Ultrafiltration type direct drinking water purifier

Abstract

The invention discloses an ultrafiltration type direct drinking water purifier; and a filtering device comprises a quartz sand filter core, an active carbon filter core and an ultrafiltration filter core, wherein a quartz sand filter core water inlet electromagnetic valve, an active carbon filter core backwash water inlet electromagnetic valve and an ultrafiltration filter core backwash water inlet electromagnetic valve are respectively arranged on pipelines connected with the quartz sand filter core, the active carbon filter core and the ultrafiltration filter core. The ultrafiltration type direct drinking water purifier disclosed by the invention has the advantage of high purifying efficiency and the purified water reaches a drinking standard. The ultrafiltration type direct drinking water purifier disclosed by the invention is convenient to wash, and secondary pollution can be avoided; as a PLC (Programmable Logic Controller) control system is arranged, simplicity and intuitiveness in operation is achieved; and intelligent and efficient water inlet, water outlet and washing pipelines can be achieved.

Description

technical field [0001] The invention relates to a water purification device, in particular to an ultrafiltration type direct drinking water purifier. Background technique [0002] The sanitation and safety of drinking water are directly related to people's health. However, with the development of large industries, the discharge of waste water is increasing day by day, and all the discharged waste water flows into rivers, which directly threatens the tap water with river water as source water. At present, there are many types of water purifiers sold on the market. The main components of the water purifier include water storage tanks, filter devices, water inlet and outlet pipes, etc. Among them, the filter device is the key component of the water purifier, which determines the quality of the water. Purification efficiency and purification quality. At present, the filter devices used in purifiers mostly use activated carbon, quartz stone and reverse osmosis membrane filter e...

AI Technical Summary

Problems solved by technology

At present, the filter devices used in purifiers mostly use activated carbon, quartz stone and reverse osmosis membrane filter elements for filtration. Most of these filter devices have low turbidity removal ability, especially when used alone, the bacterial and microbial indicators of purified water are unqualified and cannot reach Drinking water standards; in addition, water purifiers also have defects such as low filtration efficiency, complex structure of water purification equipment, easy pollution of pipelines, inconvenient disassembly and cleaning, etc.
