Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cloth bag dust collector, and particularly relates to a cloth bag dust collector for dust treatment in a packaging workshop. BACKGROUND

[0002] The cloth bag dust collector is a dust filtering device widely used in industrial production. The dust collector forms a negative pressure in the dust removal box through a negative pressure fan, and the dust-containing gas is sucked into the box body. The dust is intercepted by the filter bag, and the purified gas is discharged. The dust accumulated on the surface of the filter bag is periodically cleaned by high-pressure gas of the back blowing system to maintain the filtering efficiency. However, the prior art has the following defects:

[0003] 1. When the traditional cloth bag dust collector works, the high negative pressure formed in the dust removal box will cause the filter bag to deform inward, so that the inner surface of the filter bag is tightly attached to the cage framework. When the back blowing system injects high-pressure gas, the filter bag and the cage framework will produce intense friction, which will easily cause the filter bag to wear out or even break after long-term use, thereby shortening the service life and increasing the maintenance cost.

[0004] 2. When the back blowing system cleans the filter bag, the high-pressure airflow will blow part of the dust back into the air inlet pipeline and escape into the workshop along with the airflow, thereby causing secondary pollution of the working environment, affecting the production cleanliness and the health of the employees.

[0048] Example

[0049] To address the technical problems in the background section, the following baghouse dust collector for dust treatment in packaging workshops is provided:

[0050] Combination Figures 1-15As shown, the present invention provides a baghouse dust collector for dust treatment in a packaging workshop, comprising a support frame 100, a treatment tank 200 fixedly connected to the middle of the support frame 100, a bag assembly 300 installed in the upper part of the inner cavity of the treatment tank 200, a cleaning component 400 installed on the bottom surface of the bag assembly 300, a backflushing component 500 installed on the top surface of the bag assembly 300, an air inlet component 600 installed on the surface of the treatment tank 200, and an air inlet component 600 located on the inner wall of the treatment tank 200 and within the air inlet component 600. A ring baffle assembly 700 is installed on one side of the processing tank 200, a receiving assembly 800 is installed on the bottom surface of the processing tank 200, and an exhaust fan 900 is fixedly connected to the top surface of the support frame 100. The input end of the exhaust fan 900 is connected to the upper part of the inner cavity of the processing tank 200. The bag assembly 300 includes a disc 301, which is fixedly connected to the upper part of the inner wall of the processing tank 200. The top surface of the disc 301 has a circumferential array of bag holes 302, and a bag component is placed in the bag hole 302. The component contains a cage frame assembly; the cage frame assembly includes a pressure plate 303 and a hollow circular tube 304. A vertical tube 305 is symmetrically and fixedly connected to the bottom surface of the pressure plate 303. A vertical airbag 306 is fixedly connected to the surface of the vertical tube 305, and the vertical airbag 306 communicates with the vertical tube 305. Semi-circular tubes 307 are fixedly connected at equal intervals between two sets of vertical tubes 305. A semi-circular airbag 308 is fixedly connected to the surface of the semi-circular tube 307, and the semi-circular airbag 308 communicates with the semi-circular tube 307. A diversion pipe 309 is fixedly connected at equal intervals to the lower part of the surface of the hollow tube 304. One end of the diversion pipe 309 is fixedly connected to the semi-arc tube 307. A first reinforcing rod 310 is fixedly connected between the pressure plate 303 and the semi-arc tube 307. A second reinforcing rod 311 is fixedly connected between the two sets of semi-arc tubes 307. An air injection pipe 312 is fixedly connected to the upper part of the surface of the hollow tube 304. One end of the air injection pipe 312 is connected to the inner cavity of the vertical tube 305. A valve is installed inside the air injection pipe 312.

[0051] The vertical airbag 306 reduces the contact between the filter bag and the cage component during dust removal, thus preventing the filter bag from being damaged due to wear.

[0052] The vertical airbag 306 and the semi-circular airbag 308 work together to open up the bag component, ensuring that there are no wrinkles in the bag component during the initial installation, and allowing the cleaning brush 405 to fully contact the surface of the bag component during the later cleaning process.

