Technical Field
[0001] The present application relates to the technical field of pipeline cleaning, and in particular to a dust prevention device for pipeline cleaning. Background Art
[0002] A large number of pipelines are needed for crude oil extraction and transportation. The inner surface of ordinary pipelines is prone to rust. In order to improve the cleanliness of the inner surface, the pipeline is generally sandblasted by a sandblasting device. The working principle of the sandblasting device is to use compressed air as the power to spray abrasives such as shot peening, steel sand, iron sand, etc. at high speed onto the inner surface of the pipeline to be processed, and the abrasive impacts the inner surface of the pipeline to improve the mechanical properties of the inner surface of the pipeline.
[0003] However, when the abrasive impacts the inner surface of the pipe, some of the abrasive will overflow from the end of the pipe, causing pollution to the external environment. Utility Model Content
[0004] The present application aims to at least solve the technical problem in the prior art that part of the abrasive overflows from the end of the pipeline and pollutes the external environment. To this end, the present application proposes a dust prevention device for pipeline cleaning.
[0005] In a first aspect, the present application provides a dust-proof device for pipeline cleaning, comprising: a housing and a dust cover;
[0006] The shell is provided with a leakage cavity, and the dust cover is rotatably mounted on the shell and has an open state and a closed state;
[0007] Wherein, when the dust cover is in the open state, the dust cover is at least partially separated from the outer shell, and the leakage cavity of the outer shell is used for one end of the pipeline to extend into; when the dust cover is in the closed state, the dust cover is covered on the pipeline and closes the leakage cavity of the outer shell.
[0008] By adopting the above technical solution, when the sandblasting device sprays abrasives to impact the inner surface of the pipe, the abrasives will enter the leakage cavity of the shell and will not diffuse into the external environment, thereby achieving the purpose of protecting the external environment.
[0009] According to an embodiment of the present application, the outer shell is provided with assembling tubes whose number is the same as the number of the pipelines, and one end of the assembling tube extends into the leakage cavity and faces the end of the pipeline.
[0010] By adopting the above technical solution, it should be noted that the sandblasting device has a nozzle, which enters from the assembly pipe on the outer shell and is then inserted into the pipeline. The nozzle of the sandblasting device sprays abrasive to process the inner surface of the pipeline.
[0011] By providing an assembling pipe, and the assembling pipe is directly opposite to the end of the pipeline, the nozzle of the sandblasting device can be easily inserted, thereby ensuring the accuracy and effectiveness of spraying abrasives.
[0012] According to an embodiment of the present application, the diameter of the assembling pipe at one end close to the pipeline increases toward the pipeline, and the inner wall surface of the assembling pipe conflicts with the end surface of the pipeline.
[0013] By adopting the above technical solution, the diameter of the assembled pipe is increased toward the pipeline, and the inner wall surface is in contact with the end surface of the pipeline. On the one hand, it can be ensured that the nozzle of the sandblasting device can be more easily inserted into the pipeline without being hindered. On the other hand, the abrasive sprayed by the nozzle may leak out from between the pipeline and the assembled pipe. This design can enhance the sealing and prevent the abrasive from leaking from between the pipeline and the assembled pipe into the external environment.
[0014] According to one embodiment of the present application, a feeding mechanism is provided in the outer shell, and a feeding end of the feeding mechanism is fixedly connected to the assembling tube so as to be suitable for moving the assembling tube toward the end of the pipeline.
[0015] By adopting the above technical solution, after one end of the pipe is inserted from the assembled pipe into the leakage cavity of the outer shell, the assembled pipe can be driven to move toward the end of the pipe by the feed end of the feed mechanism to ensure that the inner wall surface of the assembled pipe contacts the end surface of the pipe, thereby further enhancing the sealing and preventing abrasives from leaking from between the pipe and the assembled pipe into the external environment.
[0016] According to an embodiment of the present application, a moving mechanism is fixedly connected to the bottom of the shell, and the moving mechanism is suitable for allowing one end of the pipe to extend into the leakage cavity of the shell.
[0017] By adopting the above technical solution, the operator can easily insert one end of the pipe from the assembly pipe into the leakage cavity of the shell through the moving mechanism without excessive manpower or tools. This can simplify the operation process and improve the convenience and efficiency of the operation.
