Description

[Detailed description of the invention] The present invention relates to a tank for storing powder and granular materials, which is partitioned into predetermined sizes so that the stored powder and granular materials can be metered and discharged. be.

In general, in tanks for storing powder and granular materials, if the inside of the tank is divided by partition plates and the capacity to be stored in the compartment is determined in advance, there is no need to weigh it each time it is discharged.
It will be very convenient.

However, in general, the installation of the partition plate that partitions the inside of the tank must be changed each time depending on the amount of partition desired by the user. If an attempt is made to provide a partition plate that partitions the air so that it can be accommodated, a problem arises in that depending on the coverage force of the inclined plate that leads to the air discharge section, the put space becomes large and the storage capacity decreases.

In view of the above-mentioned problems, the present invention has been developed to improve the air discharge section.

Even if it is a standard tank with a predetermined mounting position, the inside of the tank can be divided into predetermined sizes without increasing the installation space or changing the structure, and the powder and granules inside the tank can be metered and discharged. The purpose of the present invention is to provide a funeral tank for storing powder and granular materials.

Below, an embodiment of the present invention will be explained with reference to the drawings.Tank 1
is composed of front and rear hemispherical parts 2, 2 and a cylindrical part 3 in the center, and the powder and granules in the tank 1 are distributed to the outside of the tank 1 in three places at equal intervals at the center of the tank and in front and behind it. Air discharge portions 4.4', 4' are provided for discharging air.

Since the air discharge parts 4, 4', and 4' have the same structure, one of the air discharge parts 4 will be explained. Funnel-shaped campus 6 stretched over the opening on the top surface
An air pipe 8 connected to a compressor (not shown) is connected to an air chamber 7 defined by a canvas 6 and a lid 5.

Therefore, the high pressure air that has flowed into the air chamber 7 passes through the campus 6 and flows into the tank 1, so the campus 6
The upper particulate material is fluidized and discharged to the outside of the tank 1 through a discharge pipe 9 opened at the center of the bottom of the canvas 6.

At the inner bottom of the tank 1 between the air discharge parts 4 and 4', there is provided a chevron-shaped sliding part 1F formed by a pair of front and rear inclined plates 10 and 10', which are partially funnel-shaped. The powder and granular material on the upper part of 1 can be allowed to flow down by gravity and guided to the air discharge parts 4, 4'.

Further, at the inner bottom of the tank 1 between the air discharge portions 4', 1, there is also provided a sliding portion 11' similar to that described above, which is formed by a pair of front and rear inclined plates 1σ', 10''.

The front and rear inclined plates 10' and 16' which guide the powder and granules of the tank 1 to the central air discharge part 4' have chevron-shaped sliding parts 11°11'.
Extension pieces 12 , 12 extending diagonally upward from the top of the
' is provided, and the upper end of this extension piece 12.12' extends inside the tank 1 into the central compartment 14' and the front and rear compartments 14, 171.
It is connected to the lower part of a vertical partition plate 13 and 13' that partitions into 13 and 13'.

The front and rear compartments 14, 14' divided by the partition plates 13° 13' are divided into small compartments, and the central compartment 1
4' is approximately twice the size of each compartment 14.1/.

Note that 15, 15' and 1 da are the compartments 14 and 14'.

This is a manhole provided at the top of 14'.

The present invention has the above-described configuration, and when storing powder and granular material in the tank 1, each manhole 15, 15'.

A desired amount of powder can be stored in each of the compartments 14, 14', and 14' from the tank 1.When discharging the powder and granules in the tank 1, high-pressure air from the compressor is passed through the air pipe 8 into the air chamber 7. When the flow is caused to flow into the tank 1 through the campus 6, the extension piece 12.12
The powder and granules flowing down along the slide parts 11 and 11 and guided to the air discharge parts 4, 4', and 4' are fluidized on the surface of the canvas 6, and the fluidized powder and granules are transferred to the discharge pipe. 9 and is discharged to the outside of the tank 1.

By the way, when storing powder and granules in the tank 1, for example, 1 ton of powder and granules are stored in each of the front and rear compartments 14', and 2 tons of powder and granules are stored in the central compartment 14'. By weighing and storing each, if you want to discharge 1 ton of powder or granules at a predetermined location, you only need to discharge from one of the front and rear compartments 14, 14', and if you want to discharge 2 tons, you only need to discharge from one of the central compartments. Only the chamber 14' needs to be discharged, and if it is desired to discharge an additional 3 tons, there is no need to weigh the powder at the time of discharge if the powder and granules in the center and one of the front and rear chambers are discharged.

As described above, the present invention provides three air discharge sections at approximately equal intervals at the center and front and back of the tank at the bottom of the tank, and a pair of front and rear sloped plates in the shape of a mountain at the bottom of the tank between the air discharge sections. At the same time, the front and rear inclined plates that guide the powder and granular material in the tank to the central air discharge part are extended diagonally upward from the top, and the extended ends are vertical plates that divide the inside of the tank into compartments at the center and before and after it. Since the central compartment is approximately twice as large as the front and rear compartments, it is possible to weigh and discharge, for example, 1 ton, 2 ton, or 3 ton depending on the selection of the compartments.

In addition, when installing the partition plate, there is no problem of increasing the get space inside the tank and reducing the storage capacity, and the installation is very easy, and the powder and granules inside the tank can be reliably guided to each air discharge part. .

Furthermore, since the tank center compartment is approximately twice the size of the front and rear compartments, stable transportation is possible when this tank is mounted on a car and transported.
