[0023] Refer to Figure 1 、 Figure 2 and Figure 4 shown in the figure, the present utility model provides a technical solution: a compartment reverse blowing pressure pulse bag dust collector, including a compartment purification bin 1, an intake pipe 2 is installed on one side of the compartment purification bin 1, an exhaust pipe 3 is installed on the other side of the compartment purification bin 1, a cover plate 4 is fixedly connected to the top of the compartment purification bin 1, a bracket 5 is installed on the surface of the compartment purification bin 1, a plurality of pulse valves 6 are installed on one side of the compartment purification bin 1, a jet pipe 7 is fixedly connected to one side of the pulse valve 6, a filter bag 8 is installed inside the compartment purification bin 1, a plurality of bottom bins 9 are fixedly connected to the bottom of the compartment purification bin 1, a dust collection box 10 is slidably connected inside the bottom bin 9. The dusty gas enters the inside of the compartment purification bin 1 through the intake pipe 2, the dust in the air is adsorbed by the filter bag 8, and is discharged outward through the exhaust pipe 3. The dust on the filter bag 8 is blown by the jet pipe 7 through the activation of the pulse valve 6, and the dust is sprayed into the dust collection box 10 inside the bottom bin 9 for collection. While preventing secondary pollution of the dust, it is also convenient to recycle the recyclable substances in the dust.
[0024] Refer to Figure 2 and Figure 3As shown in the figure, in this embodiment: a storage groove 28 is provided inside the dust collection box 10, a connecting plate 11 is slidably connected inside the storage groove 28, a limiting groove 12 is provided on one side of the bottom bin 9, a limiting rod 13 is fixedly connected to one side of the connecting plate 11, and the surface of the limiting rod 13 is slidably connected to the inside of the limiting groove 12. When the dust inside the dust collection box 10 is full, by moving the connecting plate 11, the limiting rod 13 is driven to disengage from the inside of the limiting groove 12, releasing the limitation on the dust collection box 10, so that the dust collection box 10 can be taken out. After the dust inside the dust collection box 10 is processed, the dust collection box 10 is installed inside the bottom bin 9, and the connecting plate 11 is moved so that the limiting rod 13 enters the inside of the limiting groove 12 to limit the dust collection box 10 and prevent the vibration during the operation of the equipment from causing the dust collection box 10 to disengage from the inside of the bottom bin 9.
[0025] Refer to Figure 3 、 Figure 4 and Figure 5 As shown in the figure, in this embodiment: an oval block 14 is rotatably connected inside the storage groove 28, a hollow rod 15 is fixedly connected to one side of the oval block 14, a telescopic rod 19 is slidably connected inside the hollow rod 15, a knob 16 is fixedly connected to one end of the telescopic rod 19, a limiting hole 17 is provided on one side of the bottom bin 9, a limiting block 18 is fixedly connected to one side of the knob 16, and two thrust springs 23 are fixedly connected to one side of the connecting plate 11. The other end of the thrust spring 23 is fixedly connected to one side of the inner wall of the storage groove 28. By pulling the knob 16, the limiting block 18 is disengaged from the inside of the limiting hole 17, releasing the limitation on the knob 16. The knob 16 is rotated to release the limitation on the connecting plate 11. Under the thrust of the thrust spring 23, the connecting plate 11 is driven to move, so that the limiting rod 13 disengages from the inside of the limiting groove 12, and the dust collection box 10 can be pulled outwards. After the dust inside the dust collection box 10 is processed, the dust collection box 10 is installed inside the bottom bin 9. The knob 16 is rotated to drive the oval block 14 to rotate, and the connecting plate 11 is moved to make the limiting rod 13 enter the inside of the limiting groove 12. After the dust collection box 10 is limited, the knob 16 is pushed to make the limiting block 18 enter the inside of the limiting hole 17 to limit the knob 16 and prevent the thrust of the thrust spring 23 from driving the connecting plate 11 to move and cause the oval block 14 to rotate.
[0026] Refer to Figure 5 As shown in the figure, in this embodiment: a tension spring 20 is fixedly connected to one side inside the hollow rod 15, and the other end of the tension spring 20 is fixedly connected to one end of the telescopic rod 19. By installing the tension spring 20 at the rear end of the knob 16, when the limiting block 18 aligns with the position of the limiting hole 17 during the rotation of the knob 16, the tension of the tension spring 20 will pull the knob 16 to move, so that the limiting block 18 enters the inside of the limiting hole 17 to limit the knob 16.
