本考案は押出造粒機に関し、詳しくは機内の不必要な摩
擦を抑え動力超過なく安定に運転できる押出造粒機に関
する。[Detailed Description of the Invention] The present invention relates to an extrusion granulator, and more particularly to an extrusion granulator that can suppress unnecessary friction inside the machine and operate stably without excessive power.
近時、ビートパルプを利用してペレット化し家畜用飼料
とする技術が開発されているが、その製造の最終工程の
ペレット化には、各種の押出造粒機が使用される。Recently, technology has been developed to use beet pulp to pelletize it into livestock feed, and various extrusion granulators are used for the final step of pelletization.
このような押出造粒機として、例えば、多数の小孔を円
筒壁に貫通して設けられた回転円筒に、その内面に摺触
する回転自在な押出ローラを配設し、該回転円筒を回転
することにより該回転円筒内に導入された原料を該ロー
ラと該回転円筒壁間において圧縮して該原料を該小孔ン
から押出して造粒するものがある。As such an extrusion granulator, for example, a rotatable extrusion roller that slides on the inner surface of a rotary cylinder that has a large number of small holes penetrating the cylinder wall is disposed, and the rotary cylinder is rotated. There is a method in which the raw material introduced into the rotating cylinder is compressed between the roller and the wall of the rotating cylinder, and the raw material is extruded through the small holes and granulated.
この種の押出造ね機においては、ローラの回転は、回転
円筒壁あるいは圧縮された原料を介して摩擦力により伝
達される。In this type of extrusion machine, the rotation of the rollers is transmitted by frictional force through the rotating cylindrical wall or the compressed raw material.
したがって、ビートパルプのような糖分等を含む原料を
押出すために加熱、加湿した状ｉ態においては、糖分そ
の他有機質にまりローラの回転摺動部の摩擦力を増大さ
せることになり、しばしばローラの回転不能を誘発し、
又、原料をスクリューによって強制的に供給しているた
めローラを含む中心部に集中的に原料が圧縮されローラ
の回転を不能にしていた。Therefore, when raw materials containing sugar, such as beet pulp, are heated and humidified for extrusion, the sugar and other organic substances become trapped, increasing the frictional force on the rotating and sliding portion of the roller. induces inability to rotate,
In addition, since the raw material is forcibly fed by a screw, the raw material is compressed intensively in the center including the rollers, making it impossible for the rollers to rotate.
更に又、原料はスクリューにより強制的に供給され、原
料の性状が変化した場合においても押出し能力の低下に
関係なく供給されるので、回転円筒の回転に過大な動力
を要する結果となっていた。Furthermore, the raw material is forcibly fed by the screw, and even if the properties of the raw material change, it is fed regardless of a decrease in extrusion capacity, resulting in an excessive amount of power being required to rotate the rotating cylinder.
本考案はこのような現状に鑑みてなされたものであり、
その目的は、押出造粒機内の不必要な摩擦を抑え動力超
過なく安定運転のできる押出造粒機を提供することであ
る。This idea was made in view of the current situation,
The purpose is to provide an extrusion granulator that can suppress unnecessary friction within the extrusion granulator and can operate stably without excessive power.
本考案は上記目的を達成するため次の構成をとるもので
ある。The present invention has the following configuration to achieve the above object.

とを特徴とするものである。That is, the extrusion granulator of the present invention includes a rotary cylinder 3 having a large number of small holes 4 penetrating the cylinder body wall, and a plurality of rotatable cylinders arranged so as to be in sliding contact with the inner surface of the rotary cylinder 3. It consists of an extrusion roller 8, a fixed shaft 5 that rotatably supports the extrusion roller 8, and a feeder 10 provided in front of the opening of the rotating cylinder 3 and equipped with a screw 12, and the raw material supplied from the feeder 10. In an extrusion granulator that compresses and extrudes from the small hole 4 by the rotation of the extrusion roller 8 accompanying the rotation of the rotary cylinder 3, a The present invention is characterized in that a baffle plate 11 is provided inside the feed material receiving port of the conical cylinder 9.

押出される。According to the present invention, the raw material quantitatively supplied from the feeder 10 by the screw 12 reaches the buckle plate 11 fixedly provided at the outlet of the feeder 10, and the outer periphery of the baffle plate 11 and the rotating cylinder 3 are connected to each other. It passes through the annular gap between the conical tube 9 attached to the cylindrical body and is supplied to the space inside the rotating cylinder 3 excluding the extrusion roller 8, and is compressed by the extrusion roller 8 to form the small hole 4 of the rotating cylinder 3. extruded from.

ローラ８の回転不能等を誘引することなく安定に運転す
ることができる。Since the conventional extrusion granulator is not provided with this baffle plate 11, the raw material supplied from the feeder 10 applies more pressure than necessary inside the rotating cylinder 3, which may prevent the extrusion roller 8 from rotating or Even if a buckle plate is provided, only one baffle plate is fixed to the rotating roller side, and abnormal power is caused only to a specific rotating roller. However, when the baffle plate 11 is fixedly provided at the outlet of the feeder 10 according to the present invention, the baffle plate 11
The resistance when the raw material passes through the annular gap formed at the outer periphery of the feeder only affects the power of the screw 12 of the feeder 10, and the amount of raw material supplied can be controlled simply by controlling this power. , it is possible to operate stably without inducing excessive power or inability to rotate the extrusion roller 8, which has been observed in the past.
又、該バックルプレート１１を設けることにより、該間
隙において、原料は一次圧縮されて密度が増し、その後
押出ローラ８により更に圧縮されるため、処理能力も増
大される。Further, by providing the buckle plate 11, the raw material is primarily compressed in the gap to increase its density, and then further compressed by the extrusion roller 8, so that the processing capacity is also increased.
このように、本考案によれば、原料を圧縮して押出すの
