[0015] The steel pipe degreasing and cleaning device provided in the embodiment of the present application has a high-concentration grease cleaning liquid flowing inside the cleaning liquid chamber, and clean water flowing inside the clean water chamber. When the water passing cylinder moves toward the steel pipe, the high-concentration cleaning liquid flows out.

[0019] In the steel pipe degreasing and cleaning device provided in the embodiment of the present application, when the water cylinder moves toward the steel pipe, when the outer wall of the friction plate is squeezed against the inner wall of the steel pipe, the sliding ring is retained for a period of time under the action of the friction force, so that the baffle is separated from the cleaning liquid chamber, providing power for the sliding of the baffle.

[0020] In a possible implementation of the present application, the flushing component also includes a mixing assembly, the mixing assembly includes a vortex passage arranged on the outer wall of the fixed ring, and the vortex passage is rotatably fitted with the inner wall of the spray sleeve on one side away from the fixed ring, and the mixing assembly also includes a fixed block arranged on the outer wall of the fixed ring, and the fixed block is rotatably fitted with the inner wall of the spray sleeve on one side away from the fixed ring.

[0021] In the steel pipe degreasing and cleaning device provided in the embodiment of the present application, the cleaning liquid and clean water can be fully mixed inside the vortex passage to obtain a mixture with suitable concentration and uniformity.

[0023] The steel pipe degreasing and cleaning device provided in the embodiment of the present application has an adjusting component set up, so that when the water flow inside the spray sleeve becomes smaller, the openings of some second water holes adaptively become smaller, so that the sprayed water flow can be more concentrated and stable; when the water flow inside the spray sleeve becomes larger, the openings of some second water holes adaptively become larger, which can diffuse the water flow and make the liquid cover a wider range.

[0024] Another aspect of the present application provides a method for using a steel pipe degreasing and cleaning device, the purpose of which is to effectively clean the grease attached to the inner wall of the steel pipe in a short time by combining flushing and brushing, thereby avoiding the phenomenon that residues remain on the inner wall of the steel pipe after cleaning.

[0025] The technical solution of the present invention is: a method for using a steel pipe degreasing and cleaning device, comprising the following steps:

[0026] S1: The staff introduces clean water into the first connecting pipe and introduces high-concentration grease cleaning liquid into the second connecting pipe. Then, the clean water first flows out from the clean water chamber, flows along the inside of the vortex passage, flows through the cleaning liquid chamber, passes through the water cylinder and sprays out from the inside of the multiple first water holes. The high-concentration grease cleaning liquid is blocked by the baffle and does not flow out.

[0027] S2: Control the output shaft of the driving motor to rotate, drive the steel pipe to rotate and drive the movable block and the water cylinder to move towards the steel pipe. In this process, the baffle is separated from the cleaning liquid chamber, and the high-concentration cleaning liquid flows out from the inside of the cleaning liquid chamber. The cleaning liquid and clean water are fully mixed inside the vortex passage. Finally, the mixture is sprayed from the inside of the spray sleeve to wash the inner wall of the steel pipe. Then, the bristles on the outer wall of the water cylinder can brush the grease residue on the inner wall of the steel pipe.

[0028] S3: When the bristles have completely passed through the steel pipe, the friction plate has been separated from the inner wall of the steel pipe and reset under the action of the arc spring sheet, and under the action of the reciprocating screw, the water cylinder is driven to move away from the steel pipe, and then the friction plate contacts the inner wall of the steel pipe again. However, at this time, the sliding ring and the fixed ring are against each other, and the sliding ring moves synchronously with the water cylinder away from the steel pipe. In this process, the baffle always blocks the outlet of the cleaning liquid chamber, so that when the water cylinder moves away from the steel pipe, the cleaning liquid does not flow out, and the clean water flows out from the inside of the clean water chamber, and is sprayed from the inside of the liquid spray sleeve through the vortex passage to flush the cleaning liquid remaining on the inner wall of the steel pipe, ensuring that the cleaning liquid on the inner wall of the steel pipe is completely removed;

[0029] S4: In the process of cleaning grease on the inner wall of the steel pipe, when the water flow inside the spray sleeve becomes smaller, due to the elastic force of the strip spring piece itself, the strip spring piece can increase the blocking area of ​​part of the second water holes, thereby making the overall water outlet of the spray sleeve smaller; when the water flow inside the spray sleeve becomes larger, the water flow pushes the strip spring piece, thereby reducing the blocking area of ​​part of the second water holes by the strip spring piece, thereby increasing the overall water outlet of the spray sleeve.

