Description
【発明の詳細な説明】 ヒ１１ 本発明は木材のチップの洗浄に関する。[Detailed description of the invention] Hi11 The present invention relates to cleaning wood chips.
バルブの製造は通常、小片いわゆるチップにされた木材から行われている。これ らのチップには砂利、金属部分等の重量のある不純物（スクラップ）も付着して いる。これらの不純物は、チップが化学的に又は機械的にバルブに離解される前 に除去されねばならない、この除去作業は異なる方法で設計され得るいわゆるチ ップ洗浄機で実施される。The manufacture of valves is usually carried out from small pieces of so-called chipped wood. this These chips also contain heavy impurities (scrap) such as gravel and metal parts. There is. These impurities are removed before the chips are chemically or mechanically disintegrated into valves. This removal operation can be designed in different ways using so-called chips. It is carried out in a top washer.
チップの洗浄は通常２段階で実施されている。第１段階は容器内の重量のある不 純物を除去することを含み、この段階ではチップ及び水がブレードを伺えたロー タにより撹拌され、それにより不純物が底に沈む。その後、砂及びより微細な不 純物がスクリュウシラフナで除去される。これらの段階の間で、チップがタンク に収集され且つこのタンクから第２段階のためにポンプにより供給される。Chip cleaning is typically performed in two stages. The first step is to remove heavy objects inside the container. This step involves removing impurities, and this step involves removing chips and water from the blade. The mixture is stirred by a filter, which causes impurities to settle to the bottom. Then sand and finer particles The pure substance is removed by screw Shirafuna. Between these stages, the chip and from this tank is pumped for the second stage.
この従来の装置の場き、分離されるべき粒子は分離区域に移動させられずにチッ プと共に撹拌されるので、不純物の寸法が小さく且つ重量が軽ければ分離は不確 実となり、このことが欠点となる。In this conventional device, the particles to be separated are not moved to the separation area but are Since the impurities are stirred together with the liquid, if the size and weight of the impurities are small, separation may be uncertain. This becomes a drawback.
本発明は前述した問題の解決方法を提供する。チップ及び水用の螺旋状シュート を備えたタンクを使用すれば、不純物は比較的長い沈降路に沿って分離され且つ 同時に遠心力の作用を受け得る６更にはチップ及び水は連続的に放出されるが、 それと同時に不純物が濃縮され、それにより不純物の分離が容易になる。The present invention provides a solution to the problems mentioned above. Spiral chute for chips and water When using a tank with 6 Furthermore, chips and water are continuously released, which can be simultaneously affected by centrifugal force. At the same time, impurities are concentrated, which facilitates their separation.
本発明は、第１の分離段階及び従来の配置のポンプタンクの代わりに、後続のシ ラフナに直接接続され得る装置が使用され得ることを包含している。The present invention provides a first separation stage and a subsequent system instead of a conventional arrangement of pump tanks. It is contemplated that devices that can be connected directly to the roughness can be used.
後述する請求の範囲により、本発明の特徴は明白となる。The features of the invention will become apparent from the following claims.
これから添付図面を参照して本発明をより詳細に説明する。The invention will now be described in more detail with reference to the accompanying drawings.
第１図は本発明の装置の断面図である。FIG. 1 is a cross-sectional view of the device of the invention.
第２図は第１図に示す如き同一装置のＩ Ｉ−Ｉ Ｉでの断面図である。FIG. 2 is a cross-sectional view of the same device as shown in FIG. 1, taken along III--II.
本発明の実施例は円筒形タンク１を備え、その寸法は勿論所望の容量に依存して いる。タンクの直径は例えば１゜５〜３ｍであり得る。タンクはその内部に、タ ンクの壁の周りに１回転を僅かに越えて螺旋状に伸びているシュート２を備えて いる。申し分のない分離効果に達するために、タンク内のシュート２は少なくと も半回転に相当する長さがなければならない。シュートは好ましくは少なくとも １回転に相当する長さがなければならない。チップ及び水用の入り口３は、タン ク１上方で、シュート２の上方端部に配置されている。シュートの範囲は外側が タンクの壁により規定され、内側が縁部４により規定されている。縁部の高さは シューＩ・に沿って下方で低くなっている。シュートの底部はタンクの壁に向か って外側に傾斜されている。この傾斜はシュートに沿って増している。シュート は最初の方が急であり得る。シュートの最初の部分、好ましくは４分の１の部分 では、シュートは底部に凹凸又は段も備え得るが、後続部分は平滑でなければな らない。An embodiment of the invention comprises a cylindrical tank 1, the dimensions of which of course depend on the desired capacity. There is. The diameter of the tank can be, for example, 1.5 to 3 m. The tank has a tank inside it. The chute 2 extends spirally around the wall of the tank by slightly more than one revolution. There is. In order to reach a satisfactory separation effect, chute 2 in the tank should be at least must also have a length equivalent to half a revolution. The shoot preferably has at least It must have a length equivalent to one revolution. Inlet 3 for chips and water The chute 2 is disposed above the chute 1 and at the upper end of the chute 2. Shoot range is outside It is defined by the walls of the tank and on the inside by the edge 4. The height of the edge is It becomes lower and lower along shoe I. The bottom of the chute should face the wall of the tank. It is slanted outward. This slope increases along the chute. shoot may be steeper at the beginning. The first part of the shoot, preferably the quarter part In this case, the chute may also have irregularities or steps at the bottom, but the trailing part must be smooth. No.
