Description

Technical Field

[0001] The present invention relates to the technical field related to bag dust removal, and in particular to a split-type bag dust removal device. Background Art

[0002] A bag filter is a highly efficient dry dust collector. It relies on filter bags made of fibrous filter media, primarily through the dust layer that forms on the bag's surface to purify the air. Its dust removal efficiency can exceed 99% for nearly all dust particles in general industry.

[0003] The patent document "Filter Bag Dust Collector" with Chinese application number CN202223439469.4 discloses a filter bag type dust collector, which uses a partition plate, a filter bag mounting seat, a filter bag connecting seat, a filter bag body and a cleaning component to cooperate with each other to separate the dust removal chamber and the exhaust chamber in the shell by using the partition plate, and under the action of the filter bag mounting seat, the filter bag body on the filter bag connecting seat filters the air in the dust removal chamber, and the cleaning component supports the filter bag body in the dust removal state to ensure the dust removal efficiency of the filter bag body, and the cleaning component oscillates the filter bag body in the cleaning state to make the dust attached to the outer surface of the filter bag body fall off from the shell, which can achieve the effect of vibrating and cleaning the filter bag body, and avoid the dust deposited on the filter bag body reducing the filtration efficiency of the filter bag body.

[0004] However, the above patent still has the following shortcomings: when the filter bag is driven to vibrate, the dust attached to its surface will fall down, and the incoming air flow will flow upward, the air flow will disperse the accumulated dust, so that the dust is re-mixed into the air, which is not conducive to real-time cleaning of the filter bag. The filter bag needs to be stopped for cleaning, and the dust will be discharged through the lower end of the ash hopper. When cleaning the dust inside the ash hopper, some dust will also fly into the air. The large amount of dust in the air not only affects the vision, but also is not conducive to the health of the operator. Therefore, it is necessary to design a split bag dust removal device.

DETAILED DESCRIPTION

[0020] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0021] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0022] like Figure 1-6 As shown, a split-type bag dust removal device comprises: a barrel body 2 with an air inlet 1 on the top, a partition 3 fixedly arranged at the middle of the inner side of the barrel body 2, and a first dust bag 4 with both ends open, a ventilation window 5 is provided through the middle of the partition 3, a dust collecting unit matching the ventilation window 5 is detachably mounted on the bottom of the partition 3, an elastic sealing connection unit mounted on the ventilation window 5 is provided on the upper surface of the partition 3, the upper end of the first dust bag 4 is mounted on the lower end of the air inlet 1 through a first mounting mechanism, and the lower end of the first dust bag 4 is connected to the elastic sealing connection unit through a second mounting mechanism; The dust collecting unit includes a second dust removal bag 6 with its open end facing upward, the elastic sealing connection unit includes a first ring piece 7 connected to a second mounting mechanism, the partition 3 is equipped with a vibration unit for driving the first ring piece 7 to vibrate up and down, a pair of air outlets 8 are provided on the barrel body 2, which are respectively located above and below the partition 3, and a pair of openable and closable doors 9 are provided on the barrel body 2, which are respectively located above and below the partition 3.

[0023] In the above technical solution, the air flow enters the first dust bag 4 from the air inlet 1, and then enters the second dust bag 6 through the ventilation window 5. The dust will be blocked by the first dust bag 4 and the second dust bag 6. The air will pass through the first dust bag 4 and the second dust bag 6, and then be discharged through the air outlet 8. The vibration unit can drive the first ring piece 7 to shake up and down, thereby driving the first dust bag 4 to shake, which can shake off the dust on the inner wall of the first dust bag 4. The shaken dust will follow the air flow through the ventilation window 5 and fall into the second dust bag 6 for collection, so that the first dust bag 4 always maintains good filtering performance, and the dust collection function of the first dust bag 4 will not be affected by dust accumulation; The second dust bag 6 plays the role of collecting dust throughout the filtering process, and can also play the role of filtering dust in the second dust bag 6, but its filtering effect gradually decreases as the dust inside accumulates, which is conducive to cleaning the accumulated dust; The first dust bag 4 and the second dust bag 6 can be replaced by opening the door 9. The first dust bag 4 is replaced less frequently, while the second dust bag 6 is replaced more frequently. Since the second dust bag 6 collects dust, the second dust bag 6 needs to be replaced regularly. There is no need to additionally fill the accumulated dust. The second dust bag 6 can be completely removed, which can also reduce the amount of dust that is re-entrained into the air during replacement. According to actual use requirements, an intake fan can be installed on the air inlet 1 to assist air intake, and an exhaust fan can be installed on the air outlet 8 to assist exhaust.

