Detailed Description
The drawings are for illustrative purposes only and are not to be construed as limiting the present patent; for the purpose of better illustrating the present embodiment, certain elements of the drawings may be omitted, enlarged or reduced and do not represent the actual product dimensions.
It will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The technical scheme of the invention is further described below with reference to the accompanying drawings and examples.
The filter bag dust collector as shown in the attached drawing comprises a shell 1, wherein a filter bag 2 extending along the vertical direction is arranged in the shell 1, an inner sleeve assembly 3 and an outer sleeve assembly 4 which can move along the vertical direction are sleeved on the inner side and the outer side of the filter bag 2 respectively, a dust removing cavity is formed between the inner sleeve assembly 3 and the outer sleeve assembly 4, the inner sleeve assembly 3 and the outer sleeve assembly 4 can clamp or loosen the filter bag 2 from the edge of the dust removing cavity, a beating assembly 5 acting on the dust removing cavity is arranged on the outer sleeve assembly 4, and the beating assembly 5 has a stop state and an operating state;
during the process that the inner sleeve assembly 3 and the outer sleeve assembly 4 move along the vertical direction, the inner sleeve assembly 3 and the outer sleeve assembly 4 loosen the filter bag 2, and the beating assembly 5 is in a stop state;
when the beating assembly 5 is in an operating state, the inner sleeve assembly 3 and the outer sleeve assembly 4 clamp the filter bag 2 from the edge of the ash cleaning cavity, so that the ash cleaning cavity is isolated from the outside.
Specifically, in this embodiment, the filter bag 2 is divided into upper and lower sections for ash removal.
When the inner sleeve component 3 and the outer sleeve component 4 are used for ash removal of the upper section of the filter bag 2, the upper section of the filter bag 2 is located in the ash removal cavity, the beating component 5 is in an operating state, the beating component 5 drives the part of the filter bag 2 located in the ash removal cavity to shake, so that dust on the appearance of the part falls off, and in order to prevent the dust falling off from the appearance of the part from drifting into gas again, the inner sleeve component 3 and the outer sleeve component 4 clamp the filter bag 2 from the edge of the ash removal cavity, so that the ash removal cavity is isolated from the outside. In addition, after the inner sleeve component 3 and the outer sleeve component 4 clamp the filter bag 2 from the edge of the ash cleaning cavity, the shake of the upper section of the filter bag 2 can not be transferred to the lower section along the filter bag 2, so that the lower section of the filter bag 2 can still work normally, and dust on the outer surface of the lower section of the filter bag 2 can not fly into the air again, thereby causing secondary pollution.
When the inner sleeve assembly 3 and the outer sleeve assembly 4 need to be moved from the upper section of the filter bag 2 to the lower section of the filter bag 2, the inner sleeve assembly 3 and the outer sleeve assembly 4 loosen the filter bag 2, the ash cleaning cavity at the moment is communicated with the outside, and the beating assembly 5 is in a stop state in order to prevent the beating assembly 5 from driving the filter bag 2 to shake in the moving process of the inner sleeve assembly 3 and the outer sleeve assembly 4.
Preferably, the inner sleeve assembly 3 comprises a supporting seat 31, the bottom end of the supporting seat 31 is integrally connected with an inner bottom ring 32, the top of the supporting seat 31 is slidably connected with a moving frame 33, the moving frame 33 is integrally connected with an inner top ring 34, and an elastic cylinder 35 is connected between the inner bottom ring 32 and the inner top ring 34. It will be appreciated that the inner lower and upper rings 34 are not only capable of providing an anti-collapse function to the filter bag 2. In addition, in certain specific situations, such as where the gas to be filtered contains dust and moisture, dust tends to form dust agglomerations on the exterior of the filter bag 2 under the action of the moisture, and the dust agglomerations formed are difficult to remove by beating. For this reason, the outer diameters of the inner bottom ring 32 and the inner top ring 34 of the present embodiment are slightly larger than the inner diameter of the filter bag 2, so that during the process that any part of the filter bag 2 slides over the inner bottom ring 32 or the inner top ring 34, the part is changed in diameter, so that dust agglomerates on the part are broken, and the cleaning is facilitated by the subsequent beating mode. This design is not only advantageous for preventing the filter bag 2 from collapsing, but also for improving the cleaning efficiency of dust agglomerations.
The outer sleeve assembly 4 comprises an outer bottom ring 41 and an outer top ring 42, wherein the outer bottom ring 41 is positioned below the inner bottom ring 32, the projection parts of the outer bottom ring 41 and the inner bottom ring 32 along the vertical direction are overlapped, the outer top ring 42 is positioned above the inner top ring 34, the projection parts of the outer top ring 42 and the inner top ring 34 along the vertical direction are overlapped, and a supporting cylinder 43 is connected between the outer bottom ring 41 and the outer top ring 42.
The supporting seat 31 is connected with a lifting mechanism 6, and the lifting mechanism 6 can drive the supporting seat 31 to move along the vertical direction.
