Description

Technical Field

[0001] This invention belongs to the field of seamless steel pipe surface treatment technology, specifically a device for cleaning the surface of seamless steel pipes and its usage method. Background Technology

[0002] Seamless steel pipe is a type of pipe made through processes such as hot rolling, cold rolling, or cold drawing. It has no welded joints and its inner and outer surfaces are smooth. For the surface treatment of seamless steel pipe, cleaning equipment is usually used to remove dirt from the surface of the seamless steel pipe.

[0003] Existing seamless steel pipe surface cleaning devices typically involve placing the seamless steel pipe in a cleaning zone and using a spray system to spray cleaning agents onto its surface. However, in actual cleaning, large-volume seamless steel pipes need to be placed in the spray cleaning zone, and the outer surface of the seamless steel pipe is covered by the sprayed cleaning agent throughout the cleaning process. It is difficult to detect the cleaning status of the seamless steel pipe in time, requiring the machine to be stopped to assess the cleaning effect. At the same time, due to the curvature of the large-volume seamless steel pipe during spraying, it is difficult to rinse the bottom of the seamless steel pipe with a single spray of cleaning agent. In practice, the angle of the seamless steel pipe needs to be adjusted periodically to complete the comprehensive cleaning of the outer surface. The actual cleaning status is difficult to judge, the cleaning process requires intermediate adjustments, each cleaning session is time-consuming, and the cleaning efficiency is low.

[0004] Furthermore, existing seamless steel pipe surface cleaning devices require lifting equipment to remove the cleaned seamless steel pipes from the cleaning area after cleaning. For large-volume seamless steel pipes, a single cleaning process requires two lifting and handling steps for loading and unloading. After handling, drying is also required. The cleaning process for large-volume seamless steel pipes involves numerous steps, with low synchronization rates between different steps. The overall cleaning operation is cumbersome, and each step is difficult, resulting in poor performance. Summary of the Invention

[0014] Preferably, a sliding groove is provided on the rear end face of the processing box, the inner surface of the sliding groove is slidably engaged with the sliding plate, and a shielding frame is fixedly connected to the top of the processing box.

[0015] A method for using a surface cleaning device for seamless steel pipes includes the following operating steps:

[0016] Step 1: Use the lifting equipment to lift the seamless steel pipe to be cleaned between the two sets of support plates, so that the two sides of the bottom surface of the seamless steel pipe are in contact with the pushing component, and the bottom surface of the seamless steel pipe is in contact with the cleaning component. Start the pushing component, so that the two sets of pushing components rotate in the same direction at the same time, pushing the seamless steel pipe to rotate between the two sets of inclined support plates.

[0017] Step 2: Start the power unit, which drives the cleaning unit to rotate along the bottom surface of the seamless steel pipe. At the same time, the power unit generates axial air in the air supply unit. The axial air is introduced into the support plate, which causes gas to be ejected from the jet holes on the front of the support plate. The ejected gas is blown along both sides of the outer surface of the seamless steel pipe toward the rotating seamless steel pipe.

[0018] Step 3: Start the external liquid pump connected to the connecting pipe, so that the liquid pump draws the cleaning liquid and pumps it into the connecting frame and inputs it into the inner hole of the rotating shaft, so that the cleaning liquid is sprayed out from the spray hole on the front of the support plate, and the cleaning liquid sprayed from both sides is sprayed out simultaneously along the diagonal downward of the seamless steel pipe, and concentrated towards the direct bottom of the seamless steel pipe. As the cleaning component rotates and rubs against the bottom surface of the seamless steel pipe, the bottom surface of the seamless steel pipe is cleaned and decontaminated. As the seamless steel pipe rotates, the entire outer surface of the seamless steel pipe is cleaned and decontaminated.

[0019] Step 4: After observing that the surface of the seamless steel pipe has been cleaned, stop pumping in the cleaning solution, maintain the rotation of the seamless steel pipe and keep the power component rotating, so that while the seamless steel pipe continues to rotate, the air jet holes on both sides of the seamless steel pipe spray out gas to complete the comprehensive blowing and drying of the outer surface of the seamless steel pipe.

