[0037] Figure 1 The structural schematic diagram of the pipeline cleaning device 10 provided in the present embodiment is shown in Figure 1The embodiment provides a pipeline cleaning device 10, which is used for cleaning an 8mm instrument pipeline in the embodiment, and can be used for cleaning other small-diameter pipelines, such as other gas source pipelines 20, and the like. It should be noted that the small-diameter pipeline in the embodiment can be regarded as a pipeline with a diameter less than or equal to 50mm.

[0038] The pipeline cleaning device 10 comprises a ball loading pipe 100, a communication pipe 200, a pushing structure 300 and a ball launching structure 400. The ball loading pipe 100 is used for loading a plurality of cleaning balls 700, and is in communication with a middle part of the communication pipe 200. An elastic element 111 arranged in the ball loading pipe 100 is used for sending a cleaning ball 700 into the communication pipe 200. The pushing structure 300 is arranged at one end of the communication pipe 200, and the ball launching structure 400 is in communication with the other end of the communication pipe 200. The pushing structure 300 is used for pushing the cleaning ball 700 in the ball loading pipe 100 into the ball launching structure 400, and the ball launching structure 400 is used for connecting with the pipeline 20 to be cleaned and sending the cleaning ball 700 into the pipeline 20, so that the pipeline 20 is cleaned through the movement of the cleaning ball 700 in the pipeline 20.

[0039] Specifically, the ball loading pipe 100 is a tubular structure with one end closed and one end open, and an inner hole for loading the cleaning balls 700 is formed in the ball loading pipe 100. The closed end of the ball loading pipe 100 is provided with the elastic element 111, which is in a compressed state under the extrusion of the cleaning ball 700, so that the elastic element 111 applies a pushing force to the cleaning ball 700 towards the open end of the ball loading pipe 100. The open end of the ball loading pipe 100 is connected with the middle part of the communication pipe 200, so that the inner hole is in communication with the communication pipe 200, and thus the cleaning ball 700 in the ball loading pipe 100 naturally enters the communication pipe 200 under the elastic force of the elastic element 111. Meanwhile, the inner diameter of the ball loading pipe 100 can be greater than the radial dimension of the cleaning ball 700 and less than twice the radial dimension of the cleaning ball 700, and the inner diameter of the communication pipe 200 is also greater than the radial dimension of the cleaning ball 700 and less than twice the radial dimension of the cleaning ball 700, so that only one cleaning ball 700 is ensured to be in the communication pipe 200 at a time. The radial dimension of the cleaning ball 700 can be set according to the inner diameter of the pipeline 20 to be cleaned, and in the embodiment, the cleaning ball 700 can pass through the pipeline 20 and meet the cleaning requirement of the pipeline 20. For example, the cleaning ball 700 can be a sphere with a radial dimension of 7mm in the embodiment.

[0040] Optionally, in order to realize the loading of the cleaning ball 700 in the ball loading tube 100, the ball loading tube 100 can be arranged to be detachably connected with the communication tube 200. Optionally, the communication tube 200 and the ball launching structure 400 can also be arranged to be detachably connected. Optionally, the elastic member 111 comprises a spring and a ball pushing block 112, one end of the spring is connected with the bottom of the ball loading tube 100, and the other end is connected with the ball pushing block 112, so that the ball pushing block 112 is pushed to slide in the ball loading tube 100 by the spring, forming a piston structure, and the cleaning ball 700 is pushed to load into the communication tube 200 by the sliding of the ball pushing block 112 in the ball loading tube 100 towards the communication tube 200.

[0041] Further, the communication tube 200 is also provided with a positioning portion 211, the fifth interior 211 is opposite to the communication position of the communication tube 200 and the ball loading tube 100, so that when the cleaning ball 700 is pushed out of the ball loading tube 100 and abuts against the positioning portion 211, the positioning portion 211 positions the cleaning ball 700 in the standby position, avoiding the deviation of the position of the cleaning ball 700 before the cleaning ball 700 is pushed by the pushing structure 300.

