Description

The present invention relates to an asphalt concrete heat-insulating box, and more specifically, it accommodates asphalt concrete coming out of an asphalt concrete manufacturing device, and is capable of maintaining a constant temperature of the asphalt concrete until it is transported to a road construction site and discharged. Regarding asphalt concrete thermal insulation box.

Generally, asphalt concrete used for road paving is a black solid or semi-solid substance whose main component is hydrocarbon, with a solid component called asphaltin dispersed in an oil phase component called martin. be.

Depending on the type of asphalt concrete, it is used for road packaging and airport packaging, and it is also used for waterproofing in the pavement or construction fields.

In particular, asphalt, which is mainly used for road paving and airport paving, is mixed with aggregates such as sand, stone powder, crushed stone, and gravel, and is called asphalt concrete.

When such asphalt concrete is transported from a manufacturing plant to a road construction site, it can be transported by a separate asphalt concrete storage device that can transport the asphalt concrete while maintaining its temperature in order to maintain the quality of the asphalt concrete.

As a mobile asphalt concrete storage device that can store and move asphalt concrete in this way, Korean registered utility model No. 20-0454650 (mobile asphalt concrete storage device, hereinafter referred to as "prior art") is disclosed. .

The above-mentioned conventional technology includes a loading section that has an opening formed on the upper side, a switch that opens and closes the opening, and a storage section formed inside to store asphalt concrete; and a heater provided on one side of the loading section. a channel extending from the heater section and communicating with the storage section; a blower that supplies heat generated in the heater section to the storage section via the flow path; a blower formed on the lower side of the loading section; an asphalt concrete discharge section that discharges the asphalt concrete in the storage section through a discharge port; a first sensor that detects the temperature of the asphalt concrete in the storage section; a first sensor that detects the temperature of the asphalt concrete discharged through the discharge port; a second sensor provided at the tip of the discharge port for detection; and a preset temperature of the asphalt concrete to be discharged by comparing the detected values of the first and second sensors and compensating for the difference. a control unit that controls the heater unit so that the heater unit generates further heat to maintain the asphalt concrete at a constant temperature, and the asphalt concrete is easily transported to the construction site while maintaining the asphalt concrete at a constant temperature. The purpose of the present invention is to provide a mobile asphalt concrete storage device capable of maintaining the temperature of the discharged asphalt concrete at a temperature suitable for construction even when the stored asphalt concrete is discharged for construction. .

However, the above conventional technology has a structure in which a flow path is formed in the loading section that accommodates the asphalt concrete and heat generated by the heater section is supplied to the flow path, so the structure of the loading section is very complicated. In addition, there is a problem in that the heater section must continue to operate in order to maintain the temperature of the asphalt concrete.

In addition, even if heat is supplied to the asphalt concrete inside the storage section through the heater section, the heat is only transmitted to the outside part of the storage section and is not sufficiently transmitted to the inside. There is a problem that it is difficult to maintain the appropriate temperature of asphalt concrete.

Furthermore, even if heat is successfully transferred to the asphalt concrete through the heater section, if excessive heat is transferred into the storage section and the temperature of the asphalt concrete exceeds the appropriate temperature, the asphalt concrete will be discharged to the asphalt concrete discharge section. There is a problem in that the temperature is too high and AP flows down from the aggregate, causing a desorption phenomenon.

Therefore, in asphalt concrete storage equipment for storing and transporting asphalt concrete, even with a simple structure, the asphalt concrete thermal insulation box can store and transport asphalt concrete while maintaining the appropriate temperature from an asphalt concrete manufacturing factory to a road construction site. The current situation is that there is a need for the development of

There is also a need to improve the structure of the opening/closing device that opens and closes the lid of the asphalt concrete insulation box and the sealing device that seals the lid so that they can be easily operated.
