Abstract

The utility model relates to the mechanical equipment, in particular to a gas knife fitting for the continuously hot-dipped plating line of the strip steel. The fitting is equipped with a main beam. A nozzle suspended underneath the main beam through a hanging frame is arranged over a zinc pot. The gas supply pipeline supplies the gas to two ends of the nozzle through the main beam and the cavity of the hanging frame. The main beam is supported on a base by a shift mechanism and an elevator. A mechanism for adjustment of the nozzle angle is arranged on the main beam. The utility model is characterized in that the nozzle has a hollow cylinder body on which two cheek plates are welded, a hole plate is connected between the two cheer plates. Thus the cheer plate forms a cuniform shape. An upper lip piece, a lower lip piece and a lip piece shield are respectively arranged on the two cheer plates and are fixed by the adjustment bar and screw. The benefit effects of the utility model are: easy manufacturing, convenient maintenance, cheap and perfect product, and is applicable to the present condition of our nation.

Description

The airblade device that band steel continuous hot-dipping line is used
(1) technical field: the utility model relates to mechanical means, is a kind of be used to control belt steel surface thickness of coating, inhomogeneity device, is specifically related to a kind of airblade device of using with the steel continuous hot galvanizing line.
(2) background technology: the present used airblade device of countries in the world band steel continuous hot-dipping, common point is arranged, promptly form by airing system, air knife body and lifting and translocating mechanism, the air knife body all has nozzle usually, nozzle opening can be regulated, to adapt to different coating weights; The air knife that has adopts the multiple spot air inlet, enters nozzle by the gas collection cylindrical shell, but complex structure, effect is not good enough; The lip sheet of nozzle has run-in index, curvilinear style also to have segmentation adjustable, and nozzle air blowing direction and band steel angle should be adjustable, but the adjustment mechanism complexity haves much room for improvement; Lifting and translocating mechanism is used for regulating the horizontal and vertical position of air knife, suitable suitably simplification; The air feed of air knife is all used multistage centrifugal blower usually, has the problem of the huge power consumption waste of gas blower.
(3) summary of the invention: at the problems referred to above, the utility model provides a kind of airblade device of using with steel continuous hot-dipping line, and it is easy to make, is convenient to safeguard, good and cheap, is fit to China's actual conditions.
Technical scheme is: the airblade device that band steel continuous hot-dipping line is used is provided with girder, nozzle is suspended under the girder by suspension bracket, be positioned at zinc pot top, the inner chamber of supply air line by girder and suspension bracket is to the nozzle ends air feed, girder can be adjusted air knife nozzle and the distance of being with steel by shift mechanism, hoisting appliance is supported on the base, also be provided with the nozzle angle adjustment mechanism on the girder, it is characterized in that: the cylindrical shell of nozzle tool hollow, be welded with two cheeks on the cylindrical shell, orifice plate is connected between two cheeks, and cheek constitutes wedge shape, be respectively arranged with upper labial plate on two cheeks, labial plate and lip sheet cover plate, and by adjusting usefulness bar and screw retention on cheek; Shift mechanism by the horizontal slideway that connects girder, with travel mechanism in screw mandrel and the swing handle of handling screw mandrel constitute; Hoisting appliance is made up of tail rod, motor hoist (containing motor, shaft coupling, worm and gear elevator), and the girder end is nested with on tail rod, and motor hoist drives the girder lifting by the rotation of worm and gear elevator; The nozzle angle adjustment mechanism is fixed on the end of nozzle by the crank slot handle of manual worm, worm gear, linkage assembly; Air pressure system is provided by the speed control by frequency variation multistage centrifugal blower in the steam line.
The beneficial effects of the utility model are: be easy to make, be convenient to maintenance, good and cheap, be fit to national conditions.
(4) description of drawings:
Fig. 1 is the sectional structure synoptic diagram of nozzle, vertically analyses and observe along the nozzle on Fig. 2;
Fig. 2 is a structural representation of the present utility model.
Among the figure: the 1-cylindrical shell, the 2-cheek, the 3-orifice plate, the 4-upper labial plate, 5-labial plate, 6-are adjusted and are used bar, 7-lip sheet cover plate, 8-nozzle, 9-girder, 10-suspension bracket, 11-nozzle angle adjustment mechanism, the 12-shift mechanism, 13-hoisting appliance, 14-base, 15-supply air line, 16-zinc pot.
(5) embodiment:
Referring to Fig. 1, Fig. 2, each component of the utility model, except that general parts such as worm gear, worm screw, gas blower, electric motor, bolt, nut are market is bought, each component all is that steel are made by oneself through mechanical workout, even for guaranteeing the belt steel surface zinc coating, thickness also closes requirement, must do following the adjustment before the utility model uses: the two lip spacings of adjusting nozzle 8, scope is 0.2-3.5mm, and this determines thickness of coating; Adjust nozzle angle, finish, can in-6 °~+ 30 ° scopes, adjust with nozzle angle adjustment mechanism [11]; Move horizontally girder [9] with shift mechanism [12], make the requirement that conforms with the regulations of nozzle and band steel spacing; Move girder [9] with hoisting appliance, make the requirement that conforms with the regulations of nozzle and snail interplanar distance; Regulate air pressure air flow with the speed control by frequency variation multistage centrifugal blower.Carry out after the above various adjustment, the air knife that blast comes out to form from nozzle just can make the zinc bed thickness evenly thin, and thickness conforms with specification of quality.
