Description

Technical Field

[0001] This application relates to the field of baghouse dust collector technology, and specifically to a baghouse dust collector. Background Technology

[0002] A dust collector, or dust removal equipment, is a device that separates dust from dust-laden gas. A baghouse dust collector is a dry dust collection device suitable for capturing fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter the dust-laden gas. When dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle due to gravity and fall into the ash hopper. Gas containing finer dust particles is purified by trapping the dust as it passes through the filter media, hence its widespread use.

[0003] In practical applications, baghouse dust collectors require regular replacement of the filter bags. However, the existing baghouse dust collectors have relatively complex operations for installing and removing the filter bags, resulting in low efficiency in replacing the filter bags and affecting the use of the baghouse dust collectors. Summary of the Invention

[0004] The purpose of this application is to overcome the problem that the installation and removal of filter bags in existing baghouse dust collectors are relatively complicated, resulting in low efficiency in replacing filter bags and affecting the use of baghouse dust collectors.

[0005] To achieve the above objectives, this application provides a bag filter dust collector, which includes: The dust collector body has an internal main chamber; The mounting plate is installed in the main body chamber. The mounting plate can divide the main body chamber into an air inlet chamber and an air outlet chamber along the first direction. The mounting plate has an installation space and multiple mounting holes extending along the first direction. The multiple mounting holes connect the air inlet chamber, the installation space and the air outlet chamber in sequence. Multiple bag assemblies correspond one-to-one with multiple mounting holes. Each bag assembly includes a bag and a bag frame installed inside the bag. The bag is installed in the corresponding mounting hole, and the opening end of the bag is located in the air outlet chamber. Multiple mounting components correspond one-to-one with multiple mounting holes. Each mounting component includes two mounting units disposed opposite each other on both sides of the corresponding mounting hole along a second direction. The two mounting units are movably disposed along the second direction so as to press against the cloth bag located in the mounting hole when they come close to each other. The first direction and the second direction are set at an angle.

[0006] In an embodiment of this application, the mounting unit includes a top block and a movable rod extending in a second direction. The movable rod is movably disposed in the second direction, and the top block is mounted on one end of the movable rod near the mounting hole.

[0007] In embodiments of this application, each mounting component further includes a limiting member mounted on the mounting plate, which can limit the two top blocks when the two mounting units are pressed against the cloth bag.

[0008] In embodiments of this application, the limiting member includes: The rotating part is arranged in a ring shape and sleeved on the corresponding mounting hole. The rotating part is rotatably mounted on the side of the mounting plate near the air outlet chamber around the axis in the first direction. Two abutting rods, one end of which is connected to the bottom end of the rotating part, the two abutting rods extend along a first direction and are arranged opposite each other along a diameter of the rotating part; The mounting plate has an arc-shaped hole corresponding to the rotation trajectory of the rotating part, so that two abutment rods can extend into the mounting space and rotate together with the rotating part. When the two mounting units press against the cloth bag, the two abutment rods can rotate to the side of the top block away from the cloth bag.

[0009] In embodiments of this application, each mounting unit further includes an elastic element disposed on the side of the top block near the cloth bag.

[0010] In embodiments of this application, each installation unit further includes a mounting bracket disposed within the installation space, the mounting bracket being used for mounting the movable rod.

[0011] In the embodiments of this application, the bag filter also includes a positioning plate installed in the air inlet chamber. The positioning plate is provided with positioning blind holes that correspond one-to-one with a plurality of mounting holes, so that when the bag is installed in the mounting hole, the bottom end of the bag can extend into the corresponding positioning blind hole.

[0012] In embodiments of this application, the bag filter further includes: Two mounting blocks are disposed opposite each other on the inner wall of the air intake chamber along the second direction. The two mounting blocks have mounting slots formed on opposite sides of each other. The two mounting slots are used for the positioning plate to be inserted into the two ends of the second direction respectively. Two fixing components are installed on the two mounting blocks respectively, and the fixing components can fix the positioning plate on the mounting blocks.

[0013] In an embodiment of this application, each mounting block is formed with a limiting hole extending in a first direction, and the limiting hole communicates with the mounting slot. The fixed components include: The clamping member includes a C-shaped main body and two extension portions extending outward from both ends of the main body. The main body has two threaded holes arranged opposite each other in a first direction. The two extension portions extend in the first direction toward a side that is close to each other. The two extension portions are used to extend into the limiting hole from both ends of the limiting hole. The screw and nut are connected by screwing the screw through two threaded holes in sequence.

