Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic acid injection, and more specifically, to a hydraulic acid injection device for transporting tungstic acid. Background Art

[0002] As a key intermediate in the fields of tungsten smelting and fluorochemical industry, tungstic acid is widely used in the preparation of cemented carbide, catalysts, and nuclear industry shielding materials. In the prior art, the transportation of tungstic acid is mainly achieved through a hydraulic acid injection device, and its core structure includes a hydraulic power unit, a corrosion-resistant liquid storage tank, and a transportation pipeline. During the actual operation of the hydraulic acid injection device, a stable pressure is generated by the hydraulic system to push tungstic acid through the pipeline, and the injection volume can be precisely adjusted in cooperation with the flow control structure to avoid manual contact with corrosive liquids and reduce the risk of leakage.

[0003] During the production process, since tungstic acid is prone to crystallize into solid particles under low temperature or high concentration conditions, it is easy to cause blockage of pipelines or cavities. Moreover, the hard particles formed after the residual acid liquid dries will adhere to the inner wall of the transportation cavity. Traditional cleaning requires disassembling the equipment and flushing with an alkaline solution for neutralization, which is not only complex in operation but also difficult to completely remove the residues in the dead corners.

[0004] In the prior art, for the residual hard particles, there are methods of using an external pulse cleaning device to deal with them, and there are also designs of using an internal mechanical scraper or nozzle to deal with them. However, the internal mechanical scraper or nozzle occupies the cavity space and is very likely to interfere with the normal transportation process during actual use, and the high-pressure corrosion environment accelerates the failure of components. Although the external pulse cleaning device avoids direct contact with the acid liquid, it relies on shutdown disassembly operations and cannot accurately cover the inner wall dead corners. Therefore, there is an urgent need for a non-invasive cleaning structure that can remotely control the cleaning action through an external driving component without occupying the internal space of the transportation cavity. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a hydraulic acid injection device for transporting tungstic acid, aiming to solve the above technical problems.

A first connecting conduit passing through is also fixedly installed on the ring conduit on one side of the second ring frame facing the output end of the second acid liquid delivery sleeve. A sealing through hole for inserting the first connecting conduit is opened on one side of the corrosion-resistant sleeve close to the injection muzzle, and the sealing through hole penetrates through the cavity between the corrosion-resistant sleeve and the first acid liquid delivery sleeve.

[0015] As a further solution of the present invention: The additive delivery module includes several groups of sector-shaped storage cavities fixedly installed on the inner wall of the corrosion-resistant housing. The sector-shaped storage cavities are entirely located in the cavity between the corrosion-resistant housing and the first acid liquid delivery sleeve, and each group of sector-shaped storage cavities is independent. A liquid replenishing valve head is fixedly installed on the outer toroidal surface of each group of sector-shaped storage cavities. A toroidal storage pipe cavity is fixedly installed on the side of the sector-shaped storage cavity facing the output end of the first acid liquid delivery sleeve. An electric control valve is fixedly installed on the outer side surface of the toroidal storage pipe cavity. A conduit passing through the toroidal storage pipe cavity and inserted into the valve body of the electric control valve is installed on the outside of each group of sector-shaped storage cavities. A wire winding cover is fixedly installed on the side surface of the electric control valve. A torsion shaft rod is fixedly installed at the central axis position inside the wire winding cover.

A magnetic absorption liquid passing module is also configured on the end surface of the outer pull conduit clamped in the sealing port.

[0016] As a further solution of the present invention: The magnetic absorption liquid passing module includes a sealing sleeve head fixedly installed on the end surface of the outer pull conduit on the side clamped in the sealing port.

[0018] As a further solution of the present invention: A through port penetrating into the inside of the second acid liquid delivery sleeve is also opened on the side wall of the injection gun muzzle. A one-way control valve is fixedly installed inside the through port. A conduit connected to the output end of the tungstic acid storage unit is fixedly installed through the one-way control valve. An outer turning maintenance plate is movably installed on the outer surface of the corrosion-resistant housing.

