Description
Technical field
The utility model relates to belt steel surface de-scaling devices, throw water sand deoxygenation more particularly, to a kind of erect-type strip
Change leather jacket to set.
Background technique
In hot-strip cooling procedure, one layer of hard and crisp oxide layer can be generated on surface, if the oxide layer is not cleared up
Fall, roller surface will be damaged in cold rolling of strip steel production, belt steel surface is caused to generate defect, influence belt steel product after cold rolling
Quality, to guarantee that the quality of cold-strip steel finished product is met the requirements, hot-strip is had to before carrying out cold rolling by the oxidation on its surface
Skin is cleaned out, and the most common technique that descales is " pickling ", but " pickling " has the disadvantage in that acid solution corrosive equipment,
The spent acid and exhaust emission environment generated in production process, in addition, acid-washed product is easy to appear overpickling, owes pickling and hydrogen embrittlement production
Product defect is unfavorable for the cold rolling of subsequent strip.Another common descaling technique is dry type ramming, but dry type ramming exists
Following disadvantage: de-scaling rate is low, and belt steel surface easily abrades, so that belt steel surface intensity increases, can also increase the temperature of strip, cause
Deformation etc.；A large amount of dust is generated simultaneously, endangers operator's health, and dust explosion easily occurs；Dust is difficult to thoroughly divide
From being easily adhered on workpiece, influence strip surface quality.It in addition is to lay flat strip by sand slinger when this mode is cleared up,
Cleaning effect is bad, and the cleanliness of belt steel surface is lower after cleaning.
Chinese utility model patent (notification number CN204470913U) discloses a kind of erect-type belt steel surface oxide skin company
Continuous cleaning production line is overturn horizontal positioned strip for after vertical place, strip enters cleaning chamber (phase by vertical tipper
When in projectile room) belt steel surface progress water sand mixing ramming is handled by water sand injector mixer group, pass through water cleaning later
Spray head carries out water purification cleaning to treated belt steel surface, and strip goes out after cleaning chamber again by vertical tipper by vertical hot rolling
Strip overturning is horizontal positioned, while the water sand slag mixture of cleaning chamber bottom, after Pulp pump and cyclone, sand setting enters
Steel sand collecting box is recycled, and sewage enters dirty water collecting tank and carries out circulation benefit after sedimentation basin, clear water tanks, filter
With.
But the erect-type belt steel surface oxide skin in above patent document continuously clears up production line since structure is complicated, because
And high failure rate, while the motor of larger capacity is needed, energy consumption is big；On the other hand, due to the spray of composition water sand injector mixer
Nozzle may be only available for fine sand (0.1 ~ 0.2 millimeter of partial size), and fine sand can not handle thicker harder oxide skin, lead to the production
It is bad that line throws water sand treatment effect to the steel band with thicker harder oxide skin.
Summary of the invention
The utility model aim is to provide a kind of erect-type strip throwing water sand de-scaling device, solve in the prior art
Belt steel surface oxide skin continuously clears up production line, and structure is complicated, high failure rate and using fine sand to thicker harder oxide skin at
Manage ineffective problem.
To achieve the above object, the utility model can take following technical proposals:
Erect-type strip described in the utility model throws water sand de-scaling device, including with strip entrance and exit
Room is cast, is provided with the sand supplying sub-sand tank being connected to projectile room above the projectile room, is provided with opening below room casting
Towards the water sand collecting box for casting room, connect casting outdoor be respectively arranged with along two sidewalls length direction with the sand supplying sub-sand tank
Logical flinger, the flinger include protruding into the throwing for casting indoor water sand impeller head and driving water sand impeller head operation
Penetrate pump.
In order to recycle the water sand slag mixture of water sand collecting box bottom feeding sand supplying sub-sand tank, received in water sand
Header side is provided with elevator pump, and the elevator pump is connected to by pipeline with water sand collecting box, and elevator pump passes through conveying water sand
Pipe is connected to sand supplying sub-sand tank.
The sand supplying sub-sand pot bottom is provided with funnel type outlet, and the funnel type outlet is thrown by water inlet sandpipe and water sand
The connection of ball device is provided with sand valve in the junction of the water inlet sandpipe and funnel type outlet, for controlling sand supplying process.
It is utilized again after being precipitated for the mixture of fine sand and water that water sand is collected upper box part, the water sand is collected
Case side is also set up for collecting upper water sand mixture and the sedimentation and drawing slot precipitated, the sedimentation and drawing in water sand collecting box
Slot is connect with the water inlet sandpipe close to one end of water sand impeller head by water sand dilution tube.
In order to improve sedimentation effect, there are two the sedimentation and drawing slot settings.
In order to which in order to utilize again, the water sand is received after capable of mixing the water sand slag mixture of water sand collecting box bottom
The header other side is provided with the water sand mixing pump for stirring water sand collecting box bottom water sand slag mixture.
The utility model advantage is that throwing water sand using impeller head replaces high pressure liquid sandblast, improves the speed of descaling
Degree, while the motor (50% can be reduced using the general power of motor) of smaller power can be used, equipment manufacturing costs have been saved, have been dropped
The consumption of electric energy when low work；Since the device structure for throwing water constituents high pressure liquid sandblast is simple, failure rate is low, is easy maintenance,
Parts price is low, and is able to use coarse sand (0.5 ~ 0.8 millimeter of partial size) and carries out throwing thicker harder oxygen on water sand processing strip
Change skin, it is more preferable to throw water sand treatment effect to the steel band with thicker harder oxide skin.
