Description

Technical Field

[0001] This application relates to the field of industrial equipment technology for producing conductive paste, and in particular to a pipeline cleaning method and system. Background Technology

[0002] The industrial equipment for producing conductive paste is a large-scale engineering system with a relatively complex piping structure. Specifically, the piping layout of the entire system is complex, with numerous bends and significant changes in the angle of these bends. These factors can hinder the smooth flow of the paste within the pipes, making it prone to accumulation. Furthermore, the paste contains a large number of fine particles or impurities, which can easily deposit and accumulate within the pipes.

[0003] Traditional pipeline cleaning techniques require loading and unloading of cleaning balls for each operation, and existing systems are unidirectional, necessitating personnel to walk from the start to the end of the pipeline to retrieve the balls. This hinders efficient cleaning of the pipeline interior. This is because, firstly, the conductive slurry is a non-Newtonian liquid with viscous, microparticles that requires repeated cleaning in the winding pipeline. Secondly, current cleaning technologies cannot efficiently utilize cleaning wastewater. Therefore, it is necessary to propose a pipeline cleaning method and system to address the low cleaning efficiency of traditional techniques. Summary of the Invention

[0004] Therefore, it is necessary to propose a pipeline cleaning method and system to address the shortcomings of traditional pipeline cleaning technologies, which suffer from low cleaning efficiency.

[0005] This application provides a pipeline cleaning method, including:

[0006] The pressure value of the inner wall of the receiving slurry pipe;

[0007] Determine if the pressure value on the inner wall of the slurry pipeline fluctuates;

[0008] If the pressure value on the inner wall of the slurry pipe does not fluctuate, the production task continues and the pressure value on the inner wall of the receiving slurry pipe is returned.

[0009] If the pressure value on the inner wall of the slurry pipe fluctuates, it indicates that there is a blockage on the inner wall of the slurry pipe.

[0010] Open the inlet valve of the glue-making machine, inject the cleaning solvent, and use the cleaning solvent to clean the glue-making machine;

[0011] Open the cleaning valve on the glue-making machine to allow the cleaning solvent to enter the coarse grinding mill and coarse grinding tank through the diaphragm pump, and use the cleaning solvent to clean the coarse grinding mill and coarse grinding tank;

[0012] Using a cleaning solvent, the fine grinding tank and the semi-finished product tank are cleaned in sequence, and the cleaning waste liquid is directed into the waste liquid pipeline;

[0013] Cleaning balls are introduced into the waste liquid pipeline to facilitate the discharge of cleaning waste liquid, thereby completing the cleaning operation of the entire slurry pipeline.

[0014] This application also provides a pipeline cleaning system, comprising:

[0015] Industrial control equipment is used to perform the above-mentioned pipeline cleaning methods;

[0016] The glue-making machine system is communicatively connected to the industrial control equipment.

[0017] The diaphragm pump is communicatively connected to the industrial control equipment.

[0018] The coarse grinding mill is communicatively connected to the industrial control equipment.

[0019] The coarse grinding jar is communicatively connected to the industrial control equipment.

[0020] The fine grinding jar is communicatively connected to the industrial control equipment.

[0021] The semi-finished product tank is communicatively connected to the industrial control equipment.

[0022] Multiple liquid inlet valves, each of which is communicatively connected to the industrial control equipment;

[0023] The cleaning device is communicatively connected to the industrial control equipment.

[0024] This application relates to a pipeline cleaning method and system, which receives pressure values ​​from a pressure sensor on the inner wall of the slurry pipeline. The clogging threshold refers to the flow rate or pressure value at which slurry begins to clog the pipeline. If the flow rate or pressure in the pipeline exceeds this threshold, slurry begins to deposit in the pipeline, forming a blockage. The selection of cleaning balls needs to be determined based on the clogging threshold. If the clogging threshold in the pipeline is low, a cleaning ball with better cleaning effect needs to be selected to effectively remove impurities and deposits in the pipeline. If the clogging threshold in the pipeline is high, a more powerful cleaning ball needs to be selected to deal with more severe blockages. During normal operation, the pressure sensor continuously monitors pressure changes in the pipeline. If a significant drop in pressure or large fluctuations are detected (e.g., fluctuations around 35%), it can be determined that the pipeline may be clogged or have slurry accumulation, at which point cleaning is required. The industrial control equipment controls the opening of the inlet valve of the glue-making machine, first adding the cleaning solvent (NMP, added to the glue-making machine first, opening the cleaning valve on the glue-making machine, and then passing it through the diaphragm pump to each subsequent storage tank for pipeline cleaning). The control equipment controls the opening of the discharge valve of the glue-making machine, and the discharge diaphragm pump of the glue-making machine pumps the cleaning solvent into the coarse grinding mill. The discharge valve of the coarse grinding mill is opened, and the solvent is pumped into the coarse grinding tank by the discharge screw pump of the coarse grinding mill. The industrial control equipment controls the opening of the discharge valve of the coarse grinding tank, and the discharge diaphragm pump of the coarse grinding tank pumps the cleaning solvent into the fine grinding tank. The industrial control equipment controls the opening of the discharge valve of the fine grinding tank, and the discharge diaphragm pump of the fine grinding tank pumps the cleaning solvent into the semi-finished product tank. The industrial control equipment controls the opening of the discharge valve of the semi-finished product tank, and the discharge screw pump of the semi-finished product tank pumps the cleaning solvent (now turned into waste liquid) into the waste liquid pipeline. The waste liquid ton is opened, and the waste liquid flows into the waste liquid ton from the waste liquid pipeline.

