Description

Technical Field

[0001] This application relates to the technical field of steel pipe cleaning equipment, and in particular to a sedimentation tank for steel pipe cleaning. Background Art

[0002] Steel pipe cleaning is an indispensable process in the metal processing industry. The main purpose is to remove oil stains, rust and other impurities on the surface of the steel pipe to ensure the quality and performance of subsequent processing. With the continuous expansion of industrial production scale, the requirements for the cleaning efficiency and effect of steel pipes are also getting higher and higher. To achieve this goal, specially designed cleaning equipment is usually required, and a sedimentation tank is combined to treat the waste liquid generated during the cleaning process. These waste liquids contain a large amount of iron filings and other impurities. If directly discharged without effective treatment, it will not only cause serious environmental pollution, but also lead to waste of valuable resources. Therefore, how to efficiently recycle the useful substances in these waste liquids has become an important issue that needs to be solved urgently.

[0003] Currently, in the design of sedimentation tanks for steel pipe cleaning, common solutions mainly include multi-stage filtration and physical sedimentation. Specifically, in the first-stage sedimentation tank, larger particles of impurities naturally settle to the bottom of the tank by gravity, while smaller suspended solids can be further intercepted by a filter screen. Some systems use means such as mechanical scrapers or flotation methods to help improve the solid-liquid separation effect.

[0004] Regarding the above related technologies, the inventor believes that although the above methods meet the basic requirements to a certain extent, there are still obvious deficiencies in actual applications. First of all, a single filtration or sedimentation method is difficult to completely remove tiny iron filings particles, especially in high-concentration cases, it is easy to occur blockage phenomena, affecting the normal operation of the entire system. At the same time, the simple sedimentation plus overflow filtration efficiency is slow, requiring a lot of time, and some waste water cannot be treated. In view of these problems, this application proposes an improved structure of the sedimentation tank for steel pipe cleaning, aiming to improve the reliability of the overall system. Summary of the Invention

[0005] To solve the above problems, this application provides a sedimentation tank for steel pipe cleaning.

[0006] The sedimentation tank for steel pipe cleaning provided by this application adopts the following technical solutions:

[0007] A sedimentation tank for steel pipe cleaning, comprising a first separation mechanism for removing larger iron filings and impurities; a second separation mechanism including a second sedimentation tank, the second sedimentation tank communicating with the first separation mechanism, a support frame being provided on one side of the second sedimentation tank, a mounting plate being provided on the support frame, a pressing component being provided on the mounting plate, an adsorption component being provided at the transmission end of the pressing component, the adsorption component including an adsorption plate provided at the transmission end of the pressing component, a plurality of adsorption holes being provided on the adsorption plate, and an electromagnet adsorption layer being provided on the inner wall of the adsorption holes; a cleaning mechanism including a first cleaning block provided on the mounting plate, a corrugated pipe being connected below the first cleaning block, a moving plate being provided below the corrugated pipe, a plurality of cleaning components being provided on the moving plate, the cleaning components being capable of inserting into the adsorption holes, a lifting component being connected below the moving plate, the lifting component being capable of driving the moving plate to move in the vertical direction, the mounting plate, the moving plate, the corrugated pipe and the first cleaning block forming a cleaning chamber, an exhaust port being provided on the cleaning chamber, and a check valve being provided in the exhaust port.

