Description
Technical field
The utility model belongs to steel rolling equipment technical field, is related to dephosphorization apparatus, specifically a kind of broad-adjustable
Water-saving section acid dephosphorization apparatus.
Background technique
Steel is oxidized at high operating temperatures, is formed on its surface one layer of fine and close iron scale (phosphorus skin).Before the rolling
If cannot remove this layer of iron scale, they can be pressed into belt steel surface by roll during the rolling process, influence its surface
Quality.Remaining iron scale can also accelerate the abrasion of roll, reduce the service life of roll, it is therefore desirable to carry out before the rolling
Dephosphorization.Common dephosphorization mode has pickling dephosphorization and high pressure water dephosphorization, and simple pickling is larger except phosphoric acid consumes, and high pressure water dephosphorization
Equipment is to determine for the plate of maximum width, however because of the market demand, steel plate width size when nozzle quantity designs
And disunity, and injector spacing is smaller and work is in the big adverse circumstances of high temperature, steam, is unfavorable for pacifying on each nozzle
Opening valve is filled to adjust the dephosphorization width of control-cooling equipment, when the narrower width of steel plate, the nozzle more than steel plate width is just risen not
To the effect of dephosphorization, the waste of water and the kinetic energy waste of high pressure water system are formd, operating cost is increased.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of broad-adjustable water-saving section acid dephosphorization apparatus, energy
The plate for enough adapting to different in width reduces water waste and reduces sour consumption, realizes good phosphor-removing effect.
The technical solution adopted in the utility model is:
A kind of broad-adjustable water-saving section acid dephosphorization apparatus, including high pressure water dephosphorization unit, high pressure water dephosphorization unit include
High-pressure feed water pipe with water inlet, the fixed nozzle group for being set to high-pressure feed water pipe output end, it is critical that the dephosphorization apparatus
It further include being set to descaling bath in front of high-pressure feed water pipe along the conveying direction of plate, the high-pressure feed water pipe output end is solid
To determine nozzle sets two sides and is provided with adjustable water spray group, the adjustable water spray group includes one group of adjustable nozzle of supporting block and its inside,
Supporting block side is provided with the jack communicated with all adjustable nozzles, and high-pressure feed water pipe two sides are fixed with telescopic device, stretch
The telescopic end of compression apparatus be connected with the inserted link being slidably matched with jack, inserted link and jack formed by the stretching of telescopic device it is adjustable
The folding control unit of nozzle.
The telescopic device is electric pushrod, which is also equipped with controller, the signal output end of controller
It is connected with the control terminal of electric pushrod.
Gasket is provided between the inserted link and supporting block.
The adjustable nozzle is arranged at equal intervals.
Be provided with elevator pump in the descaling bath, the inlet of elevator pump and the tail end of descaling bath connect, liquid outlet with
The head end of descaling bath connects.
The beneficial effects of the utility model are: being additionally arranged descaling bath in front of high-pressure feed water pipe, make pickling dephosphorization and high pressure water
Dephosphorization combines, and keeps dephosphorization more thorough.Plate first passes around descaling bath, the oxidation of pickling solution and plate surface in descaling bath
Layer reacts；Plate after pickling passes through high-pressure feed water pipe, and high-pressure feed water pipe is by fixed nozzle group, adjustable nozzle group to plate
Material sprays high pressure water, and since the oxidated layer thickness after overpickling reduces, oxide layer is relaxed, there is no need to hypertonia
Oxide layer can be cut, be washed away by high pressure water, and due to the presence of later period high-pressure feed water pipe, the concentration of pickling solution was not necessarily to
Height reduces the dosage of pickling solution, reduces processing difficulty and economic attrition；The setting width of fixed nozzle group on high-pressure feed water pipe
Suitable for the width of most narrow boards material, adjustable spray module is set in fixed nozzle group two sides, by telescopic device to adjustable water spray
The water spray width of component is adjusted, and so that its working range is suitable for the width of the plate of wanted dephosphorization, is realized dephosphorization width
It is adapted with strip width, does not influence phosphor-removing effect and reduce water consumption, reduce operating cost, there is good economic effect
Benefit.

Specific embodiment
A kind of broad-adjustable water-saving section acid dephosphorization apparatus, including high pressure water dephosphorization unit, high pressure water dephosphorization unit include
High-pressure feed water pipe 1 with water inlet 2, the fixed nozzle group 3 for being set to 1 output end of high-pressure feed water pipe, it is important to, dephosphorization dress
Setting further includes the descaling bath 9 that 1 front of high-pressure feed water pipe is set to along the conveying direction of plate 0, and the high-pressure feed water pipe 1 exports
End is provided with adjustable water spray group in 3 two sides of fixed nozzle group, and the adjustable water spray group includes supporting block 4 and its internal one group can
Nozzle 5 is adjusted, 4 side of supporting block is provided with the jack communicated with all adjustable nozzles 5, and 1 two sides of high-pressure feed water pipe are fixed with
Telescopic device 6, the telescopic end of telescopic device 6 are connected with the inserted link 7 being slidably matched with jack, and inserted link 7 and jack are by flexible dress
The stretching for setting 6 forms the folding control unit of adjustable nozzle 5.
Embodiment 1, as shown in Figure 1, elevator pump is provided in descaling bath 9, the inlet of elevator pump and the tail end of descaling bath
The head end of connection, liquid outlet and descaling bath connects.When work, elevator pump is opened, elevator pump is defeated by the pickling solution of 9 tail end of descaling bath
It send to the head end of descaling bath 9, increases the turbulence level of pickling solution in descaling bath 9, to increase pickling solution and the contact of plate 0 and expansion
Speed is dissipated, pickling effect is effectively improved.Plate 0 after overpickling enters high pressure water dephosphorization unit, in high pressure water dephosphorization unit
High-pressure feed water pipe 1 is separately positioned on the two sides up and down of 0 transfer passage of plate, and fixed nozzle group 3 is true according to most narrow 0 size of plate
Fixed, the setting of the fixed nozzle group 3 of upper and lower two sides is identical, and supporting block 4 and the welding of high-pressure feed water pipe 1 are connected, adjustable nozzle group
