The minimum point of described water inlet pipe is provided with atmospheric valve.
Described outlet pipe is provided with the operation outlet valve; Also be provided with backwash intake valve and pressure sensor on the outlet pipe.
Described water inlet water-locator is provided with some fishbone arms.
The floating type filter of this adverse current adopts and is just washing water intaking valve, just washes out the bridge-type water route that water valve, backwash water intaking valve and backwash outlet valve are formed, and is that it is opened and closed combination reaches the direction that water enters tank body, thereby reaches the purpose of positive and negative cleaning packing layer.
Described water inlet water-locator is provided with some fishbone arms, thereby has guaranteed that the water that the water inlet water-locator flows out is uniform stratosphere, improves filter effect.
Description of drawings
Fig. 1 is the general illustration of the utility model embodiment.
Fig. 2 is the internal structure schematic diagram of the utility model embodiment.
The specific embodiment
As shown in Figure 1, the floating type filter of a kind of adverse current comprises tank body 1, and the top outside tank body 1 connects an end of outlet pipe 13, and the other end of outlet pipe 13 is connected in parallel and just washes out water valve 2 and backwash water intaking valve 3; Bottom outside tank body 1 connects an end of water inlet pipe 12, and the other end of water inlet pipe 12 is connected in parallel and just washes water intaking valve 5 and backwash outlet valve 8, is just washing the other end of water intaking valve 5 and the other end of backwash water intaking valve 3 and is being connected to form water inlet 4 jointly; The other end of backwash outlet valve 8 is connected to form the positive and negative water pipe 16 that washes out jointly with the other end that just washes out water valve 2, and the positive and negative water pipe 16 that washes out connects blowoff valve 9; Top in tank body 1 is provided with water outlet water-locator 18, and links to each other with outlet pipe 13, and the bottom in the tank body 1 is provided with into water water-locator 17, in tank body 1 adrift density less than the filtrate 20 of water.
The minimum point of described water inlet pipe 12 is provided with atmospheric valve 10.
Described outlet pipe 13 is provided with operation outlet valve 6; Also be provided with backwash intake valve 15 and pressure sensor 7 on the outlet pipe 13.
Described water inlet water-locator 17 is provided with some fishbone arms 19.
This device filtration state: PLC control backwash outlet valve 8, backwash water intaking valve 3, just washing out water valve 2, atmospheric valve 10 and backwash intake valve 15 are closed, just washing water intaking valve 5, atmospheric valve 10 and operation outlet valve 6 are opened, current enter through water inlet 4 and just wash water intaking valve 5, enter tank body 1 from the bottom of tank body 1, by water inlet water-locator 17 and the fishbone arm 19 on it, with the packing layer in the state arrival filter that flows near par, this packing layer is the filtrate 20 of density less than water, so filtrate 20 swims in the tank body top, simultaneously the impurity in the water is filtered, impurity promptly is trapped within the packing layer, water after the filtration collects and enters outlet pipe 13 uniformly by water outlet water-locator 18, and, promptly filter and finish from 6 outflows of operation outlet valve.
This device is just being washed state: PLC control backwash outlet valve 8, backwash water intaking valve 3, atmospheric valve 10, operation outlet valve 6 and backwash intake valve 15 and is being closed, just wash water intaking valve 5, atmospheric valve 10, just washing out water valve 2 and blast pipe 14 is opened, mobile direction of water and filtration state consistency, but because operation outlet valve 6 is closed, water flows out from the positive and negative mouth of a river 16 that washes out through just washing out water valve 2.
This device backwash state: just washing water intaking valve 5, operation outlet valve 6, just washing out water valve 2, atmospheric valve 10, air bleeding valve 14 and close by PLC control, backwash water intaking valve 3 and backwash outlet valve 8 are opened, and backwash intake valve 15 is interrupted to be opened, current enter tank body 1 top by water inlet 4 through backwash water intaking valve 3, flow out from the bottom of tank body 1 again, flow out from the positive and negative mouth of a river 16 that washes out through backwash outlet valve 8.
Along with the impurity of holding back is constantly built up in packing layer, pressure head pressure reduction will constantly increase.When pressure reduction arrived certain setting limit value, pressure sensor 7 detected pressure difference value and passes to PLC, and when exceeding set definite value by calculating, system will be converted to the backwash state automatically, the impurity that is accumulated with cleaning.Concerning system, the impurity that regular backwash is accumulated with removing is necessary.
In filtration system, the water-locator of particular design and backwash intake valve 15 make packing layer form impingement flow when the backwash state, wash by rubbing with the hands mutually between the filtrate, improve backwash efficient to greatest extent, reduce needed backwash water, do not run filler during backwash simultaneously.When backwash finished, valve returned to again and is just washing state, and then other filter elements then enter the cleaning state successively.After just washing end, the floating type filter of this adverse current can reenter normal filtration work.