[0019] The above technical solutions provided by the present invention have at least the following beneficial effects compared with the prior art:

[0020] (1) This solution achieves external remote control cleaning of impurity particles on the inner wall of the conveying cavity through the coordinated design of the magnetic drive module and the magnetic follower module. Compared with the existing built-in mechanical scraper or external pulse cleaning technology, this solution sets the drive component in the cavity outside the conveying cavity, and uses the electric-controlled magnetic head to adsorb the driven ring to move back and forth and rotate along the inner wall. Combined with the friction of the polishing coating, it can completely remove the attached particles, avoiding the traditional built-in structure from occupying the cavity space and the erosion of the drive components by corrosive media. At the same time, the magnetic drive module is linked to the servo motor through a threaded rod to accurately control the cleaning path and force, solving the defect that the external cleaning equipment relies on shutdown operation and cannot cover dead corners.

[0021] (2) By integrating the additive delivery module, the chelating agent, neutralizing agent and deionized water are injected in stages to achieve the synergistic effect of chemical dissolution and mechanical cleaning. The modularly designed fan-shaped storage chamber independently stores three types of reagents. The injection sequence and flow rate are dynamically adjusted by the electric control valve and the external pull-out catheter to ensure that the cleaning agent accurately covers the dead corners of the inner wall, forming a closed-loop cleaning process. Compared with traditional single alkaline flushing or manual disassembly cleaning, this solution will improve the cleaning efficiency and avoid secondary corrosion of chemical reagents and equipment materials, and is suitable for continuous production needs in high-corrosion environments in the fluorine chemical industry.

[0022] (3) Through the magnetic suction and fluid flow module and the rotatable sleeve structure, the present invention further optimizes the sealing and maintenance convenience of the cleaning agent delivery. The magnetic suction and fluid flow module uses a double sealing design of a third electrically controlled magnetic suction head and an inserted through tube to ensure zero leakage when the external pull-out catheter is connected to the cleaning unit. At the same time, the reset rod and the sealing block are automatically closed after disconnection to prevent acid reverse seepage. In addition, the corrosion-resistant casing's flip-out maintenance plate and quick-release fan-shaped storage chamber design support online fluid replenishment and component replacement, reducing downtime for maintenance. Compared with the complicated pipeline disassembly process in the prior art, this design improves maintenance efficiency and extends the service life of key components.

[0043] As shown in the figure, in order to clearly implement the structure of the embodiments of the present invention, specific structures and devices are marked in the figure, but this is only for schematic needs and is not intended to limit the present invention to this specific structure, device and environment. According to specific needs, those of ordinary skill in the art can adjust or modify these devices and environments. Detailed implementation manners

[0044] The following describes in detail a hydraulic acid injection device for tungsten acid transportation provided by the present invention in combination with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. Those skilled in the art in some well-known technical fields can also implement them in other alternative ways; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0045] As Figures 1 to 10 shown, an embodiment of the present invention provides a hydraulic acid injection device for tungsten acid transportation, including an assembly bracket 1 and a hydraulic power unit 2 and a tungsten acid storage unit 5 assembled on the side of the assembly bracket 1. An acid liquid transportation unit 3 is arranged on the outer surface of the hydraulic power unit 2. The acid liquid transportation unit 3 includes a corrosion-resistant housing 31. A concentric first acid liquid transportation sleeve 6 is movably installed inside the corrosion-resistant housing 31. A concentric second acid liquid transportation sleeve 7 is fixedly installed inside the first acid liquid transportation sleeve 6. There is a cavity between the corrosion-resistant housing 31 and the first acid liquid transportation sleeve 6, and an additive transportation module 9 is arranged in the cavity. There is also a cavity between the first acid liquid transportation sleeve 6 and the second acid liquid transportation sleeve 7, and a magnetic suction drive module 10 is arranged in the cavity;

[0046] The output end of the hydraulic power unit 2 is fixedly installed with a hydraulic push plate 8 that is hermetically extended into the second acid liquid transportation sleeve 7 for hydraulic acid injection. A magnetic suction driven module 11 that is adsorbed corresponding to the magnetic suction drive module 10 is also arranged inside the second acid liquid transportation sleeve 7 in front of the pushing end of the hydraulic push plate 8;

[0047] Among them, the magnetic attraction driven module 11 includes a second circular ring frame 111 and driven rings 114 movably sleeved on both sides of the second circular ring frame 111. The magnetic attraction driving module 10 adsorbs the second circular ring frame 111 to adhere to the inner wall of the second acid liquid delivery casing 7 and reciprocates, and drives the driven rings 114 to rotate reciprocally to rub particulate impurities.

