Description
【0001】[0001]
この考案は、電動起振機によって篩網に振動を与える振動ふるい機に関するも のである。 The present invention relates to a vibrating sieving machine that applies vibration to a screen by an electric exciter.
【0002】[0002]
振動発生装置に結合されて強制的に振動が与えられる振動台上に、下部篩分室 とその上方に位置する上部篩分室とを設け、両篩分室の境界に篩網を設けた振動 ふるい機が知られている。 通常、篩網は、下部篩分室壁の上端に設けた下部フランジと、上部篩分室壁の 下端に設けた上部フランジの間に挟持される。 A vibrating and sieving machine, in which a lower sieve compartment and an upper sieve compartment located above it are installed on a vibrating table that is connected to a vibration generator and is forcibly given a vibration, and a mesh screen is provided at the boundary of both sieve compartments Are known. Usually, the sieve mesh is sandwiched between a lower flange provided at the upper end of the lower sieving chamber wall and an upper flange provided at the lower end of the upper sieving chamber wall.
【0003】 図2は上述した篩網の挟持構造の1例を示し、下部篩分室51の室壁52の上 端に溶接した下部フランジ53は上面に環状V字溝54を有し、上部篩分室55 の室壁56の下端に溶接した上部フランジ57は下面にV字形環状突条58を有 する。両フランジ53、57間に篩網59の周縁部分を挟み、多数のボルト60 及びナット61により両フランジ53、57を締付けると、篩網59は環状突条 58によって環状V字溝54内に押込まれ、これによって篩網59が緊張状態で 張られる。FIG. 2 shows an example of a sandwiching structure of the above-mentioned sieve mesh. The lower flange 53 welded to the upper end of the chamber wall 52 of the lower sieve separating chamber 51 has an annular V-shaped groove 54 on the upper surface, and the upper sieve is The upper flange 57 welded to the lower end of the chamber wall 56 of the compartment 55 has a V-shaped annular protrusion 58 on the lower surface. When the peripheral edge portion of the sieve net 59 is sandwiched between both flanges 53 and 57 and both flanges 53 and 57 are tightened by a large number of bolts 60 and nuts 61, the sieve net 59 is pushed into the annular V-shaped groove 54 by the annular protrusion 58. Rarely, this causes the screen 59 to be tensioned.
【0004】[0004]
図2に示した篩網の取付構造では、篩網の交換に際して多数のボルト・ナット を操作しなければならないため、分解掃除や、目の寸法が異なる篩網と交換した い場合または、破損した篩網を新なものと交換する場合に極めて面倒であった。 この考案は、このような分解、篩網の交換を簡便に行い得るようにしたものであ る。 In the screen mesh mounting structure shown in Fig. 2, a large number of bolts and nuts must be manipulated when replacing the screen screen, so it is necessary to disassemble and clean it, or to replace it with a screen screen with different eye sizes, or if it is damaged. It was extremely troublesome to replace the sieve screen with a new one. The present invention makes it possible to easily perform such disassembly and replacement of the sieve screen.
【0005】[0005]
【課題を解決するための手段】 この考案による振動ふるい機は、下部篩分室壁の上端と上部篩分室壁の下端と にそれぞれ外方へ張出したフランジが設けられ、周縁に補強枠を有する篩網は上 記両フランジの間に挟持されている。両フランジは、互に対向する面の内側寄り に同じ方向に傾斜した傾斜面を有し、この傾斜面の外側に篩網の補強枠を受入れ るポケットを有している。[Means for Solving the Problems] A vibrating sieving machine according to the present invention is a sieve having outwardly extending flanges at the upper end of the lower sieving chamber wall and the lower end of the upper sieving chamber wall, and having a reinforcing frame at the periphery. The net is sandwiched between the above flanges. Each of the flanges has an inclined surface inclined in the same direction toward the inner side of the surfaces facing each other, and a pocket for receiving the reinforcing frame of the sieve mesh on the outside of the inclined surface.
【0006】 上方に位置するフランジの上面には下向傾斜したテーパー面が、また下方に位 置するフランジの下面には上向傾斜したテーパー面がそれぞれ形成されている。 これらテーパー面には、内側に向って開口したV字形断面の締付環の開口縁が 当接している。この締付環は一部で切断されており、切断端の双方の間に締付螺 子を有している。A tapered surface inclined downward is formed on the upper surface of the flange located above, and a tapered surface inclined upward is formed on the lower surface of the flange located below. An opening edge of a tightening ring having a V-shaped cross section, which opens inward, is in contact with these tapered surfaces. The fastening ring is partially cut and has a fastening screw between both cutting ends.
【0007】[0007]
2個のフランジの間に篩網を挟み、双方のフランジに跨って締付環を嵌め、締 付螺子を緊締すると、締付環の径が縮小してその開口縁がフランジのテーパー面 に深く嵌まり込み、これにより2個のフランジは互に挟圧される。その結果、篩 網は、補強枠を両フランジ間のポケットに保持された状態で、その内側部分が両 フランジの傾斜面によって伸張され、全体が緊張した状態になる。 Insert a sieve mesh between two flanges, fit a tightening ring across both flanges, and tighten the tightening screw. The diameter of the tightening ring decreases and its opening edge becomes deeper in the tapered surface of the flange. The two flanges are engaged with each other, so that the two flanges are pressed against each other. As a result, with the reinforcing frame being held in the pocket between both flanges, the inner part of the screen is stretched by the inclined surfaces of both flanges, and the entire screen becomes tense.
【0008】 以上のように、締付環の螺子の操作だけで両フランジを締付け得るために、そ の操作は多数のボルト・ナットを緊締する従来装置に較べて遙かに簡便になり、 掃除のための分解組立てや、目の寸法を異にする篩網との交換も随時行うことが できる。使用中に篩網が弛緩した場合は締付環の螺子を増し締めして、張力を回 復することができる。As described above, since both flanges can be tightened only by operating the screw of the tightening ring, the operation is much simpler than the conventional device that tightens a large number of bolts and nuts, and cleaning is easier. Can be disassembled and assembled, or replaced with a sieve screen having different mesh sizes. If the sieve screen becomes loose during use, the screw of the tightening ring can be tightened to recover the tension.
