Description

Technical Field

[0001] This utility model relates to the field of oil gun technology, specifically to an oil gun atomizer for bottom blowing furnace heating. Background Technology

[0002] The old-style main burner has a diameter of 300mm, making it cumbersome and laborious to use, requiring at least two people to operate. It also requires a separate 18kW fan, consuming considerable electricity. Furthermore, when slagging during production reduces the burner's orifice size, it becomes unusable. There is significant room for improvement in diesel atomization efficiency and raw material combustion efficiency. Therefore, considering ease of operation, applicability, energy saving, environmental protection, and atomization effect, this application provides an oil gun atomizer for bottom-blown furnace heating. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing an oil gun atomizer for bottom-blown furnace heating, thereby resolving the problems mentioned above.

[0004] This utility model provides an oil gun atomizer for bottom-blown furnace heating, including:

[0005] The main pipe has an end cover plate welded to one end and an air outlet at the other end.

[0006] The oil gun tube is located inside the main pipe and passes through and is fixed to the end cover plate;

[0007] Compressed air duct, fixedly installed on end cover plate and connected to main pipe;

[0008] The oxygen tube is fixedly mounted on the end cap plate and connected to the main pipe, and a valve is installed on it.

[0009] The blades are evenly distributed circumferentially inside the air outlet.

[0010] Compressed air pipe and oxygen pipe are located on both sides of the oil gun pipe.

[0011] Preferably, the diameter of the compressed air duct is 15-25mm. The diameter of the oxygen duct is 15-25mm. The diameter of the oil gun duct is 75-85mm. The diameter of the main pipe is 140-160mm. The valve is a manual valve.

[0012] Preferably, one end of the blade is fixed to the inner wall of the air outlet, and the other end of the blade is fixed to the oil gun pipe. The blade is inclined inside the air outlet. A handle is provided on the main pipe, and the handle has a V-shaped structure.

[0013] Compared with existing technologies, it has the following beneficial effects:

[0014] 1. The atomizer of this application can adjust the ratio of oxygen and compressed air according to the atomization effect of the fuel gun and the combustion situation, so as to improve the atomization effect of diesel fuel, ensure more complete combustion, and make the heating safer.

[0015] 2. The atomizer of this application is exquisite and compact, weighing less than 10kg, which is only 1 / 5 of the original main burner, making it more convenient and lightweight to use. In addition, the manufacturing process is simple and the processing cost is lower.

[0016] 3. The atomizer in this application does not need to be connected to an 18kW centrifugal fan; it only needs to utilize surplus compressed air, which is both energy-saving and environmentally friendly.

[0017] 4. The main burner orifice diameter is 300mm. Due to slag formation during the production process, the orifice diameter becomes smaller, making it impossible to insert a 300mm diameter main burner. However, the atomizer in this application has a diameter of 150mm and can still be used normally. In addition, it can be used at temperatures ranging from 300-1100℃, making it more versatile and practical. Attached Figure Description

[0033] Oxygen pipe 4 is fixedly mounted on end cap plate 11 and connected to main pipe 1, and a valve 6 is installed on it.

[0034] Blades 5 are evenly distributed circumferentially within the air outlet 12. The placement of blades 5 in the air outlet 12 assists in the dispersion and atomization effect. Specifically, there are four blades 5.

[0035] Compressed air pipe 3 and oxygen pipe 4 are located on both sides of oil gun pipe 2. The oil and gas coming out of oil gun pipe 2 are mixed to form primary atomized oil. The inner cavity between main pipe 1 and oil gun pipe 2 is surrounded by air and oxygen, which can be used for secondary atomization and combustion assistance. The ratio of oxygen and air can be adjusted according to the actual temperature requirements.

[0036] This application involves placing the fuel gun atomizer in the main burner hole, inserting the fuel gun into the fuel gun atomizer, and after igniting the fuel gun, adjusting the ratio of oxygen and compressed air according to the diesel atomization and combustion conditions to make the diesel atomization effect more uniform and thorough, ensuring more complete combustion and safer heating.

Valve 6 is a manual valve 6, which can adjust the oxygen flow rate. Furthermore, a manual valve 6 is also provided on the compressed air pipe 3 for adjusting the compressed air flow rate. The compressed air pipe 3 is connected to the compressor or compressed air port through a pipeline.

[0038] See Figure 3 One end of the blade 5 is fixed to the inner wall of the air outlet 12, and the other end of the blade 5 is fixed to the oil gun tube 2 so as to support one end of the oil gun tube 2.

[0039] See Figure 1 The main pipe 1 is equipped with a handle 7, which has a V-shaped structure.

[0040] As another embodiment of this application, such as Figure 6 and Figure 7 As shown, the oil gun tube 2 of this application is provided with external threads, and a connecting threaded tube 8 is provided in the middle of the end cover plate 11. The oil gun tube 2 is detachably fixed to the connecting threaded tube 8 through the external threads. Further, multiple blades 5 are fixed to the sleeve 9, and the sleeve 9 is provided with internal threads. The end of the oil gun tube 2 is provided with external threads that connect with the internal threads of the sleeve 9, so as to fix both ends of the oil gun tube 2 to both ends of the main pipe 1. This embodiment provides a technical solution for the detachable connection of the oil gun tube 2 to the main pipe 1, so as to facilitate the replacement, maintenance, and cleaning of the oil gun tube 2 during use.
