[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transporting a powdery transported material such as cement into a transporting passage by a transporting means, and transporting the transported material by a transporting gas which is pressure-fed to the transporting passage. The present invention relates to a transportation device to be used.

[0002]

2. Description of the Related Art Conventionally, for example, in the case of transporting a powdery transported material such as cement to a concrete manufacturing plant or the like, the transported material is mixed with a transport gas such as air which is being pumped in a transport passage. Transport devices for transport are widely used. Further, in this type of transport apparatus, a rotary feeder is used as transported article supply means for supplying the transported article to a transport path. The rotary feeder is provided with a rotating body in which a plurality of partitioning chambers are formed in a casing in a rotating direction. Therefore, the transported goods stored in a hopper or the like are sequentially put into the respective partitioning chambers, and the rotary feeder sequentially transfers the transported goods stored in the respective partitioning chambers to the transport passage based on the rotation of the rotating body. Supply.

However, the conventional rotary feeder is
The high-pressure transport gas was flowing into the empty partition chamber after supplying the transported articles while the transported articles stored in the partition chambers were supplied into the transport passages by the rotation of the rotating body (hereinafter, referred to as “transported articles”). The inflowing transport gas is referred to as “inflow gas”.)
Therefore, a resistance pressure similar to the transport resistance in the transport device is applied to the inside of the casing, and the inflow gas is blown up in the casing by the rotation of the rotating body. As a result, the cargo to be supplied into the empty compartment is blown up by the inflow gas, and it has been difficult to accommodate a predetermined amount of the cargo in the empty compartment. Therefore, the conventional rotary feeder is provided with a unit for sucking the inflow gas flowing into the empty partition chamber by the suction unit and bringing the empty partition chamber into a negative pressure state.

As such means, for example, a configuration disclosed in Japanese Patent Application Laid-Open No. H6-110073 (hereinafter, referred to as “conventional configuration”) has been proposed. That is, in the conventional configuration, an air vent hole is formed in the casing so as to communicate with the empty partition chamber, and the air vent hole is connected to an air vent tube provided with a strainer in the middle thereof. Further, a suction pump is connected to an end of the air vent pipe, and by driving the suction pump, gas flowing into the empty partition chamber is sucked through the air vent pipe. As a result, the empty partition chamber is in a negative pressure state, and a predetermined amount of transported goods can be stored.
In addition, since the transported matter remaining in the empty compartment is mixed with the sucked inflow gas, in the conventional configuration, the inflow gas sucked by the suction pump is filtered by the strainer.

[0005]

However, in the conventional configuration, although the inflow gas after filtration is discharged from the suction pump, generation of dust can be suppressed.
The transported material accumulates on the strainer, causing clogging of the filter. Therefore, the replacement work (cleaning work) of the filter is complicated, and the transported material deposited on the filter is discarded, thereby wasting resources.

SUMMARY OF THE INVENTION The present invention has been made in view of the problems existing in the prior art, and has as its object to treat the inflow gas sucked by the suction means in a state where it can be effectively reused.

The inflow air is sucked from a portion different from the suction portion for sucking the inflow air from the suction port. The second sub suction passage 32 is a suction passage for sucking dust generated when a transported object is put into the hopper 16, and the dust is taken together with the inflow air sucked from the air vent hole 30. It is designed to be sucked. Further, the outside air suction passage 33 is a suction passage for taking in outside air, and the outside air is sucked together with the inflow air sucked from the air vent hole 30.

Next, the suction fan 18 will be described.
The rotary feeder 15 is disposed adjacent to the rotary feeder 15 via a connecting tube 34 joined to the rotary feeder 2a. The suction fan 18 is provided with a casing body 35 having a horizontal cylindrical shape.
A rotary shaft 36 connected to a driving device M (such as a motor) is rotatably supported at substantially the center of the casing body 35. Also, on the outer peripheral surface of the rotating shaft 36,
A plurality of blades 37 arranged in the casing body 35 are attached at a predetermined equal pitch in the circumferential direction.