[0048] To solve the problem that impurities particles on the inner wall of the acid injection cavity of the existing acid injection device cannot be remotely controlled and cleaned by an external driving component, the above technical solution is now adopted to solve the problem. The above technical solution mainly consists of an assembly bracket 1, a hydraulic power unit 2, an acid liquid delivery unit 3, a first acid liquid delivery casing 6, a second acid liquid delivery casing 7, an additive delivery module 9, a magnetic attraction driving module 10, and a magnetic attraction driven module 11. The assembly bracket 1 serves as the main support structure of the device and sleeves each component. During use, several universal wheels can be optionally installed to improve the smoothness of the device during use. The hydraulic power unit 2 serves as the main driving unit for acid injection of the device, including structures such as pressure driving and flow control. During use, a stable pressure is generated through the hydraulic system to push tungstic acid through the pipeline, and the injection volume is precisely adjusted by a micro-liter precision adjuster, which is an inherent structure for precision acid injection in the prior art. The acid liquid delivery unit 3 mainly includes a corrosion-resistant casing 31, which is integrally installed on the outer surface of the hydraulic acid injection pump of the hydraulic power unit 2. A concentric first acid liquid delivery casing 6 and a second acid liquid delivery casing 7 are installed inside. Three groups of cavities are formed in sequence from the outside to the inside through the first acid liquid delivery casing 6 and the second acid liquid delivery casing 7. The first group of cavities is arranged between the corrosion-resistant casing 31 and the first acid liquid delivery casing 6, and the additive delivery module 9 is configured inside this cavity. The second group of cavities is arranged between the first acid liquid delivery casing 6 and the second acid liquid delivery casing 7, and the magnetic attraction driving module 10 is configured inside this cavity. The third group of cavities is arranged inside the second acid liquid delivery casing 7, and the magnetic attraction driven module 11 corresponding to the adsorption of the magnetic attraction driving module 10 is configured in this cavity. Moreover, the hydraulic output end of the hydraulic power unit 2 also extends into this cavity, and the hydraulic push plate 8 at the output end pushes out the acid liquid in this cavity.

[0049] The magnetic - driven follower module 11 disposed inside the second acid - liquid delivery sleeve 7, as the unit for cleaning particulate impurities inside the second acid - liquid delivery sleeve 7 in the device, mainly includes a second circular - ring frame 111 and follower rings 114 movably sleeved on both sides of the second circular - ring frame 111. The second circular - ring frame 111 is used to drive the whole structure to reciprocate inside the second acid - liquid delivery sleeve 7. On the one hand, the two follower rings 114 can scrape and clean the inner wall of the second acid - liquid delivery sleeve 7 during the reciprocating movement of the second circular - ring frame 111. On the other hand, they are for movable assembly. Under the adsorption and driving action of the outer magnetic - driven driving module 10, they can also reciprocally rotate, further improving the efficiency of scraping particulate impurities. The magnetic - driven driving module 10, which is the structure for driving the device to clean, is sleeved in the cavity between the first acid - liquid delivery sleeve 6 and the second acid - liquid delivery sleeve 7, separating the driving components and achieving the effect of remotely controlling the cleaning of impurity particles on the inner wall.