[0008] By adopting the above technical solutions, the sedimentation tank for steel pipe cleaning can effectively remove larger iron filings and impurities, ensuring a more efficient subsequent treatment process. Specifically, the first separation mechanism can intercept and collect larger solid particles, preventing these impurities from entering the next stage of the treatment process, enabling the second sedimentation tank to operate smoothly. The adsorption component in the second separation mechanism is ingeniously designed, using the electromagnet adsorption layer to effectively capture smaller metal particles, adsorbing the iron filings on the electromagnet adsorption layer, and improving the cleaning efficiency. At the same time, the pressing component drives the adsorption plate to move up and down in the second sedimentation tank, increasing the adsorption range and being able to more comprehensively adsorb the iron filings in the second sedimentation tank, further enhancing the decontamination ability. The cleaning mechanism is also provided to cooperate with the adsorption plate for adsorption work. When it is necessary to clean the accumulation in the adsorption holes, the moving plate can move vertically through the lifting component, enabling the cleaning components to accurately insert into each adsorption hole, and generating negative pressure when inserted into the adsorption holes to suck the adsorbed iron filings in the adsorption holes into the cleaning chamber, preventing the iron filings from accumulating and blocking the cleaning holes, so that the adsorption plate can continue to work. The gas generated during the entire cleaning process will flow into the cleaning chamber from the exhaust port, and the check valve ensures the air pressure balance in the cleaning chamber, thus maintaining the stable operation of the system. This structure not only simplifies the operation process, but also extends the service life of the equipment and reduces the maintenance cost.

[0009] Preferably, the first separation mechanism includes a first sedimentation tank provided on one side of the second sedimentation tank, a first connecting pipe being provided on one side of the first sedimentation tank, a filter screen being provided on the first connecting pipe, and the first connecting pipe communicating with the second sedimentation tank.

[0010] By adopting the above technical solution, the device can effectively intercept and remove large iron filings and impurities, prevent these impurities from entering the subsequent treatment process, improve the water cleanliness, precipitate the large iron filings that cannot be adsorbed and other impurities, and ensure the stable operation of the system.

[0011] Preferably, a water pump is provided on the first connecting pipe.

[0012] By adopting the above technical solution, it is possible to ensure the effective removal of large iron filings and impurities while improving the cleaning efficiency. The setting of the water pump makes the liquid flow more smoothly. Compared with the traditional overflow filtration, this not only improves the operating efficiency of the entire system, but also prevents a large amount of residual water in the first sedimentation tank from not being transported out, greatly increasing the applicability and working efficiency.

[0013] Preferably, the pressing-down assembly includes a rotating motor provided on the mounting plate, the transmission end of the rotating motor points vertically to the second sedimentation tank, a transmission shaft is provided at the transmission end of the rotating motor, at least one set of mounting grooves is provided on the transmission shaft, the adsorption plate is provided with connecting holes, at least one set of connecting protrusions is provided on the inner wall of the connecting holes, the connecting protrusions are arranged in the mounting grooves, and a threaded groove is further provided on the inner wall of the second sedimentation tank, and the adsorption plate is in screw drive connection with the threaded groove.

[0014] By adopting the above technical solution, the rotating motor drives the transmission shaft to rotate, driving the adsorption plate to spiral down along the threaded groove to a predetermined position in the second sedimentation tank. This can ensure that the adsorption plate accurately reaches the target depth, thereby effectively adsorbing and removing fine iron filings and other impurities in the second sedimentation tank. During the process of the adsorption plate pressing down, water will flow out from the adsorption holes. At this time, the electromagnet adsorption layer on the adsorption plate can attract metal particles, adsorbing the metal chips on the inner wall of the adsorption holes and improving the cleaning efficiency. In addition, the connection structure between the adsorption plate and the transmission shaft is reasonably designed, ensuring the stability and reliability of the adsorption plate during operation. Generally speaking, this design scheme not only improves the adsorption effect, but also simplifies the operation process and improves the working performance of the equipment.

[0015] Preferably, a backflow prevention mechanism is further provided on the adsorption holes. The backflow prevention mechanism includes a connecting rod provided on the mounting plate, a connecting block is provided on the connecting rod, the connecting block can press on the adsorption holes, a backflow prevention hole is provided on the connecting block, a positioning groove is further provided on the connecting block, and a backflow cover assembly is further included.

[0016] By adopting the above technical solution, the anti-backflow mechanism can effectively prevent the iron filings sucked into the cleaning bin from falling back into the sedimentation tank. Specifically, after the cleaning component sucks the iron filings into the cleaning bin, the anti-backflow mechanism presses on the adsorption holes to seal the adsorption holes. This not only improves the recovery efficiency of the iron filings but also avoids secondary pollution.

