Description

Technical Field

[0001] The invention relates to the technical field of sedimentation tanks, in particular to a sedimentation tank for EGR water treatment. Background Art

[0002] iCER (intelligent control of exhaust gas recirculation) is called a low-pressure exhaust gas recirculation system, a type of EGR, which is used to remove and separate emulsified oil / solids / carbon and water. It is suitable for liquids of similar density that cannot be separated by centrifugation and sedimentation. These liquids are usually separated by sedimentation in an inclined plate sedimentation tank during the treatment process.

[0003] However, during the use of traditional inclined plate sedimentation tanks, water flows from top to bottom into the bottom of the inclined plate, and the particulate matter in the sewage will slide along the inclined plate into the sludge storage hopper at the bottom. At the same time, the sludge particles with high density will gradually settle on the bottom surface of the inclined plate. The accumulation of these particles on the inclined plate will affect the subsequent sedimentation effect and efficiency. After the inclined plate sedimentation tank has been used for a period of time, sludge will float up in the inclined plate sedimentation tank. When discharged, the floating sludge will be discharged through the drain pipe together with the clean water, resulting in more sludge in the clean water after sedimentation. At the same time, when installing the inclined plate, multiple bolts are usually used to install it on the inclined plate sedimentation tank, and the installation and fixing with multiple bolts leads to low efficiency.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figure 1-Figure 12As shown, the sedimentation tank for EGR water treatment described in the present invention comprises an inclined plate sedimentation tank body 1; an inlet pipe 8, the inclined plate sedimentation tank body 1 is equipped with an inlet pipe 8; a drain pipe 7, the inclined plate sedimentation tank body 1 is equipped with a drain pipe 7; a fixed plate 9, the inclined plate sedimentation tank body 1 is slidably connected with the fixed plate 9; an inclined plate 10, the fixed plate 9 is equipped with an inclined plate 10, and the inclined plate 10 is detachably connected to the inclined plate sedimentation tank body 1; a scraping structure 2, the inclined plate sedimentation tank body 1 is provided with a scraping structure 2, the scraping The structure 2 includes a first hydraulic rod 201, which is provided on the inclined plate sedimentation tank body 1, and a mounting plate 202 is installed on the telescopic end of the first hydraulic rod 201, and a plurality of fixed rods 203 are fixedly connected to the mounting plate 202, and two scrapers 204 are slidably connected to the plurality of fixed rods 203, and a connecting column 205 is rotatably connected to the scrapers 204; a mounting structure 5, which is provided on the inclined plate sedimentation tank body 1; a filtering structure 6, which is provided on the inclined plate sedimentation tank body 1.

