Description

Water-saving water purifier

Technical Field

The utility model belongs to the technical field of water purification unit, especially, relate to a water conservation water purifier.

Background

The water purifier is also called water purifier and water filter, the technical core is a filtering membrane in a filter element device, the water purifier mainly adopts two technologies of an ultrafiltration membrane and an RO reverse osmosis membrane, and the water purifier is small water treatment equipment for deeply purifying water according to the use requirement of water. Water purifiers can be classified into various types according to different purification principles and processes. The RO reverse osmosis technology has the highest filtration precision (the filtration precision is 0.0001 micron), and the reverse osmosis membrane only allows water molecules and dissolved oxygen to pass through as the aperture of the reverse osmosis membrane is only one hundred thousand times of the diameter of hair, so that all impurities in water, such as pesticides, bacteria, viruses, heavy metals and other harmful substances, are almost completely intercepted and removed. There are many other filtration techniques besides reverse osmosis: nanofiltration (with filtration precision of 0.001-0.0001 micrometer), ultrafiltration membrane (with filtration precision of 0.1-0.01 micrometer), and fine filtration (with filtration precision of below 0.1 micrometer, such as ceramic filtration and PP cotton filtration).

At present, the water purifier mainly adopts a direct backflow method, wastewater directly flows back to the front end to be filtered again, however, compared with a water purifier directly discharging wastewater, the conductivity of purified water of the backflow water purifier is high, the pollution degree is increased, the water quality of the backflow water purifier cannot reach the standard, and water cannot be drunk directly. Therefore, improvements are needed.

Disclosure of Invention

The utility model aims at providing a water-saving water purifier aiming at the defects existing in the prior art.

The utility model adopts the technical proposal that: a water-saving water purifier comprises a pressure release valve, a filter element group, a booster pump, an RO membrane, a t33 filter element and a water outlet tap which are sequentially communicated through a pipeline; a softening filter element is connected on a pipeline between the pressure release valve and the filter element group; be connected with back flow one between the waste water outlet end of pipeline between relief valve and the softening filter core and the RO membrane, be connected with check valve one on the back flow one, be connected with waste water drain pipe and the back flow two of the pipeline intercommunication of being connected with the booster pump end of intaking on the back flow one between check valve one and the RO membrane outlet end, be connected with waste water on the waste water drain pipe and compare, proportional throttle valve and check valve two have been connected gradually along the rivers direction on the back flow two.

The filter element group comprises a PP filter element, a UDF filter element and a CTO filter element which are sequentially communicated with the pipeline.

And a third one-way valve is connected on a pipeline between the RO membrane and the t33 filter element.

The proportional throttle valve is 1/4 proportional throttle valve.

The flow rate of the wastewater ratio is 50-100 ml/min.

After the structure is adopted, compared with the prior art, the utility model the advantage that has is:

1. the softening filter element can remove water alkali and improve water quality;

2. connecting a wastewater discharge pipe with a wastewater ratio of 50-100 ml/min to enable part of wastewater to form backflow, and enabling the part of wastewater to flow back to the front ends of the filter element group and the softening filter element for re-filtering;

3. one part of waste water that RO membrane waste water play water end came out gets back to RO membrane import department through 1/4 proportion choke valve, and one part gets back to the front end of filter element group and softening filter core and filters again, so circulation is reciprocal, reaches the effect of water conservation for the pure water ratio reaches 3: 1.
