Abstract

The invention relates to the field of water purification and the thickening of sediments of metallurgical and mining industries and allows to increase the efficiency of purification of the suspension. The apparatus includes a housing with devices for supplying and discharging the treated fluid. The tank for accumulating sediment is equipped with an additional shaft (DV) with blades and a valve mounted on the lower end of the shaft. The coupling half serves as a connecting element between the central shaft and the Far East. When the apparatus is operated, the DW can move in the vertical direction to a distance of 0.5-0.7 of the height of the central shaft. Rotation of the active ingredient ensures loosening of sediment in the tank and thus facilitates its removal from the apparatus. The conditions created increase the efficiency of water clarification and the performance of the entire apparatus. 2 Il. with I (L

The invention relates to the treatment of water and can be used in the treatment of wastewater and the thickening of sediments of metallurgical and mining industries.

The purpose of the invention is to increase the cleaning efficiency.

FIG. 1 shows the proposed apparatus, a vertical section; in fig. 2 — node I in FIG. one.

The apparatus consists of a housing 1 with tangential nozzles 2, a diaphragm 3, a tray 4 for collecting clarified water, a tank 5 for collecting and accumulating sludge, a truss 6, a central shaft 7 with rotation mechanisms 8 and lifting 9. The device is equipped with capacitor 5 For accumulation of sediment by an additional shaft 10, which enters with its upper end into the central shaft 7 and is equipped with brackets 11, on which is mounted a gear coupling half 12, which surrounds the central shaft 7 and is facing down. The upper end of the additional shaft 10 is equipped with a toothed coupling half 13 facing upwards. The half coupling 13 is enclosed by the brackets 11. At the lower end of the central shaft 7, a cap 14 is mounted, covering the shaft coupling assembly. The additional shaft 10 is equipped with a valve 15 and blades 16.

The maximum possible distance between the coupling halves 12 and 13 of shafts 7 and 10 is 0.5-0.7 and the lift height of the central shaft 7. The selection of the distance between the coupling halves is determined from the conditions for ensuring the operation of the apparatus and ranges from Ai (0.5) to 2 (0.7) where the teeth are half-coupling and h. (Н - height of the central shaft lift 7 d - valve diameter 15).

The device works as follows.

Water containing suspended substances enters the housing 1 through tangential nozzles 2. The clarified water exits through the hole in the diaphragm 3, enters the tray 4, from where it is diverted to repeated use. The sediment falls to the bottom of the apparatus and the farm 6, driven by the rotation mechanism 8 through the central shaft 7, is scooped into the tank 5. In the sludge accumulation mode, the additional shaft 10 is in the lower position, whereby the valve 15 closes the sludge port. The precipitate accumulates and condenses in the tank 5.

The central shaft 7 is also in the lower position, in connection with which the coupling 13 does not engage with the coupling half 12 and rotates freely in the space between the brackets 11. When removing the draft, the central shaft 7 rises. Due to the fact that the distance between mfts 12 and 13 is 0.5-

0.7 lifting height of the central shaft 7, clutches 12 and 13 are engaged, the additional shaft 10 located in the sludge accumulation tank 5 also rises, and the valve 15 opens the sludge port and the additional shaft 10 also begins to rotate. At the same time, the blades 16 slightly loosen the sediment, increasing its transportability, and direct it to the slurry pipe.

The presence of a cap 14 enclosing the shaft joint assembly in the form of two half-couplings prevents it from being directly suspended, suspended solids, which reduces abrasive wear of parts.

The presence of valve 15 allows accumulation of sediment in vessel 5, where it is compacted. In view of the fact that the supplementary shaft 10 is adapted for angular movement with respect to the central shaft, it is possible to move the sediment to the tank 5 and at the same time create conditions in this tank to seal the sediment.

Due to the possibility of axial movement of the shafts, as well as the fact that the distance between the coupling halves is 0.5-0.7 of the lifting height of the central shaft 7, when the latter is lifted, the lower auxiliary shaft 10 rises, opening an opening to remove sludge.

The presence of the coupling halves 12 and 13 also ensures the rotation of the additional shaft 10 in the raised state. The presence of blades 16 on the additional shaft contributes to the loosening and removal of sediment.

Thus, the proposed apparatus makes it possible to increase the efficiency of the separation of the suspension, to improve the conditions for clarifying the treated water and ultimately to increase its productivity as a whole.
