Abstract

The invention discloses a mold for manufacturing a catalyst. The mold for manufacturing the catalyst comprises an upper mold body and a lower mold body, wherein the upper mold body and the lower mold body are buckled. The distance of the bottom of a cavity and the edges is 8mm respectively. A plurality of longitudinal bars are respectively, correspondingly and evenly arranged in mold cavities along a longitudinal direction, wherein the cross sections of the longitudinal bars are in the shape of isosceles trapezoids. A plurality of transverse bars are arranged among adjacent longitudinal bars at intervals by equant spaces along the longitudinal direction, wherein the cross sections of the transverse bars are arc-shaped. The upper surfaces of the transverse bars and the longitudinal bars are in the same horizontal plane. The chord height of the transverse bars is smaller than the depth of mold grooves formed among the longitudinal bars. A locking device comprises a trapezoidal board and two connection seats, wherein the trapezoidal board is arranged on the side wall of the upper mold and symmetrically provided with two through grooves and the two connection seats are arranged on the side wall of the lower mold body. Clamping boards matched with the trapezoidal board for use are hinged on the connection seats, and the trapezoidal boards and the connection seats are respectively provided with a pair of positioning through holes which are in opposite positions. The mold for manufacturing the catalyst has the advantages of being stable in structure, precise in positioning, and capable of further improving internal capacity of the mold and regularity of catalyst particles.

Description

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 quality of implementation structure more stable and stronger, accurate positioning, raising catalyst prod and the purpose of 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 of mutual fastening; 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; Upper and lower die body die cavity bottom is respectively 8mm with the distance at edge; 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; 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; 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; Be further to increase the mould inside volume, change the distance at mold cavity bottom and edge into 8mm.
