Device for atomizing and introducing a liquid release agent into molds for the production of finished parts, especially precast concrete parts

The innovation relates to a device for atomizing and introducing a liquid release agent in molds for the production of prefabricated parts, in particular precast concrete parts, with a pressure-resistant, the release agent receiving container, into which a pressure medium, preferably air, can be introduced through a valve device and which is provided with a valve-controlled atomization device for dispensing the release agent or is connectable.

In the manufacture of prefabricated parts in the construction industry, in particular prefabricated concrete parts, molds are used into which a concrete mixture is poured which, after solidification and setting, forms a prefabricated part to be removed from the mold. Before the concrete is poured , it is easier to shape

a liquid release agent introduced into the mold, with which the walls of the mold are wetted. This release agent must in order to function properly meet, be atomized as very finely as possible, so that it appears as a mist consisting of fine droplets is reflected on the mold walls.

So far, pressure-resistant bottles have been used to introduce the release agent into the finished part molds provided with an atomizing device or ver are bound. These bottles are also single handed pumping device provided, with the similar to that of atomizers for insecticides By pumping for a long time, a pressure is generated in the container above the liquid level by means of pumped-in air can be, which then enables the atomization of the release agent. However, this known mode of operation is disadvantageous because it is not always flawless Atomization of the release agent required minimum pressure is built up because this depends on the duration of the manual len pump actuation depends. In addition, in particular at relatively low pressure values, such a pressure can quickly be reached in the container that practically none Atomization takes place more and the pump actuation must be repeated relatively often.

Overall, this method of working results in delays in the production of prefabricated parts, which on the one hand on time lost to generate pressure in the release agent containers, on the other hand on difficulties in the shaping of the prefabricated parts as a result can be attributed to the atomization of the release agent.

The task of the innovation is to create a device that allows manual generation of the Makes atomization pressure in the container superfluous and also ensures that each container fill ment for perfect atomization of the release agent

Sufficient pressure is generated in the container.

A device mentioned at the beginning is for the solution This object is designed according to the innovation such that a screwable to the container filling connection for the pressure medium is provided, which acts as a hanger for hanging the container on an in a supply line designed for the pressure medium provided check valve and for this purpose with an opening device known per se provided for the check valve 1st.

The innovation makes it possible to use one and the same filling connection for several separating agent containers. In the factory producing the prefabricated parts, only a supply line, for example for compressed air, has to be installed, into which one or more check valves are then to be inserted, on each of which a separating agent container can then be hung. The opening device can be designed as is the case, for example, with the known compressed air tanks at gas stations, ie it can contain a downwardly pointing opening pin which acts on the valve element of the check valve in the supply line when the container is suspended. A major advantage of the innovation is that the filling connection can easily be designed in such a way that it is simply screwed into existing separating agent containers instead of the hand pump device. A check valve is usually already provided at the corresponding opening in the container, which check valve can remain in the container even when the device according to the invention is used. If such a check valve is not available, it can be built into the filling connection at any point.

The filling connection is expediently provided with a handle so that the entire container with the screwed-on filling connection can be conveniently handled with it

and can be hung on the check valve in the supply line for the pressure medium.

In a further development of the concept of innovation, the filling connection has a pressure reducer. This is useful because compressed air lines in industrial systems usually have a very high pressure lead, which has a higher value than the pressure permissible for a release agent container. In this case it will the pressure of the supplied pressure medium or the pressure reducer built into the connection piece Compressed air reduced to the value permitted for the release agent container.

A particularly simple and cost-saving design of the device according to the invention then results when the filling connection can be screwed into a filling opening on the top of the container vertically running connection piece, a laterally extending beyond the container, to the connection piece connected connecting pipe as well as the opening device attached vertically to it with the pressure reducer having. In this case, the filling connection only consists of straight pipes that are connected to one another can be welded or screwed. Appropriate the connecting pipe protrudes laterally only so far beyond the container that it is suspended on a non-return valve hangs approximately vertically on the supply line. If necessary, the check valve can also be used be built into the supply line at a slight incline, so that it then also slopes slightly at an angle of the release agent container is possible. However, if this leads to difficulties in opening the check valve, for example, a spacer element can be attached to the wall of the workroom holding the supply line below the line be provided, on which the release agent container rests in its lower area.
