The hydraulic screening device does not require workers to remove impurities, which reduces the labor intensity of workers and improves the personal safety of workers.

[0042] Furthermore, the feeding device comprises: an upper screen feeding hopper device 1, an upper screen cone-shaped funnel 2 and an upper screen flushing device 3, the upper screen feeding hopper device 1 is fixed in a supporting rectangular frame by bolts, the large end of the upper screen cone-shaped funnel 2 is connected to the bottom of the upper screen feeding hopper device 1, the upper screen cone-shaped funnel 2 is connected to the upper screen feeding hopper device 1, the upper screen flushing device 3 is connected to the bottom of the upper screen cone-shaped funnel 2, and the bottom of the upper screen flushing device 3 is connected to a homogenizing distributor 15; the staff adds the material to be screened to the upper screen The feeding hopper device 1 enters the upper screen cone funnel 2 through the upper screen feeding hopper device 1. A pneumatic vibrator is connected to the side wall of the upper screen cone funnel 2. The pneumatic vibrator vibrates the material in the upper screen cone funnel 2 to slowly enter the upper screen flushing device 3. The annular water feeder on the side wall of the upper screen flushing device 3 transports water to the upper screen flushing device 3, and the water entering the upper screen flushing device 3 forms a vortex water area to preliminarily flush the material. The flushed material slowly falls into the water screen device through the homogenizer distributor 15.

[0043] Among them, the homogenizer 15 is also called a material distributor or a distributor, which is a device widely used in many industries, especially in the fields of metallurgy, chemical industry, building materials, environmental protection, etc. Its main function is to evenly distribute materials in a certain area to ensure that the subsequent processing process can be more sufficient and uniform, and improve product quality and production efficiency. In terms of structure, the homogenizer usually includes a distribution tank, a driving device, a distribution plate or a distribution roller, etc., and realizes accurate delivery and dispersion of materials by accurately controlling the distribution speed, thickness and uniformity.

[0044] Furthermore, the annular water feeder includes: an annular water feeder A4 and an annular water feeder B5, the annular water feeder A4 and the annular water feeder B5 respectively include an A water inlet 22 and a B water inlet 23 arranged on the side wall of the upper screen flushing device 3, the A water inlet 22 and the B water inlet 23 are arranged on opposite sides of the upper screen flushing device 3, and the ends of the A water inlet 22 and the B water inlet 23 located outside the upper screen flushing device 3 are connected to a water pump, through which a high-pressure water flow can be delivered into the upper screen flushing device 3; the A water inlet 22 and the B water inlet 23 are arranged at an angle to the side wall of the upper screen flushing device 3, for example, it can be 30°~60°, or it can be other degrees, as long as a vortex water area can be formed in the upper screen flushing device 3, the material can be driven to rotate clockwise under the action of hydraulic force, so that the material can be cleaned more cleanly.

The connecting rod mechanism can be four connecting rods 24 movably connected to the side wall of the screen 7, and the other end of the connecting rod 24 is movably connected to the inner wall of the water screen frame 6, so that the screen 7 can swing within a certain range. The side wall of the water screen frame 6 is connected with an outlet 11. After the water-material mixture is transported to the screen 7 through the discharge nozzle 21 of the homogenizer 15, large pieces of paper scraps, impurities, and foreign matter can be smoothly filtered to the outlet position direction by gently swinging the screen 7, which is convenient for manual centralized extraction.

To adjust the water spraying angle of the nozzle 9, water is sprayed on different areas of the screen surface of the screen 7 to clean the screen surface of the screen 7 without dead angles. After being rinsed by the nozzle 9, the finished material falls into the material storage bin 13 through the screen holes of the screen 7. Paper scraps, impurities and foreign matter float on the water surface and fall into the collection box 12 for paper scraps, impurities and foreign matter through the outlet 11 on the side wall of the water screen frame 6. Then the collection box 12 for paper scraps, impurities and foreign matter is opened to discharge the impurities such as paper scraps, impurities and foreign matter inside. The pneumatic valve at the bottom of the material storage bin 13 is opened to discharge the finished material, and then the material can be filtered and dried.
