Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dust input device for inputting and collecting dust using pneumatic transportation.

[0002]

[Prior art and its problems]

 Conventionally, as a system for collecting dust generated in residential areas and railway cars in one place, air transportation pipes are arranged along roads and railroad tracks, and the air transportation pipes are disposed at predetermined intervals. A dust input device has been proposed in which input boxes are provided and the dust input from each input box is sucked and pressure-fed to a dust storage container through an air transport pipe.

However, in the above-mentioned waste input device, when the waste input from the input box is stored in a waste bag such as a vinyl bag or a paper bag, if the waste bag is larger than the inner diameter of the air transportation pipe, air transportation is performed. The tube may become clogged and become blocked.

[0004] Once the air transportation pipe is blocked in this manner, the transportation of dust is completely stopped. Therefore, it is necessary to investigate the blocked portion immediately and remove the transportation pipe at that portion to take out dust. Such work has a drawback that it requires a lot of labor and time and increases maintenance cost.

Therefore, an object of the present invention is to provide a dust throwing device in which a dust bag is broken inside the dust throwing box and the dust is put into the air transport pipe in a separated state. .

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention comprises an air transport pipe and a dust input box whose lower part is connected to the air transport pipe. A dust input port is provided above the dust input box, In a dust input device having a dust passage inside which moves dust from the input port toward the air transport pipe, a bag-breaking conveyor that moves the input dust into the dust passage in a substantially horizontal direction, and a breaker A gap adjusting plate that moves toward and away from the bag conveyor is provided, and a plurality of bag breaking claws are provided on the conveying surface of the bag breaking conveyor and the surface of the gap adjusting plate, and the adjusting plate is attached to the gap adjusting plate. The structure is such that the damper means that urges in the direction of approaching the bag-breaking conveyor is connected.

[0007]

[Action]

 In the above-mentioned structure, the dust bag thrown into the dust throwing box is sent horizontally by the bag-breaking conveyor and hits the gap adjusting plate to be stopped. At this time, the dust bag was compressed and broken due to the relative speed difference between the bag tearing claw of the conveyor that was about to move and the bag tearing claw of the fixed gap adjusting plate, and the dust was broken up. As it is, it is sent to the air transportation pipe.

Further, when the urging force of the damper means connected to the gap adjusting plate is changed, the compressing force applied to the dust bag between the adjusting plate and the bag breaking conveyer changes, so that the bag breaking force of the dust bag is changed. You can

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1 to FIG. 3, 1 is an air transport pipe, 2 is a trash throwing box standing from the air transport pipe 1, and a dust throwing port 3 which is opened and closed by a door above the dust throwing box 2. Are formed.

The lower part of the dust input box 2 is connected to the inside of the air transport pipe 1, and a dust passage 4 for sending dust from the input port 3 toward the air transport pipe 1 is provided inside the input box 2. Has been formed. In addition, a dust discharge valve 6 for opening and closing the connecting portion 5 between the feed box 2 and the air transport pipe 1 is provided at the lower end of the charging box 2, and a storage for temporarily storing the dust is provided above the dust discharging valve 6. A chamber 7 is formed. Here, 8 in FIG. 1 is an electric cylinder for sliding the dust discharge valve 6 in the horizontal direction.

On the upper part of the dust passage 4, there is provided a bag-breaking conveyor 9 for horizontally moving the dust bag loaded from the dust loading port 3 in a slightly upward direction. This bag-breaking conveyor 9 comprises a steel belt conveyor 10 installed on an inclined table 11 inside the dust input box 2, and one roller 12 of the steel belt conveyor 10 is connected to a driving air motor 13 to convey the conveyor 9. A large number of bag breaking claws 14 are attached to the entire surface.

A gap adjusting plate 15 is provided above the bag breaking conveyor 9 and has one end rotatably supported by a rotary shaft 16. A pin 18 that fits into a long hole 17 formed on both side walls of the charging box 2 is attached to the free end of the gap adjusting plate 15, and the pin 18 moves through the long hole 17 to adjust the gap. The front end side of the plate 15 moves toward and away from the bag-breaking conveyor 9, and hydraulic dampers 19, 19 for applying downward biasing force to the gap adjusting plate 15 are connected to both ends of the pin 18 thereof. There is.

A large number of bag-breaking claws 20 having sharp tips are attached to the surface of the gap adjusting plate 15 facing the bag-breaking conveyor 9.

In the dust throwing device having the above-mentioned structure, when the dust bag A containing the dust is thrown in through the throwing port 2, the dust bag A is received by the bag breaking conveyor 9 as shown in FIG. Then, it is sent toward the gap adjusting plate 15 by the bag breaking claw 14 of the conveyor 9.

In this case, the urging force of the hydraulic damper 19 causes the tip portion of the gap adjusting plate 15 to be in a state of being close to the bag-breaking conveyor 9, so that the dust bag A sent by the bag-breaking conveyor 9 is transferred to the conveyor 9. It can be stopped between the clearance adjusting plate 15. Then, the dust bag A is compressed by the relative speed difference generated between the bag-breaking claw 14 of the bag-breaking conveyor 9 that is about to move and the bag-breaking claw 20 of the fixed gap adjusting plate 15. Therefore, the dust bag A is torn between the bag breaking claws 14 and 20, and the dust is separated, and falls from the bag breaking conveyor 9 onto the dust discharge valve 6 and is stored in the storage chamber 7. To be done.

When a certain amount of dust is stored in the storage chamber 7, the dust discharge valve 6 is opened to drop the dust into the air transport pipe 1 and pressure-feed the air to a dust storage container or the like.

As described above, the dust bag A is broken between the bag breaking conveyor 9 and the gap adjusting plate 15, but the pressure of the hydraulic damper 19 that biases the gap adjusting plate 15 downward is changed. Since the compression force of the dust bag A between the adjusting plate 15 and the bag-breaking conveyor 9 changes, the bag-breaking force for the waste bag A can be adjusted. It should be noted that the above hydraulic damper 19 may be another damper means such as an air damper or a spring. Further, as the air motor for driving the steel belt conveyor 10, other means such as an electric motor or a hydraulic motor can be used.

[0018]

【effect】

 As described above, in the dust throwing device of the present invention, the thrown dust bag is broken inside the dust passage, and the dust is sent to the air transport pipe in pieces, thus preventing clogging of the air transport pipe. Therefore, there is an effect that stable garbage input and collection work can be performed.

Further, by changing the urging force of the gap adjusting plate with respect to the bag-breaking conveyor, the bag-breaking force of the waste bag can be adjusted, so that there is an advantage that the dust bag can be reliably broken.
