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、公開特許公報の特開平７−２１６８１７号にてのアスファルト加熱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熱気管が異常高温度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ので、タンクからアスファルトを取り出して、タンクの外部に加熱装置を設置して加熱する事により安全に容易に運搬する事を可能にする必要がある。 The present invention relates to a conventional system for heating asphalt stored in a tank of an asphalt tank lorry. In the asphalt heating system disclosed in Japanese Patent Application Laid-Open No. 7-216817, a small amount of asphalt is heated from the asphalt. The hot air pipes on the top are at an abnormally high temperature, and there is a danger of flaming and exploding the asphalt. A small amount of asphalt cannot be transported, so remove the asphalt from the tank and heat it by installing a heating device outside the tank. It is necessary to enable safe and easy transportation.

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外部に取り出し、外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様にするので、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運搬する事が可能となる。 Since the present invention takes out the asphalt stored in the tank of the asphalt tank lorry to the outside even during transportation, heats it with a heating device installed outside, sets it to a constant temperature, and returns it to the tank. Even with a small amount of asphalt, there is no danger of a fire in the tank, and it is possible to prevent the occurrence of an accident, and it is possible to safely transport even a small amount of asphalt during cold weather.

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、外部に取り出して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、少量のアスファルトでも加熱して容易に運搬して排出する事が出来る。 The present invention is safe because it is structured to take out the asphalt stored in the tank of the asphalt tank lorry to the outside and set it to a constant temperature by heating it with a heating device and returning it to the tank. Even small amounts of asphalt can be easily transported and discharged by heating.

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様に、外部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、一定の温度のアスファルトを安全に運搬する事が出来る。 Asphalt stored in the tank of the asphalt tank lorry is heated by installing an external heating device so that it can be safely heated even during transportation. Thus, it is possible to safely transport asphalt at a certain temperature.

図面を参照し説明します。図１に示す様に、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の前部下面に設けたアスファルト吸入用窪み（９）から吸入パイプ（６）を通して、アスファルト油圧式ポンプ（５）にて吸引されて送出パイプ（７）から加熱装置に送出されて、石油バーナー（８）に拠って一定の温度にアスファルトが加熱されて、アスファルト貯蔵タンク（１）の後方内部に注入される事により、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、貯蔵タンク内注入パイプ（１１）の中間部に切換バルブ（５４）を設置して必要に応じて直接外部に排出したい場合はタンクの外部に設けた切換バルブ操作ハンドル（５８）によって排出する事も出来る、そして必要に応じて切換バルブ操作ハンドル（５８）によってタンクの内部と外部に加熱されたアスファルトを放出する事が自由に出来る。 Explain with reference to drawings. As shown in FIG. 1, the asphalt stored in the tank of the asphalt tank lorry is transferred to the asphalt hydraulic pump (5) from the asphalt suction recess (9) provided on the lower front surface of the tank through the suction pipe (6). The asphalt is sucked and sent from the delivery pipe (7) to the heating device, heated to a constant temperature by the oil burner (8), and injected into the rear interior of the asphalt storage tank (1). Asphalt can circulate in the asphalt storage tank (1) and can be kept at a constant temperature, and a switching valve (54) is installed in the middle of the injection pipe (11) in the storage tank as required. If you want to discharge directly to the outside, you can also use the switching valve operation handle (58) provided outside the tank, and switch as necessary. Lube operating handle (58) by can freely to release the internal and external to the heated asphalt tank.

図２は加熱装置の正面を表示したものであり、アスファルト油圧式ポンプ（５）にて吸引されて送出パイプ（７）から送れたアスファルトはフランジ（１５、１６）にて連結管（１９）で連結された加熱装置内の加熱用パイプ内にて石油バーナー（８）に拠って一定の温度に加熱されて、アスファルト貯蔵タンク（１）の後方上面に注入する為の貯蔵タンク内注入パイプ（１１）のフランジ（１７、１８）にて連結管（２０）で連結されて加熱されたアスファルトをアスファルト貯蔵タンク（１）内に送出する。 FIG. 2 shows the front of the heating device. The asphalt sucked by the asphalt hydraulic pump (5) and sent from the delivery pipe (7) is connected to the connecting pipe (19) by flanges (15, 16). An in-storage tank injection pipe (11) which is heated to a certain temperature by a petroleum burner (8) in a heating pipe in a connected heating device and is injected into the rear upper surface of the asphalt storage tank (1). The asphalt heated by the connecting pipe (20) at the flanges (17, 18) is sent into the asphalt storage tank (1).

図３は加熱装置内の加熱用パイプの構造を斜視図にしたものであり、加熱パイプ（３８、４０、４２、４４、４６、４８、５０、５２）の掃除が容易に出来る様に両端にキャップ（２２、２３、２４、２５、２６、２７、２８、２９、３０、３１、３２、３３、３４、３５、３６、３７、）を設置して保守、点検も可能にしている。 FIG. 3 is a perspective view of the structure of the heating pipe in the heating device, and the heating pipes (38, 40, 42, 44, 46, 48, 50, 52) are arranged at both ends so that the cleaning can be easily performed. Caps (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37) are installed to enable maintenance and inspection.

アスファルトをアスファルトタンクローリーによって運搬するには、タンク内に貯蔵されたアスファルトが硬化しない様にする事が最重要課題であり、本発明に拠って安全で且つ確実な温度管理が可能となり少量のアスファルトでも容易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 with an asphalt tank lorry, it is most important to prevent the asphalt stored in the tank from hardening, and according to the present invention, safe and reliable temperature control is possible, and even a small amount of asphalt can be used. It can be easily transported to remote locations, and its utility value is recognized.
