DETAILED DESCRIPTION
[0019] 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.
[0020] Example 1
[0021] like Figure 1-4 As shown in the figure, a smoke exhaust pipe with an anti-blocking structure includes a bottom pipe 1 and an anti-blocking component installed above the bottom pipe 1, the anti-blocking component includes a mounting pipe 2, a middle pipe 7, and a top pipe 14, the bottom pipe 1 is fixedly mounted with mounting pipes 2 on both upper and lower sides, the mounting pipe 2 is provided with mounting screw holes 3 inside, the inner wall of the bottom pipe 1 is fixedly mounted with a limit plate 4, the top of the limit plate 4 is mounted with a sieve plate 5, the outside of the bottom pipe 1 is meshed with a fixed outer frame 6, and the side of the fixed outer frame 6 is fixedly mounted with a mounting side plate 17 A middle pipe 7 is installed on the top of the bottom pipe 1, a top pipe 14 is fixedly installed on the top of the middle pipe 7, a mounting rear plate 15 is installed behind the top pipe 14, a rear screw hole 16 is opened inside the mounting rear plate 15, a first rotating shaft 8 is fixedly installed on the inner wall of the middle pipe 7, a guide plate 9 is installed on the other side of the first rotating shaft 8, a hydraulic rod 11 is installed below the guide plate 9, and a second rotating shaft 10 is installed at both ends of the hydraulic rod 11, a slag discharge hole 12 is installed on the left side of the middle pipe 7, and a clamping plate 13 is installed inside the slag discharge hole 12.
[0022] The bottom pipe 1 forms a detachable structure with the middle pipe 7 through the cooperation between the mounting pipe 2 and the mounting screw hole 3, and a sealing structure is formed between the mounting pipes 2. During use, the bottom pipe 1 can be fixed together through the mounting pipes 2 and bolts on the upper and lower sides, so that the overall length of the device can be spliced at will. At the same time, after the splicing between the mounting pipes 2 is completed, it forms a sealing structure, which can prevent the exhaust gas inside the device from leaking from the gap during the smoke exhaust process, affecting the use of the device.
[0023] The sieve plate 5 is a hollow structure, and the sieve plate 5 forms a detachable structure through the limiting plate 4. The sieve plate 5 can filter the exhaust gas discharged from the inside of the device once, so as to prevent large particles carried in the gas from being discharged from the inside of the device, resulting in the discharged gas not meeting the regulations. At the same time, the sieve plate 5 can be disassembled through the limiting plate 4, so that the sieve plate 5 can be replaced and cleaned, so as to prevent the sieve plate 5 from being blocked after long-term use.
[0024] The mounting side panels 17 and the fixed outer frame 6 are fixed to each other, and the mounting side panels 17 and the mounting rear panel 15 are welded to each other. During use, the mounting side panels 17 can improve the firmness between the fixed outer frame 6 and the device. Then, the fixed outer frame 6 is welded to each other through the mounting side panels 17 and the mounting rear panel 15, so as to improve the firmness of the device during use and prevent the device from falling from the inside of the device during use. Meanwhile, the fixed outer frames 6 are fixedly mounted on the outside of the top pipe 14, the middle pipe 7 and the bottom pipe 1, so that the overall installation of the device is more stable.
[0025] Example 2
[0026] like Figure 3 As shown, this embodiment further illustrates Example 1, the guide plate 9 forms a rotating structure through the first rotating shaft 8 and the middle pipe 7, and the guide plate 9 is in an "L"-shaped structure. During use, when the device is exhausting, the guide plate 9 is pressed downward against the inner wall of the middle pipe 7. Since the guide plate 9 is in an "L"-shaped structure, the guide plate 9 can prevent the exhaust gas from entering the gap between the guide plate 9 and the inner wall of the middle pipe 7. Then, after the smoke is exhausted, the dirt stuck to the inner wall of the device can be cleaned by blowing air into the top pipe 14. At this time, the guide plate 9 is rotated and adjusted to the side of the slag discharge hole 12 by the hydraulic rod 11, and the dirt blown from the top is introduced into the inside of the slag discharge hole 12 through the guide plate 9, and discharged from the device through the slag discharge hole 12.
[0027] The guide plate 9 forms a rotating structure with the second rotating shaft 10 and the hydraulic rod 11, and the hydraulic rod 11 forms a rotating structure with the second rotating shaft 10 and the middle pipe 7. During use, the hydraulic rod 11 can rotate inside the device through the second rotating shaft 10. When the hydraulic rod 11 is extended or retracted, it will drive the upper guide plate 9 to rotate inside the device. Then, when the hydraulic rod 11 is extended or retracted, it can rotate synchronously through the second rotating shafts 10 at both ends to adjust the angle of the guide plate 9 inside the device, thereby improving the flexibility of the device during use.
[0028] Working principle: First, the bottom pipe 1 can be fixed together with bolts through the installation pipes 2 on the upper and lower sides, so that the overall length of the device can be spliced at will. At the same time, the installation pipes 2 are sealed after being spliced, which can prevent the exhaust gas inside the device from leaking from the gap during the smoke exhaust process, affecting the use of the device. Then the sieve plate 5 can filter the exhaust gas discharged from the inside of the device, which can prevent large particles carried in the gas from being discharged from the inside of the device, causing the discharged gas to fail to meet the regulations. At the same time, the sieve plate 5 can be disassembled through the limit plate 4, so that the sieve plate 5 can be replaced and cleaned. To prevent the screen plate 5 from being blocked after long-term use, when the device is exhausting, the guide plate 9 is pressed downward against the inner wall of the middle pipe 7. Since the guide plate 9 is in an "L" shape, the guide plate 9 can prevent the exhaust gas from entering the gap between the guide plate 9 and the inner wall of the middle pipe 7. After the gas is exhausted, the dirt stuck to the inner wall of the device can be cleaned by blowing air into the top pipe 14. At this time, the guide plate 9 is rotated and adjusted to the side of the slag discharge hole 12 by the hydraulic rod 11, and the dirt blown from the top is introduced into the inside of the slag discharge hole 12 through the guide plate 9, and discharged from the device through the slag discharge hole 12.
