Technical field

The utility model relates to sampling technique field, in particular to a kind of multi-period automatic sampling apparatus of particulate matter.

Background technique

At the scene in production process, need to be sampled inspection by product of the standard to production, and determine whether qualification.Than Such as: food, feed, fertilizer particulate species produce product, and general manufacturing enterprise is still using the method manually sampled at present Sampling analysis work is carried out, manual sampling methods are easy to be influenced by the factors such as sampling time, equipment, artificial, lead to representativeness not By force, analysis result cannot reflect single batch product quality phenomenon, bring loss to production and follow-up service.

In the prior art, the method for acquiring sample mainly has two:

First is to take artificial sample method, and when artificial sample, labor intensive, sample is influenced by artificial, time factor It is bigger, it is not representative；

Second is to open equidistant aperture in the production line to carry out sample collection or drained with sampling pipe, then sampled； But the bad control of this method acquires sample size, and often extra sample is put back on production line, increases sample man's work Amount；There is no an automatic clearing function, the small product that powder is more or moisture is higher easily block or pickup pipe, or even agglomerates and fall into adopting Sample bucket, impact analysis result.

Specific embodiment

The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical It is novel, it is not intended to limit the scope of the utility model.

As shown in Figure 1, a kind of multi-period automatic sampling apparatus of particulate matter, including bracket 1 and sampling pipe 2, the sampling pipe 2 Inclination is placed in the upper end of the bracket 1；The middle part upper end of the sampling pipe 2 is provided with thief hatch 3；The middle part of the sampling pipe 2 It is set with casing 4；

The upper end of 2 lower part of sampling pipe is connected with cylinder 5, and the telescopic end of the cylinder 5 is connect with described sleeve pipe 4；Institute When stating the telescopic end stretching of cylinder 5, described sleeve pipe 4 is driven to close the thief hatch 3, when the telescopic end of the cylinder 5 is shunk, band Dynamic described sleeve pipe 4 opens the thief hatch 3；

The lower part of the sampling pipe 2 is connected with sample convergence pipe 6, and the lower section of the sample convergence pipe 6 is provided with sample bucket 7, the discharge port of the sample convergence pipe 6 extends in the sample bucket 7.

It further include PLC control cabinet 8 in above-described embodiment, wherein PLC controller 13 is SIEMENS PLC control cabinet S7-300； The PLC control cabinet 8 is connect with the cylinder 5 by tracheae, and the telescopic end that the PLC control cabinet 8 controls the cylinder 5 carries out It is flexible.

In above-described embodiment, the telescopic end of the cylinder 5 is connect by extension bar 9 with described sleeve pipe 4.

In above-described embodiment, the upper end of 2 lower part of sampling pipe is provided with Butterworth Hatch 10, and the Butterworth Hatch 10 passes through tracheae It is connected to cleaning device.

In above-described embodiment, the top of the sampling pipe 2 is connected with sundries convergence pipe 11, and the sundries converges under pipe 11 Side is provided with debris barrel 12, and the discharge port of the sundries convergence pipe 11 extends in the debris barrel 12.

In above-described embodiment, the sampling pipe 2 and casing 4 are made of stainless steel.

Implement the technical program, when starting PLC control cabinet 8, is delayed after the regular hour, begins to send out controlling of sampling and refer to It enables, cylinder 5 is controlled by the DC24V power of electromagnetic valve in control PLC control cabinet 8 and is closed, cylinder 5, which is closed, directly drives casing 4 It shrinks, casing 4 opens the thief hatch 3, and the particulate matter sampled enters sampling pipe 2, the particulate matter sampled by thief hatch 3 It is rolled in sampling pipe 2 to the lower part of sampling pipe 2, is finally flowed into sample bucket 7 after sample convergence pipe 6 collects, realization Grain object sample collection；

After certain sampling time, the DC24V power of electromagnetic valve control cylinder 5 in PLC control cabinet 8 starts, cylinder 5 Telescopic end stretch out, the telescopic end of cylinder 5 drives casing 4 mobile, and described sleeve pipe 4 closes the thief hatch 3, then completes primary Sampling；Pause after a certain period of time, is closed again through the DC24V power of electromagnetic valve control cylinder 5 in control PLC control cabinet 8, is beaten Thief hatch 3 is opened, continues second and samples, work repeatedly, until reaching the sampling number of setting；

After entire sampling is completed, starts cleaning device, entered in sampling pipe 2 by 10 blowback air of Butterworth Hatch, it will Inside upper part of the remaining sample sundries from the lower inside blowback of sampling pipe 2 to sampling pipe 2 in sampling pipe 2, it is residual in sampling pipe 2 Sampling pipe clogging when the sample sundries stayed is through in sundries convergence pipe 11 to debris barrel 12, preventing the sampling of sampling pipe 2.

Technical scheme is realized and automatically controls sampling, and manual labor is avoided, and reduces labour, also avoids simultaneously Because sample representativeness is representative poor caused by artificial consciousness, single batch product quality phenomenon cannot really be reflected by analyzing result, The problems such as bringing loss to production and follow-up service；Also according to analysis sample size requirement, parameter setting is carried out, reaches sample and adopts The adjustable purpose of amount processed, the amount of avoiding the occurrence of multiprocessing or few the case where not enough the analyzing appearance of amount；It can also clean in time, prevent from adopting Sampling device blocking, while reducing food safety and sanitation hidden danger.

Compared with the prior art, the utility model by timing, determine frequency progress machine sample automatically, avoid human factor Influence sample result, keep sample more representative, simultaneously because timing, determine frequency sampling, the total amount of sample is guaranteed, keeps away Exempt from sample excessively to waste, sampling randomness is strong, reduces random error；Furthermore it is practical, it is applied widely, it can be used for big On the dry particle sampling of majority, such as: the granulated sugar of particulate matter, fertilizer, feed, rice, beans；Structure, control principle It is all very simple, it is easy production, it is at low cost, while being able to satisfy automation and intelligentized demand；Fully-mechanized sampling, sample generation Table is strong, while can reduce labor intensity, solves the problems, such as that labour is in short supply；Food hygiene and safety hidden danger can be further decreased；Energy Enough automatic cleanings, prevent from blocking, and guarantee that sampling is normally carried out every time.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