[0014] In the embodiments of this application, a dust discharge hole is formed in the middle of the bottom wall of the main chamber, and the bottom wall of the main chamber is inclined downward in the direction from the side wall of the main chamber to the dust discharge hole.

[0015] In an embodiment of this application, a rotating cover is formed on the top wall of the exhaust chamber. The rotating cover is rotatably installed on the dust collector body and can rotate toward the exhaust chamber to seal the exhaust chamber.

[0016] In embodiments of this application, the bag filter further includes a sealing strip affixed to the main body chamber, the sealing strip being affixed to the periphery of the rotating cover and / or mounting hole.

[0017] As can be seen from the above technical solution, when using a baghouse dust collector, the bag frame needs to be installed inside the bag to open it. Then, the bag needs to be inserted into the mounting hole, and the two mounting units in the corresponding mounting assembly move in a second direction toward each other, thus securing the bag. When the bag needs to be replaced, the two mounting units are controlled to move away from each other, thereby releasing the bag's fixation. At this time, the bag can be pulled out directly for replacement. After replacement, the two mounting units are controlled to re-secure the bag. In this application, the baghouse dust collector can quickly install and fix the bag using two mounting units, and the bag can be easily replaced after the two mounting units are released, thus completing bag replacement and installation with extremely high efficiency.

[0025] This application proposes a bag filter dust collector, which aims to solve the problem that in the prior art, the operation required for installing and removing the filter bags in bag filters is relatively complicated, resulting in low efficiency in replacing filter bags and affecting the use of bag filters.

[0026] The bag filter of this application will be further illustrated below through embodiments. These embodiments are implemented based on the technical solution of this application, and detailed implementation methods and specific operating procedures are provided. However, the scope of protection of this application is not limited to the following embodiments. Figures 1 to 3 This is a schematic diagram of an embodiment of the bag filter dust collector proposed in this application.

[0027] See Figure 1 The bag filter 100 proposed in this application includes: The dust collector body 1 has a main chamber 11 inside; Mounting plate 2 is installed inside the main body chamber 11. Mounting plate 2 can divide the main body chamber 11 into an air inlet chamber 111 and an air outlet chamber 112 along the first direction X. The mounting plate 2 has an installation space 21 and multiple mounting holes extending along the first direction X. The multiple mounting holes connect the air inlet chamber 111, the installation space 21 and the air outlet chamber 112 in sequence. Multiple bag assemblies 3 correspond one-to-one with multiple mounting holes. Each bag assembly 3 includes a bag 31 and a bag 31 frame installed inside the bag 31. The bag 31 is installed in the corresponding mounting hole, and the open end of the bag 31 is located in the air outlet chamber 112. Multiple mounting components 4 correspond one-to-one with multiple mounting holes. Each mounting component 4 includes two mounting units 41 disposed opposite each other on both sides of the corresponding mounting hole along the second direction Y. The two mounting units 41 are movably disposed along the second direction Y so as to press against the cloth bag 31 located in the mounting hole when they come close to each other. The first direction X and the second direction Y are set at an angle.

[0028] As can be seen from the above technical solution, when using the bag filter 100, the filter bag 31 frame needs to be installed into the filter bag 31 to open the filter bag 31. Then, the filter bag 31 needs to be inserted into the mounting hole, and the two mounting units 41 in the corresponding mounting assembly 4 move towards each other along the second direction Y, thereby securing the filter bag 31. When the filter bag 31 needs to be replaced, the two mounting units 41 are controlled to move away from each other, thereby releasing the fixation of the filter bag 31. At this time, the filter bag 31 can be pulled out directly for replacement. After replacement, the two mounting units 41 are re-controlled to secure the filter bag 31. In this application, the bag filter 100 can quickly complete the installation and fixation of the filter bag 31 through the two mounting units 41, and after the two mounting units 41 release the fixation of the filter bag 31, the filter bag 31 can also be easily replaced, thus completing the replacement and installation of the filter bag 31 with extremely fast efficiency.

[0029] Specifically, the shape of the mounting plate 2 corresponds to the shape of the main chamber 11, thereby enabling the mounting plate 2 to divide the main chamber 11 into an inlet chamber 111 and an outlet chamber 112. Gas exchange between the inlet chamber 111 and the outlet chamber 112 occurs only through the filter bag 31, at which point the filter layer on the filter bag 31 achieves dust removal. The baghouse dust collector 100 also includes an inlet mechanism and an outlet mechanism installed on the outside of the dust collector body 1. The inlet mechanism is connected to the inlet chamber 111, and the outlet mechanism is connected to the outlet chamber 112. The inlet mechanism is used to draw dust-laden gas from the outside into the inlet chamber 111, and the outlet mechanism is used to discharge the air in the outlet chamber 112 to the outside. As mentioned above, the gas flow trajectory is as follows: first, it enters the inlet chamber 111 from the outside through the inlet mechanism, then passes through the filter bag 31 and enters the outlet chamber 112, and finally returns to the outside from the outlet chamber 112 through the outlet mechanism. During this process, as the gas passes through the filter bag 31, dust and impurities adhere to the filter bag 31, thus completing the dust removal.

