Embodiment Construction

[0018] In the following, reference will be made to Figure 2a and 2b The operating principle of bottom dilution in a vortex cleaner according to a first advantageous embodiment of the invention is described. Figure 2a and 2b The bottom diluter pipe 6 is shown, which comprises a flow channel 7, the first end 7a of which flow channel 7 is provided with the inlet 8 for dilution water, for supplying dilution water to the bottom diluter pipe 6, the flow of the bottom diluter pipe The second end 7b of the channel 7 is provided with an outlet 9 for discharging the dilution water from the bottom diluter pipe 6 to the separation cone 5 of the vortex cleaner. The diameter of the flow channel 7 is not necessarily constant, it may include for example Figure 2a and 2b The taper shown is such that the diameter of the second end 7b of the flow channel 7 is greater than the diameter of the first end 7a of the flow channel. The outlet 9 can also be an opening.

Abstract

The invention relates to a bottom diluter duct (6) of a vortex cleaner comprising at least a flow channel (7), a dilution water inlet (8) for supplying dilution water to the flow channel (7) ) and an outlet (9) for discharging the dilution water from the bottom diluter pipe (6) into the vortex cleaner (1). The bottom diluter conduit (6) also comprises means (10) for controlling the flow of dilution water, arranged to be movable between a first position and a second position. In the first position, the outlet (9) is closed, and in the second position, the outlet (9) is opened, wherein the outlet (9) is set to act according to the inlet pressure (P2) of the dilution water for controlling the dilution water in the vortex deslagging The ratio of the pressure (P1) of the device (10) to the flow in the device opens. The invention also relates to a vortex cleaner and a method for supplying dilution water to the vortex cleaner through the bottom diluter conduit (6).

Description

technical field [0001] The present invention relates to a bottom diluter structure of a vortex cleaner comprising at least a flow channel, a dilution water inlet for supplying dilution water to the flow channel and for discharging dilution water from the bottom diluter structure into the vortex cleaner export. The invention also relates to a vortex cleaner having a pulp inlet for supplying pulp into the vortex cleaner, a separation cone for separating impurities from the pulp, an impurities outlet and a pulp outlet. Furthermore, the present invention relates to a method for the bottom diluter of a vortex cleaner, in which method dilution water is supplied to the bottom diluter pipe, and the dilution water supplied to the bottom diluter pipe then passes through an outlet in the bottom diluter pipe Discharge to vortex cleaner. Background technique [0002] Vortex cleaners are used, for example, in the process of processing recycled pulp for papermaking, the purpose of which ...
