Description

Technical Field

[0001] The invention belongs to the field of stainless steel pipe cleaning, and more specifically, relates to a device for cleaning oil stains on the surface of a stainless steel pipe. Background Art

[0002] Existing equipment usually uses clean water to clean stainless steel pipes, but the inner wall of stainless steel pipes is usually difficult to clean. There are two common ways to spray the inside of stainless steel pipes. The first is to use a spray gun to spray water into the inside of one end of the stainless steel pipe. The wall near the end will be fully washed, while the wall near the middle of the stainless steel pipe is cleaned by water flowing from the end. However, this part of the water will be mixed with the oil remaining on the end wall, making it difficult to clean the middle wall of the stainless steel pipe.

[0003] The second method is to insert a long water pipe into the stainless steel pipe to flush the stainless steel pipe. The disadvantage of this solution is that the water pipe is long, which leads to a large overall footprint of the equipment and is not easy to install. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a device for cleaning oil stains on the surface of a stainless steel pipe, which can clean various positions of the stainless steel pipe and occupies a small space.

[0005] The present invention discloses a device for cleaning oil stains on the surface of a stainless steel pipe, comprising an oil-water separation barrel and a cleaning tank; two groups of symmetrically arranged cleaning mechanisms are installed in the cleaning tank; the cleaning mechanisms comprise a conveyor belt for transporting the stainless steel pipe, a rotating pipe rotatably connected in the cleaning tank, and a plurality of retractable disks fixedly connected to the outer wall of the rotating pipe; a water spray pipe is wound around each of the retractable disks; one end of the water spray pipe is connected to the inside of the rotating pipe, and the other end is provided with water spray ports distributed along the circumferential direction.

[0006] As a further improvement of the present invention, the water spray pipe is a plastic hose; a sphere is provided at one end of the water spray pipe close to the water spray outlet; a support plate is fixedly connected to the conveyor belt; a through hole is provided on the support plate for the water spray pipe to pass through; the diameter of the through hole is smaller than the diameter of the sphere.

[0007] As a further improvement of the present invention, a cover plate is provided at the upper end of the cleaning pool; a spray plate is provided at the lower end of the cover plate; spray holes are evenly arranged on the spray plate; and a water pump for injecting water into the spray plate and the rotating tube is provided on one side of the cleaning pool.

[0008] As a further improvement of the present invention, the cleaning mechanism further comprises a lower pressing frame which slides longitudinally in the cleaning tank; a plurality of rollers for driving the stainless steel pipe to rotate are rotatably connected to the lower pressing frame.

[0009] As a further improvement of the present invention, each of the rollers is connected by a synchronous belt transmission; the rollers are connected by a rotating tube; and the cleaning mechanism also includes an electric push rod that drives the lower pressure frame to move longitudinally.

[0010] As a further improvement of the present invention, the cleaning mechanism also includes a feed tray rotating in the cleaning pool; the feed tray is evenly provided with feed troughs along the circumference; one feed trough accommodates a stainless steel pipe; the conveyor belt is provided with a conveyor belt gear for driving the conveyor belt to work; the cleaning mechanism also includes an incomplete gear that can engage with the feed tray and the conveyor belt gear; at the same time, the incomplete gear only drives one of the feed tray and the conveyor belt gear to work.

[0011] As a further improvement of the present invention, a plurality of receiving grooves for placing stainless steel pipes are evenly arranged on the conveyor belt; when the conveyor belt is working, each receiving groove moves along the circumference of the conveyor belt; and a rolling column is rotatably connected in the receiving groove.

[0012] As a further improvement of the present invention, the cleaning mechanism also includes a motor and a switching gear arranged on the output shaft of the motor; the output shaft of the motor and the switching gear rotate synchronously in the circumferential direction and slide relative to each other in the axial direction; a driving gear is coaxially arranged on the incomplete gear; an end gear is coaxially arranged on the side wall of the rotating tube; when the switching gear is in the first position, the switching gear is meshed with the driving gear; when the switching gear is in the second position, the switching gear is meshed with the end gear.

