Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment for fabric processing, and in particular to a wastewater treatment device for fabric printing and dyeing. Background Technology

[0002] Dyeing and printing wastewater refers to the wastewater discharged from dyeing and printing factories that process cotton, linen, chemical fibers and their blended products, silk, wool dyeing and finishing factories, and silk factories. The volume and quality of dyeing and printing wastewater vary depending on the type of fiber and the processing technology. Among them, dyeing and printing factories produce large volumes of wastewater, which is characterized by large volume, high content of organic pollutants, high alkalinity, and large fluctuations in water quality. It is one of the most difficult industrial wastewaters to treat. The wastewater contains dyes, sizing agents, auxiliaries, oils, acids and alkalis, fiber impurities, sand, inorganic salts, etc.

[0003] After wastewater is treated by screens, bar screens and other equipment to remove suspended and floating solids, coagulants (such as basic aluminum chloride, polyacrylamide, etc.) need to be added to coagulate the small particles into larger particles, which facilitates sedimentation. Traditional wastewater treatment devices directly add coagulants to the wastewater and then mix the wastewater and coagulants with a stirring device. If coagulants are mixed while wastewater is being introduced, the sedimentation effect in the sedimentation tank will be affected, thus reducing the sedimentation efficiency. Utility Model Content

Detailed Implementation

[0026] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please refer to Figures 1 to 5 As shown, a fabric dyeing wastewater treatment device of the present invention includes a sedimentation tank 3 and a mixing mechanism 4, wherein the mixing mechanism 4 is provided on the upper part of the sedimentation tank 3;

[0028] The mixing mechanism 4 includes a mixing tank 401, a flushing assembly, a rotating assembly, a seepage pipe 405, and a stirring element 406. The mixing tank 401 is located above the sedimentation tank 3, and has a liquid inlet at its lower part, which is connected to the interior of the sedimentation tank 3. The seepage pipe 405 is located inside the mixing tank 401, and its upper part is rotatably connected to the upper part of the mixing tank 401. Several seepage ports 404 are arranged around the lower part of the seepage pipe 405, and several stirring elements 406 are fixedly connected to the outer surface of the seepage pipe 405. The stirring elements 406 and the seepage ports 404 are arranged alternately. The rotating assembly is driven to the seepage pipe 405, and has a feed inlet at its top. The flushing assembly is connected to the interior of the mixing tank 401.

[0029] The working principle of this utility model is as follows: In actual production and use, when it is necessary to treat fabric dyeing wastewater, the coagulant is first put into the seepage pipe 405, and then the wastewater is flushed through the flushing component to the seepage pipe 405, so that the coagulant particles inside the seepage pipe 405 are dissolved under the flushing of the wastewater, and discharged into the mixing tank 401 through the seepage port 404. At the same time, the rotating component is operated, so that the rotating component drives the stirring component 406 through the seepage pipe 405 to stir and mix the wastewater and coagulant again. Then the wastewater in the mixing tank 401 enters the sedimentation tank 3 through the feed port for sedimentation.

[0030] Furthermore, the flushing assembly includes a manifold 409, a pump 403, a diverter 407, and a flushing pipe 408. A plurality of diverter 407s are arranged around the outside of the mixing tank 401. A plurality of flushing pipes 408 are arranged from top to bottom on each diverter 407. The side wall of the mixing tank 401 has mounting holes adapted to the flushing pipes 408. One flushing pipe 408 passes through one of the mounting holes. One end of the flushing pipe 408 is connected to the diverter 407, and the other end is located inside the mixing tank 401. Each diverter 407 is connected to the lower part of the manifold 409. An inlet hole is provided on the upper part of the manifold 409, and the pump 403 is installed on the inlet hole.

[0031] As can be seen from the above description, when it is necessary to mix wastewater with coagulant, the pump 403 can be operated to pump the wastewater into the collection pipe 409. Then, the water inside the collection pipe 409 enters the flushing pipe 408 through the diversion pipe 407, and the flushing pipe 408 flushes the wastewater onto the seepage pipe 405, so that the wastewater comes into contact with the coagulant through the seepage port 404, causing the coagulant to dissolve and mix with the wastewater.

[0032] Furthermore, the rotating assembly includes a rotating drive 411, a first gear 402, and a second gear 410. The first gear 402 is sleeved on the outside of the seepage pipe 405, and the second gear 410 is rotatably connected to the upper part of the mixing tank 401. The second gear 410 meshes with the first gear 402, and the rotating drive 411 is rotatably driven by the second gear 410.

[0033] As can be seen from the above description, when better mixing of coagulant and wastewater is required, while flushing liquid from flushing pipe 408 to seepage pipe 405, the rotating drive component 411 is operated. The rotating drive component 411 drives the first gear 402 to rotate through the second gear 410, thereby causing the second gear 410 to drive the agitator 406 to rotate through seepage pipe 405. The agitator 406 agitates the wastewater still in mixing tank 401, thereby enabling better mixing of coagulant and wastewater.

[0034] Furthermore, it also includes a feeding pipe 5 and a fixing component 6. The feeding pipe 5 is fixedly connected to the outside of the mixing tank 401, and the lower part of the feeding pipe 5 is rotatably connected to the upper part of the seepage pipe 405.

[0035] As can be seen from the above description, it is beneficial to fix the feeding pipe 5 to the upper part of the mixing tank 401, so as to facilitate better feeding.

[0036] Furthermore, it also includes a first valve body. The sedimentation tank 3 has several drain outlets 1 arranged from top to bottom, and the first valve body is installed inside each drain outlet 1.

[0037] As can be seen from the above description, the sedimentation tank 3 is conducive to the sedimentation of flocculants in the wastewater, so as to separate the solid and liquid in the wastewater. When it is necessary to discharge the separated liquid in the sedimentation tank 3, the first valve body at the height of the liquid stratification position can be operated to open the drain outlet 1, and then the liquid is discharged from the drain outlet 1.

[0038] Furthermore, a cleaning port is provided at the top of the sedimentation tank 3, and a door panel 2 is hinged to the cleaning port.

[0039] As can be seen from the above description, it is beneficial to clean and discharge the sediment through the cleaning port.

[0040] Furthermore, a slag discharge port is provided at the bottom of the sedimentation tank 3, and a second valve body 7 is provided on the slag discharge port.

[0041] As can be seen from the above description, it is beneficial to discharge the sediment into the sedimentation tank 3 through the slag discharge port.

[0042] Furthermore, it also includes a PLC controller, which is electrically connected to the mixing mechanism 4.

[0043] As can be seen from the above description, it is beneficial to adjust the parameters of the fabric dyeing wastewater treatment device through the PLC controller, and it makes it more convenient for operators to operate the fabric dyeing wastewater treatment device. Example 1
