Problems solved by technology
[0004] The technical problem to be solved by the present invention is that during the use of the existing filter felt, the efficiency of the liquid passing through the filter felt is low, and the particle size of the solid matter easily enters the fiber interlayer of the filter felt, causing blockage, and in severe cases, the problem of failure of the filter felt

Abstract
The invention relates to a manufacturing method of high-precision vertical filter felt. The manufacturing method comprises the following steps: S1, opening, mixing and carding fibers to form single-layer webs; S2, performing vertical lapping on the single-layer webs through a vertical lapping machine, namely translating the vertically-falling single-layer webs left and right in the vertical lapping machine to enable the webs to be horizontally laid and stacked in a vertical channel of the vertical lapping machine, and then feeding the stacked webs into a horizontal channel of the vertical lapping machine to convert the horizontally-stacked webs into longitudinally- stacked webs; S3, after vertical lapping, consolidating and molding the longitudinally-stacked webs to obtain vertical filter felt fabric; and S4, outputting the vertical filter felt fabric, and cutting to obtain a vertical filter felt product which is of a vertical filter channel structure in the thickness direction. The method is simple, convenient and reliable; the prepared filter felt is of a vertical structure in the filtering direction, the vertical channel is formed, rapid passing of liquid is facilitated, filtering resistance is effectively reduced, and operation energy consumption is reduced.
Description
technical field [0001] The invention relates to the field of filter material manufacturing, in particular to a method for manufacturing a high-precision upright filter felt. Background technique [0002] At present, chemical fiber filter mats for liquid-solid separation mainly use cross-laying to achieve the required product gram weight (weight per unit area), that is, the gram weight of its single-layer fleece (generally 20-30g / m 2 ), through multi-layer cross-lapping in the thickness direction of the filter felt, to achieve the required product weight. [0003] The disadvantages of the existing structure are: 1. Cross-laying makes the fiber web form a random and disorderly structure in the thickness direction of the filter felt (ie, the filtration direction), which is not conducive to the passage of liquid in the field of solid-liquid separation, and it is easy to make solid particles The diameter enters the fiber interlayer of the filter felt, causing blockage, which inc...
