Description

Technical Field

[0001] The utility model relates to the technical field of wastewater recycling devices, in particular to a green building construction wastewater recycling device. Background Art

[0002] Construction wastewater refers to wastewater containing silt, suspended matter, and other pollutants generated during the construction process. In order to save water resources, construction wastewater needs to be treated and recycled.

[0003] When the existing construction wastewater is recycled, it needs to be transported to the filtering equipment for filtration to filter out the silt, suspended matter and impurities in the wastewater. However, when the existing filtering equipment is used, the sewage is transported to the filter element or filter screen for filtration. Since the filter element or filter screen cannot be cleaned while filtering, the impurities in the sewage will clog the filter element or filter screen, affecting the filtration. When the filter screen or filter element is damaged and needs to be replaced, the staff needs to open the filtering equipment and then remove the filter element or filter screen in the filtering equipment for replacement. Since the internal space of the filtering equipment is small, it is troublesome to remove the filter element or filter screen and inconvenient to replace it. To this end, we propose a green building construction wastewater recycling device. Utility Model Content

DETAILED DESCRIPTION

[0027] 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.

[0028] Reference Figure 1-Figure 5 A green building construction wastewater recycling device includes a box body 2, a control cabinet 23 is installed on one side of the box body 2, and a controller is arranged inside the control cabinet 23. The controller is a control mainboard or a host.

[0030] like Figure 1As shown, a water inlet pipe 7 is installed at one end of the top of the box 2, two filter plates 5 are stacked inside the box 2, there is a gap between the two filter plates 5, and the two filter plates 5 are inclined, and a circulation pipe 13 is installed at one end of the bottom of the box 2. In actual use, the water inlet pipe 7 transports sewage to the inside of the box 2. When the sewage passes through the two filter plates 5, impurities in the sewage are filtered out by the two filter plates 5, and pure water passes through the filter plates 5 and flows to the bottom of the box 2, and is finally discharged through the circulation pipe 13, which is convenient for recycling.

[0031] It should be noted that the pore size of the filter plate 5 located above is larger than that of the filter plate 5 located below. The filter plate 5 located above can filter out large particles of impurities in the sewage, and small particles of impurities will pass through the filter plate 5 above and flow along with the sewage to the filter plate 5 below. The small particles of impurities can be filtered out by the filter plate 5 below, and the filtration is sufficient.

[0032] It should be noted that if Figure 1 As shown, a first guide plate 10 is provided between the two filter plates 5. The first guide plate 10 is inclined and fixed on the side wall of the box body 2. There is a gap between one end of the first guide plate 10 and the side wall of the box body 2. After the sewage passes through the upper filter plate 5, part of the sewage will fall on the first guide plate 10 and flow along the first guide plate 10 to the top of the next filter plate 5. This can increase the filtration area of ​​the lower filter plate 5 and improve the use effect.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, two pairs of strip mounting plates 4 are installed inside the box body 2, each pair of strip mounting plates 4 is located above the corresponding filter plate 5, and a pair of connecting shafts 18 are installed between each pair of strip mounting plates 4, and conveying chains 6 are provided at both ends of each pair of connecting shafts 18, and the conveying chain 6 is meshed with sprockets installed at both ends of each pair of connecting shafts 18. The end of one connecting shaft 18 in each pair of connecting shafts 18 is connected to a first driving motor 9, and the first driving motor 9 is fixed on the side wall of the box body 2. The first driving motor 9 is connected to the controller through a wire. In actual use, the connecting shaft 18 can be driven to rotate by the first driving motor 9, and then the conveying chain 6 can be driven to move.

[0034] like Figure 4 As shown, a plurality of scrapers 8 are installed between two adjacent conveyor chains 6, and the bottom ends of the scrapers 8 are gap-matched with the tops of the corresponding filter plates 5. Two slag discharge grooves 17 are provided on one side of the housing 2, and the slag discharge grooves 17 are both located above the corresponding filter plates 5, and one end of the scraper 8 extends out of the slag discharge groove 17. In actual use, the conveyor chain 6 drives the scraper 8 to move along the tops of the filter plates 5, and the impurities filtered out of the tops of the filter plates 5 are discharged from the housing 2 through the slag discharge grooves 17, so as to prevent the filter plates 5 from being clogged by stains.

[0035] like Figure 5 As shown, two pairs of strip connecting plates 21 are provided on both sides of the inside of the box body 2, one side of each strip connecting plate 21 is slidably connected to the guide rail on the side wall of the box body 2 through a slider, and both ends of the filter plate 5 are fixed to the corresponding strip connecting plates 21, and the filter plate 5 is fixed to the strip connecting plates 21 by bolts or locks, so that it is firmly fixed and convenient for disassembly and replacement.

[0036] like Figure 5 As shown, a connecting block 20 is vertically installed at one end of the bottom of each strip connecting plate 21, and two pairs of screw rods 3 are rotatably connected on both sides of the interior of the box body 2. Each screw rod 3 passes through the corresponding connecting block 20 and is threadedly matched with the corresponding connecting block 20. One end of each screw rod 3 is connected to a second drive motor 14, which is fixed on the side wall of the box body 2. The second drive motor 14 is connected to the controller through a wire. Two through grooves 22 are provided on one side of the box body 2 close to the second drive motor 14. The strip connecting plate 21 and the filter plate 5 are aligned with the corresponding through grooves 22. When the filter plate 5 needs to be replaced, the second drive motor 14 can drive the screw rod 3 to rotate, so that the strip connecting plate 21 and the filter plate 5 pass through the through groove 22 and move out of the box body 2, which is convenient for replacement.

[0037] It should be noted that if Figure 2 As shown, a sealing cover 15 is provided inside the through groove 22, and the sealing cover 15 is sealed with the inner wall of the through groove 22, and the sealing cover 15 is fixed to the side wall of the box body 2 by a lock. Under the action of the sealing cover 15, the through groove 22 can be sealed, so that when the sewage is filtered, the sewage will not leak out from the through groove 22.

[0038] Specifically, when the utility model is in use, the staff transports the sewage into the box body 2 along the water inlet pipe 7, and the sewage will fall on the upper filter plate 5 under the action of gravity.