[0050] As Figures 1 to 10 shown, the corrosion - resistant housing 31 is integrally and fixedly installed on the outer surface of the output end of the hydraulic power unit 2. And on the side of the corrosion - resistant housing 31 close to the outer surface of the hydraulic power unit 2, an outward - expanding cavity 32 is also fixedly installed. A first servo - motor 33 is fixedly installed in the outward - expanding cavity 32. A gear - sleeve head 34 is fixedly installed on the output end of the first servo - motor 33. A second gear - ring 15 corresponding to the engagement with the gear - sleeve head 34 is fixedly installed on the outer circular surface of the first acid - liquid delivery sleeve 6. A third gear - ring 16 is fixedly installed on the inner circular surface of the first acid - liquid delivery sleeve 6. An injection nozzle 4 is fixedly installed on the output end of the second acid - liquid delivery sleeve 7. A second servo - motor 12 is fixedly installed on the side wall of the injection nozzle 4. A threaded rod 18 is fixedly installed on the output end of the second servo - motor 12.

[0051] Among them, the purpose of configuring the outward - expanding cavity 32 is to reserve a space for the operation of the first servo - motor 33, so that the gear - sleeve head 34 at the output end of the first servo - motor 33 can stably drive the second gear - ring 15 on the outer circular surface of the first acid - liquid delivery sleeve 6 to rotate in this space. Also, because the first acid - liquid delivery sleeve 6 is movably installed inside the corrosion - resistant housing 31, during the operation of the output end of the first servo - motor 33, it can drive the first acid - liquid delivery sleeve 6 to rotate synchronously. The injection nozzle 4 configured at the output end of the above - mentioned second acid - liquid delivery sleeve 7 is a connection valve - head structure in the prior art, which is used to stably transport the acid - liquid reagent in the second acid - liquid delivery sleeve 7 to the target device.

[0052] As Figures 1 to 10As shown, a groove opening 17 for the threaded rod 18 to penetrate is provided on the outer circular ring surface of the second acid liquid delivery sleeve 7. The magnetic attraction driving module 10 includes a first circular ring frame 101 movably installed on the outer circular ring surface of the second acid liquid delivery sleeve 7. A nut sleeve opening 103 that is fixedly installed on the inner circular ring surface of the first circular ring frame 101 and slidably sleeved in the groove opening 17 and meshes with the threaded rod 18 is provided. At a position on the inner circular ring surface of the first circular ring frame 101 opposite to the nut sleeve opening 103, an embedded first electrically controlled magnetic head 102 is also fixedly installed. The magnetic attraction end of the first electrically controlled magnetic head 102 is closely attached to the outer circular ring surface of the second acid liquid delivery sleeve 7. First circular ring notches 104 are provided at both end positions on the outer circular ring surface of the first circular ring frame 101.

[0053] Among them, the configured second acid liquid delivery sleeve 7 is fixedly installed inside the corrosion-resistant sleeve 31, and a groove opening 17 for the threaded rod 18 to penetrate is provided on the outer circular ring surface of the second acid liquid delivery sleeve 7. The first circular ring frame 101 is slidably sleeved on the outer circular ring surface of the second acid liquid delivery sleeve 7 through the groove opening 17. During the rotation of the threaded rod 18 at the output end of the second servo motor 12 on the injection gun nozzle 4, the engaged first circular ring frame 101 can be driven to reciprocate along the groove opening 17 on the outer circular ring surface of the second acid liquid delivery sleeve 7, thereby controlling the reciprocating movement of the magnetic attraction driving module 10.

[0054] As Figures 1 to 10 As shown, the magnetic attraction driving module 10 further includes an outer circular ring sleeve 105 movably installed on the outer circular ring of the first circular ring frame 101. A convex buckle block 106 that is fixedly installed on the inner circular ring edge of the outer circular ring sleeve 105 and is fitted into the first circular ring notch 104 is provided. Extension side plates 107 are fixedly installed on both side walls of the outer circular ring sleeve 105, and second electrically controlled magnetic heads 108 are fixedly installed on the outer surfaces of the extension side plates 107. The magnetic attraction ends of the second electrically controlled magnetic heads 108 are closely attached to the outer circular ring surface of the second acid liquid delivery sleeve 7. A first gear ring 109 that is sleeved with the third gear ring 16 is fixedly installed on the outer circular ring surface of the outer circular ring sleeve 105.

[0055] Among them, the configured second electrically controlled magnetic head 108 is a device in the prior art that can electrically control the magnetic attraction state of its magnetic attraction end face and can turn on or change its magnetic attraction state.

