Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater recycling and reuse treatment device. Background Technology

[0002] In machining, metal cutting, parts cleaning, and equipment maintenance, wastewater containing iron filings, iron powder, steel shavings, cutting fluid, emulsified oil, suspended particles, and cleaning agents is typically generated. For this type of machining wastewater, screens or filters are generally used to intercept larger particles, followed by sedimentation, oil separation, flotation, flocculation, adsorption, or multi-stage filtration to remove oil, suspended solids, and some dissolved pollutants. For wastewater containing a large amount of magnetic particles such as iron filings and steel shavings, magnetic rods, magnetic rollers, or magnetic separators are also used to remove metal particles. The treated water can be reused for rinsing, cooling, spraying, or other industrial auxiliary water applications, depending on its quality, to reduce fresh water consumption and wastewater discharge.

[0003] However, existing wastewater treatment equipment for machining still has certain shortcomings in practical use: ordinary filter screens are prone to clogging after intercepting iron filings, steel filings, and suspended particles, requiring frequent shutdowns for cleaning and affecting continuous treatment efficiency; magnetic separation structures are mostly set up separately, and if the adsorbed metal particles cannot be desorbed and collected in time, they can easily fall back into the water or cause wear on subsequent components; at the same time, when emulsified oil, sludge, demulsified flocs, and fine suspended solids are mixed with fine metal powder, it is difficult for a single sedimentation or filtration method to remove them sufficiently, easily causing excessive load on the end filter media and fluctuations in effluent quality. In addition, there is a lack of effective linkage between processes such as filtration, magnetic adsorption, air flotation, and sludge discharge, often requiring multiple independent drives or manual assistance for cleaning, which not only increases equipment operation and maintenance costs but also reduces the stability of the wastewater recycling process.

[0010] Preferably, the bubble-pressing assembly includes a fixed plate fixedly connected to the inner surface of the second processing chamber from left to right.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, through the sequential coordination of various components, allows wastewater to flow sequentially within the treatment tank according to the arrangement of four treatment chambers. First, the first filter component intercepts iron filings, steel filings, large suspended particles, and larger solid impurities in the wastewater, while simultaneously maintaining water flow in the filtration area. Then, the metal adsorption component continuously adsorbs, carries out, desorbs, and collects magnetic metal particles such as iron powder and steel filings entering the subsequent water body, reducing the possibility of metal impurities re-mixing into the water body. Next, the foaming component releases uniform microbubbles into the wastewater, causing oil sludge, demulsified flocs, fine iron powder oil clumps, and fine suspended solids to float to the surface and be scraped away. Finally, the second filter component performs end-of-pipe purification of residual fine suspended solids, emulsified oil droplets, and organic pollutants after the air flotation treatment. The entire process achieves continuous and synergistic treatment of primary filtration, magnetic adsorption impurity removal, air flotation oil and slag removal, and fine filtration purification, reducing the frequency of manual cleaning, lowering the risk of subsequent filter blockage and impurity backflow, and improving the stability, continuous operation capability, and quality of recycled water in wastewater reuse treatment.

[0015] 2. This invention, through the linkage of a motor, rotating shaft, belt drive assembly 1, and reciprocating rod, enables scraper 1 and cleaning brush to continuously clean the filter screen and nylon filter screen respectively, thereby reducing impurity adhesion and filter pore blockage, ensuring stable water flow capacity of primary filtration. Subsequently, the cooperation of rotating inner cylinder and electromagnetic plate can achieve continuous separation of magnetic metal particles, and the metal particles are collected in a concentrated manner with the help of sliding block, connecting rod and scraper 2, reducing the risk of metal particle backflow and wear of subsequent components. At the same time, the air bladder is squeezed to improve the uniformity of microbubble release, so that oil sludge, demulsified flocs and fine suspended solids can float and separate more fully. Then, with the help of push rod, fixed rod and push block, the scum is discharged in time, reducing the secondary mixing of pollutants into the water body, and improving the continuity, stability and quality of recycled water in the overall wastewater reuse treatment.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] Example 1: A wastewater recycling and reuse treatment device, see [link / reference] Figure 1 and Figure 2 The system includes a treatment chamber 1, which contains four treatment compartments 11. The two treatment compartments on the left are each provided with an overflow port 12 at their right ends. The third treatment compartment 11 from the left is provided with a vertically distributed drain port 13 and an electric valve 14 at its right end. The first treatment compartment 11 from the left is provided with a filter assembly 2. The second treatment compartment 11 from the left is provided with a metal adsorption assembly 3. The third treatment compartment 11 from the left is provided with a foam depressor assembly 4. The fourth treatment compartment 11 from the left is provided with a filter assembly 5.

[0020] The overflow outlet 12 located in the first treatment chamber 11 is higher than the right overflow outlet 12 located in the second treatment chamber 11, so that the water will only overflow from left to right.

