Technical Field
[0001] The utility model relates to the technical field of production auxiliary devices for plasticizers of organic chemical products, and particularly relates to a specific gravity measuring device in the production of chlorinated environmental protection plasticizers. Technical Background
[0002] The main component of chlorinated environmental protection plasticizer is chlorinated fatty acid methyl ester, which is synthesized by reacting fatty acid methyl ester with chlorine gas. In this reaction, chlorine atoms replace hydrogen atoms in fatty acid methyl ester to make fatty acid methyl ester become chlorinated fatty acid methyl ester. During the production process of chlorinated environmental protection plasticizer, it is necessary to continuously track its reaction process, that is, to monitor its specific gravity at any time. The existing technology generally uses a special chemical electronic hydrometer, and the defects are as follows: First, the special chemical electronic hydrometer is expensive. Usually, a special chemical electronic hydrometer costs thirty or forty thousand yuan, and for a more precise one, it even needs more than one hundred thousand yuan. In the actual production process, there are many positions where the specific gravity of materials needs to be measured, which requires equipping multiple special chemical electronic hydrometers, resulting in too large a one-time investment; Second, the maintenance cycle of these special chemical electronic hydrometers is short and the maintenance cost is high. Summary of the Invention
[0003] The purpose of the utility model is to provide a specific gravity measuring device in the production of chlorinated environmental protection plasticizers with simple and compact structure, low production and maintenance costs, convenient and efficient operation, and reliable measurement results, so as to replace the special chemical electronic hydrometer and thus reduce the investment and maintenance costs of instruments and equipment.
[0004] To achieve the above purpose, the specific gravity measuring device in the production of chlorinated environmental protection plasticizers of the utility model includes a glass sight glass 1, a circulation pump 2, a conventional hydrometer 3, a sight glass material inlet valve 4, a sight glass material outlet valve 5 and a reaction kettle 6; the inlet pipeline of the circulation pump 2 is connected to the bottom of the reaction kettle 6, and the outlet pipeline is divided into two paths. One path is connected to the top of the reaction kettle 6, and the other path is connected to the inlet end of the glass sight glass 1 after connecting the sight glass material inlet valve 4. The outlet end of the glass sight glass 1 is connected to the upper side of the reaction kettle 6 after connecting the sight glass material outlet valve 5 through a pipeline; the conventional hydrometer 3 is placed in the glass sight glass 1.

[0006] 1. This device can detect the density during the production process of plasticizer under closed conditions, can replace the special chemical electronic hydrometer, reduce the enterprise's dependence on the special chemical electronic hydrometer, and thus reduce the investment and maintenance costs of instruments and equipment.

[0012] The specific operation of using the specific gravity measuring device in the production of the chlorinated environmental protection plasticizer of the present utility model is as follows:
[0013] Simultaneously open the circulation pump 2, the sight glass material inlet valve 4, and the sight glass material outlet valve 5, and make the opening degree of the sight glass material inlet valve 4 greater than that of the sight glass material outlet valve 5.
