Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a bag dust collector which is easy to clean. Background Art

[0002] The bag dust collector is a dry dust filtering device, which 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 dust collector, the large particles and high specific gravity 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. The high dust removal efficiency of the bag dust collector is inseparable from its dust removal mechanism. The dust-containing gas is passed through the lower air intake duct of the dust collector. When entering the ash hopper through the guide plate, due to the collision of the guide plate and the reduction of gas velocity, coarse dust will fall into the ash hopper, and the remaining fine dust particles will enter the filter bag chamber with the gas. Due to the inertia, diffusion, barrier, hooking, static electricity and other effects of the filter material fibers and fabrics, the dust is retained in the filter bag, and the purified gas escapes from the bag and is discharged through the exhaust pipe. The accumulated dust on the filter bag is removed by gas backwashing, and the removed dust goes down to the ash hopper and is discharged to the ash conveying device through the double-layer ash unloading valve. The accumulated dust on the filter bag can also be removed by blowing pulse airflow, thereby achieving the purpose of cleaning.

[0003] However, when the existing bag-type dust collector is used for a long time, dust and impurities are easily attached to the inner wall of the bag-type dust collector, and the staff needs to go deep into the inner wall of the bag-type dust collector from the ash outlet end to clean it. The steps for cleaning the inner wall of the bag-type dust collector are relatively complicated, and the manual cleaning method increases the workload of the staff. At the same time, the manual cleaning method will also cause dust overflow when the staff cleans the bag-type dust collector, causing the staff to inhale the dust into the body, and long-term inhalation will cause damage to the lungs and respiratory tract of the staff.

[0078] The upper end of the dust collecting funnel 22 is fixedly passed through the lower wall of the dust collector housing 1 , so as to facilitate the discharge of impurities in the dust collector housing 1 .

[0079] Working principle: The staff first connects the external gas to be dusted with the air inlet, and at the same time, the staff starts the exhaust fan 14, which can pump the gas in the dust collector housing 1, so that the gas entering the air inlet rises. At this time, the dust bag 13 adsorbs and removes dust, and the dust-removed gas is discharged to the outside by the exhaust fan 14. After the dust removal is completed, the staff starts the pulse valve 20, which can make the gas in the air bag 18 enter the venturi tube 16 through the connecting pipe 19 and the air inlet pipe 15, and then spray out from the air outlet 17, which can remove the dust attached to the surface of the dust bag 13. The dust and impurities are blown away and cleaned. At this time, the staff starts the three-phase motor 9. The rotation of the output end of the three-phase motor 9 can drive the input end of the reducer 8 to rotate. The reducer 8 can reduce the speed input by the three-phase motor 9 and drive a screw 3 to rotate. At this time, under the action of a pair of sprockets 6 and chains 7, another screw 3 can be rotated at the same time. At this time, the rotation of a pair of screws 3 can drive the square frame 4 to descend, so that the scraper 5 scrapes the inner wall surface of the dust collector housing 1 to scrape off the dust and impurities attached to it. The fallen dust and impurities are discharged to the outside by the dust collecting funnel, which brings convenience to people.
