Abstract
The utility model discloses a tank farm oil automatic sampling device which comprises a valve and a sampling pipeline and is characterized in that a sampling point is arranged on the outer wall of a storage tank, a tank type aggregator is arranged at the bottom of the storage tank, the sampling pipeline is connected between the sampling point and the aggregator, the valve is arranged at the lower end of the sampling pipeline, the aggregator is also provided with an analysis pipeline, an oil return pipeline, a nitrogen gas pipeline and a corresponding valve, and the oil return pipeline is connected to an oil return hole which is arranged at the bottom of the storage tank. Compared with the prior art, the utility model has the advantages of little corrosion, difficult fracture and blockage of a sampling pipe, simple installation, convenient maintenance and low cost, and avoids extracting stock liquid by a hand pump.
Description
Technical field
The utility model relates to oil sampling technical field in the petrochemical industry, specifically a kind of tank field oil product automatic sampling device.
Background technology
At present, the relevant oil sampling of petrochemical industry all adopts manual sampling operation, be unfavorable for the accuracy and the security of sampling, and labour intensity is big.Along with the reach of science, continue to use manual tank deck sampling for many years, will be by sampling replacement automatically.
Following self-actuated sampler: A, self-regulated locate mode tank field oil product self-actuated sampler are arranged in the prior art.The pipeline of its sampling is built in the expansion bracket, expansion bracket top is provided with ball float, the bottom is provided with positioning disk, expansion bracket is positioned in the oil tank, device can be adjusted at random when liquid level changes in the oil tank, a plurality of sampling lines of diverse location can be set like this, sampling line can be restrainted together and draw from tank skin opening flange from the bottom of oil tank, be connected with the multidigit reversal valve, the multidigit reversal valve is connected with wobble pump, shake wobble pump the liquid storage in the stopple coupon is transported in the oil tank, so just can get the fresh oil sample of the relevant position of oil tank.B, standpipe multipoint mode tank field oil product self-actuated sampler.Its stopple coupon internal diameter is that the many stopple coupons of 6mm are formed, restraint in the stay pipe that inserts a upright DN40-DN80 together, be installed in the oil tank the inside, stopple coupon stretches out sample tap at the diverse location of stay pipe as requested, sampling line is drawn from tank skin opening flange from the bottom of oil tank, is connected with the multidigit reversal valve, and the multidigit reversal valve is connected with wobble pump, shake wobble pump the liquid storage in the stopple coupon is transported in the oil tank, so just can get the fresh oil sample of the relevant position of oil tank.
Above-mentioned prior art has alleviated worker's part labour intensity in the relevant oil sampling work of petrochemical industry, for contribution has been made in the production of industry.But it exists following defective or deficiency: stopple coupon is too thin and fracture easily and stop up along with pasta carries out telescopic folding among (1) above-mentioned A; (2) stopple coupon too carefully stops up among the above-mentioned B; (3) use wobble pump to extract the complicated damage easily of liquid storage equipment; (4) complexity is installed, is not easy to safeguard; (5) cost height.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, provide a kind of corrosivity little, install simple, easy to maintenance, and the low tank field oil product automatic sampling device of cost.
Its technical scheme is: the utility model comprises valve and sampling line.The storage tank outer wall is provided with sampling spot, tank bottom is provided with a jar shape aggregator, be connected with sampling line between sampling spot and the aggregator, the lower end of sampling line is provided with valve, also be provided with on the described aggregator and analyze pipeline, oil return pipeline, nitrogen pipeline and corresponding valve, the oil return pipeline is connected on the oil return opening of tank bottom.
Described sampling spot and sampling line are to each two at least of tank top settings by aggregator.Described sampling spot is to be connected with storage tank outer wall flange.
The utility model has compared with prior art: corrosivity is little, stopple coupon not frangibility, stop up, avoid using wobble pump extract liquid storage, install simple, easy to maintenance, and the low advantage of cost.
Description of drawings
Accompanying drawing is the one-piece construction synoptic diagram of a kind of embodiment of the utility model;
Embodiment:
With reference to attached Fig. 1 and 2, the utility model comprises valve 9 and sampling line 5.Storage tank 1 outer wall is provided with sampling spot 4, storage tank 1 bottom is provided with a jar shape aggregator 3, be connected with sampling line 5 along winding staircase 2 between sampling spot 4 and the aggregator 3, the lower end of sampling line 5 is provided with valve 9, also be provided with on the aggregator 3 and analyze pipeline 7, oil return pipeline 10, nitrogen pipeline 8 and corresponding valve, oil return pipeline 10 is connected on the oil return opening 6 of storage tank 1 bottom.Sampling spot 4 and sampling line 5 are according to each two at least of the height of producing sampling requirement and quantity settings.Sampling spot 4 is for being that flange is connected with storage tank 1 outer wall.
Concrete using method is to get bottom sample example: the sampling original state all becomes closed condition for all sampling line 4 valves, nitrogen valve, oil return valve and analysis pipeline 7 valves.When needing sampling, at first open bottom sampling line valve, open the nitrogen pipeline valve again and the liquid storage in the sampling line is pressed onto in the storage tank 1 (5 times in second are just enough), close the nitrogen pipeline valve open then and analyze the pipeline valve sampling with nitrogen.
