Embodiment Construction

[0029] figure 1 Shown is a system 1 for mixing chemical products such as phytosanitary products with water. The system 1 comprises a water inlet 3 for connection to a pressurized water supply such as a garden hose or the like. The system 1 also includes a chemical product inlet 5 for connection to a chemical storage tank. Finally, the system 1 also comprises a mixture outlet 7 through which the mixture of water and said chemical product can flow, for example, to a garden hose or nozzle.

[0030] The system 1 comprises a main pipe 9 arranged between the water inlet 3 and the outlet 7, in which main pipe the water flows in the direction of the arrow F1. The upstream side of the system 1 is located on the side of the water inlet 3 , and the downstream side is located on the side of the outlet 7 , and the upstream and downstream sides are defined relative to the direction of water flow in the main pipe 9 .

[0031] According to the invention, the system 1 comprises a main chamb...

Abstract

This system (1) for mixing a chemical product with water comprises a water inlet port (3) designed to be connected to a pressurized water supply pipe, a chemical product inlet port (5) designed to beconnected to a reservoir (100) of chemical product, and a mixture outlet port (7). It comprises a main chamber (11) in which there can move a piston (13) delimiting an upstream part (15) of the main chamber (11) fluidically connected to the water inlet port (3) and a downstream part (19) of the main chamber (11) connected to the chemical product inlet port (5), the piston (13) being equipped witha rod (130) extending into the downstream part (19) of the main chamber (11). The water inlet port (3) is also connected to the mixture outlet port (7), the downstream part (19) of the main chamber (11) is also connected to the mixture outlet port (7). A water flow rate regulating device (60) is interposed between the upstream part (15) of the main chamber (11) and the water inlet port (3). The piston (13) is able to move, in the main chamber (11), under the action of the incoming water entering the upstream part (15) of the main chamber (11) and of the difference in pressure created by the rod (130) of the piston (13) in the downstream part (19) of the main chamber (11) so that chemical product contained in the downstream part (19) of the main chamber (11) is directed toward the mixture outlet port (7).

Description

technical field [0001] The invention relates to a system for mixing chemical products such as plant protection products with water. Background technique [0002] In the field of mixing systems of phytosanitary products with water, there is known a mixer using the Venturi effect, in which a certain amount of product is sucked in by means of a partial vacuum created by circulating water in a limited cross-section, thereby obtaining mixture. Such devices are imprecise and require the use of large amounts of circulating water. [0003] There are also mixers that inject chemicals into a water stream by using a volume of water to exert pressure on a membrane, causing the membrane to expand. Such systems are dependent on the viscosity of the fluid to be dispensed and cannot allow simple adjustments to the dose dispensed. Contents of the invention [0004] The present invention aims to solve the above-mentioned disadvantages, especially by proposing a new type of mixing system ...
