Description
Technical field
The present invention relates to filtration device structure, relate in particular to a kind of filter that can automatic backwash.
Background technology
Water conservation and using water wisely and people live closely bound up, and the recycling of water resource is particularly important.Water for industrial use, air-conditioning cooling circulating water, automobile circulating water, boiler feed water, bathing pool, well water, river etc. all need to carry out the filtration treatment of water, it is the only way which must be passed of water resource recycling, tradition seldom adopts by the method that chemical substance is filtered, mostly adopt physical cleaning method filter, remove by mechanical filter principle the middle impurity that anhydrates.Mechanical filter is the most frequently used equipment.Traditional mechanical filter, medium completes filtration through filter opening to filter screen outside from filter screen inner chamber, in this process, Impurity deposition is in filter screen bottom or invest on filter screen inwall, and the impurity that is slightly larger than filter opening is embedded in filter opening, along with increasing of filter medium, adhere to and to embed the impurity of filter screen more and more, until stop up, produce secondary pollution simultaneously, must clean or change filter screen.For addressing this problem, the most original method is to take out filter core to carry out manual cleaning, and workload is large, and cleaning quality does not guarantee, and filter process is discontinuous.For reducing wash number, also have the filter screen of the less mesh of employing, but filtering accuracy is low, poor filtration effect.
Summary of the invention
The object of this invention is to provide a kind of vertical high-voltage full-automatic backwash filter, there is excellent flushing performance, do not need dismounting, automatically complete flushing process.
For achieving the above object, the technical solution used in the present invention is:
A kind of vertical high-voltage full-automatic backwash filter, comprise inlet, cylindrical shell, front shroud, back shroud, screen pack, liquid outlet, soil chamber, described screen pack is that tubular construction is distributed in cylindrical shell, screen pack outside is provided with cleaning arm, clean on arm and have cleaning mouth, screen pack inner side is provided with soil pick-up arm, on soil pick-up arm, has pollution-absorbing nozzle; Clean arm and soil pick-up arm and be all communicated with central rotating shaft, central rotating shaft is hollow pipeline, is divided into blow-off line and pipe blow-through by dividing plate; There is clear water chamber cylindrical shell upper end, and clear water chamber is fixed on back shroud, and there is a water inlet side, clear water chamber; Upper end, clear water chamber is transmission device, and described transmission device is connected with central rotating shaft through clear water chamber; Transmission device upper end is connected with reductor, and described inlet and liquid outlet are provided with differential pressure transmitter, and differential pressure transmitter is connected with control device.
As a kind of preferred version of vertical high-voltage full-automatic backwash filter of the present invention, described pollution-absorbing nozzle has many groups with cleaning mouth, the parallel screen pack both sides that are installed on, can carry out omnibearing cleaning to screen pack, the impurity washing down enters soil pick-up arm through pollution-absorbing nozzle, discharges through the soil chamber of blow-off line end.
As a kind of preferred version of vertical high-voltage full-automatic backwash filter of the present invention, described cleaning arm and soil pick-up arm are fixed through U-shaped amalgamation hole connector and central rotating shaft by bolt, make up the welding error in process of manufacture, improved and clean precision, improved cleaning performance.In addition, dismountable structure alleviates that it is difficult in maintenance greatly, changes the problems such as difficulty is large.Clean arm and pipeline along with central rotating shaft back and forth and rotatablely move, screen pack is carried out to 360 degree are comprehensive to be cleaned without dead angle.Preferred cleaning arm and soil pick-up arm respectively have 2-6 bar, have improved the efficiency of cleaning and filtering net, have shortened scavenging period.
As a kind of preferred version of vertical high-voltage full-automatic backwash filter of the present invention, described transmission device comprises transmission cavity, two proximity transducers, power transmission shaft, rotating shaft, stroke video disc, rotating shaft and power transmission shaft are concavo-convex head design, described stroke video disc lower end is designed for screw-hole type, by bolt, stroke video disc, power transmission shaft, rotating shaft are fixed together, there is transmission nut on transmission cavity top.By the position of two proximity transducers and stroke video disc, control the forward and reverse of reductor.In the time of reductor forward, rotating shaft drives power transmission shaft rotation, stroke video disc moves to the first proximity transducer direction, when the distance of stroke video disc and the first proximity transducer reach limit apart from time, the first proximity transducer sends instruction to control device, reductor starts reversion, rotating shaft drives power transmission shaft opposite spin, stroke video disc moves to the second proximity transducer direction, when the distance of stroke video disc and the second proximity transducer reach limit apart from time, the second proximity transducer sends instruction to control device, reductor starts forward, until receive the out-of-work signal of control device.Central rotating shaft is rotated and moves back and forth under the drive of power transmission shaft, and filter screen is carried out to 360 degree cleanings.With the alternative mechanical trip switch of proximity transducer, avoid mechanical damage at the volley, proximity transducer, without contacting with parts, without damaging possibility, is put forward the high-precision use accident that simultaneously reduces.Described transmission device adopts lenticular structure, and is fixed with bolts, and has improved the service life of transmission device, reduces maintenance cost, improves maintenance efficiency.
As a kind of preferred version of vertical high-voltage full-automatic backwash filter of the present invention, described cleaning arm outside is provided with guide wheel, in the rotation of cleaning arm and reciprocating motion process, can avoid cleaning arm and the damage of cylinder inboard wall friction to equipment.
While using filter of the present invention to filter, clear water chamber is connected with high-pressure hydraulic pump, blow-off line is connected with sewage pump, and high-pressure hydraulic pump and sewage pump are all communicated with control device.Need the turbid media filtering to be entered in cylindrical shell by inlet, net filtration after filtration, medium is discharged by liquid outlet.Filter process along with screen pack on the increasing of impurity, the inflow-rate of water turbine of screen pack reduces gradually, the pressure of liquid outlet reduces gradually, now between inlet and liquid outlet, form a pressure differential, in the time that the pressure differential between inlet and liquid outlet reaches setting value, control device starts cleaning procedure, high-pressure hydraulic pump is pressed into water to clear water chamber, transmission device drives cleaning arm and soil pick-up arm rotate and move back and forth, impurity on filter screen enters pollution-absorbing nozzle under the High-Pressure Water that cleans mouth impacts, and enter blow-off line along soil pick-up arm, discharge by soil chamber.Because the impurity that screen pack adheres to is discharged, it is normal that the pressure of liquid outlet recovers gradually, in the time that the pressure differential between inlet and liquid outlet reaches setting value, control device stops cleaning procedure, transmission device quits work, complete a blowdown process, whole filter process carries out with cleaning blowdown process simultaneously, does not interfere with each other.
Beneficial effect:
Vertical high-voltage full-automatic backwash filter of the present invention, the impurity of the high-pressure water flow washing screen pack inner side spraying by cleaning mouth, does not need dismounting just can reach the object of cleaning; Cleaning arm and soil pick-up arm can rotate and move back and forth by 360 degree, can be comprehensively without the cleaning filter screen at dead angle, and cleaning performance is good.
