[0038] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0039] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0040] As described in the background technology, a cleaning device is required for cleaning the vacuum exhaust pipe. The cleaning device of the related technology includes a rod body, a scraper and a driving member. The scraper is set on the rod body, and the rod body is passed through and rotatably connected to the pipe. The driving member drives the rod body to rotate, so that the scraper rotates to scrape off impurities on the inner wall of the vacuum exhaust pipe.

[0041] However, when the impurities at a certain location on the inner wall of the pipe are thicker, when the scraper passes through the impurities, the thicker impurities are formed layer by layer on the inner wall of the pipe, which results in a stronger adhesion between the thicker impurities and the inner wall of the pipe, so that the thicker impurities block the normal movement of the scraper, making it difficult for the scraper to clean the impurities on the inner wall of the pipe by rotating.

[0042] In response to the above technical problems, the embodiment of the present application provides a pipeline cleaning device. When it is necessary to clean impurities on the inner wall of the pipeline of the single crystal furnace, the installation cylinder is connected to the connecting cylinder, so that the installation cylinder drives the rod body to be inserted into the pipeline, so that the rod body drives the scraper to abut against the inner wall of the pipeline, and the driving member drives the rod body to rotate, so that the rod body drives the scraper to rotate in the circumferential direction of the inner wall of the pipeline. When the scraper moves to a position where the impurities on the inner wall of the pipeline are thicker, the impurities can abut against the scraper. Because the diameter of the adjusting hole is larger than the diameter of the adjusting rod, the scraper drives the adjusting rod to adjust the diameter of the adjusting hole. The scraper moves in the hole so that the position of the scraper relative to the impurities can be away from the inner wall of the pipe, and the position of the scraper away from the impurities can be close to the inner wall of the pipe. The scraper is adaptively driven to tilt, so that the scraper can partially scrape off the impurities. When the scraper rotates circumferentially in the pipe, the scraper can scrape off thicker impurities multiple times from the pipe axis toward the inner wall of the pipe, thereby achieving complete cleaning of thicker impurities, thereby preventing thicker impurities from blocking the normal movement of the scraper in the pipe, and by scraping off thicker impurities multiple times, the cleaning effect of thicker impurities on the inner wall of the pipe is improved.

[0043] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0044] Combine Figures 1 to 3 , a pipeline cleaning device, comprising:

[0045] The rod body 100, part of the rod body 100 is used for rotationally connecting to the pipe 800 of the single crystal furnace;

[0046] A driving member 200 is provided on the rod body 100 and is configured to drive the rod body 100 to rotate;

[0047] The scraper 300 and the adjustment assembly 400 are provided with at least one scraper 300, and the adjustment assembly 400 is provided between the rod body 100 and the scraper 300. The adjustment assembly 400 is configured so that when the driving member 200 drives the scraper 300 to rotate circumferentially in the pipe 800, the scraper 300 is driven to tilt relative to the inner wall of the pipe 800.

[0048] In this embodiment, the scraper 300 is arranged in a long strip shape, and the cross-section of the scraper 300 is set to a rectangle; the pipeline cleaning device cleans the vacuum pipeline of the single crystal furnace; in other embodiments, the cross-sectional shape of the scraper 300 can be adaptively adjusted as needed, for example, the cross-sectional shape of the scraper 300 is set to an isosceles trapezoid or a triangle, etc., and the pipeline cleaning device can also clean the pipelines of other equipment.

[0049] By adopting the above technical solution and the setting of the adjustment component 400, when the driving member 200 drives the scraper 300 to rotate in the circumferential direction in the pipe 800, and when the scraper 300 moves to a position where the impurities on the inner wall of the pipe 800 are thicker, the adjustment component 400 can drive the scraper 300 to tilt, so that the position of the scraper 300 relative to the impurities can be away from the inner wall of the pipe 800, so that the scraper 300 can partially scrape off the impurities. When the scraper 300 rotates in the circumferential direction in the pipe 800, the scraper 300 can remove the thicker impurities from the pipe 800. The axis is scraped multiple times in the direction of the inner wall of the pipe 800, thereby achieving complete cleaning of thicker impurities, thereby preventing thicker impurities from blocking the normal movement of the scraper 300 in the pipe 800, and by scraping thicker impurities multiple times, the cleaning effect of thicker impurities on the inner wall of the pipe 800 is improved; by adopting the setting of the adjustment component 400, by driving the scraper 300 to tilt, the scraper 300 can be applied to different types of pipes 800, thereby improving the applicability of the scraper 300 and improving the cleaning effect of impurities on the inner walls of different types of pipes 800.

