Description

A bag filter with a detachable structure Technical Field

[0001] This utility model relates to a bag filter dust collector, specifically a bag filter dust collector with a detachable structure, and belongs to the technical field of bag filter dust collectors. Background Technology

[0002] A baghouse dust collector, also known as a filter dust collector, is a purification device that uses organic or inorganic fiber filter cloth to filter dust from gas. It is also a widely used dry dust filtration device, suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt. The filtration effect of the fibrous fabric is used to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, large and heavy dust particles settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter media, the dust is trapped, thus purifying the gas. In common baghouse dust collectors, the filter bags are fixed by engaging the expansion ring at the top of the filter bag with the tube sheet.

[0003] However, when disassembling a traditional baghouse dust collector, one hand needs to hold one side of the expansion ring while the other hand grasps the other side of the expansion ring and pulls it inward to release the expansion ring from the tube sheet. During the operation, inexperienced workers may not be able to coordinate their hands properly or apply uneven force. When the expansion ring comes out of the mounting hole in the tube sheet, they may not be able to hold the filter bag firmly, and the filter bag will fall into the dust collector due to gravity. In addition, after long-term use, the expansion ring is prone to elastic fatigue, which reduces the elasticity of the expansion ring. Also, if the expansion ring is not properly and evenly engaged with the tube sheet during installation, the filter bag may fall into the dust collector. Summary of the Invention

[0004] The purpose of this utility model is to provide a bag filter with a detachable structure to solve the above problems. The method of inserting the mounting ring and the mounting hole makes the installation of the filter bag more convenient and the disassembly simple, which improves the maintenance efficiency. The cooperation between the protrusion and the pressure block not only increases the stability of the filter bag and the bag cage installation, but also improves the sealing effect of the filter bag.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1-6. A baghouse dust collector with a detachable structure includes a dust collector body 1. A tube sheet 2 is fixedly connected inside the dust collector body 1. Multiple rows of mounting holes 3 are formed on the tube sheet 2. Filter bags 4 are installed in the mounting holes 3 through a detachable structure 5. The detachable structure 5 includes a mounting ring 501. The top end of the filter bag 4 is fixedly connected to the mounting ring 501. The mounting ring 501 is inserted into the mounting hole 3. A rubber ring 5 is sleeved on the outside of the mounting ring 501. 02, the rubber ring 502 abuts against the tube sheet 2, the filter bag 4 is inserted with a bag cage 503, the bag cage 503 is fixedly connected with two protrusions 504, the protrusions 504 are trapezoidal in structure, the tube sheet 2 is fixedly connected with multiple sets of pressure blocks 505, the protrusions 504 abut against the pressure blocks 505, the same set of pressure blocks 505 are symmetrically arranged about the center of the mounting hole 3, the cross section of the pressure block 505 is "L" shaped, and the dust collector body 1 is equipped with a dust removal structure 6.

[0023] As a technical optimization of this utility model, the cross-section of the mounting ring 501 is T-shaped, the outer wall of the rubber ring 502 is inclined, and the top cross-section of the bag cage 503 is T-shaped, which can prevent the filter bag 4 from falling into the dust collector body 1, thereby increasing the stability of the filter bag 4 installation. Multiple sets of positioning posts 510 are fixedly connected on the tube sheet 2, and positioning holes 511 are opened on the mounting ring 501. The positioning posts 510 are inserted into the positioning holes 511. The positioning of the filter bag 4 is quickly achieved by the insertion of the positioning posts 510 into the positioning holes 511, which increases the stability of the filter bag 4 installation.

[0024] As a technical optimization of this utility model, a rod 507 is inserted into the protrusion 504. The top ends of multiple rods 507 in the same row are fixedly connected to the same pressure strip 506. The pressure strip 506 drives multiple rods 507 in the same row to pass through the pressure block 505 and then insert into the protrusion 504, thereby quickly limiting the multiple protrusions 504. A knob 509 is rotatably connected to the pressure strip 506. A fixing block 508 is fixedly connected to the flower plate 2. The end of the knob 509 is threadedly connected to the fixing block 508. The threaded connection between the knob 509 and the fixing block 508 further increases the stability of the insertion of the rod 507 into the protrusion 504.

[0025] As a technical optimization of this utility model, the dust removal structure 6 includes a mounting frame 601. The mounting frame 601 is fixedly connected to the outer wall of the dust collector body 1. An air tank 602 is fixedly connected to the mounting frame 601. Multiple blow pipes 603 are installed on the air tank 602. Multiple nozzles 604 are fixedly connected to the blow pipes 603. The multiple blow pipes 603 are arranged in a linear array. The nozzles 604 are located directly above the filter bag 4. The dust removal structure 6 cleans the filter bag 4 to prevent the filter bag 4 from weakening the filtration effect due to excessive dust adhering to it.

