Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a novel water purification device. Background Art

[0002] Since reverse osmosis membrane or nanofiltration membrane has a high filtration accuracy, it can effectively remove various toxic and harmful pollutants such as fine particles, organic matter, soluble salts, heavy metal ions, bacteria, viruses and other microorganisms, pesticide residues, etc. in water. At present, water purifiers using reverse osmosis membrane or nanofiltration have been widely used, especially for households to further treat tap water. However, ordinary reverse osmosis pure water machines or nanofiltration water purifiers have the following shortcomings and defects during use:

[0003] (1) The wastewater ratio is relatively high and water is not saved. According to the permeation characteristics of the reverse osmosis membrane, in order to avoid excessive salt concentration on the membrane surface causing concentration polarization, the recovery rate of the reverse osmosis membrane must be strictly controlled. Generally, the recovery rate of a single reverse osmosis membrane element should be controlled below 15%, so that 85% of the water is discharged in the form of concentrated water. The wastewater ratio of a general household reverse osmosis membrane is 3:1, or even as high as 5:1, that is, to produce 1 cup of pure water, 3 to 5 cups of wastewater are produced. Moreover, with the development of membrane pollution, the water production flux of the membrane gradually decreases and the wastewater ratio gradually increases. If these "wastewaters" are not utilized, it will cause a great waste of water resources. Therefore, improving the recovery rate of reverse osmosis pure water machines is a difficult problem that needs to be solved at present. Common solutions include: ①, forcibly reducing the amount of concentrated water, or using dead-end filtration pulse cleaning, etc. This method will inevitably shorten the life of the reverse osmosis membrane and affect the water quality of the effluent. ②, recycling wastewater, returning concentrated water to the water inlet pipe, or injecting it into the tap water pipe. For example, patent CN201737789U, this method also causes concentrated water to circulate in the RO machine and cannot be discharged. Injecting it into the tap water pipe cannot ensure that the water purifier can use the tap for domestic use while making water. Therefore, this type of method cannot fundamentally solve the problem. Therefore, the generation of wastewater from the reverse osmosis water purifier is inevitable, and it is basically impossible to achieve zero wastewater discharge. We can only take measures to reduce the amount of wastewater.

[0004] Moreover, after the existing water purification device is installed, it is impossible to effectively realize the direct reuse of waste water. At the same time, the tap where the water purification device is installed cannot realize the direct use of tap water, which brings many inconveniences to actual use.

[0005] Therefore, a novel water purification device is proposed to solve the current shortcomings. Utility Model Content

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is a new water purification device: including a composite filter, a reverse osmosis membrane filter, a delay controller, a booster pump, a water purification faucet and a two-in-one faucet;

[0008] The inlet end of the composite filter is connected to a water inlet pipe, the composite filter is connected to the reverse osmosis membrane filter through a filter water pipe, a booster pump is provided on the filter water pipe, and a water inlet valve is provided between the booster pump on the filter water pipe and the reverse osmosis membrane filter;

[0010] As an improvement, a one-way valve is further included, and the one-way valve is located on the wastewater pipe between the flow sensor and the reverse osmosis membrane filter.

[0011] As an improvement, the filtered water pipe is connected to the raw water pipe through a tee.

[0012] The advantages of the utility model compared with the prior art are:

[0013] 1. By connecting the two-in-one faucet with the raw water pipe and the waste water pipe, the tap water filtered by the composite filter can be directly used, and the waste water generated after being filtered by the reverse osmosis membrane filter can also be used. It can meet the use needs in different situations, and at the same time, it can realize the effective use of waste water and improve the effective utilization rate of water resources;

[0014] 2. By setting up the flow sensor and the delay controller in coordination, the clogging of the reverse osmosis membrane filter under the condition of small wastewater flow can be avoided. By delaying the shutdown of the booster pump, the wastewater can be continuously outflowed for a certain period of time, so as to achieve the flushing of the reverse osmosis membrane filter and effectively extend the service life of the reverse osmosis membrane filter 2;

[0023] Combined with Figure 1As shown, a novel water purification device comprises a composite filter 1, a reverse osmosis membrane filter 2, a delay controller 3, a booster pump 4, a water purification faucet 5 and a two-in-one faucet 6;

[0024] The inlet end of the composite filter 1 is connected to a water inlet pipe 7. During implementation, the water inlet pipe 7 is externally connected to a tap water pipe to enable tap water to enter the water purification device. Through the arrangement of the composite filter 1, the tap water entering the water purification device can be initially filtered, and various particulate impurities in the tap water can be filtered out. At the same time, harmful substances and heavy metals in the tap water can be filtered out to prevent the reverse osmosis membrane filter 2 from being blocked due to excessive alkalinity of the water.

[0025] The composite filter 1 is connected to the reverse osmosis membrane filter 2 through a filter pipe 8. In a specific implementation, the composite filter 1 performs preliminary filtration on the incoming tap water and transports the tap water to the reverse osmosis membrane filter 2 through the filter pipe 8 for secondary filtration. Through double filtration, the water quality is guaranteed.

[0026] Furthermore, a booster pump 4 is provided on the filtered water pipe 8. Through the setting of the booster pump 4, the water passing through the composite filter 1 is transported to the reverse osmosis membrane filter 2, and high-pressure osmosis filtration is performed on the water entering the reverse osmosis membrane filter 2.

