[0020] Example 1

[0021] The invention discloses a sodium hydroxide solution storage device capable of automatically discharging liquid and filtering air. In order to prevent the storage device from reacting with the sodium hydroxide solution, plastic material is used.

[0022] The sodium hydroxide solution storage device of the present invention comprises a plastic shell 1 and a liquid outlet pipe 2; wherein the plastic shell 1 is divided into a liquid storage chamber I and an air filter chamber II arranged on the left and right by an integrally formed inner wall plate 3.

[0023] Specifically, a first one-way check valve 4 is installed at the bottom of the outer wall of the air filter chamber II, and the first one-way check valve 4 is connected to an external inflation device (not shown) for filling air into the entire sodium hydroxide solution storage device. A detachable plastic cover plate 5 is installed on the top of the air filter chamber II, and the plastic cover plate 5 is detachably and tightly connected and fixed to the outer wall and inner wall plate 3 of the air filter chamber II by screws 11, so as to facilitate the replacement of the air filter device in the air filter chamber. The inner surface of the plastic cover plate is also provided with a sealing gasket.

[0024] A second one-way check valve 6 is installed on the top of the inner wall plate 3 to introduce the filtered air into the liquid storage chamber; an air filter device is installed in the area between the first one-way check valve 4 and the second one-way check valve 6 in the air filter chamber. The air filter device includes a microporous filter plate 7 and a filter medium 8; wherein the microporous filter plate 7 is arranged at the top and bottom of the air filter chamber and is horizontally fixedly connected to the inner wall of the air filter chamber, and the filter medium 8 is distributed in the air filter chamber between the microporous filter plates. The filter medium 8 is preferably lime lime. Through the design of the microporous filter plate 7, a gas storage cavity can be formed at the top and bottom of the air filter chamber.

[0025] Preferably, there are two vertical partitions 9 between the outer wall and the inner wall plate 3 of the air filter chamber II; wherein, the partition 9 close to the outer wall is located on the upper section of the microporous filter plate 7 and is installed with a third one-way check valve 10; the partition close to the inner wall plate 3 is located on the lower section of the microporous filter plate 7 and is installed with a fourth one-way check valve 11. The plastic cover plate 5 is detachably and tightly connected to the inner wall plate 3, the outer wall and the partition 9 of the air filter chamber by screws 16. The preferred air filter chamber is a three-stage filter device, and its structural design can further improve the filtering quality of the air.

[0026] The top of the liquid storage chamber I is provided with a liquid inlet for adding sodium hydroxide solution into the liquid storage chamber I. A sealing cover 12 is installed on the liquid inlet. The sealing cover 12 is a threaded cover and is threadedly connected to the liquid inlet. The bottom surface of the sealing cover 12 is located inside the liquid inlet and is also provided with a T-shaped leakproof component 13 to further improve the safety performance of sealing and leakproofing. The maximum liquid level of the sodium hydroxide solution in the liquid storage chamber is located below the second one-way check valve 6.

[0027] One end of the liquid outlet pipe 2 is inserted into the inner bottom of the liquid storage chamber I, and the other end thereof extends out of the liquid storage chamber I. The portion of the liquid outlet pipe 2 extending out of the liquid storage chamber I is bent downward, and a fifth one-way check valve 14 and a spiral valve 15 are sequentially installed on the liquid outlet pipe 2 along the liquid outlet direction.

[0028] The working principle of the sodium hydroxide solution storage device for automatically discharging liquid and filtering air is as follows: the sodium hydroxide solution is stored in a liquid storage chamber through a liquid inlet, and when in use, the spiral valve on the liquid outlet pipe and the externally connected gas charging device are opened, and at this time, the externally connected gas charging device charges air into the bottom of the air filter chamber through a first one-way check valve, and the air passes through a filter medium for three times in the air filter chamber under the guiding action of a third one-way check valve and a fourth one-way check valve, and finally enters the liquid storage chamber through a second one-way check valve, and the sodium hydroxide solution in the sealed liquid storage chamber automatically flows out through the liquid outlet pipe under the pressure of the air, thereby completing the automatic liquid discharging and taking, and in the whole process, the sodium hydroxide solution does not directly contact with the air, thereby ensuring the quality of the sodium hydroxide solution.

[0029] The present invention discloses a sodium hydroxide solution storage device capable of automatically discharging liquid and filtering air. The liquid storage chamber and the air filter chamber are designed to be integrally connected, thereby realizing automatic liquid discharge on the one hand, and making the sodium hydroxide solution only contact with the filtered air in the whole process from loading into the storage device to using the sodium hydroxide solution, thereby ensuring the quality of the sodium hydroxide solution. The multi-stage air filter chamber of the present invention ensures the filtering effect of the air, thereby enabling the sodium hydroxide solution in the storage device to be used for a long time without deterioration. The present invention is easy to use. When in use, it is only necessary to open the spiral valve on the liquid outlet pipe and start the gas charging device to realize automatic liquid discharge, thereby making the use and storage of the sodium hydroxide solution very convenient.