[0030] The method for using the steel pipe degreasing and cleaning device provided in the embodiment of the present application is as follows: when the water-passing cylinder moves toward the direction approaching the steel pipe, clean water first flows out from the inside of the clean water chamber, flows along the inside of the vortex passage, and flows through the cleaning liquid chamber; the baffle opens, and the cleaning liquid immediately flows out from the cleaning liquid chamber; the cleaning liquid merges with the clean water and continues to rotate inside the vortex passage, so that the cleaning liquid and the clean water can be fully mixed inside the vortex passage to obtain a mixture with appropriate concentration and uniformity; the active ingredients in the high-concentration cleaning liquid are completely dissolved and dispersed in the clean water, and the cleaning liquid can be fully utilized; when the water-passing cylinder moves away from the steel pipe, the cleaning liquid does not flow out, and the clean water flows out from the inside of the clean water chamber and is sprayed from the inside of the liquid spray sleeve to flush the cleaning liquid remaining on the inner wall of the steel pipe, thereby ensuring that the cleaning liquid on the inner wall of the steel pipe is completely removed, and avoiding the adverse effects of residues on the steel pipe and subsequent fluids.

[0031] In a possible implementation of the present application, in S2, the output shaft of the driving motor is controlled to rotate, which can drive the active roller to rotate, and then drive the steel pipe and the driven roller to rotate. At the same time, the rotation of the active roller drives the reciprocating screw to rotate, and the reciprocating screw drives the movable block and the water cylinder to move toward the steel pipe. When the outer wall of the friction plate is squeezed with the inner wall of the steel pipe, the sliding ring is retained under the action of friction, the baffle is separated from the cleaning liquid chamber, and the high-concentration cleaning liquid flows out from the inside of the cleaning liquid chamber, and then the cleaning liquid merges with the clean water and continues to flow inside the vortex passage. Continue to rotate, so that the cleaning liquid and clean water can be fully mixed in the vortex passage to obtain a mixture of suitable concentration and uniformity, and finally the grease cleaning liquid of suitable concentration is sprayed out from the second water hole, driving the liquid spray sleeve to rotate, flushing the inner wall of the steel pipe, and dissolving the grease attached to the inner wall of the steel pipe. When the sliding ring slides to the limit position on the outer wall of the water cylinder, under the push of the water cylinder, the sliding ring drives the baffle to move synchronously with the water cylinder toward the direction close to the steel pipe, and then the bristles on the outer wall of the water cylinder can brush the grease residue on the inner wall of the steel pipe.

[0032] The method of using the steel pipe degreasing and cleaning device provided in the embodiment of the present application is that when the water cylinder moves toward the direction close to the steel pipe, the mixture between the high-concentration cleaning liquid and clean water and the bristles can comprehensively clean the inner wall of the steel pipe, effectively improving the cleaning effect of the inner wall of the steel pipe.

[0033] Beneficial effects of the present invention:

[0034] By controlling the output shaft of the driving motor to rotate, the steel pipe can be driven to rotate. At the same time, the water cylinder moves towards the steel pipe, and the grease cleaning liquid is sprayed out from the multiple first water holes to flush the grease on the inner wall of the steel pipe. Then, the bristles on the outer wall of the water cylinder can comprehensively brush the grease residue on the inner wall of the steel pipe. By combining flushing and brushing, the grease attached to the inner wall of the steel pipe can be effectively cleaned in a short time, avoiding the phenomenon that residues remain on the inner wall of the steel pipe after cleaning, and effectively improving the cleaning effect of the inner wall of the steel pipe.

[0035] When the water cylinder moves away from the steel pipe, the baffle always blocks the outlet of the cleaning liquid chamber, and the cleaning liquid does not flow out. Clean water flows out from the inside of the clean water chamber and is sprayed from the inside of the spray sleeve to flush the cleaning liquid remaining on the inner wall of the steel pipe, ensuring that the cleaning liquid on the inner wall of the steel pipe is completely removed, avoiding the cleaning liquid residue from having adverse effects on the steel pipe and subsequent fluids.

