Description

Membrane-pump integrated supercharged water purifying device and system and implementation method

Technical Field

The invention relates to an RO reverse osmosis water purification device, a system and a method thereof, in particular to an improvement of a reverse osmosis membrane pump integrated hydraulic drive double-pressurization water purification device, a system and an application implementation method.

Background

In the prior art, reverse Osmosis is also called reverse Osmosis (abbreviated as RO), which is a membrane separation technology, and filtration is performed by using pressure difference as a driving force. "osmosis" is a physical phenomenon in which reverse osmosis is a process of applying a pressure higher than that of natural osmosis to water containing salts and various fine impurities (i.e., raw water) to cause the water to reverse-permeate from a side having a high concentration to a side having a low concentration, thereby achieving a filtration and purification function.

The reverse Osmosis membrane (Revers Osmosis Film) can intercept various inorganic ions, colloidal substances and macromolecular solutes in water so as to obtain purified pure water, and most of bacteria, germs, fine impurities, organic matters, heavy metals, other harmful substances and the like in raw water can be discharged through a waste water outlet. The reverse osmosis process is simple, and the reverse osmosis is rapidly developed in recent 20 years, so that the reverse osmosis membrane is widely applied to pure water preparation and household direct drinking machines.

As shown in fig. 1, the household reverse osmosis water purification system 60 in the market in the prior art is also called a water purifier and an RO machine, and is a water purification apparatus using a reverse osmosis membrane with a filtration pore size of 0.0001 micron as a main filtration element, which generally receives a city water supply source 01, and is filtered by a water purification assembly 02 composed of an electric pump and a reverse osmosis membrane to a water storage tank 03, and finally supplied to a drinker; because the porosity of the permeable membrane reaches the nanometer level, a great pressure drop is caused when water passes through the membrane in the water making process. Therefore, when the pressure of city tap water is low, the final pressure of pure water passing through the reverse osmosis membrane is too low to be filled into the water storage barrel, and the working efficiency is also seriously reduced, so that a certain pressure must be applied to water to increase the pure water output pressure when the tap water is filtered through the reverse osmosis membrane, and therefore, a water pump is needed and power is needed, so that the structure of the equipment is complex, and the electrical safety problem is worried about by using electrical equipment.

The domestic RO water purification machine of prior art will generally install the booster pump additional, and its main objective is in order to increase water pressure when running water pressure is lower, increase the requirement of pure water delivery pressure when increasing reverse osmosis membrane filtration in order to satisfy. In general, the water pressure of tap water is 1.8kgf/cm²In time, the normal operation of the water production work of the household RO water purifier can be basically met, and the water pressure of most urban tap water is known to be about 2kg, so the water can normally work. However, the water pressure of city tap water is not stable, and the water pressure of city water is different due to different floor positions of users, and the RO water purifier product with the pump is not adjusted according to the change conditions, and the water pressure may be adjusted at 2kgf/cm even if the water pressure is changed²The electric pump is still started to be pressurized again under the condition of the pressure, so that not only can electric power resources be wasted for a long time, but also the water pressure is easily overhigh for a long time, the failure rate of an electric appliance control element and the pipe-disconnecting and water-leaking probability are increased, and the electric pump RO water purifier system is a fatal defect in the design of the conventional electric pump RO water purifier system equipment and is also a place where failures often occur.

Generally, in the conventional process, the RO water purification machine which increases the water pressure by the electric pump is adopted, and the system is required to be matched with electric control elements such as a power adapter, a power supply, a transformer, the electric pump, a low-pressure valve, a high-pressure valve, an electromagnetic valve, a flushing valve, an MCU circuit controller and the like to control the on-off operation of a water path and a circuit. Therefore, the RO water purification machine with the electric pump has not only a water path but also a circuit system, a complex system control structure, many joints and a high failure rate, and the system cannot normally operate due to the failure of the electrical components, for example: the problems of stopping water production, stopping wastewater flow, leaking water and the like exist, the product quality is very unstable, the after-sale maintenance frequency and the service cost are greatly increased, the damage to consumers is easily caused, and the problems always bother manufacturers, terminal sellers and wide users.

In addition, the conventional RO water purification machine with the electric pump needs to be provided with a whole set of electric appliance control elements, so the material cost is high, the links such as production material preparation, final assembly production, performance detection and the like are complicated, the production efficiency is low, more manpower needs to be added, the labor cost is high, and the industrial ecology restricts the product order supply and distribution flow and the market competitiveness.

