Abstract
An air exhaust device includes a gas-collecting hood and a plurality of pipelines, wherein the pipelines are connected through movable joints sequentially; an air inlet of the first pipeline is connected with an air outlet of the gas-collecting hood, and an air outlet of the last pipeline is an air outlet of the air exhaust device; a detachable screen stencil is mounted inside the first pipeline; and the mesh size of the screen stencil is 10-80. Compared with the prior art, the device is convenient to use and simple to machine, and has a better exhausting effect as an overcurrent is provided.
Description
Technical field
The utility model belongs to the experimental provision in the fields such as biochemistry, pharmacy, specifically a kind of air exhausting device.
Background technology
For preventing the nuisance that equipment produces in process of production or the operation time of feeding intake produces workshop air and pollutes, often on the spot nuisance is captured by hood or inlet scoop.But existing capturing device usage space is restricted, and the pollutant such as dust also easily causes certain infringement to blower fan, can not realize well its usefulness fully.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of air exhausting device, comprise gas skirt and Duo Gen pipeline, each root pipeline connects by turning joint successively, the air inlet of first pipeline connects the air outlet of described gas skirt, and the air outlet of last root pipeline is the air outlet of this air exhausting device; In first pipeline, detachable screen cloth is housed; The order number of screen cloth is 10 orders～80 orders.
The material of screen cloth is copper, copper alloy, receive synthetic fibre, polyamide fibre or terylene.Gas skirt be shaped as arch or taper.The quantity of pipeline is 2～10 roots.Be connected with volume adjusting apparatus between described first pipeline and the gas skirt.The material of described pipeline, joint and gas skirt is polypropylene.Air outlet position place at described last root pipeline is connected with the rotation telescoping catheter, and that rotates telescoping catheter is not connected the exhaust outlet that an end consists of this air exhausting device with pipeline.
Compared with prior art, this device is easy to use, and processing is simple, and overcurrent is arranged one, the air draft better effects if.
Description of drawings
Fig. 1 is schematic flow sheet of the present utility model;
Among the figure: the 1-exhaust outlet; The 2-pipeline; 3-rotates telescoping catheter; 4-turning joint; The 5-gas skirt; The 6-screen cloth; The 7-volume adjusting apparatus.
The specific embodiment
Below by the specific embodiment, the technical solution of the utility model is described in further detail.
A kind of air exhausting device comprises gas skirt and Duo Gen pipeline, and each root pipeline connects by turning joint successively, and the air inlet of first pipeline connects the air outlet of described gas skirt, and the air outlet of last root pipeline is the air outlet of this air exhausting device; In first pipeline, detachable screen cloth is housed; The order number of screen cloth is 10 orders～80 orders.
