Abstract
Description
Technical Field
[0001] This invention relates to the field of mechanical equipment technology, and in particular to a ball-pushing device for slurry pipelines. Background Technology
[0002] Lithium-ion battery slurry is transported through pipelines during production, and the inner walls of these pipelines often accumulate deposits. Especially when production stops, if not cleaned promptly, the remaining slurry can adhere to the pipeline walls, causing clumping. When production resumes, this can impact the transport efficiency of the lithium-ion battery slurry, and in severe cases, may lead to blockages, preventing smooth transport.
[0003] In existing technologies, a sphere or cleaning device with a diameter slightly smaller than the inner diameter of the conveying pipe is commonly used. This sphere is inserted into the conveying pipe to be cleaned, and under pressure, it passes through the pipe, removing any adhering substances. Chinese Patent CN219965865U discloses an electrode slurry conveying pipe cleaning device, belonging to the field of electrode slurry cleaning technology. It includes a scraping section, a pushing section, and a connecting section fixedly connected between the scraping section and the pushing section. The bodies of the scraping section, the pushing section, and the connecting section are all cylindrical and coaxially arranged. The diameters of the scraping section and the pushing section are both smaller than the inner diameter of the conveying pipe. A soft scraping ring is provided on the scraping section, and a soft pushing ring is provided on the pushing section. Both the scraping ring and the pushing ring are interference-fitted with the conveying pipe. The scraping ring has multiple notches. This invention can clean slurry conveying pipes, reduce the risk of slurry sticking to the walls and clumping, improve slurry conveying efficiency, and avoid the risk of mixing when conveying different types of slurry.
[0004] However, in the cleaning device, the cleaning component does not participate in sealing the space between the cleaning chamber and the delivery pipeline. When the pig returns to the pig cage to clean the slurry in the pipeline after cleaning the pig, the cleaning liquid flows from the chamber into the delivery pipeline, resulting in a large amount of cleaning fluid being needed to flush the pig. To address this waste of cleaning fluid due to the flow from the cleaning chamber into the delivery pipeline, the existing pig system structure can only add a valve between the cleaning chamber and the delivery pipeline for sealing and isolation. The valve is then opened after the pig cleaning to drain the cleaning fluid from the delivery pipeline. Furthermore, the pig is a consumable component in the entire system, and the existing structure lacks any direct detection method for damage during pig cleaning.
[0005] Therefore, it is necessary to provide a slurry pipeline ball pusher that has its own seal and can effectively detect the usage of cleaning components. Summary of the Invention
[0006] The purpose of this invention is to provide a slurry pipeline ball pushing device that has a self-sealing function and can effectively detect the usage status of cleaning components.
[0007] To achieve the above objectives, the present invention provides a slurry pipeline pigging device, comprising a cleaning mechanism, a feeding mechanism, a slurry feeding mechanism, a slurry delivery mechanism, and a discharge mechanism. The cleaning mechanism includes a cleaning chamber and a pigging ball. The feeding mechanism, the slurry delivery mechanism, and the discharge mechanism are all connected to the cleaning chamber. The feeding mechanism is connected to the slurry delivery mechanism. The pigging ball can slide into the cleaning chamber and seal and isolate the cleaning chamber from the slurry delivery mechanism. The feeding mechanism is used to introduce gas and / or liquid into the cleaning chamber to clean the pigging ball inside the cleaning chamber. The gas and liquid inside the cleaning chamber are discharged through the discharge mechanism. Alternatively, the feeding mechanism can introduce gas and / or liquid to push the pigging ball into the slurry delivery mechanism. The slurry feeding mechanism is used to introduce slurry into the slurry delivery mechanism, and the slurry delivery mechanism is used to convey the slurry. The pigging ball is conveyed within the slurry delivery mechanism by means of gas / liquid / slurry to clean the slurry delivery mechanism.
