Description

Technical Field

[0001] This utility model relates to a ship exhaust gas treatment device, belonging to the field of ship exhaust gas treatment technology. Background Technology

[0002] Exhaust gas is another major contributor to air pollution. It contains carbon monoxide, nitrogen oxides, and other particulate matter that is harmful to human health, especially leaded gasoline, which poses a greater risk. Ship exhaust emissions primarily consist of NOx, HC, CO, particulate matter, and sulfides, making exhaust gas treatment crucial. Current treatment systems can purify these toxic substances using the adsorption effect of filter plates. However, because filter plates have pores, these pores are easily clogged by impurities during continuous operation. If the pores are not cleared promptly, the adsorption efficiency of the filter plate will be significantly reduced, resulting in a marked decline in the overall effectiveness of the treatment equipment in purifying toxic substances. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a ship exhaust gas treatment device, which solves the problem in the prior art that, because the filter plate has filter holes, these filter holes are easily blocked by impurities during continuous operation. Once the filter holes are blocked and are not cleared in time, the adsorption efficiency of the filter plate will be greatly reduced, and the effectiveness of the entire treatment equipment in purifying toxic substances will be significantly reduced.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution: A ship exhaust gas treatment device includes a treatment box, which is a cavity structure. An air inlet pipe communicating with the cavity structure is fixedly installed on the treatment box, and an air outlet pipe communicating with the cavity structure is fixedly installed on the treatment box. A filter plate is installed inside the cavity structure, and a scraper is installed on one side of the filter plate. A brush is fixedly installed on the scraper and abuts against the filter plate. A push rod is fixedly installed on the side of the scraper away from the brush. A positioning groove is opened on the treatment box, and a positioning plate is slidably installed inside the positioning groove. A vibration block is fixedly installed at one end of the positioning plate, and one end of the vibration block extends to the outside of the positioning groove and can abut against the filter plate. A contact plate is fixedly installed at the other end of the positioning plate, and the push rod can abut against the contact plate. A drive structure capable of driving the scraper to move is provided on the treatment box.

[0005] The present invention is further configured such that: a first spring is fixedly provided between the positioning plate and the inner wall of the positioning groove near the filter plate; the end of the contact plate facing the push rod is an arc-shaped surface, and the push rod abuts against the arc-shaped surface.

[0006] By adopting the above technical solution, the intake pipe is first connected to the external exhaust pipe. The exhaust gas enters the cavity structure through the intake pipe and comes into contact with the filter plate, allowing the filter plate to adsorb and filter the exhaust gas, effectively reducing harmful substances in the exhaust gas emissions and lowering the degree of air pollution. When the filter plate needs to be cleaned later, the drive structure is activated to rotate the scraper. The scraper then drives the brush to clean the outer surface of the filter plate. At the same time, the scraper drives the push rod to move. When the push rod moves, it abuts against the arc-shaped surface, thereby moving the contact plate. Then, the contact plate drives the positioning plate to slide in the positioning groove. During the movement, the positioning plate... The first spring is stretched, which also drives the vibrating block to move away from the filter plate. When the vibrating block moves to a suitable height, the push rod will separate from the arc surface under the action of rotation. At this time, the first spring resets and the gravity of the positioning plate pushes the vibrating block to move towards the filter plate. The vibrating block knocks and vibrates the filter plate, making it easier for impurities that have not completely detached from the filter plate to fall off. At the same time, it accelerates the separation speed of impurities from the surface of the filter plate, improves the cleaning efficiency, keeps the filter plate in a good air permeability and adsorption performance, ensures efficient adsorption of pollutants in the exhaust gas, and maintains the effectiveness of the entire treatment equipment in purifying toxic substances.

[0007] The present invention is further configured such that: the drive structure includes a motor fixedly connected to the processing box, the output end of the motor is provided with a rotating shaft, one end of the rotating shaft extends into the interior of the cavity structure and is fixedly provided with a connecting block, the connecting block is provided with a slot, the scraper is fixedly provided with an installation block on the side away from the brush, the installation block is fixedly provided with a locking block, and the locking block and the locking slot are inserted into each other.