[0017] Preferably, the backflow cover assembly includes an extension plate provided on the connection block. A first connection seat is provided on the extension plate. A hole cover is hinged on the first connection seat. A hole cover protrusion is provided on the hole cover. The hole cover protrusion can be arranged in the positioning groove. A second connection seat is also hinged on the hole cover. The second connection seat is connected to the moving plate.

[0018] By adopting the above technical solution, the backflow cover assembly can effectively prevent liquid from flowing back into the adsorption holes, ensuring that the substances in the adsorption holes will not be backflushed into the second sedimentation tank during the cleaning process, thus guaranteeing the cleaning effect and the stability of the equipment operation. At the same time, the structural design enables the hole cover to be automatically opened or closed under the action of the moving plate.

[0019] Preferably, the cleaning component includes a cleaning pipe provided on the moving plate. The cleaning pipe is vertically arranged and can be inserted into the adsorption hole. One end of the cleaning pipe pointing to the second sedimentation tank is closed. A number of cleaning holes are evenly arranged on the pipe wall of the cleaning pipe.

[0020] By adopting the above technical solution, the vertically arranged cleaning pipe can be accurately inserted into the adsorption hole to ensure that the cleaning range is fully covered. The design of one end being closed can increase the negative pressure in the cleaning holes, thus more effectively sucking the metal debris into the cleaning bin. The multiple cleaning holes evenly distributed on the pipe wall enable the air flow to act evenly on the inside of the adsorption hole, improving the cleaning efficiency and effect.

[0021] Preferably, the lifting component includes a telescopic rod provided on the pool wall of the second sedimentation tank. One end of the telescopic rod is connected to the second sedimentation tank, and the other end of the telescopic rod is connected to the moving plate.

[0022] By adopting the above technical solution, the telescopic rod, as a part of the lifting component, can achieve precise control of the moving plate in the vertical direction. When cleaning is required, the telescopic rod can drive the moving plate to move up and down, so that the cleaning component can accurately insert into the adsorption holes, effectively removing the residues and impurities in the adsorption holes. This design not only improves the cleaning efficiency, but also avoids the inconvenience and potential safety hazards caused by manual operation. At the same time, the structure of the telescopic rod is simple and reliable, easy to maintain, ensuring the long-term stable operation of the equipment. In addition, the use of the telescopic rod can flexibly adjust the cleaning position to adapt to adsorption holes of different sizes and shapes, enhancing the versatility and applicability of the system. In short, this technical solution effectively improves the overall performance of the sedimentation tank for steel pipe cleaning, ensuring the efficiency and safety of the cleaning process.

[0023] Preferably, it further includes a water storage mechanism. The water storage mechanism includes a third sedimentation tank, and also includes a second connecting pipe arranged at the bottom of the second sedimentation tank, and a switching valve is arranged on the second connecting pipe.

[0024] By adopting the above technical solution, it can not only effectively collect and store the clean water after multi-stage sedimentation, but also control the discharge timing of the water flow through the switching valve to ensure that the water quality meets the reuse standard, reducing water resource waste and improving production efficiency.

[0025] Preferably, a plurality of water outlet pipes are arranged on the third sedimentation tank, and a water outlet pump is arranged on the water outlet pipes.

