Description
Technical field
The utility model relates to technical field of chemical, particularly relates to a kind of material storage tank that prevents and takes out flat device.
Background technology
At present, most of stock tank nitrogen preservation.In fill process, because tank body is sealing, needing to supplement from top to carrying out nitrogen in tank constantly, to ensure both to reach sealing, tank body internal pressure can be ensured again.But once nitrogen pressure reduces, or nitrogen supply (NS) disconnects, when namely not having nitrogen, seal and continue to take out the reasons such as material due to tank body, can cause forming negative pressure in tank body, tank skin can be taken out flat thereupon, causes accident easily to occur.
So, be necessary to provide a kind of material storage tank that prevents to take out flat device, can effective fender batch can, to overcome above-mentioned technological deficiency.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of material storage tank that prevents to take out flat device, can effective fender batch can, and to overcome, material storage tank in prior art is easily hemorrhage takes out the flat defect causing Peril Incident to occur.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of material storage tank that prevents is provided to take out flat device, described device comprises storage tank, U-tube and is arranged on the standpipe of described tank top, water is filled in described standpipe, the pressure of this water column is equal with the pressure in described storage tank, one open end of described U-tube stretches under water column liquid level through the sidewall of described standpipe, and another open end stretches in described storage tank; Described device also comprises ventilation flue, and one end of described ventilation flue communicates with the gas piping being communicated with material storage tank, and the other end extend in described storage tank.
Take out in flat device at the above-mentioned material storage tank that prevents, one end that described gas piping is communicated with nitrogen delivery end is provided with control cock, and the air pressure of described control cock setting is all equal with the air pressure in the hydraulic pressure in described standpipe and described storage tank and described material storage tank.
Take out in flat device at the above-mentioned material storage tank that prevents, described control cock is parallel with bypass disc.
Take out in flat device at the above-mentioned material storage tank that prevents, described ventilation flue is provided with air valve, and described air valve is open in usual.
Have employed technique scheme; the beneficial effects of the utility model are: compared with prior art; a kind of material storage tank that prevents of the present utility model takes out flat device; when material storage tank inside forms negative pressure, can in time air be extracted in material storage tank, can effectively prevent material storage tank from being taken out flat; prevent the generation of accident; and the danger factor reduced in production process, and then protect equipment, also reduce productive costs.
Accompanying drawing explanation
Fig. 1 is that the material storage tank that prevents of the utility model embodiment takes out the structural representation of flat device;
Wherein, 1 is storage tank, and 2 is U-tube, and 3 is standpipe, and 4 is ventilation flue, and 5 is material storage tank, and 6 is gas piping, and 7 is control cock, and 8 is bypass disc, and 9 is air valve.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but can not be used for limiting scope of the present utility model.
Fig. 1 is that the material storage tank that prevents of the utility model embodiment takes out the structural representation of flat device.
As shown in Figure 1, the material storage tank that prevents of the utility model embodiment takes out flat device, comprise storage tank 1, U-tube 2 and be arranged on the standpipe 3 at storage tank 1 top, water is filled in standpipe 3, the pressure of this water column is equal with the pressure in storage tank 1, one open end of U-tube 2 stretches under water column liquid level through the sidewall of standpipe 3, and another open end stretches in storage tank 1.This device also comprises ventilation flue 4, and one end of ventilation flue 4 communicates with the gas piping 6 being communicated with material storage tank 5, and the other end extend in storage tank 1.One end that gas piping 6 is communicated with nitrogen delivery end is provided with control cock 7, the air pressure that control cock 7 sets is all equal with the air pressure in the hydraulic pressure in standpipe 3 and storage tank 1 and material storage tank 5, control cock 7 is parallel with bypass disc 8, ventilation flue 4 is provided with air valve 9, and air valve 9 is open in usual.
In the present embodiment, more specifically, storage tank 1 tank deck is welded with the standpipe 3 higher than 50cm, standpipe 3 higher than storage tank 1 tank deck 45cm place arranges an inverted U-tube 2, one opening of U-tube 2 is deep in standpipe 3, 3cm at the bottom of distance pipe, another open end extend in storage tank 1, distance storage tank 1 tank deck 10cm place, 40cm deep water is injected by storage tank 1, because storage tank 1 and material storage tank 5 internal pressure are continuously 4KPa, it is 4KPa that nitrogen passes into pressure, water column like this keeps mutually permanent with pressure, now play sealing function, nitrogen can not enter storage tank 1, when nitrogen pressure is very low, or nitrogen supply (NS) disconnects, when namely there is no nitrogen, material storage tank 5 can reduce pressure because of continuing to be extracted material, now, the water column of 40cm is pumped in storage tank 1 by U-tube 2, due to much larger than the diameter of standpipe 3 of the diameter of storage tank 1, so water level is very low, now U-tube can continue suction air in storage tank 1, the air of suction is input in material storage tank 5 under suction function, material storage tank 5 tank skin is prevented to take out flat accident like this.
As mentioned above; a kind of material storage tank that prevents of the present utility model takes out flat device; when material storage tank inside forms negative pressure; can in time air be extracted in material storage tank; can effectively prevent material storage tank from being taken out flat, prevent the generation of accident, and reduce the danger factor in production process; and then protect equipment, also reduce productive costs.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, done all conversion, all drop within protection domain of the present utility model.
