Abstract
Description
Technical Field
[0001] This invention relates to the field of industrial wastewater treatment, specifically to a high-efficiency reverse osmosis membrane water purification and reuse system for industrial wastewater treatment. Background Technology
[0002] Industrial production processes generate large amounts of wastewater containing various pollutants. Direct discharge of this wastewater can severely pollute aquatic environments and waste water resources. With increasingly stringent environmental regulations and the growing popularity of water recycling, the reuse of treated industrial wastewater has become a crucial trend in the industry. Reverse osmosis membrane technology, due to its high purification efficiency and excellent treatment effect, is widely used in industrial wastewater treatment and reuse systems. To improve treatment efficiency, industrial wastewater typically undergoes pretreatment processes such as filtration and chemical reactions before entering the reverse osmosis membrane. This removes impurities and some pollutants, preventing clogging or damage to the reverse osmosis membrane and extending its lifespan.
[0003] In existing industrial wastewater treatment and reuse systems, the pretreatment stage relies heavily on independent drive equipment for feeding and wastewater mixing. This not only increases energy consumption but also requires additional control devices to coordinate the operation of each stage, resulting in a complex system structure and high operating costs. Furthermore, the feeding rate is difficult to adaptively adjust based on the influent flow rate. A high influent flow rate can lead to insufficient reagents and inadequate treatment, while a low flow rate can result in excessive reagents, causing waste and secondary pollution. In addition, the filter components in the pretreatment stage are mostly fixed installations, making disassembly and cleaning inconvenient. Long-term use can lead to impurity buildup, affecting filtration efficiency and reducing the purification effect of subsequent reverse osmosis membranes, thus failing to meet the requirements for efficient industrial wastewater treatment and reuse.

[0006] Compared with the prior art, the beneficial effects of the present invention are: 1. This system utilizes the water inlet drive component to drive the water impeller to rotate using the impact force of water flow, which in turn synchronously drives the mixing impeller and the adaptive feeding component to operate. There is no need to set up separate drive equipment for mixing and feeding. The coordinated operation of water inlet, mixing and feeding is achieved through mechanical linkage structure, eliminating the need for complex control devices to coordinate each link, simplifying the overall system structure, reducing equipment investment and maintenance costs, and solving the problems of high energy consumption and complex structure caused by existing systems relying on independent drive equipment.
[0007] 2. The adaptive feeding component, through the linkage of bevel gears, rotating shafts, actuating rods, and arc-shaped retaining rings, combined with the resetting action of torsion springs, automatically matches the feeding amount with the influent flow rate. The higher the influent flow rate, the stronger the water flow impact force, the higher the speed of the impeller and rotating shafts, and the higher the frequency at which the actuating rod drives the arc-shaped retaining ring to deflect, thus increasing the feeding amount. When the influent flow rate decreases, the speed of each component decreases, and the feeding amount decreases synchronously, avoiding insufficient or excessive reagents. This ensures effective wastewater treatment, saves reagent usage, eliminates secondary pollution, and solves the problem of the existing system's inability to adaptively adjust the feeding amount.
[0008] 3. The filter assembly uses a filter plate that slides inside the support shell and is fixed by a fixing plate and bolts. When impurities accumulate on the filter plate surface and affect filtration efficiency, the bolts on the fixing plate can be directly removed to take the filter plate out of the support shell for cleaning or replacement. This operation is convenient and efficient. It effectively removes accumulated impurities, prevents a decrease in filtration efficiency, ensures stable filtration performance in the pretreatment stage, provides high-quality feed water for subsequent reverse osmosis membrane treatment, extends the service life of the reverse osmosis membrane, and solves the problems of inconvenient installation, disassembly, and cleaning of filter components in existing systems.

