Description

Technical Field

[0001] This invention relates to the field of thickener technology, specifically a deep cone thickener with rapid self-regulation of underflow concentration. Background Technology

[0002] The deep cone thickener, with rapid underflow concentration self-regulation, is a device used in slurry treatment designed to increase the solids content of the slurry by increasing the concentration of mineral particles. The deep cone thickener features a steeper cone than traditional thickeners, facilitating faster settling and better dewatering. Underflow concentration self-regulation mainly involves the following aspects: Underflow concentration is typically measured using online concentration sensors, which provide real-time concentration data to the control system. Based on the measured concentration data, the control strategy can automatically adjust the equipment's operating parameters, such as dosage, flocculant type and concentration, and feed rate, to achieve rapid concentration control.

[0003] When applying for this invention, the applicant, through a search, discovered a Chinese patent disclosing a "Deep Cone Thickener with Rapid Self-Regulating Underflow Concentration," application number "CN201810272655.2." This patent primarily utilizes high, medium, and low-level circulation to rapidly adjust the underflow concentration, satisfying both high-concentration underflow requirements for filling underground voids and high-concentration underflow requirements for filling surface subsidence areas. Furthermore, it enables rapid switching between high and low concentrations, thus avoiding the cost waste of using two deep cone thickeners with different underflow concentrations and shortening the concentration adjustment time, thereby improving efficiency. Simultaneously, this invention enables both underground tailings paste filling and high-concentration surface discharge, effectively treating solid waste such as tailings while avoiding void hazards. This thickener is characterized by high efficiency, environmental friendliness, and strong practicality, providing efficient and reliable equipment for paste technology and possessing significant application value. It is suitable for metal and non-metal mining enterprises; however, during use, the device exhibits a slow adjustment speed due to the overall concentration adjustment from top to bottom. Therefore, based on the applicant's invention, a deep cone thickener with rapid self-regulation of undercurrent concentration has been invented, solving the problem of slow concentration adjustment speed.
