[0002] In water pretreatment, fine grids are usually used as pretreatment devices, especially artificial grids, which are usually used as sewage pretreatment devices for a long time. This kind of artificial grid needs to be cleaned regularly after long-term use. At present, many artificial grids (grid spacing 2mm), such as the Chinese patent with publication number (CN203411355U), discloses a cylindrical coarse and fine grid integrated device, wherein the grid bar spacing of the fine grid net barrel is 1mm to 10mm, and the cross section of the grid bar is trapezoidal. However, this kind of fine grid often catches some hair and entangles some large garbage at the same time. When cleaning the artificial grid, because the long and soft materials such as hair and fibers are too deeply entangled with the grid bars, they cannot be separated from the grid bars smoothly after flushing, causing the water inlet channel to be blocked and water gushing in front of the grid.

[0005] Furthermore, a positioning groove is provided on the upper end surface of the installation frame, a positioning block adapted to the positioning groove is provided on the lower end surface of the horizontal plate, and a threaded hole is provided on the horizontal plate corresponding to the positioning block.

[0006] Furthermore, the grille body includes a straight rod portion located at the front end surface and a bent portion located at the rear end surface, the left and right ends of the straight rod portion are perpendicular to the rear end surface of the mounting frame, and the left and right ends of the bent portion are inclined to the rear end surface of the mounting frame.

[0012] There is an inclination angle between the bent portion of the rear end face and the straight rod portion of the front end face (i.e., the angle a between the bent portion and the rear end face of the mounting frame is 30-45°, which is equivalent to increasing the overall width of the grille body, and the end of the bent portion is located directly behind the adjacent straight rod portion. Therefore, when the long strip impurities contact the grille body, the long strip impurities are blocked at the front end face of the grille body by the thicker grille body and the adjacent straight rod portion, making it difficult for the long strip impurities to flow through the gap between the two adjacent grille bodies, reducing the probability of winding around the grille body, thereby reducing the number of cleaning times of the grille body and improving the single cleaning efficiency of the grille body. On the other hand, when sewage flows to the straight rod, the water flow speed at that place will be reduced due to the obstruction of the bent part, thereby reducing the flow speed of impurities in the water flow, improving the success rate of the grille body in blocking impurities and improving the filtering effect of impurities. Unscrew the bolts on the horizontal plate, then pull the grille body upward to remove it from the fixed groove, and then push the impurities wrapped around the grille body downward, so that the wrapped impurities can be quickly separated from the lower end of the grille body. After cleaning the impurities, reinsert the grille body into the corresponding fixed groove and screw the bolts back into the horizontal plate. The operation is simple and quick to use.

On the other hand, when long strip impurities in the sewage, such as long and soft impurities such as hair and fibers, flow through the grille body 402, since there is an inclination angle between the bent portion 4022 on the rear end surface and the straight rod portion 4021 on the front end surface (that is, the inclination angle a between the bent portion 4022 and the rear end surface of the mounting frame 1 is 30°-45°, which is equivalent to increasing the overall width of the grille body 402, and the end of the bent portion 4022 is located directly behind the adjacent straight rod portion 4021, when the long strip impurities contact the grille body 402, the long strip impurities are blocked at the front end surface of the grille body 402 by the thicker grille body 402 and the adjacent straight rod portion 4021, so that the long strip impurities are not easy to flow between two adjacent grille bodies 402 The gap between the two sides of the screen 402 is small, which reduces the probability of the screen 402 being entangled, thereby reducing the number of cleaning times of the screen 402, increasing the single use time of the screen 402, and improving the use efficiency; on the other hand, when the sewage flows to the straight rod portion 4021, the water flow speed at this location is reduced due to the obstruction of the bent portion 4022, thereby reducing the flow speed of impurities in the water flow, thereby increasing the success rate of the screen 402 in blocking impurities and improving the filtering effect of impurities; of course, after long-term use, the long strips of impurities will accumulate on the screen body 402. At this time, the bolts on the horizontal plate 401 are unscrewed, and then the screen body 402 is pulled up and removed from the fixing groove 3, and then the impurities wrapped around the screen body 402 are pushed down, so that the wrapped impurities can be quickly separated from the lower end of the screen body 402. After the impurities are cleaned, the screen body 402 is reinserted into the corresponding fixing groove 3, and the bolts are screwed into the horizontal plate 401 again. The operation is simple and the use is convenient and quick.
