Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, and more specifically, to a low-pressure dust collector. Background Art

[0002] A dust collector is a dust removal device used to remove dust, particulate matter and other solid pollutants from gases. When cleaning dust, a low-pressure pulse bag dust collector usually uses its own air bag and pulse valve to generate impact force to back-blow the filter bag to shake off the dust. However, in the process of back-blow cleaning of the filter bag by the existing low-pressure dust collector, the impact force generated by the gas is relatively small when it reaches the bottom of the filter bag, and the dust at the bottom of the filter bag cannot be completely shaken off, thereby reducing the cleaning effect of the entire filter bag; secondly, during the use of the existing low-pressure dust collector, the dust filtered out by the filter bag will directly fall to the bottom of the dust collector and then be discharged from the ash discharge pipe into the collection box, and the ash discharge pipe cannot be adjusted in height according to the height of the collection box, so that there is a distance between the ash discharge pipe and the collection box, so that during the ash discharge process, the dust will fly back into the air, polluting the surrounding working environment and reducing the dust removal effect.

[0024] according to Figure 1-5As shown, a low-pressure dust collector comprises a box body 1, wherein a flower plate 2, a filter bag 3, a frame 4 and a blowing pipe 5 are arranged in the box body 1, a movable frame 6 is movably arranged in the box body 1, a lead screw 7 rotatably connected to the box body 1 is threadedly connected on the movable frame 6, a first motor 9 is fixedly arranged on one side of the box body 1, a driving end of the first motor 9 passes through the box body 1 and is fixedly connected to a convex column 8 rotatably connected to the box body 1, one end of the lead screw 7 passes through the box body 1 and is connected to a first transmission belt structure 10 between the driving end of the first motor 9 and the driving end thereof, a top plate 11 is movably arranged in the movable frame 6, two vibration rods 12 are fixedly arranged on the upper end of the top plate 11, a spring 13 is movably sleeved on the outer side of each of the vibration rods 12, the upper ends of the two vibration rods 12 pass through the movable frame 6 and are fixedly connected to a vibration frame 14, a plurality of rotating rods 15 are rotatably arranged on the vibration frame 14; a ash discharge pipe 16 is arranged in a fixed chamber at the lower end of the box body 1, a lifting pipe 17 is movably arranged on the outer side of the ash discharge pipe 16, and a collecting box 18 is movably connected to the lifting pipe 17.

[0025] In this embodiment, after the filter bag 3 is back-blown for dust removal, the first motor 9 is started, and the first motor 9 drives the convex column 8 to rotate. When the protruding part of the convex column 8 rotates to contact with the top plate 11, the top plate 11 is pushed upward as the convex column 8 rotates, and the top plate 11 drives the two vibration rods 12 to move upward. The spring 13 is compressed, and the vibration rod 12 drives the vibration frame 14 and the rotating rod 15 to move upward. When the convex column 8 rotates to a state separated from the top plate 11, the top plate 11 drives the vibration rod 12, the vibration frame 14 and the rotating rod 15 to move downward under the action of the spring 13. Such repeated operations cause the vibration frame 14 and the rotating rod 15 to vibrate up and down continuously. When the first motor 9 is started, the lead screw 7 is driven to rotate through the first transmission belt structure 10, so that the movable frame 6 drives the vibration frame 14 and the rotating rod 15 to move while vibrating. The rotating rod 15 contacts the bottom of the filter bag 3 while vibrating and moving and continuously knocks the skeleton 4, so that the skeleton 4 drives the filter bag 3 to vibrate, thereby vibrating off the dust at the bottom of the filter bag 3. The rotating rod 15 rotates when in contact with the filter bag 3, thereby reducing friction. More specifically, when the filter bag 3 is dusted, the rotating rod 15 moves while vibrating, thereby vibrating and cleaning the bottom of the filter bag 3. The lifting pipe 17 moves up and down outside the ash discharge pipe 16, so that the lifting pipe 17 is inserted into the collection box 18. During the ash discharge process of the ash discharge pipe 16, the lifting pipe 17 and the collection box 18 are tightly connected.

[0026] according to Figure 3 As shown, as an implementation method for limiting the position of the mobile frame 6: two limiting rods 19 are fixedly provided in the box body 1, and the two limiting rods 19 are slidably connected to the mobile frame 6. Specifically, when the mobile frame 6 moves, it moves along the two limiting rods 19, thereby limiting the position of the mobile frame 6.

[0027] according to Figure 1-2 As shown, as an implementation method for simultaneously rotating the two screw rods 22: the second motor 20 and two mounting seats 21 are fixedly provided at the lower end of the box body 1, and a screw rod 22 is rotatably provided at the lower end of each mounting seat 21, and a second transmission belt structure 23 is respectively connected between the two screw rods 22 and the driving end of the second motor 20. Specifically, the second motor 20 is started, and the second motor 20 drives the two screw rods 22 to rotate simultaneously through the second transmission belt structure 23.