In the market, a household RO reverse osmosis water purification machine system with an electric pump generates waste water (concentrated water) in operation, the pressure of a pure water storage barrel in the water production process is gradually increased, the back pressure is increased, the pure water output of a reverse osmosis membrane is reduced, the waste water discharge capacity is increased, the common proportion is more than 1:3, namely, more than three cups of waste water need to be discharged when one cup of pure water is produced, the serious waste of water resources is caused, and the system is not in accordance with economic benefits and energy-saving and environment-friendly policies.

Because the current water source is seriously polluted, the RO reverse osmosis water purifier is widely used in places such as units, factories, laboratories, offices, schools, families, bars, coffee shops, markets and the like as safe drinking water equipment and generally enters the lives of people. Therefore, there is an urgent need in the market for a non-electric RO water purifier technology that does not require electric power and does not use electric control elements, thereby completely avoiding electronic component failures, greatly improving product quality stability, and reducing after-sale maintenance and service costs, thereby eliminating the concern of electrical safety problems and reforming the fatal defects of the design of the RO water purifier products in the system devices for a long time.

Accordingly, the prior art is yet to be improved and developed.

The invention is characterized in that a slot 13 for inserting an RO reverse osmosis membrane filter element 22 is arranged at the tail end, namely below the front-section water making chamber 20 in a shell 10, a first pure water outlet 17 is arranged in the slot 13, the center of the whole RO filter element 22 is a pure water channel, the chamber between the outer side of the RO filter element 22 and the shell 10 is a channel for water to be filtered, the water to be filtered is introduced from a water outlet 54 on a U-shaped plastic piece 51, and part of water is filtered by the RO reverse osmosis membrane filter element 22 to form pure water which is output from the first pure water outlet 17; the inner side edges of the upper side and the lower side of the shell are provided with a first waste water outlet 15, and waste water after filtration treatment penetrates through the shell 10 from the first waste water outlet 15 and is led to the outside of the water making cabin at the front section of the cabin. A quick connector 16 is arranged in communication with the first waste water outlet 15, and an adjustable flow control valve 12 can be arranged in communication with the first waste water outlet or directly connected with an accessory for controlling the throttling waste water ratio.

As shown in FIG. 4a and FIG. 4b, the elastic coefficient of the first spring 52 is preset and selected to limit the inflow pressure of the water source 59 to 1.2-1.4 kgf/cm²The size of the shut-off boosting mode is automatically started within the range. When the flowing pressure of the inlet water is 1.2 to 1.4kgf/cm²Under the condition of ultra-low pressure in the range, at the moment, the elastic force of the first spring 52 props up the cut-off valve plate 53 to enable the cut-off valve plate 53 to be higher than the three water outlets 54 on the side surface of the U-shaped plastic part 51, so that the water flow of the water source 59 is intercepted (under the condition of high water pressure, the pressure of the water flow presses the first spring 52 through the cut-off valve plate 53 to enable the cut-off valve plate 53 to be kept at the position lower than the three water outlets 54, at the moment, the low-pressure cut-off booster mechanism 50 does not work), the water source 59 is rapidly in a gradually boosted state in the upper cavity 56 of the U-shaped plastic part 51 after being intercepted and stopped, and the cut-off valve plate 53 is acted by the accumulated; meanwhile, pure water and wastewater in the front and rear cabin are continuously discharged and are in a low-pressure state, and the pressure through hole 55 is communicated with the water making cabin 20, so that the lower cavity 57 is also in a low-pressure state, and the flow-stopping valve plate 53 is favorably descended in the flow-stopping process.

When the upper chamber 56 is filled with water to be filtered from the water source 59, the water is pressurized up to 1.5kgf/cm²When the water is discharged from the water outlet 54, the water in the upper chamber 56 is pressurized, the pressurized water is rapidly discharged from the water outlet 54 into the outer chamber of the RO reverse osmosis membrane filter element 22, and simultaneously the pressure in the upper chamber 56 of the U-shaped plastic member 51 is instantaneously reduced, so that the water flows into the water production chamber. Because the lower chamber 57 is communicated with the water making chamber through the pressure through hole 55, the pressure in the lower chamber 57 is rapidly increased, the elastic force restoring force of the first spring 52 also acts together, and the cut-off valve plate can be heightened again53 above said water outlet 54, to start intercepting the water flow of the water source 59 again.

The water is repeatedly circulated, and the water inlet pressure can be increased by using the mechanism of intercepting the water source 59 and delaying the discharge, so as to keep the water source 59 constant at not less than 1.5kgf/cm²The pressure of the water enters the water making chamber, so that the RO reverse osmosis water purifier can keep efficient production of pure water and reduce discharge of waste water. Moreover, the structure completely adopts a mechanical structure, does not need to use electrical equipment, and has the advantages of simple structure, long service life and safety.

