An automatic sampling device for chemical testing

Abstract

The invention relates to a sampling apparatus and especially relates to an automatic sampling apparatus for chemical engineering detection. The invention aims to solve technical problems by providing an automatic sampling apparatus used for chemical engineering detection, which allows automatic sampling and is free of influence on a chemical reaction. The automatic sampling apparatus includes a pedestal, a reaction tank, a support, stirring blades, a connecting rod, a worm rod, a worm gear, a first bearing seat, a second rotary shaft, a first rotary shaft, a first support rod, a motor, etc. The reaction tank and the support are welded to the top of the pedestal. The reaction tank is located at the left side of the support. A placing table is welded to the left side of the reaction tank. A sample groove is disposed on the top of the placing table. The apparatus allows automatic sampling and is free of influence on a chemical reaction. By means of the worm rod and the worm gear, the motor, when driving the stirring blades to stir reactants, can drive a nut to move left and right.

Description

technical field [0001] The invention relates to a sampling device, in particular to an automatic sampling device for chemical testing. Background technique [0002] Sampling refers to selecting a representative sample from the target object, which is commonly explained as taking a small number of samples from a large number of items or materials. [0003] In the process of chemical synthesis, the control of the reaction process and the end point of the reaction is a crucial factor. This process directly affects the yield of the reaction and the quality of the product. In order to clearly know the state of the material reaction, it is required to frequently take samples to detect some corresponding indicator, and the state of the reaction material is more complicated, and the material is often dangerous. The traditional sampling method generally stops stirring first, and then uses a sampling spoon to sample. The sampling process is dangerous, and stopping the stirring will af...

Problems solved by technology

[0005] In order to overcome the chemical synthesis process, the control of the reaction process and the reaction end point is a crucial factor. This process directly affects the yield of the reaction and the quality of the product. In order to clearly know the state of the material reaction, frequent sampling and detection are required. Some corresponding indicators, but the state of the reaction material is more complicated, and the material is often dangerous. The traditional sampling method generally stops stirring first, and then uses a sampling spoon to sample. The sampling process is more dangerous, and stopping the stirring will affect the reaction process. , or because the state of the reaction cannot be accurately grasped because of the inability to sample, the shortcoming that has a certain impact on the yield of the reaction and the quality of the product, the technical problem to be solved in the present invention is to provide a kind of automatic sampling and does not affect the chemical reaction process.
