SPECIFICATION
Improvements in or relating to Washing Devices
The present invention relates to washing devices for fitting to apparatus for example, and particularly to analysis combustion devices for treatment of organic substances, which devices can be fitted to a container such as an absorption bulb and have a tube for introductions of washing liquid.
As an illustration of the applicability of such devices, a method and device for the determination of trace elements in organic substances in such combustion devices are described in German patent 1 032 000, for example.
Moreover, a continuously operating detonating or oxyhydrogen gas combustion device for the quick and regular treatment of substances in organic elementary analysis is described in German patent 1 498 722 for example.
On insertion of definite substances to be treated, residues can remain in the containers of the combustion apparatus, which containers may be in the form of absorption bulbs.
It is an object of the invention to provide a simple washing device for such analysis apparatus, especially for a combustion apparatus for treatment of organic substances, which can be fitted to a container such as an absorption bulb. The washing device should make possible and intensive washing of the entire inner surface of a container.
The invention accordingly consists in a washing device arranged to be fitted to a container such as an absorption bulb and which has a tube for supplying a washing liquid wherein said device has a circular channel which a washing liquid is caused to flow tangentially via a tube and at this point has a narrowed passage which opens into a male part of a ground-in joint.
The construction according to the invention has the advantage that the inner surface of a container which comes into contact with a substance which has to be treated is cleaned or kept clean by a film of a washing liquid which wets the entire surface. This film of washing liquid can form readily thanks to the construction of the device according to the invention and trickle down onto the entire inner surface. Exchange of the container because of container because of contamination is no longer necessary.
Advantageously, a washing device according to the invention is made so that it can be easily exchanged and can be sealingly connected to the container to be washed.
In order that the invention may be more clearly understood, reference will now be made to the accompanying drawings and which schematically show one embodiment thereof and in which:—
Fig. 1 is a section along the line C—D in Figure 2, and
Fig. 2 is a section along the line A—B in Figure
1.
Referring now to the drawings, the washing apparatus shown which takes the form of a cap or plug, has a circular channel 1 in its upper part into which a washing liquid is filled tangentially through a tube 2, which latter is preferably in the form of a capillary tube. In the upper part of the cap or plug, a narrowed passage is provided which is connected downwardly to the tube 2 i.e. in the direction of the flow. The narrowed passage opens into a male part of a ground-in tapered joint 3. The male part of a ground-in joint 3 sealingly engages a correspondingly formed receiver neck or collar. The male part of the ground-in joint preferably terminates within this neck or collar associated with a container 6 and which is also ground to suit. The container may take the form of an absorption bulb.
A control tap 4 is built into the tube for the washing liquid so as to control the inflow of liquid.
A tube 5 is inserted into the central area of the upper part of the cup or plug, its free end protruding out of the male part of the joint 3. The tube 5 can serve as a suction tube but it can also serve for introduction of gases, liquids, or mixtures. The washing apparatus is advantageously made of glass or quartz glass.
Due to the fact that the washing liquid is introduced tangentially and preferably under pressure, the liquid is rotated as it is fed to the channel 1 and runs from there downwards simultaneously cleaning the inner surface of the container 6. The ground connection at 3 is so formed that the main part of the ground-in joint has thin walls and further ends within the collar of the container 6. This has the advantage that the liquid film is transferred to the neck of the container 6 without being removed from the male part 3. At a pressure differential of 100 millibars between the pressure inside the container 6 and the pressure in the tube 2, the liquid enters at so high a speed that a fast rotating liquid film, which is stablised by centrifugal force, is formed within the channel 1. In this case the capillary tube 2 has an internal diameter of only 1.5 millimeters.
The end of the tube 5 is so located in the neck (e.g. angled, bent, or slanted) that the lower end of this tube prevents intake of drops of the absorption solution into the container 6.
Claims (8)
Claims
1. A washing device arranged to be fitted to a container such as an absorption bulb and which has a tube for supplying a washing liquid, wherein said device has a circular channel which a washing liquid is caused to flow tangentially via a tube and at this point has a narrowed passage which opens into a male part of a ground-in joint.
2. A washing device as claimed in claim 1, wherein a control tap is built into the tube.
3. A washing device as claimed in claim 1 or 2, wherein the tube is formed as a capillary tube.
4. A washing device as claimed in claim 1,2 or 3, wherein the male part of the ground-in joint is arranged to terminate within the neck of a ground connection of a container.
