Sampling device for reaction kettle

Abstract

The invention relates to the technical field of chemical equipment, particularly to a sampling device for a reaction kettle. The sampling device for the reaction kettle includes the reaction kettle and a discharge opening, wherein the discharge opening is formed in the bottom of the reaction kettle; a sampling pipe is arranged in the middle of the reaction kettle; a seal head is arranged at the other end of the sampling pipe; a draw rod is arranged in the sampling pipe, and the draw rod is longer than the sampling pipe; a valve is arranged at a sampling opening; a clamping block is arranged at the end of the draw rod inside the sampling pipe, and the size of the clamping block is matched with the inner diameter of the sampling pipe; the other end of the draw rod penetrates the seal head and is provided with a stop block. The sampling device for the reaction kettle adopting the technical scheme avoids wastes and achieves accurate sampling.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a reactor sampling device. Background technique [0002] Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, medicine, food and other production users and various scientific research and experimental projects. According to the reaction conditions, the structure, function and configuration accessories of the reactor are designed. From the beginning of the feed-reaction-discharge, the preset reaction steps can be completed with a high degree of automation, and the temperature, pressure, mechanical control, reactant or product concentration and other important parameters in the reaction process are strictly controlled. regulation. [0003] At present, monitoring the reaction situation of the material in the reaction kettle of chemical industry is to take a sample by setting a sampling tube on the reaction kettle. When sampling, it is necessary to rel...

AI Technical Summary

Problems solved by technology

[0006] The reaction kettle sampling device adopting the above technical scheme has the following advantages: when sampling is required, by controlling the pull rod and pulling out the pull rod, the liquid to be sampled will enter the sampling tube under the action of force, and take a sample at the sampling port. After the sampling is completed, push the sampling liquid in the drawing rod into the reaction kettle until the engaging block of the drawing rod is against the reaction kettle. When sampling is required again, just repeat the above operation. The reactor sampling device overcomes the waste of materials caused by each release of the sample in the current technology, and at the same time, there will be no inaccurate sampling caused by mixing the previous sampling liquid
