Description

Technical Field

[0001] The utility model belongs to the technical field of water purification devices, in particular to a large-scale water vending machine with double water outlets. Background Art

[0002] A large-scale dual-outlet water vending machine is an advanced water purification device capable of providing both purified and nanofiltered water to meet diverse drinking water needs. The machine processes raw water through a multi-media filter, activated carbon filter, and softening device. The machine then pumps pressurize water, using membranes to reduce the higher-concentration water to a lower-concentration level. This system also isolates impurities such as industrial pollutants, heavy metals, bacteria, and viruses, effectively removing harmful substances and impurities while retaining beneficial minerals and trace elements. This ensures that the water meets the required physical and chemical indicators and hygienic standards for drinking water, producing the purest and clearest water. This type of water vending machine is widely used in industrial and indoor settings. For reverse osmosis or nanofiltration equipment, the flow rate of large-scale equipment is generally greater than 3L / min. To maintain the required processing flow, large-scale dual-outlet water vending machines require two separate water production systems to filter the two different water qualities. This results in a large footprint and high construction costs for existing dual-outlet water vending machines. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical problems, technical solutions, and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. The technical solutions of the present invention will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0023] See also Figures 1 to 3 This embodiment proposes a large-scale water vending machine with dual water outlets, including a common filtration system, two membrane treatment systems and two water vending systems arranged in a frame 8; the two membrane treatment systems share a common filtration system, and the two membrane treatment systems are respectively connected to a water vending system to output water separately.

[0024] The public filtration system includes a filter tank 1, a reclaimed water tank 4, an ultraviolet sterilizer 5, a high-pressure pump 6, and a safety filter 7; both membrane treatment systems include a membrane shell 2 and a water production tank 10; the types of membrane shells 2 of the two membrane treatment systems are different to obtain different types of water; the membrane shells 2 can be ultrafiltration membranes, nanofiltration membranes, and reverse osmosis membranes; the types of membrane shells 2 of the two membrane treatment systems can be arbitrarily combined according to specific process requirements.

[0025] Since there are two membrane housings 2 but only one set of other equipment, the equipment and piping within the rack 8 need to be arranged to minimize the footprint of the water vending machine so that the two membrane treatment systems can share a common filtration system. Within the rack 8, three filter tanks 1 are vertically arranged in series in the center. One of the filter tanks 1 is connected to a salt tank 3, which is located on one side of the filter tank 1. The salt tank 3 is used for maintaining the filter tank 1 and for processing resin. Two membrane housings 2 and a high-pressure pump 6 are vertically arranged in front of the filter tank 1. A gray water tank 4 is located below the filter tank 1; three ultraviolet sterilizers 5 are located below the gray water tank 4. Some piping at the rear of the rack 8 is located below the gray water tank 4. Two water production tanks 10 are located on one side of the filter tank 1, with a safety filter 7 located below the water production tank 10. The water vending system is located on both sides of the rack 8.

[0026] The water inlet of the filter tank 1 is connected to the tap water pipeline through an ultraviolet sterilizer 5. The purified water outlet of the filter tank 1 is connected to the recycled water tank 4, which is connected to the safety filter 7. The safety filter 7 is connected to the membrane housing 2 via a high-pressure pump 6. The membrane housing 2 is connected to the production water tank 10, which is connected to the water inlet of the water vending system. The pipelines connecting the inlets of the two membrane treatment systems are equipped with electric valve groups. The PLC controller controls the switching of the electric valve groups to switch the membrane treatment systems. The electric valve groups consist of a first electric valve 91, a second electric valve 92, and a third electric valve 93. Each of the first, second, and third electric valves 91, 92, and 93 is an electric three-way valve. When the first, second, and third electric valves 91, 92, and 93 are switched to the same pipeline group and are detected to be in place and normal, the system begins water production. When the water level in the production water tank 10 reaches the upper limit, the PLC controller controls the electric valve groups to switch to the other pipeline group and start water production. When both water production tanks 10 are full of water, the electric valve group maintains the status quo and the equipment automatically shuts down.

[0027] Arranging the membrane shell 2, the grey water tank 4, the salt tank 3, the safety filter 7, the water production tank 10, and some pipelines that are most closely related to the filter tank 1 can shorten the pipeline connections between the various devices to the greatest extent. The water discharged from the filter tank 1 can directly enter the grey water tank 4 for buffering, and the water in the grey water tank 4 directly enters the safety filter 7, and then can directly pass through the membrane shells 2 of the two membrane treatment systems for the next step of processing, greatly reducing the internal space of the dual-outlet water vending machine.

[0028] An electric control box 11 is also provided in the frame 8 , and is located in front of the water production tank 10 .

[0029] Frame 8 fronts are provided with double doors. The left side door is a two-door linkage, comprising a water selling door and a window door 12, and the water selling door is provided with an electric control system window, and an electric control box 11 is fixed on top of the water selling door, and the right side door is another water selling door.

[0030] The water vending machine has two water production systems, sharing the filter tank 1, the intermediate water tank 4, the safety filter 7, the high-pressure pump 6 and other accessories. There are two membrane treatment systems. The ultrafiltration membrane, nanofiltration membrane and reverse osmosis membrane can be arbitrarily combined according to specific process requirements. The two membrane treatment systems use their own water production tanks 10.

[0031] The water vending machine includes two water vending systems, which include a water vending pump and a solenoid valve. The two water production tanks 10 are connected to the water vending pump through two ultraviolet sterilizers 5 and then connected to the pure water inlet of the water vending system.

[0032] The working principle of a large-scale water vending machine with two water outlets proposed in this embodiment is as follows:

[0033] The water inlet of the filter tank 1 is connected to the tap water pipeline through an ultraviolet sterilizer 5. The purified water outlet of the filter tank 1 is connected to a reclaimed water tank 4. The initially filtered water is stored in the reclaimed water tank 4, which is then connected to a safety filter 7 for further filtration. The safety filter 7 is connected to each of the two membrane housings 2 via a high-pressure pump 6. Because the reclaimed water tank 4 provides a buffer, the high-pressure pump 6 is prevented from frequently activating due to irregular tap water pressure, ensuring system stability. The two membrane housings 2 are connected to the high-pressure pump 6 via an electric valve. Water treated by the membranes within the membrane housings 2 flows through the electric valves into the production water tank 10. The production water tank 10 is connected to the pure water inlet of the water vending system via two other connections to the ultraviolet sterilizer 5 and the vending water pump.

[0034] The above-mentioned structure shares the filter tank 1, the intermediate water tank 4, the safety filter 7, the high-pressure pump 6 and other parts. The membrane treatment system adopts two systems. Through the intelligent switching of the electric valve, the membrane can switch categories according to the specific process, and the applicable pressure is manually adjusted, and the produced water enters the respective water tanks. There are water vending systems on both sides of the front of the water vending machine. The outlet water is sterilized by ultraviolet rays. There is a visual window structure in the middle of the front, and the overall structure of the equipment is displayed. The utility model optimizes the structure of large-scale water treatment equipment and combines the two water production systems into one. Under a reasonable layout, the footprint of the equipment is reduced and the cost of the equipment is reduced. It is easy to transport and install. The closed water purification device structure provided by the utility model can improve the sanitary quality of the whole machine and avoid secondary pollution of the water quality.

[0035] The above content is a further detailed description of the present invention in combination with a specific preferred embodiment. It cannot be determined that the specific embodiments of the present invention are limited to this. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the present invention, which should be regarded as belonging to the present invention and the scope of patent protection determined by the submitted claims.