[0036] When the water cylinder moves toward the steel pipe, clean water first flows out from the clean water chamber and flows along the vortex passage. The baffle opens, and the cleaning liquid flows out from the cleaning liquid chamber. The cleaning liquid merges with the clean water and continues to rotate inside the vortex passage, so that the cleaning liquid and the clean water can be fully mixed inside the vortex passage to obtain a mixture of suitable concentration and uniformity. The active ingredients in the high-concentration cleaning liquid are completely dissolved and dispersed in the clean water, so that the cleaning liquid can be fully utilized, further ensuring the cleaning effect of grease on the inner wall of the steel pipe.

[0037] By adjusting the component, when the water flow inside the spray sleeve becomes smaller, the openings of some second water holes can be adaptively reduced, so that the sprayed water flow can be more concentrated and stable. When the water flow inside the spray sleeve becomes larger, the openings of some second water holes can be adaptively enlarged to diffuse the water flow and make the liquid coverage area wider.

Implementation

[0053] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0054] Example 1, reference Figure 1-2, which is the first embodiment of the present invention, provides a steel pipe degreasing and cleaning device, including a liquid tank 1 and a steel pipe 4, the steel pipe 4 is obliquely arranged inside the liquid tank 1, and a cleaning component for cleaning the inner wall of the steel pipe 4 is arranged inside the liquid tank 1, and the cleaning component includes a supporting component 13 arranged inside the liquid tank 1, and a brushing component 14 arranged on the supporting component 13.

[0055] Specifically, through the liquid storage tank 1, the cleaning liquid and clean water used in the cleaning process of the steel pipe 4 can be collected, which is convenient for the staff to recycle the cleaning liquid. The steel pipe 4 is tilted inside the liquid storage tank 1, and the end of the steel pipe 4 away from the brush cleaning component 14 is higher than the end of the steel pipe 4 close to the brush cleaning component 14, which can facilitate the cleaning liquid to flow downward from the inner wall of the steel pipe 4 and reduce the residual cleaning liquid on the inner wall of the steel pipe 4.

[0056] Reference Figure 1 The support assembly 13 is used to provide support for the steel pipe 4. The support assembly 13 includes an active roller 2 arranged on the inner wall of the liquid tank 1, a driven roller 3 arranged on the inner wall of the liquid tank 1, a rubber pad 5 arranged on the outer walls of the active roller 2 and the driven roller 3, and a driving motor 12 arranged on the outer wall of the liquid tank 1, and the output shaft of the driving motor 12 is fixedly connected to the axial end of the active roller 2.

[0057] Specifically, the active roller 2 is rotatably installed on the inner wall of the liquid tank 1, and the driven roller 3 is rotatably installed on the inner wall of the liquid tank 1. The active roller 2 and the driven roller 3 are both T-shaped. The steel pipe 4 is placed on the active roller 2 and the driven roller 3, which can effectively support and limit the steel pipe 4 to prevent the steel pipe 4 from falling. The rubber pad 5 is sleeved on the outer wall of the active roller 2 and the outer wall of the driven roller 3. Through the set rubber pad 5, the friction between the steel pipe 4 and the surface of the active roller 2 and the driven roller 3 can be effectively increased to prevent slipping. The drive motor 12 is fixedly installed on the outer wall of the liquid tank 1, and the output shaft of the drive motor 12 is fixedly connected to the axial end of the active roller 2.

[0058] The active roller 2 is driven to rotate by controlling the output shaft of the driving motor 12 , and the active roller 2 can drive the steel pipe 4 and the driven roller 3 to rotate synchronously when rotating.

[0059] Reference Figure 1 and Figure 2The brushing assembly 14 is used to brush the inner wall of the steel pipe 4. The brushing assembly 14 includes a reciprocating screw 6 arranged at the end of the active roller 2, a guide rod 7 arranged at the end of the driven roller 3, and a movable block 8 arranged on the outer wall of the reciprocating screw 6, and the end of the reciprocating screw 6 away from the active roller 2 is connected to the inner wall of the liquid tank 1, the end of the guide rod 7 away from the driven roller 3 is connected to the inner wall of the liquid tank 1, the inner wall of the movable block 8 is connected to the outer wall of the guide rod 7, the brushing assembly 14 also includes a water passing cylinder 9 arranged on the outer wall of the movable block 8, bristles 32 arranged on the outer wall of the water passing cylinder 9, a first connecting pipe 11 arranged on the outer wall of the water passing cylinder 9, and a first water passing hole 10 opened on the outer wall of the water passing cylinder 9.

