Description
Technical field
The present invention relates to detection field, particularly, the present invention relates to a kind of detection interface/device for fixed point sampling and method, more specifically, the present invention relates to a kind of wide-mouth type two end open and close type stratified liquid sampler and methods.
Background technology
At Chemical Manufacture or sewage treatment area, often occur that various materials concentrates on the situation of same storage tank.Now, as do not possessed compatibility between different material, there will be unavoidably because of the different laminations that cause of density.
On the other hand, common storage tank liquid level gauge only can display channel in the total height of material, can't layering show each material interface.But, from the Material control angle, the physical location of accurately grasping different material interface in groove is but very necessary.Hereinafter with the profit occurred in production run, being layered as example describes.
For example, technique waste water or oily waste water are deposited mainly with storage tank, and intermittence is sent to special wastewater treatment equipment.For oily waste water or factory effluent, for preventing wherein oil content, discharge, often be equipped with to be specifically designed to and collect waste water, and concentrate the waste water collection tank that is disposed to treating apparatus.But in wastewater trough, the profit layering interfaces often is difficult for defining, at waste water, containing in the Chuck Steak situation, with liquid level gauge, be only None-identified profit layering position.This just the work make troubles (signal See Figure) such as sends outside to waste water.Usually, actual mechanical process at this moment can only carry out the scene monitoring by the staff, can draining after heavy oil is sent.Seeing oil bloom again toward light oil groove feeding thereafter.For this reason, owing to not knowing wherein level condition, on-the-spot monitoring personnel must garrison for a long time, have increased staff's workload.
For this reason, need a kind of like this sampler, described sampler can be got the single liquid point sample, also can the reference tube height, and successively test and directly take out layering interfaces, reduce the number of times groped under the situation of unknown interface, reduces the running time.
For addressing the above problem, the invention provides a kind of wide-mouth type two end open and close type stratified liquid samplers, described wide-mouth type two end open and close type stratified liquid samplers adopt two ends semi-open-type wide-mouth design, make to sample cylindrical shell and be full of the sampling cylindrical shell with prestissimo in settling process, and sampling cylindrical shell sinking process reaches and minimizes liquid layered generation of interfaces disturbance in groove.Thus, can improve sampling precision.
In addition, the present invention is by sampling cylindrical shell cylindrical shell sight glass (band scale) is set, but after the sampling cylindrical shell is pulled out storage tank, the very first time is determined the liquid layered situation, does not need liquid rotating to redefine interface later, and related layering interfaces depth determination method is simple.
