Description

Technical Field

[0001] The present invention relates to the technical field of water treatment equipment, and more specifically, to an intelligent dynamic water-saving double-stage reverse osmosis water treatment equipment. Background Art

[0002] In the field of water treatment, an intelligent dynamic water-saving double-stage reverse osmosis water treatment equipment is a key device for achieving efficient water quality purification. Its core function is to deeply filter the water source through double-stage reverse osmosis technology, removing harmful substances such as impurities, ions, and microorganisms. At the same time, it optimizes the water resource utilization rate through intelligent dynamic control and reduces energy consumption. This equipment is widely used in industrial water treatment, seawater desalination, drinking water purification and other scenarios, and is of great significance for ensuring water quality safety and promoting water resource recycling.

[0003] Traditional double-stage reverse osmosis water treatment equipment has significant deficiencies. In terms of filtration efficiency, a single filtration structure is easily blocked by impurities, resulting in a decrease in processing capacity. Moreover, it lacks an automatic backwashing or dredging mechanism, requiring frequent manual disassembly and cleaning, with high maintenance costs and affecting the continuity of water treatment. In terms of water-saving performance, traditional equipment usually operates in a fixed mode and cannot dynamically adjust reverse osmosis parameters according to water quality changes, resulting in water resource waste. In addition, the equipment has a low degree of intelligence, unable to real-time monitor the filtration status and automatically optimize the operation, and is prone to affecting the water quality due to the expiration of the filter element life or blockage without timely replacement. The equipment structure design is complex, the coordination between components is poor, and the double-stage treatment process is not smoothly connected, further reducing the overall treatment efficiency. These problems restrict the application of traditional equipment in large-scale water treatment, and there is an urgent need to improve the automation level, anti-blocking ability and water-saving performance through technological innovation.

[0017] According to an embodiment of the present invention, a rotating ring is rotatably connected to the upper surface of the middle part of the filter plate. A thread is provided on the outer surface of the middle part of the driving rod. The inner surface of the rotating ring is threadedly connected to the outer surface of the driving rod. A cleaning rod is fixedly connected to the outer surface of the rotating ring. A fixed ring is rotatably connected to the upper surface of the edge of the rotating ring.

[0019] (III) Beneficial effects

[0020] The present invention provides an intelligent dynamic water-saving double-stage reverse osmosis water treatment device, which has the following beneficial effects:

[0021] (I). In this intelligent dynamic water-saving double-stage reverse osmosis water treatment device, as the driving rod continues to move upwards, it will drive the sealing plate to move upwards along the sliding rod. Then, the water pressure in the cavity above the sealing plate increases, generating a reverse extrusion force on the filter plate, and further generating a reverse extrusion force on the impurities blocked at the filter plate, causing them to break away from the blockage of the filter disc. After the filter disc is unblocked, under the action of the elastic force, the pressure plate and the sealing plate reset and the filter disc resumes work. Thus, it realizes automatic dredging of the filter disc after being blocked during the water treatment process, greatly extending the working time of the device and avoiding the problem of insufficient water treatment efficiency caused by frequent cleaning of the device.

[0022] (2). In this intelligent dynamic water-saving double-stage reverse osmosis water treatment equipment, when the driving rod moves upward, it will drive the rotating ring to start rotating through the thread, and then drive the cleaning rod to start rotating. The pressure plate and the sealing plate are used to stir and clean the upper surface of the filter plate, avoiding the problem that impurities are immediately re-blocked on the upper surface of the filter plate just after being cleaned, resulting in poor cleaning effect. This greatly improves the working time of the equipment, and further significantly improves the water treatment effect of the equipment. When the pressure plate moves upward, it will synchronously drive the sealing ring to move upward, and finally make the alignment groove coincide with the cleaning groove, thereby opening the middle part of the treatment pipe. Together with the pressure plate and the cleaning rod, the stirred impurities are instantly output to the outside of the treatment pipe along the cleaning groove. When the cleaning of the filter plate is completed, the pressure plate resets and drives the sealing ring to re-close the cleaning groove, thus realizing the automatic opening of the cleaning groove to release the impurities after the impurities are stirred, avoiding the problem that the cleaning rod and the pressure plate cannot effectively dredge the filter plate due to excessive accumulation of impurities at the filter plate after long-term use, further improving the anti-blocking effect of the equipment, and then further improving the service life of the equipment, reducing the maintenance frequency, and at the same time significantly improving the water treatment efficiency.

[0023] (3). In this intelligent dynamic water-saving double-stage reverse osmosis water treatment equipment, when the driving ring moves upward, it will squeeze the extrusion bladder, thereby increasing the air pressure inside it. The air pressure is conveyed to the inside of the rotating ring through the hose and finally input into the internal cavity of the cleaning rod. As a result, the expansion piece at the bottom of the cleaning rod begins to expand and closely adheres to the upper surface of the filter plate, further improving the cleaning ability of impurities through the friction between the expansion piece and the filter plate during the cleaning of the filter plate, and avoiding the problem that impurities with strong adhesion cannot be effectively cleaned and adhere to the filter plate.

[0042] Second Embodiment: As Figures 1 to 8 shown, the secondary processing mechanism 4 includes a third sliding groove 41. The third sliding groove 41 is formed in the wall of the processing pipe 1. The third sliding groove 41 is arranged below the first sliding groove 32. A cleaning groove 42 is formed through the inner surface of the processing pipe 1. The cleaning groove 42 penetrates through the third sliding groove 41. The cleaning groove 42 is annularly distributed on the inner surface of the processing pipe 1.

