Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dust removal equipment, in particular to a bag filter. BACKGROUND

[0002] The bag filter is a dry type dust collecting device, which uses woven filter cloth or non-woven felt to make filter bags, and uses the filtering effect of these fiber materials to treat dust-containing gas; when the dust-containing gas enters the bag filter, the dust with large particles and high density is deposited into the ash hopper under the action of gravity; and the gas containing fine dust is trapped when passing through the filter material, thereby realizing the purification treatment of the gas.

[0003] In the prior art, the bag filter generally uses multiple filter bags combined for common filtration, and when the filter bag is damaged, the dust-containing gas will enter the filter bag and the upper clean gas chamber from the damaged part of the filter bag, so that immediate shutdown and replacement are required.

[0005] When the filter bag needs to be replaced due to damage, although the shutdown will prevent the continuous entry of dust-containing gas, due to the inertia of gas flow, dust will still diffuse in the filter box; at this time, directly replacing the filter bag is easy to cause dust leakage to the external environment, increasing the risk of workers exposed to dust; and the method of waiting for dust settlement by standing still will cause long-time filtration failure, affecting the dust removal efficiency.

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] like Figures 1-11 As shown, a bag dust collector, such as Figures 1-3 As shown, it includes a filter box 1 and a bag filter mechanism 2 and a pulse cleaning mechanism 3 arranged in the filter box 1, and the pulse cleaning mechanism 3 is arranged above the bag filter mechanism 2; the bag filter mechanism 2 includes a plurality of filter bags 25 for filtering dust-laden gas; the bag dust collector also includes an isolation mechanism 5 for pushing the damaged filter bags 25 to be compressed and folded along their axial direction; the isolation mechanism 5 includes: a plurality of mounting rings 51, and the plurality of mounting rings 51 are arranged at equal intervals along the axial direction of the inner wall of the filter bag 25; at least one pair of connecting ropes 52, and at least one pair of connecting ropes 52 are arranged along the filter bag 2 5-axis direction is set, one end of the connecting rope 52 passes through multiple mounting rings 51 and is connected to the mounting ring 51 connected to the bottom of the filter bag 25; multiple springs 53, the spring 53 is sleeved on the connecting rope 52, and a spring 53 is set between each adjacent mounting ring 51, and the two ends of the spring 53 are in contact between the adjacent mounting rings 51; and a reeling mechanism 54, the reeling mechanism 54 is set in the filter box 1, and the other end of the connecting rope 52 is connected to the reeling mechanism 54; the reeling mechanism 54 is used to reel in the connecting rope 52 to drive the filter bag 25 to compress.

[0043] It should be noted that the side of the filter bag 25 is the main filtering part, and the part worn between adjacent filter bags 25 is generally the side, so the main damage position of the filter bag 25 is generally the side, so when the filter bag 25 is partially damaged, the filter bag 25 is only compressed and folded on the side to realize the isolation of the inside and outside of the filter bag 25; For use in special environments, it may cause damage to the bottom of the filter bag 25, for example, the dust-containing gas introduced has high-temperature particles, and the high-temperature particles contact the bottom of the filter bag 25 to cause damage to the bottom of the filter bag 25. For this case, a partition can be provided at the bottom of the filter bag 25, and the filter at the bottom of the filter bag 25 is directly discarded. Since the filter area at the bottom of the filter bag 25 is small, the overall filtering effect is not greatly affected, and the bottom filter can be ignored. Adapt to the environment where the bottom of the filter bag 25 is easily damaged; It can be understood that the above-mentioned partition is prior art and is not shown in the figure, and will not be described in detail.

[0044] When the side of the filter bag 25 is damaged, the connecting rope 52 is wound by the winding mechanism 54 to move the bottommost mounting ring 51 in the filter bag 25 upward, and then the plurality of mounting rings 51 are equally spaced close to each other under the action of the spring 53. At this time, the filter bag 25 is folded along its axial direction under the action of force, until the plurality of mounting rings 51 abut against each other, so that the inside and outside of the filter bag 25 are completely isolated, so that the damaged filter bag 25 is completely isolated, so that the dust-containing gas cannot be directly discharged through the damaged filter bag 25, and the normal filtering work of other filter bags 25 is not affected, so that the bag-type dust collector can continue to filter;

[0045] The spring 53 is provided, and when the winding mechanism 54 releases the winding of the connecting rope 52, the compressed spring 53 resets to drive the plurality of mounting rings 51 away from each other, so that the filter bag 25 is completely stretched and opened downward. That is, when the filter bag 25 is in normal use, the filter bag 25 is supported by the elastic force of the spring 53 to be in a normal filtering state, and the normal filtering work is not affected; and when the inside of the filter bag 25 is back-flushed by the pulse cleaning mechanism 3 to clean the dust on the outer wall of the filter bag 25, the spring 53 can provide a certain directional tension when the filter bag 25 is expanded under the action of force. The filter bag 25 can vibrate up and down along its axial direction, improving the effect of cleaning the dust on the outer wall of the filter bag 25.

