Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a device for collecting wastewater from denim processing. Background Technology

[0002] In the denim manufacturing industry, the washing process is crucial in giving denim products their unique style and texture. However, the washing process generates a large amount of wastewater, which contains not only high concentrations of organic matter and suspended solids, but also debris such as loose threads, fabric scraps, and fibers generated during denim processing. If this wastewater is discharged directly without effective treatment, it will cause serious environmental pollution. Therefore, it is essential to use a wastewater collection system to transport the wastewater from the washing equipment's drainpipe to a wastewater equalization tank for subsequent purification treatment.

[0003] Currently, existing wastewater collection devices for denim processing have many problems. First, during wastewater transport, due to the lack of effective waste interception measures, loose threads, scraps of fabric, and other debris easily enter the pipes with the water flow. Over time, this debris gradually accumulates inside the pipes, not only reducing the pipe's cross-sectional area and lowering wastewater transport efficiency, but also potentially causing blockages that affect the normal operation of the entire washing production line and increase equipment maintenance and cleaning costs. Moreover, when pipes are blocked, cleaning is often very difficult, requiring a significant amount of manpower and time, and may also cause damage to the pipes.

[0004] Secondly, most existing collection devices lack the capability for pre-treatment of wastewater. Wastewater is discharged directly from the washing equipment into the equalization tank, where a considerable amount of time is required to add wastewater treatment agents to adjust the pH and remove some pollutants. This not only prolongs the overall wastewater treatment cycle and reduces treatment efficiency but also increases the cost. Furthermore, due to the lack of pre-mixing treatment, the mixing effect between the wastewater treatment agent and the wastewater may be unsatisfactory, affecting the effectiveness of subsequent treatment processes.

[0005] Furthermore, when it is necessary to clean or replace the components in the collection device used to intercept waste, the lack of an effective wastewater blocking mechanism makes it difficult to operate without affecting the normal flow of wastewater. Stopping the entire washing equipment to replace components would severely impact production schedules and cause economic losses; however, if the equipment is not stopped, wastewater will continue to flow during the replacement process, causing significant inconvenience to cleaning and replacement work and potentially leading to wastewater leakage and environmental pollution.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 9This invention provides a technical solution: a device for collecting wastewater from denim processing washing, comprising a water pollution treatment and collection pipe 1, which is installed between the drain pipe of the denim processing washing equipment and the wastewater regulating tank. A pre-reserved groove 101 is provided at the top of the water pollution treatment and collection pipe 1, and a sealing cover 102 is inserted into the groove 101. A connecting ring 107 is fixed to the bottom of the sealing cover 102, and a protective frame 3 is bolted to the connecting ring 107. A metal mesh plate 301 is fixed to one end of the protective frame 3 at its inner ring opening. The sealing cover 102 has a semi-circular ring structure with a "T"-shaped end face, and rubber sealing gaskets 103 are fixed to both ends of the sealing cover 102. 103 is an arc plate with an "L"-shaped end face. Both ends of the hoop plate 104 are fixed with connecting blocks 105 on both sides. The connecting blocks 105 are fixed to the bracket 2 by anti-loosening screws 106. The bracket 2 has a "T"-shaped plate structure. The top surface of the bracket 2 is provided with an arc surface that matches the water pollution treatment collection pipe 1. Both sides of the bracket 2 are provided with side grooves 201. An electric telescopic rod 202 is fixed inside the side groove 201. The piston rod of the electric telescopic rod 202 is fixed to the bottom surface of the hoop plate 104. The enclosure frame 3 is a round tube with an "L"-shaped end face. Multiple screws are inserted into the surface of the connecting ring 107. One end of the screw is fixed to the surface of the enclosure frame 3. The other end of the screw is fitted with a washer and a nut.

[0020] The retaining frame 3, in conjunction with the metal mesh plate 301, will obstruct the transport of waste from the sewage in the water pollution treatment collection pipe 1. When it is necessary to clean the waste inside the retaining frame 3, ensure that the water pollution treatment collection pipe 1 is not supplying water, remove the anti-loosening screw 106, and then trigger the switch of the electric telescopic rod 202. The electric telescopic rod 202 supports the hoop plate 104 upwards, and the hoop plate 104 pulls the sealing cover 102 up until the retaining frame 3 is suspended above the water pollution treatment collection pipe 1. Then loosen the nut, and after one end of the retaining frame 3 and the connecting ring 107 are no longer restricted, [the following text is missing: "…"] The protective frame 3 is pulled out and removed from under the sealing cover 102. Another protective frame 3 is pushed under the sealing cover 102 and installed on the connecting ring 107 using screws and nuts. The side groove 201 is activated to pull the hoop 104 down until the protective frame 3 falls into the interior of the water pollution treatment collection pipe 1. Then, the connecting block 105 is fixed to the bracket 2 using the anti-loosening screw 106. At this time, the rubber sealing gasket 103 is clamped between the sealing cover 102 and the water pollution treatment collection pipe 1 to achieve a seal. Finally, the removed protective frame 3 is transferred to the garbage disposal point for treatment.

