Title: Melt reduction method of powder and granular ore by vertical type furnace
Inventor: INATANI TOSHIHIRO
IPC: F27B1/16
Filed: 1982-10-28
Abstract: PURPOSE:To perform advantageous melt reduction at a low cost without using costly electric power by reactive gaseous flow of a relatively low temp. by making use of the reducing waste gas produced in a vertical furnace by melt reduction for preliminary reducing and by-product gas for powder and granular ore. CONSTITUTION:Preheated air is blown through tuyere groups 5, 5' into a vertical furnace 3 where the packed layer of a carbonaceous solid reducing agent is fired and the reducing waste gas produced in the furnace 3 is discharged from an evacuation port 6. part of the waste gas is supplied 6' to the bottom of a preliminary reduction furnace 2 to dry and heat the powder and granular ore charged in the furnace 2, thereby reducing preliminarily the ore. The partially reduced ore produced in such a way is blown together with the preheating air through a waste ore port 7 and tuyeres 5, 5' into the furnace 3. The partially reduced iron blown together with the preheating air in a high temp. region formed in the furnace 3 is immediately heated and is easily melted. While the iron drops toward the lower part of the furnace 3, the iron is reduced to form a molten metal and molten slag, whereby the smelting is accomplished. The molten metal accumulating on the hearth is removed at a proper time from a tapping port 10 to the outside of the furnace 3. The molten slag is treated in a similar way.

Abstract: PURPOSE:To prevent oil from mixing in operating gas by connecting both chambers to generate a lip pressure of an oil scraper seal equal to or not less than tightening force of a spring, when a pressure in the intermediate chamber is increased larger than a pressure of the oil scraper chamber. CONSTITUTION:A communication path 17, which communicates with passages 15, 16 and an oil scraper chamber 9, is drilled in an intermediate member 6, here a one-way valve 18 is arranged.

Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To provide a motor-driven turbomachine to provide an increased life through reduction of a thrust load exerted on a bearing and perform safe operation for a long time. SOLUTION: The stator 4A of an electric motor 4 is disposed in a state to deviate a relative position to a rotor 4B to the opposite side to an impeller 2. By exciting the electric motor 4 by an inverter 15, an electromagnetic force in an axial direction is exerted on the rotor 4B in a manner to correct a deviation from the stator 4A. Namely, the rotor 4B is attracted to the opposite side to an impeller and by compressing gas through rotation of the impeller 2, an action is carried out in a direction in which a force exerted on the impeller 2 and pushing up a rotary body is offset by a differential pressure generated between a cascade surface (an upper surface) and its back (an under surface).  By selecting a deviation amount between the rotor 4B and the stator 4A such that a thrust load exerted on a rotary body through a differential pressure generated in the compressor work of the impeller 2 and a thrust load exerted on the rotor 4B are matched with each other, other thrust load than a load exerted on the bearings 6 and 7 by a spring 22 is reduced and an increased life is provided for a bearing.
