Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and more specifically to a petrochemical pipeline cleaning device and method. Background Technology

[0002] The existing technologies for petrochemical pipeline cleaning equipment have formed a diversified development pattern. Mechanical cleaning devices dominate, such as intelligent cleaning equipment that uses a drive motor to move rollers and a servo motor to drive the brush rotation. These devices can penetrate deep into the pipeline to efficiently remove grease, wax, and chemical residues. Some devices are adapted to different pipe diameters through threaded adjustment mechanisms, making them widely applicable. High-pressure water jet technology uses a high-pressure pump to generate a high-speed water flow, combined with an adjustable-angle nozzle to achieve all-round rinsing, especially suitable for removing hard scale. Ultrasonic cleaning machines, relying on the physical cavitation effect, efficiently remove impurities from the inner wall of the pipeline in a short time without the need for chemical agents, meeting environmental protection requirements. Pipeline cleaning technology is further classified according to pipeline conditions, including steel brush type, foam brush type, gel type, and intelligent detection type, which can achieve multi-functional integration of cleaning, isolation, and detection. In addition, automated cleaning lines integrate modules such as length measurement, weighing, and marking, combined with industrial robots and vision recognition systems, significantly improving cleaning accuracy and production efficiency, and have become the preferred solution for large petrochemical enterprises.

[0003] Chinese patent publication number CN116550704A discloses a petrochemical pipeline cleaning device and its usage method, including a housing. A conveying pipe is rotatably connected to the middle of the housing. One end of the conveying pipe is connected to an external water source through a rotary joint. A water distribution plate is fixedly connected to the end of the conveying pipe away from the rotary joint. Diverting pipes are fixedly connected at equal intervals to the outer side of the water distribution plate. Water is sprayed out through the telescopic pipe and cleaning brush by setting a telescopic pipe and a cleaning brush. The cleaning brush rotates to clean the inner wall, cleaning and rinsing simultaneously. A reciprocating electric cylinder drives a drive rack to move up and down, which drives a swing rod to swing the air drying pipe back and forth, so that hot air dries the inner wall, achieving rapid drying of the interior. The water is drawn out by a water collection tank and a second fan through a scraper adhering to the inner wall of the pipe, and then discharged through the pipe, facilitating the recycling and collection of the used water.

The high-pressure cleaning gun 9 and the camera 10 are existing structures, and the specific structure and connection method of the high-pressure cleaning gun 9 and the camera 10 will not be described in detail in this embodiment.

[0029] Reference Figure 1 The lifting assembly 1 includes a movable base plate 102, with rollers 101 rotatably connected to the bottom of the movable base plate 102.

[0030] In this embodiment, it should be specifically explained that: when the hydraulic cylinder 108 is started, the piston rod of the hydraulic cylinder 108 extends, causing the top plate 109 to rise. The rise of the top plate 109 causes the fixed rod block 104 to pull the hinge rod 105 to rotate, causing the sliding block rod 106 to slide inside the guide rail plate 103. When the center of the rotating ring 7 is aligned with the center of the pipe, the hydraulic cylinder 108 stops.

[0031] Reference Figure 1The moving component 2 includes a first motor 201. The housing of the first motor 201 is fixedly connected to the top plate 109. The rotating shaft of the first motor 201 is fixedly connected to a gear 202. A rack 203 is meshed with the bottom of the gear 202. A T-block is fixedly connected to the bottom of the rack 203. The T-block of the rack 203 is slidably connected to the T-slot of the top plate 109. A second motor 3 is fixedly connected to one end of the rack 203.

[0032] In this embodiment, it should be specifically explained that when the first motor 201 is started, the first motor 201 drives the gear 202 to rotate, which in turn drives the rack 203 and the rotating ring 7 to move into the pipe.

[0033] Reference Figure 2 and Figure 3 The pressure assembly 4 includes a first pressing part 401. A pressure rod 402 is fixedly connected to the bottom of the first pressing part 401. A transverse limiting rod 403 is fixedly connected to one side of the pressure rod 402. A first spring 404 is sleeved on the outside of the pressure rod 402.