[0021] In the operation of this embodiment, through the sequential cooperation of various components, the sewage can flow step by step in the treatment tank 1 according to the arrangement of four treatment chambers 11. First, the filter component 2 is used to initially intercept iron filings, steel filings, large particulate suspended solids and larger solid impurities in the sewage, while maintaining the water flow state of the filtration area. Then, the metal adsorption component 3 continuously adsorbs, carries out, desorbs and collects magnetic metal particles such as iron powder and steel filings that enter the subsequent water body, reducing the possibility of metal impurities being re-mixed into the water body. Then, the foaming component 4 is driven to release uniform microbubbles into the sewage, causing oil sludge, demulsified flocs, fine iron powder oil clumps and fine suspended solids to float and be scraped away. Finally, the filter component 5 is used to perform terminal purification of residual fine suspended solids, emulsified oil droplets, organic pollutants and a small amount of metal ions after the air flotation treatment. The whole process realizes continuous and synergistic treatment of primary filtration, magnetic adsorption impurity removal, air flotation oil and slag removal and fine filtration purification, reducing the frequency of manual cleaning, reducing the risk of subsequent filter blockage and impurity backflow, and improving the stability, continuous operation capability and quality of recycled water in sewage reuse treatment.

[0022] For further details, please refer to [link / reference]. Figure 1 - Figure 9 The filter assembly 2 includes four support frames 21 fixedly connected to the inner surface of the first processing chamber 11 from left to right. A filter screen 22 is installed between the four support frames 21. A motor 23 is fixedly installed at the left end of the processing box 1. A rotating shaft 24 is fixedly connected to the output end of the motor 23. A belt drive assembly 25 is fixedly connected to the outer surface of the rotating shaft 24. A reciprocating rod 26 is fixedly connected to the end of the belt drive assembly 25 away from the rotating shaft 24. A scraper 27 is slidably connected to the outer surface of the reciprocating rod 26. The side surface of the scraper 27 is slidably connected to the filter screen 22. A dirt collection chamber 28 is provided on the lower side of both the left and right ends of the filter screen 22.

[0023] Furthermore, the belt drive assembly 25 is a belt drive mechanism in the prior art, consisting of two pulleys and a belt; The connection between the reciprocating rod 26 and the scraper 27 is a ball screw mechanism in the prior art. The rotation of the reciprocating rod 26 can drive the scraper 27 to move back and forth. The reciprocating rod 26 is divided into two sections, each of which is provided with an independent forward and reverse spiral and a reversing groove. The grooves of the two sections are not connected.

[0024] Specifically, the starting motor 23 drives the rotating shaft 24 to rotate, and the sewage directly enters the filter screen 22 from the leftmost end of the treatment tank 1. After passing through the filter screen 22, iron filings, steel filings, large suspended particles, and larger solid impurities in the sewage are initially intercepted, preventing large particles from directly entering the subsequent treatment area and causing blockage or wear. This helps to reduce the load on the subsequent treatment units. Simultaneously, when the rotating shaft 24 rotates, it drives the reciprocating rod 26 to rotate through the belt drive assembly 25. The rotation of the reciprocating rod 26 drives the scraper 27 to move back and forth on the inner surface of the filter screen 22, which can continuously scrape and push the impurities intercepted on the lower side of the filter screen 22 and push them into the two side collection chambers 28, so that the filtration area maintains a good water flow state, reduces the impact of impurity accumulation on filtration efficiency, and thus improves the continuous operation capability of the primary filtration process.

[0025] Furthermore, scraper 27 is slidably connected to support frame 21, and support frame 21 can limit scraper 27 so that scraper 27 can only move back and forth in parallel.

[0026] Furthermore, a through groove 29 is provided at the upper end of the filter screen 22, a connecting frame 210 is fixedly connected to the upper end of the scraper 27, a cleaning brush 211 is provided at the lower end of the connecting frame 210, and a nylon filter screen 212 is provided on the inner surface of the first treatment chamber 11 from left to right, and the cleaning brush 211 is slidably connected to the nylon filter screen 212.

[0027] Furthermore, the wastewater passes through filter screen 22 and then through nylon filter screen 212. Nylon filter screen 212 can further filter the wastewater after the initial treatment by filter screen 22, intercepting finer iron powder, small steel filings and larger oil flocs in the wastewater, thereby further reducing the content of solid impurities in the water body to be treated.

[0028] Synchronously, the cleaning brush 211 moves back and forth along with the connecting frame 210, so that the cleaning brush 211 cleans the nylon filter screen 212, reduces filter hole clogging and filter surface adhesion, and improves the water flow stability of the filter plate.

