Description

Price fixing filter fiber

Technical field:

The utility model relates to a kind of filter medium of mechanical filter equipment, especially a kind of price fixing filter fiber.

Background technology:

The method that mechanical filter sewage disposal is the most frequently used, different according to filter medium, be divided into granular media filtration and fiber filter two class, granule filter material can only realize filtering to solid suspension crown_interception in water body by hole between filter material surface absorption and sand grains, advantage is that filtering velocity degree is high, but can not filter suspension, fiber filter filters majority fibers class filtrate as filter medium, as shown in Figure 3, fiber 1001 is evenly laid for equal densities 1002, filtered water stream 1 enters from top, particle 2 5001 is all in the distribution of fiber 1001, top easily accumulation simultaneously, easy blocking, shortcoming is that filtering velocity is slow, after filter, water 7001 is out few from below, during backwash, as shown in Figure 4, backwashing water 1 enters from below, not easily backwash is clean for particle 2 5001 in fiber 1001, developing result is not high, fiber 1001 is short for service life.

Utility model content:

For the problems referred to above, a kind of upper price fixing filter fiber of dredging lower close successive steps structure and laying is provided, have the advantage of fiber filtering and granule filter material concurrently, due to the structure that filtrate is special, filter bed porosity is made to form up big and down small Graded Density very soon, make that filter filtering velocity is fast, holding filth capacity is large, easily backwash, be particularly suitable for storage pond, holding pond recirculated water solid suspension and filter.

Price fixing filter fiber, comprise asymmetric filter tow, described asymmetric filter tow is successive steps structure close under upper dredging, lay fiber one, fiber two, fiber three, fiber four from top to down, the density one in described fiber one, fiber two, fiber three, each region of fiber four, density two, density three, density four are different, described density four is greater than density three, and described density three is greater than density two, and described density two is greater than density one.

The beneficial effects of the utility model: the filter bed of asymmetrical fibre bundle filtrate composition is under the compaction of current, current are through fiber one, fiber two, fiber three, resistance is produced during fiber four, from top to bottom, the loss of flood peak gradually reduces, water velocity is more and more faster, the compaction of filtrate is just more and more higher, porosity is more and more less, like this along water (flow) direction, automatic formation continuous print Graded Density filtering layer distribution, define the structure of an inverted pyramid, extremely be conducive to effective separation of solid suspension in water, namely the particle of filter bed top desorption is easy to captured in the filter bed of bottom narrow passage and retains, realize the unification of high filtering velocity and high-precision filtration, improve filter holding filth capacity, extend filter cycle, and energy backwash is effectively clear the solid suspension retained.

Accompanying drawing illustrates:

For ease of illustrating, the utility model has following concrete enforcement and accompanying drawing as detailed description.

Fig. 1 is schematic diagram of the present utility model;

Fig. 2 is that the utility model sends out flushing schematic diagram;

In figure: water 7, filter rear water 7001, backwashing water 8, backwashing water 1, asymmetric filter tow 10 after fiber 1, fiber 1001, density 1002, fiber 22, fiber 33, fiber 44, density 1, density 2 201, density 3 301, density 4 401, particle 1, particle 2 5001, filter footprint 6, filtered water stream 1, filter.

Detailed description of the invention:

As shown in figures 1-4, this detailed description of the invention is by the following technical solutions: price fixing filter fiber, comprise asymmetric filter tow 10, described asymmetric filter tow 10 is successive steps structure close under upper dredging, lay fiber 1 from top to down, fiber 22, fiber 33, fiber 44, described fiber 1, fiber 22, fiber 33, the density 1 in each region of fiber 44, density 2 201, density 3 301, density 4 401 is different, described density 4 401 is greater than density 3 301, described density 3 301 is greater than density 2 201, described density 2 201 is greater than density 1, the filter bed of the utility model asymmetrical fibre bundle filtrate composition is under the compaction of current, current are through fiber 1, fiber 22, fiber 33, resistance is produced when fiber 44, from top to bottom, the loss of flood peak gradually reduces, water velocity is more and more faster, the compaction of filtrate is just more and more higher, porosity is more and more less, like this along water (flow) direction, automatic formation continuous print Graded Density filtering layer distribution, define the structure of an inverted pyramid, extremely be conducive to effective separation of solid suspension in water, namely the particle of filter bed top desorption is easy to captured in the filter bed of bottom narrow passage and retains, realize the unification of high filtering velocity and high-precision filtration, improve filter holding filth capacity, extend filter cycle, and energy backwash is effectively clear the solid suspension retained.

During application, former water enters the filter footprint 6 flowed out lower end by top, particle 1 is by fiber 1, fiber 22, fiber 33, after fiber 44 adsorption filtration, after filter, water 7 flows out from lower end, due to fiber 1, fiber 22, fiber 33, the density 1 of fiber 44, density 2 201, density 3 301, density 4 401 progressively increases, fiber 1, fiber 22, fiber 33, the particle 1 of fiber 44 adsorption progressively reduces, the loss of flood peak gradually reduces, water velocity is more and more faster, fiber 1, fiber 22, fiber 33, the compaction of fiber 44 is just more and more higher, porosity is more and more less, like this along water (flow) direction, automatic formation continuous print Graded Density filtering layer distribution, define the structure of an inverted pyramid, extremely be conducive to effective separation of solid particle 1 in water.

During backwash, because the particle 1 of fiber 1, fiber 22, fiber 33, fiber 44 adsorption progressively reduces, particle 1 major part of absorption is in upper end, backwashing water 8 sprays into from bottom, easily the particle 1 of fiber 1, fiber 22, fiber 33, fiber 44 adsorption is rinsed well from below to up, extend the service life of asymmetric filter tow 10.