[0053] In this embodiment, the bag component includes a columnar bag 313, and a first rubber ring 314 and a second rubber ring 315 are fixedly connected to the upper surface of the columnar bag 313.

[0054] The first rubber ring 314 and the second rubber ring 315 are used to fix the columnar cloth bag 313 in the bag hole 302 and also seal the bag hole 302.

[0055] In this embodiment, the cleaning component 400 includes a lifting motor 401 and a guide rod 402. The lifting motor 401 is fixedly connected to the top surface of the disc 301, and the guide rod 402 is fixedly connected to the bottom surface of the disc 301. A lifting threaded rod 403 is fixedly connected to the output shaft end of the lifting motor 401, and a cleaning component is installed on the surface of the lifting threaded rod 403.

[0056] The lifting motor 401 drives the lifting threaded rod 403 to rotate, thereby driving the cleaning component to move up and down on the surface of the bag component under the action of the guide rod 402, thus achieving the cleaning of the surface of the bag component.

[0057] In this embodiment, the cleaning component includes a lifting disc 404. The lifting disc 404 is threadedly connected to the surface of the lifting threaded rod 403. The lifting disc 404 slides on the surface of the guide rod 402. A cleaning brush cylinder 405 is rotatably connected inside the lifting disc 404. The cleaning brush cylinders 405 are arranged in a circumferential array on the lifting disc 404. A rotating gear 406 is fixedly connected to the surface of the cleaning brush cylinder 405. Multiple sets of cleaning brush cylinders 405 are rotatably connected through the rotating gear 406. A motor frame 407 is fixedly connected to the bottom surface of the lifting disc 404. A cleaning motor 408 is fixedly connected to one side of the motor frame 407. A cleaning gear 409 is fixedly connected to the output end of the cleaning motor 408. The cleaning gear 409 meshes with the rotating gear 406.

[0058] The cleaning motor 408 drives the cleaning gear 409 to rotate, which in turn drives a set of rotating gears 406 to rotate. When the rotating gears 406 rotate, they will drive the cleaning brush cylinder 405 to rotate. The remaining cleaning brush cylinder 405 rotates under the action of the meshing rotating gears 406, and begins to clean the dust on the surface of the cloth bag component.

[0059] In this embodiment, the ring baffle assembly 700 includes a T-shaped ring 701 and an extension rod 702. The T-shaped ring 701 is fixedly connected to the inner wall of the treatment tank 200. A water flow chamber 703 is provided inside the T-shaped ring 701. Air vents 704 are symmetrically arranged on the surface of the T-shaped ring 701. The extension rod 702 is fixedly connected to the bottom surface of the lifting threaded rod 403. A cross 705 is fixedly connected to the bottom surface of the extension rod 702. A blocking ring 706 is fixedly connected to one end of the cross 705. The blocking ring 706 is rotatably connected to the bottom surface of the T-shaped ring 701. A cleaning brush 707 is fixedly connected to the top surface of the blocking ring 706.

[0060] The injected flue gas is dispersed by the T-ring 701, and the flue gas is cooled by the coolant in the water chamber 703, which avoids the hot gas burning the columnar filter bag 313. At the same time, the flue gas is dispersed and cooled again by the air outlet 704, which can also filter out larger impurities in the flue gas.

[0061] The lifting threaded rod 403 drives the extension rod 702, the cross 705 and the blocking ring 706 to rotate. When the blocking ring 706 rotates, it will drive the cleaning brush 707 to rotate in a circle, thereby cleaning the inner wall of the treatment tank 200 and the inside of the T-ring 701. The cleaned impurities will fall down from the gap between the blocking ring 706 and the treatment tank 200.

[0062] In this embodiment, the backflush assembly 500 includes a pressure pneumatic rod 501 and a backflush tank 502. The backflush tank 502 is fixedly connected to the top surface of the support frame 100, and the pressure pneumatic rod 501 is fixedly connected to the top surface of the disc 301. A bent rod 503 is fixedly connected to the output end of the pressure pneumatic rod 501. An annular air pipe 504 is fixedly connected to one end of the bent rod 503. Sealing cylinders 505 are fixedly connected at equal intervals to the inner wall of the annular air pipe 504. The inner cavity of the sealing cylinder 505 communicates with the inside of the annular air pipe 504. The output end of the backflush tank 502 is connected to the annular air pipe 504 through a first flexible hose 506.

