Description

Technical Field

[0001] The invention relates to the technical field of industrial furnace cleaning, and in particular to a cleaning device for an industrial furnace. Background Art

[0002] Industrial furnaces are thermal equipment that use heat from fuel combustion or electrical energy conversion to heat materials or workpieces in industrial production. During the use of industrial furnaces, scale is easily accumulated on the inner wall, which will reduce the heat conduction efficiency, increase energy consumption, and may cause uneven temperature. Therefore, it is particularly important to clean the industrial furnace regularly, which can extend the service life of the furnace and reduce maintenance costs.

[0003] At present, the main cleaning methods for industrial furnaces are: high-pressure flushing, using a high-pressure water gun to flush the inner wall of the furnace. High-pressure water washing is an effective cleaning method for removing scale, residues and other dirt in the furnace. However, this flushing method requires people to always observe the flushing position in the furnace, which is prone to leakage and poor cleaning safety. At the same time, the flushed dirt and flushing water will accumulate at the bottom of the industrial furnace, and the subsequent manual discharge of the cleaning water in the furnace is required, which makes cleaning cumbersome. In the literature (application number: CN202020935411.0), an automatic cleaning device for industrial furnaces is disclosed, which cleans the industrial furnace by evenly spraying the cleaning water and using a brush. The device is also unable to discharge the cleaning liquid while cleaning, and the brushing force cannot be adjusted, so stubborn dirt is difficult to clean. Summary of the invention

[0010] Furthermore, the radius of the driving wheel is smaller than the radius of the driven wheel.

[0011] Furthermore, a guide column is provided at the bottom of the lifting frame, a guide hole is opened at the top of the frame, the guide column is inserted into the guide hole, and a universal wheel is provided at the bottom of the frame.

[0012] Furthermore, the thread pitch of the driving part is the same as the flushing width of the nozzle.

[0013] Furthermore, the driving assembly includes a pull rope, which is fixedly connected to the left side of the support rod.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present invention utilizes a high-pressure cleaning machine to pump high-pressure water into the scraping part through a water inlet pipe, and the scraping part expands into a stable ring shape and fits the inner wall of the industrial furnace. The high-pressure water is then sprayed out through a drain pipe and a nozzle. The sprayed high-pressure water flushes the inner wall of the industrial furnace. The device is then pulled outward by a driving component, and the nozzle moves relative to the inner wall of the industrial furnace. At the same time, the scraping part scrapes the flushed inner wall of the industrial furnace. Then, through the coordinated use of the water retaining part, the cleaning component can scrape out the cleaning water in the industrial furnace, with high cleaning efficiency and good cleaning effect.

[0020] 2. The present invention uses high-pressure water flow to expand the scraping part and tightly adhere to the inner wall of the industrial furnace. When the water pressure increases, the friction between the scraping part and the inner wall of the industrial furnace is too large, and the driving component drives the support rod and the outer frame to move relative to the scraping part. The elastic connecting part is stretched. At this time, the nozzle moves relative to the scraping part. Under the action of the transmission rope, the nozzle swings downward, and the flushing angle of the nozzle is reduced, changing from vertical flushing to tangential flushing, which can improve the flushing effect. At the same time, when the water pressure is too high, the nozzle swings toward the water retaining part, which can prevent the high pressure from damaging the industrial furnace, and the flushing stability is high.

[0021] 3. The present invention can fold and store the device through the arrangement of the external frame and the support rods, making it easy to carry. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] Embodiment 1, as Figure 1-Figure 9 As shown, a cleaning device for an industrial furnace includes a high-pressure cleaning machine and a support rod 3. The support rod 3 is composed of a screw portion 31 and a hinge portion 32. The outer side of the hinge portion 32 is hinged with multiple groups of outer skeletons 4 in an annular manner, preferably ten groups. The outer side of the outer skeleton 4 is provided with a hinge 41. The outer side of the screw portion 31 is threadedly connected with an adjusting nut 5. The right side of the adjusting nut 5 is rotatably installed with a hinge head 51. The hinge head 51 is sleeved on the screw portion 31. The outer side of the hinge head 51 is hinged with multiple groups of support rods 6 in an annular manner. The other end of the support rod 6 is hinged with the hinge 41.

