This is an existing technology, so it will not be elaborated here.

[0027] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a collection structure, the collection structure can collect the impurities filtered in the cavity of the processing chamber (20). The collection structure includes: a bottom box (34) and a collection box (37), the bottom box (34) is fixedly connected to the bottom of the processing chamber (20), the collection box (37) is clamped to the wall surface of the bottom box (34), and one side wall surface of the bottom box (34) is in an open state.

[0028] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, there is a middle hole in the cavity of the collection box (37). The top of the collection box (37) is open. The collection box (37) is in the shape of a semi-capsule box. A semi-capsule-shaped notch is penetrated and opened at the center of the arc surface of the collection box (37). The collection structure further includes a through pipe (32), a guiding plate (33), a fixing groove (35) and a through groove (36). The through pipe (32) is fixedly connected to the bottom of the processing chamber (20). The guiding plate (33) is fixedly connected to the wall surface of the through pipe (32). The fixing groove (35) is opened in the cavity of the bottom box (34). The top of the bottom box (34) is also fixedly connected to the bottom of the through pipe (32). The through groove (36) is penetrated and opened at the top of the bottom box (34). The through pipe (32) is in the shape of a hollow circular tube. The top of the through pipe (32) can communicate with the bottom of the cavity in the processing chamber (20). The guiding plates (33) are symmetrically and fixedly connected in the cavity of the through pipe (32). The guiding plates (33) are in the shape of crescent plates. The fixing groove (35) can adapt to the size of the collection box (37). The collection box (37) can enter the fixing groove (35) through the open side wall surface of the bottom box (34). A filtering structure is arranged in the cavity of the processing chamber (20). The filtering structure includes a separation pipe (30), a filtering groove (31), a scraping plate (40) and a stirring rod (41). The separation pipe (30) is rotatably connected to the center of the cavity in the processing chamber (20). The filtering groove (31) is opened on the wall surface of the separation pipe (30). The scraping plate (40) is fixedly connected to the outer wall surface of the separation pipe (30). The stirring rod (41) is fixedly connected to the top of the scraping plate (40).

[0029] During specific use, a valve is installed at the bottom of the separation pipe 30. When in use, the power supply is turned on, and the dissolved and filtered corrosion inhibitor is poured from the feed pipe 22. The corrosion inhibitor will enter the cavity of the processing chamber 20 through the feed pipe 22. At this time, the rotating separation pipe 30 will drive the scraping plate 40 and the stirring rod 41 to stir the corrosion inhibitor to dissolve it. After the stirring is completed, the valve at the bottom of the separation pipe 30 is opened. At this time, the dissolved corrosion inhibitor will enter the cavity of the separation pipe 30 through the filtering groove 31, then move towards the valve at the bottom of the separation pipe 30, and then be discharged from the device along with the valve. The impurities that do not pass through the filtering groove 31 will stay in the cavity of the processing chamber 20, then fall to the inclined surface at the bottom of the cavity in the processing chamber 20 due to gravity, then move along the inclined surface into the cavity of the through pipe 32, and then pass through the space between the symmetric guiding plates 33 in the cavity of the through pipe 32 and fall and accumulate in the cavity of the collection box 37 for collection. If it is necessary to clean the wall surface of the collection box 37, the collection box 37 can be directly pulled out of the fixing groove 35, and then it can be installed in the fixing groove 35 through the open wall surface of the bottom box 34.

[0030] In summary, by setting the collection structure, the filtered impurities can be collected by guiding them after the corrosion inhibitor is filtered, and when cleaning the collected impurities, only the collection box 37 needs to be removed for cleaning. Therefore, compared with the prior art, this solution is more convenient to use.

[0031] AsFigure 2 As shown, the separation tube (30) is in the shape of a hollow cylinder. The separation tube (30) can be driven by a rotating motor (21). The bottom of the separation tube (30) can pass through between the symmetric guide plates (33), and the bottom of the separation tube (30) can also pass through the through groove (36). The filter groove (31) is in the shape of a circular groove. A plurality of filter grooves (31) are evenly arranged on the wall surface of the separation tube (30). Each filter groove (31) can communicate with the cavity inside the separation tube (30). The bottom of the scraper (40) can contact the arc surface at the bottom of the cavity of the treatment chamber (20). The edge of the scraper (40) is in the shape of a slope. The stirring rod (41) is in the shape of a cylinder. The stirring rod (41) and the scraper (40) are symmetrically arranged on both sides of the wall surface of the separation tube (30).

[0032] During specific use, the wall surface of the rotating scraper 40 will contact and scrape the inclined surface at the bottom of the cavity of the treatment chamber 20, scraping up the impurities attached to the bottom of the cavity of the treatment chamber 20. When the scraper 40 rotates, it will drive the stirring rod 41 to stir the corrosion inhibitor in the cavity of the treatment chamber 20.

[0033] In summary, by setting the scraper 40, it is possible to prevent impurities from accumulating in the cavity of the treatment chamber 20, and the stirring rod 41 can enhance the activity of the corrosion inhibitor in the cavity of the treatment chamber 20, improving its dissolution efficiency and filtration efficiency.

[0034] Working principle: A valve is installed at the bottom of the separation tube 30. When in use, turn on the power supply and pour the dissolved and filtered corrosion inhibitor from the feed pipe 22. The corrosion inhibitor will enter the cavity of the treatment chamber 20 through the feed pipe 22. At this time, the rotating separation tube 30 will drive the scraper 40 and the stirring rod 41 to stir the corrosion inhibitor to dissolve it. After the stirring is completed, open the valve at the bottom of the separation tube 30. At this time, the dissolved corrosion inhibitor will enter the cavity of the separation tube 30 through the filter groove 31, then move towards the valve at the bottom of the separation tube 30, and then be discharged from the device through the valve. The impurities that do not pass through the filter groove 31 will stay in the cavity of the treatment chamber 20, then fall to the inclined surface at the bottom of the cavity of the treatment chamber 20 due to gravity, then move along the inclined surface into the cavity of the through pipe 32, and then pass through the space between the symmetric guide plates 33 in the cavity of the through pipe 32 and fall and accumulate in the cavity of the collection box 37 for collection. If it is necessary to clean the wall surface of the collection box 37, just pull out the collection box 37 directly from the fixed groove 35, and then install it by clamping it into the fixed groove 35 through the open wall surface of the bottom box 34.
