Glass precious metal purification device

In the application fields of optical glass, laser glass, sulfur based glass, semiconductor packaging glass, etc., trace or alloy precious metals (Pt, Rh, Au, Ir, etc.) are purified during glass melting to obtain high-purity precious metal raw materials and simultaneously improve the optical uniformity and chemical stability of the glass substrate.

Glass precious metal purification deviceIt can be used under both normal and reduced pressure conditions. Single batch processing capacity of 500ml-20000ml, tower section can be designed with temperature measurement and sampling ports; Customers can use standard specifications and configurations, which are suitable for various conventional materials and have good separation effects on various materials. The tower body is heated and insulated using electric heating belts and coating (transparent and visible), and the voltage can be manually adjusted. The insulation effect is good, and the distillation operation inside the tower can be directly observed. The control system mainly includes an intelligent temperature gauge (which can measure the tower kettle temperature, tower top temperature, tower section temperature, etc. through temperature sensors), a reflux ratio controller, a pressure regulator, etc. It mainly reflects the surface conditions of various control points in the distillation process.

Product composition:

It consists of a glass distillation tower, reflux ratio control system, tower kettle and body heating system, vacuum system, alarm system, and control system. It can meet various applications such as intermittent distillation, continuous distillation, azeotropic distillation, extraction distillation, and atmospheric and vacuum reaction distillation.

There are various models of main components such as distillation head, distillation tower, packing, temperature measurement, vacuum device, etc., which can be used for rotation and matching of different products. All glass instruments are connected using standard grinding ports, making installation and replacement very convenient. In addition to the traditional standard grinding port connection, there is also a ball milling port connection with better airtightness for the connection between accessories of glass instruments, which is particularly suitable for occasions with high vacuum requirements. The reflux ratio controller can not only be used for laboratory sample testing, but also can be extended to be used for distillation reflux control in medium and small-scale chemical production equipment by adding some accessories.

In addition to conventional products, our company can also undertake various non-standard customization services, and if necessary, the demand side must provide production drawings.

Product Features:

The main body of the tower kettle is made of glass, which has the characteristics of tight sealing, no leakage, and acid and alkali corrosion resistance. The heating temperature of the device can be adjusted and controlled, with automatic display of the top and bottom temperatures, and automatic control of reflux. Easy to operate, stable in operation, and reliable in data.

This device is a complete set of equipment with a compact structure, beautiful appearance, easy installation, and small footprint. Users only need to prepare a water source and power supply, and follow the instructions for simple installation before putting it into use. The main glass components are connected by standard or ball milling ports, fixed with alloy flanges, and have excellent airtightness and high vacuum distillation.

Digital display of vacuum degree during distillation, wide range of reflux ratio digital setting 99:1/1:99, automatic temperature control, digital display, convenient and intuitive. The installation bracket is a stainless steel floor frame structure.
