Description
Technical field
The invention belongs to metal plates and strips cooling processing field, particularly a kind of cooling device forming high density angular injection stream, for realizing the quick cooling to hot-finished material.
Background technology
At present, following several form is mainly contained to the device that metal plates and strips cools: one is cooling facility for laminar flow, namely use cooling water flow with certain pressure by intensive nozzle vertical impact to surface of steel plate, to realize the device cooled; Another kind is the cooling device that can form flat jet (eject slot).Cooling facility for laminar flow is lower due to cooling capacity, can not meet more and more higher process for cooling requirement; Although the device device water yield that can form flat jet is large, cooling capacity is strong, very large to face, gap processing request, and gap adjustment requires higher.
Chinese patent CN201110191861.9 discloses " can form the cooling device of high-density jet stream ", and its principle is that cooling water enters cavity volume from top to bottom, and the solid matter nozzle then through being arranged on swash plate is spouting; The inclination angle of swash plate is exactly the oblique spray angle of cooling water flow.
Chinese patent CN201110191865.7 discloses " a kind of cooling device and manufacture method forming high-density jet stream ", and its general principle is: cooling water enters cavity volume from interior pipe through aperture, and the solid matter nozzle then through being arranged on swash plate is spouting; The inclination angle of swash plate is exactly the oblique spray angle of cooling water flow.
Above-mentioned several patent has following common drawback:
1. current are opened slow---according to rolled piece run location, when PLC controls to start injection water, cooling water needs first to fill whole cavity volume, could start to spray water on roller-way, there is certain hysteresis quality, and it is not good that system opens response;
2. current are closed slow---according to rolled piece run location, when PLC controls to close injection water, although front end valve can be closed immediately, but continuation is dripped because conducting oneself with dignity by remaining cooling water lentamente from slit in (upper cooling manifold) whole cavity volume, until all flow sky, therefore can not realize cutting off the water supply instantaneously, system responses closes response extreme difference at all.
3. poor heat resistance---whole cooling device because with roller table surface close proximity, when needing not spray water according to technique, owing to there is no retaining in cavity, therefore after being subject to the heat radiation of rolled piece (hot steel plate), the temperature rise of whole device is understood larger, seal in device very easily damages, and device itself is also easy to be out of shape and accelerated deterioration because being heated for a long time.
Summary of the invention
The object of the invention is to design a kind of cooling device forming high density angular injection stream, its oblique high-density jet stream formed can produce great cooling capacity; In addition, rational in infrastructure, can spray water fast within the extremely short time and cut off the water supply fast; The water storage structure of this device can protective device self and its seal from thermal-radiating infringement, increase the service life fully.
For achieving the above object, technical scheme of the present invention is:
Form a cooling device for high density angular injection stream, it comprises, body, is rectangular box structure, comprises casing and upper cover plate, the lower shoe of upper and lower side opening; The under shed end face of casing is inclined-plane; Some through holes offered along its length by upper cover plate, and lower shoe offers some installation through holes along its length; Water inlet pipe, comprises the adpting flange of horizontally disposed straight tube, some vertical tubes that straight tube top is arranged along length of straight pipe direction and vertical tube end; Described straight tube closed at both ends, straight tube bottom arranges some apopores along its length; Each vertical tube on described straight tube is inserted in each through hole of described housing cover plate respectively; Straight tube is positioned at described body casing; Some nozzles, are arranged in the installation through hole of described body casing lower shoe respectively; Some arc drainage tubes, are arranged in described body casing, and arc drainage tube lower port connects the nozzle on lower shoe installation through hole respectively, and upper port is positioned at body casing internal upper part.
Further, the installation through-bore axis of described lower shoe and lower shoe radial direction are at angle.
Preferably, the installation through hole of described lower shoe arranges more than 2 rows in lower shoe radial direction, the setting and front and rear row installation through hole staggers.
Preferably, the straight tube bottom apopore of described water inlet pipe is provided with more than 2 along straight tube radial direction.
Cooling water is flowed in casing from water inlet pipe vertical tube equably by the multiple uniform apopore straight tube, after filling casing, flows into, eject finally by nozzle from the upper end of arc drainage tube, forms high-density jet stream.
The present invention compares aforementioned existing patent, not only achieves high-density jet stream equally, and solves the weak point of existing patent:
1. cooling water is from flowing in casing, only after filling casing, could from arc drainage tube top from up to down flow into, finally eject to nozzle.Therefore, when needs are sprayed water again, control to open front end valve, without the need to again filling whole cavity volume (casing), only need little cooling water just again can obtain high-density jet stream, the time needed for the current therefore opened is very short, and starting-up response is fast; When needs stop water spray, control closed front end valve, a small amount of cooling water at this moment only exceeding arc drainage tube top continues to flow to end from nozzle, and the time of therefore closing needed for current is also very short, cuts off response fast.
2. there is large half chests water owing to storing all the time in casing, therefore casing is in the state of cooling always, even if because technique needs temporarily not spray water, device also can not cause persistently overheating because of the heat radiation of rolled piece (hot steel plate), the solar heat protection of device is effective, device is thermal deformation not easily, and each seal life in it can extend significantly, antileaking.
3. injection stream is with certain oblique spray angle, and the cooling capacity produced when high density is sprayed is large, is applicable to carry out ultrafast cooling processing to metal plates and strips.
4. uniform apopore on water inlet pipe, cooling water, after flange enters interior pipe, fills casing by multiple apopore, ensure that the discharge uniformity of whole casing.
5. the corresponding arc drainage tube of each nozzle, for each nozzle independently supplies water, does not interfere with each other, and ensures that water flow is impartial
6. the upper end level of all (respectively arranging) arc drainage tubes flushes, and not only ensure that two row or multi-row nozzle is all fetched water from phase co-altitude; The more important thing is, through hole on its arc lower end and base plate and the injection direction of nozzle tangent, make every section of injection water all will flow through quite long one section of air line distance (being similar to the Long Barrel of rifle) before delivery nozzle, ensure that the precision of injection stream.
7. pressure tiltedly sprays, and while strike also cooling metal sheets surface, can be blown away by the water of surface of steel plate rapidly, keep in " nuclear boiling district ", reduce in " film boiling district ", cooling effect is greater than vertical injection;
