Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, in particular to a wastewater recovery and treatment device for antibacterial treatment of polyester fabrics and a treatment method thereof. Background Art

[0002] Antimicrobial treatment of polyester fabrics involves applying an antimicrobial agent to the surface of polyester fibers using a specific technique, aiming to impart antimicrobial and odor-resistant properties. This treatment typically involves blending antimicrobial additives with polyester chips, or applying post-treatments such as coating, resin finishing, or microencapsulation to the polyester fibers. Antimicrobial polyester fabrics effectively remove and inhibit the growth of bacteria, fungi, and mold on the fabric, keeping it clean and preventing bacterial regeneration and proliferation. Their antimicrobial properties primarily work by disrupting bacterial cell walls, causing cell membrane rupture and leakage of cytoplasm, thereby halting microbial metabolism. Antimicrobial polyester fabrics are wash-resistant and maintain their excellent antimicrobial properties even after multiple washes. Furthermore, they are safe and pose no health risks. These fabrics are widely used in clothing, interior textiles, medical textiles, and home textiles, particularly in underwear, casual wear, bedding, and other products requiring high levels of cleanliness and antimicrobial properties.

[0003] After being treated with antibacterial liquid, polyester fabrics need to be cleaned. During cleaning, the antibacterial solution on the fabric will be diluted into the treated water. The components of the antibacterial solution include acids, alkalis, salts, nanoparticles or metal ions. Direct discharge of wastewater will cause environmental pollution and waste of resources. For example, a Chinese patent with announcement number CN113173673B discloses a method and equipment for recycling wastewater from antibacterial treatment of down jacket fabrics. During the wastewater recycling process, the equipment directly uses activated carbon for adsorption and filtration, which causes large and small impurities to easily directly clog the activated carbon filter element, and the activated carbon on the blades of the rotating shaft is also difficult to replace and maintain.

A stirring motor is fixedly installed at the upper end of the box cover, and the agitator at the output end of the stirring motor extends into the interior of the separation box.

[0014] A method for recycling wastewater from antibacterial treatment of polyester fabrics, comprising the following steps:

[0015] S1. First, the wastewater after antibacterial treatment of polyester fabrics is discharged into the pretreatment box. Then, the impurities are filtered out through the filter grid at the top of the pretreatment box. Then, under the action of the inclined water guide plate of the pretreatment box, the wastewater is discharged into the inclined filter screen through the gap between the inclined water guide plate and the pretreatment box. The wastewater flows downward from the high part of the inclined filter screen to the low part;

[0016] S2. The wastewater after being filtered by the oblique filter directly enters the bottom of the pretreatment box. At the same time, part of the filtered impurities and wastewater flow along the lower part of the oblique filter and through the rectangular holes on the pretreatment box through the upper hole into the installation shell. At this time, all the filtered impurities will be collected at the filter box, and part of the wastewater carried by the impurities will be filtered by the filter box and discharged back to the pretreatment box through the lower hole at the lower end of the installation shell;

[0017] When the filter screen box is tilted, it is only necessary to pull the block upward so that the block drives the limit block to slide on the frame of the installation shell. When the first block at the lower end of the limit block is separated from the first slot, the filter screen box can be pulled out of the installation shell and tilted. When installing after tilting, the filter screen box is inserted into the installation shell. During the insertion, one side of the filter screen box presses the inclined surface of the first block, so that the limit block connected to the first block slides on the frame, and the guide rod connected to the upper end of the limit block also slides accordingly. At the same time, the first spring on the outer side of the guide rod is squeezed until the snap-in end position of the first block corresponds to the first slot. At this time, the first spring resets and pushes the limit block, so that the first block on the limit block is snapped into the first slot to complete the fixation.

