Abstract
Description
Technical Field
[0001] The utility model relates to the field of chemical drug production protection, in particular to a personnel safety protection device for chemical drug production. Background Art
[0002] During the production of chemicals, some chemical reactions may release harmful gases, which can cause damage to the respiratory system of production personnel if not handled properly. In addition, some chemicals may remain in equipment or work areas during processing, which may cause skin irritation, poisoning or even more serious health problems if people come into direct contact with them.
[0003] After searching the Chinese patent document with the announcement number CN218501677U, a personnel safety protection device for chemical drug production is disclosed; it includes a box body, an air intake pipe, an air guide, a transmission shaft, a stirring blade, a boost pipe, a hydraulic cylinder, a piston block, a one-way valve, a vent pipe, a motor, a bevel gear, a partition, a brush bar, a gear ring, a gear, a drain pipe, a valve, and an exhaust port. The hydraulic cylinder is controlled to reciprocate and extend, so that the toxic gas in the air intake pipe is drawn into the boost pipe, and then the gas in the boost pipe is pushed into the air guide pipe. When the pressure of the gas in the air guide pipe is greater than the water pressure, the gas will enter the dissolved liquid and mix with the dissolved liquid. The motor is started to drive the stirring blade outside the transmission shaft to revolve and rotate at the same time, and the two stirring blades rotate in opposite directions, so that the harmful substances in the toxic gas are fully mixed with the dissolved liquid.
[0004] This patent solves the problem that existing chemical drugs will produce toxic gases during production, which will cause damage to the health of production personnel, and therefore the toxic gases need to be fully purified. However, when the device is in use, the solvent dissolves the toxic gas. Therefore, although the stirring rod can stir the solvent, there is only a single air inlet, which increases the reaction time during dissolution, thereby reducing the dissolution efficiency of the device. Utility Model Content
