METHOD AND PROCESS FOR PROVIDING A STRUCTURAL REINFORCEMENT TO A WATER TANK

Abstract

The present invention belongs to the field of devices for storing drinking or non-drinking water, more specifically to water tanks and large capacity water reservoirs, characterized in that a structural reinforcement is provided which withstands greater mechanical loads, in particular on the edges thereof, which loads cause cracks or fissures that damage the entire reservoir in the known prior art models.

PREFERRED ARRANGEMENT

[0015] As illustrated in the above drawings, the water tank, conventionally obtained by the method and process for providing a structural reinforcement to a water tank (01) is composed of a highly resistant material reinforcement (02) fastened to the edges thereof in a stage prior to shaping, by rotomolding process, with a view to tightening and distributing the loads imposed on the edge.

[0016] Having applied this reinforcement (02), which may be a metal alloy, polymers are converted into a highly resistant structure, this structure being disposed in accordance with the geometry of the part to be obtained, and may have a circular or rectangular section or any other geometry that the format of the reservoir body requires. Once the structural reinforcement is disposed, the construction material of the water tank or reservoir (01) is subject to a rotomolding process.

[0017] In the rotomolding process, the raw material is placed in a mold, essential supported by a primary shaft and a secondary one, and this mold is operatively associated to a heat source, such that it is simultaneously heated and turned, forcing the particles to deform and melt onto the female mold without the need for applying external pressure or centrifugal force.

[0018] In a second stage, the mold is designed to cool, while it turns around the two perpendicular shafts. Cooling is by air currents obtained from a source installed on the equipment itself, preferably a ventilator sized proportionally to the mold, and cooling is completed by jets of water, equally obtained from an external source. Once cooled, the part is withdrawn from the mold already incremented at its marginal portions, more particularly at the edges as a means of reinforcement.

[0019] The process of obtaining the water tank, as already described, provides a means of absorbing the loads imposed upon the single body of the tank or reservoir by distributing the loads imposed by the means where it is installed. Further, the process described above provides the structuring of the part by means of reinforcement in the manufacturing process itself, preventing deformation and maintaining the upper diameter of the water tank or reservoir once the polymer has cooled.

[0020] Although just one constructive arrangement of the present patent of invention has been illustrated herein, it should be understood that alterations in shape and arrangement can be made in the different stages of the method and process for obtaining structural reinforcement in a water reservoir, without straying from the constructive concept defined in the claims accompanying the present specification, also including a plurality of materials to be disposed as structural reinforcement element.
