Description
本発明は、例えば、鉄鋼スラグのフォーミング現象を鎮静化する鎮静剤製造設備に係るものである。 The present invention relates to, for example, a calming agent manufacturing facility that calms the foaming phenomenon of steel slag.
従来、例えば、古紙の再生過程で生ずる製紙スラッジ（製紙屑）の成形固化物を鉄鋼スラグのフォーミング現象（泡立ち現象）を鎮静化する鎮静剤として用いることが知られており、一方、成形固化装置として、バレル内の産業廃棄物をスクリュー羽根の歯合空間で強制的に混練圧縮移送し、ダイスプレートのノズル孔より産業廃棄物の成形固化物を排出する構造のものが知られている。 For example, it has been known to use a molded solidified product of paper sludge (paper waste) generated during the recycling process of waste paper as a calming agent to calm the foaming phenomenon of steel slag. On the other hand, a molding and solidification device is known that has a structure in which industrial waste in a barrel is forcibly kneaded, compressed, and transported in the meshing space of the screw blades, and the molded and solidified product of industrial waste is discharged from the nozzle holes of the die plate.
そして、上記製紙スラッジを上記成形固化装置に適用するに際し、上記製紙スラッジは６０％～８０％の程度の高い含水率を有しているため、製紙スラッジの成形固化に支障を来すおそれがあり、このため、各種の乾燥手段等を用いて、予め、上記バレルに投入される製紙スラッジの含水率を２５％～３５％程度に調整する必要がある。 When the paper sludge is applied to the molding and solidification device, the paper sludge has a high moisture content of about 60% to 80%, which may hinder the molding and solidification of the paper sludge. For this reason, it is necessary to use various drying means, etc. to adjust the moisture content of the paper sludge before it is put into the barrel to about 25% to 35%.
しかしながら、上記従来構造を適用する場合、バレルに投入される製紙スラッジを乾燥し、製紙スラッジの含水率を予め２５％～３５％程度に調整してはおくものの、バレル内での製紙スラッジの混練圧縮移送に伴う摩擦熱により製紙スラッジの含水率が２５％以下となることがあり、製紙スラッジの含水率が２５％以下になると、製紙スラッジにより上記ダイスプレートのノズル孔の詰まり現象が生じ、ノズル孔の詰まりにより製紙スラッジの成形固化物の排出が困難となることがあるという不都合を有している。 However, when applying the above conventional structure, although the paper sludge fed into the barrel is dried and the moisture content of the paper sludge is adjusted in advance to about 25% to 35%, the moisture content of the paper sludge may fall below 25% due to frictional heat caused by the kneading, compression and transport of the paper sludge inside the barrel. When the moisture content of the paper sludge falls below 25%, the paper sludge may clog the nozzle holes of the die plate, and the clogging of the nozzle holes may make it difficult to discharge the molded solidified paper sludge.

この場合、図１の如く、上記製紙スラッジＰを上記定量供給部Ｆに投入する積み込み機械として、ホイールローダからなる建設機械Ｎが用いられ、又、上記定量供給部Ｆにあっては、図２の如く、上記建設機械Ｎからの製紙スラッジＰを貯留するための貯留ホッパーＦ１及び貯留ホッパーＦ１内の製紙スラッジＰを定量給送する給送機構Ｆ２を備えてなり、この場合、上記給送機構Ｆ２は、図２、図３の如く、貯留ホッパーＦ１を備えた給送機体Ｆ３に二個のスクリューＦ４・Ｆ４を回転自在に並列配置し、二個のスクリューＦ４・Ｆ４をモータＦ５により回転させ、上記バレル１内の製紙スラッジＰの量の低下信号を受けて二個のスクリューＦ４・Ｆ４が回転し、スクリューＦ４・Ｆ４の回転により貯留ホッパーＦ１内に貯留された製紙スラッジＰを順次定量給送して落下口Ｆ６から落下させるように構成している。 In this case, as shown in FIG. 1, a construction machine N consisting of a wheel loader is used as a loading machine for dumping the papermaking sludge P into the quantitative supply section F, and the quantitative supply section F is equipped with a storage hopper F1 for storing the papermaking sludge P from the construction machine N and a feed mechanism F2 for feeding a quantitative amount of the papermaking sludge P in the storage hopper F1 , as shown in FIG . 2. In this case, the feed mechanism F2 , as shown in FIG. 2 and FIG. 3, has two screws F4 and F4 rotatably arranged in parallel on a feeder body F3 equipped with a storage hopper F1, and the two screws F4 and F4 are rotated by a motor F5 . The two screws F4 and F4 are rotated upon receiving a signal indicating a decrease in the amount of papermaking sludge P in the barrel 1 , and the rotation of the screws F4 and F4 sequentially feeds a quantitative amount of the papermaking sludge P stored in the storage hopper F1 to the drop port F2. It is configured so that it is dropped from 6 .
