Wastewater purification and recovery device for steel strip rust removal

Abstract

The invention discloses a wastewater purification and recovery device for steel strip rust removal, the device comprises a support, a sterilization tank, a neutralization tank, a sedimentation tank and a standing tank are sequentially and fixedly arranged on the support, two adjacent ones of the sterilization tank, the neutralization tank, the sedimentation tank and the standing tank are connected through round pipes, one end of the sterilization tank is provided with a water inlet pipe in a penetrating manner, and one end of the standing tank is provided with a water outlet pipe in a penetrating manner. A sterilization assembly is arranged in the sterilization tank, a stirring assembly is arranged at the top of the neutralization tank, notches are formed in one side of the sterilization tank, the sedimentation tank and the standing tank, a baffle is fixedly connected to one side of each notch, a transmission assembly is arranged in each baffle, a quarter gear is arranged at the output end of each transmission assembly in a meshed mode, and each quarter gear is rotationally matched with the corresponding baffle. A rack is slidably arranged on one side of each notch and engaged with the transmission assembly, and a filter plate is fixedly connected to one side of the rack, the structure is reasonable, and the problems that impurities in the purification equipment are difficult to take out and the filter plate is difficult to clean are solved.

Description

technical field [0001] The invention relates to the technical field of waste water treatment equipment, in particular to a waste water purification and recovery device for derusting steel strips. Background technique [0002] Wastewater treatment is a technology that uses physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and achieve wastewater recovery, reuse, and full use of water resources. [0003] The steel belt will produce a large amount of waste liquid during the derusting operation. When the existing waste liquid purification treatment equipment processes the waste liquid, it will filter the waste liquid every step of the treatment, so as to remove impurities and filter the waste liquid once. The operation usually uses a filter plate. The filter plate of the existing equipment is clamped inside the equipment, which makes it difficult to remove the impurities falling on the filter plate, and the filter plate is trouble...
