Abstract
The utility model discloses a self-adjusting calcining furnace spray gun cover belonging to the technical field of the cold rolling acid regeneration devices. The self-adjusting calcining furnace spray gun cover can be used to adjusting the pressure in the acid regeneration calcining furnace automatically. The self-adjusting calcining furnace spray gun cover is constituted by a fixed cover and a rotary cover. The fixed cover is in a circular shape and disposed on the top of the calcining furnace. The rotary cover is a round cover, and an external diameter of the rotary cover is cooperated with an inner diameter of the fixed cover. The rotary cover is fixedly disposed in the circular ring of the fixed cover by a rotary shaft of the rotary cover. The rotary cover and the rotary shaft of the rotary cover are in a rotatable connection, and the rotary shaft of the rotary cover is fixedly disposed on one side of the periphery of the fixed cover. In the utility model, the opening degree of the spray gun cover can be adjusted automatically according to the lever balance principle. When the negative pressure in the calcining furnace is relatively large, the rotary cover can be opened. When the negative pressure in the calcining furnace is relatively small, the rotary cover can be closed. Thereby the pressure in the calcining furnace can be adjusted. The self-adjusting calcining furnace spray gun cover provided in the utility model has advantages of simple structure, convenient use, and abilities of ensuring that the pressure in the calcining furnace is in the normal range, and reducing the corrosion and damage on the devices effectively.
Description
Technical field
Utility model relates to a kind of cold rolling acid regeneration roaster spray gun lid, belongs to cold rolling acid regeneration equipment technical field.
Background technology
In the production process of flat cold-rolled sheet, need carry out acid regeneration and handle.Under the situation that the acid regeneration equipment that uses at present is long between in use, the fluctuation of acid regeneration roaster pressure in the burner hearth is bigger, through regular meeting malleation super large or the ultralow phenomenon of negative pressure appear.During the malleation super large, the meeting etching apparatus reduces duration of service; When negative pressure was ultralow, the acid regeneration roaster was flame-out easily, and damaged the roaster anticorrosive coat.Normally carry out for what guarantee to produce, reduce, be necessary the acid regeneration roaster is improved, to eliminate the abnormal phenomenon of roaster internal pressure corrosion on Equipment and damage.
The utility model content
The utility model technical problem to be solved provides a kind of acid regeneration roaster internal pressure that can guarantee normally can self-regulating roaster spray gun lid.
The technical scheme that solves the problems of the technologies described above is:
A kind of can the lid by self-regulating roaster spray gun, it is made up of fixed cap, rotatable cover, and fixed cap is an annular; Be installed in the furnace roof of roaster, rotatable cover is a dome, and the internal diameter of its external diameter and fixed cap is complementary; Rotatable cover is positioned at the annulus of fixed cap; Be fixed in the fixed cap by the rotatable cover rotating shaft, rotatable cover and rotatable cover rotating shaft are for being rotatably connected, and the rotatable cover rotating shaft is positioned at a side of fixed cap circumference.
Above-mentioned can the lid by self-regulating roaster spray gun has balancing weight on rotatable cover, balancing weight is positioned at less semicircle one side of being cut apart by the rotatable cover rotating shaft of rotatable cover.
Above-mentioned can be self-regulating roaster spray gun lid, steady pin is installed on the described fixed cap annulus, steady pin and rotatable cover are flexible connection.
The utility model utilizes lever balance theory, regulates the opening degree of spray gun lid automatically, and when roaster negative pressure occurs when big, rotatable cover is opened, and when roaster negative pressure occurs when less, rotatable cover is closed, and regulates the pressure in the roaster with this.The utility model is simple in structure, easy to use, can guarantee that the pressure in the roaster is in normal range (NR), reduces effectively corrosion on Equipment and damage.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the user mode sketch map of the utility model;
Fig. 3 is the another kind of user mode sketch map of the utility model.
Mark is following among the figure: fixed cap 1, rotatable cover 2, rotatable cover rotating shaft 3, balancing weight 4, steady pin 5, roaster 6.
The specific embodiment
Show among the figure that the utility model is made up of fixed cap 1, rotatable cover 2.
Show among the figure that fixed cap 1 is an annular, is installed in the furnace roof of roaster.
Show among the figure that rotatable cover 2 is a dome, its external diameter is identical with the internal diameter of fixed cap 1, and rotatable cover 2 is fixed in the annulus of fixed cap 1 by rotatable cover rotating shaft 3.Rotatable cover rotating shaft 3 horizontal positioned are passed rotatable cover 2 along the plane of rotatable cover 2, and it is inboard that the two ends of rotatable cover rotating shaft 3 are inserted into fixed cap 1 annulus, and rotatable cover 2 can rotate around rotatable cover rotating shaft 3.
Show among the figure that the position of rotatable cover rotating shaft 3 is not on the diameter of rotatable cover 2, and is and parallel with diameter, be positioned at a side of rotatable cover 2 circumference, rotatable cover 2 is divided into two parts that area differs in size.Balancing weight 4 is arranged on rotatable cover 2, and balancing weight 4 is positioned at less semicircle one side of the rotatable cover cut apart by rotatable cover rotating shaft 32.The effect of balancing weight 4 is just often to make rotatable cover 2 be in poised state in roaster 6 internal pressures.
Show among the figure; Steady pin 5 is installed on fixed cap 1, and steady pin 5 is positioned at bigger semicircle one side of the rotatable cover cut apart by rotatable cover rotating shaft 32, and an end of steady pin 5 is fixed on the annulus of fixed cap 1 on the plane; The other end stretches out the annulus of fixed cap 1, and retaining is above rotatable cover 2.
The utility model course of work is:
When roaster 6 negative pressure occurs when big, rotatable cover 2 attractions are strengthened, rotatable cover 2 is opened downwards.When malleation appearred in roaster 6, rotatable cover 2 was blown afloat by steam in the stove, and rotatable cover 2 is upwards closed.
