[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] Reference Figures 1 to 7As shown, a detachable and movable dust hood adapter device of an embodiment of the utility model comprises: a flue gas main pipe 100, a sealing belt 300, a bracket 400, a collecting pipe 500, and a movable air duct mechanism 600. The flue gas main pipe 100 is a square steel pipe. A ventilation hole 110 extending along the length direction of the flue gas main pipe 100 is provided at the upper end of the flue gas main pipe 100. It can be foreseen that the ventilation hole 110 will affect the torsional strength of the flue gas main pipe 100, so the welding reinforcement ribs at the bottom of the flue gas main pipe 100 can improve the mechanical strength of the flue gas main pipe 100. The flue gas main pipe 100 is connected to an induced draft fan 200; the induced draft fan 200 is used to extract the gas from the flue gas main pipe 100 and form a negative pressure in the flue gas main pipe 100. The induced draft fan 200 uses a centrifugal fan driven by a three-phase asynchronous motor 440. The sealing belt 300 is located at the upper end of the flue gas main pipe 100, and the sealing belt 300 is made of high temperature resistant rubber. The width of the sealing belt 300 is greater than the width of the ventilation hole 110 so that the sealing belt 300 can seal the ventilation hole 110. Due to the negative pressure in the smoke main pipe 100, the sealing belt 300 is pressed against the upper end of the smoke main pipe 100 under the push of the external atmospheric pressure to achieve the sealing of the ventilation hole 110. The bracket 400 is slidably connected to the guide rail 410, and the bracket 400 moves with the guide rail 410. The length of the ventilation hole 110 is not less than the travel of the bracket 400. The guide rail 410 is parallel to the smoke main pipe 100, and two guide plates 420 for collecting smoke are obliquely arranged on the bracket 400. Due to the high temperature of the smoke, it will flow upward, and the guide plate 420 will guide the smoke to the collection pipe 500. The guide plate 420 is made of colored steel tiles or tinplate. The collection pipe 500 is horizontally bolted to the bracket 400 for collecting smoke. The guide plate 420 is connected to the bracket 400 by bolts. The upper end of the guide plate 420 is connected to the opening edge of the lower end of the collecting pipe 500; the movable air duct mechanism 600 is slidably connected to the smoke main pipe 100 and can move along the smoke main pipe 100. The movable air duct mechanism 600 can lift up part of the sealing belt 300 and communicate with the smoke main pipe 100 through the ventilation hole 110 below the part of the sealing belt 300, and the end of the movable air duct mechanism 600 away from the smoke main pipe 100 is connected to the collecting cover. When the bracket 400 moves along the guide rail 410, the collecting pipe 500 drives the movable air duct mechanism 600 to move along the smoke main pipe 100. After the bracket 400 moves to the top of the smoke generation, the movable air duct mechanism 600 plays a role of sliding sealing, and the induced draft fan 200 collects the smoke collected by the guide plate 420 through the smoke main pipe 100 and the collecting pipe 500.

[0041] Reference Figures 1 to 5As shown, it can be understood that four pulleys 430 are symmetrically arranged at the bottom end of the bracket 400, and two guide rails 410 are arranged. Two pulleys 430 are matched with one guide rail 410 as a group. The side wall of the pulley 430 is provided with a groove, and the guide rail 410 is embedded in the groove. The pulley 430 cooperates with the guide rail 410 to limit the bracket 400. The pulley 430 is against the guide rail 410, and the front end of the bracket 400 is connected to the motor 440 connected to the pulley 430. The pulley 430 can also reduce the friction when the bracket 400 moves. The motor 440 drives the pulley 430 to rotate, thereby driving the bracket 400 to move along the guide rail 410.

[0042] Reference Figure 2 and Figure 3 As shown, it can be understood that a protective plate 700 is bolted to one side of the bracket 400 close to the flue gas main pipe 100, the upper end of the protective plate 700 is connected to the guide plate 420, and the lower end of the protective plate 700 extends to the bottom of the bracket 400. The protective plate 700 is used to prevent high-temperature flue gas from contacting the motor 440. The protective plate 700 can also play a role in assisting the collection of flue gas. Since the operating temperature of the motor 440 and the wires connected to the motor 440 cannot be too high, the bracket 400 needs to be moved to the high-temperature working area to collect flue gas. In order to prevent high-temperature flue gas from contacting the motor 440 and to isolate the heat radiation from the high-temperature working area, a protective plate 700 is set to protect the motor 440.

