Description

本発明は、鋳造後に鋳型からバラした鋳物砂塊を粉砕して鋳物砂と地金等の混入物とを分離する鋳物砂塊粉砕装置に関する。   The present invention relates to a foundry sand lump crusher for crushing a cast sand lump separated from a mold after casting to separate the foundry sand and contaminants such as bullion.

従来の鋳物砂塊粉砕装置としては、横向きで回転するドラム内に円筒状の粉砕篩分け体（以下トロメルという）を所定間隔をおいて取り付けたものが公知である。トロメルは、軸方向に所定間隔をおいた環状の枠体間に多数本の丸鋼を一定間隔おいて架設した構造で、ドラムを回転させて鋳物砂塊をトロメル内に投入すると、鋳物砂塊が丸鋼に引っ掛かって回転方向へ持ち上げられ、ある程度の高さまで持ち上げられると自重で落下して粉砕され、その粉砕された鋳物砂は丸鋼間の間隙からドラムに排出され、混入物をトロメル内に残して分離できるようにしている。   As a conventional molding sand lump crusher, a device in which a cylindrical crushing sieving body (hereinafter referred to as a tromel) is attached at a predetermined interval in a drum rotating in a horizontal direction is known. The tromel is a structure in which a large number of round steel bars are installed at regular intervals between annular frames that are spaced apart in the axial direction. Is caught in the round steel bar and lifted in the direction of rotation, and when it is lifted to a certain height, it falls by its own weight and is crushed.The crushed foundry sand is discharged from the gap between the round steel bars to the drum, and the contaminants are put into the tromel. So that it can be separated.

ところで、前記技術では、トロメルを長期間使用していると、高温の鋳物砂塊や混入物による衝撃及び熱で丸鋼が部分的に損耗することがある。しかし、従来のトロメルは各部が一体的に製作されていたから、損耗した丸鋼のみを部分交換することは不可能であり、トロメル全体を交換するか又は鋳物砂塊粉砕装置そのものを交換しなくてはならず、多額の交換費用と工事日数と人員を必要としていた。また、従来のトロメルは溶接で製作されていたから、溶接部分に歪みが発生することがあり、強度に悪影響を及ぼすことがあった。   By the way, in the said technique, when a tromel is used for a long period of time, a round steel may be partially worn out by the impact and heat by a high-temperature casting sand lump or a contaminant. However, since each part of the conventional tromel is manufactured integrally, it is impossible to replace only the worn round steel, and it is necessary to replace the entire tromel or the casting sand lump crusher itself. Rather, it required a large amount of replacement costs, construction days and personnel. Further, since the conventional tromel is manufactured by welding, distortion may occur in the welded portion, which may adversely affect the strength.

本実施例の鋳物砂塊粉砕装置は、図１に示すように、貫通した横向きの中空のドラム１０と、ドラム１０内にその内面と所定間隔をおいて取り付けた円筒状のトロメル２０と、ドラム１０とトロメル２０を横向きの状態で回転自在に設置する傾斜可能な基台３０と、ドラム１０を回転させるモーター４０と、粉砕した鋳物砂を回収するホッパー５０とで構成している。   As shown in FIG. 1, the casting sand lump crushing apparatus of the present embodiment includes a penetrating horizontal hollow drum 10, a cylindrical tromel 20 attached to the inner surface of the drum 10 at a predetermined interval, and a drum. 10 and the tromel 20 are configured by a tiltable base 30 that is rotatably installed in a sideways state, a motor 40 that rotates the drum 10, and a hopper 50 that collects crushed foundry sand.

