[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] A concentrate reverse osmosis device according to an embodiment of this application includes an existing concentrate reverse osmosis system, which includes an existing security filter, an existing high-pressure pump, and an existing reverse osmosis device from the inlet to the outlet, and the existing security filter, the existing high-pressure pump, and the existing reverse osmosis device are connected in series via pipelines; a new concentrate reverse osmosis system is added, which includes a new security filter, a new high-pressure pump, and a new reverse osmosis device from the inlet to the outlet, and the new security filter, the new high-pressure pump, and the new reverse osmosis device are connected in series via pipelines; the new water reverse osmosis system and the existing concentrate reverse osmosis system are connected in parallel.

[0024] Specifically, on the concentrate reverse osmosis feed side of the concentrate reverse osmosis device of this application: the inlet of the newly added security filter is connected to the feed header of the original concentrate reverse osmosis system by a pipeline to realize the parallel relationship between the new and the original systems; a pneumatic butterfly valve is installed on the inlet and outlet sections of the pipelines of the new security filter and the original security filter; the outlets of the new security filter and the original security filter are connected to the inlets of the new high-pressure pump and the original high-pressure pump by pipelines; the outlets of the new high-pressure pump and the original high-pressure pump are connected to the inlets of the new reverse osmosis equipment and the original reverse osmosis equipment by pipelines, and each of these sections is equipped with a check valve, a manual butterfly valve, and a pneumatic butterfly valve.

[0025] On the concentrate / permeable side of the reverse osmosis system: connect the permeable end of the new reverse osmosis unit to the main pipe of the existing reverse osmosis unit's permeable water to the intermediate water tank via a pipeline, and install check valves and pneumatic butterfly valves on each section; connect the return water from the new reverse osmosis unit to the cleaning water tank via a pipeline to the existing reverse osmosis unit's return water main pipe, and install a manual valve; divide the concentrate from the new reverse osmosis unit into two lines, one line connected to the existing reverse osmosis unit's concentrate to backwash water tank main pipe via a pipeline, and install a manual butterfly valve and check valve on each section; connect the other line to the water treatment plant's drainage ditch and discharge into the clean wastewater network via a pipeline, and install a pneumatic butterfly valve on this section; connect the return water from the new reverse osmosis unit's cleaning water to the existing reverse osmosis unit's cleaning water tank main pipe via a pipeline.

[0026] It should be noted that the original and newly added security filters, the original and newly added high-pressure pumps, and the original and newly added reverse osmosis equipment have the same structure.

[0027] Understandably, by connecting the new concentrate reverse osmosis system in parallel with the existing concentrate reverse osmosis system, the concentrate can be treated by the new system during the shutdown for cleaning or maintenance of the existing system, thus preventing the concentrate from being directly discharged into the clean water sewer network and improving the water system's recovery rate.

[0028] In some specific embodiments of this application, such as Figure 1 and Figure 2 As shown, the security filter includes a housing 1, and multiple filter elements 2 are uniformly arranged circumferentially inside the housing 1. The multiple filter elements 2 are used to intercept impurities.

[0029] It should be noted that the side wall of the outer casing 1 is connected to the water inlet 11, the water outlet 12 and the sewage outlet 13 respectively.

[0030] Among them, multiple filter elements 2 are fitted with fixing rings 21, and the outer diameter of the fixing rings 21 is smaller than the inner diameter of the outer shell 1.

[0031] Understandably, the retaining ring 21 can stabilize multiple filter elements 2 and prevent them from tipping over during use.

[0032] like Figures 2-4 As shown, the outer shell 1 is coaxially rotatably equipped with a water purification chamber 3, and multiple filter elements 2 are inserted into the water purification chamber 3.

[0033] Specifically, an impeller 31 is coaxially inserted at the bottom of the water purification chamber 3. The impeller 31 is used to change the direction of water flow. A rotating shaft 311 is coaxially fixed at the top of the impeller 31. The rotating shaft 311 is fixed to the top of the water purification chamber 3.

[0034] It should be noted that, in the specific embodiments of this application, the impeller 31 is provided with a plurality of circumferentially evenly distributed arc-shaped channels, which change the water flow from vertical to horizontal, and generate rotational potential energy on the impeller 31 as the water flows through the arc-shaped channels inside the impeller 31, and drive the impeller 31 to rotate through the potential energy.

[0035] Therefore, it can be understood that after the concentrated water is filtered by the filter element 2, it will enter the water purification chamber 3 and can only flow out from the impeller 31. The water flow drives the impeller 31 to rotate, which in turn drives the water purification chamber 3 to rotate. It can be understood that the multiple filter elements 2 inserted into the water purification chamber 3 and forming an integral part will rotate synchronously and in the same direction with the water purification chamber 3. It can be further understood that at this time, the water that enters the shell 1 from the inlet 11 but does not enter the filter element 2 will be agitated and rotate inside the shell 1. Thus, the impurities blocked by the filter element 2 will be thrown towards the inner wall of the shell 1 by centrifugal force.

[0036] It should be noted that the top of the water purification chamber 3 is set as an inclined top 32, with the axis of the inclined top 32 being higher than the edge, which can prevent impurities in the water from accumulating at the top of the water purification chamber 3.

[0037] Furthermore, multiple partitions 33 are fixedly connected to the inclined top 32, and the multiple partitions 33 are respectively spaced apart from the multiple filter elements 2.

[0038] It can be understood that the rotating water purification chamber 3 will simultaneously drive multiple baffles 33 to rotate. During the rotation process, the baffles 33 will further apply centrifugal force to the impurities. In conjunction with the inclined top 32, impurities will be further prevented from accumulating at the top of the water purification chamber 3, thereby improving the efficiency of impurity discharge.

[0039] It should be noted that a waste storage plate 4 is provided around the water purification chamber 3. The waste storage plate 4 is coaxially fixed to the outer shell 1. The water purification chamber 3 and the waste storage plate 4 are sealed and rotatably connected. The water outlet 12 is located on the bottom side of the waste storage plate 4, and the sewage outlet 13 is located on the top side of the waste storage plate 4.

[0040] It should be further explained that, such as Figure 2 and Figure 3 As shown, the cross-section of the waste storage plate 4 is Z-shaped, and the end that effectively stores waste is lower than the top of the clean water tank 3.

[0041] It is understandable that impurities will be thrown towards the dirt storage plate 4 under the effect of centrifugal force and accumulate on the effective storage end of the dirt storage plate 4. When the security filter is not in use, the impurities can be discharged from the drain port 13, effectively reducing the accumulation of impurities inside the water inlet of the housing 1. The purified concentrated water is discharged from the impeller 31 and then from the outlet 12.

[0042] In summary, this design of the security filter utilizes centrifugal force to gather impurities for easy discharge, effectively reducing the amount of impurities accumulated inside. Secondly, the use of water flow to drive the rotation of multiple filter elements 2 can, to a certain extent, reduce the adhesion of impurities on their outer walls, extend the service life of the filter elements 2, and reduce the frequency of replacement or cleaning.

[0043] It should be noted that the specific model and specifications of filter element 2 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0044] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
