Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for stacking bulk materials into silos.

As a conventional device for stacking bulk materials into a silo, the following device is a known example close to the present invention.

That is, a plurality of through-holes for charging were provided at appropriate intervals in a plate-shaped charging member that was suspended from the top of the silo so that it could be raised and lowered inside the silo, and that was airtightly inscribed in the inner wall surface. Bulk materials are supplied to the input through-hole via a conduit that communicates the bulk material loading hopper and the input through-hole, and the bulk materials are always placed close to the loading surface from near the bottom to the top. There is a way. In this case, the stowage upper part forms a plurality of conical shapes due to the relationship between the position of the input through-hole and the angle of repose of the bulk material.

According to this conventional method, when one through hole for loading is provided in the center and four holes are equally spaced on the same circumference, the condition of the upper part with bulk materials is determined by each through hole for loading. It forms five cones with vertices pointing vertically downward. In such a loading state, a valley is formed between the conical shapes and the loading efficiency is reduced.

Increasing the number of charging through holes on the same circumference complicates the structure of the charging section, and since the power unit is installed in the loading section inside the silo, it is extremely difficult to handle bulk materials that may cause a dust explosion. involves danger.

An object of the present invention is to improve loading efficiency without using a power unit.

The main points of the present invention are as follows: As a basic configuration, a chute in the shape of a square is attached to the bulk part of the silo so as to be horizontally rotatable, and blades angled with respect to the vertical plane are arranged in the bulk material passage space. It has a structure in which a blade is provided integrally with the chute, and a part of the bulk material fed into the silo is discharged vertically downward from the gap between the chute entrances, and the other part hits the blade and then is released into each silo. The bulk material is dispersed and discharged in a V-shape through the chute, and furthermore, due to the reaction force of the two noses, each sheet turns horizontally, and the discharge trajectory from the chute becomes annular.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

As shown in FIG. 1, a charging hopper 2 is installed in the upper center of a silo 1 for receiving bulk materials 9 so as to communicate between the inside and outside of the silo 1. The lower end of this hopper 2 is flanged, and an annular rail 4 is mounted on this flange. A roller 3 is mounted on the rail 4, and this roller 2
-3 is rotatably attached to chute A.

The chute person has a conical upper skirt plate 7 whose upper part is cylindrical and whose cross section is shaped like the letter "C" from the middle downwards, a lower skirt plate 8 arranged in the shape of the letter "C" in cross section within the upper skirt plate 7, and each of the upper and lower skirt plates. 7.8, and the cross section of the chute passage is V-shaped.

A blade 6 is attached to the cylindrical portion of shoe A, and this blade 6 protrudes to a position where it hits the bulk material 9 thrown in from the hopper 2. As shown in Fig. 2, the blade 6 is set at an angle θ with respect to the vertical plane, so that when the loose object 9 hits the blade 6, a horizontal component force B is generated on the blade 6 as a reaction force. It is.

In this embodiment with such a configuration, a portion of the loose material 9 that has fallen from the hopper 2 is discharged downward at a distance l from the upper part of the lower skirt 8 in a V-shaped configuration. After hitting the vane 6, the other loose material 9 enters the chute passageway between the upper and lower skirts 7,8. When the loose object 9 hits the blade 6, the chute A is horizontally rotated by the roller 3 due to the horizontal force B. Shoe) When A rotates horizontally, the loose object 9
Pass through the chute passage between the upper and lower skirts 7 and 8.
“□ (□) is not only dispersed in a V-shape, but also released in an annular state due to the swirling action.Furthermore, due to the centrifugal force of the rotation, the loose materials 9 are widely dispersed, forming a conical shape at the center and an annular shape at the outer periphery. This eliminates the problem of conical stacking around the outer periphery, and the dispersion effect improves stacking efficiency.

In addition, since the impact force of the loose object 9 on the blade 6 is converted into the turning force of the shoe A, a power device such as an electric motor for turning is not required, and there is no possibility of a dust explosion, making it safer.

As described above, according to the present invention, the stowage inside the silo is conical only in the central part, and continuous in a ring shape in other parts, so the stowage efficiency is good and the silo is also circular. The advantage is that a power device is not required for dispersion.
