Abstract
The utility model relates to a winding type self-cleaning filter which comprises a casing, filter winding pipes, a cleaning pipe, cleaning nozzles, a piece of filtering cloth, a liquid inlet, a blow-off pipe and hollow shaft outlets, wherein the filter winding pipes are axially and parallelly erected in the casing; the two filter winding pipes are wound with the filtering cloth simultaneously, and a tight suspension section is reserved in the middle; the cleaning pipe extends from one end of the casing; a plurality of cleaning nozzles are arranged on the pipe and face the suspension section of the filtering cloth; the liquid inlet extends into the casing in the radial direction of the casing, and the blow-off pipe extends out from the other side; and the hollow shaft outlets are formed in the ends, extending out of the casing, of the filter winding pipes. Compared with the prior art, the winding type self-cleaning filter has the benefits as follows: extremely fine particles and impurities in the liquid can be effectively filtered by the multi-layer wound filtering cloth, the filtering cloth can be thoroughly cleaned at any time, so that filter material consumption is greatly reduced, and the winding type self-cleaning filter is simple in structure, stable in filter effect, low in cleaning loss and long in service life.
Description
Technical field
The utility model relates to filtering separation device, particularly a kind of wound form self-cleaning filter.
Background technology
Commercial filtering separation device has several classes at present, comprises individual layer filter screen (filter cloth) filtration, Filament-wound Machine filtration and media filtration etc.It is all single layer filter that Bag filter and stainless (steel) wire filter, single layer filter is simple, at the bottom of equipment cost, but because be individual layer, so it is few to hold dirt impurity level, cloth bag needs frequent replacing, although stainless (steel) wire can clean easily automatically, filtering accuracy very low (>100 micron).Filament-wound Machine filters comparatively speaking that pollutant holding capability is large, filtering accuracy is higher, but cannot reuse, and can only regularly manually change.The filter effect of media filtration is unstable, and expends a large amount of filtrates.Also have a kind of novel automatic backwash fabric filter, be similar to media filtration, by the fiber filter pressing closely, when backwash, open and loose fiber, make it easy to clean, this fabric filter exists filter effect unstable equally, and the halfway problem of backwash.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of wound form self-cleaning filter is easily and effectively provided, and it is simple in structure, filter effect is stable, and cleaning loss is low, long service life.
In order to address the above problem, the utility model by the following technical solutions:
Wound form self-cleaning filter, comprise housing, filter winding pipe, scavenge pipe, washer jet, filter cloth, liquid-inlet, blow-off pipe and hollow shaft outlet, described filtration winding pipe axially parallel is erected in housing, filter cloth is wrapped in 2 simultaneously and filters on winding pipe, one section of unsettled section of tightening is left in centre, scavenge pipe stretches into from housing one end, pipe is provided with multiple washer jets, washer jet faces unsettled section of part of filter cloth, liquid-inlet housing radially a side stretch into, blow-off pipe is stretched out by opposite side, one end that filtration winding pipe stretches out housing is hollow shaft outlet.
Described filtration winding pipe is porous screen casing, and two ends are established axle journal and are erected in housing sidewall, and it is hollow shaft that axle journal is stretched out in one end.
Described filtration winding pipe is 2 and is set up in parallel, and can, around axis synchronous rotary, realize the winding of filter cloth and open.
Described filter cloth is wrapped on screen pipe with multilayer form.
Described scavenge pipe is provided with multiple washer jets, and washer jet filters between winding pipe at 2, faces filter cloth unsettled and that tighten.
Compared with prior art, the beneficial effects of the utility model are:
The multi-lay winding filter cloth of the utility model wound form self-cleaning filter is imperceptible granule foreign in filter liquide effectively, and can thoroughly clean filter cloth at any time, greatly reduced the consumption of filter material, simple in structure, filter effect is stablized, and cleaning loss is low, long service life.

In figure: 1. housing 2. filters winding pipe 3. scavenge pipe 4. washer jet 5. filter cloth 6. liquid-inlet 7. blow-off pipe 8. hollow shaft outlets
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
See Fig. 1-Fig. 2, it is the structural representation of the utility model wound form self-cleaning filter, comprise housing 1, filter winding pipe 2, scavenge pipe 3, washer jet 4, filter cloth 5, liquid-inlet 6, blow-off pipe 7 and hollow shaft outlet 8, described filtration winding pipe 2 is that 2 and axially parallel are erected in housing 1, filter cloth 5 is wrapped in 2 simultaneously and filters on winding pipe 2, one section of unsettled section of tightening is left in centre, scavenge pipe 3 stretches into from housing 1 one end, pipe is provided with multiple washer jets 4, washer jet 4 faces unsettled section of part of filter cloth 5, liquid-inlet 6 radially stretches in housing from housing 1, blow-off pipe 7 is stretched out by opposite side, one end that filtration winding pipe 2 stretches out housing 1 is hollow shaft outlet 8.
When work, microscler banded filter cloth 5 two ends symmetries with the wrapped of multi-lay winding at 2 outer surfaces that filter winding pipe 2, the liquid that contains impurity enters in housing 1 by liquid-inlet 6, the filter course being wound around through multilayer filter cloth 5 filters, and pure liquid flows out from the hollow shaft outlet 8 of filtering winding pipe 2 one end.It is thicker that multilayer filter cloth 5 is wound around formed filtering layer, forms the intercept layer with depth, can effectively stop and receive fine impurity, ensures filtering accuracy and stable filter effect.Along with the carrying out of filtering, impurity constantly accumulates, filtering layer forms saturated, at this moment closing liquid is imported and exported switch, open the sewage draining exit switching evacuation liquid on blow-off pipe 7, keep sewage draining exit opening, the valve of opening on scavenge pipe 3 makes cleaning liquid flow into scavenge pipe 3, wash away by multiple washer jet 4 ejections, clean filter cloth 5, at this moment 2 filtration winding pipe 2 are synchronously turned clockwise until filter cloth 5 is all wound on left side filtration winding pipe 2, and then be rotated counterclockwise and filter cloth 5 is all wound into right side filters on winding pipe 2, make filter cloth 5 again symmetry be wrapped in two and filter (returning to original state) on winding pipe 2, in this process, the all surface of filter cloth 5 all thoroughly cleans through twice.After cleaning finishes, close liquid in imported valve, the emptying housing 1 of scavenge pipe 3, close blow-off pipe 7 sewage draining exit switch, open liquid entrance switch and can restart to filter.