[0050] Combine Figures 1 to 3 At least two scrapers 300 are provided, and the two scrapers 300 are respectively provided on two opposite sides of the rod body 100 .

[0051] In this embodiment, two scrapers 300 are provided. In other embodiments, the number of scrapers 300 can be adjusted as needed, for example, the number of scrapers 300 can be set to four, and the four scrapers 300 can be evenly distributed along the circumference of the rod body 100.

[0052] By adopting the above technical solution, by setting two scrapers 300, and setting the two scrapers 300 on opposite sides of the rod body 100, the two scrapers 300 can scrape off impurities on the inner wall of the pipe 800 more times, thereby further improving the cleaning effect of impurities on the inner wall of the pipe 800; indirectly improving the cleaning efficiency of the pipe cleaning device for impurities on the inner wall of the pipe 800.

[0053] Combine Figures 1 to 3 The adjustment assembly 400 includes an adjustment rod 410 and an adjustment member 420. One end of the adjustment rod 410 is connected to one of the scrapers 300, and the other end of the adjustment rod 410 is connected to the other scraper 300. The adjustment member 420 is set on the rod body 100. The adjustment rod 410 is connected to the adjustment member 420. The adjustment member 420 is configured to drive the adjustment rod 410 to tilt when the driving member 200 drives the scraper 300 to rotate in the pipe 800, so as to drive the scraper 300 to tilt relative to the inner wall of the pipe 800.

[0054] In this embodiment, the cross-section of the adjusting rod 410 is set to be circular, and the circular adjusting rod 410 is perpendicular to the scraper 300; the adjusting assembly 400 can be replaced by multiple electric cylinders. By setting the electric cylinders on the rod body 100 and hingedly connecting the scraper 300 to the driving end of the electric cylinders, the scraper 300 can be driven to tilt by multiple electric cylinders, so that the scraper 300 tilts through the impurities, thereby achieving multiple scraping of impurities; the electric cylinder can also be replaced by a driving component such as a hydraulic cylinder; in other embodiments, the shape of the adjusting rod 410 can be adaptively adjusted as needed, for example, the cross-section of the adjusting rod 410 is set to be rectangular.

[0055] By adopting the above technical solution, by connecting the two ends of the adjustment rod 410 to the scrapers 300 on both sides respectively, and connecting the adjustment rod 410 to the adjustment member 420, the adjustment member 420 can simultaneously drive the two scrapers 300 to tilt through the adjustment rod 410. When the scraper 300 on one side scrapes thicker impurities, the scraper 300 on one side is away from the inner wall of the pipe 800, and the scraper 300 on the other side is driven to approach the inner wall of the pipe 800. Therefore, while the scraper 300 on one side scrapes the thicker impurities, the scraper 300 on the other side is driven to better abut against the inner wall of the pipe 800, thereby improving the scraping effect of the two scrapers 300 on the impurities on the inner wall of the pipe 800

[0056] Combine Figures 1 to 3 The adjusting member 420 includes an adjusting hole 421 provided on the rod body 100 , the adjusting rod 410 is passed through the adjusting hole 421 , and the diameter of the adjusting hole 421 is larger than the diameter of the adjusting rod 410 .

[0057] In this embodiment, the adjustment hole 421 is arranged in a circular shape; in other embodiments, the shape of the adjustment hole 421 can be adaptively adjusted as needed, for example, the adjustment hole 421 is set to be rectangular. By adopting a rectangular adjustment hole 421, the width of the adjustment hole 421 along the axial direction of the rod body 100 can be greater than the diameter of the adjustment rod 410, and the two sides of the adjustment rod 410 are abutted against the two sides of the adjustment hole 421, so that the rectangular adjustment hole 421 can limit the swing of the adjustment rod 410 in the vertical direction, so that the adjustment rod 410 drives the scraper 300 to tilt in the vertical direction, thereby improving the tilting effect of the scraper 300.