この場合、図１の如く、上記定量供給部Ｆからの製紙スラッジＰを上記成形固化装置Ｑに供給する搬送コンベヤＱ１が設けられている。尚、搬送コンベヤＱ１を用いずに、上記定量供給部Ｆからの製紙スラッジＰを、直接、成形固化装置Ｑの投入口Ｔに投入する構造とする場合もある。 1, a transport conveyor Q1 is provided to transport the paper sludge P from the quantitative supply section F to the molding and solidifying device Q. In some cases, the transport conveyor Q1 is not used and the paper sludge P from the quantitative supply section F is directly fed into the feed port T of the molding and solidifying device Q.
この場合、図４、図７の如く、上記バレル１は、例えば、合金鋼の鋳物からなり、機台Ｂ上に取付固定され、バレル１の側上部に粉粒状の製紙スラッジＰを投入する投入口Ｔが形成され、バレル１内に二個のスクリュー軸２・２が回転自在に並設され、スクリュー軸２・２に相互に噛み合うスクリュー羽根２ａ・２ａが設けられ、さらに、機台Ｂ上に二個のスクリュー軸２・２を互いに異方向の内向きに回転駆動させ、各スクリュー羽根２ａ・２ａの歯合空間Ｒで製紙スラッジＰを強制的に混練圧縮移送させるための回転駆動機構Ｋが設けられ、バレル１で混練圧縮移送されてくる製紙スラッジＰの成形固化物ＰＦを排出するノズル孔３ａ・３ａ・・を有するダイスプレート３を設け、これにより成形固化装置Ｑが構成され、上記製紙スラッジＰの成形固化物ＰＦとしての鎮静剤Ｇを製造することになる。 In this case, as shown in Figures 4 and 7, the barrel 1 is made of, for example, a casting of alloy steel and is attached and fixed on a machine base B. An inlet T for feeding the powdered paper sludge P is formed on the upper side of the barrel 1. Two screw shafts 2, 2 are rotatably arranged side by side inside the barrel 1. The screw shafts 2, 2 are provided with mutually meshing screw blades 2a, 2a. Further, a rotary drive mechanism K is provided on the machine base B for rotating the two screw shafts 2, 2 inwardly in opposite directions to each other, and forcibly kneading, compressing and transporting the paper sludge P in the meshing space R of each screw blade 2a, 2a. A die plate 3 having nozzle holes 3a, 3a... is provided for discharging the molded solidified product PF of the paper sludge P that is kneaded, compressed and transported in the barrel 1. This constitutes a molding and solidification device Q, and produces a tranquilizer G as a molded solidified product PF of the paper sludge P.
又、この場合、上記回転駆動機構Ｋは、図５、図９の如く、機台Ｂ上に電動モータＭ及び一対の歯車Ｈ１・Ｈ１からなる歯車機構Ｈを設け、電動モータＭにより歯車機構Ｈを介して二個のスクリュー軸２・２を互いに異方向の内向きに回転駆動するように構成している。 In this case, as shown in Figs. 5 and 9, the rotation drive mechanism K is configured such that a gear mechanism H consisting of an electric motor M and a pair of gears H1 , H1 is provided on a machine base B, and the two screw shafts 2, 2 are rotated inwardly in different directions from each other by the electric motor M via the gear mechanism H.
