Technical field

The invention belongs to filter bag preparation technical field, a kind of particularly oil suction decolorization filtering bag and preparation method thereof.

Background technique

Filter bag classification: mainly include two classes: liquid filter bag, air filter bag, as filter element, filter bag, which draws, is One ring of key in filter process, filter bag quality largely determine that user has filter effect, can targetedly expire The application of sufficient every field, filter bag made of polytetrafluoroethylene (PTFE), has the effect of filtering well, tetrafluoroethene, has excellent Good chemical stability, corrosion resistance, sealing property, high lubrication, non-stickiness, electrical insulation and good anti-aging endurance, uses workmanship Engineering plastics, polytetrafluoroethylene (PTFE) have the characteristics that resistant to high temperature, its coefficient of friction is extremely low, so after lubricating action being made, it can also Applied to the higher corrosion resistant pipeline of performance requirement, container, pump, valve and radar processed, high frequency communications equipment, radio component parts Deng.

If number of patent application (CN201710519869.0) discloses a kind of PP filter bag, PE filter bag opens up strength filter bag Using advanced hot-melt technology, guarantees that filter bag possesses best bond strength, prevent to leak.Linear slit.Open up the sewing of strength filter bag Extremely rigorous, firm and durable performs to the sealing effect that linear slit engages ultimate attainment.Pure thread is without the profit such as any silicone oil Lubrication prescription composition has evaded secondary pollution problem existing for common sewing filter bag, and filtering accuracy range is micro- from 0.6 micron to 200 Rice, material are divided into the filter bags such as polyester, polypropylene, nylon, and stainless steel and zinc-plated steel ring argon arc welding technology, diameter error are only small In 0.4mm, horizontal error is less than 0.1mm, selects the filter bag installation of this steel ring production that seal degree can be improved in a device, Reduce the occurrence probability of side leakage.

But existing filter bag has the disadvantage that during making and using

Existing filter bag is cut again after filter bag material to be made to filtering bag body during the preparation process, due to The volume of filter bag material is big, causes the preparation difficulty for filtering bag body time-consuming and laborious greatly, simultaneously for the waste of filter bag material Than more serious, and the cutting of filtering bag body after molding needs to cause by manual hand manipulation the labor intensity of operator Greatly；

Existing filtering bag body is usually that Filter-bag carcass is arranged at the both ends of filtering bag body to be supported guarantor to filtering bag body Shield, but the Filter-bag carcass for filtering bag body both ends cannot play support protective action well for filtering the bag face of bag body, lead Filtering bag body is caused to be easy to happen damage in use；

The filtering function of existing filtering bag body is single, narrow application range, the grease and pigment summarized generally for solution It not can be carried out effective filtering, there is biggish limitation.

Summary of the invention

The purpose of the present invention is to provide a kind of oil suction decolorization filtering bags and preparation method thereof, by inner layer adsorption layer and outer layer Protective layer overlapping is placed on the table, by the orientation cutting of fixed quantity of cutting wheel, avoids the waste of filter bag raw material；Pass through It is added on internal layer adsorption layer with the outer protective layer of stainless steel fibre sintering carpet veneer support, stainless steel fibre is made to be sintered carpet veneer pair Entire inner layer adsorption layer plays support protective effect；By the hydrophobic oleophilic oil of polypropylene fibre, realize that filtering bag body is preferably inhaled Oiliness plays suction-operated to the pigment molecule in filtrate by the adsorptivity of activated carbon fibre, realizes that filtering bag body is preferably de- Color, to solve the problems mentioned in the above background technology:
