Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a bag-type dust removal device. Background Art

[0002] In the production process of maltodextrin, the solid dextrin dried in the dextrin tower is transported into the cyclone separator through the air conveying system to separate the gas phase and the solid phase, while reducing the temperature of the dextrin to prevent it from hardening.

[0003] The patent document with authorization announcement number: CN212594602U discloses "a bag-type dust removal device for maltodextrin", which involves starting a servo motor. The output end of the servo motor drives the turntable to rotate, and then drives the arc-shaped toggle block to rotate. During the rotation of the arc-shaped toggle block, the arc-shaped block will be continuously toggled, so that the arc-shaped block will continuously move up and down, and then drive the connecting block to continuously move up and down. The connecting block drives the air outlet pipe to move up and down through the fixed plate, so that the multiple screening plates below can also move up and down, so that the screening plates are constantly in a vibrating state, and the connecting plates at both ends of the screening plates will continuously compress the springs. The elasticity of the springs prolongs the up and down vibration time of the screening plates, so that the dextrin powder on the screening plates falls quickly and is discharged and collected through the discharge port.

[0004] Although the device prolongs the up and down vibration time of the screening plate through the elasticity of the spring, so that the dextrin powder on the screening plate falls quickly, the dextrin powder on the screening plate is only processed by vibration, which may result in unclean processing and it is inconvenient to clean the screening plate.
