Abstract
The utility model discloses a kind of online vacuum degasification instrument device, structure is：Frame and supporting plate are fixed with bottom plate, and the upper and lower side of front panel is fixed with frame and bottom plate respectively.Heater assembly is fixed on bottom plate.Diaphragm pump and degassing membrane component are separately fixed on supporting plate, and vacuum table and regulating valve concatenation, the exhaust outlet of degassing membrane component is in parallel with vacuum table and regulating valve pipeline to be followed by the bleeding point of instrument.It does not deaerate distilled water or deionized water enters diaphragm pump through diaphragm pump water inlet, then enter heater assembly through diaphragm pump water outlet, distilled water enters degassing membrane component water inlet pipe after being heated, and the degassed membrane module outlet pipe of de aerated water is exported to the degassing water outlet of instrument.On-line degassing is realized using " heating immediately and gas-liquid separation technology ", effectively reduces distillation treatment time of water.Since instrument internal is without water storage device, the volume of degassing instrument is made to be obviously reduced, ideal degasser is provided for pharmacy and chemical industry.
Description
Technical field
The utility model, which relates to, belongs to drug test instrument, and in particular to a kind of to be taken off online to distilled water or deionized water
The device of gas.
Technical background
China's States Pharmacopoeia specifications have hundreds of drugs to need to do Dissolution Rate Testing, and drug is in Dissolution Rate Testing, used
Solvent needs are de-gassed.In order to prepare the solvent of degassing, first have to using water to be de-gassed.But it is existing de-
Gas instrument be the water in fluid reservoir is heated, circulation stirring and vacuumizing is de-gassed, defect is degassing time
Length, working efficiency are low, and usually because fluid reservoir cleaning is not thorough long mould, and increase the labor intensity of maintenance personal.Separately
On the one hand, the volume of this degassing instrument is larger, and the space occupied is also big.Due to the presence of these problems, drug-eluting is caused to try
It is low to test efficiency.The it is proposed of the utility model will be such that the above problem is satisfactorily solved.
Invention content
The purpose of this utility model is to provide a kind of on-line degassing device, has solved above-mentioned deficiency.
The composition and technical pattern of the utility model be：Online vacuum degasification instrument has：Frame, bottom plate, supporting plate, front
Plate, heater assembly, diaphragm pump, degassing membrane component, vacuum table, regulating valve, negative pressure pump etc..Frame is fixed on bottom plate, holder
Plate upper end is fixed with frame；Lower end is fixed with bottom plate.Front panel is arranged on the top of frame, and heater assembly is fixed on front panel
On the bottom plate of lower section, diaphragm pump and degassing membrane component are separately fixed on supporting plate.Front panel is equipped with vacuum table and regulating valve, bears
Table and regulating valve concatenation are pressed, the exhaust outlet of degassing membrane component is in parallel with vacuum table and regulating valve pipeline to be followed by the pumping of instrument
Mouthful.Diaphragm pump lower end is equipped with water inlet；Diaphragm pump upper end water outlet is connected to the water inlet of heater assembly, the water of heater assembly
Outlet is connected to the water inlet pipe of degassing membrane component, and the outlet pipe of the degassed membrane module of de aerated water is exported to the degassing water outlet of instrument.
The bleeding point of instrument is connected to external negative pressure pump.
Diaphragm pump is sucked pending distilled water or deionized water by water inlet, by it when then flowing through heater assembly
It is heated to predetermined temperature, degassing membrane component is carried out gas-liquid separation under the action of negative pressure pump, then obtains degassing used
Water, de aerated water are entered by the water outlet on front panel in external volumetric flask or water tank.As long as having abundant water resources, so that it may
De aerated water is persistently provided.
The characteristics of the utility model and advantageous effect are：It is realized using " heating immediately and gas-liquid separation technology " online de-
Gas effectively reduces the time handled distilled water or deionized water, can almost be deaerated without waiting after booting
Water.It saves the working time and improves work efficiency.Since instrument internal is without water storage device, the volume of degassing instrument is made obviously to subtract
It is small, provide ideal degasser for pharmacy and chemical industry.
Description of the drawings
Fig. 1 is the system composition and structure chart of the utility model.
Specific implementation mode
It is described further below in conjunction with attached drawing and by specific embodiment to the principles of the present invention structure.
Online vacuum degasification instrument, structure composition are：Frame 1 is fixed on a base plate 2, and 3 upper end of supporting plate is fixed with frame；
Lower end is fixed with bottom plate.Front panel 4 is arranged on the top of frame, and heater assembly 5 is fixed on the bottom plate below front panel, every
Membrane pump 6 and degassing membrane component 7 are separately fixed on supporting plate.Front panel is equipped with vacuum table 8 and regulating valve 9, vacuum table and adjusting
Valve concatenates, and the exhaust outlet 7-1 of degassing membrane component is in parallel with vacuum table and regulating valve pipeline to be followed by the bleeding point 10 of instrument.Diaphragm
It pumps lower end and is equipped with water inlet 6-1；Diaphragm pump upper end water outlet 6-2 is connected to the water inlet of heater assembly, the water of heater assembly
Outlet is connected to the water inlet pipe 7-2 of degassing membrane component, and the outlet pipe 7-3 of the degassed membrane module of de aerated water exports to the degassing of instrument
The mouth of a river 11.The bleeding point of instrument is connected to external negative pressure pump gas circuit unit, is taken off to distilled water or deionized water to realize
Gas disposal.
In order to ensure degasifying effect, the operating temperature of distilled water or deionized water is detected in real time, in heater assembly
Equipped with temperature sensor.
The distilled water (or deionized water) that do not deaerate enters diaphragm pump through diaphragm pump water inlet, then through diaphragm pump water outlet into
Enter heater assembly, distilled water enters degassing membrane component water inlet pipe, the degassed membrane module outlet pipe output of de aerated water after being heated
To the degassing water outlet of instrument.
The course of work of the online vacuum degasification instrument of the utility model is：Power on switch, temperature and pressure parameter be set,
The start button on front panel (display screen) is pressed, the preparation of water is de-gassed.At this point, negative pressure pump and diaphragm pump work at the same time,
Pending distilled water or deionized water is inhaled into from the water inlet of diaphragm pump lower end, is flowed through diaphragm pump and is entered heater assembly
It is heated to predetermined temperature, while passing through degassing membrane component, gas-liquid separation is carried out under the action of negative pressure pump, the water to have deaerated
Continually from the liquid outlet of instrument, flow out in external volumetric flask or water tank.In de aerated water preparation process, if water
Source is insufficient or too low into flow velocity, instrument meeting alarm, and stopping prepares de aerated water, is ready to then continue behind water source
Prepare de aerated water.
