Description

Technical Field

[0001] This utility model relates to the technical field of rotary kiln heating control equipment, specifically to an oil-saving atomizing nozzle. Background Technology

[0002] A rotary kiln is a large-scale continuous thermal equipment that uses the high-temperature environment inside the cylinder and the relative movement of materials to achieve processes such as calcination, roasting, drying, or pyrolysis. It is widely used in industries such as cement, metallurgy, chemicals, and building materials. The internal fuel-saving ignition control device can control the amount of fuel injected and the combustion effect during the ignition and heating process of the rotary kiln.

[0003] In the fuel-saving ignition control device, fuel enters the rotary kiln through an atomizing nozzle for ignition. The atomizing nozzle can efficiently atomize the fuel, allowing the fuel to mix fully with air, thereby improving combustion efficiency and achieving the purpose of saving fuel.

[0004] Because the atomizing nozzle is located inside the rotary kiln, it comes into direct contact with the combustion reaction inside the kiln. During long-term use, combustion causes carbon deposits to form on the nozzle orifice, which hinders the subsequent fuel spraying, reduces the atomization effect of the atomizing nozzle on the fuel, thereby reducing combustion efficiency, increasing fuel consumption, and resulting in the nozzle being unable to work continuously, requiring frequent maintenance and having a short service life. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a fuel-saving atomizing nozzle.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A fuel-saving atomizing nozzle includes a telescopic cleaning component, wherein a fuel nozzle is provided on the outer surface of the telescopic cleaning component; The fuel injector includes an injector body, an injection pipe is fixedly connected to the middle of the bottom end of the injector body, a support shell is fixedly connected to the outer side of the bottom end of the injector body, an air pressure pipe communicating with the injector body is opened inside the injector body, and an airflow utilization component is provided on one side of the inside of the injector body.

[0007] The beneficial effects of this utility model are: it can use the added high-pressure gas to drive the telescopic cleaning component through the airflow utilization component, so that the telescopic cleaning component does not require an additional power source. It can automatically remove carbon deposits at the fuel injection nozzle during the normal operation of the atomizer nozzle, avoid the obstruction of fuel injection by carbon deposits, ensure the stability of atomization effect, reduce fuel consumption, significantly extend the continuous working time of the atomizer nozzle, reduce the number of equipment maintenance and maintenance costs, and reduce the corrosion and wear damage of carbon deposits to the fuel injection pipe, thereby extending the service life of the overall device and reducing equipment replacement costs.

[0008] Furthermore, the airflow utilization component includes a diversion pipe that is opened inside the fuel injector body and connected to the air pressure pipe. An airflow channel is opened below the diversion pipe and connected to it. The bottom end of the airflow channel extends to the outer side of the bottom end of the fuel injector body. The diversion pipe can divert a portion of the high-pressure gas and utilize it through the airflow channel.

[0009] Furthermore, a drive impeller is rotatably connected inside the fuel injector body, the airflow passage passes through one side of the drive impeller, and a solenoid valve is fixedly connected at the connection between the airflow passage and the diversion pipe. The drive impeller can generate rotation by utilizing the high-pressure airflow in the airflow passage, converting the kinetic energy of the gas into mechanical rotational energy.

[0010] Furthermore, the supporting housing includes a housing cylinder fixedly connected to the bottom end of the fuel injector body, and two guide posts are evenly fixedly connected to the inner wall of the housing cylinder. The guide posts guide the movement of the subsequent telescopic cleaning component.

[0011] Furthermore, the telescopic cleaning assembly includes two vertically mirrored driven gears. The opposite sides of the two driven gears are connected to a non-circular transmission bevel gear. One end of the non-circular transmission bevel gear is fixedly connected to the end of the drive impeller near the fuel injection pipe. The non-circular transmission bevel gear meshes with only one driven gear at a time. Since the two driven gears are distributed on the upper and lower sides of the non-circular transmission bevel gear, the two driven gears rotate in different directions when meshing with the non-circular transmission bevel gear.

[0012] Furthermore, a fixing ring is fixedly connected to the inner side of both driven gears. The top end of the fixing ring is rotatably connected to the bottom end of the inner side of the fuel injector body. A telescopic component is fixedly connected to the bottom end of the driven gear below. A cleaning brush head is fixedly connected to the bottom end of the telescopic component. The telescopic component and the cleaning brush head are the execution ends of the cleaning action.

