Composite filter element ultrafiltration water purifier

Abstract

The invention discloses a composite filter element ultrafiltration water purifier. The water purifier comprises a tank body, a connecting bottom plate and a top faucet, the connecting bottom plate andthe top faucet are an integrated structure, the top faucet is arranged at the middle of the upper end surface of the connecting bottom plate, the lower end of the connecting bottom plate is in threaded connection with the upper end part of the tank body and is fixed to the top surface of the tank body by locking bolts, a composite filter element is arranged in the tank body, the inner sidewall ofthe tank body and the outer sidewall of the composite filter element form an inner cavity for accommodating impurities, a sealing ring in sealing connection with the connecting bottom plate is arranged at the inner bottom end of the top faucet, a stainless steel filter screen ring is arranged at the middle of the sealing ring, a PP cotton filter disc is arranged in the top faucet above the sealing ring, and a water filter disc is arranged above the PP cotton filter disc. The composite filter ultrafiltration water purifier allows raw water to be preliminarily filtered and then filtered by thecomposite filter element, so the service life of the composite filter element is prolonged, and the composite filter element is convenient to disassemble and maintain structurally.

Description

technical field [0001] The invention belongs to the technical field of water purification equipment, and in particular relates to a composite filter element ultrafiltration water purifier. Background technique [0002] Most of the water bodies in the world are seriously polluted, exacerbating the contradiction of water shortage. Traditional tap water treatment methods can no longer guarantee high-quality drinking water, and there are still two pollution problems in municipal water supply, such as water supply from high-rise water tanks and long tap water pipelines, which will cause potential rust, scale and Therefore, various water purifiers have emerged at the historic moment, and the filtration methods and filter materials used by various water purifiers are also different. Water purifiers are related to the drinking water safety and health of millions of people. For this reason, the water quality of water purifiers must be paid attention to, and the quality of water puri...

Problems solved by technology

[0003] The existing composite filter element ultrafiltration water purifier performs ultrafiltration on the raw water through the composite filter element during use. Although the purity of the raw water is improved, the large particles of impurities in the raw water are easy to cause damage to the composite filter element, reducing the use of the composite filter element. life, and the overall structure is not easy to disassemble, resulting in inconvenience of maintenance and testing
