Description
Technical field
The utility model relates to water filtering device, particularly a kind of unsteady orifice plate fabric filter.
Background technology
The water dispensing apparatus of existing a kind of fabric filter is stacked big flood cap, and stacked big flood cap places the fixedly center of orifice plate top, and what cleaning device adopted is annular antipriming pipe structure.Its weak point is, when filtering, because of stacked big flood cap places the fixedly center of orifice plate top, water is from the water outlet of stacked big flood cap, current come together in the fiberfill middle and upper part, and forming " dead band " relatively around the fiberfill top, this part fiberfill filtering layer is not fully utilized, low, the weak effect of filtering accuracy; When cleaning, moisture becomes two-way, and one the road from the water outlet of stacked big flood cap, and another road needs two valves to control respectively from annular antipriming pipe water outlet, is difficult to even, reasonable distribution two path water flow, influences the backwash effect.Existing a kind of fabric filter complex structure, the manufacturing cost height.
Summary of the invention
The purpose of this utility model is that prior art is improved, and provides a kind of simple in structure, low cost of manufacture, filter, the backwash water assignment of traffic evenly, rationally, filtering accuracy height, effective unsteady orifice plate fabric filter.
The purpose of this utility model is realized by following technical scheme: a kind of unsteady orifice plate fabric filter, it comprises housing, upper end in housing is provided with fixedly orifice plate, the upper end of fiberfill is connected with fixing orifice plate, the lower end of fiberfill is connected with removable orifice plate, be provided with former water inlet, filter back water out, the backwash water inlet, the backwash water outlet, its special character is: in housing, and being positioned at fixedly, the top of orifice plate is provided with the porous water dispensing apparatus, the porous water dispensing apparatus by pipeline respectively with filter back water out, the backwash water inlet connects, top at housing is provided with air outlet slit, in housing, and the below that is positioned at removable orifice plate is provided with the porous air distributing device, the porous air distributing device communicates with air intake, be provided with the mouth of a river in the housing lower end, outlet is connected with backwash water with former water inlet respectively at the described mouth of a river.Said porous water dispensing apparatus is connected with the wash water outlet by pipeline.
Unsteady orifice plate fabric filter of the present utility model is because in housing and be positioned at the porous water dispensing apparatus that is provided with above the fixing orifice plate and enter the mouth and be connected with filter back water out, backwash water respectively by pipeline; The mouth of a river of housing lower end is connected with the outlet of former water inlet and backwash water respectively by pipeline, filter, the backwash water assignment of traffic evenly, reasonable, filtering accuracy height, effective.Have advantages such as simple in structure, low cost of manufacture.
Description of drawings
Fig. 1 is the orifice plate fabric filter structural representation that floats.
Fig. 2 is the orifice plate fabric filter structure cross-sectional schematic of floating.
Among the figure: 1 porous water dispensing apparatus, 2 is orifice plate, 3 fiberfill, 4 removable orifice plate, 5 porous air distributing devices, 6 housings, 7 former water inlets, 8 filter back water outs, 9 backwash water inlet, the outlet of 10 backwash water, the outlet of 11 the wash waters, 12 air intakes, 13 air outlet slits, 14 mouths of a river fixedly.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to Fig. 1 and 2, the orifice plate fabric filter that floats has housing 6, upper end in housing 6 is provided with fixedly orifice plate 2, the upper end of fiberfill 3 is connected with fixing orifice plate 2, the lower end of fiberfill 3 is connected with removable orifice plate 4, in housing 6 and be positioned at fixing orifice plate 2 above be provided with porous water dispensing apparatus 1, porous water dispensing apparatus 1 is connected with filter back water out 8, backwash water inlet 9 and the wash water outlet 11 respectively by same pipeline.Be provided with air outlet slit 13 at the top of housing 6, in housing 6 and be positioned at removable orifice plate 4 below be provided with porous air distributing device 5, porous air distributing device 5 communicates with air intake 12.Be provided with the mouth of a river 14 in housing 6 lower ends, the described mouth of a river 14 is connected with backwash water outlet 10 with former water inlet 7 respectively by same pipeline.
Floating needs just to wash earlier when the orifice plate fabric filter brings into operation: earlier water is entered filter from former water inlet 7 when just washing, and conpressed fibers filler 3, water exports 11 outflow filters through porous water dispensing apparatus 1 and connecting line from the wash water.After just the washing of time of short duration, close the wash water outlet 11.Then, enter the water filtration process.
The filter process of unsteady orifice plate fabric filter is: the water that needs to filter enters filter from former water inlet 7, under the effect of water inlet water flow pressure, removable orifice plate 4 moves along water (flow) direction, some fibre bundles of fiberfill 3 produce crooked, fiberfill 3 is compressed, the fibre bundle of fiberfill 3 is less near removable orifice plate 4 bulk densities, and near fixedly orifice plate 2 bulk densities are bigger, fiberfill 3 can realize the depth-type filtration to impurity in the water, suspension in the water is adsorbed, be trapped in the fiberfill 3, the water after the filtration is through porous water dispensing apparatus 1 and connecting line water out 8 outflow filters after filter.When having held back more suspension in the fiberfill 3 or filter having been cleaned according to field control parameter needs, former water inlet 7 is closed, stop into water.
The cleaning process of unsteady orifice plate fabric filter is: water enters the mouth 9 through connecting line from backwash water, porous water dispensing apparatus 1 is from top to bottom by fiberfill 3, make compressed air from air intake 12 then, porous air distributing device 5 enters fiberfill 3 from the bottom to top, carry out water, the combined cleaning of air, under the impact of current, some fibre bundles of fiberfill 3 are straightened, the hole of fiberfill 3 increases, under compressed-air actuated impact, some fibre bundles are shaken, simultaneously, air bubble flow through around produce high-speed eddy, the suspension that is trapped on some fibre bundles is peeled off, the waste water that cleans exports 10 discharge filters from backwash water, and the waste gas of cleaning is from air outlet slit 13 discharge filters.After cleaning is qualified, close backwash water inlet 9, backwash water outlet 10, air intake 12, air outlet slit 13.
