Production monitoring multi-stage sampling device for chemical product processing and sampling method of production monitoring multi-stage sampling device

Abstract

The invention provides a production monitoring multi-stage sampling device for chemical product processing and a sampling method of the production monitoring multi-stage sampling device, belongs to the technical field of chemical sampling, and aims to solve the problem that illegal personnel easily steal chemical products in a large stirring tank due to lack of a protective structure at a sampling pipe orifice of an existing multi-stage sampling device. Theproduction monitoring multi-stage sampling device includes a stirring tank body; a sampling part is arranged on the front side of the stirring tank body; a protection box fixed at the lower part of the front side of the stirring tank body is arranged outside the front end of the sampling part; a locking box is arranged on the left end face of the protection box, a driving piece is magnetically attracted to the left end face of the locking box, and a locking part and a driving screw rod are arranged in the locking box. An upper box door of the protection box is locked through the locking part, so that when a illegal personnel want to open the upper box door of the protection box, the box door of the protection box can be opened by virtue of a driving piece carried by a sampling person, the illegal personnel are difficult to steal chemical products in the stirring tank body, and the use reliability of the multistage sampling device is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical sampling, and more specifically relates to a production monitoring multi-stage sampling device and a sampling method for chemical product processing. Background technique [0002] Chemical industry is the abbreviation of "chemical technology", "chemical industry", "chemical engineering" and so on. Any technology that uses chemical methods to change the composition and structure of substances or to synthesize new substances belongs to chemical production technology, that is, chemical technology, and the resulting products are called chemicals or chemical products. During the processing of chemical products, sampling operations are usually required, and when sampling chemical liquids in large stirring tanks, multi-stage sampling devices are usually used. [0003] For example, application number: CN201710138108.0 The present invention relates to a sampling device, in particular to an automatic samp...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a production monitoring multi-stage sampling device and sampling method for chemical product processing, to solve the problem that the current multi-stage sampling device samples the chemical liquid in a large stirring tank due to the general The multi-stage pipe runs through and is fixed on the tank wall of the large mixing tank, and then the valve on the multi-stage pipe is opened to discharge and sample the chemical liquids of different layers in the large stirring tank, but the gap between the multi-stage pipe penetrating the tank wall and the tank wall Leakage is very easy to occur in the room, resulting in the loss and waste of chemical liquids, and it is also easy to cause fire hazards and other safety hazards, and the sampling nozzle of the existing multi-stage sampling device lacks an effective protective structure, making it easy for illegal personnel. The chemical products in the large mixing tank are stolen, which reduces the reliability of the multi-stage sampling device when used