又、この場合、上記含水率調整手段４として、図６の如く、大別して、散水ノズル４ａ及び加水手段Ｃからなり、加水手段Ｃは、流量制御弁、流量センサ、水分計、水量算出部及び流量制御部を備えてなり、水道等の給水源Ｓに接続され、上記バレル１に投入される粉粒状の製紙スラッジＰの含水率は予め乾燥手段等により２５％以上３５％以下に調整されており、この場合、含水率は重量基準含水率を示し、この含水率調整手段４の加水手段Ｃにより上記バレル１内での混練圧縮移送に伴う摩擦熱による製紙スラッジＰの含水率の低下を加味した分の水Ｗを散水ノズル４ａから製紙スラッジＰに加水し、製紙スラッジＰの含水率を上記２５％以上３５％以下に調整するようにしている。 In this case, the moisture content adjusting means 4 is roughly divided into a water sprinkler nozzle 4a and a water supplying means C, as shown in FIG. 6. The water supplying means C is equipped with a flow control valve, a flow sensor, a moisture meter, a water amount calculation unit, and a flow control unit, and is connected to a water supply source S such as a water supply. The moisture content of the powdered paper sludge P put into the barrel 1 is adjusted in advance to 25% to 35% by a drying means or the like. In this case, the moisture content indicates the moisture content by weight. The water supplying means C of the moisture content adjusting means 4 adds water W from the water sprinkler nozzle 4a to the paper sludge P, taking into account the decrease in the moisture content of the paper sludge P due to frictional heat accompanying the kneading, compression, and transport within the barrel 1, to adjust the moisture content of the paper sludge P to the above 25% to 35%.
しかして、バレル１内で混練圧縮移送される製紙スラッジＰの含水率は上記水分計により測定され、上記バレル１内での混練圧縮移送に伴う摩擦熱による製紙スラッジＰの含水率の低下を加味した分の水Ｗを水量算出部により算出し、流量センサを用いて流量制御部により流量制御弁を制御し、製紙スラッジＰに加水して製紙スラッジＰの含水率を上記２５％以上３５％以下に調整するように構成している。 The moisture content of the paper sludge P being kneaded, compressed and transported in the barrel 1 is measured by the moisture meter, and the amount of water W taking into account the decrease in the moisture content of the paper sludge P due to frictional heat associated with the kneading, compression and transport in the barrel 1 is calculated by the water amount calculation unit, and the flow control valve is controlled by the flow control unit using a flow sensor to add water to the paper sludge P to adjust the moisture content of the paper sludge P to the above 25% to 35%.
この場合、含水率調整手段４を構成する水分計として、例えば、赤外線水分計が用いられ、赤外線水分計とは試料としての製紙スラッジＰを赤外線照射により加熱乾燥し、乾燥前の試料の質量を計量し、水分の蒸発による乾燥後の試料の質量を計量し、減量分を水分とみなして含水率を測定するものである。 In this case, for example, an infrared moisture meter is used as the moisture meter constituting the moisture content adjustment means 4. The infrared moisture meter heats and dries the paper sludge P as a sample by irradiating it with infrared rays, measures the mass of the sample before drying, and measures the mass of the sample after drying due to evaporation of the moisture, and measures the moisture content by regarding the weight loss as moisture.
この場合、上記バレル１内での混練圧縮移送に伴う製紙スラッジＰの含水率を２５％以上３５％以下とする理由は、含水率が２５％未満になると上記バレル１で混練圧縮移送されてくる製紙スラッジＰの成形固化物ＰＦを排出するダイスプレート３のノズル孔３ａ・３ａ・・の詰まり現象が生じ、ノズル孔３ａ・３ａ・・の詰まりにより製紙スラッジＰの成形固化物ＰＦの排出が困難となるからであり、一方、含水率が３５％を超えると成形固化物ＰＦが緩くなって固まらず、製紙スラッジＰの成形固化が困難となるからである。 In this case, the reason that the moisture content of the papermaking sludge P associated with the kneading, compression and transport within the barrel 1 is set to 25% or more and 35% or less is that if the moisture content is less than 25%, the nozzle holes 3a, 3a... of the die plate 3, which discharges the molded solidified material PF of the papermaking sludge P being kneaded, compressed and transported within the barrel 1, will become clogged, and the clogging of the nozzle holes 3a, 3a... will make it difficult to discharge the molded solidified material PF of the papermaking sludge P; on the other hand, if the moisture content exceeds 35%, the molded solidified material PF will become loose and will not solidify, making it difficult to mold and solidify the papermaking sludge P.