[0056] As Figures 1 to 10As shown, the magnetic adsorption driven module 11 further includes a second circular ring notch 112 formed on the side surface of the second circular ring frame 111. The second circular ring notch 112 is integrally in a non-closed loop C shape, and a communicating cavity rod 113 is movably inserted and installed through the second circular ring notch 112. Driven rings 114 are fixedly installed on both sides of the communicating cavity rod 113. Grinding coatings 117 that fit the inner circular ring wall of the second acid liquid delivery sleeve 7 are fixedly installed on the outer circular ring surfaces of the driven rings 114. The grinding coatings 117 are also in a non-closed loop C shape, and corresponding magnetic blocks 1110 are fixedly installed at the non-closed positions of the grinding coatings 117 to be adsorbed by the second electric control magnetic heads 108 on the same side.

[0057] As Figures 1 to 10 shown, circular ring conduits 116 are fixedly installed inside the driven rings 114. A plurality of auxiliary liquid injection branch pipes 118 passing through the surface of the grinding coating 117 are communicated with the outer circular rings of the circular ring conduits 116. A second connecting conduit 119 that is communicated is fixedly connected between the circular ring conduits 116 on both sides of the second circular ring frame 111 through the inner cavity of the communicating cavity rod 113. A first connecting conduit 115 that penetrates out is also fixedly installed on the circular ring conduit 116 on the side of the outer side of the second circular ring frame 111 facing the output end of the second acid liquid delivery sleeve 7. A sealing through port 14 for inserting the first connecting conduit 115 is formed on the side of the corrosion-resistant sleeve 31 close to the injection muzzle 4. The sealing through port 14 penetrates through the cavity between the corrosion-resistant sleeve 31 and the first acid liquid delivery sleeve 6.

[0058] As Figures 1 to 10 shown, the additive delivery module 9 includes a plurality of groups of sector-shaped storage cavities 91 fixedly installed on the inner wall of the corrosion-resistant sleeve 31. The sector-shaped storage cavities 91 are integrally located in the cavity between the corrosion-resistant sleeve 31 and the first acid liquid delivery sleeve 6. Each group of sector-shaped storage cavities 91 is independent of each other. Liquid replenishing valve heads 92 are fixedly installed on the outer circular ring surfaces of each group of sector-shaped storage cavities 91. A circular ring storage tube cavity 93 is fixedly installed on the side of the sector-shaped storage cavity 91 facing the output end of the first acid liquid delivery sleeve 6. An electric control valve 94 is fixedly installed on the outer side surface of the circular ring storage tube cavity 93. A conduit that penetrates into the valve body of the electric control valve 94 through the circular ring storage tube cavity 93 is installed on the outer side of each group of sector-shaped storage cavities 91. A winding cover 95 is fixedly installed on the side surface of the electric control valve 94. A torsion shaft rod 96 is fixedly installed at the central axis position inside the winding cover 95. An outer pulling conduit 97 is wound and installed on the torsion shaft rod 96. One side of the outer pulling conduit 97 is connected to the output end of the electric control valve 94, and the other side penetrates out of the winding cover 95 and is hermetically clamped in the sealing through port 14. A magnetic adsorption liquid passing module 19 is also configured on the end surface of the outer pulling conduit 97 clamped in the sealing through port 14.

