Accompanying drawing explanation
Fig. 1 is the structural principle schematic diagram of the conventional negative pressure device for storing liquid of chemical process;
Fig. 2 is structural principle schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 2, a kind of negative pressure device for storing liquid comprises retort 1, liquid container 2, collecting pipe 3, collecting pipe valve 4, breathing pipe 5, exhaust tube 6, gas valve 7, evacuating valve 8, liquid-discharging tube 9, outlet pipe 10, liquid-discharging tube valve 11 and exhaust valve 12.
The bottom of retort 1 is connected by collecting pipe 3 with the top of liquid container 2, and collecting pipe 3 is provided with collecting pipe valve 4; The top of retort 1 is connected with one end of breathing pipe 5, and the other end of breathing pipe 5 is connected with one end of exhaust tube 6, and the other end of exhaust tube 6 is connected with the top of liquid container 2; Breathing pipe 5 is provided with gas valve 7, and exhaust tube 6 is provided with evacuating valve 8; The sidewall bottom of liquid container 2 is communicated with one end of liquid-discharging tube 9, and top side wall is communicated with one end of outlet pipe 10, and the other end of the other end of liquid-discharging tube 9 and outlet pipe 10 is open setting all; Liquid-discharging tube 9 is provided with liquid-discharging tube valve 11, and outlet pipe 10 is provided with exhaust valve 12.
The working principle of this negative pressure device for storing liquid:
The liquid producing in retort 1 enters liquid container 2 by collecting pipe 3, and when valve 7 is opened, breathing pipe 5 conductings, are consistent the gas pressure of retort 1 and liquid container 2, and exhaust tube 6 is for finding time to liquid container 2.When evacuating valve 8 is closed, collecting pipe valve 4, gas valve 7, liquid-discharging tube valve 11 and exhaust valve 12 are used in combination can realize several functions: when exhaust valve 12 is opened, can exit to liquid container 2, destroy negative pressure in tank, then can open liquid-discharging tube valve 11 liquid in tank is discharged, now collecting pipe valve 4, gas valve 7 are closed and are guaranteed that retort normally works; When collecting pipe valve 4, gas valve 7 are opened, liquid container 2 receives the liquid of retort 1, and now liquid-discharging tube valve 11 and exhaust valve 12 are closed.When liquid-discharging tube valve 11 is closed, during all the other valve opens, can to whole system, inflate by exhaust tube 6.When evacuating valve 8 is opened, during other valve closings, can utilize outside negative pressure pump to find time to liquid container 2.
One end of breathing pipe 5 is arranged on the top of retort 1, and one end of exhaust tube 6 is arranged on the top of liquid container 2, avoids the liquid regions of retort 1 and liquid container 2, prevents that liquid or other materials from entering breathing pipe 5 or exhaust tube 6 blocking pipelines.Being used in conjunction with of breathing pipe 5 and exhaust tube 6, can to retort 1 and liquid container 2, find time simultaneously, thoroughly avoided hydrops obstruction in collecting pipe 3 to cause the shortcoming that cannot find time to liquid container 2, be also conducive to guarantee that retort 1 is consistent with the air pressure between liquid container 2 simultaneously.Exhaust tube 6, for external exhaust pipe, is found time liquid container 2 when opening evacuating valve 8 after liquid container 2 evacuation of liquid, has avoided the pressure surge problem in retort 1.Being used in conjunction with of collecting pipe valve 4, gas valve 7, liquid-discharging tube valve 11 and exhaust valve 12, can be under the non-stop condition of the interior technique of retort 1, realize the interior process liquid real-time collecting of liquid container 2 and discharge in real time, therefore liquid container 2 can be realized miniaturization.
