In order to further adjust the distance between two adjacent teeth 22, the size of the filter cell formed between the teeth 22 and the slider 32 is adjusted, the length of the lower bottom edge of the slider 32 is smaller than the distance between two adjacent teeth, more specifically, the length of the lower bottom edge of the slider 32 is smaller than or equal to half of the distance between two adjacent teeth 22, the slider 32 can slide left and right conveniently, dirt deposited on the slider 32 is scraped off, the slider 32 is prevented from sliding excessively, the filter cell is completely closed, the filter function is lost, and the length of the lower bottom edge of the slider 32 is smaller than the distance between two adjacent teeth. In the prior art, in order to prevent the grid net from being blocked, a water flushing device is arranged, the water consumption is increased, the sliding block 32 is in an inverted trapezoid shape when in use, the rake teeth grid 2 is used for collecting garbage, the sliding block 32 is driven to rotate reversely, filtered water flows are close to the narrower upper bottom surface of the sliding block 32, the water flows are blocked when passing through two adjacent sliding blocks, the impact force and flowing water flow of the water flows are favorable for completing self-cleaning of the rake teeth grid 2, and accumulated sludge or other attachments on the sliding block 32 and the rake teeth 22 are reduced, so that the sewage treatment cost is reduced.
Example 2: in order to realize automatic cleaning of the rake teeth grating 2 and save the device, on the basis of the embodiment 1, as shown in fig. 9 to 10, S-shaped limiting blocks 121 are arranged in the second sliding groove 12 in the mounting frame 1, two ends of the connecting rod 31 are abutted with the inner bottom surface of the second sliding groove 12, and the limiting blocks 121 enable the movable bar 3 to slide left and right along two sides of the rake teeth 22.
Further, as shown in fig. 2 to 3, in order to reduce dirt from entering the mounting frame 1, both ends of the mounting bars 21 of the rake grating 2 are provided with a baffle plate 23 connecting adjacent two of the mounting bars 21. The link 31 is slidably connected to the mounting frame 1 through the shutter 23. In order to optimize the left-right sliding stability of the moving bar 3, the diameter of the mounting rod 21 is larger than that of the link 31. Chains 24 for driving the mounting rods 21 to slide along the first sliding grooves 11 are arranged on two sides of the rake teeth grating 2, and the chains 24 are arranged inside the mounting frame 1.
When the sewage continuous filtering device is used, the installation frame 1 and the harrow tooth grating 2 are installed, the external driving motor drives the harrow tooth grating 2 and the movable bar 3 to slide/rotate along the installation frame 1, and the harrow teeth 22 and the movable bar 3 are matched to form a filtering grid for continuously filtering flowing sewage. During filtering, the size of the filter grid is reduced by adjusting the movable bar block 3, so that the filter grid is suitable for filtering garbage with smaller size, but the filter grid is not blocked by the influence of mud and the like in water flow and loses the filtering function, and the filter grid is specifically as follows: when the wider lower bottom surface of the slide block 32 approaches the filter grid to reduce the size of the filter grid and the dirt accumulated on the lower bottom surface of the slide block 32 increases, the slide block 32 is manually adjusted to slide left and right along the rake teeth 22, and the accumulated sludge or garbage attached to the lower bottom surface of the slide block 32 is removed by utilizing the shearing force between the rake teeth 22 and the slide block 32, so that the sludge between the rake teeth 22 falls off under the action of self gravity due to the loss of the support of the slide block 32, thereby recovering the filtering function of the rake teeth 22. Or an S-shaped limiting block 121 is arranged in the second chute 12 in the mounting frame 1, two ends of the connecting rod 31 are in contact with the bottom surface in the second chute 12, when the connecting rod 31 slides along the second chute 12, the connecting rod passes through the limiting block 121 and can slide left and right along the rake teeth 22 under the driving of the limiting block 121, and the shearing force between the rake teeth 22 and the sliding block 32 enables sludge accumulated on the sliding block 32 to be removed. After the garbage is filtered and collected, the sliding block 32 is driven to rotate reversely, water flow after filtering is close to the narrower upper bottom surface of the sliding block 32, the water flow is blocked when passing through two adjacent sliding blocks, the impact force of the water flow and the flowing water flow are favorable for completing self-cleaning of the filter grid, and the sewage treatment cost is reduced.