[0035] The cleaning assembly 7 also includes a cleaning component 7, which includes a cleaning scraper 71 and a water retaining portion 72. An elastic connector 42 is provided on the right side of the outer frame 4, and the elastic connector 42 is fixedly connected to the cleaning scraper 71. The cleaning scraper 71 is designed in an annular shape, and the cleaning scraper 71 is composed of an outer braided layer 711 and an inner rubber layer 712. A plurality of cleaning scraper sheets 713 are bonded to the outer ring of the inner rubber layer 712, and a plurality of water inlets 74 and drains 75 are provided in the outer ring of the cleaning scraper 71.

[0036] A mounting frame 43 is fixedly installed on the outside of the exoskeleton 4, and a nozzle 44 is rotatably installed inside the mounting frame 43. The nozzle 44 is connected to the drain port 75 through a drain pipe 49, and the nozzle 44 is connected to the scraper part 71 through a transmission rope 48. A pipe hole 34 is opened inside the support rod 3, and a water inlet pipe 8 is inserted through the pipe hole 34. The water inlet pipe 8 is connected to the high-pressure cleaning machine. A plurality of branch pipes 82 are arranged on the right side of the water inlet pipe 8, and the branch pipes 82 are connected to the water inlet 74. A driving assembly is arranged on the left side of the support rod 3.

[0037] The water retaining part 72 and the outer braided layer 711 in the present invention are both made of nylon, which has high strength and good waterproof effect. The scraper sheet 713 is made of soft cloth, which is not easy to scratch the inner wall of the industrial furnace. The elastic connector 42 is made of nitrile rubber, which has good wear resistance and elasticity.

[0038] During cleaning, the device is extended into the innermost part of the industrial furnace, and then the adjusting nut 5 is rotated. The adjusting nut 5 is moved away from the hinged part 32 under the action of the screw part 31, and the adjusting nut 5 drives the hinged head 51 to move away from the hinged part 32. The hinged head 51 drives the outer frame 4 to unfold through the support rod 6. The outer frame 4 drives the cleaning component 7 to open through the elastic connecting piece 42. Then the high-pressure cleaning machine is started, and high-pressure water enters the cleaning part 71 through the water inlet pipe 8. The cleaning part 71 expands. Under the restriction of the outer braided layer 711, the inner rubber layer 712 can only expand toward the inner wall of the industrial furnace. The inner rubber layer 712 presses the cleaning scraping sheet 713 against the inner wall of the industrial furnace, and then the high-pressure water is flushed toward the inner wall of the industrial furnace through the drain pipe 49 and the nozzle 44. It is a high-pressure water flow, which will first fill the cleaning and scraping part 71 to ensure that the cleaning and scraping part 71 has the same internal pressure as the drain pipe 49 and the water inlet pipe 8. Since multiple groups of nozzles 44 are provided and the multiple groups of nozzles 44 are distributed in a ring shape, the inner wall of the industrial furnace can be completely washed, and then the support rod 3 is driven to move to the outside of the industrial furnace through the driving assembly, and the support rod 3 drives the outer frame 4 to move, and the outer frame 4 drives the cleaning and scraping part 71 to move through the elastic connecting piece 42. The cleaning and scraping part 71 scrapes the washed inner wall of the industrial furnace, and the cleaning liquid accumulated at the bottom of the industrial furnace can be pushed to the outside of the industrial furnace through the setting of the water retaining part 72. When the device is pulled out of the industrial furnace, the cleaning of the inner wall of the industrial furnace is completed, and the cleaning water can be pushed out of the industrial furnace at the same time, and the cleaning steps are simple;

