Figure 3 A schematic cross-sectional view of an iron remover of an automatic cleaning and high-efficiency iron removal device provided by an exemplary embodiment of the present invention is shown. Figure 4 Shows Figure 3 The partial enlarged structural schematic diagram at A shows that the automatic cleaning and high-efficiency iron removal device includes a bracket 1 and an iron remover 2 installed on the bracket 1, and the iron remover 2 includes: a barrel 21, a bottom of which is connected to a head 22, the bottom of the head 22 is provided with an iron remover liquid inlet 27, and the top is connected to an end cover 24 through a locking assembly 23; a magnetic rod 25, a first end of which is fixed to the bottom of the end cover 24, and a second end of which is inserted into a slurry channel 26 inside the barrel 21, the top of the end cover 24 is connected to the lifting assembly 3, the first end of the slurry channel 26 is connected to the head 22, and the second end of the slurry channel 26 is connected to the iron remover liquid outlet 28 on the upper part of the barrel 21; and a scraper assembly 29, which is arranged at the inner top of the barrel 21, and the annular scraper 291 of the scraper assembly 29 is flexibly wrapped around the outer periphery of the magnetic rod 25.

[0029] In the embodiment of the present application, the automatic cleaning and efficient iron removal device realizes efficient iron removal and automatic cleaning functions through the cooperation of various components. The bracket 1 provides stable support for the iron remover 2. The body 21 and the head 22 of the iron remover 2 constitute a slurry circulation cavity. The iron remover liquid inlet 27 and the iron remover liquid outlet 28 realize the input of iron-containing slurry and the output of clean liquid; the end cover 24 is quickly disassembled and assembled with the body through the locking assembly 23, which is convenient for internal maintenance. The magnetic rod 25 is inserted into the slurry channel 26, and the iron impurities are adsorbed by magnetism. The first end of the magnetic rod 25 is fixed to the bottom of the end cover 24, and the top of the end cover 24 is connected to the lifting assembly 3. The magnetic rod 25 fixed to the bottom of the end cover 24 can be driven up and down by the lifting assembly 3, and the scraper assembly 29 is used to remove the attachments on the surface of the magnetic rod 25; the flexible annular scraper 291 fits tightly to the outer periphery of the magnetic rod, and flexibly scrapes away impurities during the lifting process, avoiding rigid damage and no cleaning dead corners.

[0030] In detail, the scraper assembly 29 includes: a scraper mounting ring 292, which is installed on the inner top of the barrel 21; and a scraper seat 293, which is fixed on the scraper mounting ring 292 and flexibly wraps the annular scraper 291 around the outer periphery of the magnetic rod 25 through a retaining ring 294.

[0031] In the embodiment of the present application, the annular scraper 291 of the scraper assembly 29 uses flexible material to tightly fit the surface of the magnetic rod 25, effectively scraping off the adsorbed ferromagnetic impurities during the lifting process of the magnetic rod 25, avoiding damage to the magnetic rod caused by rigid contact, and ensuring circumferential cleaning without dead ends, thereby improving the automated cleaning efficiency and reliability of the iron removal device and reducing the frequency of manual maintenance.

[0032] Specifically, the locking assembly 23 includes: a turntable 231, which is rotatably mounted on the end cover 24 and driven to rotate by a motor 236; a slide rail 232, which is mounted on the end cover 24 and is slidably connected to a locking block 233; a push rod 234, whose two ends are respectively hinged to the turntable 231 and the locking block 233; and a locking buckle 235, which is mounted on the top of the barrel 21 and is adapted to the locking block 233.

[0033] In the embodiment of the present application, the locking assembly 23 drives the turntable 231 to rotate through the motor 236, and drives the locking block 233 to slide along the slide rail 232 through the push rod 234, and cooperates with the locking buckle 235 on the top of the barrel 21 to realize the automatic locking or loosening of the end cover 24 and the barrel 21. This design can ensure the internal sealing of the iron remover to prevent liquid leakage, and at the same time supports automatic disassembly and assembly, which is convenient for rapid maintenance of internal components such as the magnetic bar 25 and the scraper assembly 29, reducing manual operations and improving equipment maintenance efficiency and operational reliability.

[0034] Furthermore, a positioning sleeve 212 is also provided at the first end of the slurry channel 26, which is used to position the second end of the magnetic rod 25 to ensure the concentricity of the magnetic rod 25 and the slurry channel 26. This design can avoid the uneven distribution of the magnetic field caused by the deflection of the magnetic rod, so that the ferromagnetic impurities are evenly adsorbed in the channel, and the iron removal efficiency is improved; at the same time, the radial shaking of the magnetic rod when it is lifted is reduced, the friction loss with the channel is reduced, and the smoothness of the cleaning action is ensured. Concentric positioning can also optimize the liquid flow path, avoid local eddy currents or blockages caused by the deviation of the magnetic rod, and ensure the long-term stable operation of the device, which is especially suitable for continuous iron removal scenarios of high-concentration slurries.

