Description
Technical field
The present invention relates to a kind of explosion-protection equipment, especially a kind of plate centrifuge adds nitrogen explosion-protection equipment.
Background technology
The production of nasmil bulk drug, is that first Cromoglycic acid diethylester, sodium acid carbonate are put into added with alcohol solvent
In crystallizing tank, then by various raw materials progress sufficiently stirring, the heating in crystallizing tank, so as to form nasmil raw material
Medicine.Then activated carbon is added in nasmil bulk drug and decolourized.Stand after four hours, added into crystallizing tank cold
Freeze salt solution to be cooled.When temperature is reduced to less than 5 degree, stop chilled brine cooling.Nasmil now in crystallizing tank is former
Material medicine just forms crystalline solid, you can is exported from drain hole in being sent to plate centrifuge and carries out solid and liquid separation.At present, flat board from
Scheming to bulk drug crystalline solid carry out solid and liquid separation when, due in bulk drug contain inflammable, explosive solvent, when flat board from
When scheming rotates at a high speed, there is air in plate centrifuge：One, which carrys out plate centrifuge, easily explodes, and there is potential safety hazard；Two
Carry out bulk drug in plate centrifuge to be easily oxidized, influence the quality of bulk drug.The solution that this problem has never had.
The content of the invention
It is easy due to containing in bulk drug for current plate centrifuge when carrying out solid and liquid separation to bulk drug crystalline solid
Combustion, explosive solvent, when plate centrifuge rotates at a high speed, have air in plate centrifuge：One, which carrys out plate centrifuge, easily sends out
, there is potential safety hazard in raw blast；Two, which carry out bulk drug in plate centrifuge, is easily oxidized, the problem of influenceing bulk drug quality, this hair
Bright purpose is to disclose a kind of plate centrifuge plus nitrogen explosion-protection equipment.
The technical scheme that a kind of plate centrifuge of the present invention adds nitrogen explosion-protection equipment to be used is：In plate centrifuge cover
On install one plus nitrogen device additional.Plus nitrogen is transported in plate centrifuge by nitrogen device.Due to nitrogen lta, nitrogen can be by
Air extrusion in plate centrifuge.Because, without air, plate centrifuge will not explode in plate centrifuge.
A kind of plate centrifuge adds nitrogen explosion-protection equipment, it is characterized in that by plate centrifuge, nitrogen inlet, nitrogen delivery pipe,
Plate centrifuge cover, plate centrifuge rotary drum, plate centrifuge outer wall, material inlet, material outlet, valve composition.Nitrogen
Delivery pipe is arranged on plate centrifuge cover；Material outlet is arranged on below plate centrifuge；Material inlet is arranged on flat board
On centrifuge cover；Valve is separately mounted to nitrogen inlet and material inlet lower section.
When to carry out solid and liquid separation to bulk drug crystalline solid, bulk drug crystalline solid is sent to flat board from material inlet
In centrifuge.Plate centrifuge cover is covered, the valve in nitrogen delivery pipe is opened.Nitrogen is transported to flat board by nitrogen delivery pipe
In centrifuge.Due to nitrogen lta, nitrogen can extrude the air in plate centrifuge from material outlet.Plate centrifuge
After interior air is extruded by nitrogen, plate centrifuge can be prevented effectively from and occur blast and the bulk drug in plate centrifuge by oxygen
Change.
A kind of plate centrifuge of the present invention adds the beneficial effect of nitrogen explosion-protection equipment to be：Device installs simple, safe and practical；
Both it can prevent plate centrifuge from exploding, bulk drug in plate centrifuge can be avoided to be oxidized again.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of plate centrifuge of the invention plus nitrogen explosion-protection equipment.
In figure, 1, plate centrifuge；2nd, nitrogen inlet；3rd, nitrogen delivery pipe；4th, plate centrifuge cover；5th, flat board is centrifuged
Machine rotary drum；6th, plate centrifuge outer wall；7th, material inlet；8th, material outlet；9th, valve.
Embodiment
A kind of plate centrifuge adds nitrogen explosion-protection equipment, it is characterized in that by plate centrifuge 1, nitrogen inlet 2, nitrogen delivery pipe
3rd, plate centrifuge cover 4, plate centrifuge rotary drum 5, plate centrifuge outer wall 6, material inlet 7, material outlet 8,9 groups of valve
Into.Nitrogen delivery pipe 3 is arranged on plate centrifuge cover 4；Material outlet is arranged on the lower section of plate centrifuge 1；Material inlet
On plate centrifuge cover 4；Valve 9 is separately mounted to nitrogen inlet 2 and the lower section of material inlet 7.
When to carry out solid and liquid separation to bulk drug crystalline solid, bulk drug crystalline solid is sent to flat board from material inlet 7
In centrifuge 1.Plate centrifuge cover 4 is covered, the valve 9 in nitrogen delivery pipe 3 is opened.Nitrogen delivery pipe 3 conveys nitrogen
Into plate centrifuge 1.Due to nitrogen lta, nitrogen can extrude the air in plate centrifuge 1 from material outlet 8.
After air in plate centrifuge 1 is extruded by nitrogen, plate centrifuge 1 can be prevented effectively from and occurred in blast and plate centrifuge 1
Bulk drug be oxidized.