尚、上記製紙スラッジＰの含水率にあっては、含水率の上限を３０％以下、すなわち、含水率を２５％以上３０％以下とすることがより望ましく、含水率の上限を３０％以下とすることにより、ダイスプレート３のノズル孔３ａ・３ａ・・での製紙スラッジＰの詰まり現象を防ぐことができ、製紙スラッジＰの成形固化を良好に行うことができ、製紙スラッジＰの成形固化物ＰＦとしての鎮静剤Ｇを安定的に製造することができる。 Furthermore, with regard to the moisture content of the papermaking sludge P, it is more desirable to set the upper limit of the moisture content to 30% or less, that is, a moisture content of 25% or more and 30% or less. By setting the upper limit of the moisture content to 30% or less, clogging of the nozzle holes 3a, 3a... of the die plate 3 can be prevented, the papermaking sludge P can be well molded and solidified, and the calming agent G can be stably produced as the molded solidified product PF of the papermaking sludge P.
Ｄはヒーター機構であって、図４、図５の如く、上記バレル１の外周部のダイスプレート３近傍位置に設けられ、上記製紙スラッジＰの混練圧縮移送の運転の初期段階において上記バレル１を加熱するように構成されている。このバレル１を加熱する理由は、例えば、運転の初期段階にあっては、上記バレル１の温度は低いため、製紙スラッジＰの固形化が困難となり、温度が高過ぎると、上記バレル１内の製紙スラッジＰが乾燥し、ダイスプレート３のノズル孔３ａ・３ａ・・での製紙スラッジＰの詰まり現象が生ずるからである。 D is a heater mechanism, which is provided near the die plate 3 on the outer periphery of the barrel 1 as shown in Figures 4 and 5, and is configured to heat the barrel 1 in the initial stage of the operation of kneading, compressing and transporting the papermaking sludge P. The reason for heating the barrel 1 is that, for example, in the initial stage of operation, the temperature of the barrel 1 is low, making it difficult to solidify the papermaking sludge P, and if the temperature is too high, the papermaking sludge P in the barrel 1 dries out, causing clogging of the nozzle holes 3a, 3a, of the die plate 3.
この場合、図４、図６の如く、上記ヒーター機構Ｄに上記バレル１の温度を１００℃以上１４０℃以下に調整するための温度制御手段Ｅが設けられ、温度制御手段Ｅは温度センサ及び温度制御部を備えてなり、製紙スラッジＰの混練圧縮移送の運転の初期段階にあっては、上記バレル１を温度１００℃以上１４０℃以下に加熱し、運転開始後に上記バレル１内での混練圧縮移送に伴う摩擦熱によるバレル１の温度上昇を加味し、過度の温度上昇にあっては、ヒーター機構Ｄの加熱動作を停止し、バレル１の温度低下にあっては、ヒーター機構Ｄの加熱動作を再開し、上記バレル１の温度を１００℃以上１４０℃以下に加熱制御するように構成している。このバレル１を温度１００℃以上１４０℃以下とする理由は、バレル１が温度１００℃未満になると、製紙スラッジＰの固形化が困難となり、加熱温度が１４０℃を超えると上記バレル１内の製紙スラッジＰが乾燥し、ダイスプレート３のノズル孔３ａ・３ａ・・での製紙スラッジＰの詰まり現象が生ずることがあるからである。 In this case, as shown in Figures 4 and 6, the heater mechanism D is provided with a temperature control means E for adjusting the temperature of the barrel 1 to 100°C or higher and 140°C or lower, and the temperature control means E is equipped with a temperature sensor and a temperature control unit. During the initial stage of the operation of kneading, compressing and transporting the papermaking sludge P, the barrel 1 is heated to a temperature of 100°C or higher and 140°C or lower. After the start of operation, the temperature rise of the barrel 1 due to frictional heat associated with the kneading, compressing and transporting within the barrel 1 is taken into consideration. In the event of an excessive temperature rise, the heating operation of the heater mechanism D is stopped, and in the event of a drop in the temperature of the barrel 1, the heating operation of the heater mechanism D is resumed, and the temperature of the barrel 1 is heated and controlled to 100°C or higher and 140°C or lower. The reason for keeping the temperature of barrel 1 at 100°C or higher and 140°C or lower is that if the temperature of barrel 1 is below 100°C, it becomes difficult to solidify the papermaking sludge P, and if the heating temperature exceeds 140°C, the papermaking sludge P in barrel 1 dries out, which can cause clogging of the nozzle holes 3a, 3a, etc. of the die plate 3.