[0042] Optionally, the positioning portion 211 is a protruding portion formed by the inner wall of the communication tube 200 protruding, by arranging the protruding portion, the size of the communication tube 200 is reduced, specifically, the size of the communication tube 200 after being reduced at the protruding portion can be arranged to be slightly smaller than the cleaning ball 700, for example, the difference between the size and the diameter of the cleaning ball 700 is arranged to be less than 1 mm. When the cleaning ball 700 is pushed into the communication tube 200 along the axial direction of the ball loading tube 100 and the radial direction of the communication tube 200, the cleaning ball 700 is stuck at the protruding portion, at this time, the cleaning ball 700 is in the standby position, when the cleaning ball 700 is subjected to the axial pushing force of the pushing structure 300 along the communication tube 200, the cleaning ball 700 overcomes the sticking force generated by the protruding portion, and then moves to the ball launching structure 400 by overcoming the protruding portion. At the same time, when the cleaning ball 700 in the standby position is pushed to the ball launching structure 400, the cleaning ball 700 in the ball loading tube 100 is pushed out of the ball loading tube 100 by the elastic member 111 and is in the standby position. It should be noted that in other embodiments, the structure of the positioning portion 211 can also be specifically arranged, for example, the positioning portion 211 is arranged as a recessed portion formed by the inner wall of the communication tube 200 being recessed, when the cleaning ball 700 is pushed out of the ball loading tube 100 by the elastic member 111, the cleaning ball 700 is positioned by being engaged with the recessed portion.

[0043] In the embodiment, the pipeline cleaning device 10 further comprises a control gas circuit 500, the pushing structure 300 comprises a control cylinder 310, the control gas circuit 500 has a first gas circuit 512 in communication with the control cylinder 310, and the control cylinder 310 is controlled by charging and discharging through the first gas circuit 512, so as to realize the control of the control cylinder 310. The controller has a first piston part 320 in sliding fit with the communication pipe 200, and the control cylinder 310 drives the first piston part 320 to move in the communication pipe 200 under the control of the first gas circuit 512, so as to push the cleaning ball 700 into the ball launching structure 400.

[0044] Specifically, the control cylinder 310 comprises a cylinder body 311 and a piston part arranged in the cylinder body 311, which is a second piston part 312. The second piston part 312 is in sliding fit with the cylinder body 311, and two relatively closed chambers are formed in the cylinder body 311 through the second piston part 312, one of which is a control chamber 313 in communication with the first gas circuit 512. The second piston part 312 is fixedly connected with the first piston part 320 through a connecting rod, one end of the connecting rod is connected to a side of the second piston part 312 away from the control chamber 313, and the other end of the connecting rod extends out of the cylinder body 311 and is fixedly connected with the first piston part 320. In this way, when the second piston part 312 moves towards the first piston part 320 under the action of the gas pressure in the control chamber 313, the first piston part 320 moves into the communication pipe 200, until the first piston part 320 contacts the cleaning ball 700 and pushes the cleaning ball 700 away from the standby position. Optionally, a spring is arranged in the control chamber 313, which is used to pull the second piston part 312 back to the original position when the gas pressure in the control chamber 313 decreases. Optionally, the control cylinder 310 can adopt a model of CJ1B-4X15-S-U4, single action.

[0045] Optionally, the control gas circuit 500 further comprises a two-position three-way valve 511, the first gas circuit 512 is connected with the two-position three-way valve 511, and the two-position three-way valve 511 further has a compressed air inlet and an exhaust port. The two-position three-way valve 511 controls the opening and closing of the first gas circuit 512, the compressed air inlet and the exhaust port. Specifically, when the first gas circuit 512 is in communication with the compressed air inlet under the control of the two-position three-way valve 511, the compressed air enters the control chamber 313 through the first gas circuit 512, so as to drive the first piston part 320 to move the cleaning ball 700 towards the ball launching structure 400; when the first gas circuit 512 is in communication with the exhaust port under the control of the two-position three-way valve 511, the compressed air in the control chamber 313 is exhausted, the gas pressure decreases, and the second piston part 312 drives the first piston part 320 to reset. Optionally, the two-position three-way valve 511 can adopt a model of 4R310-1010, manual straight through. In the embodiment, the pressure of the compressed air is 0.8 Mpa.

[0046] Further, the control air path 500 further comprises a second air path 513, the second air path 513 is used to communicate with the ball launching structure 400, and compressed air is delivered to the ball launching structure 400 through the second air path 513, so as to blow the cleaning ball 700 into the pipeline 20 under the air pressure. Specifically, in the embodiment, the second air path 513 is connected to the first air path 512, and the communication with the two-position three-way valve 511 is realized through the first air path 512. It can be understood that, in other embodiments, the second air path 513 can also be directly connected to the two-position three-way valve 511, that is, the second air path 513 is connected to the first air path 512 at the same joint of the two-position three-way valve 511.

