Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water treatment equipment, in particular to an intelligent dynamic water-saving two-stage reverse osmosis water treatment equipment. BACKGROUND

[0002] In the field of water treatment, the intelligent dynamic water-saving two-stage reverse osmosis water treatment equipment is a key device for efficient water quality purification. Its core function is to deeply filter the water source through two-stage reverse osmosis technology to remove impurities, ions, and harmful microorganisms, and to optimize water resource utilization and reduce energy consumption through intelligent dynamic control. The equipment is widely used in industrial water treatment, seawater desalination, drinking water purification and other scenes, and has important significance for water quality safety and water resource recycling.

[0003] The traditional two-stage reverse osmosis water treatment equipment has significant shortcomings. In terms of filtration efficiency, a single filtration structure is easily clogged by impurities, resulting in a decrease in processing capacity, and lacks an automatic backwashing or dredging mechanism, requiring frequent manual disassembly and cleaning, which is high in maintenance cost and affects the continuity of water treatment. In terms of water-saving performance, the traditional equipment usually runs in a fixed mode and cannot dynamically adjust the reverse osmosis parameters according to water quality changes, resulting in waste of water resources. In addition, the equipment has low intelligence, cannot monitor the filtration state in real time and automatically optimize the operation, and is prone to affect the water quality due to the expiration or clogging of the filter core without timely replacement. The equipment has a complex structure design, poor coordination between components, and poor connection of the two-stage processing process, further reducing the overall processing efficiency. These problems restrict the application of traditional equipment in large-scale water treatment, and it is urgent to improve the automation level, anti-clogging ability and water-saving performance through technological innovation.

[0039] Second embodiment: as follows Figures 1 to 8 As shown, the secondary processing mechanism 4 includes a third chute 41, which is formed in the wall of the processing tube 1 and is located below the first chute 32. A cleaning groove 42 is formed through the inner surface of the processing tube 1 and passes through the third chute 41.

[0040] A sealing ring 43 is slidably connected inside the No. 3 chute 41. The bottom of the sealing ring 43 is fixedly connected to the pressure plate 39 through a groove reserved on the inner surface of the bottom of the processing pipe 1. An alignment groove 44 is opened through the inner surface of the sealing ring 43. The alignment groove 44 and the cleaning groove 42 are of the same shape and are distributed in the same way. Initially, the alignment groove 44 and the cleaning groove 42 are misaligned.

[0041] A rotating ring 45 is rotatably connected to the upper surface of the middle part of the filter disc 31. A thread is provided on the outer surface of the middle part of the drive rod 38. The inner surface of the rotating ring 45 is threadedly connected to the outer surface of the drive rod 38. A cleaning rod 46 is fixedly connected to the outer surface of the rotating ring 45.

[0042] The upper surface of the driving ring 33 is fixedly connected with an extrusion capsule 410, the inside of the rotating ring 45 is hollow, the upper surface of the rotating ring 45 is rotatably connected with an adaptive ring 411, the upper surface of the adaptive ring 411 is fixedly and communicatively provided with a hose 412, the end of the hose 412 away from the adaptive ring 411 is in communication with the extrusion capsule 410 through the driving ring 33, the inside of the cleaning rod 46 is hollow, the inside cavity of the cleaning rod 46 is in communication with the inside cavity of the rotating ring 45, and the bottom of the cleaning rod 46 is fixedly connected with an expansion sheet 413.

[0043] In work, when water treatment is needed, the device can be installed at the end of two water pipes by bolt fixation, and water is supplied from one side of the water pipe. In normal working condition, water enters from one side of the water pipe, flows to the other side of the water pipe after being filtered by the filter plate, and completes water treatment. As the impurities on one side of the filter plate gradually increase, the filter plate will be gradually 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 sliding groove 32 under the action of water pressure. The movement of the driving ring 33 will drive the connecting rod 34 to move upward, and then the driving rod 38 will move upward, thereby pulling the pressure disc 39 to move upward and gradually approach the sealing disc 310 and adhere to the lower surface of the sealing disc 310, thereby closing the upper and lower dislocation grooves 311 and 312, and forming a sealed cavity above the sealing disc 310. At this time, the continuous upward movement of the driving rod 38 will drive the sealing disc 310 to move upward along the sliding rod 314, thereby increasing the water pressure in the cavity above the sealing disc 310 and generating a reverse extrusion force on the filter plate, thereby generating a reverse extrusion force on the impurities blocked in the filter plate to make them separate from the filter plate 31. After the filter plate 31 is unblocked, the pressure disc 39 and the sealing disc 310 are reset under the action of the elastic force to make the filter plate 31 work again, thereby automatically unblocking the filter plate 31 during water treatment, greatly extending the working time of the device and avoiding the problem of insufficient water treatment efficiency caused by frequent cleaning of the device. When the driving rod 38 moves upward, the rotating ring 45 will be driven to rotate by the thread, and then the cleaning rod 46 will start to rotate, thereby stirring and cleaning the upper surface of the filter plate 31 in cooperation with the pressure disc 39 and the sealing disc 310, avoiding the problem of poor cleaning effect caused by the impurities being immediately blocked on the upper surface of the filter plate 31 after being cleaned, greatly improving the working time of the device, and thereby greatly improving the water treatment effect of the device. When the pressure disc 39 moves upward, the sealing ring 43 will move upward synchronously, and finally the positioning groove 44 will be aligned with the cleaning groove 42, thereby opening the middle part of the treatment pipe 1, and making the stirred impurities be output to the outside of the treatment pipe 1 along the cleaning groove 42 in cooperation with the pressure disc 39 and the cleaning rod 46. When the filter plate 31 is cleaned, the pressure disc 39 is reset to drive the sealing ring 43 to reseal the cleaning groove 42, thereby automatically opening the cleaning groove 42 to release the impurities after being stirred, avoiding the problem that the filter plate 31 cannot be effectively unblocked by the cleaning rod 46 and the pressure disc 39 due to excessive impurities accumulated on the filter plate 31 after long-term use, further improving the anti-blocking effect of the device, thereby further improving the service life of the device, reducing the maintenance frequency, and greatly improving the water treatment efficiency. When the driving ring 33 moves upward, the extrusion capsule 410 will be extruded, thereby increasing the internal pressure of the extrusion capsule 410, and the pressure will be transmitted to the inside of the rotating ring 45 through the hose 412, and finally input to the internal cavity of the cleaning rod 46, thereby making the expansion piece 413 at the bottom of the cleaning rod 46 start to expand and tightly adhere to the upper surface of the filter plate 31.Further, the cleaning ability of impurities is further improved by the friction between the expansion sheet 413 and the filter sheet when the filter disc 31 is cleaned, and the problem of impurities with strong adhesion being unable to be effectively cleaned because of being adhered to the filter disc 31 is avoided.
