Abstract
The utility model relates to an online washing unit that is used for differential level gauge connecting pipe of extraction tower, its characterized in that: it includes washes the displacement pump, the output that washes the displacement pump is connected with two flushing line, each the last control valve that all is provided with of flushing line, two flushing line's end is connected respectively on two connecting pipes, wash the input of displacement pump and connect a solvent jar. It is vice solvent pump to wash the displacement pump. The utility model discloses can be applied to washing on line of the differential level gauge connecting pipe of extraction tower widely.
Description
Technical field
The utility model relates to a kind of on-line rinsing device for extraction tower differential pressure type liquid level meter connecting pipe, belongs to technical field of measuring equipment.
Background technology
Differential pressure type liquid level meter is widely used in the industrial processes such as oil, chemical industry, metallurgy, electric power, food, papermaking, medicine, weaving, for tracer liquid differential pressure, gauge pressure and absolute pressure, and the liquid level of liquid in opening or closed container.
Patent CN201666807U discloses a kind of device preventing pressure pipe of transmitter meter from being blocked, and this device realizes connecting pipe blocking cleaning by blowback air, but inapplicable for the liquid level gauge measuring liquid-liquid circle position.
In prior art, in solvent deasphalting pilot-plant, the bottom of extraction tower 1 is provided with two connecting pipes 2, and differential pressure type liquid level meter 3 is arranged between two connecting pipes 2 (as shown in Figure 1).When adopting extraction tower circle position in differential pressure type liquid level measurement amount solvent deasphalting pilot-plant, because asphalt viscosity is large, adsorptivity is stronger, in use may cause the asphaltene deposition of connecting pipe and extraction tower junction, absorption and blocking, directly affect the measurement result of differential pressure type liquid level meter.Even need to pull down connecting pipe to clean, therefore can affect the normal use of differential pressure type liquid level meter.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide the wide strong and on-line rinsing device for extraction tower differential pressure type liquid level meter connecting pipe of good reliability of a kind of versatility.
For achieving the above object, the utility model takes following technical scheme: a kind of on-line rinsing device for extraction tower differential pressure type liquid level meter connecting pipe, it is characterized in that: it comprises a flushing displacement pump, described flushing volume delivery side of pump is connected with two clean-up lines, clean-up line described in each is provided with a control valve, the end of clean-up line described in two is connected on two connecting pipes; The input of described flushing displacement pump connects a solvent tank.
Described flushing displacement pump is secondary solvent pump.
The utility model is owing to taking above technical scheme, it has the following advantages: 1, the utility model is provided with a flushing displacement pump, the input of rinse solvent pump connects a solvent tank, rinse solvent delivery side of pump is provided with two clean-up lines, the end of two clean-up lines is connected on two connecting pipes, and the utility model structure is simple, easy to use.2, each clean-up line of the present utility model is provided with a control valve, in use, can rinses two connecting pipes according to the service condition of differential pressure type liquid level meter at any time, the junction of two connecting pipes and extraction tower can be avoided easily to block, good reliability.
Accompanying drawing explanation
Fig. 1 is the structural representation that prior art extraction tower connects two connecting pipes
Fig. 2 is structural representation of the present utility model
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 2, the utility model proposes a kind of on-line rinsing device for extraction tower differential pressure type liquid level meter connecting pipe, it comprises a flushing displacement pump 4, and the output rinsing displacement pump 4 is connected with two clean-up lines 5, each clean-up line 5 is provided with a control valve 6.The end of two clean-up lines 5 is connected on two connecting pipes 2.The input rinsing displacement pump 1 connects a solvent tank 7.
In above-described embodiment, rinsing displacement pump 4 can be secondary solvent pump.
The utility model in use, open rinse solvent pump 4, open control valve on each clean-up line 56 successively (when opening the control valve 6 on a wherein clean-up line 5, control valve 6 on another clean-up line 5 keeps closing), in solvent tank 7, liquid flows in each clean-up line 5 successively, rinses respectively to two connecting pipes 2.
The various embodiments described above are only for illustration of the utility model; wherein the structure, connected mode etc. of each parts all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