[0026] By adopting the above technical solution, after multiple cleaning and sedimentation operations, the sedimentation tank for steel pipe cleaning can collect relatively clean water in the third sedimentation tank, and achieve efficient drainage through multiple water outlet pipes and the water outlet pumps thereon, not only improving the utilization rate of water resources, but also effectively reducing production costs.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. Through the synergistic effect of the first separation mechanism and the second separation mechanism, larger iron filings and impurities can be effectively removed. The first separation mechanism uses the principle of gravitational sedimentation to sediment large-particle impurities to the bottom of the tank, while the adsorption component in the second separation mechanism uses an electromagnet adsorption layer to precisely adsorb tiny iron filings, significantly improving the efficiency and thoroughness of waste liquid treatment, and solving the problem that it is difficult to completely remove tiny iron filings by traditional single filtration or sedimentation methods;

[0029] 2. The design of the cleaning mechanism enables the adsorbed iron filings to be efficiently cleaned and discharged. When the moving plate drives the cleaning component to rise, the cleaning component inserts into the adsorption holes, and by applying pressure to the iron filings in the adsorption holes, they are peeled off from the adsorption plate and pushed into the cleaning bin. This avoids the problem of blockage of the adsorption plate caused by long-term operation, ensuring the stability and continuous working ability of the system;

[0030] 3. The anti-backflow mechanism can effectively prevent the iron filings sucked into the cleaning bin from falling back into the sedimentation tank. Specifically, after the cleaning component sucks the iron filings into the cleaning bin, the anti-backflow mechanism presses on the adsorption holes to seal the adsorption holes. This not only improves the recovery efficiency of the iron filings but also avoids secondary pollution. Thus, the processing capacity and efficiency of the overall system are enhanced.

[0037] The following further describes the present application in detail Figures 1-5 with reference to the accompanying drawings.

[0038] A sedimentation tank for steel pipe cleaning provided by an embodiment of the present application, referring to Figure 1 , Figure 2 and Figure 3 , including a first separation mechanism 1 for removing larger iron filings and impurities; a second separation mechanism 2 for separating smaller iron filings. The second separation mechanism 2 includes a second sedimentation tank 201 for storing mixed sewage. The second sedimentation tank 201 is connected to the first separation mechanism 1. After the sewage is preliminarily filtered by the first separation mechanism 1, it enters the second sedimentation tank 201. A support frame 202 is arranged on one side of the second sedimentation tank 201. An installation plate 203 is arranged on the support frame 202. A pressing component 204 is arranged on the installation plate 203. An adsorption component 205 is arranged at the transmission end of the pressing component 204. The pressing component 204 is used to drive the adsorption component 205 thereon to move in the vertical direction to improve the adsorption capacity of the adsorption component 205. A cleaning mechanism 3 is also arranged above the adsorption component 205. The cleaning mechanism 3 is used to clean the iron filings adsorbed on the adsorption component 205.

[0039] During specific operation, first, the sewage after steel pipe cleaning flows into the first precipitation mechanism through external equipment. After preliminary precipitation by the first precipitation mechanism, larger iron filings are removed, and then the water flows into the second precipitation mechanism, specifically into the second sedimentation tank 201. Subsequently, the pressing component 204 above the second sedimentation tank 201 starts to work, driving the adsorption component 205 to move repeatedly in the second sedimentation tank 201, adsorbing the iron filings in the preliminarily treated sewage onto the adsorption component 205. After that, the adsorption component 205 moves to the uppermost position, and then the cleaning mechanism 3 starts to work, sucking the iron filings on the adsorption component 205 into the cleaning mechanism 3, enabling the adsorption component 205 to re-enter the second sedimentation tank 201 for adsorption work. The sedimentation tank for steel pipe cleaning can effectively remove larger iron filings and impurities, ensuring a more efficient subsequent treatment process. Specifically, the first separation mechanism 1 can intercept and collect larger solid particles, preventing these impurities from entering the next stage of the treatment process, enabling the second sedimentation tank 201 to operate smoothly. The cleaning mechanism 3 is also provided to cooperate with the adsorption plate 2051 for adsorption work. When it is necessary to clean the accumulations in the adsorption holes 2052, the moving plate 303 can move vertically through the lifting component, enabling the cleaning component 304 to accurately insert into each adsorption hole 2052. And when inserted into the adsorption hole 2052, a negative pressure is generated to suck the adsorbed iron filings in the adsorption hole 2052 into the cleaning bin 306, preventing the iron filings from accumulating and blocking the cleaning holes 3042, so that the adsorption plate 2051 can continue to work. The gas generated during the entire cleaning process will flow into the cleaning bin 306 from the exhaust port 307, and the one-way valve 308 ensures the air pressure balance in the cleaning bin, thus maintaining the stable operation of the system. This structure not only simplifies the operation process but also extends the service life of the equipment and reduces the maintenance cost. Specifically, the cleaning component 304 includes a cleaning pipe 3041 arranged on the moving plate 303. The cleaning pipe 3041 is vertically arranged and can be inserted into the adsorption hole 2052. The end of the cleaning pipe 3041 pointing to the second sedimentation tank 201 is closed. A number of cleaning holes 3042 are evenly arranged on the pipe wall of the cleaning pipe 3041. The vertically arranged cleaning pipe 3041 can accurately insert into the adsorption hole 2052, ensuring that the cleaning range fully covers. The design of one end being closed can increase the negative pressure in the cleaning hole 3042, thus more effectively sucking the metal debris into the cleaning bin 306. The multiple cleaning holes 3042 evenly distributed on the pipe wall enable the airflow to act evenly on the inside of the adsorption hole 2052, improving the cleaning efficiency and effect.

