Hereinafter, the present invention in more detail by the accompanying drawings as follows.

1 is a longitudinal cross-sectional view showing a state of the present invention air purification device, Figure 2 is a cross-sectional view taken along the line AA 'of Figure 1 showing the air purification and compressed air filling action, Figure 3 is A- It is explanatory drawing which shows the air sent to air outlet from the air purification chamber by sectional drawing line A ', and FIG.

The air inlet blocking guide (H1) is used to cut off loads during train separation or emergency braking, block power generation, block braking pipes, and remove salsa (scattered sand on railway rails by spraying compressed air through drains for dirt discharge). To increase the coefficient of friction between the vehicle and the vehicle.The vehicle is automatically operated so that it can be stopped at short distances for the safety of the power car and all trains when sudden braking is engaged, and the power car braking side (not shown) is not located in the emergency braking position. If not, protect the train by avoiding slow recovery.

The air pressure at the operation position of the railroad car is supplied to the lower chamber G of the blocking piston P2 through the main air engine 50 of the power vehicle, and flows to the groove B on the center of the circumferential surface of the working piston P1. Pressure air of the braking tube 1 is supplied from the upper chamber C of the working piston P1 to the volume air cylinder 100 connected to the working piston P1 through the lower chamber D gradually through the sleeper port P12. It is also supplied to the upper spring chamber (Y) of the working piston (P1).

When the braking valve (not shown) suddenly depressurizes the braking tube 60 due to an emergency position, train separation, or hose rupture, the pressure applied to the upper chamber C of the working piston P1 through the braking tube 60. The air is immediately discharged and the pressure air of the volume air cylinder 100 connected to the lower chamber D of the working piston P1 cannot be discharged at the same speed as the brake tube 60 pressure by the sleeper port P12. ) The upper and lower air pressures are different.

As a result, the working piston P1 pushes the return spring P14 above the working piston P1 and rises. The air pressure of the main air pipe 50 that has flowed up to the groove B is connected to the salsa volume air pipe 70 and supplied to the upper chamber E of the blocking piston P2.

At this time, the main air engine 50 is connected to the load blocking power generation braking cutoff tube 80 by the groove F of the blocking piston P2, and the pressure air is supplied to block the load and the power generation braking.

On the other hand, the pressure air of the working piston (P1) is not discharged to the braking tube (60), but is slowly discharged to the sleepiness port (P12), after about 10 seconds or more, the working piston (P1) to the upper return spring (P14) Is automatically returned.

If the volume air cylinder 100 connected to the working piston P1 becomes weaker than the return spring P14 pressure of the working piston P1 after a predetermined time, the working piston P1 returns and the salsa is cut off.

However, the pressure air supplied to the upper chamber E of the blocking piston P2 while the working piston P1 is acting causes the blocking piston P2 to act downward and the grooves F excavated in the blocking piston P2. The pressure air of the main air engine 50 is supplied to the load blocking power generation braking cutoff tube 80 while pushing the cutoff reverse direction H2 and supplying it to the braking pipe cutoff tube 90 to supply a cutoff valve (not shown). Close it.

In order to return the blocking piston P2 even when the working piston P1 is returned from the above, the braking valve (not shown) must be placed in the emergency position so that the emergency pipe 62 is opened to push the selective stationary valve H3 and the blocking piston P2. To the lower chamber (G) to return the blocking piston (P2).

At this time, the upper chamber (E) of the blocking piston (P2) is through the salsa sleepiness sphere (P12) there is no resistance due to the return. When the blocking piston (P2) is returned to the same position as the operation position, the load and the generation braking block is also returned.

Referring to the effect of the present invention is as follows.

Air pumped to the air inlet 2 hits the outer wall of the primary air purifying chamber 4, causing vortexing in the air vortex chamber 5, and dust or moisture contained in the air is caused by centrifugal force. Falling to the lower part of (5) and accumulated in the waste collection chamber (9) and the air is filtered through the filter (3) of the primary air purification chamber (4), the secondary of the secondary air purification chamber (7) The filter is filtered again while passing through the filter (3) to be further purified, and then the air is discharged to the volume air cylinder (100) of the railway vehicle through the air outlet (8) connected to the second air purification chamber (7) The same air purification function is the same as in the original application design.

On the other hand, when the air purification function is performed as described above, the high-pressure air flowing into and purged into the second air purification chamber 7 is blocked by the reverse displacement V1 formed in the passage 20 and the reverse displacement V2 is installed. It is supplied to the compressed air storage chamber 30 on the right side of the piston 10 through the supply pipe 32 to move the piston 10 to the left.

