Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a pulse bag filter with a dust collection mechanism. Background Technique

[0002] The pulse bag filter is a filter type dust removal equipment based on the filtration principle. It uses organic fiber or inorganic fiber filter cloth to filter the dust in the gas. Compressed air is ejected from the nozzle, causing the filter bag to suddenly expand. Under the action of the reverse air flow, the dust attached to the surface of the filter bag quickly detaches from the filter bag and falls into the ash hopper. There are still certain defects in the existing pulse bag filters during use, such as;

[0003] The existing pulse bag filters usually directly discharge the dust from the ash hopper below. Dust is easily generated during discharge, polluting the environment. Most of them cannot suppress dust for collection. And when replacing the filter bags of the existing pulse bag filters, it is impossible to observe whether each group of filter bags needs to be replaced. When replacing, it is necessary to disassemble the ejection pipe above the filter bag to remove the filter bag for replacement, which is rather troublesome. Content of the Utility Model

The rotary nozzle 509 is connected through the inner wall above the cover 505.

[0027] During specific implementation, the diversion hopper 501 is used to divert the dust. Open the valve at the bottom of the dust collector box body 1, and then start the driving motor 502 to drive the spiral plate 503 to rotate on the support plate 504, clean the inner wall of the dust collector box body 1, and at the same time stir the accumulated dust and discharge it into the trolley 506 inside the cover 505.

The dust is collected in the trolley 506, and the trolley 506 is pushed out for dumping, so that the pulse bag filter can collect dust.

[0028] Refer to Figure 1 , Figure 2 , Figure 4 andFigure 5 It can be seen that the dust removal mechanism 9 includes: a Y motor 901, a Y threaded rod 902, a first slider 903, an X slide bar 904, a second slider 905, a Y slide bar 906, an X motor 907, an X threaded rod 908, a connection plate 909, a spray pipe 910, a hose 911, a resistive film pressure sensor 912, and a controller 913.

The Y threaded rod 902 is rotationally connected to the upper surface of the hollow plate 2 through a vertical plate. A first slider 903 is threadedly connected to the Y threaded rod 902.

The connection plate 909 is slidably connected to the X slide bar 904. A spray pipe 910 is penetrated and installed in the connection plate 909. A hose 911 is connected above the spray pipe 910.

The controller 913 can be operated to start the Y motor 901 to drive the Y threaded rod 902 to rotate. The Y threaded rod 902 drives the first slider 903 to drive the second slider 905 to slide along the second slider 905.

[0030] In summary: When using the pulse bag filter with a dust collection mechanism, first, connect the pulse bag filter to the space to be dusted with a pipeline. Start the exhaust fan 10 to discharge the air in the dust collector box 1 and suck the dusty air into the dust collector box 1. The heavier dust particles settle naturally, and the smaller dust particles are filtered by the dust removal cloth bag 3 and adsorbed on the surface of the dust removal cloth bag 3. The air filtered by the dust removal cloth bag 3 enters the chamber above the hollow plate 2 and is discharged from the exhaust fan 10. Weigh the dust removal cloth bag 3 and the framework 4 together through the resistive film pressure sensor 912. If the weight exceeds the threshold, activate the Y motor 901 and the X motor 907 to move the nozzle 910 above the dust removal cloth bag 3. The compressor 6 compresses the air, opens the solenoid valve 7 for release, and the high-pressure air is ejected from the nozzle 910 through the air pipe 8 and the hose 911. The high-pressure air flow impacts the dust removal cloth bag 3 to shake off the dust on the dust removal cloth bag 3. If the weight of the dust removal cloth bag 3 is still abnormal, open the cover plate above the dust collector box 1, pull out the framework 4 from the dust removal cloth bag 3, and replace the dust removal cloth bag 3 when pulling it out. After long-term use, connect a water pipe to the water source, start the water pump 507 to drive the rotating spray head 509 to rotate and spray, open the valve at the bottom of the dust collector box 1 and start the drive motor 502 to discharge the dust into the trolley 506. The water mist sprayed by the rotating spray head 509 quickly settles the raised dust, collects the dust in the trolley 506, and then push the trolley 506 away to dump it. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
