Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a multi-stage sedimentation device for yarn dyeing wastewater. Background Technology

[0002] In the current era of rapid development in the textile industry, yarn dyeing, as a key production link, not only gives yarn rich colors but also generates a large amount of dyeing wastewater containing dyes, auxiliaries, and fiber impurities. If this wastewater is discharged directly without effective treatment, it will not only cause water pollution and damage the ecological environment but also harm human health through the food chain. Therefore, multi-stage sedimentation devices for yarn dyeing wastewater have emerged. Through multi-stage sedimentation and filtration processes, these devices gradually remove various pollutants from the wastewater, enabling the water quality to meet discharge standards or achieve recycling. This is of great significance for promoting the green and sustainable development of the textile industry.

[0003] Traditional multi-stage sedimentation devices for yarn dyeing wastewater typically rely on the coordinated operation of different sedimentation tanks and filter components to classify and treat wastewater. The filter components, as key components ensuring effluent quality, are prone to clogging by impurities in the wastewater after prolonged use, leading to decreased filtration efficiency and even wastewater leakage. To address this problem, existing devices install scrapers at the edges of the filter components, using left and right scraping motions to clear impurities from the surface and maintain filtration efficiency. However, this method only provides simple displacement of impurities on the filter component surface and fails to completely remove them. Impurities remain inside the filter components despite being pushed by the scrapers. As operating time increases, impurities accumulate, increasing filtration resistance and further reducing filtration efficiency. Furthermore, when impurities accumulate to a certain level, internal pressure imbalance can occur, potentially breaching weak points in the filter components and causing leakage. Therefore, a multi-stage sedimentation device for yarn dyeing wastewater is proposed to solve these problems. Utility Model Content

[0032] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a multi-stage sedimentation device for yarn dyeing wastewater, comprising a base 1, a support frame 2, and a water tank 3. A mixing tank 4 is fixedly connected to the inner side of the support frame 2, providing a stable support platform for the mixing tank 4.

A collection mechanism 10 is provided at the top; the slag discharge mechanism 5 includes a filter box 501, which is fixedly connected to the inner side of the water tank 3. The filter box 501 and the water tank 3 are integrally formed. The front side of the filter box 501 is connected to the water tank 3, so that impurities can be discharged through the outlet on the front side. Two sliding grooves 502 are opened on the front side of the water tank 3. Iron columns 503 are fixedly connected to the inner side of each of the two sliding grooves 502. The iron columns 503 are installed in the sliding grooves 502. Electromagnetic suction columns 504 are slidably connected to the inner side of the two sliding grooves 502. A sealing plate 505 is fixedly connected to the front end of each of the two electromagnetic suction columns 504. An electric box 506 is fixedly connected to the front side of the sealing plate 505. The sealing plate 505 is installed and slidably connected to the electromagnetic suction column 504. In the chute 502, after the starting box 506 energizes the electromagnetic suction column 504, a magnetic force is generated, and it quickly attracts the iron column 503 in the chute 502, completing the sealing treatment of the outlet by the sealing plate 505. The top column 507 is fixedly connected to the rear side of the sealing plate 505. A cleaning component 508 is provided inside the filter box 501. The cleaning component 508 includes a cylinder 5081, which is fixedly connected to the rear side of the water tank 3. One end of the cylinder 5081 passes through the rear side of the water tank 3 and is fixedly connected to a scraper 5082. By periodically activating the cylinder 5081, the scraper 5082 inside the filter box 501 is driven to slide, thereby scraping away internal impurities. It continues to slide forward, cleaning the top column. 507 is pushed forward, causing the sealing plate 505 to unfold and allowing impurities to be discharged smoothly. After scraping, the sealing plate 505 quickly resets under the action of magnetic attraction. The collection mechanism 10 includes a slag discharge plate 1001, which is fixedly connected to the front side of the water tank 3. A collection box 1002 is provided on the top front side of the base 1. The scraped impurities flow precisely into the collection box 1002 along the slag discharge plate 1001. The drainage mechanism 9 includes a liquid level sensor 901, which is fixedly connected to the right side of the water tank 3. A water pump 902 is connected to the bottom of the water tank 3.

[0033] Specifically, the support frame 2 provides a stable support platform for the mixing tank 4, ensuring the stability of the mixing tank 4 during operation. The slag discharge mechanism 5 is used to quickly discharge the filtered impurities to keep the inside of the water tank 3 clean, thereby improving filtration efficiency. A mixing mechanism 6 is provided inside the mixing tank 4. The main function of the mixing mechanism 6 is to quickly mix the sewage and flocculant to promote flocculation and accelerate the sedimentation of impurities. The bottom of the mixing tank 4 is connected to a drain pipe 7.

To ensure the stability and durability of the drain pipe 7, a reinforcement mechanism 8 is provided on its outer wall. A drain mechanism 9 is provided on the right side of the water tank 3 to drain the water in the water tank 3 to maintain the water level of the water tank 3. A collection mechanism 10 is provided on the top of the base 1 to collect the treated sewage and ensure that the sewage is properly treated. The front of the filter box 501 is connected to the water tank 3, allowing impurities to be discharged through the front outlet. The iron column 503 is installed in the slide 502, which is the rear... The sealing plate 505 provides a moving track. After the starting box 506 energizes the electromagnetic suction column 504, it generates magnetic force and quickly attracts the iron column 503 in the slide groove 502, completing the sealing treatment of the outlet by the sealing plate 505. By periodically starting the cylinder 5081, the scraper 5082 inside the filter box 501 is driven to slide, scraping away the internal impurities. It continues to slide forward, pushing the top column 507 forward, causing the sealing plate 505 to unfold and smoothly discharge the impurities. After scraping is completed, the sealing plate... Under the magnetic attraction, filter 505 quickly resets, ensuring the resealing of filter box 501 and preventing sewage leakage. The scraped impurities flow precisely into collection box 1002 along the slag discharge plate 1001, thus achieving effective collection and treatment of impurities. Liquid level sensor 901 is installed on water tank 3 to monitor the water level after filtration inside water tank 3 in real time. When the filtered water inside water tank 3 reaches a certain height, water pump 902 is controlled to discharge water to maintain the water level in water tank 3 and ensure the continuity and stability of the filtration process.

