Description

  The present invention relates to an apparatus and a method for sucking a granular material such as an adsorbent and filling the container.

  In a container with an open top or a container with a lid, a hopper is used when the container is filled with a granular material such as an adsorbent. The hopper is installed in the upper part of the container, and the granular material is once accommodated in the hopper, then the gate is opened, and the granular material is filled by dropping. In this case, since the upper part of the container is filled, there is a problem that dust is generated and the working environment is deteriorated.

  In order to solve the above problem, a method and an apparatus have been proposed in which the upper part is closed and the inside of the container is decompressed, and then the gate of the hopper is opened to drop and fill the granular material (see Patent Document 1). In the above apparatus, a suction lid is disposed in close contact with the top of the holding frame placed on the surface plate, and a crimping plate having a plurality of suction holes and a plurality of filling nozzles is crimped to the top of the mold, and then communicated from the suction holes. A vacuum source is used to decompress the space formed by the mold closed by the suction lid and the pressure-bonding plate and the holding frame, and when the space is in a decompressed state, the particulate filler is suction-filled.

However, the above method and apparatus have a problem that a container having an opening only on the side surface cannot be filled. In multiple containers constructed by stacking multiple containers of the same shape, if each container is filled with an adsorbent and then stacked, the containers become heavy and difficult to stack, so it is necessary to fill them after stacking . In such a container, there is an opening only on the side surface, and it must be filled from the opening. Conventionally, a chute or the like is inserted through the opening and filled through the chute. In this case, the granular material container in which the granular material is stored must be installed at a higher position than the container to be filled. Also, the chute needs to be provided with a predetermined inclination, and it is necessary to construct an installation table and the like. In addition, when supplying through a nozzle provided in a container, since the nozzle is generally provided so as to protrude in the horizontal direction, particulate matter accumulates in the nozzle portion, and it is difficult to smoothly fill the container. In addition, there is a problem that it takes time for filling.

  FIG. 3 is a view showing a first embodiment of the filling apparatus of the present invention. In the embodiment shown in FIG. 3, it is shown that the filling device of the present invention is connected to the containers 20 and 30 shown in FIG. In FIG. 3, only the cross sections of the containers 20 and 30 overlapped in two upper and lower stages are shown, but as described above, a configuration in which three or more stages are overlapped may be used. Of the two openings formed by overlapping the upper and lower stages, the side into which the gas flows is defined as the first opening 40 and the side from which the gas is discharged is defined as the second opening 41.

  The filling device 50 according to the present invention does not open the upper part of the container like the containers 10 and 30 shown in FIGS. 1 and 2, and must supply the particulate matter through a limited opening such as the opening on the side of the container. It is a useful device for non-containable containers. The filling device 50 of the present invention includes a first closing member 53 that includes a first closing plate 51 that closes the first opening 40, a suction pipe 52 disposed on the first closing plate 51, and a second opening. A second closing member 57 that includes a second closing plate 54 that closes 41, a supply pipe 56 that is disposed on the second closing plate 54 and includes a suction nozzle 55 for sucking particulate matter, and a suction pipe 52. It includes a suction means 58 to be connected.

  The first closing plate 51 shown in FIG. 3 is formed with a hole continuous to the suction tube 52, and the first closing plate 51 provided with the suction tube 52 closes the first opening 40. The pair of 20 side plates 27a and 27b, the side plate 26a, and the side plate 32a of the lower container 30 are arranged in close contact with each other. The suction pipe 52 is connected to a line connected to the suction means 58 via a flange, for example.

  The second closing plate 54 shown in FIG. 3 has a continuous hole formed in the supply pipe 56, and the supply pipe 56 that communicates the inside and the outside of the container 30 through the hole is disposed. In this case, the gap can be sealed using a filling type sealing material such as a caulking material or an elastic sealing material so that the hole does not cause a gap between the second closing plate 54 and the supply pipe 56. Further, in the present invention, the supply pipe 56 can be provided by using a gasket, sandwiching the second closing plate 54 provided with a hole, and fastening with a flange. Similarly to the first closing plate 51, the second closing plate 54 is also arranged so as to be in close contact. That is, the second closing plate 54 is disposed so as to be in close contact with the pair of side plates 27 a and 27 b, the side plate 26 b, and the side plate 32 b of the lower container 30 of the upper container 20.

  By disposing the second closing plate 54, one of the supply pipes 56 is disposed inside the container 30 and the other is disposed outside the container 30. A suction nozzle 55 is provided at the other end, and the suction nozzle 55 is inserted into the adsorbent storage container 60 in which the particulate matter is stored. In this case, the suction nozzle 55 is surrounded by the granular material.

