The reverse osmosis water purifier is a water purifying device commonly used at present, and generates a large amount of waste water while purifying water quality to generate pure water. Therefore, the high recovery rate and low wastewater of the reverse osmosis water purifier are always the development direction of the whole water purification industry.

In order to achieve the purpose of water saving, some reverse osmosis water purifiers increase the recovery rate by enlarging the membrane area, which can lead to the obvious increase of the cost of wastewater recovery equipment. Another serious problem is that it easily causes clogging of waste valves of waste water reclamation facilities. And a part of reverse osmosis water purifiers are used for modifying a waste water pipeline, so that the waste water is mixed with tap water and then enters the reverse osmosis membrane filter element again for filtering. However, when the Total Dissolved Solids (TDS) concentration in the mixed water exceeds the requirement of the reverse osmosis membrane filter element on the quality of the inlet water, the service life of the reverse osmosis membrane filter element is greatly shortened. The cost of the reverse osmosis membrane filter element is high, and the method has a water-saving effect but cannot be paid.

Therefore, most reverse osmosis water purifiers in the market directly discharge the generated wastewater, which causes serious waste of water resources.

The utility model provides a waste water recovery equipment and clean system who has this waste water recovery equipment. In order to understand the principles of the present invention as a whole, the purification system will first be described. As shown in fig. 1, the water purification system 10 includes a filtering apparatus 100 and a wastewater reclamation apparatus 200. The filter device 100 may be a reverse osmosis filter device having a reverse osmosis membrane cartridge disposed therein. The reverse osmosis membrane filter element produces pure water and waste water in a certain proportion. Thus, the filter device 100 comprises a water inlet a, a pure water outlet B and a waste water outlet C. The water inlet A is communicated to a tap water pipeline 300. After the tap water enters the filtering device 100, the pure water generated by filtering flows out through the pure water outlet B, and simultaneously, the wastewater generated according to a certain proportion flows out from the wastewater outlet C.

The application provides a waste water recovery equipment 200 can retrieve and carry the lower scene of requirement to water quality to the waste water that waste water export C flows and recycle to reach the purpose of water conservation. The wastewater reclamation apparatus 200 is not limited to recycling only wastewater generated by the reverse osmosis filtration device, and the reverse osmosis filtration device 200 may be applied in any situation where it is desired to recycle and reuse wastewater. The recovered waste water can be used as toilet flushing water, greening water, ground cleaning water, field water and the like.

The wastewater reclamation apparatus 200 applied to the filter device 100 will be described in detail below. As shown in fig. 1, the wastewater reclamation apparatus 200 includes a water storage tank 210 and a waterway device 220.

The water storage container 210 serves to recover and temporarily store the wastewater generated from the filtering apparatus 100. The water storage container 210 has a waste water inlet 202 and a first water outlet 204. The waste water inlet 202 is communicated to the waste water outlet C of the filter device 100. Wastewater discharged from the filtering apparatus 100 enters the water storage tank 210 through the wastewater inlet 202. The wastewater inlet 202 is generally disposed at a position close to the wastewater outlet C of the filter device 100. The first water outlet 204 is generally disposed at the bottom of the water storage container 210 so as to drain the waste water in the water storage container 210.

The waterway device 220 is connected to the water storage container 210, and specifically, the waterway device 220 is connected to the first water outlet 204 of the water storage container 210, and is used for delivering the wastewater in the water storage container 210 to one or more water using ends when needed. Illustratively, the water service end may include a waste faucet 410, a toilet 420, and other water service ends 430, as shown in FIG. 1. In life, water can be directly received from the waste water faucet 410 for washing the ground, watering flowers, washing cars, and the like. Other water ends 430 may include, for example, high pressure water guns through which plants may be directly watered or carwashed.

As shown in fig. 2, the waterway apparatus 220 may include a waste water pipe 232, a first valve body 222, and a pressurizing pump 224. The waste pipe 232 has a water inlet end 232a connected to the first water outlet 204 and a water outlet end 232b connected to the second water outlet 206. The second water outlet 206 may be connected to one or more of the above-mentioned water usage ports. The first valve body 222 and the pressurizing pump 224 are sequentially provided on the waste water line 232. The first valve body 222 is closer to the first water outlet port 204 than the booster pump 224. The first valve body 222 controls the connection and disconnection of the waste pipe 232. The first valve body 222 may be a manual control valve or an electric control valve. Preferably, the first valve body 222 may be a solenoid valve. The electromagnetic valve has the advantages of simple structure, high reliability, small quantity, light weight and lower cost. A booster pump 224 is used to pressurize the wastewater in the wastewater line 232 to deliver the wastewater to one or more water users. The booster pump 224 may be activated when the first valve body 222 is opened. In the case where the first valve body 222 is an electrically controlled valve, the booster pump 224 may be electrically connected in series with the first valve body 222 to a power source to couple the two.