[0034] Reference Figure 1 , Figure 4 and Figure 5The mixing mechanism 6 includes a water inlet pipe 601, which is connected to the left side of the outer wall of the mixing tank 4. The water inlet pipe 601 is connected to the edge of the outer wall of the mixing tank 4, so that the water flowing into the mixing tank 4 can generate a vortex. The top of the mixing tank 4 is connected to nozzles 602 around its perimeter. The top of each nozzle 602 is connected to a connecting pipe 603. Each adjacent connecting pipe 603 is connected to an injection pipe 604. The flocculant enters the injection pipe 604 and is injected in batches into the nozzles 602 through the connecting pipes 603. Finally, the flocculant is evenly sprayed onto the mixing tank 4 through the nozzles 602. In this system, a spiral plate 605 is fixedly connected to the top inner side of the mixing tank 4. The vortex generated is guided by the spiral plate 605 to ensure the flow direction. An agitator 606 is provided inside the mixing tank 4. The agitator 606 includes a servo motor 6061, which is fixedly connected to the top of the mixing tank 4. The output end of the servo motor 6061 passes through the top of the mixing tank 4 and is fixedly connected to a rotating rod 6062. Multiple agitator rods 6063 are fixedly connected to the outer wall of the rotating rod 6062. The agitator rods 6063 are driven by the servo motor 6061 to agitate the wastewater and flocculant.

[0035] Specifically, firstly, the connection point of the inlet pipe 601 is located at the outer edge of the mixing tank 4, ensuring that water can be directly injected into the interior of the mixing tank 4 through the inlet pipe 601. This helps to generate a strong vortex effect in the tank, which is crucial for the mixing process. It promotes full contact and mixing between the wastewater and the flocculant. To further enhance the mixing effect, multiple nozzles 602 are evenly arranged around the top of the mixing tank 4. The flocculant is injected into the nozzles 602 in batches through the injection pipe 604. When the flocculant is sprayed through the nozzles 602, it can be evenly distributed throughout the entire space of the mixing tank 4, ensuring full mixing between the flocculant and the wastewater. Under the guidance of the spiral plate 605, the wastewater and flocculant undergo preliminary mixing treatment, improving the uniformity of mixing. In addition, when the servo motor 6061 is started, the rotating rod 6062 drives the stirring rod 6063 to rotate, thereby fully stirring the wastewater and flocculant to ensure a thorough and efficient mixing process.

[0036] Reference Figure 3 , Figure 4 and Figure 5 The reinforcement mechanism 8 includes a reinforcement ring 801, which is fixedly connected to the outer wall of the drain pipe 7. Support rods 802 are fixedly connected to the front and rear sides of the outer wall of the reinforcement ring 801. The reinforcement ring 801 and the support rods 802 are integrally formed. The reinforcement mechanism 8, together with the support frame 2, supports the drain pipe 7. The electrical box 506 is electrically connected to the electromagnetic suction column 504. The bottom of the support frame 2 is fixedly connected to the top of the base 1.

[0037] Specifically, the support rod 802 and the reinforcing ring 801 are integrally formed, ensuring the stability of the structure. With the cooperation of the reinforcing mechanism 8, the drain pipe 7 can be effectively supported to enhance its structural stability and durability. In addition, the electrical box 506 and the electromagnetic suction column 504 are electrically connected, and the support frame 2 is fixed on the top of the base 1, which not only improves the overall structural stability but also facilitates installation and maintenance.

[0038] Working principle: First, the wastewater and flocculant are quickly mixed and then discharged into the filter box 501 through the drain pipe 7. The filter box 501 filters the internal impurities. By periodically starting the cylinder 5081, the scraper 5082 inside the filter box 501 is driven to slide, scraping away the internal impurities. It continues to slide forward, pushing the top column 507 forward, causing the sealing plate 505 to unfold and smoothly discharge the impurities. The scraped impurities flow into the collection box 1002 along the slag discharge plate 1001. After scraping is completed, the electric box 506 is started to energize the electromagnetic suction column 504, generating magnetic force, which quickly attracts the iron column 503 in the chute 502, completing the sealing treatment of the outlet by the sealing plate 505. This enables the periodic cleaning of impurities.

[0039] Furthermore, wastewater is injected into the mixing tank 4 through the inlet pipe 601. The connection angle of the inlet pipe 601 causes the water flow into the mixing tank 4 to generate a vortex, and under the guidance of the spiral plate 605, the flow rate and stability are ensured. At this time, the flocculant enters the injection pipe 604 and is injected into the nozzle 602 in batches through the connecting pipe 603. Finally, the flocculant is evenly sprayed into the mixing tank 4 through the nozzle 602. The generated vortex causes the wastewater and flocculant to undergo preliminary mixing treatment. Then, the servo motor 6061 is started to drive the stirring rod 6063 on the rotating rod 6062 to fully stir the wastewater and flocculant, thereby improving the decomposition efficiency.
