Problems solved by technology

[0002] Catalyst carriers are usually porous structures. By adopting porous structures, the surface area is larger, and more catalysts can be attached. However, the existing porous ceramic catalyst carriers are cumbersome to process, the operation process is complicated, and the demoulding is inconvenient, resulting in production low efficiency

Embodiment 1

[0017] like figure 1 As shown, a catalyst carrier forming mechanism disclosed in this embodiment includes a lower mold 101 and an upper mold 102, the upper mold is relatively fixed, and a cavity is provided inside the lower mold 101 for placing raw materials to form a carrier , a partition 103 is arranged in the cavity, so that the partition divides the cavity to form upper and lower parts, and a molding cavity 104 is formed below the partition 103, and when the raw material is input, the raw material enters the cavity in a row Inside, a feed pipe 105 is provided on the side wall of the lower mold 101 above the partition 103, and the lower end of the feed pipe 105 passes through the partition 103 and connects with the molding cavity. 104 are connected, and multiple sets of feeding pipes can be set up, so that the raw materials can be evenly input into the molding cavity from multiple angles. An inner mold 106 is arranged on the lower end surface of the middle part of the upper...

Embodiment 2

[0019] In this embodiment, for the convenience of installation, one end of the lower mold bracket 108 close to the upright column 114 is hinged on the upright column 114 , and the other end thereof is connected to the side wall of the lower mold 101 through bolts.

[0020] Further preferably, in this embodiment, in order to facilitate operation, a flange 109 is provided on the side wall of the lower end of the lower mold 101, and a card slot 110 is provided on the flange 109, and one end of the bolt is rotated It is connected to the side wall of the lower mold support 108, and the other end of the bolt is snapped into the inside of the slot 110 and fixed by a nut.

Embodiment 3

[0022] In this embodiment, in order to increase the surface area of ​​the porous structure, preferably, the stem 107 is a hollow structure, and convex lines are provided on the stem 107 to make the cross section wavy. In this embodiment, the core column is made to have a hollow structure, so that a hollow ring-shaped structure can be formed on the molded carrier, and the cross-section of the ring-shaped structure is wavy, which can further increase its surface area, and it can be attached. Catalyst more.

Abstract

The invention discloses a catalyst carrier forming mechanism. The catalyst carrier forming mechanism comprises a lower die and an upper die, wherein an empty chamber is formed in the inner side of the lower die; a separating plate is arranged in the empty chamber; a forming chamber is formed below the separating plate; a feeding pipe is arranged on the sidewall, above the separating plate, of the lower die; the lower end of the feeding pipe passes through the separating plate and communicates with the forming chamber; an inner die is arranged on the lower end surface of the middle part of the upper die and passes through the separating plate; the lower end surface of the inner die is as high as the lower end surface of the forming chamber; core columns which are distributed at equal intervals are arranged on the lower end surface of the inner die; the upper end surfaces of the core columns are positioned below the separating plate; a lower die bracket is arranged below the lower die. According to the catalyst carrier forming mechanism, the inner die provided with the core columns is adopted to form a porous structure on a produced die, so that the surface area of the die can be increased, and as a result, the attaching quantity of a catalyst can be greatly increased.

Description

technical field [0001] The invention relates to a catalyst carrier molding mechanism. Background technique [0002] Catalyst carriers are usually porous structures. By adopting porous structures, the surface area is larger, and more catalysts can be attached. However, the existing porous ceramic catalyst carriers are cumbersome to process, the operation process is complicated, and the demoulding is inconvenient, resulting in production low efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a catalyst carrier forming mechanism, which can improve the problems existing in the prior art. By adopting an inner mold provided with a core column, a porous structure is formed on the produced mold, which can increase the surface area of ​​the mold and greatly increase the catalyst capacity. the amount of attachment. [0004] The present invention is realized through the following technical solutions: [0005] A catalyst carrier formin...
