Description

Technical Field

[0001] The utility model relates to the technical field of purification devices, in particular to electro-flocculation purification equipment for printing and dyeing wastewater. Background Art

[0002] Printing and dyeing wastewater refers to the mixed wastewater discharged from various processes in the printing and dyeing process. Water is a natural resource that is easily polluted but can be recycled. With the continuous growth of population and economic development, coupled with the increasingly serious water pollution, the amount of available water resources is increasingly scarce, causing a water crisis. The purpose of printing and dyeing wastewater treatment is to remove various harmful substances in the wastewater, prevent environmental pollution, and enable water to be reused. However, today's purification devices use electrocoagulation and electrolysis to react with organic matter in the wastewater to form insoluble precipitation, but the drainage pipe is installed at the bottom of the container. Long-term precipitation at the bottom is easy to block the drainage pipe at the bottom of the container, causing slow drainage or even cessation of discharge.

[0003] Therefore, a printing and dyeing wastewater electrocoagulation purification device is proposed. Utility Model Content

[0004] The utility model aims to solve the defect that the sediment in the prior art may cause blockage, and proposes an electro-flocculation purification device for printing and dyeing wastewater.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A printing and dyeing wastewater electro-flocculation purification device comprises a shell, a horizontal plate is fixedly installed on the top of the inner wall of the shell, a screw rod 2 is rotatably installed on the bottom of the horizontal plate, a circumferential thread of the screw rod 2 is connected with a perforated plate, a positioning box is fixedly installed on the top of the horizontal plate, a motor 2 is fixedly installed on the top of the positioning box, and a screw rod 1 is rotatably installed on the side of the positioning box, a fixed block is connected with the circumferential thread of the screw rod 1, and two penetrating guide rods are slidably connected to the bottom of the fixed block, a scraper is fixedly connected between the bottoms of the two guide rods, and the bottom surface of the scraper is in contact with the top of the perforated plate; a transmission assembly is arranged in the positioning box, and the motor 2 drives the screw rods 1 and 2 to rotate through the transmission assembly;

[0007] The electrode plate is installed at the bottom of the inner wall of the shell and is used to react and combine with organic matter in the wastewater inside the shell to form insoluble precipitation.

[0008] In one possible design, a support frame is fixedly installed on the side of the shell, a purification barrel is fixedly installed inside the support frame, a stirring rod is rotatably installed on the top of the inner wall of the purification barrel, a motor 1 is fixedly installed on the top of the purification barrel, the output shaft of the motor 1 passes through the purification barrel and is fixedly connected to the stirring rod, a first connecting pipe is fixedly installed on the bottom of the purification barrel, one end of the first connecting pipe is fixedly connected to the shell, and a filter plate is slidably installed on the inner wall of the purification barrel.

[0013] In the present application, printing and dyeing wastewater enters the purification barrel through the water inlet on the side of the purification barrel, the motor 1 is started, and the stirring rod rotates slowly. Impurities and organic matter in the wastewater that are larger than the filter holes on the filter plate are precipitated on the top of the filter plate, and impurities and organic matter that are smaller than the filter holes on the filter plate enter the shell along the connecting pipe 1 at the bottom of the purification barrel. The anode and cathode of the electrode plate react and combine with the organic matter in the wastewater to form an insoluble precipitate, which is precipitated on the surface of the orifice plate.
