Description

[Detailed Description of the Invention] This invention relates to an improvement of a silo for mixing and storing two or more types of granular materials having different masses, such as rice, wheat, etc., that is, a structure for uniformly discharging the silo.

A conventional example of this type of silo is one shown in FIG. 1, for example.

This silo 1 can freely supply and store two or more types of mixed powder and granular materials 5 of different masses, such as rice, wheat, etc., into the interior 4 from an input port 3 formed in an upper part 2, and has a tapered bottom part 6.
The mixed powder and granular material 5 is taken out from a take-out lower provided at the tip.

However, in such a conventional silo 1,
When taking out the mixed powder and granular material 5, the tapered bottom part 6 provides a flow resistance to the mixed powder and granular material 5 at the lower outer part of the silo 1, and it is easy to form a bridge 8 near the bottom part 6 of the silo 1. Since the flow rate at the center is higher than the flow rate at the periphery, the powder 5 with a large coagulation mass, such as rice, gathers in the center, and other powders 5 with a small mass, such as wheat, gather at the center. , gather on the outside and separate, and the powder or granular material 5 with a larger mass is taken out first, and then the powder or granular material 5 with a smaller mass is taken out.

Therefore, for example, if powder and granules of large mass and small mass are filled in the silo 1 at a mixing ratio of 8:2, this mixed powder and granular material 5 is
There was a problem in that it was difficult to take out the mixture at a uniform mixing ratio of 2:2.

This idea was made by focusing on the above-mentioned problems of the conventional method, and it solved the above-mentioned problems of the conventional method by providing a means for uniformly flowing powder and granular materials inside the silo, which is equipped with a large number of cylindrical vertical flow channels. It is intended to.

Specifically, the uniform take-out structure of a silo according to this invention is such that the silo has a circular cross section in the uniform take-out structure of a silo that mixes and stores two or more types of powder and granules having different masses. , a plurality of cylindrical bodies facing from the outside toward the center and having smaller diameters are erected and combined inside the silo to form a cylindrical uniform flow means, and the entire upper surface of this equal flow means is curved in a convex shape from the outside toward the center; The gist is that the entire lower surface has a corresponding tapered shape, leaving a gap with respect to the bottom of the silo.

This invention will be explained below based on the drawings.

Incidentally, in the following, parts similar to those in the prior art are designated by the same reference numerals and redundant explanation will be omitted.

FIGS. 2 and 3 are diagrams showing an embodiment of this invention.

In the figure, reference numeral 10 denotes a uniform flow means, which is disposed inside the silo 1 having a circular cross section, leaving some space above.

This uniform flow means 10 includes a plurality of cylindrical bodies 11. Specifically, the cylindrical pipes 16 are combined to form a large number of cylindrical vertical flow paths 12, and the entire upper surface 13 is curved from the outside toward the center to form a convex shape so that the mixed granules 5 can flow through each vertical channel. It can be evenly distributed in the flow path 12.

Then, from the outer circumference to the center, the base cylindrical pipe 16 is
By reducing the diameter of the particle, the mixed powder and granular material 5 can be uniformly dispersed.

Further, the entire lower surface 14 is formed into a tapered shape corresponding to the bottom 6 of the silo 1 to prevent the bridge 8 from being formed near the bottom 6.

Furthermore, by providing an umbrella-shaped resistor 40 on the bottom 6 side of the silo 1, the load of the powder and granular material applied to the bottom 6 of the silo 1 is dispersed, and bridging prevention and uniform takeout are further improved. .

Further, the resistor 40 is vertically adjustable via an adjustment device 41.

The materials for forming this uniform flow flat means 10 are as follows:
The material is not limited to the above-mentioned cylindrical pipe 16, but any material such as wire mesh that can define the cylindrical vertical flow path 12 may be used.

Further, a gap 15 is formed between the lower surface 14 of the uniform flow down means 10 and the bottom part 6 of the silo 1, which allows the mixed powder and granular material 5 to freely flow down to the extraction lower side.

Furthermore, the lower surface 14 of the uniform flow means 10 and the bottom 6 of the silo 1
The gap 15 between the two is set to be large at the upper position and small at the lower position.

Next, the effect will be explained.

First, two or more types of mixed powder and granular materials 5 having different masses are charged into the interior 4 of the silo 1 at a mixing ratio of 8:2, for example, through the input port 3 of the upper part 2. The mixture falls onto the upper surface 13 and is evenly distributed through the curved shape of the upper surface 13 into each of the cylindrical vertical channels 12 at the same input mixing ratio and stored therein.

When the mixed powder and granular material 5 is taken out, the mixed powder and granular material 5 with an even mixing ratio housed in each of the cylindrical vertical flow channels 12 flows vertically down with almost no resistance, and the lower surface of the uniform flow down means 10. 14, through the gap 15, and is taken out from the take-out lower with an even mixing ratio of 8:2.

Further, in this case, the load of the granular material applied to the bottom part 6 is dispersed by the umbrella-shaped resistor 40, so that no bridge 8 is formed near the bottom part 6, and smooth and even removal can be achieved.

As explained above, according to this invention, in the structure of the silo for mixing and storing two or more types of powder and granules having different masses, the silo has a circular cross section. , A plurality of cylindrical bodies facing from the outside toward the center and having smaller diameters are erected and combined inside the silo to form a cylindrical uniform flow means, and the entire upper surface of this equal flow means is formed into a convex curved shape from the outside toward the center. Since the entire lower surface is tapered to leave a gap in relation to the bottom of the silo, the mixed powder and granules fed into the silo are fed into a number of vertical channels on the upper surface of the uniform flow means at an even mixing ratio. The mixed powder and granular material can be stored as is, and the mixed powder and granular material can be flowed down without resistance when taken out, so it is possible to take out the mixed powder and granular material with an even mixing ratio, and it also prevents the occurrence of bridging near the bottom of the silo. This has the effect of allowing smooth removal.
