[0023] 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.

[0024] Reference Figure 1 and Figure 2An embodiment of this utility model provides an artificial bar screen device for sewage treatment, comprising a sewage pipe 1, a support frame 2 fixedly connected to the top of the sewage pipe 1, a first motor 3 fixedly connected to the top of the support frame 2, a rotating shaft 4 fixedly connected to the drive end of the first motor 3, a first bevel gear 5 fixedly connected to both sides of the outer wall of the rotating shaft 4, a second bevel gear 6 meshing with the outer wall of the first bevel gear 5, a first lead screw 7 fixedly connected to the bottom end of the second bevel gear 6, the outer wall of the top of the first lead screw 7 rotatably connected to the inner wall of the top of the support frame 2, the outer wall of the bottom end of the first lead screw 7 rotatably connected to the inner wall of the bottom end of the sewage pipe 1, a bar screen body 8 threadedly connected to the outer wall of the first lead screw 7, grooves 9 being provided on both sides of the inner wall of the sewage pipe 1 and the support frame 2, the outer wall of the bar screen body 8 being slidably connected to the inner wall of the grooves 9, a collection box 18 fixedly connected to the bottom side of the inner wall of the left end of the sewage pipe 1, and a baffle 19 slidably connected to the top of the collection box 18.

[0025] Specifically, both the first motor 3 and the second motor 10 can rotate in both directions. When the first motor 3 drives the grille body 8 to rise and fall, the first motor 3 will rotate in the opposite direction next time. The middle part of the grille body 8 is solid, and the first lead screw 7 is threadedly connected to this part. The sliding groove 9 opened in the support frame 2 and the sewage pipe 1 restricts the movement of the grille body 8, allowing it to move in a straight line. The first lead screw 7 has a self-locking property, so that the rising grille body 8 will not fall down. The top of the support frame 2 is fixed with a support block, which supports the rotating shaft 4. When the grille body 8 on one side is raised for cleaning, the baffle 19 is pulled open first. At this time, the garbage intercepted when the grille body 8 rises will enter the collection box 18 along the sewage pipe 1 for later centralized cleaning. The garbage entering the collection box 18 will stay, and the sewage will go out from the filter screen on the outer wall. When the other side of the grille body 8 falls, the baffle 19 can be pushed back to its original position to close the collection box 18.

[0026] Reference Figure 3 and Figure 4 The support frame 2 has a second lead screw 11 rotatably connected to both the left and right sides of its inner wall. The second lead screw 11 has a slider 12 threadedly connected to its outer wall. The slider 12 is slidably connected to the inner wall of the front end of the support frame 2. The rear end of the slider 12 is rotatably connected to a rotating shaft 13. The outer wall of the rotating shaft 13 is fixedly connected to a cleaning brush 14. The cleaning brush 14 is located at opposite ends of the left and right side grid bodies 8. The rear end of the rotating shaft 13 is fixedly connected to a rotating gear 15. The outer wall of the rotating gear 15 is meshed with a toothed plate 16. The outer wall of the toothed plate 16 is fixedly connected to the inner wall of the rear end of the support frame 2. The top of the sewage pipe 1 has three sludge troughs 17. The left and right side grid bodies 8 are located in the middle of the three sludge troughs 17. The top of the support frame 2 has a second motor 10 fixedly connected to both the left and right sides of its top end. The top of the second lead screw 11 is fixedly connected to the drive end of the second motor 10.

[0027] Specifically, two of the three slag troughs 17 are located on the outer sides of the left and right sides of the grid body 8, and the other is located in the middle. When the cleaning brush 14 cleans up the slag, the slag will fall into the slag trough 17 for later centralized cleaning. The support frame 2 has notches at both the front and rear, which facilitates cleaning of the middle slag trough 17. When the slider 12 drives the rotating shaft 13 to move, a block rotates on the outer wall of the other side of the rotating shaft 13. This block slides on the inner wall of the support frame 2 to support the rotating shaft 13.

[0028] Working principle: During use, sewage flows through sewage pipe 1. The screen body 8 intercepts solid impurities, while the sewage continues to flow through the gaps in the screen bars to the subsequent treatment unit. As sewage continues to flow in, the intercepted screen residue gradually accumulates on the screen bars, requiring cleaning. The first motor 3 is started, which drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the first bevel gears 5 on both sides to rotate, and the first bevel gears 5 drive the second bevel gears 6 to rotate, thereby rotating the first lead screw 7. This causes the screen body 8 on sewage pipe 1 to descend into sewage pipe 1 to continue interception, while the screen body 8 in sewage pipe 1 moves out of sewage pipe 1 and into the support frame 2. Then, the second motor 10 is started, which drives the second lead screw 11 to rotate. The second lead screw 11 drives the slider 12 to move, thereby moving the rotating shaft 13. The rotating shaft 13 drives the cleaning brush 14 to move on the screen body 8. At the same time, the rotating shaft 13 rotates as it moves on the toothed plate 16 through the rotating gear 15, causing the cleaning brush 14 to rotate during its movement, cleaning the screen body 8.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
