Abstract
The utility model relates to an acid unloading device for a tank wagon for transporting acid, comprising a pump 5 and a liquid suction tube 16 communicated with an acid tank wagon. The utility model is characterized in that the lower part of the pump 5 is provided with a tank 8; the upper part of the pump is connected with a liquid outlet tube provided with controlling valves 10, 4; a reflux tube 14 arranged between the two controlling valves 10, 4; the outlets of a jet tube 11 and the liquid suction tube 16 are respectively inserted in a negative-pressure tube 9 in the tank. The device has the advantages of convenient operation, safety, reliability and low maintenance cost. The acid in the tank wagon and in a pipe passage can be unloaded thoroughly. The utility model can avoid accidents.
Description
The utility model relates to a kind of device that unloads liquid, particularly a kind ofly transports acid with the sour device of unloading of tank car.
The Chinese large-sized coke-oven plant is because the sulfuric acid consumption is big, and generally by railway acid tank car transportation, this is discharged into problem in the sour storage tank with regard to relating to the acid that needs to solve in the tank car, adopts compound vacuum channel process, vacuum pump method or pressurized air to unload acid system at present usually.For compound vacuum channel process, the horizontal groove up and down that whole device is equated by two volumes, pump and storage tank are formed, and during operation, the sulfuric acid that will go up earlier in the groove is put into down groove, following groove injects pump chamber, primer pump then, the acid in the following groove is extracted out rapidly, make its head room and with wherein form vacuum, so the siphonage necessary condition forms, pump can continuously draw off acid; Against vacuum pump method, it is made up of vacuum pump, sour pump, storage tank, during operation, starts vacuum pump earlier, 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 charged into tank car acid is extruded in the tank car but will accomplish that acid tank car pipe connecting flange is firm, pipeline system is tight.These unload not only complex operation of sour method, and because the leakage of pump need periodically be carried out large-area anti-corrosion treatment to terrace; Simultaneously, the emptying effectively of the acid in the pipeline, maintenance brings a lot of difficulties to pipeline, even the generation that causes the accident.
The purpose of this utility model is to overcome above-mentioned deficiency and provides a kind of tank car that utilizes siphon and jet strength that acid is drawn off from tank car inside to unload sour device.
The utility model is achieved in that tank car unloads sour device, the pipette that includes pump and be communicated with the acid tank car, it is characterized in that: groove is arranged below pump, be connected to drain pipe on the pump with two control cock, and two be connected to counter flow pipe on the drain pipe between the control cock, and the outlet of jet pipe and pipette is all in the negative pressure pipe in insertion groove; When using the utility model, primer pump is opened the prime control cock, makes acid solution in the acid tank car through pipette, the negative pressure pipe enters in the groove, and through pump, prime control cock counter flow pipe and jet pipe, negative pressure pipe formation circulating reflux, because the jet pipe effect forms negative pressure in the negative pressure pipe, make the acid solution in the acid tank car enter pipette rapidly, open back level control cock, the acid solution part that pumps is discharged through drain pipe, part is in the counter flow pipe return slot.
Because adopt above-mentioned tank car to unload sour device, safety of operation, reliable, easy can unload the acid in the tank car only; In groove, not only energy savings does not need periodically terrace to be carried out anti-corrosion treatment yet, reduces maintenance cost again for the many usefulness of one pump, the pump housing; Groove is in extreme lower position, behind the end of operation, and can be effectively with the spent acid emptying in the pipeline, the generation of stopping accident.
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1. acid tank car, 2. drain pipe, 3. drain pipe, 4. control cock, 5. pump, 6. feed tube, 7. valve, 8. groove, 9. negative pressure pipe, 10. control cock, 11. jet pipes, 12. control cock, 13. control cock, 14. counter flow pipes, 15. control cock, 16. pipette.
Below in conjunction with drawings and Examples the utility model is further described:
As shown in Figure 1: the utility model includes pump 5 and is communicated with pipette 16 with the acid tank car, it is characterized in that groove 8 is arranged below pump, be connected to the drain pipe 2,3 of band control cock 10,4 on the pump, be connected to counter flow pipe 14 between control cock 10,4, the outlet of jet pipe and pipette is all in the negative pressure pipe 9 in insertion groove; For easy to use, reduce to pollute etc., groove can pre-buried underground formation underground tank; Nozzle exit is on the line of centers of pipette outlet, to improve jet pipe hydrojet effect; For more convenient operation, can control the acid solution liquid outlet quantity, on counter flow pipe, be provided with control cock 13, to close hour when control cock, the drain pipe liquid outlet quantity is big, on the contrary the drain pipe liquid outlet quantity reduces; Drain pipe can be with sour height and puts the drain pipe 2 that groove is communicated with, and directly to supply the user, also can be the drain pipe of connecting with sour storage tank 3, so that storage liquid is standby, can be connected to the feed tube of connecting with sour storage tank 6 on groove, so that directly use for the user or transfer storage liquid container.
