Description

Technical Field

[0001] This utility model belongs to the field of incinerator technology, specifically relating to an incinerator flue cleaning device. Background Art

[0002] During operation, incinerators accumulate a large amount of hardened scale on the water-cooled walls of their flues. This scale not only reduces the heat exchange efficiency of the boiler flue but also negatively impacts production if left uncleaned for a long time. Current technologies struggle with cleaning the flue's inner walls, often relying on manual labor, which is time-consuming, labor-intensive, and poses safety risks. Furthermore, it causes wear and tear on the flue walls, affecting their lifespan. Therefore, a new incinerator flue cleaning device is needed to address these technical problems. Utility Model Content

[0003] To address the aforementioned deficiencies in existing technologies, this utility model provides an incinerator flue cleaning device, comprising a flue with a water-cooled wall on its inner wall; multiple inlets at the top of the flue, with guide tubes fixed at each inlet; a truss at the top of the flue cooperating with each guide tube; the truss being fixed to the top of the flue by columns; a slide rail on the truss; a U-shaped frame with an opening facing downwards fixed on the slider of the slide rail; a rotating roller between two vertical frames of the U-shaped frame; the two ends of the rotating roller being rotatably connected to the corresponding vertical frame via bearings; a forward / reverse motor connected to one end of the rotating roller, which is fixed to the vertical frame; a water guide pipe wound around the rotating roller; one end of the water guide pipe passing through the center of the rotating roller and connected to a water inlet pipe via a rotary joint; and a water spray head connected to the other end of the water guide pipe. The water spray head cooperates with the guide tubes, and when the rotating roller moves to a guide tube, the water spray head aligns vertically with the guide tube.

[0004] Furthermore, the top of the duct is provided with a tapered tube that is wider at the top and narrower at the bottom. The tapered tube facilitates better entry of the water spray head into the duct and into the flue along the duct.

[0005] Furthermore, the inlet is provided in two rows, the truss is U-shaped, and the slide rail is a U-shaped electric slide rail. The U-shaped electric slide rail is arranged vertically and vertically corresponding to the two rows of inlets, so that when the rotating roller slides along the U-shaped electric slide rail, the water spray head can pass above each guide tube in sequence, so that when the rotating roller rotates, the water spray head descends into the guide tube and enters the flue to spray water onto the inner wall of the flue.

[0006] Furthermore, the spray head is a rotating nozzle. The rotating nozzle design allows for more uniform and efficient water spraying onto the inner wall of the flue.

[0007] Furthermore, the water guide pipe is equipped with a pipe-managing device, which includes a lead screw, a guide rod, and a slider. Horizontal supports are fixedly connected to the lower ends of both vertical frames. The two ends of the lead screw are rotatably connected to the corresponding horizontal supports via bearings. One end of the lead screw is connected to a forward / reverse motor. The two ends of the guide rod are fixedly connected to the corresponding horizontal supports. The slider is threaded into the lead screw and has a guide hole through which the guide rod passes. A limiting frame is also provided on the slider, with two cooperating limiting rollers. The water guide pipe passes between the two limiting rollers and connects to the spray head. This design helps to manage the water guide pipe as the spray head descends or rises, preventing the water guide pipe from becoming tangled and disordered on the rotating roller.

[0008] This utility model also includes other components that enable the incinerator flue cleaning device to function properly, such as the control components for the forward and reverse motor and the control components for the U-shaped electric slide rail, which are all conventional technologies in the field. Furthermore, devices or components not limited in this utility model, such as the U-shaped electric slide rail, rotary joint, rotary nozzle, and lead screw, all employ conventional technologies and equipment in the field.