この場合、成形固化装置Ｑからの鎮静剤Ｇを受入容器Ｑ２まで搬送する排出コンベヤＱ３が設けられ、この排出コンベヤＱ３には、図１の如く、成形固化装置Ｑから排出される製紙スラッジＰの成形固化物ＰＦを送風冷却する送風冷却部Ｌが設けられ、この場合、送風冷却部Ｌは冷却機構Ｌ１により送風冷却して搬送する構造とされ、この場合、図１の如く、冷却機構Ｌ１として、送風カバーＬ２、送風ダクトＬ３及び図示省略の送風機からなり、送風機からの風を送風ダクトＬ３を介して製紙スラッジＰの複数個の成形固化物ＰＦ・・に吹き付けて冷却し、高温の成型固化物ＰＦによる火災等の不測の事態を回避するように構成している。 In this case, a discharge conveyor Q3 is provided to transport the sedative G from the molding solidification device Q to a receiving container Q2. As shown in FIG. 1, this discharge conveyor Q3 is provided with an air-blowing cooling section L for blowing air to cool the molded solidified material PF of the paper sludge P discharged from the molding solidification device Q. In this case, the air-blowing cooling section L is structured to transport the paper sludge P while cooling it with air using a cooling mechanism L1 . As shown in FIG. 1, the cooling mechanism L1 is composed of an air-blowing cover L2 , an air-blowing duct L3, and an air blower (not shown), and air from the air blower is blown through the air-blowing duct L3 to the multiple molded solidified materials PF of the paper sludge P to cool them, thereby preventing unexpected events such as fires caused by the high-temperature molded solidified materials PF .
この実施の形態例は上記構成であるから、図１、図１０の如く、人為的又は自動的に、この場合、建設機械Ｎにより、上記製紙スラッジＰが定量供給部Ｆに投入され、定量供給部Ｆに製紙スラッジＰを貯留して定量供給すると、搬送コンベヤＱ１を介して成形固化装置Ｑの投入口Ｔに投入され、定量供給部Ｆからの製紙スラッジＰを成形固化装置Ｑのバレル１内で混練圧縮移送して成形固化物ＰＦが排出され、成形固化物ＰＦは排出コンベヤＱ３を介して受入容器Ｑ２に収納され、この際、成形固化装置Ｑからの成形固化物ＰＦは送風冷却部Ｌにより送風冷却され、高温の成型固化物ＰＦによる火災等の不測の事態を回避することができ、成形固化物ＰＦとしての鎮静剤Ｇが製造されることになり、この際、上記成形固化装置Ｑは、上記製紙スラッジＰが投入されるバレル１内に二個のスクリュー軸２・２を回転自在に並設し、各スクリュー軸２・２に相互に噛み合うスクリュー羽根２ａ・２ａを設け、二個のスクリュー軸２・２を互いに異方向の内向きに回転駆動させ、各スクリュー羽根２ａ・２ａの歯合空間Ｒで製紙スラッジＰを強制的に混練圧縮移送させるための回転駆動機構Ｋを設け、バレル１内で混練圧縮移送されてくる製紙スラッジＰの成形固化物ＰＦを排出するノズル孔３ａ・３ａ・・を有するダイスプレート３を設け、上記バレル１内で混練圧縮移送される上記製紙スラッジＰの含水率を調整する含水率調整手段４を設けてなるから、定量供給部Ｆから搬送コンベヤＱ１を介してバレル１の投入口Ｔに製紙スラッジＰが投入され、上記回転駆動機構Ｋによりバレル１内の二個のスクリュー軸２・２が回転駆動され、スクリュー軸２・２はスクリュー羽根２ａ・２ａが相互に噛み合う互いに異方向の内向きに回転駆動され、各スクリュー羽根２ａ・２ａの歯合空間Ｒで製紙スラッジＰは強制的に混練圧縮移送され、混練圧縮により製紙スラッジＰの繊維は絡み合い、バレル１内で混練圧縮移送されてくる製紙スラッジＰはダイスプレート３のノズル孔３ａ・３ａ・・から排出され、製紙スラッジＰは成形固化され、製紙スラッジＰの成形固化物ＰＦとしての鎮静剤Ｇを製造することができ、この際、上記バレル１内で混練圧縮移送される上記製紙スラッジＰの含水率を調整する含水率調整手段４を設けているから、上記バレル１内での混練圧縮移送に伴う摩擦熱による製紙スラッジＰの含水率の低下を加味した分の水Ｗを製紙スラッジＰに加水することができ、製紙スラッジＰの成形固化を良好に行うことができ、製紙スラッジＰの成形固化物ＰＦとしての鎮静剤Ｇの製造効率を向上することができる。 Since this embodiment has the above-mentioned configuration, as shown in Figs. 1 and 10, the paper sludge P is manually or automatically input into the quantitative supply section F by the construction machine N, and when the paper sludge P is stored in the quantitative supply section F and supplied in a quantitative manner, it is input into the input port T of the molding and solidification device Q via the transfer conveyor Q1 , and the paper sludge P from the quantitative supply section F is kneaded, compressed and transferred in the barrel 1 of the molding and solidification device Q to discharge the molded solidified material PF , which is then stored in the receiving container Q2 via the discharge conveyor Q3 , and at this time, the molded solidified material PF from the molding and solidification device Q is cooled by air blowing through the air blowing cooling section L, making it possible to avoid unexpected situations such as fires caused by the high-temperature molded solidified material PF , and the molded solidified material PF is then discharged. In this case, the molding and solidifying device Q is provided with two