Further, the suction fan 18 takes in the inflow air (including dust and outside air) so as to be located substantially at the center of the casing body 35 and on the same axis as the rotation shaft 36. The suction tube 38 is connected to the connection tube 3
4 are arranged so as to pass through. The suction passage 19 communicating from the air vent hole 30 to the suction fan 18 includes the air vent hole 30, the hollow portion S1 of the housing 22,
It is formed by a connecting cylinder 34 and a suction cylinder 38. A discharge hole 39 for discharging the inflow air sucked through the suction tube 38 is provided on one side surface of the casing body 35, and the inflow air is supplied to the dust collector 20 through the discharge hole 39. A discharge path 21 for discharging is connected.

Accordingly, the suction fan 18 receives the rotation power from the driving device M, rotates the rotation shaft 36 in a predetermined direction at a predetermined rotation speed, and sucks the inflow air through the suction passage 19. It has become. Then, the inflow air is supplied to the discharge holes 3 by the respective blades 37.
9 and is discharged to the discharge path 21 from the discharge hole 39. Further, the inflow air discharged into the discharge path 21 is taken in by the dust collector 20 and subjected to a predetermined process by the dust collector 20.

Next, a description will be given of the dust collector 20. A pulse type dust collector 20 is connected to the discharge path 21, and the inflow air sucked by the suction fan 18 through the discharge path 21 is connected to the dust collector 20. Is taken in. Then, the dust collector 20 separates and collects the transported material from the inflow air, and transports the transported material in a predetermined direction (vertical direction in the present embodiment) by jetting air.
To be paid off. Further, the inflow air from which the transported material has been removed is discharged into the outside air through a discharge pipe 40 provided in the dust collector 20.

Further, a supply pipe 41 is provided in the dust collector 20, and the supply pipe 41 is arranged corresponding to the side of the hopper 16 which receives the transported goods. Therefore, the transported material that has been separated and collected by the dust collector 20 and then removed is supplied again into the hopper 16 through the supply pipe 41. Then, the transported object is again stored in the partition room R transferred to the supply position by the rotation of the rotating body 26 of the rotary feeder 15. That is, in the present embodiment, the transported material is separated from the inflow air, and the transported material is transported again by the transport device 10, so that the inflow air can be reused.

Next, the transport device 10 constructed as described above is used.
The mode of transporting the transported goods using is described. The rotating body 26 rotates in the counterclockwise direction shown in FIG. 2 by the rotational power of the driving device in a state where the transported goods are stored in the hopper 16. Then, the transported object in the hopper 16 is charged by a predetermined amount into the partition R reaching the supply position, and is transported toward the discharge position in a state where the transported item is stored. In addition,
The suction fan 18 and the dust collector 20 are operating at the same time as the operation of the transport device 10 is started.

When the partitioning chamber R reaches the discharge position, the compressed air that has passed through the upstream transport pipe 12 is pumped into the partitioning chamber R, and the transported material is forcibly forced by the compressed air. It is transported to the downstream transport pipe 13 side. Thereafter, the transported material is transported toward the processing device 17 while being mixed with the compressed air. Further, the transported material is transferred to the transport passage 11 (downstream transport pipe 1
The partition room R after being supplied to 3) becomes an empty partition room R, and is transferred toward the supply position on the downstream side in the rotation direction of the rotating body 26. At this time, the inflow air is flowing into the empty partition R through the upstream transport pipe 12.

When the empty space R is transferred to the position corresponding to the air vent hole 30 in this state, the inflow air in the empty space R is passed through the suction passage 19 by the suction fan 18. It is forcibly sucked. Further, the transported matter remaining in the empty partition R is sucked together with the inflow air. As a result, the inside of the empty room R is in a negative pressure state, and when the empty room R reaches the supply position, the goods are stored so as to be sucked into the empty room R, and a predetermined amount of the goods Can be supplied. Further, the suction fan 18 transfers the inflow air through the first sub suction passage 31 and the hopper 1 through the second sub suction passage 32 together with the inflow air in the empty partition chamber R.
The outside air is sucked through the outside air suction passage 33 from the dust generated in the inside 6.

