Description

Technical Field

[0001] The invention relates to the technical field of dye recovery, and more specifically to a waste dye separation and recovery device for textiles. Background Art

[0002] Waste textile dyes usually contain harmful substances such as heavy metals, which are potentially harmful to health and the environment. If not handled properly, they will have a serious impact on the environment. The harmful substances in these dyes may penetrate into the soil and cause soil pollution. Under the erosion of rainwater, these harmful substances may also enter rivers, lakes and other water bodies, causing water quality deterioration and endangering the survival and reproduction of aquatic organisms.

[0003] At the same time, the recycling of waste dyes for textiles is of great significance. Through recycling, it can reduce pollution to the environment, save precious natural resources, and bring economic benefits to enterprises. Recycling methods include solvent extraction, biological fermentation, membrane separation and chemical extraction. These methods can convert waste dyes into new resources for the production of other products, such as recycled dyes, building materials, etc.

[0004] At present, in the recovery operation of waste dyes for textiles, when the unusable materials in the waste dyes are precipitated and filtered, the precipitates need to be treated regularly to prevent the precipitates from affecting the efficiency of the precipitation reaction or clogging the filter. In addition, during the precipitate treatment process, it is often necessary to temporarily stop the precipitation process of the waste dyes, thereby reducing the treatment efficiency of the waste dyes.

[0005] Therefore, in view of this, the existing structure is studied and improved, and a waste dye separation and recovery device for textile use is provided, in order to achieve a more practical purpose. Summary of the invention

A stepper motor 302 is fixedly installed on the outer side of the dye separation box 102. The output end of the stepper motor 302 is connected to the rotating shaft of the circulating pendulum 301 through a coupling.

The large bracket 307 is used to provide support for the solid material concentration tank 306. The scraped solid material passes through the discharge channel 305 and finally reaches the position of the solid material concentration tank 306, which is convenient for the centralized collection and processing of the solid material.

[0057] Embodiment 2:

[0058] Based on the above embodiment 1, further description is given.

[0059] See also Figure 1 , Figure 2 , Figure 3 Specifically, the basic platform 1 is a stepped structure, and the bottom height of the distillation tower 103 is lower than the bottom height of the dye recovery tank 101 .

[0060] The bottom height of the distillation tower 103 is ensured to ensure that the dye in the dye recovery tank 101 can smoothly reach the inside of the distillation tower 103 .

[0061] Specifically, a square opening 1011 is provided at the bottom of the dye recovery tank 101 and the solid material concentration tank 306 , and a sealing plate 1012 is fixedly installed at the square opening 1011 by bolts.

[0062] By removing the bolts, the sealing plate 1012 can be separated from the square opening 1011 , and the interior of the dye recovery tank 101 and the solid material concentration tank 306 can be easily cleaned through the large-diameter square opening 1011 .

[0063] See also Figure 5 , Figure 8 Specifically, an arc-shaped card plate 201 is clamped at the bottom end of the arc-shaped separation net 2, a hydraulic cylinder 202 is fixedly installed inside the dye recovery pool 101, the outside of the hydraulic cylinder 202 is wrapped with a waterproof shell, and a small bracket 203 is fixedly installed on the output shaft of the hydraulic cylinder 202, and the top of the small bracket 203 is fixed to the bottom end of the arc-shaped card plate 201.

[0064] By controlling the hydraulic cylinder 202, the height of the arc-shaped clamping plate 201 can be controlled. When the additive is put into the dye separation box 102, the arc-shaped clamping plate 201 can be used to block the arc-shaped separation net 2, thereby facilitating the waste dye on the arc-shaped separation net 2 to react with the additive to form precipitation.

[0065] See also Figure 4 , Figure 5 , Figure 6 Specifically, the circulating pendulum 301 is composed of a central rotating shaft 3011, a connecting plate 3012 and an arc-shaped hammer head 3013, and the connecting plate 3012 and the arc-shaped hammer head 3013 both rotate around the rotating axis of the central rotating shaft 3011.

[0066] The output end of the stepper motor 302 is connected to the rotating shaft of the central rotating shaft 3011 through a coupling.

[0067] The stepper motor 302 controls the rotation of the central shaft 3011 , thereby controlling the synchronous swing of the connecting plate 3012 and the arc-shaped hammer head 3013 , so as to scrape off the solid material on the arc-shaped separation net 2 .

[0068] Specifically, the arc radius value of the arc-shaped hammer head 3013 is equal to the arc radius value of the inner arc surface of the arc-shaped separation net 2.

[0069] It ensures that the arc-shaped hammer head 3013 and the arc-shaped separation net 2 have a good fit, thereby avoiding scraping dead corners on the arc-shaped separation net 2.

[0070] Both sides of the arc-shaped hammer head 3013 are provided with scraper structures.

[0071] The scraper mechanism can further improve the scraping effect of the arc-shaped hammer head 3013 on the solid material on the surface of the arc-shaped separation net 2.

[0072] Specifically, the maximum rotation angle of the connecting plate 3012 is 180°, and a plurality of water-permeable holes 3014 are provided on the connecting plate 3012. The water-permeable holes 3014 are uniformly arranged in a rectangular shape as a whole.

[0073] When the connecting plate 3012 rotates, the arc-shaped hammer head 3013 scrapes off the solid material on the arc-shaped separation net 2, and at the same time scrapes off a portion of the liquid dye. When the connecting plate 3012 rotates 180°, the liquid dye will flow back into the dye separation box 102 from the water permeable hole 3014.