[0019] Specifically, the third rotating shaft 42 is rotatably connected to the support shell 32, the actuating rod 43 is fixedly connected to one end of the third rotating shaft 42, the actuating rod 43 is L-shaped, the lower side of the discharge cylinder 45 is fitted to the inner side of the arc-shaped retaining ring 49, two sets of arc-shaped retaining rings 49 are provided and symmetrically arranged, the fourth rotating shaft 46 is provided in two sets and symmetrically arranged on the two sets of arc-shaped retaining rings 49, the circular gear 47 is provided in two sets and symmetrically meshed, and the fourth rotating shaft 46 is rotatably connected to the discharge cylinder 45.
[0020] In this embodiment, the torsion spring 410 is sleeved on the end of another set of fourth rotating shafts 46 away from the spur gear 47. The two ends of the torsion spring 410 are respectively fixedly connected to the side of the discharge cylinder 45 away from the spur gear 47 and the inner side of the arc-shaped retaining ring 49 away from the spur gear 47. The discharge plate 411 is located directly below the arc-shaped retaining ring 49. The end of the discharge pipe 412 away from the discharge plate 411 is inserted through the processing barrel 2. The driven drive rod 48 is L-shaped, and the actuating rod 43 slides against the driven drive rod 48.
[0021] Specifically, the filter assembly 5 includes a filter plate 51 that is slidably disposed inside the support housing 32, and a fixing plate 52 is provided on one side of the filter plate 51, and the fixing plate 52 is installed on one side of the support housing 32 by bolts.
[0022] Working principle or structural principle: Industrial wastewater is transported to the interior of the support shell 32 through the inlet pipe 31. The water flow impacts the impeller 34 on the first rotating shaft 33 inside the support shell 32 from top to bottom. The impact force of the water flow drives the impeller 34 to rotate, which in turn drives the first rotating shaft 33 to rotate synchronously. When the first rotating shaft 33 rotates, the first bevel gear 36 at one end rotates accordingly. Since the first bevel gear 36 meshes with the second bevel gear 37, it drives the second bevel gear 37 and the second rotating shaft 38 connected to it to rotate. The end of the second rotating shaft 38 that extends to the inside of the treatment tank 2 drives the mixing impeller 39 to rotate, preparing for the subsequent mixing of wastewater and reagents. Simultaneously, the side of the second bevel gear 37 away from the first bevel gear 36 meshes with the third bevel gear 41. When the second bevel gear 37 rotates, it drives the third bevel gear 41 and the third rotating shaft 42 to rotate. The L-shaped actuating rod 43 at one end of the third rotating shaft 42 rotates together. During the rotation of the actuating rod 43, it slides against the driven driving rod 48, causing the driven driving rod 48 to rotate in conjunction with the fourth rotating shaft 46. When the fourth rotating shaft 46 rotates, the arc-shaped retaining ring 49 on it deflects synchronously, causing the medicine in the container 44 to fall through the discharge cylinder 45 into the discharge tray 411 below, and then be transported to the processing tank 2 through the discharge pipe 412. The torsion spring 410 will drive the fourth rotating shaft 46 and the arc-shaped retaining ring 49 to reset after the actuating rod 43 disengages from the driven driving rod 48, realizing adaptive intermittent feeding. Wastewater, conveyed through inlet pipe 31, impacts impeller 34 and flows through drain outlet 35 on the lower side of support shell 32 to filter plate 51 of filter assembly 5. Filter plate 51 performs preliminary filtration of impurities in the wastewater. The filtered wastewater then enters treatment tank 2 through outlet pipe on the lower side of support shell 32. The wastewater entering treatment tank 2 is thoroughly mixed with the reagents conveyed by adaptive feeding assembly 4 under the rotational stirring action of mixing impeller 39, completing the reagent reaction treatment. Subsequently, it can enter the reverse osmosis membrane treatment stage for water reuse. The filter plate 51 of filter assembly 5 can be removed from the inside of support shell 32 by removing the bolts on fixing plate 52 for cleaning or replacement, ensuring the stability of filtration effect.
