Abstract

The utility model relates to a water treatment device, in particular to a rotational flow filter which comprises a barrel body and a top cover arranged on the top of the barrel body. A water outlet and a water inlet are arranged in the top cover, and the water inlet is vertical downwards. A flow choking layer is positioned inside the barrel body, and a biological film layer is filled between the inner wall of the barrel body and the flow choking layer. A channel communicated with the water outlet is installed in the center of the flow choking layer. An L-shaped pipe used for changing the flow direction of fluid is installed in the water inlet of the top cover. The rotational flow filter enables a filter element to better adsorb and intercept organic chemicals, heavy metal and suspended matters in water, turbidity and residual chlorine content of the water can be reduced, production cost of the filter can be lowered, a reverse washing function of the filter can be achieved, and service life of the filter can be prolonged.

Description

A kind of spiral-flow filter
Technical field
The utility model relates to a kind of water treatment device, is specially a kind of spiral-flow filter.
Background technology
Existing product all is to adopt PP cotton core and the split type filtration of gac core following current, as shown in Figure 1, and its existence not enough as follows:
(1) fluid is short through the time of active carbon layer 7 contacts, and organic chemistry material is low by charcoal particle micro-porous adsorption efficient;
(2) PP cotton 8 filters and gac 7 filters because disposing respectively, so its production cost is relatively high;
(3) can only forward flow because of flow direction, can't carry out counterflush (because reverse flow can burst the cotton bag of PP), so the work-ing life of strainer is relatively short.
The utility model content
The purpose of this utility model is, for the deficiencies in the prior art, provides a kind of spiral-flow filter, strengthens filter core to the absorption of organic chemistry material contained in the water, heavy metal and suspended substance and holds back, and adsorption efficiency is high, and production cost is low.
The technical solution of the utility model is, a kind of spiral-flow filter, the top cover that comprises cylindrical shell and cylindrical shell top, top cover is provided with water outlet and water-in straight down, be provided with impermeable barrier in the described cylindrical shell and between impermeable barrier and cylinder inboard wall the filled biomass rete, there is the passage that is communicated with water outlet at the impermeable barrier center; The L shaped pipe that changes direction of flow is installed in the described top cover water-in.
The top of L shaped pipe is provided with separation net in the described water-in.
Described impermeable barrier is the PP cotton core.
Described biological membranous layer is active carbon layer.
Principle of work of the present utility model is: water is under the driving of pressure, flow into from water-in, through the separation net of loam cake inside to elbow, elbow makes current change direction, the formation swirl shape flows, slowly equably down infiltration, contact with the particle of active carbon layer, the organic chemistry material in the water obtains the abundant absorption of carbon granule, and water penetrates the carbon granule layer, a slightly large carbon granule (greater than 5 microns) part is attached to PP cotton core cylindrical outer surface, slightly little part is infiltrated in the PP barred body, forms the damper hole layer, and Powdered carbon granule (less than 5 microns) compiles the cotton center of PP that flows to through the cotton micropore of PP, up flow through the center thrust-augmenting nozzle again, discharge through water outlet.
During normal operation, behind the large granular impurity inflow filter, be deposited in the active carbon layer top, form at leisure one deck microbial film effect, the impurity such as the colloid in the trap water.
When the impermeable barrier of PP cotton was thickeied gradually, flow velocity slowed down, and flow also reduces, and when impermeable barrier reached certain thickness, strainer produced auto-lock function, and filtering function lost efficacy.At this moment, can carry out the counterflush mode by disassembling pipeline, as shown in Figure 3, discharge impurity, recover filtering function.
As known from the above, the utility model can strengthen filter core to the absorption of organic chemistry material contained in the water, heavy metal and suspended substance and hold back turbidity and the contents of residual chlorine of reduction water as a kind of spiral-flow filter; Reduce the production cost of strainer; Realize the counterflush function of strainer, prolong the work-ing life of strainer.

Embodiment
Such as Fig. 2, shown in Figure 4, a kind of spiral-flow filter, the top cover 5 that comprises cylindrical shell 6 and cylindrical shell 6 tops, top cover 5 is provided with water outlet 2 and water-in straight down 1, be provided with impermeable barrier 8 in the described cylindrical shell 6 and between impermeable barrier 8 and cylindrical shell 6 inwalls filled biomass rete 7, there is the passage 9 that is communicated with water outlet 2 at impermeable barrier 8 centers; Described top cover water-in 1 interior installation changes the L shaped pipe 4 of direction of flow.
The top of water-in 1 interior L shaped pipe 4 is provided with separation net 3.
Impermeable barrier 8 is the PP cotton core.
Biological membranous layer 7 is active carbon layer.