[0029] Furthermore, the metal adsorption assembly 3 includes a rotating outer cylinder 31 fixedly connected to the inner surface of the second processing chamber 11 from left to right, a belt drive assembly 32 fixedly connected to the right end of the rotating shaft 24, a rotating shaft 33 fixedly connected to the end of the belt drive assembly 32 away from the rotating shaft 24, a rotating inner cylinder 34 fixedly connected to the right end of the rotating shaft 33, and an electromagnetic plate 35 installed on the lower side of the outer surface of the rotating inner cylinder 34.

[0030] Furthermore, the metal adsorption assembly 3 also includes a sliding block 36 that is slidably connected to the outer surface of the reciprocating rod 26, a limit rod 37 that is slidably connected to the inner surface of the sliding block 36, a connecting rod 38 that is fixedly connected to the lower end of the sliding block 36, and a scraper 39 that is fixedly connected to the lower end of the connecting rod 38.

[0031] The rotating outer cylinder 31 mentioned above is made of non-magnetic, corrosion-resistant material, preferably austenitic stainless steel, so that the magnetic field generated by the electromagnetic plate 35 can pass through the rotating outer cylinder 31 and act on magnetic metal particles such as iron powder and steel filings in the sewage, while avoiding the rotating outer cylinder 31 itself from generating obvious residual magnetism, which would affect the detachment of metal particles in the non-magnetic desorption zone.

[0032] Furthermore, the electromagnetic plate 35 is an arc-shaped plate extending along the axial direction of the rotating outer cylinder 31. Both its inner and outer surfaces are arc-shaped, and its curvature corresponds to the curvature of the inner circumferential wall of the rotating outer cylinder 31. The electromagnetic plate 35 is arranged in an arc shape along the lower part to the upper side of the rotating outer cylinder 31, so that the corresponding outer surface of the rotating outer cylinder 31 forms an arc-shaped magnetic adsorption area. The area not covered by the electromagnetic plate 35 forms a non-magnetic desorption area, so that the magnetic metal particles such as iron powder and steel chips adsorbed on the outer surface of the rotating outer cylinder 31 will detach from the surface of the rotating outer cylinder 31 when rotating to this area.

[0033] Furthermore, the water level slowly rises in the first treatment chamber 11 from left to right, allowing it to enter the second treatment chamber 11 from the overflow port 12 on the left. The water level continues to rise until the lower part of the rotating outer cylinder 31 is immersed in the sewage and the upper part is above the liquid surface, creating an adsorption process in the sewage. Magnetic particles such as iron powder and steel filings are adsorbed onto the outer surface of the rotating outer cylinder 31 and carried out of the liquid surface as the outer cylinder 31 rotates. When the rotating outer cylinder 31 with adsorbed metal particles rotates to the non-magnetic desorption zone not covered by the electromagnetic plate 35, As the metal particles lose their magnetic attraction, the reciprocating rod 26 rotates synchronously, causing the electromagnetic plate 35 to move back and forth on the right half of the reciprocating rod 26. This, in turn, causes the connecting rod 38 and the scraper 39 to move back and forth on the upper side of the rotating outer cylinder 31, pushing the metal particles that have lost their magnetic attraction to the surface of the scraper 39. This makes it difficult for the metal particles to fall back into the water. Through the cooperation of the magnetic adsorption zone and the non-magnetic desorption zone, a continuous cycle of adsorption, carry-out, desorption, and collection can be achieved, reducing the frequency of manual cleaning and improving the automation and stability of the metal particle separation process.

[0034] Furthermore, the bubble-pressing assembly 4 includes a fixed plate 41 fixedly connected to the inner surface of the second processing chamber 11 from left to right. The upper end of the fixed plate 41 is provided with a sliding groove 42. The upper end of the sliding block 36 is fixedly connected with a squeezing plate 43. An airbag 44 is provided at the upper end of the fixed plate 41. The right end of the squeezing plate 43 is fixedly connected to the airbag 44. An air tube 48 is fixedly connected to the right end of the airbag 44. A bubble-pressing mechanism 49 is provided at the end of the air tube 48 away from the airbag 44.

[0035] Furthermore, the bubble pressing assembly 4 also includes a push rod 45 fixedly connected to the right end of the sliding block 36, a fixing rod 46 fixedly connected to the right end of the push rod 45, and a push block 47 fixedly connected to the lower end of the fixing rod 46.

[0036] Furthermore, the foaming mechanism 49 includes a sealed pressure-bearing support layer 493 fixedly connected to the bottom end of the inner surface of the third processing chamber 11 from left to right. A hollow pressure equalizing air chamber 492 is provided at the upper end of the sealed pressure-bearing support layer 493, and a microporous gas release layer 491 is provided at the upper end of the hollow pressure equalizing air chamber 492.

