Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, the structural representation of the automatic safety sampling device provided for the utility model embodiment.
This automatic safety sampling device comprises: power part, comprises the pump that keeps sample, for providing the driving force of this device work; Keep sample parts, is connected with the first working hole of power part, comprises at least one bottle that keeps sample, and controls the solenoid valve of sample turnover in the corresponding bottle that keeps sample, and the sample introduction nesting tube be connected with solenoid valve; Stock layout parts, are connected with the second working hole of power part, for discharging waste liquid; Cleaning part, is connected with the second working hole of power part, for clean keep sample bottle and sample introduction nesting tube.Wherein, the number of the bottle that keeps sample in the present embodiment is three, but not as limit.
Further, the stock layout valve 7 that stock layout module comprises nesting port 3 and is applied to it, for discharging waste liquid.The distillation water valve 6 that cleaning module comprises the distillation mouth of a river 2 and is applied to it, leads to distilled water during for cleaning and keeping sample bottle 12,13,14; And air scoop 4, the air valve 8 be applied to it, when keeping sample bottle 12,13,14 for cleaning, blowing air stirs distilled water.Wherein, solenoid valve 9,10,11, stock layout valve 7, distillation water valve 6 and air valve 8 are normally close valve, could open after energising.Wherein, more thorough in order to what clean if desired, available watery hydrochloric acid or dust technology replace distilled water to clean.
Further, the pump that keeps sample is the liquor pump of the miniature peristaltic pump 5 of direct current supply, the liquor pump of rotating or two positive and negative installations.Realized the rotating of peristaltic pump 5 by the both positive and negative polarity of switch motor, and then reach the effect of sample introduction and stock layout, simultaneously can also control the sample size of sample introduction and stock layout by the working time of peristaltic pump 5.Wherein, the control circuit of the automatic safety sampling device that the utility model provides is simple, only needs to control the switch of above-mentioned valve and the rotating of peristaltic pump 5, can be single chip circuit or Programmable logical controller circuit.Therefore, compared to conventional apparatus, driving locating device and motor are required that very high drawback gives effective solution, and be not easy because machinery or circuit block fault cause the failure that keeps sample.
Further, bottle 12,13,14 upper end that keeps sample is provided with air hole, and lower end is connected with sample introduction nesting tube 15 and lower end bottleneck is provided with certain tapering.Design like this can avoid tradition to keep sample bottleneck bore greatly, the defect apt to deteriorate that sample and air contact surfaces amass, and stock layout is more clean.But it should be noted that in sample introduction nesting tube 15 bottle 12 of keeping sample, 13,14 public pipelines to try one's best short, to avoid causing cross pollution.
Further, for increasing the time of Sample storage, also after sample has kept sample, automatically adding the fixing agent meeting concerned countries standard-required in environmental monitoring industry, can also the bottle 12,13,14 that keep sample be arranged in cryostat, in order to long-time preservation.
Further, the automatic safety sampling device that the utility model embodiment provides can be set to each test as requested and all keep sample, or occurs that the abnormal data check means such as over-standard sample retention that keep sample are checked keeping sample.
It should be noted that, "left", "right" used herein, " on ", the noun of locality such as D score is for benchmark defines with the component relative position shown in scheming, obviously, the application of the above-mentioned noun of locality is only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In sum, the automatic safety sampling device structure that the utility model provides is simple, and not needing, with driving locating device and motor, does not need complicated control circuit yet, greatly reduce the failure rate of equipment; The bore of bottle of keeping sample is relatively little, is more conducive to guaranteeing the quality of water sample; Further, can detergent line and the bottle that keeps sample automatically before keeping sample at every turn, holding device clean, can not be polluted by last residual sample.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
