Description

Technical Field

[0001] This invention relates to the field of lithium battery technology, and in particular to an automatic cleaning method and system for lithium battery slurry. Background Technology

[0002] In current industrial applications, the replacement of pipeline pigging equipment typically employs a traditional manual process of picking up and placing the pigs. This manual intervention method has significant limitations. Firstly, only one pig can be replaced at a time, severely restricting work efficiency. Secondly, the cleaning process also relies on manual labor, consuming substantial manpower and significantly extending the overall cleaning cycle due to its cumbersome and time-consuming nature. This directly leads to low pipeline cleaning efficiency and negatively impacts equipment lifespan. Furthermore, frequent manual intervention makes human error unavoidable, further reducing operational stability and reliability.

[0003] Looking at the existing automatic cleaning technologies for lithium battery slurry on the market, their technical bottlenecks are particularly prominent: First, the lack of a leak-free ball loading module means that gas leakage cannot be effectively prevented during the ball pushing and adding process, which not only threatens the health of workers but also pollutes the environment; second, the absence of an automatic ball cleaning module makes it impossible to automate the ball pushing and cleaning process, increasing manual operation costs and time costs; finally, the lack of a leak-free ball collection module means that the risk of gas leakage also exists during the ball pushing and recycling stage, which seriously restricts the overall performance and safety of the automatic cleaning system for lithium battery slurry and makes it difficult to meet the strict requirements of modern industry for efficient, environmentally friendly, and safe operation. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic cleaning method and system for lithium battery slurry to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, the present invention provides an automatic cleaning method for lithium battery slurry, the method comprising: S1. In response to the ball entering the cleaning chamber of the ball cleaning unit, the nozzle is controlled to rinse the ball. After rinsing, the ball is dried with compressed air. The dried ball enters the detection unit through the connecting pipe. S2. In response to the ball entering the detection unit, the two diaphragms of the ball divide the detection chamber into a left chamber, a middle chamber, and a right chamber. By judging the pressure values ​​of the left chamber, the middle chamber, and the right chamber, it is determined whether the ball has passed the detection. S3. If the ball pushing test in step S2 passes, the ball is pushed into the main conveying pipeline for pipeline cleaning using air pressure. After the pipeline cleaning is completed, the ball reaches the reducing pipe of the reverse ball serving unit and is pushed back into the cleaning chamber of the cleaning ball serving unit using air pressure. Steps S1 to S2 are repeated. If the ball pushing test passes again, the ball is pushed back into the cleaning chamber of the cleaning ball serving unit again using air pressure to complete one cleaning task. S4. If the ball pushing detection in step S2 fails, the ball is pushed back into the cleaning chamber of the ball cleaning and serving unit using air pressure, and the ball is controlled to fall into the ball collecting chamber of the ball collecting unit. When the ball collecting chamber is full of balls, the ball collecting process is performed. When the ball collecting chamber is not full of balls, the automatic ball loading process is performed through the clip unit.

[0006] In one possible implementation, in step S1, in response to the ball entering the cleaning chamber of the ball-cleaning unit, the nozzle is controlled to rinse the ball. After rinsing, the ball is dried with compressed air. The dried ball then enters the detection unit via a connecting pipe, including: S11. In response to the ball entering the cleaning chamber of the ball cleaning unit, control the nozzle to rinse the ball. After rinsing, control the first air inlet to open and use compressed air to dry the ball. S12. After the ball is dried, the first ball valve is opened, and the second push rod is driven by the second push rod cylinder to push the ball into the connecting pipe. Compressed air is used to push the ball into the detection unit, and the first ball valve is closed.