Then, the inflow air (including dust and outside air) sucked by the suction fan 18 is discharged to the discharge path 21 through the discharge hole 39 of the suction fan 18, and then is discharged to the dust collector 20. It is captured. In the dust collector 20, the transported material is separated and collected from the inflowing air, and the air from which the transported material is removed is discharged to the outside through the discharge pipe 40. On the other hand, the transported material separated from the inflow air is sequentially supplied into the hopper 16 through the supply pipe 41.

That is, the transported material contained in the inflow air is transferred to a passage different from the transport passage 11 (suction passage 19 (suction fan 18) → discharge passage 21 → dust collector 20 → hopper 1).
6), and sequentially transported to the most upstream side in the rotation direction of the rotary body 26 of the rotary feeder 15. Then, the transported material is again stored in the partition chamber that has reached the supply position, and then is transported to the discharge position by the rotation of the rotating body 26 (the rotary feeder 15) and is supplied to the transport passage 11. .

Therefore, according to the first embodiment, the following effects can be obtained. (1) The inflow air sucked by the suction fan 18 is:
The dust is collected by the dust collector 20. And
In the dust collector 20, the transported material is separated and collected from the inflow air, and the transported material is supplied (input) to the hopper 16. Therefore, the transported goods can be stored again in the partition R of the rotary feeder 15 and supplied to the transport passage 11. Therefore, the inflow air can be treated in a state where it can be effectively reused.

(2) Since the transported goods are returned into the hopper 16, a predetermined amount of transported goods required by the processing device 17 can be transported. Therefore, it is possible to contribute to improving the transportation efficiency of the transportation device 10.
Further, it is possible to contribute to effective use of resources without having to dispose of the transported material.

(3) Further, the transported goods are sequentially returned into the hopper 16 while the transporting apparatus 10 is operating. Therefore, there is no need to stop the operation of the transport device 10 when collecting the transported items, and it is possible to contribute to improving the transport efficiency of the transport device 10. In particular, when transporting different types of transported goods by the same transporting apparatus 10, the transported goods can be transported continuously without having to stop the transporting apparatus 10 each time.

(4) The inflow air is forcibly sucked by the suction fan 18. for that reason,
For example, the inflow air can be more reliably sucked than in a case where the inflow air is recirculated by a bypass pipe that connects the air vent hole 30 and the hopper 16. Therefore, it is possible to more reliably suppress the transported goods from being blown up.

(5) The suction fan 18 is connected to the first sub suction passage 31 which is provided at a different position from the suction passage 19.
The inflow air is sucked through. Therefore, the leakage of the inflow air can also be sucked, and the blow-up of the transported object can be suppressed more reliably. In particular, by sucking the inflow air from the vicinity of the intake port 23b where the inflow air blows up due to the resistance pressure applied to the inside of the casing, it is possible to more reliably suppress the blowup of the transported goods.

(6) The suction fan 18 sucks outside air through the outside air suction passage 33 together with the inflowing air. Therefore, the suction effect of the suction fan 18 can be more effectively operated, and the suction effect of the inflow air can be enhanced.

(7) The suction fan 18 sucks dust generated in the hopper 16 through the second sub suction path 32. Therefore, the hopper 16
It is possible to suppress dust generated when a transported object is put into the inside. In particular, when the upper part of the hopper 16 is open, it is possible to contribute to the improvement of the working environment without scattering dust to the outside. Further, since the transported substance in the dust is returned to the hopper 16 again through the suction path 19, the transported substance can be supplied to the transport path 11 without waste.

(Second Embodiment) Hereinafter, a second embodiment of a transport device according to the present invention will be described with reference to FIGS. In the following description, the same components as those of the above-described embodiment will be denoted by the same reference numerals, and redundant description will be omitted.

In the transport device 10 of the present embodiment, the first
Instead of the dust collector 20 and the discharge path 21 in the embodiment, an ejector 4 as a joining means indicated by a two-dot chain line in FIG.
2 and a discharge path 43. The ejector 42 is provided in the middle of the downstream transport pipe 13 as shown in FIG. 4, and the transported material is supplied to and mixed with the ejector 42 by the rotary feeder 15. The compressed air passes therethrough.