[0063] By pressing down the pneumatic rod 501, the annular air tube 504 and the sealing cylinder 505 are moved downward, so that one end of the sealing cylinder 505 is inserted into the top of the columnar cloth bag 313. Then, the backflushing tank 502 is used to inject air into the columnar cloth bag 313, and the gas begins to blow out the dust adhering to the surface of the columnar cloth bag 313.

[0064] In this embodiment, the recoil assembly 500 also includes an air pump 507. The air pump 507 is fixedly connected to the top surface of the support frame 100. The output end of the air pump 507 is fixedly connected to a second hose 508. One end of the second hose 508 is fixedly connected to an inflation ring 509. An inflation tube 510 is fixedly connected at equal intervals on the surface of the inflation ring 509. One end of the inflation tube 510 passes through the sealing cylinder 505 and is fixedly connected to the sealing cylinder 505.

[0065] Gas is injected into the inflation ring 509 by the air pump 507, allowing the gas to enter the inflation tube 510 from the inflation ring 509 and then be discharged from the inflation tube 510. The gas is also injected into the vertical airbag 306 and the semi-circular airbag 308. When both the vertical airbag 306 and the semi-circular airbag 308 are full of gas, the columnar cloth bag 313 expands, and the cleaning brush 405 can clean the surface of the columnar cloth bag 313 later. When the inflation stops, the vertical airbag 306 retains gas due to the one-way valve, while the semi-circular airbag 308 flattens. At this time, the vertical airbag 306 can prevent the columnar cloth bag 313 from contacting the cage components, thus avoiding wear and damage to the columnar cloth bag 313 due to friction.

[0066] In this embodiment, the receiving assembly 800 includes a transfer box 801. The transfer box 801 is fixedly connected to the bottom surface of the processing tank 200. The inner cavity of the transfer box 801 communicates with the inner cavity of the processing tank 200. A dustproof hole 802 is provided on one side of the transfer box 801. A first inclined plate 803 is fixedly connected to the top surface of the inner wall of the transfer box 801. A second inclined plate 804 is fixedly connected to the bottom surface of the inner wall of the transfer box 801. The first inclined plate 803 and the second inclined plate 804 are staggered. A slot 805 is provided on the bottom surface of the transfer box 801 and on one side of the second inclined plate 804. A receiving box 806 is slidably connected in the slot 805. A blocking rod 807 is rotatably connected to the surface of the transfer box 801.

[0067] By cooperating with the first inclined plate 803 and the second inclined plate 804, the airflow and dust coming down from the reverse flow can be blocked, preventing dust from overflowing from the dustproof hole 802.

[0068] In this embodiment, the receiving assembly 800 also includes an opening and closing pneumatic rod 808. The opening and closing pneumatic rod 808 is fixedly connected to the surface of the transfer box 801. An opening and closing rod 809 is fixedly connected to the output end of the opening and closing pneumatic rod 808. An opening and closing plate 810 is fixedly connected to one end of the opening and closing rod 809. One end of the opening and closing plate 810 penetrates the bottom surface of the transfer box 801 and slides inside the transfer box 801.

[0069] The opening and closing pneumatic rod 808 drives the opening and closing rod 809 to move, thereby causing the opening and closing plate 810 to move downward or upward. When the opening and closing plate 810 moves downward, it facilitates the later cleaning of the columnar filter bag 313, allowing the air inside the treatment tank 200 to be discharged while the dust is blocked. When the opening and closing plate 810 moves upward, it makes the transfer box 801 sealed, facilitating the later dust removal of external gas by the bag filter.

[0070] In this embodiment, the air intake assembly 600 includes an air intake pipe 601. The air intake pipe 601 is fixedly connected to the surface of the processing tank 200. An arc-shaped block 602 is fixedly connected to the surface of the air intake pipe 601. The inner cavity of the arc-shaped block 602 communicates with the inner cavity of the air intake pipe 601. A fan-shaped sealing block 603 is slidably connected inside the arc-shaped block 602. A sealing rod 604 is fixedly connected to the top surface of the fan-shaped sealing block 603. One end of the sealing rod 604 is fixedly connected to the opening and closing rod 809.

