Description

本発明は、アスファルトタンクローリーのタンク内に貯蔵したアスファルトを加熱する装置に関する物である。 The present invention relates to an apparatus for heating asphalt stored in a tank of an asphalt tank lorry.

アスファルトタンクローリーのタンク内に貯蔵されたアスファルトは運搬の途中で冷却してタンクからの排出が困難となるので、加熱して排出を容易にする。 The asphalt stored in the tank of the asphalt tank lorry is cooled during transportation and becomes difficult to discharge from the tank.

本発明は、アスファルトタンクローリーのタンク内に貯蔵されたアスファルトを加熱する従来のシステムでは、タンク内部の少量のアスファルトを加熱するとアスファルトより上に出ている加熱用パイプが異常高温になりアスファルトに引火爆発する危険があり少量のアスファルトの運搬は出来ない事と、直接加熱パイプに接しているアスファルトは沸点を超える高温になりガスが発生しその後に冷却し凝固しタンク内でカスとなり配管のつまりの原因になるので、カスの発生と品質の劣化を抑え短時間で加熱し安全に運搬する事を可能にする必要がある。 In the conventional system for heating asphalt stored in the tank of an asphalt tank lorry, when a small amount of asphalt inside the tank is heated, the heating pipe that is above the asphalt becomes abnormally hot and ignites the asphalt. Asphalt that is in direct contact with the heated pipe is heated to a temperature that exceeds the boiling point and generates gas, then cools and solidifies, causing sludge in the tank and causing clogging of the piping. Therefore, it is necessary to suppress the generation of debris and deterioration of quality and to enable safe transportation by heating in a short time.

Means for Solving the Invention

本発明は、アスファルトタンクローリーのタンク内に貯蔵されたアスファルトを運搬の途中でも、内部の加熱装置にて加熱して一定の温度に設定してタンク内に戻すようにするので、直接加熱パイプに接しているアスファルトは沸点を超える高温になる事無く安全に少量のアスファルトでもタンク内にて火災発生の危険性は無く事故の発生を防止する事が可能となり、寒冷の時期でも少量のアスファルトであっても劣化を防ぎ安全に運搬することが可能となる。 In the present invention, the asphalt stored in the tank of the asphalt tank lorry is heated by an internal heating device to be set at a constant temperature and returned to the tank even during the transportation, so that it directly contacts the heating pipe. The asphalt that can be used is a small amount of asphalt that can safely prevent a fire from occurring even in a small amount of asphalt without causing a high temperature exceeding the boiling point. It is possible to prevent deterioration and transport safely.

Effects of the present invention

本発明は、アスファルトタンクローリーのタンク内に貯蔵されたアスファルトを運搬の途中でも内部に設置した加熱装置にて加熱し一定の温度に設定してタンク内に戻す構造になっているので安全であり、加熱用パイプに接しているアスファルトが沸点を超える高温にはならないので、アスファルトが沸騰時に発生させるガスが無い事で、ガスがタンク内で冷却後に出来るカスの発生も抑えられ、加熱パイプに接しているアスファルトは循環しているので熱伝導率が良く従来の加熱時間より半分に短縮でき安全に少量のアスファルトでも火災発生の危険性はなく事故の発生を防止する事が可能となり、寒冷の時期でも少量のアスファルトであっても安全にカスの発生も抑え運搬する事が可能となる。 The present invention is safe because it is structured to return the asphalt stored in the tank of the asphalt tank lorry to a constant temperature by heating it with a heating device installed inside even during transportation, Since the asphalt in contact with the heating pipe does not reach a high temperature exceeding the boiling point, there is no gas to be generated when the asphalt boils. Since the asphalt is circulated, it has good thermal conductivity and can be shortened to half of the conventional heating time, and even with a small amount of asphalt, there is no risk of fire occurrence and it is possible to prevent the occurrence of accidents, even in cold weather Even a small amount of asphalt can be safely transported with less waste.

アスファルトタンクローリーのタンク内に貯蔵されたアスファルトを運搬の途中でも安全に加熱を可能にするように、貯蔵タンク内に加熱装置を設置して加熱し、一定の温度に設定して再びタンク内に戻す構造にして、アスファルトの劣化を抑え一定の温度で運搬する事が出来る。Asphalt stored in the tank of the asphalt tank truck is heated by installing a heating device in the storage tank so that it can be safely heated even during transportation, set to a constant temperature and returned to the tank again With a structure, it can be transported at a certain temperature while suppressing deterioration of asphalt.

図面を参照に説明します。図１に示すように、アスファルトタンクローリーのタンク内に貯蔵されたアスファルトをタンク内に設けた送出パイプ（１５）の吸引口（１４）から送出パイプ（１５）を通して、アスファルトポンプ（１６）にて吸引されて連結管（１８）から加熱装置に送出されて、石油バーナー（２）に拠って一定の温度にアスファルトが加熱されて、加熱装置排出口（１９）よりアスファルト貯蔵タンク（１）に注入されることにより、アスファルト貯蔵タンク（１）内にてアスファルトが循環して一定の温度に保つ事が可能となり、貯蔵タンク内のアスファルトポンプ（１６）と連結管（１８）の中間部に切替バルブ（１７）を設置して必要に応じてタンクの外部に排出する事も自由に出来る。 Explain with reference to drawings. As shown in FIG. 1, the asphalt stored in the tank of the asphalt tank lorry is sucked by the asphalt pump (16) from the suction port (14) of the delivery pipe (15) provided in the tank through the delivery pipe (15). The asphalt is sent from the connecting pipe (18) to the heating device, heated to a constant temperature by the oil burner (2), and injected into the asphalt storage tank (1) from the heating device discharge port (19). As a result, the asphalt circulates in the asphalt storage tank (1) and can be kept at a constant temperature, and a switching valve (16) is provided between the asphalt pump (16) and the connecting pipe (18) in the storage tank. 17) can be installed and discharged to the outside of the tank as needed.

図２は加熱装置の斜視を表示したものであり、アスファルトポンプ（１６）にて吸引されて連結管（１８）から送られたアスファルトは、加熱装置の外側パイプ（１２）内部と内側のパイプ（１３）外部の間（２６）にて、石油バーナー（２）によって内側パイプ（１３）の内部（２５）をバーナーで加熱することで一定の温度に加熱されて、アスファルト貯蔵タンク（１）内の加熱装置排出口（１９）より保温タンク（１）内に送出する。 FIG. 2 shows a perspective view of the heating device. The asphalt sucked by the asphalt pump (16) and sent from the connecting pipe (18) is divided into the inner pipe (12) and the inner pipe (12). 13) Between the outside (26), the inside (25) of the inner pipe (13) is heated with a burner by the oil burner (2) to be heated to a certain temperature, and the inside of the asphalt storage tank (1) It sends out into the heat insulation tank (1) from the heating device discharge port (19).

アスファルトをアスファルトタンクローリーに拠って運搬するには、タンク内に貯蔵されてアスファルトが硬化しないようにする事と加熱時に起こるアスファルトの劣化を防ぐ事、従来の加熱時間より半分に短縮する事が最重要課題であり、本発明に拠って安全であり確実な温度管理が可能となり少量のアスファルトでの用意に遠隔地まで運搬する事が可能となり利用価値が認められる。 In order to transport asphalt using an asphalt tank lorry, it is most important to prevent the asphalt from being cured by being stored in the tank, to prevent the asphalt from deteriorating during heating, and to shorten the heating time by half compared to the conventional heating time. This is a problem, and according to the present invention, safe and reliable temperature control is possible, and it can be transported to a remote place with a small amount of asphalt, and its utility value is recognized.
