この発明は砂の回収方法に関し、特にスパイラル分級機
に沈澱タンクを連通させることによって排水と共に流出
する微砂をも確実に回収できる砂の回収方法に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sand recovery method, and more particularly to a sand recovery method that can reliably recover fine sand that flows out with wastewater by communicating a sedimentation tank with a spiral classifier.
従来より使用されているスパイラル分級機による砂の回

とんど全部混入され排水と共に流出するために微砂の回
収は不可能であった。To recover sand using a conventional spiral classifier, raw materials and water were put into the spiral classifier, and large and medium-sized sand was classified by the stirring action of the spiral. Almost all of the fine sand, which is particulate and lightweight, is mixed in and flows out with the wastewater, making it impossible to recover the fine sand.
この発明の方法は上記の欠点を解決したもので、まずこ

内へ送り込まれてきた小粒子の微砂をスパイラル分級機
１へ押しもどす役割をしている。The fine sand sending device 7 includes a rotating gear 9 and a fine sand scraping protrusion 10.
It consists of a conveyor 11 with a sedimentation tank 5.
Its role is to push back the small particles of fine sand that have been sent into the spiral classifier 1.
該スパイラル分級機１と沈澱タンク５との間には微砂流
入に１２付仕切板１３が形成されている。Between the spiral classifier 1 and the settling tank 5, a partition plate 13 with 12 holes is formed for inflowing fine sand.

入の原料投入口Ａより投入し、且つ、水投入口Ｂより水
を供給しスパイラル分級機内で水洗い及び分級を行なう
。To explain in detail the method for recovering fine sand of the present invention, raw material mixed with fine sand is inputted from an input port A, water is supplied from a water input port B, and washing and classification are performed in a spiral classifier.
原料の内微砂や泥分はスパイラルの撹拌作用により上方
部へ浮上し、仕切板の上部よりオーバーフロー分が沈澱
タンク５内へと送出される。The fine sand and mud in the raw material float upwards due to the stirring action of the spiral, and the overflow is sent into the settling tank 5 from the upper part of the partition plate.
沈澱タンク５内では時間の経過と共に小粒子の微砂や泥
分は沈下し底に沈澱する。In the sedimentation tank 5, small particles of fine sand and mud settle over time and settle to the bottom.
沈澱した微砂はコンベアー１１に取り付けられた微砂掻
き突起１０によりスパイラル分級機１内へ送り込まれる
。The settled fine sand is fed into the spiral classifier 1 by a fine sand scraping protrusion 10 attached to a conveyor 11.
送り込まれた微砂はスパイラルの撹拌作用で再浮上して
も沈澱タンク５内で必ず沈澱するために外部に流出する
ことがない。Even if the fed fine sand resurfaces due to the agitation action of the spiral, it will always settle within the settling tank 5 and will not flow out to the outside.
この繰返し作用により沈澱タンク５からスパイラル分級
機に送り込まれる微砂の量が多くなり、微砂を多量に投
入した状態と同じになり微砂を回収することができる。Due to this repeated action, the amount of fine sand sent from the settling tank 5 to the spiral classifier increases, and the state is the same as that in which a large amount of fine sand is input, and the fine sand can be recovered.
他方、水及び泥分はそのオーバーフロー分が水流出口８
より外部へ流出される。On the other hand, the overflow of water and mud flows through the water outlet 8.
more leaked to the outside.
押しもどされた微砂は犬・中粒子の砂と共に洗浄された
砂として開口部Ｃより外部へ送出される。The pushed back fine sand is sent out from the opening C as washed sand together with sand of small to medium particles.
また第２図の実施例は微砂掻き突起１０付コンベアー１
１の替わりに微砂送出用スクリューコンベアー１４を形
成し、該スクリューコンベアーの回転により微砂をスパ
イラル分級機１へ押し戻すものである。The embodiment shown in Fig. 2 is a conveyor 1 with fine sand scraping protrusions 10.
1 is replaced by a screw conveyor 14 for sending out fine sand, and the rotation of the screw conveyor pushes the fine sand back to the spiral classifier 1.
また実施例ではスパイラル分級機１と沈澱タンク５の間
に仕切板１３を設けて、この仕切板１３をオーバーフロ
ーした微砂を含有した排水を沈澱タンク５に送り出した
が、スパイラル分級機１内の微砂を含有した排水を投入
装置などによって自動的に送り出すことも可能である。In addition, in the embodiment, a partition plate 13 was provided between the spiral classifier 1 and the settling tank 5, and the waste water containing fine sand that overflowed the partition plate 13 was sent to the settling tank 5. It is also possible to automatically send out wastewater containing fine sand using a feeding device or the like.
この発明の方法は特に沈澱タンクを設けたことにより撹
拌作用をそのままにし掻き揚げ能力を低下させずに微砂
を確実に回収できるものできわめて能率的で経済的なも
のである。In particular, the method of the present invention is extremely efficient and economical because it is equipped with a sedimentation tank so that the stirring action remains unchanged and fine sand can be reliably recovered without reducing the raking ability.
更に、微砂の回収方法がその自重に基づいているので微
砂の重量の相違によりその沈澱箇所が異なり、その原理
を利用して沈澱タンクの幅と長さを決定し、砂と泥分を
分級することができる。Furthermore, since the collection method of fine sand is based on its own weight, the settling location differs depending on the weight of fine sand, and this principle is used to determine the width and length of the settling tank to separate sand and mud. Can be classified.
沈澱タンクに微砂掻き突起付コンベアーを内蔵したので
自動的且つ確実に沈澱タンクに沈澱した微砂を再びスパ
イラル分級機内へ送り込むことができる。Since the sedimentation tank has a built-in conveyor with fine sand scraping protrusions, the fine sand settled in the sedimentation tank can be automatically and reliably fed into the spiral classifier.
この動作の繰返し作用により沈澱タンクからスパイラル
分級機に送り込まれる微砂の量が多くなり、微砂を多量
に投入した状態と同じになり微砂を回収することができ
る。By repeating this operation, the amount of fine sand sent from the settling tank to the spiral classifier increases, and the state is the same as that of a large amount of fine sand being input, so that fine sand can be recovered.