[0013] As a further improvement of the present invention, a switching frame is slidably connected in the cleaning tank to drive the switching gear to move axially; an inclined switching ramp is provided on the switching frame; a downward pressure rod is provided on the downward pressure frame to resist the switching ramp; and a spring for resetting the switching frame is provided between the switching frame and the cleaning tank.

[0014] As a further improvement of the present invention, a discharge port is provided on one side of the cleaning tank; and a drainage pump for discharging sewage into the oil-water separation barrel is provided in the cleaning tank.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: this solution provides a water spray pipe, which can be stored on a retractable tray, thereby reducing the footprint of the water spray pipe and reducing the overall length of the cleaning pool; at the same time, the water spray pipe can also enter the interior of the stainless steel pipe to clean various positions inside the stainless steel pipe, and various positions inside the stainless steel pipe will be cleaned by the clean water sprayed from the water spray port, thereby improving the cleaning efficiency.

[0016] In this solution, the rotation of the rotating tube can drive the various rollers to rotate, so that the various rollers drive the stainless steel tube to rotate, which is convenient for cleaning various positions of the stainless steel tube. It can also drive the retractable disk to rotate, and through the forward and reverse rotation of the rotating tube, the movement of the water spray pipe in the stainless steel tube is controlled, which is convenient for the water spray pipe to clean the inside of the stainless steel tube.

[0017] The incomplete gear in this solution can not only drive the feed tray to rotate, but also drive the conveyor belt to work. Through the cooperation between the feed tray and the conveyor belt, the stainless steel pipes are arranged in each receiving slot in turn, waiting to be cleaned.

[0018] The switching gear of the present invention can drive both the incomplete gear and the rotating tube to rotate. There is no need for two motors to drive the incomplete gear and the rotating tube to rotate respectively, which reduces the setting of electrical components and saves costs.

[0019] This solution enables the lower pressure frame to longitudinally move so that the driving roller of the lower pressure frame is against the stainless steel pipe, thereby facilitating the rotation of the stainless steel pipe. The lower pressure rod can also be used to drive the switching gear to move axially, thereby facilitating the switching gear to switch between the first position and the second position. No additional electrical components are required to drive the switching gear to move, thereby saving costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The water spray pipe 34 is a plastic hose; a sphere 342 is provided at one end of the water spray pipe 34 close to the water spray port 341; a support plate 24 is fixedly connected to the conveyor belt 2; a through hole 241 is provided on the support plate 24 for the water spray pipe 34 to pass through; the diameter of the through hole 241 is smaller than the diameter of the sphere 342.

[0024] When the water spray pipe 34 enters the stainless steel pipe 14 , the sphere 342 contacts the wall of the stainless steel pipe 14 , thereby creating a gap between each water spray port 341 and the wall of the stainless steel pipe 14 , making it easier for water to spray out from the water spray port 341 .

[0025] When the retractable plate 33 retracts the water spray pipe 34 , the sphere 342 will eventually abut against the through hole 241 to prevent the water spray pipe 34 from being separated from the abutment plate 24 . At this time, the sphere 342 is directly opposite to the stainless steel pipe 14 .

[0026] A cover plate 13 is disposed at the upper end of the cleaning pool 12 ; a spray plate 16 is disposed at the lower end of the cover plate 13 ; spray holes are evenly disposed on the spray plate 16 ; a water pump for injecting water into the spray plate 16 and the rotating tube 3 is disposed on one side of the cleaning pool 12 .

[0027] A water-passing seat 32 rotatably connected to the rotating tube 3 is fixedly connected in the cleaning pool 12 ; the water-passing seat 32 is connected to the water outlet end of the water pump.

[0028] The cleaning mechanism further comprises a lower pressing frame 6 which slides longitudinally in the cleaning tank 12 ; a plurality of rollers 61 which are rotatably connected to the lower pressing frame 6 and are used to drive the stainless steel pipe 14 to rotate.

[0029] The rollers 61 are connected to each other through a synchronous belt 62; the rollers 61 are connected to the rotating tube 3; the cleaning mechanism also includes an electric push rod 15 for driving the lower pressure frame 6 to move longitudinally.

