Definitions

  • the invention relates to an intermediate tank assembly for domestic wastewater recycling equipment which provides improved advantageous features for its intended function, which features involving an improvement in the current state of the art in this field will be described in detail below.
  • the object of the invention is an intermediate tank intended for forming part of a domestic wastewater recycling equipment or system, specifically applicable for a disposition of said type such as that described in patent number P200101084 belonging to the present applicant which, being configured as a compact assembly that includes the elements intended for collecting and delivering the water to be recycled in said equipment, has a series of structural improvements with respect to that already known considerably improving system efficiency.
  • the field of application of the present invention is encompassed within the technical field of the industry dedicated to the manufacture of recycling elements, apparatus and devices, particularly those intended for recycling water.
  • each tank incorporates a buoy in the intermediate tank responsible for ordering the operation or the shutdown of the electric pump, and a buoy in the storage tank responsible for achieving a continuous service and cleaning thereof.
  • the intermediate tank assembly for domestic wastewater recycling equipment proposed by the present invention is configured as a novelty within its field of application because the objectives mentioned above are satisfactorily achieved in a specific manner in light of its implementation, the characterizing details distinguishing it being suitably listed in the final claims accompanying the present specification.
  • the invention proposes a tank intended for forming part of a domestic wastewater recycling equipment of the type incorporating a receiving tank for receiving the water coming from a washer or the like, from which said water is moved upwards to a second storage tank through the corresponding pipes and delivery means, and the water is subsequently channeled by gravity to toilet cisterns.
  • Said tank is configured as a compact assembly that includes the elements intended for collecting and delivering the water to be recycled and the construction of which is of stainless steel, using this very material for said tank itself, for its supporting and anchoring base as well as for the water inlet and outlet pipes, and the dimensions of which, in relation with the known systems, specifically with respect to that described in the patent mentioned above as the prior art, have been reduced by 50%, and said tank has the particularity of incorporating inside the receptacle forming said tank itself a cylindrical filter also made of stainless steel, having a diameter of about 80 mm and a length corresponding to the tank measurements since it spans the entire width thereof.
  • a filtering mesh makes up approximately 2/3 of the length of said filter, while the remaining 1/3 is occupied by a chamber where the water to be recycled coming from the washer is poured therein to be filtered from the inside to the outside.
  • the tank has an overflow outlet which is in turn connected with the main overflow, pouring directly into a sewer.
  • the location and housing of said filter in the booster tank is determined by the existence of a male thread welded to said tank having a diameter of 80 mm, as has already been mentioned, to allow removing and housing the filter in question and subsequently washing it.
  • said threaded lid of the filter is completed with a female cover which can be screwed on manually.
  • the previously mentioned chamber of the filter is also responsible for advantageously eliminating noise of any kind produced by water when it is poured into the tank, thus achieving quiet equipment.
  • the tank has an additional pipe provided with a shutoff cock, the function of which is to allow removing the water stored in the tank at will and to thus facilitate cleaning the filter without any type of water spillage or seepage, for which dry filter cleaning is performed.
  • both the circuit breaker for the pumper unit and the level relay for the level probes will be deposited in said box, being coupled next to the pumper unit in the same supporting base in which it is fixed.
  • Figures 1 and 2 shows the respective side-front perspective views taken from opposite sides of an embodiment of the intermediate tank assembly object of the invention, the general external configuration and the main parts and elements that it comprises being seen therein.
  • Figure 3 shows a perspective view of the upper part of the example of the intermediate tank assembly according to the invention shown in the preceding figures, which has been depicted as being opened on top in order to allow observing the elements internally incorporated by the receptacle of said tank itself, specifically the filter housed therein.
  • the assembly tank in question applicable as has already been reiterated in a domestic wastewater recycling equipment such as an intermediate receiving tank for receiving the water coming from a washer or the like, and from which the water moves upwards to a storage tank through the corresponding pipes and by means of forced delivery means for channeling it by gravity to the toilet cisterns, is configured as a compact assembly (1) that includes the elements intended for collecting and delivering the water to be recycled, comprising a small-sized stainless steel receptacle forming said receiving tank (2) itself, to which there are coupled at least one inlet pipe (3) with its corresponding shutoff cock (4), and one outlet pipe (5), both also made of stainless steel, being fixed on a supporting base (6) also made of stainless steel, with the particularity that said tank (2) internally incorporates a cylindrical filter (7), also made of stainless steel, of about 80 mm in diameter the length of which spans the entire width of the mentioned receptacle.
  • a mesh (8) makes up approximately 2/3 of the length of said cylindrical filter (7), while the remaining 1/3 is occupied by a chamber (9) where the inlet pipe (3) pours the water to be recycled therein to be filtered from the inside to the outside by means of the corresponding internal conduit (10).
  • This cylindrical filter (7) is coupled at one of its ends to a male thread welded to the tank (2) in a hole made therein for such purpose, thus allow its extraction for its subsequent washing, which is completed with a cover (11) having a female thread which is operated manually.
  • said filter is connected to an overflow outlet (12) which is in turn connected with the main overflow (13) of the tank (2), pouring directly into the sewer through a drainage line (20) provided for such purpose, and which is connected to the shutoff cock (4).
  • the tank (2) has on the bottom an inclined lower base (14), there being an additional drainage pipe (15) with a shutoff cock (16) therein for removing the water stored in said tank (2) and facilitating the dry cleaning of the filter (7).
  • a pumper unit (17) as a means for moving the water upwards to the storage tank of the equipment (not depicted) is contemplated at the same time and associated with the assembly (1) by means of the incorporation thereof in the supporting base (6) provided in the lower part of the tank (2).
  • the receptacle forming the tank (2) internally incorporates two electrical contact probes (18) intended for measuring the maximum and minimum level of water, transmitting the electric contact order for the operation or shutdown of the pumper unit (17).