[0037] Specifically, the hollow pressure equalizing chamber 492 diffuses and buffers the gas, creating a more uniform pressure distribution. The microporous gas release layer 491 disperses the gas into the wastewater, forming fine bubbles. The sealed pressure-bearing support layer 493 seals and supports the pressure equalizing chamber, preventing gas leakage from the bottom and ensuring the stability of the gas release structure under water and air pressure. Through the combination of these three layers, the uniformity and stability of bubble release are improved, enhancing the contact effect between bubbles and oil sludge, demulsified flocs, fine suspended solids, and oil clumps.

[0038] When the water flows into the third treatment chamber 11, it first falls onto the foaming mechanism 49, which is conducive to the water body and the microbubble release area to fully contact, enhance the air flotation separation effect, and the microbubbles can adhere to the surface of oil sludge, demulsified flocs, fine iron powder oil clumps and fine suspended matter, reduce their overall settling tendency and promote them to float to the upper scum area, thereby achieving the removal of oil, fine particles and flocculent pollutants by floating.

[0039] Furthermore, as the sliding block 36 moves left and right, it simultaneously drives the extrusion plate 43 to reciprocate and extrude the airbag 44, so that the gas inside the airbag 44 enters the hollow pressure equalization chamber 492 in the bubble compression mechanism 49 through the air pipe 48. Simultaneously, the push rod 45 and the push block 47 move together with the sliding block 36, so that after the microbubbles carry the scum to the upper scum area, the push block 47 can simultaneously scrape and push the scum into the drain outlet 13. The electric valve 14 is located on the lower side of the drain outlet 13, which can avoid the bottom sediment impurities and the upper scum pollution area, reducing the possibility of separated pollutants re-entering the subsequent filtration unit. After the scum on the surface of the drain outlet 13 is scraped off, the electric valve 14 can be opened to allow the sewage to enter the fourth treatment chamber 11.

[0040] Furthermore, the filter assembly 2 5 includes a partition plate 51 fixedly connected to the inner surface of the fourth processing chamber 11 from left to right, and two filter plates 52 are disposed on the lower side of the partition plate 51.

[0041] The two filter plates 52 mentioned above are a polypropylene microporous filter plate and an activated carbon fiber composite filter plate, respectively. The former is used to intercept the fine suspended solids, demulsified floc fragments, fine iron powder oil clumps and small particulate sludge remaining after the air flotation treatment, while the latter is used to remove residual fine suspended solids, emulsified oil droplets, cleaning agent residues, organic pollutants and a small amount of metal ions, so as to improve the cleanliness of the effluent and the stability of recycling, and improve the stability and reliability of the end purification process. Finally, the water flows away from the drain pipe at the lower end of the fourth treatment chamber 11.

[0042] Therefore, in this scheme, the linkage of motor 23, rotating shaft 24, belt drive assembly 25 and reciprocating rod 26 enables scraper 27 and cleaning brush 211 to continuously clean filter screen 22 and nylon filter screen 212 respectively, thereby reducing impurity adhesion and filter hole blockage, ensuring the stable water flow capacity of primary filtration. Subsequently, the cooperation of rotating inner cylinder 34 and electromagnetic plate 35 can realize the continuous separation of magnetic metal particles, and the metal particles are collected in a concentrated manner with the help of sliding block 36, connecting rod 38 and scraper 39, reducing the risk of metal particle backflow and subsequent component wear. At the same time, the air bladder 44 is squeezed to improve the uniformity of microbubble release, so that oil sludge, demulsified flocs and fine suspended solids float to the surface and separate more fully. Then, with the help of push rod 45, fixed rod 46 and push block 47, the scum is discharged in time, reducing the secondary mixing of pollutants into the water body, and improving the continuity, stability and quality of recycled water in the overall wastewater reuse treatment.

[0043] The reclaimed water, after being treated in the above steps, has had large particulate impurities, iron and steel filings, fine suspended solids, oil sludge, emulsified oil, and some organic pollutants removed in sequence. The cleanliness and stability of the water are improved. It can be returned to the production water end through the drain pipe at the lower end of the fourth treatment chamber 11 and reused in industrial auxiliary processes with relatively low water quality requirements, such as equipment cleaning, workpiece washing, floor washing, cooling water replenishment, dust removal spraying, or front-end wastewater dilution. The used water, carrying metal particles, oil, and suspended solids, returns to the treatment tank 1 and continues to be purified in stages through filter assembly 2, metal adsorption assembly 3, foaming assembly 4, and filter assembly 5, thus forming a recycling mode of "wastewater generation - regeneration treatment - reuse in production - collection and treatment again", reducing the consumption of fresh water and the amount of wastewater discharged.

[0044] It should be noted that the specific installation method of the motor 23 and the electromagnetic plate 35, the circuit connection method, and the control method used in this invention are all conventional designs, and will not be described in detail in this invention.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
