Mould for the preparation of catalyst
Technical field
The present invention relates to a kind of mould, especially relate to a kind of mould for the preparation of catalyst.
Background technology
The activity of catalyst not only depends on its chemical composition, and is also relevant with its institutional framework.The same catalyst is due to the otherness of mould, and its activity falls far short, so the mould of catalyst has special significance.difference due to mould, the specific area of catalyst, pore size, the physical propertys such as particle can vary, thereby cause in a catalytic unit, the catalyst whole surface area of packing into is little, granular size is irregular, have a strong impact on conversion per pass, the Production Gain rate is impacted, and time-consumingly take a lot of work again, affect operating efficiency, because the locking device structure of common mould is simpler, there is no positioner, in frequent die sinking, form removal, easily damage in the locked mode process, cause the interlock of up and down die body in the locked mode process unreasonable, deviation easily appears in the location, affect quality and the production efficiency of product.
Summary of the invention
The object of the invention is to provide a kind of mould for the preparation of catalyst, with the purpose of implementation structure more stable and stronger, accurate positioning, raising specific surface area of catalyst and production efficiency.
For achieving the above object, the present invention can take following technical proposals:
Mould for the preparation of catalyst of the present invention comprises the upper and lower die body that mutually snaps together; The distolateral wall of described upper and lower die body one is hinged, and other end sidewall is provided with locking device; Longitudinally correspondingly respectively in the die cavity of upper and lower die body be evenly equipped with the vertical muscle that many cross sections are isosceles trapezoid; Between described adjacent vertical muscle longitudinally spaced set many sliver transvers sections are arranged is the horizontal bar of circular arc; The upper surface of described horizontal bar, vertical muscle is in same level; The action of horizontal bar is less than the degree of depth of formed mold slots between vertical muscle; The described mold slots degree of depth is 6.41mm; Described locking device comprises and is arranged on the upper die body sidewall the symmetrical trapezoidal plate that has two grooves, is arranged on two Connection Blocks on the lower mold body sidewall; Be hinged with the clamp that is used in conjunction with described trapezoidal plate on described Connection Block; Have positioning through hole corresponding to a pair of position on described trapezoidal plate, Connection Block.
The invention has the advantages that by in die cavity between adjacent vertical muscle longitudinally the many sliver transvers sections of spaced set be the horizontal bar of circular arc, the average decile of vertical muscle, make the catalyst granules of production more regular, stable, increase the specific area of catalyst granules; By mould being reinforced locking, Stability Analysis of Structures at the symmetrical clamp that has the trapezoidal plate of two grooves and be arranged on the lower mold body sidewall on the upper die body sidewall; By having positioning through hole corresponding to a pair of position in upper and lower die body edge, make that the mold integral structure is more stable, accurate positioning; For further increasing the specific area of catalyst, change the mold slots degree of depth into 6.41mm.

The specific embodiment
As shown in Fig. 1,2,3,4,5,6, the mould for the preparation of catalyst of the present invention comprises the upper die body 1, the lower mold body 2 that mutually snap together; Described upper die body 1, the distolateral wall of lower mold body 2 one are hinged, and other end sidewall is provided with locking device; Longitudinally correspondingly respectively in the die cavity of upper die body 1, lower mold body 2 be evenly equipped with the vertical muscle 3 that many cross sections are isosceles trapezoid; 3, described adjacent vertical muscle longitudinally interval 19mm to be provided with many radiuses be 8.688mm, arc length is the circular arc horizontal bar 4 of 13.8mm, the average decile of vertical muscle 3, makes the catalyst granules of production more regular, stable; The upper surface of described horizontal bar 4, vertical muscle 3 is in same level; The action of horizontal bar 4 is less than the degree of depth of vertical 3 formed mold slots 5 of muscle; Described mold slots 5 degree of depth are 6.41mm, have further increased the specific area of catalyst granules; Described locking device comprises and is arranged on upper die body 1 sidewall the symmetrical trapezoidal plate 6 that has two grooves, is arranged on two Connection Blocks 7 on lower mold body 2 sidewalls, be hinged with on described Connection Block 7 with described trapezoidal plate 6 on the groove clamp 8 of pegging graft and to be used in conjunction with, in use clamp 8 is plugged in the groove of trapezoidal plate 6, thereby realizes the reinforcing of mould is locked; Have positioning through hole corresponding to a pair of position 9,10 on described trapezoidal plate 6, Connection Block 7, be respectively arranged with alignment pin in positioning through hole 9,10, can realize the accurate location of mould.
