Description

Technical Field

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

[0002] Wastewater harmless treatment refers to the process of removing or converting harmful substances in wastewater into harmless substances through a series of physical, chemical and biological treatment processes, so that it meets the standards for discharge or reuse.

[0003] Patent CN 213253280 U discloses a chemical waste liquid classification and recycling treatment device, which includes a cylinder and a filter device. A support is fixedly connected to the surface of the cylinder, a cylinder cover is inserted into the inner wall of the cylinder, a feed pipe is fixedly connected to the upper surface of the cylinder cover, and a discharge pipe is fixedly connected to the surface of the cylinder. Currently, most chemical waste liquids contain a large number of large particles of impurities. When treating waste liquid, the impurities collide with the recycling device, causing damage to the recycling equipment and affecting its service life. The application of this device effectively avoids the above problems and improves the stability of the equipment.

[0004] However, the device has a stirring blade that is only located inside the cylinder, which means that the filter cylinder cannot be stirred during the filtration of wastewater. Large particles of impurities left in the filter cylinder can easily accumulate or adhere to the filter cylinder, thus clogging the filter holes and affecting the wastewater discharge rate. To address this issue, a harmless treatment device for dyeing and printing wastewater is proposed to solve the problem that existing treatment devices are prone to clogging due to accumulation of impurities, which affects wastewater discharge.

[0022] Furthermore, the limiting block 23 is fixedly connected to the filter plate 5. When the filter plate 5 is located in the inner cavity of the filter cylinder 3, the upper cleaning brush 11 is attached to the filter plate 5, and the lower cleaning brush 11 is attached to the bottom of the inner cavity of the filter cylinder 3.

[0023] Furthermore, a valve is provided between the liquid guiding tank 16 and the reaction chamber 17. The reaction chamber 17 is cylindrical. An inlet pipe 15 is provided on one side of the main body 1 of the processing device. Both the outlet 13 and the inlet pipe 15 are interconnected with the reaction chamber 17.