[0071] When the sector-shaped sealing block 603 moves along the arc-shaped block 602 into the air inlet pipe 601, it seals the air inlet pipe 601, preventing the gas generated by backflow from entering the workshop. The upward movement of the sector-shaped sealing block 603 opens the air inlet pipe 601, facilitating the subsequent treatment of the gas discharged into the treatment tank 200.

[0072] Working principle and usage process of this invention:

[0073] In use:

[0074] Preliminary preparations:

[0075] The first step is to connect the inlet and outlet pipes of the external cooling water pipes to the T-ring 701 and to the water flow chamber 703.

[0076] The second step is to connect the external air duct to the air inlet pipe 601, at which point the air inlet pipe 601 is connected to the treatment tank 200.

[0077] The third step is to install the bag assembly. During installation, firstly, one end of the cylindrical bag 313 passes through the bag hole 302. After passing through, the worker deforms the second rubber ring 315 and the first rubber ring 314, causing the second rubber ring 315 to pass through the bag hole 302. Then, the first rubber ring 314 and the second rubber ring 315 are released, so that the first rubber ring 314 and the second rubber ring 315 are respectively secured on both sides of the disc 301. This completes the installation of the bag assembly. After installation, one end of the cage assembly is inserted into the cylindrical bag 313. Once fully inserted, then... The pressure plate 303 will be positioned on the top surface of the first rubber ring 314 and will press down on it. After the cage frame components are installed, the annular air pipe 504 will be installed, fixing it to the downward pressure pneumatic rod 501. After installation, the annular air pipe 504 and the inflation ring 509 will be fixed. Then, the annular air pipe 504 will be connected to the external backflushing tank 502, while the inflation ring 509 will be connected to the air pump 507. After connection, the downward pressure pneumatic rod 501 will drive the annular air pipe 504 and the inflation ring 509 to move downward. As the annular air pipe 504 moves downward, the annular air pipe 504 and the inflation ring 509 will move downward. One end of the sealing cylinder 505 is inserted into one end of the cylindrical cloth bag 313. Simultaneously, the inflation ring 509 moves downwards, causing one end of the inflation tube 510 to insert into the surface of the hollow round tube 304. After insertion, the inflation pump 507 is started. When the inflation pump 507 is working, it inflates the hollow round tube 304 under the action of the inflation tube 510. The gas is then injected into the semi-circular airbag 308 and the vertical airbag 306 respectively through the diversion pipe 309 and the injection pipe 312. Once the semi-circular airbag 308 and the vertical airbag 306 are full of air, the cylindrical cloth bag 313 can be... 13. The columnar cloth bag 313 is opened to prevent it from being clamped to the cage component, and also to prevent damage caused by wrinkles in the columnar cloth bag 313. After the semi-circular airbag 308 and the vertical airbag 306 are fully inflated, the inflation is stopped. At the same time, the pneumatic rod 501 is pressed down to drive the inflation ring 509 of the annular air tube 504 to reset, so that the inflation tube 510 is connected to the hollow round tube 304. At this time, the semi-circular airbag 308 will deflate after the inflation stops, while the vertical airbag 306 still has air due to the one-way valve, which supports it. Finally, the operator seals the treatment tank 200 and can start working.

[0078] During work:

[0079] First, the exhaust fan 900 is started, and the exhaust fan 900 evacuates the treatment tank 200. At the same time, outside gas is injected into the treatment tank 200 through the air inlet pipe 601. At this time, the incoming gas is blocked by the T-ring 701, causing the gas to move along the inner wall of the T-ring 701. When the gas comes into contact with the inner wall of the T-ring 701, it is cooled by the liquid in the water chamber 703. The gas moving along the inner wall of the T-ring 701 will come to the air outlet 704. At this time, the gas will be separated by the air outlet 704, and at the same time, the gas is cooled and larger impurities in the gas are intercepted.

