Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a feed pipe opening and a bag dust collector. Background Art

[0002] The bag filter is a dry dust filter. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag filter, the large particles and heavy dust settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.

[0003] A Chinese patent with authorization announcement number CN210645535U discloses an air inlet duct for a bag dust collector and a bag dust collector thereof, including an air inlet duct, wherein the air inlet duct is provided with a first air inlet and a second air inlet, the first air inlet is provided with a first screen, and the second air inlet is provided with a wind shield and a screen, which can effectively relieve wind pressure, prevent large particles of dust from directly blowing the dust bag, effectively prevent the dust bag from being scratched, and extend the service life of the dust bag.

[0004] However, its disadvantage is that in humid weather, the dust-laden gas entering the device will have a certain humidity, and will clump when filtered in the bag dust collector, affecting the filtering effect of the device. Most of the large dust particles accumulate inside the air inlet pipe, making it inconvenient to clean. Utility Model Content

[0011] Preferably, the connecting pipe is a horizontal cylindrical pipe, which is fixedly connected to the feed pipe.

[0012] A bag dust collector comprises the above-mentioned feed pipe opening.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the dust-laden air passes through the first filter screen and the dehumidification block to filter out large particles of dust and moisture, and then enters the box through the first feed port and the second feed port for dust removal, and is discharged from the discharge port after completion, thereby reducing the agglomeration phenomenon in the device, enhancing the filtering effect, and increasing the service life of the device, preventing large particles of dust from accumulating in large quantities inside the feed pipe on the dust removal bag, and facilitating cleaning.
