This Backflushing filter also comprises dosing tank 60 and internal recycle pipeline 80, and dosing tank 60 is communicated with by the entrance of connecting pipe with Water Pump using for Filter 20, and dosing tank 60 with the connecting pipe of the entrance of Water Pump using for Filter 20 are provided with dosing valve 61.One end of internal recycle pipeline 80 is communicated with the liquid outlet 12 of filter vat 10, and the other end of internal recycle pipeline 80 is communicated with the entrance of Water Pump using for Filter 20, and internal recycle pipeline 80 is provided with circulating valve 123.
As Fig. 3, flow chart for the Inner eycle program of filter: on the normal basis used, close into liquid medicine valve 21, outlet valve 121, open dosing valve 61, circulating valve 123 and air bleeding valve 14, activated carbon powder is added from dosing tank 60, Water Pump using for Filter 20 is by filter liquide suction filter vat 10, the filter liquide being mixed with powdered activated carbon enters internal recycle pipeline 80 from the liquid outlet 12 of filter vat 10, the entrance of Water Pump using for Filter 20 is flow to through internal recycle pipeline 80, enter in filter vat with water pump 20 after filtration again, carry out Inner eycle; Through inner loop, after active carbon is distributed in the surface of filter material, liquid medicine can become clean, and stop inner loop, 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, and after using a period of time, filter material can be blocked by impurity, need clean filter material.For cleaning filter material, this Backflushing filter also comprises and is arranged on backwash water pump 30 below frame, is arranged on the filter 40 for impurity screening below filter vat 10 and an aqua storage tank 50.The backwash of filter vat 10 is communicated with the entrance of outlet 13 with filter 40, and the impurity in filter vat 10 enters filter 40 from backwash outlet 13.Filter 40 carries out solid filtering to the impurity entered, and the liquid mixed is leached in impurity.
The side of backwash water pump 30 is provided with the air entry be communicated with extraneous air, and opposite side is provided with the air inlet be 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 it start, in the remaining liq mixing press-in filter vat 10 that air and filter vat 10 filter out by backwash water pump 30, the filter material in filter vat 10 is rinsed; The impurity that filter material is gone out after rinsing is in backwash outlet 13 inflow filter 40, and filter 40 carries out solid filtering to the impurity entered, and the liquid mixed is leached in impurity; The liquid leached 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 stored 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 vat 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.
The backwash outlet 13 of filter vat 10 with the connecting pipe of the entrance of filter 40 are provided with blowoff valve 131, inlet valve 32 is provided with at the air entry of backwash water pump 30, intake valve 31 is provided with at the air inlet of backwash water pump, the connecting pipe of the outlet of backwash water pump 30 and the liquid outlet 12 of filter vat 10 is provided with flushing valve 122, the connecting pipe of the outlet of filter 40 and the entrance of aqua storage tank 50 is provided with water intaking valve 51, the connecting pipe of the outlet of aqua storage tank 50 and the entrance of Water Pump using for Filter 20 is provided with delivery valve 52.
When cleaning filter vat 10, filter vat 10 and Water Pump using for Filter 20 quit work.As Fig. 4, flow chart for the backwashing procedures of filter: liquid medicine valve 21, dosing valve 61, outlet valve 121, circulating valve 123, air bleeding valve 14 and delivery valve 52 will be entered 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, air is sent in filter vat 10 by backwash water pump 30, filter material in filter vat 10 is rinsed, gone out by impurity in filter material, the impurity gone out and the liquid mixing for rinsing impurity enter filter 40 from backwash outlet 13; The mixture of filter 40 to the impurity entered and liquid filters, and carry out liquid, solid is separated, leach liquid, the liquid leached flows in aqua storage tank 50 under the gas pressure of backwash water pump 30.When 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, clean without the need to other clear water, using water wisely, and do not need the seal cover of filter to open in the process of filter cleaning, only at the enterprising line operate of machine, the filter material of blocking need can be allowed to clean, cleaning operation decreases many links, also reduce personnel's problem operationally, save time, manpower.
The liquid flowed in 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 stored in aqua storage tank 50 is because of the entrance of vertical parallax inflow Water Pump using for Filter 20.
When opening Water Pump using for Filter 20, the liquid flowing into Water Pump using for Filter 20 entrance and water storage device 50 is just drawn in filter vat 10 and carries out Inner eycle program filters, without the generation of waste water in process.Under the prerequisite that harsh and wastewater treatment expense is in not at present environmental protection condition, without the generation of waste water, beneficial effect is particularly visible.
Wherein, filter 40 is bag filter formula filter vat 10, and the filter bag in bag filter formula filter vat 10 is after backwash process, and impurity buildups, in filter bag, is taken out rear direct air gun at hydro-peening above filter bag, impurity is sprayed into recycling bin.During normal use, filter bag in bag filter formula filter vat 10 is taken out cleaning, the method of cleaning is for turning bag filter formula filter bag to collection bag, with air gun jet cleaning, unnecessary waste water and filter liquide can be avoided in this operating process completely to produce, reduce the use at water source greatly, meet present environmental requirement.
The cleaning process of the present invention to original filter is improved, utilize filter vat 10 to filter remaining liquid to rinse filter material through backwash water pump 30 punching press, clean without the need to other clear water, using water wisely, and do not need the seal cover of filter to open in the process of filter cleaning, only need at the enterprising line operate of machine, the filter core of blocking can be allowed to clean, cleaning operation decreases many links, also reduce personnel's problem operationally, 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 the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure transformation utilizing description of the present invention 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 invention.