[0058] By adopting the above technical solution, by adopting the adjustment hole 421 and making the diameter of the adjustment hole 421 larger than the diameter of the adjustment rod 410, when the scraper 300 moves to the position where the thicker impurities are located, the impurities can drive the scraper 300 to move in the direction away from the inner wall of the pipe 800. At this time, because the diameter of the adjustment hole 421 is larger than the diameter of the adjustment rod 410, the scraper 300 drives the adjustment rod 410 to move in the adjustment hole 421, so that the adjustment rod 410 tilts in the adjustment hole 421, so that the adjustment rod 410 drives the scraper 300 on the other side to approach the inner wall of the pipe 800, so that the two scrapers 300 can clean the impurities on the inner wall of the pipe 800; by adopting the setting of the adjustment hole 421, the scraper 300 can adapt to the changes in the inner wall of the pipe 800 itself and the changes in the thickness of the impurities on the inner wall of the pipe 800 when rotating circumferentially in the pipe 800, without the need for other mechanical components to drive the scraper 300 to tilt, further improving the cleaning effect of the scraper 300 on the inner wall of the pipe 800.

[0059] Combine Figures 1 to 3 There are two adjustment holes 421 and two adjustment rods 410 . The two adjustment rods 410 are used to pass through the two adjustment holes 421 in a one-to-one correspondence. One adjustment rod 410 is set at the upper part of the scraper 300, and the other adjustment rod 410 is set at the lower part of the scraper 300.

[0060] In other embodiments, the number of adjustment rods 410 and adjustment holes 421 can be adaptively adjusted as needed. For example, three adjustment rods 410 are set, three adjustment holes 421 are set, and the three adjustment rods 410 are correspondingly inserted into the three adjustment holes 421; or the adjustment holes 421 are set as strip holes arranged along the axial direction of the rod body 100, and two adjustment rods 410 are simultaneously inserted into the same adjustment hole 421, which can also enable the adjustment hole 421 to drive the scraper 300 to tilt.

[0061] By adopting the above technical solution, by setting two adjusting rods 410, and setting the two adjusting rods 410 at the upper and lower parts of the scraper 300 respectively, the two adjusting rods 410 can prevent the scraper 300 from rotating about the adjusting rod 410 as the axis, thereby indirectly improving the abutment effect between the scraper 300 and the inner wall of the pipe 800; and by adopting the setting of two adjusting rods 410, the length of the scraper 300 can be set longer, so that the two adjusting rods 410 can have a better bearing effect on the scraper 300 with a longer length.

[0062] Combine Figures 3 and 4In this embodiment, the circular adjustment rod 410 includes a fixed rod 411 and a movable rod 412. The fixed rod 411 is connected to one of the scrapers 300, and the movable rod 412 is connected to the other scraper 300. The movable rod 412 is plugged and slidably connected in the fixed rod 411. The diameter of the fixed rod 411 is smaller than the diameter of the adjustment hole 421. A spring 413 is provided in the adjustment rod 410. The fixed rod 411 and the movable rod 412 are both hollow. One end of the spring 413 is connected to the bottom wall of the hollow fixed rod 411, and the other end is connected to the bottom wall of the hollow movable rod 412. When the rod body 100 drives the two scrapers 300 to be placed in the pipe 800, the inner wall of the pipe 800 can drive the movable rod 41 2 moves toward the fixed rod 411, so that the moving rod 412 squeezes the spring 413 and drives the spring 413 to be compressed to a compressed state. At this time, the fixed rod 411 and the moving rod 412 can rely on the elastic force in the compressed state to drive the scraper 300 to abut against the inner wall of the pipe 800. When the scraper 300 on one side abuts against thicker impurities, the adjusting rod 410 automatically retracts and contracts according to the elastic force of the spring 413, which will not affect the abutment of the scraper 300 on the other side with the inner wall of the pipe 800. In addition, the adjusting rod 410 automatically retracts and contracts according to the elastic force of the spring 413, and can also drive the scraper 300 to tilt through thicker impurities. By relying on the elastic force of the spring 413, the scraping effect of the scraper 300 on impurities is further improved.