[0008] With the above technical solution, the slurry pipeline ball pushing device of the present invention includes a cleaning mechanism, a feeding mechanism, a slurry feeding mechanism, a slurry delivery mechanism, and a discharging mechanism. The cleaning mechanism includes a cleaning chamber and a pigging ball. The feeding mechanism provides gas and liquid to the cleaning chamber to clean the pigging ball inside. The pigging ball seals and isolates the cleaning chamber from the slurry delivery mechanism to prevent the gas and liquid used for cleaning from entering the slurry delivery mechanism. The gas and liquid used to clean the pigging ball are discharged by the discharging mechanism, ensuring that the slurry in the slurry delivery mechanism does not mix with the cleaning liquid. The cleaning chamber and the slurry delivery mechanism are sealed by the pigging ball, eliminating the need to close additional valves when cleaning the pigging ball. Furthermore, in some cases, after the pigging ball has cleaned some products in the pipeline, it can be directly cleaned without flushing the pipeline, eliminating the need for additional valves and control procedures to prevent the cleaning liquid from entering the slurry delivery mechanism. This not only makes operation more convenient but also avoids significant waste of cleaning liquid. The feeding mechanism introduces slurry into the slurry delivery mechanism. The slurry delivery mechanism conveys the slurry. The discharge mechanism is used to discharge gas and liquid. When the pigging ball is conveyed within the slurry delivery mechanism, it can clean the pipeline of the slurry delivery mechanism. The pigging ball can be conveyed by pushing gas / liquid / slurry. The pigging ball in this invention has a built-in sealing function, which can effectively isolate the cleaning chamber from the slurry delivery mechanism, making the structure simpler and the operation more convenient.

[0035] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0036] Please see Figures 1 to 3 This invention provides a slurry pipeline pigging device 100, including a cleaning mechanism 10, a feeding mechanism 20, a slurry feeding mechanism 40, a slurry delivery mechanism 30, and a discharge mechanism 50. The cleaning mechanism 10 includes a cleaning chamber 11 and a pigging ball 12. The feeding mechanism 20, the slurry delivery mechanism 30, and the discharge mechanism 50 are all connected to the cleaning chamber 11, and the feeding mechanism 40 is connected to the slurry delivery mechanism 30. The pigging ball 12 can slide into the cleaning chamber 11 and seal and isolate the cleaning chamber 11 from the slurry delivery mechanism 30, so that the pigging ball 12 can be cleaned within the cleaning chamber 11 without the cleaning fluid entering the slurry delivery mechanism 30. The feeding mechanism 20 is used to introduce gas and / or liquid into the cleaning chamber 11 to clean the pigging ball 12 within the cleaning chamber 11. After cleaning the pigging ball 12, the gas and liquid in the cleaning chamber 11 are discharged through the discharge mechanism 50, eliminating the need to discharge the cleaning fluid through the pipeline of the slurry delivery mechanism 30, thus making operation more convenient. On the other hand, gas and / or liquid can be introduced into the feeding mechanism 20 to push the pigging ball 12 into the slurry delivery mechanism 30, thereby cleaning the pipeline of the slurry delivery mechanism 30. The slurry feeding mechanism 40 is used to introduce slurry into the slurry delivery mechanism 30, and the slurry delivery mechanism 30 is used to convey the slurry. In this embodiment, gas / liquid / slurry can be used to enable the pigging ball 12 to be conveyed within the slurry delivery mechanism 30 for cleaning. It is understood that the conveying of the pigging ball 12 within the slurry delivery mechanism 30 can be propelled by the gas / liquid output from the feeding mechanism 20, and can also be propelled by the slurry output from the slurry feeding mechanism 40. That is, during the slurry delivery process, the slurry delivery pipeline 31 can also be cleaned simultaneously to reduce the adhesion of slurry to the slurry delivery pipeline 31.
[0037] With the above technical solution, the slurry pipeline ball pushing device 100 of the present invention includes a cleaning mechanism 10, a feeding mechanism 20, a slurry feeding mechanism 40, a slurry delivery mechanism 30, and a discharge mechanism 50. The cleaning mechanism 10 includes a cleaning chamber 11 and a pigging ball 12. The feeding mechanism 20 provides gas and liquid to the cleaning chamber 11 to clean the pigging ball 12 within the cleaning chamber 11. The pigging ball 12 seals and isolates the cleaning chamber 11 from the slurry delivery mechanism 30 to prevent the gas and liquid used for cleaning from entering the slurry delivery mechanism 30. The gas and liquid used to clean the pigging ball 12 are discharged through the discharge mechanism 50, ensuring that the slurry in the slurry delivery mechanism 30 does not mix with the cleaning liquid. The cleaning chamber 11 and the slurry delivery mechanism 30 are sealed together by the pigging ball 12, eliminating the need to additionally close valves when cleaning the pigging ball 12. Meanwhile, in some cases, after the pigging ball 12 cleans products from certain pipelines, it can be directly cleaned without flushing the pipeline, eliminating the need for additional valves and control procedures to prevent cleaning fluid from entering the slurry delivery mechanism 30. This not only makes operation more convenient but also avoids significant waste of cleaning fluid. The slurry inlet mechanism 40 is used to introduce slurry into the slurry delivery mechanism 30. The slurry delivery mechanism 30 is used to convey the slurry. The outlet mechanism 50 is used to discharge gas and liquid. When the pigging ball 12 is conveyed within the slurry delivery mechanism 30, it can clean the pipeline of the slurry delivery mechanism 30. The conveying of the pigging ball 12 can be achieved by pushing gas / liquid / slurry. The pigging ball 12 in this invention has a built-in sealing function, which can effectively isolate the cleaning chamber 11 from the slurry delivery mechanism 30, making the structure simpler and the operation more convenient.
