DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] For example, see Figure 1-4A boiler flue gas separation device comprises a separation tube 1, an air inlet pipe 2 is arranged at the bottom of the separation tube 1, an air outlet pipe 3 is arranged at the top of the separation tube 1, a protective cover 4 is arranged at the top of the air outlet pipe 3, a filtering device 5 is arranged in the inner cavity of the separation tube 1, an adsorption mechanism 6 is arranged inside the separation tube 1, the adsorption mechanism 6 comprises a guide plate 61, an adsorption plate 62 is arranged on the surface of the guide plate 61, a fixed block 63 is fixedly connected to the inner wall of the separation tube 1, a spring 64 is fixedly connected above the fixed block 63, a sliding block 65 is fixedly connected to the end of the spring 64 away from the fixed block 63, and a fixed group is arranged inside the sliding block 65 Component 66, an air pressure chamber 67 is provided in the inner wall of the separation tube 1, the air pressure chamber 67 is connected to an air bag 68, a slider 69 is slidably connected to the inner wall of the air pressure chamber 67, the slider 69 is fixedly connected to a baffle 610, the baffle 610 is slidably connected to the inner wall of the separation tube 1, a storage chamber 611 is provided in the inner wall of the separation tube 1, the storage chamber 611 is provided with a through opening connected to the inner wall of the separation tube 1, and the baffle 610 is larger than the through opening. By setting the size of the baffle 610, it is ensured that the baffle 610 can completely block the through opening, and the baffle 610 can be controlled to be in the outer area of ​​the through opening, so as to achieve the control of the baffle 611. 10 However, it does not affect the effect of the movement of the guide plate 61 and the adsorption plate 62. A replacement bin 612 is provided in the inner wall of the separation tube 1. A plurality of objects fixedly connected to the guide plate 61 and the adsorption plate 62 are placed inside the replacement bin 612. The bottom surface of the replacement bin 612 is an inclined surface. By setting the shape of the bottom surface of the replacement bin 612, it is ensured that when the guide plate 61 and the adsorption plate 62 move toward the inside of the separation tube 1, they can fit exactly with the surface of the sliding block 65. A spring 2 613 is fixedly connected to the inner wall of the replacement bin 612. The spring 2 613 is fixedly connected to a push plate 614. After the adsorption plate 62 adsorbs excessively, the gravity increases. The sliding block 65 is forced to move downward to the through hole that connects the guide plate 61 with the adsorption plate 62 and the separation tube 1 with the storage bin 611. At this time, the guide plate 61 and the adsorption plate 62 enter the storage bin 611 on the inclined surface under the action of gravity. When the guide plate 61 and the adsorption plate 62 are removed, the sliding block 65 moves upward driven by the spring 1 64. After moving to the balance area, the through hole opened in the baffle 610 allows the new combination of the guide plate 61 and the adsorption plate 62 to move inward under the joint action of the spring 2 613 and the push plate 614, thereby achieving the effect of replacing the adsorption plate 62 that has adsorbed excessively.

[0020] When in use, the staff connects the air intake pipe 2 with the exhaust pipe of the boiler, so that the smoke generated by the boiler enters the interior of the separation tube 1, so that the smoke can adsorb larger particles contained in the smoke when it contacts the adsorption plate 62. When the adsorption plate 62 adsorbs more smoke, the gravity of the adsorption plate 62 increases, so that the adsorption plate 62 drives the guide plate 61 and the sliding block 65 to move downward under the action of gravity. When the adsorption plate 62 and the guide plate 61 move to the position where the storage bin 611 is connected to the separation tube 1, the adsorption plate 62 and the guide plate 61 are moved to the interior of the storage bin 611 under the combined action of gravity and the inclination angle of the sliding block 65. At this time, the sliding block 65 is not squeezed, so the sliding block 65 moves upward under the action of the spring 64. When the sliding block 65 moves to the opening connected to the replacement bin 612 and the separation tube 1 After the lower end of the air bag 68 is flush with the position, the sliding block 65 just squeezes the air bag 68, so that the gas inside the air bag 68 enters the interior of the air pressure chamber 67, so that the slider 69 is squeezed to drive the baffle 610 to move, so that the combination of the guide plate 61 and the adsorption plate 62 inside the replacement chamber 612 is pushed to the interior of the separation tube 1 under the joint action of the spring 2 613 and the push plate 614, and is fixed to the sliding block 65 through the fixing assembly 66. At the same time, since the sliding block 65 is subjected to the gravity of the new guide plate 61 and the adsorption plate 62, the sliding block 65 moves downward a certain distance, so that the baffle 610 is automatically reset under the action of gravity. At this time, the combination of the guide plate 61 and the adsorption plate 62 above the replacement chamber 612 moves downward under the action of gravity, and moves to a position on the same plane as the spring 2 613 and the push plate 614 through the inclined surface of the push plate 614 to facilitate the next replacement.

