Description

Special vehicle for transportation of ascon heat insulation capable of inject inert gas}

The present invention relates to a special vehicle for transporting ascon thermal insulation capable of injecting inert gas, and more particularly, by injecting inert gas into an ascon thermal insulation box containing ascon to transport the ascon to a road pavement site and maintain it at a constant temperature until discharged. At the same time, it relates to a specially equipped vehicle for transporting ascon insulation that can prevent aging and oxidation of ascon and change in physical properties.

In general, asphalt concrete (hereinafter referred to as 'ascon') used for road pavement is a black solid or semi-solid material, the main component of which is hydrocarbon, and a solid component called asphaltene is dispersed in an oil component called martin.

These ascons are divided into road pavement and airport pavement depending on their type, or are used for waterproofing in the pavement or construction field.

In particular, asphalt, which is mainly used for road paving or airport paving, etc., is used by mixing aggregates such as sand, stone powder, crushed stone, gravel, etc., which is called ascon.

Such asphalt concrete can be transported by a separate asphalt concrete storage device that can be transported while maintaining the temperature of asphalt concrete in order to maintain the quality of asphalt concrete in transport from the manufacturing plant to the road pavement site.

As such a movable asphalt concrete storage device capable of storing and moving ascon, Republic of Korea Utility Model Registration No. 20-0454650 (movable asphalt storage device, hereinafter referred to as 'prior art') is disclosed.

The prior art includes a heater unit installed on one side of the loading unit; a flow path extending from the heater unit and communicating with the receiving unit; a blower supplying the heat generated in the heater unit to the receiving unit through the flow path; Ascon discharge unit for discharging the asphalt concrete in the accommodating unit through a discharge port formed on the lower side of the loading unit; A first sensor for sensing the temperature of the asphalt concrete in the receiving unit; A second sensor provided at an end of the outlet to detect the temperature of the asphalt concrete discharged through the outlet; And a control unit that compares the detected values of the first and second sensors and controls the heater unit so that the heater unit further generates additional heat for maintaining the temperature of the asphalt concrete discharged by compensating for the difference at a predetermined temperature; A portable ascon storage device that can be easily transported to the construction site while maintaining the ascon at a constant temperature, and can maintain the temperature of the discharged ascon at an appropriate temperature for construction even if the received ascon is discharged for construction. Its purpose is to provide

However, the prior art has a structure in which a flow path is formed in the loading unit for accommodating the asphalt concrete to supply heat generated through the heater unit to the flow path, so that the structure of the loading unit is very complicated, and in order to continuously maintain the temperature of the asphalt concrete There is a problem in that the heater unit must be continuously operated.

In addition, even if heat is supplied to the ascon in the accommodating unit through the heater unit, the heat is transferred only to the outside of the accommodating unit and is not sufficiently transmitted to the inside, so it is difficult for the heat to affect the ascon disposed inside the accommodating unit. There is a problem that it is difficult to maintain an appropriate temperature.

In addition, even if heat is transferred to the asphalt concrete well through the heater part, if too much heat is transferred to the receiving part and the temperature of the asphalt concrete exceeds the proper temperature, the temperature of the asphalt concrete discharged to the asphalt discharge part is too high, so AP flows down to the aggregate and desorbs. There are problems that can cause the symptoms.

In addition, in the case of the prior art, there is a problem in that the ascon is aged and oxidized by the air present on the upper side of the ascon accommodated in the receiving unit, resulting in a change in physical properties and a decrease in the temperature of the ascon.

Therefore, in the asphalt storage device for storing and transporting ascon, even with a simple structure, it is possible to store and transport the asphalt while maintaining the temperature of the asphalt at an appropriate temperature from the asphalt manufacturing plant to the road pavement site, and the asphalt is aged and oxidized. There is a need to develop an asphalt concrete storage device and a transport vehicle capable of preventing physical properties from being changed.

The injection module 50 may be formed in the box body 21 .

The injection module 50 may be formed to pass through the outer box 211 and the inner box 213 of the box body 21 .

That is, the injection module 50 may be formed to penetrate from the outside of the outer box 211 to the inside of the inner box 213.

The injection module 50 may be formed anywhere on the sides of the box body 21 in four directions.

The injection module 50 may inject an inert gas into the inner box 213 .

The injection module 50 includes an injection pipe 51, an injection valve 53 formed at one end of the injection pipe 51, an on-off valve 55 formed at the other end of the injection pipe 51, and an injection valve ( 53) may include a gas cylinder 57 provided on the side of the outer box 211 and a packing material 59 provided at one end and the other end of the injection pipe 51.

The injection pipe 51 may be formed to pass through the outer box 211 and the inner box 213 and be connected.

The injection tube 51 may be formed as a hollow tube inserted to penetrate between the outer box 211 and the inner box 213.

It is preferable to use the material.

An injection valve 53 may be provided at one end of the injection pipe 51 .

The injection valve 53 is coupled to one end of the injection pipe 51 and may be an automatic valve or a manual valve.

When the injection valve 53 is applied as a manual valve, a valve having a structure similar to a conventionally used gas valve may be used, and when applied as an automatic valve, a solenoid valve may be used.

When the gas is injected into the opening/closing valve 55, the sealing member is pushed to the rear by the pressure of the injected gas, and a flow path through which the gas can flow is formed between the flow bracket and the injection pipe 51. The gas can be moved through the passage and injected into the inner box 213 .

Thereafter, when the injection valve 53 is closed and the injection of gas is stopped, the pressure due to the gas is lost inside the injection pipe 51, and as the pressure is lost, the sealing member returns to its original position by the pressing force of the spring. It is possible to seal the inside of the injection pipe 51 again.

In addition, as shown in FIG. 17, the one-way valve is formed of a passage bracket and a sealing member rotatably hinged to the passage bracket, so that the sealing member seals one end of the passage bracket at normal times, and when gas is injected, the gas It may be formed so that one end of the euro bracket is opened by allowing the sealing member to rotate backward by pressure.

In addition, any one-way valve that can be opened by gas pressure in one direction and closed by loss of pressure can be used.

Therefore, the opening/closing valve 55 is opened when pressure due to the injection of gas exists inside the injection pipe 51 so that the inert gas can be injected into the inner box 213 and the inside of the injection pipe 51 When the pressure is lost, it is closed to seal between the inner box 213 and the injection pipe 51, thereby preventing external air from entering the inner box 213.

As a result, the injection valve 53 and the opening/closing valve 55 double open and close both ends of the injection pipe 51 so that the injection pipe 51 is not opened except when the inert gas is injected, so that air enters the injection pipe ( 51) to prevent inflow into the inner box 213.

In addition, packing materials 59 may be provided at one end and the other end of the injection tube 51 .

That is, the packing material 59 includes the injection valve 53 provided at one end of the injection pipe 51, the contact surface of the injection pipe 51, and the on-off valve 55 provided at the other end of the injection pipe 51. It is provided on the contact surface of the injection pipe 51 to seal one end and the other end of the injection pipe 51 by packing.

Therefore, it is possible to block external air from being injected into the inner box 213 through the injection valve 53, the opening/closing valve 55, and the injection pipe 51.

An inert gas may be injected into the inner box 213 through the aforementioned injection module 50 .

The inert gas may be injected into the upper portion of the asphalt concrete loaded inside the inner box 213 to form an inert gas layer (B) on the upper portion of the asphalt concrete.

Here, as the inert gas, any one of helium, argon, krypton, radon, nitrogen, carbon dioxide, xenon, neon, and xenon may be selected and used.