[0043] Reference Figures 1 to 7 As shown, it can be understood that the mobile air duct mechanism 600 includes a box body 610 and two pressing rollers 620. The box body 610 is slidably connected to the upper end of the smoke main pipe 100 and is located between the sealing belt 300 and the smoke main pipe 100. The box body 610 is formed by welding steel plates. A downwind port 611 connected to the ventilation hole 110 is provided at the lower end of the box body 610. The width of the downwind port 611 is not less than the width of the ventilation port. The smoke in the box body 610 enters the smoke main pipe 100 through the downwind port 611 and the ventilation port. The rear end of the box body 610 is connected to the collection pipe 500. The smoke in the collection pipe 500 enters the box body 610. The two pressing rollers 620 are rotatably mounted on the lower sides of the left and right ends of the box body 610. The pressing rollers 620 are used to press the sealing belt 300 against the upper end of the smoke main pipe 100. When the box body 610 moves, the sealing belt 300 in the forward direction is lifted up, and the sealing belt 300 originally lifted up by the box body 610 is re-attached to the upper end of the flue gas main pipe 100 under the action of the pressing roller 620.

[0044] Reference Figures 1 to 7As shown, it can be understood that the upper sides of the left and right ends of the box body 610 are both rotatably mounted with redirection rollers 612, and the two redirection rollers 612 are used to reduce the friction force of the sealing belt 300 when it moves on the box body 610. As the box body 610 moves along the smoke main pipe 100, the sealing belt 300 passes through the upper end of the box body 610 and generates resistance by friction with the upper end of the box body 610, and the redirection rollers 612 play a role in supporting the sealing belt 300. By rotating the redirection rollers 612, the friction force between the sealing belt 300 and the upper end of the box body 610 is reduced. Thereby reducing the resistance of the box body 610 when it moves along the smoke main pipe 100.

[0045] Reference Figures 4 to 7 As shown, it can be understood that two moving rollers 613 are rotatably installed at the bottom of the box body 610, and the moving rollers 613 are against the upper end of the smoke main pipe 100. The moving rollers 613 can reduce the friction force when the box body 610 moves along the smoke main pipe 100. The moving rollers 613 can also assist in guiding the sealing belt 300. The moving rollers 613 are made of high temperature resistant materials.

[0046] Reference Figures 1 to 7 As shown, it can be understood that both the front and rear ends of the box body 610 are connected with a downwardly extending limit plate 614, and the bottom end height of the limit plate 614 is less than the top end height of the smoke main pipe 100, so that the smoke main pipe 100 is at least partially sandwiched between the two limit plates 614. A roller 615 is rotatably installed on the side where the two limit plates 614 are close to each other, and the rollers 615 of the two limit plates 614 are respectively against the front and rear ends of the smoke main pipe 100. When the box body 610 moves along the smoke main pipe 100, the roller 615 is against the smoke main pipe 100, limiting the front and rear directions of the box body 610 to prevent the box body 610 from being misaligned with the smoke main pipe 100.

[0047] Reference Figures 1 to 7 As shown, it can be understood that a plurality of partitions 616 are welded inside the box body 610, and the partitions 616 are vertically arranged to prevent the smoke inside the box body 610 from generating turbulence. The partitions 616 are arranged at equal intervals in the left-right direction, and the plurality of partitions 616 are parallel to each other. The partitions 616 divide the space inside the box body 610 into small-diameter flow channels, so that the smoke can flow in the box body 610 in an orderly manner, reducing the flow resistance of the smoke in the box body 610. Thus, the energy consumption of the induced draft fan 200 is reduced.

[0048] Reference Figures 1 to 7 As shown, it can be understood that a plurality of lifting ears 617 are welded on the upper end of the box body 610. The lifting ears 617 facilitate the use of lifting equipment to install and remove the box body 610 to improve maintenance efficiency.

[0049] Reference Figures 1 to 7As shown, it can be understood that the lower end of the box body 610 is bolted with a bending plate 800, and the bending plate 800 is located between the pressing roller 620 and the moving roller 613, and the distance between the bending plate 800 and the pressing roller 620 does not exceed 3 cm. The bending plate 800 is used to reduce the gap between the sealing bag and the side of the box body 610, reduce air leakage, and thus reduce the energy consumption of the induced draft fan 200.

[0050] Working principle: When smoke is generated at a certain location and needs to be collected, start the motor 440, which drives the pulley 430 to rotate and drives the bracket 400 to move to the designated location along the guide rail 410. During the movement of the bracket 400, the box body 610 moves with the bracket 400, and lifts up the sealing belt 300 in the forward direction. The sealing belt 300 originally lifted up by the box body 610 is re-attached to the upper end of the smoke main pipe 100 under the action of the pressing roller 620. It plays the role of sliding seal. Then start the induced draft fan 200, and the smoke is gathered by the guide plate 420 and enters the collection pipe 500, and then enters the induced draft fan 200 through the box body 610 and the smoke main pipe 100 for discharge. The smoke leaving the induced draft fan 200 can be sent to the subsequent purification process or directly sent to the chimney for discharge.

[0051] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
