A kind of anti-wave board structure being applicable to Mobile low-temperature wet tank equipment, its technical scheme is such: it comprises main washboard, the profile of described main washboard is Conical Shells With hollow structure, it is characterized in that: the closing in section of described main washboard has been welded to connect overlap joint cylinder, the center shaft of described overlap joint cylinder coincides with the center shaft of wet tank, the flared end of described main washboard has been welded to connect folded structure, the flared end of described main washboard, the corresponding part that folded structure forms is welded with reinforcing pad, the outer ring surface of reinforcing pad is welded to connect the tube structure of storage tank equipment, the conical surface of described main washboard is furnished with some liquid macropores excessively.

It is further characterized in that:

The inclined-plane that described folded structure is corresponding had liquid aperture, crosses liquid aperture and be radially uniformly distributed;

The inner of described overlap joint cylinder is provided with the flanging section of turning up, and described flanging section is positioned at the inner side of the closing in section of described main washboard, and the closing in section of described main washboard is welded to connect described flanging section.

After adopting structure of the present utility model, main washboard is 360 ° of pyramidal structures, main washboard is opened some groups cross liquid macropore and cross pore, circular hole is arranged and is uniformly distributed along radius, middle overlap joint cylinder center is consistent with tank body direction, main washboard again with flap and reinforcing pad structure welding, main washboard is by locally overlapping the intensity that cylinder, flap and reinforcing pad strengthen washboard, both improve the anti-of washboard and swung effect, again reduce the manufacture difficulty in production process and cost.

Accompanying drawing explanation

Fig. 1 is front view structural representation of the present utility model;

Fig. 2 is birds-eye view structural representation of the present utility model;

Reference name in figure corresponding to each sequence number is as follows:

Main washboard 1, closing in section 2, overlap joint cylinder 3, flared end 4, folded structure 5, reinforcing pad 6, excessively liquid macropore 7, excessively liquid aperture 8, flanging section 9.

Detailed description of the invention

A kind of anti-wave board structure being applicable to Mobile low-temperature wet tank equipment, see Fig. 1, Fig. 2: it comprises main washboard 1, the profile of main washboard 1 is frustum of a cone hollow structure, the closing in section 2 of main washboard 1 has been welded to connect overlap joint cylinder 3, the center shaft of overlap joint cylinder 3 coincides with the center shaft of wet tank, the flared end 4 of main washboard 1 has been welded to connect folded structure 5, the flared end 4 of main washboard 1, the corresponding part that folded structure 5 forms is welded with reinforcing pad 6, the outer ring surface of reinforcing pad 6 is welded to connect the tube structure of storage tank equipment, the conical surface of main washboard 1 is furnished with some liquid macropores 7 excessively.

The inclined-plane of folded structure 5 had liquid aperture 8, and crossed liquid aperture 8 and be radially uniformly distributed;

The inner of overlap joint cylinder 3 is provided with the flanging section 9 of turning up, and flanging section 9 is positioned at the inner side of the closing in section 2 of main washboard 1, and the closing in section 2 of main washboard 1 is welded to connect flanging section 9.

Calculate washboard in the present invention and effectively stop that area formula is as follows:

Washboard effectively stops area A:

$A=\frac{\mathrm{\π}}{4}{D_i}^2-\frac{\mathrm{\π}}{4}{d}_0^2-n_1\frac{\mathrm{\π}}{4}{d}_1^2-n_2\frac{\mathrm{\π}}{4}{d}_2^2,$

Wherein: equipment barrel interior diameter Di, it is d1 that middle overlap joint cylinder manhole diameter d 0, n1 crosses liquid diameter macropores, arranges n2 according to the actual requirements and crosses liquid hole diameter d2.

Choose the low-temperature liquid buffering tank that diameter Di is 7000mm, reinforcing pad specification T200 × 200 × 18mm, overlap joint cylinder manhole diameter d 0=2100mm, crosses liquid macropore specification 20 × Ф 280, d1=280mm, crosses liquid aperture specification 6 × Ф 100, diameter d 2=100mm.

Washboard effectively stops area A:

$A=\frac{\mathrm{\π}}{4}{D_i}^2-\frac{\mathrm{\π}}{4}{d}_0^2-n_1\frac{\mathrm{\π}}{4}{d}_1^2-n_2\frac{\mathrm{\π}}{4}{d}_2^2=31279110{\mathrm{mm}}^2,$

Inner canister cross-sectional area B:

$B=\frac{\mathrm{\π}}{4}{D}_i^2=38465000{\mathrm{mm}}^2,$

Effectively stopping that the ratio that area accounts for whole inner canister cross-sectional area is 0.814 through calculating washboard, being greater than the requirement of 0.8 in relevant criterion.

Above specific embodiment of the utility model has been described in detail, but content being only the preferred embodiment that the utility model is created, the practical range created for limiting the utility model can not being considered to.All equalizations done according to the utility model creation application range change and improve, and all should still belong within patent covering scope of the present utility model.
