[0033] Reference Figure 1-3 The figure shows a preferred embodiment of the present invention.

[0034] The used wastewater collection and treatment structure based on water recycling includes a collection tank 100 for collecting used wastewater and a sedimentation tank 400 for precipitating the used wastewater to form reclaimed water. The collection tank 100 is connected to a plurality of collection pipes 104, and the used wastewater enters the collection tank 100 through the collection pipes 104; the used wastewater is collected into the collection tank 100 through the collection pipes 104, and the used wastewater in the collection tank 100 then enters the sedimentation tank 400, and is precipitated in the sedimentation tank 400 to form reclaimed water.

[0035] A connecting pipe 109 is connected between the collection tank 100 and the sedimentation tank 400, and the used wastewater in the collection tank 100 enters the sedimentation tank 400 through the connecting pipe 109; the upper part of the sedimentation tank 400 has an outlet 404 for discharging reclaimed water, and the outlet 404 is connected to multiple water supply pipes that transmit reclaimed water to water-using equipment.

[0036] A flexible, flat collection membrane layer 106 is provided in the middle of the collection tank 100. The collection tank 100 has a submembrane cavity 101 located below the collection membrane layer 106 and an upper membrane cavity 102 located above the collection membrane layer 106. A collection pipe 104 is connected to the submembrane cavity 101, and the collection membrane layer 106 is provided with a plurality of collection holes extending vertically therethrough. Wastewater enters the submembrane cavity 101 through the collection pipe 104. The wastewater in the submembrane cavity 101 squeezes the collection membrane layer 106 from bottom to top, passes through the collection holes, and is placed in the upper membrane cavity 102. The collection membrane layer 106 collects and filters the wastewater.

[0037] The wastewater in the upper chamber 102 of the membrane enters the sedimentation tank 400 through the connecting pipe 109. After the wastewater flows and settles in the sedimentation tank 400, it forms reclaimed water, which is then discharged to the water supply pipe through the outlet 404.

[0038] The wastewater collection and treatment structure based on water recycling provided above can collect wastewater through the collection pipe 104, so that the wastewater enters the sub-membrane chamber 101, and the wastewater rises from bottom to top in the sub-membrane chamber 101, squeezes through the collection membrane layer 106, enters the upper membrane chamber 102, and then enters the sedimentation tank 400 through the connecting pipe 109. After the wastewater is precipitated in the sedimentation tank 400, it forms reclaimed water, which is then discharged to the water supply pipe through the water outlet 404 for use by water-using equipment, thereby achieving effective treatment of wastewater.

[0039] When the used wastewater passes through the collection membrane layer 106, the collection membrane layer 106 elastically deforms, forming a preliminary blocking filtration for the used wastewater, and the used wastewater rises from the bottom to the top, which can achieve preliminary sedimentation filtration, so as to improve the sedimentation treatment efficiency of the subsequent sedimentation tank 400 for the used wastewater, which not only improves the collection and treatment efficiency of the used wastewater, but also makes the water quality of the formed reclaimed water meet the requirements of water equipment.

[0040] In this embodiment, the bottom of the collection membrane layer 106 has a bottom surface facing the sub-membrane cavity 101, and the bottom surface is covered with a bottom velvet layer 107. In this way, the used wastewater is blocked and disturbed by the bottom velvet layer 107 during the process of passing through the collection membrane layer 106, so that impurities in the used wastewater can be retained in the sub-membrane cavity 101, greatly improving the preliminary sedimentation and filtration treatment effect of the used wastewater.

[0041] In this embodiment, a dense mesh layer 103 is provided in the sub-membrane cavity 101, and the dense mesh layer 103 is located below the collection membrane layer 106 and is arranged horizontally; the collection pipe 104 has an internal section 1041 extending into the sub-membrane cavity 101, and the internal section 1041 is located below the dense mesh layer 103; the end of the internal section 1041 is arranged in a closed manner, and the periphery of the internal section 1041 is provided with a plurality of peripheral holes, and the used wastewater in the internal section 1041 is discharged into the sub-membrane cavity 101 through the plurality of peripheral holes.