[0035] Specifically, there are four iron removers 2, namely the first-stage to fourth-stage iron removers 2. A circulation pipeline 4 and a liquid discharge pipeline 5 are arranged below the four iron removers 2. First multi-channel ball valves 6, second multi-channel ball valves 7, third multi-channel ball valves 8, and fourth multi-channel ball valves 9 are respectively arranged corresponding to the lower parts of the four iron removers 2; the first end of the first multi-channel ball valve 6 serves as a ball valve liquid inlet and is connected to an external liquid storage tank, the second end of the first multi-channel ball valve 6 is connected to the iron remover liquid inlet 27 of the first-stage iron remover 2, the third end of the first multi-channel ball valve 6 is connected to the circulation pipeline 4, and the fourth end of the first multi-channel ball valve 6 is connected to the liquid discharge pipeline 5; the first end of the second multi-channel ball valve 7 serves as a ball valve liquid inlet and is connected to the iron remover liquid outlet 28 of the first-stage iron remover 2 through a first connecting pipeline 10, the second end of the second multi-channel ball valve 7 is connected to the iron remover liquid inlet 27 of the second-stage iron remover 2, the third end of the second multi-channel ball valve 7 is connected to the circulation pipeline 4, and the fourth end of the second multi-channel ball valve 7 is connected to the liquid discharge pipeline 5; the first end of the third multi-channel ball valve 8 serves as a ball valve liquid inlet and is connected to the iron remover liquid outlet 28 of the second-stage iron remover 2 through a second connecting pipeline 11, the second end of the third multi-channel ball valve 8 is connected to the iron remover liquid inlet 27 of the third-stage iron remover 2, the third end of the third multi-channel ball valve 8 is connected to the circulation pipeline 4, and the fourth end of the third multi-channel ball valve 8 is connected to the liquid discharge pipeline 5; the first end of the fourth multi-channel ball valve 9 serves as a ball valve liquid inlet and is connected to the iron remover liquid outlet 28 of the third-stage iron remover 2 through a third connecting pipeline 12, the second end of the fourth multi-channel ball valve 9 is connected to the iron remover liquid inlet 27 of the fourth-stage iron remover 2, the third end of the fourth multi-channel ball valve 9 is connected to the circulation pipeline 4, and the fourth end of the fourth multi-channel ball valve 9 is connected to the liquid discharge pipeline 5.

[0036] In the embodiment of the present application, the device is provided with four-stage iron removers 2 (the first to fourth stages) and configured with multi-channel ball valves, achieving efficient iron removal and process optimization through hierarchical series connection and flexible flow path control. The four iron removers 2 form a series link through multi-channel ball valves and connecting pipelines: the liquid outlet 28 of the previous-stage iron remover is connected to the liquid inlet 27 of the next-stage iron remover through a multi-channel ball valve, enabling the slurry to be adsorbed by the multi-stage magnetic rods 25 in sequence, gradually increasing the iron impurity removal rate, and meeting the high-purity treatment requirements.

[0037] More specifically, the first-stage and second-stage iron removers 2 correspond to one lifting assembly 3, and the third-stage and fourth-stage iron removers 2 correspond to one lifting assembly 3. The lifting assembly 3 includes: a cylinder 31, which is installed on the bracket 1; a synchronous lifting frame 32, the middle of which is connected to the telescopic end of the cylinder 31, and both ends of which are respectively connected to the tops of the end caps 24 of the two corresponding iron removers 2 through a plurality of connecting columns 215; and a stroke stop 33, which is installed on the bracket 1 for limiting the stroke of the telescopic end of the cylinder 31.

[0038] In the embodiment of the present application, the lifting assembly 3 adopts a grouped control design. The first and second levels and the third and fourth levels of the iron removers 2 share a lifting assembly 3 respectively. The synchronous lifting frame 32 is driven by the air cylinder 31 to realize the synchronous lifting and lowering of the end caps 24 of the corresponding two groups of iron removers 2, that is, the synchronous lifting and lowering of the magnetic rods 25 fixed to the bottom of the end caps 24. The stroke stop 33 limits the stroke of the air cylinder to ensure the accurate lifting and lowering position of the magnetic rods. In this case, the number of components is reduced, the mechanical structure is simplified, and the maintenance cost is reduced. At the same time, the magnetic rods 25 in the same group are cleaned synchronously with the scraper assembly 29 through synchronous actions, avoiding the complexity of single-stage independent control, improving the automation degree and cleaning efficiency of the iron removal device, and ensuring the coordination and reliability of the multi-stage iron removal process.

[0039] It is worth mentioning that a pressure relief valve 210, a pressure sensor 211, and a cleaning pipeline 213 communicating with the slurry channel 26 are also provided on the upper part of the cylinder body 21. The cleaning pipeline 213 has a cleaning port 214 for adding a cleaning solution. The circulation pipeline 4 has a circulation port 41 communicating with an external liquid storage tank. The drain pipeline 5 has a waste liquid port 51 for draining waste liquid. Casters 13 are installed at the bottom of the bracket 1.

