[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] In the embodiment, Figure 1-4 A smoke pipe cleaning device for a smoke sampler is provided. The utility model comprises a smoke sampler body 1, a smoke pipe 2 is installed on the outer side of the smoke sampler body 1, an air pipe 3 connected to the smoke sampler body 1 is arranged inside the smoke pipe 2, an air valve 4 is arranged on the outer side of the air pipe 3, a partition plate 5 is arranged inside the smoke pipe 2, a fan 6 is arranged on the top of the partition plate 5, a transmission device 7 is arranged inside the smoke pipe 2, a cleaning disc 8 is fixedly connected to the outer side of the transmission device 7, a first make way groove is opened inside the smoke pipe 2, a second make way groove located below the first make way groove is opened inside the smoke pipe 2, and a shielding device 9 corresponding to the first make way groove is arranged inside the second make way groove.
[0028] Among them, the transmission device 7 includes a motor 71 fixedly connected to the inside of the smoke pipe 2, the outer side of the output shaft of the motor 71 is fixedly connected to a threaded rod 72 rotatably connected to the inside of the smoke pipe 2, the outer side of the threaded rod 72 is connected to a transmission block 73 fixedly connected to the inside of the cleaning disk 8 through a threaded transmission, and the inside of the smoke pipe 2 is fixedly connected to a limit rod 74 slidably connected to the transmission block 73.
[0029] The start of the motor 71 drives the threaded rod 72 to rotate, so that the transmission block 73 drives the cleaning plate 8 to move up and down through the thread, and the limit rod 74 prevents the transmission block 73 from rotating.
[0030] Among them, the cleaning disk 8 includes a plurality of connecting rods 81 fixedly connected to the outer side of the transmission device 7, and the opposite sides of the plurality of connecting rods 81 are fixedly connected to the mounting disk 82. A first scraper 83 is fixedly connected to the outer side of the mounting disk 82, and a third clearance groove is opened inside the first scraper 83, and a cleaning brush 84 is arranged inside the third clearance groove.
[0031] The connecting rod 81 moves along with the movement of the transmission block 73 , and when moving, the first scraper 83 and the cleaning brush 84 on the outside clean the inner wall of the smoke pipe 2 .
[0032] The second scrapers 10 are disposed on both upper and lower sides of the first scraper 83 , and the cleaning brush 84 is located between the two second scrapers 10 .
[0033] The cleaning brush 84 slightly exceeds the extension length of the second scraper 10 . When the second scraper 10 cleans the inner wall of the smoke tube 2 , the cleaning brush 84 will sweep away the scraped debris.
[0034] The shielding device 9 includes a bolt 91 connected to the internal thread of the second clearance groove, a knob 92 is provided on the outer side of the bolt 91, and a baffle 93 is fixedly connected to the outer side of the bolt 91.
[0035] By turning the bolt 91 through the knob 92 , the baffle 93 fixed to the bolt 91 will rotate accordingly, so that the baffle 93 covers or opens the first clearance slot.
[0036] The area of the baffle 93 is larger than the area of the first clearance groove, and a sealing gasket 11 is arranged inside the second clearance groove.
[0037] When the baffle 93 blocks the first clearance groove, the sealing gasket 11 increases the degree of sealing to prevent the gas from escaping from the bottom. When the baffle 93 is rotated at a certain angle, the first clearance groove can be connected with the second clearance groove.
[0038] Working principle:
[0039] When it is necessary to clean the inner wall of the smoke pipe 2, the air valve 4 can be closed first to block the connection between the smoke pipe 2 and the smoke sampler body 1, and then the motor 71 can be started. The cleaning disk 8 will move up and down under the drive of the motor 71, and the second scraper 10 and the cleaning brush 84 will clean the inner wall of the smoke pipe 2. At this time, the knob 92 can be turned at the same time to remove the baffle 93, and the fan 6 can be started to blow the wind downward. The wind will enter from the pipe mouth of the smoke pipe 2 and be discharged from the second make way slot, and will assist the cleaning disk 8 in cleaning the pipe wall. After cleaning, the baffle 93 is fixed by the bolt 91, the first make way slot is covered, and the air valve 4 is opened. At this time, the gas entering from the pipe mouth can enter the smoke sampler body 1 normally through the air pipe 3 for detection.
