2 to 8, a rectangular cell silo 10 having a lattice structure according to an embodiment of the present invention includes a hopper 100 and a discharge unit 200, and further includes a storage barrier 300, Cardox device (C) and RDM (R).

2, the rectangular cell silo 10 having a lattice-like structure includes a hopper 100 and a hopper 100 arranged in a lattice shape at the lower end of the hopper 100 to discharge the stored matter into the hopper 100 And a discharging unit 200 including a discharging port 240 for discharging the stored drops from the hopper 100. The discharging unit 200 is provided at an upper portion of the discharging port 240 to disperse the drops falling from the hopper 100 A dispersion part 210 for supporting the dispersing part 210 and a crossing part 220 supporting the dispersing part 210 to guide the discharge of the stored product and to connect the dispersion part 210 and the crossing partitions 220, And an inclined wall 230 that transmits the load 220 to the support wall 250 formed at the lower side.

As shown in FIGS. 1 and 2, the hopper 100 is a part for forming a space for storing a stored product in the silo, and a discharge part 200 through which the stored product is discharged is formed in the lower part of the hopper 100 do.

2, the discharge portion 200 may include a dispersing portion 210, a crossing barrier 220, a slanted wall 230, an outlet 240, and a support wall 250.

The dispersing unit 210 is configured such that the upper end thereof protrudes like a triangular cross section or the like to disperse the storage material descending from the hopper 100 into the discharge unit 200 to accumulate the stored material in the hopper 100, Thereby preventing the flow from being lowered.

As shown in FIGS. 2 and 3, the dispersion portion 210 can be supported by the crossing partition 220.

The cross barriers 220 are members for supporting the dispersing units 210 and may be configured such that the dispersing units 210 and the crossing barriers 220 do not directly transmit the load to the inclined walls 230, . ≪ / RTI >

As shown in FIGS. 2 and 3, the inclined wall 230 is a member that forms an optimized inclination angle to induce a natural discharge of the storage material descending from the hopper 100 to the discharge portion 200.

The inclined walls 230 do not directly support the load of the dispersing unit 210 and the crossing barrier 220 in terms of the distribution structure of the load but are connected to the crossing barrier 220 So that the dispersion part 210 and the cross barriers 220 can be transferred to the supporting wall body 250 formed at the lower side.

As shown in FIG. 5, the discharge port 240 is provided below the inclined wall 230 to discharge the stored matter in the silo to the outside. The discharge port 240 may be formed as a space formed between the RDM (R) main beam 231 protruding in the horizontal direction from both sides of the lower end of the inclined wall 230.

As shown in FIG. 2, a plurality of discharge units 200 may be installed in a lower portion of the hopper 100 of the silo.

The plurality of discharge units 200 may be installed on the entire cross section of the hopper 100. A plurality of discharge units 200 are provided on the entire cross section of the hopper 100 so that the cross sectional area of the lower portion of the silo does not decrease and the inner wall of the silo It is possible to prevent the deposit from adhering to the inclined wall 230 of the discharge unit 200 at the lower part and to smooth the discharge flow of the stored product in the silo.

As shown in FIG. 5, the inclined wall 230 may have a tilt angle of 70 degrees with the surface on which the discharge port 240 is formed.

Whether the inclined wall 230 is formed at a certain inclination angle is influenced by the particle diameter of the stored product stored in the silo and the adhesion force between the particles. In the case of limestone having high adhesion, the inclination angle needs to be larger.

In the case of the conventional silo, the inclination angle formed by the inclined wall 230 of the lower discharge port 240 and the discharge port 240 through which the stored product is discharged is generally about 60 degrees.

However, in the case of a deposit of a fine powder such as limestone having high adhesion, there is a problem in that the inclined wall 230 is insufficient in inclination angle to adhere to the inclined wall 230, resulting in a decrease in discharge flow of the stored matter in the silo.

Particularly, when the inclined wall 230 is provided so as to have an inclination angle of 70 degrees with the surface on which the discharge port 240 is formed, the inclined wall 230 is made of a fine powder material having high adhesion property including limestone, coal iron ore, The storage material can be smoothly discharged through the plurality of discharge units 200 formed at the lower end of the hopper 100 at an appropriate speed without being attached to the inclined wall 230. [

The slant wall 230 may be formed with a lining coating for preventing lateral attachment of the stored product.

This lining coating may be made of STS material and reduces the frictional force of the sloped wall 230 with the stock through the lining coating to prevent the deposit from adhering to the sloped wall 230. [ As an example, the lining coating may be provided to prevent the STS plate from being attached to the sloped wall 230 by being installed in the sloped wall 230. It is preferable that a member having a thickness of about 3 mm (3 t) is used as the thickness of the STS plate.

2 and 7, the cross barriers 220 may be formed in a manner such that the load of the dispersing unit 210 and the cross barriers 220 is lower than the load applied to the support walls 250 to the load transfer part 221.

As shown in the enlarged part of FIGS. 2 and 7, the load transmission part 221 is a part extending downward of the cross partition 220, and the load transmission part 221 is connected to the support wall 250 Can be installed. Specifically, the load transmission portion 221 is continuously disposed in the up-and-down direction with respect to the supporting wall 250 so that the load of the dispersion portion 210 and the crossing partition wall 220 supporting the dispersion portion 210 is directly transmitted to the sloping wall 230 And can be transmitted to the supporting wall body 250 below the inclined wall 230 in conjunction with the inclined wall 230. [

The load distribution structure of the dispersing portion 210 has a vertical load distribution structure that is not a side load distribution structure in which the load is transmitted to the inclined wall 230 to improve the load distribution of the inclined wall 230, The amount of the slant wall 230 can be reduced.

2, the cross barriers 220 are installed in a part of the height direction of the inclined wall 230, and the upper end of the cross barriers 220 is located at a height of the upper end of the dispersing part 210 May be the same or lower.

2, the cross barriers 220 are installed on a part of the inclined wall 230 that is not entirely in the height direction, thereby reducing the installation height of the cross barriers 220 in the dispersion part 210, It is possible to reduce the friction area of the cross partition 220, which is a deterioration factor of the discharge flow of water, and to smooth the discharge flow of the unloading of the deposit with high adhesion. In addition, the amount of work of the crossing partition 220 can be reduced by the portion of the crossed partition V that has been removed.

A Cardox device C may be installed on at least one of the inner wall of the hopper 100 and the inclined wall 230 to remove the stored material fixed by the expansion pressure of the gas.

In spite of the prevention of the adhesion of the deposit inside the silo and the facilitation of the discharge flow of the stored product in the silo through the optimization of the inclination angle of the inclined wall 230 and the reduction of the friction area of the crossing barriers 220 as described above, The Cardox apparatus C may be installed on the inner wall or the inclined wall 230 of the hopper 100.

The Cardox apparatus C is an apparatus for removing stored materials such as the inner wall of the hopper 100 and the inclined wall 230 inside the silo by an expansion pressure that instantaneously expands the liquid into a gas by electrical sparks or the like in the liquid material .

Typically, the Cardox apparatus (C) can easily remove the solidified material by the expansion pressure expanded by a gas such as carbon dioxide having a volume of 600 times or more by the electric spark or the like by the liquid material.