[0040] In the embodiment of the present application, the pressure relief valve 210 on the upper part of the cylinder body 21 cooperates with the pressure sensor 211 to monitor the pressure of the slurry channel in real time, and relieves pressure when overpressure to ensure safety; the cleaning pipeline 213 and the cleaning port 214 are convenient for injecting the cleaning liquid, and cooperate with the scraper assembly to realize deep cleaning of the magnetic rods. The circulation port 41 of the circulation pipeline 4 is connected to an external liquid storage tank to support the circulation treatment of the slurry; the waste liquid port 51 of the drain pipeline 5 is used for discharging waste liquid. The casters 13 at the bottom of the bracket 1 facilitate the movement of the device and improve the installation flexibility. These settings improve the safety monitoring, maintenance convenience, and process adaptation ability of the entire device, meeting the diverse needs of industrial scenarios.

[0041] Next, the working principle of an automatic cleaning and high-efficiency iron removal device involved in the embodiment of the present invention will be described.

[0042] First, please refer to Figures 1 to 4 , when the device is in a normal working state, the slurry is introduced from the first multi-channel ball valve into the liquid inlet of the first-stage iron remover, flows through the slurry channel of the first-stage iron remover, and then is exported from the liquid outlet of the first-stage iron remover. The liquid outlet of the previous-stage iron remover is connected to the liquid inlet of the next-stage iron remover through a multi-channel ball valve, so that the slurry passes through multiple magnetic rods for adsorption in sequence, gradually improving the iron impurity removal rate until it is exported from the liquid outlet of the fourth-stage iron remover to the next process.

[0043] Secondly, please refer to Figure 5, when the device needs to clean the iron remover, the first multi-channel ball valve stops feeding, and the slurry in the iron remover is discharged into the liquid storage tank through the circulation pipeline. After that, the locking mechanism is unlocked driven by the motor, and the magnetic rod is lifted driven by the cylinder of the lifting component. The fixed scraper component scrapes the magnetic substances and slurry attached to the magnetic rod. The waste liquid falls into the head through the slurry channel, and then NMP solution is sprayed in through the cleaning pipeline for cleaning. The cleaning waste liquid is discharged through the drain pipeline. Then, the magnetic rod is reset driven by the cylinder of the lifting component, and the locking mechanism locks the iron remover driven by the motor. Subsequently, slurry can be continuously introduced for iron removal work. (Similarly, the cylinder can be replaced by an electric cylinder, or other mechanisms or devices that can achieve linear motion functions).

[0044] Finally, please refer to Figure 6 , when the device needs to replace the annular scraper, remove the stroke stop block on the cylinder, unlock the long stroke of the cylinder, remove the bolts between the scraper mounting ring of the scraper assembly and the barrel body, separate the scraper mounting ring from the barrel body through the starting screw, and then manually lift the scraper assembly to prevent accidents by placing a scapegoat; Subsequently, start the cylinder to continue lifting, and sequentially remove the bottom positioning sleeve, retaining ring, and scraper seat of the magnetic rod to remove the annular scraper from below the magnetic rod. After replacing the new annular scraper, sequentially install the scraper mounting ring, scraper seat, retaining ring, and positioning sleeve, remove the scapegoat, connect and fix the scraper mounting ring and the barrel body with bolts, and then after the cylinder drives the magnetic rod to reset, reinstall the stroke stop block of the cylinder to complete the replacement of the annular scraper. (Similarly, the scraper assembly can be set in a clamp-on installation method to directly remove the scraper assembly for replacement; or the scraper assembly can be lifted pneumatically or electrically instead of manually).

[0045] In summary, the technical solution of the present application includes a bracket and an iron remover installed on the bracket. The iron remover includes: a barrel body, the bottom of which is connected with a head, the bottom of the head has an iron remover liquid inlet, and its top is connected with an end cover through a locking assembly; a magnetic rod, the first end of which is fixed to the bottom of the end cover, and the second end of which is inserted into the slurry channel inside the barrel body. The top of the end cover is connected to the lifting component. The first end of the slurry channel is communicated with the head, and the second end of the slurry channel is communicated with the iron remover liquid outlet at the upper part of the barrel body; and a scraper assembly, which is arranged at the inner top of the barrel body, and the annular scraper of the scraper assembly flexibly wraps around the outer circumference of the magnetic rod; wherein, a pressure relief valve and a pressure sensor communicated with the slurry channel are also arranged at the upper part of the barrel body. In this case, aiming at the problem that the existing automatic iron removal device needs to pull out the magnetic rod to clean the magnetic rod sleeve, the present application can directly scrape and clean the magnetic substances on the magnetic rod inside the iron remover, realizing the automatic cleaning of the high-efficiency iron remover while ensuring the iron removal effect, and at the same time avoiding slurry pollution and environmental pollution.