[0007] In one possible implementation, in step S2, in response to the ball entering the detection unit, the two diaphragms of the ball divide the detection cavity into a left cavity, a middle cavity, and a right cavity. Determining whether the ball has passed detection by judging the pressure values ​​in the left cavity, middle cavity, and right cavity includes: S21. In response to the ball entering the detection unit, the control limiting component limits the ball, and when the first magnetic proximity switch senses the ball, the second ball valve and the third ball valve are closed, so that the detection pipe section of the detection unit forms a detection cavity between the second ball valve and the third ball valve, and the two diaphragms of the ball divide the detection cavity into a left cavity, a middle cavity and a right cavity. S22. Control the solenoid valve to open, so that the left cavity, middle cavity and right cavity are connected to the outside atmosphere, and close the solenoid valve after ensuring that the initial air pressure inside the left cavity, middle cavity and right cavity is consistent with the external atmospheric pressure. S23. Control the pressure regulating valve to introduce detection air pressure into the intermediate chamber, and the detection air pressure slowly increases from 0. S24. When the pressure value of the left cavity and / or the right cavity is detected to be greater than 0, the pressure value in the intermediate cavity is obtained; S25. When the pressure value in the intermediate cavity is detected to be greater than the preset damage air pressure value, it is determined that the ball pusher is normal and the test is passed; S26. When the pressure value in the intermediate cavity is detected to be less than the preset damage air pressure value, it is determined that the push ball is damaged and the test fails.

[0008] In one possible implementation, in step S3, if the ball-pushing detection in step S2 passes, the ball is pushed into the main delivery pipeline using air pressure for pipeline cleaning. After pipeline cleaning, the ball reaches the reducer of the reverse ball-serving unit and is pushed back into the cleaning chamber of the cleaning ball-serving unit using air pressure. Steps S1 to S2 are repeated. If the ball-pushing detection passes again, the ball is pushed back into the cleaning chamber of the cleaning ball-serving unit again using air pressure, completing one cleaning task, including: S31. If the ball pushing detection in step S2 passes, the limiting component, the second ball valve, and the third ball valve of the detection unit are all in the open state. The first ball valve and the first air inlet of the cleaning ball serving unit are all in the open state. The ball is pushed into the main conveying pipeline by air pressure for pipeline cleaning. The forward cleaning waste liquid flows into the first waste liquid tank of the reverse ball serving unit until the ball reaches the reducing pipe of the reverse ball serving unit. S32. In response to the second magnetic induction proximity switch sensing that the push ball has reached the variable diameter tube, control the first air inlet to stop the air supply, control the sixth ball valve to close, control the fourth ball valve to open to introduce compressed air, and use the air pressure to push the push ball back into the cleaning chamber of the ball-launching unit, while the reverse cleaning waste liquid flows into the second waste liquid tank of the ball-receiving unit. S33. Repeat steps S1 to S2. If the ball pusher passes the test again, use air pressure to push the ball back into the cleaning chamber of the ball cleaning unit to complete one cleaning task.

[0009] In one possible implementation, in step S4, if the ball-pushing detection in step S2 fails, the ball is pushed back into the cleaning chamber of the ball-cleaning unit using air pressure, and the ball is controlled to fall into the ball-collecting chamber of the ball-collecting unit. When the ball-collecting chamber is full of balls, a ball-collecting process is performed. When the ball-collecting chamber is not full of balls, an automatic ball-loading process is performed through the clip unit, including: S41. If the ball push detection in step S2 fails, the ball is pushed back into the cleaning chamber of the ball cleaning unit using air pressure. The ball is located on the V-shaped support formed by the fixed baffle and the movable baffle. S42. Control the first push rod cylinder to drive the first push rod to retract, so that the movable baffle flips under the action of gravity, and the push ball falls into the ball receiving chamber of the ball receiving unit and stays on the filter layer at the bottom of the ball receiving chamber. The filter layer can support the push ball and allow the cleaning waste liquid to flow into the second waste liquid tank below the ball receiving chamber. S43. When the ball receiving chamber is full, a ball receiving process is performed, which includes: S431. Place the recycling bag over the ball outlet at the bottom of the ball collection pipe, manually open the elbow clamp, pull out the sealing push rod, manually reach into the glove, and manually put the damaged push ball in the ball collection chamber into the recycling bag. S432. After recycling is complete, reset the sealing push rod, manually close the elbow clamp, tie the recycling bag, and remove it from the lower ball outlet of the ball collection pipe. S44. When the ball receiving chamber is not full, an automatic ball loading process is performed through the magazine unit. The ball loading process includes: S441. Control the first push rod cylinder to drive the first push rod to extend, so that the movable baffle flips, and the fixed baffle and the movable baffle form a V-shaped support; S442, The cylinder of the control magazine unit drives the stop lever to retract, and the push ball in the buffer compartment falls onto the V-shaped support formed by the movable baffle and the fixed baffle under the action of gravity; S443. Control the stop lever cylinder to drive the stop lever to extend, open the gate valve, and the push ball in the magazine compartment falls into the buffer compartment under the action of gravity; S444. Determine whether there is still a push ball in the magazine. If there is no push ball in the magazine, open the second air inlet to form a slight positive pressure in the upper part of the magazine to prevent the gas in the magazine from overflowing. Open the magazine, put a new push ball into the magazine, and close the magazine and the second air inlet. S445. If there are still push balls in the magazine, repeat steps S1 to S2. If the push ball detection fails, repeat steps S43 to S44. If the push ball detection passes, use air pressure to push the push ball back into the cleaning chamber of the ball cleaning unit, waiting for the next cleaning task.

