Abstract
A kind of plate centrifuge adds nitrogen explosion-protection equipment, it is characterized in that being made up of plate centrifuge, nitrogen inlet, nitrogen delivery pipe, plate centrifuge cover, plate centrifuge rotary drum, plate centrifuge outer wall, material inlet, material outlet, valve.Nitrogen delivery pipe is arranged on plate centrifuge cover；Material outlet is arranged on below plate centrifuge；Material inlet is arranged on plate centrifuge cover；Valve is separately mounted to nitrogen inlet and material inlet lower section.Device installation is simple, safe and practical；Both it can prevent plate centrifuge from exploding, bulk drug in plate centrifuge can be avoided to be oxidized again.
Description
Technical field
A kind of explosion-protection equipment is the utility model is related to, especially a kind of plate centrifuge adds nitrogen explosion-protection equipment.
Background technology
The production of nasmil bulk drug, it is that first Cromoglycic acid diethylester, sodium acid carbonate are put into added with alcohol solvent
In crystallizing tank, then by crystallizing tank various raw materials carry out sufficiently stir, heat, so as to form nasmil raw material
Medicine.Then activated carbon is added in nasmil bulk drug and decolourized.After standing four hours, added into crystallizing tank cold
Freeze salt solution to be cooled.When temperature is reduced to less than 5 degree, stopping chilled brine cooling.Now the nasmil in crystallizing tank is former
Material medicine just forms crystalline solid, you can is sent to from drain hole output in 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 to containing inflammable, explosive solvent in bulk drug, 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 potential safety hazard be present；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, there is air in plate centrifuge：One, which carrys out plate centrifuge, easily sends out
, potential safety hazard be present in raw blast；Two, which carry out in plate centrifuge bulk drug, is easily oxidized, the problem of influenceing bulk drug quality, this reality
It is to disclose a kind of plate centrifuge to add nitrogen explosion-protection equipment with new purpose.
Technical scheme is used by a kind of plate centrifuge of the utility model adds nitrogen explosion-protection equipment：In plate centrifuge machine
Cover installation one plus nitrogen device.Add nitrogen device that nitrogen is transported in plate centrifuge.Due to nitrogen lta, nitrogen can
Air in plate centrifuge is extruded.Due to that will not be exploded without air, plate centrifuge 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, opens the valve in nitrogen delivery pipe.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, it can effectively avoid plate centrifuge that the bulk drug in blast and plate centrifuge occurs by oxygen
Change.
A kind of plate centrifuge of the utility model adds the beneficial effect of nitrogen explosion-protection equipment to be：Device installation is simple, and safety is real
With；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 that a kind of plate centrifuge of the utility model adds nitrogen explosion-protection equipment.
In figure, 1, plate centrifuge；2nd, nitrogen inlet；3rd, nitrogen delivery pipe；4th, plate centrifuge cover；5th, flat board centrifuges
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, opens the valve 9 in nitrogen delivery pipe 3.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 effectively avoided to occur in blast and plate centrifuge 1
Bulk drug be oxidized.
