Description

The flow water automatic sampler

Technical field

The utility model relates to a kind of sampler, particularly relates to a kind of flow water automatic sampler.

Background technology

Material sampling generally is divided into artificial sample and sampling automatically in the production control process, and the former decide the regularly manual sampling of people, time-consumingly takes the people, and is very inconvenient, particularly takes a sample to be unfavorable for that the monitor staff's is healthy in than rugged surroundings.Chinese patent 87211031 discloses a kind of automatic water quality sampler, be the automatic water quality continuous sampling system of a kind of pendulum-type, it is adjusted post, mercury counterweight pipe, left and right sides tipping bucket, water quality by left and right sides capacity and introduces valve, edge of a knife support, oil cylinder resistance system, divides assembling system, sample receiving tube, the packing mouth of a river, left and right sides drip tray, linkage, dead man, frame, pulls out wheel and the packing drip tray is formed.This automatic sampler, complex structure uses limitation, can only take the low discharge homogenous mass, is mainly used in the water quality sampling, can not be used for the sampling of big flow heterogeneous body material such as slurry.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, and stable performance can be used for taking under the various environmental baselines granularity less than≤2mm, the flow water automatic sampler that the slurry material of concentration≤50% is taken a sample automatically accurately and reliably.

The utility model flow water automatic sampler comprises casing, is arranged on the balanced sampling mechanism in the casing, and is arranged on the constant pressure water tank on the casing.Wherein, balanced sampling mechanism is by feet, by the foot-mounted sampling support of rotation axis, be arranged on the mass of sampling support one end, be fixed on the sampling support other end and with sampling support rotation axis vertical stopple coupon, be fixed on the water container on the sampling support, and be positioned at casing and the sample loading bucket composition corresponding with stopple coupon.Stopple coupon can be convenient to select according to the sampling needs stopple coupon of different size by being bolted on the sampling support, and an end of stopple coupon stretches out outside the casing, has sampling groove on its this end, and sampling groove communicates with the stopple coupon other end.The fulcrum of this balanced sampling mechanism is a rotation axis, mass generally is made of polylith spare, be enclosed within on sampling support one end, and move left and right thereon, balance with the adjustment sampling mechanism, the polylith spare structure of mass is mainly used in the initial adjustment of balance, and the move left and right of its mass then is used for the fine tuning of balance.Use the stopple coupon of different size, or, all can pass through the mass adjustment in use owing to after reasons such as material deposition cause balanced sampling mechanism out of trim; Going to the bottom of casing has apopore, is convenient to the water outflow in the water container, and the side has door and stopple coupon moves the hole; Constant pressure water tank is positioned at above the casing, as the operation power source of balanced sampling mechanism, its

Be provided with water intaking valve and electronic outlet valve, electronic outlet valve is used to control the flow of water outlet, promptly controls the time that water container is filled with by clear water, has also just controlled sample time and sampling number of times.Electronic outlet valve is corresponding with water container by the inlet opening on the casing, and the clear water that promptly electronic outlet valve flows out flows directly in the water container.

The principle of work of the utility model flow water automatic sampler is, during use this machine is installed in and waits to get by the baffle-box of material, and material inlet and material outlet are arranged on the baffle-box, has certain height poor between the two.The movement locus of material in baffle-box is a para-curve, and this parabolic path and stopple coupon direction of motion intersect.When water container was anhydrous, the sampling support was under the mass effect, and system's center of gravity is positioned at mass on one side, and at this moment, the sampling support is in steady state (SS); When clear water flows into water container by electronic outlet valve (by controller control) and increases, the center of gravity of sampling mechanism is gradually to moving in the other direction, when the clear water in the water container reaches a certain amount of and is enough to overcome the rotary resistance that mass produces, the sampling support rotates, stopple coupon rotates thereupon, sampling groove is moved downward cut streams, and be positioned at below the streams, be unstable state this moment, along with water in the water container is emptied, system's center of gravity is got back to mass rapidly on one side, sampling support backward rotation, stopple coupon rotates thereupon, makes sampling groove cut streams once more, be returned to initial equilibrium state, the material sample that enters in the sampling groove flows in the sample loading bucket from the other end along stopple coupon.In like manner, system enters next working cycle.

The utility model flow water automatic sampler has the following advantages: 1) sampling automatically, accurately and reliably, and stable performance, sample time and sampling number of times can be regulated easily and flexibly, can get instantaneous sample, also can get the compound sample of arbitrary period.2) be used as power with water, avoided electric equipment to make moist, can effectively work than rugged environment is medium-term and long-term.3) owing to be provided with constant pressure water tank, make the water pressure invariableness of its outflow, sampling action can be accurately, normally carry out.4) balanced sampling mechanism is arranged in the casing, and the sample of guaranteeing to collect under various environmental baselines makes sample reflect actual conditions truly not by outside contamination, by the door on the sampling cabinet, the sample loading bucket of can taking easily.5) simple in structure, easy to maintenance, use cost is low.Be applicable to various granularity≤2mm such as chemical industry, metallurgy and mine, the slurry material of concentration≤50% is taken a sample automatically.