[0020] Step 5: After cleaning and drying, activate a set of electric push rods in the flipping control assembly. These electric push rods push the toothed plate upward. As the toothed plate moves vertically upward, it pushes the meshing gear number one to rotate. This causes the gear number one to drive the fixedly sleeved rotating shaft to rotate. The rotating shaft then drives a set of support plates to rotate downward around the rotating shaft. As the support plates flip downward to their outer ends and tilt downward, the processed seamless steel pipe rolls down along the tilted support plates, completing the rapid discharge.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. This invention utilizes a flipping control component to tilt two sets of support plates at the top of the processing box, accommodating the placement of seamless steel pipes. Combined with a pushing component added to the front of the support plates, the seamless steel pipe located between the two sets of support plates rotates synchronously with the two pushing components. Simultaneously, with the flexible baffles on both sides, and using the top support plate, seamless steel pipe, and spray holes located near the bottom of the front of the support plate, the cleaning fluid is confined to the lower space during actual spray cleaning. The top of the seamless steel pipe remains exposed to the environment during cleaning. Combined with the bottom cleaning component and the rotating seamless steel pipe, the cleaning process... Finally, the seamless steel pipe is partially cleaned in the bottom space, while the rotation effect completes the overall cleaning. This reduces the need for active adjustment of the cleaning angle during the actual cleaning process. Operators can clearly monitor the cleaning environment from one side. For cleaning large-volume seamless steel pipes, this method greatly improves the convenience and efficiency of the cleaning operation. Furthermore, it allows for easy observation of the actual cleaning progress for seamless steel pipes with varying levels of contamination, enabling timely control of the cleaning process and avoiding incomplete cleaning within a fixed time or excessive cleaning time that wastes resources. The results are excellent.

[0023] 2. This invention utilizes the positional distribution of air jet holes and liquid spray holes, in conjunction with the positional distribution of the seamless steel pipe and the support plates on both sides. This allows the air jet holes to initiate the blowing of the seamless steel pipe from above, while the liquid spray holes rinse and remove contaminants from the bottom. By isolating the upper and lower rinsing liquids from the upper space, after the contamination removal is completed, the continuous rotation of the power component and the continuous rotation of the seamless steel pipe seamlessly switch from contamination cleaning to surface air drying. Furthermore, the rotating seamless steel pipe enables rapid and comprehensive drying after contamination cleaning, further shortening intermediate operation time and avoiding the need for additional drying steps after handling the seamless steel pipe. This comprehensively improves the contamination treatment efficiency when processing seamless steel pipes in batches, resulting in excellent performance.

[0024] 3. This invention utilizes a flipping control component. After the seamless steel pipe has been cleaned and air-dried, a set of electric push rods are activated, pushing the toothed plate upwards. This causes the meshing gear number one to rotate, which in turn causes the rotating shaft to drive a set of support plates to rotate downwards. The outer end of the support plate rotates from the top to the bottom. Combined with the inclined support plate on the other side and the rotating push component, along with the weight of the seamless steel pipe and the rotational push component at the bottom, the seamless steel pipe automatically rolls away. For large-volume seamless steel pipes, there is no need to restart the lifting equipment for lifting and unloading. The actual unloading is convenient and effective, shortens the operation process, reduces the difficulty of unloading, and has good performance. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figures 1 to 11As shown, this embodiment of the invention provides a surface cleaning device for seamless steel pipes and its usage method, including a treatment box 1. A notch 2 is provided on the side of the treatment box 1. A movable baffle 3 is movably fitted into the inner wall of the treatment box 1. A support plate 4 is provided inside the treatment box 1. A rotating shaft 5 is fixedly fitted inside the support plate 4 and rotatably fitted inside the treatment box 1. One end of the rotating shaft 5 has an inner hole 6. A spray hole 7 and a jet hole 8 are respectively provided on the front of the support plate 4. A connecting groove 9 and a connecting hole 10 are respectively provided inside the support plate 4. A rotatable push assembly 20 is fitted, and a first gear 13 is fixedly fitted on the outer surface of the rotating shaft 5. A flip control assembly 14 is provided at the rear end of the treatment box 1, and the flip control assembly 14 meshes with the first gear 13. A cleaning assembly 15 is rotatably installed in the treatment box 1. A power assembly 16 is provided at the front end of the treatment box 1. An air supply assembly 17 is provided at one end of the power assembly 16 and is connected to the support plate 4. A connecting frame 18 is fixedly connected to the front end of the treatment box 1 and is connected to one end of the rotating shaft 5. A seamless steel pipe 25 is provided on the top of the support plate 4.