ドラム１０は、一端を投入側とし、他端を排出側とした中空の構造である。基台３０は、中央部を支軸３１でシーソー可能に枢支し、ドラム１０の投入側の位置に昇降装置３２を設けている。モーター４０は、チェーン又は歯付きベルト或いは歯車を介してドラム１０を駆動し、ドラム１０の両側の外周面を支持ローラ４１で支持している。ホッパー５０は、側面を開口してドラム１０の排出側を回転可能に挿入し、回収した鋳物砂を排出する排出口５１を下部に設けている。   The drum 10 has a hollow structure in which one end is the input side and the other end is the discharge side. The base 30 is pivotally supported at the center by a support shaft 31 so as to be seesaw, and an elevating device 32 is provided at a position on the charging side of the drum 10. The motor 40 drives the drum 10 via a chain, a toothed belt, or a gear, and supports the outer peripheral surfaces on both sides of the drum 10 with support rollers 41. The hopper 50 has a discharge port 51 for opening the side surface thereof and rotatably inserting the discharge side of the drum 10 and discharging the recovered foundry sand.

トロメル２０は、図２〜４に示すように、５６体の粉砕スノコ２１と、粉砕スノコ２１を取り付けるための９体の枠体２２と、前後の枠体２２同士を連結するための８本の連結棒２３と、粉砕スノコ２１を枠体２２に螺着するための多数のボルト２４と、鋳物砂塊の投入口２５と、鋳物砂を送るための送り羽根２６とで構成している。   As shown in FIGS. 2 to 4, the tromel 20 includes 56 crushed slats 21, nine frame 22 for attaching the pulverized slats 21, and eight pieces for connecting the front and rear frame bodies 22 to each other. The connecting rod 23, a large number of bolts 24 for screwing the crushed slats 21 to the frame 22, a casting sand lump inlet 25, and a feed blade 26 for feeding the casting sand.

粉砕スノコ２１は、図５，６に示すように、トロメル２０の外周を８分割した寸法及び角度の断面円弧状の基板２１ａに１６本のスリット２１ｂを軸方向に所定間隔をおいて開口し、基板２１ａの内部空間側となる面に４本の丸鋼２１ｃを軸方向に溶着している。また、基板２１ａの端部にはボルト孔２１ｄを６箇所開口し、そのボルト孔２１ｄの内部空間側にボルト２４の頭部を保護する保護筒２１ｅを形成している。   As shown in FIGS. 5 and 6, the pulverized slats 21 have 16 slits 21 b opened at predetermined intervals in the axial direction on a substrate 21 a having an arc-shaped cross section having a size and an angle obtained by dividing the outer periphery of the tromel 20 into eight parts. Four round steels 21c are welded in the axial direction on the surface of the substrate 21a on the inner space side. Further, six bolt holes 21d are opened at the end of the substrate 21a, and a protective cylinder 21e for protecting the head of the bolt 24 is formed on the inner space side of the bolt hole 21d.

枠体２２は、トロメル２０の外径を有する環状で、粉砕スノコ２１の取り付け位置にボルト孔２２ａを螺刻している。この枠体２２を軸方向に所定間隔をおいて配置し、前後の枠体２２間に連結棒２３を架設して円筒状の骨格を形成し、これをドラム１０の内面に取り付けている。この枠体２２に前記の粉砕スノコ２１を円周方向及び軸方向に円筒が形成されるように複数隣接し、その粉砕スノコ２１を枠体２２に対して内部空間側からボルト２４で螺着している。   The frame body 22 has an annular shape having the outer diameter of the tromel 20, and is screwed with a bolt hole 22 a at the attachment position of the pulverized snowboard 21. The frame bodies 22 are arranged at predetermined intervals in the axial direction, and a connecting rod 23 is installed between the front and rear frame bodies 22 to form a cylindrical skeleton, which is attached to the inner surface of the drum 10. A plurality of the crushed slats 21 are adjacent to the frame body 22 so as to form a cylinder in the circumferential direction and the axial direction, and the crushed slats 21 are screwed to the frame body 22 with bolts 24 from the inner space side. ing.