[0038] Please see Figures 1 to 4 and Figure 6In some optional embodiments, a positioning detection component 13 is provided at the end of the cleaning chamber 11 away from the slurry feeding mechanism 30. The positioning detection component 13 determines that the pigging ball 12 is located within the cleaning chamber 11, thereby enabling the feeding mechanism 20 to open and clean the pigging ball 12 within the cleaning chamber 11. Specifically, the positioning detection component 13 includes a positioning detection cylinder 132 and a push rod 131 located at the output end of the positioning detection cylinder 132. One end of the push rod 131 extends into the cleaning chamber 11, which is formed by a hollow shell 110 and is located within the shell 110. A sealing element 1311 is provided between the push rod 131 and the shell 110 to ensure the airtightness of the cleaning chamber 11. One end of the push rod 131 is provided with a pushing part 1312, the cross-sectional area of which is larger than that of the push rod 131, so that the pushing part 1312 is always positioned within the cleaning chamber 11. When the feeding mechanism 20 or feeding mechanism 40 at the other end of the slurry feeding mechanism 30 sends the pigging ball 12 back into the cleaning chamber 11 at that end via gas / liquid / slurry, the pigging ball 12 contacts the pushing part 1312 of the push rod 131, causing the push rod 131 to partially retract out of the cleaning chamber 11. An inductive switch 133 is installed on the positioning detection cylinder 132. When the pigging ball 12 enters the cleaning chamber 11 and pushes the push rod 131, the push rod 131 moves to a preset position, triggering the inductive switch 133. The inductive switch 133 provides information to confirm that the pigging ball 12 is in position, thus enabling cleaning of the pigging ball 12. The preset position is the position where half of the pigging ball 12 is located inside the cleaning chamber 11, and the other half of the pigging ball 12 seals the passage between the slurry feeding pipe 31 and the cleaning chamber 11. The length of the cleaning chamber 11 is shorter than the length of the pig 12. After the pig 12 has finished cleaning the pipeline and is locked in the cleaning chamber 11, the cleaning fluid can be introduced through the feeding mechanism 20 to clean the portion of the pig 12 within the cleaning chamber. The cleaning chamber 11 can only hold approximately three-quarters of the pig 12, so when the pig 12 is in the cleaning chamber 11, it can completely isolate the cleaning chamber 11 from the slurry delivery mechanism 30. During cleaning, the cleaning fluid can only remain in the cleaning chamber 11 and is discharged through the discharge mechanism 50, preventing it from entering the slurry delivery pipeline 31 of the slurry delivery mechanism 30. The pig 12 on the other side is cleaned in the cleaning chamber 11 at the other end. The structure of the receiving end and the launching end is the same. That is, the structure of the cleaning chambers 11 on both sides of the slurry delivery pipeline 31 is the same. After cleaning one side of the pig 12, the other side of the pig 12 is then cleaned.
