Description

Technical Field

[0001] The present invention relates to the field of cleaning devices, and particularly to a surface degreasing device for stainless steel pipe production. Background Art

[0002] In the manufacturing and production process of stainless steel pipes, a large amount of lubricating oil and coolant are required, which are easily adhered to the surface of the stainless steel pipes. Since stainless steel pipes are often used in fields such as food and chemical industry, before the stainless steel pipes are sold, the steel pipes usually need to be thoroughly degreased and cleaned.

[0003] The existing degreasing methods for stainless steel pipes include chemical degreasing, solvent degreasing and hot water degreasing. No matter which degreasing method is used, basically a large number of stainless steel pipes are bundled in the middle, and through a hoisting device, the bundled stainless steel pipes are immersed in a cleaning tank. There is generally aeration equipment in the cleaning tank to thoroughly clean the stainless steel pipes.

[0004] Although the above method can degrease and clean a large number of stainless steel pipes at one time, it is inevitable that there will be incomplete cleaning due to stacking when degreasing the bundled stainless steel pipes. Summary of the Invention

Fourth motors are fixed on the outer sides of the cleaning tanks. The motor shafts of the fourth motors are fixed to cam shafts. The cam shafts are rotatably arranged between the two side walls of the cleaning cavity, and a pair of cams are fixed on the cam shafts.

[0021] In summary, the present invention has the following beneficial effects:

[0022] 1. At least a pair of support brackets are fixed on the outer side of the outer cleaning tank of the present application. The support brackets are used to support the bundled stainless steel pipes. A moving seat is installed on the moving track, and the moving seat is driven by a first power component to move along the moving track. A slide rail is fixedly installed on the moving seat, and a sliding seat is installed on the slide rail. The sliding seat is driven by a second power component to move along the slide rail. A lifting track is fixed on one side of the sliding seat. A lifting channel is opened in the lifting track, and a lifting seat is slidably installed in the lifting channel. The lifting seat is driven by a lifting component to move along the lifting channel. A clamping head is installed on one side of the lifting seat. A clamping groove facing the cleaning tank is opened in the clamping head. After the bundled stainless steel pipes are placed on the outermost support brackets and the bundling is released, the two clamping heads approach each other under the drive of the second power component, so that the two ends of the stainless steel pipe are respectively inserted into the two clamping grooves. Then the clamping head is lifted by the lifting component, and the stainless steel pipes will automatically spread out in a non-overlapping state under the action of their own gravity. A cleaning cavity with an open top is opened in each cleaning tank. Connecting rails are fixed on both sides of the cleaning cavity. A connecting channel with an open top is opened in the connecting rail. The connecting channel has the same shape as the lifting channel. After the clamping head holds the stainless steel pipe, the connecting channel is aligned with the lifting channel by the first power component and the second power component. At this time, the lifting component is started simultaneously to put the two lifting seats into the connecting channel, so as to drive the stainless steel pipe into the first cleaning tank for degreasing cleaning operation. After completing the cleaning for a specified time in the first cleaning tank, the lifting seat is pulled back into the lifting channel by controlling the lifting component, so as to take out the stainless steel pipe from the first cleaning tank. Then the first power component is continuously driven to align the connecting channel with the lifting channel in the second cleaning tank, so as to carry out degreasing cleaning in the second cleaning tank.

[0023] Thus, while cleaning a large number of stainless steel pipes, it can also ensure that the stainless steel pipes are in a scattered state, there is no cleaning dead angle, and the cleaning is more thorough.

[0024] 2. At least two support brackets are also fixed on one side of the last cleaning tank. The support brackets facilitate the bundling of the stainless steel pipes after all cleaning is completed.

[0025] 3. An activity cavity is opened in the lifting seat. An activity block is slidably installed in the activity cavity. Springs are installed between both sides of the activity block and the inner wall of the activity cavity. A clamping head is fixed on one side of the activity block. Fourth motors are fixed on the outer side of the cleaning tank. The motor shafts of the fourth motors are fixed to the camshaft. The camshaft is rotatably arranged between the two side walls of the cleaning cavity. A pair of cams are fixed on the camshaft. After the clamping head drives the stainless steel pipe into the cleaning cavity, the fourth motors are controlled by the control box to start, so as to drive the camshaft to rotate. The camshaft drives the cams to rotate. When the cams rotate, they will continuously push the two clamping heads to move repeatedly (cooperating with the springs, the springs will be continuously compressed and reset), so that the steel pipes between the two clamping heads roll continuously under the action of inertia, improving the degreasing cleaning effect.

