and similar masses.

Patented in the German Empire on April 1, 1908.

The invention relates to a method and a device for moistening and Extinguishing plaster, cement and similar masses with water.

Devices are known by means of which plaster of paris or similar powdered masses be passed uninterruptedly and calmly through water for the purpose that Masses without being poured over or rummaged around,

ίο and without the walls of the extinguishing vessel to be stained, dampened and erased by the masses.

In those known devices, the plaster of paris is from a hopper to one Conveyor belt guided, which gradually and calmly guides the plaster through the water and the gives off saturated plaster of paris. A gate or slider is used to prevent too much of the plaster of paris flows onto the belt. When using such a slide it was found that he the Plaster of paris or the extinguishing material smooths and compresses something so that the saturation of the Can't do something good with water quickly enough.

According to the invention, the smoothing of the mass is not only avoided, but the After leaving the feed hopper, the mass is furrowed and roughened or roughened loosened up in a different way, with good results in two directions. First, the mass is loosened so that it saturates itself quietly, and on the other hand it is through The roughening of the mass increases its surface area significantly, so that the water rises the enlarged area can penetrate into the mass and thus not through alone the loosening, but also by the enlargement of the surface the impregnation the crowd is greatly relieved. It is clear that the loosening or the roughening can be accomplished in various ways and the invention is therefore not limited to a particular embodiment of a Device for performing the method is limited.

There are also known roughening devices in which a sawtooth-shaped Sheet solidifying masses roughened for the purpose of connection with new layers to be applied or for patterning the surface provided with jagged or circular furrows; sawtooth blades are also included Mixing machines found use where they knock over the mix and thereby the Mixing effect. In contrast, according to the invention by means of roughening sawtooth-like leaves or similar roughening the surface for water entry enlarged and the good loosened up.

The drawing shows an apparatus for carrying out the method in one embodiment illustrated.

or furrowing the mass serving slide. »The device is stored on a frame ίο. It consists of a conveyor belt ii which runs over drums 12 which are carried by shafts 13 and one of which is driven in any desired manner. The conveyor belt runs at one end under a feed box 14 and is guided horizontally by a roller ΐ6δ, which is located under the upper part of the conveyor belt. The feed box 14, which is narrower than the conveyor belt, is mounted under the hopper 15, from which it ο the plaster. the like. A pusher 16, which can be moved up and down and fastened by means of a bolt 19, enables the speed at which the mass is guided onto the conveyor belt to be regulated by determining the depth of the ceiling that the plaster of paris should form on the conveyor belt , regulates. The plaster of paris, mortar or other similar masses are moved through a container, where they are soaked calmly but quickly and completely. The impregnated mass is then moved over the second drum 12 and scraped off by a scraper 18. If the slide 16 is smooth or straight at the lower end, it shows the tendency to smooth the mass and compress it somewhat so that the mass layer would not be saturated quickly enough. To avoid this inconvenience, the lower edge of the slide, as shown at x6a in Fig. 3, is designed like a sawtooth, or a roughening plate 20 is attached to the feed box behind the slide and this plate is toothed at 21 according to FIG if you want the lower edge of the slider itself to remain smooth. The teeth cause the mass to loosen up and give it an irregular surface that is larger than the smooth, flat surface and accordingly results in the mass becoming saturated with water very quickly. The illustrated form of the device is not essential, with the exception of the arrangement of the conveyor belt, which must always be passed through the saturation tank, while any known device for loosening, furrowing or roughening can be brought into contact with the surface of the mass for the purpose to achieve the invention. Godparents τ-Α ν Proverbs: 1. Procedure for moistening and extinguishing plaster of paris, cement and the like Masses by passing the mass through a water bath, characterized in that that the mass is loosened and roughened on the surface before it enters the water bath, in order to prevent it from entering of the water to ease into the bulk. 2. Apparatus for carrying out the method according to claim i, wherein the mass to be moistened or extinguished by means of an endless conveyor belt a liquid container is passed through, characterized in that on the At the mouth of the filling box, a slide provided with a sawtooth-like lower edge is attached above the conveyor belt is whose teeth mesh with the mass to loosen and roughen it. 1 sheet of drawings.
