Description

Technical Field

[0001] The utility model relates to the technical field of triethyl storage tanks, in particular to a triethyl storage tank with a moisture-proof structure. Background Art

[0002] Triethylaluminum trichloride is a common chemical raw material, mostly used in synthesis reaction intermediates, polymerization reaction catalysts and aromatic derivative ammonia addition catalysts. In industrial production, it is mostly produced by the reaction of aluminum and ethyl chloride. Triethylaluminum trichloride is prone to spontaneous combustion when in contact with air, thus posing a major safety hazard.

[0003] The existing transfer storage tank adopts a one-layer design. When the tank leaks, triethylaluminum trichloride directly contacts with the air and burns, which has poor safety.

[0004] For example, a triethylaluminum trichloride transport storage tank disclosed in Chinese patent CN217075654U has a simple design, low cost and is easy to manufacture. Secondly, by filling the interlayer with nitrogen and pressurizing it, when the inner tank leaks, the pressure change signal generated is converted into an alarm signal, so that the leak is checked in time to prevent direct leakage into the air to form a fire or explosion accident. At the same time, when nitrogen leaks from the outer tank, the pressure alarm will also sound an alarm, so that workers can repair it in time to eliminate the safety hazard of nitrogen loss and insurability.

[0005] However, when storing triethylaluminum, the device is unable to process the moisture inside the storage tank, causing a violent reaction when the moisture comes into contact with triethylaluminum, causing safety issues.

[0006] For this reason we urgently need to provide a triethyl storage tank with a moisture-proof structure. Utility Model Content

[0011] Preferably, the water absorption unit comprises a placement box and a desiccant, wherein the placement box is fixedly installed at the front and rear ends of the storage tank, and the desiccant is installed inside the placement box.

[0012] Preferably, the end of the hose away from the hot air blower is connected to the connecting pipe, and the hot air generated by the hot air blower enters the inside of the connecting pipe along the hose and then dissipates from the air outlet to dry the humid air inside the storage tank.

[0013] Preferably, the disc is provided with an internal thread matched with the screw rod, and the disc and the screw rod cooperate to make the disc drive the air outlet to move up and down, so as to dry different positions inside the storage tank and make the drying more uniform.

[0015] Preferably, the water absorption units are symmetrically distributed at the front and rear ends of the upper end inside the storage tank, and absorb the moisture stored in the triethylaluminum through the desiccant.

[0016] Preferably, a mounting hole is provided inside the fixing block, the connecting pipe is installed inside the mounting hole, and the connecting pipe is fixed to the disc through the mounting hole.