[0046] As shown in Figures 3-4 The winding mechanism 54 includes a winding disc 541, a guide mechanism 542, and a first driving mechanism 543; the winding disc 541 is arranged in the filter box 1 (as shown in Figure 1 The guide mechanism 542 is arranged on the winding disc 541, one end of the connecting rope 52 is wound on the winding disc 541 through the guide mechanism 542, and the first driving mechanism 543 is arranged in the filter box 1; the first driving mechanism 543 is used to drive the winding disc 541 to rotate to wind the connecting rope 52.

[0047] It should be noted that when the filter bag 25 needs to be compressed and folded, the winding disc 541 is driven to rotate by the first driving mechanism 543, and under the guidance of the guide mechanism 542, the connecting rope 52 is wound, and the bottommost mounting ring 51 in the filter bag 25 is pulled upward through the connecting rope 52, so that the plurality of mounting rings 51 are synchronously close to each other under the cooperation of the spring 53, thereby driving the filter bag 25 to be compressed and folded at equal intervals, until the plurality of mounting rings 51 are stacked and abutted with each other, the filter bag 25 is completely compressed, the inside and outside of the filter bag 25 are isolated, the damaged filter bag 25 is compressed and isolated, and the normal filtering work of the cloth bag dust collector is not affected.

[0048] As shown in Figures 3-6 , the guide mechanism 542 includes a pulley 5421 and a guide block 5422; the pulley 5421 is arranged in the filter box 1 (as shown in Figure 1 ), and the connecting rope 52 abuts against the pulley 5421; the pulley 5421 is used for guiding the movement of the connecting rope 52, and the guide block 5422 is arranged on the winding disc 541; one end of the connecting rope 52 passes through the guide block 5422 and is wound on the winding disc 541; the winding disc 541 is provided with a ring groove 5423, the guide block 5422 is provided with a sliding block, and the sliding block is in sliding connection with the ring groove 5423 and has a cylindrical structure; and the guide block 5422 can rotate along the axis of the cylindrical structure.

[0049] It should be noted that when the winding disc 541 is driven to rotate by the guide mechanism 542, the movement of the connecting rope 52 is first guided by the pulley 5421, and then further guided by the guide block 5422, so that the connecting rope 52 is always wound in the tangential direction of the winding disc 541; that is, when the winding disc 541 rotates, the guide block 5422 slides on the winding disc 541 through the ring groove 5423, and it can be understood that the center of the ring groove 5423 coincides with the axis of the winding disc 541, that is, when the winding disc 541 rotates, the guide block 5422 can maintain the original position, so that the connecting rope 52 is always wound in the tangential direction of the winding disc 541, which can prevent the winding disc 541 from being wound out of position, reduce the mutual intersection of the connecting rope 52 wound on the winding disc 541, facilitate the winding and releasing of the connecting rope 52, and ensure that when a pair of connecting ropes 52 is wound, the upward displacement amount of the pair of connecting ropes 52 is the same as the rotation of the winding disc 541, that is, the filter bag 25 is stably compressed.

[0050] As shown in Figures 4-5 , it can be understood that the specific structure and mounting mode of the first driving mechanism 543 are not limited in the present application, and only one feasible specific implementation scheme is provided below; the first driving mechanism 543 includes a first motor 5431, a worm 5432 and a worm gear 5433; the first motor 5431 is mounted on the filter box 1 (as shown in Figure 1As shown in the figure, the output end of the first motor 5431 is coaxially connected to the worm 5432; the first motor 5431 is used to drive the worm 5432 to rotate along its axis; the worm wheel 5433 is coaxially fixed to the winding disk 541, and the worm 5432 is meshed with the worm wheel 5433.

