| titleOfInvention | Crystallization kettle for improving crystallization efficiency of coarse product of bis-hydroxyethyl piperazine |
| abstract | The utility model discloses an improve crystallization kettle of biethyl piperazine coarse product crystallization efficiency, including the crystallization kettle body, threaded connection has the top cap on the outer wall of crystallization kettle body top, and top cap top outer wall center department installs driving motor through the bolt, the driving motor output rotates through the shaft coupling and is connected with the axis of rotation, install the stirring rake through the bolt on the outer wall of axis of rotation one side, and install the scraper blade through the bolt on the one end outer wall that the axis of rotation was kept away from to the stirring rake, it is connected with four connecting axles to rotate through the connecting piece on the outer wall of axis of rotation bottom, and the connecting axle is kept away from the one end of axis of rotation and is passed. The utility model discloses a board is shed in the board that shed, and it is internal at the crystallization kettle that the board will treat the bis hydroxyethyl piperazine of crystallization shed, has improved the dispersion degree of treating the bis hydroxyethyl piperazine raw materials of crystallization greatly, has improved the thermal absorption rate to bis hydroxyethyl piperazine to improve crystallization efficiency. |
