Abstract
The utility model relates to a glass burr back flow belongs to backward flow condensation device field, comprises inner tube, outer tube, and the inner tube is the opening from top to bottom, and inner tube top is spherical, and lower partial in one plane is followed the backward flow pipe wall and is stretched out 3 " cold bubbles " in opposite directions, just communicates with each other between " the cold bubble ", becomes " burr " shape, outer pipe box is even on the spherical upper portion of inner tube, and there is the slope water filling port on outer tube upper portion. Based on this kind of structure, the utility model discloses when the sample is cleared up, can economize on water through the forced air cooling, just can block passing through of volatile materials and steam, have better backward flow effect.
Description
Technical field
This utility model relates to reflux condensation mode apparatus field, in particular for a kind of glass burr return duct on COD digestion device.
Background technology
Reflux condensing tube is a kind of glass tubing equipment realizing backflow functionality commonly used in organic chemical industry's experimentation, is arranged on reflux and coordinates with distilling flask, bent adapter tube, does condensed steam and cohesion drop is used.Reflux condensing tube is according to purposes separating-ball-type, Serpentis type, straight type etc., it is adaptable to the units such as scientific research, universities and colleges, petrochemical industry, pharmaceuticals industry, health care.
Simultaneously, reflux condensing tube is also the important component part of COD digestion device, general COD digestion device uses the glass spherical return duct, by circulating water, when carrying out Specimen eliminating, the sample in bottle is cleared up in heating, have a small amount of volatile material and steam to be overflowed by spherical return duct, being unfavorable for reflux cooling, and waste water, measurement result is cleared up in impact.
Utility model content
For the problem of shortcomings and deficiencies in prior art, the utility model proposes a kind of glass burr return duct, when Specimen eliminating, by air-cooled can water saving, and passing through of volatile material and steam can be stopped, there is more preferable reflowing result.
This utility model solves its technical problem and be the technical scheme is that
A kind of glass burr condensing tube, is made up of inner tube, outer tube, lower port in inner tube, and inner tube top is divided into spherical, and lower part in one plane stretches out 3 " cold bubbles " in opposite directions from condensation tube wall, and communicates between " cold bubble ", becomes " burr " shape；Outer tube sleeve is connected in the bulbous upper portion of inner tube, and inclination water filling port is arranged at outer tube top.
Further, said inner tube is suitable for reading for funnel shaped.
Further, described outer tube outer wall Shang You frosted district.
This utility model has the advantages that glass burr return duct inner tube top is divided into spherical, and catalyst thus adds the moment of light component in sample can be stoped to volatilize；Lower part " burr " shape more increases film-cooled heat than simple spherical return duct, and can stop passing through of volatile material and steam, and this utility model, by air-cooled, can be economized on water, can add water cooling, play safety effect at the outer tube of top.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further.Should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model.In addition, it is to be understood that after having read the content that this utility model is lectured, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims limited range equally.
As it is shown in figure 1, this utility model is made up of inner tube 1, outer tube 2, lower port in inner tube 1, inner tube 1 top is divided into spherical 10, and lower part in one plane stretches out 3 " cold bubbles " in opposite directions from backflow tube wall, and communicates between " cold bubble ", becomes " burr " shape 11；Outer tube 2 set is connected in spherical 10 tops of inner tube 1, and inclination water filling port 20 is arranged at outer tube 2 top.
The outer tube outer wall Shang You frosted district 30 of glass burr return duct, is fixed to glass burr return duct in COD digestion device equipment in position, frosted district 30, and return duct end opening 22 is connected with clearing up bottle.Before Specimen eliminating, outer tube water filling port 20 add distilled water as much as possible, to its safety effect air-cooled, to ensure cooling effect.Catalyst is added by bell mouth 21, and bell mouth 21 avoids the problem spilt or overflow outside the catalyst added in inner tube 1.Return duct top is divided into spherical 10, and catalyst thus adds the moment of light component in sample can be stoped to volatilize.Clear up in bottle sample heated after, volatile material and steam rise into return duct bottom, return duct bottom is divided into " burr " shape 11, in one plane stretch out 3 " cold bubbles " in opposite directions from backflow tube wall and more increase film-cooled heat than simple spherical return duct, and passing through of volatile material and steam can be stopped, by carrying out air-cooled to lower section burr pipe, add the safety effect of upper part spherical return duct inner cooling water, can better assure that back flow of sample cools down.