The low pressure shut-off and pressure boost mechanism 50 of the invention is used when the flowing water pressure of the water source 59 is more than 1.5kgf/cm²When the pressure is higher than the preset value, the interception valve plate 53 is constantly positioned at a position lower than the water outlet 54 on the side surface of the U-shaped plastic part 51 due to the pressure of water flow, and the low-pressure interception supercharging organ 50 is in a non-interception supercharging action state; when the flowing water pressure of the water source 59 is less than 1.1kgf/cm²When the water source is closed, the water source enters the water making cabin from the water source 59, the interception pressurization is ineffective, and the interception valve plate 53 is constantly positioned at a position higher than the water outlet 54 on the side surface of the U-shaped plastic part 51; only the water source 59 flows water with the pressure of 1.2 to 1.4kgf/cm²The time plays a role, and certainly under the condition of the same working principle and structure of the invention, the working range can be modified by setting and modifying the parameters of the spring and the interception valve plate, even if the working range is the same, the frequency of delayed discharge is different by the interception water source 59 due to different specific parameters and different external water supply pressures. However, the low-pressure intercepting and pressurizing mechanism 50 of the present invention can automatically select and match its own working water pressure, and has excellent technical effects.

The diameter that sets up waste water entry 24 is greater than second waste water export 27, and the pressure in waste water chamber 33 just is greater than pure water chamber 32 like this, and the water pressure of second pure water export 28 is less than the water pressure of second waste water export 27 promptly, can promote silica gel diaphragm 31 by waste water to move to pure water chamber 32 according to the pressure differential principle to increase pure water output pressure, through silica gel diaphragm 31 extrusion, cooperate umbrella-type silica gel check valve, pour into the water storage bucket through second pure water export 28 with the pure water of increased pressure.

The hydraulic drive double-pressurization type water purification implementation method integrating the RO reverse osmosis membrane and the pump is mainly suitable for reverse osmosis type water purification systems of reverse osmosis membranes as shown in figures 7 and 8, and in a preferred embodiment of the implementation method, a cabin inside the device is divided into a front-stage water production cabin and a rear-stage pressurization cabin which are respectively used for low-pressure pressurization reverse osmosis water production, and the rear stage utilizes the pressure difference between waste water discharge and pure water to realize pressure difference pressurization drive. The realization device is provided with corresponding interfaces of water inlet and outlet between the front-section water making cabin and the rear-section pressurizing cabin, and two silica gel check valves are arranged in a pure water channel in the rear-section pressurizing cabin so as to be matched with the drive of the silica gel diaphragm. An adjustable flow control valve or a fitting for throttling the waste water ratio is arranged outside the shell and used for adjusting the waste water outlet rate.

The method is characterized in that a low-pressure intercepting supercharging organ is arranged in the front water production cabin, a silica gel diaphragm linkage supercharging organ is arranged in the rear supercharging cabin, and a hydraulic driving double-supercharging water purification mode is formed in tandem. As is known, the RO reverse osmosis membrane water purification system also has the characteristics that the wastewater is required to be discharged while producing the pure water, and the wastewater pressure is higher than the pure water pressure, therefore, the invention pressurizes the pure water by utilizing the pressure of the wastewater discharged by the water purification system, and uses a delicate non-electric driving pressurizing device, in particular to utilize the pressure difference energy to drive a silica gel diaphragm to move repeatedly so as to increase the pure water yield of the reverse osmosis water purification system and increase the pure water output pressure.

In the front water making cabin 20, a water source inlet 59 is arranged above the head cover 11, a low-pressure intercepting and pressurizing mechanism is arranged in the head cover 11, when the water source is in a low-pressure state, the water pressure is increased by a mechanism of intercepting the water source and delaying releasing, so that the constant maintenance of not less than 1.5kgf/cm is realized²The pressure of the water enters the water making chamber, so that the reverse osmosis water purifier can maintain the efficient production of pure water and reduce the waste water dischargeAnd (6) discharging. The system water cabin below is equipped with a slot that is used for cartridge RO reverse osmosis membrane filter core, is equipped with the pure water outlet in the slot, and cabin inboard side has a first waste water export 15, and the waste water export runs through the cabin outside, is equipped with the accessory that a quick connector connects adjustable flow control valve or throttle waste water ratio.

