Description
Technical field
The present invention relates to a kind of residual extraction liquid processing device of medicine, and in particular to locates before a kind of high flux for the residual extraction of medicine
Manage instrument.
Background technology
As the improvement of people's living standards, while aquatic products production and consumption yield is greatly improved, aquatic products
Quality problems also increasingly attract attention；The quality good or not of aquatic products how is examined, is the problem of consumer pays special attention to.According to
The alimentary codex of correlation, Food Inspection regulation require that aquatic products are needed by the side such as organoleptic examination, physical examination, chemical analysis
The detection in face is to ensure the quality safety of aquatic products.
At present, the extraction step of the sample extracting solution of aquatic products detection generally includes following steps：First will be to be detected
Aquatic products, which are smashed to pieces, to be put into sample cell, and adds in sample cell a certain amount of organic solvent；Then Syrup-homogenizing instrument or vortex are passed through
Oscillator is homogenized to the sample in sample cell, the left drug in aquatic products is dissolved into organic solvent；Followed by adopting
The residue filter in sample cell is obtained into sample extracting solution with the mode of centrifugation or filtering.The behaviour of current this sample extracting solution
Make that process is comparatively laborious, waste time and energy, and a sample cell can only once be operated, this causes big in actually detected
The sample of batch is often devoted a tremendous amount of time.
The content of the invention

Provided with the first guide pin bushing that can be slided along vertical connecting rod, and the first guide pin bushing is provided with can make the first guide pin bushing be fixed on vertical connecting rod
On tight fixed bolt；The turbula shaker is located at below mounting seat.This programme structure can carry out even to multiple samples simultaneously
Slurry operation, its is easy to operate, and operating efficiency is high.
Preferably, also including extracting liquid separating apparatus, liquid separating apparatus is taken to include vaccum-pumping equipment, with sealed internal chamber
Main box, be arranged on the circular placement through hole and communication type airtight construction on main box top surface；It is located in main box and places
Through hole is arranged right below some and one-to-one extract solution surge drum of knapsack；The communication type airtight construction includes being arranged on
Place the mounting groove on through hole medial surface, the inflation seal ring being arranged in mounting groove and pressure conversion cylinder body；The pressure
The inner chamber for changing cylinder body is made up of interconnected the first cavity and the second cavity, and the internal diameter of the first cavity is more than the second cavity
Internal diameter；It is provided with first piston body, the second cavity in first cavity and is provided with second piston body, and first piston body and the
It is connected between two piston bodies by head rod, close to the one end open of first piston body on the pressure conversion cylinder body,
Close to one end closing of second piston body；The first inside cavities face is provided with the first limited block, and the first limited block and the
Two piston bodies are located at first piston body opposite sides, and second cavity, which is provided with, can make first piston body be resisted against the first limited block
On the first pretension compression spring, and the first pretension compression spring and first piston body are located at second piston body opposite sides；Institute
Pressure conversion cylinder body lateral surface is stated provided with the first connector and the second connector, the first connector is connected with the first cavity,
And first connector be located between first piston body and second piston body；Second connector is connected with the second cavity, and second
Connector is located at second piston body opposite sides with first piston body；The main tank outside is provided with the 3rd connector and takes out

Make efficiency high.
On the other hand, in actual use, because mounting seat needs to be frequently inserted placement through hole/taking-up so that put
Put the sealing ring between through hole and mounting seat easily to loosen, produce gap, cause extraneous gas in main tank intracoelomic cavity vacuum
Body enters main tank intracoelomic cavity, influences the filtering of sample extracting solution；This programme is improved for this problem, is effectively solved because putting
The poor sealing between through hole and mounting seat is put, and causes the negative pressure for vacuumizing cavity not enough, influence sample extracting solution filtering
Problem.
Because the pressure conversion inner chamber of cylinder block between first piston body and second piston body passes through the first connecting pipe and master
The intracavity inter-connection of casing, and cross-sectional area of the cross-sectional area more than second piston body of first piston body；Thus taking out true

It is dynamic, so that the gas in pressure conversion cylinder body to be pressed into the interior intracavitary of inflation seal ring by the second connecting pipe, make inflation
Formula sealing ring expands, and then ensures that inflation seal ring forms reliable sealing between cartridge filter and placement through hole；And with
The air pressure for intracavitary in the negative pressure increase of main tank intracoelomic cavity, the annular inflatable of inflation seal ring also increases therewith, so as to enter one
Step ensures inflation seal ring in cartridge filter and places and form reliable sealing between through hole, effectively solve because cartridge filter need through
Often take out cleaning and dress sample so that place the sealing ring between through hole and cartridge filter and loosen, produce gap, and influence cartridge filter with
Place through hole between sealing reliability, and with main tank intracoelomic cavity negative pressure increase, tend to produce place through hole with
The problem of poor sealing between cartridge filter.On the other hand, after the completion of sample extracting solution filtering, vaccum-pumping equipment is closed, this
When main box chamber pressure recover so that first piston body and second piston body are multiple in the presence of the first pretension compression spring
Position, now inflation seal ring contraction, so that mounting seat is smoothly taken out, it is ensured that equipment normal work.