[0030] In this application, both the mounting space 21 and the mounting holes are formed within the mounting plate 2, and the mounting units 41 are all installed within the mounting space 21. However, in another embodiment of this application, two mounting plates 2 may be provided at intervals along the first direction X, thereby dividing the main body chamber 11 into three parts: an air inlet chamber 111, an air outlet chamber 112, and the mounting space 21. The mounting units 41 are disposed on the lower mounting plate 2, and each mounting hole is adjusted to be two mounting holes opposite each other on the two mounting plates 2 along the first direction X. With this arrangement, the size of the mounting space 21 is more flexible, the processing difficulty is lower, and the installation of the mounting units 41 is more convenient.

[0031] Furthermore, the first direction X and the second direction Y are two opposite directions and can be adjusted according to actual needs. In this application, the first direction X is the up-down direction, and the second direction Y is the left-right direction.

[0032] Specifically, see Figure 1 and Figure 2 The mounting unit 41 includes a top block 411 and a movable rod 412 extending along the second direction Y. The movable rod 412 is movably arranged along the second direction Y, and the top block 411 is mounted on one end of the movable rod 412 near the mounting hole.

[0033] In each mounting assembly 4, when two mounting units 41 need to move closer together, the movable rods 412 of the two mounting units 41 will move along the second direction Y towards the direction of mutual approach, thereby driving the two top blocks 411 to move closer together, thus clamping the cloth bag 31 located between the two top blocks 411. The movable rods 412 can be driven by a servo cylinder, or a spring can be fitted on the movable rods 412. One end of the spring abuts against the side wall of the mounting space 21, and the other end abuts against the top block 411. The preload of the spring can push the top block 411 to move towards the cloth bag 31. When it is necessary to release the fixation of the cloth bag 31, the two top blocks 411 can be manually opened to release the cloth bag 31. Of course, there are many other ways to drive the movable rods 412, which are not limited here, as long as they can drive the movable rods 412 to move.

[0034] Furthermore, each mounting component 4 also includes a limiting member 42 mounted on the mounting plate 2, which can limit the two top blocks 411 when the two mounting units 41 are pressed against the cloth bag 31.

[0035] When the mounting unit 41 is not equipped with an additional driving component, the worker can manually push the top block 411 to bring it closer to and abut against the cloth bag 31, but this is not enough to secure the cloth bag 31. In this embodiment, the mounting assembly 4 also includes a limiting member 42, which can limit the two top blocks 411 to the position abutting against the cloth bag 31 when the two mounting units 41 are abutting against the cloth bag 31, thereby keeping the top blocks 411 abutting against the cloth bag 31 and completing the fixation of the cloth bag 31.

[0036] Furthermore, see Figure 1 and Figure 2The limiting member 42 includes a rotating part 421 and two abutting rods 422. The rotating part 421 is arranged in a ring shape and sleeved outside the corresponding mounting hole. The rotating part 421 is rotatably mounted on the side of the mounting plate 2 near the air outlet chamber 112 about an axis in the first direction X. One end of each of the two abutting rods 422 is connected to the bottom end of the rotating part 421. The two abutting rods 422 extend along the first direction X and are arranged opposite each other along a diameter of the rotating part 421. The mounting plate 2 has an arc-shaped hole corresponding to the rotation trajectory of the rotating part 421, so that the two abutting rods 422 can extend into the mounting space 21 and rotate together with the rotating part 421. When the two mounting units 41 are pressed against the cloth bag 31, the two abutting rods 422 can rotate to the side of a top block 411 away from the cloth bag 31.

