It includes.

The filter F of the exhaust gas flue reduction device is installed in, for example, a smoke purification device mounted on an exhaust system of a diesel vehicle to filter soot particles. The filter (F) has a substantially cylindrical shape and forms various sizes and shapes according to the type. The filter (F) is a state in which the exhaust hole formed in the filter (F) is clogged while the soot particles are accumulated and fixed by the continuous exhaust gas filtration.

The heating unit 10 heats and filters the soot particles fixed to the filter F by applying heat to the filter F having the soot particles accumulated therein. The heating unit 10 is composed of a housing 12, the door 14 is installed so that the filter (F) can be built.

The temperature of the heat source applied to the filter F through the heating unit 10 may be about 300 ° C to 1200 ° C. When heat is supplied to the filter F in the enclosure 12, the soot particles fixed to the filter F are thermally expanded, and the adhesion force to the filter F is reduced by drying the soot particles themselves, thereby reducing the Separation efficiency is increased.

The main body 20 receives the filter F heated in the heating unit 10 to remove the soot particles adhered to the filter F.

The main body 20 is in the form of an inner empty box, forming a sealed structure so that the soot particles removed from the filter F are not scattered to the outside. At one end of the main body 20, an entrance 24 for charging and discharging the filter F into the main body 20 is formed, and a door 26 is provided at the entrance 24 so that the entrance 24 may be provided if necessary. ) Will open or close. In addition, a sealing pad (not shown) may be further installed at the doorway 24 to maintain the airtightness with the door 26.

The base plate 22 in which the filter F is placed is provided in the main body 20. The base plate 22 is installed to be movable along the inside of the main body 20.

The lower part of the main body 20 is provided with a transfer duct 28 to which the soot particles removed from the filter (F) is dropped and transported. The transfer duct 28 communicates with the inside of the main body 20 and forms a downwardly inclined structure toward the opposite end from the main entrance 20 of the main body 20.

The dust treatment unit is connected to the lower end of the transfer duct 28 to suck and process the dust dropped into the transfer duct 28.

The dust collecting part is installed on the suction line 30 connected to the lower end of the main body 20, the suction fan 32 connected to the suction line 30 to provide suction pressure, and installed on the suction line 30. Cyclone 34 for collecting and separating particles, a bag filter 36 disposed at a rear end of cyclone 34 along the suction line 30 to collect and collect particulate matter, and the cyclone 34 and bag filter 36 It is connected to the) includes a processing unit for processing the collected soot particles.

The suction duct 28 connected to the suction line 30 is subjected to the suction pressure by driving the suction fan 32, so that the soot particles dropped from the filter F to the transfer duct 28 are transferred to the suction line 30. Are conveyed accordingly.

In this process, the soot particles are collected by first passing through the cyclone 34 installed in the suction line 30, and the fine dust not collected in the cyclone 34 is secondly collected while passing through the bag filter 36. Is processed.

The soot particles collected by the cyclone 34 and the bag filter 36 can be easily collected and processed through a treatment unit connected to the lower end.

To this end, as shown in Figure 2, the processing unit is connected to the cyclone 34 and the back filter 36, the transfer pipe 40 for transferring the collected soot particles, and installed in the transfer pipe 40 Transfer screw 41 for moving the soot particles, the transfer pipe 40 is installed at the front end of the transfer screw 41 is connected to the transfer screw 41 to rotate the transfer screw 42, the transfer pipe 40 is connected to the end And a riser tube 43 for moving the soot particles discharged from the transfer pipe 40 upward, a transfer screw 44 installed in the riser tube to move the soot particles, and a transfer motor installed at the tip of the riser tube to rotate the transfer screw. 45, the discharge pipe 46 is communicated with the upper end of the riser 43 to discharge the soot particles.

The discharge port 46 is provided with a damper 47 for opening and closing the discharge port, and blocks the discharge port 46 to block the outside air from flowing backward through the transfer pipe 40 except for the treatment of the soot particles. Dampers are also provided at the lower ends of the cyclone 34 and the bag filter 36 connected to the transfer pipe 40 to block backflow of soot dust if necessary.

Thus, the operator combines the storage bag 48 and the like to contain the soot particles in the discharge port 46 and operates the transfer motors (42,45) installed in the transfer pipe 40 and the riser 43, the soot particles. Can be transported. When the feed screws 41 and 44 rotate as the feed motors 42 and 45 are driven, the soot particles are moved from the feed pipe 40 to the ascending pipe 43 along the feed screw and moved to the upper part of the rising pipe to discharge the outlet. In 46 it is stored in the storage bag (48). Therefore, the operator can simply process the soot particles by treating the storage bag 48 when it is filled.