[0030] The lower pressure frame 6 is rotatably connected with a synchronous belt gear 63 meshing with the synchronous belt 62; the lower pressure frame 6 is rotatably connected with a first connecting gear 64 meshing with the synchronous belt gear 63; a rotating gear 35 is coaxially arranged on the outer wall of the rotating tube 3; the lower pressure frame 6 is provided with a second connecting gear 65 meshing with the rotating gear 35; the first connecting gear 64 and the second connecting gear 65 are connected via a first driving belt transmission.

[0031] The cleaning mechanism also includes a feed tray 4 that rotates in the cleaning pool 12; the feed tray 4 is evenly provided with feed grooves 41 along the circumferential direction; one feed groove 41 accommodates a stainless steel tube 14; the conveyor belt 2 is provided with a conveyor belt gear 21 that drives the conveyor belt 2 to work; the cleaning mechanism also includes an incomplete gear 5 that can mesh with the feed tray 4 and the conveyor belt gear 21; at the same time, the incomplete gear 5 only drives one of the feed tray 4 and the conveyor belt gear 21 to work.

[0032] A feed gear 42 capable of meshing with the incomplete gear 5 is coaxially arranged on the feed tray 4 ; a feed port 131 for the stainless steel pipe 14 to fall into the feed trough 41 is arranged between the cleaning pool 12 and the cover plate 13 .

[0033] The conveyor belt 2 is evenly provided with a plurality of receiving grooves 22 for placing the stainless steel pipes 14 ; when the conveyor belt 2 is working, each receiving groove 22 moves circumferentially along the conveyor belt 2 ; a rolling column 23 is rotatably connected in the receiving groove 22 .

[0034] When a stainless steel tube 14 is located in the receiving groove 22 , the stainless steel tube 14 abuts against the rolling column 23 , thereby reducing the friction force when the stainless steel tube 14 rotates.

[0035] During one rotation of the incomplete gear 5, the incomplete gear 5 first drives the conveyor belt 2 to work for a certain distance, so that an empty receiving slot 22 moves to one side of the feed tray 4, and then the incomplete gear 5 drives the feed tray 4 to rotate, and a feed slot 41 with a stainless steel tube 14 is rotated to a horizontal level, and then the stainless steel tube 14 in the feed slot 41 moves to the receiving slot 22. As the incomplete gear 5 continues to rotate, the conveyor belt 2 and the feed tray 4 work intermittently, and then gradually transport the stainless steel tube 14 in the feed port 131 to the receiving slot 22 through the feed slot 41 in sequence, and multiple stainless steel tubes 14 waiting to be cleaned are placed on the upper end of the conveyor belt 2.

[0036] The cleaning mechanism also includes a motor 73 and a switching gear 71 arranged on the output shaft of the motor 73; the output shaft of the motor 73 and the switching gear 71 rotate synchronously in the circumferential direction and slide relative to each other in the axial direction; a driving gear 51 is coaxially arranged on the incomplete gear 5; an end gear 31 is coaxially arranged on the side wall of the rotating tube 3; when the switching gear 71 is in the first position, the switching gear 71 is meshed with the driving gear 51; when the switching gear 71 is in the second position, the switching gear 71 is meshed with the end gear 31.

[0037] The cleaning pool 12 is provided with a sealed cavity for placing the motor 73 to prevent the motor 73 from contacting water.

[0038] A switching rack 72 is slidably connected in the cleaning tank 12 to drive the switching gear 71 to move axially; an inclined switching slope 721 is provided on the switching rack 72; a lower pressure rod 66 is provided on the lower pressure rack 6 to abut against the switching slope 721; a spring for resetting the switching rack 72 is provided between the switching rack 72 and the cleaning tank 12.

