[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0028] Reference Figure 1-Figure 4 This invention relates to a treatment device for deep oxidation of industrial wastewater, used in the field of wastewater treatment technology. The device comprises a wastewater tank 1, an inverted U-frame 2, a reciprocating assembly, an extrusion assembly, and a stirring assembly. In practice, the wastewater tank 1 serves as the main container for the industrial wastewater to be treated. The inverted U-frame 2 is positioned above the wastewater tank 1 and has two feed ports 14 within it. Each feed port 14 houses a barrel 8 for storing an oxidant.

[0029] A first groove 3 is defined on either side of the wastewater tank 1. A reciprocating screw 4 is rotatably mounted in one groove, while a slide bar 5 is fixed in the other. The bottom of the inverted U-frame 2 is equipped with slideways that match these grooves, allowing it to slide smoothly along the slide bar 5 and is threadedly connected to the reciprocating screw 4. A reciprocating motor 6 is fixed to one side of the wastewater tank 1 and connected to the reciprocating screw 4 via a coupling. This reciprocating motor drives the inverted U-frame 2 to reciprocate along the length of the wastewater tank 1, ensuring uniform oxidant delivery.

[0030] Each barrel 8 is fitted with a hollow plate 20. A limit rod 21 is slidably mounted within the hollow plate 20, with a sealing plate 23 fixed to the bottom of the limit rod 21. A sealing ring 24 is mounted on the inner wall of the barrel 8, cooperating with the sealing plate 23 to form a seal. A sealing spring 22 is installed between the sealing plate 23 and the hollow plate 20 and sleeved on the limit rod 21 to ensure a tight seal.

[0031] A third groove 18 is provided in the inverted U-frame 2 corresponding to each barrel 8 position, and an extrusion block 19 is slidably installed inside. A trapezoidal block 25 is fixed to the bottom of the sealing plate 23, forming an extrusion contact with the extrusion block 19. The extrusion block 19 is connected to the extrusion rod 11 in the second groove 15 through a connecting rod 17. A fixed rod 9 is fixed to the side end of the wastewater tank 1, on which a plurality of arc-shaped protrusions 10 are evenly distributed. When the inverted U-frame 2 reciprocates, the extrusion rod 11 moves between the arc-shaped protrusions 10, and pushes the extrusion block 19 up or down through the connecting rod 17 thereon, thereby controlling the opening and closing of the sealing plate 23 to achieve the quantitative release of the oxidant; after the extrusion rod 11 leaves the extrusion of the arc-shaped protrusion 10, it is pushed back to its original position by the elastic force of the positioning spring 16. After the sealing plate 23 and the trapezoidal block 25 lose their extrusion, the sealing spring 22 drives the sealing plate 23 to fit the sealing ring 24 again to seal the barrel 8, and intermittent unloading is carried out in this way. Example

[0032] refer to Figure 1-Figure 4 , based on the improvement of Example 1: a stirring motor 7 is fixed on the top of the inverted U-frame 2 and connected to the stirring shaft 12 through a coupling. A plurality of stirring blades 13 are evenly fixed on the stirring shaft 12. When the stirring motor 7 is started, the stirring blades 13 rotate, fully mixing the wastewater and the oxidant, thereby improving the oxidation efficiency.

[0033] However, as is well known to those skilled in the art, the working principles and wiring methods of the reciprocating motor 6 and the stirring motor 7 are commonplace, and are conventional means or common knowledge, so they will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0034] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
