Description
Technical field
The utility model relates to technical field of motors more particularly to a kind of trace particle feeding devices.
Background technique
In the work experimental glass flume experiment of river, doppler velocimeter utilizes minute impurities in water according to doppler principle
Grain subreflexive ultrasonic signal obtains the flow velocity of water.When impurities in water particle is very few, precise measurement cannot achieve.Therefore
It is frequently necessary to the fine particles such as supplementary model sand in water flow.
It is generally fed by the way of manually toppling over suspension containing trace particle in laboratory at present, thus to data
Continuous-stable acquisition have larger impact.
Utility model content
In view of the above deficiencies, the utility model proposes a kind of trace particle feeding device, which adds with automatic uniform
Add the function of trace particle, without human intervention, the collecting efficiency of doppler velocimeter data can be improved.
In order to achieve the above object, technical solution used by the utility model is as follows: a kind of trace particle feeding device,
For to trace particle is added in the work laboratory sink of river, the downstream fragment position of the sink to have doppler velocimeter, the dress
It sets including stirring pool, water inlet vacuum pump, addition vessel, charging valve, blender, water outlet vacuum pump and isocon；The stirring
Pond is fixedly arranged above addition vessel, addition vessel exit installation charging valve, and the entrance for vacuum pump of intaking stretches to Doppler
In the water flow of current meter upstream position, stirring pool is protruded into the outlet for vacuum pump of intaking, and the blender is fixed in stirring pool, out
The entrance of water vacuum pump protrudes into stirring pool, and the outlet for being discharged vacuum pump is connected with isocon；The isocon is laterally fixed
In sink riverbed bottom surface, and it is in the upstream position of doppler velocimeter.
Further, it is evenly distributed with opening on the isocon, and keeps opening upward perpendicular to sink bottom surface.
The beneficial effects of the utility model are: the utility model is automation equipment, pass through control charging valve goalkeeper charging
Stirring pool is added in trace particle in container, and by intaking, vacuum pump draws water from sink into stirring pool, by blender by water
Suspension is stirred into trace particle, then suspension is imported to the isocon for being fixed on bottom of gullet by water outlet vacuum pump,
There is equally distributed opening on isocon, and keep opening upward perpendicular to sink bottom surface, isocon is added into water flow
Add trace particle, doppler velocimeter more accurately can efficiently measure in the water flow for being added to uniform trace particle.
Water inlet vacuum pump and water outlet vacuum pump realize the water flow closed-loop system between sink and stirring pool, will not additionally introduce flow.
The structure of the utility model is relatively simple, can effectively reduce artificial demand and improve doppler velocimeter in the more pure field of water quality
Service precision under scape.

In figure, stirring pool 1, water inlet vacuum pump 2, addition vessel 3, charging valve 4, blender 5 are discharged vacuum pump 6, water inlet
Conduit 7, water output duct 8, isocon 9, sink 10, doppler velocimeter 11, water flow 12, suspension 13.
Specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model be not limited to
Lower embodiment.
As shown in Figure 1, the utility model provides a kind of trace particle feeding device, it includes stirring pool 1, water inlet vacuum pump
2, addition vessel 3, charging valve 4, blender 5, water outlet vacuum pump 6, penstock 7, water output duct 8 and isocon 9.It is described to stir
It mixes pond 1 and is placed in 10 side of sink, doppler velocimeter 11 is located at the downstream fragment position in sink 10.It is solid above the stirring pool 1
Surely have a funnel-form addition vessel 3,3 exit of addition vessel installation charging valve 4, by charging valve 4 control trace particle into
Enter stirring pool 1.The water inlet vacuum pump 2 is fixed on 1 side of stirring pool, and penstock 7 is deep into 11 upstream of doppler velocimeter
In the water flow 12 of position, the entrance of water inlet vacuum pump 2 is connected with penstock 7, is introduced water flow 12 by water inlet vacuum pump 2
In stirring pool 1.The blender 5 is fixed in stirring pool 1, for water and trace particle to be stirred into suspension 13, it is described go out
Water vacuum pump 6 is fixed on 1 side of stirring pool, and the entrance of water outlet vacuum pump 6 is protruded into suspension 13 by water output duct 8, and water outlet is true
The outlet of sky pump 6 is connected by another water output duct 8 with isocon 9, is extracted into suspension 13 point by being discharged vacuum pump 6
Flow tube 9.The isocon 9 is secured transverse to 10 riverbed bottom surface of sink, and is in 11 upstream position of doppler velocimeter, isocon
On 9 have equally distributed opening, opening in rods arranged in horizontal line on isocon 9, and make opening perpendicular to 10 bottom surface of sink to
On.Charging valve 4 can use and screw valve.Minipump can be used in water inlet vacuum pump 2 and water outlet vacuum pump 6；Water inlet is true
Sky pump 2, water outlet vacuum pump 6 and blender 5 are all controlled by power switch, can automatic running after energization.
The working principle of the utility model is: stirring pool 1 is added in trace particle in addition vessel 3 by rotary feeding valve 4
In, by intaking, vacuum pump 2 is drawn water from sink 10 into stirring pool 1, is stirred into water and trace particle by blender 5 outstanding
Turbid 13, then suspension 13 is imported to the isocon 9 for being fixed on 10 bottom of sink by water outlet vacuum pump 6, it can be to water flow
In uniformly add trace particle, and influence is nearly free from water flow longitudinal direction flow velocity, keeps doppler velocimeter 11 more accurate
Efficiently measure.Water inlet vacuum pump 2 and water outlet vacuum pump 6 realize the closed loop of the water flow between sink 10 and stirring pool 1
System.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