Here, the damper installed in the outlet 46 is kept closed when the suction fan 32 is driven for the filter F cleaning operation, and is opened during the dust treatment operation.

As such, by connecting the transfer pipe 40 to the cyclone 34 and the bag filter 36 to transfer the collected soot particles through the driving of the transfer screws 41 and 44, the conventional worker manually transfers the soot particles. This can reduce the inconvenience of handling and minimize the scattering of contaminants generated during the transfer process.

Control dampers (35, 37) may be further installed to be introduced into the interior. In the conventional structure, when the suction fan 32 of the dust collecting unit is driven, a high pressure vacuum is formed in the main body 20. Too large a vacuum pressure causes power consumption and a shortened life of the suction fan 32. In addition, as the flow rate of the air flowing through the dust collector is low and the flow velocity is lowered, soot particles are not collected smoothly, and soot particles are deposited on each part of the apparatus. Therefore, the apparatus of the present embodiment is provided with a control damper (35.37) for the air inflow as described above to properly adjust the vacuum pressure inside the main body 20 and the dust collector, thereby preventing the accumulation of soot dust and efficient dust collection. The control damper 35.37 may be a structure that is open in accordance with the vacuum pressure inside the main body 20 due to the driving of the suction fan (32). In addition, the control dampers 35 and 37 may have a check valve structure that allows air to flow in only one direction, and may have a structure that allows only outside air to flow into the main body 20.

3 shows the internal structure of the main body 20. As shown in FIG. 3, the blasting unit 60 and the nozzle ring unit 70 connected to the doorway 24 are continuously disposed in the main body 20. The filter F is placed on the base plate 22 provided in the main body 20, and the blasting part 60 and the nozzle ring part () at the entrance and exit 24 of the main body 20 according to the movement of the base plate 22. 70).

As shown in Figure 4, the base plate 22 is a rectangular frame structure, the center of the rectangular frame in a structure that is penetrated so that the dust falling from the filter (F) falls to the transfer duct 28 at the bottom of the main body 20 It is. The upper portion of the base plate 22 is rotatably installed a rotary ring 80, the filter (F) is placed. Detailed description of the rotary ring 80 will be described later. The base plate 22 is moved from the doorway 24 to the blasting unit 60 and the nozzle ring unit 70 according to the driving of the transfer unit provided in the main body 20.

In order to smoothly move the base plate 22, a driving wheel 23 placed on the lower end of the main body 20 and rolling may be installed at the lower end of the base plate 22. In addition, the guide bar 25 may be installed in the longitudinal direction of the main body 20, and a guide roll 27 guided over the guide bar may be installed at the lower end of the base plate 22. The base plate 22 smoothly moves inside the main body 20 through the driving wheel 23 or the guide roll 27, thereby blasting the filter F loaded on the base plate 22. And move to the nozzle ring unit 70.

The moving part is a chain which is connected to the base plate 22 and spans the driving sprocket 50 and the driven sprocket 52 and the driving sprocket 50 and the driven sprocket 52 which are installed at both sides of the main body 20. 54, a drive motor 56 connected to the drive sprocket 50 to rotate the drive sprocket 50.

Accordingly, the base plate 22 movably installed in the lower part of the main body 20 is pulled by the chain 54 moving in accordance with the driving of the driving motor 56, and thus the doorway 24 and the nozzle ring unit 70 along the main body 20. ) To move between them.

The chain 54 is interposed between the driving sprocket 50 and the driven sprocket 52 which are spaced apart, and both ends thereof are coupled to the base plate 22 located between the driving sprocket 50 and the driven sprocket 52. Thus, as the chain 54 moves, the base plate 22 connected with the chain 54 moves between both sides of the main body 20.

As the base plate 22 moves, the filter F is cleaned while sequentially passing through the blasting unit 60 and the nozzle ring unit 70 which are continuously arranged in the main body 20.

5 to 7 illustrate the structures of the blasting unit 60 and the nozzle ring unit 70.

As shown in FIG. 5, the blasting unit 60 is installed in communication with the upper portion of the main body 20 to spray the compressed air to the filter (F), the high-pressure hose (61) to the injection cone (61) 62 is connected to the blasting tank 63 for supplying compressed air, and a diaphragm valve 64 for controlling the discharge of compressed air in the blasting tank.

