Description
Technical field
The utility model relates to a kind of sample devices that is used for medium sampling in the petrochemical complex storage tank, and particularly a kind of jar is automatic sampler down.
Background technology
GB4756 oil and liquid petroleum product sampling method stipulate that upper, middle and lower portion sampled point should be in its jar: " at oil tank level top liquid storage height 5/6 place; or be lower than middle part, liquid level 200mm place at liquid storage height 1/2 place, bottom liquid storage height 1/6 place or distance jar end 250mm place." at present oil product class medium needs frequently sample to offer user and technologist in the petrochemical complex storage tank; traditional approach is sampled as the tank deck sampling of manually climbing to tens meters height; the very loaded down with trivial details hardships of sampling process, that sampling precision relies on artificial feel to locate is very inaccurate; and the security of sampling is very poor, and sampling efficiency is extremely low.
Summary of the invention
The utility model provides a kind of oil sample accuracy height of taking at the problems referred to above, and is simple, convenient, and the sample man need not go up the following automatic sampler of jar of jar.
Automatic sampler under described jar, comprise storage tank, it is characterized in that: it by in the storage tank from motion tracking liquid storage surface with the position sampling mechanism, a jar down-sampling mounting hole and a jar outer controlling of sampling case are formed, describedly comprise: bottom support bracket with the position sampling mechanism, floating plate, thief rod, on, in, the down-sampling pipe, lanyard, the lower end of described thief rod and bottom support bracket axle connect, its upper end is connected with lanyard, the upper end of lanyard be provided with the tether ring, the tether ring is connected with floating plate by angle steel bar, on described, in, the upper end of down-sampling pipe is communicated with pot liquid respectively, its lower end is communicated with a jar end of root valve by metal hose and jar down-sampling mounting hole respectively, and the other end of jar root valve is communicated with sample valve respectively.
The outer controlling of sampling case of jar comprises: tank shell, case be plain flange lid, jar root valve, sample valve, ebullator, scavenge pipe, pneumatic switch behind, the input end of described ebullator is communicated with the input end of sample valve respectively, its output terminal is by being communicated with in scavenge pipe and sampling mounting hole and the storage tank, case plain flange lid behind is tightly connected with a jar down-sampling mounting hole, and metal hose connects by outer wall and blind flange and is tightly connected.
The length of described thief rod is 1/2 of the interior maximum liquid storage position of storage tank height, and the length of down-sampling pipe equals the length of 1/3 thief rod, and the length of middle sampling pipe equals the length of thief rod.
The up-sampling pipe is made up of lengths of steel pipes and metal hose, its lengths of steel pipes be located on the thief rod and with its equal in length, its metal hose is fixedlyed connected with the lanyard clip, its length is the 2/3 long of lanyard, the upper end of lengths of steel pipes is communicated with metal hose lower end thread seal.
The vertical height of described thief rod is a maximum liquid storage height 1/2 in the storage tank, and the height of the top sampled point of upper, middle and lower sampling pipe is respectively at 5/6,1/2,1/6 place with the position sampling mechanism.
The outer controlling of sampling case of jar is located on jar outer storage tank bottom plate top 200-900mm place sampling mounting hole blind flange, and it is apart from ground 1000-1600mm.Described floating plate can also be pontoon or ball float or other shapes
The beneficial effects of the utility model are: precisely locate automatically with liquid level with the position sampling mechanism, the sampling interface concentration is a place, operates in the controlling of sampling control box that all concentrates under jar outer jar.So not only alleviate the sampling working strength of workers but also guaranteed safety, particularly under the awful weather condition, more can show its superiority, the automaticity height is saved the sampling time, increases work efficiency.User's operation, installation, maintenance are convenient in the integrated design of operation cabinet.The sample can internals are to the not enough 20Kgf of acting force of floating plate, and are lighter many than traditional sampling device, effectively stopped the consequence that the traditional sampling device can draw the floating plate that inclines, and the more similar height of sampling precision, specific as follows:
The perforate of traditional approach be three point sampling mounting holes add scavenge pipe hole four hole modes be reduced to one the sampling mounting hole, sampling operation is partly unified to be placed in the airtight casing, both made things convenient for the sample man to operate, security personnel also conveniently lock, high oil product increase can be set up the warm pipeline of companion in the controlling of sampling casing at viscosity in addition, makes things convenient for flowing of sampling media.
2. the sampling precision height is set because geometrical principle is pressed in the strictness of sampling pipe length, so sampling precision is very high.
3. the sampling follower is by the reinforcement of sampling sway brace, so avoided sampling pipe because gravity and the crooked phenomenon that sampling point position departed from, guarantee that further the up-sampling site error is no more than 1%, middle sampling pipe is no more than 3%, and the down-sampling pipe is no more than 5%.
4. sampling arm adopts the hollow closed structure, and the gravity of the inner part of guaranteeing to sample reduces by one times once with the buoyancy difference, and bending reduces sampling precision owing to gravity further to have reduced sampling pipe.Guarantee that simultaneously sampling is no more than 20kgf with position mechanism to floating plate or pontoon acting force, guarantee the security of sampling, further guarantee sampling precision;
5. a jar outside branch displacement is finished by driving pump is disposable, has guaranteed that sampling can not descend owing to remaining old sample makes sampling precision.
