Multifunctional novel microwave digestion instrument

Abstract

The invention discloses a multifunctional novel microwave digestion instrument, and relates to the technical field of digestion instruments. The digestion instrument comprises a digestion instrument body, a microwave cavity, a filter box and a placement table, the microwave cavity is formed in the digestion instrument body, a horizontal partition plate is arranged in the microwave cavity, a motor is installed between the lower surface of the horizontal partition plate and the inner bottom surface of the microwave cavity, a transmission shaft is installed on the upper surface of the motor, a rotating disc is installed at one end of the transmission shaft, the placement table is mounted on the upper surface of the rotating disc, and a filter box is mounted on one surface of the digestion instrument body. Through the structure of a pressure relief device, a first clamping plate and a second clamping plate, pressure relief operation is automatically completed, bursting caused by too large pressure in a digestion pipe is avoided, through the structure of the filter box and an activated carbon adsorption layer, a gas exhausted from the digestion pipe is conveniently adsorbed and filtered, harmful substances and peculiar smells are removed, accumulation in the microwave cavity is avoided, the pollution to the working environment is avoided too, and the safety of equipment is improved.

Description

technical field [0001] The invention belongs to the technical field of digestion instruments, in particular to a novel multifunctional microwave digestion instrument. Background technique [0002] Digestion instrument is a commonly used sample pretreatment equipment. According to the degree of automation, it can be divided into semi-automatic digestion instrument and automatic digestion instrument; according to the principle, it can be divided into electrothermal digestion instrument and microwave digestion instrument. At present, there are relatively mature products, which are widely used. Widely, microwave digestion technology is to use microwave penetration and activation reaction ability to heat reagents and samples in airtight containers, which can increase the pressure in the sample preparation container and increase the reaction temperature, thereby greatly improving the reaction rate and shortening the sample preparation time. , and the reaction conditions can be con...

Problems solved by technology

[0004] The purpose of the present invention is to provide a new multifunctional microwave digestion instrument, through the pressure relief device, the first clamping plate and the second clamping plate structure, when the gas volume inside the digestion tube is too high during the digestion process, it will enter the pressure relief through the through hole Inside the device, push the first clamping plate and the second clamping plate to move upward to discharge the gas, and automatically complete the pressure relief operation to avoid the bursting of the internal pressure of the digestion tube. The structure of the filter box and activated carbon adsorption layer facilitates adsorption and filtration. The gas discharged from the digestion tube removes harmful substances and odors, avoids accumulation inside the microwave cavity, avoids polluting the working environment, improves the safety of the equipment, and solves the existing problems of excessive pressure and accumulation of harmful gases