[0080] The gas discharged from the vent 704 will move upward. As the gas moves upward, it will reach the columnar filter bag 313. At this point, the columnar filter bag 313 can begin to filter the smaller dust particles in the gas. After filtration, the filtered gas will be discharged through the exhaust fan 900, thus completing the filtration of impurities and dust in the gas.

[0081] When cleaning the columnar cloth bag 313:

[0082] First, start the opening and closing pneumatic rod 808. When the opening and closing pneumatic rod 808 works, it will drive the opening and closing rod 809 to move. When the opening and closing rod 809 moves, it will drive the opening and closing plate 810 to move. When the opening and closing plate 810 moves, the dust hole 802 will be opened. When the opening and closing rod 809 moves, it will also drive the sealing rod 604 to move. When the sealing rod 604 moves, it will drive the sector-shaped sealing block 603 to move. When the sector-shaped sealing block 603 moves, it will seal the air inlet pipe 601, thereby preventing dust from entering the workshop from the air inlet pipe 601 when cleaning the columnar cloth bag 313.

[0083] At this point, the downward-pressing pneumatic rod 501 is activated. The downward-pressing pneumatic rod 501 will drive the annular air tube 504 and the inflation ring 509 downwards. As the annular air tube 504 moves, the sealing cylinder 505 is inserted above the cylindrical cloth bag 313. The insertion of the inflation tube 510 will cause one end of the inflation tube 510 to be inserted into the surface of the hollow circular tube 304. Then, the inflation pump 507 is activated. When the inflation pump 507 is working, it begins to inflate the vertical airbag 306 and the semi-circular airbag 308. As gas enters the vertical airbag 306, it begins to replenish the air supply to the vertical airbag 306. As gas enters the semi-circular airbag 308, it begins to inflate the semi-circular airbag 308. As the vertical airbag 306 and the semi-circular airbag 308 move downwards, the sealing cylinder 505 is inserted above the cylindrical cloth bag 313. When the arc airbag 308 is opened, it expands the cylindrical filter bag 313. After expansion, the backflushing tank 502 is activated. As the backflushing tank 502 operates, it begins to inflate the cylindrical filter bag 313, causing the gas to blow away dust and impurities adhering to the surface of the bag. After being blown away, the blown-away gas moves towards the bottom of the processing tank 200. As the gas moves downward, it reaches the transfer box 801. The gas then passes through the gap between the first inclined plate 803 and the second inclined plate 804 and is discharged through the air vent 704. The dust is blocked by the first inclined plate 803 and the second inclined plate 804 and falls into the receiving box 806.

[0084] When gas is injected into the cylindrical cloth bag 313, the cleaning motor 408 is started. When the cleaning motor 408 is working, it will drive the cleaning gear 409 to rotate. When the cleaning gear 409 rotates, it will drive the rotating gear 406 to rotate. When the rotating gear 406 rotates, it will start to drive the cleaning brush cylinder 405 to rotate. When the cleaning brush cylinder 405 rotates, it will start to clean the surface of the cylindrical cloth bag 313.

[0085] During cleaning, the lifting motor 401 is activated, driving the lifting threaded rod 403 to rotate. As the lifting threaded rod 403 rotates, it moves the lifting disc 404 downwards under the action of the guide rod 402. This downward movement of the lifting disc 404 causes multiple sets of cleaning brushes 405 to move downwards, allowing them to clean the surfaces of the cylindrical cloth bags 313 of varying lengths. The rotation of the lifting threaded rod 403 also drives the extension rod 702 to rotate, which in turn drives the crossbeam 705 to rotate. The rotating rod will cause the blocking ring 706 and cleaning brush 707 to rotate. As the cleaning brush 707 rotates, it begins to clean the inner wall of the T-ring 701 and the inner wall of the treatment tank 200. The dust and impurities removed will fall through the gap between the blocking ring 706 and the inner wall of the treatment tank 200 and finally fall into the receiving box 806. After cleaning, the entire treatment tank 200 will be left to stand for a period of time. At this time, the operator can rotate the blocking rod 807 to remove the receiving box 806 from the transfer tank 801. This completes the cleaning of dust and impurities in the treatment tank 200 and facilitates its reuse in the future.
