Description

[Detailed Description of the Invention] The present invention relates to a device for pneumatically transporting and treating garbage generated from the cabin of a railway vehicle.

Garbage generated from the cabins of railway vehicles is normally disposed of by enclosing it in garbage bags and transporting it on an attached conveyor line, but this method is not preferred from a hygiene perspective and because it does not emit a bad odor to the surrounding area. It's not more than 1.

In response to this problem, pneumatic transport systems have recently been adopted.

As shown in the flowchart shown in Figure 1, a common method is to connect a blower 3 to a transportation pipe 2 that has a number of garbage input ports 1 corresponding to the entrances and exits of the vehicle, and to blow air in through the blower 3. The dust taken in from the foot valve 4 and conveyed by suction through the air transport pipe 3 is separated from the air by a dust collecting hole 5, and taken out from the continuous dust discharge device 6.1. On the other hand, Bang filter 7
Dirt and dust are removed from the separated air, deodorized by a deodorizer 8, and released into the atmosphere.

However, in recent years, there has been a trend to reduce the waste disposal time as much as possible, especially in order to improve the operational efficiency of vehicles, and it has become common practice to provide multiple transport pipes 2 to dispose of garbage from multiple train sets at the same time. Moreover, the reliability of this equipment is required to be high so that the function of this rice processing is not impaired.

However, it is difficult to route the transport pipe 2 from the garbage input location to the dust collection hopper 51 in an optimal way for air transportation, and generally there are places where the pipe 2 bends vertically, horizontally, etc.

For this reason, it is not uncommon for rice to become clogged at such curved parts.

When a blockage occurs, it takes a lot of effort and time to remove it, which becomes a problem.

The present invention was devised to eliminate the above-mentioned drawbacks, and in order to simultaneously dispose of waste from multiple train sets, multiple transport pipes are installed along the rails, and bypass pipes are installed to connect the transport pipes. The system is designed so that when the Chitsuno transport pipe becomes clogged, the waste is automatically transported through the bypass pipe and into another transport pipe.

The following explanation will be given based on FIGS. 2 to 5 showing an embodiment of the present invention. Three transport pipes 10, 11° 12
3 and are arranged parallel to each other with a platform 14 in between.

and a bypass pipe 15 connecting the transport pipe 10 and the transport pipe 11.
16 are provided with inclinations in opposite directions, and a bypass pipe 17 connecting the cut transport pipes 11 and 12 is provided with an inclination in the same direction as the bypass pipe 16.

Transport pipes 10, 11.12 and bypass pipes 15, 16゜17
A branching device 20 is provided at each connection portion.

The details of this device 20 are as shown in FIG.
. Conveyance of garbage is switched to the transport path 21 or the transport path 22 via a lever 26 provided on the shaft 24.

The operation of the cylinder 25 is automatically performed by the operation of a pressure switch 18 provided at a point A near the entrance of the dust collecting hopper 5 to detect clogging.

Next, we will explain the function of the garbage transport pipe that has been authorized in this way.

In normal times, garbage from vehicles 19 stopped on each rail 13 is thrown in from the input port 1 of each transport pipe 10, 11° 12, and is transferred to the dust collection hopper 5 without passing through the bypass pipes 15, 16° 17. transported.

In this work, all the transport pipes are not operated at the same time because the time required to transport the waste is extremely short and from the viewpoint of equipment economy, the blower 3 is operated continuously and each transport pipe is
0, 11, and 12 sequentially.

However, in areas where the transport pipes are laid out horizontally and in a straight line, is it possible for garbage to get stuck in the building?There is a bend in the part 1 leading to the dust collection hopper 5, and there may be a problem. many.

If the transport pipe 10 becomes clogged, the pressure toward point A near the dust collecting hopper 5 will change significantly, and the pressure switch 18 will operate, causing the two branches of the bypass pipe 15 communicating with the transport pipes 10 and 11 to The cylinder 25 of the device 16 is operated and the switching valve 23 of the branching device 16 is moved to connect the bypass pipe 1.
5 and transported by a transport pipe 11.

Similarly, when the transport pipe 11 is clogged, the material is transported by the transport pipe 10 through the pimes pipe 14, and when the normal transport pipe 12 is clogged, the material is transported by the transport pipe 11 through the bypass pipe 15.

In this case, the time spent pneumatically transporting the garbage is extremely short, so by operating the switching valve 23 of the branching device 16 as appropriate for the work, the garbage processing time is hardly extended.

The embodiment shown in Fig. 6 has four transport pipes 30, 31, 32° 33
In this example, the pipes 35 and 36 connecting the transport pipe 31 and the transport pipe 32 are provided so as to be inclined in opposite directions, and the bypass pipe 34 connecting the transport pipe 30 and the transport pipe 31 is arranged as a bypass pipe. 35, and transport pipe 33 and transport pipe 32.
The bypass pipes 37 connecting the pipes 36 and 36 are provided so as to be inclined in the same direction as the pie-four pipes 36, and their operation is the same as in the previous embodiment.

Note that 38 is a pillar. In the present invention, as described above, even if one of the multiple transport pipes is clogged, it is automatically and conveniently transported through the binos pipe to another transport pipe, so there is no need to stop the equipment. Garbage never gets stuck.

This means that, compared to the conventional case where a single transport pipe is provided, it can be expected that there will be fewer chances of the equipment being shut down due to waste sorting.

In addition, maintenance and inspection of transport pipes can be carried out in one case when the equipment is in operation by operating the switching valve, and furthermore, the present invention can be easily attached to existing equipment, which has great practical effects.

In the above embodiment, the bypass pipe was explained as connecting the transport pipes adjacent to each other, but the invention is not limited to this. For example, in FIG. Of course, it is also possible to provide a gas pipe.
