[0022] A motor 39 is fixedly connected to the front of the corresponding rectangular plate 34, and the output shaft of the motor 39 is fixedly connected to a rotating shaft 391 through a coupling. The rotating shaft 391 passes through the two rectangular plates 34 and is rotatably connected to the two rectangular plates 34. A cam 392 is fixedly sleeved on the outer wall of the rotating shaft 391, and the cam 392 is adapted to the sliding plate 36. A mounting groove 393 is provided on the front of the dust removal box 1, and a collecting box 394 is slidably connected to the inner wall of the mounting groove 393. A smoke exhaust pipe 395 is fixedly connected to the right side of the dust removal box 1, and the smoke exhaust pipe 395 is communicated with the dust removal box 1.

[0023] By setting up a dust cleaning mechanism, if the filter bag needs to be cleaned after long-term use, the motor 1 can be started. After the motor 1 is started, it will drive the rotating shaft 1 and the cam to rotate synchronously. At the same time, the cam will contact the sliding plate during the rotation. In this way, the sliding plate will use two sliding rods to drive the filter bag on the slide plate to vibrate up and down. Through this vibration method, the dust on the filter bag can be shaken off, effectively preventing the dust from clogging the filter bag, thereby avoiding affecting the filtration efficiency.

[0024] The lifting mechanism 4 includes a base plate 41 arranged at the bottom of the dust removal box 1, and a plurality of sleeves 42 are fixedly connected to the top of the base plate 41, and the inner walls of the plurality of sleeves 42 are slidably sleeved with gear rods 43, and the top ends of the plurality of gear rods 43 are fixedly connected to the dust removal box 1, and a plurality of U-shaped rods 44 are fixedly connected to the top of the base plate 41, and two rotating rods 45 are rotatably connected to the plurality of U-shaped rods 44, and the outer walls of the two rotating rods 45 are fixedly sleeved with two gears 46, and the plurality of gears 46 are meshed with the plurality of gear rods 43, and a motor 2 47 is fixedly connected to the top of the base plate 41, and the output shaft of the motor 2 47 is fixedly connected to a rotating shaft 2 48 through a coupling, and the outer walls of the rotating shaft 2 48 and the two rotating rods 45 are fixedly sleeved with pulleys 49, and the outer walls of the plurality of pulleys 49 are wrapped with belts 491.

[0025] By setting up a lifting mechanism, when connecting the pipe, if the smoke exhaust port is too high or too low and thus difficult to connect, the second motor can be started. After the second motor is started, it will drive the second shaft to rotate. At the same time, when the second shaft rotates, it will cooperate with multiple pulleys and belts, so that the two rotating rods can rotate synchronously with the second shaft, and when the two rotating rods rotate, they will engage with the gear rods in the sleeve. In this way, the multiple gear rods can drive the dust removal box thereon to adjust to a suitable height, which is convenient for installing the smoke inlet pipe. Through this setting, the adaptability of the device in different installation environments can be greatly improved, making the installation process more convenient and efficient.

[0026] When in use, firstly, the connector 22 on the delivery pipe can be plugged into the smoke inlet pipe 21 on the dust removal box 1. After the plugging is completed, the half hoop 1 24 and the half hoop 25 are sleeved on the joint of the smoke inlet pipe 21 and the connector 22. After the sleeve connection is completed, the threaded rod 27 rotated on the half hoop 1 24 is inserted into the slot 28 on the half hoop 25, and the threaded rod 27 is retracted by rotating the turntable 29 on the threaded rod 27. In this way, the half hoop 1 24 and the half hoop 25 can quickly complete the connection between the smoke inlet pipe 21 and the connector. The connection of the joint 22 greatly reduces the cumbersome process of pipeline installation and disassembly, thereby significantly improving the installation efficiency; after the pipeline is connected, the smoke generated by power generation can enter the dust removal box 1. After the smoke enters, it will pass through a series of filter bags 33 suspended in the dust removal box 1. When the smoke particles in the exhaust gas pass through the filter bag, they will be blocked on the filter bag because their particle size is larger than the pores of the filter bag, while the clean gas can pass through the pores of the filter bag, thereby realizing the separation of smoke and gas. The separated clean gas can be discharged through the exhaust pipe 395.

[0027] If the filter bag 33 needs to be cleaned after being used for a long time, the motor 39 can be started. After the motor 39 is started, it will drive the rotating shaft 391 and the cam 392 to rotate synchronously. At the same time, the cam 392 will contact the sliding plate 36 during the rotation. In this way, the sliding plate 36 will use the two sliding rods 37 to drive the filter bag 33 on the slide plate 32 to vibrate up and down. Through this vibration method, the dust on the filter bag 33 can be shaken off, effectively preventing the dust from clogging the filter bag 33, thereby avoiding affecting the filtering efficiency.

[0028] Then, the fallen dust can be collected in the collection box 394 by utilizing the slope design of the inner wall of the dust removal box 1. When the collection box 394 needs to be cleaned, the collection box 394 can be disassembled by simply pulling it outward, so that it can be cleaned separately. At the same time, when the two slide bars 37 drive the slide plate 32 to vibrate up and down, the sealing ring 38 on the slide bar 37 can seal it to prevent the dust in the dust removal box 1 from overflowing from the activity space. When connecting the pipe, if the smoke exhaust port is too high or too low and is difficult to connect, the motor can be started. 247, after the motor 247 is started, it will drive the rotating shaft 248 to rotate. At the same time, when the rotating shaft 248 rotates, it will cooperate with multiple pulleys 49 and belts 491, so that the two rotating rods 45 can rotate synchronously with the rotating shaft 248, and when the two rotating rods 45 rotate, they will engage with the gear rods 43 in the sleeve 42. In this way, the multiple gear rods 43 can drive the dust removal box 1 thereon to adjust to a suitable height, which is convenient for installing the smoke inlet duct. Through this arrangement, the adaptability of the device in different installation environments can be greatly improved, making the installation process more convenient and efficient.
