Abstract
The utility model relates to an off-standard sample-retaining sampler which comprises a casing, a low temperature storing case and a sampling bottle. The sampling bottle is placed in the low temperature storing case. The exceeding standard sample-retaining sampler also comprises a stored sample overflow device, a sampling pump and a PLC controller, which collect samples synchronously with the analyzing of water samples. The stored sample overflow device is communicated with the sampling bottle by a pipeline which is provided with the sampling pump. An inlet of the sampling bottle is provided with a controlled valve. The pipeline is connected with a drain pipe which is provided with a drain valve. A start switch of the sampling pump, the controlled valve and the drain valve are connected with the PLC controller. The PLC controller comprises the start switch which is used for receiving an analysis result and starting the sampling pump, if an off-standard signal is received, the start switch starts the controlled valve at the same time; if a normal signal is received, the start switch starts an off-standard sample-retaining control module of the drain valve at the same time. The utility model provides an off-standard sample-retaining sampler which is linked with an analyzing instrument or a monitoring system and which starts retaining the sample with high efficiency when the analysis result exceeds the standard.
Description
Technical field
The utility model relates to a kind of water body sampling apparatus, especially a kind ofly is used for the sampling apparatus that the monitoring water quality on line system keeps sample to overstandard waste water.
Background technology
China is a country that water resource relatively lacks; in recent years; along with the quickening of process of industrialization and improving constantly of the level of urbanization, water pollution is serious day by day, and how protecting water resource and sewage is carried out exhausting control has become one of important state basic policy of national sustainable development.Water quality online auto monitoring technology can be carried out real-time and continuous monitoring to the pollution source discharging, is a kind of rapidly environmental monitoring technology of development in recent years, has great importance for improving total amount of pollutant control and environmental management ability.Because the complicacy and the uncertainty of waste water quality, the monitoring water quality on line system generally need sample automatically to overstandard waste water at present, and does to keep sample analysis, for follow-up law enforcement for environmental protection provides foundation.
The equal proportion sampling device is adopted in the automatic sampling of monitoring water quality on line at present usually, though can finish the sampling of various ways, as timing sampling, flow proportional sampling, external trigger sampling, manual sampling etc., but be difficult to realize synchronized sampling with analytical instrument and monitoring system, usually start after discovery waste water exceeds standard, there are hysteresis quality in water sample and the analysis water-like gathered.If will guarantee the simultaneity of water sample, just must in analysis-e/or determining, keep sample, no matter whether waste water exceeds standard and all keep sample like this, will cause the waste of human and material resources and financial resources.
Summary of the invention
No matter all keep sample, keep sample efficient low deficiency in order to overcome existing when realizing synchronized sampling, whether the exceeding standard of sampling thief that keep sample of exceeding standard, the utility model provide a kind of with analytical instrument or supervisory system interlock, when analysis result exceeds standard, start the efficient high sampling thief that keeps sample that exceeds standard that keeps sample, keeps sample.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of sampling thief that keeps sample that exceeds standard, comprise housing, cryopreservation case and sampling bottle, described sampling bottle is positioned at the cryopreservation case, the described sampling thief that keeps sample of exceeding standard also comprises storage sample overflow device, sampling pump and PLC controller with the analysis water-like synchronous acquisition, described storage sample overflow device is communicated with sampling bottle by pipeline, is provided with sampling pump on described pipeline, is provided with Controlled valve in the porch of described sampling bottle, connect evacuated tube at described pipeline, described evacuated tube is provided with exhaust-valve; The starting switch of described sampling pump, Controlled valve and exhaust-valve are connected with the PLC controller, described PLC controller comprise be used to receive analysis result after, start the starting switch of sampling pump, as being the signal that exceeds standard, open Controlled valve simultaneously, as be normal signal, open the control module that keeps sample that exceeds standard of exhaust-valve simultaneously.
Further, described sampling bottle has and is no less than three, and the porch of described each sampling bottle is provided with corresponding Controlled valve.
Further again, described Controlled valve and exhaust-valve are miniature electromagnetic valve.
Further, described housing top is electric control box, described lower housing portion is the cryopreservation case, described cryopreservation upper box part is for dividing the bottle guide tank, the middle part of described cryopreservation case is that sampling bottle is placed drawer, described sampling bottle is positioned at described sampling bottle and places drawer, and the bottom of described cryopreservation case is an accessory case.
The described sampling thief that keeps sample of exceeding standard also comprises and is used to the alarm of pointing out the user to change or cleaning sampling bottle, described PLC controller also comprises and is used for recording corresponding sampling bottle and being full state at the postscript that keeps sample of exceeding standard, when all sampling bottles send the alarm module of alarm command when all being full to alarm device, described alarm module connects alarm.
The beneficial effects of the utility model mainly show: 1, sampling thief can link with analyser or monitoring system, starts sampling when analysis result exceeds standard, and has only overstandard waste water just can be kept sample, and efficient height keeps sample; 2, adopt miniature electromagnetic valve to divide a bottle technology, be different from the stepper motor rotation and divide a bottle technology, mechanism without spin, reliability is higher; 3, sampling bottle needn't circle distribution, but arranged has been dwindled the reefer volume, makes full use of the space, and it is convenient to change sampling bottle, and is nearlyer 1/3 than domestic other forms of automatic sampler volume-diminished, weight saving nearly 1/4; 4, adopt PLC control, reliable, simple and direct-viewing operation.Have prompt functions, be user-friendly to; 5, keep sample that quantity is many, capacity is big, the sample retention stable temperature control is accurate simultaneously, has improved the authenticity of the waste water that keeps sample.
