[0023] Please refer to Figures 1-5 , the present invention provides a technical solution: a straight cylindrical waste water filtering mechanism, including a cylinder body 1, an arc-shaped cover plate 2 and a circular filter screen plate 3;

[0024] Flanges 4 are provided at both ends of the cylinder body 1, and a number of reinforcing plates 14 are evenly provided at both ends of the cylinder body 1. The reinforcing plates 14 are also connected to the flanges 4 to ensure the structural strength at the flanges 4. A groove 5 is opened on the upper surface of the middle position of the cylinder body 1. Three first semi-circular grooves 6 are opened on the inner wall of the cylinder body 1 at the position of the groove 5. Waste discharge ports 7 are provided on the lower surface of the cylinder body 1 on the water inlet direction side of the first semi-circular grooves 6. A backwash port 8 is provided on the upper surface of the cylinder body 1 near the water outlet direction side. First connecting plates 9 are provided on both sides of the cylinder body 1 at the position of the groove 5;

[0025] On both sides of the arc-shaped cover plate 2, there are second connecting plates 10. The arc-shaped cover plate 2 is arranged at the groove 5 of the cylinder body 1. The second connecting plates 10 are connected to the first connecting plates 9 through bolts and nuts. The outer surface of the arc-shaped cover plate 2 is flush with the outer surface of the cylinder body 1, making the whole waste water filtering mechanism a cylindrical structure. At both ends of the arc-shaped cover plate 2, there are arc-shaped grooves 12 opened. On both sides of the arc-shaped cover plate 2, there are also strip-shaped grooves 13 opened. Sealing strips are filled in both the strip-shaped grooves 13 and the arc-shaped grooves 12. The installation of the sealing strips is realized through the arc-shaped grooves 12 and the strip-shaped grooves 13, so as to ensure the sealing performance of the connection between the arc-shaped cover plate 2 and the groove 5 of the cylinder body 1 and avoid water leakage. On the inner wall of the arc-shaped cover plate 2, there is a second semi-circular groove 11, and the second semi-circular groove 11 corresponds to the first semi-circular groove 6 one by one to form an annular groove;

[0026] There are several circular filter plates 3, and the circular filter plates 3 are respectively arranged in the corresponding annular grooves formed by the first semi-circular groove 6 and the second semi-circular groove 11.

[0027] As Figure 6 shown, the circular filter plate 3 includes a ring body 301 and a filter screen 302. There are two ring bodies 301 which are connected by bolts and nuts in cooperation. The outer edge of the filter screen 302 is clamped between the two ring bodies 301. While realizing the waste water filtration, the circular filter plate 3 with this structure can only replace the filter screen 302, saving the use cost.

[0028] Usage method and principle: First, insert the circular filter plates 3 with different mesh numbers into the first semi-circular groove 6 of the cylinder body 1. The mesh number is larger near the water inlet end and smaller near the water outlet end. Then, cover the arc-shaped cover plate 2 and connect the first connecting plate 9 and the second connecting plate 10 through bolts and nuts to complete the assembly. During use, connect two pipes to the flanges 4 at both ends of the cylinder body 1 respectively, and make the waste discharge port 7 face downward. When the wastewater passes through the filtering mechanism, the filter residue particles in the wastewater are blocked by the filter screen 302 of the circular filter plate 3. During normal use, the valves at the waste discharge port 7 and the backwashing port 8 are both in the closed state. When it is necessary to clean the filter residue particles, close the pipes at both ends through valves, open the valves at the waste discharge port 7 and the backwashing port 8, and perform backwashing through the backwashing port 8. Most of the filter residue particles are discharged from the waste discharge port 7. When it is necessary to disassemble, clean or replace the circular filter plate 3, just remove the arc-shaped cover plate 2. The structure of the present utility model is reasonable. It can be directly connected to the pipe through the flanges 4 at both ends of the cylinder body 1, which is convenient for installation and can be smoothly adapted to the pipe. Three first semi-circular grooves 6 and second semi-circular grooves 11 are respectively arranged on the inner wall of the cylinder body 1 and the inner wall of the arc-shaped cover plate 2. Three circular filter plates 3 with gradually decreasing mesh numbers can be sequentially installed inside the cylinder body 1, so as to achieve step-by-step filtration. Moreover, waste discharge ports 7 are arranged on the lower surface of the cylinder body 1 and on the water inlet direction side of the first semi-circular groove 6, and a backwashing port 8 is arranged at one end of the upper surface of the cylinder body 1 and near the water outlet direction side. Through the cooperation of the backwashing port 8 and the waste discharge port 7, backwashing can be carried out to discharge most of the filter residue particles, saving the cleaning time. And when replacing the circular filter plate 3, just remove the arc-shaped cover plate 2, greatly improving the convenience.

[0029] For those parts not detailed in the present utility model, they are all well-known technologies to those skilled in the art.

[0030] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified and equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