[0034] In this embodiment, it should be specifically explained that: when the first pressing part 401 is pressed, the first pressing part 401 descends, compressing the first spring 404 and the first telescopic protection rod 405 to retract. As the first pressing part 401 continues to descend, during the descent of the first pressing part 401, the first pressing part 401 compresses the hydraulic oil inside the pressure hole 705 to move towards the pressure receiving hole 709.

[0035] Reference Figure 2 and Figure 6 The scraper assembly 5 includes a housing 502, a scraper head 505 fixedly connected to the top of the housing 502, the scraper head 505 being triangular in shape, multiple stop holes 504 provided on the left and right sides of the housing 502, hook holes 503 passing through the upper and lower sides of the housing 502, and multiple second springs 501 installed inside the housing 502, one end of the second spring 501 being fixedly connected to the bottom of the scraper head 505, and the other end of the second spring 501 being fixedly connected to the protruding block 702.

[0036] In this embodiment, it should be specifically noted that there are multiple stop holes 504, and the stop holes 504 and hook blocks 603 correspond to different pipe inner diameters when they are fixed together.

[0037] Reference Figure 1 , Figure 2 , Figure 5 and Figure 7The upper and lower ends of the protruding block 702 are provided with hook holes 703, the upper and lower ends of the annular block 701 are provided with force application holes 708, the upper and lower sides of the inner side of the annular block 701 are provided with guide grooves 704, the guide grooves 704 are also located inside the protruding block 702, the guide grooves 704 connect the annular block 701 and the protruding block 702, the guide grooves 704 are connected to the force application holes 708 and the hook holes 703, the inner side of the guide grooves 704 is provided with L-shaped grooves 706, the L-shaped grooves 706 are slidably connected to the limiting rod 403, the middle of the protruding block 702 is provided with a stepped hole 707, the large hole of the stepped hole 707 is slidably sealed to the hook block 603, and the small hole of the stepped hole 707 obstructs the extension of the stop block 601.

[0038] In this embodiment, it should be specifically noted that: the annular block 701 is fixedly connected to the rotating shaft of the second motor 3, and the guide groove 704 is divided into a turning part and a straight part.

[0039] Reference Figure 2 and Figure 4 The hook hole assembly 8 includes a second pressing part 801. A guide rod 804 is fixedly connected to one end of the second pressing part 801 near the rotating ring 7. A fourth spring 802 is sleeved on the outside of the guide rod 804. A second telescopic protection rod 803 is provided on the outside of the fourth spring 802. The second telescopic protection rod 803 is located between the second pressing part 801 and the ring block 701. A bend 805 is fixedly connected to one end of the guide rod 804 near the rotating ring 7. Connecting parts 806 are fixedly connected to both sides of the bend 805. A hook rod 807 is fixedly connected to one end of the connecting part 806 away from the rotating ring 7. The hook rod 807 is slidably connected to the hook hole 703. The bend 805 is slidably connected to the turning part of the guide groove 704. The connecting part 806 is slidably connected to the straight part of the guide groove 704.

[0040] In this embodiment, it should be specifically explained that after the scraper assembly 5 and part of the rotating ring 7 enter the inside of the pipe, the second pressing part 801 at both ends of the rotating ring 7 is pressed. The second pressing part 801 compresses the fourth spring 802 and causes it to contract. The hook rod 807 contracts until the hook rod 807 disengages from the hook hole 503. The scraper head 505 contacts the inner wall of the pipe under the elastic release action of the second spring 501.