[0025] The working process of the cleaning ball: The first process relies on compressed air, the cleaning medium, to propel the cleaning machine forward. The cleaning medium generates pressure within the pipeline, pushing the cleaning ball forward. Simultaneously, the design and material of the carbon nanotube cleaning ball also affect its movement within the pipeline, generating friction against the inner wall to increase resistance and achieve better cleaning results. The second process involves magnetic signal devices installed inside the cleaning ball to monitor its real-time position and movement. These devices can connect to an external control system, transmitting detected data. The control system calculates the distance and direction the cleaning ball needs to move based on the received data and generates corresponding control signals. These signals are sent to the cleaning ball's drive system via wireless or wired connection. Upon receiving the control signals, the drive system generates corresponding driving force to propel the cleaning ball within the pipeline. This driving force can be generated by an internal motor, air pump, or other equipment. During the cleaning ball's movement within the pipeline, the control system continuously monitors its position and movement, adjusting the magnitude and direction of the driving force as needed to ensure the cleaning ball moves along a preset path and speed. This application implements automatic control and operation. The control system can monitor the cleaning status inside the pipeline in real time and automatically adjust the cleaning time and cleaning intensity. Attached Figure Description

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0052] This application provides a pipeline cleaning method.

[0053] like Figure 1 As shown in one embodiment of this application, a pipe cleaning method includes:

[0054] S100 receives the pressure value of the inner wall of the slurry pipe.

[0055] S200 determines whether the pressure value inside the slurry pipe fluctuates.

[0056] S300, if the pressure value of the inner wall of the slurry pipe does not fluctuate, the production task continues and the pressure value of the inner wall of the receiving slurry pipe is returned.

[0057] S400, if the pressure value on the inner wall of the slurry pipe fluctuates, it is determined that the inner wall of the slurry pipe is blocked.

[0058] S500: Open the inlet valve of the glue-making machine, inject the cleaning solvent, and use the cleaning solvent to clean the glue-making machine.

[0059] S600, open the cleaning valve on the glue-making machine to allow the cleaning solvent to enter the coarse grinding mill and coarse grinding tank through the diaphragm pump, and use the cleaning solvent to clean the coarse grinding mill and coarse grinding tank.

[0060] The S700 uses a cleaning solvent to sequentially clean the fine grinding tank and the semi-finished product tank, and then directs the cleaning waste liquid into the waste liquid pipeline.

[0061] S800 introduces cleaning balls into the waste liquid pipeline to facilitate the discharge of cleaning waste liquid, thereby completing the cleaning operation of the entire slurry pipeline.

[0062] Specifically, the working process of a cleaning ball:

[0063] The first step involves using compressed air from the cleaning medium to propel the pig forward. The cleaning medium generates pressure within the pipeline, pushing the cleaning balls forward. Simultaneously, the design and material of the carbon nanotube cleaning balls also affect their movement within the pipeline, generating friction against the inner wall to increase resistance and achieve better cleaning results.

[0064] The second process involves a magnetic signal device installed inside the cleaning ball to monitor its real-time position and movement. This device can connect to an external control system, transmitting the detected data. The control system calculates the required distance and direction of movement for the cleaning ball based on the received data and generates corresponding control signals. These signals are sent to the cleaning ball's drive system via wireless or wired connection. Upon receiving the control signals, the drive system generates the appropriate driving force to propel the cleaning ball within the pipe. This driving force can be generated by a built-in motor, air pump, or other equipment. During the cleaning ball's movement within the pipe, the control system continuously monitors its position and movement, adjusting the magnitude and direction of the driving force as needed to ensure the cleaning ball moves along a preset path and speed. This application achieves automatic control and operation. The control system can monitor the cleaning process inside the pipe in real time and automatically adjust the cleaning time and intensity.