[0063] Combine Figure 1 、 Figure 6 and Figure 7 The pipeline cleaning device also includes a connecting tube 810 and an installation tube 500. The connecting tube 810 is used to connect to the pipeline 800. The installation tube 500 is detachably connected to the connecting tube 810. The rod body 100 is passed through and rotatably connected to the installation tube 500. The rod body 100 is rotatably connected to the pipeline 800 through the installation tube 500. The driving member 200 is arranged on the installation tube 500.

[0064] In this embodiment, the cross-sections of the connecting tube 810 and the mounting tube 500 are both circular. The diameter of the circular connecting tube 810 is larger than the diameter of the circular mounting tube 500. The mounting tube 500 is solid, and the connecting tube 810 is through-set at both ends. The rod body 100 is passed through and rotatably connected to the mounting tube 500. The rod body 100 is used to rotatably connect to the connecting tube 810 and the pipe 800. The driving member 200 includes a motor, which is detachably connected to the mounting tube 50 by bolts. 0 On the side away from the connecting cylinder 810, the rod body 100 is connected to the driving end of the motor; the edges of the mounting cylinder 500 and the connecting cylinder 810 that are close to each other are both provided with flanges 900, and the flanges 900 of the mounting cylinder 500 and the flanges 900 of the connecting cylinder 810 abut against each other, and the flanges 900 of the mounting cylinder 500 and the flanges 900 of the connecting cylinder 810 are detachably connected by multiple sets of bolts and nuts. The mounting cylinder 500 and the connecting cylinder 810 are detachably connected by the flanges 900, bolts and nuts.

[0065] By adopting the above-mentioned technical solution, by adopting the connecting tube 810 and the mounting tube 500, and detachably connecting the mounting tube 500 to the connecting tube 810, when the mounting tube 500 is removed from the connecting tube 810, since the rod body 100 is passed through and rotatably connected to the mounting tube 500, and the driving member 200 is set on the mounting tube 500, the mounting tube 500 can drive the driving member 200, the rod body 100 and the scraper 300 to be taken out of the pipe 800, thereby facilitating the maintenance and replacement of the rod body 100 and the scraper 300.

[0066] Combine Figure 1 、 Figure 6 and Figure 7 The pipeline cleaning device further includes a sealing mechanism 600 , which is disposed between the connecting cylinder 810 and the mounting cylinder 500 , and is used to seal the connecting cylinder 810 and the mounting cylinder 500 .

[0067] In this embodiment, the sealing mechanism 600 includes a sealing ring 610 embedded in one of the opposite surfaces of the flange 900 of the mounting tube 500 and the flange 900 of the connecting tube 810. When the flange 900 of the mounting tube 500 and the flange 900 of the connecting tube 810 are fixed by bolts and nuts, the flange 900 can squeeze the sealing ring 610 so that the compressed sealing ring 610 seals between the mounting tube 500 and the connecting tube 810, preventing gas or impurities inside the pipeline 800 from leaking along between the mounting tube 500 and the connecting tube 810.

[0068] By adopting the above technical solution and setting up the sealing mechanism 600, the sealing mechanism 600 can seal the gap between the connecting tube 810 and the mounting tube 500, preventing the gas and impurities in the pipeline 800 from leaking along the gap between the connecting tube 810 and the mounting tube 500, thereby preventing the gas and impurities from affecting nearby personnel and the environment.

[0069] Combine Figures 2 to 5 The pipeline cleaning device further includes a material receiving mechanism 700 , which is disposed on the rod body 100 . The material receiving mechanism 700 is configured to collect impurities scraped off by the scraper 300 .

