Abstract

The utility model relates to an integrated sedimentation and suspension filtering water purifier. Suspended particles are used as filtering materials. Three processes of flocculation, sedimentation, and filtration usually used by water treatment are designed in the same container. A flocculating and air cavity is arranged at the bottom, a sedimentation cavity is arranged on the center, and a filtration cavity is arranged on the upper part. A space is fully used, connecting pipelines and valves among the parts are reduced, an occupation area is reduced, and filtering efficiency is enhanced. The unique backwashing technology that air is used as power is adopted, and sludge and sedimentation sludge in the filtering materials are easily and cleanly cleaned. The suspended particles are used as the filtering materials, and the utility model has very high sludge blocking capacity and sludge holding capacity, long working periods, and less flushing water consumption.

Description

Integrated sedimentation suspends and filters purifier

The present invention for a kind of be filter material with suspended particles, with the purifier that flocculation, sedimentation, filtration combine together, be specially adapted to the purificating raw water of middle-size and small-size water factory, the recovery of the wastewater treatment of industrial and mining enterprises and fine powder class industrial chemicals.

Water technology commonly used now, sedimentation and filtration are two independently monomers, and their turbidity removal process and spoil disposal process all are that independently floor space is big, and connecting pipeline and valve are many, need operation separately.Filtrate adopts sand, material that the coal isodensity is bigger, and filtered water is a mobile from the top down, and water resistance is big, and the soil removability of unit volume is poor, and contamination capacity is little.In case settling bowl delivery turbidity height, the sand filtration effluent characteristics is just poor, is difficult to reach water supply requirement.If former water organism is many or algae is many, filter tank knot mud ball appears easily, influence filter effect.

Purpose of the present invention just is to improve existing water purification technology, and flocculation, sedimentation, filtration are combined together, designs a kind of small-sized efficient purifier.

Purifier of the present invention is by flocculating chamber's air chamber (1) of holding concurrently, negative area (2), suspended particles filtering layer (3), web plate (4), clean water basin (5), water inlet pipe valve (6), blow off valve (7), spoil disposal pipe valve (8), air inlet pipe valve (9), rising pipe (10), sealing pipe valve parts such as (11) are formed.Filtering layer adopts suspended particles as filtrate, and suspended particles generally are light plastic particle or expanded particle, and density is littler than filter liquide, the top of filtering layer is equally distributed grid or filter cap, its effect is water distribution uniformity on the one hand, withstands filtrate on the other hand, does not allow loss.Swash plate or inclined tube are selected in the negative area, and when the negative area was not provided with swash plate or inclined tube, purifier was similar to a strainer.Flocculating chamber's air chamber of holding concurrently, during the purifier operation, it is a flocculating chamber, when purifier cleaned spoil disposal, flocculating chamber's double as air chamber provided the power of current vigorous exercise when cleaning.

Introduce the purifier working process below, during filtration, former water arrives the flocculating chamber from water inlet pipe, flocculation knot alumen ustum, passage flows into swash plate or inclined tube negative area from the bottom along the flocculating chamber and between crust of the device then, rise to the suspended particles filtering layer after precipitating a part of suspended substance, filter through particle layer, clear water flows out from clean water basin top rising pipe (10).During flushing, close water intaking valve (6) earlier, throw air valve (9) into, allow the flocculating chamber be full of air, then, open vent valve (7), the clear water of clean water basin is flowed downward fast, rinse out the mud in filtrate and the negative area, open mud valve at last, discharge sludge water, restart filtration after the emptying.

Purifier of the present invention adopts pressure type to filter and the non-pressure formula is filtered two kinds of mode of operation, and sealing pipe valve (11) is provided with for pressure type filters.When adopting the non-pressure formula to filter, sealed tube (11) leads to atmosphere, does not have valve.When adopting pressure type to filter, output water has certain pressure, and during filtration, seal valve (11) should be closed.When cleaning spoil disposal, seal valve (11) is opened.

This paper and existing water-purifying process relatively have following advantage

1. floor space is little, and pipeline is simple, installs easily.

2. simple in structure, easy to operate.

3. cleaning water height, steady quality.

4. flushing is thorough, and filtrate is difficult for the knot clod, has avoided wearing filter.

The cycle of operation long, the flushing water consumption few.

6. can purify common water purification technology insurmountable toughness fine powder

Sewage.

Accompanying drawing is the structural representation of purifier of the present invention, among the figure

1. flocculating chamber's air chamber 7. blow off valves of holding concurrently

2. negative area 8. spoil disposal pipe valves

3. suspended particles filtering layer 9. air inlet pipe valves

4. web plate 10. rising pipes

5. clean water basin 11. seal pipe valves

6. water inlet pipe valve

Claims

1. bottom-up arrangement, flocculation-sedimentation-filtering integral refining plant, the bottom that it is characterized in that device is flocculating chamber's air chamber (1) of holding concurrently, the centre is negative area (2), the top of negative area is lightweight suspension filter material layer (3), the top of filtrate is grid (4), and grid top is clear water zone (5).

2. according to the said purifier of claim 1, it is characterized by the top filtrate is the lightweight suspension particle, and density is littler than filter liquide, and top is pushed down with uniform grid or filter cap, and the space of grid or filter cap can not run off filtrate less than filtrate from mesh.

3. according to the said purifier of claim 1, it is characterized by the negative area and can adopt inclined tube, swash plate or natural subsidence, when the negative area is not provided with any mechanical part and during natural subsidence, this purifier resembles a suspended particles strainer.