[0021] To prevent a large amount of debris from leaking out of the end openings from inside the dismantled enclosure 3, the following measures were proposed: An installation ring 302 is inserted into the other end of the enclosure frame 3. The installation ring 302 is fixed to the enclosure frame 3 by multiple anti-loosening screws 306. A limiting mesh frame 303 is fixed to the inner ring surface of the installation ring 302. The limiting mesh frame 303 has a frustum-shaped tubular structure. Multiple reinforcing rods 304 are fixed to the outer ring surface of the limiting mesh frame 303. Reinforcing rings 305 are fixed to the inner ring opening of the limiting mesh frame 303 and the outer side of the multiple reinforcing rods 304.

[0022] When it is necessary to empty the garbage inside the enclosure frame 3, the anti-loosening screw 306 can be loosened to remove the mounting ring 302 from the other end of the enclosure frame 3. Then, the mounting ring 302 can be pulled to remove the limiting mesh frame 303 from the other end of the enclosure frame 3. Finally, the enclosure frame 3 can be inverted to clean out the garbage inside.

[0023] In order to pre-treat sewage by placing a sewage treatment machine when sewage is transported in water pollution treatment collection pipe 1, the following is proposed: Two collection cylinders 4 are fixedly inserted into the top of the water pollution treatment collection pipe 1. Multiple through holes 402 are opened on the surface of each collection cylinder 4. A suspension frame 403 is installed inside each collection cylinder 4. A stirring shaft 405 is rotatably connected to the bottom of the suspension frame 403. A sealing cover 407 is installed between the suspension frame 403 and the collection cylinder 4. A material injection valve pipe 408 is fixedly inserted into the top of the sealing cover 407. The material injection valve pipe 408 is connected to a wastewater treatment agent delivery pipe, introducing the wastewater treatment agent into the collection cylinder 4. After being mixed by the stirring shaft 405, the agent is then incorporated into the wastewater through the through holes 402. The collection cylinder 4 has a cylindrical structure, and the bottom of the collection cylinder 4... A circular groove is provided on the surface, and a pad 401 is inserted into the circular groove. The pad 401 is fixed to the inner wall of the water pollution treatment collection pipe 1. Multiple connecting rods 406 are fixed between the suspension frame 403 and the collection cylinder 4. A servo motor 404 is fixed inside the suspension frame 403. The top end of the stirring shaft 405 passes through the bottom plate of the suspension frame 403 and is connected to the power output end of the servo motor 404. The sealing cover 407 is fixed to the top surface of the suspension frame 403 by multiple anti-loosening screws. A sealing ring is fitted and fixed on the outer wall of the sealing cover 407. The sealing ring is clamped between the sealing cover 407 and the collection cylinder 4.

[0024] A pipeline for conveying wastewater treatment agent is installed and connected to the end of the injection valve pipe 408. Wastewater treatment agent is added to the injection valve pipe 408 through the feeding device, and the valve of the injection valve pipe 408 is opened. The injection valve pipe 408 introduces the wastewater treatment agent into the receiving cylinder 4. At the same time, the servo motor 404 is triggered to switch on and off. The servo motor 404 drives the stirring shaft 405 to stir the wastewater and the wastewater treatment agent. The through hole 402 outputs the mixed liquid of wastewater and wastewater treatment agent. In this way, after the wastewater is transported to the equalization tank, the operation time for adding wastewater treatment agent is reduced.

[0025] In order to close one end of the water pollution treatment collection pipe 1, block the sewage transportation, and facilitate the replacement of the enclosure frame 3, the following is proposed: One end of the water pollution treatment collection pipe 1 is rotatably connected with a sluice gate 5 inside; a second sealing ring 501 is sleeved and fixed outside the sluice gate 5, and the second sealing ring 501 is clamped between the sluice gate 5 and the water pollution treatment collection pipe 1. A limiting shaft 502 is fixed at the bottom end of the sluice gate 5, and the limiting shaft 502 is inserted into a groove opened on the inner wall of the water pollution treatment collection pipe 1. A traction handle 503 is fixed at the top end of the sluice gate 5, and a sealing bearing 505 is sleeved and fixed on the traction handle 503. The outer ring of the sealing bearing 505 is fixed in an installation opening 108 opened on the surface of the water pollution treatment collection pipe 1; an installation frame 507 is fixed on the top surface of the water pollution treatment collection pipe 1. The installation frame 507 is in a "U"-shaped plate structure. A second servo motor 508 is fixed on the top surface of the installation frame 507. The rotating shaft of the second servo motor 508 penetrates through the top plate of the installation frame 507 and is fixed with a driving gear 509. A driven gear 504 is engaged on one side of the driving gear 509, and the driven gear 504 is fixed at the top end of the traction handle 503.

