Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a flocculation treatment device for wastewater after fluorite beneficiation. Background Art

[0002] Fluorite, also known as fluorspar, is a common mineral in nature. It can coexist with many other minerals and is produced in many places in the world. In the mining production process, it mainly includes crushing and screening, grinding, flotation, dehydration and drying, and tailings treatment. Flotation mainly includes roughing and concentrating. After concentrating, the resulting slurry needs to be transported to a high-efficiency concentrator for concentrating using a slurry pump. After concentration, wastewater will be generated. If the wastewater is discharged directly, it will not only cause environmental pollution, but also cause a waste of water resources. Therefore, it is necessary to treat and recycle the mineral processing wastewater.

[0003] The disclosure discloses a fluorite beneficiation wastewater treatment and reuse device with announcement number CN118811982A, which belongs to the technical field of wastewater treatment, and comprises a reaction tank, a liquid storage cylinder, a bottom cylinder, a transmission assembly and a float. The liquid storage cylinder is fixedly arranged in the reaction tank and a transmission shaft is rotatably installed inside the bottom cylinder. The piston is slidably arranged in the inner cavity of the liquid storage cylinder. The bottom cylinder is rotatably assembled in the reaction tank and one end is fixedly connected to the transmission shaft. A plurality of side cylinders for outputting flocculants are arranged on the bottom cylinder. The transmission assembly is assembled outside the liquid storage cylinder and is connected to the piston transmission. The float is slidably sleeved on the bottom cylinder and is linked to the transmission assembly. The present invention can quantitatively output flocculants according to the liquid level height by arranging a floating float on the bottom cylinder, thereby ensuring that the amount of flocculants matches the total amount of wastewater. While stirring the mixed liquid, the flocculants can be automatically replenished after the wastewater is treated, thereby eliminating the manual filling step and effectively improving the wastewater treatment efficiency.

[0004] During actual use, the fluorite beneficiation wastewater treatment and reuse device proposed in the above patent document only performs flocculation treatment on the wastewater to produce large flocs in the wastewater, but the wastewater still contains some small particles of impurities and dirt. The treatment equipment is unable to further filter the flocculated wastewater at the same time, resulting in insufficient and incomplete treatment of the fluorite beneficiation wastewater, affecting the subsequent recovery and utilization of the wastewater. Summary of the invention
