SU1247439A2 - Vortex purifier for cleaning aqueous suspension of fibre pulp - Google Patents

Description

This invention relates to vortex cleaners, used in pulp and paper and other industrial sectors for the purification of BonoKHt CToii aqueous suspensions.

The aim of the invention is to increase the cleaning efficiency by eliminating the entrainment of particles of heavy inclusions with a stream of purified mass.

FIG. 1 shows a vortex cleaner 5 on. 2 is a section A-A. In FIG. one ; in fig. 3-5 - type B in FIG. 1, variants; in fig. 6 .- section BB in FIG. 1; in fig. 7 - section G-Y in FIG. four; in fig. 8 is a section d-d in FIG. five.

The vortex cleaner includes a cone-shaped separation chamber 1, the ends of which are closed by covers 2 and 3. In the zones of the smaller and larger bases of the chamber 1, respectively, tangential nozzles 4 and 5 are placed for supplying the initial suspension and withdrawal of waste. An axis of the device in the lid 3, which covers the large base of the chamber 1, is fixed by a nipple 6 for outputting mass. Between the chamber 1 and the nozzle 6, the guiding elements 7 are fixed, made in the form of blades of straight or angular shape, set at an angle

to isy camera 1 separation. The guiding elements 7 form between them channels 8 into the cavity 9, which is connected to the nozzle 5 to discharge waste.

The initial suspension of pulp under pressure through the pipe 4 is tangentially fed into the inside of the cone-shaped chamber 1 of senation. Under the action of centrifugal forces, when moving but the spiral-helical trajectory, heavy extraneous inclusions (waste) are thrown against the wall: chambers 1 and move axially towards the inlet pipe. Extraneous inclusions, which run along a spiral-helix trajectory, through channels 8, formed by guide elements 7, enter the cavity 9, from which they are discharged through pipe 6. Guide elements 7 and formed by them oriented in systematic way of waste movement Canapés 8 interfere with the appearance of reverse flows slurry boiling to drive the entrainment of particles from the purified waste mass, thereby increases the efficiency of cleaning the slurry and decreases the flow resistance of the cleaning agent.