[0008] The present invention is further configured such that: a limiting groove is provided on the card block, a sliding groove communicating with the limiting groove is provided on the connecting block, a guide groove is provided on the inner wall of the sliding groove, a limiting block is slidably arranged inside the sliding groove, the limiting block can be inserted into the limiting groove, a guide block is fixedly arranged on the limiting block, the guide block and the guide groove are slidably connected, and a second spring is fixedly arranged between the side of the guide block in the sliding direction and the inner wall of the guide groove.

[0009] By adopting the above technical solution, the starting motor drives the rotating shaft to rotate, which in turn drives the connecting block to rotate. The connecting block then drives the mounting block to rotate, and finally, the mounting block drives the scraper to rotate. By moving the limiting block within the guide groove, the limiting block causes the guide block to slide within the guide groove. As the guide block moves, it compresses the second spring. By moving the limiting block away from the limiting groove, the limiting of the locking block and the locking groove is released, allowing the connecting block and the mounting block to separate.

[0010] The present invention is further configured such that: a sliding channel communicating with the cavity structure is provided on the processing box, a collection box is slidably arranged inside the sliding channel, and a guide plate is fixedly arranged between the collection box and the filter plate.

[0011] By adopting the above technical solution, the collection box collects the cleaned-up impurities. By pulling the collection box, it can be moved to the outside of the processing box for centralized processing of the impurities.

[0012] The present invention is further configured such that: a maintenance channel communicating with the cavity structure is provided on the processing box, and a baffle is provided at the opening of the maintenance channel, and the baffle and the processing box are detachably fixedly connected.

[0013] The present invention is further characterized by having a handle fixedly mounted on the baffle.

[0014] By adopting the above technical solution, the detachable connection facilitates the installation and removal of the baffle; by pulling the handle, the baffle is detached from the treatment box, and then the maintenance channel facilitates the replacement and maintenance of the filter plate and scraper by the staff.

[0015] The beneficial effects of this invention are as follows: When the device is working, the inlet pipe is first connected to the external exhaust pipe. The exhaust gas enters the cavity structure through the inlet pipe and comes into contact with the filter plate, allowing the filter plate to adsorb and filter the exhaust gas, effectively reducing harmful substances in the exhaust gas emissions and lowering the degree of air pollution. When the filter plate needs to be cleaned later, the drive structure is activated to rotate the scraper. The scraper then drives the brush to clean the outer surface of the filter plate. At the same time, the scraper drives the push rod to move. When the push rod moves, it abuts against the arc-shaped surface, thereby moving the contact plate. Then, the contact plate drives the positioning plate to slide in the positioning groove. The positioning plate moves... During the process, the first spring is stretched, which also drives the vibrating block to move away from the filter plate. When the vibrating block moves to a suitable height, the push rod will separate from the arc surface under the action of rotation. At this time, the first spring resets and the gravity of the positioning plate pushes the vibrating block to move towards the filter plate. The vibrating block knocks and vibrates the filter plate, making it easier for impurities that have not completely detached from the filter plate to fall off. At the same time, it accelerates the separation speed of impurities from the surface of the filter plate, improves the cleaning efficiency, keeps the filter plate in a good air permeability and adsorption performance, ensures efficient adsorption of pollutants in the exhaust gas, and maintains the effectiveness of the entire treatment equipment in purifying toxic substances.

