Abstract

<P>PROBLEM TO BE SOLVED: To provide a rotary kiln used in a cement manufacturing process in which an outer peripheral face of a supporting washer supported by a tire is not ripped out. <P>SOLUTION: In the rotary kiln 3, a shell 2 is rotationally driven at a predetermined speed with cement supplied inside. A supporting roller 9 rollable with respect to the tire 5 when the shell 2 is turned is assembled to the supporting washer 4 fixed to the outer peripheral face of the shell 2 and interposed between the shell 2 and the tire 5. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明はロータリキルンに関する。   The present invention relates to a rotary kiln.

図3〜図5に示すように、従来からセメントの製造工程においては、内周面に耐火煉瓦1が貼設された円筒状のシェル2を備えたロータリキルン3を回転自在に設け、このロータリキルン3の内部に所定のセメントを供給して焼成等の所定の処理を行うようになっている。   As shown in FIGS. 3 to 5, conventionally, in a cement manufacturing process, a rotary kiln 3 including a cylindrical shell 2 having a fire brick 1 attached to an inner peripheral surface thereof is rotatably provided. A predetermined cement is supplied into the kiln 3 to perform a predetermined process such as firing.

このような従来のロータリキルン3においては、シェル2の軸線方向に所要の間隔を置いて複数箇所に、外周面円周方向へ所定間隔で複数の支持座金4を固設し、支持座金4の外周に外嵌したタイヤ5を介してシェル2を、支持枠6に設置したローラ7に回転自在に支持させている。図中、8は図示してない駆動装置を介して駆動されるギヤ等の動力伝達手段である。   In such a conventional rotary kiln 3, a plurality of support washers 4 are fixed at predetermined intervals in the circumferential direction of the outer peripheral surface at a plurality of locations at predetermined intervals in the axial direction of the shell 2. The shell 2 is rotatably supported by a roller 7 installed on a support frame 6 via a tire 5 fitted on the outer periphery. In the figure, reference numeral 8 denotes a power transmission means such as a gear driven via a drive device (not shown).

而して、前記ロータリキルン3の内部に所定のセメントを供給した状態で、駆動装置及び動力伝達手段8を介してシェル2を所定速度で回転駆動させると、ローラ7に支持されたタイヤ5は支持座金4を介してシェル2と一緒に回転駆動されるようになっている。   Thus, when the shell 2 is rotationally driven at a predetermined speed via the driving device and the power transmission means 8 in a state where the predetermined cement is supplied into the rotary kiln 3, the tire 5 supported by the roller 7 is It is rotated together with the shell 2 via the support washer 4.

ここで、シェル2が熱膨張により増大することを考慮して、シェル2の外周に外嵌固定されている支持座金4の外径はタイヤ5の内径よりも小さく形成されており、これらの外径と内径との差により、シェル2及びタイヤ5の回転時に支持座金4はタイヤ5の内面に対し僅かに摺動する。   Here, considering that the shell 2 increases due to thermal expansion, the outer diameter of the support washer 4 that is externally fitted and fixed to the outer periphery of the shell 2 is formed smaller than the inner diameter of the tire 5. Due to the difference between the diameter and the inner diameter, the support washer 4 slides slightly against the inner surface of the tire 5 when the shell 2 and the tire 5 are rotated.

ロータリキルンの先行技術文献としては特許文献1があり、図3〜図5に示すものと同様な構成を有している。
特開2002−173693号公報
As a prior art document of a rotary kiln, there is Patent Document 1, which has a configuration similar to that shown in FIGS.
JP 2002-173893 A

上述の支持座金4は平板状の普通炭素鋼を円弧状に曲折させたもので、鍛造鋼製のタイヤ5内周面と支持座金4の外周面は面接触するため、接触状態によって支持座金4の外周面がむしり取られ、支持座金4とタイヤ5とは損耗する虞がある。この点は、特許文献1に示すロータリキルンにおいても同様である。   The above-described support washer 4 is obtained by bending a flat plain carbon steel into an arc shape, and the inner peripheral surface of the forged steel tire 5 and the outer peripheral surface of the support washer 4 are in surface contact. The outer peripheral surface of the support washer 4 is peeled off, and the support washer 4 and the tire 5 may be worn out. This also applies to the rotary kiln disclosed in Patent Document 1.

