Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and more specifically to a wastewater treatment device for treating black water. Background Technology
[0002] Black water, also known as fecal wastewater, has two main definitions: first, it refers to domestic sewage containing fecal matter; second, it refers to toilet wastewater, including flushing wastewater and feces. Additionally, "night soil" refers to black water that contains little or no flushing water (in building water supply and drainage, water quality can be figuratively classified as white water, grey water, and black water; tap water is called white water, grey water refers to water used for showering and washing, and wastewater containing feces is called black water). Every household generates black water containing feces. In agriculture, water containing feces can be used to irrigate farmland, providing excellent fertilization. However, current black water utilization methods often lack filtration and disinfection, leading to direct irrigation with black water. Black water frequently contains non-biodegradable plastics, resulting in plastic residues in the soil, which can negatively impact crop growth. Therefore, developing a black water treatment and utilization device with filtration capabilities is crucial.
[0003] Therefore, how to provide a wastewater treatment device for black water treatment that can treat and utilize black water is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] See Figure 1-3 This utility model discloses a wastewater treatment device for black water treatment, comprising:
[0029] The cylinder 1 has an inlet 2 at its top and an outlet 3 on its side wall. In this embodiment, the cylinder 1 is used to store black water and provide space for black water treatment. The inlet 2 is connected to an external suction device to draw sewage into the cylinder 1.

The top of the vertical shaft 4 extends out of the cylinder 1, and a motor 5 is installed at the top of the cylinder 1. The vertical shaft 4 is connected to the motor 5 via a transmission connection. In this embodiment, the vertical shaft 4 extends vertically through the top of the cylinder 1. The portion of the vertical shaft 4 outside the cylinder 1 is used for a fixed connection to the output shaft of the motor 5. The portion of the vertical shaft 4 inside the cylinder passes through the grinding disc 6 and the filter hopper 8 from top to bottom. The rotation of the vertical shaft 4 drives the grinding disc 6 and the filter hopper 8 to rotate. The axis of the vertical shaft 4 is aligned with the axis of the cylinder 1 and the straight lines of the grinding disc 6 and the filter hopper 8.
[0031] The grinding disc 6 is sleeved on the vertical shaft 4 and rotates synchronously with the vertical shaft 4. A first vertical hole 7 is vertically provided through the grinding disc 6. In this embodiment, the grinding disc 6 rotates in the cylinder 1. When in use, the stirring roller 10 on the grinding disc 6 rotates around the stirring shaft 11. The grinding disc 6 rotates below the stirring roller, thereby enabling the grinding of black water and impurities in the black water. The ground black water and impurities flow to the bottom of the grinding disc 6 through the first vertical hole 7.
[0032] A filter hopper 8 is positioned below the grinding disc 6 and fitted onto the vertical shaft 4. The filter hopper 8 rotates synchronously with the vertical shaft 4. A second vertical hole 9 is vertically penetrating the filter hopper 8. In this embodiment, the filter hopper 8 is a conical structure with the tip pointing downwards. The stirring rod on the filter hopper 8 is inclined and can cooperate with the upper surface of the filter hopper 8. The filter hopper 8 can filter impurities in the black water. Larger particles of impurities will move towards the edge of the filter hopper 8 under the action of centrifugal force, while smaller particles of impurities will enter the cylinder 1 below the filter hopper 8 through the second vertical hole 9. The diameter of the second vertical hole 9 is smaller than the diameter of the first vertical cylinder.
[0033] A stirring roller 10 is provided, and multiple stirring rollers 10 are respectively provided on the upper surface of the filter hopper 8 and the grinding disc 6. A stirring shaft 11 is provided through the middle of the stirring roller 10, and one end of the stirring shaft 11 is fixedly connected to the side wall of the cylinder 1. In this embodiment, the stirring roller 10 is used to stir and grind the impurities on the filter hopper 8 and the grinding disc 6, which can process the larger volume impurities into smaller volume impurities, and can also fully stir the black water.
[0034] A stirring rod 12 is mounted on a vertical shaft 4 below the filter hopper 8, and the stirring rod 12 rotates synchronously with the vertical shaft 4. In this embodiment, the cylinder 1 below the filter hopper 8 is filled with disinfectant, and the stirring rod 12 is rotated by the vertical shaft 4 to make the black water and disinfectant fully mixed.
[0035] A collection hopper 13 is provided on the outer wall of both the grinding disc 6 and the filter hopper 8. The collection hopper 13 is ring-shaped and the two collection hoppers 13 are respectively fitted on the outer wall of the grinding disc 6 and the filter hopper 8. In this embodiment, the collection hopper 13 is used to collect larger impurities that the grinding disc 6 cannot grind or filter. The impurities move toward the collection hopper 13 under the action of centrifugal force.
[0036] A sedimentation tube 14 is provided at the bottom of the filter bucket 8. The top of the sedimentation tube 14 is connected to the collection bucket 13 on the outer wall of the filter bucket 8. The outlet 3 is located below the collection bucket 13 on the outer wall of the filter bucket 8. The bottom of the sedimentation tube 14 is located in the cylinder 1 below the outlet 3. Both the top and bottom of the sedimentation tube 14 are provided with openings. In this embodiment, the top of the sedimentation tube 14 is sealed to the bottom of the collection bucket 13. The sedimentation tube 14 is filled with disinfectant. When in use, black water enters the sedimentation tube 14 from the top and flows out of the sedimentation tube 14 from the bottom. Impurities in the black water settle in the cylinder 1 below the sedimentation tube 14. The settled black water flows out of the cylinder 1 through the outlet 3. The outlet 3 is located above the outlet 3 of the sedimentation tube 14.
[0037] A bushing 15 is provided on the vertical shaft 4. One end of the stirring shaft 11 is fixedly connected to the cylinder 1, and the other end of the stirring shaft 11 is fixedly connected to the outer wall of the bushing 15. In this embodiment, a bearing is provided on the inner wall of the bushing 15 on the vertical shaft 4. The vertical shaft 4 rotates while the bushing 15 remains stationary.
