【Specific embodiment】
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
With reference to Fig. 1, a kind of for alcohol reactive magnesium plus magnesium chips device, including feeding device and nitrogen replaceable equipment, described
Feeding device includes butterfly valve seal lid 8, and feed butterfly valve 7, and cone feed bin 6 also includes stainless with what 6 lower end of cone feed bin was connected
Steel feeding tube 4, rustless steel feeding tube 4 is connected with the discharge duct 13 of nitrogen replaceable equipment.
Described nitrogen replaceable equipment includes discharge duct 13 and connected lateral 14, wherein on discharge duct 13 according to
Secondary setting piping filter 9, pressure vacuum gauge 10 and vacuum valve 11, arrange nitrogen valve 12 on lateral 14.
The flanged (FLGD) glass being sequentially connected is set on described rustless steel feeding tube 4 cup 3 and charging ball valve 2 is regarded, no
4 its lower end of rust steel feeding tube is connected with reactor 1.
In being embodied as, the workflow of the present invention is as follows：
Feed intake in production process in magnesium alkoxide, when solid magnesium chips will be added, ball valve 5 is opened, other valves are in closing shape
State, opens vacuum valve 11, and feeding device evacuation when pressure vacuum gauge is -0.1Mpa, is closed vacuum valve 11, opens nitrogen
Valve 12 slowly enters nitrogen, when pressure vacuum gauge is 0.1Mpa, closes nitrogen valve 12；Vacuum valve 11 is then turned on, feeding device is taken out
