The content of the invention
For solve above-mentioned prior art manual sampling there is human error, sampling frequency be not fixed, sampling process not
Stablize, can not real time sample the problems such as, the utility model provides a kind of online secondary sample system of powder, can take in real time
Sample improves sampling precision and efficiency, reduces human error.
Technical solution provided by the utility model is：A kind of online secondary sample system of powder, including screwed sampler, two
Secondary sampling below atmospheric pressure pump and tremie pipe, screwed sampler have feed opening, it is characterised in that：Feed opening connects tremie pipe, tremie pipe
Cross-sectional direction sealing is built-in with the secondary sampling below atmospheric pressure pump, and secondary sampling below atmospheric pressure pump is equipped with material receiving port, secondary sampling below atmospheric pressure
The one side of pump is equipped with air inlet, opposite opposite side is equipped with discharge port.
Further, for the ease of adjust sampling amount number, the size of the material receiving port is adjustable.
Further, for the ease of receiving the material to fall, sampling process is made more to stablize, the material receiving port is located at blanking
The center of pipeline internal diameter, face tremie pipe cavity top.
Further, the whereabouts of remaining powder, the tremie pipe are located at secondary sampling below atmospheric pressure after being sampled for the ease of control
The part for pumping lower section is flexible.
Further, for the ease of the remaining powder of recycling, the one end of the tremie pipe away from feed opening is placed in powder container
In.
The beneficial effects of the utility model are：The utility model as power source, is not required to by compressed air in sampling process
Very important person participates in.
During sampling, one end of the screwed sampler and tremie pipe of powder pipe and the utility model need to only be connected, pass through control
The start and stop of compressed air processed and time, with regard to automatically continuously uniform sampling effect can be reached.A small amount of sample is taken just to meet detection
It returns in powder pipe, powder material will not be caused to waste it is required that most of powder provides tremie pipe.
The utility model is simple in structure, at low cost, stable, can greatly improve sampling precision and efficiency.
Description of the drawings
Fig. 1 is a kind of structure diagram of the online secondary sample system of powder provided by the utility model.
In figure, 1. powder pipes, 2. screwed samplers, 3. 2 sampling below atmospheric pressure pumps, 4. feed openings, 5. tremie pipes, 6. air inlets
Mouthful, 7. discharge ports, 8. material receiving ports.
Specific embodiment
It elaborates with reference to the accompanying drawings and examples to the utility model.
As shown in Figure 1, a kind of online secondary sample system of powder, 3 and are pumped including screwed sampler 2, secondary sampling below atmospheric pressure
Pipe-line system, screwed sampler 2 have feed opening 4, and closely connection tremie pipe 5, the cross-sectional direction of tremie pipe 5 seal feed opening 4
The secondary sampling below atmospheric pressure pump 3 is built-in with, secondary sampling below atmospheric pressure pump 3 is equipped with material receiving port 8, and the one side of secondary sampling below atmospheric pressure pump 3 is set
There are air inlet 6, opposite opposite side to be equipped with discharge port 7.
Secondary sampling below atmospheric pressure pump 3 and 5 tube wall contact site sealed set of tremie pipe, and material receiving port 8 is located at 5 cavity of tremie pipe
It is interior.
For the ease of receiving the material to fall, sampling process is more stablized, and the material receiving port 8 is located in 5 pipeline of tremie pipe
The center in footpath, 5 cavity top of face tremie pipe.
Shown in Fig. 1, the left side air inlet 6 of secondary sampling below atmospheric pressure pump 3 leads to compressed air, opposite opposite side equipped with discharge port
7, discharge port 7 can connect discharge nozzle.
For the ease of adjust sampling amount number, the size of the material receiving port 8 is adjustable, needs to adjust according to detection.
In addition to being used to be connected and be placed in powder pipe 1 with feed opening 4 except the upper and lower ends portion of tremie pipe 5, secondary negative pressure
Sampling pump 3 is built in the center section of tremie pipe 5, preferably molded-in in the middle and upper part of tremie pipe 5, ensures secondary sampling below atmospheric pressure pump 3
Vertical blanking pipeline section is sealingly disposed in, that is, the middle and upper part of tremie pipe 5 is vertically arranged, and is vertically arranged convenient for the samples fall down time-division
It dissipates, is not easy to accumulate；The part that tremie pipe 5 is located at 3 lower section of secondary sampling below atmospheric pressure pump is flexible, convenient for tremie pipe 5 away from feed opening 4
One end be placed in powder container, convenient for the remaining powder of recycling.
Shown in Fig. 1, the left side air inlet 6 of secondary sampling below atmospheric pressure pump 3 leads to compressed air, and a certain amount of powder sample is inhaled
In the material receiving port 8 for entering top, detection device is entered by the discharge port 7 of opposite side.Other samples drop back into powder pipe 1 by tremie pipe 5.
During sampling, screwed sampler 2 is inserted into powder pipe 1, the material receiving port 8 of secondary sampling below atmospheric pressure pump 3 upward, open by when sampling
Compressed air is opened, the sample that fraction falls into material receiving port is inhaled into secondary sampling below atmospheric pressure pump；The one end of tremie pipe away from feed opening
It is placed in powder container, most of sample does the movement of falling object and drops back into powder pipe from top to bottom.Such sampling mode is fast in real time
Fast direct, the sample of taking-up is very representative.Minimal amount of sample is only taken with regard to test request, most of powder can be met simultaneously
Body is also to revert in powder pipe.It will not cause to waste.
Primary sample uses screwed sampler, and sampling amount is big, representative good；Secondary sample is pumped using secondary sampling below atmospheric pressure,
Material receiving port caliber size is adjustable, by postsearch screening, chooses sub-fraction sample and enters test.
The Venturi effect pumped using the flow at high speed of compressed air and secondary sampling below atmospheric pressure forms a vacuum area, sample
Product suck secondary sampling below atmospheric pressure pump by vacuum area and then are sent into test sample equipment.
Since this device structure is simply compact, by the use of compressed air as powder conveying and scattered power, compared to tradition
Sampling mode can reach automatically continuously uniform sampling effect, reduce people's participation, while greatly improve sampling precision and effect
Rate realizes real time sample.
