Description

Technical Field

[0001] The present invention relates to the technical field of waste acid liquid treatment, and particularly relates to a waste acid liquid treatment device for electrolytic polishing. Background Art

[0002] In a waste acid liquid filtering device with the application number CN202410902912.1, there is a neutralization tank, the top of the neutralization tank is fixedly connected with a filtering cylinder, and the outer wall of the neutralization tank is fixedly connected with a pre-storage tank; a pre-storage mechanism, the pre-storage mechanism includes an electromagnetic plate and a first spring fixedly connected to the top of the pre-storage tank; by setting the pre-storage mechanism, during the process of the filtering cylinder discharging the filtered waste acid liquid into the neutralization cylinder, the unfiltered waste acid liquid can be pre-stored. When it completely enters the neutralization cylinder, the waste acid liquid in the pre-storage tank is then discharged into the filtering cylinder for filtering treatment. The waste acid liquid entering the neutralization cylinder will first be roughly neutralized, and then after the filter mesh plate resets, it will be neutralized again. Through continuous and uninterrupted treatment, the speed of neutralization treatment can be greatly increased, and it can also ensure that the waste acid liquid is pre-filtered before being fully neutralized.

[0003] In the prior art including the above-mentioned patent, when further filtering the initially processed waste acid liquid, existing equipment often faces the serious problem of impurity blockage of the filter membrane. The initially processed waste acid liquid contains various particulate matters, metal ion compounds, and other complex chemical impurities. These impurities are extremely likely to adhere to and accumulate on the surface of the filter membrane during the filtering process. Over time, the filter membrane is blocked, resulting in a sharp drop in the filtration flux and a significant reduction in the filtration efficiency, seriously affecting the progress of waste acid liquid treatment. To maintain the filtering effect, the filter membrane needs to be frequently replaced, which not only increases the treatment cost but also causes waste of resources. The blocked impurities that are not cleaned in time may also trigger chemical reactions, causing chemical corrosion to the filter membrane, further shortening the service life of the filter membrane, and increasing the complexity and cost of equipment maintenance.

Inside the cavity of the housing 50, there is a spiral membrane separation tube 51. One end of the spiral membrane separation tube 51 is connected with a purified water output pipe. An internal cleaner 52 is sleeved outside the spiral membrane separation tube 51. On the inner side wall of the internal cleaner 52, there are a plurality of spray heads arranged in a circular pattern. An adjusting component 53 is arranged on the internal cleaner 52.

[0021] Further, two symmetrically arranged internal limiting rings 502 are arranged inside the housing 50. Sliding grooves matched with the internal cleaner 52 are opened on both of the two internal limiting rings 502. The setting of the internal limiting rings 502 and the sliding grooves can play a role in limiting and guiding the internal cleaner 52, ensuring the stability and accuracy of the internal cleaner 52 during the movement process, and improving the cleaning effect.

[0022] Further, limiting blocks are arranged at both ends of the internal cleaner 52. The limiting blocks are all slidably connected to the inner cavity of the sliding groove. One end of the limiting block is connected with the limiting block through a spring. The cooperation of the limiting block and the spring can not only further ensure the stable sliding of the internal cleaner 52 in the sliding groove, but also the elastic force of the spring can make the internal cleaner 52 generate a certain buffer and elasticity during the movement, better adapting to the cleaning work.

[0023] Furthermore, the nozzles provided on the built-in cleaner 52 are arranged in a circular array, and the directions of the nozzles in two adjacent rows are inclined in opposite directions; a toggle tooth groove is provided on one side of the built-in cleaner 52; the circular array and the arrangement of the nozzles in opposite directions can make the sprayed water or gas cover the surface of the spiral membrane separation tube 51 in all directions, thereby improving the uniformity of cleaning; the toggle tooth groove facilitates the cooperation with the adjustment component 53 to realize the rotation adjustment of the built-in cleaner 52.

[0024] Furthermore, the adjusting component 53 includes a servo motor 531, which is arranged on the outer wall of the shell 50.

[0025] Furthermore, the linkage component 54 includes a first bevel gear 541, which meshes with a fourth bevel gear 535. A threaded adjustment rod 542 is fixedly connected to the center of the first bevel gear 541. A hexagonal sleeve rod 543 is provided at the bottom of the first bevel gear 541, and the threaded adjustment rod 542 passes through the inner cavity of the hexagonal sleeve rod 543. One end of the hexagonal sleeve rod 543 is movably sleeved with a telescopic rotating rod 545, and a threaded hole matching the threaded adjustment rod 542 is provided on the inner bottom wall of the telescopic rotating rod 545. One end of the telescopic rotating rod 545 is connected to a second bevel gear 546, and a third bevel gear 547 meshes with one end of the second bevel gear 546. The third bevel gear 547 is rotatably connected to the outside of the purified water output pipe, and a plurality of turbine blades arranged in a circular array are provided on the outer side wall of the third bevel gear 547. A bearing connecting piece 561 is sleeved on the outer side wall of the telescopic rotating rod 545. One end of the bearing connecting piece 561 is connected to a limiting sliding sleeve 562.

