[0030] Figures 1 to 3 An embodiment of the overflow water recovery system of the cleaning machine of the present application is schematically shown.

[0031] As Figures 1 to 3 shown, the present application discloses an overflow water recovery system for a cleaning machine. The cleaning machine includes an overflow tank and is configured with a water tank 1 and a reverse osmosis filter 2. The overflow water recovery system of the cleaning machine of the present application includes: an overflow water collection tank 3, and the overflow water collection tank 3 is communicated with the overflow tank of the cleaning machine. A concentrated water tank 4, the concentrated water tank 4 is connected in series with the overflow water collection tank 3, and the concentrated water tank 4 is simultaneously connected to the concentrated water end of the reverse osmosis filter 2. A reverse osmosis recovery assembly, the reverse osmosis recovery assembly includes a multi-stage filter, and the concentrated water tank 4 is connected to the water tank 1 of the cleaning machine through the reverse osmosis recovery assembly.

[0032] Through the above structural design, the overflow water recovery system of the cleaning machine in this embodiment includes: an overflow water collection tank 3, a concentrated water tank 4, and a reverse osmosis recovery component, which is applied to the recovery of the overflow water of the cleaning machine. Among them, the cleaning machine includes an overflow tank, and is configured with a water tank 1 and a reverse osmosis filter 2. The overflow water collection tank 3 is connected to the overflow tank of the cleaning machine to collect the overflow water, and then is connected in series with the concentrated water tank 4, and the overflow water and the concentrated water are mixed and then enter the reverse osmosis recovery component. The reverse osmosis recovery component includes a multi-stage filter, and the concentrated water tank 4 is connected to the water tank 1 of the cleaning machine through the reverse osmosis recovery component. In this application, by setting the overflow water collection tank 3 to communicate with the overflow tank of the cleaning machine, the overflow water of the overflow tank is collected and recovered, and after being mixed with the concentrated water in the concentrated water tank 4, it is filtered and cleaned by the reverse osmosis recovery component together and then transported back to the water tank 1 of the cleaning machine, realizing the recycling of the overflow water and improving the recovery rate of the overflow water.

[0033] In some embodiments of this application, for the working conditions where multiple cleaning machines work in parallel or in series at the same time, the overflow water collection tank 3 can be connected to the overflow tanks of multiple cleaning machines at the same time to recover the overflow water of all cleaning machines and improve the recovery rate of the overflow water. For example, the conductivity of the overflow water of a single flat cleaning machine < 20 μs / cm, the external discharge volume: 1 - 2 t / h; the conductivity of the overflow water of a single tank cleaning machine < 10 μs / cm, the external discharge volume: 2 - 3 t / d; the conductivity of the concentrated water in the concentrated water tank 4 is 1000 - 1200 μs / cm, and the output is 10 t / h. In some embodiments of this application, multiple flat cleaning machines and tank cleaning machines can be used in combination, and their overflow water can be collected through the overflow water collection tank 3. Thus, about 500 t of overflow water can be collected every day. The overflow water is mixed with the concentrated water in the concentrated water tank 4 to obtain mixed water with a conductivity of about 200 μs / cm. This mixed water can be filtered and recovered by the reverse osmosis recovery component and finally returned to the water tank 1 of the cleaning machine to reduce the water consumption for cleaning.

[0034] In some embodiments of this application, as Figure 2 shown, an overflow water inlet end 31 is provided at the top of the overflow water collection tank 3, and an overflow water outlet end 32 is provided at the lower end of the overflow water collection tank 3, so as to facilitate the collection and discharge of the overflow water. Among them, in the preferred embodiment of this application, the overflow water inlet end 31 is connected to the upper end of the overflow tank of the cleaning machine, so as to collect the supernatant liquid at the upper end of the overflow tank, so as to control the cleanliness of the overflow water from the source, reduce the filtering difficulty, and improve the filtering cleanliness of the overflow water. At the same time, the overflow water outlet end 32 is connected to the lower end water inlet of the concentrated water tank 4 to facilitate the mixing of the overflow water and the concentrated water.

[0035] In some embodiments of this application, as Figure 2As shown in the figure, a pH meter and an external discharge port are provided on the side of the overflow water collection tank 3 facing away from the concentrated water tank 4. When the pH meter detects that the pH value of the overflow water is greater than 9, it is considered that the cleanliness of the overflow water does not meet the standard. At this time, the external discharge port automatically discharges the overflow water directly through a valve, so that it does not enter the concentrated water tank 4 for recycling.

[0036] In some embodiments of the present application, as Figure 1 shown, the reverse osmosis recovery assembly includes: a reverse osmosis recovery security filter 5 and a reverse osmosis recovery filter 6 arranged in sequence from front to back. Among them, the reverse osmosis recovery security filter 5 is a 0.5μm tubular filter element filter, using, for example, a PP meltblown filter element; the reverse osmosis recovery filter 6 is a RO (Reverse Osmosis) membrane filter. The principle of the RO membrane filter is: under a certain pressure, water molecules can pass through the RO membrane, while impurities such as inorganic salts, heavy metal ions, organic substances, colloids, bacteria, and viruses in the water cannot pass through the RO membrane, so that the permeated pure water and the non-permeable concentrated water can be strictly separated to achieve the water quality purification of reverse osmotic pressure.

