Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple silo for storing asphalt mixture.

[0002]

2. Description of the Related Art Conventionally, an asphalt mixture storage silo used for road pavement or the like is provided adjacent to a plant body 21 of asphalt mixture by a skip elevator 22 as shown in FIG. In general, it is in the shape of a tank. According to this, the asphalt mixture produced in the plant body 21 is sequentially charged into the mixture silo 20 by the skip elevator 22 to retain and accumulate it at a predetermined temperature, and at the required amount It is discharged from the lower part of the mix silo and loaded onto a truck for shipment.

However, since the conventional silo for accumulating asphalt mixture of this kind is an extremely large-scale device, it takes at least three months or more from the foundation work to its completion, and it takes a long time for construction and the equipment cost is very high. There was a problem that it would be expensive. In addition, a large amount of asphalt mixture is used for concentrated pavement work, but in that case, the production of asphalt mixture cannot exceed the capacity of the silo, so it is necessary to keep many trucks for shipping on standby. There was a problem. Furthermore, it is not possible to throw in mixes that have been returned due to construction being canceled or interrupted due to sudden rainfall, etc. There was also a problem that it had to be disposed of, resulting in waste of resources.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and has a simple structure and a construction period of 1 to 1.
It only takes 2 days, and it can be installed easily and inexpensively in any place, and it can ship the required amount of mix material at any time, eliminating waiting time for trucks and greatly reducing the number of units used. Further, the purpose of the present invention is to provide a simple silo for storing asphalt mixture, which can receive returned mixture and store it again, and can also effectively utilize by recycling resources.

[0005]

The simple composite material silo of the present invention, which has been made to solve the above-mentioned problems, is a discharge port in which the front surface of a box-shaped silo body made of a heat insulating panel can be opened and closed by a front lid. In addition to the above, the upper surface of the silo main body is formed as an input port that can be opened and closed by an upper lid.

[0006]

The present invention will now be described in detail with reference to the illustrated embodiments. In the figure, 1 is, for example, width 400 cm, depth 500 cm,
This is a silo main body for accumulating asphalt mixture having a height of about 350 cm, and the silo main body 1 is assembled in a box shape by a plurality of panel bodies 2 having excellent heat insulating properties with an opening extending from the front surface to the upper surface. Further, as shown in FIG. 2, the panel body 2 is a plate-like member in which a heat insulating material 4 such as glass wool is filled between an inner surface side steel plate 3a and an outer surface side steel plate 3b, and has an arbitrary shape and capacity. It can be assembled to the silo body 1. The front opening of the silo body 1 serves as a discharge opening 1a, and the top opening serves as a charging opening 1b. The discharge opening 1a is pivoted about its bottom so as to be substantially flush with the bottom of the silo body 1. Is opened to an opening angle of about 90 degrees or more and can be opened and closed by a front lid 5 made of the same material as the panel body 2 which substitutes for the entrance / exit footboard, and the insertion opening 1b is at the rear portion. The front lid 5 and the upper lid 6 are made of the same material as the front lid 5 and can be opened and closed freely. When the front lid 5 and the upper lid 6 are closed, the inside is completely sealed and an excellent greenhouse can be secured. It is configured as follows.

In the embodiment, the opening and closing of the upper lid 6 is configured to be freely rotated by the electric winch 7. However, when the power supply cannot be secured due to the installation location, a manual winch or the like is used. It may be rotatable, and the opening / closing operation of the front lid 5 may be similarly configured. Further, a panel heater 8 can be built in the steel plate side on the inner surface side of the panel body 2 which constitutes the silo body 1 for the purpose of ensuring heat retention in winter, etc., and oxidation deterioration during storage of the mixture is prevented. In order to prevent this, a deterioration prevention device 9 due to an inert gas such as CO ₂ may be provided, and when the silo body 1 is small, it may be movable as a trolley, and further, the discharge port 1a.
The opening direction of the front lid 5 and the upper lid 6 for opening and closing the inlet 1b is not limited to the direction of the above-described embodiment, and the front lid 5 and the upper lid 6 may be connected in series and opened and closed at the same time.

[0008]

[Operation] Unlike the conventional composite material silo that is a large-scale device, this structure can be installed by assembling the panel body 2, so the construction period is only 1 to 2 days. In addition, the construction cost can be reduced to 10% or less of the conventional one, and after the construction is completed, it can be disassembled and repeatedly used at the next site, so that an excellent economic effect is exhibited. Moreover, the installation location is not limited,
Since it can be arbitrarily constructed near the pavement construction site, the asphalt mixture can be smoothly supplied to the site.

Next, the storage procedure of the asphalt mixture when such a simple mixture silo is used will be described with reference to FIG. 4. The asphalt mixture formed by the plant body 21 is a shovel car 23 or the like. Is sequentially carried to the silo main body 1 and stocked, and is taken out in a required amount and supplied to the site. At this time, since the upper portion of the silo body 1 is opened as the charging port 1b, it can be accurately and easily charged into the silo body 1 from the shovel car 23 or the like, and the front part of the silo body 1 is opened as the discharging port 1a. Can be taken out easily because it has
Further, the loading port 1b can be widely opened to easily carry in and out the mixture, and at other times, the front cover 5 and the upper cover 6 are closed to store the mixture while keeping the mixture at a predetermined temperature. Becomes

Then, according to the present invention, the plant main body 2
Since the composite material molded in 1 can be sequentially carried to the silo and stocked, continuous operation can be continued on the plant body 21 side,
It is possible to continue production efficiently with low fuel consumption. Further, since the mixed material can be taken out sequentially from the stock portion stored in the silo main body 1, it is not necessary to wait a lot of shipping trucks as in the conventional case. Furthermore,
In the present invention, the return composite material, which has conventionally been forced to be disposed of, can be reused after being charged again to accumulate and store it in a heat-retaining state and to reuse it at a later date.

When 90 tons of a new asphalt mixture produced in the plant itself was stored in the silo of the present invention for 24 hours, it was initially 165 ° C., but at the time of shipment it was 154 ° C. and the temperature drop was only 11 ° C. Therefore, it was confirmed that the function of the silo could be fully demonstrated. Further, when 15 tons of the return material from the construction site was put into the silo and shipped the next day, the temperature of the material was 140 ° C. This is considered to be a total temperature decrease of 25 ° C, which is about 15 ° C during transportation of the mixture and about 10 ° C during storage in the silo. Although it is possible to ship at this temperature, it is even more effective if it is loaded into a transport vehicle so as to be sandwiched between new materials set at a higher temperature. Then, as a result of heat conduction from the new material during the transportation time and mixing and stirring by the paving machine, it was confirmed that the pavement temperature was appropriate and that the pavement machine could be sufficiently used.

[0012]

As is apparent from the above description, the present invention has a simple structure, a short construction period of 1 to 2 days, and can be easily and inexpensively installed in any place. Since we can ship the required amount of mix material at any time, we can eliminate the waiting time of the truck and achieve a significant reduction in the number of units used, and it is also possible to accept the return mix material and store it again and save resources. There are various advantages such as effective utilization by recycling. Therefore, the present invention is a simple silo for asphalt mixture storage that eliminates the problems in the conventional asphalt mixture treatment, and it greatly contributes to industrial development.
