Abstract
The utility model discloses an automatic back flushing filter device comprising a filter and a PLC (programmable logic controller) 13, wherein the filter is provided with a water inlet on the upper part and is provided with a water outlet on the lower part, and pressure sensors are respectively arranged on the water inlet and the water outlet; when the sensors detect that the differential pressure of gauges at the water inlet and the water outlet of the filter achieves 0.06Mpa, the system automatically conducts the back flushing. According to the automatic back flushing filter device, the original manual operation is altered, the full automatic running of the back flushing and front flushing is realized, and the back flushing is high in accuracy and good in efficiency.
Description
Technical field
The utility model relates to a kind of filter, especially relates to the automatic back-flushing filtering device that a kind of swimming pool is used.
Background technology
Each swimming pool all can the mounting filtering device; Water to swimming pool carries out reusing after a series of filtration; Existing filter plant has mainly contained quartz sand, diatomite, non-woven bag, refill or the like filter; The effect of filter is exactly to utilize filtering medium layer that the big and small impurity in the water is trapped in the filtering medium layer, and water goes out through the micropore laminar flow of filter medium.Dirty when the filter medium layer, that is to say when a lot of impurity has been held back in the inside and just need clean.The observation if non-woven bag, refill filter can open it of existing filter is cleaned it then.But for quartz sand, diatomaceous earth filter; In regular job, can't also need not to open the filter lid goes to observe; According to the difference of filter current stress and filter pressure under the best condition of normal filtration calculate whether needs carry out backwash usually, and backwash all is manually to carry out; Can a large amount of labour of waste, very inconvenience.And just in case the backwashing time choosing is incorrect, the untimely or frequent backwash of backwash also can cause the phenomenon of waste of manpower financial resources.
The utility model content
The utility model is to the deficiency of prior art, and a kind of simple in structure, backwash effect good, efficient is high automatic back-flushing filtering device is provided.
For realizing above-mentioned purpose; The utility model can be taked following technical proposals: a kind of automatic back-flushing filtering device; Comprise filter, PLC controller; The top of said filter is provided with water inlet, and the bottom is provided with delivery port, it is characterized in that: be equipped with pressure sensor on said water inlet, the delivery port; Said water inlet links to each other with blow-off pipe, and the water inlet end of said blow-off pipe is provided with electric filtered water inlet valve, and the water side of blow-off pipe is provided with electric sewage backwash valve; Said delivery port links to each other with feed pipe, and the water inlet end of said feed pipe is provided with electric backwash water intaking valve, and the water side of feed pipe is provided with electricity and filters out water valve; The water inlet end of said blow-off pipe links to each other with the water inlet end of feed pipe; The water side of said blow-off pipe links to each other through blow down branch with the water side of feed pipe, and said blow down branch is provided with electricity and is just washing blowoff valve; Said pressure sensor, electric sewage backwash valve, electric filtered water inlet valve, electricity filter out that water valve, electricity are just washing blowoff valve, electric backwash water intaking valve is electrically connected with the PLC controller respectively.
Accumulation along with the unit normal filtration time; The dirt that the filter bed surface is gathered increases gradually; Filtration resistance increases, and influences filter effect, when the gauge pressure difference that the pressure sensor on being arranged on filter water inlet and delivery port detects the filter entery and delivery port reaches 0.06Mpa; System will carry out backwash automatically: PLC controller control electricity filters out water valve, electric filtered water inlet valve cuts out; After the system of treating shut down 2-3 minute, device restarted electric backwash water intaking valve and electric sewage backwash valve, and backwash begins.Backwash carries out that system controls electric sewage backwash valve after 5-7 minute, electric backwash water intaking valve is closed, and backwash finishes.
After backwash, the part dirt also accumulates on filtering layer and the pipeline, influences swimming pool water quality for making dirt not get into swimming pool; Simultaneously filtrate is put in order; When backwash finishes, should in time just wash, close electric sewage backwash valve, electric backwash water intaking valve earlier, open electric filtered water inlet valve, electricity is just washing blowoff valve; Continue to close electricity after 1-2 minute and just washing blowoff valve, electric filtered water inlet valve, just washing end.Just washing end, system is directly switch to the filtration state.
In sum, the beneficial effect of the utility model is: the utility model has changed original manual operation, has realized backwash, has just washed full-automation and carry out, and the backwash precision is high, excellent in efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
In order to make those skilled in the art person better understand the utility model scheme; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, complete description; Obviously, described embodiment only is a part of embodiment of the utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the utility model protection.
As shown in Figure 1, the utility model comprises filter 1, PLC controller 13, and the top of filter 1 is provided with water inlet, and the bottom is provided with delivery port, and pressure sensor 17 all is housed on water inlet, the delivery port; Water inlet links to each other with blow-off pipe 4, and the water inlet end of blow-off pipe 4 is equipped with electric filtered water inlet valve 5, and electric sewage backwash valve 6 is equipped with in the water side of blow-off pipe 4; Delivery port links to each other with feed pipe 7, and the water inlet end of feed pipe 7 is equipped with electric backwash water intaking valve 8, and the water side of feed pipe 7 is equipped with electricity and is filtered out water valve 9; The water inlet end of blow-off pipe 4 links to each other with the water inlet end of feed pipe 7; The water side of blow-off pipe 4 links to each other through blow down branch 10 with the water side of feed pipe 7, electricity is housed on the blow down branch 10 is just washing blowoff valve 11; Pressure sensor 17, electric sewage backwash valve 6, electric filtered water inlet valve 5, electricity filter out that water valve 9, electricity are just washing blowoff valve 11, electric backwash water intaking valve 8 is electrically connected with PLC controller 13 respectively.The utility model has changed original manual operation, has realized backwash, has just washed full-automation and carry out, and the backwash precision is high, excellent in efficiency.
