| description | The utility model discloses a crystallization device without blocking a bottom valve, and belongs to the technical field of chemical equipment. Comprising a crystallization kettle with a reflux condenser, a stirrer in the crystallization kettle and a discharging structure at the bottom of the crystallization kettle, the discharging structure comprises an upper expansion valve on a discharging port in the bottom of the crystallization kettle, a shutoff valve connected with the discharging port of the upper expansion valve through a discharging pipe, a leakage detecting port in the lower side of the discharging pipe, a liquid discharging valve on the leakage detecting port and a collecting groove under the leakage detecting port. A valve element of the upper expansion valve can extend upwards by 100-150 mm, and the pipe diameter of the valve element is larger than or equal to 60 mm. The problem that the bottom valve is blocked can be thoroughly solved, materials can be discharged at a time, meanwhile, in order |
