A thermal insulation silo on an asphalt pavement comprehensive maintenance vehicle

Abstract

The invention discloses a thermal insulation bin on a comprehensive bituminous pavement maintenance truck. The thermal insulation bin comprises a bin body (1), a thermal insulation layer (3), an infrared heating device (5), a discharge chute (6), a bin door (9), a fan and a spiral channel layer (2), wherein the discharge chute is arranged at the bottom of the bin body, the bin door is arranged at the upper part of the bin body, the thermal insulation layer is arranged outside the bin body, the infrared heating device is arranged at the lower part of the bin body, the spiral channel layer is arranged between the bin body and the thermal insulation layer, and an air inlet of the fan is arranged at the lower part of the bin body. The spiral channel layer can wrap the whole bin body, and heating flue gas passes through the spiral channel layer to heat whole mixed materials in the bin body in a circulating manner, so that the heating is uniform, and the heating efficiency is improved; the thermal insulation layer is arranged outside the spiral channel layer, and a thermal insulation medium is filled in the thermal insulation layer, thereby performing thermal insulation on the heated materials. The thermal insulation bin has the functions of heating and thermal insulation and can guarantee the quality of pavement maintenance.

Description

technical field [0001] The invention relates to an asphalt pavement maintenance vehicle, in particular to an insulating material bin on the asphalt pavement comprehensive maintenance vehicle. Background technique [0002] The structure of the existing maintenance vehicle thermal insulation silo is generally a layer of thermal insulation layer wrapped around the silo body, and the thermal insulation layer is filled with thermal insulation medium, which plays a role in thermal insulation of the heated materials. In the comprehensive maintenance construction of asphalt pavement, The temperature requirements for asphalt materials are very high. Even if they are stored in thermal insulation bins, it will inevitably cause heat loss. Therefore, in the process of road maintenance, thermal insulation bins and heating bins are often used in combination, which requires the asphalt in the thermal insulation bins Asphalt materials are transported to the heating bin, which not only increa...

[0002] The structure of the existing maintenance vehicle thermal insulation silo is generally a layer of thermal insulation layer wrapped around the silo body, and the thermal insulation layer is filled with thermal insulation medium, which plays a role in thermal insulation of the heated materials. In the comprehensive maintenance construction of asphalt pavement, The temperature requirements for asphalt materials are very high. Even if they are stored in thermal insulation bins, it will inevitably cause heat loss. Therefore, in the process of road maintenance, thermal insulation bins and heating bins are often used in combination, which requires the asphalt in the thermal insulation bins The asphalt material is transported to the heating bin, which not only increases the construction steps and reduces the work efficiency, but also generates heat loss during the transportation process, making it difficult for the asphalt material to reach the optimal bonding temperature during construction, and at the same time causing energy waste

At present, a silo with dual functions of heating and heat preservation has been designed, but it only has heating points at the bottom or both sides of the silo, and there is a problem of uneven heating, and the asphalt material cannot reach the optimal temperature, which will affect the construction quality
