Abstract
The utility model relates to a sewage sampling device. The sewage sampling device comprises a sampling pipe for sampling sewage and a filter device; the filter device is of a mesh shield defined by a stainless steel mesh; one end of the sampling pipe is positioned in a water sample cavity of the filter device; the sampling pipe is provided with a self-suction water suction pump for sucking sewage in the water sample cavity into the sampling pipe; the water inlet of the self-suction water suction pump is communicated with the water sample cavity of the filter device by the sampling pipe. The sewage sampling device is simple in structure and convenient to use, impurities of sewage are filtered out by the filter device arranged in a sewage disposal pool, so the blockage condition when the self-suction water suction pump is used for sampling sewage is prevented or reduced as mush as possible.
Description
Technical field
The utility model relates to a kind of sewage sampling device.
Background technology
In the prior art, online COD monitor and online all automatic operations in unattended situation of nh 3-n analyser, be widely used in water quality environment monitoring system at present.As sewage treatment plant, emphasis monitoring pollutant discharge of enterprise mouth etc. have all been installed a large amount of online water quality monitoring instruments.Draw a small amount of sewage to these appliance requires timing automatic and analyze survey
Amount, but because the fluid transport pipeline of analytical instrument is thinner, in the time drawing sewage, need to install filtration unit additional, prevent the impurity occlusion analysis instrument pipeline in sewage.Existing water inlet sampler filtering system conventionally adopts submersible sewage pump to draw water and increases rear-mounted filtration unit thereafter, taken out sewage is filtered, but this mode is stopped up frequency high (almost every sampling will be stopped up for 2 times).
Utility model content
The problems referred to above that exist for prior art, the purpose of this utility model is to provide a kind of simple in structure, use and easy to clean and can prevent as far as possible or reduce the sewage sampling device of the problem that sampling stops up.
Solve this technical problem, the utility model adopts following technical scheme: a kind of sewage sampling device, comprise stopple coupon and filtration unit for sewage is sampled, described filtration unit is the guard with water sample chamber being surrounded by stainless (steel) wire, one end of described stopple coupon is positioned at the water sample chamber of filtration unit, on stopple coupon, be provided with the sewage in water sample chamber is extracted into the Self-pumping type water pump in stopple coupon, the water inlet of described Self-pumping type water pump is communicated with the water sample chamber of filtration unit by stopple coupon
Further, on the stopple coupon between Self-pumping type water pump and filtration unit, be provided with back purge system, the water delivering orifice of described back purge system is communicated with stopple coupon by washpipe, and the water inlet of back purge system connects water source.
Further, the impeller of described Self-pumping type water pump adopts stainless steel material to make.
Further, the bottom of described filtration unit is provided with the spring bottom valve that bottom, water sample chamber is opened.The caliber of described stopple coupon is 20mm.
With respect to prior art, the utlity model has following advantage: the sewage sampling device that the utility model provides, simple in structure, easy to use, first the impurity in sewage is filtered by the filtration unit being arranged in treatment tank, thereby prevent from as much as possible or reduced situation about stopping up occurs when Self-pumping type water pump is taken out sewage and adopted.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of sewage sampling device in embodiment.
Fig. 2 is the use constitutional diagram of sewage sampling device in embodiment.
In figure, treatment tank 1, stopple coupon 2, filtration unit 3, Self-pumping type water pump 4, washpipe 5, back purge system 6.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
embodiment:in the time that actual implementation is executed, referring to Fig. 1 and Fig. 2, a kind of sewage sampling device, comprise stopple coupon 2 and filtration unit 3 for the sewage for the treatment of tank 1 is sampled, the caliber of stopple coupon 2 is 20mm, and more foreign material are adhered in the excessive filtration unit outside of easily causing of caliber of stopple coupon, the caliber of stopple coupon is less, and to enter the hydraulic pressure of water quality monitoring instrument inadequate, impact detects, and when the caliber of sample pipe 2 is got 20mm, resultant effect is better.Filtration unit 3 is fixed on by expansion bolt on the sidewall for the treatment of tank 1, filtration unit 3 is the guards with water sample chamber that surrounded by stainless (steel) wire, one end of stopple coupon is positioned at the water sample chamber of filtration unit 3, on stopple coupon 2, be provided with the sewage in water sample chamber is extracted into the Self-pumping type water pump 4 in stopple coupon, the water inlet of Self-pumping type water pump 4 is communicated with the water sample chamber of filtration unit 3 by stopple coupon 2.Filtration unit 3 by the contaminant filter in sewage in treatment tank outside water sample chamber, therefore in Self-pumping type water pump 4 extract for detection of sewage do not contain larger impurity, thereby prevent that as much as possible stopple coupon 2 from stopping up, also prevented as much as possible that the fluid transport pipeline of online COD monitor and online nh 3-n analyser from stopping up simultaneously.
On the stopple coupon between Self-pumping type water pump and filtration unit, be provided with back purge system 6, back purge system 6 is for rinsing the stopple coupon between Self-pumping type water pump and filtration unit, the water delivering orifice of back purge system 6 is communicated with the stopple coupon between Self-pumping type water pump and filtration unit by washpipe 5, the water inlet of back purge system connects water source, generally uses low pressure water source.The tiny precipitation of piling up in stopple coupon is cleared up in arranging of back purge system, the fluid transport pipeline that has further prevented online COD monitor and online nh 3-n analyser stop up and online COD monitor and online nh 3-n analyser sampling cup in solids of sedimentation, improved the accuracy that detects numerical value.
In order to improve the corrosion resistivity of Self-pumping type water pump impeller, improve the tenure of use of Self-pumping type water pump, the impeller of Self-pumping type water pump preferably adopts stainless steel material to make.Clean out fast for the ease of the fine impurities that the impurity that is arranged in water sample chamber flushing out in the stopple coupon between Self-pumping type water pump and filtration unit and treatment tank 1 sewage is entered to water sample chamber, the spring bottom valve that bottom, water sample chamber is opened can be set in the bottom of filtration unit 3.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
