[0002] A rotary mechanical screen is a device used in sewage treatment systems, primarily for solid-liquid separation and sludge treatment. It typically consists of a rotating cylinder with inclined plates or bars. The rotation separates solid particles from the wastewater, depositing them at the bottom, thereby filtering and removing them. Rotary mechanical screens effectively remove large impurities from wastewater, protecting subsequent equipment from damage, while also helping to improve treatment efficiency and purify water quality. This equipment is commonly used in sewage treatment plants, industrial wastewater treatment systems, and sewage collection systems.

[0003] However, when the rotary mechanical screen machine is cleaning impurities in sewage, it is necessary to allow the sewage to pass through the area below the center of the rotary mechanical screen machine. When the sewage passes through the screen conveyor belt of the rotary mechanical screen machine, the screen conveyor belt can allow the sewage to pass normally, and the garbage impurities in the sewage will be blocked by the screen conveyor belt. When the screen conveyor belt rotates, the blocked garbage impurities will be lifted upward and eventually discharged. However, when the screen conveyor belt rotates, a large amount of impurities with strong adhesion will adhere to the screen conveyor belt. After the position of the impurities with strong adhesion on the screen conveyor belt returns to the front end of the rotary mechanical screen machine, the sewage will pass through this area of ​​the screen conveyor belt, and the garbage impurities adhered to the screen conveyor belt will block the sewage from passing through, which will weaken the rotary mechanical screen machine's blocking and filtering effect on garbage impurities.

Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0021] The utility model provides Figure 1-3The quick-installation rotary mechanical screen machine shown in the figure includes a base 3 and a left side plate 2 arranged at the top of the left end of the base 3, a right side plate 4 is arranged at the top of the right end of the base 3, a top box 7 is connected to the top of the left side plate 2 and the right side plate 4, a screen conveyor belt 5 is arranged inside the left side plate 2, the right side plate 4 and the top box 7, and a plurality of material lifting screens 6 are fixed at equal intervals on the outer wall of the screen conveyor belt 5, a water outlet cover 1 is connected to the rear end of the bottom of the left side plate 2 and the right side plate 4, and the front and rear ends of the water outlet cover 1 are designed with openings to allow water to flow normally, a sewage cover 10 is arranged at the bottom of the rear half of the top box 7, and the sewage cover 10 is connected to the inside of the top box 7, and the outer wall of the lower left end of the center of the left side plate 2 and the outer wall of the lower right end of the center of the right side plate 4 are fixed by bolts. There is a mounting seat 12. When installing the rotary mechanical screen machine, you first need to lift the entire rotary mechanical screen machine through a hoisting machine, and then use the hoisting machine to lift the rotary mechanical screen machine above the reserved window where sewage and garbage need to be filtered. Then you need to lower the rotary mechanical screen machine so that the bottom end of the rotary mechanical screen machine is inserted into the reserved window until the mounting seat 12 on the outer wall of the left side plate 2 and the right side plate 4 fits against the outer wall of the top of the reserved window, and then fix the mounting seat 12 with bolts. This will make the rotary mechanical screen machine firmly installed and fixed, and then you need to connect the power to the transmission motor 8 to make it run, and use the rotary mechanical screen machine normally to separate and clean sewage and garbage.

[0022] like Figure 1As shown, a transmission motor 8 is provided on the top of the top box 7, and a transmission protection cover 9 is connected to the left end of the transmission motor 8 and the left end of the top box 7. A driven transmission roller is provided inside the lower end of the grille conveyor belt 5, and an active transmission roller is provided inside the top of the grille conveyor belt 5. Gears are provided on the outside of the left end of the motor shaft of the transmission motor 8 and the outside of the left end of the transmission shaft of the active transmission roller. The two gears are connected by a transmission chain, and the transmission chain is provided inside the transmission protection cover 9. When the rotary mechanical grille machine is in normal operation, the sewage will be transported from the front to the rear of the rotary mechanical grille machine, so the sewage needs to pass through the lower side of the center of the rotary mechanical grille machine, and the sewage will normally pass through the grille conveyor belt 5 and be discharged backward through the water outlet cover 1. The garbage in the sewage The impurities will be blocked by the grille conveyor belt 5. At the same time, the transmission motor 8 drives the active transmission roller through the transmission chain. The mutual transmission between the active transmission roller and the driven transmission roller will drive the grille conveyor belt 5 to rotate stably, and the garbage impurities blocked by the grille conveyor belt 5 will be retained by the material lifting grille 6. At the same time, the grille conveyor belt 5 will lift the blocked and retained garbage impurities upward through the material lifting grille 6. After the garbage impurities are transported to the inside of the top box 7, the grille conveyor belt 5 will start to rotate, so that the garbage impurities retained on the material lifting grille 6 will fall downward inside the rear side of the top box 7, and the garbage impurities that fall downward will be discharged downward through the sewage discharge cover 10, thereby achieving the purpose of solid-liquid separation and sludge treatment of sewage.

