[0029] The sealing part 5 includes a rotating door 501, a rotating base 502, a rotating handle 503, a rotating threaded member 504 and a threaded rod 505; a through hole is provided on the side of the shell 1, and the rotating door 501 is covered on the outer end face of the through hole, and the rotating door 501 is rotatably connected to the outer end face of the shell 1; the outer end face of the shell 1 is rotatably connected to the rotating base 502, and a supporting column is provided on the rotating base 502, and a rotating threaded member 504 is provided on the top of the supporting column, and the end of the rotating threaded member 504 away from the supporting column is threadedly connected to the threaded rod 505, the top of the threaded rod 505 is connected to the rotating handle 503, and the bottom of the threaded rod 505 is in contact and extruded with the outer end face of the rotating door 501; the inner wall of the rotating door 501 is connected to the detection shell 8.

[0030] A rubber sealing ring is provided on the top of the sliding column 10 , and the rubber sealing ring contacts and squeezes the inner wall side of the through hole at the top of the detection housing 8 .

[0031] A sliding protrusion is provided on the side surface of the filter screen 4, and a sliding groove is provided on the side surface of the inner wall of the shell 1, and the sliding protrusion is slidably connected with the sliding groove.

[0032] A symmetrical sealing member is provided on one end of the blocking plate 6 away from the rotating shaft 202 , and the sealing member is in contact and pressed against the sealing abutment member 7 .

[0033] A rotation blocking member is provided on the side of the housing 1 , and the rotation blocking member is rotationally connected to the side of the rotating door 501 .

[0034] The side surface of the sliding column 10 is provided with scale lines at equal intervals, and the sliding sensor 12 faces the direction of the scale lines.

[0035] In this embodiment, the device can effectively improve the stability and emission efficiency of the flue gas emission process. Compared with traditional devices, the device does not need to be shut down for maintenance, thereby achieving the effect of continuous operation of the device.

[0036] When the device is in working condition, the top of the shell 1 is connected to the exhaust gas end of the kiln. At this time, the blocking plate 6 is tilted toward one side and contacts and squeezes the sealing abutment member 7 at one end. At this time, the exhaust gas enters the interior of the device. Through the guiding effect of the blocking plate 6, the exhaust gas can be discharged from the outlet on one side of the bottom of the shell 1. At this time, the filter screen 4 on the outlet side is in working condition.

[0037] When the filter 4 on the air outlet side has been used continuously for a period of time, the flow velocity of the flowing air flow inside the shell 1 is reduced when passing through the filter 4 due to the blockage of dust. The blockage effect causes the gas pressure inside the shell 1 to increase. At this time, as the air pressure inside the shell 1 increases, the sliding column 10 slides downward under the increased air pressure to squeeze the airbag 9. The air pressure inside the airbag 9 is the standard atmospheric pressure. Therefore, after the air pressure inside the shell 1 increases, the air pressure inside the airbag 9 is less than the flowing air pressure inside the shell 1. At this time, the sliding column 10 slides downward to squeeze the airbag 9, so that the airbag 9 is squeezed, thereby increasing the air pressure inside the airbag 9, and achieving the effect of dynamic balance again. The sliding degree of the sliding column 10 is detected by the sliding sensor 12, so that the current degree of increase in the air pressure inside the shell 1 can be determined.

[0038] When the air pressure inside the shell 1 rises to a certain level, the sliding sensor 12 sends out an alarm to facilitate the staff to replace it in time, and at this time, the telescopic rod 206 drives the transmission slide 205 to perform a linear sliding that first rises and then falls, so that the transmission shaft 204 can be driven to rotate in an arc-shaped swing through the structure of the transmission slide 205, and the transmission effect of the transmission shaft 204 on the rotating connecting rod 203 is ensured, thereby ensuring the transmission effect of the device on the rotating shaft 202, and the rotation of the blocking plate 6 is driven by the rotating shaft 202. The symmetrical sealing abutment member 7 structure on the inner wall of the shell 1 can be used to limit the side of the blocking plate 6. The telescopic rod 206 can drive the blocking plate 6 to rotate and tilt to the other side, thereby realizing the switching of the air outlet of the device, so that the filter 4 on the other side begins to be used, and the originally blocked filter 4 is out of working state. At this time, the staff can replace the filter 4 on the outside of the shell 1, and the exhaust gas is purified and exhausted through the air outlet and the filter 4 on the other side, and the device can be maintained and replaced without stopping.

[0039] When the detection shell 9 has been used for a long time, the threaded rod 505 can be driven to rotate by rotating the rotating handle 504, so that the threaded rod 505 is away from the rotating door 501 to achieve the unlocking effect of the device. When the threaded rod 505 is not in contact with the rotating door 501, the rotating connection structure between the rotating base 501 and the supporting column can make the rotating threaded member 504 rotate to the side that does not block the rotating door 501, thereby facilitating the opening of the rotating door 501. The inner wall of the rotating door 501 is connected to the detection shell 9, so that the detection shell 9 is brought out during the opening process of the rotating door 501, so that the airbag 10 and other structures inside the detection shell 9 are easy to replace from the outside of the shell 1, thereby reducing the maintenance difficulty of the device. After the replacement is completed, the rotating door 501 is closed, and the threaded rod 505 is pressed against the rotating door 501, thereby avoiding exhaust gas leakage from the rotating door 501.

[0040] The blocking plate 3 and the filter 4 can facilitate the replacement of the filter 4 of the device. At the same time, the structure of the rotating door 501 can facilitate the replacement of the detection shell 8 of the device, thereby avoiding the problem that the air bag 9 hardens over time and causes the air pressure detection accuracy to decrease, thereby avoiding the need to disassemble the shell 1 as a whole when the air bag 9 needs to be replaced.

[0041] Embodiment 2

[0042] like Figure 1-Figure 4 As shown, the utility model proposes a new gate device for kiln flue gas treatment. Compared with the first embodiment, in this embodiment, a symmetrical seal is provided on the end of the baffle plate 6 away from the rotating shaft 202, the seal is in contact and squeezed with the sealing abutment 7, and the transmission slide groove 205 is obliquely arranged at the bottom of the telescopic rod 206.

[0043] It is ensured that no exhaust gas leakage occurs on the other side during the switching process of the air outlet of the device, and the accuracy of the switching of the air outlet of the device is ensured. The inclined setting of the transmission slot 205 can prevent the transmission from getting stuck when the blocking plate 6 is in a vertical state. Through the inclined transmission slot 205, a tangential force can be generated on the transmission shaft 204 when the rotating connecting rod 203 is in a vertical state, thereby breaking the force balance in the vertical state and allowing the rotating connecting rod 203 to continue to rotate.