[0039] Please see Figures 1 to 4 and Figure 7In some optional embodiments, the slurry delivery mechanism 30 includes a slurry delivery pipe 31 that communicates with the cleaning chamber 11. A baffle assembly 60 is provided on the slurry delivery pipe 31. The baffle assembly 60 includes a baffle cylinder 62 and a baffle rod 61, with the baffle rod 61 mounted on the output end of the baffle cylinder 62. When the feeding mechanism 20 or slurry delivery mechanism 40 at the other end sends the pigging ball 12 back into the cleaning chamber 11 at that end via gas / liquid / slurry, the inductive switch 133 senses that the pigging ball 12 is in position, and the baffle cylinder 62 actuates to extend the baffle rod 61, thereby locking the pigging ball 12. The baffle rod 61 has a smooth structure to reduce friction between the baffle rod 61 and the pigging ball 12. The pigging ball 12 is locked by the baffle assembly 60 for better cleaning, and the pigging ball 12 will not shift during the cleaning process, preventing cleaning fluid from entering the slurry delivery pipe 31. Understandably, one end of the positioned pigging ball 12 is located inside the cleaning chamber 11, and the other end extends into the slurry delivery pipe 31, effectively isolating the cleaning chamber from the slurry delivery pipe 31. The slurry delivery pipe 31 has a through hole for the baffle rod 61 to extend into. The baffle rod 61 is equipped with a fixing member 63 and a sealing block 64. The fixing member 63 secures the baffle cylinder 62 and the baffle rod 61 to the slurry delivery pipe 31, while the sealing block 64 seals the gap between the baffle rod 61 and the slurry delivery pipe 31 to prevent leakage.
[0040] Please see Figure 4 and Figure 5 In some optional embodiments, the pigging ball 12 includes a first ball 121 and a second ball 122, which are symmetrically arranged and integrally formed. An inwardly recessed groove 123 is provided between the first ball 121 and the second ball 122. The groove 123 facilitates the turning of the pigging ball 12 at bends in the slurry delivery pipe 31, allowing the pigging ball 12 to pass smoothly through various bends regardless of the pipe's shape. It is understood that both the first ball 121 and the second ball 122 are interference-fitted with the slurry delivery pipe 31 when sliding within it. When the first ball 121 is in the cleaning chamber 11 on one side, the second ball 122 seals and isolates the cleaning chamber 11 from the slurry delivery pipe 31. When the second sphere 122 is in the cleaning chamber 11 on the other side, the first sphere 121 seals and isolates the cleaning chamber 11 on this side from the slurry delivery pipe 31. The first sphere 121 and the second sphere 122 can both be spherical, or both can be ellipsoidal, or one sphere can be spherical and the other ellipsoidal. Of course, the first sphere 121 and the second sphere 122 can also be other reasonable structures capable of cleaning and sealing the pipe.
[0041] Please see Figure 1In some optional embodiments, both ends of the slurry delivery pipe 31 are provided with cleaning chambers 11. Each cleaning chamber 11 has the same structure, and each cleaning chamber 11 is correspondingly connected to a feeding mechanism 20 and a discharging mechanism 50. The first ball 121 and the second ball 122 are both interference-fitted with the slurry delivery pipe 31. When the pigging ball 12 is engaged with the cleaning chamber 11, the first ball 121 or the second ball 122 is located inside the cleaning chamber 11, and the second ball 122 or the first ball 121 seals the slurry delivery pipe 31 to isolate it from the cleaning chamber 11. After the corresponding baffle assembly 60 locks the pigging ball 12, the corresponding feeding mechanism 20 is activated to clean the first ball 121 or the second ball 122 inside the corresponding cleaning chamber 11.
[0042] Please see Figure 3 In some optional embodiments, the discharge mechanism 50 includes a discharge pipe 51 communicating with the cleaning chamber 11, and a first valve 52 is provided on the discharge pipe 51 to open and close it. When the cleaning chamber needs to discharge cleaning fluid, the first valve 52 is opened, and the cleaning fluid used to clean the pigging ball 12 is discharged from the discharge pipe 51. A pressure detection component can also be provided on the discharge pipe 51, or pressure detection can be performed using an external detection component. It is understood that when the first ball 121 or the second ball 122 is located in the cleaning chamber 11, the second ball 122 or the first ball 121 seals the slurry delivery pipe 31. At this time, the feeding mechanism 20 is closed, and then the first valve 52 is opened. If the detection component detects continuous venting and depressurization on the discharge pipe 51, it indicates that the pigging ball 12 is damaged and can no longer seal the slurry delivery pipe 31. The worn pigging ball 12 needs to be replaced so that it can maintain the seal on the slurry delivery pipe 31. If there is no air pressure leakage at the discharge pipe 51, it indicates that the pigging ball 12 is in good condition and can continue to be used. Traditional pigging systems, being completely open, lack any effective method to detect the wear and tear of the pigging ball 12. In this embodiment, because the pigging ball 12 has a unique structure that seals and isolates the cleaning chamber 11 and the slurry delivery pipe 31 through its spherical surface, it is possible to easily and effectively detect whether the pigging ball 12 is damaged during use.