[0010] In a second aspect, the present invention provides an automatic cleaning system for lithium battery slurry, comprising a pusher ball, wherein the pusher ball includes a column and two diaphragms spaced apart on the column, and the automatic cleaning system for lithium battery slurry further includes: The ball-cleaning unit is used to rinse and dry the push ball, and then launch the dried push ball. A magazine unit, mounted above the ball-cleaning and serving unit, is used to supply the ball-cleaning and serving unit with new push balls; A ball-collecting unit, installed below the ball-cleaning and serving unit, is used to collect damaged push balls; A detection unit, connected to the ball-cleaning and serving unit via a connecting pipe, is used to detect whether the ball is damaged; and The reverse serve unit is connected to the detection unit via the main delivery pipe and is used to send the push ball back to the cleaning serve unit after the main delivery pipe has been cleaned. The ball-cleaning and serving unit includes a cleaning chamber, a first ball valve connected at both ends to the cleaning chamber and the connecting pipe respectively, a nozzle and a first air inlet mounted on the cleaning chamber, a fixed baffle and a movable baffle mounted on the cleaning chamber, a first push rod cylinder mounted on the cleaning chamber, a first push rod driven to the first push rod cylinder and used to push the movable baffle to flip, a second push rod cylinder mounted on the cleaning chamber, and a second push rod driven to the second push rod cylinder and used to push the ball into the connecting pipe.

[0011] In one possible implementation, the magazine unit includes: A buffer chamber, the bottom of which is connected to the top of the cleaning chamber, has a stop lever at its bottom for blocking the pushing of balls. The stop lever is driven by a stop lever cylinder mounted on the buffer chamber. The magazine has an openable top for inserting new push balls and its bottom is connected to the top of the buffer compartment via a gate valve. The magazine compartment has a second air inlet at its upper part and a third exhaust outlet at its lower part.

[0012] In one possible implementation, the ball-collecting unit includes: The ball receiving chamber has its top connected to the bottom of the washing chamber. Its bottom is equipped with a filter layer, and its side walls are fitted with a glove capable of sealing an insertion into the ball receiving chamber, an observation window for observing the contents of the chamber, and a ball receiving pipe for collecting the balls. The second waste liquid tank is installed below the ball receiving chamber, with its top connected to the bottom of the ball receiving chamber, and has a second air outlet at its top and a second liquid drain outlet at its bottom. The ball receiving pipe is inclined downward at one end, which is connected to the ball receiving chamber. The ball receiving pipe has a ball outlet at the middle of its bottom. A sealing push rod is installed inside the ball receiving pipe. A sealing tube is installed at the end of the ball receiving pipe away from the ball receiving chamber. The sealing tube is sleeved on the outer periphery of the push-pull end of the sealing push rod. An elbow clamp is provided at the end of the sealing tube away from the ball receiving pipe.

[0013] In one possible implementation, the detection unit includes: The inspection pipeline section has one end connected to the connecting pipeline via a second ball valve, and the other end connected to the main delivery pipeline via a third ball valve. The detection pipeline section includes a first magnetic proximity switch and a limit assembly installed between the second ball valve and the third ball valve. The detection pipeline section also includes three first pressure sensors, three solenoid valves, a pressure gauge, and a pressure regulating valve installed between the first magnetic proximity switch and the limit assembly.

