Description

Technical Field

[0001] The present application relates to the technical field of wastewater treatment, and in particular to a reverse osmosis treatment device for industrial wastewater. Background Art

[0002] Industrial wastewater refers to wastewater generated in the process of industrial production. These wastewaters may contain various harmful substances, such as heavy metals, organic pollutants, inorganic salts, suspended solids, acid-base substances, etc. The sources of industrial wastewater are very wide, including but not limited to chemical, pharmaceutical, metallurgical, textile, papermaking, food processing and other industries. Due to the complex composition of industrial wastewater and the difficulty in treatment, if it is directly discharged without proper treatment, it will cause serious pollution to the environment and endanger human health and ecological balance.

[0003] Physical treatment is the initial step in industrial wastewater treatment. It mainly removes suspended solids and some soluble substances in wastewater through sedimentation, flotation and filtration. Sedimentation uses gravity to settle solid particles, while flotation uses bubbles to bring solid or liquid particles to the water surface. Filtration removes tiny particles through media such as sand filtration or activated carbon.

[0004] For example, an industrial waste gas and wastewater treatment device with a publication number of CN118286790A relates to the technical field of waste gas and wastewater treatment. The prior art includes a treatment body; an air inlet pipe is fixedly connected to one side of the outside of the treatment body; a water pump is provided to extract the mixed drug wastewater at the water storage tank, and the mixed drug wastewater is circulated and sprayed at multiple atomizing nozzles to reduce the waste of wastewater resources; a filter screen is fixed at the front end of multiple atomizing nozzles, and the filter screen can filter a large amount of impurities in the waste gas to improve the purification effect of the waste gas; two heat absorbing plates are used in conjunction with the filter screen to absorb the heat in the waste gas, and the heat is transferred to the water storage tank to heat the wastewater, thereby reducing the residual bacteria in the wastewater; the rotating rod is rotated in conjunction with the scraper plate, and the scraper plate is attached to the outer wall of the filter screen plate to scrape impurities, thereby reducing the residual impurities on the outer wall of the filter screen plate; a DC nozzle is used to spray the circulated mixed wastewater, and the DC flushes the rotating disk to make it rotate, thereby synchronously driving the rotating rod to rotate.

[0005] However, the above-mentioned prior art still has some defects when it comes to wastewater treatment:

[0006] 1. The above-mentioned prior art uses a water pump to extract the mixed drug wastewater from the water storage tank, which is circulated and sprayed by multiple atomizing nozzles, and uses a filter screen to filter a large amount of impurities in the exhaust gas to improve the purification effect of the exhaust gas. Two heat absorbing plates are used in conjunction with the filter screen to absorb the heat in the exhaust gas, and the heat is transferred to the water storage tank to heat the wastewater and reduce the residual bacteria in the wastewater. However, in actual applications, the wastewater contains a large amount of impurities, which will clog the atomizing nozzle, affecting the continuity and stability of the wastewater treatment, and may also require frequent maintenance and replacement of the nozzle.

[0007] 2. Due to the continuous spraying of the atomizing nozzle, the atomized drug and wastewater mixture does not generate heat. Instead, it will take away more heat due to evaporation during the atomization process, which not only affects the heating effect of the wastewater, but may also cause drug residue problems and affect the quality and safety of wastewater treatment.

[0008] Based on this, and according to the above-mentioned viewpoints, there is still room for improvement in the existing technology for industrial wastewater treatment. Summary of the invention

DETAILED DESCRIPTION

[0045] The following is combined with Figures 1 to 10 This application is described in further detail.

[0046] The embodiment of the present application discloses a reverse osmosis treatment device for industrial wastewater, which performs a filtration on the wastewater entering the filter, performs a secondary filtration on the filtered wastewater through reverse osmosis treatment, discharges the filtered wastewater, and transports the impurities and sediments in the wastewater back to the primary filtration, thereby performing a circulation filtration and improving the filtration effect.

[0047] Embodiment 1:

[0048] Reference Figure 1 and Figure 2 A reverse osmosis treatment device for industrial wastewater comprises a filter tank 1, and a sewage discharge cylinder 2 embedded in the filter tank 1 is arranged at the lower end of the filter tank 1.