[0039] First embodiment: In use, the hoisting equipment is used to lift the seamless steel pipe 25 to be cleaned between the two sets of support plates 4, so that both sides of the bottom surface of the seamless steel pipe 25 contact the pushing assembly 20, specifically so that the rotating roller 201 in the pushing assembly 20 contacts the surface of the seamless steel pipe 25, and at the same time, the bottom surface of the seamless steel pipe 25 contacts the cleaning assembly 15, specifically so that the cleaning roller 151 in the cleaning assembly 15 contacts the bottom of the seamless steel pipe 25. The pushing assembly 20 is activated, so that the second motor 204 in the two sets of pushing assemblies 20 drives the sleeve shaft 202 to rotate, thereby causing the rotating roller 201 located in the adapter groove 11 to rotate. As the two sets of rotating rollers 201 rotate simultaneously in the same direction, the seamless steel pipe 25 is pushed between the two sets of support plates 4. The inclined support plate 4 rotates, activating the power assembly 16. This causes the first motor 162 in the power assembly 16 to drive the third shaft 163 to rotate, which in turn rotates the third gear 164. This, in turn, drives the second gear 153 in the cleaning assembly 15 to rotate, causing the second shaft 152 in the cleaning assembly 15 to drive the cleaning roller 151. The cleaning roller 151, a rotating part with bristles on its outer surface, rotates along the bottom surface of the seamless steel pipe 25. Simultaneously, the rotation of the third shaft 163 in the power assembly 16 drives the fan blades 172 in the air supply assembly 17 to rotate, thus drawing ambient air into the air supply sleeve 171 through the air inlet 174, generating axial airflow. This axial airflow is then introduced into the support plate 4 through the air pipe 173. In the connecting hole 10, the flowing air entering the connecting hole 10 is ejected from the jet hole 8 on the front of the support plate 4, and the ejected gas is blown along both sides of the outer surface of the seamless steel pipe 25 toward the rotating seamless steel pipe 25. The external liquid pump connected to the connecting pipe 19 is started, so that the liquid pump draws the cleaning liquid and pumps it into the connecting frame 18. The cleaning liquid entering the connecting frame 18 is fed into the inner hole 6 of the connected rotating shaft 5, so that the cleaning liquid passes through the inner hole 6, the connecting groove 9 and enters the spray hole 7. The cleaning liquid is ejected from the spray hole 7 on the front of the support plate 4, and the inclined arrangement of the spray hole 7 makes the cleaning liquid sprayed from both sides spray out simultaneously along the oblique downward of the seamless steel pipe 25, and concentrated towards the front of the seamless steel pipe 25. At the contact point of the lower cleaning roller 151, as the cleaning component 15 rotates and rubs against the bottom surface of the seamless steel pipe 25, the bottom surface of the seamless steel pipe 25 is cleaned and decontaminated. As the seamless steel pipe 25 rotates, the entire outer surface of the seamless steel pipe 25 is cleaned and decontaminated. The sprayed cleaning fluid is confined to the two sets of movable baffles 3, the support plate 4, and below the seamless steel pipe 25. Observing the surface of the seamless steel pipe 25 from the outside of the device, after the decontamination and cleaning are completed, the pumping of the cleaning fluid is stopped. The rotation of the seamless steel pipe 25 and the rotation of the power component 16 are maintained, so that while the seamless steel pipe 25 continues to rotate, the jet holes 8 on both sides of the seamless steel pipe 25 continue to spray gas, completing the comprehensive blowing and drying of the outer surface of the seamless steel pipe 25.

