Abstract

The invention discloses a production system for preparing sulpho tobias acid, wherein the production system comprises a grinding box body; the bottom of the grinding box body is welded with a supportcolumn. In the production system, a servo motor drives a grinding disc to rotate through two engagements, and at the same time, a spring can continuously apply downward pressure to a second movable plate. Therefore, when massive sulpho tobias acid is ground into a small state by the grinding disc, the grinding disc can move downwards and performs continuous grinding, and at the same time, a cylindrical pin on a worm wheel drives a sliding plate to move up and down, so that downward pressure applied to the second movable plate is periodically changed, the grinding effect is better, and sulpho tobias acid ground into powder is also convenient to disperse all around and falls down from a filter screen. The grinding device completes the crushing process in the sulpho tobias acid production system conveniently, the working efficiency is higher than that of manual crushing, moreover, a lot of labor costs are saved, the crushed sulpho tobias acid is uniform, and the value of finished productsis greatly improved.

Description

technical field [0001] The invention relates to the technical field of preparation of chemical raw materials, in particular to a production system for preparing sulfonated turezic acid. Background technique [0002] Sulfonated Tuidelic acid can be used as an intermediate in the synthesis of reactive dyes, photosensitive materials and organic dyes. Reactive dyes, photosensitive materials and organic dyes are widely used in the textile industry, plate making industry, and dye industry, and the application fields are further expanding. Therefore, the demand for salt-free sulfonated turezic acid as an intermediate is also constantly increasing. Large, with broad market prospects and development space. [0003] In actual production, the preparation of sulfonated tunic acid must go through four major steps 1 sulfonation, 2 sulfonated liquid refining, 3 acid analysis, 4 pressure filtration, 5 pulverization, wherein the product formed by the fourth cloth in the existing production ...
