DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-Figure 4A green building construction wastewater recycling and treatment device comprises a base 1, a treatment box 2 with an opening on the top is installed on the top of the base 1, two pairs of strip frames 9 are stacked inside the treatment box 2, the sides of each pair of strip frames 9 are fixed on the inner wall of the treatment box 2, and a filter screen 8 is installed between each pair of strip frames 9, the aperture of the upper filter screen 8 is larger than the aperture of the lower filter screen 8, and a drain pipe 30 is installed at one end of the bottom of the treatment box 2. In actual use, the staff transports the sewage from the opening on the top of the treatment box 2 into the treatment box 2, and the sewage will fall on the filter screen 8 and filter the sewage through the filter screen 8. In this way, the sewage can be double-filtered by the two filter screens 8, and the filtration is sufficient. The filtered water is transported to the storage tank through the drain pipe 30 for recycling, which is convenient for subsequent use.

[0027] like Figure 1 and Figure 3 As shown, each filter screen 8 is provided with a rotating shaft 6 at both ends of the top, one end of the rotating shaft 6 is rotatably connected to the side wall of the processing box 2, and a strip connecting plate 7 is installed between each pair of rotating shafts 6, and a plurality of first connecting rods 10 are installed on the side of each strip connecting plate 7, and the bottom of the first connecting rod 10 is connected through a scraper 5, and the bottom of the scraper 5 is matched with the corresponding top of the filter screen 8. Two pairs of slag discharge ports 4 are installed on both sides of the processing box 2, and the bottom of each pair of slag discharge ports 4 is flush with the top of the strip frame 9. In actual use, the impurities filtered on the filter screen 8 can be scraped off by the scraper 5 and discharged from the slag discharge port 4.

[0028] It should be noted that if Figure 4 As shown, the filter screen 8 is an arc-shaped structure, and when the scraper 5 rotates to the uppermost position, the scraper 5 is tilted downward. By setting the filter screen 8 to an arc shape, the filtering area of ​​the filter screen 8 can be increased, and the filtering effect can be improved. When the scraper 5 rotates to the top of the filter screen 8, the scraper 5 will still be tilted downward, so that the impurities scraped off by the scraper 5 will not flow back to the filter screen 8 along the scraper 5.

[0029] It should be noted that if Figure 4 As shown, the top of the strip frame 9 is tilted downward, so that when the scraper 5 scrapes impurities off the surface of the filter 8, the impurities will move out of the processing box 2 along the inclined surface of the top of the strip frame 9, thereby preventing impurities from remaining in the processing box 2.

[0030] like Figure 3 As shown, the end of the rotating shaft 6 located at the same end of the processing box 2 is connected to a gear 14, and a rack 12 is provided below the gear 14. The rack 12 is meshed with the corresponding gear 14. Under the action of the rack 12, the gear 14 can be controlled to rotate, thereby driving the scraper 5 to rotate along the top of the filter screen 8 while filtering the sewage.

[0031] It should be noted that if Figure 1As shown, a protective box 11 is installed at one end of the processing box 2 close to the gear 14, and the gear 14 and the rack 12 are both located in the protective box 11, and one end of the rack 12 extends out of the protective box 11. The connecting part between the gear 14 and the rack 12 can be shielded by the protective box 11, which can avoid damage to the gear 14 and will not cause injuries to the staff who accidentally touch the connecting part between the gear 14 and the rack 12.

[0032] like Figure 1 As shown, a wedge-shaped guide rail 15 is installed at the inner bottom end of the protective box 11, and the bottom of the rack 12 is slidably matched with the wedge-shaped guide rail 15 through a wedge-shaped slider 33. Under the action of the wedge-shaped guide rail 15 and the wedge-shaped slider 33, the rack 12 can be limited so that the rack 12 remains stable.

[0033] like Figure 3 As shown, one end of the two racks 12 is connected through a strip connecting block 13, one side of the strip connecting block 13 is connected to a second connecting rod 16 through a hinge seat, and the other end of the second connecting rod 16 is rotatably connected to the eccentric wheel 17, and a mounting seat 20 is installed at one end of the processing box 2, and the top of the mounting seat 20 is rotatably connected to the eccentric wheel 17 through a fixed plate 19, and a first pulley 18 is installed at one end of the eccentric wheel 17, and a second pulley 21 is installed at the bottom of the side of the fixed plate 19, and the second pulley 21 is connected to the first pulley 18. They are connected by a belt, and one end of the second pulley 21 is connected to a second drive motor 32, which is fixed to the top of the mounting base 20. In actual use, the second drive motor 32 can drive the eccentric wheel 17 to rotate under the action of the first pulley 18 and the second pulley 21, and then the rack 12 can be controlled to reciprocate horizontally through the second connecting rod 16, so that the gear 14 and the scraper 5 can reciprocate, and the scraper 5 can continuously scrape away impurities filtered by the filter screen 8 to prevent the filter screen 8 from being blocked.