[0065] This embodiment relates to a pipeline cleaning method and system, which receives pressure values ​​from a pressure sensor on the inner wall of the slurry pipeline. The blockage threshold refers to the flow rate or pressure value at which slurry begins to cause blockage in the pipeline. If the flow rate or pressure in the pipeline exceeds this threshold, slurry begins to deposit in the pipeline, forming a blockage. The selection of cleaning balls needs to be determined based on the blockage threshold. If the blockage threshold in the pipeline is low, a cleaning ball with better cleaning effect needs to be selected to effectively remove impurities and deposits in the pipeline. If the blockage threshold in the pipeline is high, a more powerful cleaning ball needs to be selected to deal with more severe blockages. During normal operation, the pressure sensor continuously monitors pressure changes in the pipeline. If a significant drop in pressure or large fluctuations are detected (e.g., fluctuations around 35%), it can be determined that the pipeline may be blocked or slurry has accumulated, at which point cleaning is required. The industrial control equipment controls the opening of the inlet valve of the glue-making machine, first adding the cleaning solvent (NMP, added to the glue-making machine first, opening the cleaning valve on the glue-making machine, then passing it through a diaphragm pump to each subsequent storage tank for pipeline cleaning). The equipment then controls the glue-making machine to open its outlet valve, where the outlet diaphragm pump pumps the cleaning solvent into the coarse grinding mill. The coarse grinding mill's outlet valve opens, and the cleaning solvent is pumped into the coarse grinding tank by the coarse grinding mill's outlet screw pump. The industrial control equipment controls the coarse grinding tank to open its outlet valve, where the outlet diaphragm pump pumps the cleaning solvent into the fine grinding tank. The industrial control equipment controls the fine grinding tank to open its outlet valve, where the outlet diaphragm pump pumps the cleaning solvent into the semi-finished product tank. The industrial control equipment controls the semi-finished product tank to open its outlet valve, where the outlet screw pump pumps the cleaning solvent (now waste liquid) into the waste liquid pipeline. The ton container is then opened, and the waste liquid flows into the ton container through the waste liquid pipeline. It is worth noting that the ton container is located after the semi-finished product tank to collect the waste liquid.

[0066] In one embodiment of this application, after S800, the method further includes:

[0067] S111, determine whether the preparation of this batch of conductive agent has been completed.

[0068] S112, if the preparation of the conductive agent for this batch is not completed, the preparation of the remaining conductive agent is continued, and the pressure value of the inner wall of the receiving slurry pipe is returned.

[0069] S113, If the preparation of this batch of conductive agent has been completed, determine whether there is a next batch of conductive agent preparation work that needs to be performed.

[0070] S114. If there is no next batch of conductive agent preparation work to be performed, determine whether there is a work plan for conductive agent preparation work within the next K working days. K is a positive integer and K is greater than 1.

[0071] S115, if there is no work plan for the preparation of conductive agent within the next K working days, then determine the flow of raw materials in the glue-making machine, coarse grinding mill, coarse grinding tank, fine grinding tank and semi-finished product tank.

[0072] S116, according to the raw material flow direction, the step of directly opening the liquid inlet valve of the glue-making machine, injecting cleaning solvent, and using the cleaning solvent to clean the glue-making machine until the cleaning ball is introduced into the waste liquid pipe to realize the discharge of cleaning waste liquid, so as to complete the cleaning operation of the entire slurry pipeline.

[0073] Specifically, in actual production, there are three situations where pipeline cleaning is required. The first is when the conductive slurry production equipment needs to be shut down for an extended period. In this case, the entire pipeline network is essentially empty.

[0074] The liquid cleaning process, from the glue-making machine, coarse grinding tank, fine grinding tank, semi-finished product tank, to the waste liquid tonne tank, is as follows: The inlet valve of the glue-making machine is opened by the industrial control equipment, and the cleaning solvent (NMP) is first added to the glue-making machine. The cleaning valve on the glue-making machine is opened, and then the solvent is sequentially added to the subsequent storage tanks via a diaphragm pump for pipeline cleaning. The glue-making machine's discharge valve is opened, and the cleaning solvent is pumped into the coarse grinding mill by the glue-making machine's discharge diaphragm pump. The coarse grinding mill's discharge valve is opened, and the cleaning solvent is pumped into the coarse grinding mill by the coarse grinding mill's discharge screw pump. The coarse grinding tank is controlled by the industrial control equipment to open its discharge valve, and the cleaning solvent is pumped into the fine grinding tank by the discharge diaphragm pump from the coarse grinding tank. The industrial control equipment then controls the fine grinding tank to open its discharge valve, and the cleaning solvent is pumped into the semi-finished product tank by the discharge diaphragm pump from the semi-finished product tank. Finally, the industrial control equipment controls the semi-finished product tank to open its discharge valve, and the cleaning solvent (now waste liquid) is pumped into the waste liquid pipeline by the discharge screw pump from the semi-finished product tank. The waste liquid ton container is then opened, and the waste liquid flows into the waste liquid ton container from the waste liquid pipeline. It is worth mentioning that the cleaning device itself includes a waste liquid ton container.