[0042] By arranging multiple peripheral holes, the internal section 1041 can discharge the used wastewater at multiple positions, so that the used wastewater can be discharged at multiple positions and directions in the sub-membrane cavity 101; in addition, by arranging the dense mesh layer 103, the used wastewater can be coarsely filtered before passing through the collection membrane layer 106.

[0043] In this embodiment, the inner section 1041 is fixedly connected to the dense mesh layer 103 and arranged in a spiral pattern on the dense mesh layer 103. The peripheral holes are arranged downward away from the dense mesh layer 103 and are spaced apart from the bottom of the sub-membrane cavity 101. The inner section 1041 is arranged in a spiral pattern and fixed to the dense mesh layer 103. This facilitates the arrangement of the inner section 1041 and the divergent distribution of the multiple peripheral holes of the inner section 1041 in the sub-membrane cavity 101, thereby facilitating the injection of wastewater into the sub-membrane cavity 101 from multiple locations and angles.

[0044] During the process of injecting the used wastewater into the sub-membrane cavity 101 , the used wastewater is injected downward, and as the used wastewater increases in the sub-membrane cavity 101 , the used wastewater surges upward from the bottom, which is beneficial to the sedimentation treatment of the used wastewater.

[0045] In this embodiment, an elastic elastic column 108 is provided in the middle of the collection film layer 106, the top of the elastic column 108 is docked in the middle of the collection film layer 106, and the bottom of the elastic column 108 is docked in the middle of the dense mesh layer 103; the elastic column 108 is in a stretched state, and the middle of the collection film layer 106 is arranged to be concave downward.

[0046] By arranging elastic columns 108 between the collection membrane layer 106 and the dense mesh layer 103, the elastic deformation range of the isolation mesh layer can be limited, and the elastic columns 108 are arranged to concave the middle part of the isolation mesh layer downward, which is more conducive to the use of wastewater passing through the collection membrane layer 106, and the collection membrane layer 106 has a certain tension, which greatly improves the use of wastewater passing through the collection membrane layer 106.

[0047] In this embodiment, a rotating ring 300 is provided in the connecting pipe 109, and the outer periphery of the rotating ring 300 is rotatably connected to the inner wall of the connecting pipe; the rotating ring 300 encloses an enclosed area, and the enclosed area is provided with a filter layer 301; during the flow of wastewater in the connecting pipe 109, the wastewater is filtered through the filter layer 301, and the wastewater synchronously drives the filter layer 301 to rotate, so as to accelerate the speed of the wastewater passing through the filter layer 301.

[0048] When the wastewater flows in the connecting pipe 109, the rotating ring 300 is driven to rotate, and the filter layer 301 rotates synchronously, which greatly improves the efficiency of the wastewater passing through the filter layer 301, realizes the rotation filtration of the wastewater, and improves the filtering effect.

[0049] In this embodiment, the outer periphery of the filter layer 301 is butted against the inner sidewall of the rotating ring 300 , and the middle portion of the filter layer 301 protrudes toward the flow direction of the wastewater, forming a conical area 302 surrounded by the filter layer 301 ;

[0050] One end of the conical area 302 forms an open end 304 that is openly arranged, and the other end of the conical area 302 forms a protruding end 303; the used wastewater enters the conical area 302 through the open end 304 and flows toward the protruding end 303. In the process of the used wastewater passing through the filter layer 301, the filter layer 301 is synchronously driven to rotate.

[0051] The filter layer 301 surrounds and forms a conical area 302, which facilitates the use of wastewater to enter the conical area 302, thereby increasing the contact area between the use of wastewater and the filter layer 301, which is conducive to the use of wastewater passing through the filter layer 301; secondly, the filter layer 301 surrounds and forms a conical area 302, which facilitates the guidance of the flow direction of the use of wastewater; in addition, when the use of wastewater passes through the conical area 302, it is easier to drive the filter layer 301 to rotate.

[0052] In this embodiment, the protruding end 303 is arranged eccentrically and tilted, offset from the center of the filter layer 301. Along the direction from the open end 304 to the protruding end 303, the tapered region 302 is arranged in a curved shape, curving eccentrically away from the center of the filter layer 301. Because the tapered region 302 is curved and offset from the center of the filter layer 301, the force exerted on the filter layer 301 by the wastewater as it passes through the filter layer 301 generates a driving torque, facilitating the rotation of the filter layer 301.