[0041] The specific steps are as follows: First, the petrochemical pipeline to be cleaned is horizontally fixed. Camera 10 is activated to obtain the center height information of the pipeline. Hydraulic cylinder 108 is started, and the piston rod of hydraulic cylinder 108 extends, causing the top plate 109 to rise. The rise of the top plate 109 causes the fixed rod block 104 to pull the hinge rod 105 to rotate, causing the sliding block rod 106 to slide inside the guide rail plate 103. The center of the rotating ring 7 is aligned with the center of the pipeline. Hydraulic cylinder 108 stops, and the first motor 201 is started. The first motor 201 drives the gear 202 to rotate, driving the rack 203 and the rotating ring 7 towards the pipeline. As the scraper assembly 5 and a portion of the rotating ring 7 move into the pipe, the second pressing parts 801 at both ends of the rotating ring 7 are pressed. The second pressing parts 801 compress the fourth spring 802, causing it to contract. The hook rod 807 contracts until it disengages from the hook hole 503. The scraper head 505 contacts the inner wall of the pipe under the elastic release of the second spring 501. At this time, the extension length of the scraper assembly 5 matches the inner diameter of the pipe, and the hook block 603 corresponds to the stop hole 504. The first pressing part 401 is then pressed, and the first pressing part 401 and the stop hole 504 are activated. As rod 403 descends, the first pressing part 401 descends along the pressure hole 705, and the limiting rod 403 descends along the vertical groove of the L-shaped groove 706, compressing the first spring 404 and the first telescopic protection rod 405 to retract. When the first pressing part 401 descends to a certain distance, rotating the first pressing part 401 drives the limiting rod 403 into the transverse groove of the L-shaped groove 706. Since the pressure rod 402 is only subjected to the upward force of the hydraulic oil, and this force is perpendicular to the limiting rod 403, the limiting rod 403 can only move up and down, thus achieving the locking of the pressure rod 402 and the limiting rod 403. If the first pressing part 401 cannot continue to descend or rise, during the descent of the first pressing part 401, the first pressing part 401 presses the hydraulic oil inside the pressure hole 705 to move towards the pressure receiving hole 709. Then, the pressure of the hydraulic oil on the stop block 601 and hook block 603 increases continuously. The hydraulic oil directly presses the stop block 601 and hook block 603 to bulge outward. During this process, the third spring 602 is compressed and contracts until the hook block 603 passes through the stop hole 504 of the corresponding pipe diameter stop and fixes the scraper assembly 5. At this time, the scraper assembly 5 is in a non-elastic scraper state. The second motor 3 is started, driving the scraper assembly 5 to rotate. The scraper assembly 5 performs preliminary cleaning of the hard scale layer on the inner wall of the pipe. After one rotation of cleaning is completed, the first motor 201 is started, driving the rack 203 and scraper assembly 5 to move forward one position. During this process, the high-pressure cleaning gun 9 is started. The rotation of the high-pressure cleaning gun 9 cleans the preliminarily cleaned inner wall of the pipe, removing residual debris and exposing the scale layer that has not been peeled off. After the inner wall of the pipe has been cleaned in sequence, the first pressing part 401 is rotated, driving the limiting rod 403 to move out of the transverse groove of the L-shaped groove 706. Then, under the elastic action of the first spring 404, the first pressing part 401 and the limiting rod 403 return to their original positions, realizing pressure When lever 402 is released, the elastic force of the third spring 602 is greater than the pressure of the hydraulic oil on the stop block 601. Subsequently, under the elastic action of the third spring 602, the hook block 603 leaves the stop hole 504 and resets, losing its fixation on the stop hole 504. The hydraulic oil also flows back under the movement of the hook block 603. At this time, the scraper assembly 5 is in the elastic scraper state. The second motor 3 is started, and the second motor 3 drives the scraper head 505 to perform a fine sweep on the inner wall of the pipe. The pipe wall is cleaned with low pressure rotation to remove the fine particles and edge burrs remaining after high-pressure water rinsing. After a week of cleaning is completed, the first motor 201 is started, which drives the second spring 501 to move back and continue cleaning until all the inner walls of the pipe are cleaned. When dealing with pipes of different diameters, the hydraulic cylinder 108 is still activated and aligned with the center of the pipe. When the second spring 501 reaches the inside of the pipe, the second pressing part 801 is pressed, the scraper head 505 is released, the extension length of the scraper assembly 5 matches the inner diameter of the pipe, and the first pressing part 401 is pressed, so that the hook block 603 fixes the scraper head 505, and the cleaning action continues. The specific operation steps are as above.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