[0075] This embodiment relates to a cleaning method for conductive slurry production equipment that needs to be shut down for an extended period. This method offers advantages such as automation, high efficiency, and environmental friendliness. After the cleaning solvent enters the waste liquid pipeline, an automated operation procedure is developed based on actual needs to automate the operation of the ball pushing and collecting device within the waste liquid pipeline. For example, when the pipeline requires cleaning, the control system automatically activates the ball pushing device to push the cleaning balls into the pipeline, and simultaneously activates the ball collecting device to retrieve the cleaned balls, completing the cleaning operation. This method is suitable for cleaning various pipelines, such as slurry pipelines, cooling water pipelines, refrigeration pipelines, and steam pipelines.

[0076] In one embodiment of this application, after S114, the method further includes:

[0077] S121, the steps of directly opening the inlet valve of the glue-making machine, injecting cleaning solvent, and using the cleaning solvent to clean the glue-making machine until the cleaning ball is introduced into the waste liquid pipe to realize the discharge of cleaning waste liquid, thereby completing the cleaning operation of the entire slurry pipeline.

[0078] Specifically, in actual production, there are three situations that require pipeline cleaning. The second situation is when it is necessary to change the batch of conductive paste production. At this time, the entire pipeline network is basically filled with raw materials, semi-finished products, and finished products. In this case, it is necessary to drain the raw materials, semi-finished products, and finished products from the pipeline to achieve a basically empty pipeline network.

[0079] While one semi-finished product tank is being cleaned or maintained, another semi-finished product tank can continue production, thus reducing downtime and improving production efficiency. The system consists of a glue-making machine, coarse grinding tank, fine grinding tank, semi-finished product tank, and finally, a production storage tank. Pressure sensors are installed at key locations in the slurry pipeline (near the bends and in the middle of the pipeline between the outlet valve of each storage tank and the inlet valve of the next storage tank). During normal operation, pressure changes in the pipeline (pressure sensors are located in the slurry outlet pipeline) are continuously monitored. If a significant drop in pressure or large fluctuations are detected (fluctuations within approximately 35%), it can be determined that there may be a blockage or slurry accumulation in the pipeline, requiring cleaning. When no blockage occurs, this entire pipeline primarily relies on this channel for the transport of raw materials, semi-finished products, and finished products.

[0080] The industrial control equipment controls the opening of the inlet valve of the glue-making machine, and then controls the opening of the outlet valve of the glue-making machine to discharge the material. The discharge diaphragm pump of the glue-making machine pumps the semi-finished product into the coarse grinding mill. The discharge valve of the coarse grinding mill is opened, and the semi-finished product is coarsely ground and discharged. The screw pump pumps the semi-finished product into the coarse grinding tank. The industrial control equipment controls the opening of the outlet valve of the coarse grinding tank, and the discharge diaphragm pump of the coarse grinding tank pumps the coarsely ground semi-finished product into the fine grinding tank for fine grinding. The industrial control equipment controls the opening of the outlet valve of the fine grinding tank, and the discharge diaphragm pump of the fine grinding tank pumps the finely ground semi-finished product into the semi-finished product tank. The industrial control equipment controls the opening of the outlet valve of the semi-finished product tank, and the discharge screw pump of the semi-finished product tank pumps the finished product into the production storage tank.