[0060] Specifically, the reciprocating screw 6 is fixedly installed at the end of the active roller 2, and the end of the reciprocating screw 6 away from the active roller 2 is rotatably connected to the inner wall of the liquid tank 1, and the movable block 8 is connected to the outer wall of the reciprocating screw 6 by a thread. When the reciprocating screw 6 rotates, it can drive the movable block 8 to move back and forth in the direction of approaching or moving away from the steel pipe 4. The guide rod 7 is rotatably installed at the end of the driven roller 3, and the end of the guide rod 7 away from the driven roller 3 is fixedly connected to the inner wall of the liquid tank 1, and the inner wall of the movable block 8 is slidably connected to the outer wall of the guide rod 7. When the movable block 8 moves in the direction of approaching or moving away from the steel pipe 4, the cooperation between the guide rod 7 and the movable block 8 can effectively improve the stability of the movable block 8 when sliding.

[0061] The water cylinder 9 is fixedly installed on the outer wall of the movable block 8, the bristles 32 are fixedly installed on the outer wall of the water cylinder 9, the first connecting pipe 11 is inserted into the inside of the water cylinder 9, and the end of the first connecting pipe 11 away from the water cylinder 9 is connected to a cleaning liquid pipeline. This is a common water diversion technical means in the prior art and will not be elaborated on here. A plurality of first water holes 10 are provided, and the plurality of first water holes 10 are evenly distributed in an annular shape on the outer wall of the water cylinder 9.

[0062] During use, when it is necessary to clean the grease attached to the inner wall of the steel pipe 4, the staff first controls the first connecting pipe 11 to pass a grease cleaning liquid of a suitable concentration, and then the grease cleaning liquid is sprayed out from the inside of the multiple first water holes 10 through the water cylinder 9, and then the output shaft of the driving motor 12 is controlled to rotate, which can drive the active roller 2 to rotate, and then drive the steel pipe 4 and the driven roller 3 to rotate. At the same time, the rotation of the active roller 2 drives the reciprocating screw 6 to rotate, and the reciprocating screw 6 drives the movable block 8 and the water cylinder 9 to move toward the direction close to the steel pipe 4. The grease cleaning liquid is sprayed from the inside of the multiple first water holes 10 to rinse the grease on the inner wall of the steel pipe 4. Then, the bristles 32 on the outer wall of the water cylinder 9 can brush the grease residue on the inner wall of the steel pipe 4. Since the steel pipe 4 is in a state of self-rotation, the contact area between the inner wall of the steel pipe 4 and the cleaning liquid and the bristles 32 is further increased, so that the cleaning liquid and the bristles 32 can comprehensively clean the inner wall of the steel pipe 4, effectively improving the cleaning effect of the inner wall of the steel pipe 4.

[0063] Example 2, reference Figure 3-8 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that a flushing component is also provided inside the water cylinder 9, and the flushing component is used to flush the cleaning liquid remaining on the inner wall of the steel pipe 4. The flushing component includes a spraying component 15 arranged on the water cylinder 9, and a control component 16 arranged on the water cylinder 9.

[0064] Specifically, the grease cleaning liquid remaining on the inner wall of the steel pipe 4 is likely to affect the quality of the subsequent fluid. Some of the cleaning liquid may react chemically with the fluid to produce by-products or change the fluid properties, which will have an adverse effect on the requirements of the application environment. For this reason, a flushing component is provided inside the water tube 9.

[0065] Reference Figure 3-8 The spray assembly 15 is used to spray clean water or a mixture of clean water and high-concentration cleaning liquid. The spray assembly 15 includes a partition 18 arranged inside the water cylinder 9, a second connecting pipe 17 arranged on the outer wall of the water cylinder 9, and a one-way valve 42 arranged inside the second connecting pipe 17. The interior of the water cylinder 9 is divided into a cleaning liquid chamber 40 and a clean water chamber 41 by the partition 18, the second connecting pipe 17 and the cleaning liquid chamber 40 are connected to each other, and the first connecting pipe 11 and the clean water chamber 41 are connected to each other.

