A design about 200 litres of emulsifying kettle

Abstract：A stirred tank as a emulsification vessel, its broad application prospects, especially in the chemical industry has been widely used. This passage is a design about 200 litres of emulsifying kettle. This design focus on tank’s design, agitator and transmission device selection, the selection of shaft sealing device, the finite element analysis and automatic control system. This article through the tank diameter ratio and loading coefficient to determine the tank diameter of 700 mm, height is 800 mm. The main characteristic is the elliptic welding of tank bottom and the lid can open. The pressure of inner tank is 1.3MPa and the pressure in the jacketed is 0.2MPa. In the stirred tank is the whole jacketed and turbine agitator with 6 blade and propeller diameter is 300 mm. The reaction kettle in this passage has a lot of advantages, such as simple structure, convenient processing, low energy consumption and automatic control system. Greatly save the human consumption, material consumption and financial consumption. And can guarantee the chemical products producing continuously.
