Description

本発明は、例えば魚粕、パルプ、汚泥のような大量の水分を含んだ含水原料を効率良く脱水するためのスクリュープレスに関するものである。   The present invention relates to a screw press for efficiently dehydrating a water-containing raw material containing a large amount of water such as fish salmon, pulp and sludge.

従来のこの種のスクリュープレスにおいては、入口部から投入された含水原料が、濾過筒内においてスクリュー胴の回転により出口部の方向に搬送される過程で、体積が縮小するように圧搾され、水分は濾過筒の脱水孔から漏出し、脱水された原料は脱水ケーキとして出口部から排出される。   In this type of conventional screw press, the water-containing raw material introduced from the inlet portion is compressed so that the volume is reduced in the process of being conveyed in the direction of the outlet portion by the rotation of the screw cylinder in the filter cylinder. Leaks from the dewatering hole of the filter cylinder, and the dehydrated raw material is discharged from the outlet as a dehydrated cake.

しかし、このスクリュープレスの脱水効率には限界があり、大量の水分を含んだ原料については充分な脱水を行うことができない。   However, there is a limit to the dewatering efficiency of this screw press, and sufficient dewatering cannot be performed on a raw material containing a large amount of moisture.

そのために、別途に脱水装置を設けて予備脱水を行うこともあるが、プロセスが大規模となり、原料の運搬機構を別途に設けなければならない。   For this purpose, a separate dehydration apparatus may be provided for preliminary dehydration, but the process becomes large and a raw material transport mechanism must be provided separately.

本発明の目的は、上述の課題を解決し、スクリュープレス本体に予備濃縮手段を簡便に付設して、含水原料を更に効率良く脱水してケーキとして排出し得るスクリュープレスを提供することにある。   An object of the present invention is to solve the above-mentioned problems, and to provide a screw press capable of simply dehydrating a water-containing raw material and discharging it as a cake by simply attaching a pre-concentration means to the screw press main body.

上記目的を達成するための請求項１に係る本発明は、駆動手段により回転するスクリュー胴と、該スクリュー胴の外周に螺旋状に設けたスクリュー羽根と、該スクリュー羽根を囲む略円筒状の濾過筒とから成り、前記濾過筒の両端部に入口部と出口部を設け、前記スクリュー胴と前記スクリュー羽根と前記濾過筒によって囲んだ空間部を前記入口部から前記出口部に向けて減少させ、前記入口部から投入した含水原料を圧搾脱水して前記出口部から脱水ケーキとして排出するスクリュープレスにおいて、前記入口部に前記含水原料に対する予備濃縮手段を構設したことを特徴とするスクリュープレスである。   In order to achieve the above object, the present invention according to claim 1 includes a screw cylinder rotated by a driving means, screw blades spirally provided on the outer periphery of the screw cylinder, and a substantially cylindrical filtration surrounding the screw blades. An inlet portion and an outlet portion at both ends of the filter cylinder, and the space surrounded by the screw barrel, the screw blade, and the filter cylinder is reduced from the inlet portion toward the outlet portion, In the screw press that squeezes and dehydrates the water-containing raw material charged from the inlet portion and discharges it as a dehydrated cake from the outlet portion, a pre-concentration means for the water-containing raw material is provided at the inlet portion. .

また、請求項２に係る本発明は、前記予備濃縮手段はスクリューにより含水原料を押し込み、周囲の濾過スクリーンにより排水を行うことを特徴とする請求項１に記載のスクリュープレスである。   Moreover, the present invention according to claim 2 is the screw press according to claim 1, wherein the preconcentration means pushes the water-containing raw material with a screw and drains it with a surrounding filter screen.

更に、請求項３に係る本発明は、前記予備濃縮手段はスクリュー軸を鉛直方向に向けたことを特徴とする請求項２に記載のスクリュープレスである。   Furthermore, the present invention according to claim 3 is the screw press according to claim 2, wherein the pre-concentration means has a screw shaft oriented in a vertical direction.

請求項４に係る本発明は、前記予備濃縮手段は前記入口部の筒状体内に設けたことを特徴とする請求項１に記載のスクリュープレスである。   The present invention according to claim 4 is the screw press according to claim 1, wherein the pre-concentration means is provided in a cylindrical body of the inlet portion.

本発明に係るスクリュープレスによれば、スクリュープレス本体で脱水する前処理として、スクリュープレス本体の入口部に設けた予備濃縮手段により或る程度の予備濃縮ができるので、全体として高度の脱水処理を行うことができる。   According to the screw press according to the present invention, as a pre-treatment for dehydration in the screw press main body, a certain degree of pre-concentration can be performed by the pre-concentration means provided at the inlet portion of the screw press main body. It can be carried out.

本発明を図示の実施の形態に基づいて詳細に説明する。
図１は実施例の縦断面図であり、左右の支持台１、２にはスクリュー胴３が軸受け４、５を介して回転自在に支持されている。スクリュー胴３は下流側に進むにつれて太くなるテーパ状ととされ、スクリュー胴３にスクリュー羽根６が等ピッチで螺旋状に巻回されている。 The present invention will be described in detail based on the illustrated embodiment.
FIG. 1 is a longitudinal sectional view of the embodiment. A screw barrel 3 is rotatably supported on left and right support bases 1 and 2 via bearings 4 and 5. The screw barrel 3 has a tapered shape that becomes thicker as it goes downstream, and screw blades 6 are wound around the screw barrel 3 in a spiral manner at an equal pitch.