[0066] Specifically, the partition 18 is fixedly installed on the inner wall of the water-passing cylinder 9, and the interior of the water-passing cylinder 9 is divided into a cleaning liquid chamber 40 and a clean water chamber 41 by the partition 18. The second connecting pipe 17 is inserted into the interior of the cleaning liquid chamber 40, and the first connecting pipe 11 is inserted into the interior of the clean water chamber 41. The end of the second connecting pipe 17 away from the water-passing cylinder 9 is connected to a cleaning liquid pipeline, and the end of the first connecting pipe 11 away from the water-passing cylinder 9 is connected to a clean water pipeline. This is a common water diversion technical means in the prior art and will not be elaborated on here. The one-way valve 42 is arranged inside the second connecting pipe 17 to prevent the cleaning liquid inside the cleaning liquid chamber 40 from flowing back and affecting the purity of the external cleaning liquid water source.

[0067] In the present embodiment, a high-concentration grease cleaning liquid circulates inside the cleaning liquid chamber 40, and clean water circulates inside the clean water chamber 41. When the water-passing cylinder 9 moves toward the direction close to the steel pipe 4, the outlet of the cleaning liquid chamber 40 circulates, and the high-concentration grease cleaning liquid and the clean water merge and are converted into a grease cleaning liquid of a suitable concentration, which is sprayed out to flush the inner wall of the steel pipe 4. When the water-passing cylinder 9 moves away from the steel pipe 4, the outlet of the cleaning liquid chamber 40 is blocked, and the high-concentration cleaning liquid does not flow out. At this time, a part of the cleaning liquid originally on the inner wall of the steel pipe 4 flows downward along the inclined inner wall of the steel pipe 4, and the other part is sprayed out from the clean water chamber 41 by clean water to flush the cleaning liquid remaining on the inner wall of the steel pipe 4.

[0068] Reference Figure 3-8 The spray assembly 15 also includes a fixing ring 19 arranged on the outer wall of the water tube 9, a connecting ring 20 arranged on the outer wall of the fixing ring 19, a spray sleeve 21 arranged on the outer wall of the connecting ring 20, and a second water hole 28 opened on the outer wall of the spray sleeve 21.

[0069] Specifically, the fixing ring 19 is fixedly installed on the outer wall of the water-passing cylinder 9, the connecting ring 20 is fixedly installed on the outer wall of the fixing ring 19, and the spray sleeve 21 is rotatably installed on the outer wall of the connecting ring 20. The spray sleeve 21 and the connecting ring 20 are rotatably fitted to ensure the sealing between the spray sleeve 21 and the connecting ring 20. The second water hole 28 is inclined, and there are multiple second water holes 28. The multiple second water holes 28 are evenly distributed in an annular shape on the outer wall of the spray sleeve 21. When clean water or a mixture of clean water and cleaning liquid is sprayed out from the inside of the water-passing cylinder 9, the water flows through the multiple second water holes 28, which can drive the spray sleeve 21 to rotate, thereby effectively increasing the spraying range of the spray sleeve 21.

[0070] Reference Figure 3-8 The control component 16 is used to control the circulation of the cleaning liquid. The control component 16 includes an arc groove 31 opened on the inner wall of the fixing ring 19, a baffle 22 arranged on the outer wall of the water tube 9, and the outer wall of the baffle 22 is slidably fitted with the inner wall of the arc groove 31. The control component 16 also includes a sliding ring 23 arranged on the outer wall of the baffle 22, a groove 24 opened on the outer wall of the sliding ring 23, an arc-shaped spring piece 25 arranged inside the groove 24, a friction plate 26 arranged on the outer wall of the arc-shaped spring piece 25, an elastic member 27 sleeved on the outer wall of the water tube 9, a limit block 29 arranged on the outer wall of the water tube 9, and a limit groove 30 opened on the inner wall of the sliding ring 23, and the outer wall of the limit block 29 is slidably fitted with the inner wall of the limit groove 30.