[0028] according to Figure 1-2 As shown, as an implementation method for moving the lifting seat 24: each screw rod 22 is threadedly connected with a lifting seat 24, and the two lifting seats 24 are fixedly connected to the lifting tube 17. Specifically, when the screw rod 22 rotates, the lifting seat 24 drives the lifting tube 17 to move downward.

[0029] according to Figure 1-5 As shown in the figure, as an implementation method for inserting the lifting tube 17 into the collection box 18: the upper end of the collection box 18 is hingedly connected to a cover 25, and the cover 25 is provided with a plug hole 26 that matches the lifting tube 17. Specifically, when the lifting tube 17 moves downward, the lower end of the lifting tube 17 is inserted into the plug hole 26, and the cover 25 can be rotated, so that the hinged connection between the cover 25 and the collection box 18 rotates, thereby opening the collection box 18 for cleaning.

[0030] according to Figure 1-5 As shown, as an implementation method for supporting the support plate 28: four support columns 27 are symmetrically arranged at the lower end of the box body 1, and a support plate 28 is fixedly connected between every two support columns 27. Specifically, the support columns 27 support the support plate 28.

[0031] according to Figure 1-5 As shown, as an implementation method for moving the fixed plate 30: an electric push rod 29 is fixedly provided on one side of the support plate 28, and the driving end of the electric push rod 29 passes through the support plate 28 and is connected to the fixed plate 30. Specifically, the electric push rod 29 is started, and the electric push rod 29 drives the fixed plate 30 to move.

[0032] according to Figure 1-5 As shown, as an implementation method for fixing the collection box 18: the collection box 18 is provided with two fixing grooves 31 that match with the fixing plate 30. Specifically, when the fixing plate 30 moves into the fixing grooves 31, the collection box 18 can be positioned and fixed.

[0033] In summary, when the overall equipment is in use:

[0034] When the collecting box 18 needs to be fixed, a roller is provided at the lower end of the collecting box 18 to push the collecting box 18 so that the collecting box 18 moves to the bottom of the ash discharge pipe 16. At the same time, the two electric push rods 29 are started, and the electric push rods 29 drive the fixing plate 30 to move so that the fixing plate 30 moves to the fixing groove 31 to position and fix the collecting box 18. At this time, the socket 26 is located below the lifting tube 17.

[0035] When the lifting tube 17 needs to be inserted into the collection box 18, the second motor 20 is started, and the second motor 20 drives the two screws 22 to rotate simultaneously through the second transmission belt structure 23, so that the lifting seat 24 drives the lifting tube 17 to move downward and insert it into the collection box 18 through the insertion hole 26. On the contrary, when the collection box 18 needs to be cleaned, the second motor 20 is started, so that the second motor 20 is reversed and the lifting tube 17 is moved out of the collection box 18. The electric push rod 29 is started to move the fixing plate 30 from the fixing groove 31. After the collection box 18 is moved, the cover body 25 can be rotated, so that the hinged connection between the cover body 25 and the collection box 18 rotates, so that the collection box 18 is opened for cleaning.

[0036] When the filter bag 3 needs to be back-blown and cleaned, an air inlet pipe is provided on one side of the box body 1 and an air outlet pipe is provided on the other side. The gas that needs to be dusted enters the box body 1 from the air inlet pipe and passes through multiple filter bags 3 for filtration and dust removal. The dust-removed air is discharged from the air outlet pipe. When the filter bag 3 needs to be dusted, an air bag is fixedly provided on one side of the box body 1, and one end of each blowing pipe 5 passes through the box body 1 and is connected to the air bag. A pulse valve is provided on the blowing pipe 5. The pulse valve is started to back-blow the filter bag 3 for dust removal. Start the first motor 9, the first motor 9 drives the convex column 8 to rotate. When the protruding part of the convex column 8 rotates to contact with the top plate 11, as the convex column 8 rotates, the top plate 11 is pushed upward, and the top plate 11 drives the two vibration rods 12 to move upward. The spring 13 is compressed, and the vibration rod 12 drives the vibration frame 14 and the rotating rod 15 to move upward. When the convex column 8 rotates to a state separated from the top plate 11, the top plate 11 drives the vibration rod 12, the vibration frame 14 and the rotating rod 15 to move downward under the action of the spring 13. Such repeated operations make the vibration frame 14 and the rotating rod 15 vibrate up and down continuously. When the first motor 9 is started, the lead screw 7 is driven to rotate through the first transmission belt structure 10, so that the movable frame 6 drives the vibration frame 14 and the rotating rod 15 to move along the two limit rods 19 while vibrating. The rotating rod 15 contacts the bottom of the filter bag 3 while vibrating and moving and continuously knocks the skeleton 4, so that the skeleton 4 drives the filter bag 3 to vibrate, thereby vibrating off the dust at the bottom of the filter bag 3. The rotating rod 15 rotates when in contact with the filter bag 3, thereby reducing friction.
