Definitions

  • the present invention refers to a method and system for pumping water from a flexible container with a thin internal bag through a pump through an intermediate air box.
  • Flexible containers (2) are used to transport and supply water and other liquids ("water”) in a variety of cases.
  • Flexible tank (2) includes a strong flexible outer layer made of materials such as PVC and PE and a thin flexible inner bag (3), which can be approved for food when transporting drinking water.
  • the flexible tanks (2) include a discharge hole (21) from which the water is drawn from the flexible tank (2).
  • pump (5) In flexible tanks (2) with a volume of 200 liters and more it is customary and needed to use pumps (5) with pumping capacity of hundreds of liters per minute. In such cases, when all the water is pumped out from the flexible tank (2) the pump also draws the inner bag (3), which is a problem that the present invention is designed to solve.
  • DESCRIPTION OF THE DRAWINGS DESCRIPTION OF THE DRAWING

  • Another object of the present patent application is to describe a method for pumping water from flexible tanks (2) using a pump (5) without the internal bag (3) being sucked out, using the intermediate air box (4).
  • the structure and design of a flexible tank (2) for transporting water with a thin inner bag (3) and which includes a discharge hole (21) is known to experts in the field and therefore it is not necessary to describe this structure in the present patent application, and it is the same as to the pump (5) with the pumping tube (51) which are designed to pump water from the flexible tank (2).
  • the intermediate air box (4) is designed as a closed box that includes a water inlet (41) with a connecting adapter (61) to the discharge hole (21) of the flexible tank (2), a water outlet (42) with a connecting adapter (62) to the pumping tube (51) of the pump (5), and an upper air intake opening
  • the upper air intake opening (43) can be closed with a one-way valve
  • FIG. 1 describes schematically the system (1) that includes the flexible tank (2), the pump (5) and the intermediate air box (4).

Abstract

L'invention concerne un système comprenant un réservoir souple permettant de transporter de l'eau, doté d'un sac interne souple et d'un trou de vidage, une pompe dotée d'un tube de pompage et une boîte à air intermédiaire comportant une entrée d'eau, une sortie d'eau et une ouverture d'air supérieure. Lors du raccordement de la pompe à la sortie d'eau et du réservoir souple à l'entrée d'eau, l'eau s'écoule du réservoir souple dans la boîte à air intermédiaire jusqu'à ce que l'entrée et la sortie d'eau soient sous le niveau de l'eau. La pompe pompe l'eau à partir de la boîte à air intermédiaire et, par conséquent, du réservoir souple et, lorsque le réservoir souple a été vidé, le niveau d'eau dans la boîte à air intermédiaire baisse sous le niveau de la sortie d'eau et, par conséquent, la pompe pompe l'air qui s'écoule à l'intérieur de la boîte à air intermédiaire par l'ouverture d'air supérieure et le sac interne souple n'est ainsi pas aspiré à l'extérieur.
