Abstract
The utility model discloses an automatic cleaning device for an oil supply pipe of aromatic hydrocarbon oil, and the problem that long heating time of aromatic hydrocarbon oil pipelines of banburying workshops in the prior art is required to restore production after production halts is solved. An oil outlet of an aromatic hydrocarbon oil tank (1) is connected to one end of an oil outlet pipe (2), the other end of the oil outlet pipe (2) is connected to a first end of a tee (4) via an oil outlet check valve (3), a second end of the tee (4) is connected to one end of a first stop valve (6) via an oil inlet pipe (5), the other end of the first stop valve (6) is connected to one end of an oil return pipe (7), and the other end of the oil return pipe (7) is connected to an oil return opening of the aromatic hydrocarbon oil tank (1) via a second stop valve (8). A third end of the tee (4) is connected to a compressed air inlet pipe (12) via an electric control two-position cut-off valve (10), and the electric control two-position cut-off valve is electrically connected to an electric control cabinet (13). The automatic cleaning device for the oil supply pipe of aromatic hydrocarbon oil is especially applicable to the banburying workshops in rubber factories.
Description
Technical field
The utility model relates to a kind of pipeline cleaning device, and is particularly a kind of to producing the device that the employed aromatic naphtha pipeline of doughnut is cleared up.
Background technology
In tyre stock was produced, aromatic naphtha was indispensable important source material as softening agent.Aromatic naphtha viscosity when normal temperature is big especially, mobile extreme difference, therefore aromatic naphtha is when the banburying operation is used, at first in holding vessel, be heated to about 80 degree Celsius, after making it possess good mobility, be sent to the oil plant pipeline by oil pump again and be transported in the banburying oil scale, satisfy production requirement with the automatic weighing that guarantees oil plant.In order to prevent that the aromatic hydrocarbons oil plant from turning cold in transport pipeline, generally install electric heater and heat-insulation layer additional at the oil plant pipeline, and take to strengthen the pump oil pressure method of oil pump, but after the power failure termination of pumping, can retain a large amount of aromatic naphtha in the pipeline, when particularly long-time stopping production has a power failure, the residual aromatic hydrocarbons oil plant hardening that in transport pipeline, can turn cold in the pipeline, after sending electricity again, heating to the aromatic naphtha of the hardening that turns cold can need the long time, the loss that has simultaneously also strengthened oil pump has had influence on normally carrying out of producing.
Summary of the invention
The utility model provides a kind of aromatic naphtha oil supply pipe automatic cleaning device, the aromatic naphtha conveyance conduit that has solved existing banburying workshop after stopping production, resume production again need longer heat time heating time technical problem.
The utility model overcomes the above problems by following scheme:
A kind of aromatic naphtha oil supply pipe automatic cleaning device, comprise the aromatic hydrocarbons oil tank, oil-out on the aromatic hydrocarbons oil tank is communicated with an end of flowline, the other end of flowline is communicated with first port of threeway by fuel-displaced check valve, second port of threeway is communicated with an end of first stop valve by sending oil pipe, the other end of first stop valve is communicated with an end of oil return pipe, the other end of oil return pipe is communicated with oil return opening on the aromatic hydrocarbons oil tank by second stop valve, the first oily scale is communicated with sending oil pipe by the 4th stop valve, the 3rd port of threeway is communicated with the output of compressed air check valve, the input of compressed air check valve is communicated with an end of the 3rd stop valve by automatically controlled two stop valves, the other end of the 3rd stop valve is communicated with the compressed air input pipe, and automatically controlled two stop valves are electrically connected with electrical control cubicles.
The second oily scale is communicated with sending oil pipe by the 5th stop valve, and the 3rd oily scale is communicated with sending oil pipe by the 6th stop valve.
The utility model has thoroughly been eliminated aromatic naphtha oil supply pipe blockage problem, has reduced the loss of oil pump, has guaranteed normally carrying out of aromatic naphtha conveying production.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of aromatic naphtha oil supply pipe automatic cleaning device, comprise aromatic hydrocarbons oil tank 1, oil-out on the aromatic hydrocarbons oil tank 1 is communicated with an end of flowline 2, the other end of flowline 2 is communicated with first port of threeway 4 by fuel-displaced check valve 3, second port of threeway 4 is communicated with an end of first stop valve 6 by sending oil pipe 5, the other end of first stop valve 6 is communicated with an end of oil return pipe 7, the other end of oil return pipe 7 is communicated with oil return opening on the aromatic hydrocarbons oil tank 1 by second stop valve 8, the first oily scale 15 is communicated with sending oil pipe 5 by the 4th stop valve 14, the 3rd port of threeway 4 is communicated with the output of compressed air check valve 9, the input of compressed air check valve 9 is communicated with an end of the 3rd stop valve 11 by automatically controlled two stop valves 10, the other end of the 3rd stop valve 11 is communicated with compressed air input pipe 12, and automatically controlled two stop valves 10 are electrically connected with electrical control cubicles 13.
The second oily scale 17 is communicated with sending oil pipe 5 by the 5th stop valve 16, and the 3rd oily scale 19 is communicated with sending oil pipe 5 by the 6th stop valve 18.
When the aromatic naphtha oil supply pipe normally moved, fuel-displaced check valve 3 was opened, and compressed air check valve 9 is closed, and aromatic naphtha follows the normal fuel injection operation of endless tube road; After termination of pumping, fuel-displaced check valve 3 is closed, compressed air check valve 9 is opened, give automatically controlled two stop valves, 10 power supplies by electrical control cubicles 13, automatically controlled two stop valves 10 feed the 3rd stop valve 11 compressed air in the compressed air input pipe 12 are inserted in the aromatic naphtha oil supply pipe, medium wind begins to follow the cleaning of endless tube road and retains aromatic naphtha, realize automatic cleaning function, the opening time of automatically controlled two stop valves 10 is controlled by the time relay, its setting value arranges according to pipeline length, thickness, generally controls at 5 minutes-10 minutes.
