Abstract

(57) [Summary] [Purpose] Prevents clogging of waste separator bottoms by pneumatic transportation. [Structure] A bypass circuit 6 is provided in a pipe line 5 connecting the separator 1 and the dust collector 3, the bypass circuit is connected to the compactor portion 21 of the dust discharge device 2, and the bypass circuit is periodically opened to descend into the separator. Create a flow and forcefully discharge dust to the compactor section.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing clogging of waste in the lower part of a separator in a pneumatic transportation system for waste.

[0002]

2. Description of the Related Art A centralized waste treatment system using air transportation pipes has been put into practical use in some areas and facilities, and the waste transported through the pipes is separated by a separator in a collection center as shown in FIG. The waste 10 is transported to the separator 1 and separated into waste and air by the separator 1, and the waste 10 is further compressed by the waste discharging device 2 connected to the lower part of the separator 1 and then transported by container. The fine dust 10 a that is not separated by the separator 1 is separated by the dust collector 3 and collected by the separator 1. The air from which the dust 10a has been separated by the dust collector 3 is finally deodorized and then released into the atmosphere. The air flow in the pipeline is created by the blower 4,
This air stream is loaded with dust and transported.

The separator 1 is generally composed of a cyclone, and a level meter LL and L for detecting the lower limit and the upper limit of the amount of waste stored in the discharge pipe 11 below the separator.
H is installed. Further, the dust discharging device 2 communicated with the lower portion of the separator 1 via the discharge pipe 11 is composed of a compactor portion 21 formed of a hydraulic cylinder and a container portion 22 connected to the front thereof. When the low level meter LL is turned on during the transportation of the waste, the compactor unit 21 is continuously operated back and forth to compress the waste and send it to the container unit 22. On the other hand, if the high level meter LH is turned on, the transportation of waste will be stopped.

[0004]

However, in the conventional structure as described above, when the amount of transported dust increases, the low level meter LL is turned on and the high level meter LH is turned on while the compactor section 21 is moving forward. Therefore, the transportation of garbage is interrupted. Therefore, dust may be entangled in the lower part of the separator 10 and may be blocked. In this case, since the dust cannot be separated, it cannot be restarted unless the separator 10 is disassembled and cleaned. Further, in the case where the high-level meter LH is not provided, the waste is gradually stored in the separator 1, so that a part of the waste is blocked and a similar situation occurs.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a blockage preventing device for preventing blockage of the lower part of the separator due to dust.

[0006]

In order to achieve the above object, a blockage prevention device according to the present invention is provided with a bypass circuit in a pipe line connecting a separator and a dust collector and connected to a compactor section. Is opened periodically to create a downward flow in the separator.

[0007]

Since a downward flow is generated in the separator by periodically opening the bypass circuit, it is possible to prevent the lower part of the separator from being blocked.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic configuration diagram showing an embodiment of the present invention, in which 5 is a separator 1 and a dust collector 3 downstream thereof.
And 6 is a bypass circuit that connects the conduit 5 and the compactor portion 21, and is provided with an opening / closing valve 7. Reference numeral 8 is a main opening / closing valve provided in the conduit 5. The other structure is the same as that of the conventional example shown in FIG.

The bypass circuit 6 is used as an auxiliary, and normally, the waste is transported and treated with the pipeline 5 opened and the bypass circuit 6 closed. Then, the bypass circuit 6 is opened periodically, and the pipeline 5 is closed at this time. Then, since the downflow a is generated in the separator 1, the downflow a forcibly discharges the dust 10 in the separator 1 to the compactor portion 21, so that the lower part of the separator 1 can be prevented from being blocked. it can. The blocking prevention operation by the bypass circuit 6 may be performed during a period other than the time period for transporting the refuse.

[0010]

As described above, according to the present invention, a downward flow is regularly created in the separator through the bypass circuit to forcibly discharge the dust to the compactor section, so that the lower part of the separator is blocked. There is an effect that can be prevented.
