The engineering plastics water collector
Technical field
The utility model relates to a kind of water treatment filter, especially relates to a kind of engineering plastics water collector for shallow media filter.
Background technology
Production, domestic water all will be purified after filtration, and water is retained down the fine particle impurity in the water by behind the filter material layer, the turbidity of water is reduced, thereby water is further purified.Organic substance in the water, bacterium, virus etc. are removed in a large number along with the reduction of turbidity, and therefore filtering is to make water for industrial use and domestic water reach health, safe extremely widely used control techniques.
Shallow media filter is the common equipment of purifying water process, when water when top enters filter material layer, partial suspended thing in the water is because mechanical detention and the suction-operated of filtrate, be retained down by the filter material layer surface, overlap each other between the suspension this moment and the effect such as bridge formation, form the filter membrane that one deck adds on the filter material layer surface, in the filtration afterwards, this metafiltration film plays main filtration, and this mode is called " membrane filtration ".At present, water collector in the shallow media filter is made of horizontally disposed water filter plate and some caps that catchments, the cap that catchments evenly is arranged on the water filter plate, and the tank body of shallow media filter respectively arranges a water inlet, inlet at top and bottom usually, because inlet is single, the interior track of stream of tank body becomes shaped form during filtration, flow velocity is inhomogeneous, the dirt that is retained down is " clock " shape and distributes at filtering layer, produce easily channel, be difficult for forming " filter membrane ", filter the initial stage dirt and leak easily, it is inhomogeneous to catchment; During backwash, can not stir filtering layer, filtrate can not effectively be cleaned, and it is not thorough to remove contamination, and the backwash water consumption is large, and weak effect when causing again filtering, and it is short to produce the water cycle.
The utility model content
The applicant is for above-mentioned problem, be studied improvement, a kind of engineering plastics water collector for shallow media filter is provided, evenly collect the water by filter material layer, make water even at a high speed by the filter material layer in the filter with laminar condition, reach the effect of better filtration; When backwash, the filter material layer of turbulent flow flushing shallow media filter improves backwash effect and efficient, reduces required backwash water consumption.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of engineering plastics water collector comprises the draining assembly, and described draining assembly is the cylindrical housing, and described draining assembly upper end is provided with gland, and the lower end is provided with discharge outlet, and described gland is provided with the cap that catchments; Some upper strata arms are the described draining assembly of radial even connection, some lower floor's arms are the described draining assembly of radial even connection, the position of described upper strata arm is higher than described lower floor arm, and described upper strata arm and described lower floor arm shift to install, and several caps that catchment are vertically set on respectively on described upper strata arm and the described lower floor arm; The from inside to outside downward-sloping setting of described upper strata arm, the described lower floor arm setting that is inclined upwardly from inside to outside.
Further:
The outer end of described lower floor arm is provided with the horizontal cap that catchments.
The cap radial misalignments setting of catchmenting on catchment cap and the described lower floor arm on the arm of described upper strata.
The angle of inclination of described upper strata arm is between 4 ° ~ 15 °.
The angle of inclination of described lower floor arm is between 4 ° ~ 15 °.
The angle of inclination of the angle of inclination of described upper strata arm and described lower floor arm is 6 °.
Described draining assembly, gland, the cap that catchments, upper strata arm, lower floor's arm are made by engineering plastics.
Technique effect of the present utility model is:
The disclosed a kind of engineering plastics water collector for shallow media filter of the utility model, the water after the cap that catchments that evenly arranges will filter is collected equably, makes water even at a high speed by the filter material layer in the filter with laminar condition, reaches the effect of better filtration; When backwash, owing to adopt the manifold configuration of two-layer inclination, and the pipe end at lower floor's arm arranges horizontal collecting head, laterally the tangential pressure water of collecting head ejection is so that filtrate rotates rolling at the spherical tank of filter, make between the filtrate and mutually wash by rubbing with the hands, improve backwash effect and efficient, reduce required backwash water consumption.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, the utility model comprises draining assembly 1, and draining assembly 1 is the cylindrical housing, and the upper end of draining assembly 1 is provided with gland 2, and the lower end of draining assembly 1 is provided with discharge outlet 3, and gland 2 is provided with the cap 4 that catchments.Some upper strata arms 5 are radial even connection draining assembly 1, some lower floor's arms 6 are radial even connection draining assembly 1, the position of upper strata arm 5 is higher than lower floor's arm 6, and upper strata arm 5 shifts to install (Fig. 2) with lower floor's arm 6, upper strata arm 5 is downward-sloping setting from inside to outside, lower floor's arm 6 setting that is inclined upwardly from inside to outside.Usually the angle of inclination of upper strata arm 5 is between 4 ° ~ 15 °, and the angle of inclination of lower floor's arm 6 is between 4 ° ~ 15 °, and in the present embodiment, the angle of inclination of the angle of inclination of upper strata arm 5 and lower floor's arm 6 is 6 °.Several caps 4 that catchment are vertically set on respectively on upper strata arm 5 and the lower floor's arm 6, the cap 4 radial misalignments settings of catchmenting on catchment cap 4 and the lower floor's arm 6 on the upper strata arm 5, and the cap 4 that catchments evenly distributes, and the outer end of lower floor's arm 6 is provided with the horizontal cap 4 that catchments.The quantity of upper strata arm 5, lower floor's arm 6 and the cap 4 that catchments can be determined according to actual needs, in the present embodiment, upper strata arm 5 is respectively equipped with 9 with lower floor's arm 6, upper strata arm 5 is provided with the cap 4 that catchments of three vertical direction, and lower floor's arm 6 is provided with catchment cap 4 and horizontal cap 4 that catchments of two vertical direction; Draining assembly 1, gland 2, the cap 4 that catchments, upper strata arm 5, lower floor's arm 6 adopt engineering plastics to make, and low cost of manufacture is quick and easy for installation.
Water collector of the present utility model is installed on the bottom of shallow media filter, when shallow media filter is in filtration condition, the water of filtered passes through water-locator, the spherical tank of complement filter device, to arrive the filter material layer in the filter near the state of advection, when current filtered the bed of material, impurity was trapped within the filter material layer; Water after the cap 4 that catchments of water collector will filter is collected equably, be pooled to draining assembly 1 through upper strata arm 5 and lower floor's arm 6, and discharge from the delivery port of discharge outlet 3 and filter, because advection filters, filter can filter under high flow velocity, and reaches preferably filter effect.
