Description

[Detailed description of the invention] [Industrial application field] The present invention is suitable for storing various powders, gravel, etc., such as aggregate silos for storing aggregate for producing asphalt mixture in an asphalt plant. This relates to storage silos.

[Prior art] The above-mentioned aggregate silos were generally so-called corrugated silos constructed with corrugated wall materials, but as urban areas expand and urban redevelopment progresses, narrow and overflowing When constructing a large-capacity aggregate silo in a location with a large capacity, a high-rise structure is inevitably desired, and corrugated silos have problems in terms of strength and the noise generated may affect the surrounding environment. be.

In order to eliminate such disadvantages of corrugated silos, in recent years, silos constructed with reinforced concrete wall materials have been increasingly adopted.

Reference numeral 1 in FIG. 2 indicates an example of such a silo.

This silo 1 is erected on the ground L, and includes a storage section 3 consisting of a cylindrical wall 2 made of concrete,
It consists of a take-out part 4 which is provided directly under the storage part 3 and which also serves as a foundation, which is provided integrally with the cylindrical wall body 2. The aggregate W in the storage section 3 is received by the hopper 5, and a fixed amount of the aggregate W is transferred onto a belt conveyor 7 installed below the hopper 5 by a cutting feeder 6 attached to the lower part of the hopper 5. It is designed to be discharged. The belt conveyor 7 transports the aggregate W to a predetermined facility.

[Problems to be solved by the invention] However, according to the aggregate silo 1 described above, the take-out section 4 that receives the weight (load) of the aggregate W in the storage section 3, the hopper 5 equipped with the take-out feeder 6, and the belt conveyor 7 Since there is a space 8 for arranging the storage unit 3, there is a limit to increasing the capacity of the storage unit 3, that is, making it high-rise, taking into account the lack of strength. Therefore, in order to achieve further high-rise construction, it is possible to improve the strength of the take-out part 4, but to do so, the take-out part 4 must be constructed to a corresponding size (height), and the As a result, the construction material, reinforced concrete, and the construction cost will increase.

[Means for Solving the Problems] The present invention has been made to solve the above problems, and includes a storage section made of a cylindrical body, the bottom of which is installed on a foundation such as the ground. A storage outlet is formed in the lower part of the side wall of the storage section, a pit is provided on the base facing the storage outlet, and the stored items discharged from the storage outlet are placed in the pit. It is characterized by the fact that it is equipped with a hotspa to receive the food.

[Function] According to the storage silo of the present invention, the stored material in the storage section is dropped into the hopper in the pit from the stored material discharge port at the lower part of the side wall, and the stored material is carried out from the hopper.

The storage section is built upright on the base with the bottom resting on the ground, etc., so the load of the stored items in the storage section is directly received by the foundation, reducing the load on the bottom of the storage section. The structure is such that Therefore, there is no need to particularly strengthen the bottom of the storage section, so when constructing this storage section, it is possible to reduce the amount of materials and shorten the construction period.
By making the storage section high-rise, it becomes possible to increase the amount of storage.

In addition, the hopper does not receive the load of all the stored items in the storage section, but only receives a small amount of load from the stored items discharged laterally from the stored items discharge port into the hopper. The durability of the material is improved.

[Example] Hereinafter, an example in which the present invention is applied to the aggregate silo will be described with reference to FIG.

Reference numeral 10 in the figure is a storage section in which aggregate W is stored, and this storage section 10 has a cylindrical or polygonal cylindrical shape consisting of a floor section 11a and side walls 11b that are erected on the ground (base) L. It is constructed by the wall body 11 of. An opening 11c is formed above the wall 11, and the aggregate W is introduced into the storage section 10 through the opening 11c and stored therein.

The wall 11 is made of reinforced concrete, and an aggregate discharge port (stored material discharge port) 12 leading to the ground L is formed at the lower part of the side wall 11b of the wall body 11.

and a position facing the aggregate discharge port 12 of the ground L,
That is, on the ground L on the side and below the aggregate discharge port 12 on the external side of the side wall 11b, the wall 11
A pit 13 with a rectangular cross section that is integrated with the floor portion 11a of the
A hopper 14 for receiving the aggregate W and a belt conveyor 15 are installed in the pit 13.

