Abstract
The utility model relates to a plate, particularly the plate structure of the freeze-drying box of a vacuum freeze dryer. The utility model adopts a split lapping partition strip structure. An upper partition strip and a lower partition strip are respectively welded on an upper plane plate and a lower plane plate and are inserted together then, and at last, outer frame strips are welded on four sides. Thus, the plate can be formed. The utility model is suitable for plates of various sizes. The partition strips and the plane plates have firm welding and high intensity, and the connecting welding seams of the partition strips and the plane plates are positioned on the inside of the plate, which can effectively prevent leakage.
Description
The utility model relates to a kind of flaggy, especially for the flaggy of frozen vacuum dryer.
Layer structure in traditional frozen vacuum dryer freeze drying box is such, and two is dull and stereotyped fixing with the moulding welding all around, forms the interlayer of hollow.The inside is divided into this space with the square steel bar of plurality of integral snakelike, can control the flow direction of heat-conducting medium like this, makes whole flaggy temperature even.But there are some problems at parting bead in this structure with dull and stereotyped being connected, and parting bead normally adopts plug welding or electric resistance welding with dull and stereotyped the connection now.If adopt plug welding to connect, because weld seam runs through interlayer and surface, and at the solder joint of flaggy surface shape in many projectioies.The necessary machining of these solder joints is smooth.Plug welding belongs to multiple spot and connects, and when being subjected to cutting force and stress deformation, is prone to weld cracking.In case this phenomenon takes place, will cause dielectric leakage and pollute medicine, cause enormous economic loss.Plug welding causes the Facing material inequality, surface weld place corrosion-vulnerable.If adopt electric resistance welding to connect parting bead with dull and stereotyped, parting bead and slab-thickness can not be too big, otherwise electric resistance welding can't be welded together with them.Therefore electric resistance welding only is used for the manufacturing of small-sized flaggy, and electric resistance welding and plug welding all belong to a connected mode, so bonding strength is all very low.
The purpose of this utility model provides a kind of layer structure of frozen vacuum dryer, this structure can be used for the flaggy of virtually any size size, and weld seam is dull and stereotyped inboard at flaggy, the no weld seam in surface, thus fundamentally avoid between parting bead and flat board the weldquality quality to the influence of product.
The utility model is achieved in that on the basis of original layer structure the monolithic parting bead with in traditional layer structure changes split type parting bead into.Parting bead is made up of two parts, and these two parts all have a convex shoulder.After being welded in them on the upper and lower flat board respectively, this two-part convex shoulder being overlapped mutually, thereby hold upper and lower two flat boards, make it can under vacuum condition, not make the upper and lower cokled surface distortion of flaggy because of the effect of internal pressure.
Compare with the whole parting bead in the original structure, the advantage of split type parting bead is the continuous welding that can adopt weld strength high, and weld seam does not destroy the globality of flaggy external surface dull and stereotyped inboard.Both made weld seam that crackle is arranged, and also can not make heat-conducting medium drain to the flaggy outside.With whole parting bead and flat board that electric resistance welding connects, though also can reach above-mentioned purpose, its welding is limited in scope, and can't make the large scale flaggy.Split type parting bead structure flaggy then can be used for making the flaggy of virtually any size.
Specific operation process of the present utility model is provided by following explanation and accompanying drawing:
The sketch of Fig. 1 frozen vacuum dryer
Fig. 2 layer structure figure
Fig. 3 parting bead sectional view
Illustrate according to the detail that the utility model proposes below in conjunction with Fig. 2, Fig. 3: layer structure is mainly by upper flat plate (2), following dull and stereotyped (3), last parting bead (5), following parting bead (4), outer moulding (1) composition.Upper flat plate (2) is welded together with last parting bead (5), and following dull and stereotyped (3) are welded together with following parting bead (4), and last parting bead (5) overlaps mutually with the convex shoulder of following parting bead (4), outer moulding (1) and upper flat plate, and following flat board is welded together.
The utility model specific implementation process is such, and upper flat plate (2) is lain on the platform, and parting bead (5) is put in superincumbent appropriate location, will go up with anchor clamps to weld after parting bead compresses, and following dull and stereotyped (3) are identical with following parting bead (4) welding method.The upper and lower flat board that welds is lumped together, the convex shoulder of upper and lower parting bead is overlapped.Use outer moulding (1) that dull and stereotyped up and down four edges sealing is welded at last, flaggy has just manufactured.
Claims (2)
1, a kind of layer structure, following dull and stereotyped mainly by upper flat plate, parting bead, outer moulding is formed, and it is characterized in that parting bead adopts split type parting bead, is made up of last parting bead and following parting bead.
2, a kind of flaggy according to claim 1 is characterized in that the last parting bead of split parting bead is welded on the upper flat plate, and following parting bead is welded in down on the flat board, and the convex shoulder of upper and lower parting bead overlaps mutually, plays the effect of the upper and lower flat board of tension.
