Description

Technical Field

[0001] The utility model belongs to the technical field of rainwater recycling and reuse, and particularly relates to an impurity filtering device capable of recycling rainwater for reuse. Background Art

[0002] Rainwater recycling and reuse refers to the collection, treatment and storage of rainwater for use in non-drinking water areas such as urban greening, landscape water bodies, industrial cooling, and firefighting water. However, there are too many impurities in rainwater, especially sediment, and it needs to be filtered before it can be used to a higher extent.

[0003] In the prior art, conventional rainwater impurity filtering devices are usually cylindrical in structure. Rainwater enters the internal filter from the collection port at the top for filtration and treatment. However, after long-term use, the collection port is prone to clogging, resulting in a decrease in the efficiency of rainwater collection. At the same time, it is also troublesome to clean or replace the filter inside the device.

[0004] Therefore, an impurity filtering device that can recycle rainwater for reuse is proposed. Through the triple filtration design of the grille plate, the sedimentation tank and the plant fiber filter, various impurities in the rainwater can be effectively removed. At the same time, a cleaning component is provided to uniformly collect and clean the large particles of impurities intercepted by the grille plate. At the same time, the filter component is easy to disassemble and assemble, which can realize the convenient replacement of the filter. Utility Model Content

[0005] In order to overcome the problems that the collection port of the existing rainwater impurity filtering device is easily clogged and the cleaning or replacement of the filter is relatively troublesome.

[0006] The technical solution of the utility model is: an impurity filtering device that can recycle rainwater for reuse, comprising a collecting hopper; the collecting hopper is a funnel structure with openings at the upper and lower ends; a grille plate for preliminary filtration is fixedly connected to the lower side edge of the inner wall of the collecting hopper; a cleaning component is movably provided at the upper end of the collecting hopper; a dustproof shell is fixedly connected to the lower end of the collecting hopper; a sedimentation box is fixedly connected to the lower end of the dustproof shell in a through-type manner; a filter box is fixedly connected to the right end of the sedimentation box; the sedimentation box and the filter box are both rectangular structures with hollow interiors; a liquid extraction component for extracting rainwater is provided at the upper end of the filter box; and a filter component for filtration is movably provided inside the filter box.

[0007] Preferably, the device is fixed with a grid plate on the inner wall of the collection bucket as the first layer of filtering means for rainwater, which intercepts large particles of impurities in the rainwater such as leaves, and uses a scraper driven by a motor to sweep these impurities into the collection box for unified treatment to avoid clogging the rainwater collection path. By providing a sedimentation box as a second layer of filtering means, it helps to settle the suspended solid particles in the rainwater, and then the upper clear liquid of the rainwater in the sedimentation box is pumped out by a water pump and introduced into the filter box. The rainwater will be filtered through the plant fiber filter net and then accumulated in the filter box for subsequent use. At the same time, the design of the filter assembly slidingly arranged inside the filter box facilitates the convenient replacement of the plant fiber filter net, solving the problem that the collection port of the rainwater impurity filter device is easily blocked and the cleaning or replacement of the filter is more troublesome.
