Description

Detailed description of the invention

TECHNICAL FIELD The present invention relates to the transfer and filling of granular materials such as carbon black, and more particularly to a device necessary to move the granular materials filled in a flexible container to a transportation vehicle. It is.

Flexible containers made of cloth, synthetic fibers, etc. are generally used as containers for transferring powders such as carbon black. The flexible container transported out by a transportation vehicle or the like is temporarily installed in a predetermined place such as a building, and is temporarily placed there so that it can be transferred to a special vehicle or the like.
From such a temporary storage place, the flexible container is suspended by a crane such as a hoist, moved along a track, and released at the transshipment position with its bottom opened. The discharged granular material is transported to a predetermined position by a special lifting device, and then transferred to a predetermined transport vehicle.
JP 2018-131260 JP 2013-143972 In the prior art, fine particles discharged downward at the reloading work position scatter and have an adverse effect on contamination of the surrounding environment. I had a problem.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the problem of powder scattering caused by transfer from a flexible container, and to enable smooth transfer without contamination of the human body and the environment.

The present invention has been made in order to solve the above problems. , to prevent the particles from flowing out of the chamber to the outside, collect the empty flexible container, store it, and collectively collect it. Then, the granules flowing out from the flexible container are collected by the dust collector through the suction duct and recovered.
Further, as described above, the granules discharged into the chamber are transported to a predetermined position by the lifting device and transferred to the transport vehicle.

According to the present invention, in the transfer of flexible container powder, it is possible to transfer the flexible container powder without diffusing it around, and the advantage of being able to avoid contamination of the surrounding environment and adverse effects on the human body. There is

FIG. 3 is a side view of the main part showing the hoist installation of the flexible container transportation device according to the present invention together with the track.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail.
As shown in FIG. 1, a temporary ceiling hoist 2 is placed at a location where the flexible container 5 is placed in the building 1 and temporarily placed (four flexible containers are installed in the example) by a forklift or the like. Then, at the hanging position, the slinging hook work is performed by manual operation, and the movement of the flexible container 5 into the building is started. A plurality of hoists 2 are temporarily installed here. Tracks 12 (Fig. 7) and cables are provided so as not to interfere with mutual travel.

The suspended flexible container 5 (FIG. 1) is moved toward the building, and when it enters inside, the door 4 (FIG. 1) of the chamber 3 (FIG. 1), which is the work room, is opened, and the flexible container 5 is moved inside. The container is moved to the discharge position (FIG. 1), opened manually, and the powder (carbon black, etc.) is discharged downward.
After the discharge is completed, the empty containers are further advanced and moved to a receiving container 11 (FIG. 1) where they are sequentially collected, collected and pooled. After that, collection vehicles will be carried out periodically.

The unsealed and discharged granules are transported upward by a lifting device 6 (FIGS. 1 and 6) installed at that location.
This unsealing is performed in the chamber 3 (Fig. 1), and this chamber 3 (Fig. 1) is usually a decompression chamber. That is, a duct 7 (FIG. 1) is connected to the chamber 3 (FIG. 1), and this duct 7 (FIG. 1) is connected to an external dust collector 10 (FIG. 1) for suction. Granules collected by the dust collector 10 (FIG. 1) are collected in a collection bag and sent to the next process.

The lifting device 6 is configured as shown in FIG. 6 (indicated by an inclined conveying system), and a large number of disc-shaped discs 6A are connected to a cord-like body 6B at predetermined intervals. It is driven and rotated by pulleys positioned above and below to move in a loop. A gap is formed between the casing and the discs 6A, so that the particles are transferred in a free state, and the particles between the discs 6A are moved together with the air therebetween. Granules put into the lower inlet 6C are discharged from the upper outlet. The discharged granules are moved through the vibrating sieve 8 (Fig. 2) to the telescopic dust collecting and filling machine 9 (Fig. 2), from which they are discharged to the inlet of the carrier T (Fig. 2). It will be.

In short, the present invention connects an exhaust duct 7 (FIG. 1) to a chamber 3 (FIG. 4) in a building 1 (FIG. 4) and connects the duct 7 (FIG. 1) to an external dust collector 10 (FIG. 1). Then, the inside of the chamber 3 (FIG. 4) is configured to have a negative pressure, the flexible container 5 (FIG. 4) suspended on the hoist 2 (FIG. 4) is suspended and movable, and the chamber 3 (FIG. 4) Move to the work place inside, open the flexible container 5 (Fig. 4) at the place, drop and release the granular material, face the opening of the lifting device 6 (Fig. 2) at the work place, The granular material is conveyed upward and loaded on the carrier T (Fig. 2), and the released flexible container 5 (Fig. 4) is stored in the container 11 (Fig. 4) and collectively transported. It is what I did.

The dust collector 10 (Fig. 1) according to the present invention also has a suction capacity of 80 m3/min, and the negative pressure in the chamber 3 (Fig. 1) is maintained at approximately -3 KPa as the capacity of the blower. However, depending on the size of the building, a larger dust collector may be used. In short, the chamber is not a closed room, but allows air to flow in from the outside of the building, thereby sucking in the powdery material together with the outside air and collecting it in the dust collector 10 (FIG. 1).

INDUSTRIAL APPLICABILITY The present invention is used for powder processing related to powder transportation, and various aspects can be considered. In powder processing, it can be applied while avoiding adverse effects on the human body and the environment, and its application range is wide. .