[0022] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0023] like Figures 1 to 3 As shown, a ship exhaust gas treatment device includes a treatment box 1, which is a cavity structure 2. An air inlet pipe 3 connected to the cavity structure 2 is fixedly installed on the treatment box 1. The air inlet pipe 3 is connected to an external exhaust gas treatment pipe, or the exhaust gas can be cooled by an external cooling module and then transported to the interior of the treatment box 1 through the air inlet pipe 3. An air outlet pipe 4 connected to the cavity structure 2 is fixedly installed on the treatment box 1. A filter plate 5 is installed inside the cavity structure 2. An installation groove is opened in the inner wall of the cavity structure 2. The side of the filter plate 5 extends into the installation groove. A scraper 9 is installed on one side of the filter plate 5. A brush 10 is fixedly installed on the scraper 9. The brush 10 abuts against the filter plate 5, and the movement of the brush 10 scrapes and cleans the filter plate 5.

[0024] like Figure 3As shown, a push rod 1017 is fixedly installed on the side of the scraper 9 away from the brush 10. There are two push rods 1017. A positioning groove 1011 is vertically opened on the processing box 1. A positioning plate 1012 is slidably installed inside the positioning groove 1011. The positioning plate 1012 slides along the opening direction of the positioning groove 1011. A vibration block 1014 is fixedly installed at one end of the positioning plate 1012. One end of the vibration block 1014 extends to the outside of the positioning groove 1011 and can abut against the filter plate 5. A contact plate 1015 is fixedly installed at the end of the positioning plate 1012 away from the vibration block 1014. The end of the contact plate 1015 facing the push rod 1017 is an arc-shaped surface 1016. The push rod 1017 abuts against the arc-shaped surface 1016. A first spring 1013 is fixedly installed between the positioning plate 1012 and the positioning groove 1011 near the inner wall of the filter plate 5. When the push rod 1017 abuts against the arc-shaped surface 1016, the contact plate 1015 is pushed by the push rod 1017. As the push rod 1017 continues to move, the contact plate 1015 moves away from the push rod 1017. At this time, the first spring 1013 deforms from the compressed state to the stretched state under the force. The contact plate 1015 pulls up the vibrating block 1014 through the positioning plate 1012, so that the vibrating block 1014 is separated from the filter plate 5. When the push rod 1017 separates from the arc-shaped surface 1016, the first spring 1013 deforms from the stretched state to the compressed state, so that the positioning plate 1012 drives the vibrating block 1014 to move and the vibrating block 1014 impacts the filter plate 5 to generate vibration, so that foreign objects on the surface of the filter plate 5 are dislodged by vibration. The processing box 1 is provided with a drive structure that can drive the scraper 9 to move.

[0025] like Figure 2 As shown, the drive structure includes a motor 6 fixedly connected to the outside of the processing box 1. The output end of the motor 6 is equipped with a rotating shaft 7. One end of the rotating shaft 7 extends into the interior of the cavity structure 2 and is fixedly equipped with a connecting block 1032. A mounting block 8 is fixedly installed on the side of the scraper 9 away from the brush 10. A locking block 1031 is fixedly installed on the side of the mounting block 8 away from the brush 10. A locking groove 1033 is opened on the connecting block 1032 along the axial direction of the rotating shaft 7. The locking block 1031 and the locking groove 1033 are inserted into each other.

[0026] like Figure 4As shown, a limiting groove 1046 is formed through the card block 1031. A sliding groove 1041 communicating with the limiting groove 1046 is formed radially along the rotating shaft 7 on the connecting block 1032. A guide groove 1042 is formed on the inner wall of the sliding groove 1041. A limiting block 1043 is slidably disposed inside the sliding groove 1041. The limiting block 1043 can be inserted into the limiting groove 1046. The limiting block 1043 reciprocates along the opening direction of the sliding groove 1041. A guide block 1044 is fixedly disposed on the limiting block 1043. 1044 and guide groove 1042 are slidably connected. A second spring 1045 is fixedly installed between the side of guide block 1044 in the sliding direction and the inner wall of guide groove 1042. When the second spring 1045 is in a non-stressed state, the limiting block 1043 and limiting groove 1046 are inserted to limit the connecting block 1032 and mounting block 8. When the second spring 1045 is in a compressed state, the limiting block 1043 and limiting groove 1046 are separated, and the connecting block 1032 and mounting block 8 can be separated.

