JPH04101903A - Judging system for choking position of refuse vacuum transportation system - Google Patents

Abstract

PURPOSE:To reduce energy required for judging a choking position by searching the choking position through a binary searching method for checking the choking position at every middle point. CONSTITUTION:For instance, when choking occures at a charging port A12, sucking operation is carried out at a charging port A8 located at a middle spot on a choked dust transporting pipe line 1 from the charging port A12 to a central facility 2 to check pressure and air quantity at the central facility 2 for judging the existance of clogging trouble in the pipe line 1. When the clogging trouble is judged, the clogging of the pipe line is checked similarly as the above case at a charging point A3 at a middle spot between the charging spot A8 and the central facility 2 for judging the existance of the clogging trouble. A clogging position can be searched by repeating the above process to shorten the working time of a blower.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a system for determining the position of occlusion in a vacuum garbage transport system.

[Conventional technology]

Conventionally, the method for determining the position of blockage in this type of vacuum garbage transport system has been to determine the position of blockage by suctioning one piece of garbage from the farthest input port into the center equipment in the event of blockage.

[Problem to be solved by the invention]

The conventional method for determining the position of blockage in the vacuum garbage transport system described above has the problem that it takes a long time to determine the position of blockage when there are nearly 200 garbage input ports in the vacuum transport system. Since the blower (approximately 800 kW blower) is operated continuously when making a determination, a large amount of power is consumed.

[Means to solve the problem]

The present invention includes a plurality of garbage input ports for inputting garbage, and an intake port provided corresponding to the garbage input ports for taking in air from the outside and creating an air flow when sucking garbage from the garbage input ports. , and a waste transport pipe that transports the waste thrown into the waste input port to a center facility connected to the terminal end by means of a vacuum generated by a blower. A blockage position for determining a blockage position when a waste vacuum transport system is blocked The determination method is characterized in that a binary search method is used to narrow down the blockage positions.

The figure is a detailed block diagram of the computer in the center facility 2 in FIG. 1.

The blockage position determination method of the garbage vacuum transport system of this embodiment is that air intake ports B1-B14 are provided corresponding to intake ports B1-B14 for taking in air and creating an air flow when sucking garbage. Garbage inlet A1 for throwing in garbage
- A14, the garbage transport pipe 1 for transporting garbage, the shutoff valves C1 to C3 for determining the route of the garbage, and the terminals of the waste transport pipe 1, which are connected to the terminal and exhaust the inside of the waste transport pipe 1. It consists of a center facility 2 that creates a vacuum, discharges the transported garbage into a container car, and further controls the garbage vacuum transportation system. Moreover, the center equipment 2 consists of the center equipment plant shown in FIG. 2 and the center equipment computer shown in FIG.

The center equipment plant shown in FIG. 2 includes a garbage separator 29 that separates waste collected through the garbage transport pipe 1 from air.
, a dust remover 6 that removes fine dust that has not been separated by the garbage separator 29, and a blower 7 that generates air flow in the garbage transport pipe 1, creates a negative pressure inside the pipe, and collects waste at a dust collection center. , a deodorizing device 8 for removing odor in the air separated from waste before it is discharged into the atmosphere, an air cooler 9 for cooling the air when it is discharged into the atmosphere, and a deodorizing device 8 for cooling the air when it is discharged into the atmosphere; an exhaust buffer box 11, an air supply buffer box 10 that creates an air flow when the dust transport pipe 1 becomes too negative pressure when the dust transport pipe 1 becomes clogged while sucking dust from the dust transport pipe 1 with the blower 7; A cyclone 30 for dropping waste, a garbage compactor 31 for compressing garbage, a container 5 for transporting garbage, and a container moving device 12 for moving the container 5 onto a container car 13. , and a container car 13 for transporting the container 5 to the garbage incineration site.

The center equipment computer in Fig. 3 has input port A (3rd
A transmission device controller 25 that monitors and controls data from A1-A14) in the figure, a sequencer circuit 27 that outputs to the center equipment plant such as a blower and garbage compression, a remote station device 26 connected to this, and a central processing unit 14. and an interface device 24 for establishing an interface between the central processing unit 14 and the transmission device controller 25 (or remote station device 26), and a LAN (LAN) for connecting between the central processing unit 14 and the interface device 24.
a local area network) 23, a central processing unit 14 that controls the entire center equipment computer, a magnetic disk drive 15 that stores garbage transportation time, garbage fees, electricity fees, and other databases, and a program that runs when starting up the system. A floppy disk device 16 for loading, a system console 17 for inputting system alarm messages and various commands, an operation console 18 for inputting commands for the entire garbage vacuum transport system, and a central control unit for monitoring and controlling the operation console 18. A processing device 21, a floppy disk device 19 for starting up the operation console 18, and a magnetic disk device 20 storing a database of pipelines or street maps of the garbage vacuum transportation system.
, a CRT and a keyboard 22 for displaying the entire garbage vacuum transport system and inputting commands.

Next, the operation of this embodiment will be explained.

In Figure 1, when a blockage (clogged with garbage) occurs at the input port A12, the center equipment 2 automatically narrows down the blockage position using a binary search method for the blockage route.

That is, when a blockage occurs when trying to put garbage into the input port A12, the operation of searching for which part of the blocked garbage transport pipe 1 from the input port A12 to the center equipment 2 is where the blockage is occurring will be explained. do. First, input port A
A suction operation is performed on the input port A8 located at the midpoint of the blocked path from the center equipment to the center equipment, and the presence or absence of a blockage is determined based on the pressure and air volume at the center.

In this judgment, if there is a blockage, then input port A8 located at the intermediate point and input port A3 located at the intermediate point between the center equipment, and if there is no blockage, then main intermediate input port A8 By performing a suction operation and determining the presence or absence of a blockage for the input port AIO located at the midpoint between the input port A12 where the blockage occurred and by repeating this, the blockage position is finally determined within the range of the input port interval.
