Detailed description of the invention
Embodiment 1
In conjunction with Fig. 1, a kind of acid tank cover of the descaling bath of the present embodiment, including enclosing cover and inner cap, this enclosing cover and inner cap share a curved roof 2, the left and right sides of this curved roof 2 is symmetrical, curved roof 2 in the present embodiment is provided with explosionproof hole, being disposed to of this explosionproof hole: avoid the hydrogen that chemistry reflection displaces to assemble in descaling bath and too much cause security incident, improve production security, curved roof 2 in the present embodiment is symmetrically set with two hangers 5, this hanger 5 the opening and closing facilitating acid tank cover are set.
As it is shown in figure 1, enclosing cover also includes enclosing cover side plate 1, the surrounding of curved roof 2 is all welded with the enclosing cover side plate 1 of vertically placement, and wherein, the enclosing cover side plate 1 that enclosing cover side plate 1 that front and back set up, right and left set up is corresponding parallel respectively; The left and right sides of the enclosing cover side plate 1 in the present embodiment is provided with enclosing cover edge 7, and this enclosing cover edge 7 can be used for improving the sealing of descaling bath; On enclosing cover edge 7 in the present embodiment, equally spaced being provided with strengthens plate 4.
As shown in Figure 1, inner cap also includes deflector 3, and this deflector 3 is arranged on the surrounding inside curved roof 2, and the quantity of deflector 3 is four and this deflector 3 and the angle of vertical direction is ��, angle �� in the present embodiment be sized to 15 ��, the opening of inner cap is along the vertical direction in tapered condition. Covering in the present embodiment and be provided with reinforcement 6, the two ends of this reinforcement 6 are connected with front and back deflector 3, and the setting of this reinforcement 6 can meet the intensity of inner cap.
Specifically in the present embodiment, during pickling, the acid solution in acid tank cover can form acid mist because of temperature impact, and acid mist gathers and again liquefies below curved roof 2, and the medial surface along curved roof 2 flows back in descaling bath, curved roof 2 is arcuate structure, is more beneficial for the backflow of acid solution, but technical staff finds in long-term production process, the part acid solution of post liquefaction finally can be back in water sealed tank along curved roof 2, gradually by the clear water acidifying in water sealed tank, not only pollutes water quality, also result in the wasting of resources of acid solution, improve production cost, for avoiding this phenomenon, technical staff creatively with the addition of the design of deflector 3, this deflector 3 is arranged on the inner side of enclosing cover, and deflector 3 tilts to curved roof 2 centre, when acid tank cover is covered above descaling bath, enclosing cover is positioned at water sealed tank, and deflector 3 contacts with the inner side of the pickling tube sidewall in descaling bath just, by intercepting completely between pickling tube sidewall and water sealed tank, acid mist liquefaction tailing edge curved roof 2 when refluxing, water sealed tank can be cannot be introduced into because of the stop of deflector 3, thus the surface along deflector 3 all flows back in descaling bath, avoid the acid solution wasting of resources. angle between this deflector 3 and vertical direction is ��, the effect tool that the size of �� refluxes for acid solution has a certain impact, if �� is excessive, can cause that in acid solution backflow, speed is excessively slow by resistance is excessive, if �� is too small, then it is unfavorable for coordinating of whole acid tank cover and descaling bath, technical staff gropes through constantly experiment, finally found that when �� is 15 ~ 30 �� most useful for production and application, neither affects the back-flow velocity of acid solution, is also beneficial to coordinating of whole acid tank cover and descaling bath, and specifically �� is 15 �� in the present embodiment.
In order to strengthen the structural strength of acid tank cover, interior covering is provided with reinforcement 6, the two ends of this reinforcement 6 are connected with front and back deflector 3, curved roof 2 offers the explosionproof hole running through its thickness, steel band is in acid cleaning process, it is likely to displace a small amount of hydrogen because chemistry reflection occurs, hydrogen is assembled in descaling bath and is too much then easily caused security incident, in order to improve production security, technical staff has offered explosionproof hole on curved roof 2, this explosionproof hole is smaller, it is possible to is discharged by the hydrogen produced at any time, is not result in again leaking in a large number of acid mist.
Embodiment 2
With embodiment 1, institute the difference is that in the present embodiment �� be sized to 20 ��.
Embodiment 3
With embodiment 1, institute the difference is that in the present embodiment �� be sized to 30 ��.
Schematically the present invention and embodiment thereof being described above, this description does not have restricted, and shown in accompanying drawing is also one of embodiments of the present invention, and actual structure is not limited thereto. So, if those of ordinary skill in the art is enlightened by it, when without departing from the invention objective, design the frame mode similar to this technical scheme and embodiment without creationary, protection scope of the present invention all should be belonged to.
