Definitions

• the present invention relates to a filter external to a tank, in particular to an aquarium.
• Aquariums are generally equipped with an air pump which promotes the settling of micro-particles, as well as possibly a carbon dioxide generator promoting the growth of the plants contained in the aquarium.
• These bubbles are sucked in by the water pump, which circulates the water in the filter, and are in the relaxed position in the filter.
• This air or this gas lowers the water level and can put the blades of the turbine out of the water causing a cavitation phenomenon, then stopping the suction and putting the installation in conditions of defusing.
• the air trapped in the tank tends to come out, and tends to follow the easiest path. If the air passes to the suction side, the siphoning conditions will be eliminated and the filter will not be able to restart.
• the object of the invention is to provide an external filter to a tank which can operate without additional noise from the cavitation of the pump due to the presence of an emulsion of water and air, which can restart without problem. and without risk of defusing after a stop due to a power failure or a voluntary interruption resulting, for example, from cleaning the filter.
• the filter which it relates to of the type comprising a tank closed in leaktight manner by a cover, the tank containing at least one basket serving to house the filtering components and comprising an upper wall bearing with sealing in the central part. of the cover and allowing communication with this central part which contains a water circulation pump, the water being brought through the cover by a tube passing through it, descending into the tank outside the basket, penetrating in it by its bottom, crossing the basket from bottom to top with passage over the filtering components, and leaving the basket at the top and in the central part of it to be sucked by the pump and discharged into a tube passing through the cover to the delivery pipe to the tank, includes means for automatically evacuating the air from the side of the water delivery.
• the air possibly contained in the filter being automatically evacuated from the discharge side, the suction side remains charged, so that the pump operates normally, without cavitation and without risk of priming, as soon as it is switched on.
• the upper wall of the basket comprises a crown delimiting an opening for the outlet of water, and intended to come to bear in a groove of the cover with sealing by a seal
• the crown comprises at least one radial opening.
• the filter according to the invention comprising a suction outlet arranged in the inner wall of the cover, and comprising a cylindrical part which is mounted in a crown secured to the cover and the central part of which comprises a chimney suction, _ the crown has at least one through slot disposed opposite an opening of the cylindrical part, when the latter is in the mounted position in the crown.
• the cylindrical part has a bottom connecting its peripheral part to the suction chimney, in which is formed at least one hole. It is thus possible to recover, at the periphery of the suction chimney, the air being in the upper part, and to evacuate this air parallel to the suction chimney to avoid its accumulation in this area with the disadvantages that this generates.
• the filter according to the invention in which the delivery tube comprises a substantially horizontal part at the outlet of the pump, oriented from the inside towards the outside, extended by a vertical part passing through the cover, a orifice forming an air intake communicating with the interior of the tank opens into the upper part of the horizontal tube, at its junction with the vertical tube.
• the water intake manifold inside the tank protrudes from the cover towards the inside of the tank, in order to To dive in the water. In this case, as soon as the pump stops, the air escapes through the orifice forming an air intake communicating with the discharge pipe, the air being unable to escape from the side of the intake pipe.
• the filter shown in the drawing comprises a tank 2, on which a cover 3 is tightly fixed.
• the tank contains a basket 4, inside which are arranged filter elements designated by the general reference 5.
• This basket delimits with the tank a peripheral space 6 allowing the movement of water from top to bottom, the water then passing through the bottom 7 of the basket which is perforated, passing through the filter elements 5 from bottom to top, and leaving through the central part 8 of the cover 9 of the basket, this perforated central part being delimited by a crown 10 bearing in a groove in the cover, with the interposition of a seal 1 2.
• the cover 3 is crossed by a tube 1 3 entering the water, which opens to the outside of the crown 10 of the basket, the end 14 of the tubing, on the inside of the filter protruding from the cover so as to be immersed inside the liquid 1 5.
• the central part of the cover Circle contains a motor intended to suck up the water, the tub 1 6 of which is shown in the drawing.
• the sucked water is discharged by a section of horizontal tubing 17, extending by a section of vertical tubing 18 which passes through the cover.
• the section 1 7 opens laterally, this for reasons of molding of synthetic material, the opening end of the tube part 1 7 being closed by a plug 19.
• the turbine 1 6 is disposed a crown 20 projecting from the cover towards the inside of the filter, this ring 20 serving to house a cylindrical part 22, part of which takes support against the crown 20, and is extended by a bottom 23 which carries a central suction chimney 24.
• these various members include orifices or slots allowing the passage of residual air on the discharge side.
• This is in particular an opening 25 formed in the crown 10 projecting from the upper part of the basket, openings 26, 27 formed respectively in the crown 20 and in the cylindrical part 22, the openings 26, 27 being in coincidence and two in number.