[0024] In a preferred embodiment of the present invention, the dust collecting unit also includes a first tubular member 10 whose upper end is fitted on the lower surface of the partition 3 and is sleeved on the outside of the ventilation window 5, a second annular piece 11 rotatably connected to the lower end of the first tubular member 10 through a first hinge shaft, and a locking mechanism mounted on the side of the second annular piece 11 away from the first hinge shaft and detachably connected to the partition 3. The edge of the second annular piece 11 is also equipped with a plurality of auxiliary mechanisms distributed at intervals along the circumferential direction for clamping the edge of the open end of the second dust bag 6.

[0025] In the above technical solution, when replacing the second dust bag 6, the locking mechanism is first opened, at which time the second ring piece 11 can rotate around the first hinge axis, and then several auxiliary mechanisms are opened to loosen the open edge of the second dust bag 6, so that the second dust bag 6 filled with dust can be removed; Then pass the open end of the new second dust bag 6 through the inner side of the second ring piece 11 and turn it outward, and use an auxiliary mechanism to clamp the outward-turned end part of the second ring piece 11. The function of the auxiliary mechanism is to prevent the end of the second dust bag 6 from separating from the second ring piece 11 when the second ring piece 11 rotates upward. Since the open end of the second dust bag 6 needs to be clamped by the second ring piece 11 and the lower end of the first tubular member 10, the auxiliary mechanism is conducive to replacing the second dust bag 6 and improves the efficiency of replacement.

[0026] In a preferred embodiment of the present invention, the auxiliary mechanism includes a first clamping arm 12 fixedly mounted on the second ring piece 11 at one end, a second clamping arm 13 hinged to the middle of the first clamping arm 12 through a second hinge shaft in the middle, and a torsion spring mounted on the second hinge shaft and with its two ends respectively in contact with the end portions of the first clamping arm 12 and the second clamping arm 13 away from the axis of the second ring piece 11.

[0027] In the above technical solution, by pinching the ends of the first clamping arm 12 and the second clamping arm 13 away from the axis of the second ring piece 11, the end edge of the second dust bag 6 can be loosened; after loosening, the torsion spring will push the first clamping arm 12 and the second clamping arm 13 to clamp the end edge of the second dust bag 6.

[0028] In a preferred embodiment of the present invention, the locking mechanism includes a threaded rod 14 assembled on the partition 3 through a hinged seat and a butterfly nut 15 threadedly assembled on the threaded rod 14 and capable of abutting against the lower surface of the second ring piece 11. A notch portion matching the threaded rod 14 is provided on the side of the second ring piece 11 away from the first hinge axis.

[0029] In the above technical solution, after the end of the new second dust bag 6 is clamped by the auxiliary mechanism, the second ring piece 11 is rotated upward so that the threaded rod 14 enters the notch, and the butterfly nut 15 is continuously rotated so that it tightly contacts the lower surface of the second ring piece 11, so that the second ring piece 11 and the lower end of the first tubular member 10 tightly clamp the open end of the second dust bag 6.

[0030] In a preferred embodiment of the present invention, the elastic sealing connection unit further includes a rubber bellows 16 whose lower end is fixedly connected to the edge of the ventilation window 5 and a plurality of vertical guide rods 17 fixedly assembled on the partition 3, and a limit member 18 is provided at the top of each guide rod 17; The upper end of the rubber bellows 16 is fixedly connected to the inner edge of the first ring piece 7 , and the first ring piece 7 is slidably sleeved on a plurality of guide rods 17 .

[0031] In the above technical solution, the rubber bellows 16 can ensure the sealing between the first ring piece 7 and the partition plate 3 during the process of moving up and down.

[0032] In a preferred embodiment of the present invention, the vibration unit includes an annular seat 19 coaxially mounted on the lower surface of the first ring piece 7, a rotating ring piece 20 coaxially arranged with the annular seat 19 and slidably connected to the partition 3 with its own axis as the rotation axis, an annular rack 21 coaxially mounted on the rotating ring piece 20, and a motor 22 mounted on the partition 3 via a mounting frame and transmission-connected to the annular rack 21; At least one guide rod 17 is equipped with a spring 23 whose two ends respectively contact the limit member 18 and the partition 3. The lower end of the annular seat 19 is provided with at least one protrusion 24, and the rotating ring piece 20 is provided with at least one pulley 25 that is in sliding contact with the lower end of the annular seat 19.

