Title: Dust-free air sucking device for engine cooling air
Inventor: OKAMOTO KAZUTOSHI
IPC: F01P7/08
Filed: 1988-11-11
Abstract: PURPOSE:To make it possible to prevent an engine from overheating even during blowing off of dust from a dust-free air sucking means by locating an auxiliary dust- free air sucking section of the dust-free air sucking means at an external position where dust can hardly be sucked into. CONSTITUTION:A dust-free air sucking means 6 having a main dust-free air sucking section 8 and an auxiliary dust-free air sucking section 9 is disposed on the sucking side of a cooling fan 1 for cooling an engine E. In this arrangement, the auxiliary dust-free air sucking section 9 is located at a position which is outside of the main dust-free air sucking section 8 and at which dust can hardly be sucked, and a dust blowing-off means 11 is arranged being faced to the main dust-free air sucking section 8. In this arrangement, during blowing-off operation of an air motor 28, blowing-off air 13 is blown through the main dust-free air sucking section 8 from the inside to the outside thereof so as to blow off dust 7 sticking to the outside of the main dust-free air sucking section 8. During the blowing-off process of this dust 7, the cooling fan 1 continuously rotates in a normal direction so as to suck a large volume of the outside air through the auxiliary dust-free air sucking section 9 to which only a slight quantity of dust sticks, and accordingly the engine E is sufficiently cooled, thereby it is possible to prevent the engine E from overheating.

Abstract: PURPOSE:To obtain a mud material having excellent corrosion resistance to molten pig iron and slag and free from the phenomenon of abrupt expansion of taphole, by adding a volatile organic carbon compound to a refractory material composed of silicon iron nitride, carbon, kaolin clay and other component and kneading the mixture. CONSTITUTION:The objective mud material is produced by adding a volatile organic carbon compound to a refractory composed of >=20 pts.wt. of a silicon iron nitride, 5-25 pts.wt. of carbon, 5-15 pts.wt. of kaolin clay and the remaining part of other refractory component and kneading the mixture. The silicon iron nitride used as a raw material is produced by nitriding ferrosilicon and composed of 70-80% of Si3N4 and the remaining part composed mainly of metallic Fe and FeSi. The Si3N4 has a nature of covalent bond substance and high oxidation resistance in itself and is hardly wettable with molten pig iron or slag, however, it slowly decomposes at >=1400 deg.C to release nitrogen. The nitrogen is supposed to react with kaolin clay in the presence of carbon and fixed in the refractory to improve the density and corrosion resistance of the mud material.
