Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a cold rolling wastewater recycling device. Background Art

[0002] Cold rolling wastewater is wastewater generated during the production process of cold rolling mills of steel enterprises. Its main components are acidic wastewater, emulsions and oils. With the improvement of water treatment technology in recent years, cold rolling wastewater has achieved standard discharge, but due to its large volume and complex components, its reuse and zero-discharge technology have not been widely promoted. Even if a few projects have reused wastewater, the reuse rate is not ideal.

[0003] The patent with publication number CN 217555957 U discloses a stainless steel cold rolling acid wastewater treatment device, which includes a treatment tank, a water inlet pipe, a baffle and a guide pipe. The water inlet pipe is arranged on the upper end of one side wall of the treatment tank, and the baffle is fixed in the treatment tank. The device drives the stirring shaft to rotate through gear 2, thereby accelerating the reaction rate of the acid solution and the drug, and the two sets of stirring mechanisms share a motor, which can effectively reduce the energy consumption of the device, ensure the performance of the device, and improve the practicality of the device. However, the device has the problem of directly introducing the cold rolling wastewater into the treatment tank, and then putting the treatment agent to make the impurities settle. After sedimentation, the purified waste liquid is pumped away by a pump, and then the remaining sediment is discharged. However, the deposited wastewater impurities cannot be guaranteed to always be located at the bottom of the sedimentation chamber. As a result, it is easy to pump impurities into the purification chamber when the wastewater is pumped by the pump, and the extraction pipe does not reach the bottom of the sedimentation chamber, making it difficult to pump out all the purified wastewater. This easily leads to the discharge of wastewater when the sediment is discharged, resulting in unsatisfactory wastewater treatment results. Therefore, a cold rolling wastewater recovery and reuse device is proposed to solve the problem of poor wastewater treatment capacity of existing wastewater recovery and reuse devices.

[0027] Furthermore, the connecting pipe 8 is interconnected with the pump body 9 and the bottom of the processing chamber 3, and the pump body 9 is interconnected with the recovery chamber 2. The wastewater filtered out of the processing chamber 3 will gather at the bottom of the processing chamber 3. The connecting pipe 8 can be used to completely draw the wastewater at the bottom of the processing chamber 3 into the recovery chamber 2 to wait for use or further treatment.

[0028] Furthermore, a fixing plate 12 is fixedly connected to the top of the inner cavity of the processing frame 5 , and a motor 13 is fixedly connected to the top of the fixing plate 12 .

[0029] Furthermore, a stirring rod 14 is provided inside the processing frame 5, and the outer ring of the stirring rod 14 is fixedly connected to a stirring plate 15. The output shaft of the motor 13 passes through the fixed plate 12 and is fixedly connected to the stirring rod 14.
