[0002] The hydraulic screen is a simple, efficient and easy-to-maintain pollution interception device that uses porous materials to intercept suspended matter in liquids. It is suitable for removing solid suspended impurities from low-concentration solutions and is often used in industrial wastewater treatment such as printing and dyeing wastewater and poultry processing, as well as urban sewage treatment and recovery of useful solid debris. Hydraulic screens are divided into fixed plane hydraulic screens, fixed curved hydraulic screens and hydraulic rotary screens. Among them, for the fixed curved hydraulic screen, since the screen filters impurities in the water body by the impact of water flow on the lower end of the screen, and the existing curved hydraulic screen needs to limit the water flow exit speed and water volume from the top of the screen in order to ensure the falling distance of the water flow, resulting in the inability to effectively improve the slag removal efficiency.

By rotating the positioning tube 15, the distance between the first clamping plate 14 and the second clamping plate 16 can be adjusted, so as to clamp the surface of the water inlet channel 18.

[0022] The bottom of the arc-shaped fixing frame 1 is detachably connected with an impurity collection tank 17 through a card slot 11, and the inner bottom surface of the impurity collection tank 17 has filter holes, which is convenient for discharging the excess water in the impurities.

The top surface of the guide plate 3 is tangent to the top surface of the sieve mesh 2. A chamfered end is formed at the bottom end of the guide plate 3 to facilitate the falling of impurities.

[0024] Preferably, as Figure 1 shown, at the connection between the inverted L-shaped fixing frame 4 and the interception mesh 6, an anti-overflow plate 5 is perpendicularly welded. The length of the anti-overflow plate 5 is not less than the length of the interception mesh 6. The anti-overflow plate 5 can prevent the lateral flow of water.
