DE973827C - Device for the uninterrupted production of soap foam, in particular resin soap foam for the production of foam concrete - Google Patents

Description

They are devices for the continuous production of foam known to consist of a closed vessel with a lower one directed upwards Air inlet and an upper downward outlet for the foam formed exist. In these devices, the compressed air is passed through a column of water blown at a constant height, creating a large-bubble, containing excess moisture Foam is formed, which is only due to the action of a mechanically driven Agitator must be converted into fine-bubble foam. As a result, the known device cumbersome and expensive to use.

Furthermore, hand tools for making foam are not new, both of them Close-meshed sieves are installed in the outlet through which a batch-wise fed A jet of a soap solution is foamed. This handheld device is designed to be continuous Production of an even, fine-bubble and dry foam is not suitable.

The mentioned disadvantages are avoided by the new device, according to the invention as a feed for the liquid to be foamed in a closed container one directed in the opposite direction to the rising air flow Feed pipe is arranged with an upstream distributor plate.

The liquid to be foamed and exiting through the supply pipe is distributed like a veil by hitting the distributor plate and then through the rising air flow in the form of a mist through an existing one in the outlet Sieve transformed into fine-bubble, dry foam.

It is useful to place a piece of pipe on the outlet connection of the device to postpone, which can be adjusted in its position to the foam outlet opening can to the resulting soap scum in a more or less summarized Let form emerge.

In the drawing, a useful embodiment of the new device is shown. With a. denotes a fan, the air discharge pipe b of which opens into the lower end of a dome-like container c, in which a horizontal sieve d penetrating the container is arranged in the lower part. At some distance above this sieve d opens a downwardly guided pipe e, through which a fine, adjustable amount of soap solution can be introduced into the container c from a storage container. At the lower end of this pipeline e, which can be shut off by a valve g, a distributor plate lt is attached, through which the soap solution flowing down is transferred into a thin veil. Due to the compressed air entering from below and rectified through the sieve d, the curtain of the soap solution is sprayed into a mist, which is conveyed out of the nozzle i of the container c by the air flow, with the mist through a fine-meshed sieve k inserted in the interior of the nozzle i transformed into lather and constantly being discharged. A pipe section m is pushed onto the outlet nozzle i , the position of which can be adjusted in relation to the foam outlet opening in order to be able to let the foam soap emerge in a more or less summarized form.

At the lower end of the container c an outlet n is provided, through drained the soap liquid that has accumulated in the lower part of the container c can be.
