[0008] Preferably, the floating plate is a solid structure, a hollow structure or a structure with a groove on the upper surface. When the floating plate is a hollow structure, a water injection port communicating with the interior is provided on the floating plate.

[0009] Preferably, the floating plate is made of wood, plastic or metal.

[0010] Preferably, the sewage collecting tank has a sediment layer, a liquid layer and a scum layer from bottom to top. The sewage collecting tank is connected to the feed assembly and the discharge assembly respectively.

[0011] The beneficial effects of the present invention are:

[0012] The present invention provides a sewage collection tank scum treatment device, which presses on the scum layer through a floating plate. The scum in the scum layer is soaked with water and settles to the bottom of the tank. It can be directly pumped out with a sewage pump, solving the scum problem without the need for stirring facilities, and preventing odor from being discharged into the atmosphere and polluting the air.

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention. The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations.

[0020] In the present invention, unless otherwise clearly stipulated and limited, terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements.

[0021] Embodiment 1

[0022] like Figure 1 As shown, a scum treatment device for a sewage collection tank of the present embodiment comprises a floating plate 7 which is arranged on the upper surface of a scum layer 6 in a sewage collection tank 1. The sewage collection tank 1 is connected to a feed assembly 2 and a discharge assembly 3 respectively. The feces enter the sewage collection tank 1 from the feed assembly 2. The scum layer 6 is formed by accumulation of scum. The floating plate 7 can move up and down with the rise and fall of the upper surface of the scum layer 6, thereby ensuring that the floating plate 7 always presses the scum layer 6. The floating plate 7 presses the scum of the scum layer 6 into the liquid for a long time to immerse and decompose. The decomposed scum automatically settles to the bottom of the sewage collection tank 1 under the action of gravity to form a scum layer 4. The liquid between the scum layer 4 and the scum layer 6 is a liquid layer 5. The scum and liquid are discharged through the discharge assembly 3.

[0023] The floating plate 7 should be made of corrosion-resistant and anti-aging materials to ensure that it floats on the liquid surface and presses the scum into the liquid at the same time.

[0024] like Figure 2 As shown, the floating plate 7 is a solid structure, and the floating plate 7 is made of a material with a low density such as wood, plastic, etc.

[0025] like Figure 3 As shown, the floating plate 7 is a hollow structure, and the floating plate 7 is a hollow space 71. A water injection port 72 connected to the hollow space 71 is provided on the floating plate 7. Water is filled into the hollow space 71 in the floating plate 7 through the water injection port 72 to increase pressure and stability.

[0026] like Figure 4 As shown, the floating plate 7 is a structure with a groove on the upper surface, and the floating plate 7 is made of metal.

[0027] Embodiment 2

[0028] like Figure 5 As shown, a scum treatment device for a sewage collection tank of this embodiment is based on the first embodiment, and two guide holes are provided on the floating plate 7, and a guide rod 8 is movably provided in each guide hole. The two guide rods 8 are connected to the cover plate 9, and the upper surface of the cover plate 9 is an inclined surface. The cover plate 9 is provided at the upper opening of the sewage collection tank 1, and the area of ​​the cover plate 9 is larger than the area of ​​the upper opening of the sewage collection tank 1. The cover plate 9 is supported by the top of the pool wall of the sewage collection tank 1. When the upper surface of the scum layer 6 rises and falls, the floating plate 7 slides up and down along the guide rod 8, and the floating plate 7 is always kept pressed on the upper surface of the scum layer 6. At the same time, the floating plate 7 shields the sewage collection tank 1, and rainwater cannot enter the sewage collection tank 1.

[0029] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the protection scope of the present invention.