[0038] Specifically, the fixed rod 203 is provided with a driving structure 4 for driving the scraper 204 to extend and retract, and the driving structure 4 includes a driving plate 402, and the fixed rod 203 is slidably connected with the driving plate 402, and the connecting column 205 is rollingly matched with the driving groove 401 on the driving plate 402, and the two driving grooves 401 are inclined. Both ends of the scraper 204 are fixedly connected with scraper rods 206, and the two scraper rods 206 at both ends of the scraper 204 are respectively slidably connected with the inclined plate sedimentation tank body 1 and the fixed plate 9, and the scraper rods 206 on the two scrapers 204 symmetrically arranged on the left and right are staggered. The driving plate 402 is fixedly connected with a second sliding rod 403, and the second sliding rod 403 is slidably connected to the fixed rod 203. The second sliding rod 403 is slidably connected to the mounting plate 202, and the second sliding rod 403 is slidably fixedly connected to the mounting rod 404. A third hydraulic rod 405 is fixedly connected to one of the fixing rods 203, and the telescopic end of the third hydraulic rod 405 is fixedly connected to the mounting rod 404. First, the sewage enters the inclined plate sedimentation tank body 1 from the water inlet pipe 8. Since the lengths of the two middle inclined plates 10 on the fixing plate 9 are longer, an intermediate waterway is formed, and the sewage flows into the intermediate waterway. After the sewage enters the sedimentation tank, the water flows from top to bottom into the bottom of the inclined plate 10, and the particulate matter in the sewage slides along the inclined plate 10 into the sludge storage hopper at the bottom. At the same time, the sludge particles with large density will gradually settle on the inclined plate 10. When the inclined plate 10 needs to be adjusted, When the sludge particles on the plate 10 are scraped off, the third hydraulic rod 405 can be started. When the telescopic end of the third hydraulic rod 405 is extended, the mounting rod 404 is driven to move upward. When the mounting rod 404 moves upward, multiple second slide bars 403 are driven to slide upward. The second slide bars 403 will drive the driving plate 402 to slide upward on the fixed rod 203. When the driving plate 402 slides, the connecting column 205 rolls in the driving groove 401. Since the two driving grooves 401 are inclined, the two connecting columns 205 drive the two scrapers 204 to slide between the fixed rod 203, so that the two scrapers 204 on the multiple fixed rods 203 slide toward each other. At this time, the first hydraulic rod 201 is started. When the telescopic end of the first hydraulic rod 201 is extended, the mounting rod 404 is driven to slide upward. The second slide bars 403 will drive the driving plate 402 to slide upward on the fixed rod 203. When the driving plate 402 slides, the connecting column 205 rolls in the driving groove 401. Since the two driving grooves 401 are inclined, the two connecting columns 205 drive the two scrapers 204 to slide between the fixed rod 203, so that the two scrapers 204 on the multiple fixed rods 203 slide toward each other. The plate 202 moves upward, and the mounting plate 202 drives the fixing rod 203 to move upward, so that the fixing rod 203 drives the scraper 204 to move to the top of the inclined plate 10, and then the third hydraulic rod 405 is retracted to make the scraper 204 return to the initial position, and then the first hydraulic rod 201 is retracted to make the fixing rod 203 drive the scraper 204 to scrape the sludge impurities on the inclined plate 10, and at the same time, the scraper 204 drives the scraper rod 206 to scrape the sludge impurities on the fixing plate 9 and the inclined plate sedimentation tank body 1, so that the sludge impurities on the inclined plate 10 are scraped by the scraper 204, avoiding the accumulation of a large amount of impurities on the inclined plate 10 to affect the later sedimentation effect and efficiency, and the scraper 204 slides towards the fixing rod 203 when moving upward,This prevents the scraper 204 from scraping the sludge above the inclined plate 10 when it moves upward.

[0039] Specifically, the inclined plate sedimentation tank body 1 is provided with a sealing structure 3, and the sealing structure 3 includes a sealing plate 301. Two sealing plates 301 are slidably connected to the inclined plate sedimentation tank body 1, and a first sliding rod 302 is fixedly connected between the two sealing plates 301. A guide rod 303 is fixedly connected to the inclined plate sedimentation tank body 1, and the first sliding rod 302 is slidably connected to the guide rod 303. A connecting rod 304 is fixedly connected to the sealing plate 301 on the left side, and a second hydraulic rod 305 is installed on the inclined plate sedimentation tank body 1, and the telescopic end of the second hydraulic rod 305 is fixedly connected to the connecting rod 304. The filtering structure 6 includes a mounting frame 601, and the inclined plate sedimentation tank body 1 is provided with a second hydraulic rod 305, and the telescopic end of the second hydraulic rod 305 is fixedly connected to the connecting rod 304. The plate sedimentation tank body 1 is detachably connected with a mounting frame 601, and a filter screen 602 is fixedly connected to the mounting frame 601. A clamping block 603 is slidably connected to the inclined plate sedimentation tank body 1, and the clamping block 603 is engaged with a clamping groove 604 on the mounting frame 601. A pull column 606 is fixedly connected to the clamping block 603, and the pull column 606 is fixedly connected to the inclined plate sedimentation tank body 1. A reset spring 605 is fixedly connected between the clamping block 603 and the inclined plate sedimentation tank body 1. When the sewage is precipitated, the clean water can be discharged through the drain pipe 7. When the water is discharged from the drain pipe 7, the impurities floating in the water will be filtered through the filter screen 602 on the mounting frame 601. When the filter screen 602 needs to be cleaned, the clean water can be discharged through the drain pipe 7. When the water is discharged from the drain pipe 7, the impurities floating in the water will be filtered through the filter screen 602 on the mounting frame 601. When the impurities on the net 602 are cleaned, the second hydraulic rod 305 can be started. When the telescopic end of the second hydraulic rod 305 contracts, it drives the connecting rod 304 to move downward. When the connecting rod 304 moves downward, it drives the sealing plate 301 on the left to slide downward. When the sealing plate 301 on the left slides downward, it drives the sealing plate 301 on the right to slide downward through the first slide bar 302. When the first slide bar 302 slides downward, it slides more smoothly through the guide rod 303. At this time, the two sealing plates 301 seal the two water outlets. At this time, the pull column 606 can be pulled downward. When the pull column 606 moves downward, it drives the block 603 to slide downward. When the block 603 slides downward, the reset spring 605 contracts, and the block 603 slides downward. The block 603 is no longer engaged with the card slot 604 on the installation frame 601, and then the installation frame 601 can be pulled outward, so that the installation frame 601 drives the filter screen 602 to slide out of the inclined plate sedimentation tank body 1. At this time, the impurities on the filter screen 602 can be cleaned, so as to prevent the impurities floating in the clean water from being discharged through the drain pipe 7 with the clean water through the filter screen 602, thereby improving practicality. The engagement between the card block 603 and the installation frame 601 facilitates the rapid disassembly and installation between the installation frame 601 and the inclined plate sedimentation tank body 1, thereby improving the installation and disassembly efficiency. The two water outlets are sealed by the sealing plate 301, thereby preventing the clean water from flowing out of the two water outlets when the filter screen 602 is disassembled.