[0018] According to an embodiment of the present application, a rotating adjustment frame is provided on the moving mechanism, and the rotating adjustment frame is used to place at least one pipeline and drive the pipeline to rotate along the central axis of the pipeline.
[0019] By adopting the above technical solution, in actual implementation, at least two rotatable rotating wheels are installed on the rotating adjustment frame, and the pipe is supported between the two rotating wheels. When the two rotating wheels rotate clockwise or counterclockwise, the pipe can be driven to rotate.
[0020] By using a rotating adjustment frame, the pipe can be rotated along its central axis during the blasting process, which ensures that every part of the inner wall of the pipe is evenly sprayed with abrasive.
[0021] The number of the rotating adjustment frames can be multiple, and the multiple rotating adjustment frames can be arranged side by side and support the pipeline at the same time.
[0022] According to an embodiment of the present application, the leakage cavity of the shell is provided with a leakage hole, the leakage cavity of the shell passes through the moving mechanism, and the leakage hole is located below the moving mechanism.
[0023] By adopting the above technical solution, the leakage hole can be used to discharge the abrasive and impurities entering the leakage cavity of the shell, so as to keep the inside of the shell clean and prevent the abrasive and impurities from accumulating and affecting the normal operation of the device.
[0024] According to one embodiment of the present application, at least one first notch is formed on the outer shell, and a second notch corresponding to the first notch is formed on the dust cover; when the dust cover is arranged on the pipe, the pipe is arranged between the first notch and the second notch.
[0025] By adopting the above technical solution, the corresponding relationship between the first notch and the second notch can ensure that the dust cover is stably positioned on the pipeline, and can prevent the pipeline from being offset or misaligned during the cleaning process. The alignment and limiting of the first notch and the second notch can ensure that the impact effect of the sandblasting device on the inner surface of the pipeline is uniform, thereby improving the efficiency and quality of the cleaning operation.
[0026] According to an embodiment of the present application, dustproof sheets are installed on the inner wall surfaces of the first notch and the second notch, and the outer wall surface of the pipe abuts against the dustproof sheets.
[0027] By adopting the above technical solution, the dustproof sheet can prevent the abrasive inside the pipeline from overflowing into the external environment, thereby protecting the cleanliness and safety of the workplace.
[0028] In addition, the dustproof sheet serves as a buffer material between the pipe and the shell, which can reduce the friction and wear when the pipe contacts the shell.
[0029] According to one embodiment of the present application, it includes: a first dustproof device and a second dustproof device;
[0030] The first dustproof device and the second dustproof device each include a housing and a dust cover;
[0031] One end of the pipeline extends into the leakage cavity of the shell of the first dustproof device, and the other end of the pipeline extends into the leakage cavity of the shell of the second dustproof device.
[0032] By adopting the above technical solution, the two ends of the pipeline are respectively overlapped in the leakage cavity of the housing of the first dustproof device and the second dustproof device, and the pipeline can be additionally supported to prevent the pipeline from shaking or shifting during operation. This helps to ensure the safety and accuracy of the sandblasting or cleaning operation.
[0033] The overlapped part of the pipe end and the first dustproof device and the second dustproof device is in the leakage cavity of the corresponding housing, which can reduce the overflow or leakage of abrasive during sandblasting or cleaning, effectively prevent the abrasive from overflowing into the surrounding environment, and keep the workplace clean and safe.

[0042] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.
[0043] First, in order to facilitate the description of the relative position relationship and setting points of each mechanism in this application, the implementation scenario of the embodiment of this application is explained here.
[0044] A large number of pipelines are needed for crude oil extraction and transportation. The inner surface of ordinary pipelines is prone to rust. In order to improve the cleanliness of the inner surface, the pipeline is generally sandblasted by a sandblasting device. The working principle of the sandblasting device is to use compressed air as the power to spray abrasives such as shot peening, steel sand, iron sand, etc. at high speed onto the inner surface of the pipeline to be processed, and the abrasive impacts the inner surface of the pipeline to improve the mechanical properties of the inner surface of the pipeline.
