Description
Technical field
The present invention relates to a kind of continuously casting for metal casting and equipment of hot rolling field more particularly to the turbid rings of compact
Water treatment station.
Background technique
Continuous casting turbid circulating water occurs mainly with directly cooling fan-shaped section spraying cooling, folder rod, frame, flame cutting machine and slab
The technical process such as granulating steel slag, quick water cooling plant and hot scarfing machine.Hot rolling sewage circulating water occur mainly with various rolls it is cooling,
The technical process such as rollgang cooling, high pressure descaling (rushing iron scale and flushing cinder).Turbid circulating water not only water temperature during generation
It can increase, water quality also will receive pollution.Major pollutants in muddy water are the iron scale solid phase particles and various greasy dirts to suspend.
Continuous casting and the common water treatment technological process of hot rolling sewage circulating water at present are as follows: 1. user's return water → iron sheet ditch → whirling well
Or scale pit → electrochemical deoiling settling vessel → hot-tub (→ sand filter) → cooling tower → water cooling pond → water supply to user；2. sand filtration
Device backwash draining, chemical oil remover base sludge → sludge sump → sludge concentration tank → dewaterer → mud cake outward transport.

Mud treatment system can be with continuous operation；
(14) the mud liquid of centrifugal dehydrator 9 is from turbid circulating water system whirling well or 11 overcentre of body refuse slot of scale pit with the side of drop
The slag muck of formula inflow body refuse slot 11.
(15) when 15 numerical value of level-sensing device of body refuse slot is higher than body refuse trough level ground 2m, corresponding centrifugation is de- above the body refuse slot
Water dispenser mud liquid discharge outlet electrically operated valve 14 is opened, and when material position count value is lower than body refuse trough level ground 1m, electrically operated valve 14 is closed.
(16) medicine machine 10 is respectively to chemical oil remover 2,8 dosing of sludge concentration tank.
(17) cooling tower 5 forces water for cleaning of the sewerage as dewaterer 9, and redundance is used for the cleaning of body refuse slot 11
Use water.
(18) entrance that every lattice body refuse slot 11 is passed in and out for haulage vehicle is equipped with close to switch 19, has been received when close to switch
When haulage vehicle entering signal, the centrifugal dehydrator mud liquid discharge outlet electrically operated valve 14 of the corresponding lattice is automatically closed, is opened when close
When pass has received haulage vehicle leaving signal, restore the centrifugal dehydrator mud liquid discharge outlet electrically operated valve 14 and the lattice of the lattice again
