Description

Technical Field

[0001] The invention relates to the technical field of cleaning hollow objects, and in particular to a pipe cleaning device and a cleaning system thereof. Background Art

[0002] Pipe cleaning refers to cleaning the inner and / or outer surfaces of pipes to remove dirt and rust on the inner and outer surfaces of pipes.

[0003] In industrial production, a large number of pipe fittings are required. Before storage, a layer of oil film is brushed on the surface of the pipe fittings to isolate the surface of the pipe fittings from the air to achieve a rust-proof effect. When in use, the oil film must be cleaned off. The traditional method of cleaning oil stains on pipe fittings is the chemical cleaning agent immersion method, and it is a manual operation. This cleaning method produces a large amount of harmful waste liquid, and manual cleaning is inefficient and labor-intensive.

[0004] In the prior art, for example, Chinese patent document CN102989827A discloses an off-line degreasing and cleaning device for steel pipes, comprising a shell having a steel pipe inlet and an outlet, the shell being divided into a degreasing section, a cleaning section and an air-drying section from the inlet to the outlet, the degreasing section being provided with a degreasing brush mechanism for brushing the outer surface of the steel pipe, at least one degreasing liquid sprayer for spraying degreasing liquid onto the steel pipe being provided on both sides of the degreasing brush mechanism. This cleaning device can only clean the outer surface of the steel pipe, and cannot be cleaned when there is oil stain on the inner surface of the steel pipe.

[0005] In order to clean the inner surface of a steel pipe, Chinese patent document CN203044567U discloses a set of online internal and external degreasing and cleaning equipment for steel pipes, including an external degreasing and cleaning device and an internal degreasing and cleaning device. The designed internal degreasing and cleaning device includes a fixed internal degreasing machine and a movable internal degreasing machine respectively used to connect the two ends of the steel pipe. The fixed internal degreasing machine includes a frame, a first cleaning device, and a clamping and locking device for fixing the steel pipe. The first cleaning device also includes a first quick-connect sealing valve, a high-pressure pump, and a first propulsion mechanism; the movable internal degreasing machine includes a frame, a second cleaning device, and a connecting device that enables the steel pipe to be accurately connected to the second cleaning device.

[0006] The above-mentioned complete set of online internal and external degreasing and cleaning equipment for steel pipes degreases, cleans and air-dries the outer surface of the steel pipe, and then degreases, cleans and air-dries the inner surface of the steel pipe. After two air-dryings, the operation is relatively complicated. In addition, when degreasing the inner surface of the steel pipe, one side of the steel pipe is sealed, and cleaning liquid is introduced into the steel pipe on the other side for cleaning. Once the sealing valve leaks, the outer surface of the steel pipe that has been air-dried will also be contaminated, and the outer surface of the steel pipe must be degreased, cleaned and air-dried again, which seriously reduces the work efficiency. Summary of the invention

The guide hook is fixedly arranged on the movable transmission box and moves with the movement of the movable transmission box. The transition frame is connected to two adjacent pipe cleaning devices, one end of which is arranged close to the pipe turning hook, and the other end is arranged close to the guide hook, and is used to receive the pipe turned over by the pipe turning hook and transport the pipe to the guide hook.

[0019] The pipe cleaning system also includes a leakage trough, a water collecting trough, a water storage trough, and a return pump.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0042] Embodiment 1

[0043] The pipe cleaning device of this embodiment is as follows Figure 1 As shown, it includes a movable transmission box 11, a fixed transmission box 6, a first cleaning box 10 and a high-pressure cleaning machine 31. The first cleaning box 10 is arranged between the movable transmission box 11 and the fixed transmission box 6. The movable transmission box 11 is provided with a first transmission mechanism 12 and a third transmission mechanism 13. The third transmission mechanism 13 is located above the first transmission mechanism 12. The fixed transmission box 6 is provided with a second transmission mechanism 7. The first cleaning box 10 is provided with a first cleaning component. The box walls of the movable transmission box 11, the fixed transmission box 6 and the first cleaning box 10 can prevent the cleaning solution from splashing or dripping to the surroundings.

[0044] The movable transmission box 11 is controlled to move up and down by a control mechanism, which includes a first cylinder 14 and a bracket. The bracket is supported at the bottom of the movable transmission box 11, and the first cylinder is fixedly connected to the bracket. The height of the movable transmission box 11 can be adjusted by the telescopic action of the first cylinder 14.