According to the left side movement of the piston 10, the opening / closing rod 13 is also moved to the left side to open and open the waste outlet openings 42a, 42b, 42c, 42d, and 42e to discharge the dirt collected in the waste collection chamber 9.

The compressed air filled in the compressed air storage chamber 30 of the piston 10 is gradually supplied to the space 16 on the left side of the piston 10 through the air inlet hole 14.

After a while, when the pressure 16 of the space 16 on the left side of the piston 10 and the pressure air of the compressed air storage chamber 30 on the right side of the piston 10 become the same pressure, the springs 12, 12 ′ are elastically applied to the piston 10. ) Is pushed to the right side and the opening and closing rod 13 is also moved together so that the opening and closing holes (42a, 42b, 42c, 42d, 42e) for the discharge is closed and the discharge of the dirt is stopped.

For reference, the braking structure of a railroad vehicle generally operates the braking device by discharging air in the air transport pipe to lower the pressure, and the braking is completed in a state where the set pressure is applied by inflowing air, thereby becoming a non-braking state.

In addition, the waste discharge operation collected in the waste collection chamber 9 is performed when the braking is applied by operating the braking of the vehicle in the engine room, and when the air in the volumetric cylinder 100 is discharged to the outside for braking operation, Since air in all spaces except the compressed air storage chamber 30 is released through the air inlet 2, a large air pressure difference occurs between the compressed air storage chamber 30 and other spaces.

Accordingly, the piston 10 which has been shot by the spring 12 in the same pressure state is moved toward the space 16 having a relatively low air pressure by the air pressure of the compressed air storage chamber 30 as shown in FIG. The opening / closing rod 13 is also retracted, and the opening and closing holes 42a, 42b, 42c, 42d, and 42e for opening the waste are forcibly discharged from the waste collection chamber 9 by the force of air pressure. , The piston 10 is moved and at the same time, the compressed air in the compressed air storage chamber 30 is strongly discharged to the space 16 through the air inlet hole 14, and again passes through the reverse collection V1 of the passage 20. It is introduced into the secondary air purification chamber (7) and is blown inward from the surface of the secondary filter (6) to separate the dirt caught in the filter (6), disperse it in the air, and then move the air to communicate After entering the first air purification chamber (4), the first Out off the dirt of the emitter (3) in the same manner is discharged through the air swirl chamber 5 and the waste oil jipsil 9 a through the dirt discharge aperture for the open state (42a, 42b, 42c, 42d, 42e).

When all the air in the compressed air storage chamber 30 is discharged and the other parts and the air pressure are the same, the springs 12 and 12 'are operated to move the piston 10 and the opening and closing hole 13 to the initial state as shown in FIG. Let's go.

The cleaning operation of the filter (3) (6) is a forced discharge method using compressed air at the same time as the discharge operation of the dirt, the waste discharge is quick and the discharge is large.

In the above operation, if the area of the opening and closing port 42, which is the waste discharge passage, is increased to five times or more, or formed into a plurality of pieces 42a, 42b, 42c, 42d, and 42e as shown in FIG. In accordance with the large amount of draft emissions, the air-conditioning guide valve (H1) installed in the power car is operated, the front and rear trains are safely stopped when the train is separated.

On the other hand, when the air pressure of the braking tube 60 is suddenly discharged, the pressure air of the space 16 on the left side of the piston 10 is discharged to the atmosphere through the reverse displacement V1 and the compressed air storage chamber 30 on the right side of the piston 10 is discharged. Of the pressure air is blocked by the reverse flow (V2) of the supply pipe 32, so the piston 10 is moved to the left to open the waste opening and closing opening (42a, 42b, 42c, 42d, 42e) to remove the dirt. Discharge.

Again, the compressed air of the compressed air storage chamber 30 is supplied to the space portion 16 on the right side of the piston 10 through the air inlet pore 14, and the pressure air of the space portion 16 is the reverse displacement V1 of the passage 920. The outside is discharged to the outside through the spring (12, 12 ') by the resilience of the discharge outlet (42a, 42b, 42c, 42d, 42e) of the discharge discharge is stopped.

In this way, when the braking state is relaxed in the power vehicle, the discharge of air is stopped and high pressure is formed again. Thus, the compressed air is filled into the compressed air storage chamber 30 at the same time as the initial operation of the air to prepare for the next operation. Will be.

As described above, the present invention is used for emergency braking of trains, separation of trains or supply of pressure air, and discharge of dirt and cleaning of filters are performed with strong air pressure, and safely stops trains.

As described above, the railroad air purifying apparatus of the present invention operates the dust discharge operation at the time of supplying or braking the pressure air to supply cleaner air to the inside of the train, and to ensure braking force when the train is separated. There is an effect that the separation and connection can be easily performed.
