Description
本考案は、パルパー装置に係り、特に、離解に要する時間の短縮化を図ったパルパー装置に関する。 The present invention relates to a pulper device, and more particularly to a pulper device designed to shorten the time required for disaggregation.
製紙原料を離解させるパルパー装置P’がある(図6乃至図8参照)。
このパルパー装置P’は、ローター3’の中央に底面の半径r’、高さh’である略円錐形状のロ−ターキャップ4’が設けられ、槽1’内に製紙原料5’を引き込み、離解させるようにしている。
There is a pulper device P ′ that disaggregates the papermaking raw material (see FIGS. 6 to 8).
This pulper device P ′ is provided with a rotor cap 4 ′ having a substantially conical shape having a bottom surface radius r ′ and a height h ′ at the center of the rotor 3 ′, and draws the papermaking raw material 5 ′ into the tank 1 ′. , I try to let them disaggregate.
しかしながら、パルパー装置P’には、図示しないコンベアーで搬送されてきた製紙原料5’が投入されるが、この製紙原料5’は圧縮された古紙等で、その状態のままパルパー装置P’内に投入されるため、投入直後はほぐれにくく、十分に離解するには時間を要する、つまり、製紙原料5’は、図6に示すように、槽1’の底部に引き込みされにくく、引き込みに要する時間がかかるという問題点があった。 However, the papermaking raw material 5 ′ that has been conveyed by a conveyor (not shown) is fed into the pulper device P ′. Since it is introduced, it is difficult to loosen immediately after the introduction, and it takes time to sufficiently disaggregate. That is, the papermaking raw material 5 ′ is not easily drawn into the bottom of the tank 1 ′ as shown in FIG. There was a problem that it took.
本考案者は、鋭意研究した結果、ロ−ターキャップの底面の半径r’がロ−ターキャップの高さh’より大であるため、製紙原料がロ−ターキャップにより槽の下部へと案内されにくいということを見出した。 As a result of diligent research, the inventor has found that the radius r ′ of the bottom surface of the rotor cap is larger than the height h ′ of the rotor cap, so that the papermaking raw material is guided to the lower part of the tank by the rotor cap. I found that it was hard to be done.
本考案は、上記の問題点を考慮してなされたもので、離解に要する時間の短縮化を図ったパルパー装置を提供することである。 The present invention has been made in consideration of the above-mentioned problems, and is to provide a pulper device that shortens the time required for disaggregation.
請求項1記載のパルパー装置は、上部に製紙原料投入口、下部に排出口を有し、製紙原料と水を受け入れる槽と、この槽の前記排出口を覆うように設けられたストレーナと、前記槽内に設けられ、前記製紙原料を離解させる羽根を有するローターとを備え、前記槽内に前記ローター及び前記ストレーナが配置され、前記ストレーナの上に前記ローターが位置し、前記ローターの中央に底面の半径r、高さhである略円錐形状のロ−ターキャップが設けられ、前記ロ−ターキャップの前記底面の半径rより前記ロ−ターキャップの高さhが大である(r<h)。 The pulper device according to claim 1 has a papermaking raw material inlet at an upper portion and a discharge port at a lower portion, a tank for receiving a papermaking raw material and water, a strainer provided so as to cover the outlet of the tank, And a rotor having blades for separating the papermaking raw material, the rotor and the strainer are disposed in the tank, the rotor is positioned on the strainer, and a bottom surface in the center of the rotor. A rotor cap having a substantially conical shape with a radius r and a height h is provided, and the height h of the rotor cap is larger than the radius r of the bottom surface of the rotor cap (r <h). ).
請求項1記載のパルパー装置によれば、槽内にローター及びストレーナが配置され、前記ストレーナの上に前記ローターが位置し、前記ローターの中央に底面の半径r、高さhである略円錐形状のロ−ターキャップが設けられ、前記ロ−ターキャップの前記底面の半径rより前記ロ−ターキャップの前記高さが大である(r<h)ため、製紙原料はロ−ターキャップにより斜めに傾けられ槽内を回流し、回流する製紙原料は離解能力が大きいローター外周側にある羽根により離解され、つまり、槽内に投入された製紙原料がロ−ターキャップにより斜めに傾けられ、製紙原料を槽の底部に引き込み易くなり、製紙原料が槽内を回流に要する時間が短くなって、効率良く離解させることができる。 According to the pulper device according to claim 1, a rotor and a strainer are arranged in the tank, the rotor is positioned on the strainer, and a substantially conical shape having a bottom surface radius r and a height h at the center of the rotor. And the height of the rotor cap is larger than the radius r of the bottom surface of the rotor cap (r <h), so that the papermaking raw material is slanted by the rotor cap. The papermaking raw material that circulates in the tank and is circulated is separated by the blades on the outer peripheral side of the rotor, which has a large disaggregation ability. It becomes easy to draw the raw material into the bottom of the tank, and the time required for the papermaking raw material to circulate in the tank is shortened, and can be efficiently disaggregated.
