DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0018] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0019] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a solid-liquid pre-separation device for sewage treatment in environmental protection engineering, including a treatment tank 1. At the edge near the top inside the treatment tank 1, an inclined plate 3 is fixedly connected. On the surface of the inclined plate 3, a plurality of filter layers 4 are arranged equidistantly in the horizontal direction. At the edge near the top on the outer surface of one side of the treatment tank 1, a through hole 8 is opened, and the through hole 8 is connected to the inclined plate 3. On the outer surface of one side of the treatment tank 1, below the through hole 8, a separation tank 5 is fixedly connected. Near the center inside the separation tank 5, a separation plate 6 is fixedly connected. On the top of the separation plate 6, separation filter layers 7 are arranged equidistantly in the horizontal direction. Then it slides on the inclined plate 3. During the sliding process, the liquid on the surface will enter through the filter layer 4, so that part of the solid-liquid can be effectively separated. The remaining part will directly flow into the separation tank 5 by rolling. Inside the separation tank 5, solid-liquid separation can be carried out through the separation plate 6. The liquid part will flow into the inside of the separation tank 5 through the separation filter layer 7. After accumulating the liquid in the separation tank 5, however, the solid will be formed on the surface of the separation tank 5, thus facilitating treatment and improving the use effect of the device.

[0020] At the center near the top of the treatment tank 1, a feed inlet 2 is fixedly connected in communication. Through the feed inlet 2, the sewage to be treated can be input.

[0021] One side of the separation tank 5 is connected with a circulation pipeline 9, and one end of the circulation pipeline 9 extends into the inside of the treatment tank 1. Through the continuous circulation of the circulation pipeline 9, the liquid is collected and summarized inside the collection tank 10.

[0022] On the inner bottom surface of the treatment tank 1, a collection tank 10 is slidably connected, and the collection tank 10 is located below the circulation pipeline 9. The collection by the collection tank 10 facilitates the treatment after separation.

[0023] On the outer surface of the front side of the collection tank 10, near the edges on both sides, fixed blocks 11 are fixedly connected. Between the outer surfaces of the front sides of the two fixed blocks 11, a pull rod 12 is fixedly connected. Through the pull rod 12, the fixed block 11 can drive the collection tank 10 to slide, so that the collection tank 10 is convenient for treatment.

[0024] At the four corners near the bottom of the treatment tank 1, buffer blocks 13 are fixedly connected. Near the center at the bottom of the four buffer blocks 13, support rods 14 are fixedly connected. Through the fixation of the buffer blocks 13, the support effect of the support rods 14 is better.

[0025] Working principle: When the device is in use, first, the sewage to be treated can be fed through the feed inlet 2, and then it slides on the inclined plate 3. During the sliding process, the liquid on the surface will pass through the filter layer 4, so that part of the solid-liquid can be effectively separated. The remaining part will directly flow into the separation tank 5 by rolling. Inside the separation tank 5, solid-liquid separation can be carried out through the separation plate 6. The liquid part will flow into the inside of the separation tank 5 through the separation filter layer 7. After the liquid accumulates in the separation tank 5, it continuously circulates through the circulation pipeline 9, so that the liquid is collected and summarized inside the collection tank 10. However, the solid will be formed on the surface of the separation tank 5, which is convenient for treatment and improves the use effect of the device.

[0026] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
