring 6, and the data collector is a vision collector; for example, an industrial camera or a video camera; it is used to intermittently photograph the internal space of the combustion chamber; the data collector is electrically connected to the central processor, and the central processor receives and processes the electrical signals transmitted by the data collector; the central processor includes a data analysis module to analyze the image information transmitted by the vision collector; the data analysis module can judge the combustion condition of the combustion chamber according to the image information; then an alarm is given through the alarm device electrically connected to the central processor; at this time, the worker makes a blockage removal treatment according to the alarm information sent by the alarm device; through the above solution, it is avoided that the worker needs to often observe through the observation lens 5.

[0029] Embodiment 2 There is a distance X between the swirl disk 3 and the protective net 4 in the first direction, and an adjusting mechanism for adjusting the distance X is arranged on the main body 1; the adjusting mechanism includes: a slider 9, an electromagnet 10, a magnet 11, and an infrared rangefinder 12; wherein, a moving groove is formed in the tube wall in the first direction, and the slider 9 is movably arranged in the moving groove, and the protective net 4 is connected to the slider 9; an electromagnet 10 is arranged in the moving groove, and a magnet 11 corresponding to the electromagnet 10 is arranged on the slider 9; specifically, there is a heat insulation layer between the moving groove and the combustion chamber to reduce the temperature in the moving groove and prevent the electromagnet 10 from being burned out; the electromagnet 10 is electrically connected to the central processor to control the magnetism of the electromagnet 10; the infrared rangefinder 12 is arranged on the slider 9 to detect the distance X; the infrared rangefinder 12 is electrically connected to the central processor; the data analysis module analyzes the electrical signals transmitted by the infrared rangefinder 12. Specifically, air blowing holes are arranged between the swirl disk 3 and the protective net 4, and electromagnetic valves are arranged in the air blowing holes to block the air blowing holes; electromagnetic valves electrically connected to the central processor are arranged in the air blowing holes. Through the above design, it can be realized that first, the data analysis module can judge the combustion condition of the combustion chamber according to the image information; if it is judged that a blockage is occurring, the central processor drives the electromagnet 10 to be energized to drive the slider 9 to drive the protective side to approach / away from the cyclone disk, so as to first adjust the distance X to adapt to the channel through which the material flows at this time; in addition, the central processor can also drive the electromagnetic valve to open to blow air into the space between the protective net 4 and the cyclone disk; in this way, the air pressure in the space between the protective net 4 and the cyclone disk is less than that around; then, when the high-pressure gas in the combustion chamber is introduced, under the influence of the pressure difference, the blockage removal effect can be improved; and, the central processor can also drive the slider 9 to reciprocally move the protective net 4, which can continuously change the air pressure, thereby further improving the blockage removal effect.

[0030] This burner adopts the measure of "it is better to dredge than to block" for fine materials. The fine materials entering the burner are discharged through the lower discharge part. If the grid density at the front end of the burner is increased, it will have a great impact on the flame. Even if the materials are blocked outside the burner, the flame will also be blocked inside the burner, affecting the use effect of the burner. A cyclone disk is added closely inside the lower discharge port of the burner to prevent the materials from further entering the interior of the burner, and at the same time, it can also purge the front combustion chamber.
