【考案の詳細な説明】
本考案はモルタルの混線を先にしてこれに骨材を混練す
るコンクリートの二股混線装置に係るもので、コンクリ
ートの品質向上と生コンクリートの製造能率を著しく向
上させることを目的としたものである。[Detailed description of the invention] This invention relates to a two-way concrete mixing device that mixes mortar first and then mixes aggregate into it, and aims to significantly improve the quality of concrete and the production efficiency of ready-mixed concrete. This is the purpose.
その詳細を図によって説明するとコンクリートのミキサ
ー1の駆動モーターを可変速モーター2となし、ミキサ
一本体上方に連接する砂計量器3、水計量器4、砂利計
量器5、セメント計量器6のうち、水計量器4に電子式
水排出比較器10で排出重量を検出し、制後開閉作動す
る水排出弁7とその排出弁シリンダー8を設け、AE剤
計量器9を連接したことを特徴としたものである。To explain the details with a diagram, the driving motor of the concrete mixer 1 is a variable speed motor 2, and among the sand measuring device 3, water measuring device 4, gravel measuring device 5, and cement measuring device 6 connected above the mixer body. , the water meter 4 is equipped with a water discharge valve 7 and its discharge valve cylinder 8 which detect the discharge weight with an electronic water discharge comparator 10 and open/close after control, and an AE agent meter 9 is connected thereto. This is what I did.
Lは水排出弁全ストローク、lは水排出弁一段排出高さ
を示した。L indicates the full stroke of the water discharge valve, and l indicates the discharge height of the first stage of the water discharge valve.
コンクリート製造プラントに於ける作業方法は通常は砂
利、砂、セメント、水その他材料を同時にミキサーに供
給して混練しているが、このコンクリートは所謂ブリー
ジング現象により水分が分離上昇して骨材の沈降が生じ
たり、強度にバラつきがあり、又、モルタル混線を先行
させれば、1サイクルの時間が長くなるなどの欠点があ
った。The working method in concrete manufacturing plants is usually to feed gravel, sand, cement, water, and other materials into a mixer at the same time and mix them, but this concrete is produced by the so-called breathing phenomenon, which causes moisture to separate and rise, causing aggregate to settle. There were disadvantages such as the occurrence of cracks, variations in strength, and if the mortar was mixed in advance, the time for one cycle would be longer.
本願に於ではプラント内の砂計量器3、水計量器4、砂
利計量器5、セメント計量器6が夫々配合材料を計量し
終ると、先づ砂と水が排出してミキサー1に供給される
。In this application, when the sand measuring device 3, water measuring device 4, gravel measuring device 5, and cement measuring device 6 in the plant finish measuring the mixed materials, sand and water are first discharged and supplied to the mixer 1. Ru.
そしてこのとき、水計量器の水排出弁7はその全ストロ
ークLのうち4分の1開いて計量水のうち小部分が正確
にミキサー内に供給される。At this time, the water discharge valve 7 of the water meter is opened by a quarter of its total stroke L, so that a small portion of the metered water is accurately supplied into the mixer.
そしてこの減量を電子式の水排出比較器が検出して排出
信号を切り、水を小量供給後の水排出弁を閉じる。An electronic water discharge comparator detects this loss, turns off the discharge signal, and closes the water discharge valve after supplying a small amount of water.
この間ミキサーは定格の4倍の高速度で回転していて、
約5秒間混練される。During this time, the mixer was rotating at a high speed four times its rated speed.
Knead for about 5 seconds.
次にセメント計量器6からセメントが排出供給され、ミ
キサー内で砂、セメントそして少量の水とで約5秒間混
合され一定粘度のモルタルが短時間で練り上る。Next, cement is discharged and supplied from the cement measuring device 6, and mixed with sand, cement, and a small amount of water in a mixer for about 5 seconds to knead mortar with a constant viscosity in a short time.
この第1段の練り時間合計10秒は定格回転の40秒練
りに相当し、充分に混練される。The total kneading time of this first stage is 10 seconds, which corresponds to 40 seconds of kneading at the rated rotation, and sufficient kneading is achieved.
次に可変速モーター2を減速して定格の低速回転でミキ
サーを回転し、水排出弁は全開して、AE剤と共に全量
供給し、同時に骨材も供給する。Next, the variable speed motor 2 is decelerated to rotate the mixer at the rated low speed, the water discharge valve is fully opened, and the entire amount is supplied together with the AE agent, and at the same time, the aggregate is also supplied.
このように第2段階で残り骨材、AE剤、水のすべてが
ミキサーに供給され、第1段階の混線時間10秒を普通
の混線時間の約30秒から差し引いた20秒間練ると、
既に充分流動性の生じたモルタルの中に骨材が供給され
るから、混線抵抗少く従来行われている全種同時供給混
線方法と変らない時間で、又従来の2段練り方法より短
い時間で混線が完了する。In this way, all of the remaining aggregate, AE agent, and water are supplied to the mixer in the second stage, and the mixture is kneaded for 20 seconds, subtracting the 10 seconds of mixing time in the first stage from the normal mixing time of about 30 seconds.
Since the aggregate is fed into the mortar which has already developed sufficient fluidity, the cross-mixing resistance is low and the time required is the same as the conventional method of simultaneously feeding all types of cross-wires, and it is also shorter than the conventional two-stage mixing method. The crosstalk is completed.
この場合有効混線時間は(10X4+20)=60秒と
なる。In this case, the effective crosstalk time is (10X4+20)=60 seconds.
以上の如く可変速ミキサーと二段排出弁をもつ水計量器
の組み合せによって、能率的に二段混線ができ、水分の
分離上昇は少く、流動性があって強度の大きい生コンク
リートが能率的に製造できる効果があるものである。As described above, by combining a variable speed mixer and a water meter with a two-stage discharge valve, two-stage cross-mixing can be performed efficiently, the separation and rise of water is small, and fresh concrete with fluidity and high strength can be produced efficiently. It is something that can be manufactured and has an effect.
