Reverse osmosis membrane filter element for solving problem of high TDS of first cup of water

Abstract

The invention discloses a reverse osmosis membrane filter element for solving the problem of high TDS of a first cup of water. The reverse osmosis membrane filter element comprises a filter bottle, afilter bottle cover, a bottom cover, two filter plates, a central pipe and a top cover, wherein the filter bottle is tubular, the top of the filter bottle is connected with the filter bottle cover ina covering manner, and a central hole is formed in the top of the filter bottle cover; the two filter plates are symmetrically distributed at a lower opening and an upper opening of the filter bottleup and down; each filter plate is composed of a round pipe, partition plates, an annular plate, a sealing groove and an outer annular plate, a plurality of partition plates are evenly distributed andinstalled on the outer side of the round pipe, the outer sides of the multiple partition plates are fixedly sleeved with the annular plate, a circle of sealing groove is formed in one end of the outerside of the annular plate, the outer annular plate is fixedly installed on the edge of the outer side of the other end of the annular plate, and an annular groove is formed between the outer annularplate and the annular plate; the bottom cover is fixedly connected to the inner wall of the bottom of the filter bottle. The reverse osmosis membrane filter element is beneficial to sealing, is also beneficial to separate discharge of wastewater and pure water, and has a good filtering effect.

Description

technical field [0001] The invention relates to the technical field of filtering equipment, in particular to solve the problem of a reverse osmosis membrane filter element with high TDS of the first cup of water. Background technique [0002] Common materials for reverse osmosis membrane filters are nitrocellulose, cellulose acetate and polyamide. The reverse osmosis membrane filter uses the selective permeability of the reverse osmosis membrane to only pass through the solvent (usually water) and intercept ionic substances or small molecular substances, and uses the static pressure on both sides of the membrane as the driving force to achieve the separation of liquid mixtures. membrane process. It has many advantages such as high water quality, low operating cost, no pollution, convenient operation and reliable operation. [0003] However, when the existing reverse osmosis membrane filter element is used, it is not conducive to sealing, and it is not conducive to the sepa...
