Description
【０００１】[0001]
本考案は、し渣や塵芥などの含水固形物を連続的に圧搾脱水するスクリュー式 脱水機に関する。 The present invention relates to a screw type dehydrator for continuously squeezing and dehydrating water-containing solid matter such as residue and dust.
【０００２】[0002]
従来よりスクリュープレス式脱水機は汚泥の脱水に使用されており、その構造 は図２に示すようなものである。汚泥ホッパー１０の供給口１１と、脱水ケーキ 排出口１２との間に設けた円筒ろ材の外筒１３と外周にスクリュー羽根１４を有 するスクリュー軸１５とからなり、しかも外筒１３、スクリュー軸１５及びスク リュー羽根１４とで形成される空間容積を漸次縮小して、投入された汚泥をスク リュー軸１５の回転によって軸方向、即ち脱水ケーキ排出口１２方向に押し出し て圧搾し、汚泥より搾り出されたろ液を円筒ろ材の外筒１３より排出させ、脱水 ケーキを脱水ケーキ排出口１２より取り出すような構造、機能を有している。 Conventionally, a screw press type dehydrator has been used for dehydrating sludge, and its structure is as shown in FIG. The sludge hopper 10 comprises a cylindrical filter medium outer cylinder 13 provided between a supply port 11 and a dehydrated cake discharge port 12, and a screw shaft 15 having screw blades 14 on the outer periphery. The volume of space formed by the screw blades 14 and the screw blades 14 is gradually reduced, and the sludge that has been input is squeezed by being pushed out by the rotation of the screw shaft 15 in the axial direction, that is, toward the dehydrated cake discharge port 12 and squeezed. It has a structure and function of discharging the filtrate thus obtained from the outer cylinder 13 of the cylindrical filter medium and taking out the dehydrated cake from the dehydrated cake discharge port 12.

しかし、上記した従来のスクリュープレス式脱水機をし渣や塵芥などの含水固 形物を脱水することに適用しようとしたら、次のような問題点があることが判明 した。即ち、汚泥に比してし渣や塵芥はスクリューによる搬送の抵抗が大きく、 排出口側に僅かの障害物があっても、たちまち閉塞してしまうということである 。 本考案は上記欠点を解消して、し渣や塵芥をも連続的に閉塞することなしに脱水 し得るスクリュープレス式脱水機を提供することを目的とする。 However, when it was attempted to apply the above-mentioned conventional screw press type dehydrator to dehydration of water-containing solid matter such as residue and dust, it was found that the following problems would occur. That is, compared to sludge, the residue and dust have a higher resistance to be conveyed by the screw, and even if there is a slight obstacle on the outlet side, it will be blocked immediately. It is an object of the present invention to solve the above-mentioned drawbacks and to provide a screw press type dehydrator capable of dehydrating residue and dust without continuously blocking them.

本考案は周面に多数の水抜き穴を有する外筒と、外周にスクリュー羽根を有す る回転自在な軸を備え、脱水対象物の進行方向に向かって外筒と軸とスクリュー 羽根とで区画される容積を減少するスクリュープレス式脱水機において、 外筒とスクリュー羽根とは、前記進行方向に向かって円錐形に縮径しており、ス クリュー羽根は脱水対象物の供給側でのみ軸支されており、脱水対象物の排出口 は前記外筒の延長上にあることを特徴とするものである。 The present invention is equipped with an outer cylinder having a large number of water drain holes on its peripheral surface and a rotatable shaft having screw blades on the outer circumference. In a screw press type dewatering machine that reduces the partitioned volume, the outer cylinder and the screw blade are conically reduced in diameter in the direction of travel, and the screw blade is a shaft only on the supply side of the object to be dehydrated. The discharge port for the dehydration target is provided on the extension of the outer cylinder.

