Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-3, a rare earth wastewater impurity filtering device, comprising a filtering tank 1, characterized in that: a plurality of filter screens 2 are arranged in the filter tank 1 from high to low, an inclined plate 3 for guiding wastewater to enter the lower filter screen 2 is arranged at the bottom of the filter screen 2, and a cleaning mechanism for cleaning the filter screens 2 is arranged above each filter screen 2; the cleaning mechanism comprises a connecting rod 4, a scraping plate 5, a sealing plate 6, a collecting box 7 and a telescopic machine 9, wherein the scraping plate 5 and the sealing plate 6 are arranged at the bottom of the connecting rod 4 and are respectively arranged at two sides of the filter screen 2, the connecting rod 4 penetrates through one side of the filter tank 1 and is connected with the telescopic end of the telescopic machine 9, the connecting rod 4 is in sliding connection with the filter tank 1, the scraping plate 5 is in sliding connection with the filter screen 2, the sealing plate 6 is positioned at a side opening 11 formed in the side wall of the filter tank 1 and can prevent waste water from leaking from the side opening 11, and the collecting box 7 is arranged at the position outside the filter tank 1 and below the side opening 11.
The connecting rod 4 is internally provided with a dust collection pipeline 8, one end of the dust collection pipeline 8 is communicated with an external dust collector, the other end of the dust collection pipeline 8 is communicated with the bottom opening of the scraping plate 5, and impurities remained on the filter screen 2 can be removed when the scraping plate 5 passes through the filter screen 2.
