Deep Cone Thickener Tanks

What is a Deep Cone Thickener Tanks?

The Deep Cone Thickener Tank is a plant process equipment used in separating and concentrating solid-liquid mixtures in mineral processing plants, wastewater treatment facilities, and other industrial processes. This tank features a cone-shaped bottom that allows efficient sedimentation and thickening of fine particles and slurry. During entry of the mixed slurry into the tank, the solids settle to the bottom due to gravity and form a dense cake; the clarified liquid overflows from the top. The deep cone design of the tank provides an increased settlement area and steep slope angle, facilitating the separation and thus assuring maximum concentration of solids in the underflow. The Deep Cone Thickener Tanks find wide application in processes where thickening, dewatering, or separation of solid-liquid is required with high efficiency in attaining the desired levels of concentration and clarity of liquids.

The mixed slurry in the process is received into the tank by the Deep Cone Thickener Tank; commonly, this would involve ore slurries, tailings, or wastewater. As the slurry enters the tank, gentle upward water flow and deep settling zone inside the tank make the solids settle down at the bottom of the cone. These concentrated solids then form a thick sludge or cake at the bottom of the tank, while the clarified liquid rises towards the top, overflowing through the launder. Such a steep angle for the cone would then provide better separation of the solids from the liquids and help to attain a high solid concentration in the underflow. Deep Cone Thickener Tanks, owing to their capability of thickening materials effectively and dewatering, are very useful in industries. They offer cost-effective solutions for the solid-liquid separation process and manage waste streams and precious resources.

Deep Cone Thickener Tanks Components

1. Tank Structure

The Deep Cone Thickener basically has a conical-shaped tank structure, which enables efficient sedimentation and thickening of solid-liquid mixtures. This design of the tank is such that it provides a large settling area for the separation process. As the mixed slurry enters the tank, the solids settle down due to the design of the cone at the bottom and form a dense underflow of solids. Such design allows the handling of a large amount of slurry and ensures that the separation is optimized to effectively thicken and settle.

2. Feed Inlet

The feed inlet is where the mixed slurry flows into the tank of the Deep Cone Thickener. It is that point at which the slurry, containing solid particles and liquid, is fed into the thickener for processing. The feed inlet plays a very vital role in creating the thickening process by feeding the slurry into the tank, where due to gravitational force, solids settle at the bottom of the tank. The feed inlet therefore must be properly controlled and managed to modulate the flow of slurry into the tank for effective and optimal thickening performance in industrial applications.

Deep Cone Thickener Tanks Usage Area

Mining Industry

Deep cone thickener tanks find key applications in the mining industry for mineral processing. Such a kind of tank, in mining, is mainly used to separate mixtures of solid-liquids such as ore slurries, tailings, and mineral concentrates. These tanks use the deep cone design to efficiently carry out thickening and dewatering of mining slurries, hence providing assurance for the extraction of valuable minerals from the materials processed. High efficiency and effectiveness for Deep Cone Thickener Tanks make them indispensable in the optimization of mineral recovery processes and the sustainable management of mining waste streams.

Wastewater Treatment Plants

Deep Cone Thickener Tanks are also normally utilized in wastewater treatment plants to help in the separation and clarification of sludge and liquid waste materials. These tanks are used in concentration and separation of solid-liquid phases in wastewater treatment plants to ensure that solids in the liquid phase are removed for effective treatment and subsequent disposal. Deep Cone Thickener Tanks in wastewater treatment will, therefore, enable industries to effectively manage their wastewater and treat it to reduce the impact on the environment, thereby meeting stringent regulatory standards that govern the discharge of wastewater into the environment. Such versatility and reliability of these tanks ensure their place as vital components of wastewater treatment plants to ensure water and environmental quality.

How Does a Deep Cone Thickener Tank Work?

A Deep Cone Thickener Tank functions on the basis of gravity to efficiently separate and thicken mixtures of solids and liquids. The mixed slurry, when it enters the tank, finds space for settling to take place because of the deep cone structure. Solids in the slurry settle to the bottom of the tank due to gravity, developing into a dense underflow of concentrated solids, while the clarified liquid rises to the top and overflows from the tank. With its steep angle, the cone offers an extensive settling area, hence efficiently sedimenting and separating solids from liquids. Afterwards, the thickened slurry is discharged from the tank, and the separated liquid is usually further processed for final treatment or disposal.

Working Principle: The Deep Cone Thickener Tanks work on the principles of sedimentation and clarification using a deep cone design. These tanks increase the setting area by a huge margin and steepen the slope angle to effectively concentrate solids through excess liquid removal from the mixture. The combination of gravity and the tank design enables the formation of a thickened underflow that is high in solid content, providing maximum thickening efficiency. Deep Cone Thickener Tanks are thus core to most industries that involve solid-liquid separation and concentration processes, offering a reliable solution to deal efficiently with slurries, tailings, and other mixed materials.
