Definitions

• Containers for flowable or free-flowing materials in particular for plasters, mortars or the like
• the invention relates to a container for flowable or free-flowing materials, in particular for plasters, mortar or the like, with a frame, a first container held by the frame with an inlet and an outlet and a screw arranged below the outlet of the first container -Delivery pump, which has an inlet which can be optionally connected to the outlet of the first container and an outlet.
• Containers for dry mortar of the aforementioned type are used in a wide variety of designs. These stand containers or stand silos are filled with the plaster / mortar mixture desired by the customer at the building material manufacturer and then brought to the construction site by truck.
• the known containers have a single container for holding the flowable or free-flowing material. Below the outlet of the container there is a continuous mixer with a screw feed pump in order to mix the dry material with water and to convey the mixed plaster / mortar mixture with the screw feed pump. If different plaster / mortar mixtures are to be processed on the construction site, several different containers have so far been required, which complicates handling.
• the invention has for its object to provide a container for flowable or free-flowing materials, in particular for plasters, mortars or the like, with which it is possible to choose between several materials.
• the invention proposes a container of the type mentioned at the outset, which in addition to the first container is provided with at least one second container which can be connected or is connected to the frame and / or the first container, the at least one second container having an inlet and an outlet which can optionally be connected to the inlet of the screw feed pump has and the at least one second container is designed in its shape and configuration such that it does not or does not protrude significantly beyond the outer contour defined by the frame and / or the first container.
• the invention thus proposes a stand container that can be transported by truck and has a first ⁇ main) container and at least one second (additional) container.
• the outlets of these at least two containers can optionally be connected to the screw feed pump in order to pump either the plaster / mortar mixture of the main container or that of the additional container, which has been mixed with water.
• the arrangement and design of the at least one second container is selected such that it is located within the outer contour defined by the first container and the frame of the container or does not project significantly beyond it.
• the volume of the first container is preferably approximately ten times the volume of the second container.
• One or more second containers can be arranged on the frame or the first container, it always being the case that the second container or the second containers do not or not substantially over the outer contour of the frame and / or the first container Containers survive.
• the container according to the invention can be used particularly advantageously where it is a matter of applying a base coat as well as a top coat to a facade.
• the first is used to hold the base coat (Main) container while the plaster is being placed in the second (additional) container.
• the processing quantity of basic plaster far exceeds the processing quantity of the finishing plaster, which is more expensive than the basic plaster.
• two different plasters can be transported from the manufacturer to the construction site, where they are processed.
• the "disappearance" of the at least one second container in the outer contour defined by the frame and / or the first container of the container brings advantages in terms of transport technology in that the same vehicles as previously can be used to transport this container.
• the processing of plasters of different qualities also requires different conveying capacities.
• the container according to the invention is therefore expediently provided with a screw feed pump which can be adjusted in its delivery rate.
• a screw feed pump which always applies the maximum torque at different feed rates, ie only changes the throughput per unit time, that is to say the feed rates can be set differently at the same feed pressure.
• the second container in an advantageous development of the invention, provision is made for the second container to be arranged within the first container.
• the inlets of both containers are then to be led out of the first container in order to be able to fill both containers from the outside.
• the two containers are then essentially of the same length.
• the development described here represents an advantageous measure.
• the first container has an essentially unchanged cross-section, the upper section encompassing the inlet and a lower section, which in particular tapers conically up to the outlet, and that the second Container is arranged in the region of the lower section of the first container outside the same.
• the free space that is given between the frame carrying the first container and the conically tapering section of the first container is thus used.
• the frame normally comprises at least three vertical legs which are connected to and support the first container in the region of its upper section or in the transition region between its upper and lower section. The space between the vertical legs arranged on the outside and the conically tapering lower section can then be used to accommodate the second container or containers.
• the at least one second container is expediently attachable to the first container or the frame by means of a forklift or similar industrial truck.
• the outlets of the two containers can preferably be connected or are connected to separate inlet openings of the inlet of the screw feed pump or of the continuous mixer. It can also advantageously be provided that the at least one second container is displaceably guided on the outside of the first container, that is to say it can be moved on the outside of the first container along a circular line. The second container can thus be moved with its outlet via an inlet opening of the inlet of the screw feed pump or the continuous mixer.
• the continuous mixers of the usual containers have a fixed one next to theirs the outlet of the single container connected opening a further inlet opening, which is used for feeding bag goods.
• an additional container according to the invention is provided in such a container, it can be moved over the sack feed opening of the continuous mixer for the duration of the removal of the material in it.
• the displaceability of the additional container on the main container can also be advantageous in order to be able to change the position of the additional container during transport and during use. This in turn offers the possibility of optimizing the load distribution during transport.
• This position of the second container which is advantageous for transport, can be disadvantageous, depending on the orientation of the continuous mixer or the screw feed pump and the arrangement of its inlets, so that when the container is stationary, the second container is then via the respective inlet of the continuous mixer or Screw feed pump can be moved or pivoted.