Specifically, the upgrade mechanism can drive the inner sleeve assembly 3 to move in the vertical direction through the supporting seat 31, and since the outer bottom ring 41 is located below the inner bottom ring 32 and the projection portions of the outer bottom ring 41 and the inner bottom ring 32 in the vertical direction coincide, the outer top ring 42 is located above the inner top ring 34 and the projection portions of the outer top ring 42 and the inner top ring 34 in the vertical direction coincide, so that the outer sleeve assembly 4 moves synchronously with the inner sleeve assembly 3.
The movable frame 33 is connected with a lifting mechanism 7, and the lifting mechanism 7 can drive the inner top ring 34 to be close to or far from the inner bottom ring 32 along the vertical direction through the movable frame 33. If the filter bag 2 needs to be loosened from the edge of the ash removing cavity by the inner sleeve assembly 3 and the outer sleeve assembly 4, the lifting mechanism 7 drives the inner top ring 34 to be close to the inner bottom ring 32 along the vertical direction; if it is desired to clamp the filter bag 2 from the edge of the ash removal chamber with the inner sleeve assembly 3 and the outer sleeve assembly 4, the lifting mechanism 7 drives the inner top ring 34 vertically away from the inner bottom ring 32, thereby firmly holding the inner top ring 34 against the outer top ring 42 and the inner bottom ring 32 against the outer bottom ring 41.
It can be understood that when the inner top ring 34 does not abut against the outer top ring 42, the outer bottom ring 41 presses the filter bag between the outer bottom ring 41 and the inner bottom ring 32 under the action of gravity, so that the filter bag 2 is prevented from sliding between the outer bottom ring 41 and the inner bottom ring 32, in order to solve the problem, the inner top ring 34 of the present embodiment is provided with a first permanent magnet 341, and the outer top ring 42 is provided with a second permanent magnet 421 which is mutually exclusive to the first permanent magnet 341, wherein the first permanent magnet 341 and the second permanent magnet 421 can increase the gap between the inner bottom ring 32 and the outer bottom ring 41, so that the filter bag 2 can slide more smoothly between the outer bottom ring 41 and the inner bottom ring 32.
Preferably, the lifting mechanism 6 comprises a guide rod 61 extending along the vertical direction, a threaded rod 62, a worm wheel 63 integrally sleeved on the outer side of the threaded rod 62, a worm 64 meshed with the worm wheel 63, and a motor 65 in transmission connection with the worm 64, the supporting seat 31 is in sliding connection with the guide rod 61, the supporting seat 31 is in threaded connection with the threaded rod 62, and the threaded rod 62 is in rotational connection with the casing 1. Specifically, the motor 65 rotates the worm wheel 63 through the worm 64, thereby rotating the threaded rod 62, and thus the support seat 31 threadedly coupled with the threaded rod 62 moves along the guide rod 61.
Preferably, the lifting mechanism 7 includes a lever 71 extending in a vertical direction and rotationally connected with the housing 1, a swing arm 72 integrally connected with the lever 71, and a first electromagnet 73 in transmission connection with the swing arm 72, wherein a plurality of protruding collision parts 711 are uniformly distributed on the side of the lever 71 along the circumferential direction, a through hole for the lever 71 to pass through is formed in the supporting seat 31, a first mounting hole communicated with the through hole is formed in the through hole, a lifting block 74 is slidably connected in the first mounting hole, one end of the lifting block 74 extends into the through hole, and an inclined part acting on the bottom end of the movable frame 33 is formed at the other end of the lifting block 74. Specifically, when the inner top ring 34 needs to be separated from the inner bottom ring 32 in the vertical direction, the first electromagnet 73 drives the operating lever 71 to rotate through the swing arm 72, so that the abutting portion 711 of the operating lever 71 abuts against the lifting block 74 and pushes the lifting block 74 to move in a direction away from the axis line of the avoidance hole, and then the inner top ring 34 follows the moving frame 33 to be separated from the inner bottom ring 32 in the vertical direction under the action of the inclined portion of the lifting block 74. It can be appreciated that, since the elastic tube 35 is connected between the inner bottom ring 32 and the inner top ring 34, when the first electromagnet 73 drives the operating lever 71 to rotate, the inner top ring 34 will vertically approach the inner bottom ring 32 under the action of the elastic tube 35 and the gravity of the inner top ring after the abutting portion 711 of the operating lever 71 is separated from the lifting block 74. As one example, the elastic tube 35 is made of elastic rubber.