[0040] Specifically, the mounting structure 5 includes a mounting column 501, the mounting column 501 is slidably connected to the inclined plate sedimentation tank body 1, the mounting column 501 is engaged with the mounting grooves 502 on the inclined plates 10 on both sides of the fixed plate 9, the mounting column 501 is fixedly connected to the slide plate 503, the slide plate 503 is slidably connected to the inclined plate sedimentation tank body 1, a screw rod 504 is rotatably connected to the inclined plate sedimentation tank body 1, the screw rod 504 is threadedly connected to the slide plate 503, a hand wheel 505 is fixedly connected to the screw rod 504, and the threads at both ends of the screw rod 504 are in opposite directions. When the inclined plate 10 needs to be replaced, it can be replaced by rotating the hand wheel 5 05. When the hand wheel 505 rotates, it drives the screw rod 504 to rotate. Since the threads at both ends of the screw rod 504 are in opposite directions, the two slide plates 503 can be driven to move back and forth. When the slide plate 503 slides, it drives the installation column 501 to move, so that the installation column 501 is no longer engaged with the installation groove 502 on the inclined plate 10, so that the two slide plates 503 are driven to slide back and forth through the screw rod 504 thread, so that the two slide plates 503 simultaneously drive the installation column 501 to no longer be engaged with the installation groove 502 on the inclined plate 10, so that the inclined plate 10 and the inclined plate sedimentation tank body 1 can be quickly fixed and installed, thereby improving the installation efficiency between the inclined plate 10 and the inclined plate sedimentation tank body 1.

[0041] When the present invention is in use, first, sewage enters the inclined plate sedimentation tank body 1 from the water inlet pipe 8. Since the length of the two middle inclined plates 10 on the fixed plate 9 is relatively long, an intermediate waterway is formed, and the sewage flows into the intermediate waterway. After the sewage enters the sedimentation tank, the water flows from top to bottom into the bottom of the inclined plate 10, and the particulate matter in the sewage slides along the inclined plate 10 into the sludge storage hopper at the bottom. At the same time, the sludge particles with high density will gradually settle on the inclined plate 10. When it is necessary to scrape the sludge particles of the inclined plate 10, the third hydraulic rod 405 can be started, and the third hydraulic rod 405 can be started. When the telescopic end of the pressure rod 405 is extended, it drives the installation rod 404 to move upward. When the installation rod 404 moves upward, it drives multiple second slide bars 403 to slide upward. The second slide bars 403 drive the driving plate 402 to slide upward on the fixed rod 203. When the driving plate 402 slides, the connecting column 205 rolls in the driving groove 401. Since the two driving grooves 401 are inclined, the two connecting columns 205 drive the two scrapers 204 to slide between the fixed rod 203, so that the two scrapers 204 on the multiple fixed rods 203 slide toward each other. By starting the first hydraulic rod 201, the telescopic end of the first hydraulic rod 201 extends and drives the mounting plate 202 to move upward, and the mounting plate 202 drives the fixing rod 203 to move upward, so that the fixing rod 203 drives the scraper 204 to move to the top of the inclined plate 10, and then the third hydraulic rod 405 is retracted to make the scraper 204 return to the initial position, and then the first hydraulic rod 201 is retracted to make the fixing rod 203 drive the scraper 204 to scrape the sludge impurities on the inclined plate 10, and at the same time, the scraper 204 drives the scraper rod 206 to scrape the fixed plate 9 and the inclined plate sedimentation The sludge impurities on the pool body 1 are scraped off, and the scraping rods 206 on the two scrapers 204 symmetrically arranged on the left and right are staggered, so that when the two scrapers 204 move relatively, the scraping rods 206 on the scrapers 204 will not block each other, so that the sludge impurities on the inclined plate 10 are scraped off by the scrapers 204, avoiding the accumulation of a large amount of impurities on the inclined plate 10 to affect the later sedimentation effect and efficiency, and the scrapers 204 slide towards the fixed rods 203 when moving upward, avoiding the scrapers 204 from scraping the sludge above the inclined plate 10 when moving upward;

[0042] When the sewage is precipitated, the clean water can be discharged through the drain pipe 7. When the water is discharged from the drain pipe 7, the impurities floating in the water will be filtered through the filter screen 602 on the installation frame 601. When the impurities on the filter screen 602 need to be cleaned, the second hydraulic rod 305 can be started. When the telescopic end of the second hydraulic rod 305 contracts, the connecting rod 304 is driven to move downward. When the connecting rod 304 moves downward, the sealing plate 301 on the left side is driven to slide downward. When the sealing plate 301 on the left side slides downward, the sealing plate 301 on the right side is driven to slide downward through the first slide bar 302. When the first slide bar 302 slides downward, it slides more smoothly through the guide rod 303. At this time, the two sealing plates 301 seal the two water outlets. At this time, the pull column 606 can be pulled downward. When the pull column 606 moves downward, it drives The movable block 603 slides downward, and the return spring 605 contracts when the block 603 slides downward. At the same time, the block 603 is no longer engaged with the slot 604 on the installation frame 601. Then the installation frame 601 can be pulled outward, so that the installation frame 601 drives the filter screen 602 to slide out of the inclined plate sedimentation tank body 1. At this time, the impurities on the filter screen 602 can be cleaned, so that the impurities floating in the clean water are prevented from being discharged through the drain pipe 7 with the clean water through the filter screen 602, thereby improving practicality. The engagement between the block 603 and the installation frame 601 facilitates the quick disassembly and installation between the installation frame 601 and the inclined plate sedimentation tank body 1, thereby improving the installation and disassembly efficiency. The two water outlets are sealed by the sealing plate 301, thereby preventing the clean water from flowing out of the two water outlets when the filter screen 602 is disassembled.

[0043] When the inclined plate 10 needs to be replaced, the hand wheel 505 can be rotated, and the rotation of the hand wheel 505 drives the screw rod 504 to rotate. Since the threads at both ends of the screw rod 504 are in opposite directions, the two slide plates 503 can be driven to move back and forth. When the slide plate 503 slides, it will drive the installation column 501 to move, so that the installation column 501 no longer engages with the installation groove 502 on the inclined plate 10, so that the two slide plates 503 are driven to slide back and forth through the screw rod 504 thread, so that the two slide plates 503 simultaneously drive the installation column 501 no longer engage with the installation groove 502 on the inclined plate 10, so that the inclined plate 10 and the inclined plate sedimentation tank body 1 can be quickly fixed and installed, thereby improving the installation efficiency between the inclined plate 10 and the inclined plate sedimentation tank body 1.
