Description

Technical Field

[0001] The present invention relates to the technical field of catalyst carrier production, and specifically to a mixing device and method for producing an alumina catalyst carrier. Background Art

[0002] ‌Alumina catalyst carriers are a widely used type of industrial material, mainly used for loading catalytic active components to improve catalytic efficiency. Alumina catalyst carriers are usually white powder or formed solids, with various forms such as strips, spheres, ingots, etc., suitable for different types of reactors. Their properties such as density, pore structure, specific surface area, etc. have an important impact on catalytic performance;

[0003] ‌In the production of alumina catalyst carriers, each raw material component needs to be fed into a mixing device for mixing treatment, and then through processes such as drying, forming, and calcination to complete the preparation work, so as to obtain the alumina catalyst carrier.

[0004] Referring to a mixing device for an organic carrier additive in the production of conductive silver paste disclosed in the patent application with the publication number CN110841538A, this mixing device can stir silver powder, organic adhesives, etc. in multiple directions to improve the stirring efficiency. At the same time, it makes the mixing of silver powder and organic adhesives more uniform, improves the stirring efficiency of the device, and at the same time, improves the mixing uniformity of silver powder and organic adhesives.

[0005] The above-mentioned mixing device can mix and stir silver powder, organic adhesives, etc. by using a multi-directional stirring method. Currently, most mixing devices mix by a stirring shaft and stirring blades. A large number of bubbles are easily generated during the rotation and stirring of the stirring blades, making the alumina catalyst carrier rich in a large number of bubbles, which affects the mixing effect. And a large number of bubbles will affect the quality of the alumina catalyst carrier and easily have a negative impact on the performance of the alumina catalyst carrier. When performing subsequent processes such as drying and forming, it is necessary to defoam the mixed alumina catalyst carrier, increasing the production difficulty. Summary of the Invention

The actuating frame 33 is triggered through the track line formed on the surface of the protrusions 32;

[0084] An actuating frame 33 is slidably arranged in the rectangular frame 30. The length of the actuating frame 33 is the same as the inner length of the rectangular frame 30, and the width of the actuating frame 33 is less than the inner length of the rectangular frame 30, so that the actuating frame 33 moves in a single direction in the rectangular frame 30.

[0086] It is worth noting that when the bubbles in the raw material are processed: by providing a processing mechanism, when the built-in toggle member toggles the raw material, the coaxial member 22 thereon drives the outer gear ring 24 to rotate, and since the outer gear ring 24 is meshed with a plurality of No. 3 gears 28, the No. 3 gear 28 is driven to follow the rotation, and the driving arm 29 is eccentrically arranged on the No. 3 gear 28, the rotation of the No. 3 gear 28 can be transmitted through the driving arm 29, and the rectangular frame 30 is pushed to move back and forth in the annular cavity 9, so that the raw material flowing out of the conveying channel 12 can be reciprocated for debubbling. Specifically, the dynamic The No. 1 metal wire 42 provided in the action frame 33 contacts the raw material in a reciprocating state, which can quickly puncture a large number of bubbles in the raw material, reduce the content of bubbles in the raw material, and reduce the subsequent defoaming workload. At the same time, a trigger bar 31 is provided, and the action frame 33 contacts the protrusion 32 of the trigger bar 31 through the sensing arm 34. When the action frame 33 moves back and forth, it is guided by the trajectory line of the protrusion 32 and squeezed by the return spring 36, so that the action frame 33 superimposes a left and right swing amount in the rectangular frame 30, which can perform multi-directional puncture processing on the bubbles in the raw material, further improving the elimination accuracy;

[0087] In the embodiment of the present invention, the action element further includes:
