Description

Technical Field

[0001] The utility model relates to the technical field of sodium petroleum sulfonate production, in particular to a sodium petroleum sulfonate production filtering device. Background Art

[0002] Sodium petroleum sulfonate is an important surfactant commonly used in the manufacture of detergents, dyes, cosmetics, biological products, and other industrial fields. Its production is generally based on petrochemical techniques such as nitration, reduction, oxidation, and sulfonation of nitrobenzene, and it plays a crucial role in the petrochemical industry. However, conventional production techniques often introduce a range of impurities, potentially impacting subsequent production and processing, product quality, and efficiency.

[0003] When the applicant was making this application, after searching, he found that a Chinese patent disclosed a "filtration and impurity removal device for the production of petroleum sodium sulfonate", and its application number is "CN202322705288.X". The patent mainly includes a body, the bottom end of the body is fixedly connected to a support leg, the bottom end of the support leg is fixedly connected to a support foot, the top of the body is fixedly connected to a feed port, the bottom end of the body is fixedly connected to a discharge port, the top of the inner side of the support leg is fixedly connected to a fixed plate, the inner side of the bottom end of the fixed plate is fixedly connected to a connecting plate, and the middle part of the upper surface of the connecting plate is movable. A trigger block is installed, and a filter plate is set up to filter out the residue in the sodium petroleum sulfonate, and the residue flows onto the filter plate. When the residue on the filter plate needs to be cleaned, the handle is grasped and pulled outward to extract the filter plate from the chute a. After extraction, it is cleaned and can be put back into use. This is convenient to operate and improves the processing quality of sodium petroleum sulfonate. However, manual removal of impurities alone will increase labor consumption and may also delay the removal of impurities, causing impurity accumulation, affecting the filtration of industrial products, reducing work efficiency, and greatly increasing the waste of human resources. To this end, we propose a sodium petroleum sulfonate production filtration device to solve the above problems. Utility Model Content
