Embodiment
The utility model is further described below in conjunction with the accompanying drawings, but the scope of protection of the utility model is not limited to
It is as described below.
As shown in Figure 1 and 2, a kind of oil grain counter, it includes sample bottle 1, feed tube 2, sample cell 4, liquid back pipe
11st, plunger pump 7, waste collection bottle 8, one end of feed tube 2 are inserted in sample bottle 1, and the other end is connected with one end of sample cell 4,
The other end of sample cell 4 is connected with one end of liquid back pipe 11, in the other end insertion waste collection bottle 8 of liquid back pipe 11, liquid back pipe
Plunger pump is provided between 11 and sample cell 4, the top of sample cell 4 is provided with laser beam emitting device 5, laser beam emitting device 5 and sample
Laser shaping device 10 is set between pond 4, the lower section of sample cell 4 is provided with photoreceiver 6, and photoreceiver 6 is connected with processor 9,
Waveform transverse tube 3 is provided between feed tube 2 and sample cell 4, waveform transverse tube 3 is tubular structure, and upper and lower surface is equipped with wave
Shape is raised, and the projection and the projection of lower surface of upper surface are staggered.
The pitch of described waveform transverse tube 3 and the power match of plunger pump 7.
The groove depth and the ratio of caliber that the adjacent protrusion of described waveform transverse tube 3 is formed are less than or equal to 0.5.
The quantity of the convex outer surfaces of described waveform transverse tube 3 is no less than five.
Described feed tube 2 and the internal diameter of liquid back pipe 11 are identical with the both ends diameter of waveform transverse tube 3.
The course of work of the present utility model is as follows：Plunger pump 7 extracts oil sample from from sample bottle 1, and oil sample is from sample bottle 1
Woven hose 2, waveform transverse tube 3 and sample cell 4 are sequentially entered after extraction, the waveform transverse tube 3 is tubular structure, is set on its tube wall
There is contoured shaped recess, the contoured shaped recess spiral winding is along the length direction spiral extension of waveform transverse tube 3, when band in sample bottle 1
The oil sample of solid particle is extracted after woven hose 2 flows into waveform transverse tube 3, due to the shadow by waveform configuration in waveform transverse tube 3
Ring, the fluid particle speed moved along the tube wall of waveform transverse tube 3 is slower with respect to the flow velocity in the centre of tube wave shape transverse tube 3, and tube wall
Neighbouring fluid particle can move along the contoured shaped recess part of wall to the centre of waveform transverse tube 3, in waveform transverse tube 3
The suction that center portion position fluid is subject to is larger, therefore the fluid translational speed in centre is very fast, in the near-wall of waveform transverse tube 3
Acceleration of the big mass particle obtained in the centre moving process of waveform transverse tube 3 increases, and preferential waveform transverse tube 3 passes through ripple
Shape transverse tube 3, the acceleration that the less particle of quality obtains is smaller, relatively later to pass through the core duct of waveform transverse tube 3, waveform
Oil sample forms spiral forward in transverse tube 3, and using the center of waveform transverse tube 3 as peak flow rate (PFR), pipe outer wall position is lowest speed,
The spiral liquid flow with larger current gradient is formed, in the presence of this liquid stream, oil sample particle gradually collects to the middle part of waveform transverse tube 3
In, tentatively reduce oil sample particle Duplication.Also, due to the waveform transverse tube 3 have be less than and close to 0.5 groove depth internal diameter
Than, be formed the oil sample particulate transportation passage of a very little, oil sample particle during being concentrated to the middle part of waveform transverse tube 3 again
Duplication can be further reduced, so oil sample forms the oil sample particle of one Relatively centralized in the exit of waveform transverse tube 3
Jet, oil sample particle jet enter sample cell 4, and the light beam that the laser beam emitting device 5 on sample cell 4 is launched passes through laser
After the shaping of reshaper 10 inject sample cell 4 in, oil sample particle block light beam and obtained on photoreceiver 6 varying strength and
The pulse signal of frequency, the pulse signal is transferred to the processor 9 being connected on photoreceiver 6, by the data of processor 9
Processing obtains solid particle quantity and the size in oil sample, and final sample is flowed into waste collection bottle 8, completes the detection of oil sample.
