Embodiment
It is further detailed to the embodiment work of the present invention by the description to embodiment below against each accompanying drawing
Explanation, to help inventive concept of the those skilled in the art to the present invention, that technical scheme has is more complete, accurate and deep
Understand.Numeral after technical characteristic is consistent with the mark in accompanying drawing, is easy to compare.
Taken out as shown in Figure 1, Figure 2 with the structure of the invention expressed by Fig. 3, the present invention for a kind of heat applied to Scientific Research in University Laboratory
Filter device.Silica gel is used at the present apparatus two, the advantages of silica gel：With excellent heat resistance, resistance to weathering and higher machine
Tool intensity, nonpoisonous and tasteless corrosion-free, not soluble in water and any solvent, stable chemical performance.Because the thermal conductivity of copper is good and price
Cheaply, water leg uses copper material.
As depicted in figs. 1 and 2, upper lid (11) is screwed up tightly with the bottleneck of receiving flask 4 by screw thread.It will will be quantified with long neck funnel
Hot water the 2/3 of water leg capacity (be no more than) be added to by bursting tube (9) in water leg (6), the line that plugs in (14) is opened
Begin to heat,.Buchner funnel is put and taken in Buchner funnel device (2) insertion water leg, it is closely connected with silica gel ring 8.In order to
Make heat-transfer effect more preferable, micro hot water (can also be not added with) can be added between water leg and Buchner funnel.By conduit mouth
Connect vavuum pump.After jacket temperature is increased to certain temperature, filter paper is put into Buchner funnel, vavuum pump is opened, pours into
Heat filtering solution is treated, the filtering of moment solution is completed.Lid (11) and receiving flask (4) bottle connection are outwarded winding, it is dry to screw on another
Net mother liquor receiving flask (4), next group of classmate start heat filtering, and this group of classmate pours out mother liquor, scraper when having crystal precipitation
Crystal is scraped, then receiving flask (4) wash clean is stand-by, such rotation uses.
As shown in figure (4), if due to heat filtering mother liquor, should not filter cake, can not have to often on replacing Buchner funnel
Filter paper, when filter cake is more influences heat filtering speed, the handle (17) for taking Buchner funnel device can be caught upwards firmly to leak Bu Shi
Bucket takes out from water leg, and gear mouth (18) down, tilts Buchner funnel, removes filter paper and filter cake, with hot water injection's Buchner funnel,
Buchner funnel is put back in water leg again, continues hot suction filtration.
The present apparatus actual use when, due to water leg use it is long, inside can scaling, will not be surpassed by long neck funnel
The diluted acid for crossing water leg capacity 2/3 is added in chuck, rotates chuck, after using acid, incrustation scale is dissolved, then is poured out by bursting tube,
Cleaned twice with clear water again.
The present apparatus can also add silicone oil in water leg, higher temperature can be given, for one in actual use
The heat filtering of a little high boiling solvents.
The present apparatus can connect transformer and temperature controller, for controlling water leg in actual use at power line
Temperature.
For those skilled in the art, technical scheme that can be as described above and design, it is various to make other
It is corresponding to change and deform, and all these change and deformation should belong within the protection domain of application claims.
