Description
Technical field
The utility model relates to the separating and filtering device field, is specifically related to a kind of electric heating constant temperature filter.
Background technology
In the separation of material, mensuration process; usually use filter method; wherein heat filtering is exactly a kind of common solid-liquid separating method; as need to filter while hot the purpose that reaches purifying when using the recrystallization method purifying substance; need carry out heat filtering during alcohol-insoluble substance in measuring cosmetics or articles for washing, the dissolved matter that will be dissolved in hot ethanol filters out.Therefore in daily separating substances or mensuration process, often use the heat filtering method.Heat filtering is most at present adopts a kind of heat filtering funnel to carry out, this heat filtering funnel uses the water in the alcolhol burner heated funnel usually, allow hot water keep temperature on the funnel, realize the purpose of heat filtering, because this method has adopted naked light (alcolhol burner) to heat, be not suitable for filtering and contain the flammable organic solvent of low boiling, otherwise cause easily and catch fire, produce fire.Use water in the alcolhol burner heat hot filter tunnel to realize the method for heat filtering in addition, temperature keeps constant when being difficult to guarantee to filter, and causing has many crystallizations or separate out solid matter in the funnel, influence filter quality.In addition, because the temperature of water is difficult to surpass 100 ℃ of high temperature, this method is not suitable for high temperature filtration, especially surpasses the separation of 100 ℃ heat filtering.Therefore, address the above problem, the separation of heat filtering need a kind ofly need not naked light heating, energy constant-temperature temperature-control, and is suitable for the higher heat filter of temperature, does not see the report of this quasi-instrument at present.
The utility model content
At the problems referred to above, the purpose of this utility model is to provide a kind of electric heating constant temperature filter, need not naked light heating, energy constant-temperature temperature-control, and is suitable for containing flammable organic solvent of low boiling or the higher heat filtering material of temperature, convenient and simple for operation, effective.
For achieving the above object, the utility model adopts following technical scheme:
The electric heating constant temperature filter is cylinder, and top is temperature filtration device 1, and the bottom is a heater 2, and is connected with temp sensing controller.
Above-mentioned temperature filtration device 1 comprises filter tunnel groove 11, intake-outlet 12, water level observation tube 13, with steam (vapor) outlet 14, filter funnel trough 11 is in recess on the cylinder surface, be funnel shaped, bottom straight flow heater 2, and run through cylindrical bottom, just put next common funnel, so that filter, intake-outlet 12 is in position, cylindrical middle and lower part, have switch, conveniently intake and water outlet, and design on the position of same plate face, be convenient to observe the water level of electric heating constant temperature filter with water level observation tube 13, water level observation tube 13 is in intake-outlet 12 tops, be transparent glass tube, and have scale that steam (vapor) outlet 14 is a cylinder, be on the cylinder surface, communicate in lower end and the temperature filtration device 1, the upper end communicates with air, can keep the normal pressure in the temperature filtration device 1.
Above-mentioned heater 2, heating tube is equipped with in the bottom, and be connected with temp sensing controller, the temperature that can control and regulate whole electric heating constant temperature filter by switch on the control panel 22 and temperature button 23, also has a support 21 in the lower end of heater 2, so that be fixed on the iron stand when using the electric heating constant temperature filter to filter, make things convenient for filter operation.
Compared with prior art, the present invention has following beneficial effect:
The utility model provides a kind of electric heating constant temperature filter, need not naked light heating, energy constant-temperature temperature-control, is suitable for the higher heat filtering of temperature.The utility model is simple to operate, result of use good, and cost of manufacture is low, and wide application is easy to popularize.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Structural representation of the present utility model as shown in Figure 1, the electric heating constant temperature filter is a cylinder, top is temperature filtration device 1, the bottom is a heater 2.Temperature filtration device 1 comprises filter tunnel groove 11, intake-outlet 12, water level observation tube 13, with steam (vapor) outlet 14, filter funnel trough 11 is in recess on the cylinder surface, be funnel shaped, bottom straight flow heater 2, and run through cylindrical bottom, just put next common funnel, so that filter, intake-outlet 12 is in position, cylindrical middle and lower part, have switch, conveniently intake and water outlet, and design on the position of same plate face, be convenient to observe the water level of electric heating constant temperature filter with water level observation tube 13, water level observation tube 13 is in intake-outlet 12 tops, be transparent glass tube, and have scale that steam (vapor) outlet 14 is a cylinder, be on the cylinder surface, communicate in lower end and the temperature filtration device 1, the upper end communicates with air, can keep the normal pressure in the temperature filtration device 1.Heater 2, heating tube is equipped with in the bottom, and be connected with temp sensing controller, the temperature that can control and regulate whole electric heating constant temperature filter by switch on the control panel 22 and temperature button 23, also has a support 21 in the lower end of heater 2, so that be fixed on the iron stand when using the electric heating constant temperature filter to filter, make things convenient for filter operation.
Method of operating: during use, the electric heating constant temperature filter is fixed on the iron stand by support 21, by intake-outlet 12 water is fed temperature filtration device 1 then, observe water level observation tube 13, until reaching certain water level, stop water flowing, the funnel and the filter paper that filter usefulness are put on the funnel trough 11, open the switch 22 of heater 2, and regulate the temperature of temperature button 23, heat to heat filtering, when temperature reaches the temperature of setting, can filter, finish, turn off the switch 22 and the temperature button 23 of heater 2 until filtration.