[0040] Reference Figure 1 , Figure 2 and Figure 3, Specifically, the pressing component 204 includes a rotating motor 2041 disposed on the mounting plate 203. The transmission end of the rotating motor 2041 points vertically towards the second sedimentation tank 201. A transmission shaft 2042 is provided at the transmission end of the rotating motor 2041. At least one set of mounting grooves 2043 is provided on the transmission shaft 2042. A threaded groove 2046 is also provided on the inner wall of the second sedimentation tank 201.

[0041] During specific operation, the rotating motor 2041 rotates, driving the rotating shaft to rotate, and then driving the transmission shaft 2042 connected to the rotating motor 2041 to rotate. Then, the adsorption plate 2051 is driven to rotate through the mounting groove 2043. The adsorption plate 2051 moves up and down through the screw drive connection with the spiral groove. The side of the spiral groove pushes the adsorption plate 2051 placed in the spiral groove to move.

[0042] Reference Figure 1 , Figure 2 And Figure 3 , Specifically, an adsorption component 205 is provided at the transmission end of the pressing component 204. The adsorption component 205 includes an adsorption plate 2051 provided at the transmission end of the pressing component 204. Specifically, the adsorption plate 2051 is provided with a connection hole 2044. At least one set of connection protrusions 2045 is provided on the inner wall of the connection hole 2044. The connection protrusions 2045 are arranged in the mounting groove 2043. The adsorption plate 2051 is in screw drive connection with the threaded groove 2046. A number of adsorption holes 2052 are provided on the adsorption plate 2051. An electromagnet adsorption layer 2053 is provided on the inner wall of the adsorption holes 2052.

[0043] During specific operation, the rotating motor 2041 drives the transmission shaft 2042 to rotate, driving the adsorption plate 2051 to spiral down into the second sedimentation tank 201 along the threaded groove 2046, thereby effectively adsorbing and removing fine iron filings and other impurities in the second sedimentation tank 201. During the downward pressing of the adsorption plate 2051, water flow will pass through the adsorption holes 2052. At this time, the electromagnet adsorption layer 2053 on the adsorption plate 2051 can attract metal particles, adsorbing the metal chips on the inner wall of the adsorption holes 2052 and improving the cleaning efficiency. Generally speaking, the adsorption effect is improved, the operation process is simplified, the working performance of the equipment is enhanced, and the electromagnet adsorption layer 2053 is used to effectively capture smaller metal particles, adsorbing the iron filings on the electromagnet adsorption layer 2053 and improving the cleaning efficiency.