[0071] Specifically, the position of the baffle 22 corresponds to the position of the cleaning liquid chamber 40, the inner wall of the baffle 22 slides in contact with the outer wall of the water tube 9, and the outer wall of the baffle 22 slides in contact with the inner wall of the arc groove 31, which effectively ensures the sealing between the baffle 22 and the water tube 9 and the fixing ring 19. The sliding ring 23 is fixedly installed on the outer wall of the baffle 22, and both ends of the arc-shaped spring piece 25 are fixedly connected to the inner wall of the groove 24. The outer wall of the friction plate 26 is fixedly connected to the outer wall of the arc-shaped spring piece 25. The groove 24 is set to provide deformation space for the arc-shaped spring piece 25 and the friction plate 26. Both side surfaces of the friction plate 26 are set in an arc shape. The arc-shaped spring piece 25 can provide support for the friction plate 26. When the friction plate 26 is squeezed, it can move toward the direction close to the arc-shaped spring piece 25.

[0072] The elastic member 27 can be a compression spring or elastic plate commonly used in the prior art, and is preferably a compression spring here. By setting the elastic member 27, the sliding ring 23 can have a real-time tendency to move toward the direction close to the fixed ring 19, and then the baffle 22 can have a real-time tendency to block the cleaning liquid chamber 40. The limit block 29 is fixedly installed on the outer wall of the water tube 9. Through the cooperation between the limit groove 30, the limit block 29, and the sliding ring 23, the sliding trajectory of the baffle 22 can be limited to ensure that the position between the baffle 22 and the cleaning liquid chamber 40 corresponds, thereby improving the stability of the baffle 22 when sliding.

[0073] During use, when it is necessary to clean the grease on the inner wall of the steel pipe 4, the staff will pass clean water into the first connecting pipe 11 and pass a high-concentration grease cleaning liquid into the second connecting pipe 17. Through the cooperation between the support component 13 and the brushing component 14, the water cylinder 9 can be controlled to move toward the direction close to the steel pipe 4 while controlling the rotation of the steel pipe 4. In this process, when the outer wall of the friction plate 26 is squeezed with the inner wall of the steel pipe 4, the friction plate 26 applies pressure to the arc-shaped spring sheet 25. At the same time, the sliding ring 23 is under the action of friction. Retention occurs, the baffle 22 is separated from the cleaning liquid chamber 40, and the high-concentration cleaning liquid flows out from the inside of the cleaning liquid chamber 40, and then the clean water and the high-concentration cleaning liquid merge with each other and are converted into a grease cleaning liquid of suitable concentration, which is sprayed out from the second water hole 28, driving the liquid spray sleeve 21 to rotate, flushing the inner wall of the steel pipe 4, and dissolving the grease attached to the inner wall of the steel pipe 4. When the sliding ring 23 slides to the extreme position on the outer wall of the water cylinder 9, under the push of the water cylinder 9, the sliding ring 23 drives the baffle 22 to follow the water cylinder 9 and move synchronously in the direction close to the steel pipe 4.

[0074] When the bristles 32 pass through the steel pipe 4, the friction plate 26 detaches from the inner wall of the steel pipe 4 and is reset under the action of the arc-shaped spring piece 25, and the water cylinder 9 moves away from the steel pipe 4. Then, the friction plate 26 contacts the inner wall of the steel pipe 4 again. However, at this time, the sliding ring 23 is against the fixed ring 19, and the sliding ring 23 moves synchronously with the water cylinder 9 away from the steel pipe 4. In this process, the baffle 22 always blocks the outlet of the cleaning liquid chamber 40, so that when the water cylinder 9 moves away from the steel pipe 4, the cleaning liquid does not flow out, and the clean water flows out from the inside of the clean water chamber 41 and is sprayed from the inside of the liquid spray sleeve 21 to flush the cleaning liquid remaining on the inner wall of the steel pipe 4, ensuring that the cleaning liquid on the inner wall of the steel pipe 4 is completely removed to avoid the cleaning liquid residue from having adverse effects on the steel pipe 4 and subsequent fluids.

[0075] The remaining structures are the same as those of Example 1.