[0059] Among them, the configured additive delivery module 9 is used to store additives, because tungstic acid is easy to crystallize into hard particles under low temperature or high concentration conditions, and adhere to the inner wall of the cavity or pipe. It is difficult to completely remove it by physical cleaning, and the tungstic acid after drying may be converted into insoluble substances such as tungsten oxide, which requires chemical dissolution. Therefore, in order to improve the efficiency of the cleaning end during the cleaning process, an additive delivery module 9 is required. The additive delivery module 9 is a circular structure composed of three groups of fan-shaped storage chambers 91. The three groups of fan-shaped storage chambers 91 can store neutralizers, complexing agents and deionized water respectively. The neutralizer can be an alkaline solution, such as 5% sodium carbonate or sodium hydroxide solution, to neutralize residual tungstic acid and reduce corrosiveness, and the complexing agent can be selected. Citric acid or EDTA is selected to form a soluble complex citric acid complex with tungstate to dissolve the crystallized tungstate particles and prevent secondary deposition, and deionized water is used to rinse the neutralized waste liquid and residual reagents. During the working process, the reagent injection sequence can be as follows: injecting the complexing agent to dissolve the crystals, injecting the neutralizing agent to neutralize the acidity, and then rinsing with deionized water. Therefore, the three groups of fan-shaped storage chambers 91 are independent of each other, and are all equipped with conduits for outward output. Moreover, the three conduits are arranged in a circular ring from the annular storage tube cavity 93 to the valve body of the electric control valve 94. The electric control valve 94 is an electric valve structure in the prior art that can control the three branch conduits, so that the three groups of fan-shaped storage chambers 91 can discharge liquid outward in sequence according to the corresponding order.

[0060] Because the magnetic driven module 11 is used as a cleaning end and is arranged inside through the second acid delivery sleeve 7, and because tungstic acid is relatively corrosive, in order to ensure the delivery stability of the auxiliary added cleaning agent, its three sets of fan-shaped storage chambers 91 are integrally arranged on the outside of the first acid delivery sleeve 6, and only penetrate into the sealed port 14 through the external pull-out catheter 97, so that the first connecting catheter 115 in the subsequent magnetic driven module 11 can be connected to the external pull-out catheter 97, and then the wound external pull-out catheter 97 can be pulled out for use after forming an integrated structure with the external pull-out catheter 97, so as to meet the reciprocating and rotating cleaning needs of the magnetic driven module 11. The winding cover 95 is configured with a torsion shaft 96 at the axial position, and the torsion shaft 96 is used to reset the outer pull tube 97. In the absence of external force, the outer pull tube 97 can be stably and sealed in the sealing port 14. When the first connecting tube 115 in the subsequent magnetic follower module 11 is connected to the outer pull tube 97 to pull it out, the outer pull tube 97 can also be pulled out. When there is no pulling force on the outer end of the outer pull tube 97, the outer pull tube 97 can be pulled back into the sealing port 14 under the reset action of the torsion shaft 96 to complete the reset work.

[0061] In summary, the specific working process of the configured magnetic attraction driven module 11 is as follows:

[0062] First, tungstic acid is injected into the tungstic acid storage unit 5, and flows through the conduit to the position of the one-way control valve 13 on the injection muzzle 4, and the one-way control valve 13 is opened to allow the tungstic acid to be directly injected into the second acid liquid delivery sleeve 7, and then the tungstic acid injected into the second acid liquid delivery sleeve 7 is pushed out through the hydraulic push disk 8 at the output end of the hydraulic power unit 2, and finally stably injected into the target container through the injection muzzle 4. During the hydraulic injection process, the one-way control valve 13 must be kept in a closed state to avoid tungstic acid backflow.

[0063] Then, after the second acid liquid delivery sleeve 7 has been injected for a long time, due to the characteristics of tungstic acid, particulate impurities will be formed on the inner wall of the second acid liquid delivery sleeve 7, which needs to be cleaned by the magnetic driven module 11. During the cleaning process, the hydraulic push disk 8 needs to be retracted, the second servo motor 12 needs to be turned on, and the threaded rod 18 at the output end of the second servo motor 12 is meshed with the nut sleeve 103. During the rotation of the threaded rod 18, the first annular frame 101 can be moved along the groove 17 on the side wall of the second acid liquid delivery sleeve 7 for the threaded rod 18 to rotate. During the movement, the first annular frame 101 can be controlled by controlling the rotation direction of the threaded rod 18 at the output end of the second servo motor 12. The circular frame 101 reciprocates along the outer surface of the second acid liquid delivery sleeve 7. Because the inner wall of the first circular frame 101 is provided with a first electrically controlled magnetic suction head 102 adsorbed with the second circular frame 111, it is only necessary to use the first electrically controlled magnetic suction head 102 to tightly adsorb the second circular frame 111 across the second acid liquid delivery sleeve 7. In the process of the reciprocating movement of the first circular frame 101, the second circular frame 111 can be driven to reciprocate on the inner wall of the second acid liquid delivery sleeve 7, and then the inner wall of the second acid liquid delivery sleeve 7 is polished by the polishing coating 117 on the outer surface of the driven ring 114 on both sides of the second circular frame 111 to clean the attached dirt and foreign particles.