[0045] like Figure 2 , Figure 3As shown, the first cleaning component includes an outer nozzle 19, a mounting body 21 and a core 22. There are two outer nozzles 19, which are symmetrically arranged in the first cleaning box 10. The mounting body 21 is installed in the first cleaning box 10 and has a cavity. The core 22 is fixedly arranged in the cavity. The core 22 has a channel 23 that is clearance-matched with the pipe 9. The pipe 9 can be inserted into the channel 23. There are multiple cores 22, and multiple cores 22 have the same outer diameter and channels 23 with different inner diameters. Channels 23 with different inner diameters can allow pipes 9 of different sizes to pass through, so that the pipe cleaning device of the present invention is suitable for cleaning pipes 9 of different sizes and has a wide cleaning range; moreover, multiple cores 22 have the same outer diameter, which can facilitate the replacement of the cores 22. Of course, the number of outer nozzles 19 is set according to the use requirements, and can also be set to three, four, etc.

[0046] The pipe cleaning device also includes a second cleaning assembly, which includes a cleaning pipeline 8 and an inner nozzle 20 arranged at the end of the cleaning pipeline 8, wherein the inner nozzle 20 is located in a channel 23 on a mold core 22, and one end of the cleaning pipeline 8 is laid on the channel 23, and the other end is fixed in a fixed transmission box 6. The fixed transmission box 6 plays a fixed supporting role for the cleaning pipeline 8, and the channel 23 plays a supporting role for the cleaning pipeline 8, so that the cleaning pipeline 8 is not easy to shake when the cleaning solution is sprayed, and the cleaning pipeline 8 can be accurately extended into the pipe 9 to be cleaned.

[0047] As a convertible embodiment, multiple inner nozzles 20 are evenly arranged along the extension direction of the cleaning pipeline 8. Multiple inner nozzles 20 clean the pipe fittings, which can increase the cleaning effect. However, it is necessary to set the opening working time of each inner nozzle 20 to avoid wasting the cleaning solution. The first transmission mechanism 12, the second transmission mechanism 7 and the third transmission mechanism 13 include multiple horizontally arranged rollers and a driving motor for driving the rollers to rotate.

[0048] like Figure 1 - Figure 3As shown, when cleaning the pipe fitting 9, the first cylinder 14 telescopes and drives the movable transmission box 11 to move, so that the first transmission mechanism 12 in the movable transmission box 11 and the second transmission mechanism 7 in the fixed transmission box 6 are flush, and the pipe fitting 9 to be cleaned is placed on the first transmission mechanism 12, the motor rotates forward, the first transmission mechanism 12 and the second transmission mechanism 7 are driven forward, the inner nozzle 20 is located upstream of the outer nozzle 19, and the first transmission mechanism 12 transports the pipe fitting 9 to the second transmission mechanism 7. When the pipe fitting 9 enters the first cleaning box 10, it passes through the through hole on the mold core 22, and the cleaning pipeline 8 and the inner nozzle 20 enter the inner wall of the pipe fitting 9 to clean the inner wall of the pipe fitting 9, and then passes through the outer nozzle 19 on the first cleaning box 10. The outer nozzle 19 cleans the outer wall of the pipe fitting 9, and the cleaned part of the pipe fitting 9 enters the fixed transmission box 6 and is placed on the second transmission mechanism 7 until all the pipe fittings 9 enter the fixed transmission box 6.

[0049] As a convertible embodiment, the inner nozzle 20 can be located downstream of the outer nozzle 19, and the first transmission mechanism 12 transports the pipe 9 to the second transmission mechanism 7. When the pipe 9 enters the first cleaning box 10, it passes through the outer nozzle 19 on the first cleaning box 10 to clean the outer wall of the pipe 9. The pipe 9 then passes through the through hole on the mold core 22, and the cleaning pipeline 8 and the inner nozzle 20 enter the inner wall of the pipe 9 to clean the inner wall of the pipe 9. The cleaned part of the pipe 9 enters the fixed transmission box 6 and is placed on the second transmission mechanism 7 until all the pipe 9 enters the fixed transmission box 6.

[0050] Then, the first cylinder 14 extends and retracts to drive the movable transmission box 11 to move, so that the third transmission mechanism 13 in the movable transmission box 11 and the second transmission mechanism 7 in the fixed transmission box 6 are aligned, and the motor is reversed to make the third transmission mechanism 13 and the second transmission mechanism 7 reversely transmit, and the first cleaning assembly and the second cleaning assembly clean the outer wall and the inner wall of the pipe 9 respectively, and the pipe 9 is cleaned back and forth twice, with good cleaning effect, and the inner wall and the outer wall of the pipe 9 are cleaned at the same time, with high cleaning efficiency.

[0051] When the pipe 9 is located on the first transmission mechanism 12, the dirt on the outer wall of the pipe 9 when it was not cleaned has been contaminated onto the first transmission mechanism 12, and the third transmission mechanism 13 receives the cleaned pipe 9. The third transmission mechanism 13 is clean and is located above the first transmission mechanism 12. The dust and dirt on the first transmission mechanism 12 will not fall onto the third transmission mechanism 13. Therefore, transmitting the cleaned pipe 9 to the third transmission mechanism 13 can prevent it from being contaminated by dirt, thereby achieving a better cleaning effect.