[0081] The following steps are then repeated: The liquid cleaning process from the glue-making machine, coarse grinding tank, fine grinding tank, semi-finished product tank, to the waste liquid tonne tank: The inlet valve of the glue-making machine is opened by the industrial control equipment, and the cleaning solvent (NMP) is added first to the glue-making machine. The cleaning valve on the glue-making machine is opened, and then the solvent is sequentially added to the subsequent storage tanks via a diaphragm pump for pipeline cleaning. The glue-making machine's outlet valve is opened, and the cleaning solvent is pumped into the coarse grinding mill by the glue-making machine's outlet diaphragm pump. The coarse grinding mill's outlet valve... The solvent is pumped into the coarse grinding tank by the discharge screw pump of the coarse grinding mill. The industrial control equipment controls the coarse grinding tank to open the discharge valve, and the discharge diaphragm pump of the coarse grinding tank pumps the cleaning solvent into the fine grinding tank. The industrial control equipment controls the fine grinding tank to open the discharge valve, and the discharge diaphragm pump of the fine grinding tank pumps the cleaning solvent into the semi-finished product tank. The industrial control equipment controls the semi-finished product tank to open the discharge valve, and the discharge screw pump of the semi-finished product tank pumps the cleaning solvent (which has now become waste liquid) into the waste liquid pipeline. The ton container is opened, and the waste liquid flows into the waste liquid ton container from the waste liquid pipeline.

[0082] This embodiment relates to a cleaning method for pipelines when it is necessary to change the batch size of conductive slurry production. This method has advantages such as automation, high efficiency, and environmental friendliness. After the cleaning solvent enters the waste liquid pipeline, an automated operation procedure is programmed according to actual needs to automate the operation of the ball pushing and collecting device within the waste liquid pipeline. For example, when the pipeline needs cleaning, the control system automatically starts the ball pushing device to push the cleaning balls into the pipeline, and simultaneously starts the ball collecting device to retrieve the cleaned balls, completing the cleaning operation. This method is suitable for cleaning various pipelines, such as slurry pipelines, cooling water pipelines, refrigeration pipelines, and steam pipelines.

[0083] In one embodiment of this application, S500 includes:

[0084] S511, Read the number of times the glue-making machine has been cleaned. The number of times the glue-making machine has been cleaned has an initial value, and the initial value is 0.

[0085] S512, open the inlet valve of the glue-making machine and inject the cleaning solvent.

[0086] S513 mixes and stirs the cleaning solvent with the remaining material inside the glue-making machine through the dispersion disc inside the glue-making machine.

[0087] S514, the mixed cleaning solvent and residue are introduced into the diaphragm pump.

[0088] S515, add 1 to the original value of the number of cleaning cycles for the glue-making machine.

[0089] S516, return to the step of opening the liquid inlet valve of the glue-making machine and injecting cleaning solvent until the preset number of cleaning cycles is reached.

[0090] Specifically, in actual production, there are three situations that require pipeline cleaning. The third is when pipeline blockage occurs during production. This is because the pipeline layout is complex, inevitably containing numerous bends and significant angle changes. These factors can impede the flow of slurry within the pipeline, leading to accumulation. Furthermore, the slurry contains a large number of fine particles or impurities, which easily deposit and accumulate within the pipeline.

[0091] This embodiment relates to a method for cleaning the internal cavity of a glue-making machine. The method utilizes carbon nanomaterials, enabling rapid cleaning of dirt and impurities inside the pipes. A ball-collecting device collects and filters out impurities and dirt, improving the pipe's flowability and heat transfer efficiency. This technical solution is simple to operate, easy to implement, and easy to maintain.

[0092] In one embodiment of this application, S600 includes:

[0093] S611, Read the number of cleaning cycles of the coarse grinding mill. The number of cleaning cycles of the coarse grinding mill has an initial value, and the initial value is 0.

[0094] S612 uses a diaphragm pump to introduce the cleaning solvent and residual material from the glue-making machine into the coarse grinding mill.

[0095] S613 uses a coarse grinding mill and a coarse grinding tank to grind the cleaning solvent, the residue inside the glue-making machine, and the residue inside the coarse grinding mill.

[0096] S614 introduces the ground mixture into the glue-making machine.

[0097] S615, add 1 to the original value of the number of cleaning cycles for the coarse grinding mill.

[0098] S616, return to the step of using a diaphragm pump to introduce the cleaning solvent and residual material inside the glue-making machine into the coarse grinding mill until the coarse grinding mill has been cleaned a preset number of times.

[0099] Specifically, the coarse grinding mill can be designed as a dual-unit system. While one mill is grinding, the other can be used for loading or unloading, thus reducing downtime. Simultaneously, the dual-mill design also improves cleaning efficiency, as the two mills can be used alternately, ensuring both are thoroughly cleaned. One mill is in operation, while the other serves as a backup for cleaning. This ensures that if the main coarse grinding mill malfunctions or requires maintenance, the backup mill can be promptly put into use, guaranteeing production continuity and stability.

[0100] This embodiment relates to a method for cleaning the internal cavity of a coarse grinding mill. The method utilizes carbon nanomaterials to quickly clean dirt and impurities inside the pipes, fully leveraging the mechanical force of the coarse grinding mill itself during the cleaning process. A ball-collecting device collects and filters out impurities and dirt, improving the flowability and heat transfer efficiency of the pipes. This technical solution is simple to operate, easy to implement, and easy to maintain.

