The lower end of the dust bag 14 is fixed on the limiting sleeve 11. A closing mechanism 21 for opening and closing each limiting sleeve 11 is provided in the dust collecting chamber 7. The rapper 17 is arranged in the lower part and / or the upper middle part of the dust collecting chamber 6, and the rapper 17 is connected to each dust bag 14.
[0018] The dust bag 14 is coaxially arranged with two layers, and a support ring 16 is axially provided between the outer layer and the inner layer of the dust bag 14. The width of the support ring 16 is not less than 3 cm to ensure that there is enough space between the outer layer and the inner layer of the dust bag 14 to avoid the outer layer and the inner layer being closely attached together. The double-layer structure can increase the dust collection area, capture escaped dust, and greatly improve the dust collection efficiency.
[0019] The closing mechanism 21 includes a lifting drive member 22, a closing bracket 23 and a sleeve plug 24. The lifting drive member 22 is symmetrically arranged at the inner bottom or outer bottom on both sides of the dust collecting chamber 7. A closing bracket 23 is arranged on the top thereof, and the closing bracket 23 is in the dust collecting chamber 7. A sleeve plug 24 is arranged on the closing bracket 23 corresponding to each limiting sleeve 11, and a dust hole 25 is arranged on the closing bracket 23 to ensure that the dust on the dust bag 14 can fall into the dust collecting chamber 7 through the dust hole 25 on the closing bracket 23.
[0020] The sleeve plug 24 is arranged in a "V" shape, and the lifting drive member 22 is a cylinder or a hydraulic cylinder. When collecting dust, the sleeve plug 24 blocks the lower part of the limiting sleeve 11 to prevent the gas from directly entering the dust collecting bag 14 through the limiting sleeve 11, causing the gas to be discharged without being filtered.
[0021] The mounting sleeve 10 and the limiting sleeve 11 are respectively concentric circular structures formed by two circular tubes 12 coaxially arranged, and the two circular tubes 12 are connected and fixed by a support rod 13; wherein, the inner circular tube 12 of the mounting sleeve 10 passes through the mounting through hole 15 of the upper bracket 8 upward and is fixed to the top of the upper bracket 8, and the top of the outer circular tube 12 is sealed and connected to the inner circular tube 12, and the outer layer and the inner layer of the upper end of the dust bag 14 are respectively correspondingly sleeved on the outer circular tube 12 and the inner circular tube 12 of the mounting sleeve 10, and the outer circular tube 12 of the limiting sleeve 11 passes through the mounting through hole 15 of the lower bracket 9 downward and is fixed to the bottom of the lower bracket 9, and the outer layer and the inner layer of the lower end of the dust bag 14 are respectively correspondingly sleeved on the outer circular tube 12 and the inner circular tube 12 of the limiting sleeve 11.
[0022] The two side walls of the dust collecting chamber 7 are respectively provided with lifting guide rails 26 adapted to the lower bracket 9. The lifting guide rails 26 are connected to the lower bracket 9 through sliders. A lifting drive member 22 is provided on the side wall of the dust collecting chamber 7 at the upper or lower end of each lifting guide rail 26 to connect the lower bracket 9. The lifting and lowering of the lower bracket 9 is controlled by the lifting drive member 22 to adjust the height of the dust bag 14, so that the dust bag 14 is appropriately bent during cleaning, which makes it more convenient for the vibrator 17 to drive the dust bag 14 to shake, thereby shaking off the dust more quickly and effectively.
[0023] The rapper 17 includes a vibration frame 18, a rapping guide rail 19, and a rapping drive member 20. The rapping guide rail 19 is horizontally arranged on any two opposite side walls of the dust collecting chamber 7. The vibration frame 18 is arranged on the rapping guide rail 19 through a slider. A limiting ring 27 is arranged on the vibration frame 18 corresponding to each dust collecting bag 14. A gap is arranged between adjacent limiting rings 27. The gap is a dust-permeable hole 25 for dust falling. The dust collecting bag 14 passes downward through the limiting ring 27. A rapping drive member 20 is arranged on the outer wall of the dust collecting chamber 7 at either end of the rapping guide rail 19. The rapping drive member 20 penetrates into the dust collecting chamber 7 and connects to the vibration frame 18, driving the vibration frame 18 to make horizontal reciprocating motion. The vibration frame 18 pulls each dust collecting bag 14 to shake, thereby shaking off the dust on the outer wall of each dust collecting bag 14 to achieve cleaning.
[0024] The rapping drive member 20 is a pneumatic cylinder or a hydraulic cylinder. The vibration frame 18 is provided with a dust hole 25. The inner diameter of the limiting ring 27 is larger than the outer diameter of the dust bag 14 to ensure that the dust on the dust bag 14 can fall into the dust collecting chamber 7 through the dust hole 25 on the vibration frame 18.
[0025] The lower bracket 9 is a grid-like structure, and the gaps or spaces between adjacent limiting sleeves 11 are dust holes 25 of the lower bracket 9 to ensure that dust on the dust bag 14 can fall into the dust collecting chamber 7 through the dust holes 25 on the lower bracket 9.
[0026] The vibration frame 18 is a grid-like structure, and the gaps or spaces between adjacent limiting rings 27 are dust holes 25 of the vibration frame 18 to ensure that dust on the dust bag 14 can fall into the dust collecting chamber 7 through the dust holes 25 on the vibration frame 18 .
[0027] The working mode of the utility model is as follows: the gas containing dust enters the upper part of the dust collecting chamber 7 of the dust collecting box 1 from the air inlet 3, passes through the lower bracket 9 and enters the dust collecting chamber 6 to contact each dust collecting bag 14, and the gas passes through the outer layer and the inner layer of the dust collecting bag 14 in turn and enters the discharge chamber 5, and is discharged through the exhaust port 4; the dust is blocked and adheres to the outer wall of the outer layer of the dust collecting bag 14, and a small amount of dust entering the outer layer of the dust collecting bag 14 is blocked by the inner layer and adheres to the outer wall of the inner layer;
[0028] When it is necessary to clean the dust attached to the dust bag 14, the lifting drive member 22 is started to lift the lower bracket 9, and the lower bracket 9 lifts the dust bag 14 upward, so that the dust bag 14 changes from a straight state to a curved state, thereby facilitating the operation of the rapper 17 and avoiding damage by the rapper 17. The lifting drive member 22 is started to lift the closed bracket 23 to rise with the lower bracket 9, and the sleeve plug 24 is kept to block the limiting sleeve 11, so as to avoid dust from entering the inner layer of the dust bag 14 during the operation of the rapper 17;
[0029] Subsequently, the rapping drive member 20 is started to drive the vibration frame 18 to reciprocate on the rapping guide rail 19, thereby driving each dust collecting bag 14 to shake and shake off the dust, and the dust passes through the vibration frame 18, the lower bracket 9, and the closed bracket 23 and falls into the dust collecting chamber 7, and is finally discharged through the dust discharge port 2. After the operation of the rapper 17 is completed, the lifting drive member 22 is started to pull the closed bracket 23 down, so that the sleeve plug 24 opens the lower end of the limiting sleeve 11, and the dust in the inner layer of the dust collecting bag 14 is discharged into the dust collecting chamber 7;
[0030] Finally, the lifting drive member 22 is started to pull the lower bracket 9 down and reset, so that the dust collecting bag 14 is restored to its original state, and the sleeve plug 24 is kept blocking the limiting sleeve 11, and the dust cleaning operation is completed.