Preferably, a plurality of second mounting holes are uniformly distributed on the side wall of the supporting cylinder 43 along the circumferential direction, a transmission rod 51 is hinged in the second mounting holes, a beating plate 52 is connected to one end of the transmission rod 51 located on the inner side of the supporting cylinder 43, an air receiving plate 53 is connected to one end of the transmission rod 51 located on the outer side of the supporting cylinder 43, and a first elastic piece 54 and a sealing sleeve 55 are connected between the transmission rod 51 and the supporting cylinder 43. The air receiving plate 53 can drive the transmission rod 51 to swing under the action of wind force, so that the beating plate 52 on the transmission rod 51 continuously beats the part of the filter bag 2 in the ash cleaning cavity. It will be appreciated that the housing 1 of the present embodiment ceases to provide air intake during movement of the inner and outer sleeve assemblies 3, 4 in the vertical direction, which, although results in a brief downtime, requires significantly less time for movement of the inner and outer sleeve assemblies 3, 4 than for tapping the filter bag 2 to remove ash, and therefore the continuity of operation of the present embodiment is still greater than with existing filter bag dust collectors. After the inner sleeve assembly 3 and the outer sleeve assembly 4 are moved to the designated positions, the inner top ring 34 moves upward, so that the inner top ring 34 is firmly abutted against the outer top ring 42, and the inner bottom ring 32 is firmly abutted against the outer bottom ring 41, so that the inner top ring 34 and the outer top ring 42, and the inner bottom ring 32 and the outer bottom ring 41 cooperate to clamp the filter bag 2 from the edge of the ash removal cavity, the ash removal cavity is isolated from the outside, and then the shell 1 can be re-air-taken to continue filtering the gas.
Preferably, the inside of the shell 1 is sequentially provided with an exhaust cavity 1a and an air inlet cavity 1b from top to bottom, an air vent is communicated between the exhaust cavity 1a and the air inlet cavity 1b, an ash discharge hole 1c is formed in the position of the bottom end of the shell 1, which is aligned with the air vent, an ash collecting hopper 81 is arranged in the ash discharge hole 1c, a gap is reserved between the inner wall of the ash discharge hole 1c and the outer wall of the ash collecting hopper 81, the top end of the filter bag 2 is integrally connected with the air vent, the bottom end of the filter bag 2 is integrally connected with the ash collecting hopper 81, and an ash discharge valve 82 is communicated with the bottom end of the ash collecting hopper 81. The ash discharge valve 82 comprises a valve body 821, an ash discharge channel communicated with the ash collection hopper 81 is penetrated on the valve body 821, a valve plate 822 capable of closing or opening the ash discharge channel is connected in a sliding manner, and a second electromagnet 823 is connected to the valve plate 822 in a transmission manner.
It can be appreciated that in order to avoid excessive dust accumulation in the ash removal cavity, which affects the ash removal efficiency, the ash removal cavity needs to be emptied in time. For this reason, the top ends of the inner bottom ring 32 and the outer bottom ring 41 of the present embodiment are both provided with an ash collecting cavity 9a communicated with the ash removing cavity, the bottom end of the ash collecting cavity 9a is communicated with an ash discharging channel, a blocking ring 91 capable of closing or opening the ash discharging channel is arranged in the ash discharging channel, the top end of the blocking ring 91 is inclined, the bottom end of the blocking ring 91 is connected with a second elastic member 92, the blocking ring 91 keeps a trend of closing the ash discharging channel by the second elastic member 92, the inner side wall of the inner bottom ring 32 and the outer side wall of the outer bottom ring 41 are both provided with third mounting holes, a deflector rod 93 is hinged in the third mounting holes, one end of the deflector rod 93 is in butt joint with the blocking ring 91, a trigger member 94 adapted to the deflector rod 93 is arranged in the ash discharging hole 1c, and the trigger member 94 can drive the deflector rod 93 to rotate so that the deflector rod 93 drives the blocking ring 91 to open the ash discharging channel.
Specifically, in this embodiment, the filter bag 2 is divided into upper and lower sections for ash removal.
When the inner sleeve assembly 3 and the outer sleeve assembly 4 ash the upper section of the filter bag 2, the trigger 94 is not in contact with the deflector rod 93, the blocking ring 91 closes the ash discharge channel, and dust cleaned from the upper section of the filter bag 2 is stored in the ash collection chamber 9a, not blown away by the air flow flowing through the lower section of the filter bag 2.
When the inner sleeve assembly 3 and the outer sleeve assembly 4 are used for ash removal on the lower section of the filter bag 2, the trigger piece 94 is propped against the deflector rod 93, so that the blocking ring 91 is driven to open the ash discharge channel by stirring, dust cleaned from the upper section of the filter bag 2 and the original dust in the ash collecting cavity 9a can be discharged through the ash discharge channel, and in this state, because the inner bottom ring 32 and the outer bottom ring 41 are far away from the upper section of the filter bag 2, the influence of air flow flowing through the upper section of the filter bag 2 on the dust falling through the ash discharge channel is small, and the dust falling through the ash discharge channel cannot be blown away. As can be appreciated, dust falling through the dust discharge channel of the inner bottom ring 32 is temporarily stored in the dust collection hopper 81, and equipment maintenance personnel can empty the dust in the dust collection hopper 81 by periodically opening the dust discharge valve 82; the dust falling through the dust discharge passage of the outer bottom ring 41 then flows away through the gap between the inner wall of the dust discharge hole 1c and the outer wall of the dust hopper 81.
