[0018] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. The components of the embodiments of the invention described and illustrated herein can generally be arranged and designed in various different configurations.

[0019] In this invention, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0020] like Figure 1 and Figure 2 As shown, a centrifugal dewatering system for treating sludge and wastewater according to this embodiment includes a rotating shaft 1, which is connected to a drive unit. The rotating shaft 1 is mounted on a support via two bearings 10. An outer cylinder 2 and a turntable 3 are provided on the rotating shaft 1. The outer cylinder 2 is located around the turntable 3. The outer cylinder 2 is approximately frustum-shaped. The diameter of the outer cylinder 2 increases from top to bottom. Leakage holes are evenly provided on the outer cylinder 2. Water baffles 4 are provided in a ring on the inner and outer walls of the outer cylinder 2. The water baffles 4 are provided in multiple layers.

[0021] The turntable 3 has multiple layers, and an inner cylinder 9 is mounted on the rotating shaft 1. The inner cylinder 9 is cylindrical, and all the multiple turntables 3 are mounted on the inner cylinder 9. The outer cylinder 2 is connected to the rotating shaft 1 via a connecting rod (not shown in the figure). The synchronous rotation of the outer cylinder 2 makes it easier for sludge and sewage to fall off. The diameter of the turntable 3 increases from top to bottom, and through holes are opened on the turntable 3 to allow sludge and sewage to fall from top to bottom. This ensures that each layer of the turntable 3 carries sludge and sewage and can throw the sludge and sewage onto the outer cylinder 2, improving the dewatering efficiency.

[0022] The upper surface of the turntable 3 is evenly distributed with baffles 5, which protrude from the upper surface of the turntable 3. The turntable 3 rotates in a circular motion during operation. The baffles 5 serve two purposes: first, they prevent the sludge and wastewater on the turntable 3 from flowing circumferentially, allowing the sludge and wastewater to be effectively thrown towards the outer cylinder 2; second, they ensure a more even distribution of the sludge and wastewater falling from the upper turntable. Figure 2 As shown, the baffle 5 has an arc-shaped structure.

[0023] A slag collection plate 6 is provided on the rotating shaft 1. The slag collection plate 6 is located below the outer cylinder 2 and the turntable 3. A water collection plate 7 is provided at the lower end of the outer cylinder 2.

[0024] The support frame is equipped with a conveying pipe, the lower end of which is opposite to the turntable 3. Wastewater mixed with sludge is fed into the turntable 3 through the conveying pipe. The turntable 3 rotates circumferentially under the drive of the rotating shaft 1, throwing the sludge towards the outer cylinder 2. Water is thrown out from the leakage hole, and solid sludge is blocked on the inner wall of the outer cylinder 2 and falls off. The baffle plate 4 can effectively prevent water from flowing back into the outer cylinder 2 through the leakage hole when it falls, thus affecting the dewatering effect. The water falls onto the water collection plate 7 for collection and discharge, and the solid sludge falls onto the sludge collection plate 6. The sludge collection plate 6 also rotates circumferentially under the drive of the rotating shaft 1. Therefore, the solid sludge on the sludge collection plate 6 is discharged from the sludge outlet 8 of the sludge collection plate 6 and the water collection plate 7 under the action of centrifugal force. Through this centrifugal dewatering system, wastewater can be continuously fed in, continuously dewatered, and sludge and liquid can be discharged.

[0025] It should be noted that sludge includes fecal matter, therefore this centrifugal dewatering system is also suitable for treating wastewater mixed with fecal matter.

[0026] like Figure 3 As shown, in another embodiment, the inner cylinder 9 is frustum-shaped.

[0027] like Figure 4 As shown, in another embodiment, the outer cylinder 2 is not provided with a baffle plate 4, but the outer wall of the outer cylinder 2 is a wave-shaped surface with a wave pattern arranged from top to bottom. This arrangement can also prevent water from flowing into the outer cylinder 2 from the leak hole when it falls out.

[0028] In other embodiments, both the turntable 3 and the baffle plate 4 are provided with only one layer, and no through holes are provided on the turntable 3.

[0029] This invention is not limited to the above-described optional embodiments. Anyone can derive other various forms of products under the guidance of this invention. However, regardless of any changes made in their shape or structure, any technical solution that falls within the scope of the claims of this invention shall be protected by this invention.
