Abstract
The utility model relates to a kind of active sand filter, comprise housing, dirty sand discharge pipe is installed on described enclosure interior center, air lift is connected in one end of described dirty sand discharge pipe, also be communicated with sand-washing device and suction water outlet pipe respectively at the other end of described dirty sand discharge pipe, described sand-washing device is by controlling organization drived control; In the periphery of described dirty sand discharge pipe, also install water-locator in the inside of described housing, described water-locator is communicated with one end of former water water inlet pipe, is also communicated with filtrate discharge mouth on the top of described housing.The utility model structure is simple, easy to use, and they can 24 continuous throughout the twenty-four hour24s, does not need to shut down backwash; the utility model operating cost is low; it does not need high-lift large discharge backwash pump, can adopt the discontinuity Controlling operation methods such as TIS, LIS, reduce application fee.The utility model is low without any rotatable parts, failure rate is low, maintenance cost in running.
Description
Technical field
The utility model relates to filter plant, particularly relates to active sand filter.
Background technology
At present, active sand filter is a kind of Collecting flocculation, clarifies, is filtered into the continuous filtration equipment of one, and effectively can remove the sulphur in water and phosphorus, then existing filtration device structure is single, is difficult to meet actual use needs.
Utility model content
The applicant, for above-mentioned existing issue, is studied improvement, provides active sand filter, and it has compact structure, maintenance, upkeep cost is cheap, kinetic equation loss is little, and does not need ad hoc water for cleaning.
The technical scheme that the utility model adopts is as follows:
A kind of active sand filter, comprise housing, dirty sand discharge pipe is installed on described enclosure interior center, air lift is connected in one end of described dirty sand discharge pipe, also be communicated with sand-washing device and flushing water outlet respectively at the other end of described dirty sand discharge pipe, described sand-washing device is by controlling organization drived control; In the periphery of described dirty sand discharge pipe, also install water-locator in the inside of described housing, described water-locator is communicated with one end of former water water inlet pipe, is also communicated with filtrate discharge mouth on the top of described housing.
Further improvement as technique scheme:
Described sand-washing device is made up of many curved tubes, and described curved tube is along the circumferential direction surrounded on the periphery of dirty sand discharge pipe.
The beneficial effects of the utility model are as follows:
The utility model structure is simple, easy to use, and they can 24 continuous throughout the twenty-four hour24s, does not need to shut down backwash; the utility model operating cost is low; it does not need high-lift large discharge backwash pump, can adopt the discontinuity Controlling operation methods such as TIS, LIS, reduce application fee.The utility model is low without any rotatable parts, failure rate is low, maintenance cost in running, it does not need the facility such as flocculation basin, depositing reservoir, and filter utilization rate is high, and one-time investment is low, click filtrate and filtrate is clean in time owing to adopting, the loss of flood peak can be reduced to 0.5m.Filtrate is in time clean, ensures the filter effect stablized, make laughs, effluent quality aperiodicity is stirred.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, water-locator; 2, filtrate discharge mouth; 3, dirty sand; 4, air lift; 5, sand-washing device; 6, curved tube; 7, flushing water outlet; 8, filtrate; 9, controlling organization; 10, housing; 11, dirty sand discharge pipe; 12, former water water inlet pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1, the active sand filter of the present embodiment, comprise housing 10, dirty sand discharge pipe 11 is installed on housing 10 inside center place, air lift 4 is connected in one end of dirty sand discharge pipe 11, also be communicated with sand-washing device 5 and flushing water outlet 7 respectively at the other end of dirty sand discharge pipe 11, sand-washing device 5 is by controlling organization 9 drived control; In the periphery of dirty sand discharge pipe 11, also install water-locator 1 in the inside of housing 10, water-locator 1 is communicated with one end of former water water inlet pipe 12, is also communicated with filtrate discharge mouth 2 on the top of housing 10.Sand-washing device 5 is made up of many curved tubes 6, and curved tube 6 is along the circumferential direction surrounded on the periphery of dirty sand discharge pipe 11.
Specific works process of the present utility model is as follows:
As shown in Figure 1, former water enters in housing 10 from former water water inlet pipe 12, by water-locator 1, former water is uniformly distributed in housing 10, as shown by the arrows in Figure 1, former water sail against the current by the layer of sand in housing 10 carry out filtration formed filtrate, filtrate is discharged by filtrate discharge mouth 2, sink to the filtrate retaining pollutant bottom housing 10 is upwards drained into housing 10 in dirty sand discharge pipe 11 top by air lift 4, now controlling organization 9 controls sand-washing device 5 and starts, sand-washing device cleans the above-mentioned filtrate retaining pollutant, contaminant water is directly discharged by flushing water outlet 7, clean water then continues to be discharged by filtrate discharge mouth 2, the rinse water used when cleaning the filtrate with trapped substance directly takes from the filter liquor of housing 10 inside, do not need ad hoc water for cleaning,
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range is see claim, and when without prejudice to basic structure of the present utility model, the utility model can do any type of amendment.