[0051] It should be noted that when it is necessary to drive the winding disk 541 to rotate in order to reel in the connecting rope 52, the worm 5432 is driven to rotate by the first motor 5431, the worm 5432 is driven to rotate by the worm 5432, and the worm wheel 5433 is driven to rotate by the worm wheel 5433, and the winding disk 541 is driven to rotate along its axis as the center of the circle, thereby achieving the purpose of driving the winding disk 541 to rotate in order to reel in the connecting rope 52; through the setting of the worm 5432 and worm wheel 5433 structure, through its axial self-locking characteristics, the winding state of the connecting rope 52 is ensured, and the stability of use is ensured.

[0052] like Figures 3-4 and Figures 8-11 As shown, the isolation mechanism 5 further includes a control mechanism 55; the control mechanism 55 is used to control the local compression of the filter bag 25; the control mechanism 55 includes a guide shaft 551, a second driving mechanism 554, a plurality of first protrusions 552 and a second protrusion 553; one end of the guide shaft 551 is rotatably connected to the filter box 1 (such as Figure 1 As shown in the figure, a through hole is provided on the mounting ring 51, and the other end of the guide shaft 551 passes through the through holes on the multiple mounting rings 51 and is rotatably connected to the mounting ring 51 connected to the bottom of the filter bag 25, and multiple first protrusions 552 are provided on the guide shaft 551, and the projections of the multiple first protrusions 552 along the axial direction of the guide shaft 551 overlap, and a second protrusion 553 is provided in the through hole on each mounting ring 51, and the multiple second protrusions 553 are arranged at equal intervals along the circumference of the guide shaft 551, and the projections of the multiple second protrusions 553 along the axial direction of the guide shaft 551 form a circular ring structure; the second driving mechanism 554 is provided in the filter box 1, and the second driving mechanism 554 is used to drive the guide shaft 551 to rotate along its axis.

[0053] It should be noted that, through the setting of the control mechanism 55, when a local position of a filter bag 25 is damaged, the damaged position of the filter bag 25 is driven by the control mechanism 55 to be compressed upward, thereby sealing the damaged position, so that the dust-laden gas cannot enter the filter bag 25 through the damaged position; and the area below the damaged position on the filter bag 25 is still in a normal expanded state, that is, at this time, the area below the damaged position of the filter bag 25 can still perform normal filtering work; thereby improving the utilization rate of the filter bag 25, so that when local damage occurs, the impact on the overall filtering effect can be minimized, thereby ensuring the filtering efficiency;

[0054] Specifically, when the entire structure of the filter bag 25 needs to be completely compressed and folded, the second driving mechanism 554 drives the guide shaft 551 to rotate, so that the multiple first protrusions 552 on the guide shaft 551 are all misaligned with the multiple second protrusions 553 on the mounting rings 51, that is, the compression and folding of the entire filter bag 25 by pulling the connecting rope 52 is not affected;

[0055] When the side of the filter bag 25 is partially damaged, the guide shaft 551 is driven to rotate by the second driving mechanism 554, so that one of the first protrusions 552 and the second protrusion 553 on the mounting ring 51 near the top are staggered along the axis projection of the guide shaft 551. When the connecting rope 52 is pulled to move, the connecting rope 52 drives the mounting ring 51 at the bottom end of the filter bag 25 to move upward, thereby driving the first protrusion 552 on the guide shaft 551 to move upward. Since one of the first protrusions 552 and the second protrusion 553 are staggered, the first protrusion 552 can push the second protrusion 553 upward, that is, push the mounting ring 51 at this position to move upward until the mounting ring 51 contacts the top of the filter bag 25. The area of ​​the filter bag 25 below the mounting ring 51 is still in the expanded state, thereby achieving compression and isolation of the locally damaged position without affecting the filtering work at other positions on the filter bag 25.

[0056] In the process of driving the guide shaft 551 to rotate and drive the first protrusion 552 to rotate, that is, through the position setting of the first protrusion 552 and the second protrusion 553, only one first protrusion 552 can be completely staggered with the second protrusion 553 at a time (such as Figures 7-11 As shown in FIG. 1 , when the top first protrusion 552 on the guide shaft 551 is completely interlaced with the second protrusion 553 on the top mounting ring 51, the other second protrusions 553 are completely staggered with the first protrusion 552 in the axial projection of the first protrusion 552, that is, the filter bag 25 and the top area of ​​the filter bag 25 on the top mounting ring 51 can be compressed and folded; when the second first protrusion 552 from the top to the bottom on the guide shaft 551 is completely interlaced with the second second protrusion 553 on the top mounting ring 51 , the other second protrusions 553 are completely offset from the first protrusions 552 in the axial projection of the first protrusions 552, that is, the filter bag 25 above the second mounting ring 51 and the top area of ​​the filter bag 25 can be compressed and folded at this time; in this way, the guide shaft 551 is driven to rotate, and the compressed and folded area of ​​the filter bag 25 can be gradually increased to adapt to the compression and isolation work of different damaged positions; it can be understood that the above-mentioned descriptions such as above and from top to bottom mean that the position close to the top of the filter box 1 is above, and the position close to the bottom of the filter box 1 is below.

