Description

Technical Field

[0001] This utility model relates to the field of industrial dust removal equipment technology, specifically to an online detection mechanism for filter bag damage in dust collectors. Background Technology

[0002] A bag filter is a dust collection device that filters air pollutants from industrial processes using filter bags or pleated filter bags, capturing harmful particles and dust, and discharging clean air. A differential pressure sensor is used to measure the pressure difference across the filter bag. When the filter bag is damaged, gas enters the dust collector through the damaged area, causing a change in pressure across the filter bag. By measuring this change in pressure difference, the differential pressure sensor can accurately determine whether the filter bag is damaged.

[0003] Existing differential pressure sensor probes generally lack dustproof functionality and cannot achieve real-time self-cleaning. During dust removal, differential pressure sensor probes are easily covered by dust, leading to inaccurate measurements. Manual cleaning and maintenance are required, affecting the continuous operation of the equipment. Therefore, there is an urgent need for a filter bag damage detection mechanism with dustproof functionality. Utility Model Content

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.

[0024] Please see Figures 1-6 The dust collector filter bag damage online detection mechanism includes a differential pressure measuring instrument body 1. Flexible hoses 4 are installed on both sides of the bottom of the differential pressure measuring instrument body 1. A pressure tap 5 is fixedly connected to one end of each hose 4. A cylinder cover 6 is fixedly connected to one side of each pressure tap 5 by screws. By fixing the pressure tap 5 to the cylinder cover 6, the pressure tap 5 can be connected to the differential pressure measuring instrument body 1 through the hoses 4. A pressure tapping cylinder 9 is fixed to one side of the cylinder cover 6. By fixing the two pressure tapping cylinders 9 to the high-pressure end and low-pressure end of the dust collector respectively, the differential pressure measuring instrument... The main body 1 can monitor the pressure difference through the pressure tapping nozzle 5. The pressure tapping cylinder 9 is equipped with a dustproof component 15 to filter dust. The dustproof component 15 can filter dust in the airflow, preventing dust from reaching the pressure tapping nozzle 5 and covering its surface. A dust cleaning component 16 is provided on one side of the dustproof component 15 to clean it. The dust cleaning component 16 can vibrate and clean the dustproof component 15, realizing the rapid removal of dust and preventing dust from clogging the dustproof component 15.

[0025] In this embodiment, preferably, the dustproof component 15 includes a first filter cup 1501, a retaining ring 1502 fixedly provided on one side of the first filter cup 1501, an inner ring 1503 fixedly provided on the inner wall of the retaining ring 1502, a second filter cup 1504 fixedly provided on one side of the inner ring 1503, the second filter cup 1504 being located inside the first filter cup 1501, the filter holes of the second filter cup 1504 being smaller than the filter holes of the first filter cup 1501, a support ring 12 fixedly provided inside the pressure tapping cylinder 9, a groove 13 being provided on one side of the support ring 12, the groove 13 being engaged internally. A rubber ring 14 is attached, and one side of the retaining ring 1502 is fixedly connected to one side of the support ring 12 by screws. The retaining ring 1502 can fix the filter cup 1501 to the support ring 12. The rubber ring 14 can seal the space between the retaining ring 1502 and the support ring 12. The filter cup 1501 can provide support for the filter cup 2 1504 through the inner ring 1503. Since the filter holes of the filter cup 2 1504 are smaller than those of the filter cup 1501, the filter cup 2 1504 and the filter cup 1501 can achieve dual filtration of dust.

[0026] In this embodiment, preferably, the dust removal assembly 16 includes a mounting plate 1601 and a vibration motor 1603. One side of the mounting plate 1601 is fixedly connected to one side of the retaining ring 1502. One side of the vibration motor 1603 is fixedly provided with a mounting base 1602. One side of the mounting base 1602 is fixedly connected to the middle of the other side of the mounting plate 1601 by screws. The vibration motor 1603 vibrates the mounting plate 1601, and the mounting plate 1601 can transmit the vibration force to the second filter cup 1504 and the first filter cup 1501, so as to clean the second filter cup 1504 and the first filter cup 1501.

