Description

DETERGENT DOSING MACHINE

OBJECT OF THE INVENTION

The invention, as expressed in the statement of the present specification, refers to a detergent dosing machine, which contributes to the function to which it is intended, advantages and novelty characteristics that will be described in detail below and which suppose a improvement of the current state of the art.

More particularly, the object of the invention is centered on a machine whose purpose is to dilute solid detergents and dose them once diluted to facilitate their use in industrial washing machines, car wash tunnels or other applications that require the continued use of this type of detergents

FIELD OF APPLICATION OF THE INVENTION

The field of application of the present invention is part of the industry sector dedicated to the manufacture of machines and product dosing devices, focusing on the specific field of detergent dispensers.

BACKGROUND OF THE INVENTION

As is known, there are multiple applications in the industry in which detergents are used continuously to carry out a specific task. Such is the case of industrial washing machines, for example clothes or car wash tunnels.

The problem arises when the detergent that is used is distributed in a solid way since in this way its acquisition is usually much more profitable and, on the other hand, it also has the advantage that the proportion of water with which it is used can be better controlled. You want to dilute to obtain the optimal results that are sought in each case.

However, the task of diluting said detergent in water, in the case of the aforementioned industrial applications, can be an arduous job, for which, until now, only large machines are known that are very expensive to acquire, complex to handle and difficult to transport, since in most cases they are designed for large-scale industrial processes.

It would be desirable, then, to have a machine for dosing already diluted solid detergents in applications that, being of industrial type, are not large-scale and can be carried out with a simple-to-use machine and reduced economic cost, also allowing its easy installation and transfer, the essential objective of the present invention being the development of said new type of machine.

EXPLANATION OF THE INVENTION

Thus, the detergent dosing machine that the invention proposes is configured as a remarkable novelty within its field of application, and with which, according to its implementation and in a restrictive way, the objectives previously indicated as suitable are satisfactorily achieved, being the characterizing details that make it possible and that distinguish it from what is already known, conveniently included in the final claims that accompany the present description thereof.

Specifically, what the invention advocates, as already noted above, is a machine specifically designed to store, dilute and dose solid detergents for use as a detergent diluted in washing tunnels, industrial washing machines or other similar applications, presenting the advantage of being made up of a compact set of small dimensions, approximately 70cm wide, 130cm long and 130cm high, which allows to reduce its economic cost and facilitate its installation.

More specifically, the recommended machine is configured from a metal support structure to which all its components are anchored, comprising a hopper for depositing the powdered detergent provided with stirring blades inside, which, moved by a First electric motor-reducer, prevent lumps of solidified powder from forming and keep it loose to make it fall into a bottomless auger that, driven by a second electric motor-reducer, feeds a bucket where it mixes with the water to be diluted .

Said bucket, meanwhile, is associated with a third motor-reducer that moves an agitation system of the same to ensure the mixing of the detergent with water, water that is introduced into the bucket from a conduit suitable for connection to a tap supply, optionally using connection hose and in which a first pneumatic solenoid valve is provided to open and close the passage thereof.

The machine also has a pulse counter device for dosing the inlet water to the cuvette as well as a second pneumatic solenoid valve connected to said device to open and close the water inlet to the cuvette.

For its part, the product outlet of the cuvette is connected to a membrane pump that, conveniently connected to an air pressure regulator, sends the product to the machine or machines washed where required, with a third solenoid valve being provided. pneumatic that controls product emptying.

Finally, the machine includes a programmable PLC to control the aforementioned solenoid valves and filling, agitation and emptying maneuvers, arranged in a sealed box, in which, in addition, the electrical elements of the machine are contemplated, comprising, at least, a differential three-phase, three-phase and neutral circuit breaker of maneuver parts, three-phase contactors to control the maneuvers, transformer 220 to 24 volts and terminal strips for connections.

In view of the foregoing, it is found that the aforementioned detergent dosing machine represents an innovative structure of structural and constitutive characteristics unknown until now for the purpose to which it is intended, reasons that, together with its practical utility, provide it with a sufficient basis to obtain the exclusivity privilege requested.

DESCRIPTION OF THE DRAWINGS

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, this descriptive report is attached, as an integral part thereof, of drawing, in which with an illustrative nature and not limiting the following has been represented:
