AI Technical Summary
When cleaning the filter, the existing flue gas automatic blowing mechanism is a distance from the filter, which leads to insufficient cleaning and the dust particles adhered to the surface of the filter cannot be completely blown away, resulting in clogging of the filter.
An automatic flue gas backfurrowing mechanism is designed, including a box, a backfurrowing device and a driving device. The back-blowing device consists of a shell, a blowing duct, a winding rope and a winding roller. The winding rope is retracted and the winding duct is driven upward to achieve a detailed back-blowing of the filter plate.

[0030] A back blowing device, which is arranged inside the box body 1;
[0031] A driving device is arranged on the top of the box body 1;
[0032] Among them, the backwashing device includes a round rod 3. Both the top and the bottom of the round rod 3 are fixedly connected to the inner surface of the box body 1. A slider 4 is movably sleeved on the bottom of the outer surface of the round rod 3. A shell 5 is fixedly connected between the sliders 4. A blowing air pipe 6 is fixedly connected to the back of the shell 5. A fixed pipe 25 is fixedly connected to the back of the blowing air pipe 6. A spring 8 is fixedly connected to the bottom of the shell 5. The bottom end of the spring 8 is fixedly connected to the inner wall of the box body 1. A winding rope 7 is fixedly connected to the top of the shell 5. The top end of the winding rope 7 penetrates through the box body 1 and extends above the box body 1. When the winding rope 7 is wound up, the shell 5 will be driven to rise.
[0033] By setting the winding rope 7, when the operator finishes sampling the flue gas and needs to clean the filter plate 2, the winding rope 7 can be wound up, so that the shell 5 rises. As a result, the gas blown out through the fixed pipe 25 and the blowing air pipe 6 can carefully clean the filter plate 2. When the shell 5 rises, it will drive the slider 4 to rise along the outer surface of the round rod 3, so that the shell 5 can rise more stably. By setting the spring 8, after the spring 8 is stretched, it can drive the shell 5 to move downward under the action of elastic force recovery, so that the shell 5 can reset.
[0034] Among them, the driving device includes:
[0035] A fixed plate 9, the bottom of the fixed plate 9 is fixedly connected to the top of the box body 1;
[0036] A first motor 10, the left side of the first motor 10 is fixedly connected to the outer surface of the fixed plate 9. The other end of the output shaft of the first motor 10 is fixedly connected to a winding roller 11. The other end of the winding roller 11 penetrates through the fixed plate 9 and extends into the fixed plate 9 and is movably sleeved with the inner wall of the fixed plate 9. The outer surface of the winding roller 11 is fixedly connected to the top end of the winding rope 7.
[0037] The operator starts the first motor 10, so that the winding roller 11 can rotate, and thus the winding roller 11 can wind up the winding rope 7.
[0038] Among them, a flue gas port 12 is opened on the back of the box body 1, and a valve 13 located on the back of the flue gas port 12 is fixedly installed on the back of the box body 1.
[0039] The operator can open the valve 13, so that the flue gas can pass through the flue gas port 12, thereby collecting and sampling the flue gas.
[0040] Among them, a blower 14 is fixedly installed at the rear side of the top of the box body 1. An air inlet pipe 15 is fixedly installed at the top of the blower 14. The bottom of the blower 14 is fixedly connected with a connecting hose 16. The bottom end of the connecting hose 16 penetrates through the box body 1 and extends into the interior of the box body 1 and is fixedly connected to the back surface of the fixed pipe 25.
[0041] The operator starts the blower 14, so that the air inlet pipe 15 can suck in air, and then enters the interior of the fixed pipe 25 through the connecting hose 16.
[0042] Among them, sliding grooves 17 are formed on both sides inside the box body 1 and are located in front of the filter plate 2. A scraper 18 is movably sleeved inside the sliding grooves 17.
[0043] By setting the scraper 18, the scraper 18 can scrape out the dust particles that have not been blown away inside the box body 1 to the outside of the box body 1.
[0044] Among them, a mounting plate 19 is fixedly installed at the bottom of the box body 1. A second motor 20 is fixedly connected to the right side of the mounting plate 19. The other end of the output shaft of the second motor 20 is fixedly connected with a threaded rod 21. A moving block 22 is threadedly sleeved on the outer surface of the threaded rod 21.
[0045] The operator starts the second motor 20, so that the threaded rod 21 can rotate, and further the threaded rod 21 can drive the moving block 22 to move.
[0046] Among them, a hinge rod 23 is hinged inside the front end of the moving block 22. A connecting rod 24 is movably sleeved inside the other end of the hinge rod 23. The movement of the hinge rod 23 will drive the movement of the connecting rod 24. The top end of the connecting rod 24 penetrates through the box body 1 and extends into the interior of the box body 1 and is movably sleeved with the inner wall of the box body 1. The top end of the connecting rod 24 is fixedly connected to the bottom of the scraper 18.
[0047] When the moving block 22 moves, it will cause the hinge rod 23 to drive the connecting rod 24 to move, and further the connecting rod 24 can drive the scraper 18 to move.
[0048] The working principle and usage process of the present utility model:
[0049] The operator can open valve 13 so that the flue gas can pass through the flue gas port 12, thereby collecting and sampling the flue gas. After the operator completes the flue gas collection, the operator can start the fan 14 so that the air inlet pipe 15 can suck in air, and then through the connecting hose 16 and the fixed pipe 25, and finally blown out by the blowing pipe 6, thereby performing a backwashing treatment on the filter plate 2. At this time, the operator starts the first motor 10 so that the winding roller 11 can rotate, thereby winding the winding rope 7, so that the winding rope 7 can drive the housing 5 and the blowing pipe 6 to move upward, so that the blowing pipe 6 can perform a more detailed and comprehensive backwashing treatment on the filter plate 2, thereby cleaning the dust on the surface and inside of the filter plate 2 more cleanly.
[0050] After the operator finishes the backwashing of the filter plate 2, the operator can start the second motor 20 so that the threaded rod 21 can drive the moving block 22 to move, so that the hinge rod 23 can push the connecting rod 24 to move outward, and then the connecting rod 24 can drive the scraping plate 18 to move outward, so that the scraping plate 18 can scrape the dust particles that have not been blown away inside the box body 1 to the outside of the box body 1, so that the inner surface of the box body 1 can be kept clean.