[0021] For example 2, please refer to Figure 1-4On the basis of the first embodiment, the fixing assembly 66 includes a trapezoidal block 661, which is slidably connected to the inner wall of the sliding block 65, and a magnetic block 662 is embedded in the inner wall of the end of the guide plate 61. The trapezoidal block 661 is hinged with a connecting rod 663. The trapezoidal block 661 has magnetism, and the magnetic pole of the trapezoidal block 661 at the end away from the connecting rod 663 is the same as the magnetic pole of the magnetic block 662 at the side away from the inner wall of the guide plate 61. By setting the same magnetic pole, it is ensured that the trapezoidal block 661 will be retracted inward when approaching the front end of the guide plate 61. The guide plate 61 is retracted to ensure that the guide plate 61 can slide into the interior of the separation tube 1 without being stuck at the opening of the separation tube 1 and the replacement chamber 612 due to the obstruction of the trapezoidal block 661. The connecting rod 663 is hinged with a moving bar 664. The end of the moving bar 664 close to the connecting rod 663 is fixedly connected with a spring three 665. The end of the spring three 665 away from the moving bar 664 is fixedly connected to the inner wall of the sliding block 65. The connecting rod 663 is in a vertical state when the moving bar 664 is subjected to and only subjected to the elastic force of the spring three 665. The initial position of the connecting rod 663 is set to ensure that the trapezoidal block 661 only contracts inwards after the connecting rod 663 moves. A control block 666 is slidably connected to the inner wall of the separation tube 1. The control block 666 is in the shape of a trapezoid, and inclined surfaces are set above and below the control block 666. The inclined surfaces ensure that the sliding block 65 can push the control block 666 to move inwards during the movement, ensuring that the control block 666 does not affect the up and down movement of the sliding block 65. The control block 666 is connected to the separation tube 1 through a spring 467. The control block 666 is elastically connected to the inner wall of the separation tube 1, and is slidably connected to the inner wall of the separation tube 1. The magnetic block 662 at the front end of the guide plate 61 makes the trapezoidal block 661 contract inward when the front end of the guide plate 61 contacts the sliding block 65. After the trapezoidal block 661 moves to the rear end of the guide plate 61 to contact the sliding block 65, the trapezoidal block 661 is reset under the joint action of the spring three 665, the moving bar 664 and the connecting rod 663, thereby entering the bayonet opened on the guide plate 61, thereby achieving the fixing effect of the replaced guide plate 61 and the adsorption plate 62.

[0022] When in use, based on the first embodiment, when the newly replaced guide plate 61 and adsorption plate 62 just move to the edge of the trapezoidal block 661, the magnetic block 662 is close to the trapezoidal block 661, so that the trapezoidal block 661 moves downward under the action of the magnetic force, so that the guide plate 61 and the adsorption plate 62 can move normally. When the magnetic block 662 moves away from the trapezoidal block 661, the trapezoidal block 661 is unable to move outward due to the gravity of the guide plate 61. When the card hole under the guide plate 61 moves to the same vertical position as the trapezoidal block 661, the moving bar 664 moves toward the side away from the spring three 665 under the action of the rebound force of the spring three 665, and at the same time, through The moving bar 664 drives the connecting rod 663 to move, so that the trapezoidal block 661 moves outward and enters the card hole under the guide plate 61, thereby achieving the effect of fixing the guide plate 61. At the same time, when the adsorption plate 62 adsorbs more impurities, the sliding block 65 moves to a position where the moving bar 664 and the control block 666 are at the same horizontal position. At this time, the control block 666 pushes the moving bar 664 under the elastic force of the spring four 667, so that the moving bar 664 drives the end of the connecting rod 663 to move toward the side close to the spring three 665, thereby making the trapezoidal block 661 move downward, thereby ensuring that the guide plate 61 and the adsorption plate 62 are not hindered when moving outward.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