[0043] Please see Figures 1 to 3In some optional embodiments, the slurry feeding mechanism 40 includes a slurry feeding pipe connected to the slurry delivery pipe 31. A pressure relief assembly 70 is provided on the slurry feeding pipe and connected to the discharge pipe 51. The pressure relief assembly 70 includes a connecting pipe 71 connecting the discharge pipe 51 and the slurry feeding pipe, and a second valve 72 that can be opened and closed is provided on the connecting pipe 71. By opening the second valve 72, the slurry feeding mechanism 40 can release pressure through the discharge pipe 51. It is understood that if there is gas in the pipe before the slurry is introduced, the gas may mix into the slurry, generating bubbles and affecting the coating effect. Pre-venting with the pressure relief assembly 70 can remove excess gas.
[0044] Please see Figure 2 and Figure 3 In some optional embodiments, the feeding mechanism 20 is located above the cleaning chamber 11 to facilitate the introduction of cleaning fluid to clean the pigging ball 12. The discharging mechanism 50 is located below the cleaning chamber 11 to facilitate the discharge of cleaning fluid after cleaning the pigging ball 12. Specifically, gas and / or liquid are introduced into the cleaning chamber 11 through the feeding mechanism 20 to clean the pigging ball 12, and the cleaning gas and / or liquid are discharged out of the cleaning chamber 11 through the discharging mechanism 50. In this embodiment, the feeding mechanism 20 includes a feeding pipe 21, an air intake assembly 22, and a liquid intake assembly 23. The feeding pipe 21 is connected to the cleaning chamber 11, the air intake assembly 22, and the liquid intake assembly 23, respectively. The feeding pipe 21 can be a T-junction, with one end connected to the cleaning chamber 11, the other end connected to the air intake assembly 22, and the third end connected to the liquid intake assembly 23. The air intake assembly 22 is used to introduce gas into the cleaning chamber 11. The air intake assembly 22 is equipped with a third valve 221 that can be opened and closed, which can be used to control the intake or stop the intake. The liquid inlet assembly 23 is used to introduce liquid into the cleaning chamber 11. The liquid can be a cleaning fluid. The liquid inlet assembly 23 is equipped with a fourth valve 231 that can be opened and closed, which can be used to control the intake or stop the intake.
[0045] like Figures 1 to 7As shown, the slurry pipeline ball-pushing device 100 of the present invention includes a cleaning mechanism 10, a feeding mechanism 20, a slurry feeding mechanism 40, a slurry delivery mechanism 30, and a discharge mechanism 50. The cleaning mechanism 10 includes a cleaning chamber 11 and a pigging ball 12. The feeding mechanism 20 provides gas and liquid to the cleaning chamber 11 to clean the pigging ball 12 within the cleaning chamber 11. The pigging ball 12 seals and isolates the cleaning chamber 11 from the slurry delivery mechanism 30, preventing the gas and liquid used for cleaning from entering the slurry delivery mechanism 30. The gas and liquid used to clean the pigging ball 12 are discharged through the discharge mechanism 50, ensuring that the slurry in the slurry delivery mechanism 30 does not mix with the cleaning liquid. The cleaning chamber 11 and the slurry delivery mechanism 30 are sealed together by the pigging ball 12, eliminating the need to close additional valves when cleaning the pigging ball 12. Furthermore, it facilitates the detection of damage to the pigging ball 12, allowing for timely replacement and ensuring better cleaning of the pipeline. Meanwhile, in some cases, after the pigging ball 12 cleans products from certain pipelines, it can be directly cleaned without flushing the pipeline, eliminating the need for additional valves and control procedures to prevent cleaning fluid from entering the slurry delivery mechanism 30. This not only makes operation more convenient but also avoids significant waste of cleaning fluid. The slurry inlet mechanism 40 is used to introduce slurry into the slurry delivery mechanism 30. The slurry delivery mechanism 30 is used to convey the slurry. The outlet mechanism 50 is used to discharge gas and liquid. When the pigging ball 12 is conveyed within the slurry delivery mechanism 30, it can clean the pipeline of the slurry delivery mechanism 30. The conveying of the pigging ball 12 can be achieved by pushing gas / liquid / slurry. The pigging ball 12 in this invention has a built-in sealing function, which can effectively isolate the cleaning chamber 11 from the slurry delivery mechanism 30, making the structure simpler and the operation more convenient.
[0046] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