[0044] Reference Figure 1 , Figure 2 And Figure 3, the cleaning mechanism 3 includes a first cleaning block 301 disposed on the mounting plate 203. A bellows 302 is connected below the first cleaning block 301. A moving plate 303 is disposed below the bellows 302. A plurality of cleaning components 304 are provided on the moving plate 303. The cleaning components 304 can be inserted into the adsorption holes 2052. A lifting component is connected below the moving plate 303. The lifting component includes a telescopic rod 305 disposed on the pool wall of the second sedimentation tank 201. The telescopic rod 305 is an electric telescopic rod 305. One end of the telescopic rod 305 is connected to the second sedimentation tank 201, and the other end of the telescopic rod 305 is connected to the moving plate 303, which can achieve precise control of the moving plate 303 in the vertical direction. When cleaning is required, the telescopic rod 305 can drive the moving plate 303 to move up and down, so that the cleaning components 304 can accurately insert into the adsorption holes 2052 to effectively remove the residues and impurities in the adsorption holes 2052.

[0045] Reference Figure 1 , Figure 2 and Figure 3 , the lifting component can drive the moving plate to move in the vertical direction. The mounting plate 203, the moving plate 303, the bellows 302 and the first cleaning block 301 form a cleaning chamber 306. An exhaust port 307 is provided on the cleaning chamber 306. A check valve 308 is provided in the exhaust port 307. As an unillustrated embodiment, a door can be provided in the cleaning chamber 306. After the iron filings are filled, the iron filings in the cleaning chamber 306 are cleaned out manually or by other machinery.

[0046] Reference Figure 3 , Figure 4 and Figure 5 , further includes an anti-backflow mechanism 4 provided on the adsorption holes 2052. The anti-backflow mechanism 4 includes a connecting rod 401 provided on the mounting plate 203. A connecting block 402 is provided on the connecting rod 401. The connecting block 402 can press on the adsorption holes 2052. An anti-backflow hole 403 is provided on the connecting block 402. A positioning groove 404 is also provided on the connecting block 402. Further includes a backflow cover assembly 405. Specifically, the backflow cover assembly 405 includes an extension plate 4051 provided on the connecting block 402. A first connecting seat 4052 is provided on the extension plate 4051. A hole cover 4053 is hinged on the first connecting seat 4052. A hole cover protrusion 4054 is provided on the hole cover 4053. The hole cover protrusion 4054 is made of a flexible material and can be disposed in the positioning groove 404. A second connecting seat 4055 is also hinged on the hole cover 4053. The second connecting seat 4055 is connected to the moving plate 303. As an unillustrated embodiment, a flexible connecting sleeve is provided between the connecting block 402 and the moving plate 303, which can better prevent the backflow of iron filings.

[0047] During specific operation, the lifting component drives the moving plate 303 to move, thereby pulling the corrugated pipe 302, changing the volume of the cleaning bin 306, generating negative pressure in the cleaning bin 306, and then generating suction at the cleaning component 304. After the cleaning component 304 is inserted into the adsorption hole 2052, suction is generated on the iron filings adsorbed on the adsorption hole 2052, and the iron filings are sucked into the cleaning bin 306. The anti-backflow mechanism 4 can effectively prevent the iron filings sucked into the cleaning bin 306 from falling back into the sedimentation tank again. Specifically, after the cleaning component 304 sucks the iron filings into the cleaning bin 306, the anti-backflow mechanism 4 presses on the adsorption hole 2052 to seal the adsorption hole 2052. Then, the moving plate 303 is reset by the lifting component. The lifting component drives the moving plate 303 to move, thereby pulling the corrugated pipe 302, changing the volume of the cleaning bin 306, and the excess gas flows out from the exhaust port 307 on the cleaning bin 306. The one-way valve 308 can prevent the iron filings from flowing out and at the same time prevent the generation of negative pressure. The anti-backflow cover assembly 405 can effectively prevent the liquid from flowing back into the adsorption hole 2052. During specific operation, as the moving plate 303 moves and drives the second connecting seat 4055 to descend, the empty cover rotates with the second connecting seat 4055 as the axis, causing the hole cover 4053 to rotate and no longer press on the adsorption hole 2052. As the moving plate 303 presses down, the hole cover 4053 gradually opens. After the moving plate 303 is reset, the hole cover 4053 presses on the adsorption hole 2052, and at the same time the anti-backflow block presses on the adsorption hole 2052 to prevent the sucked iron filings from being blown out again, causing secondary pollution, and ensuring that the substances in the adsorption hole 2052 will not be backflushed into the second sedimentation tank 201 during the cleaning process, thus ensuring the cleaning effect and the stability of the equipment operation. At the same time, this structural design enables the hole cover 4053 to be automatically opened or closed under the action of the moving plate 303.