[0014] In one possible implementation, the reverse serve unit includes: The reverse serve conduit section is connected to the main delivery conduit via a reducing pipe at its top; a second magnetic proximity switch is installed at the reducing pipe. The first waste liquid tank has its top connected to the bottom of the reverse ball launching pipeline section via a sixth ball valve, and its top also has a first air outlet and its bottom has a first liquid drain outlet. The reverse ball-serving pipeline section is equipped with a fourth ball valve for introducing compressed air and a fifth ball valve for backup compressed air introduction. The fourth ball valve is also equipped with a second pressure sensor for monitoring gas pressure.

[0015] The beneficial effects of the technical solution provided by this invention include at least the following: In this technical solution, after the ball is pushed into the cleaning chamber of the cleaning and launching unit, it is rinsed by a nozzle and then dried with compressed air. The dried ball then enters the detection unit through a connecting pipe. Once in the detection unit, two diaphragms divide the detection chamber into left, middle, and right chambers. The pressure values ​​in these three chambers determine whether the ball is qualified. If the ball passes the test, it is pushed into the main delivery pipeline for cleaning using air pressure. After cleaning, the ball reaches the reducer in the reverse launching unit and is pushed back into the cleaning chamber by air pressure. This cleaning and detection process is repeated. If the ball passes the test again, it is pushed back into the cleaning chamber, completing one cleaning cycle. If the ball fails the test, it is pushed back into the cleaning chamber by air pressure and falls into the ball receiving unit's receiving chamber. When the receiving chamber is full, the ball receiving process begins; otherwise, balls are automatically loaded via a clip unit. This system achieves automatic cleaning of the ball, automatic ball loading without leakage, and leak-free ball receiving. It operates in a closed environment, protecting worker health, reducing environmental pollution, and improving pipeline cleaning efficiency. Attached Figure Description

In one example, the filter layer 3.12 includes several evenly spaced rails.

[0040] In this embodiment, the top of the ball receiving chamber 3.1 is connected to the cleaning chamber 2.2 to receive damaged push balls 2.4. The bottom filter layer 3.12 supports the push balls and allows waste liquid to flow into the second waste liquid tank 3.11 below. Its second vent 3.13 and second drain 3.14 can vent and drain liquid. The side glove 3.2 is for sealing and extending during manual operation, and the observation window 3.3 is used to view the situation inside the chamber. The ball receiving pipe 3.4 is inclined. The bottom ball outlet 3.4.1, together with the internal sealing push rod 3.5, the external sealing pipe 3.6 and the elbow clamp 3.7, can achieve sealed ball retrieval by pushing and pulling the sealing push rod and opening and closing the elbow clamp during ball recovery, preventing leakage and ensuring safe recovery of damaged push balls and separation and treatment of waste liquid.

[0041] In another alternative embodiment, see [link to relevant documentation]. Figure 10 The second ball-collecting unit 3 differs from the first ball-collecting unit 3 in that the ball-collecting pipe 3.4, ball outlet 3.4.1, sealing push rod 3.5, sealing tube 3.6, and elbow clamp 3.7 in the first ball-collecting unit 3 are removed and replaced with a ball-collecting opening 3.8, a sealing latch 3.9, and a flap 3.10. That is, the ball-collecting chamber 3.1 has a ball-collecting opening 3.8, and the ball-collecting chamber 3.1 is provided with a flap 3.10 that can be flipped and can seal and cover the ball-collecting opening 3.8. The ball-collecting chamber 3.1 is also equipped with a sealing latch 3.9 for locking the flap 3.10.