[0101] In one embodiment of this application, S600 further includes:

[0102] S621, after the coarse grinding mill has completed a preset number of cleaning cycles, the cleaned mixture is discharged from the glue-making machine to the diaphragm pump.

[0103] S622, a clean cleaning solvent is fed into the coarse mill; the cleaning solvent dilutes the mixture to form a diluted mixture.

[0104] S623, the coarse grinding mill performs grinding operations and opens the discharge valve of the coarse grinding mill to pump the diluted mixture into the coarse grinding tank through the discharge screw pump of the coarse grinding mill and clean the coarse grinding tank.

[0105] S624, open the discharge valve of the coarse grinding tank, and the discharge diaphragm pump of the coarse grinding tank will pump the mixture output from the coarse grinding tank into the fine grinding tank.

[0106] Specifically, the coarse grinding mill can be designed as a dual-unit system. While one mill is grinding, the other can be used for loading or unloading, thus reducing downtime. Simultaneously, the dual-mill design also improves cleaning efficiency, as the two mills can be used alternately, ensuring both are thoroughly cleaned. One mill is in operation, while the other serves as a backup for cleaning. This ensures that if the main coarse grinding mill malfunctions or requires maintenance, the backup mill can be promptly put into use, guaranteeing production continuity and stability.

[0107] The liquid cleaning process, from the glue-making machine, coarse grinding tank, fine grinding tank, semi-finished product tank, to the waste liquid ton container, is as follows: The industrial control equipment opens the inlet valve of the glue-making machine, first adding the cleaning solvent (NMP, added to the glue-making machine first, then opening the cleaning valve on the glue-making machine, and then passing it through a diaphragm pump to each subsequent storage tank for pipeline cleaning). The control equipment then opens the outlet valve of the glue-making machine, and the outlet diaphragm pump of the glue-making machine pumps the cleaning solvent into the coarse grinding mill. The outlet valve of the coarse grinding mill opens, and the solvent is pumped into the coarse grinding tank by the coarse grinding mill outlet screw pump. The industrial control equipment controls the coarse grinding tank to open its outlet valve, and the outlet diaphragm pump of the coarse grinding tank pumps the cleaning solvent into the fine grinding tank. The industrial control equipment then controls the fine grinding tank to open its outlet valve, and the outlet diaphragm pump of the fine grinding tank pumps the cleaning solvent into the semi-finished product tank.

[0108] This embodiment relates to a method for cleaning the internal cavity of a coarse grinding mill. The method utilizes carbon nanomaterials to quickly clean dirt and impurities inside the pipes, fully leveraging the mechanical force of the coarse grinding mill itself during the cleaning process. A ball-collecting device collects and filters out impurities and dirt, improving the flowability and heat transfer efficiency of the pipes. This technical solution is simple to operate, easy to implement, and easy to maintain.

[0109] In one embodiment of this application, S700 includes:

[0110] S711, the fine grinding jar further grinds the mixture output from the coarse grinding jar to clean the inner wall of the fine grinding jar.

[0111] S712 controls the fine grinding jar to open the discharge valve.

[0112] S713, the diaphragm pump from the fine grinding tank pumps the mixture output from the fine grinding tank into the semi-finished product tank, so that the discharge cleans the inner wall of the semi-finished product tank.

[0113] S714, open the discharge valve of the semi-finished product tank to allow the cleaning waste liquid to be introduced into the waste liquid pipeline.

[0114] Specifically, the design of two semi-finished product tanks can also improve cleaning efficiency. For example, while one semi-finished product tank is being cleaned or maintained, the other semi-finished product tank can continue production, thereby reducing downtime and improving production efficiency.

[0115] The industrial control equipment controls the fine grinding tank to open the discharge valve, and the fine grinding tank discharge diaphragm pump pumps the cleaning solvent into the semi-finished product tank. The industrial control equipment controls the semi-finished product tank to open the discharge valve, and the semi-finished product tank discharge screw pump pumps the cleaning solvent (which has now become waste liquid) into the waste liquid pipeline. The ton container is opened, and the waste liquid flows into the waste liquid ton container from the waste liquid pipeline.

[0116] This embodiment relates to a method for cleaning the inner cavity of a semi-finished product tank. It is made of carbon nanomaterials, enabling rapid cleaning of dirt and impurities inside the pipeline. Simultaneously, the internal tank wall is cleaned using the production process of the semi-finished product tank itself. This technical solution is applicable to the cleaning of various pipelines, such as slurry pipelines, cooling water pipelines, refrigeration pipelines, and steam pipelines. This technical solution is simple to operate, easy to implement, and easy to maintain.

