Abstract
The utility model relates to a light oil loading/unloading oil filling riser for a tank car, which comprises a suction tube, a straight tube connected with the suction tube and a swinging tube connected with an outlet conduit, wherein, a movable joint is arranged between the straight tube and the swinging tube, the utility model is provided with a locking mechanism to cause the swinging tube to swing and suck oil, a tubular jetting pressurizer is arranged in the suction tube and the straight tube and is connected with a return tube which is connected with the position of a material outlet or a power pump, and an injection nozzle towards the direction of physical distribution is arranged at the end of the jetting pressurizer on the return tube. The utility model provides an economical, high-efficiency and safety oil filling riser for unloading and is particularly suitable for unloading an oil tank car and a tank car loaded with light-weight fuel products or volatile chemicals.
Description
The utility model relates to a kind of improvement of tank car light oil loading and unloading oil filling riser, relates in particular to railway and loads and unloads oil filling riser with tank car light oil.
Be used to load and transport the truck tanker of lightweight finished fuel or highly volatile chemical at present, tank car, ship and other container need aspirate with oil pump when the bottom drain hole is not set, especially the loading and unloading oil filling riser that tank car is unloaded used of railway is when temperature is higher, the saturated vapor pressure of lightweight finished fuel or highly volatile chemical is very low, and it is higher in the temperature of suction channel, the vertex vapour lock of oil filling riser is gentle blocks up because the evaporation of material causes in the pipeline, existing band oil filling riser oil pump can't aspirate material, existing oil filling riser just link to each other with the oil pump suction power at present unload this be not provided with bottom drain hole lightweight finished fuel or highly volatile chemical adopt following several method or device often:
The one, vacuum pump adds sebific duct unloads, and working strength of workers is big, and unsafe factor is many; It two is to cooperate the oil pump of band oil filling riser to aspirate by pneumatic submersible pump to unload, but in order to ensure safety, pneumatic submersible pump needs nitrogen as power, but nitrogen cost height, the consumption of unloading is big, whenever unload a joint tank car and need consume 120-180 cube nitrogen approximately when temperature is higher, and the maintenance load of submersible pump being big, can't work in the place of no nitrogen; Also useful hydraulic pressure submersible pump because hydraulic may even the meeting of leakage contaminated material take place easily with oily, causes raw-material loss as the unloading unit of auxiliary power.More than the device or need auxiliary device, perhaps need source nitrogen, then can't unload as not possessing above-mentioned condition, as cause overstocking of train tank car, not only influence the supply of production material, but also influenced the traffic control of train greatly, and cause enormous economic loss can for the unit of unloading.
The purpose of this utility model is: a kind of economy, efficient, the safe oil filling riser of unloading are provided, are particularly useful for the unloading of truck tanker, tank car at shipment lightweight finished fuel or highly volatile chemical.
The purpose of this utility model is achieved in that a kind of oil filling riser of unloading, comprise that suction pipe, the straight tube that links to each other with suction pipe, swing pipe are connected with outlet conduit, between straight tube and the swing pipe active joint is arranged, on swing pipe, be provided with catch gears such as comprising cramp bar, support pad and handle, it is characterized in that in suction pipe and straight tube, being provided with the tube-shaped sputtering blwr, described tube-shaped sputtering blwr connects counter flow pipe, connect material exit or kinetic pump by counter flow pipe, spray blwr for be provided with nozzle in the end of counter flow pipe to the logistics direction.
Spray blwr and be essentially a counter flow pipe, utilize the material that refluxes to obtain pressure, be provided with inside nozzle in the end of counter flow pipe, and be 4 double helix formula nozzles, when having unloaded vapour lock, upwards spray, make when unloading and change malleation into, thereby overcome air-resistance phenomenon because of vapour lock produces negative pressure.
The utility model is obtained to spray power from connecting material exit or kinetic pump by counter flow pipe, especially utilizes the flow pressure of material own to overcome vapour lock, though the main net effciency that transports pump is had certain influence, can guarantee the main pump normal operation.
Suction capactity of the present utility model can guarantee at bottom pasta width below 400mm, can recover the normal operation of oil filling riser when the oil filling riser cutout occurring in 1-2 minute by the drainage of injection blwr; Spray the operation pressure of blwr and only need draw 0.08-0.15Mpa, need not the nitrogen source of the gas is used as power, do not need other medium source that is used as power, need not increase productive costs, safe and reliable, need not maintenance substantially, as long as increase some pipelines, and, can avoid air-resistance phenomenon fully through the test of crane position on the railway.The utility model is particularly useful for the oil filling riser of unloading of train tank car, is used to aspirate unload mol wt less volatile inflammable and explosive again alcohols, ester class, ketone, aldehydes, hydro carbons, aromatic hydrocarbons material.
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment:
Fig. 1 is the utility model structural representation
As shown in the figure, the oil filling riser of unloading, comprise suction pipe 1, the straight tube 2 that links to each other with suction pipe, the swing pipe 3 that links to each other with straight tube, the outlet conduit of swing pipe 3 and material is connected, active joint 4 is arranged between straight tube and the swing pipe, on swing pipe, be provided with and comprise cramp bar 5, the catch gear that support pad 6 and handle 7 etc. constitute, be provided with the tube-shaped sputtering blwr at straight tube inner suction pipe oral area, described tube-shaped sputtering blwr 8 connects the main pump exit by counter flow pipe 9 and obtains to spray power and introduce in the suction pipe, the end outlet of spraying blwr and be counter flow pipe for the nozzle of Flow of Goods and Materials equidirectional, jet expansion is unique outlet of counter flow pipe, the pressure that obtains from counter flow pipe all is used to overcome vapour lock, the spout of nozzle is an inclination angle vertically upward or slightly, the inwall of nozzle is made helix line, and the rifling of similar bore makes material that jet be arranged, can affact tight lock part far away, more effective than the straight hole.Nozzle be formed in counter flow pipe around, and 3-6 spout that makes progress arranged, and counter flow pipe also can be by being connected with kinetic pump and working when needed, and spout is exerted pressure to the vapour lock place, overcome the vapour lock of locking highest point, make the negative pressure that produces because of vapour lock when unloading change malleation into.
