Description
Technical field
The utility model belongs to the continuous cast mold soft water cooling system that steel plant use.
Background technology
The soft water cooling system is most important for continuous cast mold, industrial soft water carries out heat exchange by copper plate of crystallizer or plumbers shed ground connection and molten steel in mold and takes away part heat in the molten steel, guarantee that the molten steel that leaves the crystallizer cavity can form the base shell with certain geometric shape and sufficient intensity, and then play and support the core molten steel to the effect that casting blank outer cover produces static pressure, finally satisfy the industrial continuous production requirement.This is the basic functions designing requirement of crystallizer soft water cooling system.But at the northern China cold district, because existing crystallizer cooling system does not have backwash and purges function, often cause crystallizer generation bursting by freezing phenomenon, influence is normally used.
The utility model content
The purpose of this utility model is to provide a kind of continuous cast mold soft water cooling system, and it is simple in structure, can satisfy the cooling requirement of crystallizer, can carry out backwash and purge operation crystallizer again, prevents the crystallizer bursting by freezing, guarantees that crystallizer normally uses.
The purpose of this utility model is achieved in that a kind of continuous cast mold soft water cooling system, be included in the feed pipe and the return pipe that connect on the crystallizer, on feed pipe, connecting bypass hose, compressed air scavenging conduit and backwash return pipe respectively, on the compressed air scavenging conduit air intake control valve is housed, on the feed pipe that connects bypass hose and compressed air scavenging conduit check-valves is being set, the backwash return pipe that by-pass valve control is housed is connected on the feed pipe between compressed air scavenging conduit and the crystallizer; Outlet water control valve is being set on return pipe, the bypass hose other end is divided into backwash water inlet pipe and maintenance pipe two tubes, the backwash water inlet pipe is connected on the backwater control valve water inlet end, the maintenance pipe is connected on the backwater control valve water side, backwash water inlet pipe and maintenance are being provided with control valve respectively on the pipe, be connected crystallizer and purge drainpipe on the return pipe between backwater control valve and the crystallizer.
When the utility model uses, can carry out backsurging operation to crystallizer by the bypass hose, can also in feed pipe and crystallizer, be blown into compressed air by the compressed air scavenging conduit, crystallizer inside is purged, prevent that crystallizer inner product water from freezing phenomenon, fundamentally stopped the risk that bursting by freezing appears in crystallizer water tank and section of tubing during long-time maintenance in winter or the termination of pumping.By-pass valve control on the feed pipe closed and open by-pass valve control on the bypass hose, can be so that the soft water in the feed pipe circulate without crystallizer by the bypass hose, crystallizer can carry out online replacing under the condition of not disturbing the softened water pump operate as normal like this.In addition, after accident water enters, close the backwater control valve, can realize rapidly that the crystallizer online backflushing washes, reduce the accident treatment time, this point is particularly important at the northern area below 0 ℃ for the annual minimum temperature.The utility model is simple in structure, can satisfy the cooling requirement of crystallizer, can carry out backwash and purge operation crystallizer again, prevents the crystallizer bursting by freezing, guarantees that crystallizer normally uses.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a syndeton schematic diagram of the present utility model.
The specific embodiment
A kind of continuous cast mold soft water cooling system, as shown in drawings, be included in the feed pipe 5 and the return pipe 7 that connect on the crystallizer 6, on feed pipe 5, connecting bypass hose 1, compressed air scavenging conduit 2 and backwash return pipe 4 respectively, on the compressed air scavenging conduit 2 air intake control valve is housed, check-valves 3 is being set connecting on the feed pipe of bypass hose 1 and compressed air scavenging conduit 2, the backwash return pipe 4 that by-pass valve control is housed is connected on the feed pipe 5 between compressed air scavenging conduit 2 and the crystallizer 6; Outlet water control valve 10 is being set on return pipe 7, bypass hose 1 other end is divided into backwash water inlet pipe 11 and maintenance pipe 12 two tubes, backwash water inlet pipe 11 is connected on backwater control valve 10 water inlet ends, maintenance pipe 12 is connected on backwater control valve 10 water sides, on backwash water inlet pipe 11 and the maintenance pipe 12 control valve is being set respectively, on the return pipe 7 between backwater control valve 10 and the crystallizer 6, is being connected crystallizer purging drainpipe 8.
The utility model can be realized following three kinds of functions:
1, purges function.Air intake control valve is opened, closed check-valves 3, the compressed air in the compressed air scavenging conduit 2 can enter in the crystallizer 6 by feed pipe, and crystallizer inside is purged, and prevents crystallizer inner product water bursting by freezing pipeline.
2, backwashing function.Backwater control valve 10 and check-valves 3 are closed, and the water in the bypass hose 1 can be entered in the crystallizer 6 through return pipe 7 by backwash water inlet pipe 11, and backwash is carried out in crystallizer 6 inside, is discharged by backwash return pipe 4, thereby shortens the accident treatment time.
3, online replacing crystallizer function.Control valve on backwater control valve 10, check-valves 3 and the backwash water inlet pipe 11 is closed, water in the feed pipe 5 circulates through return pipe by bypass hose 1 and maintenance pipe 12 like this, and do not enter in the crystallizer 6, crystallizer 6 can carry out online replacing under the condition of not disturbing the softened water pump operate as normal like this.
