Background technology
At present, the common filter method of chemical laboratory is carried out by means of Buchner funnel and glass funnel, it is difficult to do
To filter at low temperature (less than 0 DEG C), simple glass funnel is very slow by the gravity rate of filtration when room temperature filters, and Buchner funnel
Though decompression pumping can improve the rate of filtration, when high temperature filtration, needs to put Buchner funnel pre- in preheating in an oven or hot water
Heat, operation is time-consuming and laborious, and it is very inconvenient to take dismantling device, first, vessel are very boiling hot, difficult, fragile vessel, second is that by day during taking-up
Gas influences greatly, and when wintry weather is colder, when the solubility with temperature of substance particularly to be crystallized is changed greatly, partially crystallizable can leak
It is precipitated in bucket, product loss is big, low yield.
Invention content
The technical problems to be solved by the invention are to overcome above-mentioned the deficiencies in the prior art, provide a kind of reasonable design,
Structurally simple, economical environmentally friendly, of low cost, easy to operate, product loses much lower purposes filter.
Solve above-mentioned technical problem the technical solution adopted is that：The outer wall of filter body is provided with handle, filter sheet
The center of body is connected as a single entity with filter body and is provided with funnel, and the liquid storage of closing is formed between funnel and filter body
Slot, what filter body top was connected with reservoir is provided with inlet tube and exhaust pipe, and feed liquor lid is provided in air inlet pipe, is arranged
Exhaust cap is provided on tracheae.
The filter body of the present invention is set as hollow structure, and filter hollow space is provided with insulating layer.
The filter body of the present invention is cylindrical or regular polygon structure.
The funnel of the present invention is Buchner funnel.
The plug being adapted with the bottleneck diameter of bottle,suction is provided on the lower end filler neck of the filter body of the present invention.
The funnel of the present invention is simple glass funnel.
Plug is provided on the lower end filler neck of the filter body of the present invention.
The filter body of the present invention is made of polytetrafluoroethylene (PTFE).
Injection high temperature paraffin oil, boiling water or hypothermic saline on the rocks in the reservoir of the present invention.
The present invention has the following advantages compared with the prior art：
1st, filter body is made of polytetrafluoroethylene (PTFE), of low cost, easily molded, and heat dissipation and heat absorption are slow, in hot mistake
It is influenced when filter or cold filtering by ambient temperature smaller.
2nd, filter body is processed into hollow structure, inside filling thermal insulation material, and when high temperature filtration prevents heat from distributing, and subtracts
Few internal thermal loss, when filter at low temperature, reduce extraneous heat transfer.
3rd, filter body and funnel design are structure as a whole, and reservoir is formed between filter body and funnel, can be added
Enter paraffin oil, boiling water or hypothermic saline on the rocks, meet the requirement of heat filtering and cold filtering, several students are reusable, carry
High utilization rate of equipment and installations.
4th, it is provided with handle outside filter body so that student's operation is easy, while thermal insulation material prevents well
Heat is transmitted, and prevents from scalding in student's operating process, filter process more handy and safe.

Specific embodiment
The present invention is described in further details with reference to the accompanying drawings and examples, but the present invention is not restricted to these implement
Example.
Embodiment 1
In Fig. 1,2, the present embodiment versatile filter, filter body 2 be cylindrical structure, filter body 2 by
Polytetrafluoroethylene (PTFE) is made, and polytetrafluoroethylene (PTFE) is of low cost, easily molded, and heat insulation effect is good, can effectively prevent heat transfer, filtering
Device ontology 2 is designed as hollow structure, and 2 hollow space of filter body is set as the insulating layer filled with thermal insulation material, both can be with
Internal heat is prevented to distribute in heat filtering, reduce thermal loss, and outside heat can be prevented to transmit in cold filtering, avoided
Therefore cold filtering failure is caused, the outer wall of filter body 2 is machined with handle 1, and handle 1 facilitates student to be grasped in filtration experiment
Make, center and the filter body 2 of filter body 2, which are connected as a single entity, is provided with funnel 4, and the funnel 4 of the present embodiment is cloth
Family name's funnel 4-1, Buchner funnel 4-1 decompression pumping can improve the rate of filtration, the lower end Buchner funnel 4-1 necks of filter body 2
It is provided with the plug 6 being adapted with the bottleneck diameter of bottle,suction.
The reservoir of closing is formed between funnel 4 and filter body 2, high temperature paraffin oil or boiling can be added in reservoir
Water to meet the requirement of heat filtering, adds in hypothermic saline on the rocks during cold filtering, to meet the requirement of cold filtering, mistake in reservoir
