Hydrothermal reaction kettle

Abstract

The invention discloses a hydrothermal reaction kettle. The hydrothermal reaction kettle comprises a base; one corner of the upper surface of the base is provided with a control switch group; the input end of the control switch group is electrically connected with the output end of an external power source; the upper surface of the base is provided with a water tank; the upper surface of the water tank is provided with a circular notch; the left and right sides of the upper surface of the base are separately provided with a hydraulic cylinder; the inlets and outlets of the hydraulic cylinders are connected with an external oil pump; the telescopic ends of the hydraulic cylinders are connected with fixing arms; a kettle body is fixedly connected between the two fixing arms; the diameter of the kettle body is less than the diameter of the circular notch; the center lines of the kettle body and the circular notch are on the same axis; the middle part of the lower surface of the kettle body is provided with a discharge pipe; the middle part of the discharge pipe is provided with a discharge valve. The hydrothermal reaction kettle disclosed by the invention is convenient to disassemble; the interior of the kettle body is convenient to clean or vulnerable parts are convenient to replace; quick heating and cooling of the kettle body are convenient; the use is convenient; a solution can be quickly stirred; and reactants attached to the inner wall of the kettle body are convenient to scrape.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a hydrothermal reactor. Background technique [0002] Hydrothermal reactor is also called polymerization reactor, digestion tank, high-pressure digestion tank, high-pressure tank, reactor, hydrothermal synthesis reactor, digestion tank, hydrothermal synthesis reactor, and experimental reactor. The hydrothermal reaction kettle is a closed container that can decompose insoluble substances. It can be used for sample pretreatment in the analysis of atomic absorption spectroscopy and plasma emission, and can also be used for small-dose synthesis reactions. It can also use strong acid or strong Alkaline and high temperature and high pressure airtight environment to achieve the purpose of quickly digesting insoluble substances, it is a good assistant for digesting samples when determining trace elements and trace elements.

AI Technical Summary

Problems solved by technology

It burns gas to heat the heat-conducting oil, and then heats the kettle body. The kettle body is equipped with a heat-conducting layer, a gas combustion chamber and an insulation layer, which makes the structure of the kettle body more complicated, and it is more inconvenient and troublesome to use when cooling the kettle body. In addition, it scrapes the wall by using the stirring paddle, the effect is not obvious, there are defects in use, and further improvement is needed
