[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 In this embodiment of the present invention, a bar screen for urban sewage treatment includes an installation frame 1. The installation frame 1 has a hollow, U-shaped structure, and a bar screen conveying mechanism is installed on the inner wall of the installation frame 1. A fixed platform 5 is integrally formed on the installation frame 1 away from the water inlet end. A collection box 8 for receiving waste is installed on one end of the fixed platform 5 near the installation frame 1. A waste conveying mechanism is installed on the bottom of the inner wall of the collection box 8, extending above the fixed platform 5. The bar screen conveying mechanism and the waste conveying mechanism are connected by a synchronous mechanism. A plurality of drainage holes 12 are equidistantly opened on the bottom plate of the collection box 8, and the bottom plate of the collection box 8 is located above the water surface.

[0019] In this embodiment: When the bar screen conveyor is running, it lifts the dirt floating on the water surface upward until it reaches the highest point. Then, the bar screen conveyor moves the dirt downward from the highest point. At this time, the dirt detaches from the bar screen conveyor under its own weight and falls into the collection box 8. The water contained in the dirt is discharged outward through the drain hole 12. At this time, the bar screen conveyor drives the garbage conveyor to run synchronously through the synchronization mechanism. The garbage conveyor discharges the dirt that falls into the collection box 8 outward. The collection box 8 can buffer and contain the dirt, preventing a lot of dirt from falling directly onto the garbage conveyor and causing the dirt to fall into the water from both sides of the garbage conveyor. At the same time, since the side opening on the collection box 8 cooperates with the ribs 7, the dirt can be transported outward in an orderly manner.

[0020] It should be noted that the top of the fixed platform 5, located at the end of the waste conveying mechanism, is also equipped with a horizontally set two-stage conveyor belt (not shown in the figure) to output the waste that will be carried out, so as to prevent the waste from falling back into the water.

[0021] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The grid conveying mechanism includes a transmission roller 4 rotatably connected between the upper and lower sides of the inner wall of the mounting frame 1. A first conveyor belt 2 is connected between the two transmission rollers 4. The first conveyor belt 2 has a porous structure. A dredging net 3 is installed at equal intervals on the outer wall of the first conveyor belt 2. The dredging net 3 also has a porous structure.

[0022] In this embodiment: When the rotary motor 17 is running, it drives the transmission roller 4 connected to it to rotate. The transmission roller 4 drives another transmission roller 4 to rotate synchronously through the first conveyor belt 2. During the transmission process of the first conveyor belt 2, it drives the fishing net 3 to move, so that the dirt in the water can be scooped out.

[0023] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The waste conveying mechanism includes a driven roller 13 rotatably mounted on the lower inner wall of the collection box 8, an active roller 15 rotatably mounted on the top of the fixed platform 5, and a pressure roller 14 rotatably mounted on the lower part of the fixed platform 5 via a first rotating seat. A second conveyor belt 6 is connected between the driven roller 13, the pressure roller 14 and the active roller 15. Ribs 7 are evenly distributed on the outer wall of the second conveyor belt 6. The first rotating seat is fixedly mounted on the bottom end of the fixed platform 5. The waste conveying mechanism also includes two limiting rollers 16 fixedly mounted on the lower part of the fixed platform 5 via a second mounting seat. The distance between the two limiting rollers 16 is equal to the length of the ribs 7. The limiting rollers 16 are used to press the bends of the second conveyor belt 6. The second conveyor belt 6 has a porous structure.

[0024] In this embodiment: When the grid conveying mechanism is running, it drives the garbage conveying mechanism to run synchronously through the synchronization mechanism. At this time, the dirt entering the collection box 8 comes into contact with the second conveyor belt 6. The second conveyor belt 6 in the transmission state drives multiple ribs 7 to drive. The dirt falling between two adjacent ribs 7 is carried out, so that the dirt can be discharged from the collection box 8.

[0025] Please refer to this carefully. Figure 2 and Figure 3 The synchronization mechanism includes a large pulley 10 coaxially mounted with a transmission roller 4 and a small pulley 11 coaxially mounted with a drive roller 15. A rotary motor 17 is mounted on the other end of the transmission roller 4. The rotary motor 17 is mounted on the outside of the mounting frame 1 via a mounting bracket. The large pulley 10 and the small pulley 11 are connected by a belt 9. The diameter of the large pulley 10 is larger than the diameter of the small pulley 11.

[0026] In this embodiment: the rotary motor 17 drives a transmission roller 4 connected to it to rotate, which in turn drives a large pulley 10 connected to it to rotate. The rotation of the large pulley 10 drives a small pulley 11 to rotate via the belt 9. At this time, the angular velocity of the small pulley 11 is greater than that of the large pulley 10. Therefore, the rotation speed of the drive roller 15 is greater than that of the transmission roller 4, thereby achieving a transmission speed of the second conveyor belt 6 that is greater than that of the first conveyor belt 2, thus avoiding the problem of dirt accumulating in the collection box 8.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
