Description
Technical Field
The invention relates to water filtering equipment, in particular to filter element production equipment.
Background
The water purifier generally adopts a reverse osmosis filter core, and the reverse osmosis filter core can filter organic matters, colloid, bacteria, viruses and other impurities in raw water, and particularly has extremely high filtering efficiency on inorganic salts, heavy metal ions and other impurities. The filtering effect of the water purifier is directly related to the filtering effect of the reverse osmosis filter element. The reverse osmosis filter element comprises a central tube and a reverse osmosis membrane bag wound on the central tube, wherein the reverse osmosis membrane bag is formed by gluing and opposite adhesion of a membrane element.
The patent document with application publication number CN 111644064A discloses a method for producing a water treatment assembly based on membrane separation technology, comprising the following steps: step one: cutting the filtering membrane into a plurality of membranes, and simultaneously cutting the grid cloth into a plurality of grid sheets; step two: folding the membrane obtained in the first step in half from the center; step three: placing the grid sheet obtained in the first step between the folded membrane sheets obtained in the second step, thereby obtaining a filter membrane unit; step four: cutting the diversion cloth into diversion cloth sheets; step five: at least one layer of flow guiding cloth sheets and at least one layer of filter membrane units are sequentially and alternately wound on the perforated central tube to obtain a filter element; step six: winding a fixing adhesive tape on the outer surface of the filter element obtained in the step five; step seven: coating an adhesive layer on the outer surface of the filter element with the fixed adhesive tape; step eight: end covers are arranged at two ends of the filter element.
And step five, before the step five, the filter membrane unit is required to be overlapped with the flow guiding cloth sheets, and then the overlapped filter membrane unit and the flow guiding cloth sheets are wound on the perforated central tube, so that at least one layer of flow guiding cloth sheets and at least one layer of filter membrane unit are sequentially and alternately wound on the perforated central tube, and the filter element is obtained. The filter membrane unit comprises folded membrane sheets and grid sheets arranged between the folded membrane sheets, wherein the membrane sheets and the grid sheets are in a loose state without bonding relation. In the process of displacing and superposing the filter membrane unit on the flow guiding cloth sheet, if the filter membrane unit is adsorbed by the suction nozzle, the filter membrane unit is displaced, and the grid sheet is easy to displace relative to the membrane in the displacement process because the membrane is adsorbed by the suction nozzle. If the clamping jaw is used for clamping the filter membrane unit, as the clamping jaw is an upper clamping jaw and a lower clamping jaw for clamping the filter membrane unit, when the filter membrane unit is released, the lower clamping jaw needs enough movable space, the movable space enables the filter membrane unit to be in a vacated state, and the vacated filter membrane unit floats downwards to a preset position, so that the effect of accurate placement is difficult to achieve.
