Abstract
The utility model relates to a three -layer ladder ring packs belongs to petrochemical technical field. This ladder ring packs and is made by the metal, its outer wall overlook be circular, it is inside have a symmetry first to the 6th leaf structure, first all have the arc tongue piece towards outer wall raised to the 6th blade on, first have the breach that corresponds with the tongue piece to the 6th blade on. The utility model provides a three -layer ladder ring packs has three -layer leaf structure crisscross each other, has better compressive property, and 120 degrees are strideed across to its blade for space between packing and packing is incomparable to mutual intussusception.
Description
Technical field
The utility model relates to a kind of three layers of ladder ring packing, belongs to technical field of petrochemical industry.
Background technology
Dumped packing is the critical piece in petrochemical industry; Its stuctures and properties has material impact to the disposal ability of packed tower, product quality and technical-economic index.Dumped packing, according to its shape difference, can be divided into the various ways such as Raschig ring, Pall ring, cascade ring, flat ring, conjugate ring and rectangular saddle ring.
In actual production, often there is mutual intussusception phenomenon between dumped packing, greatly affect production efficiency, reduce product quality.
Summary of the invention
The utility model wants technical solution problem to be: the shortcoming overcoming above-mentioned technology, provides a kind of three layers of ladder ring packing reducing intussusception probability.
In order to solve the problems of the technologies described above, the technical scheme that the utility model proposes is: a kind of three layers of ladder ring packing, described ladder ring packing is made of metal, and its outer wall is overlooked rounded, has the first blade between 2 of 120 degree of circular arcs that described outer wall inner periphery is separated by; Described outer wall inner periphery also has the second blade be centrosymmetric with the center of circle of the relative described outer wall of described first blade; On described outer wall inner periphery, between be rotated counterclockwise 60 degree of circular arc gained respectively on described first blade two summit 2, there is Three-blade; The quaterfoil that the center of circle that described outer wall inner periphery also has described outer wall relative to described Three-blade is centrosymmetric; On described outer wall inner periphery, between be rotated counterclockwise 60 degree of circular arc gained respectively on described Three-blade two summit 2, there is the 5th blade; Described outer wall inner periphery also has the 6th blade be centrosymmetric with the center of circle of the relative described outer wall of described 5th blade; Described first to the 6th blade is all in the arc towards hexagon central protuberance; Described first to the 6th blade height is 1/3rd of described outer wall height, and described first and second blades are positioned at one end of described outer wall, form the first ladder; Described 5th and the 6th blade is positioned at the other end of described outer wall, forms the 3rd ladder; Described third and fourth blade is positioned at described first and the 3rd centre of ladder, forms the second ladder; Described first to the 6th blade all has towards the arc tongue piece of described outer wall projection; Described first to the 6th blade have the breach corresponding with described tongue piece.
Such scheme further improves and is: described outer wall offers window; Described window totally three layers is corresponding with the position of the described first to the 3rd ladder respectively.
Such scheme further improves and is: the upper and lower two ends of described outer wall have crimping.
Such scheme further improves and is: the height of described outer wall and the equal diameters of described circle.
Three layers of ladder ring packing that the utility model provides have three layers of interlaced blade construction, there is good compressive property, its blades span 120 degree, the space between filler and filler is made to be not enough to mutual intussusception, further, have the effect that 6 blades play reinforcement altogether, strengthen outer wall intensity, higher pressure can be born, prevent the intussusception that breakage causes.Blade also has tongue piece, prevents damaged protrusion from going deep within outer wall further.Meanwhile, overall hole is comparatively large, and liquids and gases are less by pressure, and outer wall also offers window, are further decreased through pressure.

Detailed description of the invention
Embodiment
Three layers of ladder ring packing that the present embodiment provides, as shown in Figure 1, this filler is made of metal, and its outer wall 1 is overlooked rounded, and the inwall of outer wall 1 is circumferentially shaped with the first to the 6th blade.Wherein, the first blade 2 is between 2 of the 120 degree of circular arcs in interval; The center of circle of the inwall circumference of the second blade 3 and the first blade 2 opposite outer walls 1 is centrosymmetric; Three-blade 4 by two summits of the first blade 2 counterclockwise after the inwall of outer wall 1 circumferentially rotates 60 degree of circular arcs between 2 of gained, the center of circle of the inwall circumference of quaterfoil 5 and Three-blade 4 opposite outer walls 1 is centrosymmetric; 5th blade 6 by two summits of Three-blade 4 counterclockwise after the inwall of outer wall 1 circumferentially rotates 60 degree of circular arcs between 2 of gained, the center of circle of the inwall circumference of the 6th blade 7 and the 5th blade 6 opposite outer walls 1 is centrosymmetric.
First to the 6th blade is all in the arc towards hexagon central protuberance, and the 1/3rd, first and second blades highly equaling outer wall 1 height are positioned at one end of outer wall 1, form the first ladder; 5th and the 6th blade is positioned at the other end of outer wall 1, forms the 3rd ladder; Third and fourth blade is positioned at first and the 3rd centre of ladder, forms the second ladder; First to the 6th blade all has towards the arc tongue piece 8 of outer wall 1 projection; First to the 6th blade all have the breach corresponding with tongue piece 8.
As shown in Figure 2, outer wall 1 offers window; Window totally three layers, offers height corresponding with the first to the 3rd ladder, like this can more effective increase flow, reduction pressure; Outer wall about 1 two ends have bead structure to gain in strength; The height of outer wall 1 and the equal diameters of outer wall 1.
The utility model is not limited to the concrete technical scheme described in above-described embodiment, and in addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacing and being formed, and are the protection domain of the utility model requirement.
