Definitions
- the invention relates to a thin-walled collecting container made of plastic, in particular for sewage lifting plants.
- Collection tanks for sewage lifting plants are subject to the provisions of DIN 1986 and the Institute for Building Technology, which impose minimum requirements on tightness, corrosion resistance and safety against bursting under pressure. This Requirements with thin-walled collection containers are only reliably met up to a container volume of approximately 150 liters. If the collection containers are manufactured using the rotary sintering process, which only allows wall thicknesses of up to 10 mm, then the limit for this size, which is favorable in terms of production technology, has been reached in this size.
- the invention has for its object to provide a thin-walled collecting container made of plastic that absorbs deformation forces acting on it without impairing its safety or its function in the context of a system, which is particularly suitable for holding a larger volume of liquid in compliance with the applicable safety rules .
- the basic idea of the invention is not to stiffen the container in the critical zones as usual, but to make it deliberately soft and flexible there.
- the deformation caused by the forces to be taken as a basis on the basis of the safety regulations can therefore already occur at the Design of the collecting container are taken into account, so that there are no harmful effects on its safety and for the function of the system.
- Fig. 1 shows the side view of a collecting container with two centrifugal pumps arranged on its top and in the
- the collecting container (1) which is equipped with various pipe connections (2) for supply and discharge pipelines, has on its top a rigid plate (3) made of metal that is firmly connected to the plastic wall. With this plate (3) two centrifugal pump units (4) projecting into the interior of the collecting container (1) are screwed (only the electric motor of the front unit is visible in the drawing).
- the plate (3) also carries a pressure port (5) with - not shown - integrated switching flap. For example, one of the two centrifugal pump units (4) can deliver waste water from the collecting tank (1) into a pipeline to be connected to the pressure connection (5).
- the collecting container (1) can be set up separately or in a battery arrangement with further collecting containers.
- the collecting container (1) has two prepared connections (6) on both long sides, which are made ready for connection by removing a wall cutout.
- FIG. 2 an area enclosed by a dash-dotted circle is highlighted, which is shown as a detail in FIG. 3.
- the corner (7) has approximately the shape of an omega. As shown in FIG.
- the corner (7) bends like a spring when the internal pressure is greatly increased, thus reacting with a deformation that is harmless to the wall.
- the dashed line shows the corner (7) in the unloaded state, the solid line represents the wall profile of the deformed corner (7).
