Sodium silicate, commonly known as Sodium Silicate, is a water-soluble silicate, and its aqueous solution is commonly known as water glass, which is a mineral binder. Its chemical formula is R2O·nSiO2, where R2O is an alkali metal oxide, and n is the ratio of the number of moles of silica to the number of alkali metal oxides, which is called the number of moles of water glass. The commonly used water glass in construction is an aqueous solution of sodium silicate. (Na2O·nSiO2)

◆Jinling Company is a professional manufacturer of vacuum paddle dryers. This model is the third-generation product improved and designed by our company.

◆In 2003, the company carried out a systematic innovation and improvement design, mainly for thermal expansion, concentricity, shaft seal, discharge valve, transmission structure, stirring form, main shaft strength, shaft heating, bearing assembly structure, mechanical seal internal structure, etc. On the previous page, the mechanical seal is fully used for vacuum drying operations, which greatly improves the sealing performance and service life. It can be adapted to manufacture large-scale high vacuum rake dryers.

◆ The mechanical seal structure is mainly a precision seal structure used to keep the vacuum rake dryer in high vacuum for a long time and effectively prevent impurities from entering the material. Generally, single end face machine seal, corrugated machine seal and double end face machine seal are selected. The end face materials are generally graphite, silicon carbide, and alloy steel materials.

◆ In order to ensure the airtightness and the service life of the dryer, a series of innovative designs and processing have been carried out especially for materials such as salts, liquids and solvents with high wear resistance and corrosiveness, so as to increase the amount of shaft runout and the expansion and extension of the equipment , Stability and service life have been doubled. The company is currently a professional manufacturer of vacuum paddle dryers in China.

◆ Adopting Jinling self-developed and designing different rake blade structures to adapt to the drying of materials under different working conditions: spiral belt type, copy plate type, disc type, triangular stirring paddle type, coulter type and other structural forms, and can be designed according to the design of the shaft Heating form to increase the specific surface area and greatly improve the drying efficiency.
