Abstract
An acid unloading device of a tank car is provided with an acid unloading crane pipe (1) capable of extending into the tank car (6) and an acid unloading pump (5), wherein the acid unloading crane pipe (1) is connected with the acid unloading pump (5) through a pipeline; an inlet valve (2) is arranged in front of an inlet of the acid unloading pump (5), and an outlet valve (4) is arranged behind an outlet of the acid unloading pump (5); and a water or pumped object pipeline (7) and a control valve (3) of the water or pumped object pipeline (7) are further connected onto a pipeline between the inlet valve (2) and the acid unloading pump (5). Compared with the existing acid unloading device provided with a vacuum system, the acid unloading device saves energy, reduces maintenance cost and leakage, and is easy and convenient to operate.
Description
Technical field
The utility model relates to a kind of device of unloading liquid, especially relates to a kind of from transporting the device that draws off acid solution in the tank car.
Background technology
The transportation of commercial acid is generally packed acid in the tank car, and by railway or road transport, from tank car acid being discharged in the sour storage tank has several different methods, usually adopts at present compound vacuum channel process, vacuum pump method or pressurized air to unload acid system.For compound vacuum channel process, the horizontal up and down groove that whole device is equated by two volumes, pump and storage tank form, and during operation, first the acid solution in the upper groove are put into lower groove, lower groove injects pump chamber, then start pump, the acid in the lower groove is extracted out rapidly, the upper groove formation vacuum that makes its head room and be attached thereto, so the necessary condition of siphonage forms, pump can continuously draw off acid; For the vacuum pump method, it is comprised of vacuum pump, sour pump, storage tank, during operation, starts first vacuum pump, after sour pump pump chamber is full of acid, stops vacuum pump, starts sour pump, and acid is drawn off from tank car; Unload acid system for pressurized air, pressurized air is filled with tank car acid is extruded in the tank car but will accomplishes that the pipe connecting flange of acid tank car is firm, pipeline system is tight.These unload not only complex operation of sour method, and vacuum or pressure system are easily destroyed, and the less stable of operation is especially for the acid of high concentration.
CN2205791Y discloses a kind of acid unloading device for tank wagon, the pipette that includes pump and be communicated with the acid tank car has groove below pump, be connected to the drain pipe with control cock on the pump, be connected to counter flow pipe between control cock, the outlet of jet pipe pipette is all in the negative tube in insertion groove.Although this device is easy and simple to handle, safe, reliable, device is complicated, and underground tank need be set, and control is complicated.
The utility model content
In order to overcome the defective of prior art, the technical problems to be solved in the utility model is: a kind of acid unloading device for tank wagon simple in structure, energy-conservation, easy and simple to handle is provided.
In order to solve the problems of the technologies described above, the acid unloading device for tank wagon that the utility model provides, the basic technical scheme of taking is: a kind of acid unloading device for tank wagon has the sour oil filling riser that unloads that can stretch in the tank car; Unload sour oil filling riser and unload sour pump by what pipeline was connected with described; Described unloading has imported valve before the sour pump inlet, has outlet valve after the outlet; At described imported valve and unload on the pipeline between the sour pump, also be connected with water or smoke conduit and by-pass valve control.
Preferably, the water of described acid unloading device for tank wagon or smoke conduit and be connected to the nadir of unloading pipeline before the sour pump.
Preferably, the water of described acid unloading device for tank wagon or smoke conduit and be connected with the clear water pipe network, or be connected with the high-order storage tank that extracts thing.
The beneficial effect that the utility model brings: the sour device that unloads that provides utilized water or smokes thing and get rid of the gas that unloads in sour pump and the pipeline in when start, make and unload sour oil filling riser and can form the siphon effect, thereby realize unloading sour operation, its dexterity simple in structure, simple to operation, the existing sour device of unloading of vacuum system that arranges is saved the energy, reduces maintenance cost, reduces and leaks.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, consists of the application's a part, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the utility model embodiment acid unloading device for tank wagon.
The specific embodiment
Acid unloading device for tank wagon as shown in Figure 1 unloads sour oil filling riser 1 and can stretch in the tank car 6 when unloading acid, can shift out in tank car after unsnatching acid; Unload sour oil filling riser 1 by pipeline with unload sour pump 5 and be connected, unload the pipeline that pipeline before sour pump 5 imports is provided with after imported valve 2, the outlet and be provided with outlet valve 4, be connected with water or smoke conduit 7 at imported valve 2 and the lowest point that unloads the pipeline between the sour pump 5, water or smoke conduit 7 and be provided with by-pass valve control 3, when the acid in the tank car can add entry when unloading acid, such as hydrochloric acid, water or smoke conduit 7 and be designed to be connected with clear water pipe network or the high-order storage tank that extracts thing; When the acid in the tank car can not add entry when unloading acid, such as sulfuric acid, water or smoke conduit 7 and be designed to be connected with the high-order storage tank that extracts thing.
During operation, to unload first sour oil filling riser 1 stretches in the tank car 6, make the inlet that unloads sour oil filling riser 1 be inserted into the bottom of tank car 6, close imported valve 2, after opening outlet valve 4, opening controlling valve door 3, with unload sour pump 5 and import and export near air scavenge in the pipeline, be full of liquid after, close outlet valve 4, open imported valve 2, imported valve 2 is discharged to the gas in the pipeline between the inlet that unloads sour oil filling riser 1, start and unload sour pump 5, open outlet valve 4, when unload acid normal after, closing control valve 3 continues to smoke acid solution in the tank car 6 to unsnatching.
The above only is preferred embodiment of the present utility model, and limits never in any form the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
