Detailed Description

The invention is further explained below with reference to the drawings and examples.

All the orientations referred to in the present specification are based on the orientations shown in the drawings, and only represent relative positional relationships, not absolute positional relationships.

As shown in fig. 1, fig. 2, fig. 3 and fig. 4, a bromine storage tank comprises a tank body 1, the tank body 1 is made of steel, the inner wall of the tank body 1 is lined with enamel or polytetrafluoroethylene or lead, a feed inlet 11 and an exhaust outlet 12 are arranged above the tank body 1, a protective cover 2 is arranged outside the feed inlet 11 and the exhaust outlet 12, the protective cover 2 is fixedly installed on the tank body 1 in a sealing manner, an air outlet 21 and a stub bar port 22 are arranged on the protective cover 2, the stub bar port 22 is arranged opposite to the feed inlet 11, an induced draft fan is arranged on the air outlet 21, a pressure control valve 121 is arranged on the exhaust outlet 12, a switch assembly 3 is fixedly installed in the feed inlet 11, the switch assembly 3 comprises an assembly body 31, a plunger 32 and a reset spring 33, a liquid inlet channel 311 is arranged in the center of the assembly body 31, an upper step surface 312 and a lower step surface 313 are arranged in the liquid inlet channel 311, the plunger 32 is positioned between the upper step surface 312 and the lower step surface 313, and can slide up and down along the liquid inlet channel 311, a return spring 33 is arranged between the lower end of the plunger 32 and the lower step surface 313, the upper end of the plunger 32 is pressed against the upper step surface 312 by the return spring 33, a overflowing channel 321 is arranged in the plunger 32, and the bottom of the overflowing channel 321 is connected with the inside of the tank body 1. A liquid storage cavity 34 is defined between the upper step surface 312 and the side wall of the plunger 32, an overflowing hole 322 is formed in the side wall of the plunger 32, and the overflowing hole 322 is communicated with the overflowing channel 321 and the liquid storage cavity 34. When the plunger 32 leaves the upper step surface 312, the liquid inlet channel 311 is opened, and bromine can enter the liquid storage cavity 34 from the liquid inlet channel 311, then enter the overflowing channel 321 through the flow hole 322 and then enter the interior of the tank body 1.

The plunger 32 is provided with a trigger bar 323, the trigger bar 323 is in a shape of [ shape, the vertical side of the [ shape is inserted into the assembly body 31 and slides up and down along the assembly body 31, the horizontal side of the [ shape bottom is positioned at the bottom of the upper step surface 312 and fixed on the plunger 32, the horizontal side of the [ shape upper part passes through the assembly body 31 and extends into the liquid inlet channel 311, and the assembly body 31 is provided with an avoiding groove 314 for the vertical sliding of the [ shape upper part horizontal side. The stub bar 4 is fixedly connected to a tank car or other devices, the stub bar 4 passes through the stub bar opening 22 and then is inserted into the liquid inlet channel 311, when the bottom of the stub bar 4 contacts the upper end of the trigger bar 323 and pushes the trigger bar 323 to slide downwards, the trigger bar 323 pushes the plunger 32 to move downwards so as to be separated from the upper step surface 312, and therefore the liquid inlet channel 311 is communicated with the overflowing channel 321, and filling of bromine liquid is achieved.

In order that the plunger 32 can be stably lowered when the trigger lever 323 pushes the plunger 32, four sets of the trigger levers are uniformly arranged around the plunger 32.

After filling, the stub bar 4 stops filling, and when all bromine remaining in the stub bar 4 and above the plunger 32 enters the tank body 1, the stub bar 4 exits, so that the trigger bar 323 loses external force, and the plunger 32 abuts against the upper step surface 312 under the action of spring force, thereby realizing sealing. The trigger bar 323 serves both to force the plunger 32 open and to guide it.

The tank body 1 is also provided with a nitrogen inlet 13. The nitrogen inlet 13 is communicated with a nitrogen machine, and nitrogen can be introduced into the tank body 1 through the nitrogen machine so as to adjust the air pressure in the tank body 1 and dilute the air in the tank body 1.
