Description

[Detailed description of the device]

[0001]

[Industrial applications]

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

[0002]

[Prior art and its problems]

 Conventionally, as a system for concentrating and collecting dust generated in residential areas and rail cars in one place, air transportation pipes have been installed along roads and railroad tracks, and the air transportation pipes have dust collection at predetermined intervals. A waste input device has been proposed in which input boxes are provided, and the waste input from each input box is sucked and pressure-fed to a waste 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 transfer pipe, air transfer is performed. There is a problem that the pipe is clogged.

Further, in the structure in which dust is temporarily stored in the dust throwing box, when a large amount of dust bags and dust are thrown into the throwing box at one time, clogging occurs inside the throwing box and the dust is transferred to the air transport pipe. There is a problem that it becomes impossible to send out the garbage in the above, or there is a problem in the detection of the level meter that detects the amount of garbage stored in the input box.

Therefore, an object of the present invention is to provide a dust throwing device which can eliminate clogging of dust bags and dust inside the air transport pipe and the dust throwing box and can perform stable dust throwing and air transport.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the first means of the present invention comprises an air transport pipe and a dust input box whose lower part is connected to the air transport pipe, and a dust input port is provided at the upper part of the dust input box. In a dust throwing device provided with a dust passage for moving dust from the throwing port toward the air transport pipe inside the throwing box, in the dust passing route, a bag breaking drum rotating in the moving direction of dust in the pass. And a gap adjusting member that moves toward and away from the bag breaking drum, and a plurality of bag breaking claws are provided on the peripheral surface of the bag breaking drum and the surface of the gap adjusting member, respectively. The structure is such that a damper means for urging the adjusting member in the direction approaching the bag breaking drum is connected.

A second means is to provide a plurality of bag-breaking blades, a part of which is exposed inside the dust passage, in the dust passage so that the cutting edges are along the moving direction of dust in the dust passage, Each of the bag breaking blades is configured to be rotationally driven in the moving direction or the reverse direction of dust.

In the above first and second means, a dust discharge valve that opens and closes the connecting portion between the dust input box and the air transport pipe may be provided.

[0009]

[Action]

 In the first means, the dust bag loaded in the dust throwing box is bitten by the bag breaking blade of the bag breaking drum in the dust passage and sent toward the gap adjusting member. Then, due to the relative speed difference between the bag-breaking claw of the drum that is about to rotate and the bag-breaking claw of the fixed gap adjusting member, the dust bag is compressed and cut into pieces, and the dust is separated. By the feeding action of the rotating bag-breaking drum, the separated pieces of dust are sent to the dust storage part of the input box and the air transport pipe by a fixed amount.

Further, in the above structure, when the biasing force of the damper means with respect to the gap adjusting member is changed, the compressive force applied to the dust bag between the adjusting member and the bag breaking drum is changed, and the bag breaking force of the dust bag is changed. Can be made

On the other hand, in the second means, while the dust bag passes through the dust passage, the dust bag is torn by the bag-breaking blade exposed in the dust passage, and the dust is separated. Moreover, the guide action of the bag-breaking blade that rotates in the normal direction of the dust is sent to the storage part of the throw-in box and the air transport pipe in a fixed amount, thus preventing clogging.

[0012]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 to 4 show a first embodiment. In the figure, 1 is an air transport pipe, 2 is a dust input box standing from the air transport pipe 1, and a dust input port 3 that is opened and closed by a door is formed above the dust input box 2. ..

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. A dust discharge valve 6 that opens and closes the connecting portion 5 between the charge box 2 and the air transport pipe 1 is provided at the lower end of the charge box 2, and a storage chamber 7 for temporarily storing dust is provided above the dust discharge valve 6. Are formed. Here, 8 in FIG. 1 is an electric cylinder for sliding the dust discharge valve 6 in the horizontal direction.

A bag breaking drum 10 is rotatably attached to the upper surface of the dust passage 4 on the inlet side via a rotary shaft 9. The bag breaking drum 10 is formed such that the longitudinal dimension of the drum is approximately the same as the width dimension of the dust passage 4, and a motor (not shown) connected to the rotary shaft 9 moves the dust in the dust passage (see FIG. 1). It is designed to be rotated in the direction of the arrow). Further, on the outer peripheral surface of the bag breaking drum 10, a large number of bag breaking claws 11 each having a sharp tip are attached.

On the other hand, below the bag breaking drum 10, a gap adjusting member 13 is attached by a fulcrum shaft 12 so as to be vertically rotatable. An arm 14 is attached to the fulcrum shaft 12 of the gap adjusting member 13, and the tip of the arm 14 is biased in a direction of approaching the bag breaking drum 10 by rotating the gap adjusting member 13 upward. The hydraulic damper 15 is connected. Further, on the surface of the gap adjusting member 13, a large number of bag breaking claws 16 having sharp tips are attached so as to face the bag breaking drum 10.