[0049] When treating industrial wastewater, the wastewater is first transported into the filter tank 1 through the water inlet pipe 11 set at one end of the filter tank 1. The wastewater entering the filter tank 1 will be filtered by the filter 3 set in the filter tank 1, and then the circulator 4 set on the filter tank 1 is driven by the driving member 6 to work. The circulator 4 performs secondary filtration on the filtered wastewater through reverse osmosis treatment, discharges the filtered wastewater, and transports impurities and sediments in the wastewater back to the filter tank 1, thereby performing circulation filtration to improve the filtering effect.

[0050] While the filter 3 is filtering, impurities and sediments in the wastewater in the filter tank 1 will be precipitated into the sewage tube 2 through the guide port 22 opened on the sewage tube 2 and located inside the filter tank 1, and then discharged through the outlet pipe 21 set by the one-way valve at the end of the sewage tube 2 away from the water inlet pipe 11 for further filtration, and then the filtered wastewater is transported back to the filter tank 1 for circulation filtration, so as to further improve the filtering effect.

[0051] During the continuous filtering process, the waste water in the filter tank 1 is continuously reduced due to being filtered. At this time, the water replenisher 5 arranged on one side of the filter tank 1 will replenish the waste water into the filter tank 1 for continuous filtering.

[0052] Reference Figures 2 to 4 Specifically, the filter 3 includes a plurality of support frames 31 arranged in the filter tank 1, and a notch 312 corresponding to the sewage barrel 2 is arranged on the support frame 31. The wastewater entering the filter tank 1 through the water inlet pipe 11 will pass through the reverse osmosis membrane 311 arranged on the support frame 31 in sequence. The reverse osmosis membrane 311 is highly selective, allowing water molecules to pass through while blocking most dissolved solids, organic matter and microorganisms.

[0053] Most of the impurities in the wastewater will be blocked by the reverse osmosis membrane 311, and the reverse osmosis membrane 311 is detachably connected to the support frame 31, which is easy to disassemble and maintain.

[0054] A support sealing plate 32 is provided in the sewage barrel 2, and the support sealing plate 32 is located in a notch 312 on a support frame 31 close to the water outlet pipe 21. The support frame 31 close to the water outlet pipe 21 and the support sealing plate 32 in the notch 312 separate the filter tank 1 into a drainage chamber 33 and a sewage chamber 34.

[0055] Wastewater enters the sewage chamber 34 from the water inlet pipe 11 and contacts the reverse osmosis membrane 311, and the impurities therein are blocked by the reverse osmosis membrane 311. The water in the wastewater enters the drainage chamber 33 after passing through the several reverse osmosis membranes 311 in the drainage chamber 33; then, through the existing motor driving technology, the transmission shaft 35 rotating and passing between the sewage barrel 2 and the support sealing plate 32 is driven to rotate, and the rotating transmission shaft 35 will drive the spiral blade 1 351 and the spiral blade 2 352 respectively arranged on the two ends of the support sealing plate 32 on the transmission shaft 35, and the spiral blade 1 351 and the spiral blade 2 352 are both located in the sewage barrel 2.

[0056] A drain frame 36 is provided on the lower side of the filter tank 1. Impurities precipitated in the sewage tube 2 in the sewage chamber 34 will be transported by the rotating spiral blade 351 to the connecting pipe 361 provided between one end of the sewage chamber 34 and the drain frame 36. The precipitated impurities and part of the waste water will pass through the connecting pipe 361 and enter the drain frame 36. The impurities in the drain frame 36 will be blocked by the detachable filter membrane 363 provided at the bottom of the drain frame 36, and the moisture in the waste water will pass through the filter membrane 363 and a plurality of drain holes 362 opened at the bottom of the drain frame 36, and then enter the water collecting frame 37 provided at the lower end of the drain frame 36 and located at the lower side of the drain hole 362.

[0057] The water flow in the water collecting frame 37 will pass through the reflux pipe 371 connected to the sewage chamber 34 through a one-way valve set on the water collecting frame 37, and then flow back to the sewage chamber 34 to continue the osmotic filtration; in this process, the impurities filtered in the sewage chamber 34 will continuously enter the drain frame 36, and then be blocked by the filter membrane 363 to ensure that the impurities stay in the drain frame 36, so as to reduce the amount of impurity sedimentation in the sewage chamber 34.