[0037] In this embodiment, two abutment rods 422 are installed within the mounting space 21, with one end of each rod extending from a corresponding arc-shaped hole and connecting to the bottom of the rotating part 421. The shape of the arc-shaped hole corresponds to the rotation trajectory of the rotating part 421, allowing the rotating part 421 to rotate and drive the two abutment rods 422 to move together. The rotating part 421 is annularly arranged and fitted outside the corresponding mounting hole, so the movement trajectory of the two abutment rods 422 passes through the side of the two top blocks 411 away from the bag 31. In practical application, when a worker pushes the two top blocks 411 against the bag 31 with one hand, the other hand can rotate the rotating part 421. The rotating part 421 will drive the two abutment rods 422 to move together, causing each abutment rod 422 to rotate to the side of one top block 411 away from the bag 31, keeping the two top blocks 411 in a state of pressing against the bag 31. The limiting component 42 has a simple structure, low production cost, and is easy to operate, making it highly practical.

[0038] In practical applications, when the abutment rod 422 rotates toward the side of the top block 411 away from the bag 31, the worker needs to press the top block 411 firmly to ensure that the top block 411 fits tightly against the bag 31, preventing interference between the top block 411 and the abutment rod 422 and ensuring that the abutment rod 422 can move smoothly to the side of the top block 411 away from the bag 31. However, this installation method is somewhat difficult. Therefore, further, each installation unit 41 also includes an elastic element 413, which is located on the side of the top block 411 closest to the bag 31.

[0039] When the elastic element 413 is provided on the top block 411, the elastic element 413 will replace the top block 411 in contact with the cloth bag 31. When the worker presses the top block 411 hard, the elastic element 413 will fit tightly against the cloth bag 31 and undergo elastic deformation. At this time, the force required by the worker is relatively smaller, and the installation difficulty is greatly reduced. Most importantly, after the abutment rod 422 completes the limiting of the top block 411, the elastic element 413 will remain in the elastic deformation state, thereby applying a stable pre-tightening force to the cloth bag 31. In addition, in this embodiment, the top block 411 will be relatively closer to the cloth bag 31 when the elastic element 413 elastically deforms, thereby making the movement of the abutment rod 422 smoother.

[0040] Specifically, the type of elastic element 413 is not limited here. It can be a spring or a soft pad made of elastic material, as long as it can undergo elastic deformation.

[0041] See Figure 1 and Figure 2 In one embodiment of this application, each mounting unit 41 further includes a mounting bracket 414 disposed within the mounting space 21, which is used for mounting the movable rod 412. One end of the movable rod 412 away from the top block 411 is connected to the side wall of the mounting space 21, and the middle portion of the movable rod 412 is connected to the mounting bracket 414, thereby making the mounting of the movable rod 412 more stable. The mounting bracket 414 does not restrict the movement of the movable rod 412 along the second direction Y, but it does restrict the movement of the movable rod 412 in other directions, preventing unnecessary shaking of the movable rod 412.

[0042] See Figure 1 and Figure 3 In any of the above embodiments, the bag filter 100 further includes a positioning plate 5 installed in the air inlet chamber 111. The positioning plate 5 is provided with positioning blind holes 51 corresponding to a plurality of mounting holes, so that when the bag 31 is installed in the mounting hole, the bottom end of the bag 31 can extend into the corresponding positioning blind hole 51.

[0043] During installation, the filter bag 31 extends into the air intake chamber 111 through the mounting hole, and then into the positioning blind hole 51, abutting against the bottom end of the positioning blind hole 51. During the positioning process of the filter bag 31, the bottom wall of the positioning blind hole 51 presses against the bottom of the filter bag 31, thereby limiting the filter bag 31 to a suitable installation position. During the installation of the filter bag 31, the side wall of the positioning blind hole 51 limits the filter bag 31, preventing unnecessary shaking during use. In this embodiment, the positioning plate 5, through the positioning blind hole 51, enables more accurate installation and more stable use of the filter bag 31.

[0044] In practical use, the positioning plate 5 needs to position the cloth bag 31, therefore the position of the positioning plate 5 itself needs to be accurate and stable. Therefore, further refer to... Figure 1 and Figure 3 The bag filter 100 also includes: Two mounting blocks 101 are disposed opposite each other on the inner wall of the air intake chamber 111 along the second direction Y. The two mounting blocks 101 have mounting slots on opposite sides, and the two mounting slots are used for the positioning plate 5 to be inserted into both ends in the second direction Y. Two fixing components are installed on the two mounting blocks 101 respectively, and the fixing components can fix the positioning plate 5 on the mounting block 101.

[0045] In this embodiment, two mounting blocks 101 are fixedly installed on the inner wall of the intake chamber 111, and the two ends of the positioning plate 5 are inserted into the mounting slots, thus being installed together with the two mounting blocks 101 on the inner wall of the intake chamber 111. Furthermore, each fixing component can reinforce the corresponding mounting block 101, further enhancing the stability of the mounting block 101 and the positioning plate 5. In actual installation, the two mounting blocks 101, the positioning plate 5, and the fixing components are first assembled, and then installed into the intake chamber 111, which is more convenient.

