The case where varying with temperature to cause to filter greatly and carry out slowly, or even can not carrying out.In addition, when filtering saturated solution, dissolution and mistake
It filters in the biggish situation of temperature change, solute is easy to be precipitated, and stops so as to cause filtering.In addition, melting temperature is higher than room temperature
Substance also often will appear solidification and lead to not filter, and if ferrous sulfate solution filters, remove solid impurity in phase-change material
When, often occur solidifying and filtering being caused to fail.
Utility model content
The purpose of the utility model is to provide a kind of laboratory filter devices, and filtering can be made to go on smoothly.
According to the utility model, a kind of use for laboratory temperature filtration device is provided, comprising:
There is receiving bottle top opening and side wall to aspirate pore；
Funnel has conical upper hopper portion and lower straight fistulae, and wherein upper hopper portion is formed with receiving port, lower straight fistulae
It is formed with discharge outlet；
Seal nipple is nested on the lower straight fistulae of funnel and in the top opening for being placed in receiving bottle, so that receiving bottle
Sealed fluid communication is formed between funnel；
Constant temperature jacket, shape are set in consistent manner on the outside of funnel, coat funnel upper hopper portion and lower straight fistulae it is upper
Portion, and extend beyond the upper hopper portion of funnel vertically upwards, constant temperature jacket has lower part water inlet pipe mouth and top effluent pipe mouth,
The position of middle and lower part water inlet pipe mouth corresponds to the upper hopper portion of funnel, and the position of top effluent pipe mouth is higher than the upper hopper of funnel
Portion；And
Sand core filter plate is completely covered the receiving port of funnel and is located within constant temperature jacket.
According to the utility model, the side wall suction pore of receiving bottle is preferably placed at the bottom of receiving bottle and the lower straight leakage of funnel
Between the lower end of pipe.
Filter device according to the present utility model can also include connecting (or connection) with the side wall of receiving bottle suction pore
Vaccum-pumping equipment.
Filter device according to the present utility model, can also include respectively with the lower part water inlet pipe mouth of constant temperature jacket and top
The constant temperature water circulating apparatus of effluent pipe mouth connection.
The utility model is compact-sized, easy to assembly, is formed by thermostatic control and sets with vacuum filtration function integration
Meter can greatly simplify operating process, reduces energy consumption and improve filter effect, be particularly suitable for the more special reality of temperature requirement
Test the filtering of operation such as ferrous sulfate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of temperature filtration device according to the present utility model.
Specific embodiment
The temperature filtration device of the utility model is further described in detail with reference to the accompanying drawing, but itself and do not have to
In limitation the utility model.
Fig. 1 diagrammatically illustrates the use for laboratory temperature filtration device of the utility model, generally includes receiving bottle 1, leakage
Bucket 2 and constant temperature jacket 3.
Receiving bottle 1 (being illustrated as triangular flask form) is formed with top opening or bottleneck, receives filtrate by it.In addition, connecing
The side wall for receiving bottle 1 is also formed with suction pore 10, for connecting vaccum-pumping equipment (not specifically illustrated) to be formed in receiving bottle 1
Negative pressure of vacuum.
Funnel 2 has the integrally formed and conical upper hopper portion being in fluid communication with each other and lower straight fistulae 20.Upper hopper
Portion forms receiving port, and lower straight fistulae 20 then forms filtrate discharge mouth.
As shown, seal nipple 4 is nested on lower straight fistulae 20, it is sealingly mounted in the top opening of receiving bottle 1, makes
Sealed fluid communication is formed between receiving bottle 1 and funnel 2.Seal nipple 4 can be formed to have the rubber stopper of intermediate throughholes.
Straight fistulae 20 wants moderate by the length that seal nipple 4 protrudes into receiving bottle 1 down, so that the suction tube formed on 1 side wall of receiving bottle
Hole 10 is located between the bottom of receiving bottle 1 and the lower end of lower straight fistulae 20, and can avoid filtrate logical during filter operation
Suction pore 10 is crossed to be sucked out.
3 shape of constant temperature jacket is set in 2 outside of funnel, the upper hopper portion of cladding funnel 2 and lower straight fistulae 20 in consistent manner
Top (part for exposing to receiving bottle 1), and the upper hopper portion of funnel 2 is extended beyond vertically upwards, after accommodating
Sand core filter plate 5 that face refers to simultaneously extends heating distance.Constant temperature jacket 3 has lower part water inlet pipe mouth 31 and top effluent pipe mouth 32.
The position of lower part water inlet pipe mouth 31 corresponds to the upper hopper portion of funnel 2, and the position of top effluent pipe mouth 32 is then higher than the upper of funnel 2
Pars infundibularis.Lower part water inlet pipe mouth 31 and top effluent pipe mouth 32 are respectively used to connection constant temperature water circulating apparatus (not specifically illustrated).
As shown, sand core filter plate 5 is arranged at the top edge in the upper hopper portion of funnel 2, it is located within constant temperature jacket 3
And the receiving port of funnel 2 is completely covered, to realize that solid-liquid efficiently separates herein during filter operation.
Receiving bottle 1 and funnel 2 can be made of glass；Constant temperature jacket 3 can then be made in order to observe of double glazing.
Below for filtering ferrous sulfate mixed liquor, the working principle of the utility model is briefly explained.
Before filtering starts, it is passed through the thermostatic medium water from constant temperature water circulating apparatus through lower water inlet 31, makes constant temperature
Medium water constantly from bottom to up heats funnel 2 in constant temperature jacket 3, and finally flows out from top water outlet 32, makes funnel 2
Entirety reaches target temperature.When starting filtering, ferrous sulfate mixed liquor to be filtered is first poured into the leakage in constant temperature jacket 3
In bucket 2, natural filtration to filtrate is almost no longer dripped；It is then turned on vaccum-pumping equipment to start to filter, solution is that sulfuric acid is sub- at this time
The mixing liquid of iron and ammonium sulfate；Then it is evacuated to and stops filtering when no filtrate is dripped.It takes out crystal to be placed on surface plate, observation produces
Product color, shape, weighing calculate theoretical productivity and yield.
