Description
Technical field
The present invention relates to exsiccator, it is a kind of continuous casting covering slag fluidization drying device.
Background technology
The continuous casting covering slag drying meanss that ladle uses are typically the heating of pot method, with the knot of air mixture cartridge heater and steel plate
Fruit is heated, or utilizes tundish waste heat radiation heating baking.The deficiency of both approaches is that heating process is uncontrollable, only
Temperature can be grasped with the experience of operator, because heat cannot be dispersed, lead to a part of covering slag that burning, decarburization occur
Or the phenomenon such as conglomeration, then water content is big for another part covering slag, causes steel billet to produce bubble or crackle, has a strong impact on product matter
, often waste product, makes production cost higher, and affect product quality in amount.
Content of the invention
It is an object of the invention to provide a kind of continuous casting covering slag fluidization drying device, to solve the deficiencies in the prior art.
The present invention for achieving the above object, by the following technical programs：A kind of continuous casting covering slag fluidization drying device, including
Tundish, the exit of tundish is communicated with air inlet pipe one end, and the air inlet pipe other end is communicated with high-pressure vortex blower fan, high-pressure vortex
The outlet of blower fan is communicated with escape pipe one end, and escape pipe is installed regulating valve, and the other end of escape pipe is connected with fluid bed air chamber,
And communicate with fluid bed air chamber inner chamber, setting point filter device in fluid bed air chamber, point filter device top is covered with protection solid impurity particle.
For realizing the purpose of the present invention further, can also employ the following technical solutions：Described point of filter device is by upper filter screen
Form with lower filter screen, upper filter screen and lower filter screen are rectangle, uniform through hole on upper filter screen, the middle part of lower filter screen opens up center and leads to
Hole, the corner location of lower filter screen opens up first through hole, the second through hole, third through-hole and fourth hole, other of lower filter screen respectively
Position uniformly opens up several micropores.First through hole centrage and the setting first of the second through hole centreline space are apart from L1, the second through hole
Centrage arranges second distance L with third through-hole centreline space2, first through hole centrage and central through hole centreline space setting the
Three apart from L3, first apart from L1, second distance L2With the 3rd apart from L3Identical length etc..The diameter D of central through hole1More than second
The diameter D of through hole2, the diameter of the second through hole is equal with the diameter of the diameter of first through hole, the diameter of third through-hole and fourth hole
Equal.
It is an advantage of the current invention that：Using high-pressure vortex blower fan collect tundish waste heat, high-pressure delivery to fluid bed air chamber,
Hot-air fluidizes uniform heated protective solid impurity particle through a point filter device again, so that protection solid impurity particle thermally equivalent is dehydrated, protects solid impurity particle
Occurring without the deficiencies such as conglomeration, burning, decarburization, moisture be big, making strand not produce the phenomenons such as bubble or crackle, thus significantly carrying
High billet quality.
Brief description
Accompanying drawing 1 is the structural representation of the present invention；Accompanying drawing 2 be in Fig. 1 A to structural representation；Fig. 3 be in Fig. 1 B to structure
Schematic diagram.
Specific embodiment
The present invention will be further described for comparison accompanying drawing.
In figure 1 is tundish, and the exit of tundish 1 is communicated with air inlet pipe 7 one end, air inlet pipe 7 other end and high pressure whirlpool
Flow fan 2 communicates, and the outlet of high-pressure vortex blower fan 2 is communicated with escape pipe 8 one end, and escape pipe 8 is installed regulating valve 3, escape pipe 2
The other end be connected with fluid bed air chamber 6, and communicate with fluid bed air chamber 6 inner chamber, a setting point filter device in fluid bed air chamber 6,
Filter device top is divided to be covered with protection solid impurity particle 4.The waste heat of tundish 1 is introduced fluid bed by high-pressure vortex blower fan 2 by the present invention
In air chamber 6, make that the residual heat air current from tundish 1 is full and uniform in the presence of point filter device to be distributed in fluid bed air chamber 6
Interior, protection solid impurity particle 4 is toasted, realizing uniformly being dehydrated, making not burning in dehydration, also not backwater, thus improving casting
Base quality.
The present invention provide further scheme be：Described point of filter device is made up of upper filter screen 5 and lower filter screen 9, upper filter screen 5 He
Lower filter screen 9 is rectangle, uniform through hole 10 on upper filter screen 5, and the middle part of lower filter screen 9 opens up central through hole 11, the corner of lower filter screen 9
Position opens up first through hole 12, the second through hole 13, third through-hole 14 and fourth hole 15 respectively, and other positions of lower filter screen 9 are equal
Even open up several micropores.This is the special construction making thermal current uniformly spread and arranging in order to realize the uniform baking to covering slag,
It can be further ensured that protection solid impurity particle occurs without clustering phenomena.
Present invention scheme preferential further is：First through hole 12 centrage and the second through hole 13 centreline space setting first
Apart from L1, the second through hole 13 centrage and third through-hole 14 centreline space arrange second distance L2, first through hole 12 centrage with
The setting the 3rd of heart through hole 11 centreline space is apart from L3, first apart from L1, second distance L2With the 3rd apart from L3Identical length etc..
The diameter D of central through hole 111Diameter D more than the second through hole 132, the diameter of the second through hole 13 and the diameter of first through hole 12, the
The diameter of the diameter of three through holes 14 and fourth hole 15 is all equal.This center leads to steam and surrounding and leads to steam and connects air-flow
Structure, makes the waste heat of tundish 1 produce hairspring class air-flow in fluid bed air chamber 6, uniform, trickle to protection solid impurity particle baking,
Protection solid impurity particle is made slowly to be subject to heat abstraction moisture, it is to avoid the deficiency such as burning, decarburization, conglomeration.
The non-detailed description of the present invention is known technology.