[0064] Then, during the process that the first ring frame 101 reciprocates to drive the driven ring 114 for grinding and cleaning, the first servo motor 33 can be turned on. The gear socket 34 at the output end of the first servo motor 33 drives the engaged second gear ring 15 to rotate, so that the first acid liquid delivery sleeve 6 rotates synchronously. A third gear ring 16 meshing with the first gear ring 109 is also arranged on the inner wall of the first acid liquid delivery sleeve 6. Therefore, during the rotation of the first acid liquid delivery sleeve 6, the first gear ring 109 will be driven to rotate. The first gear ring 109 and the outer ring housing 105 are of an integral structure and are integrally and movably installed on the outer ring surface of the first ring frame 101. Second electric control magnetic heads 108 are fixedly installed on both side edges of the outer ring housing 105, and the second electric control magnetic heads 108 are tightly adsorbed corresponding to the magnetic blocks 1110 on the driven ring 114 on the inner wall of the second acid liquid delivery sleeve 7 through their adsorption ends. Therefore, after the first servo motor 33 is turned on to drive the gear socket 34 at its output end to rotate, the driven rings 114 on both sides of the second ring frame 111 can be driven to rotate, and the grinding coating 117 on the outer surface of the driven ring 114 is controlled to fit the inner wall of the second acid liquid delivery sleeve 7 for rotary cleaning. Since the second ring slot 112 on the second ring frame 111 is in an unclosed state, during the driving process, the outer ring housing 105 does not rotate 360 degrees, but rotates adaptively to the slot of the second ring slot 112, that is, the communicating cavity rod 113 reciprocates and touches the bottom inside the slot of the second ring slot 112 to ensure the stable operation of the device.

[0065] Finally, after the initial grinding and cleaning are completed, the rotation of the outer ring sleeve 105 drives the driven rings 114 on both sides of the second ring frame 111 to reset, so that the connecting cavity rod 113 returns to the outermost position in the second ring notch 112. At this time, the first connecting conduit 115 on the outer driven ring 114 of the second ring frame 111 is facing the sealing port 14. At this time, the first servo motor 33 is turned off, and only the threaded rod 18 at the output end of the second servo motor 12 drives the first ring frame 101 to move straight. Its first connecting conduit 115 can be inserted into the interior of the sealing port 14. After being connected to one end of the outer pulling conduit 97 inside the sealing port 14 through the magnetic absorption liquid delivery module 19 to form an integrated structure, the threaded rod 18 at the output end of the second servo motor 12 can be rotated reciprocally again, so that the magnetic absorption driving module 10 drives the magnetic absorption driven module 11 to polish and clean again along the interior of the second acid solution delivery sleeve 7, and synchronously control the driven ring 114 to rotate reciprocally to increase the polishing strength. Because the first connecting conduit 115 is connected to the outer pulling conduit 97 at this time, the auxiliary reagent in different sector storage cavities 91 can be extracted through the electric control valve 94 into the ring conduits 116 of the driven rings 114 on both sides, and then shunted to the outer end surface of the polishing coating 117 through the auxiliary liquid injection branch pipes 118 on the ring conduits 116, which is liquid preparation and polishing. The injection order of the auxiliary reagent is as described above. After multiple multi-angle polishing and cleaning with the combined reagent, finally, the waste liquid can be discharged together by the hydraulic push plate 8 at the output end of the hydraulic power unit 2.