In the dust throwing device having the above structure, as shown in FIG. 4, when the dust bag A containing the dust is thrown in through the throwing port 3, the bag breaking claws 11 of the rotating bag breaking drum 10 are moved. It bites into the dust bag A and feeds the bag bag A toward the gap adjusting member 13 while making a hole in the bag surface.

In this case, since the gap adjusting member 13 is in the state of approaching the bag breaking drum 10 due to the urging force of the hydraulic damper 15, the dust bag A sent by the bag breaking drum 10 is separated from the drum 10 and the gap adjusting member 13. The dust bag A is compressed by the relative speed difference between the bag-breaking claw 11 of the bag-breaking drum 10 that is about to rotate and the bag-breaking claw 16 of the gap adjusting member 13 that is in the fixed state. It For this reason, the dust bag A is torn between the two bag-breaking claws 11 and 16, and the dust is separated.

In this case, since the dust bag A is fed toward the gap adjusting member 13 by a constant amount by the feeding action of the rotating bag tearing drum 10, the dust that has been broken up together with the broken bag is kept constant. The quantity will be dropped and stored in the storage chamber 7 of the charging box 2.

When the storage chamber 7 is filled with dust, the dust discharge valve 6 is opened to drop the dust into the air transport pipe 1, and the dust is suction-fed to the dust storage container or the like by the pressure of air.

Further, in the above case, if the pressure of the hydraulic damper 15 urging the gap adjusting member 13 upward is changed, the compressive force between the adjusting member 13 and the bag breaking damper 10 changes. The breaking force against the dust bag A can be adjusted. It should be noted that other hydraulic damper means such as an air damper or a spring may be used as the hydraulic damper 15 described above.

On the other hand, FIGS. 5 to 7 show a second embodiment. In this example, a large number of circular bag-breaking blades 20 are provided on the side wall and the end wall of the dust storage chamber 7 of the dust input box 2 so that a part of the blades are exposed inside the dust storage chamber 7. There is. Each of the bag breaking blades 20 has a cutting edge 21 on its peripheral surface attached along the direction of movement of dust in the dust passage 4 (vertical direction in the storage chamber 7), and the cutting edges 21 face each other. It is located in. The cutting edges 21 may be arranged in a staggered pattern.

The bag breaking blades 20 are connected to motors 24 and 25 via drive shafts 22 and 23, respectively, and the driving of the motors 24 and 25 causes the direction of movement of the dust in the dust passage 4. Alternatively, it is adapted to rotate in synchronization with the opposite direction.

The cutting edge 21 of each of the bag breaking blades 20 is formed by sharpening the outer peripheral edge of the disk into a sharp shape, but since the cutting edge has no eyes, it is a waste bag such as a plastic bag. However, it can be cut without getting caught. In addition, for a waste bag such as a paper bag which is less likely to be caught by the blade, the cutting blade 21 of the bag breaking blade 20 may be formed with a marked blade.

In the dust throwing device having the above-mentioned structure, when throwing dust, the dust discharge valve 6 is closed and the thrown dust bag A is temporarily stored in the dust storage chamber 7. Then, when the storage chamber 7 becomes full and the dust is transported by air, the dust discharge valve 6 is opened and at the same time, the bag-discharging bag discharges 20 are rotated to break the garbage bag A and disassemble the garbage. Discharge to the air transport pipe 1.

In this case, when each of the bag breaking blades 20 is rotated in the moving direction of the dust, that is, from the upper direction to the lower direction, the feeding action of each bag breaking blade 20 forcibly cuts the dust by a fixed amount. Can be sent to. On the contrary, when each bag-breaking blade 20 is rotated in the direction opposite to the moving direction of the dust, the falling of the dust is stopped by the rotation of the bag-breaking blade, so that the dust is gradually added to the air transport pipe 1. It can be discharged quantitatively.

On the other hand, FIG. 8 shows a third embodiment, and in this example, a large number of bag breaking blades 20 are attached opposite to both side walls of the storage chamber 7 of the dust input box 2.

The bag-breaking blade 20 is attached near the entrance of the dust passage 4, and when the bag bag A is loaded from the loading port 3 at the same time, the bag-breaking blade 20 breaks the bag to separate the dust. May be stored in the storage chamber 7.

[0028]

[Effect of the device]

 As described above, the dust throwing device of the present invention breaks the thrown dust bag inside the dust passage and sends the dust to the dust storage chamber and the air transport pipe in the state of being broken up. It is possible to reliably prevent clogging of the air transport pipe.

Further, since the dust can be sent out in a fixed amount by the feeding action of the rotating bag-breaking drum and the blade of the bag-breaking blade, there is an effect that the dust can be stably discharged and collected.