[0042] Furthermore, see Figures 11 to 13The detection unit 4 includes a detection pipeline section 4.12, one end of which is connected to the connecting pipeline 6 via a second ball valve 4.1, and the other end of which is connected to the main delivery pipeline 7 via a third ball valve 4.5. A first magnetic induction proximity switch 4.2 and a limiting assembly 4.4 are installed on the detection pipeline section 4.12 between the second ball valve 4.1 and the third ball valve 4.5. Three first pressure sensors 4.3, three solenoid valves 4.6, a pressure gauge 4.7, and a pressure regulating valve 4.8 are installed on the detection pipeline section 4.12 between the first magnetic induction proximity switch 4.2 and the limiting assembly 4.4. In one example, the limiting assembly 4.4 includes a limiting plate for limiting the position of the push ball 2.4 within the detection chamber, and a limiting cylinder for extending or retracting the limiting plate to cancel the limiting. After the ball 2.4 enters the detection unit 4, the control limit component 4.4 limits the ball 2.4. When the first magnetic induction proximity switch 4.2 senses the ball 2.4, it closes the second ball valve 4.1 and the third ball valve 4.5, so that the detection pipe section 4.12 of the detection unit 4 forms a detection cavity between the second ball valve 4.1 and the third ball valve 4.5. The two diaphragms 2.4.2 of the ball 2.4 divide the detection cavity into a left cavity 4.9, a middle cavity 4.10 and a right cavity 4.11. The three first pressure sensors 4.3 and the three solenoid valves 4.6 correspond to the three cavities and work together.

[0043] In this embodiment, the detection pipeline section 4.12 is connected to the connecting pipeline 6 and the main delivery pipeline 7 via the second ball valve 4.1 and the third ball valve 4.5. The first magnetic induction proximity switch 4.2 on the pipeline section can sense the position of the push ball 2.4, and the limiting component 4.4 restricts the position of the push ball in the detection chamber. The three first pressure sensors 4.3 and the three solenoid valves 4.6 correspond to the left chamber 4.9, the middle chamber 4.10, and the right chamber 4.11 separated by the two diaphragms 2.4.2 of the push ball 2.4, and work in conjunction with the pressure gauge 4.7 and the pressure regulating valve 4.8. After the push ball enters, the two ball valves are closed to form the detection chamber. The detection air pressure is introduced into the middle chamber through the pressure regulating valve. The pressure value of the three chambers is used to determine whether the diaphragm is damaged, thereby realizing the damage detection of the push ball 2.4 and ensuring its cleaning function is effective.

[0044] Furthermore, see Figure 14The reverse ball-serving unit 5 includes: a reverse ball-serving pipe section 5.10, the top of which is connected to the main delivery pipe 7 via a reducing pipe 5.1, and a second magnetic induction proximity switch 5.7 is installed at the reducing pipe 5.1; and a first waste liquid tank 5.6, the top of which is connected to the bottom of the reverse ball-serving pipe section 5.10 via a sixth ball valve 5.5, and the top of which also has a first air outlet 5.8, and the bottom of which has a first drain outlet 5.9; wherein, the reverse ball-serving pipe section 5.10 is equipped with a fourth ball valve 5.2 for introducing compressed air and a fifth ball valve 5.4 for backup introducing compressed air, and the fourth ball valve 5.2 is also equipped with a second pressure sensor 5.3 for monitoring gas pressure.

[0045] In this embodiment, the top of the reverse ball-launching pipeline section 5.10 is connected to the main delivery pipeline 7 via a reducer 5.1. A second magnetic proximity switch 5.7 at the reducer 5.1 can detect the arrival position of the ball pusher 2.4. The fourth ball valve 5.2 and the fifth ball valve 5.4 on the reverse ball-launching pipeline section 5.10 are used to introduce compressed air. Together with the second pressure sensor 5.3, they monitor the air pressure, enabling the ball pusher 2.4, after cleaning the main delivery pipeline 7, to be returned to the cleaning and launching unit 2. The first waste liquid tank 5.6 is connected to the bottom of the reverse ball-launching pipeline section 5.10 via a sixth ball valve 5.5. The first air outlet 5.8 and the first drain outlet 5.9 can discharge gas and waste liquid, ensuring that the cleaning waste liquid can be effectively collected and treated during the ball pusher return process.

[0046] It is worth mentioning that all of the above-mentioned air outlets are connected to an external exhaust gas collection tank.

[0047] Figure 1 The diagram illustrates a flow chart of an automatic cleaning method for lithium battery slurry provided in an exemplary embodiment of the present invention. The automatic cleaning method for lithium battery slurry includes: Step S1: In response to the ball entering the cleaning chamber of the ball cleaning unit, the nozzle is controlled to rinse the ball. After rinsing, compressed air is used to dry the ball. The dried ball then enters the detection unit through the connecting pipe.

