[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a recycling treatment device for ink wastewater, comprising a shell 1, which serves as the external support structure for the entire device and protects the internal components. A drain pipe is installed inside the shell 1 to discharge the filtered wastewater for recycling. A protective cover 2 is installed on the upper part of the shell 1 to prevent external impurities from entering the device and affecting the processing, while also preventing wastewater leakage or gas escape. A conveying pipe 3 is installed through the upper part of the protective cover 2 to transport ink wastewater into the device. A drive motor 5 is installed on the folded edge of the protective cover 2 to provide power for the rotation of the filter barrel 41. A filtration mechanism is installed inside the shell 1, including a filter assembly and an anti-clogging assembly. The filter assembly includes a filter barrel 41, which is rotatably connected to the inner wall of the shell 1. After the wastewater enters the filter barrel 41, during the rotation of the barrel, solid impurities in the wastewater are thrown towards the barrel wall under centrifugal force, while the filtered water flows out through the barrel wall, achieving solid-liquid separation.

[0032] Furthermore, a connecting rod 42 is vertically fixed to the inner wall of the filter barrel 41, connecting the output shaft of the drive motor 5 and the filter barrel 41, transmitting the rotational power of the drive motor 5 to the filter barrel 41. The connection can be quickly disengaged through plugging, facilitating maintenance. The upper part of the connecting rod 42 is plugged into the lower part of the output shaft of the drive motor 5. A guide plate 43 is fixedly connected to the upper surface of the filter barrel 41. Multiple sets of guide plates 43 are arranged around the center point of the filter barrel 41. When the filter barrel 41 rotates, the guide plates 43 rotate with it and squeeze the rollers 49 in the anti-clogging component, driving the moving part 45 and the fixed rod 46 to move, so that the scraper 47 scrapes the inside of the filter barrel 41, ensuring that the filter barrel 41 will not be blocked due to the accumulation of impurities during long-term operation, maintaining continuous filtration. The outer periphery of the guide plate 43 is set as an inclined surface. A fixing part 44 is fixedly installed on the inner wall of the outer shell 1 by bolts, providing a sliding track and support structure for the moving part 45.

[0033] Reference Figure 2 - Figure 4 The anti-clogging component includes a movable part 45, which is slidably connected to the inner wall of the fixed part 44. When subjected to the force of the guide plate 43 pressing the roller 49, the movable part 45 can move up and down within the fixed part 44, thereby driving the fixed rod 46 to move. The fixed rod 46 is fixedly connected to the lower part of the movable part 45. Driven by the movable part 45, the fixed rod 46 enables the scraper 47 to fit tightly against the inner wall of the filter barrel 41, scraping off the impurities attached to the barrel wall, preventing the filter barrel 41 from clogging, and ensuring filtration efficiency. The scraper 47 is fixedly connected to the side of the fixed rod 46 near the filter barrel 41. The scraper 47 is made of silicone material, which has a certain degree of flexibility and wear resistance. Driven by the fixed rod 46, the scraper 47 can effectively scrape off the impurities on the inner wall of the filter barrel 41 without damaging the filter barrel 41, thus extending the service life of the filter barrel 41.

[0034] Furthermore, a roller 49 is provided at the lower part of the movable part 45. The roller 49 can reduce the friction between the movable part 45 and the guide plate 43, so that the guide plate 43 can push the movable part 45 to move more smoothly, ensuring the sensitivity and reliability of the anti-blocking mechanism. The right side of the movable part 45 is elastically connected to the fixed part 44 through a return spring 48. After the squeezing effect of the guide plate 43 on the roller 49 disappears, the return spring 48 can use its own elastic restoring force to pull the movable part 45 back to its original position. A hole is provided on the right side of the movable part 45, and one end of the return spring 48 is placed inside the hole.

[0035] Reference Figure 2 , Figure 3 and Figure 5The outer side of the outer casing 1 is provided with a disassembly and assembly assembly, which includes a fixing block 61. The fixing block 61 is fixedly connected to the left and right sides of the outer casing 1, providing an installation position and sliding track for the limiting rod 62. The limiting rod 62 is slidably connected to the inner wall of the fixing block 61. When maintenance is required inside the device, the limiting rod 62 is pulled to compress the spring, causing the limiting rod 62 to slide out of the insertion hole 64, so that the protective cover 2 can be quickly removed. This facilitates the operator to inspect and clean the internal equipment, improving the maintenance efficiency of the equipment. Multiple sets of limiting rods 62 are provided. On the opposite side of the multiple sets of limiting rods 62, a compression spring 63 is provided to provide elasticity for the limiting rod 62, so that it can be tightly inserted into the insertion hole 64, ensuring the fixing effect of the protective cover 2.

[0036] Furthermore, the inner wall of the protective cover 2 is provided with an insertion hole 64, and the limiting rod 62 is inserted into the inner wall of the insertion hole 64. In cooperation with the limiting rod 62, when the device is running normally, the limiting rod 62 is inserted into the insertion hole 64 to achieve a tight connection between the protective cover 2 and the outer shell 1. During maintenance, the limiting rod 62 is pulled out from the insertion hole 64 to facilitate the disassembly of the protective cover 2. The limiting rod 62 is designed in an L shape to facilitate the operator to pull it. The inner wall of the protective cover 2 is provided with a sealing gasket 7 to increase the sealing between the protective cover 2 and the outer shell 1.

[0037] Working principle: When in use, ink wastewater enters the filter barrel 41 inside the outer shell 1 through the conveying pipe 3 at the top of the protective cover 2. The drive motor 5 is started, and its output shaft drives the connecting rod 42 to rotate, which in turn makes the filter barrel 41 rotate. Under the action of centrifugal force, larger particles of impurities in the wastewater are thrown to the inner wall of the filter barrel 41, realizing solid-liquid separation. The filtered water flows through the wall of the filter barrel 41 to the next processing stage or collection area of ​​the device.

[0038] As the filtration process continues, impurities tend to accumulate on the inner wall of the filter barrel 41. At this time, the rotation of the filter barrel 41 causes multiple sets of guide plates 43 on its upper surface to rotate together. Since the outer periphery of the guide plate 43 is inclined, it will squeeze the roller 49 at the bottom of the moving part 45 during the rotation. After the roller 49 is squeezed, it pushes the moving part 45 to slide upward on the inner wall of the fixed part 44, and the return spring 48 between the right side of the moving part 45 and the fixed part 44 is compressed.

[0039] The moving part 45 drives the lower connected fixed rod 46 to move, so that the silicone scraper 47 on the side of the fixed rod 46 close to the filter barrel 41 fits tightly against the inner wall of the filter barrel 41, and scrapes off the impurities on the barrel wall as the filter barrel 41 rotates.

[0040] When the guide plate 43 stops pressing the roller 49, under the elastic restoring force of the return spring 48, the moving part 45 drives the scraper 47 back to the initial position, ready for the next anti-clogging operation, thereby effectively preventing the filter canister 41 from clogging and maintaining the stability of the filtration efficiency.

[0041] When maintenance is required, the operator pulls the limiting rod 62 in the disassembly assembly on the outside of the outer casing 1, compresses the compression spring 63, and causes the limiting rod 62 to slide out of the insertion hole 64 on the inner wall of the protective cover 2, releasing the fixation of the protective cover 2. At this time, the protective cover 2 can be easily opened to inspect, clean or replace the filter mechanism inside the device.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