[0040] First, by using the flip control component 14, the two sets of support plates 4 are tilted and arranged on the top of the processing box 1, adapting to the placement of the seamless steel pipe 25. With the push component 20 added to the front of the support plate 4, the seamless steel pipe located between the two sets of support plates 4 rotates synchronously under the rotation of the two push components 20. Simultaneously, with the flexible connecting movable baffles 3 on both sides, the top support plate 4, the seamless steel pipe 25, and the spray holes 7 on the front of the support plate 4 near the bottom, during actual spray cleaning, the cleaning fluid is confined to the lower space. The top of the seamless steel pipe 25 remains exposed to the environment during cleaning. This, combined with the bottom cleaning component 15 and the rotating... The seamless steel pipe 25 is always cleaned locally in the bottom space, while the rotation effect completes the overall cleaning. In actual cleaning, the active adjustment of the cleaning angle of the seamless steel pipe 25 is reduced. At the same time, the operator can clearly monitor the cleaning environment from one side. For cleaning large-volume seamless steel pipes 25, this greatly improves the convenience and efficiency of the cleaning operation. On the other hand, it allows for easy observation of the actual cleaning situation for seamless steel pipes with different levels of contamination, enabling timely control of the cleaning process and avoiding incomplete cleaning within a fixed time or waste of resources due to excessive cleaning time. The effect is good.

[0041] Furthermore, by utilizing the positional distribution of the jet nozzles 8 and liquid spray nozzles 7, in conjunction with the positional distribution of the seamless steel pipe 25 and the two side support plates 4, the jet nozzles 8 initiate the blowing of the seamless steel pipe 25 from above, while the liquid spray nozzles 7 rinse and remove contaminants from the localized cleaning areas from below. Utilizing the isolation between the upper and lower rinsing liquids and the upper space, after the contamination removal is completed, in conjunction with the continuous rotation of the power component 16 and the continuous rotation of the seamless steel pipe 25, the process seamlessly switches from contamination cleaning to surface air drying. Moreover, the rotating seamless steel pipe 25 enables rapid and comprehensive drying after contamination cleaning, further shortening the intermediate operation time, avoiding the need for additional drying steps after handling the seamless steel pipe, and comprehensively improving the contamination treatment efficiency when processing seamless steel pipes 25 in batches, resulting in good performance.

[0042] Second embodiment: After cleaning and drying are completed, a set of electric push rods 142 in the flipping control assembly 14 are activated, so that the electric push rods 142 push the toothed plate 144 upward. As the toothed plate 144 moves vertically upward, it pushes the meshing first gear 13 to rotate, thereby causing the first gear 13 to drive the fixedly sleeved rotating shaft 5 to rotate. This causes the rotating shaft 5 to drive a set of support plates 4 to rotate downward around the rotating shaft 5. As the support plates 4 flip downward to the outer end and tilt downward, the processed seamless steel pipe 25 rolls down along the tilted downward support plate 4, completing the rapid discharge.

[0043] First, by using the flipping control component 14, after the seamless steel pipe 25 has been cleaned and dried by air, a set of electric push rods 142 are activated to push the toothed plate 144 upward, thereby rotating the meshing gear 13. This causes the rotating shaft 5 to drive a set of support plates 4 to rotate downward, so that the outer end of the support plate 4 rotates from the top to the bottom. With the other side of the inclined support plate 4 and the rotating push component 20, combined with the weight of the seamless steel pipe 25 and the rotational push of the bottom contact push component 20, the seamless steel pipe 25 automatically rolls away. For large-volume seamless steel pipes 25, there is no need to start the lifting equipment again for lifting and unloading. The actual unloading is convenient and effective, shortens the operation process, reduces the difficulty of unloading, and has a good effect.

[0044] like Figure 1 , Figure 2 , Figure 4 and Figure 11 As shown, the processing box 1 has an internal movable groove 22, which is connected to the notch 2. The inner surface of the movable groove 22 is movably connected to the movable baffle 3. A spring 24 is fixedly connected to the bottom of the inner surface of the movable groove 22, and the upper end of the spring 24 is fixedly connected to the movable baffle 3.

[0045] During use, the movable baffle 3, which is connected to the spring 24 by the movable sleeve, adapts to the rotation and swing of the support plate 4, and always maintains contact with the back of the support plate 4 to form a seal and prevent the cleaning fluid from splashing out.

