Description

Asphalt transfer method

The present invention relates to a method for transferring bitumen, which is a transfer method for transferring to a tank truck (tank Lorry or tank truck) while maintaining the pitch at a high temperature from the asphalt storage tank. In particular, it relates to a small area in an asphalt storage tank, and only efficiently and quickly heats the asphalt of the small area, and then transfers the small area of the asphalt to the storage tank to reduce the amount of fuel required for heating. The method of transferring asphalt.

The asphalt is usually kept at a high temperature before and after 150 ° C to make it liquid, and the liquid is transferred by a tank truck. When the bitumen is transferred to an asphalt tank truck, the method as shown in Fig. 4 is employed in the prior art.

That is, as shown in Fig. 4, when the asphalt is to be transferred to the tank truck, the asphalt is heated in the asphalt tank 100 before and after being heated to 150 ° C and stored, and then passed through the conduit 102 and then held by the transfer pump P101. The pitch at the above temperature is transferred to the tank truck 103.

However, the method must heat and heat the asphalt in the asphalt storage tank 100 at any time to a high temperature before and after 150 ° C, so it is necessary to use the equivalent The amount of fuel required for the above heating and insulation is very wasteful.

It is an object of the present invention to provide a method for transferring bitumen which is used to improve the disadvantages of the prior art described above, which is to provide a small area in the bitumen tank when the bitumen is transferred from the bitumen tank to the tank truck, and It is only efficient and rapid to heat the bitumen in the small area, and then transfer the bitumen in the small area to the tank truck to reduce the transfer method of the bitumen corresponding to the amount of fuel used for heating.

In order to solve the foregoing problems, a method for transferring asphalt from a bitumen storage tank to a tank truck according to the present invention is characterized in that a small area is set in the asphalt storage tank, and only the small area is efficiently and rapidly The bitumen is heated, and the bitumen in the small area is transferred to the tank truck to reduce the amount of fuel required for heating.

The above invention is to provide a small area in the asphalt storage tank. Moreover, the pitch of the small area is heated only efficiently and quickly, and the bitumen of the small area is transferred to the tank truck to reduce the amount of fuel required for heating.

Fig. 1 is an explanatory view showing a transfer method disclosed in the present invention.

Fig. 2 is an explanatory view showing a modified column of the transfer method disclosed in the present invention.

Fig. 3 is a perspective view showing a specific example of a small area in the first and second figures.

Fig. 4 is an explanatory diagram of a conventional transfer method.

The method of transferring the bitumen disclosed in the present invention will be described in detail using Fig. 1 . In the first drawing, the reference numeral 1 is an asphalt storage tank, 2 is a duct, 3 is a transfer pump, 4 is a tank truck, 5 is a small area, 6 is a heating pump, and 7 is a heater.

The asphalt storage tank 1 stores asphalt which is heated at a low temperature to about 80 °C. The pitch in the small area 5 is circulated in the direction of the arrow by the heating pump 6 via the conduit 2, and is heated by the heater 7 efficiently and rapidly to a temperature of about 150 °C.

The pitch in the heated small area 5 is transferred to the sump cart 4 via the duct 2 by the action of the transfer pump 3. By this, only transfer small The pitch of the zone 5 to the tank truck 4 reduces the amount of fuel required for heating.

Fig. 2 is a modification of the transfer process of Fig. 1 which is further provided with a controller 8, a transfer pump starter 9, a pressure switch 10, a temperature sensor 11, and a heater 7, which is heated The pump 6, the pressure switch 10, and the temperature sensor 11 are coupled to the controller 8 for controlling the flow rate of the heating pump 6 or the temperature adjustment by the heater, and the transfer pump 3 while observing the temperature and pressure of the asphalt. Manipulation.

In the first and second figures, the small area 5 in the asphalt storage tank 1 is, for example, a "heat-efficient fuel oil storage tank" described in JP-A-2002-308399.

A small area 5 described in Japanese Laid-Open Patent Publication No. 2002-308399 is proposed in which a box-shaped small area 5 is provided in the asphalt storage tank 1 to cover the suction main pipe 12, and a partition 13 is further provided in the small area 5. . The pitch before and after heating to 80 ° C collides with the bell inlet sleeve 14 of the suction main pipe 12 toward the horizontal plate 17 of the top plate 16 or the partition plate 13 to cause turbulent flow for mixing, and is heated to 150 ° C by the heater 7 . When the heated pitch is discharged, it flows through the separator 13 from the hole 15 and is introduced into the small region 5, and at this point of time, the mixture is sufficiently mixed by turbulence and maintained at a temperature of 150 °C. The pitch before and after heating to 150 ° C is continuously discharged to the conduit 2.

[Industry Utilization]

Transferring bitumen from asphalt storage tank to storage disclosed in the present invention The method for transferring the asphalt of the tank truck is because a small area is provided in the asphalt storage tank, and the asphalt in the small area is heated only efficiently and quickly, and the asphalt in the small area is transferred to the storage tank, so that the reduction can be equivalent. The amount of fuel required to heat and its availability is very high in the asphalt industry.
