Abstract
The utility model relates to a constant-temperature sand core funnel, in particular to a sand core funnel with a constant-temperature interlayer, which can realize constant temperature or be heated, and is used in a laboratory. The sand core funnel comprises a funnel main body and the constant-temperature interlayer; the constant-temperature interlayer is arranged on the tube outer wall of the funnel main body; a circulating water inlet is formed in the lower part of the constant-temperature interlayer; a circulating water outlet is formed in the upper part of the constant-temperature interlayer. The sand core funnel can be connected with a self-provided circulating pump of constant-temperature equipment through a hose; circulating hot water with a certain temperature is placed in the interlayer to realize the constant temperature of the sand core funnel so as to effectively avoid solidifying of a solvent or a partial crystallization phenomenon, which is caused by the reduction of the temperature, thereby ensuring a suction filtration effect. The sand core funnel provided by the utility model has the advantages of simple structure, practicality, convenience in operation and use, and the like.
Description
Technical field
The utility model relates to a kind of constant temperature sand core funnel, and what particularly relate to a kind of use for laboratory band constant temperature interlayer can constant temperature or the sand core funnel of heating.
Background technology
At chemical products, often to need to use sand core funnel, sand core funnel be that acid-resistant glass filters instrument for refining or recrystallization, can filter acid solution and process with acids.Because traditional sand core funnel can not be heated or constant temperature; chemical reagent for easy crystallization under the high or low temperature of some freezing points; as glacial acetic acid etc. when the decompress filter because temperature is lower; often can become solid or occur that part is icing; affect suction filtration effect; cause experiment effect poor, sometimes even make the failure of an experiment.Prior art is in suction filtration process, to adopt hot blast to heat, to improve temperature to heat or with hot towel, operates very inconvenient.Therefore, be necessary to develop in fact a kind of sand core funnel that can effectively control temperature.
Utility model content
The purpose of this utility model is to provide a kind of use for laboratory constant temperature sand core funnel.Solution is in product purification or product recrystallization process, and the suction filtration solvent of the lower appearance of Yin Wendu easily becomes solid or occurs the phenomenons such as partially crystallizable, has improved suction filtration effect, has guaranteed experiment effect.A kind of use for laboratory constant temperature sand core funnel that the utility model provides, has guaranteed suction filtration efficiency, simple in structure, practical, easy for operation.
For addressing the above problem, the utility model provides a kind of use for laboratory constant temperature sand core funnel.
Constant temperature sand core funnel of the present utility model is comprised of funnel body and constant temperature interlayer, the pipe outer wall of described funnel body is provided with constant temperature interlayer, described constant temperature interlayer bottom is provided with recirculated water entrance, top is provided with circulating water outlet, and the circulating pump that this recirculated water entrance and circulating water outlet carry with thermostatic equipment is connected.The circulating hot water that passes into uniform temperature in constant temperature interlayer carries out constant temperature to sand core funnel, can effectively avoid Yin Wendu to reduce the generation that the solvent causing easily becomes solid or occurs partially crystallizable phenomenon, has guaranteed suction filtration effect, improves experiment effect.
Preferably, the circulating pump that described recirculated water entrance and circulating water outlet carry with thermostatic equipment by flexible pipe is connected.Adopt flexible pipe to connect placement and the operation that can facilitate equipment.
Preferably, described flexible pipe can be selected rubber or plastic or other material, adopts the flexible pipe of this material, under laboratory condition, can conveniently use the flow of the flexible controlled circulation water of the parts such as clip, rubber or plastic material can be heat-resisting enduringly simultaneously, can guarantee the safety of experiment, stable.
A kind of constant temperature sand core funnel that the utility model provides, the advantage such as simple and practical, easy for operation.
The use for laboratory constant temperature sand core funnel that the utility model provides, by pass into the circulating hot water of uniform temperature in interlayer, sand core funnel is carried out to constant temperature, can effectively avoid Yin Wendu to reduce the generation that the solvent causing becomes solid or occurs partially crystallizable phenomenon, guarantee suction filtration effect.A kind of constant temperature sand core funnel that the utility model provides, the advantage such as simple and practical, easy for operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 funnel body; 2 constant temperature interlayers; 3 recirculated water entrances; 4 circulating water outlets.
The specific embodiment
Below coordinate accompanying drawing and preferred embodiment of the present utility model, further setting forth the utility model is to reach the technological means that predetermined utility model object is taked.
As shown in Figure 1, the utility model is comprised of funnel body 1 and constant temperature interlayer 2, on the pipe outer wall of funnel body 1, is provided with constant temperature interlayer 2, and constant temperature interlayer 2 bottoms have recirculated water entrance 3, and top has circulating water outlet 4.Recirculated water entrance 3 is connected with the circulating pump that circulating water outlet 4 can carry with thermostatic equipment by flexible pipe.
When experimental implementation, the utility model and bottle,suction, air extractor are connected.Before carrying out suction filtration operation, recirculated water entrance 3 of the present utility model is connected with the circulating pump that circulating water outlet 4 carries with thermostatic equipment by flexible pipe, by circulating hot water, make after the suction filtration material constant temperature in funnel body 1, can start suction filtration operation.
The above is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model, any those skilled in the art, within not departing from the scope of technical solutions of the utility model, should utilize the technology contents of above-mentioned announcement to make a little change or be modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solutions of the utility model, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