[0117] In one embodiment of this application, S800 includes:

[0118] S811, Select a cleaning ball that matches the diameter of the waste liquid pipe.

[0119] S812, with magnets installed inside the cleaning ball.

[0120] The S813 uses compressed air to propel the cleaning ball through the waste liquid pipe.

[0121] S814 receives the magnetic signal from the cleaning ball. The magnetic signal from the cleaning ball is used to communicate with a sensor installed on the outer wall of the waste liquid pipeline.

[0122] S815: Acquire sensor data sent by a sensor installed on the outer wall of the waste liquid pipe, and determine the real-time position and movement status of the cleaning ball based on the sensor data.

[0123] Specifically, the cleaning device mainly consists of cleaning balls, a pushing device, a receiving device, and a control system. Based on the size and material of the pushing pipe, a cleaning ball device slightly larger than the pipe is selected. The diameter of the cleaning ball is slightly larger than the diameter of the slurry pipe. The cleaning ball is made of carbon nanomaterials, possessing strong adsorption and mechanical force, enabling it to quickly clean dirt and impurities inside the pipe. The entire cleaning process of the cleaning ball ensures complete coverage of the entire interior of the slurry pipe.

[0124] This embodiment relates to the placement of a cleaning device. A slightly larger cleaning ball can better adapt to the shape and size of the pipe, thus cleaning the inside of the pipe more thoroughly. Using a slightly larger cleaning ball reduces the risk of the ball getting stuck in the pipe. If the cleaning ball is too small, it may get stuck in bends or narrow sections of the pipe, causing the cleaning operation to fail. A larger cleaning ball can pass through the pipe more easily, reducing the difficulty of operation. At the same time, a larger cleaning ball is also easier to push, thereby reducing cleaning time and labor costs.

[0125] In one embodiment of this application, S800 further includes:

[0126] S821 receives real-time data on the position and motion status of the cleaning ball.

[0127] S822 calculates the distance and direction the cleaning ball needs to move in order to generate a control signal.

[0128] S823, based on a control signal, propels the cleaning ball to move within the pipe. The driving force propelling the cleaning ball within the pipe is generated by one or more devices, including a built-in motor and an air pump.

[0129] Specifically, position sensors are installed at appropriate locations in the ball-pushing pipeline to detect the presence and position of the balls, monitor the ball-pushing and ball-retrieving status in real time, and feed the signals back to the control system. The control system adjusts the operating status of the ball-pushing and ball-retrieving devices based on the sensor feedback signals, achieving automated control. When the pressure sensor of the ball-pushing device senses slurry accumulation in the slurry pipeline, the cleaning ball is pushed from the cleaning box into the sending device and emitted. Through the coordination of the front-end air inlet valve, the tail-end exhaust valve, the ball-pushing control valve, the tail-end discharge valve, and the drain valve, a forward ball-pushing cleaning operation is achieved. After cleaning, cleaning liquid is introduced through the liquid inlet valve to rinse the cleaning ball, which is then discharged through the liquid outlet valve. This allows for cleaning and self-cleaning without removing the cleaning ball, eliminating the need for ball placement and removal for each cleaning operation; only an initial ball placement is required. The control system can monitor the cleaning status inside the pipeline in real time and automatically adjust the cleaning time and intensity.

[0130] This embodiment relates to a method for placing a cleaning device. The ball-collecting device can collect and filter out impurities and dirt, improving the flowability and heat transfer efficiency of the pipeline. The ball-collecting device can also transport the filtered liquid out, reducing wastewater discharge. The ball-collecting device adopts an automated design, enabling automatic control and operation. It is suitable for cleaning various pipelines, such as slurry pipelines, cooling water pipelines, refrigeration pipelines, and steam pipelines. The ball-collecting device is suitable for various types of wastewater treatment and discharge.

[0131] This application provides a pipeline cleaning system.

[0132] like Figure 2 As shown, in one embodiment of this application, a pipeline cleaning system is provided, including an industrial control device 100, a glue-making machine system 200, a diaphragm pump 300, a coarse grinder 400, a coarse grinding tank 500, a fine grinding tank 600, a semi-finished product tank 700, an inlet valve 800, and a cleaning device 900.

[0133] It should be noted that the glue-making machine in the aforementioned pipeline cleaning method in this application is the same device as the glue-making machine system 200 in this embodiment.

[0134] The industrial control equipment 100 is used to execute the pipeline cleaning method mentioned in any of the above embodiments.

