Embodiment 1

[0020] Such as Figure 1 to Figure 3 As shown, the catalyst granulation device includes a driving motor 12, a cylindrical hole die 1 and a pressure wheel 2 cut inwardly with the cylindrical hole die 1; the inner wall of the cylindrical hole die 1 is provided with a feed channel 3; the feed channel 3 has an inlet and a The outlet; the inlet is connected with a feed hopper 4, and the outlet faces the tangent between the cylindrical hole mold 1 and the pressing wheel 2; the outer wall of the cylindrical hole mold 1 is uniformly provided with a plurality of through holes 5; the inner wall of the through hole 5 is provided with a surface increasing mechanism; The surface increasing mechanism is a tooth pattern; the rotating shaft of the drive motor 12 is connected with a reducer 13 and a transmission shaft 14 in sequence; the free end of the transmission shaft 14 is connected with the pressing wheel 2; the output shaft of the reducer 13 and the transmission shaft 14 are coupled Dev...

Embodiment 2

[0023] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that a solid column 6 is provided in the through hole 5; the side wall of the solid column 6 is connected with a connecting rod 7, and the free end of the connecting rod 7 is connected with the inner wall of the through hole The outer wall of the solid column 6 is provided with a surface-increasing mechanism; the surface-increasing mechanism is a tooth pattern; the surface-increasing mechanism can also be other structures that increase the surface area of ​​the catalyst such as threads, protrusions; the solid column 6 makes the catalyst raw material made hollow , the gear on the inner wall increases the contact area between the catalyst and the reactant, so that the chemical reaction takes less time and achieves a better catalytic effect.

Embodiment 3

[0025] Such as figure 1 As shown, the difference between this embodiment and Embodiment 1 and Embodiment 2 is that the catalyst granulation device also includes a cutting motor 8 and two transmission wheels 9; a circular saw blade 10 is transmission-connected between the two transmission wheels 9; The saw blade 10 is evenly provided with multiple cutting edges 11; the cutting edge 11 of the circular saw blade 10 is in contact with the outer wall of the cylindrical hole die 1; the rotating shaft of the cutting motor 8 is connected with any transmission wheel 9; the cutting motor 8 drives a transmission wheel 9 to rotate , and then drive another transmission wheel 9 to rotate to make the circular saw blade 10 rotate, and the extruded catalyst is cut off.

[0026] Such as Figure 1 to Figure 3 As shown, when the embodiment 1 to the embodiment 3 are in use, the catalyst raw material is added from the feed hopper 4, and the catalyst raw material enters the feed channel 3, and it e...

Abstract

The invention discloses a catalyst granulation device and mainly solves the problems that catalysts produced by existing catalyst granulation devices adopt solid granular structures, have smaller contact areas when participating in chemical reactions with reactants and have poor catalytic effects. The catalyst granulation device comprises a feeding port, a cylindrical hole mold and a press wheel internally tangent with the cylindrical hole mold; a feeding channel is formed in the inner wall of the cylindrical hole mold and comprises an inlet and an outlet; the inlet is communicated with a feeding hopper and the outlet faces the position where the cylindrical hole mold and the press wheel are tangent; a plurality of through holes are uniformly formed in the outer wall of the cylindrical hole mold. With the adoption of the catalyst granulation device, the catalysts have larger contact area with the reactants in chemical reactions, the chemical reactions take less time, the catalytic effect is better, and the catalyst granulation device has high practical value and promotional value.

Description

technical field [0001] The invention relates to the field of catalyst production, in particular to a catalyst granulation device. Background technique [0002] The composition, chemical properties and quality of the catalyst itself do not change before and after the reaction; its relationship with the reaction system is like the relationship between a lock and a key, and it is highly selective; a catalyst does not catalyze all chemical reactions For example, manganese dioxide plays a catalytic role in the thermal decomposition of potassium chlorate to speed up the chemical reaction rate, but it does not necessarily have a catalytic effect on other chemical reactions; some chemical reactions are not the only catalyst, such as potassium chlorate can be catalyzed in the thermal decomposition There are also magnesium oxide, iron oxide and copper oxide and so on. [0003] The catalyst produced by the existing catalyst granulation device has a solid granular structure. When the c...