本考案の一実施例のパルパー装置を図1乃至図5を参照して説明する。
図1及び図2に示すPは槽1内にパルプ、古紙等の製紙原料5を投入して水中で離解させるパルパー装置で、このパルパー装置Pは、上部に製紙原料投入口1a、下部に排出口(図示せず)を有し、製紙原料5と水を受け入れる槽1を有している。
A pulper device according to an embodiment of the present invention will be described with reference to FIGS.
P shown in FIG. 1 and FIG. 2 is a pulper device in which a papermaking raw material 5 such as pulp and waste paper is put into a tank 1 and disaggregated in water. It has an outlet (not shown) and a tank 1 for receiving papermaking raw material 5 and water.
図1に示す2は、槽1の排出口(図示せず)を覆うように設けられたストレーナで、3は槽1内に設けられ、製紙原料5を離解させる羽根3aを有するローターである。
図1に示すように、槽1内にローター3及びストレーナ2が配置され、ストレーナ2の上にローター3が位置している。
ローター3の中央には、図2に示すように、底面の半径r、高さhである略円錐形状のロ−ターキャップ4が設けられている。
ロ−ターキャップ4の底面の半径rよりロ−ターキャップ4の高さが大となっている(r<h)。
1 is a strainer provided so as to cover a discharge port (not shown) of the tank 1, and 3 is a rotor provided in the tank 1 and having blades 3 a for separating the papermaking raw material 5.
As shown in FIG. 1, the rotor 3 and the strainer 2 are disposed in the tank 1, and the rotor 3 is positioned on the strainer 2.
At the center of the rotor 3, as shown in FIG. 2, a substantially conical rotor cap 4 having a bottom surface radius r and a height h is provided.
The height of the rotor cap 4 is larger than the radius r of the bottom surface of the rotor cap 4 (r <h).
従って、上述したパルパー装置Pによれば、パルプ、古紙等の製紙原料5は、槽1内へ図示しないコンベアにより連続的又は不連続的に供給され、また、水は図示しないパイプにより槽1内へ供給され、槽1内の製紙原料5はロ−ターキャップ4により斜めに傾けられ槽1内を回流し、回流する製紙原料5は離解能力が大きいローター3の外周側にある羽根3aにより離解され、つまり、槽1内に投入された製紙原料5が、ロ−ターキャップ4により斜めに傾けられ、図2に示すように、製紙原料5を槽1の底部に引き込み易くなり、製紙原料5が槽1内を回流に要する時間が短くなって、効率良く離解させることができる。
なお、槽1内で離解された製紙原料5は、ストレーナ2、排出口(図示せず)、パイプ(図示せず)により、槽1外へと排出されるようになっている。
Therefore, according to the above-described pulper apparatus P, the papermaking raw material 5 such as pulp and waste paper is continuously or discontinuously supplied into the tank 1 by a conveyor (not shown), and water is supplied into the tank 1 by a pipe (not shown). The papermaking raw material 5 in the tank 1 is inclined obliquely by the rotor cap 4 and circulates in the tank 1, and the circulating papermaking raw material 5 is disaggregated by the blade 3a on the outer peripheral side of the rotor 3 having a large disaggregation ability. That is, the papermaking raw material 5 thrown into the tank 1 is inclined obliquely by the rotor cap 4, and the papermaking raw material 5 is easily drawn into the bottom of the tank 1, as shown in FIG. However, the time required for the circulation in the tank 1 is shortened, and it can be efficiently disaggregated.
In addition, the papermaking raw material 5 disaggregated in the tank 1 is discharged | emitted out of the tank 1 by the strainer 2, the discharge port (not shown), and a pipe (not shown).
