Abstract
The present invention discloses a filtering net filter. A water inlet of the present invention is connected with a water flow separating and switching device. The device is connected with two (more) water inlet chambers, and two (more) water inlet chambers are provided with respective drain openings. Drain valves are both arranged on the drain openings, and the water inlet chambers are both provided with filtering nets. A water outlet chamber is formed between the filtering nets, and the water outlet chamber is provided with a water outlet. The filtering net filter with the structure simultaneously carries out filtration and flushing in one filter and has dual-purpose functions. Flushing water penetrates through the clogging filtering nets from one side of the water outlet chamber to enter one side of each water inlet chamber and is discharged from the drain openings, namely that a flushing water source reversely flushes clogging objects on the filtering nets. The present invention has the advantages of short time and cleanness.
Description
The invention belongs to cleaning equipment, be specifically related to a kind of filter.
At present, the filter of general usefulness is both at home and abroad: one deck filter screen is separated into filter body into and out of hydroecium.Flow direction schematic diagram when Fig. 1,3,5 and 6,9 and 10,13,15 works for filter, flow direction schematic diagram when Fig. 2,4,7 and 8,11 and 12,14,16 washes for filter, shown in Fig. 1,3,5 and 6,9 and 10, after current to be filtered enter intake chamber from water inlet, pass filter screen, to water-supplying chamber, discharge by delivery port.
Shown in Figure 13,15, Figure 13 is that double-layer leaching net is isolated into intake chamber and water-supplying chamber from outer wall to the center with filter body, and current to be filtered enter intake chamber from water inlet, and current pass the ground floor filter screen and enter second intake chamber, then pass second layer filter screen and enter water-supplying chamber, discharge from delivery port.These kind of characteristics are: two intake chambers link, and water-supplying chamber is in a side.Figure 15 is equipped with the drainage box in the water inlet, current enter intake chamber after filtering for the first time by the drainage box, are discharged through delivery port by water-supplying chamber by filter screen again.
When the filter of above-mentioned six kinds of patterns filtered: when current entered the filter screen inboard outside filter screen, dirt was trapped within the outside of filter screen; When current flowed to the outside from filter screen is inboard, dirt was trapped within the inboard of filter screen.Although the direction difference that current pass filter screen when filtering, during the flushing filter screen, current all are along the screen surface side blow brush of holding back dirt, are with dirt down from the side, and current do not pass the filter screen that is rinsed.Therefore, the screen surface flushing is unclean, and washing time is also long.
Fig. 5,6,9,10 is depicted as the filter of Israel, and the rotatable filter screen of one deck is housed.Fig. 5,6 installs three row brushes additional in the filter screen periphery, during cleaning, and filter screen rotation shown in Fig. 7,8, dirt is rinsed on the one hand, is brushed down by brush on the one hand.Fig. 9,10 also is the rotatable filter screen of one deck, has installed sucker additional at the blowdown oral-lateral, during cleaning, and filter screen rotation shown in Figure 11,12, dirt flows to sewage draining exit under the effect of current flushing and sucker.These two kinds of forms, though added equipment, current are still along the screen surface flushing that is cleaned, and do not pass the crud layer flushing from the negative, so still flushing is not too clean, and increase energy resource consumption.
Also be the filter of Israel shown in Figure 13,14,15,16, the same filter characteristics shown in Figure 13,14 are double-layer leaching net, but can only clean outer filter, and inner filter screen need be removed end cap and take out and could clean, and two-layer filter screen can not be used alternatingly.As can be seen from Figure, identical with shown in Figure 13,14 of the same filter shown in Figure 15,16, the drainage box also need take out and could clean, and is very inconvenient.
Filter shown in Fig. 2,4,7 and 8,11 and 12,14,16, its flushing water source are not that the clear water after directly filtering with itself washes immediately, all are from the outside.Have plenty of with unfiltered water flushing; What have also need have one to overlap filter plant, is used for washing with filtering good clear water; Have plenty of with the clear water after filtration itself, introduce with a set of tubes system again.The two kinds of methods in back have all increased equipment, have also increased investment.Filter shown in Figure 16, the flushing water source also only is a water by the coarse filtration of drainage box, this water does not pass through the strainer filtering mistake identical with filter screen order number yet, still contain with filter screen on the same dirt of crud layer come crud layer on the side flushing filter screen.
The purpose of this invention is to provide a kind of novel filter.It can be realized: in same filter, the clear water after filtering with self oppositely (current pass the opposite flow direction of filter screen direction when filtering) passes screen pack, and dirt is taken out of by the current back flush.
The object of the present invention is achieved like this: a kind of filter, one current shunting switching device shifter is housed behind water inlet, this device connects two or more intake chambers, intake chamber all is equipped with filter screen, filter screen surrounds one or more water-supplying chamber, water-supplying chamber is provided with delivery port, and each intake chamber all has a sewage draining exit, and blowoff valve all is housed on it.
This filter can be two intake chambers, a water-supplying chamber, but current shunting switching device shifter three-way valve also connects the valve on intake chamber and the water inlet short tube.
During this filter operate as normal, blowoff valve cuts out, and water to be filtered enters from water inlet, by the control of current shunting switching device shifter, enters one, two, three or more intake chamber, behind the strainer filtering through going up separately, to water-supplying chamber, is discharged by delivery port.Each intake chamber all is connected to sewage draining exit, and blowoff valve is housed on the sewage draining exit.
In the above-mentioned course of work, dirt is intercepted on the screen wall of this side of intake chamber.
When the either side filter screen stops up, when needing flushing, regulate current shunting switching device shifter, close this side intake chamber inlet, open the blowoff valve on this side intake chamber, since blowoff valve open with atmosphere UNICOM after, the pressure of this side intake chamber just is significantly less than the delivery port operating pressure, and so, whole water to be filtered enter another respective side (or other several sides) intake chamber, by arriving water-supplying chamber behind the strainer filtering on another respective side intake chamber, will pass the filter screen of obstruction, enter this side intake chamber, discharge by sewage draining exit, the tamper that is blocked on the screen pack also is with down by current thereupon, is discharged by sewage draining exit.
Like this,, pass the obstruction filter screen by water-supplying chamber's one side and enter intake chamber one side, that is: realized in same filter with regard to the water after available filter self filtration, the tamper on the backward erosion screen pack, washing time is short, and clean.
When many sides screen pack has all stopped up, also can wash though divide as stated above.During flushing, can close outlet valve.
Advantage of the present invention is: owing to adopted this structure, during flushing: 1. dirt is oppositely gone out filter screen by the clear water after filter, the current flushing action is big, back flush is rinsed well than the side and the short water source that 2. washes of time is a clear water shortly past filter like this, in same filter, filter with flushing and carry out simultaneously, the effect of having played " with a generation two " 3. two (or a plurality of) filter screens can replace cleaning mutually, when not changing filter screen, generally speaking, need not to take apart, can carry out, simple, convenient.During filtration: the function of two (or a plurality of) filter screens is identical, can use separately, also can use simultaneously, also can be used on request.
