Description
Technical field
The utility model relates to the filtering device systems that a kind of universal filter more particularly to biological organic chemical industry are tested.
Background technique
Filtering or to filter be the common chemical industry operation unit in laboratory or even chemical plant, commonly used in liquid is solid or gas-solid mixing
Fluid in object is forced through porous filter medium, and suspended solid particles therein is retained, to realize mixture
Separation.
There are several types of 1. cloth funnels, quantitative filter paper, suction filtration for traditional experiment room common filtering complete equipment mode
Bottle, vacuum pump, rubber tube and plug；2. sand core funnel, bottle,suction, vacuum pump rubber tube and plug；3. glass funnel, quantitative filter
Paper or filter membrane, iron shelf, bottle,suction, vacuum pump, rubber tube and plug；4. other such as non-woven fabrics funnel, stainless steel iron net funnel
Deng.Since these common filter types have general character and individual character, such as (1) filter pressure is not high, vacuum pump limiting pressure
- 0.1Mpa can only be approached, higher external forces filter is unable to satisfy；(2) filtering environment be usually room temperature, in this environment certain solution or
Solute may solidify or gasify, and filtering versatility is not strong, and (3) filtering accuracy efficiency is relatively low, and the aperture of ordinary filter paper is quickly
80 ~ 120 μm, middling speed be 30 ~ 50 μm, be at a slow speed 1 ~ 3 μm, filtering accuracy is relatively low；0.6 ~ 30 μm of sand mold funnel, easy plug-hole and displacement
Difficulty reuses low efficiency.Therefore, that there are systems is not withstand pressure for conventional filtration aggregates, and leakproofness is not good enough, filtering accuracy and efficiency
It is relatively low, it is difficult to complete at room temperature simultaneously for such as 50-90 DEG C of melting range of the filtering of certain substance, simultaneously for certain class object
Matter appearance turbidity or index of refraction require high solvent, and conventional aperture precision is difficult to realize.
CN204767672U describes the positive press filtration device with agitating device, only with stirring and positive pressure common mode mistake
Filter, filtering use scope is narrow, does not have experiment versatility；A kind of multi-joint vacuum filter of CN206214860U, have and in conjunction with
When filtering function, but its deficiency is can only depressurize room temperature filtering, and leakproofness is not good enough, i.e. filtering accuracy effect is bad.
For deficiency and defect existing for the above Routine Test Lab filter plant facility, the utility model patent proposes one kind
By filter, it can make up and effectively solve problem above, it is wide to reach filter pressure range, and filtering environment temperature is wide, filtering
The number of advantages such as precision is high-efficient and is sealed.

The cylinder body outer wall is provided with collet, and collet lower part is provided with medium entrance；Cylinder top is provided with medium and goes out
Mouthful；Cylinder lateral wall is disposed with pressure gauge, medium temperature table, thermometer from top to bottom.
The cylinder is one or more；When being multiple, the isolating valve between cylinder through being arranged on the support frame of bottom connects
It connects.
Compared with prior art, the utility model have it is following the utility model has the advantages that
(1) it filters or suction filtration pressure is higher.It is conventional to be become using water ring vacuum pump or sliding vane rotary vacuum pump its negative pressure limit
Closely -0.1Mpa, and the compatible positive pressure of this filter and negative pressure filtration function, wherein positive pressure is designed up to 0.5Mpa, crucial filter membrane
It handles, intensity and resistance to can meet the requirements admittedly and upper top cover cover and web plate flange are by increasing by special upset, support
Sealing ring and screw rod reinforcement by connection match safety attachment pressure gauge and safety valve.
(2) it filters or suction filtration precision is higher.General measure filter paper aperture is quickly 80 ~ 120 μm, middling speed is 30 ~ 50 μm, slowly
Speed is 1 ~ 3 μm, integral filter accuracy error, and 0.6 ~ 30 μm of sand mold funnel, easy plug-hole and displacement is difficult reuses low efficiency.
And the design of this filter supports two-sided web plate, face-flange, groove, sealing ring (oil resistant, acid and alkali-resistance, heatproof), filter membrane is using more
Kind of material (PP, PE, PTFE, PVDF etc.), same Heat-stable oil resistant, 0.20 ~ 50 μm of filter membrane precision, filter membrane replacing facilitate through
Ji.
(3) it filters or suction filtration temperature is wider.Routine Test Lab Buchner funnel, glass funnel or sand shape funnel with extraneous ring
Border communicates, and the temperature of solution is consistent with the external world inside funnel, be unable to satisfy laboratory specific " filtering while hot ", " high temperature filtration ",
Harsh conditions such as " filter at low temperature ", and this circular cylinder body is that stainless steel has collet, collet medium sources are in -15 ~ 95 DEG C of perseverances
Warm device may be implemented constant heat preservation filtering, meet the requirement of substance physical property, while liner cylinder is resistant to soda acid.