[0047] Optionally, the ball launching structure 400 has a pressurized blowing pipe 410, the pressurized blowing pipe 410 has opposite first and second ends 411 and 412, the first end 411 of the pressurized blowing pipe 410 communicates with the second air path 513 through the pressure regulating valve 421, and the second end 412 of the pressurized blowing pipe 410 is used to communicate with the pipeline 20. The communication pipe 200 communicates with the pressurized blowing pipe 410, and the communication position of the communication pipe 200 with the pressurized blowing pipe 410 is located between the first and second ends 411 and 412. In this way, the cleaning ball 700 entering the pressurized blowing pipe 410 from the communication pipe 200 is located in the middle part of the pressurized blowing pipe 410. The cleaning ball 700 is blown by the compressed air flowing from the first end 411 to the second end 412 of the pressurized blowing pipe 410, and moves towards the pipeline 20 along with the compressed air, so as to realize the cleaning of the pipeline 20. The pressure regulating valve 421 arranged at the first end 411 can regulate the pressure of the compressed air entering the pressurized blowing pipe 410, so as to adjust the air pressure according to the cleaning effect, so as to avoid the occurrence of ball blocking and the like, and ensure the cleaning effect.

[0048] Optionally, the pressure regulating valve 421 can adopt a model number: AW3000. Optionally, the second end 412 of the pressurized blowing pipe 410 is provided with a quick connector, which is a first quick connector 413, and the first quick connector 413 is connected with the pipeline 20, so as to facilitate disassembly and assembly.

[0049] Further, the ball launching structure 400 further comprises a pressure gauge 422, the pressure gauge 422 is used to detect the air pressure in the pressurized blowing pipe 410, and the cleaning effect is judged by the air pressure in the pressurized blowing pipe 410. For example, if it is detected that the air pressure in the blowing pipe fluctuates greatly, it may be that the ball is blocked, and the pressure of the compressed air entering the pressurized blowing pipe 410 can be increased. Optionally, the pressure gauge 422 can adopt a model number: Y-60.

[0050] Figure 2 A partial structure schematic diagram of the pipeline cleaning device 10 provided by the embodiment is shown. Please refer to Figure 1 and Figure 2In the embodiment, the second gas path 513 is further provided with a switching valve 514, which is arranged on the control cylinder 310 and is used to collide with the switching valve 514 when the first piston part 320 pushes the cleaning ball 700 to move to the communicating pipe 200, so as to open the second gas path 513.

[0051] Specifically, the switching valve 514 is arranged on the cylinder body 311 (as shown in the figure, the switching valve 514 is drawn out from the installation position along the dotted line for the convenience of illustration), when the second piston part 312 drives the first piston part 320 to move to the preparation position of the cleaning ball 700 and pushes the cleaning ball 700 out of the preparation position, the second piston part 312 moves to the switching valve 514 and collides with the switching valve 514, so as to open the second gas path 513. Figure 2 Figure 1 After the second gas path 513 is opened, the compressed air enters the pressurized purge pipe 410 from the second gas path 513, so as to blow the cleaning ball 700 in the pressurized purge pipe 410 into the pipeline 20 to be cleaned and purge the pipeline 20. After the cleaning ball 700 is blown out of the pipeline 20, the two-position three-way valve 511 can be operated, so that the air pressure in the control cavity 313 is reduced, the first piston part 320 is reset under the driving of the second piston part 312, the second piston part 312 is separated from the switching valve 514, and the switching valve 514 is reset at the same time, and the second gas path 513 is closed.

[0052] Optionally, the switching valve 514 can be a striker switching valve, and the model thereof can be BD535.

[0053] Please refer to the figure again Figure 1 In the embodiment, the pipeline cleaning device 10 further comprises a ball collecting structure 600, which is connected to one end of the pipeline 20 away from the ball launching structure 400, so as to collect the cleaning ball 700 which has finished cleaning the pipeline 20.

[0054] ​Optionally, the ball collecting structure 600 comprises a quick connector, which is the second quick connector 611, and a mesh bag 612, the ball collecting structure 600 is connected with the pipeline 20 through the second quick connector 611, the cleaning head is away from the pipeline 20 from the end of the pipeline 20 far away from the ball launching connector after cleaning the pipeline 20, then passes through the second quick connector 611 and falls into the mesh bag 612, the mesh bag 612 traps the cleaning ball 700, and the cleaning ball 700 is recycled. Since the cleaning ball 700 moves relative to the pipeline 20 under the action of the air pressure of the compressed air in the embodiment, the mesh bag 612 arranged at the end of the pipeline 20 can meet the discharge requirement of the compressed air, on the other hand, the mesh size of the mesh bag 612 should be smaller than the aperture of the cleaning ball 700, so as to trap the cleaning ball 700 and recycle the cleaning ball 700. After the cleaning ball 700 is recycled, it can be used again after being cleaned.

