Description

Technical Field

[0001] This utility model relates to the field of dyeing and printing wastewater treatment technology, and more specifically, to a dyeing and printing wastewater recycling treatment device. Background Technology

[0002] Biological treatment of dyeing and printing wastewater is a common process in the dyeing and printing industry. During wastewater treatment, various pollutants are removed through biological treatment processes, and the wastewater is discharged or reused after meeting emission standards. Industrial wastewater is generated during the dyeing, printing, and finishing processes of textiles. This wastewater has high color, high concentration, and a large amount of suspended solids. The generated wastewater flows through a screen to trap large floating and suspended solids, and then enters the wastewater treatment plant's collection tank to adjust the water quality and quantity. Chemicals are added to the reaction tank to adjust the pH value, and then the wastewater is pumped to the primary sedimentation tank for coagulation and sedimentation to remove color and some organic matter and suspended solids. The effluent then enters the hydrolysis acidification tank. In the hydrolysis acidification tank, organic matter in the wastewater is decomposed by microorganisms, long-chain organic matter is degraded into short-chain organic matter, and recalcitrant substances are converted into biodegradable substances, thereby improving the biodegradability of the wastewater. The effluent from the hydrolysis acidification tank enters the aerobic biological oxidation tank for aeration and aerobic treatment. Under the action of aerobic microorganisms, organic matter in the wastewater is decomposed, removing most of the remaining organic matter in the wastewater. After the effluent passes through the secondary sedimentation tank to remove suspended solids, it is filtered to meet discharge standards or disinfected for reuse.

[0003] In response, Chinese patent application number CN218146275U discloses a wastewater recycling treatment device for dyeing and printing. The device includes a treatment tank comprising a hydrolysis acidification tank and an aerobic tank. Several biological packing materials are fixedly installed inside the hydrolysis acidification tank and the aerobic tank. A first sedimentation tank is fixedly installed on one side of the hydrolysis acidification tank. This utility model, by setting up the treatment tank, allows wastewater to be treated by adding chemicals in the first sedimentation tank. After sedimentation in the first sedimentation tank, the wastewater enters the second treatment tank through a water pipe. The hydrolysis acidification tank and the aerobic tank further treat the wastewater. The biological packing materials can better treat the wastewater. Then, the wastewater enters the second sedimentation tank through a water pipe, where workers add chemicals and perform secondary sedimentation treatment. This improves the practicality of the equipment, and the multiple treatments of the wastewater result in better purification effects, thus improving the working quality of the equipment. Furthermore, the multiple tanks reduce operating costs and effectively reduce operational risks.

[0004] However, in actual use, the effect of adding chemicals inside the sedimentation tank is poor, and the chemicals cannot be fully mixed with the wastewater, resulting in poor overall sedimentation. In addition, the subsequent return water tank cannot transport water in multiple groups during use.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a wastewater recycling treatment device for dyeing and printing. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dyeing and printing wastewater recycling treatment device.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a dyeing and printing wastewater recycling treatment device, comprising a sedimentation tank body, an inlet pipe installed on the left side surface of the sedimentation tank body, a first guide block installed on one side of the inner wall of the sedimentation tank body, a second guide block installed on the other side of the inner wall of the sedimentation tank body, and a first motor body installed on the top surface of the sedimentation tank body.

[0008] The first gear is installed at the output end of the first motor body, and the right side surface of the first gear is meshed with a second gear, and a rotating cylinder is installed inside the second gear;

[0009] A connecting ring is installed on the top surface of the rotating cylinder. A stirring shaft is installed on the outer surface of the rotating cylinder. Three sets of stirring shafts are provided. Discharge holes are evenly opened on the surface of the rotating cylinder.

[0010] Preferably, a auger conveyor is installed on the front surface of the sedimentation tank body, and a sludge thickening tank is provided at the end of the auger conveyor away from the sedimentation tank body, and a filter press is installed on the top surface of the sludge thickening tank.

[0011] Preferably, a hydrolysis acidification tank is connected to the right side of the sedimentation tank body via a pipe, and an aerobic tank is installed on the right side surface of the hydrolysis acidification tank.

[0012] Preferably, a decolorizing clear water tank is provided on the right side of the aerobic tank, and the hydrolysis acidification tank, the decolorizing clear water tank and the decolorizing clear water tank are all connected by pipelines.

[0013] Preferably, a conveying pipe is provided on the right side surface of the decolorizing clear water tank, and a recycled water tank is installed at the end of the conveying pipe away from the decolorizing clear water tank. A connecting pipe is installed on the right side surface of the recycled water tank.

[0014] Preferably, a tee is installed on the right side surface of the connecting pipe, and a solenoid valve is installed on the top surface of the connecting pipe.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this utility model, through the arrangement of a sedimentation tank body, an inlet pipe, a first guide block, a second guide block, a first motor body, a first gear, a second gear, a connecting ring, a rotating cylinder, a stirring shaft, a discharge hole, a auger conveying cylinder, and a sludge thickening tank, wastewater is first transported into the sedimentation tank body through the inlet pipe. The design of the first and second guide blocks guides impurities in the wastewater. Then, a precipitant is added into the connecting ring, and the first motor body is started. The first motor body drives the first gear to rotate, and then the first gear meshes with the second gear. The first gear drives the second gear to rotate, which in turn drives the rotating cylinder and connecting ring to rotate. This, in turn, drives the stirring shaft to rotate. As the cylinder rotates, the precipitant flows out from the discharge hole, ensuring even mixing between the precipitant and wastewater. This improves the sedimentation effect of impurities in the wastewater. The precipitated impurities are then transported to the sludge thickening tank via a auger conveyor inside the auger conveyor. A filter press then processes the impurities in the sludge thickening tank into sludge cakes. Finally, the sludge thickening tank is opened, and the sludge cakes are discharged, demonstrating the practicality of the design.

[0017] 2. In this utility model, by setting up a hydrolysis acidification tank, an aerobic tank, a decolorization clear water tank, a conveying pipe, a recycled water tank, a connecting pipe, a T-pipe, and a solenoid valve, the wastewater inside the sedimentation tank is continuously transported through the pipeline to the hydrolysis acidification tank, the aerobic tank, and the decolorization clear water tank for filtration treatment. After filtration in the hydrolysis acidification tank, the aerobic tank, and the decolorization clear water tank, the water is transported through the conveying pipe to the recycled water tank for recycling. Then, the water is transported through the connecting pipe to the T-pipe, which can transport water in three directions. Subsequently, the connecting pipe can be opened by the solenoid valve, so that the water in the recycled water tank can be recycled by simply opening the solenoid valve, thus demonstrating the functionality of the design.

An aerobic tank 16 is installed on the right surface of the hydrolysis acidification tank 15. A decolorization clear water tank 17 is set on the right side of the aerobic tank 16.

A solenoid valve 22 is installed on the top surface of the connecting pipe 20. After being filtered by the hydrolysis acidification tank 15, the aerobic tank 16 and the decolorizing clear water tank 17, the water is conveyed to the interior of the reclaimed water tank 19 through the conveying pipe 18 for recycling. Then, the water is conveyed to the interior of the three-way pipe 21 through the connecting pipe 20. The three-way pipe 21 can convey water in three directions. Then, the connecting pipe 20 can be opened by the solenoid valve 22. Solenoid valve 22 can be opened when the water in the reclaimed water tank 19 is recycled.
