Problems solved by technology

At present, most of the faucet water purifier filter elements used by people use a single external pressure ultrafiltration membrane. Since the ultrafiltration membrane is not well protected and the impurity filtration effect is not ideal, the water flow becomes smaller, and the filtration water flow can only reach 1 ton of water. left and right, and the removal effect of organic matter such as chloride ions in tap water is not good

Embodiment Construction

[0015] Now illustrate the present invention in conjunction with accompanying drawing and embodiment.

[0016] Such as figure 1 , 2 The one-piece composite double-membrane filter element shown is composed of a carbon fiber membrane cover body 3 with a closed end, an ultrafiltration membrane shell 2 with an ultrafiltration material 1 installed therein, and a 4-layer non-woven fabric. The ultrafiltrate is a thin strip of PE ultrafiltrate. The ultrafiltration membrane casing 2 is sheathed in the carbon fiber membrane cover body 3 , and the non-woven fabric layer 4 is wrapped on the outer peripheral wall of the carbon fiber membrane cover body 3 .

[0017] Such as image 3 The ultrafiltration membrane casing 2 shown has an arc surface at its top, and filtering through holes 21 and 22 are respectively provided on the arc surface and the bottom surface. The outer peripheral wall at the bottom of the ultrafiltration membrane housing can be provided with an elastic sealing ring 5 ....

Abstract

The invention discloses an integrated composite double-membrane filter element. The integrated composite double-membrane filter element mainly comprises a carbon fibre membrane cover body and an ultra-filtration membrane shell in which a polyethylene (PE) ultra-filtration object is arranged, wherein the ultra-filtration membrane shell is sleeved in the carbon fibre membrane cover body; a non-woven fabric layer is coated on a peripheral wall of the carbon fibre membrane cover body; filtration through holes are formed on upper and lower end faces of the ultra-filtration membrane shell respectively; and the top end of the carbon fibre membrane cover body is a closed end. In the invention, a single external pressure ultra-filtration membrane in the prior art is eliminated; non-woven fabrics adopted by the filter element can filter visible large-particle impurities such as sediment and rust so as to well protect a carbon fibre membrane; the carbon fibre membrane can filter organic matters from water such as chloride ions and benzene; and a PE ultra-filtration membrane has better effects of removing harmful substances such as bacterial viruses of colloids of suspended matters and heavy metal and remaining mineral substances which are beneficial to a human body. An experiment result shows that: the water penetration capacity of the filter element can be equal to 4 tons of water; filtration accuracy is equal to 0.01 microns; and the water penetration capacity is quite stable.

Description

technical field [0001] The invention relates to a water purification device. Background technique [0002] With the improvement of people's living standards and the strengthening of health awareness, drinking healthy and pure water has penetrated into people's daily life. At present, most of the faucet water purifier filter elements used by people use a single external pressure ultrafiltration membrane. Since the ultrafiltration membrane is not well protected and the impurity filtration effect is not ideal, the water flow becomes smaller, and the filtration water flow can only reach 1 ton of water. left and right, and the removal effect of organic matter such as chloride ions in tap water is not good. Contents of the invention [0003] Aiming at the defects in the prior art, the invention provides an integrated composite double-membrane filter element with stable water flow. The filter element can effectively improve the removal effect of chloride ion organic matter, and...
