ッパーに関するものである。[Detailed description of the invention] This invention is a solid gas that is connected to the tip of a gas conveying duct of a device that produces spherical solidified slag from molten blast furnace slag, and that separates gas and granular slag and stores the granular slag. This invention relates to a separate type granular slag storage hopper.
本出願人はさきに溶融高炉滓から粒状固化源の製造装置

されるようになっている。As shown in Fig. 1, this device sends a slag flow 2' flowing down from a downflow gutter 3 provided at the bottom of a ladle 1 for storing molten blast furnace slag from a spray nozzle 4 disposed below the downflow gutter 3. By blowing the air jet, it becomes a spherical or nearly spherical particle slag 2a that is scattered and granulated in the wind cylinder 5 disposed in front of the wind cylinder 5, and the wind cylinder 5 is used as a conveying gas.
The particle slag 2a is cooled while flying by a mixed air flow of the air flow sucked from the open part 5a formed at the front end of the wind cylinder 5 and the above-mentioned air jet. The grain slag 2a collides with the plate 6 and falls, and is sucked into the conveying duct 7 in the direction of the arrow a through the discharge port 5' provided at the lower end of the collision plate 6, and the granule slag 2a sucked into the conveying duct is conveyed. The slag 2a is guided to the separator 9 while being cooled in the duct, and separated from the carrier gas in the separator 9. The slag 2a is appropriately collected through a cutting gate 10 provided at the bottom of the separator 9, and then transported. The gas is discharged into the atmosphere from the induction fan 8 through the induction pipe 11.
本考案の目的は上記同化滓製造装置において搬送ダクト

ある。The purpose of the present invention is to provide a separator that can efficiently and completely separate the granular slag conveyed from the transport duct together with the carrier gas in the above-mentioned assimilated slag production equipment, that is, a solid gas bone-release type granular slag storage device. It is intended to provide a hopper.
本考案による貯蔵ホッパーの詳細を図示の実施例につい
て説明する。The storage hopper according to the invention will now be described in detail with reference to the illustrated embodiment.
第２図は本考案による貯蔵用ホッパーの説明断面図であ
る。FIG. 2 is an explanatory cross-sectional view of a storage hopper according to the present invention.

突するように取替自在に取付けられている。In the figure, reference numeral 13 denotes a main body of a storage hopper, in which a curved ceiling member 14 made of cast steel or steel plate shown in FIG. It is replaceably installed so that all the slag discharged together with the carrier gas collides with each other.

れている。The remaining opening portion of the hopper body 13 that is not covered by the curved ceiling member 14 has one end connected to the curved ceiling member 14.
The other end is tightly covered by a cover 15 that is fixed to the upper opening edge 17 of the hopper body 13, and the reduced diameter top opening 19 of the cover 15 has a suction (not shown). An exhaust duct 16 communicating with the fan is connected.
本考案のホッパーは以上の如き構成であるから、搬送用

。Since the hopper of the present invention has the above-described configuration, the grain slag that has been transported through the transport duct 7 by the transport gas first collides with the curved ceiling member 14 at the receiving opening of the hopper main body 13, and Due to the inertia caused by this collision, most of the grain slag falls toward the bottom of the hopper body 13 and is stored therein.
他方搬送用気体は彎曲天井部材１４によって一旦は下向
きに変向せしめられた後に、排気ダクト１６を通じての
吸引ファンの吸引力により矢印で示す如くＵターンする
。On the other hand, the conveying gas is once deflected downward by the curved ceiling member 14, and then makes a U-turn as shown by the arrow due to the suction force of the suction fan through the exhaust duct 16.
その際搬送用気体によって搬送されつつある残余の粒滓
は排気ダクト１６に到達するまでに自重により沈降して
同様にホッパーに貯留される。At this time, the remaining grain slag being transported by the transporting gas settles under its own weight before reaching the exhaust duct 16 and is similarly stored in the hopper.
以上の如く本考案のホッパーによれば、搬送用気体から
の粒滓の分離が、彎曲天井部材への衝突による慣性力と
粒滓自体の自重による沈降力とによって行なわれるので
、極めて簡単な構造を以って固気体分離が効率的に実施
できるという実用的効果が奏される。As described above, according to the hopper of the present invention, the particle slag is separated from the conveying gas by the inertial force caused by collision with the curved ceiling member and the settling force due to the weight of the particle slag itself, so the structure is extremely simple. This brings about the practical effect that solid-gas separation can be carried out efficiently.