[0052] Embodiment 2

[0053] The pipe cleaning system of this embodiment is as follows: Figure 4As shown, it includes three groups of pipe cleaning devices as described in Example 1, namely a cleaning line 1, a rinsing line 2 and an anti-rust line 3.

[0054] The cleaning solution on the cleaning line 1 is a mixture of environmentally friendly cleaning agent and water in a certain proportion, the cleaning solution on the rinsing line 2 is water, and the cleaning solution on the anti-rust line 3 is a mixture of anti-rust agent and water in a certain proportion. Using three cleaning lines can clean the pipe fittings according to needs to achieve the required cleaning effect.

[0055] like Figure 5 , Figure 6 As shown, the pipe cleaning system includes a connecting mechanism for transferring the pipe 9 from the cleaning line 1 to the adjacent rinsing line 2, and transferring the pipe on the rinsing line 2 to the adjacent rust prevention line 3. The connecting mechanism includes a pipe turning mechanism, a transition frame 4 and a guide hook 26, wherein the pipe turning mechanism further includes a second cylinder 24 and a pipe turning hook 25.

[0056] The transition frame 4 is connected between two adjacent cleaning devices, and a stopper 27 is provided at one end thereof close to the guide hook 26.

[0057] The pipe turning hook 25 is arranged on the movable transmission box of the pipe cleaning device, one end of which is connected to the second cylinder 24, a certain point in the middle is hinged to the movable transmission box 11, and the other end is V-shaped.

[0058] like Figure 6 As shown, when the tube turning hook 25 is in the initial position, the V-shaped portion of the tube turning hook 25 is located below the roller of the third transmission mechanism 13, and there is a gap between the V-shaped portion and the pipe fitting 9 located on the roller. When the tube turning operation is performed, the second cylinder 24 contracts, the V-shaped portion of the tube turning hook 25 rises, and the pipe fitting 9 abuts against the V-shaped portion and is lifted up by the V-shaped portion.

[0059] like Figure 7 As shown, when the tube turning hook 25 is in the tube turning state, the turning hook is arranged close to the transition frame, and the tube turning hook 25 turns the tube 9 from the roller of the third transmission mechanism 13 of the cleaning line 1 to the transition frame 4, and is blocked by the block 27, the movable transmission box 11 on the rinsing line 2 rises, and the guide hook 26 on the movable transmission box 11 on the rinsing line 2 rises, and the guide hook 26 pushes the first tube 9 that abuts against the block 27, and the first tube 9 is on the guide hook 26 and rolls onto the first transmission mechanism 12.

[0060] like Figure 8As shown, the pipe cleaning system also includes a loading rack 5, which includes a first storage area 28 and a second storage area 29. When the loading rack 5 is in the initial position, the first storage area 28, the second storage area 29 and the guide hook 26 are arranged in sequence, and the end of the first storage area 28 close to the second storage area 29 is lower than the second storage area 29, and the end of the guide hook 26 close to the second storage area 29 is lower than the second storage area 29. Sensors are provided on the second storage area 29 and the movable transmission box 11.

[0061] During loading, the cleaned pipe fittings 9 are placed in the first storage area 28, and a third cylinder 30 is installed at the bottom of the first storage area 28 near one end of the second storage area 29. When the sensor detects that there are no pipe fittings 9 on the second storage area 29, the third cylinder 30 extends to make the pipe fittings 9 in the first storage area 28 roll onto the second storage area 29. The second storage area 29 has a set inclination angle, and the pipe fittings 9 are arranged in a single row in the second storage area 29. A stopper 27 is provided at one end of the second storage area 29 near the movable transmission box 11. When the movable transmission box 11 is in place, the guide hook 26 is located below the first pipe fitting 9 that is abutted against the stopper 27. When the sensor detects that there are no pipe fittings 9 on the first transmission mechanism 12, the movable transmission box 11 rises, and the guide hook 26 pushes the first pipe fitting 9. The first pipe fitting 9 is on the guide hook 26 and rolls onto the first transmission mechanism 12.

[0062] like Figure 1 As shown, the pipe cleaning system also includes a water leakage tank 15, a water collection tank 16, a water storage tank 18 and a return water pump 17.

[0063] The leakage trough 15 is arranged along the bottom of the movable transmission box 11 and the fixed transmission box 6, and is connected to the inner cavity of the movable transmission box 11 and the fixed transmission box 6. The collecting trough 16 is connected to the leakage trough 15 and the first cleaning box 10, and is used to collect the waste liquid in the leakage trough 15 and the first cleaning box 10. A purification device is provided in the water collecting trough 16, and a steam heating pipe is provided inside the water storage tank 18, which is connected to the first cleaning component and the second cleaning component.