[0018] S4. After the initial pretreatment, the wastewater reaches the bottom of the pretreatment box and flows into the connected separation box. During this period, the wastewater passes through the porous activated carbon filter on the pretreatment box for re-adsorption and filtration to remove the dye particles and residual fabric fibers in the wastewater;

[0019] S5. When replacing the porous activated carbon filter element, it is only necessary to pull the moving handle on the sealing plate at the same time. The moving handle slides closer to each other on the sliding rod at the groove by pulling the moving plate. When the second clamping block on the moving plate is separated from the second clamping slot at the fixed slot, the sealing plate can be removed, and then the porous activated carbon filter element can be taken out and replaced. After replacement, the sealing plate is inserted into the fixed slot again. When the inclined surfaces of the second clamping ends on both sides of the sealing plate are squeezed, the moving plate connected to the second clamping block slides and compresses the second spring. When the second clamping block corresponds to the position of the second clamping slot, the second spring returns to its original position and pushes the second clamping block connected to the moving plate to be clamped into the second clamping slot to be fixed;

[0020] S6. After the wastewater passes through the pretreatment tank and enters the separation tank, an appropriate amount of flocculant is added through the dosing pipe. At the same time, the stirring motor on the tank cover is started. The stirring motor uses the stirrer at the end of the output shaft to quickly fuse the wastewater and flocculant in the separation tank, thereby separating them. First, a liquid pump is used to extract the upper clear liquid in the separation tank through the liquid pump pipe connected to the input end. The liquid is then transported to the next acid-base adjustment link for treatment through the pipeline at the output end of the liquid pump. After the wastewater is separated, the turbid liquid with a large amount of impurities in the lower layer is discharged through the sewage pipe, dried, and then collected.

[0021] S7. When the separation box is to be maintained after use, it is only necessary to operate the crank on the mounting frame to rotate the first rotating rod, and the first rotating rod transmits the sprocket on the second rotating rod through the sprocket and chain. When the second rotating rod rotates at the assembly hole, the first bevel gear on the second rotating rod engages and transmits the second bevel gear. At the same time, the screw connected to the second bevel gear rotates at the side groove of the mounting frame. Due to the synchronous operation of the two screws, the same connecting frame connected to the outer thread of the screw slides on the sliding column, and the connecting frame drives the box cover to open, and the inside of the separation box can be cleaned.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] First, in the present invention, the recycled wastewater can filter out larger debris through the filter grid at the upper end of the pretreatment box, and then, under the action of the inclined water guide plate of the pretreatment box, the wastewater is discharged onto the inclined filter screen through the gap between the inclined water guide plate and the pretreatment box, and the wastewater is washed and filtered downward from the high part of the inclined filter screen to the low part, and the filtered impurities and wastewater are discharged into the installation shell along the low part of the inclined filter screen and through the upper hole through the rectangular hole on the pretreatment box. At this time, all the filtered impurities will be collected at the filter box, and part of the wastewater carried by the impurities will be filtered by the filter box and discharged back to the pretreatment box through the lower hole at the lower end of the installation shell, thereby pre-treating and filtering the impurities in the wastewater, and at the same time, it can also effectively reduce the subsequent replacement of the porous activated carbon filter element to a certain extent, thereby reducing the use cost;

[0024] When the filter screen box is disassembled, the pulling block is lifted up so that the pulling block drives the limiting block to slide on the square frame of the installation shell. When the first blocking block at the lower end of the limiting block is separated from the first blocking slot, the filter screen box can be pulled out of the installation shell and dumped, thereby facilitating the disassembly and maintenance of the filter screen box.

[0025] Thirdly, in the present invention, after the porous activated carbon filter element is inserted into the fixing groove on the pretreatment box, the sealing plate is then inserted into the fixing groove. When the inclined surfaces of the second clamping blocks on both sides of the sealing plate are squeezed, the moving plate connected to the second clamping block slides and compresses the second spring. When the second clamping block corresponds to the position of the second clamping groove, the second spring returns to its original position and pushes the second clamping block connected to the moving plate to be clamped into the second clamping groove to fix it. After fixation, the lower end of the sealing plate is abutted against the porous activated carbon filter element, and the insertion frame is inserted into the sealing groove and squeezes the sealing strip in the sealing groove, thereby ensuring the sealing of the porous activated carbon filter element, thereby facilitating the replacement operation of the porous activated carbon filter element.

[0026] Fourthly, in the present invention, by operating the crank on the mounting frame, the crank shakes the first rotating rod to rotate, and the first rotating rod transmits the sprocket on the second rotating rod through the sprocket and the chain. When the second rotating rod rotates at the assembly hole, the first bevel gear on the second rotating rod engages and transmits the second bevel gear. At the same time, the screw connected to the second bevel gear can rotate at the side groove of the mounting frame. Due to the synchronous operation of the two screws, the same connecting frame connected to the outer thread of the screw slides on the sliding column, and the connecting frame drives the box cover to open, thereby facilitating the cleaning of the inside of the separation box.