[0026] As a technical optimization of this utility model, an air inlet 7 is installed on the lower side wall of the dust collector body 1, an air outlet 8 is installed on the upper side wall of the dust collector body 1, and a dust outlet 9 is installed at the bottom of the dust collector body 1. The dust collector body 1 draws in dust-laden gas through the air inlet 7 on the lower side wall. After internal filtration, the purified gas is discharged through the air outlet 8 on the upper side wall, while the settled dust is discharged through the dust outlet 9 at the bottom, thereby realizing the functions of dust removal and separation and discharge of related substances.

[0027] In use, when installing the filter bag 4, firstly, align the positioning hole 511 on the mounting ring 501 with the positioning post 510 on the tube sheet 2, and then insert the filter bag 4 into the mounting hole 3 until the positioning post 510 is inserted into the positioning hole 511. During the insertion process of the mounting ring 501 into the mounting hole 3, the mounting ring 501 drives the rubber ring 502 to abut against the tube sheet 2. Since the outer wall of the rubber ring 502 has a beveled structure, it can tightly fit the surface of the tube sheet 2, creating a good seal between the filter bag 4 and the tube sheet 2 to prevent the leakage of dust-laden gas. The insertion of the mounting ring 501 into the mounting hole 3 makes the installation of the filter bag 4 convenient; then install... The bag cage 503 is inserted into the filter bag 4. During installation, the protrusions 504 on the bag cage 503 should be offset from the pressure blocks 505 on the tube sheet 2. After the bag cage 503 is fully inserted into the filter bag 4, rotate the bag cage 503 so that the protrusions 504 gradually come into contact with the pressure blocks 505. Since the protrusions 504 have a trapezoidal structure, as the mounting ring 501 rotates, the protrusions 504 and pressure blocks 505 will come into closer contact, thereby fixing the bag cage 503 onto the filter bag 4. This allows the filter bag 4 to maintain its shape with the help of the bag cage 503, and the mutual contact between the protrusions 504 and pressure blocks 505 presses the bag cage 503 downwards for installation. Ring 501 is installed so that the installation ring 501 drives the rubber ring 502 to maintain tight contact with the tube sheet 2, thereby further enhancing the sealing effect of the filter bag 4; then, the multiple insert rods 507 on the pressure strip 506 are aligned with the multiple pressure blocks 505 in the same row, and the pressure strip 506 is moved downward until the insert rod 507 passes through the corresponding pressure block 505 and is inserted into the insertion hole on the protrusion 504. Then, the knob 509 is rotated so that the end of the knob 509 is threadedly connected to the fixing block 508, thereby limiting the insertion rod 507 against the protrusion 504, preventing the protrusion 504 from rotating outside the pressure block 505, thereby increasing the sealing effect of the protrusion 504 and the pressure block 505. 05 Stability of contact; When disassembling and cleaning filter bag 4, turn the knob 509 on the pressure bar 506 to disengage the end of the knob 509 from the fixing block 508, lift the pressure bar 506 upward, and pull the insertion rod 507 out of the protrusion 504 to release the additional fastening measures on the bag cage 503. Then rotate the bag cage 503 so that the protrusion 504 no longer contacts the pressure block 505, thereby releasing the limitation on the bag cage 503. Then take out the bag cage 503 and filter bag 4 in sequence, so that the filter bag 4 is easy to disassemble and can effectively prevent the filter bag 4 from falling into the dust collector body 1 during disassembly compared with the traditional filter bag 4 disassembly method.When dust removal is required, the switch of the dust collector body 1 is turned on. Dust-laden gas enters the internal space of the dust collector body 1 through the air inlet 7 at a certain flow rate and direction. The dust-laden gas entering the dust collector body 1 flows upward and comes into contact with the filter bags 4. The filter bags 4 perform a filtering function, and dust particles are intercepted on the outer surface of the filter bags 4, while clean gas passes through the filter bags 4. Because the filter bags 4 are firmly connected to the tube sheet 2 through the mounting ring 501, rubber ring 502 and bag cage 503, and the rubber ring 502 ensures airtightness, the dust-laden gas can only be filtered through the filter bags 4, ensuring high efficiency. The purified gas is discharged through outlet 8, completing the purification and emission process. Filtration continues, and dust accumulation on the outer surface of filter bags 4 increases, affecting filtration efficiency. At this point, the dust removal structure 6 is activated. Compressed air from the air tank 602 is ejected at high speed from nozzle 604 through the blowpipe 603. The powerful airflow impacts the filter bags 4, causing them to expand and shake instantly, shaking off the attached dust. The dust shaken off by the dust removal process then settles to the bottom of the dust collector under gravity and is discharged through the ash outlet 9 at the bottom of the dust collector body 1 for centralized collection and treatment.