[0070] By adopting the above technical solution and the setting of the material receiving mechanism 700, when the scraper 300 scrapes off the impurities on the inner wall of the pipe 800, the scraped impurities can be collected through the material receiving trough 710. When the mounting cylinder 500 is removed from the connecting cylinder 810, since the material receiving mechanism 700 is set on the rod body 100, the rod body 100 can drive the material receiving mechanism 700 to be removed from the rod body 100, thereby facilitating the one-time cleaning of the impurities collected in the material receiving trough 710.

[0071] Combine Figures 2 to 5 The material receiving mechanism 700 includes a material receiving trough 710 and a fixing part 720 arranged on the material receiving trough 710. The material receiving trough 710 is used to collect impurities scraped off by the scraper 300. The material receiving trough 710 is sleeved and slidably connected to the rod body 100. The fixing part 720 is used to fix the material receiving trough 710 at any position on the rod body 100.

[0072] In this embodiment, the material receiving trough 710 includes a base plate 711 and an annular plate 712, and the annular plate 712 is arranged circumferentially along the edge of the base plate 711; the diameter of the base plate 711 is the same as the inner diameter of the connecting tube 810, and a sliding hole is provided at the center position of the base plate 711, and the rod body 100 is passed through the sliding hole, and the material receiving trough 710 is slidably set on the rod body 100 through the sliding hole on the base plate 711.

[0073] By adopting the above technical solution and the setting of the material receiving trough 710, the structure is simple, and more impurities can be collected through the material receiving trough 710, thereby facilitating the cleaning of more impurities at one time; by sliding the material receiving trough 710 on the rod body 100 and fixing the material receiving trough 710 with the fixing member 720, it is convenient to adjust the position of the material receiving trough 710 on the rod body 100, so that the material receiving trough 710 can collect impurities at different positions, preventing the material receiving trough 710 from affecting the normal use of the pipeline 800.

[0074] Combine Figures 2 to 5The fixing member 720 includes a sliding sleeve 721 and an adjusting bolt 722. The sliding sleeve 721 is arranged on the material receiving trough 710. The sliding sleeve 721 is sleeved and slidably connected to the rod body 100. The adjusting bolt 722 is passed through and threadedly connected to the sliding sleeve 721. The adjusting bolt 722 is used to abut against the rod body 100.

[0075] By adopting the above technical solution and the setting of the adjusting bolt 722, the material receiving trough 710 can be fixed at any position on the rod body 100 by relying on the friction between the adjusting bolt 722 and the rod body 100, thereby improving the fixing strength of the material receiving trough 710. In addition, the setting of the adjusting bolt 722 facilitates installation and disassembly by the installers, thereby improving the convenience of adjusting the position of the material receiving trough 710.

[0076] The single crystal furnace cleaning device provided by the embodiment of the present application, when it is necessary to clean impurities on the inner wall of the pipe 800 of the single crystal furnace, by connecting the installation cylinder 500 to the connecting cylinder 810, the installation cylinder 500 drives the rod body 100 to be inserted into the pipe 800, so that the rod body 100 drives the scraper 300 to abut against the inner wall of the pipe 800, and the driving member 200 drives the rod body 100 to rotate, so that the rod body 100 drives the scraper 300 to rotate along the circumferential direction of the inner wall of the pipe 800. When the scraper 300 moves to a position where the impurities on the inner wall of the pipe 800 are thicker, the impurities can abut against the scraper 300. Because the diameter of the adjustment hole 421 is larger than the diameter of the adjustment rod 410, the scraper 300 drives the adjustment rod 4 10 moves in the adjustment hole 421, so that the position of the scraper 300 relative to the impurities can be away from the inner wall of the pipe 800, and the position of the scraper 300 away from the impurities can be close to the inner wall of the pipe 800. The scraper 300 is adaptively driven to tilt, so that the scraper 300 can partially scrape off the impurities. When the scraper 300 rotates circumferentially in the pipe 800, the scraper 300 can scrape off thicker impurities multiple times from the axis of the pipe 800 toward the inner wall of the pipe 800, thereby achieving complete cleaning of the thicker impurities, thereby preventing the thicker impurities from blocking the normal movement of the scraper 300 in the pipe 800, and by scraping off the thicker impurities multiple times, the cleaning effect of the thicker impurities on the inner wall of the pipe 800 is improved.