The utility model discloses a with waste water recovery to water container 210 in to carry the waste water in water container 210 to one or more water end through waterway device 220 when needs, improve filter equipment 100's rate of recovery indirectly, and then can solve the water conservation problem in the water resource deficient area.

The above-described start-up of the booster pump 224 needs to be manually operated. For example, in embodiments where the booster pump 224 is electrically connected to the power source in series with the first valve body 222, the circuit needs to be completed manually, which may require a manual switch. However, the manual switch requires the user to manually close the booster pump 224 and the first valve 222 before the user uses water, and then to take water from the water using end. Thus, some inconvenience may be brought to the user.

Accordingly, in a preferred embodiment, the waterway apparatus 200 may further include a high-pressure switch 240. The high voltage switch 240 is capable of automatically closing when a user draws water and automatically opening when no water is drawn. The user only needs to operate the valve at the water end, so the use is very convenient. A high pressure switch 240 is located on the line 234 between the waste line 232 and the second outlet 206. The booster pump 224 may be electrically connected in series with the high voltage switch 240. The booster pump 224 operates when the high voltage switch 240 is closed. The high-voltage switch 240 has a preset pressure value, when the pressure in the pipeline reaches the preset pressure value, the pipeline is in a full water state, and the high-voltage switch 240 is switched off, so that the booster pump 224 is stopped, and the whole equipment is ensured to enter a standby state after being full of water. When a user takes water from the water using end, the water pressure at the second water outlet 206 end is reduced, when the water pressure is lower than the preset pressure value of the high-pressure switch 240, the high-pressure switch 240 is automatically closed, the booster pump 224 is electrified, the booster pump 224 starts to take water from the water storage container 210, and the water is continuously conveyed to the water using end. When the user finishes taking water and closes the valve at the water using end, the booster pump 224 continues to pump water to the high-pressure switch 240, and once the water pressure at the high-pressure switch 240 reaches a preset pressure value, the high-pressure switch 240 is automatically switched off. The high-voltage switch 240 is turned off, and the booster pump 224 stops operating, i.e., pumping water. The whole wastewater reclamation apparatus 200 is in a standby state.

The water storage capacity of the water storage container 210 is limited, and if the water intake amount at the water using end is large, the water is likely to be cut off during the water intake. Based on this, the waterway device 220 may further include a water replenishing pipeline 236. The inlet end 236a of the refill line 236 is adapted for communication to a refill water source. The refill water source may be, for example, a tap water conduit 300. When multiple wastewater-producing devices are included in the same application scenario, the source of refill water may also be one or more of these devices. The water outlet end 236b of the water replenishing pipe 236 is communicated to the water outlet end 232b of the waste pipe 232. Thus, when water can no longer be taken from the water storage container 210, water can be taken from the refill water source via the refill pipe 236. If necessary, the waste line 232 and the make-up line 236 may simultaneously deliver water to the second outlet 206. The water replenishing pipe 236 is provided with a second valve body 226. The second valve body 226 controls the make-up and break-out of the refill line 236. The second valve body 226 may be a manual control valve or an electric control valve. Preferably, the second valve body 226 may be a solenoid valve.

When the high pressure switch 240 is provided, one end of the conduit 234 where the high pressure switch 240 is located is connected to the water outlet end 236b of the water replenishing conduit 236 and the water outlet end 236b of the water replenishing conduit 236, and the other end is still connected to the second water outlet 206.

