[0038] Working principle: when the device is used for impregnation molding of the catalyst carrier, in the initial state, the stop block 18 blocks the middle part of the blocking ring 19. The top end surface of each push rod 25 is flush with the filtering surface of the filter plate 16, and in this embodiment, the top end surface of each push rod 25 is parallel to the filtering surface of the filter plate 16.

[0039] Firstly, the powder or granular catalyst carrier material is added into the shell 6 through the feeding pipe 7. At the same time, the first motor 2, the second motor 8 and the liquid pump 29 are started.

[0040] After the second motor 8 is started, the output shaft of the second motor 8 drives the first rotating shaft 9 to rotate, and the first rotating shaft 9 drives the first spiral conveying blade to send the powder or granular catalyst carrier material into the impregnation tank 1 through the discharge port 11.

[0041] After the liquid pump 29 is started, the liquid pump 29 pumps out the impregnation liquid in the collection tank 27. The impregnation liquid flows into the impregnation tank 1 through the second connecting pipe 30, the liquid pump 29 and the first connecting pipe 10.

[0042] After the first motor 2 is started, the output shaft of the first motor 2 drives the stirring shaft 3 to rotate, and the stirring shaft 3 drives the stirring rod 4 to stir and mix the impregnation liquid and the powder or granular catalyst carrier material, thereby accelerating the impregnation molding.

[0043] After the impregnation is completed, the first motor 2, the second motor 8 and the liquid pump 29 are turned off. Then the air cylinder 14 is started, and the telescopic shaft of the air cylinder 14 is retracted downward and drives the push plate 15 and the connecting shaft 17 to move downward synchronously.

[0044] When the push plate 15 moves downward, the push plate 15 drives all the push rods 25 to slide downward and disengage from the corresponding filter holes 26. All the filter holes 26 are opened.

[0045] When the connecting shaft 17 moves downward, the connecting shaft 17 drives the stop block 18 to open the middle part of the stop ring 19.

Then, the molded catalyst carrier is stacked on the filter plate 16, and the impregnation liquid flows to the collection tank 27 through the filter hole 26 of the filter plate 16 under the action of gravity.

[0046] Then the third motor 21 is started, and the output shaft of the third motor 21 drives the second rotating shaft 24 to rotate.

The catalyst carrier in the inner cylinder 23 is discharged through the discharge pipe 22.

[0047] When the catalyst carrier is transported in the inner cylinder 23, the impregnation liquid is flowed back to the inner wall of the outer cylinder 20 through the through hole of the inner cylinder 23. The impregnation liquid on the inner wall of the outer cylinder 20 flows back to the separation tank 12 and finally flows into the collection tank 27 through the filter hole 26.

[0048] After the conveying is completed, the air cylinder 14 is started again. At this time, the telescopic shaft of the air cylinder 14 extends upward and drives the push plate 15 and the connecting shaft 17 to move upward synchronously. In this process, the push plate 15 drives all the push rods 25 to reinsert into the corresponding filter holes 26, and the push rods 25 push the catalyst carrier in the corresponding filter holes 26. At the same time, the stop block 18 reseals the middle part of the stop ring 19.

[0049] When the top end surface of all the push rods 25 is flush with the filter surface of the filter plate 16 again, the air cylinder 14 can be turned off.
