Improved swimming pool hair filter

Abstract

An improved swimming pool hair filter which has good filtering effect and is easy to operate is disclosed, the improved swimming pool hair filter includes a cylinder and a flange cover, the flange cover is arranged above the cylinder, the cylinder is provided with a gas discharge pipe, a water inlet pipe, a water outlet pipe and a sewage discharge pipe, the water inlet pipe and the water outlet pipe are arranged opposite to each other, the water outlet pipe is higher than the water inlet pipe, two pairs of drawing-inserting grooves which are arranged in parallel are arranged in the cylinder, and are respectively used fixing coarse and fine filter plates, the coarse filter plate is provided with a plurality of filter holes I, middle parts of the filter holes I are in the shape of circular arc projections, the filter holes I are provided with a plurality of barbs, the tips of the barbs face toward the water inlet pipe, the fine filter plate is provided with a plurality of filter holes II, the filter holes II are S-shaped, one side of the fine filter plate, facing toward the coarse filter plate, is provided with a plurality of barrier projections, and the barrier projections are triangular. The improved swimming pool hair filter can cushion water pressure, and enhances filtering effect.

Description

technical field [0001] The invention relates to a device for filtering impurities in water, in particular to a swimming pool hair filter. Background technique [0002] Swimming pools often leave a lot of human hair in the water quality during use. After a long time, the hair may cause the water outlet to block. At present, a hair filter is usually added at the water outlet to intercept the hair and prevent the water outlet from being blocked. In the prior art, a coarse filter and a fine filter are usually arranged in the hair filter, and the hair is filtered through two layers of filtration. But in actual use, because the coarse filter is flat and smooth, even if it can filter part of the hair, when the swimming pool is drained, the strong impact will wash the hair on the coarse filter to the fine filter, resulting in the coarse filter and the fine filter. The water flow between the fine filters is unbalanced, which affects the water discharge efficiency; at the same time,...

Problems solved by technology

But in actual use, because the coarse filter is flat and smooth, even if it can filter part of the hair, when the swimming pool is drained, the strong impact will wash the hair on the coarse filter to the fine filter, resulting in the coarse filter and the fine filter. The water flow between the fine filters is unbalanced, which affects the water discharge efficiency; at the same time, because the impact on the fine filters is much greater than that of the coarse filters, the fine filters are easily damaged, which increases operating costs and easily causes hair to leak into the outlet pipe , causing blockage