To be more specific, a step 16 is formed on the upper edge of the opening 13a of the pit 13, and a flange 14 forming the upper end of the hopper 14 is formed on the step 16.
The hopper 14 is installed in the pit 13 by engaging the hopper a. A cutting feeder 17 for discharging the aggregate W in the hopper 14 is attached to the lower end of the hopper 14. When the cutting feeder 17 is opened, the aggregate W is transferred to the belt conveyor 15.
It is designed to fall on top of. The belt conveyor 15 carries out the aggregate W in the front or rear direction on the drawing and sends it to a predetermined facility.

Further, the opening 13a of the pit 13 is made of aggregate W.
Grating 1 is a metal grating through which
8, and heavy machinery such as a bucket loader can run on this grating 18.

The aggregate W is always discharged from the aggregate discharge port 12 under its own weight pressure, and all of the discharged aggregate W falls into the hopper 14 within the range of the angle of repose. It's getting old. Therefore, in order to maintain this state, the sizes of the aggregate discharge port 12 and the hopper 14 are set in accordance with the flow state of the aggregate W.

In addition, 19 in FIG. 1 is an enclosure for protecting the aggregate W existing between the aggregate discharge port 12 and the hopper 14 from wind and rain, and 20 is a valve 21 for removing water accumulated in the storage section 10. This is a drainage hole that is opened and closed by the

According to the aggregate silo (storage silo) 22 configured as described above, as described above, the storage section 10
The aggregate W inputted from the opening 11c is discharged from the aggregate outlet 12 to the outside of the storage section 10 by its own weight and is dropped into the hopper 14.
4, the aggregate W is stored in the storage section 10.
The stored state is maintained.

When taking out the aggregate W, the cutting feeder 17 is opened and closed to drop the necessary amount onto the belt conveyor 15.

Furthermore, if the amount of aggregate W stored is too small to be discharged from the aggregate discharge port 12, that is, the aggregate W in a dead stock state below the broken line A in FIG. Then, the aggregate W is transported by the bucket loader that has entered the storage section 10 and is thrown into the hopper 14.

However, the lever aggregate silo 22 has a structure in which the side wall 11b is provided with an aggregate discharge port 12, and the load of the aggregate W stored in the storage section 10 is received by the one-layer floor section 11a that is in direct contact with the ground L. Therefore, it is possible to reduce the amount of materials required to construct the floor portion 11a and shorten the construction period. Further, the load of the aggregate W that the hopper 14 and the cutting feeder 17 receive is small, and their durability is improved.

Furthermore, since the storage section 10 is installed directly on the ground L, as is clear from the comparison with the conventional aggregate silo 1 shown in Fig. 2, if the height of the storage section 10 is the same, , the total height can be lowered, increasing safety, and if the height is kept the same, the storage capacity can be increased. That is, since the load of the aggregate W is directly received by the ground L, it is possible to realize a high rise.

Furthermore, since the aggregate W can be directly charged into the hopper 14 without charging the aggregate W into the storage section 10, problems such as malfunction of the device for charging the aggregate W into the storage section 10 can be avoided. Another advantage is that even if this occurs, there is no risk of the asphalt plant being shut down.

In addition, the drainage hole 20 formed in the floor part 11a of the wall body 11 can be made large because it does not have much influence on the strength of the floor part 11a. It is possible to reduce the water content of W, and to save energy when heating the aggregate W in a later step.

[Effects of the invention] As explained above, according to the storage silo of the invention, the storage section made of a cylindrical body is erected on the base such as the ground with the bottom part installed on the base, A stored material discharge port is formed in the lower part of the side wall of the storage section, a pit is provided on the base facing the storage section discharge port, and a hopper is installed in the pit to receive the stored material discharged from the stored material discharge port. Since it is characterized by the following effects, the following effects are achieved.

The storage section is installed upright on the foundation with the bottom part installed on the foundation such as the ground.
The load of the stored items in the storage section is directly received by the foundation,
Since the structure reduces the load applied to the bottom of the storage, there is no need to particularly strengthen the bottom of the storage, and as a result, when constructing the storage,
In addition to reducing the amount of materials and construction period, the storage capacity can be increased by making the storage section higher-rise.

The hopper does not receive the entire load of the stored items in the storage section, but only receives a small amount of load from the stored items discharged laterally from the stored items discharge port into the hopper, which increases the durability of the hopper. will improve.