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, there are two support plates 4, which are symmetrically distributed on the top of the processing box 1. The seamless steel pipe 25 is located between the two support plates 4. An inclined groove 12 is opened on the lower front side of the support plate 4. The connecting hole 10 is connected to the jet hole 8. The two ends of the connecting groove 9 are connected to the inner hole 6 and the liquid spraying hole 7, respectively. The liquid spraying hole 7 is located below the outer surface of the seamless steel pipe 25, and the jet hole 8 is located diagonally above the outer surface of the seamless steel pipe 25. The inner hole 6 is connected to the connecting frame 18, and the top of the connecting frame 18 is fixedly connected to the connecting pipe 19.

[0047] During use, a closed cleaning zone is formed by two sets of support plates 4, seamless steel pipe 25, and movable baffles 3 on both sides. With the air jet holes 8 and liquid spray holes 7 arranged above and below, the top of the seamless steel pipe 25 is started to be blown and the bottom is rinsed with cleaning fluid. The connecting holes 10 are used to connect multiple sets of air jet holes 8, and the connecting grooves 9 are used to connect multiple sets of liquid spray holes 7. With the help of the inclined grooves 12, the direction of the liquid spray holes 7 is determined and sprayed towards the cleaning position.

[0048] like Figure 2 , Figure 5 and Figure 10 As shown, the flipping control assembly 14 includes a base plate 141, an electric push rod 142, a connecting block 143, a toothed plate 144, and a sliding plate 145. The base plate 141 is fixedly connected to the rear end face of the processing box 1. There are two electric push rods 142, both of which are fixedly installed on the top surface of the base plate 141. The connecting block 143 is fixedly connected to the top end of the electric push rod 142. The number of toothed plates 144 is the same as that of the electric push rods 142. The two toothed plates 144 mesh with two first gears 13 respectively. The toothed plates 144 are fixedly connected to the connecting block 143. The sliding plate 145 is fixedly connected to the back side of the toothed plates 144.

[0049] During use, the flip control component 14 is used to flip the two sets of support plates 4, and when needed, a single set of support plates 4 is controlled to rotate and open, and the seamless steel pipe 25 after processing is guided to slide out by itself in conjunction with the downward tilting support plate 4.

[0050] like Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, the cleaning assembly 15 includes a cleaning roller 151, a second shaft 152, and a second gear 153. The second shaft 152 is rotatably sleeved inside the processing box 1. The cleaning roller 151 is fixedly sleeved on the outer surface of the second shaft 152. The cleaning roller 151 is located directly below the seamless steel pipe 25. The second gear 153 is fixedly sleeved on the outer surface of the second shaft 152. The power assembly 16 includes a motor base 161, a first motor 162, a third shaft 163, and a third gear 164. The motor base 161 is fixedly connected to the front end face of the processing box 1. The first motor 162 is fixedly installed inside the motor base 161. The third shaft 163 is fixedly connected to the output shaft of the first motor 162. The third gear 164 is fixedly sleeved on the outer surface of the third shaft 163 and meshes with the second gear 153.

[0051] During use, the bottom of the seamless steel pipe 25 is rotated and cleaned by the cleaning component 15, and the cleaning liquid sprayed from both sides is used to remove dirt and clean it. The power component 16 provides rotational power and uses gear meshing to achieve transmission, so that the cleaning component 15 rotates.

[0052] like Figure 1 , Figure 5 , Figure 6 and Figure 9As shown, the air supply assembly 17 includes an air supply sleeve 171, a fan blade 172, an air pipe 173, and an air inlet 174. The air supply sleeve 171 is fixedly connected to the front end face of the processing box 1. The front end of the air supply sleeve 171 is rotatably connected to the No. 3 shaft 163. The fan blade 172 is located inside the air supply sleeve 171 and is fixedly sleeved on the outer surface of the No. 3 shaft 163. The air pipe 173 is fixedly connected between the air supply sleeve 171 and the support plate 4. One end of the air pipe 173 is connected to the connecting hole 10. The air inlet 174 is opened on the end face of the air supply sleeve 171.

[0053] During use, the power unit 16 provides rotational power to rotate the fan blades 172, and the resulting axial airflow is introduced into the support plate 4. This, along with the jet nozzles 8, completes the gas purging, which on the one hand helps to improve the surface cleaning efficiency, and on the other hand, performs air drying when the cleaning fluid supply stops.

