Description

Technical Field

[0001] The utility model relates to the technical field of sulbactam sodium production equipment, in particular to an activated carbon stirring decolorization device. Background Art

[0002] In the later stage of the production of sulbactam sodium, it is necessary to use an activated carbon stirring decolorization device to adsorb impurities and decolorize, and then introduce the filtrate into the crystallizer, slowly add the solvent while lowering the temperature to form a slurry, and finally discharge the slurry to the separation device.

[0003] CN 219128365 U discloses an activated carbon decolorizing filter, which includes a device body, a support leg installed at the bottom of the device body, a discharge pipe installed at the bottom of the device body, a decolorizing tank installed inside the device body, and a mounting bracket installed at the top of the decolorizing tank. The filter rotates clockwise by rotating the stirring rod, stirring the activated carbon, liquid and product inside the decolorizing tank to rotate clockwise, and then cooperates with the driven gear ring to drive the activated carbon, liquid and product inside the decolorizing tank to rotate counterclockwise, and the decolorizing reaction efficiency of the activated carbon to the product is improved by double rotation. By controlling the sealing plate to move downward from the bottom of the decolorizing tank, the filter cover is moved out of the groove at the bottom of the decolorizing tank. After part of the waste liquid inside the decolorizing tank is discharged from the mesh on the surface of the filter cover, it is convenient to filter out the product and activated carbon inside the decolorizing tank. However, there are the following problems when using it: the distance from the bottom of the decolorizing tank to the filter cover is greatly affected by the overall design height of the filter. If it is too long, the overall height of the filter will increase. If it is too short, the filtering efficiency will be affected. Summary of the invention