  As described above, the openings 40 and 41 are closed by the first closing plate 51 and the second closing plate 54, and the container 30 is closed. When suction is started by the suction means 58, the gas in the container 30 is sucked and the pressure in the container 30 is reduced. As the pressure in the container 30 is reduced, the particulate matter is sucked from the suction nozzle 55 and filled into the container 30 through the supply pipe 56.

  In the present invention, the suction means 58 can be a blower, a compressor, or a vacuum pump. The suction force can be increased as the pressure is closer to the vacuum. However, when the suction force is strong, the particulate matter is damaged by colliding with the supply pipe 56 or the container 30, and the predetermined performance is lost. For example, the inside of the container 30 can be depressurized by 1000 Pa. The pressure in the container 30 can be controlled by controlling the amount of suction gas by the suction means 58. Specifically, when the suction means 58 is a blower, it is performed by adjusting the guide vane, or by adjusting the discharge side valve, or by controlling the speed of the motor in case of inverter control.

In this case, the gasket is pressed between the side surface of the container and the closing plate along with the fastening by a fastening means such as a screw, and the airtightness inside the container when the gas is sucked can be maintained. The first closing plate 51 and the second closing plate 54 may be made of any material as long as it has a size capable of closing the first opening 40. For example, metals such as carbon steel and stainless steel, acrylic resin, polycarbonate resin, acrylonitrile-butadiene-styrene (ABS) resin, polyester resin, polyvinyl chloride (PVC), glass, glass fiber, and carbon fiber are used. be able to. In the present invention, since the pressure inside the container 30 is reduced and the pressure outside the container becomes higher, the mass of the first closing member 53 including the suction pipe 52 and the first closing plate 51, the supply pipe 56 and the second closing plate 54 are reduced. Depending on the mass of the second closing member 57 to be included, the first closing plate 51 and the second closing plate 54 can be pressed toward the side surface of the container without using the fastening means.

  As the suction pipe 52 and the supply pipe 56 shown in FIG. 3, those having a diameter suitable for sucking the gas in the container 30 and a diameter suitable for sucking the particulate matter can be used. The suction pipe 52 and the supply pipe 56 can be determined in consideration of the capacity of the suction means 58, the capacity of the container 30, the size and mass of the granular material, the filling amount of the granular material, and the like. The suction pipe 52 and the supply pipe 56 may be steel pipes such as carbon steel and stainless steel. For example, a plastic pipe such as polyvinyl chloride is preferable because it is inexpensive and lightweight. In the present invention, the plastic is preferable because the pressure is reduced to 1000 Pa. Moreover, the thickness of the 1st closing board 51 and the 2nd closing board 54 can be made into the thickness which can endure the said pressure reduction, for example, can be 0.01-0.03m.

The supply pipe 56 can be provided so that a hole having a predetermined diameter is provided at a predetermined position of the second closing plate 54 and penetrates the hole. In this case, the gap between the second closing plate 54 and the supply pipe 56 can be sealed with the sealing material described above. Further, the supply pipe 56 may be composed of two pipes having flanges disposed so as to sandwich the second closing plate 54 having a hole with a predetermined diameter at a predetermined position. In this case, the flange, the gasket, the second closing plate 54, the gasket, and the flange are arranged adjacent to each other in this order, and the supply pipe 56 and the second closing plate 54 are connected using fastening means such as screws. Can do.

  The supply pipe 56 is bent so that the tip inserted into the container 30 faces the bottom of the container 30, and a suction nozzle 55 is provided at the tip outside the container 30 serving as the other. The suction nozzle 55 is inserted into the adsorbent storage container 60 that stores the particulate matter, and can suck the particulate matter by the reduced pressure in the container 30.

  The chamber 63 shown in FIG. 4 can be a sealed container having a predetermined capacity. After the gas in the chamber 63 is first sucked and decompressed by the suction means 58, the gas in the container 30 is sucked into the container 63. The inside of 30 can be depressurized. The chamber 63 can be used to prevent surging from occurring in a blower or the like used as the suction unit 58 when gas is reduced in the container 30 due to rapid suction by the suction unit 58 or the like. Surging is a phenomenon in which the flow rate, pressure, and rotational speed fluctuate periodically when the flow rate is less than a predetermined amount, causing vibrations in the equipment. is there. In the present invention, it is possible to provide a chamber 63 having a capacity capable of always ensuring a gas flow rate of a predetermined amount or more sucked by the suction means 58.

  In the present invention, the chamber 63 can be a sealed container made of steel having a predetermined capacity. In addition, when using a blower or a compressor for the suction means 58, since the pressure is reduced to about 1000 Pa, a plastic sealed container can be used.