[0076] Example 3, reference Figure 9-10, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that the flushing component also includes a mixing component 33, and the mixing component 33 is used to fully mix the high-concentration cleaning liquid and clean water.

[0077] The mixing assembly 33 includes a vortex passage 34 arranged on the outer wall of the fixed ring 19, and the side of the vortex passage 34 away from the fixed ring 19 is rotatably fitted with the inner wall of the spray sleeve 21. The mixing assembly 33 also includes a fixed block 35 arranged on the outer wall of the fixed ring 19, and the side of the fixed block 35 away from the fixed ring 19 is rotatably fitted with the inner wall of the spray sleeve 21.

[0078] Specifically, the vortex passage 34 is fixedly mounted on the outer wall of the fixing ring 19, and the fixed block 35 is fixedly mounted on the outer wall of the fixing ring 19. The side of the vortex passage 34 away from the fixing ring 19 is rotatably fitted with the inner wall of the spray sleeve 21, and the side of the fixed block 35 away from the fixing ring 19 is rotatably fitted with the inner wall of the spray sleeve 21, thereby ensuring the sealing inside the vortex passage 34 and effectively guiding the liquid. On the one hand, the fixed block 35 blocks one side of the water tube 9 so that the clean water can flow along the inside of the vortex passage 34. On the other hand, the fixed block 35 is inclined at a side close to the clean water chamber 41. When the clean water flows out, the collision between the clean water and the fixed block 35 can be effectively reduced.

[0079] During use, when the water tube 9 moves toward the direction close to the steel pipe 4, clean water first flows out from the clean water chamber 41, flows along the inside of the vortex passage 34, and flows through the cleaning liquid chamber 40. The baffle 22 opens, and the cleaning liquid immediately flows out from the cleaning liquid chamber 40. The cleaning liquid merges with the clean water and continues to rotate inside the vortex passage 34, so that the cleaning liquid and the clean water can be fully mixed inside the vortex passage 34 to obtain a mixture of suitable concentration and uniformity. The active ingredients in the high-concentration cleaning liquid are completely dissolved and dispersed in the clean water, and the cleaning liquid can be fully utilized, further ensuring the cleaning effect of grease on the inner wall of the steel pipe 4.

[0080] The remaining structure is the same as that of Example 2.

[0081] Example 4, reference Figure 10-13 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the flushing component includes an adjusting component 36, and the adjusting component 36 can adaptively reduce the opening of part of the second water holes 28 when the water flow inside the spray sleeve 21 becomes smaller, so that the sprayed water flow can be more concentrated and stable; when the water flow inside the spray sleeve 21 becomes larger, the opening of part of the second water holes 28 adaptively becomes larger, which can diffuse the water flow and make the liquid coverage area wider.

[0082] The adjusting assembly 36 includes a strip-shaped spring piece 37 disposed on the inner wall of the liquid spraying sleeve 21 , a push plate 39 disposed on the outer wall of the strip-shaped spring piece 37 , and a blocking block 38 disposed on the inner wall of the liquid spraying sleeve 21 .

[0083] Specifically, the strip spring piece 37 is fixedly mounted on the inner wall of the liquid spray sleeve 21, the position of the strip spring piece 37 corresponds to the position of part of the second water hole 28, the size of the strip spring piece 37 is larger than the size of the second water hole 28, and the strip spring piece 37 has a real-time tendency to block the second water hole 28. The push plate 39 is fixedly mounted on the outer wall of the strip spring piece 37, and the push plate 39 can further promote the rotation of the liquid spray sleeve 21 when the liquid flows, thereby expanding the spraying range. The blocking block 38 is fixedly mounted on the inner wall of the liquid spray sleeve 21, and the blocking block 38 can block the strip spring piece 37, so that part of the second water hole 28 always has a certain gap for water to pass through, which is beneficial for the subsequent strip spring piece 37 to be separated from the second water hole 28 when the water flow is large.

[0084] During use, when the water flow inside the spray sleeve 21 becomes smaller, due to the elastic force of the strip spring piece 37 itself, the strip spring piece 37 can increase the blocking area of ​​the part of the second water hole 28, thereby making the overall water outlet of the spray sleeve 21 smaller, so that the water flow sprayed by the spray sleeve 21 can be more concentrated and stable. On the contrary, when the water flow inside the spray sleeve 21 becomes larger, the water flow pushes the strip spring piece 37, so that the blocking area of ​​the part of the second water hole 28 by the strip spring piece 37 is reduced, so that the overall water outlet of the spray sleeve 21 is increased, thereby diffusing the water flow and making the liquid sprayed by the spray sleeve 21 cover a wider range.

