Vacuum Concentrated Crystallization Pot

Product Overview

The entire equipment is divided into four parts: the heating evaporation chamber, the heating jacket, the vapor-liquid separator, and the stirrer. Based on extensive research on jacket heating, we have designed internal heating and internal circulation heating, as well as the evaporation and crystallization pot. Users have reported that the evaporation effect is superior to that of external heating [jacket heating].

       The equipment's contacting parts are made of 1Cr18Ni9Ti. The heating evaporation chamber, resembling a cylindrical shell, is constructed in two segments using materials of different thicknesses for ease of installation and maintenance, and is connected with flanges. The bottom can be machined into hemispherical, disc-shaped, or conical shapes on the vessel body. Both upper and lower cylindrical sections are equipped with sight glasses to observe the boiling state of the solution, the height of entrained mist, the concentration of the solution, the size and distribution of crystals, etc. The opening in the pot body is designed for easy cleaning and maintenance. The heating jacket on the lower part of the pot is焊接, and its height is determined by calculating the required evaporation area.

       Mixers currently mostly use anchor-type mixers with a speed of 6-15 rpm, and the mixing installation currently employs a lower shaft mount, which can shorten the shaft length and facilitate installation and maintenance.

       This equipment is composed by four parts: evaporation room, heating jacket, vapor-liquid separator and stirring device. Our factory has made a lot of research based on jacket heating and designed the internal heating, internal circulating heating, evaporation and crystallizing pan. The users all think the evaporation result is 1.8 times than external heating (jacket heating).

       All the parts that may contact with the product are made of 1Cr18Ni9Ti. The heating & evaporation room is like a cylinder shell body. In order to make repairing more convenient, materials of different thickness are used to process in two sections which are connected by the flange. The sealing bottom can be processed into hemispheric shape, dish ship and cone shape. The lower cylinder is installed with viewing mirror to observe boiling condition of the solution, entrainment height, solution concentration, crystallization dimension and distribution condition. Opening inside the boiler body is for easy cleaning and maintenance. Heating jacket is welded on lower boiler part of which the height is determined based on calculated area necessary for evaporation.

       Anchored type stirring device with rotation speed of 6-15 rotations/min is used for stirring purpose. Lower-shaft installation method is adopted which may shorten shaft length and makes it easier for installation and maintenance.