本考案の実施例を図面に基づいて説明する。 図１は本考案の実施例の断面図である。図中１は外筒で、円筒部１−１とテーパ 部１−２とからなり、外筒１の後端部には供給口２を接続し、前端部には排出口 ３を直線的に連結する。そして外筒１はステンレス鋼のパンチングメタルで形成 する。外筒１内にはスクリュー４を回転自在に配設する。スクリュー４はスクリ ュー軸５の外周にスクリュー羽根６を固説したものであり、スクリュー羽根６の 外周部は前記外筒１のテーパ部１−２と同一のテーパとなるように形成する。更 にスクリュー軸５の後端部側は軸受７で軸支し、且つ電動機８に連結する。スク リュー軸５の先端部は円錐形に形成してあり、この先端部は軸受で軸支はしない 。 そして外筒１及びスクリュー４は排出口３が上側になるように傾斜して設置する 。 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of an embodiment of the present invention. In the figure, 1 is an outer cylinder, which is composed of a cylindrical portion 1-1 and a tapered portion 1-2. A supply port 2 is connected to the rear end of the outer cylinder 1 and a discharge port 3 is linearly connected to the front end. Link. The outer cylinder 1 is made of stainless steel punching metal. A screw 4 is rotatably arranged in the outer cylinder 1. The screw 4 is a screw blade 6 fixed on the outer periphery of the screw shaft 5, and the outer peripheral portion of the screw blade 6 is formed to have the same taper as the taper portion 1-2 of the outer cylinder 1. Further, the rear end side of the screw shaft 5 is pivotally supported by a bearing 7 and is connected to the electric motor 8. The tip of the screw shaft 5 is formed in a conical shape, and this tip is a bearing and does not support the shaft. Then, the outer cylinder 1 and the screw 4 are installed so as to be inclined so that the discharge port 3 is on the upper side.
【０００６】 次に上記構成の作用について説明する。水とし渣の混合物は供給口から外筒１ 内へ供給する。この部分ではし渣は圧縮されずにスクリュー４によって搬送され るのみであるが、ここでは水は重力によりパンチングメタルの穴から外部へ排出 される。し渣がスクリュー４の先端部方向へ搬送されるに従い、スクリュー羽根 ６と外筒１とスクリュー軸５とで形成される空間の容積が小さくなるから、し渣 は圧縮されるようになり、ここで圧搾脱水が行われる。搾り出されたろ液はパン チングメタルの穴から外部へ排出される。そして外筒１の前端部から排出口３へ 排出されるのである。ここで、スクリュー軸５の先端部は円錐形をしており、し かも軸受等の障害物が無いため、圧搾されたし渣はスムーズに排出口３へ押し出 される。 又、外筒１とスクリュー４とは排出口３を上方にして傾斜して設置されているた め、特に重力による脱水機でのろ液の排出が速やかに行える。Next, the operation of the above configuration will be described. The mixture of water and residue is supplied into the outer cylinder 1 through the supply port. In this part, the residue is not compressed and is only conveyed by the screw 4, but here, water is discharged to the outside from the hole of the punching metal by gravity. As the screen residue is conveyed toward the tip of the screw 4, the volume of the space formed by the screw blade 6, the outer cylinder 1, and the screw shaft 5 becomes smaller, so that the screen residue becomes compressed. Pressed and dehydrated in. The squeezed filtrate is discharged to the outside through the holes in the punching metal. Then, it is discharged from the front end portion of the outer cylinder 1 to the discharge port 3. Here, since the tip end of the screw shaft 5 has a conical shape and there are no obstacles such as bearings, the pressed residue is smoothly pushed out to the discharge port 3. Further, since the outer cylinder 1 and the screw 4 are installed so as to be inclined with the discharge port 3 facing upward, the drainage of the filtrate can be quickly carried out especially by the dehydrator by gravity.

本考案は上記構成としたから、圧搾脱水されたし渣が閉塞を起こすことなく、 スムーズに排出できて実用的価値が大きい。 Since the present invention has the above-mentioned configuration, the pressed and dehydrated residue can be smoothly discharged without causing blockage, which is of great practical value.
