Description

Method for Separation of Particles in Aqueous Slurry

Field of the Invention 5

The invention relates to a process for separating particles in an aqueous slurry as defined in the preamble of independent claim 1.

The present invention relates to a baffle separator or baffle basin or similar separator or baffle device (hereinafter referred to as a "baffle basin") for separating solid particles in an aqueous slurry or pulp into two or more fractions containing particles of different size and density.

Many sizing and grading methods utilize the dead weight of the 15 solids in the aqueous slurry, whereby the inlet feed containing the material encounters an upwardly flowing water flow. Size and / or density variations result in heavier particles falling to the lower level of the anti-settling basin and lighter particles being raised to the overflow level of the anti-settling basin, thereby providing the desired separation.

The operation of the so-called dewatering basins is based on the even distribution of a controlled amount of floating water into the interior of the damper separator body, the floatation water dispenser being arranged inside the damper separator body. Usually, the floating water is pumped into the floating water pipes of the floating water dispenser only from one side, but if the water is "dirty" and contains, for example, a lot of finely divided solid material, the floating water pipes become clogged because the finely divided material This clogging then progresses gradually towards the inlet end of the float pipes, and relatively shortly the feed of the float water to the hold-down basin is skewed and operation becomes poor. In some cases, 30 floating water is pumped into the floating pipes at both ends, but then clogging begins at the center of the floating pipes.

Brief Description of the Invention 2

The object of the present invention is to solve the problem identified above.

The method of the invention for separating particles in an aqueous slurry is known from the definitions of independent claim 1.

Preferred embodiments of the method are defined in dependent claims 2-12.

The invention is based on removing a portion of the floating water supplied to the floating water dispenser by using a floating water discharge means in fluid communication with the floating water dispenser. This means, for example, that a certain amount of floating water is supplied to the floatation water dispenser. For example, this amount may be twice the amount actually used for floating in the baffle separator so that the other half only flows through the float pipes of the float water dispensing means in the baffle separator. Thereby, the flow rate in the floating water pipe system 15 is high or high enough to keep the floating water pipes clean by effectively transporting the finely divided solid material through the floating water pipes. In this way, an arrangement can be created which does not require, or very rarely requires, cleaning of the float pipes by the arc.

In the method and in the baffle separator, some dirty floating water, that is, floating water containing particles, may be used. The new arrangement is substantially useful in cases where dirty circulation water is used, e.g. from waste water ponds, or a thickener. For environmental reasons, this is the most common situation in the industry today.

In the proposed system, the pipes could also be cleaned, if necessary, only by temporarily increasing the water flow rate. Opening the unit for cleaning would not be necessary at all.

In one embodiment of the invention, both the inlet pipe for supplying the float water to the float water dispenser and the return pipe for directing the float water from the float water outlet means are provided with a flow measuring device, e.g. a flowmeter, to measure the flow before the baffle separator. The difference between the flows naturally flows into the interior of the baffle separator. In this embodiment, the amount of flushing water entering the interior of the baffle separator body and the amount of floating water flowing through the interior of the baffle separator body respectively can be controlled by a valve means, e.g. an automatic valve in the return pipe.
