Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a multi-channel mixed fuel burner. Background Technology

[0002] A burner is a device that mixes fuel and air in a certain way for combustion. It is applicable to fields such as building materials, chemicals, and metallurgy. In the building materials field, burners are usually used in cement rotary kilns to calcine cement clinker.

[0003] A novel multi-channel burner, disclosed in CN221504997U, includes a mounting base. The mounting base has an outer secondary air duct inside, an inner secondary air duct inside the outer secondary air duct, a coal flow air duct inside the inner secondary air duct, and a central air duct inside the coal flow air duct. A pipe 1 passes through the right end of the inner wall of the outer secondary air duct, a pipe 2 passes through the right end of the inner wall of the inner secondary air duct, a pipe 3 passes through the right end of the inner wall of the coal flow air duct, and a pipe 4 passes through the right wall of the central air duct. The left wall of the coal flow air duct has evenly distributed grooves, each groove having a rotating ball 1 rotatably connected inside, and each rotating ball 1 having a nozzle passing through its interior.

[0004] Although the above-mentioned device filters impurities from the air entering the device by setting up a filter screen to improve the combustion effect, the device requires multiple filters to be installed in pipes one, two and four respectively. This results in the need to disassemble and install multiple filters one by one during cleaning, which is cumbersome and greatly reduces the cleaning efficiency of the filters. It is difficult to meet the needs of convenient equipment maintenance in actual production. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-5 A multi-channel mixed fuel burner includes a combustion body and a housing 8. An outer secondary air duct 1 is disposed inside the combustion body. The top of the outer secondary air duct 1 is connected to a first pipe 5. An inner secondary air duct 2 is disposed inside the outer secondary air duct 1. The bottom of the inner secondary air duct 2 is connected to a second pipe 6. A kerosene air duct 3 is disposed inside the inner secondary air duct 2. The top of the kerosene air duct 3 is connected to a third pipe 7. The end of the kerosene air duct 3 furthest from the inner secondary air duct 2 is connected to a central air duct 4. The other end of the central air duct 4 is fixedly inserted through the housing 8. The other ends of the first pipe 5, the second pipe 6, and the third pipe 7 are all fixedly inserted into the inside of the housing 8. Three connecting pipes 9 are connected to the outer end of the housing 8, and the three connecting pipes 9 correspond to the first pipe 5, the second pipe 6, and the third pipe 7, respectively. The outer secondary air duct 1, the inner secondary air duct 2, and the kerosene air duct 3 are made of high-temperature resistant alloy material, which can effectively resist high-temperature corrosion during combustion. The connection between each pipe and the air duct is achieved by welding to ensure a tight seal and prevent fuel or air leakage.

[0026] The housing 8 is internally connected to a second baffle 22, and the housing 8 is internally slidably connected to a first baffle 10, with the opposite sides of the first baffle 10 abutting against the second baffle 22. The first baffle 10 is internally equipped with three filters 12, which are located between the connecting pipe 9 and the first pipe 5, between the connecting pipe 9 and the second pipe 6, and between the connecting pipe 9 and the third pipe 7, respectively. The outer end of the first baffle 10 is fixedly equipped with an mounting plate 11. The three filters 12 are made of stainless steel wire mesh, and the pore size is customized according to actual usage requirements. They can effectively filter dust and impurities in the air. After the first baffle 10 is installed inside the housing 8, the ends of the connecting pipe 9 and the first pipe 5 that are close to each other will be tightly attached to both sides of the filters 12 to ensure accurate flow (the same applies to the second pipe 6 and the third pipe 7).

[0027] A self-locking mechanism is provided on the front of the housing 8. The self-locking mechanism includes a U-shaped locking plate 14 connected to the front of the housing 8. A limiting block 13 is slidably connected inside the U-shaped locking plate 14, and the limiting block 13 is connected to the mounting plate 11. The limiting block 13 has an inclined groove 17 and a limiting hole 18 inside, and the limiting hole 18 communicates with the inclined groove 17. The slope of the inclined groove 17 has been optimized by grinding to allow the limiting rod 16 to slide smoothly when squeezed, avoiding jamming. A horizontal sliding groove is provided in the U-shaped locking plate 14 for the limiting block 13 to slide.

[0028] A first spring 15 is connected to one side of the U-shaped card plate 14, and a pull plate is connected to the other end of the first spring 15. A limit rod 16 is connected to the outer surface of the pull plate, and the other end of the limit rod 16 is slidably inserted into the inside of the limit hole 18. The pull plate and the limit rod 16 are integrally formed to ensure uniform force. The diameter of the limit rod 16 is matched with the diameter of the limit hole 18 to ensure that the limit rod 16 can be smoothly inserted into or removed from the limit hole 18.

[0029] The front of the housing 8 is provided with an ejection mechanism, which includes a groove inside the U-shaped clamping plate 14. A slide plate 20 is slidably connected inside the groove. A second spring 21 is connected to the side of the slide plate 20 closest to the housing 8, and the other end of the second spring 21 is connected to the inner wall of the groove. A top plate 19 is connected to the top of the limiting block 13. The top plate 19 is slidably connected inside the groove and is used to contact the side of the slide plate 20 away from the housing 8. The size of the groove matches the size of the slide plate 20 and the top plate 19 to ensure that the slide plate 20 and the top plate 19 slide smoothly within the groove. This groove is connected to the horizontal groove in the U-shaped clamping plate 14 used for the sliding of the limiting block 13 to ensure reliable operation.

[0030] In operation, when installing the filter screen 12, the first baffle 10 is inserted into the internal sliding hole of the housing 8. At this time, the limiting block 13 moves synchronously with the first baffle 10. The inclined groove 17 in the limiting block 13 contacts the limiting rod 16. The inclined surface of the inclined groove 17 presses against the limiting rod 16, causing the limiting rod 16 to move outward and stretch the first spring 15. When the first baffle 10 is inserted to its maximum extent, the limiting hole 18 is concentric with the limiting rod 16. Under the reset action of the first spring 15, the limiting rod 16 is inserted into the limiting hole 18, realizing the automatic self-locking of the first baffle 10. Installation can be completed without additional operation.

[0031] When disassembling the filter screen 12, pull the limiting rod 16 outward to disengage it from the limiting hole 18. At this time, the top plate 19 is no longer blocked by the limiting rod 16. The second spring 21 pushes the sliding plate 20 to slide outward in the slide groove. The sliding plate 20 pushes the limiting block 13 and the first baffle 10 outward through the top plate 19, thereby popping the first baffle 10, which integrates three filter screens 12, out of the housing 8. This facilitates the one-time cleaning of the three filter screens 12 and significantly improves the efficiency of filter screen disassembly, assembly, and cleaning.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