[0058] The spiral blade 2 352 will transport the water in the drainage chamber 33 that has passed through osmosis filtration to the outlet pipe 21, and transport the filtered wastewater to the circulator 4 through the outlet pipe 21. The circulator 4 performs secondary filtration on the filtered wastewater through reverse osmosis treatment, discharges the filtered wastewater, and transports the impurities and sediment in the wastewater back to the filter tank 1, thereby performing circulating filtration, which not only improves the wastewater treatment efficiency, but also ensures the effective separation and collection of impurities through the arrangement of the drain frame 36 and the filter membrane 363, thereby reducing the impurity sedimentation residue in the sewage chamber 34 and improving the filtering effect.

[0059] The drain frame 36 is detachably connected to the filter tank 1 for easy maintenance and cleaning.

[0060] Reference Figures 5 to 7Specifically, the circulator 4 includes a circulation tank 12 arranged on the filter tank 1 through a bracket, a rotating drum 42 is rotatably penetrated in the circulation tank 12, a circulation cavity 41 is formed between the rotating drum 42 and the circulation tank 12, and the water outlet pipe 21 is connected to the circulation cavity 41, and a guide cylinder 44 embedded in the circulation tank 12 is arranged on the lower side of the circulation tank 12.

[0061] After the spiral blade 2 352 transports the osmotic filtered water to the outlet pipe 21, the filtered wastewater will enter the circulation chamber 41 through the outlet pipe 21. As the water flow continues to enter the circulation chamber 41, the water flow will pass through a number of filter holes 421 opened on the rotating drum 42 and located in the circulation tank 12, and then contact the water filter membrane 43 located in the circulation tank 12 set on the rotating drum 42. At this time, the wastewater will be further filtered, and then enter the rotating drum 42, and then the filtered wastewater will be discharged through the discharge pipe 47 set at one end of the rotating drum 42.

[0062] The impurities therein will be blocked and remain in the circulation chamber 41 , and the blocked impurities will enter the guide tube 44 through the communication port 441 opened on the guide tube 44 and located in the circulation chamber 41 .

[0063] At the same time, the driving member 6 will drive the driving shaft 45 coaxial with the guide cylinder 44 to rotate, and the rotating driving shaft 45 will drive the auger blade 451 set on the driving shaft 45 to rotate together. The auger blade 451 will transport the wastewater in the circulation chamber 41 to the connecting pipe 46 set on the guide cylinder 44 through the one-way valve, and transport the impurities and wastewater in the circulation chamber 41 to the sewage chamber 34 through the connecting pipe 46 connected to the sewage chamber 34, thereby realizing circulation filtration.

[0064] Among them, a scraper 48 is provided in the circulation chamber 41, which contacts the outer side of the drum 42. During this process, the driving member 6 will also drive the drum 42 to rotate. During the rotation of the drum 42, the scraper 48 will scrape off the impurities attached to the drum 42, so that the impurities enter the circulation chamber 41 and then return to the sewage chamber 34 from the connecting pipe 46 for circulation filtration.

[0065] At the same time, the rotating drum 42 will drive the reciprocating spiral groove 422 provided on the drum 42 to rotate synchronously. A scraper 49 slidably connected to the scraper 48 is slidably provided in the circulation chamber 41. The scraper 49 moves back and forth in the circulation chamber 41 through the protrusion 491 corresponding to the reciprocating spiral groove 422 provided thereon. The scraper 49 will scrape off the impurities attached to the drum 42, the circulation tank 12 and the scraper 48. At the same time, the scraper 49 can also disturb the waste water in the circulation chamber 41 to prevent impurities from forming a stable deposition layer on the water filter membrane 43, thereby reducing the blockage of the water filter membrane 43, which helps to maintain the filtration efficiency of the water filter membrane 43 and extend its service life.

[0066] Through disturbance, impurities in the wastewater can be distributed more evenly, which helps to improve the uniformity of filtration and the overall treatment effect. At the same time, disturbance can promote chemical reactions in the wastewater, such as redox reactions, which helps to further remove organic matter and certain inorganic matter in the wastewater.

[0067] Reference Figure 8 and Fig. 9 Specifically, the water replenisher 5 includes a water replenishment pipe 51 arranged on the water inlet pipe 11. When the wastewater is transported to the filter tank 1, the wastewater will pass through the water replenishment pipe 51 and then enter the water inlet pipe 11, and then be transported to the filter tank 1 for circulation filtration.

