In the process of operating the stainless steel stirring tank, its overflow protection device includes a cylinder body, a liquid discharge port arranged on the lower side of the cylinder body, a liquid discharge port arranged on the lower side of the cylinder body, and a liquid discharge port arranged in the middle of the upper end face of the cylinder body. The butt conduit, the air outlet opening on the upper end face of the cylinder body, and the columnar floating body directly below the butt conduit, are used to block the elastic gasket of the lower port of the butt conduit.
One end of the docking conduit of the equipment is connected to its overflow port, and the other end will extend into the cylinder during the operation; the elastic gasket is arranged on the upper end face of the columnar floating body. The overflow protection device can not only temporarily store the overflow, but also prevent the overflow within the range, feedback control the feeding device or issue an alarm signal.
The process requirements of the stainless steel stirred tank usually include the volume of the reactor, the maximum working pressure, the working temperature, the working medium and the corrosion condition, the heat transfer area, the stirring form, the speed and power, and the fittings of the nozzles, etc. . These requirements are generally reflected in the equipment design requirements list proposed by the process department in the form of tables and schematic diagrams.
In the process of mechanical design of the equipment, it is necessary to analyze the contents of the design requirements list. Usually, pressure, temperature, medium corrosion, etc. are the main factors to be considered in the mechanical design of stainless steel stirred tanks. If it is a complex process with more than two contradictions, it is necessary to find out its main contradiction. In general, pressure is the main contradiction in equipment design. It often plays a decisive role in the selection of materials, structure and shape of the equipment. Therefore, it must be considered first.