[0034] like Figure 1 and Figure 2 As shown, strip mounting plates 27 are installed on both sides of the base 1, and a conveying trough body 22 with an opening facing upward is installed on the top of each strip mounting plate 27. The conveying trough body 22 is located below the slag discharge port 4, and the interior of the conveying trough body 22 is rotatably connected with a spiral conveying shaft 25, one end of the spiral conveying shaft 25 is connected to a first driving motor 28, and the first driving motor 28 is fixed to the end of the conveying trough body 22, and a slag discharge pipe 23 is installed at one end of the bottom of the conveying trough body 22. In actual use, the impurities scraped off by the scraper 5 will pass through the slag discharge port 4 and fall into the conveying trough body 22 below. At this time, the spiral conveying shaft 25 can be driven to rotate by the first driving motor 28 to discharge the impurities falling into the conveying trough body 22 from the slag discharge pipe 23.

[0035] like Figure 1 and Figure 2As shown, a plurality of legs 26 are installed on the bottom edge of the base 1, and a storage plate 29 is connected between the two legs 26 located at the same end. A collecting box 24 is provided on the top of the storage plate 29, and the top of the collecting box 24 is located below the slag discharge pipe 23. Impurities discharged from the slag discharge pipe 23 will fall into the collecting box 24, so that the impurities filtered by the filter screen 8 can be collected together for easy recycling.

[0036] Specifically, when the utility model is in use, the staff transports the sewage from the top opening of the treatment box 2 to the treatment box 2, and the sewage first falls on the filter screen 8 located above, and the large particles of impurities in the sewage are filtered out by the filter screen 8. The water after preliminary filtration and some small particles of impurities will pass through the upper filter screen 8 and fall into the surface of the lower filter screen 8, and the remaining impurities in the sewage will be filtered out by the lower filter screen 8. The filtered water passes through the lower filter screen 8 and is discharged from the drain pipe 30 to the storage tank for recovery. While filtering, the second drive motor 32 is controlled to work, and the second drive motor 32 drives the eccentric wheel 17 to rotate through the first pulley 18 and the second pulley 21. When the eccentric wheel 17 rotates, it will drive the two racks 12 to reciprocate horizontally under the action of the second connecting rod 16, so that the gear 14 follows the rack 12 to reciprocate, and finally the scraper 5 follows the gear 14 to reciprocate along the top of the filter screen 8, continuously scraping off the impurities filtered on the surface of the filter screen 8 and discharging them from the slag discharge port 4. The impurities discharged from the slag discharge port 4 will fall into the conveying trough 22 along the guide plate 3 under the action of gravity. At the same time, the first drive motor 28 is controlled to work, and the first drive motor 28 drives the spiral conveying shaft 25 to rotate, and the impurities falling into the conveying trough 22 are discharged from the slag discharge pipe 23 to the collection box 24 for centralized collection, which is convenient for recycling.

[0037] Furthermore, Figure 1 and Figure 2 As shown, a guide plate 3 is provided at the bottom of each slag discharge port 4, one side of the guide plate 3 is fixed on the side wall of the processing box 2, the guide plates 3 are all inclined, and the ends of the guide plates 3 are all located above the conveying trough body 22. The impurities discharged from the slag discharge port 4 can be guided by the guide plate 3 so that the impurities can fall into the conveying trough body 22 below.

[0038] like Figure 1 As shown, strip baffles 31 are installed on both sides of the top of each guide plate 3, and the strip baffles 31 can prevent impurities from scattering from both sides of the guide plate 3.

[0039] Furthermore, Figure 4As shown, a plurality of pairs of second reinforcing ribs 35 are equidistantly installed at the bottom of each pair of strip frames 9, the second reinforcing ribs 35 are fixed to the bottom of the filter screen 8, and a plurality of first reinforcing ribs 34 are installed between two adjacent second reinforcing ribs 35, the tops of the first reinforcing ribs 34 are fixed to the top of the filter screen 8, and the filter screen 8 can be supported by the first reinforcing ribs 34 and the second reinforcing ribs 35, so that the filter screen 8 will not be deformed when the scraper 5 scrapes off impurities.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
