[0028] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated herein can be arranged and designed in various different configurations.

[0029] Embodiment 1

[0030] As Figures 1-3 shown, a pretreatment device for a circulating water treatment device includes a filter cylinder 1. The top of the filter cylinder 1 is open, and water enters from the top. Two semi-circular support plates A11 are symmetrically arranged front and back and are welded to the top of the filter cylinder 1. A water outlet 12 is provided at the bottom of the filter cylinder 1 for discharging water. A sundry cylinder 3 with the same height as the filter cylinder 1 and the same top opening diameter is welded to the outer wall on the right side of the filter cylinder 1. Semi-circular support plates B31 are welded to the front and back positions at the top of the sundry cylinder 3, which have the same structure and size as the semi-circular support plates A11. A collecting groove 32 with an inverted hopper structure is integrally formed at the bottom of the sundry cylinder 3 for concentrating impurity particles. A discharge hole 33 is connected to the bottom of the collecting groove 32 for convenient centralized discharge. A filtering and turning mechanism 2 is arranged between the filter cylinder 1 and the sundry cylinder 3. The filtering and turning mechanism 2 includes a sleeve A21. The sleeve A21 is welded or bolted between the filter cylinder 1 and the sundry cylinder 3 in the front-back direction. A servo motor A22 is installed at the rear end of the sleeve A21 through bolts. The output end of the servo motor A22 is connected to a rotating shaft A23 located inside the sleeve A21. Rotating plates 24 of the same size are provided at the front and rear ends of the sleeve A21. One end of the rotating plate 24 is fixed to the rotating shaft A23, and a fixed shaft 25 is welded to the opposite side of the other end. A semi-circular filter shell 26 is welded between the two fixed shafts 25. Filter holes 27 are evenly distributed on the semi-circular filter shell 26.

[0031] Further, the rotating plate 24 is braked by the servo motor A22 and rotates forward and backward by an angle of 180°. The semi-circular filter shell 26 is driven by the rotating plate 24, which is convenient for the particulate impurities in the semi-circular filter shell 26 to be inverted from the filter cylinder 1 into the sundry cylinder 3.

[0032] Further, the fixed shaft 25 rotates and is located inside the semi-circular support plate A11 or the semi-circular support plate B31. The fixed shaft 25 is supported by the semi-circular support plate A11 or the semi-circular support plate B31. Synchronously, the semi-circular filter shell 26 is located inside the top opening of the filter cylinder 1 or the sundry cylinder 3. After the semi-circular filter shell 26 rotates and pours in the particulate impurities, it is located inside the top opening of the sundry cylinder 3, avoiding the particulate impurities from being poured outside the sundry cylinder 3.

[0033] Furthermore, the diameter of the semi-circular filter housing 26 has a clearance of 2-5 mm with the inner diameter of the filter cartridge 1 or the debris cartridge 3, avoiding too large a clearance between the semi-circular filter housing 26 and the filter cartridge 1 or the debris cartridge 3, so that particulate impurities do not leak through the clearance, and also avoiding bumps on the surfaces of the semi-circular filter housing 26 and the filter cartridge 1 or the debris cartridge 3.

[0034] During the specific implementation process, the water to be filtered enters from the top of the filter cartridge 1, and during this period, it passes through the filter holes 27 of the semi-circular filter housing 26 and enters the interior of the filter cartridge 1. The filter holes 27 can filter particulate debris in the water inside the semi-circular filter housing 26, and the water after filtering the particulate debris is then discharged from the water outlet 12; after a certain period of time, when it is notified that water enters the filter cartridge 1, the servo motor A22 is started to rotate the rotating shaft A by 180°, and the semi-circular filter housing 26 is driven to rotate and buckle into the debris cartridge 3 through the rotating plate 24 and the fixed shaft 25, so that the particulate impurities in the semi-circular filter housing 26 fall into the debris cartridge 3, are centrally collected through the collection groove 32, and then discharged from the bottom discharge hole 33. The servo motor A22 flips to return the semi-circular filter housing 26 to the top opening of the filter cartridge 1, forming a cycle. There is no need for manual cleaning, and the automatic cleaning operation of the particulate debris in the circulating water is realized.

[0035] Embodiment 2

[0036] In order to prevent the particulate impurities in the debris cartridge 3 from remaining in the debris cartridge 3, an improvement is made on the basis of Embodiment 1, as Figures 4-5 shown. In this embodiment, the debris cartridge 3 includes a cleaning device 34. The cleaning device 34 includes an annular pipe 341, a pipe joint 342, and drain holes 343. The annular pipe 341 is welded to the inner wall of the debris cartridge 3. The annular pipe 341 is externally connected with a pipe joint 342, and drain holes 343 with downward openings are evenly distributed at the bottom of the annular pipe 341.

[0037] During the specific implementation process, the pipe joint 342 is connected to an external water pump. Water flows into the annular pipe 341 and then drains down through the drain holes 343. The circular structure of the annular pipe 341 can clean the inner wall of the debris cartridge 3 without dead angles, so that the impurities adhering to the inner wall of the debris cartridge 3 and unable to fall can flow out through the discharge hole 33 along with the water flow.

[0038] Embodiment 3

[0039] In order to scrape off the impurities adhering to the inner surface of the semi-circular filter housing 26 and clean the foreign objects blocking the filter holes to avoid blockage of the filter holes, an improvement is made on the basis of Embodiment 2, as Figures 6-8As shown, in this embodiment, the sundry cylinder 3 further includes a slag scraping device 35. The slag scraping device 35 includes a sleeve B351, a servo motor B352, a rotating shaft B353, an arc-shaped frame 354, and an arc-shaped scraper 355. The sleeve B351 is located at the center bottom of the sundry cylinder 3 and is welded vertically. A support column 356 is perpendicularly welded between the bottom of the sleeve B351 and the filter cylinder 1 to increase the stability of the sleeve B351. A servo motor B352 is fixed at the bottom of the sleeve B351. The output end of the servo motor B352 is connected to a rotating shaft B353 located inside the sleeve B351 to assist the rotating shaft B353 to rotate along the axis of the sundry cylinder 3. An arc-shaped frame 354 is welded to the top of the rotating shaft B353. An arc-shaped scraper 355 is arranged on the arc-shaped frame 354. The arc-shaped scraper 355 is made of silica gel and has the same radian as the semi-circular filter shell 26. The inner wall of the semi-circular filter shell 26 and the filter holes 27 are cleaned by the arc-shaped scraper 355.

[0040] Further, a U-shaped groove 3541 is formed on the outer arc of the arc-shaped frame 354. The arc-shaped scraper 355 made of silica gel is inserted and fixed with the U-shaped groove 3541 by using its own elastic deformation, which also facilitates the disassembly and replacement of the arc-shaped scraper 355.

[0041] During the specific implementation process, when the semi-circular filter shell 26 rotates above the sundry cylinder 3, the servo motor B352 is started to make the arc-shaped scraper 355 rotate. The arc-shaped scraper 355 scrapes the impurities on the inner wall of the semi-circular filter shell 26 and cleans the foreign matters in the filter holes 27, ensuring the cleanliness of the inner surface of the semi-circular filter shell 26 and also avoiding the blockage phenomenon caused by the long-term use of the filter holes 27.

[0042] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