[0027] Refer to Figure 5As shown, in this implementation: first chutes 21 are provided at both the top and bottom inside the hollow rod 15. First sliders 22 are fixedly connected to both the top and bottom of the telescopic rod 19. When the user pulls the knob 16, the first sliders 22 at the top and bottom of the telescopic rod 19 slide inside the first chutes 21 to limit the displacement of the telescopic rod 19 and prevent the telescopic rod 19 from detaching from inside the hollow rod 15, causing the knob 16 to fall off.
[0028] Refer to Figure 3 As shown, in this implementation: limiting chutes 24 are provided on both sides inside the storage groove 28. Limiting sliders 25 are fixedly connected to both sides of the connecting plate 11. When the user rotates the knob 16 to drive the connecting plate 11 to move, the limiting sliders 25 on both sides of the connecting plate 11 move inside the limiting chutes 24 to assist the movement of the connecting plate 11 and prevent the connecting plate 11 from tilting and causing movement jams.
[0029] Refer to Figure 6 As shown, in this implementation: a number of placement grooves 26 are provided at the bottom inside the bottom bin 9. Pulleys 27 are installed inside the placement grooves 26. When the user pushes and pulls the dust collection box 10, the bottom of the dust collection box 10 causes the pulleys 27 inside the placement grooves 26 to rotate, reducing the friction between the bottom of the dust collection box 10 and the bottom inside the bottom bin 9, making the movement of the dust collection box 10 more labor-saving and simultaneously reducing the wear on the bottom of the dust collection box 10.
[0030] Working principle: The dusty gas enters the interior of the compartment purification bin 1 through the intake pipe 2, adsorbs the dust in the air through the filter bag 8, and is discharged outward through the exhaust pipe 3. The dust on the filter bag 8 is blown by the air injection pipe 7 through the activated pulse valve 6 to blow the dust into the dust collection box 10 inside the bottom bin 9 for collection. While preventing secondary dust pollution, it also facilitates the recovery of recyclable substances in the dust. When the dust collection box 10 is full of dust inside, by moving the connecting plate 11, the limiting rod 13 is driven to disengage from the inside of the limiting groove 12, releasing the limit on the dust collection box 10, so that the dust collection box 10 can be taken out. After the dust inside the dust collection box 10 is processed, the dust collection box 10 is installed inside the bottom bin 9, and the connecting plate 11 is moved to make the limiting rod 13 enter the inside of the limiting groove 12 to limit the dust collection box 10 and prevent the vibration during equipment operation from causing the dust collection box 10 to disengage from the inside of the bottom bin 9. By pulling the knob 16, the limiting block 18 is driven to disengage from the inside of the limiting hole 17, releasing the limit on the knob 16. Rotating the knob 16 releases the limit on the connecting plate 11. Under the thrust of the thrust spring 23, the connecting plate 11 is driven to move, making the limiting rod 13 disengage from the inside of the limiting groove 12, so that the dust collection box 10 can be pulled outwards. After the dust inside the dust collection box 10 is processed, the dust collection box 10 is installed inside the bottom bin 9. Rotating the knob 16 drives the oval block 14 to rotate, and the connecting plate 11 moves, making the limiting rod 13 enter the inside of the limiting groove 12 to limit the dust collection box 10. Then, pushing the knob 16 makes the limiting block 18 enter the inside of the limiting hole 17 to limit the knob 16 and prevent the thrust of the thrust spring 23 from driving the connecting plate 11 to move and cause the oval block 14 to rotate. By installing a tension spring 20 at the rear end of the knob 16, when the limiting block 18 aligns with the position of the limiting hole 17 during the rotation of the knob 16, the tension of the tension spring 20 will pull the knob 16 to move, making the limiting block 18 enter the inside of the limiting hole 17 to limit the knob 16. During the process of pulling the knob 16, the first sliders 22 at the top and bottom of the telescopic rod 19 slide inside the first chute 21 to limit the displacement of the telescopic rod 19 and prevent the telescopic rod 19 from disengaging from the inside of the hollow rod 15, resulting in the knob 16 falling off. During the process of rotating the knob 16 and driving the connecting plate 11 to move, the limiting sliders 25 on both sides of the connecting plate 11 move inside the limiting chute 24 to assist the movement of the connecting plate 11 and prevent the connecting plate 11 from tilting and causing movement jams. During the process of pushing and pulling the dust collection box 10, the bottom of the dust collection box 10 rotates the pulley 27 inside the placement groove 26, reducing the friction between the bottom of the dust collection box 10 and the bottom inside the bottom bin 9, making the movement of the dust collection box 10 more labor-saving, and at the same time reducing the wear on the bottom of the dust collection box 10.
