Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to a large-diameter steel pipe soot blowing and guiding device. Background Technology

[0002] Both the blowing of iron oxide scale on the inner surface of hot-rolled steel pipes and the blowing of iron oxide scale on the inner surface of steel pipes after rotary expansion are to ensure the quality of steel pipes. The method used is to integrate the soot blowing component on the outside of the steel pipe conduction component.

[0003] Existing soot blowing assemblies are mostly composed of nozzles, pipes, air pumps, and support frames. The nozzles used on site are either straight or flared, and the airflow jetting method depends entirely on the standard nozzle configuration. This results in the existing airflow being mostly in a straight column shape, with a jetting blind zone within at least 2 meters of the pipe section, affecting the cleaning effect on iron oxide scale. Therefore, there is an urgent need to propose a corresponding large-diameter steel pipe soot blowing and guiding device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a large-diameter steel pipe soot blowing and guiding device in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A large-diameter steel pipe soot blowing and guiding device includes a base plate and a guiding assembly. The top of the base plate is integrated with a support plate and a connecting assembly for maintaining the position of the support plate. The guiding assembly includes a cyclone separator and a guiding pipe. The cyclone separator is fixedly connected to the support plate and is connected to a nozzle. An air pump is fixedly connected to the top of the base plate. The output end of the air pump is connected to the guiding pipe, and the input end of the air pump is fixedly connected to a connecting pipe.

[0007] Preferably, bracket one and bracket two are fixedly connected to the top of the base plate, a driving component is fixedly connected to the top of bracket one, a transmission rod is fixedly connected to the output end of the driving component, a threaded sleeve that is fixedly connected to the outer wall of the transmission rod is screwed onto the outer wall of the support plate, and the output end of the air pump is connected to the guide pipe through a corrugated pipe.

[0008] Preferably, a smooth rod is fixedly connected between the second bracket and the top of the base plate, and a sliding sleeve that is fixedly connected to the support plate is slidably connected to the outer wall of the smooth rod.

[0009] Preferably, both the threaded sleeve and the sliding sleeve are fixedly connected to the support plate by screws.

[0010] Preferably, the rear end face of the support plate is fixedly connected to a connecting frame by screws, and the inner wall of the connecting frame is fixedly connected to the outer wall of the guide tube.

[0011] Preferably, the bottom plate has a vertically penetrating strip groove.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. In this application, the guide pipe is connected to an external nitrogen source. After being diffused, the steel pipe is transported to the horizontal conveyor chain at the leveling front end and stays for 1.5-3 seconds. The pneumatic valve on the nitrogen source is opened, and the nitrogen is conducted through the guide pipe, then through the hydrocyclone, and finally out through the nozzle. Through the spiral guide blades inside the hydrocyclone, the nitrogen is blown out in a spiral shape. The spiral airflow formed by the guide assembly removes the iron oxide scale and salt residue on the inner surface of the steel pipe, while reducing the coverage blind zone of the nitrogen and improving the cleaning effect on the iron oxide scale.

[0014] 2. In this application, the drive component drives the transmission rod to rotate. The transmission rod provides traction force to the screw sleeve and the support plate through its engagement with the screw sleeve. The cooperation between the sliding sleeve and the smooth rod can limit the axial displacement of the support plate, so that the support plate, the nozzle and the flow guiding assembly can be displaced along the direction of the support plate. The bellows expands and contracts synchronously. This does not affect the conduction of nitrogen gas, while the height of the nozzle can be easily adjusted according to the usage requirements, thereby improving the ease of use of the large-diameter steel pipe soot blowing and flow guiding device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figure 1-4 As shown, the present invention provides a large-diameter steel pipe soot blowing and guiding device, including a base plate 4 and a guiding component 3. The top of the base plate 4 is integrated with a support plate 1 and a connecting component for maintaining the position of the support plate 1. The guiding component 3 includes a cyclone separator 301 and a guiding pipe 302. The cyclone separator 301 is fixedly connected to the support plate 1 and is connected to a nozzle 2. The top of the base plate 4 is fixedly connected to an air pump 12. The output end of the air pump 12 is connected to the guiding pipe 302, and the input end of the air pump 12 is fixedly connected to a connecting pipe 13.

