[0019] The following is combined with Figure 1-2 This application is described in further detail.

[0020] The present application discloses a sewage recycling filtering and sedimentation device, referring to Figure 1-2, comprising a shell frame 1, in which a sedimentation tank 2, a filter tank 3 and a clean water storage tank 4 are sequentially installed, a first water pump 5 is connected between the sedimentation tank 2 and the filter tank 3, a second water pump 6 and a filter 7 are connected between the filter tank 3 and the clean water storage tank 4, the bottom of the sedimentation tank 2 is funnel-shaped, and a sewage outlet 21 is provided at the bottom of the sedimentation tank 2, the liquid inlet of the first water pump 5 is connected to the side of the sedimentation tank 2, the liquid outlet of the first water pump 5 is connected to the top side of the filter tank 3, the liquid inlet of the second water pump 6 is connected to the side of the filter tank 3, the liquid outlet of the second water pump 6 is connected to the filter 7, and the liquid outlet of the filter 7 is connected to the clean water storage tank 4;

[0021] The filter tank 3 is provided with multiple oil-blocking assemblies and multiple filter screens 35, and the oil-blocking assemblies and the filter screens 35 are spaced apart. The oil-blocking assembly includes a high-position baffle 31 and a low-position baffle 32 spaced apart on the left and right. The bottom of the low-position baffle 32 is fixed on the bottom wall of the filter tank 3, the high-position baffle 31 is arranged on the top of the low-position baffle 32, and a water passage 33 is formed between the bottom of the high-position baffle 31 and the bottom wall of the filter tank 3. The filter screen 35 is detachably installed in the filter tank 3. A card slot 34 is fixed on the side wall of the filter tank 3 corresponding to the filter screen 35, and the filter screen 35 is matched and carded in the card slot 34. The bottom of the filter tank 3 is connected with multiple sewage pipes 36, and the bottom ends of the multiple sewage pipes 36 are connected with a total waste pipe.

[0022] In order to ensure a good filtering effect, the meshes of the filter screen 35 are different. The meshes of the filter screen 35 on the side close to the sedimentation tank 2 are larger than the meshes of the filter screen 35 on the side close to the clean water storage tank 4.

[0023] Reference Figure 1 In order to facilitate cleaning of the clean water storage tank 4, a cleaning drain pipe 41 is provided at the bottom of the clean water storage tank 4, and a valve is installed on the drain pipe 41.

[0024] The implementation principle of a sewage circulation filtering and sedimentation device according to the embodiment of the present application is as follows:

[0025] When the sewage enters the sedimentation tank 2, the larger impurities in the sewage will settle to the funnel-shaped bottom of the sedimentation tank 2 for preliminary sedimentation. The settled water is sent to the filter tank 3 by the first pump 5. During the movement from left to right in the filter tank 3, the impurities suspended in the water can be filtered again through the multi-pass filter screen 35. Among them, the mesh of the filter screen 35 gradually becomes smaller, and filtering is performed layer by layer to obtain relatively clean water. At the same time, in this process, water passes through the water channel 33, and the oil floating on the surface of the sewage will be blocked by the high-level baffle 31, which can achieve degreasing. Finally, the relatively clean water is sent to the filter 7 by the second pump 6 for filtration again. The water coming out of the filter 7 can meet the requirements of recycling and enters the clean water storage tank 4 for use.

[0026] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