[0034] Combined with the attached Figures 1 - 6 The surface degreasing device for stainless steel pipe production described above includes at least two cleaning tanks 11 and a pair of mobile rails 21 arranged on both sides of the cleaning tanks 11. The outermost cleaning tank 11 is used to add lye for alkali washing of the stainless steel pipe, and the other cleaning tanks 11 are used to add clean water for water washing of the stainless steel pipe. The lye and clean water need to be replaced regularly, which is realized by an external water circulation system (not shown in the drawings of the present application as it is not relevant to this application);

[0035] At least a pair of supporting brackets 12 are fixed on the outer side of the outermost cleaning tank 11. The supporting brackets 12 are used to support the bundled stainless steel pipes. Generally, only the middle part of the stainless steel pipes is bundled, and it is manually bundled by workers. After bundling, the bundled stainless steel pipes are placed on the outermost supporting brackets 12 by a hoisting device / forklift. After completion, the workers need to manually remove the bundled part;

[0036] A moving seat 50 is installed on the moving rail 21. The moving seat 50 is driven by a first power assembly to move along the moving rail 21. The first power assembly includes a moving block 27 slidably installed in the moving rail 21. The moving block 27 is fixed to the moving seat 50. A first lead screw 24 passes through the moving block 27. The first lead screw 24 is rotatably installed in the moving rail 21. Threads are provided on both the moving block 27 and the first lead screw 24 and are threadedly connected to each other. The first lead screw 24 is fixed to the motor shaft of a first motor 25. The first motor 25 is fixedly installed on the moving rail 21. After the first motor 25 is started, it drives the first lead screw 24 to rotate, and drives the moving block 27 to move along the moving rail 21 through the threaded connection between the first lead screw 24 and the moving block 27. The moving block 27 drives the moving seat 50 to move along the moving rail 21;

[0037] A slide rail 46 is fixedly installed on the moving seat 50. A slide seat 18 is installed on the slide rail 46. The slide seat 18 is driven by a second power assembly to move along the slide rail 46. The second power assembly includes a slider 45 slidably installed in the slide rail 46. The slider 45 is fixed to the slide seat 18. A second lead screw 47 passes through the slider 45. The second lead screw 47 is rotatably installed in the slide rail 46. Threads are provided on both the second lead screw 47 and the slider 45 and are threadedly connected to each other. One end of the second lead screw 47 is fixed to the motor shaft of a second motor 36. The second motor 36 is fixedly installed on the moving seat 50 through a base 35. After the second motor 36 is started, it drives the second lead screw 47 to rotate, and drives the slider 45 to move along the slide rail 46 through the threaded connection between the second lead screw 47 and the slider 45;

[0038] On one side of the sliding seat 18, a lifting rail 17 is fixed. A lifting path 44 is defined within the lifting rail 17. A lifting seat 16 is slidably installed within the lifting path 44. The lifting seat 16 is driven by a lifting assembly to move along the lifting path 44. The lifting assembly includes a bracket 51 fixedly provided on the moving seat 50. A pair of fixed seats 34 are fixedly installed on the bracket 51. A third motor 33 is fixedly installed on one of the fixed seats 34. A winding shaft 32 is fixedly connected to the motor shaft of the third motor 33. The other end of the winding shaft 32 is rotatably connected to the other fixed seat 34. A winding cylinder 31 is fixedly provided on the winding shaft 32. A rope 29 is wound around the winding cylinder 31. One end of the rope 29 is fixed to the lifting seat 16. At least one fixed pulley 30 is fixed on the bracket 51. The fixed pulley 30 is used to guide the rope 29. After the third motor 33 is started, it drives the winding cylinder 31 to rotate. After the winding cylinder 31 rotates, it winds or unwinds the rope 29, causing the lifting seat 16 to move along the lifting path 44;

[0039] A clamping head 15 is installed on one side of the lifting seat 16. A clamping groove 42 facing the cleaning tank 11 is defined within the clamping head 15. After the bundled stainless steel pipes are placed on the outermost support bracket 12 and the bundling is removed, the two clamping heads 15 are driven by the second power assembly to approach each other, so as to insert the two ends of the stainless steel pipe into the two clamping grooves 42 respectively. Then the clamping head 15 is lifted by the lifting assembly. Under the action of its own gravity, the stainless steel pipes will automatically spread out in a non-overlapping state;

[0040] A cleaning chamber 14 with an open top is defined within each cleaning tank 11. Connecting rails 19 are fixed on both sides of the cleaning chamber 14. A connecting path 20 with an open top is defined within the connecting rail 19. The connecting path 20 has the same shape as the lifting path 44. After the clamping head 15 holds up the stainless steel pipe, the connecting path 20 is aligned with the lifting path 44 through the first power assembly and the second power assembly. At this time, the lifting assembly is started simultaneously to place the two lifting seats 16 into the connecting path 20, thereby driving the stainless steel pipe into the first cleaning tank 11 for degreasing cleaning operations;

[0041] After the cleaning within the first cleaning tank 11 is completed within a specified time, the lifting seat 16 is pulled back into the lifting path 44 by controlling the lifting assembly, thereby taking the stainless steel pipe out of the first cleaning tank 11. The first power assembly is continuously driven to align the connecting path 20 with the lifting path 44 within the second cleaning tank 11, so as to perform degreasing cleaning within the second cleaning tank 11.

