Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container for transporting powder and granular materials.

Conventionally, bags made of flexible sheet materials, containers made of steel plates, etc., and equipped with an appropriate transport mechanism inside have been used as means of transporting powder and granular materials, but in the case of bags, Various improvements have been made to smoothly discharge the contents, resulting in a complicated structure and cumbersome handling.Containers with an ejection mechanism are expensive to manufacture and therefore have drawbacks such as high transportation costs.

5 From this point of view, conventionally, a cloth bag formed in a substantially rectangular parallelepiped shape is provided with a filling chute, a take-out chute, an air venting device, etc., and is supported on a frame wall such as a loading platform on the side wall of the bag. A supporting metal fitting is attached, and a wire mesh serving as a base is covered with a breathable cloth on the inside bottom of the bag to form an air chamber, and air is configured to be pressurized into this air chamber from the outside. Powder container devices that can be loaded in a tiltable loading platform have been proposed.

However, in this type of container device, 15
Since the overall shape of the bag is a rectangular parallelepiped, simply providing an air chamber in the bottom does not allow for smooth discharge of powder and granular material, nor is it possible to efficiently fill the powder. There is a point. Therefore, as a result of various studies and trial production20, the inventors decided to incline the lower half of the bag inward over its entire circumference, and to prevent the powder from flowing out onto one side of the tilted bag. A channel is extended to form an outflow port, an inflow channel is extended above the inflow channel to form an inflow port, an air slide is provided at 25 to be freely inserted and removed from the opening of the outflow channel, and the upper half of the bag body is A hanging device is disposed on the outer surface of the bag, and the bag is suspended and fixed via the hanging device in a container having an open side, and the slanted side surface of the bag is attached to an inclined support member within the container. By configuring the bag to be supported by the container, filling, discharging, and discharging of powder and granules can be accomplished quickly and smoothly, and the air slide can be maintained and the inside of the bag can be cleaned while the bag remains attached to the container. It has been found that this can be easily achieved and a shipping container with good workability can be obtained.

35 Therefore, it is an object of the present invention to have a simple structure, to be manufactured at a low cost, to be immediately applicable to existing containers, to achieve filling and discharging of contents efficiently, easily and quickly, and further to It is an object of the present invention to provide an easy-to-handle container for transporting powder, granular materials, etc., which allows cleaning or maintenance of the inside of the bag body when the container is attached to the container.

In order to achieve the above object, the present invention uses a flexible sheet material to form a rectangular parallelepiped bag, and the lower half of the bag is inclined inward over its entire circumference. At the same time, an outflow path for the powder and granular material is provided on one side of the inclined bag, and an inflow path for the powder and granular material is provided above the same side surface of the bag on which this outflow path is provided. An air slide is provided so that it can be inserted and removed from the opening of the body outflow passage, and a hanging device is placed on the outer surface of the upper half of the bag, and the bag configured in this way is placed in a container with one side open. Each is suspended and fixed via a hanging device,
Furthermore, the bag is characterized in that the inclined side surface thereof is supported by an inclined support member disposed at the bottom of the container.

Other objects and advantages of the present invention will become more apparent from the following description.

Next, preferred embodiments of the container for transporting powder and granular materials according to the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, the shipping container according to the present invention has a rectangular parallelepiped shape and is made of waterproof and tough flexible sheet material such as vinyl chloride tarpaulin, synthetic rubber, polypropylene cloth, or waterproof canvas. It basically consists of a bag 10 formed into a shape, and a regular-shaped container 12, such as a Japanese National Railways cargo container, in which the bag 10 is housed.

An appropriate number of fixing devices 14 are fixed to the top and sides of the outer surface of the bag body 10 by means such as welding or sewing.
A hanging device 16 is attached to the bag body 10, and an inlet port 18 for powder, granular material, etc. is formed on the upper side of the bag body 10, and a cylindrical inflow port 18 made of the same flexible material as the bag body is formed in the inlet port 18. Road 20
Connect and place. Further, the bag body 10 has a lower side surface inclined inward to form a bottom portion narrower than the upper portion, and an air slide 22 is disposed within the bottom portion so as to be freely inserted and removed from an outlet to be described later.

In addition, an outlet 24 for powder, granules, etc. is formed in the lower part of the bag 10 at a position corresponding to one end of the air slide 22, and this outlet 24 is also made of a bellows-shaped flexible material similar to that of the bag body. A rectangular cylindrical outflow passage 26 formed in the above is connected. In this case, it is preferable to attach a tightening belt 28 to a part of the outflow path 26 and tighten the belt 28 with a stopper 30 arranged on the side of the bag body to close the outflow path 26 (
(See Figure 2). The bag 10 configured in this way is stored in the container 12, and the hanging device for the bag 10 is attached to the container 12.
The bag is hung by hooks 32 placed at predetermined locations, and the bottom of the bag is supported by an inclined support member 34 made of steel that is removably attached to the bottom of the container 12.

On the other hand, the sliding surface 36 of the air slide 22 is made of a porous material having uniform air permeability, such as canvas cloth, aspest, ceramic, or synthetic fiber cloth.
The air supply pipe 3 is configured to be inclined at an angle of 4 to 8 degrees with respect to the outlet 24 from an external air supply device (not shown).
The powder and granules on the slide surface 36 are fluidized over the entire surface of the slide by low-pressure air pumped through the outlet 2.
4 to the outflow path 26.

Next, the functions and effects of the shipping container according to the present invention configured as described above will be explained. First, when filling powder or granules, etc., an air slide 22 is placed at the bottom of the bag 10.
is placed, and with the air supply pipe 38 led out from the outflow path 26, the outflow path 26 is folded and the outflow port 24 is closed by the belt 28 and the stopper 30. Next, the inflow path 20
After filling the bag body 10 with the powder through the inlet 18, the inflow path 20 is closed by an appropriate means, the door 40 of the container 12 is closed, and the bag body 10 is transported to a destination.

When discharging the powder, after opening the door 40 and removing the belt 28 from the stopper 30 to open the outflow path 26, the air supply pipe 38 of the air slide 22 is connected to an external air supply device (not shown).
The granular material is fluidized over the entire surface of the slide surface by low-pressure air uniformly jetted from the slide surface 36, and is discharged to the outside through the outlet 24 and the outlet path 26.

As is clear from the embodiments described above, the transportation container according to the present invention prevents the granular material from being bridged inside the bag by inclining the lower half of the bag inward over its entire circumference. This phenomenon can be easily avoided, and by providing the powder inlet and outlet on the same side, the powder can be taken in and out while the bag remains fixed at all times. By making the bag removable, the interior of the bag can be easily cleaned, the bag can be easily maintained, and many other advantages can be obtained.

In particular, the container of the present invention can be immediately installed in an existing container, and the bag can be handled as described above while attached to the container, so it has the advantage of significantly reducing transportation costs. has. The preferred embodiments of the container for transporting powder and granular materials according to the present invention have been described above, but it goes without saying that various design changes can be made without departing from the spirit of the present invention.
