A reverse osmosis pure water machine with concentrated water regulating controller

Abstract

The invention provides a reverse osmosis water purifier with a concentrated water regulating controller and belongs to the technical field of water production. The reverse osmosis water purifier is used for solving the problems of water resource waste and the like because the water producing speed of the existing reverse osmosis water purifier is gradually reduced. The reverse osmosis water purifier with the concentrated water regulating controller comprises a reverse osmosis membrane filter and a water storage pressure barrel; the regulating controller comprises a main body; the main body is provided with a concentrated water inlet, a concentrated water outlet and a purified water inlet, which are communicated with each other; a tapered water feeding hole is formed between the concentrated water inlet and the concentrated water outlet; a movable slider is arranged in the purified water inlet; an ejector pin is arranged at one end of the slider; an adjusting cap is fixedly connected to the end portion of the purified water inlet in a threaded sealing manner; a spring sleeves the slider; one end of the spring props against the main body, while the other end of the spring props against the slider; when the slider moves away from the adjusting cap, the ejector pin gradually goes deep into the water feeding hole to reduce the flow area of the water feeding hole. The reverse osmosis water purifier has the advantages of high water producing speed and reduction of water resource waste.

Description

technical field [0001] The invention belongs to the technical field of water production, and relates to a reverse osmosis pure water machine, in particular to a reverse osmosis pure water machine with a concentrated water regulating controller. Background technique [0002] The reverse osmosis pure water machine is a device that integrates microfiltration, adsorption, ultrafiltration, reverse osmosis, ultraviolet sterilization, ultra-purification and other technologies to directly convert tap water into ultra-pure water, which can be directly drunk after conversion. [0003] The reverse osmosis pure water machine is a relatively mature pure water manufacturing technology. The existing reverse osmosis pure water machine, for example, the Chinese patent literature discloses the reverse osmosis pure water machine [application number: 201120070355.X; authorized announcement number: CN201952301U ], which in turn includes the connected PP cotton filter, granular activated carbon f...

Problems solved by technology

However, the reverse osmosis pure water machine with this structure, the water production speed of the pure water machine is relatively slow, so a water storage pressure tank is configured in the water production system to store the prepared pure water, making it necessary to use It can provide more pure water at one time, but because of the existence of the water storage pressure tank, it is equivalent to setting a system back pressure at the pure water end of the reverse osmosis filter, so that the reverse osmosis pure water machine During water production, the pressure difference before and after the membrane of the reverse osmosis filter gradually decreases, resulting in a gradual slowdown of the production speed of pure water, that is, the reduction of pure water production per unit time, and because the water supply speed of the booster pump is basically the same , which increases the proportion of concentrated water at the wastewater end of the reverse osmosis pure water machine, that is, more water is discharged as concentrated water, resulting in a serious waste of water resources