[0039] When the dirt on the inner wall of the industrial furnace is serious, the water pressure of the flushing water is increased at this time, but excessive water pressure is easy to damage the fireproof material on the inner wall of the industrial furnace. Therefore, when the flushing water pressure of the device of the present invention is increased, the pressure inside the scraper part 71 increases, and the scraper part 71 increases the friction between the scraper sheet 713 and the inner wall of the industrial furnace. The driving component drives the support rod 3 to move toward the outside of the industrial furnace, and the support rod 3 drives the outer frame 4 to move. The outer frame 4 drives the scraper part 71 to move through the elastic connecting piece 42. Due to the increase in friction, the stretching length of the elastic connecting piece 42 increases, and the distance between the scraper part 71 and the nozzle 44 increases. The scraper part 71 passes The transmission rope 48 drives the nozzle 44 to swing downward, and the flushing angle between the nozzle 44 and the inner wall of the industrial furnace is reduced, and gradually changes from vertical to the inner wall of the industrial furnace to tangential to the inner wall of the industrial furnace, the flushing distance is increased, and at the same time, the vertical flushing force directly acting on the inner wall of the industrial furnace is reduced, which can prevent the inner wall of the industrial furnace from being damaged. However, a flushing force tangential to the inner wall of the industrial furnace will be generated, which can improve the flushing effect. Therefore, through the arrangement of the present invention, while improving the flushing effect, it can prevent the fireproof material of the inner wall of the industrial furnace from being damaged. In the actual pressure control process, it is easy to make mistakes. Through the uninventive arrangement, this situation can be effectively prevented from occurring, and the use safety is high.

[0040] Furthermore, a quick-connect connector 81 is provided at the left end of the water inlet pipe 8 for easy connection.

[0041] Embodiment 2, based on the above embodiment, provides a driving component structure:

[0042] like Figure 1-Figure 9 As shown, the driving assembly includes a frame 1, a lifting hole is provided on the top of the frame 1, a threaded hole 11 is provided on the left side of the frame 1, the threaded hole 11 is connected with the lifting hole, a locking bolt 12 is connected to the inner thread of the threaded hole 11, a crank is provided on the left side of the locking bolt 12, a locking plate 21 is slidably connected to the inner part of the lifting hole, a lifting frame 2 is fixedly connected to the top of the locking plate 21, a driving wheel 25 and a driven wheel 26 are rotatably installed on the right side of the lifting frame 2, the driving wheel 25 is meshed with the driven wheel 26, and the lifting frame 2 is lifted. A driving nut 23 is provided on the left side of the frame 2, and a driving part 33 is provided on the left side of the support rod 3. The driving part 33 penetrates the driven wheel 26 and is threadedly connected to the driving nut 23. A driving motor 24 is fixedly installed on the right side of the lifting frame 2. The output end of the driving motor 24 is fixedly connected to the driving wheel 25. A guide groove 35 is provided on the outer side of the driving part 33, and an inner guide protrusion 27 is provided on the inner side of the driven wheel 26. The inner guide protrusion 27 is slidably connected in the guide groove 35. A pipe hole 34 is also provided inside the driving part 33.

[0043] When cleaning, loosen the locking bolt 12 so that the lifting frame 2 can be lifted and lowered freely without restriction, extend the device into the innermost part of the industrial furnace, and then rotate the adjusting nut 5. The adjusting nut 5 moves away from the hinged part 32 under the action of the screw part 31. The adjusting nut 5 drives the hinged head 51 away from the hinged part 32. The hinged head 51 drives the outer frame 4 to unfold through the support rod 6. The outer frame 4 drives the cleaning component 7 to open through the elastic connecting piece 42. Then start the high-pressure cleaning machine. High-pressure water enters the scraping part 71 through the water inlet pipe 8. The scraping part 71 expands. Under the restriction of the outer braided layer 711, the inner rubber layer 712 can only expand toward the inner wall of the industrial furnace. The inner rubber layer 712 presses the scraping sheet 713 against the inner wall of the industrial furnace. At this time, the device is located in the center of the industrial furnace. Then tighten the locking bolt 12. The locking bolt 12 clamps the locking plate 21, and the lifting frame 2 is fixed, completing the installation. The position is positioned, and then the driving motor 24 is energized by controlling the driving motor 24, the driving motor 24 drives the active wheel 25 to rotate, the active wheel 25 drives the driven wheel 26 to rotate, the driven wheel 26 drives the driving part 33 to rotate through the inner guide protrusion 27 and the guide groove 35, the driving part 33 moves toward the outside of the industrial furnace under the action of the driving nut 23, the driving part 33 drives the support rod 3 to move toward the outside of the industrial furnace, the support rod 3 drives the exoskeleton 4 to move, the exoskeleton 4 drives the nozzle 44 to move, at this time, the flushing path of the nozzle 44 is spiral, which can more completely flush the inner wall of the industrial furnace, and the exoskeleton 4 drives the scraping part 71 to move through the elastic connecting piece 42, and the scraping path of the scraping part 71 is also spiral, so that when the scraping part 71 moves, the shape is more stable and the scraping effect is better, and at the same time, the cleaning liquid can be better pushed to the outside of the industrial furnace. This embodiment is more suitable for large cylindrical industrial furnaces.

