As shown in fig. 1 to 2, a large particle dust collecting apparatus according to an embodiment of the present utility model includes: a main pipeline 1, a filter screen 2, a dust exhaust pipe 3 and a filter screen cleaning component 4. The filter screen 2 is arranged at one end of the main pipeline 1, into which dust enters, and is used for filtering large-particle dust. One end of the dust discharging pipe 3 is connected with the filter screen 2 for discharging large particle dust. The filter screen cleaning component 4 is arranged below the filter screen 2 and is used for cleaning large-particle dust adsorbed on the filter screen 2.

The large particle dust collecting device will be equipped with a powerful motor during collection of the large particle dust to provide sufficient suction of the main pipe 1. In this process, the filter screen 2 filters large particle dust so that it cannot pass through the filter screen 2, and air flow and small particle dust can pass through. The filter screen 2 is connected with one end of the dust exhaust pipe 3, and the filtered large-particle dust is discharged in time. Since suction is continuously present in the main pipe 1, a large amount of large particle dust is adsorbed on the screen 2. In order to discharge these large particle dusts in time, a screen cleaning assembly 4 is provided below the screen 2. The filter screen cleaning assembly 4 can clean large particle dust adsorbed on the filter screen 2 and discharge the large particle dust through the dust discharge pipe 3.

In one embodiment, the filter screen 2 is a horn filter screen 2, and the diameter of the filter screen 2 gradually decreases along the direction of dust flow. The filter screen 2 is designed in a horn shape, so that the filter screen 2 has the largest contact area with large particle dust in the same projection area, and more large particle dust can be filtered in the same time. In addition, the maximum diameter of the filter screen 2 is equal to the diameter of the main pipeline 1, so that the projections of the filter screen 2 and the main pipeline 1 in the axial direction of the main pipeline 1 are completely overlapped, a gap is not reserved between the filter screen 2 and the main pipeline 1, and large particle dust can be filtered.

In one embodiment, the pore size on the screen 2 is between 70 μm and 100 μm. So set up, filter screen 2 can make granule dust and gaseous smooth through filter screen 2 again in effective filtration large granule dust.

One end of the dust exhaust pipe 3 is arranged in the main pipeline 1 and is connected with the filter screen 2; the other end of the dust discharging pipe 3 passes through the pipe wall of the main pipe 1 and is arranged outside the main pipe 1 so as to timely discharge the collected large particle dust. In order to avoid that large-particle dust is directly discharged into the environment, the dust collecting bag 31 is arranged at one end of the dust discharging pipe 3 outside the main pipe 1, and can collect the large-particle dust.

In one embodiment, as shown in fig. 2, the screen cleaning assembly 4 includes an annular frame 41, a mount 42, a rotating shaft 43, a scraper 44, and a fan blade wheel 45. The annular frame 41 is disposed below the screen 2, and is connected to the screen 2 and fixed in the main pipe 1. The fixing frame 42 is disposed in the annular frame 41 and connected to the annular frame 41. The rotation shaft 43 is provided at the center of the holder 42, and is coaxially provided with the holder 42.

The fan impeller 45 is provided at the other end of the rotation shaft 43. In addition, the annular frame 41 is equal with the diameter of the main pipeline 1, on the one hand, for matching with the maximum diameter of the filter screen 2, and on the other hand, for matching with the diameter of the main pipeline 1 for installation, so that the arrangement can avoid that gaps are reserved among the filter screen 2, the annular frame 41 and the main pipeline 1, and large particle dust passes through the gaps, thereby influencing the filtering effect of the filter screen 2.

Wherein, scraper 44 and rotation axis 43 fixed connection, fan impeller 45 and rotation axis 43 also fixed connection, fan impeller 45 passes through rotation axis 43 and drives scraper 44 joint motion. As the air flow passes through the main conduit 1, the fan impeller 45 is driven by the air flow to start rotating. The scraper 44 is connected to the rotation shaft 43 so that when the fan impeller 45 rotates, the scraper 44 rotates together and moves along the surface of the screen 2, thereby scraping the large particle dust adsorbed on the screen 2 and discharging the same through the dust discharge pipe 3.

Specifically, a connecting rod 46 is provided between the squeegee 44 and the rotation shaft 43, one end of the connecting rod 46 is connected to the rotation shaft 43, the other end is connected to the squeegee 44, and the connecting rod 46 is provided perpendicular to the rotation shaft 43. The angle between the scraping blade and the connecting rod 46 can be adjusted by the arrangement, so that the surface of the filter screen 2 is more fitted, and the scraping effect of the scraping blade 44 is better.

According to the large-particle dust treatment device, the filter screen 2 is arranged, so that the large-particle dust can be filtered, and meanwhile, the smooth passing of gas can be ensured. The dust exhaust pipe 3 can timely exhaust the large-particle dust filtered by the filter screen 2. The filter screen cleaning component 4 can timely clean the large-particle dust adsorbed on the filter screen 2 while filtering the large-particle dust without affecting the filter screen 2, so that the filter screen 2 is prevented from being blocked.
