Detailed implementation manners

[0013] Combined with the drawings and embodiments below, the specific implementation manners of the present invention will be further described in detail. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0014] As Figures 1 to 3 shown, a grading filtration device for sewage treatment according to the present invention includes a device main body 1; it also includes a mounting plate 2, a first clamping block 3, a support plate 4, a multi-stage filtering mechanism 5, a fixing assembly and a cleaning mechanism.

The outer side of the mounting plate 2 and the inner side of this group of reserved holes are slidably sleeved. The left end of the mounting plate 2 is provided with a fixing assembly, and the right end of the mounting plate 2 is connected to the left end of the support plate 4. The outer side of the support plate 4 passes through the reserved hole and is slidably attached to the inner wall of the working cavity of the device main body 1. A clamping groove is provided at the right end of the working cavity of the device main body 1. The first clamping block 3 is clamped with this group of clamping grooves, and the right end of the support plate 4 is connected to the left end of the first clamping block 3. A reserved hole is provided at the top of the support plate 4, and a multi-stage filtering mechanism 5 is provided in the reserved hole of the support plate 4. A sewage collection tank is provided at the right side of the top of the support plate 4, and a cleaning mechanism is provided at the top left of the working cavity of the device main body 1; when disassembling, the staff first releases the fixation of the fixing assembly, and then pulls the mounting plate, so that the mounting plate drives the support plate to slide. During this process, the cleaning mechanism starts to clean the impurity particles and the like on the surface of the multi-stage filtering mechanism, so that they fall into the sewage collection tank of the support plate until the staff pulls the support plate to drive the multi-stage filtering mechanism out of the working cavity of the device main body, and then cleaning can be started. When the staff disassembles the multi-stage filtering mechanism, the filtered impurity particles and the like can be centrally cleaned, so as to facilitate the subsequent treatment by the staff, thereby improving the convenience of the device, and thus enhancing the practicability.

[0015] Preferably, as in the above embodiment, the cleaning mechanism includes a scraper 6, a cleaning brush 7, a connecting plate 8, a connecting block 9, a fixing block 10 and a rebounding component.

The top of the connecting block 9 is slidably sleeved with the bottom of the fixing block 10 through the rebounding component, and the bottom of the connecting block 9 is connected to the top of the connecting plate 8. The left end of the bottom of the connecting plate 8 is provided with a scraper 6, and the right side of the bottom of the connecting plate 8 is provided with a cleaning brush 7. The bottoms of the scraper 6 and the cleaning brush 7 are respectively in sliding contact with the top of the multi-stage filtering mechanism 5. When the staff pulls the mounting plate to disassemble the support plate, the mounting plate drives the support plate to move to the right, and the multi-stage filtering mechanism on the top of the support plate moves accordingly. At this time, the scraper and the cleaning brush will slide relative to the surface of the filtering mechanism, scraping off the impurity particles accumulated on the surface of the filtering layer. The impurities slide along the edge of the filtering layer into the sewage collection tank on the right side of the support plate, completing the cleaning of the surface of the filtering layer synchronously during the disassembly process without additional operations, achieving efficient maintenance of cleaning during disassembly, and thus enhancing the practicability.

[0016] Preferably, as in the above embodiment, the fixing component includes a baffle 11, four groups of connecting screws 12, four groups of mounting blocks 13 and four groups of positioning blocks 14. The left end of the mounting plate 2 is connected to the right end of the baffle 11. Two groups of mounting blocks 13 are evenly arranged on the top and bottom of the baffle 11 respectively. Four groups of positioning blocks 14 are evenly arranged on the left end of the device main body 1, and a threaded hole is provided through one group of mounting blocks 13 and the corresponding positioning block 14 for each of the four groups of connecting screws 12. The right ends of the four groups of connecting screws 12 are respectively threadedly connected to the corresponding mounting blocks 13 and positioning blocks 14 through the threaded holes, enabling the staff to quickly fix and install the multi-stage filtering mechanism, and thus enhancing the practicability.

[0017] Preferably, as in the above embodiment, the telescopic component includes multiple groups of damping rods 15 and multiple groups of connecting springs 16. A groove is provided at the bottom of the fixing block 10. The top of the groove of the fixing block 10 is evenly connected to the top of multiple groups of damping rods 15, and the top of the connecting block 9 is evenly connected to the bottom of multiple groups of damping rods 15. The outer sides of multiple groups of damping rods 15 are respectively sleeved with the inner sides of a group of connecting springs 16, and the top of the connecting block 9 is slidably sleeved with the groove of the fixing block 10. The connecting block slides in the groove of the fixing block, and the damping rods and the connecting springs provide elastic buffering, so that the scraper and the brush are always in close contact with the surface of the filtering layer, ensuring that impurities are effectively scraped off, and enabling the cleaning mechanism to adapt to the slight deformation of the filtering layer, ensuring uniform cleaning force and avoiding damage to the filtering material, and thus enhancing the practicability.

[0018] Preferably, as in the above embodiment, it further includes four groups of rotary handles 17, and a group of rotary handles 17 are respectively arranged at the left ends of the four groups of connecting screws 12, enabling the staff to quickly rotate the connecting screws, and thus enhancing the practicability.

[0019] Preferably, as an embodiment of the above, it further includes an annular sealing rubber ring 18. The right end of the baffle 11 is connected to the left end of the annular sealing rubber ring 18, and the inner side of the annular sealing rubber ring 18 is sleeved on the left end of the outer side of the mounting plate 2. The right end of the annular sealing rubber ring 18 is closely attached to the left end of the device body 1, enhancing the sealing reliability, avoiding sewage leakage from affecting the treatment effect or causing secondary pollution, and thus enhancing the practicability.

[0020] Preferably, as an embodiment of the above, it further includes a handle 19. The left end of the baffle 11 is connected to the right end of a set of handles 19, making the pulling operation of the mounting plate more labor-saving, improving the disassembly efficiency, and thus enhancing the practicability.

[0021] For a hierarchical filtration device for sewage treatment according to the present invention, its working principle is that the staff rotates the rotating handle, so that the four connecting screws are respectively disengaged from the threaded connection with the positioning blocks. The staff pulls the handle, and pulls the mounting plate together with the support plate and the multi-stage filtration mechanism out of the device body to the right. During the extraction process, the cleaning mechanism fixed on the top of the device body remains stationary, and the scraper and the brush slide relative to the surface of the filtration layer to scrape off the impurity particles. The impurities fall along the edge of the filtration layer into the sewage collection tank on the right side of the support plate. After the support plate is completely pulled out, the impurities in the sewage collection tank can be directly poured out. The multi-stage filtration mechanism can be taken out from the reserved holes in the support plate for cleaning or replacement.