[0009] Working Principle: When cleaning the inner wall of the flue is required, the electric slide rail causes the slider to move the rotating roller to the corresponding guide tube. The forward and reverse motor drives the rotating roller to rotate, causing part of the water guide tube wrapped around the roller to detach from the roller. The water nozzle moves down and enters the flue through the guide tube. Then, water is introduced through the inlet pipe to the guide pipe, and the water nozzle sprays water onto the inner wall of the flue, washing away the dirt on the inner wall. When the dirt that is firmly stuck to the inner wall of the flue is wetted, due to the high temperature of the flue, the dirt cracks due to the principle of thermal expansion and contraction caused by the interaction of the water-cooled wall and the water sprayed from the nozzle, making it easier to rinse clean. After cleaning this part of the flue, the forward and reverse motor rotates in the opposite direction, wrapping the water guide tube around the rotating roller again. The water nozzle retracts from the guide tube, and the electric slide rail drives the rotating roller to the next guide tube. The above operation is repeated to complete the cleaning of the dirt on the inner wall of the corresponding flue.

[0010] The beneficial effects of this utility model are: it can efficiently clean the dirt on the inner wall of the flue, the cleaning process is highly automated and safe, and it reduces damage to the inner wall of the flue. Attached Figure Description

The two ends of the rotating roller 8 are rotatably connected to the corresponding vertical frame via bearings. One end of the rotating roller 8 is connected to a forward / reverse motor 12, which is fixed on the vertical frame. A water guide pipe 9 is wound around the rotating roller 8. One end of the water guide pipe 9 passes through the center of the rotating roller 8 and is connected to a water inlet pipe 13 via a rotary joint 11. The other end of the water guide pipe 9 is connected to a spray head 10. The spray head 10 cooperates with the guide pipe. When the rotating roller moves to a guide pipe, the spray head aligns vertically with the guide pipe. The pipe management device can prevent the water guide pipe 9 wound on the rotating roller 8 from becoming tangled.

[0019] The top of the duct is provided with a tapered tube 5 that is wider at the top and narrower at the bottom. The tapered tube 5 facilitates the better entry of the spray head 10 into the duct and into the flue 1 along the duct.

[0020] The inlet has two rows, the truss 2 is U-shaped, and the slide rail is a U-shaped electric slide rail 3. The U-shaped electric slide rail 3 is arranged vertically and vertically with the two rows of inlets, so that when the rotating roller 8 slides along the U-shaped electric slide rail 3, the water spray head 10 can pass above each guide tube in sequence, so that when the rotating roller 8 rotates, the water spray head 10 descends into the guide tube and enters the flue 1 to spray water onto the inner wall of the flue 1.

[0021] Example 2

[0022] The difference between this embodiment and Embodiment 1 is that the water spray head 10 is a rotating nozzle. The rotating nozzle design allows for more uniform and efficient water spraying onto the inner wall of the flue 1; otherwise, it is the same as Embodiment 1. The rotating nozzle is existing technology, and its structure and principle will not be described in detail here.

[0023] Example 3

[0024] like Figure 1-2 As shown, the difference between this embodiment and Embodiment 2 is that the water guide pipe is equipped with a pipe-managing device. This device includes a lead screw 15, a guide rod 16, and a slider 17. The lower ends of both vertical frames are fixedly connected to horizontal supports 14. The two ends of the lead screw are rotatably connected to the corresponding horizontal supports via bearings. One end of the lead screw is connected to a second reversible motor 20, which is fixed to the horizontal support. The two ends of the guide rod are fixedly connected to the corresponding horizontal supports. The slider 17 is threadedly engaged with the lead screw. A guide hole is provided on the slider 17, through which the guide rod passes. A limiting frame 18 is also provided on the slider, with two cooperating limiting rollers 19. Each limiting roller has a groove matching the water guide pipe. The water guide pipe 9 passes between the two limiting rollers and connects to the spray head 10. This arrangement can manage the water guide pipe when the spray head descends or rises, preventing the water guide pipe wrapped around the rotating roller from becoming tangled and disordered. The rest is the same as in Embodiment 2.

[0025] The U-shaped electric slide rail, rotating nozzle, forward and reverse motor, and rotary joint in the above embodiments are all existing technologies. This application does not make any improvements to them, but only utilizes their existing functions. For their specific structure and principle, please refer to the product manual or existing technical data, which are all existing technologies.