[0053] In this embodiment, the sedimentation tank 400 is in the shape of an elongated strip, and has a sedimentation chamber extending in the shape of an elongated strip in the sedimentation tank 400. The lower portion of the sedimentation chamber forms a lower area 402. A lower layer 410 is provided above the lower area 402. An upper layer 409 is provided above the lower layer 410. A middle space 406 is defined between the upper layer 409 and the lower layer 410. The upper portion of the sedimentation chamber forms an upper area 405.

[0054] A longitudinally arranged water inlet 401 is provided at the front end of the sedimentation tank 400. The top of the water inlet 401 is connected to the connecting pipe 109, and the bottom of the water inlet 401 is connected to the lower area 402. A water outlet 404 is provided at the rear end of the sedimentation tank 400. The water outlet 404 is connected to the upper area 405. The water inlet 401 and the water outlet 404 are arranged in opposite directions.

[0055] The lower layer 410 is provided with a plurality of lower inclined paths 4101 that vertically penetrate the lower layer 410. The lower inclined paths 4101 are arranged obliquely from front to back along the direction from top to bottom of the lower layer 410. The upper layer 409 is provided with a plurality of upper inclined paths 4091 that vertically penetrate the upper layer 409. The upper inclined paths 4091 are arranged obliquely from back to front along the direction from top to bottom of the upper layer 409. The upper inclined paths 4091 are arranged obliquely in a different direction than the lower inclined paths 4101.

[0056] The lower area 402 is provided with a plurality of longitudinally arranged sedimentation membrane layers 403, and the sedimentation membrane layers 403 are provided with a plurality of transverse through holes. The plurality of sedimentation membrane layers 403 are sequentially spaced along the flow direction of the wastewater in the lower area 402;

[0057] The used wastewater enters the lower area 402 from top to bottom through the water inlet 401, flows from front to back along the lower area 402, and is initially precipitated by multiple sedimentation membrane layers 403; the used wastewater in the lower area 402 passes through multiple lower inclined channels 4101, the middle space 406 and the multiple upper inclined channels 4091 from top to bottom, undergoes secondary precipitation to form reclaimed water, and the reclaimed water is formed in the upper area 405 and enters the water supply pipe through the water outlet 404.

[0058] By arranging the longitudinal water inlet 401, it is convenient for the waste water to enter the lower area 402. When the waste water flows in the lower area 402, it is elastically blocked by multiple sedimentation membrane layers 403, so that the waste water can be preliminarily precipitated.

[0059] The used wastewater in the lower area 402 passes through the lower inclined channel 4101, enters the middle space 406, and then passes through the upper inclined channel 4091. Moreover, the lower inclined channel 4101 and the upper inclined channel 4091 are arranged with different inclinations. Therefore, in the process of the used wastewater passing through from bottom to top, the used wastewater can be blocked in multiple directions, thereby subjecting the used wastewater to secondary sedimentation treatment.

[0060] In this embodiment, two transverse membrane layers 407 are disposed in the central space 406. The two transverse membrane layers 407 are spaced apart vertically to form an elastic spacer. The transverse membrane layers 407 are provided with a plurality of longitudinal through holes extending vertically therethrough. The elastic spacer is provided with a plurality of elastic limiting columns 408. The ends of the limiting columns 408 are connected to the two transverse membrane layers 407, respectively.

[0061] In the process of using wastewater to pass through the two transverse membrane layers 407 from bottom to top, the wastewater passes through multiple longitudinal through holes and elastic gaps, driving the two transverse membrane layers 407 to elastically deform, and the limiting column 408 to elastically deform, so that the wastewater forms a pressure difference from bottom to top in the middle space 406.

[0062] In this way, when the used wastewater passes through the middle space 406, the two horizontal membrane layers 407 form an elastic barrier to the used wastewater, and the horizontal membrane layers 407 undergo elastic deformation during the blocking process, so that a pressure difference is formed in the used wastewater, which greatly improves the efficiency of the used wastewater surging from the bottom to the top, and can block the sedimentation of the used wastewater.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
