Description

Technical Field

[0001] The utility model relates to the technical field of printing and dyeing wastewater treatment, in particular to a printing and dyeing wastewater treatment device. Background Art

[0002] Printing and dyeing wastewater is the wastewater discharged from printing and dyeing, wool dyeing and finishing, and silk factories that mainly process cotton, linen, chemical fiber and its blended products, and silk. The amount and quality of printing and dyeing wastewater vary depending on the type of fiber and processing technology. Among them, the amount of wastewater from printing and dyeing factories is relatively large. Each ton of textile printing and dyeing consumes 100 to 200 tons of water, of which 80% to 90% is discharged as wastewater. Printing and dyeing wastewater has the characteristics of large water volume, high content of organic pollutants, high alkalinity and large changes in water quality. It is one of the difficult-to-treat industrial wastewaters. The wastewater contains dyes, pulps, auxiliaries, oils, acids and alkalis, fiber impurities, sand substances and inorganic salts.

[0003] In order to improve the treatment effect of printing and dyeing wastewater, a treatment device is needed to treat a large amount of wastewater. For example, a printing and dyeing wastewater treatment device disclosed in Chinese patent CN218146254U includes an aeration tank, a deep treatment tank and a filter tank. The aeration tank, the deep treatment tank and the filter tank are connected through a pipeline provided with a water pump. The aeration tank is used to degrade organic matter in the printing and dyeing wastewater through aeration and biological reagents. Alkaline and weak alkaline resins are added in the deep treatment tank to deeply treat the organic matter in the printing and dyeing wastewater. The filter tank is used to remove solid particles in the printing and dyeing wastewater. The device also includes a control mechanism, and the control mechanism is electrically connected to the water pump. The printing and dyeing wastewater treatment device disclosed in the utility model can completely remove organic matter and colored substances in the printing and dyeing wastewater through biological degradation and chemical adsorption exchange, so that the printing and dyeing wastewater is better purified and meets the discharge standard.

[0004] However, there are still problems. When the device is treating wastewater, the wastewater needs to be circulated many times, and the colored substances in the wastewater need to be removed by degradation and chemical adsorption. This is not only time-consuming, but also the wastewater and the drug are not mixed sufficiently, resulting in a small amount of harmful substances remaining in the subsequently filtered wastewater. Therefore, a printing and dyeing wastewater treatment device is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a printing and dyeing wastewater treatment device, which has the advantage of good purification effect and solves the problem of excessive residual pollutants caused by insufficient stirring.

[0008] By adopting this technical solution, the stirring mechanism achieves the purpose of fully stirring and mixing the wastewater and the medicine, so that the wastewater can be purified more fully and the pollution degree of the wastewater is reduced.

[0009] Furthermore, a mounting frame is fixed on the outer surface of the servo motor, and the servo motor is fixed to the inner cavity of the working box through the mounting frame. Both left and right sides of the waterproof box are provided with movable holes adapted to a plurality of stirring rods.

[0010] By adopting this technical solution, the matching movable hole can not only leave enough movable space when the stirring rod is driven to rotate, but also avoid interference with the waterproof box.

[0011] Furthermore, the three transmission components are composed of an active bevel gear, two driven bevel gears and two limit plates. The active bevel gear is fixed on the outer surface of the driving rod, the two driven bevel gears are meshed with the active bevel gear and are respectively fixed to the stirring rods on the left and right sides, and the two limit plates are respectively fixed between the top wall and the bottom wall of the inner cavity of the waterproof box and are respectively penetrated by the stirring rods on the left and right sides.

[0012] By adopting this technical solution, the transmission component increases the vertical rotation force to several lateral rotation forces, thereby achieving the purpose of increasing the stirring efficiency.

[0017] Furthermore, a waste liquid tank is movably connected to the bottom of the tank body, a delivery pipe is connected between the tank body and the waste liquid tank, and the inner bottom wall of the filter bin is inclined with the left side higher and the right side lower.

[0019] Furthermore, the left side of the top of the tank body is connected to a waste liquid delivery pipe that penetrates into the inner cavity of the purification chamber, and the right side of the top of the tank body is connected to a drug delivery pipe that penetrates into the inner cavity of the purification chamber.

[0020] By adopting this technical solution, the drug delivery tube can directly replace manual addition of drugs, which is more convenient and more efficient.

[0021] Furthermore, an inspection door is hinged on the front of the working box, a heat dissipation hole is provided on the right side of the working box, and a mounting hole adapted to the filter is provided on the front of the tank body.

[0022] By adopting this technical solution, the heat dissipation holes can ensure that the working box is always at a normal temperature to avoid heat caused by long-term operation of the servo motor. The installation hole can remove the filter for cleaning after the device has discharged the wastewater, so as to block the remaining pollutants in the wastewater next time.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The printing and dyeing wastewater treatment device pours wastewater and drugs into the purification bin at the same time, starts the stirring mechanism, rotates the driving rod, drives several stirring rods to start rotating, and drives the stirring blades to fully stir the drugs and wastewater. After the drugs and wastewater are evenly mixed, the water outlet pipe is opened, and the drugs are filtered through the filter net and then discharged into the waste liquid tank, thus completing the treatment of the wastewater, achieving the purpose of good purification effect, and having higher wastewater treatment efficiency.