[0023] like Figure 1 、 Figure 2 and Figure 3As shown, a conveyor belt anti-adhesion device 11 is connected to the upper rear end of the center of the left side plate 2 and the right side plate 4. The conveyor belt anti-adhesion device 11 includes a U-shaped fixing frame 13, a metal fixing strip 14, a soft steel wire brush 15 and a fixing bolt 16. The U-shaped opening of the U-shaped fixing frame 13 is arranged forward at the rear end of the left side plate 2 and the right side plate 4. Both ends of the opening of the U-shaped fixing frame 13 are fixedly connected to the left side plate 2 and the right side plate 4 respectively by fixing bolts 16. A metal fixing strip 14 is arranged inside the U-shaped U-shaped fixing frame 13, and a soft steel wire brush 15 is arranged at the front end of the metal fixing strip 14. The conveyor belt anti-adhesion device 11 also includes an adjusting screw hole 18 and an adjusting knob 19. , support screw 20 and fixed bearing 21, an adjusting screw hole 18 is provided inside the center of the rear end of the U-shaped fixing frame 13, and a support screw 20 is threadedly inserted in the adjusting screw hole 18. A fixed bearing 21 is fixed at the center of the outer wall of the rear end of the metal fixing strip 14. The fixed bearing 21 not only connects the support screw 20 and the metal fixing strip 14, but also allows the support screw 20 to rotate independently. Only in this way can the support screw 20 normally drive the metal fixing strip 14 to move back and forth in the U-shaped fixing frame 13. The front end of the support screw 20 is plugged and fixed in the fixed bearing 21. The rear end of the support screw 20 is provided with an adjusting knob 19. The adjusting knob 19 can drive the support screw 20 to rotate clockwise and counterclockwise. When the support screw 20 rotates clockwise and counterclockwise, it can move forward and backward in the adjusting screw hole 18 through the pushing action of the thread. The fixed bearing 21 can fix the front end of the support screw 20 while allowing the support screw 20 to rotate. The conveyor belt anti-adhesion device 11 also includes a stabilizing guide hole 17 and a stabilizing guide rod 22. Stabilizing guide holes 17 are provided on the left and right sides of the center of the rear end of the U-shaped fixing frame 13. Stabilizing guide rods 22 are inserted into the stabilizing guide holes 17. The front end of the stabilizing guide rod 22 is fixedly connected to the outer wall of the rear end of the U-shaped fixing frame 13 by welding. When the support screw 20 is adjusted by rotating the metal fixing bar, the metal fixing bar is rotated. Because the two stabilizing guide rods 22 are respectively inserted into the two stabilizing guide holes 17, the support screw 20 will not drive the metal fixing strip 14 to rotate when rotating, ensuring that the metal fixing strip 14 can move back and forth normally inside the U-shaped fixing frame 13. At the same time, when the soft steel wire brush 15 contacts and rubs against the rear end outer wall of the format conveyor belt, the two stabilizing guide rods 22 inserted in the stabilizing guide holes 17 can help the metal fixing strip 14 resist the impact force, ensuring that the soft steel wire brush 15 can stably contact the rear end outer wall of the format conveyor belt, so that the soft steel wire brush 15 can clean up the garbage and impurities attached to the outer wall of the grille conveyor belt 5.

[0024] like Figure 1 、 Figure 2 and Figure 3As shown, when the conveyor belt anti-adhesion device 11 is used to clean garbage impurities adhered to the grille conveyor belt 5, the conveyor belt anti-adhesion device 11 needs to be adjusted. Specifically, the support screw 20 needs to be rotated by the adjusting knob 19. The support screw 20 and the adjusting screw hole 18 move toward the rear end outer wall of the grille conveyor belt 5 through the threaded pushing action. The support screw 20 will move the metal fixed strip 14 toward the rear end outer wall of the grille conveyor belt 5 until the soft steel wire brush 15 at the rear end of the metal fixed strip 14 fits on the grille conveyor belt 5, and then stop rotating the adjusting knob 19 so that the metal fixed strip 14 and the soft steel wire brush 15 are locked in the current position. When the grille conveyor belt 5 lifts the blocked garbage impurities upward and passes through the sewage cover 10 After being discharged, the grille conveyor belt 5 will rotate downward between the rear ends of the left side plate 2 and the right side plate 4. During the rotation process, the grille conveyor belt 5 is always in contact with the soft steel wire brush 15. The soft steel wire brush 15 will scrape and clean the garbage impurities attached to the outer wall of the grille conveyor belt 5, so that there will not be much garbage impurities attached to the grille conveyor belt 5. When the grille conveyor belt 5 rotates between the left side plate 2 and the bottom front end of the right side plate 4, the sewage will pass through the grille conveyor belt 5. Because there is no garbage impurities attached to the grille conveyor belt 5, it can ensure that the sewage can pass normally, and the garbage impurities in the sewage will be normally blocked by the grille conveyor belt 5, so that the grille conveyor belt 5 can normally lift the blocked and retained garbage impurities upward, and finally separate and discharge the garbage impurities.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
