Abstract
The utility model provides a kind of height-adjustable nozzle; mainly comprise nozzle, water inlet pipe, also comprise transmission mechanism; described transmission mechanism is the tooth bar being arranged on leg surface and the gear cooperatively interacted with tooth bar; described gear is built in casing; tooth bar on column and surface thereof connects protective cover through casing; the side of nozzle water inlet is fixedly connected with uprights vertical, and described water inlet pipe is two, arranges lock-screw and fix column outside casing.Water shape according to ejection regulates nozzle to the distance of cooling metal sheets, thus improves the cooling uniformity of steel plate, improves the cooling capacity of system simultaneously.
Description
Technical field
The utility model belongs to field of metallurgical equipment, particularly relates to for rolling mill for hot rolled planks and strips roller repairing device nozzle.
Background technology
Controlled cooling model be by the cooling velocity after controlling hot rolled steel plate and rolling to reach the object improving its structure and properties, common are spray, aerosol, laminar flow, water curtain and the ultrafast type of cooling such as cold.The mounting means that existing hot rolled strip roller repairing nozzle adopts usually is that nozzle and pressing plate weld together, then is fixed by bolts on protective cover, and this nozzle distance cooling roller bed height immobilizes.A problem is there is in this mounting means when using, because hot rolled steel plate roller repairing technique is different, institute's water consumption is not identical yet, if when the flow of water is little, the current ejected from nozzle there will be bifurcated, spray is fallen and is treated, on cold upper surface of steel plate, to cause steel plate inhomogeneous cooling.
" a kind of lengthening type atomized spraying nozzle " (99217245.4) disclose relevant nozzle, the cylindrical surface portion at Conic nozzle rear portion is set in the end of nozzle body endoporus, and form annular between nozzle body endoporus and let out air port, shower nozzle taper seat is evenly equipped with near letting out air port the apopore communicated with the axial water hole in it, plinth offers endoporus, the air inlet communicated with endoporus, water inlet, lengthen airduct and connect nozzle body and plinth, aqueduct is installed on the nozzle body connected as one, lengthen the axial location in airduct and plinth, one end is connected with the axial water hole in shower nozzle, the other end communicates with the water inlet be arranged on plinth through flow control valve.This nozzle can be directly injected to aerosol the thermal treatment zone of inner surface of pipe fitting, and its weak point is, nozzle can not adjust height according to the water shape of the thickness of cooling metal sheets or nozzle ejection.
" a kind of aerosol nozzle for cooling of intermediate slab " (200920128125.7) the utility model discloses a kind of aerosol nozzle for cooling of intermediate slab that can prevent blocking, and are applicable to the Spray Cooling System such as various steel plate, intermediate blank.The utility model comprises nozzle body, be arranged on gas channels in nozzle body and waterway channel, with the friction tight gas circuit of import leading portion, the water route impurities device of gas circuit, waterway channel, with nozzle body inner chamber tight fit mixture and the fog-spray nozzle that is fixed on nozzle body; The utility model, by arranging gas circuit, the water route impurities device of band multilayer hole filter screen in nozzle, improves stability and the product quality of system cloud gray model, decreases the time of maintenance, extend the service life of nozzle.Its weak point is: nozzle can not adjust height according to the water shape of the thickness of cooling metal sheets or nozzle ejection.
Utility model content
The purpose of this utility model is to overcome the problems referred to above and not enough and provide a kind of height-adjustable nozzle, improves the cooling uniformity of steel plate, improves the cooling capacity of system simultaneously.
A kind of height-adjustable nozzle; comprise nozzle, water inlet pipe; also comprise transmission mechanism; described transmission mechanism is the tooth bar being arranged on leg surface and the gear cooperatively interacted with tooth bar; described gear is built in casing, and the tooth bar on column and surface thereof connects protective cover through casing, and the side of nozzle water inlet is fixedly connected with uprights vertical; described water inlet pipe is two, arranges lock-screw and fix column outside casing.
Described casing is divided into upper box and lower box, arranges axle in casing, and axle passes and is fixed on gear core, and axle both sides are arranged between upper box and lower box by bearing.
Described casing is bolted on protective cover, is fixed on protective cover by lower box by bolt.
The beneficial effects of the utility model are: the water shape according to ejection regulates nozzle to the distance (i.e. position height) of cooling metal sheets, thus improves the cooling uniformity of steel plate, improves the cooling capacity of system simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model scheme of installation.
In figure, 2 is nozzle, and 4 is protective cover, and 5 is bolt, and 8 is lower box, and 9 is lock-screw, and 10 is water inlet pipe, and 11 is column, and 12 is protective cover, and 13 is tooth bar, and 14 is water inlet pipe, and 15 is hold-down screw, and 16 is upper box, and 17 is gear, and 19 is axle, and 20 is bearing.
Detailed description of the invention
As Fig. 1, shown in 2, a kind of height-adjustable nozzle, comprise nozzle 2, water inlet pipe, also comprise transmission mechanism, described transmission mechanism is the tooth bar 13 being arranged on column 11 surface and the gear 17 cooperatively interacted with tooth bar 13, described gear 17 is built in casing, tooth bar 13 on column 11 and surface thereof connects protective cover 12 through casing, the side that nozzle 2 is intake is fixedly connected with column 11 is vertical, described water inlet pipe is two, be respectively water inlet pipe 10, water inlet pipe 14, water inlet pipe 10 is water pipe, the guide bar moved up and down of water inlet pipe 14, lock-screw 9 is set outside casing and fixes column 11.
Described casing is divided into upper box 16 and lower box 8, arranges axle 19 in casing, and axle 19 passes and is fixed on gear 17 core, and axle 19 both sides are arranged between upper box 16 and lower box 8 by bearing 20.
Described casing is fixed on protective cover 4 by bolt 5, is fixed on protective cover 4 by lower box 8 by bolt 5.
As shown in Figure 1, 2, in application process, according to the water shape that nozzle 2 sprays, turning cylinder 19, driven gear 17 rotates, the motion of pinion rack 13, tooth bar 13 is fixed on column 11 by hold-down screw 15, and column 11 is fixed together with nozzle 2 again, and therefore nozzle 2 moves up and down with tooth bar 13, when nozzle 2 moves to a desired location, then fix nozzle 2 with lock-screw 9.Nozzle 2 can move up and down according to actual service condition, and protective cover 12 covers column 11, gear 15 from above, prevent from entering foreign matter.