screw shafts 2, 2 rotatably arranged in a barrel 1 into which the papermaking sludge P is fed, with mutually meshing screw blades 2a, 2a provided on each screw shaft 2, 2, a rotary drive mechanism K for rotating the two screw shafts 2, 2 inwardly opposite directions to each other, and forcibly kneading, compressing and transporting the papermaking sludge P in the meshing space R of the screw blades 2a, 2a, a die plate 3 having nozzle holes 3a, 3a... for discharging the molded solidified product PF of the papermaking sludge P kneaded, compressed and transported in the barrel 1, and a moisture content adjusting means 4 for adjusting the moisture content of the papermaking sludge P kneaded, compressed and transported in the barrel 1. The papermaking sludge P is fed into the inlet T of the barrel 1 through the nozzle hole 1 , and the two screw shafts 2, 2 in the barrel 1 are rotated by the rotary drive mechanism K. The screw shafts 2, 2 are rotated inward in different directions so that the screw blades 2a, 2a mesh with each other, and the papermaking sludge P is forcibly kneaded, compressed and transported in the meshing spaces R of the screw blades 2a, 2a. The fibers of the papermaking sludge P become entangled by the kneading and compression, and the papermaking sludge P that has been kneaded, compressed and transported in the barrel 1 is discharged from the nozzle holes 3a, 3a... of the die plate 3, and the papermaking sludge P is molded and solidified. The molded solidified product P of the papermaking sludge P is In this case, since a moisture content adjusting means 4 is provided for adjusting the moisture content of the papermaking sludge P being kneaded, compressed and transported within the barrel 1, water W can be added to the papermaking sludge P taking into account the decrease in the moisture content of the papermaking sludge P due to frictional heat accompanying the kneading, compression and transport within the barrel 1, and the papermaking sludge P can be molded and solidified well, thereby improving the production efficiency of the molded solidified product PF of the papermaking sludge P, which is a sedative G.
この場合、上記バレル１に投入される製紙スラッジＰの含水率は予め２５％以上３５％以下に調整され、上記含水率調整手段４に上記バレル１内での混練圧縮移送に伴う摩擦熱による製紙スラッジＰの含水率の低下を加味した分の水Ｗを製紙スラッジＰに加水し、製紙スラッジＰの含水率を上記２５％以上３５％以下に調整する加水手段Ｃを備えてなるから、上記バレル１内での混練圧縮移送に伴う製紙スラッジＰの含水率を２５％以上３５％以下とすることによりノズル孔３ａ・３ａ・・の詰まり現象を防ぐことができ、成形固化物ＰＦの成形固化を確実に行うことができ、製紙スラッジＰの成形固化物ＰＦとしての鎮静剤Ｇを安定的に製造することができる。 In this case, the moisture content of the papermaking sludge P fed into the barrel 1 is adjusted in advance to 25% or more and 35% or less, and the moisture content adjusting means 4 is equipped with a moisture adding means C which adds water W to the papermaking sludge P taking into account the decrease in the moisture content of the papermaking sludge P due to frictional heat accompanying the kneading, compression and transport within the barrel 1, thereby adjusting the moisture content of the papermaking sludge P to the above 25% or more and 35% or less. Therefore, by setting the moisture content of the papermaking sludge P accompanying the kneading, compression and transport within the barrel 1 to 25% or more and 35% or less, clogging of the nozzle holes 3a, 3a... can be prevented, the molding and solidification of the molded solidified material PF can be reliably performed, and the calming agent G as the molded solidified material PF of the papermaking sludge P can be stably produced.