タンクの壁に隣接するシュートの最終部分には、スクラップ用出口５が配置され ている。このスクラップ用出口は好ましくは間隔を置いて放出するように設計さ れ、即ち交互に開く２つのバルブを備えている。スクラップ用出口を通じて向流 を生じるように、給水管６がスクラップ用出口５に接続されている。In the final part of the chute adjacent to the tank wall a scrap outlet 5 is arranged. ing. This scrap outlet is preferably designed to discharge at intervals. In other words, it has two valves that open alternately. Countercurrent flow through the scrap outlet A water supply pipe 6 is connected to the scrap outlet 5 so as to produce the following.
タンク１の底部は、洗浄されたチップ用の中央山ロアに向けて下方に傾斜するよ うに円錐形状である。出ロアの周りには場合によっては１つ以上の付加的な環状 スクラップ用トラップ８が配置され得る。これらのトラップに関連して、開口部 が手動による排出のために配置され得る。The bottom of tank 1 slopes downward toward the central mountain lower for cleaned chips. It has a conical shape. Possibly one or more additional rings around the exit lower. A scrap trap 8 may be arranged. In connection with these traps, the opening may be arranged for manual evacuation.
洗浄されるべきチップは、水と共に入り口３を通じてシュート２内に供給され且 つシュート内を下降する。重量のある物質及び粒子は沈降によりシュート底部で 収集される。The chips to be cleaned are fed into the chute 2 through the inlet 3 together with water and descend inside the chute. Heavy substances and particles are deposited at the bottom of the chute due to sedimentation. collected.
遠心力の作用により、またシュートの底部はタンクの壁に向かって外側に傾斜し ているので、スクラップの分離は増す。シュートの最初の部分は底部に凹凸があ り且つ傾斜がより急なので、シュートのこの部分ではスクラップの除去が促進さ れているが、シュートの後続部分では沈降が所望されている。Due to the action of centrifugal force, the bottom of the chute also slopes outward towards the tank wall. scrap separation increases. The first part of the chute has an uneven bottom. Scrap removal is facilitated in this part of the chute due to its lower profile and steeper slope. However, sedimentation is desired in the trailing portion of the shoot.
不純物がシュートの底部及びタンクの壁に向かって外側に向けられると同時に、 縁部４では、チップ及び水が表面から溢れる。この縁部の高さは連続的に低減さ れて、チップ及び水の流入量の３０〜５０％だけがシュートの最終部分に残るよ うに寸法決定されるべきである。タンクの壁に隣接するシューＩ・底部で収集さ れた不純物は、スクラップ用出口５を通じて除去される。管６を通じての向流は ０゜１〜０．２ｍ／秒とすべきである。スクラップのないチップ及び水は出ロア を通じて流出され、且つポンプ９を介して後続の処理段階、通常濃縮段階に搬送 される。At the same time the impurities are directed outward towards the bottom of the chute and the walls of the tank. At the edge 4, chips and water overflow from the surface. The height of this edge is continuously reduced. so that only 30-50% of the inflow of chips and water remains in the final part of the chute. should be sized accordingly. Collected at the bottom of the shoe I adjacent to the wall of the tank. The impurities removed are removed through the scrap outlet 5. The countercurrent flow through tube 6 is It should be 0°1-0.2 m/sec. Scrap-free chip and water outlet and conveyed via pump 9 to a subsequent processing stage, usually a concentration stage. be done.
中央出口の周りに配置され得る付加的なスクラップ用トラップ８は、例外的な場 合に生じ得る過剰なスクラップ荷重でも安全である。このような荷重は例えば、 チップパケットの底部スクラッピング用装置を使用してチップがチップ水準から 取られるときに生じ得る。An additional scrap trap 8, which can be arranged around the central outlet, can be used in exceptional cases. It is safe even with excessive scrap loads that may occur in some cases. Such loads are, for example, Remove the chips from the chip level using a device for scraping the bottom of the chip packet. It can occur when taken.
本発明は勿論図示した実施例に制限されることはなく、本発明の主旨の範囲内で 変更され得る。The invention is of course not limited to the embodiments shown, but within the scope of the invention. subject to change.
