Description

Tail water collecting device with self-pressure water outlet and safe water discharge functions for water purifier

Technical Field

The utility model belongs to the technical field of water-saving equipment, and particularly relates to a tail water collecting device of a water purifier.

Background

With the improvement of economic level, people put forth higher requirements on life quality, and are not satisfied with drinking tap water. In view of convenience of water use, more and more households are equipped with water purifiers to further purify municipal tap water into purified water. The water purifier mainly relies on multistage filtration and Reverse Osmosis (RO) to remove various organic matters, inorganic particulate matters, soluble pollutants, microorganisms and other pollutants in water. The reverse osmosis method utilizes the pressure difference between two sides of the RO membrane to force water molecules to permeate the RO membrane from a high-pressure water inlet side to a low-pressure water outlet side, and impurities in the water are intercepted by the RO membrane, so that the aim of purifying the water is fulfilled, and the impurities are discharged along with tail water. Generally, the ratio of RO membrane drainage tail water and purified water of the water purifier is more than 1:1. In order to prolong the service life of the RO membrane, some machines flush the RO membrane with a large amount of water after each water preparation. In the design and installation of the water purifier, in order to prevent water from running out, the tail water is directly discharged into a sewer, so that water resources are wasted. The principle of RO water purification shows that the pollutants in the inlet water are transferred to the tail water, so that the tail water has high impurity content and is not suitable for drinking. However, tap water is primarily filtered and purified by a water purifier before passing through the RO membrane, so that the quality of tail water can still meet the purposes of washing clothes, mopping the floor, watering flowers, flushing and the like.

At present, when a water purifier is installed on an upper door, a manufacturer of the water purifier directly accesses a draft tube into a sewer, and the user is not recommended to change the draft tube by himself. Some users use containers such as a basin and a bucket to access the tail water of the water purifier because of the idea of saving water resources, but the method brings four problems: (1) After the container is fully connected, the container needs to be replaced by manpower, so that the use is inconvenient; (2) If the stored water in the container is not poured out in time, the tail water continuously discharged by the water purifier overflows the container, so that water is drained, and the user needs to take care of the moment; (3) When the tail water pressure is higher, especially when the RO membrane is washed, if the tail water pipe is not fixed and stable, the tail water is easy to fly off to cause serious water leakage; (4) The connection between the draft tube and the sewer is disconnected when the draft tube is connected with water, so that the sewer is easy to cause water and odor reflection, and the indoor environment and the quality of the collected tail water are polluted. The existing tail water collecting device (such as chinese patent CN 215161111U) needs to use a water pump to pump the stored tail water and use an electronic control module to control the tail water, so that the cost is high.

Drawings

FIG. 1 is a schematic diagram of the structural distribution of an embodiment of the present utility model.

Wherein: 10. the device comprises a pressurized tail water storage barrel, an inlet/water intake, a water outlet, a real-time water level in the tail water storage barrel, a safe water discharge water level, a tail water inlet/water intake pipeline, a water intake valve, a water discharge pipeline and an anti-overflow water discharge joint.

Detailed Description

For a better understanding of the present utility model, the present utility model is further described below with reference to the drawings and examples.

As shown in fig. 1, the tail water collecting device of the water purifier having the self-pressurized water discharging and safety water discharging functions is composed of a main body of a pressurized tail water storage tank 10 connected to a tail water outlet of the water purifier through a tail water inlet/outlet pipe 20 and connected to a sewer through a water discharging pipe 30 and an overflow preventing water discharging joint 31. A water intake pipe 22 is connected to the tail water intake/water intake pipe 20, and water can be discharged to an external container through the water intake valve 22.

The tail water inlet/outlet pipeline 20 extends into the bottom of the pressurized tail water storage barrel 10 through the water inlet/outlet 11 at the top of the pressurized tail water storage barrel 10; the drain pipe 30 extends down to the safety drain level 14 through the drain port 12 at the top of the pressurized tail water storage tub 10, which level represents a level corresponding to 67% of the capacity of the tail water storage tub. Accordingly, the forward opening differential pressure of the overflow drain fitting 31 is set to 0.2MPa.

When the water purifier discharges tail water, if the real-time water level 13 in the pressurized tail water storage barrel 10 is lower than the safe water discharge water level 14, the real-time water level 13 rises to compress air above, but the pressure difference between the inside and the outside of the barrel does not reach the forward opening pressure difference (0.2 MPa) of the anti-overflow water discharge joint 31, and the anti-overflow water discharge joint 31 is not opened, so that compressed air in the pressurized tail water storage barrel 10 is reserved. When the real-time water level 13 in the pressurized tail water storage barrel 10 reaches the safe drainage water level 14 (namely, 67% of the volume of the tail water storage barrel is reached), the pressure difference between the inside and the outside of the barrel reaches the forward opening pressure difference (0.2 MPa) of the overflow-proof drainage joint 31, and the excessive tail water is discharged to a sewer through the drainage pipeline 30 and the overflow-proof drainage joint 31, so that the tail water barrel is prevented from overflowing fully, and the pressurized air above the safe drainage water level 14 is remained in the pressurized tail water storage barrel 10.

When water is required to be taken from the pressurized tail water storage barrel 10, the water taking valve 22 is opened, and the stored tail water is extruded through the tail water inlet/outlet pipeline 20 by residual air expansion in the barrel under the action of the air pressure (0.3 MPa) in the pressurized tail water storage barrel 10 and is connected to an external container through the water taking pipeline 21. Sewage and odor in the sewer are not returned under the non-return action of the anti-overflow drain joint 31. If the tail water is discharged by the water purifier and the water is taken, the water taking valve 22 can be directly opened without affecting the work of other parts.

When the water purifier does not discharge tail water and does not need to take water from the pressurized tail water storage barrel 10, the pressure inside the pressurized tail water storage barrel 10 is maintained for the next water taking because the pressure difference between the inside and the outside of the pressurized tail water storage barrel 10 does not exceed the forward opening pressure difference of the anti-overflow water discharging joint 31: the non-return action of the anti-overflow drain joint 31 prevents the reverse overflow of sewage and odor in the sewer, and ensures the indoor environmental sanitation and the good water quality in the pressurized tail water storage barrel 10.
