Description

Technical Field

[0002] Printing ink is an essential material in the printing industry. Ink is a colloidal substance mixed with a binder, a pigment and an auxiliary agent. The solvent (such as ethanol, ethyl acetate, etc.) as a binder is the main component of printing ink. The performance of the solvent directly affects the performance of the ink, so the reasonable use of the solvent is directly related to the quality and output of printed products. Printing solvents are volatile liquids, generally flammable and explosive, and safety protection is particularly important during storage and distribution.

[0003] In the prior art, the solvent is delivered to the solvent storage tank in the storage room by an external tank truck. The storage room is equipped with a solvent pump. When the solvent is used, the solvent is filled into the transfer tank through the solvent pump and sent to the production workshop for use. Safety protection is missing. Summary of the invention

[0005] By adopting the above technical scheme, when filling the solvent, the operator connects the transfer tank to the interface of the electromagnetic explosion-proof valve in the filling area, and then exits the storage room and opens the electromagnetic explosion-proof valve through the filling operation mechanism for filling. After normal filling is completed, the electromagnetic explosion-proof valve is closed and then enters the storage room to take away the transfer tank; when a leakage accident occurs, the combustible gas concentration detection alarm device will sound, the electromagnetic explosion-proof valve will be closed and the explosion-proof ventilation mechanism will be started at the same time, until the combustible gas concentration drops to a safe level, and personnel can enter; when a fire occurs, the automatic fire alarm system will work, and the fire alarm controller will send a signal to the lifting mechanism of the fire hood, the fire hood will be lowered, and the bottom hood opening will be nested in the sealing groove, the dry powder fire extinguisher will work, the fire risk will be extinguished, and the disaster will be effectively prevented from expanding.