[0013] Furthermore, the telescopic assembly includes a drive cylinder fixedly connected to the bottom end of the driven gear below. Two limiting blocks are fixedly connected to the outer surface of the drive cylinder. A telescopic cylinder is slidably connected to the outer surface of the drive cylinder through the limiting blocks. Two annular guide grooves are formed on the outer surface of the telescopic cylinder. The top end of the telescopic cylinder is fixedly connected to the top end of the cleaning brush head. When the guide post slides along a spiral path in the guide groove, it is simultaneously limited by the limiting blocks, so that the telescopic cylinder can extend and retract along the axial direction of the limiting blocks while rotating with the drive cylinder.

[0014] Furthermore, the guide post is slidably connected to the inside of the guide groove, and the inside of the cleaning brush head is attached to the nozzle of the fuel injection pipe. During the up-and-down movement of the cleaning brush head, it can directly act on the carbon deposits at the nozzle and remove the carbon deposits through physical scraping, thus preventing carbon deposits from clogging the nozzle and affecting the fuel injection and atomization effect.

It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail.

[0022] Example 1 Figure 1 This is a structural diagram of a fuel-saving atomizing nozzle provided in an embodiment of the present utility model. Figure 1 The device includes a telescopic cleaning component 2, on the outer surface of which is provided a fuel nozzle 1. The two are nested together to form an integrated device that can achieve carbon deposit cleaning and efficient atomization, providing basic structural support for the subsequent collaborative work of various components.

[0023] Figure 2 This is a cross-sectional view of the overall structure of this utility model. (See attached image.) Figure 2 As shown, the fuel nozzle 1 includes a fuel nozzle body 11, a fuel injection pipe 14 is fixedly connected to the middle of the bottom end of the fuel nozzle body 11, a support housing 15 is fixedly connected to the outer side of the bottom end of the fuel nozzle body 11, a pneumatic pipe 12 is opened inside the fuel nozzle body 11 to communicate with the fuel nozzle body 11, and an airflow utilization component 13 is provided on one side of the inside of the fuel nozzle body 11.

[0024] The fuel injection pipe 14 is used to deliver fuel into the rotary kiln; the supporting housing 15 provides a base for the installation and limiting of the telescopic cleaning assembly 2; the pneumatic pipe 12 can introduce high-pressure gas to power the atomized fuel and drive the cleaning structure, while the airflow utilization assembly 13 can divert the airflow in the pneumatic pipe 12 for utilization.

[0025] The fuel injector body 11 intermittently injects fuel and can also inject high-pressure gas independently, which is existing technology and will not be explained here.

[0026] Figure 3 This is a schematic diagram of the airflow utilization component of this utility model. Figure 3 As shown, the airflow utilization component 13 includes a diversion pipe 131 that is opened inside the fuel injector body 11 and connected to the air pressure pipe 12. An airflow channel 133 is opened below the diversion pipe 131 and connected to it. The bottom end of the airflow channel 133 extends to the outer side of the bottom end of the fuel injector body 11. A drive impeller 134 is rotatably connected inside the fuel injector body 11. The airflow channel 133 passes through one side of the drive impeller 134. A solenoid valve 132 is fixedly connected at the connection between the airflow channel 133 and the diversion pipe 131.

[0027] As the high-pressure gas enters the pressure pipe 12, a portion is diverted by the diversion pipe 131. The solenoid valve 132 controls the flow and flow rate of the airflow. When the solenoid valve 132 is open, the high-pressure gas flows along the airflow channel 133 through the diversion pipe 131. Since the path of the airflow channel 133 passes through one side of the drive impeller 134, the high-speed airflow impacts the drive impeller 134, causing it to rotate and converting the kinetic energy of the gas into mechanical rotational energy, providing power for the movement of the subsequent cleaning components. The airflow channel 133 eventually extends to the outer side of the bottom of the fuel injector body 11, ensuring that the airflow can be smoothly discharged after the drive impeller 134, avoiding pressure buildup inside the device.

[0028] The solenoid valve 132 can be closed when fuel is injected and opened only when high-pressure gas is injected. The model of solenoid valve 132 is DMV-DLE512 / 11, which is existing technology and will not be explained here.

[0029] Figure 4 This is a sectional view of the entire utility model disassembled. For example... Figure 4As shown, the supporting housing 15 includes a housing cylinder 151 fixedly connected to the bottom end of the fuel injector body 11, and two guide posts 152 are evenly fixedly connected to the inner wall of the housing cylinder 151.

