Description

Technical Field

[0001] The utility model relates to the technical field of boilers, and specifically discloses a cleaning tool for waste heat boiler pipelines. Background Art

[0002] In the process of chemical production, the heat energy generated by chemical reactions is usually recovered by a waste heat boiler, and the heat energy generated by chemical reactions is fully utilized through the generated steam. After the existing chemical waste heat boiler operates for a period of time, the internal pipelines need to be cleaned. On the one hand, it is to avoid pipeline blockage, and on the other hand, it can ensure the heat exchange performance of the boiler and improve the heat energy utilization rate.

[0003] When cleaning the waste heat boiler pipeline, the operator first opens the flue gas chambers at both ends of the boiler, and then uses a self-made simple tool (composed of a long rod and a push scraper welded together) to extend into the pipeline one by one, and then forcefully pushes the tool along the central axis of the pipeline. During the pushing process, the impurities accumulated inside and the dirt attached to the inner wall of the pipeline are pushed out from the other end to complete the pipeline cleaning process. The cleaning of the pipelines in the above traditional waste heat boiler not only has a large labor intensity and low operation efficiency, but also when manually pushing the tool in the pipeline, it is impossible to ensure that it moves along the central axis of the pipeline, resulting in the push scraper at the front end of the tool being unable to scrape the dirt on the inner wall of the pipeline evenly, and even when pushing too hard, it is easy to scrape the pipeline and cause the entire waste heat boiler to be unable to be used normally. Based on the deficiencies of the existing waste heat boiler pipeline cleaning, this application proposes a cleaning tool for waste heat boiler pipelines to achieve rapid and efficient cleaning of waste heat boiler pipelines. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cleaning tool for waste heat boiler pipelines to achieve rapid and efficient cleaning of waste heat boiler pipelines.

[0005] The utility model is realized through the following technical solutions:

[0006] A cleaning tool for waste heat boiler pipelines includes a moving base, a fork-type telescopic mechanism is arranged on the moving base, a lifting plate is arranged at the upper end of the fork-type telescopic mechanism, a guiding cylinder is fixed on the lifting plate, a cleaning rod penetrates through the guiding cylinder, a cleaning cone head is arranged at one end of the cleaning rod, and a driving component for driving the cleaning rod to move along the direction of the guiding cylinder is arranged on the lifting plate;

[0007] The cleaning rod is hollowly arranged and a reinforcing cylinder is arranged at the end connected to the cleaning cone head, a plurality of exhaust holes are evenly opened on the reinforcing cylinder, and the other end of the cleaning rod is connected to a compressed air source through an air pipe.

[0008] As a further setting of the above solution, the fork-type telescopic mechanism includes two fork frames connected to the upper surface of the moving base, the lifting plate is connected to the tops of the two fork frames, and a lead screw assembly for driving the two fork frames to operate synchronously is arranged on the lifting plate.

[0009] As a further setting of the above solution, the lead screw assembly includes a lead screw rotatably connected to the upper surface of the moving base, and a hand wheel is connected to the outer end of the lead screw. One side of the lower ends of the two fork frames is connected with a longitudinal rod, and a lead screw nut matching the lead screw is arranged on the longitudinal rod.

[0010] As a further setting of the above solution, the driving assembly includes two vertical rotating shafts rotatably connected to the lifting plate. Biting wheels are arranged at the upper ends of the two vertical rotating shafts, and the wheel gap between the two biting wheels is on the same straight line as the guiding cylinder. Gears meshing with each other are arranged at the lower ends of the two vertical rotating shafts. A gear box connected to the lifting plate is arranged outside the gears, and a driving motor connected to one of the vertical rotating shafts is arranged on the gear box.

[0011] As a further setting of the above solution, the exhaust holes opened on the guiding cylinder are all inclined towards the lifting plate.

[0012] As a further setting of the above solution, a cover is sleeved on the cleaning rod near the side of the reinforcing cylinder, and a dust discharge pipe is connected to the lower end of the cover.

