DETAILED DESCRIPTION

[0021] 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 of the embodiments.

The upper end surface of the bottom plate 1 is located on both sides below the two fixing rings 5 ​​and fixed with support wheels 3. The support wheels 3 are rollingly engaged with the groove wheels 13 on the fixing rings 5.

[0024] The rotary drive mechanism includes a gear ring 7 fixed to one end of the outer wall of the grille cylinder 6, a servo motor 2 is fixed to the upper end surface of the bottom plate 1, the output end of the servo motor 2 is connected to a reducer 15 fixed to the upper end surface of the bottom plate 1, one end of the reducer 15 is connected to a driving gear 14, and the driving gear 14 is meshed with the gear ring 7;

[0025] The water filtering mechanism includes a support plate 11 connected to one end of the bottom plate 1, a semicircular water filtering pipe 8 is fixed to one side of the support plate 11, the semicircular water filtering pipe 8 extends to the inside of the grille cylinder 6, and a water filtering net 9 is provided at the part of the semicircular water filtering pipe 8 located inside the grille cylinder 6, and a water inlet pipe 10 is connected to one end of the semicircular water filtering pipe 8 located outside the grille cylinder 6, and the water inlet pipe 10 passes through the support plate 11;

[0026] An overflow weir 16 is provided on one side of the top of the semicircular filter pipe 8 located inside the grille cylinder 6, and the cross section of the grille bars of the grille cylinder 6 is V-shaped;

[0027] The radius of the water inlet 12 is larger than the radius of the semicircular water filter pipe 8. A plug hole is provided on the upper end surface of the bottom plate 1, and the support plate 11 is plugged into the plug hole, which makes it easy to pull out the support plate 11 and take out the semicircular water filter pipe 8 for cleaning, which is convenient and quick.

[0028] Working principle: Suspended matter enters the semicircular filter pipe 8 along the water inlet pipe 10, and is filtered by the filter water net 9. Large solid particles remain in the semicircular filter pipe 8, and wastewater and small solid particles fall into the grid cylinder 6. When the flow rate of the suspended matter is too fast, the wastewater can be discharged from the overflow weir 16 and fall into the grid cylinder 6. The servo motor 2 drives the reducer 15 to rotate, so that the reducer 15 drives the driving gear 14 and the gear ring 7 to rotate, thereby driving the grid cylinder 6 to rotate. Under the rotation shear force of the grid cylinder 6 and the driving action of the arc-shaped guide strip 4, the solid particles are discharged from the grid cylinder 6. The wastewater is discharged from the end of the grille cylinder 6, and is discharged directly through the grille cylinder 6, realizing solid-liquid separation. The grille cylinder 6 adopts a heavy-load design, and the solid grille frame reduces the stress concentration of the V-section wedge-shaped grille bars, which is more suitable for high-concentration wastewater operation. The V-section wedge-shaped grille bars are specially treated to enhance the hardness of the V-shaped grille bars. At the same time, the grafting of the grille adopts Zhouyuan's overall automatic typesetting technology, and performs CNC automatic high-frequency grafting technology to ensure the uniformity of the grille seam. The grille has the advantages of high mechanical strength, not easy to deform, not easy to break, and long service life.