Further, in order to avoid the water level in the water storage container 210 from reaching the pumping requirement of the booster pump 224 and causing the booster pump 224 to run idle, a water level switch 250 may be preferably provided. The water level switch 250 is used for detecting the water level in the water storage container 210 and automatically controlling the on-off of the circuit according to the water level. The water level switch 250 is used for controlling the on-off of the circuit according to the water level condition of the water storage container 210. The water level switch 250 is turned off when the water level in the water storage container 210 is lower than a preset lower limit. The booster pump 224 stops operating when the water level switch 250 is turned off. The water level switch 250 may include one or more of a capacitive water level switch, an electronic water level switch, an electrode water level switch, a photoelectric water level switch, a tuning fork water level switch, a floating ball water level switch, and the like. The water level switch 250 may also be an intelligent water level controller. The water level switch 250 is electrically connected to the booster pump 224. The water level switch 250 may be electrically connected in series with the booster pump 224.

A check valve 228 is provided in the waste water line 232 between the booster pump 224 and the first valve body 222. The check valve 228 prevents the waste water from flowing back to prevent the booster pump 224 from reversing.

Fig. 3 shows a circuit diagram of a wastewater reclamation apparatus of an exemplary embodiment. As shown in fig. 3, the first valve body 222 is a waterway normally closed solenoid valve. The waterway normally closed electromagnetic valve is an electromagnetic valve which is switched on after being electrified. The pressurizing pump 224, the first valve body 222, the high-pressure switch 240, and the water level switch 250 are electrically connected to a power source in series. In the series circuit, the on-off of the circuit is controlled by the high-voltage switch 240 and the water level switch 250, that is, when both are connected at the same time, the current in the booster pump 224 passes through, and the booster pump 224 starts to work. In the illustrated embodiment, the power supply is capable of providing 24V dc power. In other embodiments, different types of power supplies may be selected depending on the type and model of electrical components in the circuit.

When the water level switch 250 senses that the water level in the water storage container 210 is higher than or equal to the preset lower limit, it is in a closed state. At this time, if the user takes water from the water end, the line between the high voltage switch 240 and the water end is depressurized. When the water pressure drops below the preset pressure value of the high pressure switch 240, the high pressure switch 240 closes. When the water level switch 250 and the high-pressure switch 240 are simultaneously closed, the first valve body 222 is energized, the waste water pipe 232 is connected, and the booster pump 224 is also energized, so that the booster pump 224 starts to operate to pump water to the water using end.

When the water level switch 250 senses that the water level in the water storage container 210 is lower than the preset lower limit, it is in an off state. At this time, the booster pump 224 cannot be energized regardless of the state of the high-voltage switch 240.

It follows that the wastewater reclamation apparatus 200 is only consuming power when a user is taking water.

Preferably, the second valve body 226 is a waterway normally open solenoid valve. The waterway normally open electromagnetic valve is an electromagnetic valve which is switched off after the waterway is switched on. The second valve body 226 is electrically connected in parallel with the booster pump 224, the first valve body 222, and the high-pressure switch 240.

When the water level switch 250 senses that the water level in the water storage container 210 is higher than or equal to the preset lower limit, the water level switch 250 is in a closed state. The second valve body 226 is energized and the second valve body 226 controls the water replenishing line 236 to be disconnected. The water use end can only take water from the waste line 232.

When the water level switch 250 senses that the water level in the water storage container 210 is lower than the preset lower limit, it is in an off state. The second valve body 226 is de-energized. The second valve 226 controls the water supply pipeline 236 to be connected, and when the user takes water from the water using end, the water supply pipeline 236 is responsible for supplying water. At this time, the wastewater reclamation apparatus 200 does not consume electricity.

In an exemplary embodiment, the lower portion of the water storage container 210 is provided with a recess 260 and a cover 270 covering the recess 260, as shown in fig. 2. The waterway device is disposed in the recess 260, and the second water outlet 206 is disposed on the cover 270. When the water replenishing pipe 236 is provided, the water inlet end 236a of the water replenishing pipe 236 may also be provided on the cover 270. In this manner, the wastewater reclamation apparatus 200 is provided as a compact, integrated structure. Moreover, the overall shape formed by the container wall of the water container 210 and the cover 270 may have a certain shape, such as a cylindrical shape or a rectangular parallelepiped shape, so as to save the occupied space; or may also have a shape designed from an aesthetic point of view.

In order to prevent the waste water generated by the filtering apparatus 100 from being discharged into the water storage container 210 after the waste water fills the water storage container 210, it is preferable that an overflow 208 is provided at the top of the water storage container 210. The overflow 208 may be connected to the sewer conduit 400, as shown in figure 1, so as not to interfere with the normal operation of the filter apparatus 100.