[0045] However, when the abrasive impacts the inner surface of the pipe, some of the abrasive will overflow from the end of the pipe, causing pollution to the external environment.
[0046] Reference below Figure 1-Figure 5 A dust prevention device for pipeline cleaning according to an embodiment of the present application is described.
[0047] like Figure 1 and Figure 2 As shown, the dustproof device for pipeline cleaning includes: a shell 100 and a dustproof cover 200.
[0048] The housing 100 is provided with a leakage cavity 110 , and the dust cover 200 is rotatably mounted on the housing 100 and has an open state and a closed state.
[0049] Among them, when the dust cover 200 is in the open state, the dust cover 200 is at least partially separated from the outer shell 100, and the leakage cavity 110 of the outer shell 100 is used for one end of the pipe a to extend into; when the dust cover 200 is in the closed state, the dust cover 200 covers the pipe a and closes the leakage cavity 110 of the outer shell 100.
[0050] In actual use, the dust cover 200 can be first placed in an open state. In this state, the pipe a can be hoisted from top to bottom and placed on the outer shell 100, and the end of the pipe a is placed in the leakage cavity 110, or at least partially placed directly above the leakage cavity 110; then the dust cover 200 is covered on the pipe a, and the dust cover 200 is now in a closed state, and the dust cover 200 seals the leakage cavity 110 of the outer shell 100.
[0051] In this embodiment, when the sandblasting device sprays abrasives to impact the inner surface of the pipe a, the abrasives will enter the leakage cavity 110 of the housing 100 and will not diffuse into the external environment, thereby achieving the purpose of protecting the external environment.
[0052] like Figure 1 and Figure 2 As shown, in some embodiments, the housing 100 is provided with assembling tubes 120 whose number is the same as the number of the pipes a, and one end of the assembling tube 120 extends into the leakage cavity 110 and faces the end of the pipe a.
[0053] It should be noted that the sandblasting device has a nozzle, which enters from the assembly pipe 120 on the housing 100 and is then inserted into the pipe a. The nozzle of the sandblasting device sprays abrasive to process the inner surface of the pipe a.
[0054] In this embodiment, by providing the assembling tube 120, and the assembling tube 120 is directly opposite to the end of the pipeline a, the nozzle of the sandblasting device can be easily inserted, thereby ensuring the accuracy and effectiveness of the abrasive spraying.
[0055] like Figure 2 and Figure 3 As shown, in some embodiments, the diameter of the assembling tube 120 at one end close to the pipe a increases toward the pipe a, and the inner wall surface of the assembling tube 120 conflicts with the end surface of the pipe a.
[0056] In this embodiment, by increasing the diameter of the assembled tube 120 toward the pipe a and making the inner wall surface contact the end surface of the pipe a, on the one hand, it can be ensured that the nozzle of the sandblasting device can be more easily inserted into the pipe a without being hindered. On the other hand, the abrasive sprayed by the nozzle may leak out from between the pipe a and the assembled tube 120. This design can enhance the sealing performance and prevent the abrasive from leaking from between the pipe a and the assembled tube 120 into the external environment.
[0057] like Figure 2 and Figure 4 As shown, in some embodiments, a moving mechanism 320 is fixedly connected to the bottom of the housing 100 , and the moving mechanism 320 is suitable for allowing one end of the pipe a to extend into the leakage cavity 110 of the housing 100 .
[0058] In this embodiment, the operator can easily insert one end of the pipe a from the assembly pipe 120 into the leakage cavity 110 of the housing 100 through the moving mechanism 320 without excessive manpower or tools. This can simplify the operation process and improve the convenience and efficiency of the operation.
[0059] like Figure 3As shown, in some embodiments, a feeding mechanism 310 is disposed in the housing 100, and a feeding end of the feeding mechanism 310 is fixedly connected to the assembling tube 120, so as to be suitable for moving the assembling tube 120 toward the end of the pipeline a.
[0060] In this embodiment, after one end of pipe a is inserted from the assembling tube 120 into the leakage cavity 110 of the outer shell 100, the assembling tube 120 can be driven by the feeding end of the feeding mechanism 310 to move toward the end of pipe a to ensure that the inner wall surface of the assembling tube 120 contacts the end surface of the pipe a, thereby further enhancing the sealing and preventing abrasives from leaking from between the pipe a and the assembling tube 120 into the external environment.