[0057] like Figures 3-4 and Figure 7As shown, it can be understood that the present application does not limit the local structure and installation method of the second driving mechanism 554. The following only provides a feasible implementation scheme; the second driving mechanism 554 includes a belt 5542, a second mounting plate 5543, a second motor 5544, a second rotating wheel 5545 and two first rotating wheels 5541; the control mechanism 55 includes a pair of guide shafts 551, the two first rotating wheels 5541 are coaxially arranged on the pair of guide shafts 551, the belt 5542 is tightened on the pair of guide shafts 551, and the second mounting plate 5543 is tightened on the second motor 5544. 43 is arranged in the filter box 1, the second motor 5544 is installed on the second mounting plate 5543, and the output end of the second motor 5544 is provided with a second rotary wheel 5545, and the second rotary wheel 5545 and a pair of first rotary wheels 5541 are tensioned on the same belt 5542; the second motor 5544 is used to drive the second rotary wheel 5545 to rotate, so as to drive the belt 5542 to transmit; a guide wheel 5546 is rotatably connected in the filter box 1, and the guide wheel 5546 is in conflict with the belt 5542; the guide wheel 5546 is used to provide guidance for the transmission of the belt 5542.

[0058] It should be noted that the second motor 5544 drives the second rotating wheel 5545 to rotate, and under the guidance of the guide wheel 5546 and the cooperation of the belt 5542, the two first rotating wheels 5541 are driven to rotate synchronously, and then the two guide shafts 551 are driven to rotate synchronously, so that when the filter bag 25 is compressed and folded, the filter bag 25 can be compressed smoothly, reducing the problem of skewness caused by uneven force on the filter bag 25, which affects the compression isolation effect.

[0059] like Figures 1-2 As shown, it can be understood that the present application does not limit the specific structure and installation method of the bag filter mechanism 2. The following only provides a feasible specific implementation scheme; the bag filter mechanism 2 also includes an inlet pipe 21 and an outlet pipe 22 arranged on the filter box 1; a first mounting plate 23 is provided in the filter box 1, and a plurality of filter bags 25 are arranged on the first mounting plate 23.

The inlet pipe 21 is connected to the chamber located below, and the outlet pipe 22 is connected to the chamber located above; a plurality of venturi tubes 2 are provided on the first mounting plate 23. 4.

The protective cover 4 protects the reeling mechanism 54 to reduce interference from the external environment on the operation of the reeling mechanism 54.

[0060] It should be noted that when the cloth bag dust collector is used, the dust-containing gas is introduced into the filter box 1 through the inlet pipe 21, and after being filtered by the plurality of filter bags 25, the dust-containing gas moves upward through the venturi 24 and is then discharged through the outlet pipe 22, thereby realizing complete filtration work.

[0061] As shown in Figures 1-2 It can be understood that the specific structure and mounting mode of the pulse cleaning mechanism 3 are not limited in the present application, and only one feasible specific implementation scheme is provided below; the pulse cleaning mechanism 3 comprises a spray pipe 31 and a plurality of spray heads 32; the spray pipe 31 is arranged in the upper chamber in the filter box 1, the plurality of spray heads 32 are in communication with the spray pipe 31, and the plurality of spray heads 32 are arranged above the venturi 24.

[0062] It should be noted that when the filter bag 25 needs to be cleaned, the high-pressure gas is introduced into the spray pipe 31, so that the gas sprayed by the spray head 32 is introduced into the filter bag 25 through the venturi 24, so that the air pressure in the filter bag 25 is instantaneously increased, thereby blowing off the dust attached to the outer wall of the filter bag 25, achieving the purpose of dust removal, and ensuring the long-term filtering effect of the filter bag 25; and the arrangement of the isolation mechanism 5 does not affect the normal use of the pulse cleaning mechanism 3, and can make the filter bag 25 vibrate up and down when the pulse cleaning mechanism 3 is working, thereby improving the dust removal effect.
