Description

133336

The invention relates to the separation of liquid biphasic suspensions and T-B is used in the following areas: industrial concentration for wastewater and natural water treatment, classification of BSSK-solids in solid liquids.

The aim of the invention is to understand the effectiveness of cleaning liquids from suspended solids.

In Fig „1 the proposed settling tank is shown schematically; a general view; in Fig. 2 - section A-A in Fig. 1

The sump contains a camera 1pulka block 2 5 STATES from round discs (shelves) Zo Chamber 1 is connected to the inlet suspension 4 and the clarified suspension in outlet 5 through the soothing chambers 6 and 7 In the disk 3 in the middle there is an opening 8 to remove sediment A partition 9 is attached to the disk 3 in the form of a spiral. A circular partition 10 is fixed to the periphery of the disk. Between the disks 3 there are mounted bushes 11 which fasten all the disks to unit 2. Shelf unit 2 is rotated through a gearbox 12 by an electric motor 13 ° In the stilling chamber 6, a V-shaped deflection element 14 is set.

The sump works as follows: nm way.

The contaminated water enters through the nozzle 4 into the calming chamber 6 where the fluid flow is stabilized, is evenly distributed over the entire area of the cross section of the chamber 1, and then calmed down at a slow speed into the inter heap space of the shelf unit 2 organic and mineral particles are deposited in the inter-shelf space under the gravitational influence on the upper side of the disks (shelves) 3 "

The precipitated solids form a layer of sediment9 which is impacted. force of gravity moves down the shelf.

The advancement of sediment down the shelf is limited by a partition (groove) 9, completed in the form of spirals; and the dividing wall (groove) 10 D1-5ski 3 is constantly rotated by the electric motor 13 and the gearbox 12 in such a way that the sediment accumulating on the inner side of the partitions 9 and 10s is displaced to the center of the disks

3, 11 having reached the middle of the disk, the sediment falls into the bottom of the tank 1 1, through which it is removed from the sump

Preventing sediment moving down the hubs 11 into the mezdisc space (working area) through the pups, forming an ee when attaching the sleeves to the ihrny part of the disks 3, is ensured by the fact that the sleeves in the lower part are made conical the upper bushing enters the underlying bushing,

Floor block 2 is inclined to the horizon at the angle that ensures efficient and reliable operation of the sump by turning the whole device around its horizontal axis. Camera 1 is circular in plan so that riojiO4: ibri :. block 2 rotates freely in it. Dschi 3 it is advisable to cast} 1: whether to make from smooth r i dg-C fob material material, and spiral and peripheral partitions 9 and 10 to be made in the form of milled or grooves provided in cast form.

Compared with the prototype, the proposed invention PS eliminates the quality of cleaning by more complete isolation :; from the liquid suspension of suspended solids and selection of the most rational angle of inclination of the shelf units and uniform flow rate of the clarified liquid in the working zone of the settling tank.