[0068] A connecting rod 52 is slidably provided on the water supply pipe 51 , a sealing plug 53 located inside the water supply pipe 51 is slidably provided on one end of the connecting rod 52 , and a sliding rod 54 is provided on the other end of the connecting rod 52 .

[0069] When the amount of wastewater in the filter tank 1 reaches a certain level, the wastewater will lift one end of the sliding rod 54 and penetrate the float 55 set behind the filter tank 1, so that the float 55 drives the sliding rod 54 to move upward, and the sliding rod 54 drives the connecting rod 52 to move the sealing plug 53 together, and the sealing plug 53 moves to the upper end of the water inlet pipe 11, thereby blocking the water supply pipe 51 and preventing the wastewater from entering the filter tank 1.

[0070] On the contrary, when the wastewater in the filter tank 1 decreases during continuous circulation and filtration, the float 55 will move downward as the water level drops. At the same time, the float 55 will drive the sliding rod 54 to move together. The sliding rod 54 will drive the connecting rod 52 to move the sealing plug 53 to the lower side of the water inlet pipe 11, so that the water replenishment pipe 51 is connected to the water inlet pipe 11, so that the wastewater enters the filter tank 1 from the water inlet pipe 11 for replenishment.

[0071] When the connecting rod 52 moves downward, it will drive the limiting ring 56 set on the connecting rod 52 to move downward together, and compress the return spring 57 set between the limiting ring 56 and the water supply pipe 51, so that the sealing plug 53 blocks the water supply pipe 51 and prevents waste water from entering the filter tank 1; conversely, when the connecting rod 52 moves upward, it will also drive the limiting ring 56 set on the connecting rod 52, and release the compressed return spring 57 at the same time. The return spring 57 balances the moving force of the connecting rod 52, the sliding rod 54 and the float 55, ensuring the quick response and stable operation of the float 55 when the water level changes.

[0072] Among them, the sliding rod 54 is provided with an adjusting screw 58 threadedly connected thereto, and the float 55 is arranged at one end of the adjusting screw 58. The position of the float 55 is changed by rotating the adjusting screw 58, thereby controlling the timing and amount of water replenishment, so that the water replenisher 5 can adapt to different wastewater treatment conditions and requirements. The user can flexibly adjust the working state of the water replenisher 5 according to the flow rate of wastewater, the volume of the filter tank 1 and the water level changes during the treatment process, which helps to improve the operating efficiency and treatment effect of the system.

[0073] Reference Fig.10 The driving member 6 includes a rotating gear 61 arranged on one side of the rotating drum 42 , and a transmission gear 62 meshing with the rotating gear 61 is disposed on the driving shaft 45 .

[0074] Start the driving motor 63 set on the filter tank 1 through the bracket, the driving motor 63 will drive the driving gear 64 set on its driving end to rotate, the rotating driving gear 64 will drive the transmission gear 62 to rotate through meshing, the rotating transmission gear 62 will drive the driving shaft 45 to rotate, thereby driving the auger blade 451 to rotate; at the same time, the rotating transmission gear 62 will drive the rotating gear 61 through meshing, so that the rotating drum 42 rotates and drives the scraper 49 to reciprocate in the circulation chamber 41.

[0075] Embodiment 2:

[0076] Reference Fig.10 On the basis of the first embodiment, the driving shaft 45 is connected to the transmission shaft 35 by means of a belt drive. When the driving shaft 45 rotates, the transmission shaft 35 is driven to rotate together by means of the belt drive, thereby driving the spiral blade 1 351 and the spiral blade 2 352 to rotate.

[0077] The implementation principle of the present invention is:

[0078] (1): When treating industrial wastewater, the wastewater is first transported into the filter tank 1 through the water inlet pipe 11 provided at one end of the filter tank 1.

[0079] (2): Wastewater enters the sewage chamber 34 from the water inlet pipe 11 and contacts the reverse osmosis membrane 311 . Impurities in the wastewater are blocked by the reverse osmosis membrane 311 . Water in the wastewater enters the drainage chamber 33 after passing through the reverse osmosis membranes 311 in the drainage chamber 33 .