A discharge passage 43 for discharging the inflow air to the ejector 42 is connected to the discharge hole 39 of the suction fan 18, and the discharge passage 43 extends toward the ejector 42. Have been. Then, the inflow air sucked by the suction fan 18 is discharged to the ejector 42 through the discharge passage 43 and is sucked into the downstream transport pipe 13 by the suction action of the ejector 42. . That is, in the present embodiment, the inflow air is merged into the transport passage 11 of the transport device 10 so that the inflow gas is processed in a reusable state.

Next, the transport device 10 constructed as described above will be described.
The mode of transporting the transported goods using is described. The manner in which the inflow air is sucked by the suction fan 18 is the same as in the first embodiment, and a description thereof will be omitted.

The inflow air is sucked through the suction passage 19 by the suction fan 18 and then discharged toward the ejector 42 through the discharge passage 43.
The compressed air in which the transported material is mixed passes through the transport passage 11 (downstream transport pipe 13), and the compressed air passes through the ejector 42. At this time, in the ejector 42, a suction force enough to take in another fluid (in the present embodiment, the inflow air) acts on the ejector 42 due to the passage of the high-pressure pumping air. .

Therefore, the inflow air discharged to the discharge passage 43 is sequentially sucked into the downstream transport pipe 13 by the suction force of the ejector 42. The compressed air passing through the transport passage 11 and the suction passage 1
The inflow air that has passed through 9 merges in the downstream transport pipe 13. That is, the transported material contained in the inflow air is supplied to a passage (suction passage 19) different from the transport passage 11.
(The suction fan 18) → the discharge path 43 → the ejector 42), and then the transport path 11 (the downstream transport pipe 1) again.
3). As a result, the transported substances contained in the compressed air and the inflow air are merged via the ejector 42 and then transported to the processing device 17 side.

Therefore, according to the second embodiment, the following effects can be obtained in addition to the effects (4) to (7) of the first embodiment. (8) The inflow air sucked by the suction fan 18 is discharged to the downstream transport pipe 13 via the ejector 42. Therefore, the transported goods contained in the inflow air can be combined with the transported goods being transported in the transport passage 11. Therefore, the inflow air can be treated in a state where it can be effectively reused.

(9) Further, the inflow air is directly discharged to the downstream transport pipe 13 by the ejector 42. Therefore, a device for separating the transported goods from the inflow air can be omitted, and the configuration of the transport device 10 can be simplified. In addition, it is possible to quickly transport a predetermined amount of transported goods required on the processing device 17 side,
The transport efficiency of the transport device 10 can be further improved. Further, it is possible to contribute to effective use of resources without having to dispose of the transported material.

(10) The transported goods are sequentially discharged to the downstream transport pipe 13 while the transport apparatus 10 is operating. Therefore, there is no need to stop the operation of the transport device 10 when collecting the transported items, and it is possible to contribute to improving the transport efficiency of the transport device 10. In particular,
When transporting different types of transported goods with the same transporting apparatus 10, the transported goods can be transported continuously without having to stop the transporting apparatus 10 each time.

The above embodiments may be modified as follows. In the above embodiments, the inflow air may be sucked only from the air vent hole 30. That is, the suction from the first sub suction path 31, the second sub suction path 32, or the outside air suction path 33 may be omitted. The combination of the suction paths 31 to 33 can be arbitrarily changed on the assumption that the inflow air is sucked from the air vent hole 30. Further, the first and second sub suction paths 3
The suction portions 1 and 32 can be appropriately changed. For example, the inflow air may be sucked from the connection cylinder 24 located near (above) the intake port 23b. Further, the number of suction sites is not limited.

In each of the above embodiments, the suction fan 18 is provided as the suction means, but the type is not limited as long as the device can suck the inflow air. For example, a suction pump may be used.

In the above embodiments, the suction fan 1
The number of rotations of the suction fan 1 is not specified.
The number of rotations of 8 is appropriately changed depending on the type (specific gravity or the like) of the transported object to be transported.

In the above embodiments, the hopper 16
