Abstract
Train naphtha tank car unloading system, including the unloading oil filling riser with oil-immersed pump, the unloading oil filling riser include the standpipe connected with oil pipeline, and tube and the nanubrium with oil-immersed pump, technical points are：Also include sweeping warehouse receipt member, the warehouse receipt member of sweeping includes sweeping storekeeper, and the pneumatic diaphragm pump being connected with sweeping storekeeper, pneumatic diaphragm pump discharge connects with unloading oil filling riser standpipe；The storekeeper of sweeping is anti-static rubber tube, and aluminium head is fixed with below anti-static rubber tube, and some breach are provided with below aluminium head.The utility model structure efficiently solves oil-immersed pump, and to sweep storehouse train tank car residual base oil excessive, the problem of causing oil product to lose.
Description
Technical field
It the utility model is related to petroleum chemical industry train and unload and sweep storehouse systems technology field, specifically a kind of train
Naphtha tank car unloading system.
Background technology
Shenyang wax carburetion product subsidiary factory train loading-unloading vehicle trestle work is provided with naphtha unloading system, and the system uses and above unloads technique,
Unloading oil filling riser is equipped with Hydrodynamic oil-diving pump, and carries stripping function.The system exists during actually unloading and sweeps the not thorough feelings in storehouse
Condition, every is unloaded rear tank car and all leaves 100 kilograms or so base oils, and year is accumulative up to 180 tons, serious waste phenomenon be present.It is not thorough to sweep storehouse
Bottom main cause has：First, due to train tank car collection oil pit by through hole（It is commonly called as navel）Diameter is smaller, with oil-immersed pump pump head size difference not
More, oil-immersed pump can not be placed into collection oil pit by through hole center well；2nd, train tank car model is different, part tank car bottom collection oil pit by through hole with
Not on the same line, oil-immersed pump can not be placed into collection oil pit by through hole handling manhole；3rd, the less oil-immersed pump of tank car inner fluid can not be inhaled
When oily, oil-immersed pump is closed（Close motor）Oil filling riser vent valve is opened, trapped fuel is flowed back in tank car again in oil filling riser.
Utility model content
The purpose of this utility model is：A kind of train naphtha tank car unloading system is provided, unloaded not with solving train tank car
The problem of net, base oil is reclaimed as far as possible and reduces loss.
The utility model is achieved by the following technical solution：Train naphtha tank car unloading system, including band latent oil
The unloading oil filling riser of pump, the unloading oil filling riser include the standpipe connected with oil pipeline, tube and the nanubrium with oil-immersed pump, its skill
Art is characterized by：Also include sweeping warehouse receipt member, the warehouse receipt member of sweeping includes sweeping storekeeper, the pneumatic diaphragm pump being connected with sweeping storekeeper, gas
Dynamic membrane pump outlet connects with unloading oil filling riser standpipe；The storekeeper of sweeping is anti-static rubber tube, is fixed with below anti-static rubber tube
Aluminium head, some breach are provided with below aluminium head.
Further：The storekeeper aluminium head of sweeping is provided with hook, sweeps storekeeper body and is fixed by way of buckle or bondage
It is described to be articulated on the clip being located on the tube of unloading oil filling riser on the tube of unloading oil filling riser.
The beneficial effects of the utility model are：
This structure efficiently solves oil-immersed pump, and to sweep storehouse train tank car residual base oil excessive, the problem of causing oil product to lose.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 sweeps storekeeper structural representation to be of the present utility model.
Number explanation in figure：1 is naphtha tank car, and 2 be oil-immersed pump, and 3 be standpipe, and 4 be tube, and 5 be nanubrium, and 6 be to sweep storehouse
Pipe, 7 be pneumatic diaphragm pump, and 8 be anti-static rubber tube, and 9 be aluminium head, and 10 be breach, and 11 be hook, and 12 be clip.
Embodiment
It is as shown in Figure 1-2 the unloading system of the utility model train naphtha tank car 1, including corresponds to each section car body respectively
If stem structure identical part, each part includes the unloading oil filling riser with oil-immersed pump 2, and the unloading oil filling riser includes and petroleum pipeline
Standpipe 3, tube 4 and the nanubrium 5 with oil-immersed pump of road connection, in addition to warehouse receipt member is swept, the warehouse receipt member of sweeping includes sweeping storekeeper
6, the pneumatic diaphragm pump 7 being connected with sweeping storekeeper, pneumatic diaphragm pump discharge connects with unloading oil filling riser standpipe；The storekeeper of sweeping is anti-quiet
Electric sebific duct 8, aluminium first 9 is fixed with below anti-static rubber tube, some breach 10 are provided with below aluminium head.
Sweep storekeeper and use anti-static rubber tube, the structure that aluminium head is fixed with below anti-static rubber tube is effectively reduced electrostatic
Caused possibility, and safety is farthest ensure that, breach is provided with below aluminium head, can effectively ensure to sweep in storekeeper
Air pressure balance, sebific duct distribution deformation is prevented, improves and sweeps storehouse efficiency and reliability.
Preferably：The storekeeper aluminium head of sweeping is provided with hook 11, sweeps storekeeper body and is fixed by way of buckle or bondage
It is described to be articulated on the clip 12 being located on the tube of unloading oil filling riser on the tube of unloading oil filling riser.
Preferably：Storekeeper road is swept sweeping to be provided between storekeeper and pneumatic diaphragm pump, as shown in the long straight line in Fig. 1 middle and lower parts.
Storekeeper is swept with being equipped with valve on pneumatic diaphragm pump, for controlling different branch to open.
During unloading, when the base oil that remaining a small amount of oil-immersed pump can not be drawn, drawn using warehouse receipt member is swept,
Pump discharge valve is first opened, stripping pump outlet line is connected with standpipe so as to fill oil；Pneumatic diaphragm pump is opened to sweep with corresponding
Valve between storekeeper, then slowly open stripping pump power（Nitrogen）Ball valve, control pressure are not more than 0.4MPa.
This structure efficiently solves oil-immersed pump, and to sweep storehouse train tank car residual base oil excessive, the problem of causing oil product to lose.
