Vacuum concentration crystallization pot
The entire equipment can be divided into four parts: heating evaporation chamber, heating jacket, vapor-liquid separator, and stirrer.
The parts of the equipment that are in contact with the product use1Cr18Ni9TiThe heating evaporation chamber is made like a cylindrical shell. In order to facilitate installation and maintenance, it is processed in two sections using materials of different thicknesses and connected by flanges. The back cover can be processed into a hemispherical, dish-shaped, or cone-shaped body. The lower cylinder is equipped with a sight glass to observe the boiling condition of the solution, the height of the mist entrainment, the concentration of the solution, the size and distribution of crystals, etc.; the hole in the pot body is for convenience of cleaning and maintenance. A heating jacket is welded to the lower part of the pot, and its height is determined by calculating the area required for evaporation.
Anchor-type stirrers are currently used for mixing. The speed6-15change/At present, the mixing installation is installed on the lower shaft, which can shorten the length of the shaft and facilitate installation and maintenance.
