Abstract
The invention relates to the field of air dispersing devices, and discloses an air dispersing ring, which comprises a ring body; an annular air path is formed in the wall of the ring body; a plurality of air outlets communicated with the air passage are formed in the inner wall of the ring body; an air inlet communicated with the air passage is formed in the outer wall of the ring body; the air inlet is externally connected with an air source. The air outlet is a cylindrical hole which is obliquely arranged. The included angle between the axis of the air outlet and the vertical surface is 50-70 degrees. The included angle of the gas outlet axis and the radius of the ring body passing through the axis is 10-15 degrees. The air supply blows to the air inlet, and the gas circuit disperses the air to each gas outlet, and the gas outlet is with air blowout, and a plurality of gas outlet spun air cover sampler outer pipe wall is whole, blows off the solid powder of adhesion on the outer pipe wall, causes the sample to pollute when preventing that the sampler from reusing.
Description
Technical Field
The invention relates to an air dispersing device, in particular to an air dispersing ring for a powder sampler.
Background
The powder sampler is used for sampling solid powder, and current sampler is mostly the tubulose, and solid powder can glue on sampler outer pipe wall, if not in time clearance, can remain on the pipe wall gluing solid powder on the sampler pipe wall, causes the sample to pollute when practical this sampler once more easily.
Disclosure of Invention
The invention aims to provide an air dispersing ring for a powder sampler, which blows off solid powder on the wall of a sampler tube by using air.
The technical scheme adopted by the invention for solving the technical problems is as follows: an air dispersion ring comprising a ring body; an annular air path is formed in the wall of the ring body; a plurality of air outlets communicated with the air passage are formed in the inner wall of the ring body; an air inlet communicated with the air passage is formed in the outer wall of the ring body; the air inlet is externally connected with an air source. The air supply blows to the air inlet, and the gas circuit disperses the air to each gas outlet, and the gas outlet is with air blowout, and a plurality of gas outlet spun air cover sampler outer pipe wall is whole, blows off the solid powder of adhesion on the outer pipe wall, causes the sample to pollute when preventing that the sampler from reusing.
Further, the method comprises the following steps: the air outlet is a cylindrical hole which is obliquely arranged.
Further, the method comprises the following steps: the included angle between the axis of the air outlet and the vertical surface is 50-70 degrees.
Further, the method comprises the following steps: the included angle of the gas outlet axis and the radius of the ring body passing through the axis is 10-15 degrees. The gas outlet is set as an inclined hole, powder adhered to the outer tube wall of the sampler is blown off at a certain inclined angle, the blown-off powder can be concentrated on one side, and the blown-off powder is prevented from being adhered to the cleaned tube wall again.

FIG. 2 is a top view of the air ring air flow.
Labeled as: 100. a ring body; 110. a gas circuit; 111. an air inlet; 112. an air outlet; 120. and (4) a gas source.
Detailed Description
The invention is further described with reference to the following figures and detailed description.
As shown in fig. 1, an air dispersing ring for a powder sampler comprises a ring body 100; an annular air passage 110 is formed in the wall of the ring body 100; a plurality of air outlets 112 communicated with the air passage 110 are formed on the inner wall of the ring body 100; an air inlet 111 communicated with the air passage 110 is formed in the outer wall of the ring body 100; the air inlet 111 is externally connected with an air source 120. The gas outlets 112 are uniformly arranged along the inner wall of the ring body 100, the gas flow direction of the high-pressure gas sprayed from the gas outlets 112 is shown by the dotted line in fig. 1 and fig. 2, a circle is formed in the middle of all the gas flow directions, and the diameter of the circle is smaller than that of the powder sampler, so that the high-pressure gas flow can cover the whole outer wall of the sampler, and powder is prevented from being adhered to the pipe wall.
On the basis of the above, as shown in fig. 1, the air outlet 112 is a cylindrical hole which is obliquely arranged.
On the basis of the above, as shown in fig. 1, the included angle between the axis of the air outlet 112 and the vertical plane is 50-70 °. The angle may be 50 °, 60 ° or 70 °, in this example the axis of the air outlet 112 is at an angle of 60 ° to the vertical.
On the basis of the above, as shown in fig. 1, the included angle between the axis of the air outlet 112 and the radius of the ring body 100 passing through the axis is 10-15 °. The angle may be 10 °, 12 °, 13 ° or 15 °, in this example 12 °.
When the gas source 120 is actually used, high-pressure gas is injected into the gas inlet 111 and is sprayed out through the gas outlet 112; pass the sampler and take a sample behind the ring body 100, after the sample, when the sampler was through ring body 100, the solid powder of adhesion can be blown off by high-pressure draught on the sampler outer wall, guarantees the cleanness of sampler outer wall.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