[0013] As a further setting of the above solution, the moving base includes a bottom box. A plurality of universal wheels are arranged on the lower surface of the bottom box, and a handle is arranged at one end of the bottom box. Beneficial effects

[0014] When the waste heat boiler pipeline cleaning tooling disclosed in this patent is in use, only the cleaning rod and the cleaning cone head need to be aligned with the pipeline opening, and then the driving assembly automatically pushes the two into the pipeline. At the same time, the guiding cylinder is used to limit the moving path of the cleaning rod, so that the cleaning rod and the cleaning cone head can be automatically pushed along the central axis of the pipeline, and the inside of the pipeline is cleaned during the pushing process, solving the problems of high labor intensity and low operation efficiency when manually pushing the cleaning rod and the cleaning cone head, and avoiding the problem that when the manual pushing deviates, it is impossible to evenly scrape off the dirt on the inner wall of the pipeline, and even the pipeline is easily scratched when the force is too strong.

[0015] This patent also makes the cleaning rod hollow. During the process of pushing the cleaning rod and the cleaning cone head, the high-pressure air flow can be discharged from the exhaust holes on the reinforcing cylinder, and the inner wall of the pipeline is flushed by the high-pressure air flow, improving the cleaning effect on the inner wall of the pipeline. And the dust flushed out can be guided by the cover, avoiding the dust spraying towards the tooling and the operators along with the air flow, and ensuring the operation environment.

[0021] In order to enable those skilled in the art to better understand the solutions of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0022] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the attached Figures 1 to 4 , and will describe this application in detail in conjunction with the embodiments. Embodiment 1

[0023] Embodiment 1 discloses a waste heat boiler pipeline cleaning tooling. Referring to the attached Figures 1 - 3 , it includes a moving base 1, which is composed of a bottom box 101 and four universal wheels 102. The four universal wheels 102 are respectively arranged at the four corners of the lower surface of the bottom box 101, so that the entire moving base 1 can be moved in any direction. In addition, in order to facilitate the movement of the moving base 1, a handle 103 is welded at one end of it.

[0024] On the upper surface of the bottom box 101, there are two front and rear fork frames 2. The right sides of the lower ends of the two fork frames 2 are rotatably connected to the hinge seats 3 on the upper surface of the bottom box 101. Then, a longitudinal rod 4 is connected to the left sides of the lower ends of the two fork frames 2, and a slot track 5 matching the front and rear ends of the longitudinal rod 4 is arranged on the bottom box 101. Above the two fork frames 2, there is a lifting plate 9. A hinge seat 3 is also arranged on the left side of the lower surface of the lifting plate 9, and the left sides of the upper ends of the two fork frames 2 are connected to the hinge seat 3. A longitudinal rod 4 is also connected to the right sides of the upper ends of the two fork frames 2. Similarly, a slot track 5 matching the front and rear ends of the longitudinal rod 4 is arranged on the lower surface of the lifting plate 9.

[0025] On the upper surface of the bottom box 101, a lead screw 6 perpendicular to the longitudinal rod 4 is arranged. One end of the lead screw 6 is rotatably connected to the bearing seat on the upper surface of the bottom box 101, and the other end is connected with a hand wheel 7. Then, a lead screw nut 8 matching the lead screw 6 is arranged on the longitudinal rod 4 at the lower ends of the two fork frames 2. By rotating the hand wheel 7, the lead screw 6 rotates, and then the synchronous expansion and contraction of the two fork frames 2 can be realized by the interaction between the lead screw 6 and the lead screw nut 8, thereby realizing the up and down lifting of the lifting plate 9.

[0026] On the upper surface of the lifting plate 9, a horizontally arranged guide cylinder 10 is welded. A cleaning rod 11 is inserted through the guide cylinder 10. A cleaning cone head 12 is welded to the right end of the cleaning rod 11, and the maximum diameter of the cleaning cone head 12 is slightly smaller than the inner diameter of the pipeline of the waste heat boiler. At the same time, the total length of the cleaning rod 11 is greater than the length of the pipeline in the waste heat boiler. Therefore, the tail end of the cleaning rod 11 can be inserted to increase the total length of the cleaning rod 11.

