[0018] It should be noted that, unless otherwise defined, the technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The use of "belonging" in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this invention.

[0019] An embodiment of the spiral conveying and stirring device for molecular sieve production according to this utility model is as follows: Figures 1-2 As shown, the system includes a storage silo 1 with an inlet for receiving and storing molecular sieve material output from the slurry channel 17 of the filter.

Specifically, the spiral auger 4 includes a rotating shaft 5 and spiral conveying blades 6 mounted on the shaft. One end of the shaft is rotatably mounted to one end of the conveying cylinder, and a speed-regulating motor 7, which drives the shaft, is mounted on the conveying cylinder. The other end of the conveying cylinder has a discharge port 14, and an installation frame 8 is provided inside the discharge port for rotatably connecting the other end of the shaft. In this embodiment, the installation frame 8 includes an installation cylinder 9 for rotatably mounting the shaft, and two or more connecting rods 10 are evenly spaced axially between the installation cylinder and the conveying cylinder. In this embodiment, there are four connecting rods forming a cross shape. The shaft and the mounting cylinder can be connected via a bearing, which is housed within the mounting cylinder, and the shaft is rotatably connected to the bearing. To prevent the molecular sieve material from affecting the bearing, a bearing cover is provided on the outside of the bearing.

[0020] A flow-blocking plate 12 is movably installed at the discharge port 14 of the conveying cylinder 3. By inserting the flow-blocking plate, the area of ​​the discharge port can be reduced, thereby controlling the flow rate of the molecular sieve material at the discharge port. Specifically, an insertion hole 11 is provided on the cylinder wall of the conveying cylinder for the insertion or removal of the flow-blocking plate 12. In this embodiment, the insertion opening of the insertion hole 11 faces upward, that is, the flow-blocking plate 12 is inserted into the insertion hole from top to bottom. To ensure the stability of the flow-blocking plate, in this embodiment, the flow-blocking plate 12 has an "L" shaped structure, that is, the portion of the flow-blocking plate 12 located on the conveying cylinder has a bent portion 13 for locking onto the cylinder wall of the conveying cylinder.
