[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a sewage treatment and purification device comprises a shell 1, a filtering mechanism 2 is provided on the top of the shell 1, the filtering mechanism 2 comprises a water outlet 5, the bottom of the water outlet 5 is fixedly connected to the shell 1, the bottom of the shell 1 is fixedly connected to the sewage outlet 3, one side of the shell 1 is fixedly connected to the water inlet 4, the inner side of the shell 1 is fixedly connected to the net cylinder 8, the inner side of the net cylinder 8 is provided with a guide plate 7, the top of the guide plate 7 is fixedly connected to the limit block 11, the bottom of the limit block 11 is rotatably connected to the net cylinder 8, and the top of the limit block 11 is fixedly connected to the impeller 9.

[0023] In this embodiment, the inner side of the water outlet 5 is fixedly connected to the filter screen 6 , and the inner side of the water outlet 5 is fixedly connected to the guide ring 10 .

[0024] The filter screen 6 can intercept the water flow for a second time, so that larger impurities in the water flow are intercepted, thereby increasing the purification effect.

[0025] In this embodiment, the outer diameter of the guide ring 10 matches the inner diameter of the water outlet 5 , and the cross section of the guide ring 10 is wing-shaped.

[0026] The guide ring 10 can guide the passing water flow to move along the inside of the water outlet 5 , so that the water flow carries impurities along the inner wall of the water outlet 5 .

[0027] In this embodiment, the filter screen 6 is funnel-shaped, and its outer diameter matches the inner diameter of the water outlet 5 .

[0028] The filter screen 6 can intercept impurities moving along the inner wall of the water outlet 5, allowing the water flow in the middle to pass through, thereby reducing the impact on the flow rate.

[0029] In this embodiment, a through hole is opened on the top of the net tube 8, and a plate-shaped protrusion is provided on the inner side of the outer shell 1.

[0030] The housing 1 is connected to the mesh tube 8 via a plate-shaped protrusion, so that the mesh tube 8 is fixed and can withstand the impact of water flow. The bottom of the limit block 11 passes through the through hole at the top of the mesh tube 8 and is connected to the guide plate 7, which has mesh holes.

[0031] In this embodiment, circular holes are formed at the bottom and the top of the shell 1 , and a circular hole is formed at one side of the shell 1 , and a circular hole is formed at one side of the net cylinder 8 as well.

[0032] One end of the water inlet 4 passes through the circular hole of the outer shell 1 and is connected to the mesh cylinder 8, and the sewage is injected into the interior of the mesh cylinder 8 and filtered. The water flows through the circular hole on the top of the outer shell 1 and enters the water outlet 5. After the sewage outlet 3 is opened, the water flow can bring impurities into the sewage outlet 3 through the circular hole at the bottom, thereby cleaning the accumulated impurities.

[0033] In this embodiment, a plurality of regular polygonal holes are opened on the outside of the mesh cylinder 8, and a circular hole is opened on the bottom of the mesh cylinder 8. The guide plate 7 has a spiral shape, and a circular protrusion is provided on the top of the guide plate 7.

[0034] The guide plate 7 can transfer the filtered impurities to the bottom of the housing 1 to prevent the impurities from blocking the mesh tube 8 and affecting the filtering effect.

[0035] It should be noted that the utility model is a sewage treatment and purification device, which can filter and intercept sewage twice when in use, and can prevent impurities from clogging the device. The specific implementation method is to inject sewage into the interior of the net cylinder 8 from the water inlet 4. After the sewage enters the interior of the net cylinder 8, it flows out through the mesh of the net cylinder 8 until the interior of the shell 1 is filled, and then discharged from the water outlet 5;

[0036] When the water flows through the mesh cylinder 8, the impurities carried therein will be intercepted by the mesh cylinder 8, and thus stay inside the mesh cylinder 8, so that the water flows through it can be filtered. After passing through the mesh cylinder 8, the water flows into the inside of the water outlet 5 through the circular hole on the top of the shell 1, and drives the impeller 9 to rotate during the flow. When the impeller 9 rotates, it drives the guide plate 7 to rotate. The guide plate 7 is constrained by the mesh cylinder 8 and the limit block 11, so it can only rotate in the original position after being subjected to force. When the guide plate 7 rotates, the impurities intercepted by the mesh cylinder 8 are transported to the bottom of the shell 1 through the spiral shape, and are accumulated at the bottom to prevent the mesh cylinder 8 from being blocked. When the guide plate 8 rotates, it intercepts impurities through its own mesh holes and allows the water to pass through.

[0037] When the water flows through the impeller 9, the impeller 9 rotates, causing the water to flow in a spiral shape. When the water flows through the guide ring 10, under the effect of the shape of the guide ring 10, a pressure difference is formed between the water flow at the inner wall of the water outlet 5 and the water flow at the center thereof. Under the effect of the Bernoulli principle and the impeller 9, the water flows in a spiral toward the inner wall of the water outlet 5, causing the impurities carried to move along the inner wall of the water outlet 5 under the effect of centrifugal force and inertia, and be intercepted by the filter screen 6 during the movement, thereby performing secondary filtration on the water flow.

[0038] By setting up the filtering mechanism 2, the purification device can filter the sewage twice, and can collect impurities in the mesh tube 8 through the action of water flow to avoid affecting the filtering effect of the device, extend the service life of the device and ensure the filtering effect.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
