Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology in petrochemical industry, specifically to a pipeline cleaning device for petrochemical industry. Background Technology

[0002] A search revealed existing technology (application number: CN202123242974.5), which describes "This utility model proposes a cleaning device for petrochemical pipelines, comprising a base, a connecting shaft, a mounting shaft, a rotating base, rollers, a support arm unit, a sleeve, and a cleaning plate. The radial position of the rollers can be adjusted via a threaded connection between the mounting shaft and the base, allowing the rollers to slide over pipelines of different inner diameters. Movement of the sleeve along the connecting shaft causes rotation between the first and second support arms, allowing the cleaning plate at the end of the second support arm to radially contract or expand, thus enabling it to conform to the inner walls of oil pipelines of different inner diameters for cleaning. Therefore, this device can simultaneously achieve radial adjustment of the roller unit and the cleaning plate in the circumferential direction, expanding the range of sizes of the pipeline inner walls that can be cleaned." This utility model allows for adjustment of the rollers and cleaning plate to accommodate different pipe diameters.

[0003] However, while existing technologies can adapt to different pipe diameters, they still have some shortcomings: limited cleaning effect. Utility Model Content

[0007] The displacement adjustment assembly includes: a limiting sleeve, fixedly mounted at one end of the scraper support, for guiding the threaded sleeve; a threaded rod, rotatably mounted at one end of the scraper support and disposed within the limiting sleeve, for driving the threaded sleeve to move; a throttle, fixedly mounted at one end of the threaded rod away from the scraper support, for driving the threaded rod to rotate; and a threaded sleeve, threaded outside the threaded rod and slidably disposed within a groove on the limiting sleeve, for driving the scissor lift to move.

[0008] As a further description of the above technical solution:

[0009] The scissor lift assembly includes: a second scissor lift rod, fixedly mounted on a threaded sleeve, for adjusting the height of the wall scraping plate; a first scissor lift, rotatably mounted on the second scissor lift rod and rotatably mounted on the connecting block of the wall scraping support; and a slider, rotatably mounted on the first scissor lift via a bottom connecting block and disposed within a groove of the wall scraping plate, for adjusting the height of the wall scraping plate.

[0010] As a further description of the above technical solution:

[0011] The wall scraping assembly includes: a wall scraping plate with a connecting block at the bottom that is rotatably connected to a scissor fork, used for scraping the walls of petrochemical pipelines; and rollers rotatably mounted on the wall scraping plate to drive the wall scraping plate to move.

[0012] As a further description of the above technical solution:

[0013] The cleaning fluid spraying assembly includes: a trough, which is located at one end inside the wall scraping support column and is used to guide the cleaning fluid; and multiple sets of drain pipes, which are fixedly installed on the wall scraping support column and connected to the trough, for spraying the cleaning fluid.

[0014] As a further description of the above technical solution:

[0015] The cleaning assembly includes: a clamping base, comprising two sets, one set fixedly mounted on the scraping support column at the end away from the drain pipe, and the other set fixedly mounted on the water pipe at the end close to the brush disc, for supporting the rotating shaft, and having slots for guiding cleaning fluid from the water pipe into the slots, and then spraying it out from the drain pipe; a rotating shaft, rotatably mounted on the clamping base, for supporting the rotation of the fan blades; fan blades, evenly mounted on the rotating shaft, for driving the brush disc to rotate using fluid power; a brush disc, fixedly mounted on the outside of the fan blades and rotatably mounted outside the two sets of clamping bases, for driving the brushes to rotate; and multiple brushes, evenly fixedly mounted on the brush disc, for cleaning the pipe wall.

[0016] As a further description of the above technical solution:

[0017] The washing assembly also includes a water pipe, fixed to one end of a clamping base away from the brush disc, for inputting cleaning fluid.

[0018] This utility model has the following beneficial effects:

[0019] 1. Highly Flexible Pipe Diameter Adaptability: The displacement adjustment component within the height adjustment assembly allows the threaded rod to rotate by turning the handle, which in turn drives the threaded sleeve to slide precisely within the limiting sleeve. This enables fine-tuning of the horizontal position of the scissor lift. Combined with four ring-shaped scissor lift components, the height of the scraping assembly can be adjusted omnidirectionally and with high precision. This feature allows the cleaning device to easily handle petrochemical pipelines of varying diameters. Whether the pipe diameter is conventional or varies, it ensures the scraping assembly fits tightly against the inner wall of the pipe, greatly expanding the device's applicability and improving the versatility and efficiency of cleaning operations.