[0054] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the pushing assembly 20 includes a rotating roller 201, a sleeve shaft 202, a motor frame 203, and a second motor 204. The support plate 4 has an adapter groove 11 on its front side. The sleeve shaft 202 is rotatably sleeved inside the support plate 4.

The motor frame 203 is fixedly connected to the rear end face of the support plate 4. The second motor 204 is fixedly installed inside the motor frame 203. The output shaft of the second motor 204 is fixedly connected to the sleeve shaft 202.

[0055] The processing box 1 has a groove 23 on its rear end face, the inner surface of the groove 23 is slidably connected to the slide plate 145, and a shielding frame 21 is fixedly connected to the top of the processing box 1.

[0056] During use, the rotation of the pushing component 20 drives the rotation of the seamless steel pipe 25 placed in front of the support plate 4, thereby achieving comprehensive cleaning of the outer surface at the bottom through continuous rotation, while completing wind drying at the upper angle, improving the efficiency of the outer surface treatment of the seamless steel pipe 25, and assisting in pushing the seamless steel pipe 25 to roll and slide during unloading, while the shielding frame 21 further reduces the splashing of cleaning liquid.

[0057] A method for using a surface cleaning device for seamless steel pipes includes the following operating steps:

[0058] Step 1: Use the hoisting equipment to lift the seamless steel pipe 25 to be cleaned between the two sets of support plates 4, so that the two sides of the bottom surface of the seamless steel pipe 25 are in contact with the pushing component 20, and the bottom surface of the seamless steel pipe 25 is in contact with the cleaning component 15. Start the pushing component 20, so that the two sets of pushing components 20 rotate in the same direction at the same time, pushing the seamless steel pipe 25 to rotate in the two sets of inclined support plates 4;

[0059] Step 2: Start the power assembly 16, which drives the cleaning assembly 15 to rotate along the bottom surface of the seamless steel pipe 25. At the same time, the power assembly 16 generates axial air in the air supply assembly 17. The axial air is introduced into the support plate 4, which causes gas to be ejected from the jet hole 8 on the front of the support plate 4. The ejected gas is blown along both sides of the outer surface of the seamless steel pipe 25 towards the rotating seamless steel pipe 25.

[0060] Step 3: Start the external liquid pump connected to the connecting pipe 19, so that the liquid pump draws the cleaning liquid and pumps it into the connecting frame 18, and inputs it into the inner hole 6 of the rotating shaft 5, so that the cleaning liquid is sprayed out from the spray hole 7 on the front of the support plate 4, and the cleaning liquid sprayed from both sides is sprayed out simultaneously along the diagonal downward of the seamless steel pipe 25, and concentrated towards the direct downward of the seamless steel pipe 25. As the cleaning component 15 rotates and rubs against the bottom surface of the seamless steel pipe 25, the bottom surface of the seamless steel pipe 25 is cleaned and decontaminated. As the seamless steel pipe 25 rotates, the outer surface of the seamless steel pipe 25 is completely cleaned and decontaminated.

[0061] Step 4: After observing that the surface of the seamless steel pipe 25 has been cleaned, stop pumping in the cleaning fluid, maintain the rotation of the seamless steel pipe 25 and keep the power component 16 rotating, so that while the seamless steel pipe 25 continues to rotate, the air jet holes 8 on both sides of the seamless steel pipe 25 spray out gas to complete the comprehensive blowing and drying of the outer surface of the seamless steel pipe 25.

[0062] Step 5: After cleaning and drying, activate a set of electric push rods 142 in the flipping control assembly 14. The electric push rods 142 push the toothed plate 144 upward. As the toothed plate 144 moves vertically upward, it pushes the meshing first gear 13 to rotate. This causes the first gear 13 to drive the fixedly sleeved rotating shaft 5 to rotate. The rotating shaft 5 then drives a set of support plates 4 to rotate downward around the rotating shaft 5. As the support plates 4 flip downward to the outer end and tilt downward, the processed seamless steel pipe 25 rolls down along the tilted support plate 4, completing the rapid discharge.
