Background
The filter element of the filter can purify polluted media, achieves a clean state required by production and life, and has certain cleanliness. The filter element has a wide application range, and can be used in industrial production such as steel smelting, power production, ocean purification and the like, and can be used in domestic drinking water treatment, domestic garbage utilization, automobile combustion filtration, bicycle lubricating oil filtration and the like, so that the filter and the filter element are used in the cleaning technology in life. The water filter element is a novel precise filter element, has the characteristics of small volume, large filter area, high precision, no pollution, convenient installation and replacement and the like, and has small adsorption, no retention of filtrate, wide chemical compatibility and wide applicability due to the adoption of microporous membrane filtration.
The Reverse Osmosis (RO) membrane is an RO membrane, which is an abbreviation of English Reverse osmoses membrane, and Chinese means Reverse Osmosis (Reverse Osmosis), and the general water flow mode is that water flows from low concentration to high concentration, and after the water is pressurized, the water flows from high concentration to low concentration, namely the Reverse Osmosis principle. The water treatment filter element is the most advanced at present, the reverse osmosis membrane RO is made of cellulose acetate or aromatic polyamide and the like, the aperture of the reverse osmosis membrane RO can reach 0.0001 micron, tap water is pressurized through a high-pressure water pump, water molecules permeate from the side with high membrane concentration to the side with low membrane concentration, inorganic ions, bacteria, fungi, virosomes and the like cannot pass through the water molecules, and the water molecules, the bacteria, the viruses, the heavy metals, the pesticides and other harmful substances in water are removed along with waste water, and the purpose of direct drinking is achieved.
At present, in the existing production process of the household RO filter element, the manufacturing process of the filter element is carried out in series, and the production process specifically comprises the following steps:
firstly, a central tube of a filter element is arranged;
thirdly, rolling the membrane, namely arranging the central tube of the filter element at the innermost layer; then rolling the membrane onto the central tube of the filter element;
and thirdly, a blue leather winding step, namely winding the blue leather outside the membrane, and winding the filter element by utilizing the viscosity of the blue leather to prevent the filter element membrane from loosening.
From the above steps, it can be seen that after the filter element central tube is assembled on the processing equipment, the rolling of the filter element membrane and the winding of the blue skin are carried out around the central tube, and the whole manufacturing process is in series. However, the production speed of the production whole set of production line of the reverse osmosis membrane RO production filter element is about 40S/per unit, and the production efficiency is very low. The manufacturing mode of the series connection of the RO filter elements influences the manufacturing efficiency of the whole equipment.
