[0027] Embodiment 1: A drainage filter for building construction and municipal engineering, comprising a filter box 1, the upper and lower surfaces of the filter box 1 are connected to a drainage pipe 2, the inner side walls of the filter box 1 are fixedly connected with slide rails 3, the surfaces of the two slide rails 3 are slidably sleeved with connecting sleeves 4, a filter screen 5 is fixedly connected between the two connecting sleeves 4, a collecting box 6 is fixedly connected to the side of the filter box 1, and an opening is provided on the side where the collecting box 6 is connected to the filter box 1, a threaded rod 7 is rotatably connected between the inner side walls of the filter box 1, a threaded sleeve 8 is threadedly sleeved on the surface of the threaded rod 7, a scraper 9 is fixedly connected to the lower surface of the threaded sleeve 8, a slide groove 10 is provided on the inner side wall of the filter box 1, a slider 11 is slidably sleeved inside the slide groove 10, the slider 11 is fixedly connected to the threaded sleeve 8, and one end of the two slide rails 3 is provided with a quick-release structure 12.

[0028] Embodiment 2: The difference between this embodiment and embodiment 1 is that a driving motor 13 is fixedly connected to the side of the filter box 1, and the output end of the driving motor 13 extends to the interior of the filter box 1 and is fixedly connected to one end of the threaded rod 7. The rotation of the driving motor 13 can drive the scraper 9 to scrape the garbage and impurities on the filter screen 5 into the collection box 6 for collection, thereby avoiding clogging of the filter screen 5.

[0029] Embodiment 3: The difference between this embodiment and embodiment 1 lies in that, the quick-release structure 12 comprises a fixing rod 14, a slot 15, a baffle 16, an insert rod 17 and a spring 18. The fixing rod 14 is fixedly connected to one end of the slide rail 3. There are two groups of slots 15, which are respectively arranged at the same end of the slide rail 3 and the connecting sleeve 4. The baffle 16 is slidably sleeved on the surface of the fixing rod 14. There are two insert rods 17, which are fixedly connected to the surface of the baffle 16. The insert rod 17 matches the slot 15. The spring 18 is fixedly sleeved between the fixing rod 14 and the baffle 16, so as to facilitate and quickly install and disassemble the filter 5 and to replace or clean it.

[0030] Embodiment 4: The difference between this embodiment and embodiment 1 is that, two support blocks 19 are fixedly connected to the inner bottom wall of the collection box 6, a collection basket 20 is placed above the two support blocks 19, and a plurality of water-permeable holes are provided on the surface of the collection basket 20 to facilitate the unified collection and treatment of garbage impurities.

[0031] Embodiment 5: The difference between this embodiment and embodiment 1 is that a water outlet pipe is connected between the lower surface of the collection box 6 and the drainage pipe 2 below, so as to facilitate the discharge of excess water in the garbage.

[0032] Embodiment 6: The difference between this embodiment and embodiment 1 is that the surfaces of the filter box 1 and the collection box 6 are both provided with sealing doors 21, and handles are fixedly connected to the two sealing doors 21 to facilitate opening the collection box 6 and the filter box 1 for use.

[0033] In summary, when the municipal engineering drainage filter for building construction is in use, water flows into the interior of the filter box 1 through the drainage pipe 2, and then the garbage and impurities in the water flow are filtered through the filter screen 5, and the filtered water is discharged through the drainage pipe 1 below. When there are a lot of garbage and impurities accumulated on the filter screen 5, in order to avoid clogging of the filter screen 5, the threaded rod 7 is driven to rotate by controlling the driving motor 13, thereby driving the threaded sleeve 8 and the scraper 9 to move under the restriction of the slide groove 10 and the slider 11, so that the garbage and impurities on the filter screen 5 are scraped to the opening on one side of the filter box 1 and flow into the collection basket 20 inside the collection box 6, and the excess water can flow out through the water permeable holes on the surface of the collection basket 20 and flow into the drainage pipe 1 through the outlet pipe for discharge. When the filter screen 5 needs to be replaced or disassembled for cleaning, the sealing door 21 of the filter box 1 is opened, and then the baffle 16 is pulled outward to disengage the two plug rods 17. When the filter screen 5 is installed, the connecting sleeves 4 on both sides of the filter screen 5 are sleeved on the surface of the slide rail 3, and then the baffle plate 16 is pulled outward to make the two plugging rods 17 disengage from the two slots 15 at one end of the slide rail 3, and then the baffle plate 16 is rotated to make it insert into the slot 15 at one end of the connecting sleeve 4, thereby fixing the connecting sleeve 4 and the filter screen 5. When the filter screen 5 is in use, the garbage in the water flow can be filtered and collected, and the garbage on the filter screen 5 can be automatically cleaned to avoid clogging of the filter screen 5. At the same time, the filter screen 5 can be quickly installed and disassembled, which is convenient for replacing and cleaning.
