From the above description, the beneficial effects of the utility model are as follows: in order to prevent the liquid material storage tank from entering the tank body 1 during discharging, the structure of pumping out the material by using a water pump in the conventional technology is replaced by an air inlet pipeline 4 for filling nitrogen into the tank body 1; the material is pressed out of the tank body 1 by the pressure of nitrogen.
The protection pipeline 5 prevents the air pressure in the tank body 1 from being too large to damage the tightness of the tank body 1, and prevents air from entering the tank body 1 when the air pressure in the tank body 1 is lower under certain discharging conditions.
Further, the device also comprises a liquid level meter 8 and a controller; the liquid level meter 8 is arranged on the tank body 1, the valves 6 are electrically controlled, the controllers are respectively connected with the valves 6 in a communication mode, and the controllers are connected with the liquid level meter 8 in a communication mode.
As can be seen from the above description, the liquid level meter 8 measures the reserve of the material in the tank body 1, and when the reserve of the material is too high, the liquid level meter 8 controls the valve 6 of the air inlet pipeline 4 and the discharge pipeline 3 to be opened and controls the valve 6 of the feed pipeline 2 to be closed through the controller.
Furthermore, the air inlet pipeline 4 and the protection pipeline 5 are respectively provided with a one-way valve.
As is apparent from the above description, the check valve prevents the reverse flow of the gas in the intake pipe 4 and the protection pipe 5.
Further, the device also comprises an exhaust pipeline 9, wherein the exhaust pipeline 9 is connected to the top of the tank body 1, and a stop valve and a one-way valve are arranged in the exhaust pipeline 9.
As can be seen from the above description, the exhaust pipeline 9 is used to discharge the material volatilized as gas periodically, so as to avoid the material volatilized as gas from being discharged from the protection pipeline 5 to the external environment and polluting the external environment.
Further, the device also comprises a pressure sensor 10 and a display; the pressure sensor 10 is arranged at the top of the inner wall of the tank body 1, the display is arranged on the outer surface of the tank body 1, and the display is in communication connection with the pressure sensor 10.
From the above description, the pressure sensor 10 transmits the pressure information in the tank body 1 to the staff via the display, so that the staff can take corresponding measures when the pressure is too high.
Further, the device also comprises a nitrogen tank and an air pump; the nitrogen tank is communicated with the tank body 1 through an air inlet pipeline 4, and the air pump is connected to the air inlet pipeline 4.
As can be seen from the above description, the arrangement provides a structure in which nitrogen gas pressurizes the top of the tank body 1, so that the nitrogen gas is sufficiently pressure-reduced to be discharged out of the discharge pipe 3.
