Description

Technical Field

[0001] The utility model relates to the technical field of bag dust removal, in particular to a novel high-efficiency bag dust removal and ash cleaning device. Background Art

[0002] The bag filter is a dry dust filter 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 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] After long-term use, a lot of dust will adhere to the outer surface of the bag, and the dust needs to be removed. The traditional way of removing dust is generally to knock on the bag, using external force to knock on the bag. Although this dust removal method can knock off the dust, after each cleaning, a lot of small dust will be raised in the entire filter. With the subsequent operation of the filtering mechanism, the dust will adhere to the bag again, and it needs to be cleaned again at the time end with less gaps, and the time interval between cleanings is short.

DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0014] Reference Figure 1-Figure 3As shown, a novel high-efficiency bag dust removal and cleaning device comprises a shell 1, an air inlet 5 is arranged on the left side of the bottom space of the shell 1, an air outlet 7 is connected to the top space of the shell 1, an ash discharge port 12 is arranged on the inner bottom of the shell 1, and sealing valves are installed in the ash discharge port 12, the air inlet 5 and the air outlet 7; it also comprises a filtering mechanism, the filtering mechanism comprises a mounting circular plate 8 horizontally arranged in the shell 1, and a plurality of filter bags 9 are installed on the mounting circular plate 8; it also comprises a shaking mechanism, the shaking mechanism comprises a shaking net 10 horizontally arranged in the shell 1, the upper end of the shaking net 10 is fixedly connected to the lower ends of the plurality of filter bags 9, and a vibration motor 11 is installed at the lower end of the shaking net 10, and mounting cylinders 14 are fixedly connected to the inner walls on both sides of the left and right sides of the shell 1, and each mounting cylinder 14 is provided with A slidable sliding block 15, the upper end of each sliding block 15 is elastically connected to the inner top of the mounting tube 14 through a spring 16, the lower end of each sliding block 15 is fixedly connected to a connecting rod 17, the lower end of each connecting rod 17 is fixedly connected to the upper end of the shaking net 10, and the holes on the shaking net 10 are relatively large; it also includes a collecting mechanism, which is used to collect dust. The collecting mechanism includes a circulating fan 6 installed at the upper end of the shell 1, the air outlet end of the circulating fan 6 extends to the top of the shell 1, and a filter box 2 is fixedly connected to the right side of the shell 1, and the air inlet end of the circulating fan 6 extends to the bottom space of the filter box 2. The top space of the filter box 2 is connected to the bottom space of the shell 1 through a connecting pipe 4, a filter element 13 is installed in the filter box 2, and a sealing door 3 is installed on the front side of the shell 1.

[0015] When cleaning is required, first open the ash discharge port 12, and seal the air inlet 5 and the air outlet 7, then start the vibration motor 11. The start of the vibration motor 11 will cause the shaking net 10 to shake, and the shaking force of the shaking net 10 will be transmitted to the filter bag 9, so that the filter bag 9 will shake and shake off the dust on the filter bag 9. In this process, large particles of agglomerated dust will fall into the ash discharge port 12 and be finally discharged. After a period of time, only a small part of the raised small dust remains in the shell 1. At this time, close the ash discharge port 12 and start the circulating fan 6, which will generate a circulating air flow in the bottom space of the shell 1, the filter box, the circulating fan 6, the top space of the shell 1 and part of the space of the shell 1. The circulating airflow can absorb the raised dust into the filter element 13, and the circulating airflow also has a backblowing effect, which can further improve the dredging effect of the filter bag 9.