本発明は、上記実情に鑑み、タイヤに支持される支持座金の外周面がむしり取られることがないようにしたロータリキルンを提供することを目的としてなしたものである。   In view of the above circumstances, an object of the present invention is to provide a rotary kiln in which an outer peripheral surface of a support washer supported by a tire is not peeled off.

本発明のロータリキルンは、シェルの外周面に固設されて該シェルを支持するタイヤとの間に介在する支持座金に、前記シェルの回転時に前記タイヤに対し転動し得るようにした支持ローラを組み込んだものである。   The rotary kiln of the present invention is a support roller fixed to the outer peripheral surface of the shell and interposed between the tire and the tire that supports the shell, so that the roller can roll with respect to the tire when the shell rotates. Is incorporated.

本発明のロータリキルンによれば、支持座金にシェルの回転時にタイヤに対し転動し得るようにした支持ローラを組み込んでいるため、タイヤの相対摩擦力が低減し、むしり取りによる損耗が防止されるという優れた効果を奏し得る。   According to the rotary kiln of the present invention, since the support washer is incorporated in the support washer so that it can roll with respect to the tire during rotation of the shell, the relative frictional force of the tire is reduced and wear due to peeling is prevented. An excellent effect can be achieved.

以下、本発明の実施の形態を添付図面を参照して説明する。
図1、図2は本発明を実施する形態の一例である。而して、本図示例では、各支持座金4のタイヤ5に対向する面は凹形状に形成され、該凹形状の部分には、タイヤ5の内周面に当接し得る複数の支持ローラ9がシェル2と平行に組み込まれている。図中、10はシェル2の外周に固設された座金止めである。なお、図中、図3〜図5に示すものと同一のものには同一の符号が付してある。
Embodiments of the present invention will be described below with reference to the accompanying drawings.
1 and 2 are examples of embodiments for carrying out the present invention. Thus, in the illustrated example, the surface of each support washer 4 facing the tire 5 is formed in a concave shape, and a plurality of support rollers 9 that can come into contact with the inner peripheral surface of the tire 5 are formed in the concave portion. Is incorporated in parallel with the shell 2. In the figure, reference numeral 10 denotes a washer stopper fixed to the outer periphery of the shell 2. In addition, the same code | symbol is attached | subjected to the thing same as what is shown in FIGS. 3-5 in the figure.

本図示例のロータリキルン3においては、内部に所定のセメントを供給した状態で、駆動装置及び動力伝達手段8(図3参照)を介してシェル2を所定速度で回転駆動させると、ローラ7に支持されたタイヤ5が支持座金4及び支持ローラ9を介して一緒に回転駆動される。この場合、支持ローラ9はタイヤ5の内面に対し僅かに転動するが、支持ローラ9とタイヤ5とは線接触であるため、支持ローラ9とタイヤ5の相対摩擦力が低減し、むしり取りによる損耗が防止される。   In the rotary kiln 3 of the illustrated example, when the shell 2 is rotationally driven at a predetermined speed via the driving device and the power transmission means 8 (see FIG. 3) with a predetermined cement supplied therein, the roller 7 The supported tire 5 is rotationally driven together via the support washer 4 and the support roller 9. In this case, the support roller 9 rolls slightly with respect to the inner surface of the tire 5. However, since the support roller 9 and the tire 5 are in line contact with each other, the relative frictional force between the support roller 9 and the tire 5 is reduced, and the peeling is performed. Wear due to is prevented.

なお、本発明のロータリキルンは、上記した実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。   It should be noted that the rotary kiln of the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention.