[0048] Specifically, in step S1, in response to the ball entering the cleaning chamber of the ball-cleaning unit, the nozzle is controlled to rinse the ball. After rinsing, compressed air is used to dry the ball. The dried ball then enters the detection unit through a connecting pipe, including: S11. In response to the ball entering the cleaning chamber of the ball cleaning unit, control the nozzle to rinse the ball. After rinsing, control the first air inlet (corresponding to the first air outlet) to open and use compressed air to dry the ball. S12. After the ball is dried, the first ball valve is opened, and the second push rod cylinder drives the second push rod to push the ball into the connecting pipe. Compressed air is used to push the ball into the detection unit, and the first ball valve is closed.

[0049] In this embodiment, after the ball enters the cleaning chamber of the ball-launching unit, it is first rinsed by a nozzle to remove residual slurry and other impurities from the surface. After rinsing, the first air inlet is opened, and compressed air is used to dry the ball to prevent moisture from affecting subsequent testing. After drying, the first ball valve is opened, and the second push rod cylinder drives the second push rod to push the ball into the connecting pipe. At the same time, the force of the compressed air is used to send the ball into the testing unit. Then, the first ball valve is closed to ensure that the cleaned ball enters the testing stage according to the procedure.

[0050] Step S2: In response to the ball entering the detection unit, the two diaphragms of the ball divide the detection chamber into a left chamber, a middle chamber, and a right chamber. By judging the pressure values ​​of the left chamber, the middle chamber, and the right chamber, it is determined whether the ball has passed the detection.

[0051] Specifically, in step S2, in response to the ball entering the detection unit, the two diaphragms of the ball divide the detection chamber into a left chamber, a middle chamber, and a right chamber. The determination of whether the ball has passed detection is based on the pressure values ​​in the left, middle, and right chambers, including: S21. In response to the ball entering the detection unit, the control limit component limits the ball, and when the first magnetic induction proximity switch senses the ball, the second ball valve and the third ball valve are closed, so that the detection pipeline section of the detection unit forms a detection cavity between the second ball valve and the third ball valve. The two diaphragms of the ball divide the detection cavity into a left cavity, a middle cavity and a right cavity. S22. Control the solenoid valve to open, so that the left chamber, middle chamber and right chamber are connected to the outside atmosphere. After ensuring that the initial air pressure inside the left chamber, middle chamber and right chamber is consistent with the external atmospheric pressure, close the solenoid valve. S23. Control the pressure regulating valve to introduce detection air pressure into the intermediate chamber, and the detection air pressure slowly increases from 0. S24. When the pressure value of the left cavity and / or the right cavity is detected to be greater than 0, the pressure value in the middle cavity is obtained; S25. When the pressure value in the intermediate cavity is detected to be greater than the preset damage air pressure value, it is determined that the ball pushing is normal and the test is passed; S26. When the pressure value detected in the intermediate cavity is less than the preset damage air pressure value, it is determined that the push ball is damaged and the test fails.

[0052] In this embodiment, after the pusher enters the detection unit, its diaphragm divides the cavity into three parts. First, a solenoid valve balances the air pressure in the three chambers with the external environment. Then, a pressure regulating valve slowly pressurizes the middle chamber. When pressure appears in the left / right chambers, the real-time pressure in the middle chamber is read and compared with a preset value. If the pressure is higher than the threshold, it indicates that the diaphragm is well sealed, and the pusher can continue to be used; if it is lower than the threshold, it indicates that the diaphragm is damaged, and the pusher must be discarded. This detection method utilizes the principle of air pressure difference to achieve non-contact, non-destructive testing, which can quickly identify diaphragm damage, ensuring that the cleaning efficiency of the pusher in use meets the standards and avoiding incomplete pipeline cleaning caused by pusher damage.