[0085] The remaining structure is the same as that of Example 3.

[0086] Example 5, reference Figure 1-13 , which is a fourth embodiment of the present invention, provides: a method for using a steel pipe degreasing and cleaning device, comprising the following steps:

[0087] S1: The staff introduces clean water into the first connecting pipe 11 and introduces high-concentration grease cleaning liquid into the second connecting pipe 17. Then, the clean water first flows out from the clean water chamber 41, flows along the vortex passage 34, flows through the cleaning liquid chamber 40, passes through the water cylinder 9 and is sprayed out from the inside of the plurality of first water holes 10. The high-concentration grease cleaning liquid is blocked by the baffle 22 and does not flow out.

[0088] S2: Control the output shaft of the driving motor 12 to rotate, which can drive the active roller 2 to rotate, and then drive the steel pipe 4 and the driven roller 3 to rotate. At the same time, the rotation of the active roller 2 drives the reciprocating screw 6 to rotate, and the reciprocating screw 6 drives the movable block 8 and the water cylinder 9 to move toward the steel pipe 4. When the outer wall of the friction plate 26 is squeezed with the inner wall of the steel pipe 4, the sliding ring 23 is retained under the action of friction, and the baffle 22 is separated from the cleaning liquid chamber 40. The high-concentration cleaning liquid flows out from the inside of the cleaning liquid chamber 40, and then the cleaning liquid merges with the clean water and continues to rotate inside the vortex passage 34, so that the cleaning liquid is The liquid and the clean water can be fully mixed inside the vortex passage 34 to obtain a mixture with appropriate concentration and uniformity. Finally, the grease cleaning liquid with appropriate concentration is sprayed out from the second water hole 28, driving the liquid spraying sleeve 21 to rotate, flushing the inner wall of the steel pipe 4, and dissolving the grease attached to the inner wall of the steel pipe 4. When the sliding ring 23 slides to the limit position on the outer wall of the water cylinder 9, under the push of the water cylinder 9, the sliding ring 23 drives the baffle 22 to move synchronously with the water cylinder 9 towards the direction close to the steel pipe 4. Then, the bristles 32 on the outer wall of the water cylinder 9 can brush the grease residue on the inner wall of the steel pipe 4.

[0089] S3: When the bristles 32 completely pass through the steel pipe 4, the friction plate 26 has been separated from the inner wall of the steel pipe 4, and is reset under the action of the arc spring piece 25, and under the action of the reciprocating screw 6, it drives the water cylinder 9 to move away from the steel pipe 4, and then the friction plate 26 contacts the inner wall of the steel pipe 4 again. However, at this time, the sliding ring 23 and the fixed ring 19 are against each other, and the sliding ring 23 follows the water cylinder 9 to move synchronously away from the steel pipe 4. In this process, the baffle 22 always blocks the outlet of the cleaning liquid chamber 40, so that when the water cylinder 9 moves away from the steel pipe 4, the cleaning liquid does not flow out, and the clean water flows out from the inside of the clean water chamber 41, passes through the vortex passage 34 and is sprayed from the inside of the liquid spray sleeve 21, flushing the cleaning liquid remaining on the inner wall of the steel pipe 4, ensuring that the cleaning liquid on the inner wall of the steel pipe 4 is completely removed;

[0090] S4: In the process of cleaning the grease on the inner wall of the steel pipe 4, when the water flow inside the spray sleeve 21 becomes smaller, due to the elastic force of the strip spring piece 37 itself, the strip spring piece 37 can increase the blocking area of ​​the part of the second water hole 28, thereby making the overall water outlet of the spray sleeve 21 smaller; when the water flow inside the spray sleeve 21 becomes larger, the water flow pushes the strip spring piece 37, so that the blocking area of ​​the strip spring piece 37 on the part of the second water hole 28 is reduced, so that the overall water outlet of the spray sleeve 21 is increased.