[0027] In this embodiment, preferably, connectors 3 for installing hoses 4 are fixedly provided on both sides of the bottom end of the differential pressure measuring instrument body 1. Ear plates 2 are fixedly provided on the top and bottom of both sides of the differential pressure measuring instrument body 1. Mounting holes are opened on the surface of the ear plates 2. The hoses 4 can be installed through the connectors 3, and the differential pressure measuring instrument body 1 can be fixedly installed on the dust collector through the ear plates 2.

[0028] In this embodiment, preferably, a connecting ring 7 is fixedly provided on one side of the pressure tapping cylinder 9, and a sealing gasket 8 is engaged with one side of the connecting ring 7. The cylinder cover 6 is fixedly connected to one side of the connecting ring 7 by bolts. An installation ring 10 is fixedly provided on the other side of the pressure tapping cylinder 9, and a sealing ring 11 is engaged with one side of the installation ring 10. Several positioning holes are opened on the surface of the installation ring 10. A through hole 17 is opened in the middle of the cylinder cover 6 to be inserted and connected to the pressure tapping nozzle 5. A sealing gasket 2 18 is engaged with one side of the through hole 17. The cylinder cover 6 can be fixed by the connecting ring 7, and the pressure tapping cylinder 9 can be installed on the dust collector by the installation ring 10. The sealing gasket 8 and the sealing gasket 2 18 can play a sealing role, and can absorb kinetic energy and provide buffering and shock absorption for the pressure tapping nozzle 5, reducing the vibration transmitted from the dust removal component 16 to the pressure tapping nozzle 5.

[0029] In use, the operator first fixes the differential pressure measuring instrument body 1 on the dust collector using the ear plate 2, then fixes the two pressure tapping cylinders 9 to the high-pressure end and low-pressure end of the dust collector respectively using the mounting ring 10. Then, the hose 4 is connected to the differential pressure measuring instrument body 1 through the connector 3. Then, one end of the pressure tapping nozzle 5 is passed through the through hole 17 and fixed to the cylinder cover 6. The differential pressure measuring instrument body 1 can monitor the pressure difference between the high-pressure end and the low-pressure end in the dust collector through the pressure tapping nozzle 5. When the filter bag is damaged, the pressure difference changes, thus enabling online detection of filter bag damage.

[0030] During the testing process, the rubber ring 14 can seal the gap between the retaining ring 1502 and the support ring 12 of the dustproof component 15. The filter cup 1501 can provide support for the filter cup 2 1504 through the inner ring 1503. Since the filter holes of the filter cup 2 1504 are smaller than those of the filter cup 1501, the filter cup 2 1504 and the filter cup 1501 can achieve dual filtration of dust, preventing dust from reaching the pressure tap 5 and covering the surface of the pressure tap 5, thereby ensuring the testing accuracy.

[0031] When it is necessary to clean the filter cup 2 1504 and filter cup 1 1501, the vibration motor 1603 of the cleaning assembly 16 vibrates the mounting plate 1601. The mounting plate 1601 can transmit the vibration force to the filter cup 2 1504 and filter cup 1 1501, thereby cleaning the filter cup 2 1504 and filter cup 1 1501. This achieves rapid dust removal and avoids dust clogging the filter holes of the filter cup 2 1504 and filter cup 1 1501. There is no need to stop the machine for cleaning, which can ensure the continuous operation of the equipment. During the cleaning process, the sealing gasket 1 8 and sealing gasket 2 18 can absorb kinetic energy and provide buffering and shock absorption for the pressure tap 5, reducing the vibration transmitted to the pressure tap 5. In addition, the sealing gasket 1 8 and sealing gasket 2 18 can play a sealing role.