[0027] A water inlet valve 9 is provided between the upper booster pump 4 of the filtered water pipe 8 and the reverse osmosis membrane filter 2 . During implementation, the water inlet valve 9 can control the water inlet to the reverse osmosis membrane filter 2 .

[0028] The outlet of the reverse osmosis membrane filter 2 is respectively connected to a clean water pipe 10 and a waste water pipe 11, the clean water pipe 10 is connected to a clean water faucet 5, and the waste water pipe 11 is connected to a two-in-one faucet 6. Specifically, the reverse osmosis membrane filter 2 is provided with a water inlet, a clean water port and a waste water port. In a specific implementation, the water inlet is connected to the filtered water pipe 8 to achieve the entry of water preliminarily filtered by the composite filter 1, the clean water port is connected to the clean water faucet 5 through the clean water pipe 10 to achieve the outflow of clean water after filtration, and the waste water port is connected to the two-in-one faucet 6 through the waste water pipe 11 to achieve the outflow of waste water;

[0029] The clean water pipe 10 is provided with a high-pressure switch 12 electrically connected to the booster pump 4. In actual use, when the clean water faucet 5 is in a closed state, the high-pressure switch 12 controls the booster pump 4 to stop working when a certain pressure is reached in the clean water pipe 10. When the clean water faucet 5 is in an open state, the pressure in the clean water pipe 10 is reduced, thereby controlling the booster pump 4 to work.

[0030] In actual use, the purified water flows out of the purified water faucet 5 after passing through the purified water pipe 10, and the waste water generated by the reverse osmosis membrane filter 2 flows out of the two-in-one faucet 6 after passing through the waste water pipe 11. Therefore, in use, the waste water ratio can be controlled by controlling the opening degree of the two-in-one faucet 6;

[0031] Furthermore, the water filtered by the composite filter 1, even if it is waste water generated after being filtered again by the reverse osmosis membrane filter 2, can meet the requirements of daily water use. At the same time, by setting the two-in-one faucet 6 in the kitchen, bathroom, etc., the waste water generated by the water purification device can be effectively utilized.

[0032] The wastewater pipe 11 is provided with a flow sensor 14. Specifically, the raw water pipe 13 is connected to the end of the wastewater pipe 11. The flow sensor 14 is located on the wastewater pipe 11 between the two-in-one faucet 6 and the connection between the raw water pipe 13 and the wastewater pipe 11, so as to monitor the water flow passing through the wastewater pipe 11.

[0033] Furthermore, it also includes a one-way valve 15 , which is located on the wastewater pipe 11 between the connection between the raw water pipe 13 and the wastewater pipe 11 and the reverse osmosis membrane filter 2 .

[0034] The delay controller 3 is electrically connected to the flow sensor 14 and the booster pump 4 respectively;

[0035] A raw water pipe 13 connected to the two-in-one faucet 6 is connected between the upper booster pump 4 of the filtered water pipe 8 and the composite filter 1 . Specifically, the filtered water pipe 8 is connected to the raw water pipe 13 via a tee 16 .

[0036] In a specific implementation, the two-in-one faucet 6 is simultaneously connected to the raw water pipe 13 and the wastewater pipe 11, so that the tap water filtered by the composite filter 1 and the wastewater filtered by the reverse osmosis membrane filter 2 can be used. At the same time, the one-way valve 15 can be used to prevent tap water from flowing into the water purification device through the wastewater pipe 11.

[0037] In actual use, when the water purification faucet 5 is in a closed state, when the two-in-one faucet 6 is turned on, since the two-in-one faucet 6 is connected to the filtered water pipe 8 through the raw water pipe 13, the two-in-one faucet 6 can directly use the tap water filtered by the composite filter 1, and can also perform preliminary filtration when using the tap water, thereby further improving its water quality;

[0038] When the water purification faucet 5 is turned on, since the pressure in the water purification device is greater than the pressure in the raw water pipe 13, the wastewater in the wastewater pipe 11 can flow out through the two-in-one faucet 6, and the flow sensor 14 detects the water flow through the wastewater pipe 11. When in use, when the flow sensor 14 detects that the water flow through the wastewater pipe 11 is small, the flow sensor 14 transmits the detected flow signal to the delay controller 3. At the same time, when the water purification faucet 5 is closed, the delay controller 3 controls the booster pump 4 to continue running for a certain period of time, so that the wastewater still flows out through the two-in-one faucet 6. The specific outflow time is set by the delay controller 3, so as to achieve the flushing of the reverse osmosis membrane filter 2, which can effectively extend the service life of the reverse osmosis membrane filter 2.

[0039] When in use, it is necessary to first open the two-in-one faucet 6 to allow the tap water filtered by the composite filter 1 to flow out through the raw water pipe 13 and the two-in-one faucet 6. When the water flows through the flow sensor 14, the flow sensor 14 transmits a signal to the delay controller 3. At this time, the delay controller 3 controls the boost pump 4 to work, so that the water purification device starts.

[0040] At the same time, conventional water purifiers are equipped with water inlet solenoid valves, low-pressure switches, high-pressure switches and wastewater backwash wastewater ratio solenoid valves, while this water purification device removes the low-pressure switch and wastewater backwash wastewater ratio solenoid valve, which can effectively reduce the failure rate of the water purifier. At the same time, the wastewater ratio is controlled by a two-in-one faucet, which can greatly extend the service life of the reverse osmosis membrane filter and save water to achieve savings in use costs.

[0041] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