[0048] Reference Figure 1 , Figure 2 and Figure 3 Specifically, the first separation mechanism 1 includes a first sedimentation tank 101 arranged on one side of the second sedimentation tank 201. A first connecting pipe 102 is arranged on one side of the first sedimentation tank 101. A filter screen 103 is arranged on the first connecting pipe 102. The first connecting pipe 102 communicates with the second sedimentation tank 201. A water pump 104 is arranged on the first connecting pipe 102.

[0049] During specific operation, the liquid is discharged into the first sedimentation tank 101 by an external institution. Then, through static sedimentation in the first sedimentation tank 101, impurities and some iron filings in the wastewater are removed. Subsequently, the treated wastewater is sent into the second sedimentation tank 201 through the first connecting pipe 102. The filter screen 103 can prevent large iron filings and other impurities from entering the second sedimentation tank 201. This device can effectively intercept and remove larger iron filings and impurities, prevent these impurities from entering the subsequent treatment processes, improve the water quality cleanliness, precipitate the larger iron filings that cannot be adsorbed and other impurities, ensure the stable operation of the system, and can ensure the effective removal of larger iron filings and impurities while improving the cleaning efficiency.

[0050] Reference Figure 1 , Figure 2 and Figure 3 , specifically, it further includes a water storage mechanism 5. The water storage mechanism 5 includes a third sedimentation tank 501, and also includes a second connecting pipe 502 arranged at the bottom of the second sedimentation tank 201. A switching valve 503 is arranged on the second connecting pipe 502.

[0051] During specific operation, after the water in the second sedimentation tank 201 is purified, it is sent into the third sedimentation tank 501 through the second connecting pipe 502. The third sedimentation tank can not only effectively collect and store the clean water after multiple-stage sedimentation, but also control the discharge timing of the water flow through the switching valve 503 to ensure that the water quality meets the reuse standard, reduce water resource waste and improve production efficiency. A number of water outlet pipes 504 are arranged on the third sedimentation tank 501, and a water outlet pump 505 is arranged on the water outlet pipes 504. This sedimentation tank for steel pipe cleaning can collect relatively clean water by using the third sedimentation tank 501 after multiple cleaning and sedimentation operations, and achieve efficient drainage through multiple water outlet pipes 504 and the water outlet pumps 505 thereon, which not only improves the utilization rate of water resources, but also effectively reduces production costs.

[0052] The implementation principle of a sedimentation tank for steel pipe cleaning in an embodiment of this application is as follows: By combining multiple-stage filtration and adsorption, it effectively solves the problem that it is difficult to completely remove tiny iron filings by a single method in a traditional sedimentation tank. Especially the design of the adsorption assembly 205. By using the strong suction force of the electromagnet adsorption layer 2053, it can quickly capture the fine iron filings in the liquid in a short time, greatly improving the purification efficiency. The introduction of the cleaning mechanism 3 further ensures the long-term stable operation of the system. Regularly cleaning the iron filings on the adsorption plate 2051 avoids the blockage problem caused by long-term accumulation and extends the service life of the equipment. Generally speaking, this embodiment not only improves the efficiency and quality of waste liquid treatment, but also has a high degree of automation, is suitable for large-scale industrial production, and has important economic and social values.

[0053] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