[0055] Figure 3 The pipeline cleaning method provided in the embodiment is provided with a step diagram. Please refer to Figure 3 The embodiment of the present application also provides a pipeline cleaning method, which can be realized by the pipeline cleaning device 10 described above. Specifically, the pipeline cleaning method comprises the following steps:

[0056] S01: connecting the ball launching structure 400 with the pipeline 20 to be cleaned.

[0057] The first quick connector 413 is connected with one end of the pipeline 20, and since the pipeline cleaning device 10 provided above also has the ball collecting structure 600, the ball collecting connector also needs to be connected with the other end of the pipeline 20, specifically, the second quick connector 611 is connected with the other end of the pipeline 20.

[0058] S02: pushing the cleaning ball 700 in the communication pipe 200 into the ball launching structure 400 by the pushing structure 300, and sending the cleaning ball 700 to the pipeline 20 through the ball launching structure 400.

[0059] The two-position three-way valve 511 is controlled to connect the compressed air with the first air path 512, the air pressure in the control chamber 313 is increased, the second piston part 312 is driven to move against the spring force, thereby driving the first piston part 320 to move relative to the communication pipe 200 to the preparation position of the cleaning ball 700, until the first piston part 320 drives the cleaning ball 700 to leave the preparation position, at the same time that the first piston part 320 drives the cleaning ball 700 to leave the preparation position, the second piston part 312 moves to the switching valve 514 and collides with the switching valve 514 to open the second air path 513, the compressed air enters the pressurized blowing pipe 410 through the second air path 513 and the pressure regulating valve 421, and flows to the second end 412 of the pressurized blowing pipe 410, in the process of flowing, the cleaning ball 700 pushed into the pressurized blowing pipe 410 by the first piston part 320 enters the pipeline 20, and the pipeline 20 is cleaned by the cleaning ball 700 and compressed air blowing. Figure 1 The middle dashed circle shows the approximate path of the cleaning ball 700 moving from the preparation position to the ball collecting structure 600.

[0060] Meanwhile, it should be noted that before step S02 is performed, it is necessary to ensure that there are enough cleaning balls 700 in the ball loading pipe 100, and before step S02 is performed, a step of loading cleaning balls 700 can also be included, and the execution sequence of the step of loading cleaning balls 700 is not limited by step S01, that is, the cleaning balls 700 can be loaded before step S01 is performed, or the cleaning balls 700 can be loaded after step S02 is performed. The step of loading cleaning balls 700 can specifically include: pressing a plurality of cleaning balls 700 into the ball loading pipe 100 through the open end of the ball loading pipe 100.

[0061] S03: According to the pollution condition of the cleaning ball 700 leaving the pipeline 20 from the end of the pipeline 20 away from the ball launching structure 400, it is judged whether the target effect is achieved.

[0062] The cleaning ball 700 moves from one end of the pipeline 20 to the other end under the action of the air pressure of the compressed air, and falls into the ball collecting structure 600 after leaving the pipeline 20, and whether the cleaning of the pipeline 20 achieves the target effect is judged according to the pollution condition of the cleaning ball 700 received in the ball collecting structure 600. For example, it can be set according to the demand that when the cleaning ball 700 received in the ball collecting structure 600 has no pollution condition, it is judged that the target effect is achieved.

[0063] Meanwhile, after the ball launching structure 400 receives the cleaning ball 700, the two-position three-way valve 511 can be operated to disconnect the compressed air from the first air path 512, so as to reset the control cylinder 310 and the switching valve 514.

[0064] S04: If the pigging effect does not reach the target effect, the cleaning ball 700 is sent to the pipeline 20 again through the pipeline cleaning device 10 until the pigging effect reaches the target effect.

[0065] If the cleaning effect on the pipeline 20 does not reach the target effect, the above steps S02 and S03 can be repeated until the pigging effect reaches the target effect.

[0066] The embodiments of the present application provide a pipeline cleaning device 10 and a pipeline cleaning method, which can achieve repeated cleaning of the pipeline 20 by loading the cleaning ball 700 once, reduce the cleaning difficulty and the cleaning workload, and adopt the combination of air blowing and ball passing blowing, which is helpful to improve the cleaning effect and the cleaning efficiency. Meanwhile, the steps of loading the cleaning ball 700 into the ball launching structure 400 and the steps of sending the cleaning ball 700 from the ball launching structure 400 to the pipeline 20 can be simultaneously achieved by one operation, which ensures the synchronization of air blowing and ball passing blowing.

[0067] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