[0033] In the above technical solution, the motor 22 can drive the rotating ring piece 20 to rotate through the annular rack 21, and the rotating ring piece 20 drives the pulley 25 to rotate. When the pulley 25 contacts the protrusion 24, it will push the first ring piece 7 to slide upward on the guide rod 17; when the pulley 25 passes the protrusion 24, the spring 23 will push the first ring to move downward on the guide rod 17, so that the lower end of the annular seat 19 contacts the pulley 25 again, thereby driving the first dust bag 4 to shake continuously.

[0034] In a preferred embodiment of the present invention, the second mounting mechanism includes a third ring piece 26 capable of cooperating with the first ring piece 7 to clamp the lower end of the first dust removal bag 4, a plurality of first wedge-shaped members 27 evenly distributed along the circumference of the third ring piece 26 and fixedly connected to the third ring piece 26, a plurality of second wedge-shaped members 28 corresponding one-to-one to the plurality of first wedge-shaped members 27 and all mounted on the lower surface of the first ring piece 7, a first connecting seat fixedly mounted on the partition plate 3, a second connecting seat fixedly mounted on the third ring piece 26, and a connecting bolt 29 for connecting the first connecting seat and the second connecting seat; The first ring piece 7 is provided with a plurality of arc-shaped through grooves 30 that match the corresponding first wedge-shaped pieces 27 .

[0035] In the above technical solution, when the first dust bag 4 needs to be replaced, the connecting bolt 29 is removed and the third ring piece 26 is rotated to drive the second connecting seat to rotate away from the first connecting seat, which will also drive the first wedge piece 27 to separate from the corresponding second wedge piece 28, and the third ring piece 26 is moved upward, and the first wedge piece 27 is moved out of the corresponding arc-shaped groove 30; then the lower end of the new first dust bag 4 is clamped by the third ring piece 26 and the first ring piece 7, and the third ring piece 26 is rotated to increase the contact area between the first wedge piece 27 and the second wedge piece 28. As the contact area between the two increases, the smaller the distance between the third ring piece 26 and the first ring piece 7, the greater the clamping force applied to the lower end of the first dust bag 4, and then the first connecting seat and the second connecting seat are connected together by the connecting bolt 29 to prevent the third ring piece 26 from rotating in the opposite direction and loosening.

[0036] In a preferred embodiment of the present invention, the first mounting mechanism includes a vertical second tubular member 31 whose upper end is fixedly connected to the lower end of the air inlet 1, a fourth ring piece 32 spaced apart and sleeved on the outside of the second tubular member 31, and a limiting ring piece 33 coaxially fixedly assembled on the lower end of the second tubular member 31; The top end of the second tubular member 31 is coaxially protruding outward with a mounting flange, on which are mounted a plurality of threaded seats 34 evenly distributed along the circumferential direction, each threaded seat 34 being threadedly connected with a vertical mounting bolt 35 whose lower end can be pressed onto the fourth ring piece 32.

[0037] In the above technical solution, when the first dust bag 4 needs to be replaced, the mounting bolt 35 is loosened so that the head of the mounting bolt 35 moves upward. At this time, the fourth ring piece 32 can move upward to loosen the upper end of the first dust bag 4; the upper end of the new first dust bag 4 is clamped with the fourth ring piece 32 and the limiting ring piece 33, and the mounting bolt 35 is continuously tightened so that it is tightly pressed on the fourth ring piece 32, thereby increasing the pressure applied by the fourth ring piece 32 to the upper end of the first dust bag 4 and increasing the clamping force.

[0038] In a preferred embodiment of the present invention, an annular protrusion matching the mounting bolt 35 is protruded from the upper surface of the fourth ring piece 32 , and the head of the mounting bolt 35 is located inside the annular protrusion.

[0039] In the above technical solution, the annular protrusion plays an auxiliary positioning role to prevent the fourth ring piece 32 from sliding and tilting.

[0040] In a preferred embodiment of the present invention, a vertical connecting shaft is assembled on the partition 3 through a shaft seat, a gear engaged with the annular rack 21 is fixed on the connecting shaft, and the output shaft of the motor 22 is connected to the connecting shaft through a pair of meshing bevel teeth.

[0041] In the above technical solution, the motor 22 drives the connecting shaft to rotate through a pair of bevel gears, and then drives the annular rack 21 to rotate through the gear, thereby driving the rotating ring piece 20 to rotate.

[0042] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.