[0020] 2. Highly Efficient and Collaborative Cleaning Process: The scrubbing components are ingeniously designed. The cleaning fluid spraying component guides the cleaning fluid to the drain pipe through a channel, achieving comprehensive and uniform spraying of the inner wall of the pipeline, effectively softening and initially decomposing the dirt on the pipe wall. The brushing component uses hydrodynamics to drive the fan blades to rotate, which in turn drives the brush disc and bristles to rotate at high speed, deeply cleaning the pipe wall that has been sprayed with cleaning fluid. The spraying and brushing steps work closely together, softening first and then scrubbing, significantly improving the quality and effectiveness of pipeline cleaning, ensuring that the dirt on the inner wall of the pipeline is thoroughly removed, and guaranteeing the normal operation and service life of petrochemical pipelines.

[0033] Example 1:

[0034] like Figures 1 to 4As shown, this embodiment provides a pipeline cleaning device for petrochemicals, comprising: a height adjustment component 1, including a scraping support column 101, fixedly mounted on the inner side of the scraping plate 201 via a scissor bar 103, a displacement adjustment component mounted at one end of the scraping support column 101 for adjusting the horizontal position of the scissor bar 104, and four sets of scissor assemblies arranged in a ring on the scraping support column 101 for connecting the height adjustment component 1 and the scraping component 2 and adjusting the height of the scraping component 2; four sets of scraping components 2, arranged in a ring on the outer side of the height adjustment component 1, for scraping the walls of the petrochemical pipeline 4; a washing component 3, including a cleaning fluid spraying component mounted on the scraping support column 101 for spraying cleaning fluid onto the pipe wall, and a cleaning brushing component mounted at one end of the scraping support column 101 for cleaning and washing the pipe wall after spraying the cleaning fluid; and a petrochemical pipeline 4, wherein the height adjustment component 1, the scraping component 2, and the washing component 3 are placed inside the petrochemical pipeline 4.

[0035] The petrochemical pipeline cleaning device involved in this application achieves efficient cleaning of petrochemical pipelines.

[0036] In this embodiment, the horizontal position of the scissor bar 104 is adjusted by the displacement adjustment component, and the height of the wall scraping component 2 is adjusted by the scissor bar component.

[0037] It should be noted that the scraper support 101 is made of high-strength alloy steel, which has good rigidity and corrosion resistance. The scissor lift rod 103 is made of stainless steel to ensure structural strength and rust resistance.

[0038] Specifically, the displacement adjustment assembly includes: a limiting sleeve 106, fixedly disposed at one end of the scraper support 101, for guiding the threaded sleeve 105; a threaded rod 107, rotatably disposed at one end of the scraper support 101 and disposed within the limiting sleeve 106, for driving the threaded sleeve 105 to move; a throttle 108, fixedly disposed at one end of the threaded rod 107 away from the scraper support 101, for driving the threaded rod 107 to rotate; and a threaded sleeve 105, threaded outside the threaded rod 107 and slidably disposed in a groove opened on the limiting sleeve 106, for driving the scissor lift lever 104 to move.

[0039] In this embodiment, rotating the throttle 108 causes the threaded rod 107 to rotate, and the threaded sleeve 105 moves linearly under constraint.

[0040] It should be noted that the limiting sleeve 106 is made of stainless steel. The threaded rod 107 is made of high-strength alloy steel and is used to drive the displacement of the threaded sleeve 105. The throttle 108 is made of cast iron and is fixed to one end of the threaded rod 107 away from the scraper support 101, which facilitates manual operation to rotate the threaded rod 107.

[0041] Specifically, the scissor lift assembly includes: a second scissor lift 104, fixedly mounted on a threaded sleeve 105, used to adjust the height of the scraper plate 201; a first scissor lift 103, rotatably mounted on the second scissor lift 104 and rotatably mounted on the connecting block of the scraper support 101; and a slider 102, rotatably mounted on the first scissor lift 103 via a bottom connecting block and located within the groove of the scraper plate 201, used to adjust the height of the scraper plate 201.

[0042] In this embodiment, the threaded sleeve 105 moves to drive the second scissor bar 104, causing the first scissor bar 103 to rotate, and the slider 102 slides in engagement.

[0043] The second scissor lift 104 is made of stainless steel and is used to adjust the height of the scraper plate 201. The connector is also made of stainless steel. The slider 102 is made of stainless steel and is rotatably mounted on the first scissor lift 103 via the bottom connecting block. It is positioned within the groove of the scraper plate 201 to assist in adjusting the height of the scraper plate 201.

[0044] Specifically, the wall scraping assembly 2 includes: a wall scraping plate 201, with a connecting block at the bottom that is rotatably connected to the scissor bar 104, for scraping the wall of the petrochemical pipeline 4; and a roller 202, which is rotatably mounted on the wall scraping plate 201 and is used to drive the wall scraping plate 201 to move.

[0045] In this embodiment, when the device moves, the roller 202 rolls and the scraping plate 201 contacts the inner wall of the pipe to scrape away dirt.

[0046] Four sets are arranged in a ring around the outside of the height adjustment component 1. The scraping plate 201 is made of hard alloy and is used to scrape the walls of the petrochemical pipeline 4. The roller 202 is a rubber-coated metal hub structure that is rotatably mounted on the scraping plate 201, driving the scraping plate 201 to move.