[0039] When the lower pressure frame 6 is located at the upper limit position, the roller 61 is located above each stainless steel tube 14 and does not hinder the operation of the conveyor belt 2. The spring makes the switching frame 72 located in the first position, and then the switching frame 72 drives the switching gear 71 to be synchronously located in the first position; when the lower pressure frame 6 is located at the lower limit position, the roller 61 abuts against the stainless steel tube 14, and the lower pressure rod 66 abuts against the switching inclined surface 721, forcing the switching frame 72 to move to the second position, and then the switching frame 72 drives the switching gear 71 to be synchronously located in the second position, and at the same time the second connecting gear 65 engages with the rotating gear 35.

[0040] A discharge port 132 is provided at one side of the cleaning tank 12 ; a drainage pump for discharging sewage into the oil-water separation barrel 11 is provided in the cleaning tank 12 .

[0041] Initially, the lower pressing frame 6 is located at the upper limit position, the switching gear 71 is meshed with the driving gear 51 , and the water spray pipe 34 is stored on the storage tray 33 .

[0042] When the cleaning machine 12 is working, the worker places the stainless steel pipe 14 at the feed port 131, and then the motor 73 drives the switching gear 71 to rotate, and then the incomplete gear 5 continues to rotate. The stainless steel pipes 14 are sequentially transported to the receiving tank 22 through the feed trough 41. As the incomplete gear 5 rotates, the stainless steel pipe 14 that needs to be cleaned finally moves to the position facing the ball 342.

[0043] Then the electric push rod 15 works to move the lower pressure frame 6 to the lower limit position, each roller 61 abuts against the corresponding stainless steel pipe 14, and the lower pressure rod 66 drives the switching frame 72 and the switching gear 71 to move to the second position, the switching gear 71 engages with the end face gear 31, and the rotating gear 35 engages with the second connecting gear 65.

[0044] Then the motor 73 works forward for a set time, and the switching gear 71 drives the rotating tube 3 to rotate forward. The rotating tube 3 drives each roller 61 to rotate synchronously through the rotating gear 35, and the roller 61 drives each stainless steel tube 14 to rotate. As the rotating tube 3 rotates forward, the retractable disk 33 rotates forward synchronously, forcing the water spraying tube 34 to gradually move toward the center of the stainless steel tube 14, and the ball 342 enters the stainless steel tube 14 and moves.

[0045] At the same time, the water pump works, and part of the water is sprayed from the spray plate 16 onto the stainless steel pipe 14, and the other part of the water passes through the rotating tube 3 and the water spray pipe 34 and is finally sprayed out from the water spray port 341, and as the water spray port 341 gradually moves toward the center of the stainless steel pipe 14, the water sprayed from the water spray port 341 sprays and cleans various positions on the inner wall of the stainless steel pipe 14.

[0046] After the set time is reached, the water spray port 341 moves to the center of the stainless steel pipe 14, and then the two cleaning mechanisms clean all positions inside the stainless steel pipe 14. Then the motor 73 works in the reverse direction for the set time, the retractable disc 33 retracts the water spray pipe 34, and then the water spray port 341 gradually moves to the outside of the stainless steel pipe 14 to clean the stainless steel pipe 14 again. The motor 73 works back and forth multiple times to achieve deep cleaning of the stainless steel pipe 14.

[0047] After cleaning is completed, the motor 73 works to store the water spray pipe 34 on the storage tray 33, and the electric push rod 15 works to move the lower pressing frame 6 to the upper limit position. Then the motor 73 drives the incomplete gear 5 to work, so that the next batch of stainless steel pipes 14 move to the position opposite to the sphere 342. The cleaned stainless steel pipes 14 will fall into the discharge port 132, waiting for the workers to take them away.

[0048] The above process is repeated to continuously clean the stainless steel tube 14 in batches.

[0049] Example 2: Please refer to Figure 7A device for cleaning oil stains on the surface of a stainless steel pipe is provided. This embodiment makes the following improvements on the basis of the first embodiment: a guide pipe 25 connected to the through hole 241 is fixedly connected to the abutment plate 24; the water spray pipe 34 passes through the guide pipe 25. When the retractable disk 33 drives the water spray pipe 34 to move toward the center of the stainless steel pipe 14, the guide pipe 25 can prevent the water spray pipe 34 from accumulating at the position of the retractable disk 33.
