Abstract
The utility model belongs to the improvement that caster two cold arranges vapour system structure, particularly a kind of improved continuous casting secondary cooling zone row steam blower fan, it is included in the blast pipe connected on the air inlet of blower fan, settling tank is connected in the outlet of the horizontal air intake bottom of the tube of blower fan, drainpipe is set on the tank wall of precipitation upper box part, manhole is set on the side wall of settling tank, sealing maintenance door is installed with by bolt on manhole.The utility model is rational in infrastructure, can solve the ponding in fan casing, when checking sediment case, attendant station easily can clean out the bits of the inside on the ground, scarfing cinder operation in fan casing need not entered, the amount of labour of workman is being greatly decreased, eliminated safe hidden trouble.
Description
Technical field
The utility model belongs to the improvement that caster two cold arranges vapour system structure, and particularly a kind of improved continuous casting is secondary
Arrange steam blower fan in cooling zone.
Background technology
Caster two cold row's vapour system is main by equipment such as row's jet chimney, manual modulation valve, row's steam blower fan units
Composition.
The steam that molten steel is produced in two cold houses is mainly extracted out and is discharged into outdoor by continuous casting two cold blower fan, makes crystallizer week
Enclose gap and be in negative pressure or slight positive pressure state, to avoid overflowing the sight line of the excessive influence operating personnel of quantity of steam.
The water smoke that nozzle is ejected in process of production is inhaled into two cold smoke evacuation systems together with the steam in two cold houses
In system；In the two cold smoke evacuation systems that the debris such as the covering slag for being spilt in conticaster casting process and small cold steel are drawn into simultaneously.
In certain hour, a large amount of accumulated slags in fan casing bottom and certain ponding are caused, and block blower fan drainpipe.Last substantial amounts of steam
Arranged in air by two cold chimneys, freezed in winter is very serious around chimney, there is larger potential safety hazard.
Blower fan inspection hole must be removed within every 2 months, attendant enters into the product of cleaning bottom of shell in fan casing
Slag and dirt, and clear up the drainpipe of fan casing bottom.As cleaning not in time can fan impeller cause certain infringement, and
And there is larger potential safety hazard into working in fan casing in attendant.
Utility model content
The purpose of this utility model is to provide a kind of improved continuous casting secondary cooling zone row steam blower fan, and its structure is closed
Reason, can solve the ponding in fan casing, and when checking sediment case, attendant station on the ground can easily by the inside
Bits are cleaned out, it is not necessary to entering scarfing cinder operation in fan casing, the amount of labour of workman is greatly decreased, eliminating safety hidden
Suffer from.
What the purpose of this utility model was realized in：A kind of improved continuous casting secondary cooling zone row steam blower fan, including
The blast pipe connected on the air inlet of blower fan, settling tank is connected in the outlet of the horizontal air intake bottom of the tube of blower fan, heavy
Drainpipe is set on the tank wall of shallow lake upper box part, manhole is set on the side wall of settling tank, bolt is passed through on manhole
Sealing maintenance door is installed.
Principle of the present utility model is in horizontal fan blast pipe（φ1500mm）Bottom, with steel plate made one it is long
1.1 meters, wide 1 meter, 0.8 meter high of rectangle sediment case, and install drainpipe additional in about 2/3 position of sediment case height.
Using effect：
After installing sediment case additional, original is deposited in the bits of the fan casing bottom overwhelming majority and is all deposited in sediment case, airduct
Condensed water also mainly carries out draining by the drainpipe above sediment case, and the ponding in fan casing is resolved.Periodically will
The manhole of sediment case is opened, and attendant station easily can clean out the bits of the inside on the ground, it is not necessary to
Scarfing cinder operation in into fan casing, is greatly reduced the amount of labour of worker, also eliminates potential safety hazard.
The utility model is rational in infrastructure, solves the ponding in fan casing, and when checking sediment case, attendant stands on ground
Easily the bits of the inside can be cleaned out on face, it is not necessary to entering scarfing cinder operation in fan casing, be greatly reduced
The amount of labour of workman, eliminates potential safety hazard.
Brief description of the drawings
The utility model is further described below in conjunction with accompanying drawing, Fig. 1 illustrates for the utility model front view structure
Figure.
Specific embodiment
A kind of improved continuous casting secondary cooling zone row steam blower fan, as shown in figure 1, be included on the air inlet of blower fan 1 connecting
The blast pipe 2 for connecing, is connected to settling tank 3, in the tank wall on the top of settling tank 3 in the outlet of the bottom of horizontal blast pipe 2 of blower fan 1
On drainpipe 4 is set, manhole is set on the side wall of settling tank 3, on manhole by bolt be installed with sealing inspection
Repair door.The condensed water discharge pipe 5 being connected with the bottom of shell of blower fan 1 in the drainpipe 4 of the connection of settling tank 3 is connected.In settling tank 3
Bottom supporting leg 6 is set.
