Intelligent rapid digestion device

Abstract

The invention relates to an intelligent rapid digestion device. The intelligent rapid digestion device is characterized in that: a digestion device is connected to a cooling device, a lifting device is located above the middle of the digestion device and the cooling device and is fixed to the rear side of the digestion device, an air flue is arranged between the digestion furnace and the casing ofthe digestion device, a blowing fan is fixedly connected to the interior of the air flue at the inner wall of the casing, a fan is arranged on the interlayer of the casing of a cooling tank of the cooling device and the cooling tank or on the side of the inner wall of the casing, air holes are arranged in the inner wall of the cooling tank, a lifting stand column of a lifting device is fixedly connected to the rear side of the digestion device, a rotating support arm is connected to the lifting stand column, the rotating support arm can be automatically lifted, dropped and rotated so that labor is saved and the air cooling and water cooling processes are alternate in the same zone and thus cooling time is saved, the digestion pipe is circularly cooled through water so that the cooling time of the furnace is shortened, and the digestion pipe and a waste discharge hood are provided with frosted ports so that the overflow of the exhaust gas is reduced.

Description

technical field [0001] The invention relates to an intelligent rapid digestion device, which belongs to the technical field of chemical equipment. Background technique [0002] The high temperature digestion device mainly converts organic samples into inorganic substances under high temperature and strong acid conditions for subsequent analysis and detection. This device is widely used in basic scientific experimental research in agriculture, biology, medicine, industry, etc., as well as digestion treatment before protein determination. For example, the determination of nitrogen and phosphorus content in soil or plant samples in the field of ecology requires the conversion of organic nitrogen and phosphorus into inorganic nitrogen and phosphorus in a high temperature and strong acid environment. Another example is the Kjeldahl method commonly used in food to determine protein content, which also needs to be digested by this device. Concentrated sulfuric acid reacts with nit...

AI Technical Summary

Problems solved by technology

At present, none of the existing devices have taken measures to cool down the digestion furnace body, usually natural cooling, and the speed of digestion heating is fast, but the cooling speed is very slow, which limits the process of digestion of the next batch of samples. The traditional digestion device widely used for digestion When the furnace is used to measure the protein content in food, it needs to be set at a high temperature of 420°C, so the cooling rate of the furnace body and the natural cooling of the digestive tube will be very slow, the waiting time will be long, the operation is cumbersome, and the degree of automation is not high, which seriously affects the work efficiency; Usually, it takes about 90 minutes for the digestion furnace to cool down from 380°C to 150°C. In addition, the exhaust gas generated during the digestion process is directly discharged into the air through the fume hood or discharged into the sewer through the hose, causing environmental pollution and waste of water resources.

The determination of a large number of samples is usually involved in scientific research and food testing. The above shortcomings of traditional digestion devices severely limit the digestion rate and the entire experimental process, reduce work efficiency, and cause serious pollution to the atmosphere.
