As shown in Figure 5 and Figure 6, described pair of net formula filter element comprises:
The filter element housing is seal casinghousing, is divided into four parts in the housing, and the middle part is chamber, secondary filter back, and the upside of chamber, secondary filter back is a secondary filter cup, and the downside of chamber, secondary filter back is from decontamination chamber 37, and the opposite side of chamber, secondary filter back is chamber, three filter backs.Corresponding tubular filter screen and three screen location are provided with for each the draping lid and three filters that pick and place, clear up each filter screen and cover 36 on the housing of decontamination chamber and outside, three filter backs.The blast pipe 19 of band check valve is established in filter element housing upper end, and the effect of blast pipe is the gas in the unidirectional discharge filter element housing;
Tubular filter screen 43, be the cylindric filter screen of both ends open, each tubular filter screen connects chamber, secondary filter back upper and lower side, and a port of each tubular filter screen is by the water inlet 25 secondary filter cup that communicates, the another port of each tubular filter screen communicates from decontamination chamber, communicates with decontamination orifice by decontamination valve from decontamination chamber.Described tubular filter screen is 100~150 mesh filter screens.Described tubular filter screen quantity is at least 2.Tubular filter screen quantity can be respectively equipped with several according to sewage load and net footpath size;
Three filter screens 33 are positioned at chamber 34, three filter backs, communicate with chamber, secondary filter back by minute water plate 32.The space that communicates of dividing water plate partition to filter chamber, back and chamber, secondary filter back for three times, branch water plate is provided with water hole, and the water hole on the branch water plate adopts dredges upward close distribution down, is beneficial to evenly water.Described three filter screens are 40~100 mesh filter screens;
From sewage disposal apparatus, constituted by motor 13, driving wheel 27, driven pulley, axle sealing 26, shaft coupling 29, brush holder support axle 39 and the bristle 41 that is positioned on the brush holder support axle.Bristle is distributed on the brush holder support axle, and the brush holder support axle is positioned at each tubular filter screen, and brush holder support axle one end is connected with cleaning brush power transmission shaft 30 by shaft coupling.Motor drives driving wheel driven transmission wheel 12,31 by motor shaft 28 and drives each cleaning brush power transmission shaft rotation.The other end apical grafting of brush holder support axle is in the axle bowl of each draping lid that correspondence is provided with.Tooth-like or the cross piece formula shaft coupling of shaft coupling for moving.Seal with sealing ring 38 between each draping lid and filter element housing and each the tubular filter screen.Filter for three times between lid and filter element housing and three filter screens and seal with sealing gasket 35.
As shown in Figure 6, obviously, drive each cleaning brush power transmission shaft through each driven pulley of driving-belt 44 transmissions and rotate can also driving driving wheel by motor shaft from the motor described in the sewage disposal apparatus.
During use, high water level sewage is introduced the import of high water level sewage.Water-collecting tray with low water level lifting filter is accepted low water level sewage.For example during shower, the shower people stands on the water-collecting tray, foot-operated blowoff valve and foot-operated deluge valve on this moment water-collecting tray middle part concave surface are all normally closed, the shower wash water as cross dirt then shower human pin step on and open foot-operated blowoff valve and then cross sewage and enter the sewer sewage draining exit along water-collecting tray.Open the lifting water inlet that foot-operated deluge valve is introduced available sewage low water level lifting filter otherwise then tramp with one's feet down.When starting the lifting motor, available sewage enters filter cup in the filter housing by the lifting water inlet, filter through the filtering holes on the filter cup wall of cup again, after the filtration to flow to filter back than clean and dirt water indoor again in the lifting delivery port flows into the lifting pump housing, pump the mouth of a river through the supercharging of lifting pump through lifting and discharge the low water level sewage import that the lifting pump housing enters two net formula filter elements.
The sewage that utilizes again that is entered two net formula filter elements by import of low water level sewage and the import of high water level sewage all carries out refiltering for 2 times within it.
At this moment, decontamination orifice of the present utility model is communicated with sewer pipe, pump is communicated with sharp again water tank, closes decontamination valve sealing decontamination orifice, opens pump.The secondary that the pump draft will be washed in utilized sewage that dish, laundry secondary water and low water level lifting filter the send into two net formula filter elements in import of low water level sewage and the high water level sewage import suction body is filtered cup, after entering impurity such as filtering fiber fines in each tubular filter screen by each water inlet again, enter chamber, secondary filter back, enter and behind three strainer filterings, enter through sharp water conduit and pump valve again through a minute water plate current-sharing again and enter again sharp water tank in the pump after the supercharging again from chamber, three filter backs.Sharp again water tank can connect the lavatory flushing water tank and make wash water.
After using a period of time, should earlier the lid at filter housing top be opened, upwards mention handle and filter cup is taken out filter housing and clear up at first to the cleaning of low water level lifting filter.
Cleaning to each tubular filter screen of two net formula filter elements is to start from sewage disposal apparatus, close pump valve and pump, still the sewage import is injected and to utilize sewage or clean water, open decontamination valve and open decontamination orifice, open from the release knob of removing contamination and open motor, motor drives each driven pulley of driving wheel transmission by motor shaft and drives each cleaning brush power transmission shaft and rotate the brush holder support axle that is positioned at each tubular filter screen is rotated, and the bristle on it can be brushed to enter from decontamination chamber in the sewage in each tubular filter screen again and discharges two net formula filter elements along decontamination orifice sticking to impurity in each tubular filter screen.
Also can manually clear up or change each tubular filter screen, open that each draping lid takes out each tubular filter screen and interior brush holder support axle cleaning gets final product.Cleaning to three filter screens of two net formula filter elements is also like this, so be not repeated.
In a word, the utility model adopts the multi-path sewage filtration system, and integrated compact setting of body, and it is little to have a volume, installs and uses simply, and filter screen can make things convenient for mechanical self-walking to clean good filtration effect, the significant advantage of economizing on water.