[0046] Specifically, each mounting block 101 has a limiting hole extending along the first direction X, and the limiting hole communicates with the mounting slot; the fixing assembly includes a clamping member 102, a screw 103, and a nut 104. The clamping member 102 includes a C-shaped main body 1021 and two extension portions extending outward from both ends of the main body 1021. The main body 1021 has two threaded holes arranged opposite each other along the first direction X. The two extension portions extend along the first direction X and toward the side that is close to each other. The two extension portions are used to extend into the limiting hole from both ends of the limiting hole; the screw 103 passes through the two threaded holes in sequence, and the nut 104 is screwed to the screw 103.

[0047] During installation, the two protruding parts of the clamping member 102 extend into the limiting hole from both ends and contact the positioning plate 5 in the mounting slot. Then, the screw 103 passes through the two threaded holes in sequence, and finally the screw 103 is locked with the nut 104, so that the two protruding parts press against the positioning plate 5 in the mounting slot, thereby completing the reinforcement of the positioning plate 5.

[0048] In addition, the fixing component can also be installed with the fixing plate 5 through other embodiments, such as by increasing the number of mounting blocks 101, or by increasing the number of connection points between the side wall of the air intake chamber 111 and the positioning plate 5. It is not limited to the above embodiments.

[0049] See Figure 1The size of solid particles in dusty gas varies considerably. Smaller solid particles move with the gas, while larger solid particles may deposit inside the main chamber 11. Therefore, in one embodiment of this application, a dust discharge hole 113 is formed in the middle of the bottom wall of the main chamber 11. The bottom wall of the main chamber 11 is inclined downwards in the direction from the side wall of the main chamber 11 to the dust discharge hole 113. Larger solid particles, after deposition, will fall onto the bottom wall of the main chamber 11 and slide down along the bottom wall, gradually approaching the dust discharge hole 113. The dust discharge hole 113 is normally closed, but can be selectively opened. For example, the bag filter 100 can have a bottom cover corresponding to the dust discharge hole 113, and the bottom cover can be screwed onto the dust discharge hole 113. When it is necessary to open the dust discharge hole 113, the bottom cover is removed; when it is necessary to close the dust discharge hole 113, the bottom cover is screwed onto the dust discharge hole 113. Of course, the dust collector 100 can also control the opening and closing of the dust discharge port 113 in other ways, which will not be listed here.

[0050] In this embodiment, a rotating cover 12 is formed on the top wall of the exhaust chamber 112. The rotating cover 12 is rotatably mounted on the dust collector body 1, and can rotate towards the exhaust chamber 112 to seal it. When the filter bag 31 needs to be replaced, the worker can rotate the rotating cover 12 away from the exhaust chamber 112 to open it and begin the replacement operation. After replacement, the worker can rotate the rotating cover 12 towards the exhaust chamber 112 to seal it. The rotating cover 12 simplifies the operation of opening the exhaust chamber 112, making filter bag 31 replacement more convenient.

[0051] Furthermore, the bag filter 100 also includes a sealing strip 105 affixed to the main body chamber 11, and the sealing strip 105 is affixed to the periphery of the rotating cover plate 12 and the mounting hole. The sealing strip 105 can increase the sealing performance of the main body 1 of the dust collector and ensure the dust removal effect of the bag filter 100.

[0052] The sealing strip 105 is affixed to the periphery of the rotating cover 12 to prevent direct gas exchange between the outlet chamber 112 and the outside environment, thus preventing external gas from contaminating the outlet chamber 112. The sealing strip 105 is also affixed to the periphery of the mounting hole to prevent direct gas exchange between the inlet chamber 111 and the outlet chamber 112, ensuring that dust-laden gas passes through the filter bag 31 before entering the outlet chamber 112, thus guaranteeing the dust removal efficiency of the bag filter 100. Of course, there may not necessarily be a sealing problem between the periphery of the rotating cover 12 and the periphery of the mounting hole; therefore, the sealing strip 105 can be affixed to either the periphery of the rotating cover 12 or the periphery of the mounting hole, or it can be affixed to other parts within the main chamber 11. No restrictions are placed here.

[0053] The preferred embodiments of this application have been described in detail above; however, this application is not limited thereto. Within the scope of the technical concept of this application, various simple modifications can be made to the technical solution of this application, including combining various technical features in any other suitable manner. These simple modifications and combinations should also be considered as the content disclosed in this application and are all within the protection scope of this application.