[0043] A sealing ring 43 is slidably connected up and down in the third sliding groove 41. The bottom of the sealing ring 43 is fixedly connected to the pressure plate 39 through a notch reserved on the inner surface of the bottom of the processing pipe 1. A counterpoint groove 44 is formed through the inner surface of the sealing ring 43. The counterpoint groove 44 and the cleaning groove 42 are arranged in the same shape and distribution. The counterpoint groove 44 and the cleaning groove 42 are initially arranged in an offset manner.

[0044] A rotating ring 45 is rotatably connected to the upper surface of the middle part of the filter plate. A thread is arranged on the outer surface of the middle part of the driving rod 38. The inner surface of the rotating ring 45 is threadedly connected to the outer surface of the driving rod 38. A cleaning rod 46 is fixedly connected to the outer surface of the rotating ring 45.

[0045] The upper surface of the driving ring 33 is fixedly connected with an extrusion bladder 410. The inside of the rotating ring 45 is hollow. The upper surface of the rotating ring 45 is rotatably connected with an adaptation ring 411. The upper surface of the adaptation ring 411 is fixedly and communicatively penetrated by a hose 412. One end of the hose 412 away from the adaptation ring 411 penetrates the driving ring 33 and communicates with the extrusion bladder 410. The inside of the cleaning rod 46 is hollow. The internal cavity of the cleaning rod 46 communicates with the internal cavity of the rotating ring 45. The bottom of the cleaning rod 46 is fixedly connected with an expansion piece 413.

[0046] During operation, when water treatment is required, the device can be fixedly installed at the ends of the two water pipes by bolts, and water is passed from one water pipe. Under normal working conditions, water enters from one water pipe, passes through the filter plate and flows to the other water pipe to complete water treatment. As the impurities on one side of the filter plate gradually increase, the filter plate will gradually be blocked, causing the water pressure on one side of the filter plate to gradually increase, and then the driving ring 33 will be pushed to slide inward along the No. 1 slide groove 32 under the action of the water pressure. As the driving ring 33 moves, the connecting seat 37 will be driven to move upward through the connecting rod 34, and then the driving rod 38 will move upward, thereby pulling the pressure plate 39 to move upward and gradually approach the sealing plate 310 and gradually fit the lower surface of the sealing plate 310, thereby moving the upper dislocation groove 311 The upper and lower offset grooves 312 are closed, so that the sealing disk 310 forms a closed cavity. At this time, as the driving rod 38 continues to move upward, the sealing disk 310 will be driven to move upward along the sliding rod 314, thereby increasing the water pressure in the cavity above the sealing disk 310, generating a reverse squeezing force on the filter plate, thereby generating a reverse squeezing force on the impurities blocked at the filter plate, so that they are free from the blockage of the filter disk 31. After the filter disk 31 is unblocked, the lower pressure plate 39 and the sealing disk 310 are reset under the action of elastic force to make the filter disk 31 work again, thereby realizing automatic unblocking of the filter disk 31 after being blocked during the water treatment process, greatly extending the working time of the equipment and avoiding the problem of insufficient water treatment efficiency caused by the frequent need to clean the equipment. The groove drives the rotating ring 45 to start rotating, and then starts rotating through the cleaning rod 46, and cooperates with the pressure plate 39 and the sealing plate 310 to stir and clean the upper surface of the filter plate 31, so as to avoid the problem that the impurities are immediately blocked on the upper surface of the filter plate 31 after being cleaned, resulting in poor cleaning effect, which greatly improves the working time of the device and thus greatly improves the water treatment effect of the device. When the pressure plate 39 moves upward, it will synchronously drive the sealing ring 43 to move upward, and finally make the alignment groove 44 overlap and align with the cleaning groove 42, so as to open the middle part of the treatment tube 1, cooperate with the pressure plate 39 and the cleaning rod 46, so that the stirred impurities are instantly output to the outside of the treatment tube 1 along the cleaning groove 42, and when the filter plate 31 is cleaned, the pressure plate 39 resets and drives the sealing ring 43 to clean The cleaning groove 42 is re-closed, and the cleaning groove 42 is automatically opened to release the impurities after the impurities are stirred up, thereby avoiding the problem that the cleaning rod 46 and the pressure plate 39 cannot effectively dredge the filter disc 31 due to excessive impurities accumulated at the filter disc 31 after long-term use, further improving the anti-clogging effect of the device, thereby further improving the service life of the device, reducing the number of maintenance times, and greatly improving the water treatment efficiency. When the driving ring 33 moves upward, it squeezes the extrusion bag 410, thereby increasing the internal air pressure, and transmits the air pressure to the inside of the rotating ring 45 through the hose 412, and finally inputs it into the internal cavity of the cleaning rod 46, so that the expansion piece 413 at the bottom of the cleaning rod 46 begins to expand and fits tightly against the upper surface of the filter disc 31.Furthermore, when cleaning the filter disc 31, the friction between the expansion piece 413 and the filter piece is used to further improve the cleaning ability of impurities, avoiding the problem that impurities with strong adhesion adhere to the filter disc 31 and cannot be effectively cleaned.
