IN THE PUMP BODY ARE PROVIDED AN INPUT PORT 4, THROUGH WHICH THE WATER AND DEPOSITS ARE ASPIRED, AND ONE OR MORE OUTPUT ORIFICES 5, ALLOWING THE DRAIN OF WATER AND DEPOSITS. THE ADVANTAGE OF THE PRESENT INVENTION IS THAT IT ALLOWS A SUFFICIENT AGITATION EFFECT TO CAUSE THE RAPID FLOATING OF THE DEPOSITS CONTAINED IN THE WATER.

Description

The present invention relates to a fluid agitator assembly for

  agitation of the liquid to allow the flotation of the deposits of a liquid in a water storage tank containing compacted sludge not yet hardened or lime etc, or water such as

  wastewater containing foul stuffs.

  The disadvantage of the conventional fluid agitator

  However, it is difficult to obtain sufficient flotation of the deposits because the stirring force produced does not propagate sufficiently and uniformly from the periphery of the body of an agitator to the entire bottom of the liquid reservoir. , so the force is

  transformed into a current directed upwards.

  The present invention has been developed to provide a solution to the above problem and relates to an improved fluid agitator assembly having sufficient agitation effect to achieve flotation.

fast and efficient deposits.

  In accordance with one aspect of the present invention, the fluid agitator assembly includes a submerged motor with a downwardly extending output shaft and to which an impeller is attached, and a pump body at the bottom of the engine to surround the impeller and having an inlet at its bottom and one or

  several outlets on its circumferential wall

  the improvement being that the position

  and the number of orifices are variable.

  According to another aspect of the present invention, the fluid agitator assembly comprises a submerged motor with an output shaft to which an impeller is attached, and a pump body at the bottom of the motor to surround the impeller and having a inlet port at its lower part and one or more discharge holes on its circumferential wall, the improvement being that the position and the number of orifices are variable, in that the end of the output shaft is traversed the inlet port and in that a

  stirring blade is attached to this extended part.

  The invention will be better understood, and other purposes, features, details and advantages thereof

  will appear more clearly during the description

  explanatory document which will follow with reference to the accompanying schematic drawings given solely by way of example illustrating several embodiments of the invention and in which: - Figure 1 is a front view of an embodiment of the present invention; ; FIG. 2 is a front view of another embodiment of the present invention; Fig. 3 is a vertical section showing the essential parts of the embodiment of the present invention illustrated in Fig. 2; Figures 4,5,6 and 7 are bottom views of the embodiments of the present invention, each with a different pump body; and FIG. 8 is a front view of an embodiment of the present invention for which

does not use a perforated filter.

  FIG. 1 shows the equipment according to the first embodiment in which an immersed motor 2 of the fully watertight type having an output shaft 3 on which an impeller 1 is fixed, is put in water, the output shaft 3 being extended downward. A pump body 6 is mounted below the motor 2, so that it concentrically surrounds the output shaft 3 and the impeller 1. The pump body 6 has in the center of its lower part an orifice of entry 4 and on his

  circumferential wall one or more discharge orifices

  5, as illustrated in more detail in FIGS. 4 to 7.

  Below the pump body 6 is a perforated filter 7 having a plurality of openings to a desired diameter and attached to the lower portion of the pump body. The filter is then supported on the melting of the water tank by a

chassis 10.

  In the second embodiment of the present invention illustrated in FIGS. 2 and 3, the lower part of the output shaft 3 of the immersed motor 2 is extended downwards through the inlet orifice 4 of the pump body 6 and through a through hole 8 formed in the filter 7, and a stirring blade 9 is attached to the end

of the output shaft 3.

  An injection nozzle 12 shown in a fantasy line is coupled to each of the discharge ports 5 in the pump body 6 by a flange coupling as shown in FIGS. 1 and 2. The injection nozzle 12 is provided to freely modify its injection direction by changing its angular position, ar rqDpt at the bb-crnmnoe surface of b h-Me of the evacuation vessel 5. A hose 13 of a desired length can be mounted on the extension of the nozzle 12 Alternatively, the hose can replace the nozzle 12. In each case, the hose 13 makes a snake-like movement due to the force.

  contrary to water, which reinforces the statistical movement

  tick of the injection direction of the nozzle 12.

  An explanation of the operation of the fluid agitator assembly according to the present invention will

now to be given.

  With regard to the first embodiment of the present invention for which no stirring blade is used, the stirring assembly is immersed in water containing deposits in a tank and is placed in the bottom. of the tank. Then the engine

  immersed 2 is started. Engine 2 works

  It rotates the impeller 1 fixed on the output shaft 3 of the motor, so that the water around the perforated filter 7 and the displacements that have accumulated underneath are necessarily sucked in. pump body 6 through the openings of the filter 7 and the inlet port 4 of the pump body 6. The water and deposits sucked into the pump body 6 are then discharged through the discharge orifice 5 and the nozzle

  12 and / or the hose 13 in a jet in the tank in a predetermined direction (for example, normal or parallel direction at the bottom of the tank, or upwards) and thereby, water and deposits of the tank are subjected to the strong agitation of the jet of water. With regard to the second embodiment of the present invention, for which a stirring blade 9 is used, the stirring assembly operates substantially

  in the same way as for the first embodiment.

  However, unlike the first embodiment, the rotation of the output shaft 3 of the motor 2 is also caused by the stirring blade 9 at its

  end, but in such a way that it turns with the impulse

  1. Such a design makes the rotation of the output shaft 3 can cause a much greater agitation force than in the first embodiment. That is, when the stirring blade 9 rotates in the same time as the impeller 1, the water beneath the perforated filter 7 is stuffed into the blade 9, and is The energy contained in this moving water causes sufficient agitation of the deposits located at the bottom of the tank, thereby creating a turbulent flow through which the deposits are suspended in water. This turbulent flow is guided upwards and radially by the opposite force

  from the wall of the bottom and goes to the perforated filter 7.

  The turbulent flow is then vigorously sucked into the pump body 6 through the orifices of the perforated filter 7 and the inlet port 8 by the rotation of the impeller 1 and is jetted into the reservoir through the discharge port 5 and the injection nozzle 12 and / or the hose 13, the reservoir water being thereby msme

strongly agitated.

  In the first and second embodiments above, the direction and number of the injection nozzles Q can be adjusted at will by changing the angular position relative to the circumference of the flange of the discharge port 5. This makes possible either a uniform agitation over the entire bottom of the tank, or local agitation depending on the only part of the bottom of the tank where accumulates a considerable amount of deposits. In addition the hose 13 allows a statistical variation in the direction of injection of the water discharged into the tank. This ensures fast, strong and uniform flotation of the accumulated deposits not only on the bottom part of the tank located below the agitator assembly, but also on the entire bottom and prevents the

  redeposition of particles suspended in water.

  Of course, the invention is not limited to the embodiments described and shown which have been given by way of example. In particular, it includes all the means constituting technical equivalents of the means described and their combinations if they are executed according to its spirit and implemented.

  in the context of protection as claimed.
