Abstract

The invention discloses a sampling and pressure measuring device for a reaction kettle and relates to the technical field of reaction kettles. The device is characterized in that a connecting pipe of which two ends are provided with flanges is arranged on an opening in the top of the reaction kettle; the connecting pipe is fixedly connected with a sampling pipe through the flange at the upper end; the sampling pipe is coaxially communicated with the connecting pipe; and a pressure gauge is connected in the middle of the connecting pipe. The sampling and pressure measuring device has the beneficial effects that the structure is simple, the sampling is conveniently performed when needed, a sampling port can be conveniently opened and closed, and impurities in air are prevented from being mixed; and moreover, the operation of the reaction kettle is not influenced, the pressure in the reaction kettle is monitored in real time, and the limited space at the upper end of the reaction kettle is saved.

Description

Technical field:

[0001] The invention relates to the technical field of reactors, in particular to a sampling and pressure measuring device for reactors. Background technique:

[0002] In the pharmaceutical process, the materials are put into the reactor for stirring and mixing reaction. During the entire operation of the reactor, it is necessary to monitor the reaction of the materials in the reactor. In the prior art, the way to check the reaction of the materials in the reactor is to open the inlet of the materials on the reactor for sampling and testing. This sampling method is very inconvenient, and opening the material inlet of the reactor can easily bring in impurities contained in the air, resulting in quality problems of the reactants. At the same time, to monitor the pressure in the reactor, a manometer is independently installed on the upper part of the reactor, which occupies a limited space. Invention content:

[0003] The technical problem to be solved by ...
