Description
Technical field
The present invention relates to tank car field, particularly relate to a kind of non-pressure tank car on unload pumping device.
Background technology:
The current tank car of China, tank body top is equipped with the liquid suction pipe 10 at blast pipe and straight-through tank base liquid trap place, sees Fig. 1, is mainly used in drawing liquid car unloading operation, should blast pipe 11 and liquid suction pipe blind flange be closed tight during vehicle normally runs, avoid medium in tank to leak.
Load onto on existing and unload drawing liquid assembling and have following shortcoming: structure function shortcoming: the gas-phase space pressure imbalance 1) in tank in gas-phase space pressure and liquid suction pipe.Tank body is after being exposed to the sun, and gas-phase space pressure increase in tank, when liquid suction pipe blind flange is poorly sealed, medium is forced out by the liquid suction pipe inserting liquid Space.2) avoid liquid suction pipe top meteorological spatial pressure increase during entrucking, all must open liquid suction pipe blind flange.Cost, quality shortcoming: 1) former unloading pipe connection, blind flange all adopt casting method manufacture, foundry technique is complicated, and cost is high.2) there is mass defect in casting, and when installing on fortune dress corrosive liquid (acid, alkali) tank car, foundry defect is easy to cause corrosion aggravation.
Summary of the invention
In order to solve technical matters existing in background technology, the present invention proposes a kind of tank car air intake pumping device, pumping device structure is designed to air intake drawing liquid Contiuum type structure, disjunctor air intake pumping device is arranged on base by flange, and gas-phase space in tank is communicated with gas-phase space in liquid suction pipe.
Technical solution of the present invention is: tank car air intake pumping device, is characterized in that: air intake pumping device comprises base, the base flange be connected with base, base blind flange, blast pipe, liquid suction pipe and coupling flange, coupling flange lid; Described blast pipe, liquid suction pipe are welded as entirety with coupling flange base blind flange respectively, be fixedly connected with base flange again, the through whole base of liquid suction pipe, in tank, gas-phase space is communicated with gas-phase space in liquid suction pipe, and coupling flange is arranged on the upper end of blast pipe and liquid suction pipe.
Above-mentioned coupling flange covers and arranges communicating passage capping, arranges the communicating passage that two ends are connected with blast pipe and liquid suction pipe respectively in coupling flange lid.
Above-mentioned coupling flange and coupling flange lid are by loose joint bolt and chain connection.
Above-mentioned communicating passage capping and coupling flange lid are fixedly connected by welding.
Above-mentioned coupling flange lid and coupling flange arrange seal ring in the junction of blast pipe, liquid suction pipe respectively.
Above-mentioned base flange connects base blind flange, between base blind flange and base flange, seal ring is set.
The beneficial effect of air intake pumping device of the present invention:
Structural advantages:
1) be communicated with tank body meteorological spatial in liquid suction pipe, with liquid level difference phenomenon in tank body in thorough elimination liquid suction pipe.User use operation lack of standardization, liquid suction pipe coupling flange cap bolt uneven fastening time, also can not liquid suction pipe flange produce the phenomenon of leakage.
2) blast pipe, liquid suction pipe are welded on a base blind flange, are arranged on flange, reduce the number of openings on tank body.
Quality, cost advantages:
1) change original cast type accessory, avoid casting the mass defect caused.
2) (contact) all accessories except section bar with conveying medium and all adopt the wrought form processing such as steel plate, save casting tooling cost.
Service advantages:
1) blast pipe liquid suction pipe Contiuum type structure, saves when entrucking and opens liquid suction pipe coupling flange lid operation.
2) air intake pumping device, unlatching operation is easy, and also minimizing operator opens the danger that liquid suction pipe (acid, alkali lye) corrodes.
