Description

Technical Field

[0001] This application relates to the field of saccharin sodium production, and in particular to a filter cake decolorization device for saccharin sodium production. Background Art

[0002] The filter cake decolorization device for saccharin sodium production is a device specifically designed to remove color impurities in the filter cake during the production of saccharin sodium. During the production of saccharin sodium, intermediates or by-products are formed, and these substances may carry colors and need to be removed to ensure the purity and appearance quality of the final product. The filter cake decolorization device is usually a step after the ammoniation reaction, aiming to remove the colored substances in the ammoniated liquid to make it more pure.

[0003] For example, the Chinese patent with the publication number CN219663072U discloses a filter cake decolorization device for saccharin sodium processing, including a filter barrel placed on the horizontal ground of the saccharin sodium processing factory building and an upper cover clamped on the top of the filter barrel. A filtering mechanism is installed above the upper cover. The filtering mechanism includes a first motor, a rotating shaft, a first transmission component, a transmission rod, a limit clamping sleeve, a fixing component, a second transmission component, an outer filter cylinder and an inner filter cylinder. The bottom of the first motor is connected to the rotating shaft through a coupling, and the first transmission component is wound around the circumferential side above the rotating shaft;

[0004] The technical solution recorded in this scheme can quickly filter the saccharin sodium solution and the internal impurities through the setting of the filter barrel, improve the working efficiency of filtration, and increase the filtration efficiency of saccharin sodium to a certain extent and reduce the filtration time of saccharin sodium.

[0005] However, this technical solution only uses one decolorizing agent for decolorization, and the commonly used decolorizing agent in the production of saccharin sodium is activated carbon powder. This decolorization method requires a large amount of activated carbon powder, and activated carbon powder is not easy to regenerate, resulting in high production costs and inconvenience in use. Summary of the Utility Model

[0006] This application provides a filter cake decolorization device for saccharin sodium production to solve the problems raised in the above background art.

[0007] The above technical objectives of this application are achieved through the following technical solutions:

[0016] Furthermore, the filtering assembly includes a pressure pump, and the input end of the pressure pump is communicated with the turbid liquid interface.

[0017] By adopting the above solution, since the input end of the pressure pump is communicated with the turbid liquid interface, it is convenient to pump out the turbid liquid inside the decolorizing tank, pressurize it, and then pump it into the filter for filtration and separation.
