Special double cone rotary vacuum dryer silicon nitride material works Description: silicon nitride, chemical formula Si3N4, is an important structural ceramic material. It is a super-hard material, itself has lubricating properties, and abrasion, as atomic crystal; antioxidant at high temperature. And it is also resistant to thermal shock, heated in air to above 1000 ℃, rapidly cooled and then heated rapidly, it will not shatter. It is because of the silicon nitride ceramic having such excellent characteristics, people often use it to make bearings, gas turbine blades, mechanical seal ring, permanent mold and other mechanical components. If high-temperature silicon nitride ceramic heat transfer and difficult to manufacture engine parts heating surface can not only improve the quality of diesel fuel savings, but also improve the thermal efficiency. Our country and the United States, Japan and other countries have developed such a diesel engine. Application of silicon nitride materials: silicon nitride used advanced refractory, such as in conjunction with sic for SI3N4-SIC refractories for blast furnaces and other parts of the body; if combined with BN for SI3N4-BN material separation for horizontal continuous casting ring. SI3N4-BN horizontal continuous casting line separating ring is a fine structural ceramic materials, uniform structure, with high mechanical strength. Thermal shock resistance, and will not be moist liquid steel, in line with Pente process requirements. Nitride special double cone rotary vacuum dryer works: SZG double cone rotary vacuum dryer type double cone rotating tank, special double cone rotary vacuum dryer intermediate silicon nitride cylindrical, conical ends, at the top of the cone is designed to open a head feed (doubles manhole) and the other end is a discharge valve. Cans vivo divided into three intermediate jacket heating medium can be steam, hot water or thermal oil circulation, insulating layer of the base fine glass wool, minimal power consumption; inner running material. Work tank in a vacuum state, to the jacket into a thermal oil, hot water or steam for heating heat medium, heat transfer to the wet material through the tank wall. Since the tank body in a vacuum, a variety of materials in the vehicle (including water) can rapidly vaporized under vacuum conditions at a lower temperature, and the rotating of tank so that the material constantly up and down, inside and outside turning, constantly updated material surface in contact with the wall, to make full use of the heat conducted by the walls, to speed up the drying rate of materials, increase drying efficiency, and to achieve uniform drying purposes. Evaporation of the solvent (water vapor) after the wet material absorbs heat out through vacuum exhaust pipe is withdrawn. Cryo midway through the system (using water or frozen brine) cooling, in order to achieve the purpose of recycling, saving production costs and improve the working conditions of the vacuum pump, but also reduce environmental pollution.