[0044] Furthermore, a guide column 22 is provided at the bottom of the lifting frame 2, a guide hole is opened at the top of the frame 1, the guide column 22 is inserted into the guide hole, and a universal wheel is provided at the bottom of the frame 1. The setting of the guide column 22 improves the lifting stability of the lifting frame 2, and the setting of the universal wheel facilitates the movement of the device.

[0045] Embodiment 3, based on the above embodiment, further includes that the radius of the driving wheel 25 is smaller than the radius of the driven wheel 26. This design can amplify the torque, generate a greater output force, and have higher control accuracy.

[0046] Embodiment 4, based on the above embodiment, further includes that the thread pitch of the driving part 33 is the same as the flushing width of the nozzle 44. Through this design, the flushing efficiency can be maximized when the package is completely flushed.

[0047] Embodiment 5, based on the above embodiment, provides another driving component structure:

[0048] like Fig.10 As shown, the driving assembly includes a pull rope 9, which is fixedly connected to the left side of the support rod 3.

[0049] Compared with the second embodiment, this embodiment has a simple structure and is more suitable for small cylindrical industrial furnaces. When cleaning, the pull rope 9 is manually pulled to slowly pull the device out of the industrial furnace.

[0050] Embodiment 6, on the basis of the above embodiment, further includes: a worm 46 is rotatably installed inside the mounting frame 43, a worm wheel 45 is fixedly installed on the outside of the nozzle 44, the worm wheel 45 is meshed with the worm 46, a torsion spring is provided between the worm 46 and the mounting frame 43, a reel 47 is fixedly installed on the outside of the worm 46, and the reel 47 is connected to the scraping part 71 through a transmission rope 48.

[0051] When the flushing water pressure is increased, the pressure inside the scraper part 71 increases, and the scraper part 71 increases the friction between the scraper sheet 713 and the inner wall of the industrial furnace. The driving assembly drives the support rod 3 to move toward the outside of the industrial furnace, and the support rod 3 drives the outer frame 4 to move. The outer frame 4 drives the scraper part 71 to move through the elastic connecting piece 42. Due to the increase in friction, the stretching length of the elastic connecting piece 42 increases, and the distance between the scraper part 71 and the nozzle 44 increases. The scraper part 71 drives the reel 47 to rotate through the transmission rope 48, and the reel 47 drives the worm 46 to rotate. The worm 46 drives the worm wheel 45 to rotate, and the worm wheel 45 drives the nozzle 44 to swing downward. When the scraper part 71 and the outer frame 4 When the distance between them decreases, the transmission rope 48 relaxes, and the worm 46 reverses under the action of the torsion spring. The worm 46 drives the nozzle 44 to swing upward through the worm wheel 45, so as to stably control the swing angle of the nozzle 44, and uses the worm gear system as a transmission setting. The worm gear transmission system is usually unidirectional, that is, the worm 46 can drive the worm wheel 45 to rotate, but the worm wheel 45 cannot drive the worm 46 in the reverse direction. This is because the oblique angle generated by the helical teeth of the worm 46 when meshing makes it difficult for the worm wheel 45 to easily drive the worm 46, so the nozzle 44 itself cannot change its angle, ensuring that the nozzle 44 will not change its angle due to the reaction force of flushing during flushing, and the flushing is stable.

[0052] Embodiment 7, based on the above embodiment, further includes that the water retaining portion 72 is designed to be conical, which has a better water retaining effect and can better push the cleaning water out of the industrial furnace.

[0053] Furthermore, an air inlet 73 is provided in the middle of the water retaining portion 72. Since negative pressure is easily generated inside the industrial furnace when the device is pulled out of the industrial furnace, the setting of the air inlet 73 can eliminate the influence of negative pressure on the pulling out of the device.

[0054] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