The high pressure hose 66, which is installed in the high pressure hose may include an adapter 67 for connecting a different type of filter to the high pressure hose.

The blasting unit 60 separates the soot particles from the filter (F) by spraying compressed air to the filter (F) to which heat is applied.

The injection cone 61 forms a square cone shape in which the diameter increases toward the lower end. The spray cone 61 is installed in communication with the upper end of the main body (20). The high pressure air jetted from the injection cone 61 is injected into the filter F located under the injection cone 61 in the main body 20.

A high pressure hose 62 is installed at an upper end of the injection cone 61, and a blasting tank 63 and a diaphragm valve 64 are connected to the high pressure hose 62. The high pressure compressed air stored in the blasting tank 63 is instantaneously supplied according to the driving of the diaphragm valve 64 and injected into the filter F through the injection cone 61. In the present embodiment, the blasting unit 60 removes soot particles by spraying compressed air to the filter F at a pressure of 3 to 8 kg / cm 2 as the diaphragm valve 64 is driven. The compressed air pressure applied to the filter F can be variously set and is not particularly limited.

The blasting tank 63 may receive and store compressed air through a separate compressor or compression tank 68. The blasting tank 63 temporarily stores air to maintain a uniformly high pressure state, and reduces pulsation caused by air intermittently supplied from a compressor or a compression tank to obtain a uniform flow rate.

In this embodiment, the blasting unit 60 is a separate auxiliary diaphragm valve 65 and the high pressure hose 66 and the adapter so that the blasting unit 60 can also be used for other types of filters, for example, filters used in two types of smoke reduction devices. (67) is provided. The adapter 67 is a structure for coupling the two types of soot reduction filter with the high pressure hose (66). The adapter 67 may be prepared in various ways according to the type of filter and used according to the filter. The auxiliary diaphragm valve 65 has a structure for supplying compressed air at a pressure suitable for the filter for the two types of soot reduction devices. If necessary, by connecting the filter for the two types of smoke reduction device to the adapter 67, and driving the auxiliary diaphragm valve 65, it is possible to blast the filter for the two types of smoke reduction device to remove the soot particles.

In this way, not only one type of filter but also another type of filter can be cleaned through one apparatus.

The filter F passed through the blasting unit 60 is transferred to the nozzle ring unit 70 disposed next to the blasting unit 60 as the base plate 22 moves to remove residual soot particles.

As shown in FIG. 6 and FIG. 7, the nozzle ring unit 70 is disposed above the main body 20 toward the filter F to inject air, and the injection tube 71. It includes a position moving part for moving the filter F toward the center from the outside of the filter (F), and a rotating part for rotating the filter (F) placed on the base plate (22).

The position moving part is disposed horizontally on the upper portion of the filter (F) and extends in the center direction toward the outside of the filter (F), and is installed on the feed screw shaft (72) to transfer the feed screw shaft (72). The moving block 73 is moved along and the injection pipe 71 is installed, and the forward and reverse motor 74 is connected to the feed screw shaft 72 to rotate the feed screw shaft 72.

In addition, the rotating part is rotatably installed on the base plate 22 and the rotating ring 80, the filter (F) is seated on the top, and a fixed chain 81 is installed along the outer circumferential surface of the rotary ring 80, The sprocket 82 is installed on the inner surface of the main body 20 and selectively coupled to the fixed chain 81 of the rotary ring 80 according to the movement of the base plate 22, and the sprocket 82 is rotated and driven. It includes a rotary motor 83 to make.

The coupling structure of the rotary ring 80 and the base plate 22 is well illustrated in FIG. The rotary ring 80 is formed of a circular ring structure with a corresponding size so that the filter (F) can be placed, a plurality of ribs 84 are connected through the center and open between the ribs so that the soot particles can fall. It is supposed to be.

A fixed chain 81 is continuously installed on the outer circumferential surface of the rotary ring 80. In addition, a coupling sprocket 82 is installed at a position corresponding to the fixing chain 81 on the inner surface of the main body 20 so that the base plate 22 provided with the rotation ring 80 moves toward the nozzle ring portion 70. When the fixed chain 81 of the rotary ring 80 is engaged with the coupling sprocket 82. As shown in FIG. 7, the coupling sprocket 82 is connected to the rotary shaft of the rotary motor 83 via the sprocket 85 and the chain 86 to rotate according to the driving of the rotary motor 83. .

Thus, the nozzle ring portion as the injection pipe 71 moves toward the center from the outside of the filter (F) in the state in which the filter (F) placed on the rotary ring 80, the filter (F) Finally, the soot particles remaining in the will be removed.