The other end of the limiting sliding sleeve 562 is connected to a rack 564, and a material blocking tooth plate 565 is meshed with one side of the rack 564 through a gear. The material blocking tooth plate 565 is slidably connected to the connecting cover 55. The design of the linkage component 54 is ingenious. Through the transmission cooperation of multiple gears and rods, it can not only drive the turbine blades to accelerate the discharge of waste acid liquid, but also control the water flow rate and water pressure through the expansion and contraction adjustment of the telescopic rotating rod 545, thereby improving the filtration efficiency of the spiral wound membrane separation tube 51.

[0026] Furthermore, a plurality of waste acid liquid ports arranged in a circular array are provided on the connecting cover 55. One end of the connecting cover 55 is detachably installed with a sewage drain pipe 551. A plurality of insertion connecting pipes 552 matching the waste acid liquid ports are provided on one side of the sewage drain pipe 551, and the insertion connecting pipes 552 are communicated with the sewage drain pipe 551. A fixing seat 553 is sleeved on the outside of the sewage drain pipe 551, and one end of the purified water output pipe passes through the top of the fixing seat 553. The cooperation of the circular array of waste acid liquid ports and the insertion connecting pipes 552 facilitates the smooth discharge of waste acid liquid. The detachable installation of the sewage drain pipe 551 is convenient for cleaning and replacement. The fixing seat 553 plays a role in fixing and supporting the purified water output pipe, ensuring the stability of the equipment operation.

[0027] Working principle: First, the pretreated waste acid liquid is input into the precipitation tank 2 through the water inlet pipe for precipitation. Since there are small particulate matters in the pretreated waste acid liquid, during the precipitation process, the particulate matters will slowly precipitate to the bottom of the precipitation tank 2. Filtration process: At this time, the water pump body 3 is started to extract the waste acid liquid in the sedimentation tank 2. After the waste acid liquid enters the filtration mechanism 5 through the conveying pipe 4, it is filtered by the spiral membrane separation tube 51 into reusable purified water and remains in the spiral membrane separation tube 51, and is discharged through the purified water output pipe. During the process, the waste acid liquid is discharged through the sewage drain pipe 551, achieving thorough filtration of impurities in the pretreated waste acid liquid; Cleaning process: First step, the filtered impurities will accumulate on the surface of the spiral membrane separation tube 51. When the accumulation amount is large, it will cause a serious decline in the filtration effect of the spiral membrane separation tube 51, affect the amount of purified water filtered, and reduce the filtration efficiency; At this time, first turn off the water pump body 3, and then connect the input end of the external joint 501 to a cleaning water pump or a cleaning air pump; Second step, the water flow or gas output of the cleaning water pump or the cleaning air pump will be transported to the built-in cleaner 52 through a hose and sprayed onto the surface of the spiral membrane separation tube 51 through multiple nozzles. Regularly use methods such as water flushing, air flushing, or water-air mixed flushing to remove pollutants and sediments on the surface of the spiral membrane separation tube 51; It should be noted that during this process, the servo motor 531 can be started, and the power output shaft of the servo motor 531 drives the driving bar 532 to rotate. The rotation of the driving bar 532 drives the semi-toothed gear 533 to rotate. The intermittent rotation of the semi-toothed gear 533 drives the connecting rod 534 to rotate. With the elastic force of the spring, the connecting rod 534 rotates back and forth to drive the built-in cleaner 52 to rotate back and forth, and the water or gas sprayed by the nozzles can improve the uniformity of the cleaning of the surface of the spiral membrane separation tube 51 and improve the cleaning effect; At the same time, the rotation of the driving bar 532 will drive the fourth bevel gear 535 to rotate simultaneously. The fourth bevel gear 535 meshes with and drives the first bevel gear 541 and the hexagonal sleeve rod 543 to rotate synchronously. The rotation of the hexagonal sleeve rod 543 will drive the telescopic rod 545, the second bevel gear 546, the third bevel gear 547, and multiple turbine blades to rotate. When the turbine blades rotate, they will accelerate the output of the pretreated waste acid liquid in the housing 50 from the sewage drain pipe 551, providing conditions for the nozzles to clean the surface of the spiral membrane separation tube 51; In addition, personnel can use a screwdriver to rotate the threaded adjustment rod 542, and the threaded adjustment rod 542 is threadedly connected with the telescopic rotating rod 545 when it is rotated. In conjunction with the hexagonal sleeve rod 543 limiting the telescopic rotating rod 545, the telescopic rotating rod 545 will be telescopically adjusted. After contraction, the second bevel gear 546 and the third bevel gear 547 can be separated, and the driving of the turbine blades can be stopped; at the same time, when the telescopic rotating rod 545 is telescopically moved, it will drive the rack 564 to move synchronously, and cooperate with the gear meshing to drive the blocking tooth plate 565 to move. Through the movement of the blocking tooth plate 565, part of the plug-in through pipe 552 can be blocked in a linked manner, thereby reducing the water flow rate. When the water flow rate is reduced, the water pressure in the housing 50 will increase. When the pressure value on the outside of the spiral membrane separation tube 51 increases, the water flow will accelerate to penetrate into the inside of the spiral membrane separation tube 51, thereby improving the filtration efficiency of the spiral membrane separation tube 51.

[0028] The above only describes certain exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various different ways without departing from the spirit and scope of the present invention.