[0026] The torque of the second servo motor 508 satisfies that when the driving gear 509 drives the driven gear 504 to rotate, it drives the sluice gate 5 to rotate. After the sluice gate 5 blocks the notch of the water pollution treatment collection pipe 1, the sewage transportation is blocked, which is convenient for the replacement of the enclosure frame 3; a plurality of anti-loosening screws three 506 are screwed on the top end of the driven gear 504, and the bottom ends of the anti-loosening screws three 506 are screwed on the surface of the water pollution treatment collection pipe 1. The addition of the anti-loosening screws three 506 is to prevent the sluice gate 5 from rotating after being adjusted. It should be noted that when the driven gear 504 needs to rotate, the anti-loosening screws three 506 must be loosened first until they are separated from the water pollution treatment collection pipe 1.

[0027] Usage method of the denim processing wastewater collection device for water washing: Install the water pollution treatment collection pipe 1 between the drainage pipe of the denim processing water washing equipment and the sewage regulation tank, and ensure that the flange connections at both ends are tight. Insert the sealing cover 102 into the reserved groove 101, so that the "L"-shaped arc surface of the rubber sealing gasket 103 fits the pipe wall. Fix the connecting blocks 105 at both ends of the hoop plate 104 to the bracket 2 through the anti-loosening screws one 106. The arc surface of the bracket 2 needs to fit the pipe wall completely. Start the electric telescopic rod 202 to press down the hoop plate 104, so that the sealing cover 102 is pressed tightly against the pipe wall, and check that there is no leakage in the rubber sealing gasket 103. Insert the enclosure frame 3 into the connecting ring 107 below the sealing cover 102, and fasten it with screws, washers and nuts. Install the installation ring 302 at the other end of the enclosure frame 3, and fix it through the anti-loosening screws two 306, ensuring that the limiting wire mesh frame 303 completely covers the opening.

[0028] During wastewater transport and waste interception, the washing equipment is activated, and the wastewater enters the water pollution treatment collection pipe 1 through the drainage pipe. The metal mesh plate 301 of the enclosure frame 3 intercepts floating stones, fibers, and other waste in the wastewater, and the limiting mesh 303 prevents waste from leaking out from the end. The sewage treatment agent delivery pipe is connected to the injection valve pipe 408, and the valve is opened. After the agent enters the collection cylinder 4, the servo motor 404 is activated to drive the stirring shaft 405 to rotate, and the mixed agent is evenly mixed into the wastewater through the through hole 402. The sealing cover 407 and the collection cylinder 4 are sealed by the sealing ring to prevent agent leakage. The anti-loosening screw 506 is loosened, and the servo motor 508 is activated to drive the drive gear 509, which drives the gate 5 to rotate to a vertical position through the driven gear 504, sealing the pipe opening. After confirming that the gate 5 is completely closed, the anti-loosening screw 506 is tightened again to prevent the gate 5 from rotating accidentally. Turn off the power to the electric telescopic pole 202, loosen the anti-loosening screw 106, and start the electric telescopic pole 202 to lift the hoop plate 104, pulling the sealing cover 102 upward. When the enclosure frame 3 is suspended above the pipe opening, loosen the nut and remove the enclosure frame 3, keeping the sealing cover 102 connected to the connecting ring 107. Loosen the anti-loosening screw 306, and remove the mounting ring 302 and the limiting mesh frame 303. Invert the enclosure frame 3 and dump the internal waste into the designated collection point. Insert the new enclosure frame 3 into the connecting ring 107 and tighten it with screws, washers, and nuts. Reinstall the limiting mesh frame 303 and the mounting ring 302, and tighten the anti-loosening screw 306. Start the electric telescopic pole 202 to press down the hoop plate 104, causing the enclosure frame 3 to fall into the pipe, and retighten the anti-loosening screw 106. Loosen the anti-loosening screw 3 506, start the servo motor 2 508 to rotate the gate 5 in the reverse direction to the horizontal position, restoring wastewater flow. Tighten the anti-loosening screw 3 506, and check the gate 5 sealing ring 2 501 for leaks. If the stirring shaft 405 is stuck, turn off the power to the servo motor 1 404, remove the sealing cover 407, and check the suspension bracket 403 and connecting rod 406. When cleaning the blockage of the through hole 402, the wastewater supply must be stopped first and the collection cylinder 4 must be removed.