[0022] Connecting pipe 13 is connected to an external nitrogen source. After being diffused, the steel pipe is transported to the horizontal moving chain at the leveling front end and stays for 1.5-3 seconds. The pneumatic valve on the nitrogen source is opened, and the nitrogen is conducted through the guide pipe 302, then through the hydrocyclone 301, and finally out through the nozzle 2. Through the spiral guide vanes inside the hydrocyclone 301, the nitrogen is blown out in a spiral shape. The spiral airflow formed by the guide assembly 3 removes the iron oxide scale and salt residue on the inner surface of the steel pipe, while reducing the coverage blind zone of the nitrogen and improving the cleaning effect on the iron oxide scale.

[0023] Specifically, such as Figure 2 and Figure 4 As shown, bracket 1 5 and bracket 2 6 are fixedly connected to the top of the base plate 4. A driving component 7 is fixedly connected to the top of bracket 1 5. A transmission rod 9 is fixedly connected to the output end of the driving component 7. A threaded sleeve 8, which is fixedly connected to the outer wall of the transmission rod 9, is screwed onto the outer wall of the support plate 1. The output end of the air pump 12 is connected to the guide pipe 302 through a corrugated pipe 15. A smooth rod 11 is fixedly connected between bracket 2 6 and the top of the base plate 4. A sliding sleeve 10, which is fixedly connected to the support plate 1, is slidably connected to the outer wall of the smooth rod 11. The driving component 7 drives the transmission rod 9 to rotate. The transmission rod 9 provides traction force to the threaded sleeve 8 and the support plate 1 through the screwing with the threaded sleeve 8. The cooperation between the sliding sleeve 10 and the smooth rod 11 can limit the axial displacement of the support plate 1, so that the support plate 1, the nozzle 2 and the guide component 3 can be displaced along the direction of the support plate 1. The corrugated pipe 15 expands and contracts synchronously. This does not affect the conduction of nitrogen, while the height of the nozzle 2 can be easily adjusted according to the usage requirements, thereby improving the convenience of using the large-diameter steel pipe soot blowing guide device.

[0024] Specifically, such as Figure 2 and Figure 3As shown, both the screw sleeve 8 and the sliding sleeve 10 are fixedly connected to the support plate 1 by screws, thereby ensuring the ease of disassembly and assembly of the support plate 1. The rear end face of the support plate 1 is fixedly connected to the connecting bracket 14 by screws. The inner wall of the connecting bracket 14 is fixedly connected to the outer wall of the guide pipe 302, thereby ensuring the stability of the linkage between the guide pipe 302 and the support plate 1. The bottom plate 4 has a vertical through-cut strip groove, thereby facilitating the connection between the bottom plate 4 and the external support components.

[0025] Working principle: Connecting pipe 13 connects to an external nitrogen source. After being diffused, the steel pipe is transported to the horizontal conveyor chain at the leveling front end and stays for 1.5-3 seconds. The pneumatic valve on the nitrogen source opens, and nitrogen is conducted through guide pipe 302, then through hydrocyclone 301, and finally out through nozzle 2. The spiral guide vanes inside hydrocyclone 301 cause the nitrogen to be blown out in a spiral shape. The spiral airflow formed by the guide assembly 3 removes iron oxide scale and salt deposits from the inner surface of the steel pipe, while reducing the nitrogen coverage blind zone and improving the cleaning of iron oxide scale. The effect is that the drive component 7 drives the transmission rod 9 to rotate, and the transmission rod 9 provides traction force to the screw sleeve 8 and the support plate 1 through the screwing with the screw sleeve 8. The cooperation between the sliding sleeve 10 and the smooth rod 11 can limit the axial displacement of the support plate 1, so that the support plate 1, the nozzle 2 and the flow guiding component 3 can be displaced along the direction of the extension of the support plate 1. The bellows 15 expands and contracts synchronously, so as not to affect the conduction of nitrogen, while the height of the nozzle 2 can be easily adjusted according to the usage requirements, thereby improving the convenience of using the large-diameter steel pipe soot blowing and flow guiding device.
