Abstract

The utility model discloses a dust collector. The utility model comprises a dust storing bottle, a dust collecting pipe, an exhaust pipe, a wind direction plate, a baffle plate and a bracket; the dust collecting pipe is divided into a vertical dust collecting pipe (1) and a horizontal collecting pipe (2); the inner of the dust storing bottle (3) is provided with the baffle plate (4) and the exhaust pipe (8); the bracket (10) comprises a tray (101), a rotary shaft (103) and a base (104). The utility model can simultaneously collect dust dropped vertically and horizontally, the dust is not easily blown by the wind, and therefore, the utility model is suitable for field observation in fixed points.

Description

Dust collector

The utility model relates to a kind of instrument that is used for gathering the air-flow dust.Specifically, relate to a kind of instrument that can gather dust the air-flow from vertical and horizontal both direction.

In order effectively to prevent and treat the sandstorm disaster, often need to gather dust in the air-flow, and then infer the source and the intensity of sandstorm by analyzing dust material composition and chemical property.It is comparatively simple and crude to gather in the air-flow the employed device of dust in the past, normally a kind of normal bottles or basin, not only can only collect the dust that lands on the vertical direction, can't gather the dust of horizontal motion, and because bottle or basin are uncovered, thereby the dust of having collected is also often further blown away.

The purpose of this utility model provides a kind ofly both can gather the dust that lands on the vertical direction, also can gather the dust that moves on the horizontal direction, and the dust of having collected simultaneously also is difficult for the dust collector that is blown away.

The utility model comprises dust storage bottle, dust collection tube, gas outlet, wind direction board and support, and its structure is that vertical dust collection tube and horizontal dust collection tube are set on dust storage bottle, and is fixed on the big bottle stopper, stretches in the dust storage bottle, is provided with dividing plate in the dust storage bottle.Fix a wind direction board on the vertical dust collection tube.The big bottle stopper of dust storage bottle is provided with gas outlet.Being provided with an osculum and available little bottle stopper at the bottom of the dust storage bottle wall clogs.Dust storage bottle is fixed on the support of band pallet, rotating shaft and a base, on bracket tray is fixed at the bottom of the dust storage bottle by screw.

After adopting said structure, dust collector can be gathered the dust that lands from dust that moves on the horizontal direction and the vertical direction respectively, but thereby and the rotation of the pipe box haul on the horizontal direction collect the dust of different azimuth.The dust storage bottle plug closes, and be provided with special gas outlet, the dust of having collected is not just blown away by wind.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the cut-open view of the utility model dust collector.

Among the figure, the vertical dust collection tube of 1--, the import of the vertical dust collection tube of 11--, the vertical dust collection tube outlet of 12--, the horizontal dust collection tube of 2--, the import of the horizontal dust collection tube of 21--, the horizontal dust collection tube outlet of 22--, the 3--dust storage bottle is at the bottom of the 31--dust storage bottle, 32--dust storage bottle wall, 4--dividing plate, 5--water, the 51--water surface, 6--wind direction board, the big bottle stopper of 7--, the 8--gas outlet, 81--vent port, the last air admission hole of 82--, air admission hole under the 83--, the 9--osculum, the little bottle stopper of 91--, 10--support, the 101--bracket tray, the 102--screw, 103--rotating shaft, 104--base.

As shown in Figure 1, a certain amount of water is injected in the dust import 11 from vertical dust collection tube 1 earlier during use, and vertical dust collection tube 1 is fixed on the big bottle stopper 7, and passes big bottle stopper 7 and stretch in the dust storage bottle 3, its dust import 11 vertically upward, its dust outlet 12 is passed dividing plate 4 and is immersed in the water 5.Horizontal dust collection tube 2 is fixed on the big bottle stopper 7, and passes big bottle stopper 7 and stretch into dividing plate 4 tops in the dust storage bottle 3, and its dust import 21 is towards level, and its dust outlet 22 vertically downward.Dust storage bottle 3 is fixed on the bracket tray 101.Dividing plate 4 is combined closely with dust storage bottle 3 inwalls, is connected as a single entity, and does not interspace between the two.Water 5 is stored at the bottom of dividing plate 4 and the dust storage bottle between 31, leaves the gap between the water surface 51 and the dividing plate 4.Wind direction board 6 is fixed on the vertical dust collection tube 1.Gas outlet 8 is fixed on big bottle stopper 7 and the dividing plate 4, and its vent port 81 is towards level, and with the dust import 21 of horizontal dust collection tube 2 towards opposite; Between the dividing plate 4 and big bottle stopper 7 of air admission hole 82 in dust storage bottle 3, air admission hole 83 is positioned on the dividing plate 4 under it on it.Osculum 9 be positioned at the bottom of the dust storage bottle 31 with the transition position of dust storage bottle wall 32.Support 10 is positioned at the bottom of dust storage bottle 3, and bracket tray 101 can be fixed at the bottom of the dust storage bottle on 31 by screw 102, but rack shaft 103 box haul plates 6 rotate together, the bottom is a bracket base 104.

Then dust collector is placed on a certain height and bracket base 104 can be carried out the dust collection after fixing.After the dust collection finishes, the water 5 in the dust storage bottle 3 is poured in the vessel into the dust that the oven dry back just can obtain gathering on the vertical direction from osculum 9; Big bottle stopper 7 is opened, poured out the dust that the dust that gathers on dust storage bottle 3 internal partitions 4 can obtain to gather on the horizontal direction.Also a plurality of dust collectors can be placed on the differing heights during use, gather the dust on the differing heights simultaneously.The utility model is convenient to open-air ocean weather station observation especially.