[0080] (3): Then, the driving member 6 drives the transmission shaft 35 that is rotatably arranged between the sewage discharge barrel 2 and the supporting sealing plate 32 to rotate, and the rotating transmission shaft 35 drives the spiral blade 1 351 and the spiral blade 2 352 on the transmission shaft 35.

[0081] (4): The rotating spiral blade 351 is transported to the connecting pipe 361 set between one end of the sewage chamber 34 and the drain frame 36. The precipitated impurities and part of the wastewater will pass through the connecting pipe 361 and enter the drain frame 36. The impurities in the drain frame 36 will be blocked by the detachable filter membrane 363 set at the bottom of the drain frame 36, while the moisture in the wastewater will pass through the filter membrane 363 and a plurality of drain holes 362 opened at the bottom of the drain frame 36, and then enter the water collecting frame 37 set at the lower end of the drain frame 36 and located at the lower side of the drain hole 362.

[0082] (5): The spiral blade 2 352 will transport the water in the drainage chamber 33 that has passed through osmosis filtration to the outlet pipe 21, and the filtered wastewater will be transported to the circulator 4 through the outlet pipe 21. The circulator 4 will perform secondary filtration on the filtered wastewater through reverse osmosis treatment, discharge the filtered wastewater, and transport the impurities and sediments in the wastewater back to the filter tank 1, thereby performing circulating filtration. This not only improves the wastewater treatment efficiency, but also ensures the effective separation and collection of impurities through the arrangement of the drain frame 36 and the filter membrane 363, thereby reducing the amount of impurity sediment in the sewage chamber 34 and improving the filtering effect.

[0083] (6): After the spiral blade 2 352 delivers the water that has passed through the osmotic filtration to the outlet pipe 21, the filtered wastewater will enter the circulation chamber 41 through the outlet pipe 21. As the water flow continues to enter the circulation chamber 41, the water flow will pass through a number of filter holes 421 located in the circulation tank 12 opened on the rotating drum 42, and then contact the water filter membrane 43 located in the circulation tank 12 set on the rotating drum 42. At this time, the wastewater will be further filtered, and then enter the rotating drum 42, and then the filtered wastewater will be discharged through the discharge pipe 47 set at one end of the rotating drum 42.

[0084] The impurities therein will be blocked and remain in the circulation chamber 41 , and the blocked impurities will enter the guide tube 44 through the communication port 441 opened on the guide tube 44 and located in the circulation chamber 41 .

[0085] (7): At the same time, the driving member 6 will drive the driving shaft 45 coaxially arranged on the guide cylinder 44 to rotate, and the rotating driving shaft 45 will drive the auger blade 451 arranged on the driving shaft 45 to rotate together. The auger blade 451 will transport the wastewater in the circulation chamber 41 to the connecting pipe 46 arranged on the guide cylinder 44 through the one-way valve, and transport the impurities and wastewater in the circulation chamber 41 to the sewage chamber 34 through the connecting pipe 46 connected to the sewage chamber 34, thereby realizing circulation filtration.

[0086] (8): The rotating drum 42 will drive the reciprocating spiral groove 422 provided on the drum 42 to rotate synchronously. A scraper 49 slidably connected to the scraper 48 is slidably provided in the circulation chamber 41. The scraper 49 reciprocates in the circulation chamber 41 through the protrusion 491 provided thereon corresponding to the reciprocating spiral groove 422. The scraper 49 will scrape off the impurities attached to the drum 42, the circulation tank 12 and the scraper 48. At the same time, the scraper 49 can also disturb the wastewater in the circulation chamber 41 to prevent the impurities from forming a stable deposition layer on the water filter membrane 43, thereby reducing the blockage of the water filter membrane 43, which helps to maintain the filtration efficiency of the water filter membrane 43 and extend its service life.

[0087] (9): Disturbance can make the impurities in the wastewater more evenly distributed, which helps to improve the uniformity of filtration and the overall treatment effect. At the same time, disturbance can promote chemical reactions in the wastewater, such as redox reactions, which helps to further remove organic matter and certain inorganic matter in the wastewater.

[0088] (10): The sliding rod 54 is provided with an adjusting screw 58 threadedly connected thereto, and a float 55 is arranged at one end of the adjusting screw 58.