The low-pressure intercepting booster organ of the method of the invention is divided into an upper chamber and a lower chamber by an intercepting valve plate, and comprises the following components: the head cover, the U-shaped plastic part with the screw teeth, the first spring and the cut-off valve plate, wherein the side surface of the U-shaped plastic part is provided with a water outlet, and the bottom of the U-shaped plastic part is provided with a through pressure hole communicated with the water making cabin. The low-pressure cut-off booster is limited to the inflow pressure of 1.2-1.4 kgf/cm due to the elastic coefficient of the first spring²The cutoff boost mode is enabled only when in range. When the inflow water flowing pressure is in the range, the elastic force of the spring can prop the position of the interception valve plate to exceed three water outlets on the side surface of the U-shaped plastic part, so that the water source is intercepted. After the water source is intercepted and the flow is stopped, the upper cavity of the U-shaped plastic part is rapidly in a gradually-pressurized state, so that the interception valve plate is compressed and descended by the first spring driven by accumulated water pressure in the upper cavity, meanwhile, pure water and waste water in the front and rear cabin are continuously discharged to be in a low-pressure state, and the lower cavity is also in a low pressure state due to the fact that the through pressure hole is communicated with the water making cabin, thereby being beneficial to the descent of the interception valve plate. When the water source in the upper chamber is accumulated and pressurized to 1.5kgf/cm²When the water source is in a water-making state, the water flow enters the water-making cabin, the pressure in the lower cavity is increased rapidly due to the fact that the lower cavity is communicated with the pressure through hole, and the elastic force of the first spring props up the cutoff valve plate again to intercept a water source.

The water inlet pressure is increased by repeatedly and circularly utilizing the mechanisms of intercepting the water source and delaying the discharge so as to realize the purpose of keeping the water source constant to be not lower than 1.5kgf/cm²The pressure of the water enters the water producing chamber 20, so that the RO reverse osmosis water purifier can keep producing pure water efficiently and reduce the discharge of waste water. When the flowing water pressure of the water source is more than 1.5kgf/cm²When the pressure is higher than the pressure, the constant position of the cut-off valve plate is lower than the position of the water outlet on the side surface of the U-shaped plastic part, and the low-pressure cut-off booster is closedIn the state without the cutoff pressurization effect; when the flowing water pressure of the water source is less than 1.1kgf/cm²When the water source is closed, the water source enters the water making cabin; only the flowing water pressure of the water source is 1.2-1.4 kgf/cm²The method works, and of course, the frequency of the water source stopping and the delayed releasing are different in the range.

The rear-stage pressurizing cabin of the method of the invention is provided with a pure water inlet and a waste water inlet which are connected with the front-stage water making cabin, and an umbrella-shaped silica gel check valve is arranged in the pure water inlet to prevent the pure water from flowing backwards after entering the pure water chamber. A silica gel diaphragm linkage supercharging organ is arranged in the rear-section supercharging cabin, and the silica gel diaphragm on the organ divides the supercharging cabin into a pure water chamber and a waste water chamber. Wherein the interior fluid intercommunication of pure water cavity in the entry and the export of pure water, also be equipped with an umbrella type silica gel check valve in the pure water export to it is palirrhea to prevent that the pure water from depositing in behind the water storage bucket. And the interior fluid of waste water cavity communicates in the entry and the export of waste water each other, because the diameter of waste water entry is greater than the waste water export, waste water cavity pressure is greater than pure water cavity pressure, and the water pressure of pure water export is less than the water pressure of waste water export promptly, just can promote the silica gel diaphragm to move to the pure water cavity according to pressure differential principle waste water to increased pure water output pressure, the pure water of pressure increase is poured into the water storage bucket through the export through the extrusion of silica gel diaphragm in. When the waste water pushes the silica gel diaphragm, the linkage lever bracket and the linkage supporting rod sleeved with the spring are also driven to move towards the waste water cavity, the linkage supporting rod sleeved with the second spring drives the U-shaped fork of the linkage lever bracket to pull open the piston column in the movement stroke, at the moment, the waste water is rapidly discharged through the outlet, and the pressure in the waste water cavity is instantly lost; then the silica gel diaphragm resets, and the linkage bracing piece that the cover has the second spring in the silica gel diaphragm reset stroke drives the U type fork of linkage lever support and can stir the piston post and plug the waste water export again, and the waste water cavity internal pressure increases rapidly this moment, repeatedly promotes the silica gel diaphragm and moves to the pure water cavity again. The hydraulic pressurization mode of the invention can be realized by repeating the steps.

The silica gel diaphragm linkage supercharging mechanism in the method of the invention has the advantages that the specific structure is not repeated as described above. The device, the system and the method can keep the TDS (total dispersed solids) value of pure water constant, increase the output pressure of the pure water, efficiently save more than 95 percent of wastewater discharge, automatically close and start the system, completely adopt a mechanical structure, do not adopt any electric appliance control element, completely avoid the failure of electronic parts, have stable product quality, reduce the after-sale maintenance and service cost, save water and electricity for a long time, and are environment-friendly and energy-saving.
