Fibre filter material filtering basin

Abstract

The invention relates to a fiber filter material filtering pool, comprising a body (1), a water tank (2), a screen plate (3), a filtering layer (4), a porous plate (5), a filtering cap (6), an air distributing hole (7), a water distributing hole (8), a water hole (9), an air water cavity (10), a water cavity (11), a support (12), an air inlet hole (13), a filtering cavity (14), a drainage hole (15), a framework (16) and a drainage groove (17). Compared with the prior art, the upper edge of the inclined surface of the water tank is wave-like, so that the spraying of water is more even; the surface of the screen plate is easy to wash and clean; the packing of the filtering layer are balls with smooth surfaces; no cleaning screen plate is arranged; the fiber strand is not easy to roll or break; the consumption of back washing pressure is low; the outlet of the air distributing hole is lower than the filtering cap, the horizontal position thereof and the filtering cap are staggered; an air hole is opened at the support, so that the air layer is even, thus ensuring the smoothness of the filtering layer and fully taking the advantage of deep filtration of rotary-wing-type fiber filter material. Practice shows that the fiber filter material filtering pool has the advantages of high filter fineness, rapid filtering speed and good back washing effect, and is advanced.

Description

【Technical field】 [0001] The invention relates to a filter tank, in particular to a filter tank with fiber filter material as a filter layer, which belongs to the field of filter equipment. 【Background technique】 [0002] Quartz sand or anthracite is generally used as the filter material of traditional filter tanks. This kind of filter tank has a low filtration rate, low filtration precision and small dirt holding capacity. A fiber filter tank disclosed in Patent Publication No. CN1712096A uses comet fiber filter material, but a filter screen plate is set under the filter layer, and quartz sand is filled in the middle, which increases the resistance of backwashing, and cannot solve the problems of filter material winding around the filter screen plate, broken fibers and backwashing of broken fibers. The screen plate is equipped with dovetail-shaped ribs and dovetail-shaped grooves, and the small filter screen plates can be interlocked to form a large filter plate, but this d...

[0002] Quartz sand or anthracite is generally used as the filter material of traditional filter tanks. This kind of filter tank has a low filtration rate, low filtration precision and small dirt holding capacity. A fiber filter tank disclosed in Patent Publication No. CN1712096A uses comet fiber filter material, but a filter screen plate is set under the filter layer, and quartz sand is filled in the middle, which increases the resistance of backwashing, and cannot solve the problems of filter material winding around the filter screen plate, broken fibers and backwashing of broken fibers. The screen plate is equipped with dovetail-shaped ribs and dovetail-shaped grooves, and the small filter screen plates can be interlocked to form a large filter plate, but this does not solve the problem of adjusting the size of the filter screen plates during construction, so that the fiber filter material cannot be fully utilized The advantages of high precision, large dirt holding capacity and fast filtration speed