[0053] Step S3: If the ball pushing test in step S2 passes, use air pressure to push the ball into the main conveying pipeline for pipeline cleaning. After the pipeline cleaning is completed, the ball reaches the reducing pipe of the reverse ball launching unit. Use air pressure to push the ball back into the cleaning chamber of the cleaning ball launching unit. Repeat steps S1 to S2. If the ball pushing test passes again, use air pressure to push the ball back into the cleaning chamber of the cleaning ball launching unit to complete one cleaning task.

[0054] Specifically, in step S3, if the ball-pushing detection in step S2 passes, air pressure is used to push the ball into the main delivery pipeline for pipeline cleaning. After pipeline cleaning is completed, the ball reaches the reducer of the reverse ball-launching unit and is pushed back into the cleaning chamber of the cleaning ball-launching unit using air pressure. Steps S1 to S2 are repeated. If the ball-pushing detection passes again, air pressure is used again to push the ball back into the cleaning chamber of the cleaning ball-launching unit, completing one cleaning task, including: S31. If the ball pushing detection in step S2 passes, the limit component, the second ball valve and the third ball valve of the control detection unit are all in the open state, and the first ball valve and the first air inlet (corresponding to the first air outlet) of the control cleaning ball launching unit are all in the open state. The ball is pushed into the main conveying pipeline by air pressure for pipeline cleaning. The forward cleaning waste liquid flows into the first waste liquid tank of the reverse ball launching unit until the ball reaches the reducing pipe of the reverse ball launching unit. S32. In response to the second magnetic induction proximity switch sensing that the ball pusher has reached the reducer, control the first air inlet to stop the air supply, control the sixth ball valve to close, and control the fourth ball valve to open to allow compressed air (corresponding to the second air outlet). Use the air pressure to push the ball pusher back into the cleaning chamber of the ball launching unit, while the reverse cleaning waste liquid flows into the second waste liquid tank of the ball receiving unit. S33. Repeat steps S1 to S2. If the ball pusher passes the test again, use air pressure to push the ball back into the cleaning chamber of the ball-serving unit to complete one cleaning task.

[0055] In this embodiment, the tested ball is driven by air pressure into the main conveying pipeline. Friction and compression remove slurry from the pipe wall, and the forward cleaning waste flows into the waste tank of the reverse ball launching unit. After reaching the reducer, the ball is reversed by air pressure and flows back to the cleaning chamber, where the reverse waste is collected by the waste tank of the ball receiving unit. The ball undergoes two cleaning and testing cycles during this process. After the first return, repeated rinsing, drying, and pressure testing are performed. Once confirmed to be undamaged, it is returned again, completing the bidirectional cleaning of the pipeline.

[0056] Step S4: If the ball push detection in step S2 fails, use air pressure to push the ball back into the cleaning chamber of the ball cleaning and serving unit, and control the ball to fall into the ball collection chamber of the ball collection unit. When the ball collection chamber is full of balls, the ball collection process is carried out. When the ball collection chamber is not full of balls, the automatic ball loading process is carried out through the clip unit.

[0057] Specifically, in step S4, if the ball-pushing detection in step S2 fails, the ball is pushed back into the cleaning chamber of the ball-cleaning unit using air pressure, and controlled to fall into the ball-collecting chamber of the ball-collecting unit. When the ball-collecting chamber is full, the ball-collecting process is performed. When the ball-collecting chamber is not full, the automatic ball-loading process is performed through the clip unit, including: S41. If the ball-pushing detection in step S2 fails, the ball is pushed back into the cleaning chamber of the ball-serving unit using air pressure (compressed air is introduced through the fourth ball valve, corresponding to the second air outlet). The ball is positioned on the V-shaped support formed by the fixed baffle and the movable baffle (see...). Figure 5 ); S42. Control the first push rod cylinder to drive the first push rod to retract, causing the movable baffle to flip under the action of gravity (see...). Figure 6 The ball is pushed into the ball receiving chamber of the ball receiving unit and rests on the filter layer at the bottom of the ball receiving chamber. The filter layer can support the ball and allow the cleaning waste liquid to flow into the second waste liquid tank below the ball receiving chamber. S43. When the ball receiving chamber is full of push balls, proceed with the ball receiving process: The first ball-collecting process includes: S431. Place the recycling bag over the ball outlet at the bottom of the ball collection pipe, manually open the elbow clamp, pull out the sealing push rod, manually reach into the glove, and manually put the damaged push ball inside the ball collection chamber into the recycling bag. S432. After recycling is complete, reset the sealing push rod, manually close the elbow clamp, tie the recycling bag, and remove it from the ball outlet at the bottom of the ball collection pipe. The second method of receiving the ball includes: S431. When the ball receiving chamber 3.1 is full of push balls 2.4, put a recycling bag on the ball receiving port 3.8, manually reach into the glove 3.2, open the sealing lock 3.9, turn the flap 3.10 downwards, and then manually put the push balls 2.4 into the recycling bag. S432. After recycling, replace the flap 3.10 and close the sealing lock 3.9. Remove the recycling bag. The second ball collection process is simpler in structure and easier to operate than the first ball collection process.

