The present utility model provides an embodiment:

as shown in fig. 1, the dust settling tank convenient for collecting dust samples comprises a cylindrical part 1, a conical part 2 and a bracket 3, wherein the cylindrical part 1 is positioned above the conical part 2 and is in arc transition connection with the conical part 2, a horn-shaped water inlet pipe 4 is arranged at the outer wall of the cylindrical part 1, the water inlet pipe 4 is positioned above the bracket 3, the water inlet pipe 4 is horizontally arranged, the inner diameter of the water inlet pipe 4 gradually contracts along the direction far away from the water inlet end of the water inlet pipe and is in arc transition with the communication part of the cylindrical part 1, so that water flow enters the cylindrical part 1 along the tangential direction of the communication part, a sealing cover 1.1 for preventing water flow from splashing is movably arranged at the upper end of the cylindrical part 1, a flow guide pipe 5 is communicated at the lower end of the conical part 2, and the on-off of the flow guide pipe 5 is controlled through a valve 6; the conical part 2 is clamped on the bracket 3, a tray 3.1 for placing the container 7 is arranged at the lower end of the bracket 3, and a baffle ring 3.11 for preventing the container 7 from shaking is arranged on the tray 3.1.

In this embodiment, a horizontal stop collar 3.2 is fixed at the middle upper part of the bracket 3, and the middle part of the conical part 2 is clamped on the stop collar 3.2. The upper end and the middle part of the bracket 3 are both provided with reinforcing rings 3.3, the two reinforcing rings 3.3 are connected through two vertical ribs 3.4, the limiting ring 3.2 is positioned between the two reinforcing rings 3.3 and fixed on the vertical ribs 3.4, and the reinforcing rings 3.3 in the middle part are connected with the tray 3.1 through one vertical rib 3.4.

The specific operation steps are as follows:

after the dust settling tank has been transferred to the analysis chamber, a sealing cap 1.1 is mounted on the upper end of the cylindrical part 1. The sample collection container 7 is then placed on the tray 3.1 directly below the draft tube 5 and the valve 6 is opened. The water inlet pipe 4 is connected with a water source, and clean water enters the dust settling tank from the water inlet pipe 4 at a high speed along the tangential direction.
