Abstract
Discharging device of a kind of crystallizing tank without spacing, without blind pipe, it is characterized in that being made up of crystallizing tank, drain hole, diaphragm valve, vomit pipe.Crystallizing tank is provided with drain hole；Drain hole is connected with diaphragm valve；Vomit pipe is connected with diaphragm valve.After bulk drug crystallization in crystallizing tank, diaphragm valve is opened, bulk drug is discharged from vomit pipe.Due to using diaphragm valve, without flange, crystallizing tank drain hole, without spacing, without blind pipe, does not result in diaphragm valve obstruction with diaphragm valve.
Description
Technical field
The present invention relates to a kind of discharging device, discharging device of especially a kind of crystallizing tank without spacing, without blind pipe.
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 centrifuge and carries out subsequent technique processing.At present, crystallizing tank is put
Material mouth is connected by flange, ball valve, flange, so as to cause the spacing for having 20 ㎝ between ball valve and crystallizing tank.Between this 20 ㎝
Away from interior, bulk drug can not be stirred, easy obstruction ball valve after crystallization.The solution that this problem has never had.
The content of the invention
For current, crystallizing tank drain hole is connected by flange → ball valve → flange, so as to cause ball valve and crystallizing tank
Between have in 20 ㎝ spacing, this 20 ㎝ spacing, bulk drug can not be stirred, after crystallization easily obstruction ball valve the problem of, the present invention
Purpose be the discharging device for disclosing a kind of crystallizing tank without spacing, without blind pipe.
The technical scheme that a kind of discharging device of the crystallizing tank of the present invention without spacing, without blind pipe is used is：It will crystallize at present
Tank drain hole is connected by flange → ball valve → flange, is changed to crystallizing tank drain hole and is directly connected to diaphragm valve.Due to using
Diaphragm valve, without flange, crystallizing tank drain hole, without spacing, without blind pipe, does not result in diaphragm valve obstruction with diaphragm valve.
Discharging device of a kind of crystallizing tank without spacing, without blind pipe, it is characterized in that by crystallizing tank, drain hole, diaphragm valve, blowing
Pipe is constituted.Crystallizing tank is provided with drain hole；Drain hole is connected with diaphragm valve；Vomit pipe is connected with diaphragm valve.
After bulk drug crystallization in crystallizing tank, diaphragm valve is opened, bulk drug is discharged from vomit pipe.Due to using diaphragm valve,
Without flange, crystallizing tank drain hole, without spacing, without blind pipe, does not result in diaphragm valve obstruction with diaphragm valve.
A kind of beneficial effect of discharging device of the crystallizing tank of the present invention without spacing, without blind pipe is：Device installs easy, operation
It is convenient；Crystallizing tank drain hole, without spacing, without blind pipe, does not result in diaphragm valve obstruction with diaphragm valve.
Brief description of the drawings
Fig. 1 is a kind of structural representation of discharging device of the crystallizing tank of invention without spacing, without blind pipe.
In figure, 1, crystallizing tank；2nd, drain hole；3rd, diaphragm valve；4th, vomit pipe.
Fig. 2 is the crystallizing tank drain hole structural representation before improving.
In figure, 1, crystallizing tank；2nd, drain hole；4th, vomit pipe；5th, flange；6th, ball valve.
Embodiment
A kind of discharging device of crystallizing tank without spacing, without blind pipe, it is characterized in that by crystallizing tank 1, drain hole 2, diaphragm valve 3,
Vomit pipe 4 is constituted.Crystallizing tank 1 is provided with drain hole 2；Drain hole 2 is connected with diaphragm valve 3；Vomit pipe 4 is connected with diaphragm valve 3.
After bulk drug crystallization in crystallizing tank 1, diaphragm valve 3 is opened, bulk drug is discharged from vomit pipe 4.Due to using barrier film
Valve 3, without flange, crystallizing tank drain hole 2, without spacing, without blind pipe, does not result in diaphragm valve 3 and blocked with diaphragm valve 3.
