Description

Technical Field

[0001] This utility model relates to the field of textile dyeing wastewater treatment technology, and in particular to a wastewater recycling and treatment device for textile dyeing. Background Technology

[0002] The dyeing and printing wastewater treatment device is a specialized unit designed to treat high-concentration, recalcitrant wastewater generated by the dyeing and printing industry. It employs a combined process of "physicochemical pretreatment + hydrolysis acidification + biological contact oxidation + deep treatment," removing most suspended solids and some organic matter through units such as screens, equalization tanks, and coagulation sedimentation to improve the wastewater's biodegradability and further degrade organic matter. Activated carbon adsorption and membrane filtration technologies ensure that the effluent meets standards.

[0003] Chinese invention patent application CN211972712U discloses a dye recycling device for textile dyeing machines. This patent includes a housing, a lower cover plate, a placement plate, and a chute. A clamping roller and a guide roller are connected to the upper shaft of the housing. A heater is bolted to the housing. A fixed disk is connected to the upper shaft of a drive motor, and a fixed rod is welded to the fixed disk. A connecting rod is connected to the upper shaft of the fixed rod and is mounted on the upper cover plate. A lower cover plate is connected to the upper cover plate, and a brush block is screwed onto the lower cover plate. This dye recycling device for textile dyeing machines, equipped with a brush block, allows the fixed disk to drive the fixed rod to rotate within the chute. Under the action of the fixed rod, the connecting rod drives the upper and lower cover plates to reciprocate left and right on the fixed plate. The brush block effectively coats the dye on the textiles evenly, improving the device's efficiency.

[0004] In existing dyeing and printing wastewater treatment devices, filter cartridges are mainly used to purify and clean the wastewater. However, this static filtration method is not only inefficient but also highly dependent on the cleanliness of the filter cartridges, requiring frequent replacements, thus presenting certain drawbacks.

[0027] The rotary electrolysis assembly 2 includes a terminal post 5, which connects the electrolysis device of this device to an external power source; a rotating shaft 12 is mounted on one side of the terminal post 5, and the rotating shaft 12 achieves the rotation effect of the electrolysis device under the drive of the motor 15, thereby increasing the efficiency of electrolysis.

[0028] A bracket 6 is connected to one side of the power receiving post 5. A first conductive post 7 is provided on one side of the bracket 6. The first conductive post 7 and the second conductive post 8 provide the electrical energy required for electrolysis to the electrolysis plate 9 in the middle. A second conductive post 8 is provided on the other side of the first conductive post 7. The electrolysis plate 9 is fixedly installed between the first conductive post 7 and the second conductive post 8. The electrolysis plate 9 directly uses electrolysis to flocculate pollutants in the wastewater and achieves an interception effect at the sieve holes 10. The surface of the electrolysis plate 9 is arrayed with sieve holes 10.

[0029] The aforementioned waste liquid recycling and treatment device for textile printing and dyeing features a Z-shaped structure for the first conductive post 7 and the second conductive post 8. This structure increases the installation area of ​​the electrolysis plate 9, thereby improving the electrolysis effect of the device. The first conductive post 7, the second conductive post 8, and the connecting post 5 are interconnected.

[0030] The waste liquid recycling and treatment device for textile printing and dyeing is provided with filter cotton 11 at the bottom of the first conductive column 7 and the second conductive column 8. The filter cotton 11 is an auxiliary cleaning structure using traditional filtration methods.

[0031] The aforementioned waste liquid recycling and treatment device for textile printing and dyeing has a hollow internal structure for the support 6, which is mainly used for laying the wiring connecting the electrical terminal 5 and the conductive terminal. The wiring is laid inside the support 6.

[0032] The aforementioned wastewater recycling and treatment device for textile printing and dyeing also includes:

[0033] The rotating assembly includes a bearing hole 13 on one side of the processing tank 1, and a bearing 14 is disposed inside the bearing hole 13. The bearing 14 is a component for rotatably mounting a rotating shaft 12. The rotating shaft 12 is rotatably mounted inside the bearing 14, and a motor 15 is connected to one side of the rotating shaft 12. The motor 15 controls the rotation of this electrolysis device through the rotating shaft 12.

[0034] The aforementioned wastewater recycling and treatment device for textile printing and dyeing also includes:

[0035] The static filtration assembly 3 includes a filter element 16 installed at the bottom of the treatment tank 1. The filter element 16 is a component that cleans wastewater by physical filtration.

[0036] The aforementioned waste liquid recycling and treatment device for textile printing and dyeing includes foot pads 18 arranged in an array at the bottom of the treatment tank 1. The foot pads 18 are designed to enhance the support of the device. The foot pads 18 are made of an elastic, corrosion-resistant material.

[0037] Working principle:

[0038] In the actual design process, this utility model addresses the following shortcomings in existing technologies: "In existing dyeing and printing wastewater treatment devices, filter cartridges are mainly used to achieve the purification and cleaning effect of wastewater. However, this static filtration method is not only inefficient but also highly dependent on the cleanliness of the filter cartridges, requiring constant replacement, thus presenting certain drawbacks." Therefore, a rotary electrolysis component 2 and a static filtration component 3 are specifically proposed.

[0039] Rotary electrolysis unit 2:

[0040] This component overcomes the problems of low efficiency and frequent filter replacement required in existing technologies that directly precipitate waste liquid. By connecting the bottom of the electrode post 5 to the rotating shaft 12, and controlling the rotation of the electrode post 5 on the rotating shaft 12 via the motor 15, the entire electrolysis device rotates inside the tank. Because the electrolysis device is constantly in motion, the contact efficiency between the electrolysis plate 9 and the waste liquid is significantly improved. Furthermore, the electrolysis plate 9, electrically connected between the first conductive post 7 and the second conductive post 8 via the bracket 6, is connected via electrolysis, causing acidic substances in the waste liquid to form flocculent substances on the surface of the electrolysis plate 9, which are then intercepted on the surface of the sieve holes 10 during the rotation of the electrolysis plate 9. Due to the high efficiency of electrolysis, the wastewater treatment efficiency is also improved. In addition, the electrolysis plate 9 can be directly rinsed during cleaning, eliminating the difficulty of replacing filter cartridges.

[0041] Static filter component 3:

[0042] This component uses a traditional filtration method, primarily to supplement the electrolytic wastewater treatment process. The remaining wastewater is filtered on the surface of filter element 16, and wastewater that meets discharge standards is discharged through drain hole 17.

[0043] This invention utilizes a rotary electrolysis component. This component employs electrolytic flocculation to cause impurities in the waste liquid to agglomerate on the surface of the sieve openings. Because electrolysis is used, the cleaning efficiency is significantly improved. Furthermore, since the flocculants are directly adsorbed onto the sieve opening surface, subsequent cleaning is very simple; a simple rinse is sufficient. This avoids the difficulty of replacing filter cartridges in existing technologies, thus demonstrating its advanced nature. In addition, the motor-controlled rotation of the electrolysis device increases the efficiency of contact between the device and the waste liquid, and the Z-shaped conductive pillars increase the installation area of ​​the electrolysis plate, further enhancing the treatment effect of this device.