[0058] S44. When the ball receiving chamber is not full, an automatic ball loading process is initiated via the magazine unit. The ball loading process includes: S441. Control the first push rod cylinder to drive the first push rod to extend, so that the movable baffle flips, and the fixed baffle and the movable baffle form a V-shaped support. S442, The cylinder of the magazine unit drives the lever to retract, and the push ball in the buffer compartment falls onto the V-shaped support formed by the movable baffle and the fixed baffle under the action of gravity; S443, The control lever cylinder drives the lever to extend, opening the gate valve, and the push ball in the magazine falls into the buffer compartment under the action of gravity; S444. Determine if there are still push balls in the magazine. If there are no push balls in the magazine, open the second air inlet (corresponding to the third air outlet) to create a slight positive pressure at the top of the magazine to prevent gas from overflowing. Open the magazine, put the new push ball into the magazine, and close the magazine and the second air inlet. S445. If there are still push balls in the magazine, repeat steps S1 to S2. If the push ball detection fails, repeat steps S43 to S44. If the push ball detection passes, use air pressure to push the push ball back into the cleaning chamber of the ball cleaning unit, and wait for the next cleaning task.

[0059] In this embodiment, failed ball pushers are pushed back into the cleaning chamber by air pressure, flipped over by a movable baffle, and fall into the ball collection chamber. The bottom filter layer separates the waste liquid into a second waste liquid tank. When the ball collection chamber is full, it can be recycled in two ways: first, by using a ball collection pipe and sealing push rod to achieve sealed ball retrieval; second, by directly retrieving the ball using a flip plate and sealing latch, the latter being simpler. When the chamber is not full, the magazine unit automatically loads balls, and the baffle cylinder controls the balls to fall from the buffer chamber to the V-shaped support of the cleaning chamber. Balls in the magazine are replenished to the buffer chamber through a gate valve. When balls are insufficient, the magazine is safely opened for replenishment through an air pressure balance design (slight positive pressure). This process achieves automatic sorting and recycling of damaged balls. Combined with the intelligent ball replenishment mechanism of the magazine unit, the production line continues to operate continuously even when balls are worn out, reducing the frequency of manual intervention by 75% and ensuring the automation and reliability of the cleaning system.

[0060] In summary, in this technical solution, after the ball is pushed into the cleaning chamber of the cleaning and launching unit, it is rinsed by the nozzle and then dried with compressed air. The dried ball then enters the detection unit through a connecting pipe. Once in the detection unit, two diaphragms divide the detection chamber into left, middle, and right chambers. The pressure values ​​in these three chambers determine whether the ball is qualified. If the ball passes the test, it is pushed into the main delivery pipeline for cleaning using air pressure. After cleaning, the ball reaches the reducer in the reverse launching unit and is pushed back into the cleaning chamber by air pressure. This cleaning and detection process is repeated. If the ball passes the test again, it is pushed back into the cleaning chamber, completing one cleaning cycle. If the ball fails the test, it is pushed back into the cleaning chamber by air pressure and falls into the ball receiving unit's receiving chamber. When the receiving chamber is full, the ball receiving process begins; otherwise, balls are automatically loaded via the clip unit. This system achieves automatic cleaning of the ball, automatic ball loading without leakage, and leak-free ball receiving. It operates in a closed environment, protecting worker health, reducing environmental pollution, and improving pipeline cleaning efficiency.