[0047] Example 2:

[0048] Based on Example 1, in order to further improve the decontamination capability of the device, a cleaning liquid spraying component is provided.

[0049] Specifically, the cleaning fluid spraying assembly includes: a trough 307, which is located at one end inside the wall scraping support 101 and is used to guide the cleaning fluid; and multiple sets of drain pipes 308, which are fixedly installed on the wall scraping support 101 and connected to the trough 307, for spraying the cleaning fluid.

[0050] In a preferred embodiment, the cleaning fluid flows through the tank 307 to the drain pipe 308 and is sprayed out.

[0051] Spray the cleaning solution evenly onto the inner wall of the pipe to better rinse away any excess dirt left by scraping.

[0052] The pipe groove 307 is located inside one end of the scraper support 101. The material of the scraper support 101 ensures the sealing and durability of the pipe groove 307. The drain pipe 308 consists of multiple steel pipes, which are fixedly installed on the scraper support 101 and connected to the pipe groove 307, and are used to spray cleaning fluid.

[0053] Example 3:

[0054] Based on Example 2, in order to simultaneously clean the walls of petrochemical pipes, a cleaning component is brushed on one side of the cleaning fluid spraying component.

[0055] Specifically, the cleaning assembly includes: a clamping base 306, comprising two sets, one set fixedly mounted on the scraping support column 101 at one end away from the drain pipe 308, and the other set fixedly mounted on the water pipe 305 at one end close to the brush disc 302, for supporting the rotating shaft 304, and having slots for guiding cleaning fluid from the water pipe 305 into the pipe groove 307, and then spraying it out from the drain pipe 308; a rotating shaft 304 rotatably mounted on the clamping base 306 for supporting the rotation of the fan blade 303; fan blades 303 evenly mounted on the rotating shaft 304 for driving the brush disc 302 to rotate using fluid power; a brush disc 302 fixedly mounted on the outside of the fan blades 303 and rotatably mounted outside the two sets of clamping bases 306 for driving the brush 301 to rotate; and multiple sets of brushes 301 evenly fixedly mounted on the brush disc 302 for cleaning the pipe wall.

[0056] In this embodiment, the flow of cleaning fluid drives the fan blades 303, which in turn rotates the brush disc 302 and the brush 301. This allows for further cleaning of the pipe wall after the cleaning fluid has been sprayed.

[0057] It should be noted that there are two sets of clamping bases 306, made of cast iron, used to support the rotating shaft 304. The rotating shaft 304 is a stainless steel shaft, rotatably mounted on the clamping base 306, supporting the rotation of the fan blade 303. The fan blades 303 are made of cast iron and are evenly distributed on the rotating shaft 304, driving the brush disc 302 to rotate using hydrodynamic power. The brush disc 302 is made of aluminum alloy and drives the brush 301 to rotate. The brush 301 is made of nylon and is used to clean the pipe wall.

[0058] Specifically, the washing assembly 3 also includes a water pipe 305, which is fixed to one end of a clamping base 306 away from the brush plate 302, for inputting cleaning fluid.

[0059] In this embodiment, a high-pressure water pump delivers the cleaning fluid into the device through a water pipe 305.

[0060] It should be noted that the water pipe 303 is made of polyethylene, which allows for better propulsion of the cleaning fluid and the device.

[0061] When using the device to clean the petrochemical pipeline 4, the device needs to be adjusted to a suitable height. The operator rotates the handle 108, which drives the threaded rod 107 to rotate. The threaded rod 107 drives the threaded sleeve 105 to restrict its displacement in the groove of the limiting sleeve 106. The threaded sleeve 105 drives the scissor fork rod 104 and scissor fork rod 103 to swing. The wall scraping support 101 drives the slider 102 to slide. The scissor fork rod 104 and slider 102 drive the wall scraping plate 201 to move. When the desired height is reached, stop rotating the handle 108. After adjusting the width, place the height adjustment component 1, the wall scraping component 2, and the scrubbing component 3 into the petrochemical pipeline 4. At this time, the cleaning fluid is injected into the scrubbing component through a high-pressure water pump. Inside component 3, cleaning fluid flows into brush plate 302 through water pipe 305, then into pipe groove 307 through brush plate 302, and finally into drain pipe 308 through pipe groove 307. The drain pipe 308 sprays cleaning fluid onto the pipe wall. While spraying cleaning fluid, the cleaning fluid flows through water pipe 305, and under the action of the fluid dynamics, it drives fan blade 303 to rotate. Fan blade 303 drives brush plate 302 to rotate, and brush plate 302 drives brush 301 to rotate, thereby sweeping and cleaning the pipe wall. During cleaning, the staff pushes water pipe 305, which drives the washing component 3 to move. The washing component 3, with the help of roller 202, drives the wall scraping component 2 to move and scrape the wall for cleaning through height adjustment component 1.

[0062] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
