In the grid filtering device for sewage treatment provided in embodiment 1 of the present utility model, when the grid filtering device is in operation, the strip grid plate 1 is disposed at a gate into which sewage flows, the sewage must pass through the strip grid plate 1 in the next process, the top of the strip grid plate 1 is completely higher than the water level of the sewage, when the sewage passes through the strip grid 11 on the strip grid plate 1, the impurities with large volume in the sewage are blocked by the strip grid 11, the sewage liquid or some impurities with small volume can pass through the strip grid 11 to enter the subsequent sewage treatment step, while the sewage continuously passes through the strip grid plate 1, the anti-blocking device 2 continuously works, the reciprocating device 21 continuously makes the anti-blocking comb 22 move in the vertical direction, the comb teeth 221 of the anti-blocking comb pass through the strip grid 11, the impurities in front of the strip grid 11 (in the direction of the sewage inflow) are pushed by the comb teeth 221, the impurities are moved in the vertical direction, and the impurities are pushed to the bottom or lifted by the comb teeth 221 to the positions of the impurities to be separated from the water level, so that a part of the sewage is directly carried away from the sewage; compared with the anti-blocking device in the prior art, in the embodiment, as the comb teeth 221 can separate impurities in the sewage from a part of the sewage when moving upwards, the solid impurities separated from the sewage can be scraped by the existing automatic scraping plate and other tools, so that the impurity accumulation speed in the sewage in front of the strip-shaped grid plate 1 is slowed down, the frequency of cleaning the impurities accumulated in front of the grid net by workers can be reduced, and the workload of the workers is reduced.

If the shape of the comb teeth 221 is fixed and the moving speed of the reciprocating means 21 is uniform, the speed of bringing the foreign matters out of the sewage surface when moving vertically upward and into the accommodating case 3 when moving vertically downward is uniform in the course of the movement of the comb teeth 221 in the vertical direction, this method can only reduce the work load of the worker by half because the foreign matter accumulation speed in front of the bar-shaped grid plate 1 is one half of that of the normal case, and in order to further reduce the work load of the worker, in this embodiment, the comb teeth 221 can be narrowed when moving vertically downward by the reciprocating means 21, and the comb teeth 221 do not abut against both side inner walls of the bar-shaped mesh 11 in the vertical direction after being narrowed; the comb teeth 221 are widened to be just abutted against both side inner walls of the strip-shaped mesh 11 when vertically moved up by the reciprocating means 21. When the comb teeth 221 move vertically upwards, all impurities in the strip-shaped mesh openings 11 are moved and brought out of the sewage water surface, and when the comb teeth 221 move vertically downwards, as the comb teeth 221 are narrowed, part of impurities in the strip-shaped mesh openings 11 can only be taken away, the impurities in the sewage are moved downwards and enter the accommodating box 3, so that more impurities are taken away from the sewage in the sewage, the impurities entering the accommodating box are reduced, the frequency of the accommodating box 3 needing to be cleaned is reduced, and the workload of staff is reduced.
In order to realize that the comb teeth 221 are just tightly attached to the inner walls of the two sides of the strip-shaped mesh 11 when moving upwards, the comb teeth 221 can contact accumulated impurities in the strip-shaped mesh 11 and in front of the strip-shaped mesh 11 with smaller cross sections when moving downwards, and as a preferred scheme, in the embodiment, the comb teeth 221 are of a hinge structure; when the comb teeth 221 are vertically moved up by the reciprocating means 21, the hinge structure of the comb teeth 221 is in an open state; when the comb teeth 221 are moved down by the reciprocating means 21, the hinge structures of the comb teeth 221 are in a combined state.