[0027] like Figure 2 As shown, the processing box 1 has a sliding channel 1021 that communicates with the cavity structure 2. A collection box 1022 is slidably disposed inside the sliding channel 1021. The collection box 1022 can be moved to the outside of the processing box 1. The collection box 1022 is located below the filter plate 5. The opening of the collection box 1022 faces the filter plate 5. A guide plate 1023 is fixedly disposed between the collection box 1022 and the filter plate 5. The guide plate 1023 can guide foreign objects falling from the filter plate 5 into the opening of the collection box 1022.

[0028] like Figure 5 As shown, the processing box 1 has a maintenance channel 1051 communicating with the cavity structure 2. The maintenance channel 1051 is a one-way opening, and a baffle 1052 is provided at the opening of the maintenance channel 1051 to close the maintenance channel 1051. The baffle 1052 and the processing box 1 are detachably fixedly connected. The detachable connection includes, but is not limited to, a threaded connection; the processing box 1 has threaded holes through bolts threaded on the baffle 1052, and the connection is made through the bolts and threaded holes. A handle 1061 is fixedly provided on the baffle 1052.

[0029] First, the intake pipe 3 is connected to the external exhaust pipe. The exhaust gas enters the cavity structure 2 through the intake pipe 3 and comes into contact with the filter plate 5, allowing the filter plate 5 to adsorb and filter the exhaust gas, effectively reducing harmful substances in the exhaust gas emissions and lowering the degree of air pollution. When the filter plate 5 needs to be cleaned later, the drive structure is activated to rotate the scraper 9. Then, the scraper 9 drives the brush 10 to clean the outer surface of the filter plate 5. At the same time, the scraper 9 drives the push rod 1017 to move. When the push rod 1017 moves, it will abut against the arc surface 1016, thereby driving the contact plate 1015 to move. Then, the contact plate 1015 drives the positioning plate 1012 to slide in the positioning groove 1011. During the movement, the positioning plate 1012 pushes against the first spring 1. 013 is stretched, which also drives the vibrating block 1014 to move away from the filter plate 5. When the vibrating block 1014 moves to a suitable height, the push rod 1017 will separate from the arc surface 1016 under the action of rotation. At this time, the first spring 1013 resets and the gravity of the positioning plate 1012 pushes the vibrating block 1014 to move towards the filter plate 5. The vibrating block 1014 knocks and vibrates the filter plate 5, so that the impurities that have not completely detached inside the filter plate 5 can fall off more easily. At the same time, it accelerates the speed at which impurities are separated from the surface of the filter plate 5, improves the cleaning efficiency, and keeps the filter plate 5 in a good air permeability and adsorption performance, ensuring the efficient adsorption of pollutants in the exhaust gas and maintaining the effectiveness of the entire treatment equipment in purifying toxic substances.

[0030] The motor 6 is started to drive the rotating shaft 7 to rotate, then the rotating shaft 7 drives the connecting block 1032 to rotate, then the connecting block 1032 drives the mounting block 8 to rotate, and then the mounting block 8 drives the scraper 9 to rotate.

[0031] The movable limiting block 1043 slides in the guide groove 1042. During the movement, the limiting block 1043 drives the guide block 1044 to slide in the guide groove 1042. When the guide block 1044 moves, it compresses the second spring 1045. By moving the limiting block 1043 away from the limiting groove 1046, the limiting of the locking block 1031 and the locking groove 1033 can be canceled. At this time, the connecting block 1032 and the mounting block 8 can be separated.

[0032] The collection box 1022 collects the cleaned-up impurities. By pulling the collection box 1022, it can be moved to the outside of the processing box 1 for centralized processing of the impurities.

[0033] The detachable connection makes it easy to install and remove the baffle 1052; by pulling the handle 1061, the baffle 1052 can be detached from the treatment box 1, and then the maintenance channel 1051 makes it convenient for staff to replace and maintain the filter plate 5 and scraper 9.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model.