[0074] See also Figure 4 , Figure 5 Specifically, a partition wall 1021 is fixedly installed on the inner top of the dye separation box 102 , and two scrapers 303 are respectively located on both sides of the partition wall 1021 .

[0075] When the circulating pendulum 301 is at the 0° position, one of the scrapers 303 can scrape solids from one side of the circulating pendulum 301. When the circulating pendulum 301 rotates 180°, the other scraper 303 can scrape solids from the other side of the circulating pendulum 301. Under the circulating operation of the two scrapers 303, the circulating pendulum 301 can continuously scrape the solids on the arc-shaped separation net 2, and finally move the solids to the solid concentration tank 306 for collection through the scrapers 303.

[0076] The control structure 304 is composed of a screw module 3041, a slide rod 3042, and a servo motor 3043. The screw module 3041 and the slide rod 3042 are both movably connected to the interior of the dye separation box 102 through waterproof bearings. The screw module 3041 is threadedly connected to one end of the scraper 303, and the slide rod 3042 is slidingly connected to the other end of the scraper 303. The servo motor 3043 is fixedly installed on the outer side of the dye separation box 102, and the output end of the servo motor 3043 is transmission-connected to the screw module 3041 through a coupling.

[0077] The servo motor 3043 controls the rotation of the screw module 3041, and the sliding limit of the scraper 303 by the sliding rod 3042 can realize precise control of the moving direction and moving distance of the scraper 303. When the scraper 303 moves from one end of the circulating pendulum 301 to the end of the circulating pendulum 301 close to the discharge channel 305, the solid material scraping of one end surface of the circulating pendulum 301 can be completed.

[0078] See also Figure 2 , Figure 7Specifically, the ventilation tube 6 with a valve is integrated by a main air tube 601, an air cavity 602, and a plurality of bronchi 603. The main air tube 601 and the air cavity 602 are both located outside the dye separation box 102, and the bronchi 603 are connected to the inside of the dye separation box 102.

[0079] The gas passes through the main air pipe 601 and the air cavity 602, and is finally ejected from different bronchi 603, increasing the contact area between the gas and the fuel. The ejected gas will mix into the dye and gradually rise. In this process, the dye will be stirred, accelerating the reaction between the dye and the additive to form a solid.

[0080] See also Figure 4 , Figure 5 Specifically, two liquid level sensors 1022 are embedded in the inner wall of the dye separation box 102, and the heights of the two liquid level sensors 1022 are higher than the height of the waste dye introduction pipe 4 with a valve.

[0081] The liquid level sensor 1022 can monitor the dye liquid level in the dye separation box 102, control the height of the liquid level sensor 1022, and avoid interference of the liquid sprayed from the waste dye introduction pipe 4 with valve and the additive introduction pipe 5 with valve on the liquid level monitoring.

[0082] When the circulating pendulum 301 is at 0° or 180°, the height of the liquid level sensor 1022 is lower than the height of the connecting plate 3012. When the liquid level sensor 1022 is completely submerged below the dye liquid level, the injection of waste dye and additives is stopped. In this way, the dye liquid can be prevented from accumulating on the end face of the connecting plate 3012 of the circulating pendulum 301.

[0083] Working principle:

[0084] The entire device consists of four parts: textile waste fuel injection, precipitation reaction, solid-liquid separation, solid material removal and post-processing.

[0085] First, the waste dye introduction pipe 4 with a valve is connected to a pump to introduce waste into the dye separation box 102.

[0086] Then, different additives are introduced into three additive introduction pipes 5 with valves respectively to achieve the aggregation and precipitation of harmful substances, waste and material fragments in the waste dyes, which is convenient for the centralized cleaning of solid materials. The ventilation pipe 6 with a valve is connected to the air pump to continuously introduce air into the dye separation box 102 to accelerate the aggregation and precipitation reaction process.

[0087] Then, the sedimentation cleaning component 3 cooperates with the arc separation net 2 to carry out solid-liquid separation and solid material removal process, specifically: the hydraulic cylinder 202 controls the height of the arc clamping plate 201 to drop, so that the liquid falls from the arc separation net 2 into the dye recovery pool 101, and then, the dye is quantitatively extracted from the dye recovery pool 101 into the distillation tower 103 for distillation and purification. After purification, the dye is discharged from the discharge pipe, and the operation of separation, recovery and reuse of the waste dye is completed.

[0088] During the filtering and separation process, the solid material is retained on the arc separation net 2. At this time, the stepper motor 302 is started, and the circulating pendulum 301 can be controlled to rotate 180°. During this process, the circulating pendulum 301 scrapes the solid material accumulated on the arc separation net 2 and accumulates on the surface of the circulating pendulum 301. At this time, the liquid dye will flow back from the water permeable hole 3014 to the dye separation box 102. Then, the servo motor 3043 controls the screw module 3041 to rotate, and the sliding limit of the scraper 303 by the sliding rod 3042 can realize the precise control of the moving direction and moving distance of the scraper 303. When the scraper 303 moves from one end of the circulating pendulum 301 to the end of the circulating pendulum 301 close to the discharge channel 305, the solid material passes through the discharge channel 305 to reach the solid material concentration tank 306, and the solid material scraping of one end face of the circulating pendulum 301 can be completed.

[0089] Finally, in later processing, the sealing plate 1012 can be separated from the square opening 1011 by removing the bolts, and the interior of the dye recovery tank 101 and the solid material concentration tank 306 can be easily cleaned through the large-diameter square opening 1011.

[0090] In this way, the use of the entire device can be completed.

[0091] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