[0061] In actual implementation, the feeding mechanism 310 includes but is not limited to a cylinder.
[0062] like Figure 2 As shown, in some embodiments, a rotating adjustment frame 330 is provided on the moving mechanism 320, and the rotating adjustment frame 330 is used to place at least one pipe a and drive the pipe a to rotate along the central axis of the pipe a.
[0063] In actual implementation, at least two rotatable rotating wheels 331 are installed on the rotating adjustment frame 330 , and the two rotating wheels 331 are used to carry the pipe a, and when the two rotating wheels 331 rotate clockwise or counterclockwise, the pipe a can be driven to rotate.
[0064] By using the rotating adjustment frame 330, the pipe a can be rotated along its central axis during the sandblasting process, which can ensure that every part of the inner wall of the pipe a can be sprayed with abrasive evenly.
[0065] The number of the rotating adjustment frame 330 can be multiple, and the multiple rotating adjustment frames 330 can be arranged side by side and support the pipeline a at the same time.
[0066] like Figure 4 As shown, in some embodiments, the leakage cavity 110 of the housing 100 is provided with a leakage hole 111 , the leakage cavity 110 of the housing 100 penetrates the moving mechanism 320 , and the leakage hole 111 is located below the moving mechanism 320 .
[0067] In this embodiment, the leakage hole 111 can be used to discharge abrasives and impurities entering the leakage cavity 110 of the housing 100, so as to keep the interior of the housing 100 clean and prevent abrasives and impurities from accumulating and affecting the normal operation of the device.
[0068] like Figure 3As shown, in some embodiments, at least one first notch 410 is provided on the housing 100, and a second notch 420 corresponding to the first notch 410 is provided on the dust cover 200; when the dust cover 200 is covered on the pipe a, the pipe a is provided between the first notch 410 and the second notch 420.
[0069] In this embodiment, the corresponding relationship between the first notch 410 and the second notch 420 can ensure that the dust cover 200 is stably positioned on the pipe a, and can prevent the pipe a from being offset or misaligned during the cleaning process. The alignment and limiting of the first notch 410 and the second notch 420 can ensure that the impact effect of the sandblasting device on the inner surface of the pipe a is uniform, thereby improving the efficiency and quality of the cleaning operation.
[0070] like Figure 3 As shown, in some embodiments, dust-proof sheets 430 are installed on the inner wall surfaces of the first notch 410 and the second notch 420 , and the outer wall surface of the pipe a abuts against the dust-proof sheets 430 .
[0071] In this embodiment, the dustproof sheet 430 can prevent the abrasive inside the pipe a from overflowing into the external environment, thereby protecting the cleanliness and safety of the workplace.
[0072] In addition, the dustproof sheet 430 serves as a buffer material between the pipe a and the housing 100, which can reduce the friction and wear when the pipe a contacts the housing 100.
[0073] like Figure 5 As shown, in some embodiments, the dust prevention device for pipeline cleaning includes: a first dust prevention device 10 and a second dust prevention device 20.
[0074] The first dustproof device 10 and the second dustproof device 20 each include a housing 100 and a dustproof cover 200;
[0075] One end of the pipe a extends into the leakage cavity 110 of the housing 100 of the first dustproof device 10 , and the other end of the pipe a extends into the leakage cavity 110 of the housing 100 of the second dustproof device 20 .
[0076] In this embodiment, the two ends of the pipe a are respectively overlapped in the leakage cavity 110 of the housing 100 of the first dustproof device 10 and the second dustproof device 20, and the pipe a can be additionally supported to prevent the pipe a from shaking or shifting during operation. This helps to ensure the safety and accuracy of the sandblasting or cleaning operation.
[0077] The overlapped part between the end of the pipe a and the first dustproof device 10 and the second dustproof device 20 is in the leakage cavity 110 of the corresponding housing 100, so that the overflow or leakage of abrasive during sandblasting or cleaning can be reduced. The abrasive can be effectively prevented from overflowing into the surrounding environment, keeping the workplace clean and safe.
[0078] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
