Description

Water surplus evacuation system in beer cooling vats.

Object of the invention

The present invention relates to a device for the evacuation or elimination of excess water accumulated in the beverage cooling vats, especially beer, specifically in the vats in which the coils are set that relate the beer barrel (s) to the beer corresponding faucets.

The object of the invention is to achieve a system that makes it absolutely impossible for the water level in the inside the tank reach the drive motor of the classic agitator, in turn preventing said engine from being damaged for a short circuit if the power supply is not interrupted electric of the same.

Background of the invention

In beer supply facilities of barrel and as is known, between the barrel and the corresponding tap a cooling or cooling system of the beer, consisting of a refrigerating equipment, whose evaporator is housed in a tank full of water, so that in the beer circuit from the barrel to the tap a coil that is housed in the tank and in which the cooling of said beer. When the establishment dispenses several different types of beer and for obvious reasons economic, cooling coils coming from corresponding barrels are located in the vat of a team Unique refrigerator, common to all of them.

In order to get the temperature in the inside the tank is homogeneous, immediately above the mouth of the tank is established a drive motor of a agitator whose propeller removes water inside the tank, in noticeably centered layout.

To get in the transfer water thermal a suitable temperature, the evaporator of the system refrigerator must reach temperatures significantly below 0 °, so that it is always embedded in a cylinder of ice.

Because of the environmental humidity and the effect of condensation, the water level grows slowly and progressively in the within the tank, so that conventionally and at the appropriate level establishes a drain overflow that, at least theoretically prevents the water level from reaching the agitator motor.

There is a tendency to ice generation in this perimeter zone, frequently arriving at the situation of that the overflow is filled with ice or is isolated from the area of water due to the formation of an ice barrier preventing overflow of water, and can continue to increase the height of the ring of ice to levels in which said agitator motor is partially submerged, the deterioration appearing as the first fault of the lower bearing, and continuing with the consequent e unavoidable short-circuiting of your windings or any others elements under tension, with the consequent breakdown or even total destruction of the engine.

Description of the invention

The water surplus evacuation system that the invention proposes resolves in a fully satisfactory manner the problem described above, with a solution extraordinarily simple and effective.

For this and more specifically, the invention it consists of mounting on the agitator shaft, at a height level suitable, a small turbine at whose outlet a tube of evacuation that goes directly to the outside of the tank, well through the classic overflow / drain or any other place that It is deemed convenient.

In this way, and since the agitator is is permanently on the move, so will the said turbine, which will normally work in a vacuum, with a consumption almost zero energy, but when the water reaches its level, will be operative, expelling excess water at Exterior.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a representation schematic side elevation and section of a tank beer cooling provided with the evacuation system water surplus that is the subject of this invention.

Figure 2.- Shows one more representation detailed agitation group participating in the figure above, and in which the evacuation system of water of the invention.

Preferred Embodiment of the Invention

In view of the figures outlined and especially of figure 1, it can be seen as the system that is recommended It is applicable to beer cooling vats where set up a wall (1), conveniently thermo-insulated, immediately inside which the evaporator (2) corresponding to a refrigerating unit is located, not shown, responsible for cooling the water (3) that fills the tank and in which the coils (4), (4 '), (4' ') are immersed, corresponding to respective supply lines of different types of beer, such as extra beer, regular beer, non-alcoholic beer, etc., leaving the evaporator coil (2) inserted in an ice mass (5), generated by the casualties temperatures at which said evaporator (2) works, and configures a cylindrical ring that envelops the body of water (3).

As is also conventional and so that the cold uniformly reach the cooling coils of the beer (4), (4 '), (4' '), within the tank a stirrer (6), driven by a motor (7) set immediately above the tank (1), to minimize the occupation of space by the assembly, said motor (7) incorporating a shaft (8) long enough for the stirrer (6) to be placed inside from the tank to the level of the proper tank, settling on said shaft a small turbine (9) that uses the water (3) from the tank to refrigerate the beverage circuits, from the barrel to the tap, to through a driving (10).

Well, according to the invention, about the aforementioned shaft (8) of the agitator motor establishes a new turbine (11), positioned in height on the shaft (8) according to the maximum expected level for water (3) within the tank (1), said turbine (11) being fitted in the housing (12) which relates the lower turbine (9) to the engine support (13) (7), and so that when the water level of the tank (3) reaches its impeller (14), which is permanently moving, when Like the agitator (6), it expels the water outside the tank (1) through a duct or evacuation tube (15) connected to the outlet (16) of said turbine (11).

In this way, the excess of water (3) generated in the tank (1) automatically, safely and effective, taking advantage of the turn that is permanently submitted the shaft (8) of the propeller or agitator (6) of the tank, without Therefore, the classic drain (17) is eliminated by natural overflow.

Claims (1)

1. Device for the evacuation of excess water in beverage cooling tanks, of which they are located between one or more barrels of drink and their corresponding dispensing taps, receiving in their womb the cooling coils of the corresponding circuits, staying in the inside said tank the evaporator of a refrigeration system for cooling the thermal transmission water towards the coils, as well as an agitator with its corresponding motor to homogenize the temperature of the water in the whole tank, characterized in that on the axis (8) that relates the agitator (6) with the motor (7) driving it, incorporates a turbine (11) driven simultaneously with the agitator's own rotation (6), it being provided that said turbine (11) is located high above said shaft (8) in accordance with the maximum level foreseen for the water (3) of thermal transmission inside the tank (1), so that when the water reaches the level of the turbine (11) this causes the automatic expulsion of the excess to the outside of the tank through an evacuation tube (15), conveniently connected on one side to the turbine outlet (11).
