The utility model is a kind of does not block the filtration that high accuracy effluent filter is mainly used in difficult sewerage, it fully applies the advantages such as spiral-flow filter separating suspension, impurity, particle, silt, on the basis of spiral-flow filter system, increase filtration system and on-line automatic back cleaning system and realize required function.
Form primarily of sintered metal mesh 3 in the utility model filtration system, one end of sintered metal mesh 3 adopts the sealing of round end sintered metal mesh, other end welding standard flange.Select the sintered metal mesh of different filtering accuracy according to the requirement of filtering water standard, according to precision, the parameter such as water outlet caliber and flow velocity of screen pack, select the length of suitable sintered metal mesh.Sintered metal mesh main feature is that filtering velocity is high, and filter area is large, and birthday noodle are long, have high mechanical strength and compressive resistance.Processing, welding and assembling property are good, easy to use.Filtering accuracy all can reach the strainability of uniformity, ensures that it has high stability.Sintered metal mesh good corrosion resistance, good heat resistance, can be used for-200 DEG C ~ temperature of 480 DEG C and the filtration of acid or alkali environment.There is the both surface filtration structure of splendid backwash effect, so backwash effect is good, can Reusability, the life-span is long.
There is in the utility model pressure wash system, the flange of sintered metal mesh 3 filter is provided with supporting sleeve, namely the pressure disc 51(of cleaner 5 clears up head) can be moved up and down by transmission mechanism 6 driving inside sintered metal mesh 3, and there is certain pressure.The drive link 50 of cleaner 5 has blind flange and sealer sealing, prevents from leaking.Cleaning head there is check sheet, when pressure disc 51 moves upward under the driving of transmission mechanism 6, check sheet is closed, pressure of purifying waste water above pressure disc 51 increases, a water part for filter interior flows into outlet pipe 8, some produces pressure under the driving of pressure disc 51, the water of filter interior is oppositely gone out, reaches the object of cleaned filter.Cleaned fall dirt and foreign material taken to the edge of cyclone body 1 by eddy flow, and along wall sink, until store up dirty device 9 li.When pressure disc 51 moves downward, check sheet is half-open to keep water flow, and the pressure of purifying waste water below pressure disc 51 increases, and the water of filter interior produces pressure under the driving of cleaning head, the water of filter interior is oppositely gone out, reaches the object of cleaned filter.Such cleaning head back and forth moves up and down under the driving of transmission mechanism, under the prerequisite keeping output flow, achieves the object of real-time automatic on-line cleaning.
According to the feature of metre filter fluid and the difference of dirt adhesive force, cleaning head can add different functions again, such as, can lead to water under high pressure carry out backwash in face in front of clearing up, or adds ultrasonic energy clearing up face in front, carries out ultrasonic backwash.
In the utility model, there is high pressure water cleaning system: when only having pressure wash system cannot meet actual cleaning requirement, the cleaner 5 in filter core superposes high pressure water cleaning system.Pressure disc 51 has several high pressure water jets loopholes, drive link 50 is provided with water under high pressure passage and interface, at the top installation high-voltage pump (that is, water under high pressure generator 4) of cyclone body, the outlet pipe of high-pressure pump is connected with the water under high pressure channel interface on drive link 50 top.The operation of high pressure water cleaning system can be carried out in real time, also can be undertaken by programme-control.When cleaner moves up and down under the driving of transmission mechanism, water under high pressure is from clearing up face injection at a high speed in front, due to jet slabbing, the cross section local pressure of filter is very large, very large shearing force is produced to filter, the cleaned outside to filter of dirt in capillary gap, then sink in the dirty device of storage with eddy flow.
Also there is ultrasonic cleaning system in the utility model: when only having pressure wash system and high pressure water cleaning system cannot meet actual cleaning requirement, cleaner 5 in filter core can superpose ultrasonic cleaning system again, at the middle part of cleaning head, ultrasonic transducer is installed, drive link 50 is provided with ultrasonic wave lead channels and interface, install ultrasonic signal generator 7 in the side of cyclone body 1, ultrasonic signal generator 7 output signal line is connected with the conductor interface on drive link 50 top.The operation of ultrasonic cleaning system can be carried out in real time, also can be undertaken by programme-control.When cleaner moves up and down under the driving of transmission mechanism, ultrasonic energy is by the pressure disc ultrasonic exciting face 53(steel plate of pressure disc 51 lower end side) be radiated in water, because Ultrasonic Radiation face is closely connected with the inwall of screen pack, the ultrasonic energy that filter bears can be very large, extraordinary ultrasonic cleaning function is produced to filter, dirt in capillary gap thoroughly can be cleared up to the outside of filter, then sinks in the dirty device of storage with eddy flow.
Above-mentioned three kinds of cleaning functions work simultaneously, and add the feature of sintered metal mesh easy cleaning, one of the present utility model does not block high accuracy effluent filter, no matter can realize completely not blocking under any adverse circumstances, the function of high-precision filtration.
Research finds, filter core is when implementing to filter, first pollutant fills up the capillary gap of filter core, and then form filter cake in the outside of filter screen, the hardening time of the pollutant in knitting wool gap is generally about 30 minutes, the anti-scavenging period of current automatic anti-filter rinsed is generally all greater than this time, and the energy of adding anti-cleaning is inadequate, so effect when cannot ensure anti-cleaning.The advantage of real-time automatic on-line cleaning of the present utility model is the dirt removed in time on filter, clears up in time, reach the object that cleaning dirt is thoroughly clean when the dirt when dirt does not also have enough time to adhere to solid or in capillary gap does not also deposit blocking.Otherwise, by the time filter blocked up by dirt generation pressure difference signal time carry out backwash again, now thoroughly can not remove the dirt in capillary gap, the dirt that some adhesive force are unreal can only have been removed.
Because the quantity of sand and mud in oilfield process is very large, the capacity of the dirty device of storage of general cyclonic separation is large not, and filled up by silt very soon, the capacity storing up dirty device in the utility model is large, and be furnished with magnetic valve, can automatic-discharging silt under the control of automatic control signal.
Here description of the present utility model and application is illustrative, not wants by scope restriction of the present utility model in the above-described embodiments.Distortion and the change of embodiment disclosed are here possible, are known for the replacement of embodiment those those of ordinary skill in the art and the various parts of equivalence.Those skilled in the art are noted that when not departing from spirit of the present utility model or substantive characteristics, the utility model can in other forms, structure, layout, ratio, and to realize with other assembly, material and parts.When not departing from the utility model scope and spirit, can other distortion be carried out here to disclosed embodiment and change.
