【Example】
Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows an example of a container for a granular material according to the present invention. The container 1 for a granular material has a two-layer structure, and a container body 10 serving as an outer layer and a container body 10 serving as an inner layer. And an inner layer body 20 that accommodates the granular material.
[0010]
The container body 10 is made of a hard material such as a metal, and has a bottom portion 11 and a side wall portion 12 erected around the outer periphery of the bottom portion 11 and has an opening 13 on the upper side. are doing. Further, the cross-sectional shape is substantially semi-circular.
Through holes 14 and 15 are formed in the bottom portion 11 and the side wall portion 12 to allow external air to freely enter and exit between the container body 10 and the inner layer body 20. The bottom portion 11 is provided with one through hole 14 at the center thereof, and the side wall portion 12 is provided with a plurality of through holes 15 at predetermined intervals.
[0011]
The inner layer body 20 includes a flexible cloth body 21 and a weight 22 attached to the cloth body 21. The cloth body 21 is formed in a concave bag body whose upper side is opened, and the folded portion of the upper part 21a is provided on the upper part 12a of the side wall part 12 of the container body 10, as shown in FIG. 2, the cloth body 21 is fixed by a fixing member including a bolt 3 and a nut 4, and the cloth body 21 is housed and suspended in the housing recess 16 surrounded by the bottom 11 and the side wall 12 of the container body 10. It has a configuration.
[0012]
The weight 22 is formed in a disc shape with a heavy object such as a metal, and is attached to a position of the bottom 21 b of the cloth 21 corresponding to the bottom 11 of the container body 10 (the center of the cloth 21).
The granular material container 1 having the above-described configuration accommodates the measured granular material p such as sulfur or zinc in the cloth body 21 and is transported to a supply position where the powder p is charged into the mixer or the like from the top down. Then, from the state shown in FIG. 3A, the rotation is made 180 ° through the steps (b) and (c), and the state is completely reversed to the state shown in FIG.
[0013]
At this time, the cloth body 21 suspended inside the container body 10 rises with the rotation of the granular material container 1 and jumps out of the container body 10 while being tensioned by the weight 22, The moving action is performed so as to completely protrude below the main body 10. The cloth body 21 protruding downward is in a state where tension is applied to the entire cloth body by the weight 22 attached thereto. For this reason, the stored granular material p is reliably removed without adhering to the cloth 21.
[0014]
Further, since the through holes 14 and 15 are formed in the container body 10, external air can freely enter the space between the cloth body 21 and the container body 10. Therefore, with the inversion of the container 1, the movement of the cloth body 21 that moves so as to be protruded while being pulled by the weight 22 can be easily moved, and the granular material p can be further removed from the cloth body 21.
[0015]
After the powder p is charged, the container 1 is returned to the state shown in FIG. 3A again. However, since the weight 22 is provided at the position of the bottom 21b of the cloth 21, the cloth 21 is It is possible to surely return to the original state accommodated inside the inside 10. Moreover, since the air in the space between the cloth body 21 and the container body 10 can be released to the outside through the through holes 14 and 15, the cloth body 21 is formed along the shape of the container body 10 as shown in FIG. Can be quickly returned to the state.
[0016]
As described above, in the present invention, the container for powder and granular material that discharges the powder and granular material p that is accommodated by inversion is formed by the inner layer body 20 suspended inside the container body 10 and the cloth body 21 having flexibility. And the weight 22 attached thereto, so that when the container 1 is turned over, the cloth 21 accommodating the granular material p performs a moving action so as to protrude downward so as to fall, and Since the whole cloth body 21 is pulled while applying tension by 22, the powder p is not adhered to the inside of the container as in the related art, even if the powder has strong adhesion. For this reason, it is not necessary to periodically clean the inside of the container.
[0017]
Further, even if the granular material has a strong adhesive property, the granular material p can be prevented from adhering to the cloth body 21 and can be further prevented from adhering to the container as compared with the related art. Supply accuracy can be improved and the surrounding environment is not adversely affected.
The material of the cloth body 21 is not particularly limited as long as it does not break easily and has durability equal to or higher than a predetermined level. Preferably, the powder p hardly adheres. For example, a Teflon filter cloth can be used.
[0018]
In addition, the weaving method of the cloth used for the cloth body 21 may be a conventionally known weaving method as long as the granular material p does not leak down when the cloth is stored. For example, a twill weave or the like is preferably used. Can be. In addition, a non-woven fabric can be similarly used as the cloth body 21.
The coarseness of the cloth body 21 is not particularly limited as long as the accommodated powders p do not leak downward.
[0019]

Is provided at least on the side wall portion 12, whereby the cloth body 21 can be quickly returned to the state shown in FIG. 3A along the inner shape of the container body 10.
[0020]
Instead of the through holes 14 and 15, a device for forcibly supplying and discharging air to and from the space between the cloth body 21 and the container body 10 may be connected. However, the structure of the above embodiment in which a through hole is provided in the container body 10 is preferable because the structure is simple and the cost is low.
Note that the above-mentioned powdery particles p indicate a state of only powder, a state of only particles, and a state of mixing powder and particles.
[0021]
Hereinafter, the present invention will be described more specifically.
The cloth was made of Teflon filter cloth with a twill weave, and the grain size was 211 lines / 2.54 cm, 95.5 lines / 2.54 cm in width, and 1 kg was placed at the bottom of the cloth. A weight was attached, and a container of the present invention having a configuration as shown in FIG. 1 was manufactured. In addition, a conventional container 1 made of stainless steel and a conventional container 2 having an inner surface subjected to a surface treatment were obtained.
[0022]
Each of these test containers was attached to an inverting device, and as a powder, using zinc oxide and sulfur, which have strong adhesion, under the measurement conditions shown below, an evaluation test of the powder adhesion was performed. The result shown in FIG.
Adhesiveness Using each test container, repeating the operation of putting the weighed powders and granules into the mixer for 24 hours, measuring the amount of powders and powders adhered to each test container, and determining the result. The evaluation was performed using an index value with the conventional container 1 being 100. The smaller this value is, the smaller the adhesion of the powder is, which means that the adhesion is prevented.
