Description
Technical field:
The present invention relates to the fluid purification technology, relate in particular to liquid and remove particulate, clarifier, particularly a kind of combined polypropylene thermal spray fiber membrane folding type filter element.
Background technology:
Filters are used in removing in micro particle filtering and the application of other liquid purifying of the liquid of industries such as pharmacy fermentation, bioengineering, food and drink, modern chemical industry, electronics industry, environmental protection in a large number.Early stage filter is the plate and frame device, adopts geotextiles as filter medium, the energy consumption height, and the occupied ground area is big, and filtering accuracy is poor, and filter efficiency is low, and service life is short, and labour intensity is big.Bag filter has appearred later on, bag filter still adopts geotextiles as filter medium, though overcome plate frame filter energy consumption height, the occupied ground area reaches problems such as labour intensity height greatly, but still had the problem that filtering accuracy is poor, filter efficiency is low, service life is short.In the prior art; in filter, extensively adopt folding type filter element; folding type filter element adopts three-decker; middle one deck is a polypropylene thermal spray fiber membrane; upstream and downstream each use one deck bonded fabric as protective layer, and filtered fluid quality instability, filter efficiency can't guarantee, filter core short problem in service life but exist.
Summary of the invention:
The object of the present invention is to provide a kind of combined polypropylene thermal spray fiber membrane folding type filter element, filtered fluid quality instability, the filter efficiency that described this combined polypropylene thermal spray fiber membrane folding type filter element will solve folding type filter element existence in the prior art can't guarantee, filter core short technical problem in service life.
This combined polypropylene thermal spray fiber membrane folding type filter element of the present invention is by filtering medium layer; interior support tube and outer support tube constitute; described filtering medium layer is folded into the fin back wall on the excircle of interior support tube; support tube was axial in the fold line of filtering medium layer was parallel to; described outer support tube is set in the outside of the cylinder of filtering medium layer formation; wherein; described filtering medium layer is by the three-layer polypropylene thermal spray fiber membrane and two protective layers are superimposed constitutes; described three-layer polypropylene thermal spray fiber membrane order adjacency; described protective layer is separately positioned on the upstream side and the downstream of three-layer polypropylene thermal spray fiber membrane; two adjacent fins all are welded to connect arbitrarily; the upper end of support tube and outer support tube is welded with a upper end cover in described; the lower end of interior support tube and outer support tube is welded with a bottom end cover; be welded with an orientation triangle fin on the described upper end cover, the downside of described bottom end cover is welded with an interface pipe fitting.
Further, the excircle of described interface pipe fitting is provided with the O RunddichtringO.
Further, any one described protective layer constitutes by nonwoven fabric of long fibers.
Further, described three-layer polypropylene thermal spray fiber membrane is arranged with order from big to small by its nominal aperture.
Concrete, the welding described in the present invention can be adopted ultrasonic wave of the prior art or sweat soldering technology.
Operation principle of the present invention is: the three-layer polypropylene thermal spray fiber membrane is arranged with order from big to small by its nominal aperture, increased the pollutant holding capability of filter core, the descending progressively interception of particle interception mode, improved the durability against pollution of filter core, the filtering accuracy and the efficient of filter core have been guaranteed, thereby prolonged the service life of filter core greatly, and guaranteed the stable of filter liquide product quality.
The present invention and prior art compare, and its effect is actively with tangible.The present invention is provided with the three-layer polypropylene thermal spray fiber membrane in the filtering medium layer of folding type filter element; and utilize nonwoven fabric of long fibers protection filter membrane in both sides; increased the pollutant holding capability of filter core; the descending progressively interception of particle interception mode; improved the durability against pollution of filter core; guarantee the filtering accuracy and the efficient of filter core, thereby prolonged the service life of filter core greatly, and guaranteed the stable of filter liquide product quality.
