[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 An industrial wastewater filtration sedimentation tank includes a sedimentation tank 1 and a filtration unit placed inside the sedimentation tank 1. The filtration unit includes a first filter element 2 and a second filter element 3. Several partition plates 4 are fixedly connected inside the sedimentation tank 1, and the first filter element 2 is provided on the top of each partition plate 4.

[0023] A cleaning unit 5 is also provided on one side of the sedimentation tank 1. The second filter element 3 is installed inside the sedimentation tank 1 through a fixing structure 6. The cleaning unit 5 works in conjunction with the second filter element 3 to separate and clean the dumped sewage.

[0024] In some embodiments, the interior of the sedimentation tank 1 is formed by a number of partition plates 4 to form multiple multi-stage sedimentation tanks. The multiple multi-stage sedimentation tanks are connected by a first filter element 2, which can gradually slow down the water flow when passing through these areas, so that the impurities in the water settle down under the action of gravity. The first filter element 2 acts as a filter, and the multiple first filter elements 2 are connected by a multi-stage filter screen for filtering small particulate impurities.

[0025] The second filter element 3 can perform preliminary mud-water separation on the dumped sewage, and then, together with the cleaning unit 5, can clean up large impurities in the sewage, which is convenient for subsequent sewage sedimentation.

[0026] Furthermore, the fixing structure 6 includes a pair of support parts 61, which are respectively fixedly connected to the top of the sedimentation tank 1 and one inner wall. The support parts 61 extend outward on both sides to form extension parts 62, and the opposite sides of the extension parts 62 extend inward to form positioning grooves 63. The extension parts 62 are also provided with snap-fit ​​parts 64 on both sides.

[0027] Furthermore, the two ends of the second filter element 3 are fixedly connected with connecting parts 65, the connecting parts 65 are engaged in the positioning groove 63, and the engaging part 64 is engaged with the connecting part 65 through the guide slope.

[0028] In this embodiment, the extension 62 and the support 61 are integrally formed and are both preferably made of materials with deformation capabilities, such as rubber or plastic. Specifically, for example... Figure 4 As shown, the extension 62 and the positioning groove 63 form a U-shaped structure, and the extension 62 is provided with deformation grooves on both sides of the closed side that communicate with the positioning groove 63, which makes it easy to move the latching part 64 to separate it from the connecting part 65.

[0029] In specific operation, the opposite ends of the two snap-fit ​​parts 64 are L-shaped and snap-fit ​​with the connecting part 65 through the guide slope at the bottom, and fix the second filter element 3 in conjunction with the positioning groove 63.

[0030] The second filter element 3 is fitted with the inner wall of the sedimentation tank 1 with a gap, which is intended to filter large impurities in the sewage, such as iron filings, colloids, and material particles. Some small particulate impurities also need to be treated by multiple multi-stage sedimentation tanks and the first filter element 2.

[0031] The sedimented impurities can be removed using a sludge suction device.

[0032] More specifically, the cleaning unit 5 includes a connecting rod 51. A cleaning port is provided on one side of the sedimentation tank 1, and the connecting rod 51 is rotatably connected to the inner side of the cleaning port via a driving component. Several scrapers 52 are evenly distributed around the periphery of the connecting rod 51, and a cleaning component 53 is provided at the free end of the scraper 52.

[0033] In general, the free end of the scraper 52 is provided with a receiving groove 521, and the cleaning member 53 is slidably connected in the receiving groove 521 by a compression spring 522. The cleaning end of the cleaning member 53 abuts against the second filter member 3.

[0034] Finally, stop portions 54 are fixedly connected to both sides of the free end of the scraper 52 by fasteners. The stop portions 54 have an L-shaped structure, and one of their bent ends abuts against the extended portions on both sides of the cleaning member 53.

[0035] It should be added that the cleaning unit 5 also includes a collection box, which is fixedly connected to the outer wall of the sedimentation tank 1 below the cleaning port, and is used to collect the impurities cleaned by the scraper 52.

[0036] Furthermore, the driving component is a motor, which drives the connecting rod 51 to rotate multiple scrapers 52. During the rotation of the scrapers 52, the impurities accumulated on the second filter element 3 are cleaned. During the rotation of the scrapers 52, the cleaning component 53 is also driven to rotate synchronously. The cleaning component 53 is a cleaning brush, which cleans the filter holes of the second filter element 3 through the brush face to achieve the anti-clogging function. The filter unit is a filter screen.

[0037] Furthermore, the cleaning component 53 can slide between the receiving groove 521 under the action of the compression spring 522, so that the cleaning component 53 can better press against the second filter component 3 and prevent the screen holes from clogging.

[0038] Furthermore, the fasteners are locking bolts or screws, which are threaded to the scraper 52.

[0039] Working method: During operation, the connecting part 65 is engaged in the positioning groove 63, and during the engagement process, the two side engaging parts 64 will also engage with the connecting part 65 through the guide slope. Then, both ends of the second filter element 3 are fixed to the support part 61. A pair of support parts 61 are respectively fixed to the top and one side inner wall of the sedimentation tank 1 for preliminary mud-water separation of the dumped sewage.

[0040] Then, the drive unit drives the connecting rod 51 to rotate the scraper 52. During the rotation of the scraper 52, the impurities accumulated on the second filter element 3 are cleaned. During the rotation of the scraper 52, the cleaning element 53 is also driven to rotate synchronously. The cleaning element 53 cleans the filter holes of the second filter element 3 through the brush face. The large impurities after cleaning enter the collection box through the cleaning port. The cleaning element 53 can be replaced by unlocking the fastener and the stop part 54.

[0041] Finally, the pre-separated wastewater is transported one by one through the first filter element 2 to the subsequent multi-stage sedimentation tank to achieve wastewater sedimentation treatment.