A cover 77 covering the injection pipe 71 and the position moving part is installed at the upper end of the main body 20 so as to be openable and openable. In the present embodiment, the cover 77 is made of a transparent material, so that the worker can observe the state of the filter F inside the main body 20.

The injection pipe 71 is installed in the moving block 73 and is disposed in the vertical direction from the top of the filter F toward the filter F. The hose which is connected to the injection pipe 71 and supplies high pressure air is extended to the outside of the main body 20 and is connected to a compressor or a compression tank for supplying compressed air.

The stationary motor 74 is installed inside the main body 20, and the bevel gears 75 for power transmission are installed at the front end of the feed screw shaft 72 and the rotary shaft end of the stationary motor 74, respectively. All. Thus, when the forward and reverse motor 74 is rotated forward or reverse, the feed screw shaft 72 is rotated through the bevel gear, so that the moving block 73 screwed to the feed screw shaft 72 is the feed screw shaft 72. Will move along. A guide bar 76 is installed in parallel with the feed screw shaft 72 and the movable block 73 is guided along the guide bar 76 through the guide bar.

Here, the feed screw shaft 72 is disposed in the center direction from the outside of the filter (F), so that the moving block 73 moves between the outside and the center of the filter (F). Accordingly, the injection pipe 71 installed in the moving block 73 injects high pressure air into the filter F while moving from the outside of the filter F to the center.

In FIG. 6, reference numeral 78 is a lower injection pipe disposed at the bottom of the filter F to inject high-pressure air. The lower injection pipe 78 is capable of injecting a high-pressure air in a radial shape in the radial direction of the filter in a wide fan shape to inject air to the lower front surface of the rotating filter. The soot particles and the dirty foreign substances remaining in the lower part of the filter are removed by the air injected from the lower injection pipe.

As shown in FIG. 7, in this embodiment, the moving direction of the injection pipe 71 is set in a direction moving from the outer surface of the filter F toward the center.

By moving the injection pipe 71 as described above, after the blasting unit 60 passes through the blasting process in a state in which the heat does not cool, it is possible to clean the outer portion of the filter F, which is not relatively cleaned, before the center portion. The cleaning efficiency can be maximized.

In addition, the rotating part is configured to increase the rotational speed of the rotary ring 80 as the injection pipe 71 moves toward the center from the outside of the filter (F).

Therefore, the angular velocity of the filter F with respect to the injection pipe 71 can be kept constant regardless of the position of the injection pipe 71 with respect to the filter F. FIG.

When the filter F rotates at the same speed, the angular velocity at the outside of the filter F and the angular velocity at the center of the filter F are not the same. The angular velocity of the filter F becomes smaller as it goes from the outer portion to the center portion. In other words, the angular velocity is dependent on the diameter of the rotor. When the filter F is rotated at the same speed irrespective of the position in the filter F according to the movement of the injection tube 71, the angular velocity of the filter with respect to the injection tube 71 at the corresponding position is determined at the outer portion of the filter. It will be the largest and smaller towards the center of the filter. In this case, since the filter passes through the injection pipe 71 at a relatively high speed, the cleaning cannot be performed properly from the center portion.

Thus, as described above, the rotating part of the device has a structure in which the rotational speed of the rotary ring 80 is interlocked and decremented according to the position of the injection pipe 71. That is, the rotary motor 83 of the rotating part has the lowest speed when the injection pipe 71 is outside the filter F, and has a structure of increasing the rotational speed of the rotary ring 80 as it moves to the center. have. Therefore, when the injection pipe 71 is in the outer portion of the filter, the rotational speed of the filter F is slowed, so that the angular velocity of the filter F relative to the injection pipe 71 becomes relatively low, As the rotational speed of (F) increases, the angular velocity of the filter with respect to the injection pipe 71 becomes relatively high.

Therefore, the angular velocity of the filter F is relatively lower or higher depending on the position of the injection tube 71 so that the filter F is rotated at the same linear velocity with respect to the injection tube 71 regardless of the position of the injection tube 71. You can do it.

As such, as the filter F is rotated while maintaining the filter F at the same angular velocity with respect to the injection pipe 71, it is possible to increase the cleaning efficiency at the outside of the filter F and to remove the soot particles as a whole.

While the illustrative embodiments of the present invention have been shown and described, various modifications and alternative embodiments may be made by those skilled in the art. Such variations and other embodiments will be considered and included in the appended claims, all without departing from the true spirit and scope of the invention.