[0135] The glue-making machine system 200 is communicatively connected to the industrial control equipment 100.

[0136] The diaphragm pump 300 is communicatively connected to the industrial control equipment 100.

[0137] The coarse grinding mill 400 is communicatively connected to the industrial control equipment 100.

[0138] The coarse grinding jar 500 is communicatively connected to the industrial control equipment 100.

[0139] The fine grinding jar 600 is communicatively connected to the industrial control equipment 100.

[0140] The semi-finished product tank 700 is communicatively connected to the industrial control equipment 100.

[0141] Each of the liquid inlet valves 800 is communicatively connected to the industrial control equipment 100.

[0142] The cleaning device 900 is communicatively connected to the industrial control equipment 100.

[0143] This embodiment relates to a pipeline cleaning system. The industrial control equipment 100, by setting the amount of raw material NMP, delivers a fixed quantity of NMP to the glue-making machine system 200. Raw material solids, including graphite and carbon black, are added to the glue-making machine system 200, along with a dispersant. The weight is set, and the glue-making machine system 200 automatically draws in the dispersant. The dispersant intake error is within 0.3%. Simultaneously, the mixer within the glue-making machine system 200 operates a coarse grinder 400 for coarse grinding and allows a fine grinder for fine grinding. Based on real-time slurry monitoring data, if the results exceed expectations, the system automatically adjusts the formulation strategy to avoid risks such as slurry quality degradation or even spoilage. Specifically, as the higher the rotational speed of the coarse grinding mill 400, the higher the grinding efficiency, the increased temperature will have a certain impact on the particles, which is detrimental to obtaining better particles. High temperature causes particle molecular aggregation. Therefore, in the glue-making machine system 200, the raw material NMP and raw material solids need to be stirred, and then the dispersion disc in the glue-making machine system 200 is used to disperse the mixed clumps of raw material NMP and raw material solids. The initially dispersed raw material can be coarsely ground using the coarse grinding mill 400. The grinding media of the coarse grinding mill 400 is selected as zirconia beads, which have a high specific gravity, high strength, high energy, and high grinding efficiency. The rotor speed of the coarse grinding mill can be selected from 300 rpm / min to 500 rpm / min. Generally, the grinding time is inversely proportional to the rotor speed. When the coarseness of the product from coarse grinding is lower than the coarseness threshold of fine grinding, the coarse grinding product is introduced from coarse grinding tank 500 into fine grinding tank 600 for fine grinding to produce the target product. This ensures both grinding precision and grinding efficiency.

[0144] This adhesive preparation method boasts high production efficiency and a high yield. During the cleaning process: the industrial control equipment 100 controls the opening of the inlet valve 800 of the adhesive preparation system 200, first adding the cleaning solvent (NMP, added initially to the adhesive preparation system 200, opening the cleaning valve on the adhesive preparation system 200, and then sequentially reaching the subsequent storage tanks via the diaphragm pump 300 for pipeline cleaning). The control equipment 100 then opens the outlet valve of the adhesive preparation system 200, and the diaphragm pump 300, used for discharging, pumps the cleaning solvent into the coarse grinding mill 400. The outlet valve of the coarse grinding mill 400 opens, and the cleaning solvent is pumped into the coarse grinding tank by the discharge screw pump of the coarse grinding mill 400. Industrial control equipment 100 controls the coarse grinding tank 500 to open the discharge valve, and the discharge diaphragm pump of the coarse grinding tank 500 pumps the cleaning solvent into the fine grinding tank 600. Industrial control equipment 100 controls the fine grinding tank 600 to open the discharge valve, and the discharge diaphragm pump of the fine grinding tank 600 pumps the cleaning solvent into the semi-finished product tank 700. Industrial control equipment 100 controls the semi-finished product tank 700 to open the discharge valve, and the discharge screw pump of the semi-finished product tank 700 pumps the cleaning solvent (which has now become waste liquid) into the waste liquid pipeline. The cleaning device 900 cleans the waste liquid pipeline, and then the ton container is opened, and the waste liquid flows into the ton container from the waste liquid pipeline.

[0145] like Figures 3 to 11 As shown, in another embodiment of this application, a detailed structural diagram of the various parts of a conductive paste preparation system using a cleaning device is provided to provide a more intuitive understanding of the above-described pipe cleaning method.

The semi-finished product tank A710 in this embodiment is equivalent to the semi-finished product tank 700 in the aforementioned pipeline cleaning system embodiment. They will not be described in detail again, but can be understood by those skilled in the art by reading the drawings.

[0147] The technical features of the embodiments described above can be combined arbitrarily, and the execution order of the method steps is not limited. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification.