本実施例では、昇降装置３２で基台３０を投入口２５が上向くように若干傾斜させてモーター４０を作動させ、その投入口２５に鋳型からバラした高温の鋳物砂塊を投入する。鋳物砂塊はドラム１０の回転と傾斜と送り羽根２６により奥へ搬送され、粉砕スノコ２１の丸鋼２１ｃに引っ掛かって回転方向へ持ち上げられる。鋳物砂塊はある程度の高さまで持ち上げられると自重で落下し、その衝撃で粉砕される。   In this embodiment, the base 30 is slightly tilted by the elevating device 32 so that the charging port 25 faces upward, the motor 40 is operated, and the hot casting sand lump separated from the mold is charged into the charging port 25. The cast sand lump is conveyed to the back by the rotation and inclination of the drum 10 and the feed blade 26, and is caught by the round steel 21c of the pulverized stool 21 and lifted in the rotation direction. When the sand lump is lifted to a certain height, it falls by its own weight and is crushed by the impact.

粉砕された鋳物砂はスリット２１ｂから排出されてドラム１０に落下し、混入物はトロメル２０内に残り、鋳物砂と混入物とが分離される。ドラム１０に落下した鋳物砂は内部空間を流通する空気と接触して冷却され、ドラム１０の回転と傾斜と送り羽根２６によって搬送されてホッパー５０に回収される。粉砕スノコ２１の保護筒２１ｅには鋳物砂が溜まり、その鋳物砂がボルト２４の頭部を被覆して保護し、ボルト２４の損傷を防止して耐久性を高める。   The crushed foundry sand is discharged from the slit 21b and falls onto the drum 10, and the contaminants remain in the tromel 20, so that the foundry sand and the contaminants are separated. The foundry sand that has fallen on the drum 10 is cooled in contact with the air flowing through the internal space, and is conveyed by the rotation and inclination of the drum 10 and the feed blades 26 and collected by the hopper 50. Foundry sand accumulates in the protective cylinder 21e of the pulverized slats 21, and the foundry sand covers and protects the head of the bolt 24, thereby preventing damage to the bolt 24 and enhancing durability.

ここで、トロメル２０を長期間使用していると、高温の鋳物砂塊や混入物による衝撃及び熱で丸鋼２１ｃが部分的に損耗することがある。この場合、図７に示すように、その損耗した丸鋼２１ｃを有する粉砕スノコ２１のみを６本のボルト２４を外して枠体２２から取り外し、別の新しい粉砕スノコ２１を枠体２２の前記取り外した部分に配置し、内部空間側からボルト２４で螺着する。   Here, when the tromel 20 is used for a long period of time, the round steel 21c may be partially worn by the impact and heat of the high-temperature casting sand lump or contaminants. In this case, as shown in FIG. 7, only the crushed slats 21 having the worn round steel 21 c are removed from the frame 22 by removing the six bolts 24, and another new crushed slats 21 are removed from the frame 22. And is screwed with a bolt 24 from the inner space side.

このように、本実施例によれば、損耗した箇所の粉砕スノコ２１のみを短時間に交換できるようになり、トロメル２０の修理に伴う費用が大幅に削減され、鋳物砂塊粉砕装置の使用可能期間を大幅に延長できるようになった。また、粉砕スノコ２１は枠体２２に溶着しないから、歪みの発生が防止され、トロメル２０の強度を維持できるようになった。   As described above, according to the present embodiment, it becomes possible to replace only the crushed slats 21 at the worn portions in a short time, and the cost for repairing the tromel 20 can be greatly reduced, and the casting sand lump crusher can be used. The period can be extended significantly. Further, since the pulverized slats 21 are not welded to the frame body 22, the occurrence of distortion is prevented and the strength of the tromel 20 can be maintained.

本発明の技術は、鋳造後に鋳型からバラした鋳物砂塊を粉砕して鋳物砂と地金等の混入物とを分離する用途に利用される。   The technology of the present invention is used for the purpose of separating a foundry sand lump from a mold after casting to separate the foundry sand and contaminants such as metal.
