Description
Technical Field
The utility model belongs to chemistry experiment field specifically relates to a hydrothermal-thermal treatment automation experiment device.
Background
The desire of the public to blue sky and white cloud makes the research of new energy become popular. The Hydrogen Evolution Reaction (HER) and the Oxygen Evolution Reaction (OER) in the field of electrocatalysis are the theoretical basis for preparing hydrogen, fuel cells, lithium air batteries and other next-generation energy sources [13-15], so that the research on various hydrogen evolution and oxygen evolution catalytic materials is also concerned. Such as phosphides, selenides, sulfides, etc., represented by NiCoP, the preparation process of such materials has in common the following "hydrothermal-thermal treatment" scheme, as shown in fig. 1.1 [16-20 ]. The 'hydrothermal-thermal treatment' process has strong universality and high operation standardization degree, so the process is taken as an entry point, an unmanned thinking tide is introduced into an electrocatalysis experiment, and an unmanned 'hydrothermal-thermal treatment' experiment platform is explored and researched.
According to the artificial experimental experience, the 'hydrothermal-thermal treatment' experiment is decomposed into: substrate material treatment, drug treatment, hydrothermal experiment and heat treatment.
The method comprises three steps of processing and cutting a substrate material, cleaning and drying. For example, the preparation of self-supporting hydrogen evolution and oxygen evolution catalysts, nickel foam, copper foam, carbon paper and the like are required as substrate materials. Taking foamed nickel as an example, the hydrothermal experiment can be carried out after cutting, cleaning and drying. Generally, firstly, cutting foamed nickel by using a scissors or a slicing machine, then repeatedly cleaning the foamed nickel by using acetone, dilute hydrochloric acid, distilled water, ethanol and the like, and finally drying the foamed nickel in a vacuum oven to obtain a clean sample, wherein the process of completing the description of two lines in the literature can be completed in 2-3 hours; the reason for this is that the three devices, the slicer, the ultrasonic cleaning machine and the vacuum oven, work independently and require the intervention of researchers to complete the corresponding tasks.
The medicine treatment relates to the weighing of medicines, and for granular medicines, the adhesion degree of the medicines is different, some medicine particles are easy to separate, and some hydrate particles are easy to agglomerate. Weighing is not easy, and particularly when the weight is in milligram order, accurate weighing requires considerable patience. Taking the preparation process of NiCoP as an example, a certain amount of nickel chloride, cobalt chloride, ammonium fluoride and urea are weighed firstly, then distilled water is added and stirred uniformly, and the obtained solution is used for a subsequent hydrothermal experiment. The weighing process has the difficulty that the chemicals are bonded to different degrees, such as urea particles are easy to separate, and ammonium fluoride or some hydrate particles are easy to agglomerate. At present, an accurate weighing device, namely a weighing device with a weight sensor and a display, is adopted, and everyone needs to be very patiently worried when weighing various medicines. The operation time is too long, and the manual influence is large during the operation.
The hydrothermal equipment adopts a reaction kettle.
The heat treatment is generally carried out in a tube furnace. The tube furnaces commonly used at present are novel high-performance high-energy-saving electric furnaces developed by adopting international advanced technology, and have various tube furnace types such as single tube, double tube, horizontal type, openable type, vertical type, single temperature zone, double temperature zone, three temperature zone and the like. The method is mainly applied to experiments and small-batch production of universities and colleges, scientific research institutions, industrial and mining enterprises and the like. The device has the advantages of safety, reliability, simple operation, high temperature control precision, good heat preservation effect, large temperature range, high temperature uniformity of the hearth, multiple temperature zones, optional atmosphere, vacuum-pumping furnace type and the like. A single set point or 30 segment programmable controller may be selected. The energy-saving ceramic fiber material and the double-layer structure can reduce the surface temperature to normal temperature. The temperature equalizing area is long, the operation is simple and convenient, the sealing is reliable, the comprehensive performance index is higher, and the temperature equalizing device is at the leading level in China. The furnace tube can be made of heat-resistant steel, quartz glass, ceramic tube, etc. Use the tube furnace among the heat treatment process, present ordinary tube furnace sets up the quartz capsule including the box that has heating function in the box and holds the chamber, and the box both sides are sealed by sealed ring flange, and the quartz capsule is placed and is held the intracavity at the quartz capsule, and the crucible is placed in the quartz capsule. The quartz tube accommodating cavity of the tube furnace is large, and the crucible is a common crucible, so that only a crucible with a diameter much smaller than the inner diameter of the quartz tube is selected. Taking the preparation of the NiCoP catalyst as an example, the NiCoO nano rod obtained by hydrothermal method is washed and dried, and then is put into a tube furnace together with sodium hypophosphite powder, and the NiCoP hydrogen evolution catalyst is obtained by annealing under the protection of argon. At present, if a common tube furnace is used in the heat treatment process, a crucible containing a sample is difficult to keep stable when being placed in a quartz tube, and sealing flanges on two sides of the quartz tube are difficult to install.