At the same time, part of the filtered impurities and wastewater flow along the lower part of the oblique filter 401 and through the rectangular hole 403 on the pretreatment box 3 through the upper hole 503 and into the installation shell 501. At this time, all the filtered impurities will be collected at the filter box 502, and part of the wastewater carried by the impurities will be filtered by the filter box 502 and discharged back to the pretreatment box 3 through the lower hole 504 at the lower end of the installation shell 501.

[0048] S3, when the filter box 502 is tilted, it is only necessary to pull the block 904 upward so that the block 904 drives the limit block 902 to slide at the frame 901 of the installation shell 501. When the first clamping block 903 at the lower end of the limit block 902 is separated from the first clamping groove 505, the filter box 502 can be pulled out of the installation shell 501 and tilted. When installing after tilting, the filter box 502 is inserted into the installation shell 501. During the insertion, one side of the filter box 502 is against the first clamping block 90 3, so that the limiting block 902 connected to the first clamping block 903 slides at the frame 901, and the guide rod 905 connected to the upper end of the limiting block 902 also slides accordingly, and the first spring 906 on the outer side of the guide rod 905 is squeezed until the position of the clamping end of the first clamping block 903 corresponds to the first clamping groove 505. At this time, the first spring 906 resets and pushes the limiting block 902, so that the first clamping block 903 on the limiting block 902 is clamped into the first clamping groove 505 to complete the fixation;

[0049] S4, after the wastewater has undergone preliminary pretreatment, it reaches the bottom of the pretreatment box 3 and flows to the connected separation box 7. During this period, the wastewater passes through the porous activated carbon filter 302 on the pretreatment box 3 for further adsorption and filtration to remove dye particles and residual fabric fibers in the wastewater;

[0050] When the second clamping block 125 on the moving plate 124 is separated from the second clamping groove 304 at the fixing groove 301, the sealing plate 6 can be removed and replaced. After replacement, the sealing plate 6 can be inserted into the fixing groove 301 again. When the inclined surfaces of the second clamping blocks 125 on both sides of the sealing plate 6 are squeezed, the moving plate 124 connected to the second clamping block 125 slides and compresses the second spring 122. When the second clamping block 125 corresponds to the position of the second clamping groove 304, the second spring 122 is reset and pushes the second clamping block 125 connected to the moving plate 124 to be clamped into the second clamping groove 304 to be fixed.

[0051] S6. After the wastewater passes through the pretreatment box 3 and enters the separation box 7, an appropriate amount of flocculating agent is added through the dosing pipe 702. At the same time, the stirring motor 704 on the box cover 703 is started. The stirring motor 704 uses the stirrer at the end of the output shaft to quickly fuse the wastewater and flocculating agent in the separation box 7, thereby forming a separation. First, the upper clear liquid in the separation box 7 is extracted by the liquid extraction pump 705 through the liquid extraction pipe 706 connected to the input end. The liquid is then transported to the next acid-base adjustment link for treatment through the pipeline at the output end of the liquid extraction pump 705. After the wastewater is separated, the turbid liquid with a large amount of impurities in the lower layer is discharged through the sewage pipe 701, dried, and then collected.

[0052] S7. When the separation box 7 is maintained after use, it is only necessary to operate the crank 144 on the mounting frame 8. The crank 144 shakes the first rotating rod 145 to rotate, and the first rotating rod 145 transmits the sprocket 147 on the second rotating rod 148 through the sprocket 147 and the chain 146. When the second rotating rod 148 rotates at the assembly hole 1411, the first bevel gear 149 on the second rotating rod 148 engages and transmits the second bevel gear 1410. At the same time, the screw 143 connected to the second bevel gear 1410 rotates at the side groove 142 of the mounting frame 8. Due to the synchronous operation of the two screws 143, the same connecting frame 141 threadedly connected to the outer side of the screw 143 slides on the sliding column 15, and the connecting frame 141 drives the box cover 703 to open, and the inside of the separation box 7 can be cleaned.