スクリュー胴３の例えば左端側にはスプロケット７が取り付けられ、このスプロケット７は図示しない駆動モータにチェーンを介して連結されている。なお、スプロケット７を介さずに、駆動モータをスクリュー胴３に直結することもできる。   For example, a sprocket 7 is attached to the left end side of the screw body 3, and the sprocket 7 is connected to a drive motor (not shown) via a chain. The drive motor can be directly connected to the screw barrel 3 without the sprocket 7 being interposed.

スクリュー羽根６の外周は多数の脱水孔を有する円筒状の濾過筒８により包囲されており、この濾過筒８の上流側、下流側にはそれぞれ側板９、１０が設けられ、スクリュー胴３はこれらの側板９、１０を貫通している。濾過筒８には両端部に原料の入口部１１と出口部１２が設けられていると共に、多数の補強環１３により補強され、全体は基台１４上に固定されている。   The outer periphery of the screw blade 6 is surrounded by a cylindrical filter tube 8 having a number of dewatering holes. Side plates 9 and 10 are provided on the upstream side and the downstream side of the filter tube 8, respectively. The side plates 9 and 10 are penetrated. The filter tube 8 is provided with raw material inlet portions 11 and outlet portions 12 at both ends, and is reinforced by a number of reinforcing rings 13, and the whole is fixed on a base 14.

更に、入口部１１の上方には、基台１４に連なるフレーム２１を介して予備濃縮手段２２が設置されており、鉛直方向に配置されたスクリュー胴２３の周囲にスクリュー羽根２４が設けられており、スクリュー羽根２４の周囲には多数の孔が設けられたパンチングメタルなどから成る円筒状の濾過スクリーン２５が設けられている。なお、スクリュー胴２３の径は先端から末端まで同径とされ、スクリュー羽根２４は等ピッチに配置されている。   Further, a pre-concentration means 22 is installed above the inlet portion 11 via a frame 21 connected to the base 14, and screw blades 24 are provided around a screw body 23 arranged in the vertical direction. A cylindrical filtration screen 25 made of punching metal or the like provided with a large number of holes is provided around the screw blade 24. The diameter of the screw body 23 is the same from the tip to the end, and the screw blades 24 are arranged at an equal pitch.

フレーム２１にはモータ２６が固定され、ギアボックス２７を介してスクリュー胴２３を回転するようにされている。濾過スクリーン２５の上部には原料供給口２８が設けられ、濾過スクリーン２５の下部には皿状の水受部２９が設けられ、その一部に排水口３０が設けられている。   A motor 26 is fixed to the frame 21, and the screw cylinder 23 is rotated via a gear box 27. A raw material supply port 28 is provided at the top of the filtration screen 25, a dish-shaped water receiving portion 29 is provided at the bottom of the filtration screen 25, and a drainage port 30 is provided at a part thereof.

脱水時には、泥状の含水原料は予備濃縮手段２２の上方の供給口２８から投入されると、スクリュー羽根２４の回転と自重により下方に移動する過程で、相当量の水分が濾過スクリーン２５から外方に排出される。排出された水分は濾過スクリーン２５の外部を伝わって落下して水受部２９に集められ、排水口３０から排水される。   At the time of dehydration, when the muddy water-containing raw material is introduced from the supply port 28 above the pre-concentration means 22, a considerable amount of moisture is removed from the filter screen 25 in the process of moving downward by the rotation of the screw blade 24 and its own weight. It is discharged towards. The discharged moisture travels outside the filtration screen 25 and falls and is collected in the water receiving portion 29 and drained from the drain port 30.

このようにして或る程度の水分含有率に予備濃縮された原料は、予備濃縮手段２２の出口からスクリュープレス本体の入口部１１に投入されて濾過筒８内に入り、スクリュー胴３、スクリュー羽根６、濾過筒８に囲まれた空間部において、スクリュー胴３の回転に従って徐々に空間部内を出口部１２側に移動する。   The raw material preliminarily concentrated to a certain water content in this way is introduced into the inlet 11 of the screw press main body from the outlet of the preconcentrating means 22 and enters the filter cylinder 8, and the screw barrel 3 and screw blades. 6. In the space part surrounded by the filter cylinder 8, the inside of the space part gradually moves toward the outlet part 12 as the screw cylinder 3 rotates.

この過程で、空間部の体積は徐々に縮小されているために、原料は圧搾されて水分が分離され、分離した水分は濾過筒８の脱水孔から漏出し、出口部１２に到達した脱水された原料は脱水ケーキとして排出される。   In this process, since the volume of the space portion is gradually reduced, the raw material is squeezed to separate the moisture, and the separated moisture leaks from the dewatering hole of the filter tube 8 and is dehydrated after reaching the outlet portion 12. The raw material is discharged as a dehydrated cake.

なお変形例として、スクリュープレス本体の筒状の入口部１１の径を大きくかつ長くして、この入口部１１内に予備濃縮手段２２を配置することもできる。   As a modification, the diameter of the cylindrical inlet portion 11 of the screw press main body can be made larger and longer, and the preconcentration means 22 can be arranged in the inlet portion 11.