[0030] The outer casing 151 is fixed to the bottom of the fuel injector body 11, and two guide posts 152 evenly distributed on its inner wall will serve as key guiding structures for the subsequent movement of the telescopic cleaning component 2.

[0031] The telescopic cleaning component 2 includes two vertically mirrored driven gears 21. The opposite sides of the two driven gears 21 are connected to a non-circular transmission bevel gear 22. One end of the non-circular transmission bevel gear 22 is fixedly connected to the end of the drive impeller 134 near the fuel injection pipe 14. The non-circular transmission bevel gear 22 only meshes with one driven gear 21 at a time. The inner sides of the two driven gears 21 are fixedly connected to a retaining ring 23. The top end of the retaining ring 23 is rotatably connected to the bottom inner side of the fuel injector body 11. The bottom end of the lower driven gear 21 is fixedly connected to a telescopic component 24. The bottom end of the telescopic component 24 is fixedly connected to a cleaning brush head 26.

[0032] Two driven gears 21, arranged in a mirror image, are rotatably mounted on the bottom inner side of the injector body 11 via a fixed ring 23 connected on the inner side, ensuring stable rotation of the driven gears 21. The irregularly shaped transmission bevel gear 22 meshes with one of the two driven gears 21. When the drive impeller 134 rotates, it can drive the driven gear 21 to rotate through the irregularly shaped transmission bevel gear 22. Since the two driven gears 21 are distributed on the upper and lower sides of the irregularly shaped transmission bevel gear 22, the two driven gears 21 rotate in different directions when meshing with the irregularly shaped transmission bevel gear 22, achieving the effect of reciprocating rotation of the fixed ring 23. The telescopic component 24 and the cleaning brush head 26 constitute the execution end of the cleaning action.

[0033] Example 2 Based on Embodiment 1, the present invention can be further improved as follows: Figure 5 This is a cross-sectional view of the telescopic component assembly of this utility model. (See attached image.) Figure 5 As shown, the telescopic assembly 24 includes a drive cylinder 241 fixedly connected to the bottom end of the driven gear 21. Two limiting blocks 242 are fixedly connected to the outer surface of the drive cylinder 241. A telescopic cylinder 243 is slidably connected to the outer surface of the drive cylinder 241 through the limiting blocks 242. Two annular guide grooves 244 are opened on the outer surface of the telescopic cylinder 243. The top end of the telescopic cylinder 243 is fixedly connected to the top end of the cleaning brush head 26. The guide post 152 is slidably connected to the inner side of the guide groove 244. When the driven gear 21 rotates, the drive cylinder 241 rotates synchronously. The limiting blocks 242 slide along a spiral path in the guide groove 244, driving the telescopic cylinder 243 to extend and retract axially, thereby controlling the cleaning brush head 26 to move up and down, and realizing the cleaning of areas at different heights.

[0034] The drive cylinder 241 rotates synchronously with the driven gear 21 below. Two limiting blocks 242 are embedded in the inner wall of the telescopic cylinder 243, while the guide post 152 is slidably connected to the inner side of the guide groove 244. When the drive cylinder 241 rotates, the guide post 152 slides along the spiral path in the guide groove 244. At the same time, the limiting effect of the limiting blocks 242 allows the telescopic cylinder 243 to extend and retract along the axial direction of the limiting blocks 242 while rotating with the drive cylinder 241. This drives the cleaning brush head 26 to move up and down, cleaning the carbon deposits at the oil injection point of the oil injection pipe 14, achieving full coverage of the cleaning range.

[0035] Figure 6 This is a schematic diagram of the cleaning brush head assembly of this utility model. Figure 6 As shown, the inner side of the cleaning brush head 26 is attached to the nozzle of the fuel injection pipe 14.

[0036] The inner side of the cleaning brush head 26 fits tightly against the nozzle of the fuel injection pipe 14, allowing the cleaning brush head 26 to directly act on the carbon deposits at the nozzle during its up-and-down movement. The carbon deposits are removed through physical scraping, preventing them from clogging the nozzle and affecting fuel injection and atomization.

[0037] The cleaning brush head 26 is made of silicon carbide fiber, which can withstand temperatures of 800-1400℃ and can clean impurities from the brush head when the airflow is sprayed out.
