[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1-Figure 4 As shown, in order to solve the problem that traditional plate-shaped or cylindrical filter screens are easily clogged by particulate matter during the sewage treatment filtration process and require high-frequency cleaning and replacement, the utility model proposes a water resource recycling device comprising: a spherical shell 10, which is assembled from two hemispherical shells, a sealing strip is arranged at the position of the contact surface, and is connected by bolting, a water inlet pipe 11 is arranged on one side of the spherical shell 10, and a reserved opening 12 is arranged in the middle of the front side of the spherical shell 10; a filtering unit 20, comprising a frame rotatably arranged in the spherical shell 10 and a spherical filter screen 23 sleeved on the frame, the filter screen 23 divides the inner cavity of the spherical shell 10 into two chambers, the spherical shell 10 is connected to a slag discharge pipe 13, one end of the rotating shaft 21 included in the frame passes through the reserved opening 12, and the rotating shaft 21 is provided on the frame. A fluid channel connected to the outside of the spherical shell 10 is provided on the shaft 21. The filter screen 23 and the frame rotate under the impact of the water flow from the water inlet pipe 11. The water flows into a chamber of the spherical shell 10 through the water inlet pipe 11, and the filter screen 23 and the frame are pushed to rotate under the action of inertia. A part of the water flows into the inner side of the filter screen 23 and is discharged through the fluid channel, and another part of the water flows back through the filter screen 23 under the action of inertia and enters another chamber. With the rotation of the filter screen 23, the filter screen can be backwashed while filtering, thereby collecting large particles in the front chamber, and small particles of impurities are collected in the rear chamber after backwashing. This design can greatly reduce the cleaning frequency of the filter screen 23.

[0029] Furthermore, in order to realize the formation of two separated chambers between the filter screen 23 and the inner wall of the spherical shell 10, a holder 14 is integrally formed on the inner side of the spherical shell 10. The holder 14 is vertically arranged in a disc shape, and the inner peripheral surface of the holder 14 is a concave curved surface. The inner peripheral surface of the holder 14 is also provided with an axial hole 142, and the other end of the rotating shaft 21 is rotatably inserted in the axial hole 142. The frame body also includes a plurality of arc-shaped support frames 22, and the two ends of the support frames 22 are fixedly connected to the side walls of the rotating shaft 21. The filter screen 23 is sleeved on the plurality of arc-shaped support frames 22, and the filter screen 23 is rotatably fitted with the inner peripheral surface of the holder 14. The purpose of setting the holder 14 is not only to cooperate with the filter screen 23 and the spherical shell 10 to form two separated chambers, but the holder 14 can also scrape off the particulate impurities extending out of the mesh on the surface of the filter screen 23, and automatically clean it by driving the water flow.

[0030] In the previous step, the two chambers are respectively the front chamber and the rear chamber formed between the spherical shell 10 and the filter screen 23 on both sides of the base 14. The front chamber is connected to the front slag discharge pipe 131, and the rear chamber is connected to the rear slag discharge pipe 132. Large particles of impurities are deposited in the front chamber, and small particles of impurities, that is, impurities placed in the mesh of the filter screen 23, are recoiled and fall off by part of the inertial motion of the water flow, and finally deposited in the rear chamber. It is only necessary to regularly open the front slag discharge pipe 131 and the rear slag discharge pipe 132 to discharge them.

[0031] Furthermore, the fluid channel includes a drain channel 211 opened in the rotating shaft 21, and the drain channel 211 passes through one end of the rotating shaft 21, that is, the rotating shaft 21 passes through one end of the spherical shell 10, and this end is connected to the outer pipe through a rotating joint. A plurality of drain ports 212 are also opened on the rotating shaft 21, and the plurality of drain ports 212 are connected to the drain channel 211. Part of the water flowing into the filter 23 enters the drain channel 211 through the drain port 212 and is finally discharged.

[0032] In the previous step, several drain ports 212 are distributed in a ring shape, and the center of the ring coincides with the center of the spherical shell 10. This design aims to prevent the impact of water flow from generating an axial force on the rotating shaft 21, reduce wear, ensure the stability of equipment operation, and at the same time ensure the homogeneity of recoil.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