[0037] In this embodiment, the overflow water of the cleaning machine is collected in the overflow water collection tank 3 by the self-retaining method. The overflow water collection tank 3 is connected in series with the concentrated water tank 4 of the pure water system. After the concentrated water and the overflow water are mixed, they are first filtered by the 0.5μm reverse osmosis recovery security filter 5, and then processed by the RO membrane reverse osmosis recovery filter 6 and then transported to the water tank 1 of the pure water system to realize the reuse of the overflow water.

[0038] In some embodiments of the present application, as Figure 1 shown, a reverse osmosis high-pressure pump 21 is provided at the inlet end of the reverse osmosis filter 2, and a reverse osmosis recovery high-pressure pump 61 is provided at the inlet end of the reverse osmosis recovery filter 6 to achieve the high pressure required for reverse osmosis filtration. A reverse osmosis recovery booster pump 51 is provided at the inlet end of the reverse osmosis recovery security filter 5 to increase the water flow pressure for the filtration of the tubular filter element.

[0039] In some embodiments of the present application, as Figure 2 shown, the reverse osmosis recovery booster pump 51 includes multiple groups connected in parallel to achieve simultaneous pumping and pressure boosting of multiple groups, facilitating flow control and alternating use or maintenance.

[0040] In some embodiments of the present application, as Figure 2 shown, a check valve 52 is provided at the outlet end of each reverse osmosis recovery booster pump 51. The check valve 52 is also called a non-return valve, which is an automatic valve that relies on the pressure of the flowing medium in the pipeline to push the valve flap to achieve the closing and opening of the valve, and can prevent the backflow of water and ensure the safety of the pipeline. In addition, as Figure 2 shown, a pressure indicator 53 is further provided at the outlet end of the check valve 52 to achieve pressure detection and warning, further improving the operation safety of the system.

[0041] In some embodiments of the present application, continuing as Figure 2 shown, a protection butterfly valve 54 is provided at the inlet end of each reverse osmosis recovery booster pump 51 and the outlet end of the check valve 52. The protection butterfly valve 54 is used to achieve isolation and protect the check valve 52 and the safety of other equipment. Especially in multiple groups of parallel pumps, the protection butterfly valve 54 can effectively bear the impact force generated when one pump is not started.

[0042] In some embodiments of the present application, both the overflow water collection tank 3 and the concentrated water tank 4 are made of PP (polypropylene), which has the advantages of light weight, general use, chemical corrosion resistance, heat resistance, and insulation. Each booster pump and high-pressure pump are made of SUS304 stainless steel to have high corrosion resistance and strength, and to improve the service life.

[0043] Figure 3 shows a schematic diagram of the overflow water recovery process of the overflow water recovery system of the cleaning machine of the present application. As Figure 3 shown, above the overflow water recovery system of the cleaning machine in the embodiment of the present application is the pure water system for the cleaning machine. In the pure water system, the tap water inlet passes through the raw water tank and the raw water pump to achieve inlet buffer storage and pumping, and then enters the plate heat exchanger through the bag filter device to adjust the temperature. Then, it passes through ultrafiltration and the security filter to form filtered water, which enters the water tank 1 for storage. The filtered water after ultrafiltration in the water tank 1 continues to be pressurized by the reverse osmosis high-pressure pump 21, and then penetrates through the RO membrane to achieve reverse osmosis filtration at the reverse osmosis filter 2. The pure water formed by reverse osmosis is used as the water for the cleaning machine, while the concentrated water formed by reverse osmosis enters the concentrated water tank 4 for subsequent mixed filtration and recovery. The overflow water collection tank 3 collects the overflow water of the cleaning machine and merges it into the concentrated water tank 4 for mixing. The mixed water flow passes through the reverse osmosis recovery security filter 5 and the reverse osmosis recovery filter 6 for filtration successively. Among them, the purified water after reverse osmosis filtration by the reverse osmosis recovery filter 6 is transported back to the water tank 1 for recycling, and the concentrated water after reverse osmosis filtration is directly discharged.

[0044] In summary, the overflow water recovery system of the cleaning machine according to the embodiments of the present application includes an overflow water collection tank, a concentrated water tank, and a reverse osmosis recovery component, and is applied to the recovery of the overflow water of the cleaning machine. Among them, the cleaning machine includes an overflow tank and is configured with a water tank and a reverse osmosis filter. The overflow water collection tank is connected to the overflow tank of the cleaning machine to collect the overflow water, and then, by being connected in series with the concentrated water tank, the overflow water and the concentrated water are mixed and then enter the reverse osmosis recovery component. The reverse osmosis recovery component includes a multi-stage filter, and the concentrated water tank is connected to the water tank of the cleaning machine through the reverse osmosis recovery component. By setting the overflow water collection tank to communicate with the overflow tank of the cleaning machine, the overflow water in the overflow tank is collected and recovered, and after being mixed with the concentrated water in the concentrated water tank, the mixture is filtered and cleaned by the reverse osmosis recovery component and then transported back to the water tank of the cleaning machine, realizing the recycling of the overflow water and improving the recycling utilization rate of the overflow water.

[0045] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
