DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] When implementing: Figure 1-4 As shown, an artificial wetland domestic sewage treatment device includes: a filter screen filter chamber 1 and a filler filter chamber 2, the filler filter chamber 2 is fixedly connected and communicated with one end of the filter screen filter chamber 1; and a filter device 3, which is installed inside the filter screen filter chamber 1.

[0023] The filter screen filtering chamber 1 comprises a first water tank, one end of which is fixedly connected and communicated with a water inlet pipe, a mesh plate is fixedly connected to the inner wall of the first water tank, a rectangular frame 31 is placed on the top of the mesh plate, and the rectangular frame 31 is arranged below the water inlet pipe. A cover plate is placed on the top of the first water tank, a float is slidably connected to the top of the cover plate, and the bottom of the float passes through the cover plate and extends to the inside of the rectangular frame 31; the filler filtering chamber 2 comprises a second water tank fixedly connected and communicated with one end of the first water tank, the connection point between the first water tank and the second water tank is arranged below the mesh plate, and the inside of the second water tank is sequentially provided with a fly ash filler layer, a coarse brick recycled aggregate filler layer, a fine brick recycled aggregate filler layer and a zeolite filler layer from bottom to top, a partition is fixedly connected to the inner bottom wall of the second water tank, and the height of the partition is higher than the height of the zeolite filler layer, and the end of the second water tank away from the first water tank is fixedly connected and communicated with a water outlet pipe, and the zeolite filler layer and the water outlet pipe are respectively arranged on both sides of the partition;

[0024] When the sewage enters the first water tank through the water inlet pipe, the sewage first enters the rectangular frame 31, and the filter screen 32 filters out the solid impurities in the sewage. Then the filtered sewage enters the second water tank along the first water tank, and the sewage is filtered through the fly ash filler layer, the coarse brick recycled aggregate filler layer, the fine brick recycled aggregate filler layer and the zeolite filler layer in turn. Finally, the purified water overflows the partition and flows into the outlet pipe, and is finally discharged along the outlet pipe.

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, the filtering device 3 includes a rectangular frame 31 placed inside the filter screen filtering chamber 1, the inner wall of the rectangular frame 31 is embedded with a filter screen 32, the top of the rectangular frame 31 is fixedly connected with an adjusting handle 33, the surface of the rectangular frame 31 is sleeved with a rubber sealing ring 34 in contact with the filter screen filtering chamber 1, and the surface of the adjusting handle 33 is installed with a pressure regulating mechanism 35 fixedly connected to the rubber sealing ring 34; the corners of the opening on the rectangular frame 31 are all beveled, and the specifications of the bevel match the thickness of the rectangular frame 31; the surface of the rectangular frame 31 is opened with a rectangular reserved groove 311, and the rubber sealing ring 34 is sleeved inside the rectangular reserved groove 311.

[0026] like Figure 3 and Figure 4As shown, a mounting cavity 331 is provided on the surface of the adjusting handle 33, a cavity is provided inside the rubber sealing ring 34, and the pressure regulating mechanism 35 includes a bolt 351, which is threadedly connected to the inner side of the mounting cavity 331, and a pressure plate 352 which is rotatably connected to the mounting cavity 331 is rotatably connected to the bottom of the bolt 351, and an air bag 353 which is fixedly connected to the inside of the mounting cavity 331 is fixedly connected to the bottom of the pressure plate 352, and the air bag 353 is in a compressed state at this time, and an air guide tube 354 is fixedly connected to the surface of the air bag 353 and is connected to the air guide tube 354, one end of the air guide tube 354 passes through the mounting cavity 331, the adjusting handle 33, the rectangular frame 31 and the rubber sealing ring 34 in sequence and is fixedly connected to and connected to the cavity; the horizontal cross-sectional shapes of the connection between the pressure plate 352 and the mounting cavity 331 and the pressure plate 352 are all matching rectangles; the top of the bolt 351 is fixedly connected to a turning handle 355, and the corners of the turning handle 355 are rounded; the horizontal cross-sectional shape of the turning handle 355 is a straight line.

[0027] When the utility model is in use, when the staff needs to install the filter screen 32, the staff only needs to place the rectangular frame 31 and the filter screen 32 above the mesh plate by adjusting the handle 33, and then the staff rotates the bolt 351 in the corresponding direction, and the bolt 351 drives the pressure plate 352 to move down along the installation cavity 331, and the pressure plate 352 squeezes the air bag 353, and the air bag 353 squeezes the internal gas into the cavity of the rubber sealing ring 34 through the air guide tube 354, and the rubber sealing ring 34 expands outwards until the gap between the rectangular frame 31 and the first water tank is blocked. In the subsequent use process, water cannot enter the gap between the rectangular frame 31 and the first water tank, which effectively reduces the probability of impurities entering the gap between the rectangular frame 31 and the first water tank, which can not only improve the effective filtration rate of sewage, but also reduce the difficulty of removing the rectangular frame 31 blocked by impurities, making it more convenient for the staff to maintain;

[0028] When the staff needs to clean the impurities on the filter 32, the staff only needs to turn the bolt 351, the bolt 351 drives the pressure plate 352 to move upward, and the pressure plate 352 stretches the airbag 353, so that the airbag 353 expands and absorbs the gas in the cavity of the rubber sealing ring 34 into it through the air duct 354. At this time, the rubber sealing ring 34 shrinks and shrivels, and separates from the first water tank, which can reduce the resistance of the staff to take out the rectangular frame 31, so that the staff can easily take out the rectangular frame 31.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
