Vacuum distillation granulation system

Equipment Introduction

Vacuum distillation granulation systemMainly used by colleges, research institutions, and production enterprises for melting, vacuum casting, or distillation of metal materials under high vacuum or protective atmosphere conditions. Distillation is achieved by heating a compound solution to the boiling point of a certain element, and installing a condensation collection container at the top to collect the distilled metal, achieving the distillation collection effect.

Structural Description
1. This equipment consists of a high vacuum chamber, furnace frame, vacuum system, melting device, condensation collection device, furnace cover opening device, induction power supply device and control system, water cooling tube integration device, etc.
2. High vacuum chamber: Both the furnace body and furnace cover adopt a double-layer water-cooled layer structure, and the inner and outer walls are made of 304 stainless steel. To ensure vacuum degree, the inner walls are mirror polished; External wall sandblasting and electrolytic treatment. A sealing groove is opened on the flange plane of the furnace body. Adopting fluororubber "0" ring vacuum sealing. There are suction holes, electrode devices, temperature measuring devices, inflation interfaces, etc. on both sides of the furnace body. The furnace cover is equipped with observation windows, venting devices, mechanical explosion-proof devices, etc
2. Furnace frame: The furnace frame is assembled from steel sections and CNC folded plates, used to support the furnace body and serve as an operating platform. It is also integrated with the electrical control box, making the operation more user-friendly.
3. Vacuum system: composed of one direct coupled pump, one molecular pump, inflation valve, deflation valve, pneumatic high vacuum valve, vacuum pressure gauge (± Pa), and vacuum pipeline.
4. Melting device: composed of induction coils, insulation sleeves, graphite sleeves, and melting crucibles, with temperature measuring thermocouples at the bottom that can automatically adjust the temperature according to the process.
5. Condensation collection device: There is a molybdenum transition tube directly above the melting crucible, connecting the melting crucible and the condensation collector, and equipped with a thermocouple for temperature measurement, which can monitor the temperature at any time. The condensation collection device adopts a double-layer water-cooled structure.
6. Furnace cover opening device: using two gas springs, opening backwards and equipped with a locking device
7. Induction power supply device and control system: The power supply adopts ultrasonic induction power supply, which is energy-saving, noise free, fast heating speed, and can automatically heat up and cool down according to the program instrument. The control system is equipped with overcurrent, overvoltage feedback and protection circuits. The electrical control panel box is made according to Siemens standards, with a beautiful structure and easy operation.
8. Water cooling tube integrated device: composed of various pipeline valves and other related devices, it has the functions of water pressure under pressure, water cut-off sound and light alarm, automatic power cut-off, ensuring safe operation. All the places that need water cooling on the vacuum chamber and power coil have been connected, and there is a main inlet and outlet. Customers only need to connect the inlet and outlet of the peripheral cooling circulating water system with the main inlet and outlet pipes of the furnace before use
