Abstract
Constant temperature dropping liquid feeder, relates to chemical engineering experiment instrument, is specially the constant temperature dropping liquid feeder that a kind of chemical experiment and enlarged experiment and suitability for industrialized production use.In the outside of feeder cylindrical shell with constant temperature overcoat, there is a constant temperature liquid outlet on the top of constant temperature overcoat side, have a constant temperature liquid import in constant temperature overcoat opposite side bottom.Feature of the present utility model increases constant temperature overcoat in the outside of common feeder cylindrical shell, and when needs high temperature, the import of constant temperature liquid connects high temperature circulation oil bath pan or water-bath by pipeline, then form the circulatory system by the outlet of constant temperature liquid with thermal source pot.For the heating of feeder cylindrical shell, under being in suitable temperature to keep experiment material.For the heating raw materials in dropping liquid feeder is to the temperature that is in a liquid state.Otherwise when needs low temperature, connect sub-cooled circulation pot or frozen water bath.With this feeder can high temperature be no more than 140 DEG C, low temperature be not less than subzero 15 DEG C scope in ensure that material is liquid condition under, long-time constant temperature carries out dropwise operation, and material can not lose, also without any danger.Solve existing equipment Problems existing.
Description
Technical field
The utility model relates to chemical engineering experiment instrument, is specially the constant temperature dropping liquid feeder that a kind of chemical experiment and enlarged experiment and suitability for industrialized production use.
Technical background
In chemical experiment, a lot of experiment material needs to drip mode, joins reaction system and carries out chemical reaction.But, have some experiment materials at room temperature, in crystal or solid; Or because boiling point is lower than room temperature, and vaporization or volatile, cause experiment cannot operate or measure inaccurate, even produce pressure, cause danger, experiment can not complete by desired design.Some laboratory, for reaching experiment purpose, adopts a little indigenous method, as carried out control temperature by the method for heat gun or cooling feeder outer wall, but poor effect, the stability of temperature can not be kept for a long time, operate and extremely bother.
Utility model content
For above-mentioned situation, the purpose of this utility model is to provide a kind of constant temperature dropping liquid feeder, with guarantee test material in laboratory environments, is always liquid states of matter, not influenced by ambient temperature, and normal dropping is tested.
For achieving the above object, the technical scheme in the invention for solving the above technical problem is: in the outside of feeder cylindrical shell with constant temperature overcoat.A pressure-equalizing pipe is had on cylindrical shell top.A plug suitable for reading is had at the top of cylindrical shell.There is a constant temperature liquid outlet on the top of constant temperature overcoat side, have a constant temperature liquid import in constant temperature overcoat opposite side bottom.There is a minim pipette in the bottom of feeder cylindrical shell, minim pipette has a baiting valve.Feature of the present utility model increases constant temperature overcoat in the outside of common feeder cylindrical shell, and when needs high temperature, the import of constant temperature liquid connects high temperature circulation oil bath pan or water-bath by pipeline, then form the circulatory system by the outlet of constant temperature liquid with thermal source pot.By circulating pump, high temperature oil or water being entered constant temperature overcoat by the import of constant temperature liquid, is the heating of feeder cylindrical shell, under being in suitable temperature to keep experiment material.For the heating raw materials in dropping liquid feeder is to the temperature that is in a liquid state, and continue to keep temperature constant state.
When needs low temperature, connect sub-cooled circulation pot or frozen water bath.Be connected with constant temperature feeder connector with circulating pump and connecting line, end opening enters, suitable for reading go out, form a circulatory system, for the raw material cooling in dropping liquid feeder can not generating gasification state temperature, and continue to keep temperature constant state.With this feeder can high temperature be no more than 140 DEG C, low temperature be not less than subzero 15 DEG C scope in ensure that material is liquid condition under, long-time constant temperature carries out dropwise operation, and material can not lose, also without any danger.
The utility model is owing to having constant temperature overcoat in the external belt of feeder cylindrical shell: widened range of application, making some is at ambient temperature the material of crystal or solid, or to vaporize lower than room temperature because of boiling point or volatile material remains on liquid condition, ensure carrying out smoothly of experiment, avoid causing experiment cannot operate or measure inaccurate, even produce pressure, cause unnecessary danger.Meanwhile, this constant temperature dropping liquid feeder has the advantage that cost is low, easy and simple to handle, safe, do not need special other auxiliary equipment supporting.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, in the outside of feeder cylindrical shell 5 with constant temperature overcoat 4.There is a pressure-equalizing pipe 2 on cylindrical shell top, have a plug 1 suitable for reading at the top of cylindrical shell.There is a constant temperature liquid outlet 3 on the top of constant temperature overcoat side, have a constant temperature liquid import 7 in constant temperature overcoat opposite side bottom.There is a minim pipette 6 in the bottom of feeder cylindrical shell, minim pipette has a baiting valve 8.
This product adopts glass manufacture, and feeder cylindrical shell can manufacture 100ml, 250ml, 500ml as required.