この際、上記バレル１に投入される製紙スラッジＰの含水率は予め２５％以上３０％以下に調整され、上記含水率調整手段４に上記バレル１内での混練圧縮移送に伴う摩擦熱による製紙スラッジＰの含水率の低下を加味した分の水Ｗを製紙スラッジＰに加水し、製紙スラッジＰの含水率を上記２５％以上３０％以下に調整する加水手段Ｃを備えることにより、上記バレル１内での混練圧縮移送に伴う製紙スラッジＰの含水率を２５％以上３０％以下とすることによりノズル孔３ａ・３ａ・・の詰まり現象を防ぐことができ、成形固化物ＰＦの成形固化を一層確実に行うことができ、製紙スラッジＰの成形固化物ＰＦとしての鎮静剤Ｇを安定的に製造することができる。 In this case, the moisture content of the papermaking sludge P fed into the barrel 1 is adjusted in advance to 25% or more and 30% or less, and the moisture content adjusting means 4 is provided with a moisture adding means C which adds water W to the papermaking sludge P taking into account the decrease in the moisture content of the papermaking sludge P due to frictional heat accompanying the kneading, compression and transport within the barrel 1, thereby adjusting the moisture content of the papermaking sludge P to the above 25% or more and 30% or less.

この場合、図４、図５の如く、上記製紙スラッジＰの混練圧縮移送の運転の初期段階において、上記バレル１を加熱するヒーター機構Ｄを設けてなるから、製紙スラッジＰの固形化を確実に行うことができ、ダイスプレート３のノズル孔３ａ・３ａ・・での製紙スラッジＰの詰まり現象を防ぐことができ、成形固化物ＰＦの成形固化を確実に行うことができ、製紙スラッジＰの成形固化物ＰＦとしての鎮静剤Ｇを安定的に製造することができ、又、この場合、図４、図６の如く、上記ヒーター機構Ｄに上記バレル１の温度を１００℃以上１４０℃以下に調整するための温度制御手段Ｅを設けてなるから、製紙スラッジＰの混練圧縮移送の運転の初期段階にあっては、上記バレル１を温度１００℃以上１４０℃以下に加熱し、運転開始後に上記バレル１内での混練圧縮移送に伴う摩擦熱によるバレル１の温度上昇を加味し、過度の温度上昇にあっては、ヒーター機構Ｄの加熱動作を停止し、バレル１の温度低下にあっては、ヒーター機構Ｄの加熱動作を再開し、上記バレル１の温度を１００℃以上１４０℃以下に加熱制御することができ、ダイスプレート３のノズル孔３ａ・３ａ・・での製紙スラッジＰの詰まり現象を防ぐことができ、成形固化物ＰＦの成形固化を一層確実に行うことができ、製紙スラッジＰの成形固化物ＰＦとしての鎮静剤Ｇを安定的に製造することができる。 In this case, as shown in FIG. 4 and FIG. 5, a heater mechanism D is provided for heating the barrel 1 in the initial stage of the operation of kneading, compressing and transporting the papermaking sludge P. Therefore, the papermaking sludge P can be reliably solidified, and the clogging phenomenon of the papermaking sludge P in the nozzle holes 3a, 3a, of the die plate 3 can be prevented. Therefore, the molding and solidification of the molded solidified material P F can be reliably performed, and the molded solidified material P F of the papermaking sludge P can be reliably solidified. In this case, as shown in FIG . 4 and FIG. 6, the heater mechanism D is provided with a temperature control means E for adjusting the temperature of the barrel 1 to 100°C or more and 140°C or less. Therefore, in the initial stage of the operation of kneading, compressing and transferring the papermaking sludge P, the barrel 1 is heated to a temperature of 100°C or more and 140°C or less. After the start of the operation, the temperature of the barrel 1 is increased due to frictional heat caused by the kneading, compressing and transferring in the barrel 1. In the event of an excessive increase in temperature, the heating operation of the heater mechanism D is stopped. In the event of a decrease in temperature of the barrel 1, the heating operation of the heater mechanism D is resumed. This makes it possible to heat and control the temperature of the barrel 1 to 100°C or more and 140°C or less. This makes it possible to prevent the papermaking sludge P from clogging the nozzle holes 3a, 3a, of the die plate 3, and the molding and solidification of the molded solidified material PF can be more reliably performed. As a result, the molded and solidified material PF of the papermaking sludge P can be stably produced as the sedative G.