[0042] On one side of the last cleaning tank 11, at least two supporting brackets 12 are also fixed, and the supporting brackets 12 facilitate the bundling of the stainless steel pipes after all cleaning is completed.

[0043] The two first power components of this application work simultaneously, the two second power components of this application work simultaneously, and the two lifting components of this application also work simultaneously. It is realized through control program programming, and a control box 22 is fixed on the moving rail 21 for control.

[0044] A distribution box 23 is also fixed on the moving rail 21, and the distribution box 23 supplies power to each electrical component of this application through wires (the circuit is relatively complex and is not convenient to show in the drawings).

[0045] To optimize the cleaning effect, an aerator 13 is installed at the bottom inside the cleaning chamber 14 to enable the cleaning liquid to fully contact the stainless steel pipes (it is a conventional technology in the industry, and the aerator can be purchased according to actual needs).

[0046] To further optimize the cleaning effect, a movable cavity 48 is opened inside the lifting seat 16. A movable block 43 is slidably installed in the movable cavity 48. Springs 49 are installed between both sides of the movable block 43 and the inner wall of the movable cavity 48. A clamping head 15 is fixed on one side of the movable block 43. Fourth motors 41 are fixed outside the cleaning tanks 11. The motor shafts of the fourth motors 41 are fixed to a camshaft 39. The camshaft 39 is rotatably arranged between the two side walls of the cleaning chamber 14. A pair of cams 40 are fixed on the camshaft 39. After the clamping head 15 drives the stainless steel pipe into the cleaning chamber 14, the fourth motor 41 will be controlled by the control box 22 to start, driving the camshaft 39 to rotate. The camshaft 39 drives the cams 40 to rotate. When the cams 40 rotate, they will continuously push the two clamping heads 15 to move back and forth (cooperating with the springs 49, and the springs 49 will continuously compress and reset), causing the steel pipe between the two clamping heads 15 to continuously roll under the action of inertia, improving the oil removal and cleaning effect.

[0047] Usage method:

[0048] When in use, first place the bundled stainless steel pipes on the outermost supporting bracket 12 through a hoisting device / forklift. After completion, the worker needs to manually remove the bundling part;

[0049] After completion, the two clamping heads 15 approach each other under the drive of the second power component, thereby inserting the two ends of the stainless steel pipe into the two clamping grooves 42 respectively. Then the clamping heads 15 are lifted by the lifting component, and the stainless steel pipe will automatically spread out in a non-overlapping state under its own gravity;

[0050] The working mode of the second power assembly is as follows: the second motor 36 is controlled by the control box 22 to start. After starting, it drives the second lead screw 47 to rotate. By the threaded connection between the second lead screw 47 and the slider 45, the slider 45 is driven to move along the slide rail 46, and the clamping head 15 moves along with the slide rail 46;

[0051] After completion, the connection channel 20 and the lifting channel 44 are aligned by the first power assembly and the second power assembly. At this time, the lifting assembly is started simultaneously to place the two lifting seats 16 into the connection channel 20, thereby driving the stainless steel pipe into the first cleaning tank 11 for degreasing and cleaning operations;

[0052] The working mode of the first power assembly is as follows: the control box 22 controls the first motor 25 to start and then drives the first lead screw 24 to rotate. By the threaded connection between the first lead screw 24 and the moving block 27, the moving block 27 is driven to move along the moving rail 21, and the moving block 27 drives the moving seat 50 to move along the moving rail 21. The clamping head 15 and the clamped stainless steel pipe move along with the moving seat 50;

[0053] After the cleaning in the first cleaning tank 11 is completed within the specified time, the lifting seat 16 is pulled back into the lifting channel 44 by controlling the lifting assembly, thereby taking out the stainless steel pipe from the first cleaning tank 11. Then, the first power assembly is continuously driven to align the connection channel 20 with the lifting channel 44 in the second cleaning tank 11, so as to perform degreasing and cleaning in the second cleaning tank 11.

[0054] At least two supporting brackets 12 are also fixed on one side of the last cleaning tank 11. The supporting brackets 12 facilitate the bundling of the stainless steel pipe after all the cleaning is completed.
