Description
Technical field
The utility model belongs to a kind of technical field of sewage treatment equipment, and a kind of polishing filter be used to containing impurity sewage specifically is particularly with the self-cleaning filter of back suction scrubbing structure.
Background technology
The filter plant of sewage treatment industry is usually seen and be widely used in to the filter right and wrong, be mainly used in the aspects such as processing of Sewage Plant, waterworks and industrial colling, concrete effect is that the interception function by certain precision filter screen comes in the trap water Solid Suspension material greater than certain physical dimension.Its main working process comprises the particle interception and removes two links that wherein intercept process is substantially in full accord, all be to have utilized work principle of filter, and the removal process is varied, and is different.
The multiple defects such as the interception removing method of same kind of domestic equipment mainly contains the artificial removal and automatically removes dual mode at present, and is large owing to artificial removal's workload, that efficient is low are not suitable for using in the occasion of the large traffic filtering of needs; And the product of automatically removing mainly contains three kinds of patterns, specifically comprises: (1) backwash mode; (2) hairbrush brushing type; (3) back suction suction.Although all substantially can satisfy instructions for use on principle, particularly different, particularly front two kinds in use still come with some shortcomings, and are embodied in:
Mode (1) adopts backwash mode, has seen with practical conditions endogenous backwash and external source backwash dual mode.At first, the external source backwash needs extra increasing to add source of clean water, and this is very restricted in a lot of application scenarios; And endogenous backwash generally all requires combination of filters to use, mutually utilize separately water outlet to carry out back flush as the backwash water water source, the problem of its existence is that the device of backwash must stop to filter, and also will consume simultaneously the rear water of part filter of other equipment, is not very economical so consider.
Mode (2) mainly adopts hairbrush to scrub, and according to the operating experience of reality, although hairbrush is scrubbed the problem that has solved mode (1), has occurred again other problem simultaneously.Comprise: parts of fine fubril thing can be stuck on the filter screen under the squeezing action of hairbrush, and hairbrush can twine a large amount of fibre object in use for some time simultaneously, affects washing effect and filter efficiency, finally must clear up by the artificial unloading.
Mode (3) is a kind ofly reasonablely to go the filter residue mode, but the structure of existing back suction suction device mostly is complicated, the control underaction.
Therefore, based on above deficiency, need to reasonably improve the filter residue removing method, what propose a kind of better effects if can be from the filter of clear filter residue.
The utility model content
The purpose of this utility model is in order to solve the problems of the technologies described above, a kind of self-cleaning filter is proposed, this is a kind of filter of removing system with filter residue, can convert at original filter, improved the removal effect of filter residue, automatically control neatly, greatly improved the efficient of sewage water filtration, reduced operating cost.
The purpose of this utility model is achieved through the following technical solutions:
A kind of self-cleaning filter is provided with filter cartridge, inlet tube and outlet tube, water-in and water-out valve, and screen pack is characterized in that: the cylindrical shape of described filter cartridge and screen pack, and the filter cartridge lower end is communicated with water inlet pipe, and the side is communicated with outlet pipe; Screen pack is arranged in the filter cartridge, be communicated with water inlet pipe in its net, its net is outer to be communicated with outlet pipe, central longitudinal is to being provided with a soil pick-up supervisor in this screen pack, this soil pick-up supervisor's periphery is provided with several and is spaced, the soil pick-up arm of horizontally set, this soil pick-up arm outer end opening and close screen pack inwall, the inner end is communicated with the soil pick-up supervisor; Be provided with blowdown chamber and sewage draining valve in the upper end of described filter cartridge, described soil pick-up supervisor's lower end closed also stretches in the water inlet pipe, the upper end also is provided with opening, and drive back suction that the soil pick-up supervisor moves up and down and rotate simultaneously and move leading screw and be connected with one, this leading screw is connected with a back suction drive motors power.
The utility model further improves and the additional project of enforcement is:
Described leading screw upper and lower limit bit switch.
Be provided with pressure difference switch, the back suction drive motors control connection of this pressure difference switch and sewage draining valve and driving leading screw.
Between described water inlet pipe and outlet pipe, be provided with the leap valve, close this valve when sewage need to filter, open this valve when not needing to filter.
During the utility model operation: at filtration stage, water inlet, flowing water Valve are opened, cross over valve closing, former water is discharged through after the filtration of filter screen, and As time goes on, the dirt of tackling on the filter screen is more and more, cause the decline of filter effect, and then so that the inside and outside pressure reduction of filter screen becomes large, pressure difference switch sends signal to blowoff valve and back suction drive motors when pressure reduction reaches setting value, enters into slag removal.The back suction drive motors drives leading screw rotation and lower mobile, the back suction arm is under the drive and the differential pressure action inside and outside the screen pack of leading screw, from descending to descend or absorb from top to bottom the dirt that is trapped on the screen pack, after leading screw runs to upper limit position switch, drive motors stops, and system delay is to setting value rear drive motor backward rotation, and leading screw is made reverse mobile suction pipe and repeated to inhale the mud process, stop until leading screw runs to lower limit, finish one and inhale the mud cycle.Concrete suction mud time user can rule of thumb set.Suction mud finishes, and mud valve is closed, and enters next circulation.
Characteristics of the present utility model are: (1) does not stop to filter at Suction stroke, does not affect outlet effect; (2) the relative treating capacity of the back suction water yield is very little, does not affect water; (3) the back suction slagging-off is more thorough, does not exist fiber to be stuck in the situation of filter screen, and operational effect is better.In a word, it is more reasonable to the utlity model has structure, design is more optimized, easier processing, greatly reduced the quantity of shower nozzle, reduce and produce and manufacturing cost, particularly provide great convenience for high throughput, the abominable occasion of water quality, and effect and efficient that decontamination is filtered improve greatly.
