As Fig. 3, flow chart for the interior cyclic program of filter: on the normal basis using, close into liquid medicine valve 21, outlet valve 121, open dosing valve 61, circulating valve 123 and air bleeding valve 14, add activated carbon powder from dosing tank 60, Water Pump using for Filter 20 is by filter liquide suction filter vat 10, the filter liquide that is mixed with powdered activated carbon enters internal recycle pipeline 80 from the liquid outlet 12 of filter vat 10, flow to the entrance of Water Pump using for Filter 20 through internal recycle pipeline 80, enter in filter vat with water pump 20 after filtration again, carry out interior circulation; Through inner loop, active carbon is distributed in behind the surface of filter material, and liquid medicine can become clean, and stops inner loop, and filter liquide filters in filter vat 10, recovers normal operating condition.
After filter liquide filters, the impurity of adsorb organic compound can be distributed in the filter material of filter vat 10, uses after a period of time, and filter material can be stopped up by impurity, need clean filter material.For filter material is cleaned, this Backflushing filter also comprises the backwash water pump 30, the filter 40 for impurity screening that is arranged on filter vat 10 belows and the aqua storage tank 50 that are arranged on frame below.The backwash of filter vat 10 is communicated with the entrance of filter 40 with outlet 13, and the impurity in filter vat 10 enters filter 40 with outlet 13 from backwash.Filter 40 carries out solid filtering to the impurity entering, and the liquid mixing in impurity is leached.
One side of backwash water pump 30 is provided with the air entry being communicated with extraneous air, and opposite side is provided with the air inlet being communicated with the gas outlet of air compressor machine 70.The outlet of backwash water pump 30 is communicated with the liquid outlet 12 of filter vat 10, the outlet of filter 40 is communicated with the entrance of aqua storage tank 50, air compressor machine 70 inflates air in backwash water pump 30, make its startup, the remaining liq that backwash water pump 30 filters out air and filter vat 10 mixes and is pressed in filter vat 10, and the filter material in filter vat 10 is rinsed; The impurity that filter material is gone out after rinsing is through backwash with in outlet 13 inflow filters 40, and filter 40 carries out solid filtering to the impurity entering, and the liquid mixing in impurity is leached; The liquid leaching in filter 40, under the driving of backwash water pump 30, enters in aqua storage tank 50.
The outlet of aqua storage tank 50 is communicated with the entrance of Water Pump using for Filter 20, and the liquid storing in aqua storage tank 50 can flow in Water Pump using for Filter 20, and by carrying out circulating filtration in Water Pump using for Filter 20 suction filter vats 10, reduces the generation of waste water.
Wherein, the liquid outlet 12 of filter vat 10 is communicated with tank, backwash water pump 30, internal recycle pipeline 80 by a four-way pipe.
On connecting pipe in the backwash of filter vat 10 with outlet 13 and the entrance of filter 40, be provided with blowoff valve 131, be provided with inlet valve 32 at the air entry of backwash water pump 30, be provided with intake valve 31 at the air inlet of backwash water pump, on the connecting pipe of the outlet of backwash water pump 30 and the liquid outlet 12 of filter vat 10, be provided with flushing valve 122, on the connecting pipe of the outlet of filter 40 and the entrance of aqua storage tank 50, be provided with water intaking valve 51, on the connecting pipe of the outlet of aqua storage tank 50 and the entrance of Water Pump using for Filter 20, be provided with delivery valve 52.
In the time that filter vat 10 is cleaned, filter vat 10 and Water Pump using for Filter 20 quit work.As Fig. 4, flow chart for the backwashing procedures of filter: will enter liquid medicine valve 21, dosing valve 61, outlet valve 121, circulating valve 123, air bleeding valve 14 and delivery valve 52 and close, open inlet valve 32, intake valve 31, flushing valve 122, blowoff valve 131 and water intaking valve 51, open backwash water pump 30 and air compressor machine 70, backwash water pump 30 is sent air in filter vat 10 to, filter material in filter vat 10 is rinsed, impurity in filter material is gone out to the impurity of going out and mix from backwash and 13 enter filter 40 with exporting for rinsing the liquid of impurity; Filter 40 filters the mixture of the impurity entering and liquid, carries out liquid, solid separation, leaches liquid, and the liquid leaching flows in aqua storage tank 50 under the gas pressure of backwash water pump 30.In the time that backwash completes, close backwash water pump 30, and close intake valve 31, flushing valve 122, blowoff valve 131 and water intaking valve 51.
In backwash process, without cleaning with clear water in addition, using water wisely, and in the process of cleaning at filter do not need the seal cover of filter to open, only need be at the enterprising line operate of machine, can allow the filter material stopping up clean, on cleaning operation, reduce many links, also reduced personnel in operational problem, saved time, manpower.
Liquid in inflow aqua storage tank 50 can flow to again the entrance of Water Pump using for Filter 20, as Fig. 5, flow chart for the flushing liquid circulating filtration program of filter: open delivery valve 52, the liquid storing in aqua storage tank 50 flows into the entrance of Water Pump using for Filter 20 because of vertical parallax.
Opening when Water Pump using for Filter 20, the liquid that flows into Water Pump using for Filter 20 entrances and water storage device 50 is just drawn into and in filter vat 10, carries out interior cyclic program filtration, in process without the generation of waste water.At present environmental protection condition, under the harsh and wastewater treatment expense prerequisite under being in not, without the generation of waste water, beneficial effect is particularly visible.
Wherein, filter 40 is a bag filter formula filter vat 10, and the filter bag in bag filter formula filter vat 10 is after backwash process, and impurity is deposited in filter bag, filter bag is taken out rear directly with air gun hydro-peening in the above, and impurity is sprayed into recycling bin.When normal use, filter bag in bag filter formula filter vat 10 is taken out to cleaning, the method of cleaning is for turning bag filter formula filter bag to collection bag, with air gun jet cleaning, in this operating process, can avoid unnecessary waste water and filter liquide to produce completely, reduce greatly the use at water source, meet present environmental requirement.
The utility model is improved the cleaning process of original filter, utilizing filter vat 10 to filter remaining liquid rinses filter material through 30 punching presses of backwash water pump, without cleaning with clear water in addition, using water wisely, and in the process of cleaning at filter do not need the seal cover of filter to open, only need be at the enterprising line operate of machine, can allow the filter core stopping up clean, many links on cleaning operation, are reduced, also personnel have been reduced in operational problem, can reduce because operating upper possible error, save time, manpower, solve original filter consuming time in cleaning process, consumption is artificial, the problems such as water consumption.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure transformation that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