[0066] As Figures 1 to 10 shown, the magnetic absorption liquid delivery module 19 includes a sealing sleeve head 191 fixedly installed on one side end face of the outer pulling conduit 97 stuck to the sealing port 14. A third electric control magnetic head 192 is fixedly installed on the outer edge face of the sealing sleeve head 191. A first insertion port 193 is opened inside the open end of the sealing sleeve head 191. A plurality of groups of cavities are opened on the outer circular ring edge of the first insertion port 193, and a reset rod 194 is fixedly installed in each group of cavities. A limiting notch 195 is opened on the side of each group of cavities. A U-shaped rod 196 slidably stuck in the limiting notch 195 on the same side is fixedly installed on the reset end of the reset rod 194, and a first sealing plug block 197 sealing the first insertion port 193 is fixedly installed through the U-shaped rod 196 on each side. A second insertion port 198 is also opened inside the sealing sleeve head 191 close to the first insertion port 193.

[0067] As Figures 1 to 10As shown, the magnetic attraction liquid conduction module 19 further includes a metal adsorption ring 199 fixedly installed on the outer side surface of the first connection conduit 115. An insertion through-tube 1911 is fixedly installed on the outer end surface of the metal adsorption ring 199. A second sealing plug 1910 is fixedly installed on the outer circumferential surface of the insertion through-tube 1911. A plurality of liquid leakage ports 1912 are arranged in a circumferential pattern on the extending end of the insertion through-tube 1911.

[0068] Among them, the configured magnetic attraction liquid conduction module 19, as described above, functions to connect the first connection conduit 115 and the outer pull conduit 97. Specifically:

[0069] First, the outer pull conduit 97 is hermetically sealed in the sealing through-port 14 through the sealing sleeve head 191. After the first connection conduit 115 approaches, the insertion through-tube 1911 on the first connection conduit 115 will first insert into the first insertion port 193 and push the first sealing plug 197 in the first insertion port 193 to move towards the second insertion port 198. The inner port radius of the second insertion port 198 is larger than that of the first insertion port 193.

[0070] Then, as the first sealing plug 197 is further pushed in, the second sealing plug 1910 on the insertion through-tube 1911 will insert into the first insertion port 193 and block the inside of the first insertion port 193. And the metal adsorption ring 199 will fit on the adsorption end surface of the third electric control magnetic head 192 on the outer surface of the sealing sleeve head 191. At this time, turn on the magnetic attraction end of the third electric control magnetic head 192 to firmly adsorb the metal adsorption ring 199. In this state, the insertion through-tube 1911 is also completely inserted into the first insertion port 193, causing the first sealing plug 197 to be entirely pushed into the second insertion port 198.

[0071] Finally, after the insertion through-tube 1911 drives the first sealing plug 197 to extend into the second insertion port 198, the liquid leakage ports 1912 on the insertion through-tube 1911 will also extend into the second insertion port 198. At this time, only need to open one end of the electric control valve 94, and the reagent in the outer pull conduit 97 can flow into the liquid leakage ports 1912 of the insertion through-tube 1911 through the second insertion port 198 and enter the first connection conduit 115 through the liquid leakage ports 1912, thus connecting the entire conveying path.

[0072] The configured reset rod 194 is a telescopic rod structure controlled by a reset spring in the prior art. After the insertion through-tube 1911 withdraws, under the drive of the reset force, the first sealing plug 197 will reset, restoring the sealing state of the sealing through-port 14.

[0073] As Figures 1 to 10As shown, a through port penetrating into the interior of the second acid solution delivery sleeve 7 is further provided on the side wall of the injection nozzle 4, and a one-way control valve 13 is fixedly installed in the through port. A conduit connected to the output end of the tungstic acid storage unit 5 is also fixedly installed through the one-way control valve 13. An outward-turning maintenance plate 35 is movably installed on the outer surface of the corrosion-resistant housing 31.

[0074] Among them, the configured one-way control valve 13 is an electric control valve structure capable of one-way flow in the prior art, which is used to control the tungstic acid stored in the tungstic acid storage unit 5 to supplement the second acid solution delivery sleeve 7. The outward-turning maintenance plate 35 is a guard plate structure that can be opened outward, which is used to open the corrosion-resistant housing 31 to facilitate supplementing reagents to the fan-shaped storage cavity 91 through the liquid filling valve head 92 in real time.