[0027] On the upper surface of the lifting plate 9 on the left side of the guide cylinder 10, a row of idler rollers 13 is arranged to prevent the left end of the cleaning rod 11 from bending downward due to its excessive length. On the upper surface of the lifting plate 9 on the right side of the guide cylinder 10, a driving assembly 14 for driving the cleaning rod 11 to move to the right is arranged. Specifically, the driving assembly 14 includes two vertical rotating shafts 141 rotatably arranged on the lifting plate 9. At the upper ends of the two vertical rotating shafts 141, a biting wheel 142 is arranged respectively, and the wheel gap between the two biting wheels 142 is on the same straight line as the guide cylinder 10, so that the cleaning rod 11 can pass through the wheel gap between the two biting wheels 142. At the lower ends of the two vertical rotating shafts 141, a gear 143 is arranged respectively, and the two gears 143 are meshed with each other. Then, a gear box 144 connected to the lower surface of the lifting plate 9 is arranged on the periphery of the two gears 143, and a driving motor 145 connected to one of the vertical rotating shafts 141 is arranged on the gear box 144.

[0028] Finally, a control box 15 is provided on the lifting plate 9 or the moving base 1, and switches for controlling corresponding electrical components are arranged inside the control box 15. The entire cleaning tooling can be powered by a storage battery arranged inside the bottom box 101, or connected to an external circuit through a wire for power supply.

[0029] When the waste heat boiler pipeline cleaning tooling disclosed in Embodiment 1 is in use, the entire tooling is pushed until it is flush with the end of the pipeline of the waste heat boiler, and then the height is adjusted by rotating the handwheel until the cleaning rod 11 and the cleaning cone head 12 are precisely aligned with the pipeline opening. Subsequently, the drive motor 145 is started, and the synchronous reverse rotation of the two biting wheels 142 is realized through the meshing transmission of the two gears 143. Then, the two biting wheels 142 will push the cleaning rod 11 towards the direction of the pipeline central axis. During the pushing process, the cleaning cone head 12 can scrape off the dirt on the inner wall of the pipeline and push it out of the pipeline.

[0030] After the cleaning of this pipeline is completed, the drive motor 145 is started in reverse for retraction and reset, and then the entire tooling is moved and the height is adjusted until it is precisely aligned with another pipeline, and then this pipeline is cleaned until the cleaning of all pipelines is completed. Embodiment 2

[0031] Embodiment 2 discloses a waste heat boiler pipeline cleaning tooling which is an improved design based on the technical solution of Embodiment 1, and the same parts as those in Embodiment 1 will not be described again.

[0032] Refer to the appendix Figure 1 and the appendix Figure 4 In this Embodiment 2, the cleaning rod 11 is provided with a hollow interior, forming an air flow channel capable of introducing high-pressure gas inside. At the end of the connection between the cleaning rod 11 and the cleaning cone head 12, there is a reinforcing cylinder 16. The inner cavity of the reinforcing cylinder 16 is connected to the hollow inner cavity of the cleaning rod 11, and then a plurality of exhaust holes 161 inclined to the left are uniformly arranged on the outer circumferential surface of the reinforcing cylinder 16.

[0033] An air pump 17 or other compressed air sources are arranged on the upper surface of the lifting plate 9. Then, an air pipe 18 is connected to the air pump 17, and the end of the air pipe 18 is hermetically connected to the left end of the cleaning rod 11, so that the high-pressure gas generated by the air pump 17 can flow along the hollow inner cavity of the cleaning rod 11.

[0034] Finally, a cover 19 is sleeved on the cleaning rod 11 near the side of the reinforcing cylinder 16. The right side of the cover 19 is open, and an ash discharge pipe 191 is connected to its lower end.

[0035] In the process of pushing the cleaning rod 1 into the pipeline in the second embodiment, the cleaning cone head 12 scrapes off the dirt on the inner wall of the pipeline. At the same time, high-pressure air flow continuously sprays out from the exhaust holes 161 and acts on the inner wall of the pipeline, and secondary flushing is carried out by using the high-pressure air flow. The dust washed down can move towards the left end of the cleaning rod 11. At this time, the cover 19 is attached to the port of the pipeline, so that the air flow and dust are discharged downward from the dust discharge pipe 191, avoiding directly spraying towards the whole tooling and operators.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
