Abstract
The utility model relates to a hot filtering hopper for a laboratory, which can effectively solve the problems in the prior art that the liquid heating effect is poor and the filtering speed is low. According to the technical scheme, the hot filtering hopper for the laboratory comprises a laminated glass hopper body and a laminated glass hopper neck, the laminated glass hopper inner wall and the laminated glass hopper outer wall are closed to form an empty cavity, an air inlet pipe and an air outlet pipe are both positioned at the upper part of the laminated glass hopper outer wall, the air inlet pipe extends in the empty cavity to be connected with the upper end of an air guide pipe arranged in the empty cavity, the lower end of the air guide pipe is arranged on the bottom of the laminated glass hopper neck, a horizontal glass screen which is integrated together with the laminated glass hopper inner wall is arranged above a horn-shaped lower outlet on the laminated glass hopper inner wall, and cup-shaped filter paper is arranged on the glass screen. The hot filtering hopper for the laboratory is good in heat preservation function, capable of preventing solvent evaporation, low in cost, and easy to operate, and is an innovation of hot filtering experiment utensils.
Description
Technical field
The utility model relates to experimental facilities, particularly a kind of laboratory heat filtering funnel.
Background technology
In scientific research and teaching Process of experiment, the heat filtering experiment is one of main method of purifying solid chemical compound, also is one of main experimental implementation content of laboratory student experimenting and scientific research activity.At present, the laboratory student mainly contains with the heat filtering device: (1) metal chuck heat filtering funnel, formed by single-glass funnel and metal (copper) chuck, be by the water in the alcolhol burner heating of metal chuck, and then solution improves the heat filtering temperature in the indirect funnel, its temperature is uncontrollable, the heating liquid weak effect, the filtrate obstruction filler neck that very easily condenses, cause the rate of filtration slow, and exist the naked light of metal chuck cost height, alcolhol burner that there is security hidden trouble in inflammable and explosive solvent.(2) hot suction filtration device adopts the mode of Buchner funnel heating, is earlier Buchner funnel to be placed in the baking oven to heat before heat filtering, and this mode temperature retention time is short, and volatile solvent is caused easily the quick crystallization of filtrate causes purification effect poor in bottle,suction.
Therefore, it is constant to develop a kind of fluid temperature that can keep in the funnel, the heat filtering experimental provision that filtrate being difficult for solidifies, raising conventional efficient, guarantee product yield, experimental provision cheap, easy to use, that satisfy heat filtering experiment demand are the technical problems that needs to be resolved hurrily.
Summary of the invention
At above-mentioned situation, for solving the defective of prior art, the purpose of the utility model just provides a kind of laboratory Rapid Thermal filter tunnel, can effectively solve prior art heating liquid weak effect, filtrate very easily condense stop up filler neck cause the rate of filtration slowly, the suction filtration mode that adopts the preheating Buchner funnel easily causes solvent evaporates to cause the quick crystallization of filtrate and influences the problem of purification effect.
The technical scheme that the utility model solves is, comprise laminated glass infundibular body and laminated glass filler neck, the closed formation of laminated glass funnel inwall and laminated glass funnel outer wall cavity, inlet tube and gas outlet Guan Jun are positioned at the top of laminated glass funnel outer wall, inlet tube stretches into and connects the wireway upper end that places in the cavity in the cavity, the wireway lower end places above the bottom of laminated glass filler neck, there is the horizontal glass web that merges with laminated glass funnel inwall the outlet top under the laminated glass funnel inwall loudspeaker, is placed with cup-shaped filter paper above the glass web.
The utility model heat insulation function is good, the prevention solvent evaporates, and cost is low, and is easy to operate, is the innovation on the heat filtering experimental ware.
Description of drawings
Fig. 1 is structural perspective of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
Provided by Fig. 1, the utility model comprises laminated glass infundibular body 1 and laminated glass filler neck 2, laminated glass funnel inwall 3 and laminated glass funnel outer wall 5 closed formation cavitys 4, inlet tube 6 and gas outlet pipe 7 all are positioned at the top of laminated glass funnel outer wall 5, inlet tube 6 stretches into and connects wireway 8 upper ends that place in the cavity in the cavity 4, wireway 8 lower ends place above the bottom 9 of laminated glass filler neck 2, there is the horizontal glass web 10 that merges with laminated glass funnel inwall 3 the outlet top under laminated glass funnel inwall 3 loudspeaker, is placed with cup-shaped filter paper 11 above the glass web 10.
In order to guarantee result of use, described cup-shaped filter paper 11 suitable for reading is lower than the suitable for reading of glass funnel body 1.
Between described cup-shaped filter paper 11 and the laminated glass funnel inwall 3 space is arranged.
The bottom 9 of described laminated glass filler neck 2 takes the form of inclined plane, and there is the central through hole 12 that is communicated with outlet under laminated glass funnel inwall 3 loudspeaker at the center.
Described wireway 8 lower ends place 2～3mm place above the bottom 9.
During heat filtering, water vapour imports the cavity of laminated glass funnel by inlet tube, and very fast funnel will be by constant temperature to higher temperature, has avoided the filtrate obstruction filler neck that condenses.
The utlity model has following outstanding advantage:
1. the utility model has solved the problem that constant temperature weak effect, filtered fluid condense the obstruction filler neck easily.
2. structure of the present utility model is the laminated glass funnel, has avoided the use metal sandwich, has reduced experimental cost.
3. avoided the alcolhol burner heating to have the problem of potential safety hazard.
4. the crystal of separating out that the solvent evaporates of having avoided suction filtration to cause causes causes the impure problem of product soon.
The utility model has improved insulation and filter effect, has guaranteed the accuracy of experimental data; Reduced experimental cost; The potential safety hazard of having avoided the naked light heating to exist, and simple, convenient, be the heat filtering experimental ware that effectiveness is arranged in scientific research and the chemical experiment, have good economic and social benefit.
