Definitions

  • the present invention relates to a device which allows the transport of the marc of oil, through a pipe or a similar means, comprising an element in the form of a double-acting pump whose inputs and outputs have a valve which controls the emission of product through the corresponding conduit.
  • the marc of oil is a product which contains a paste with approximately 57% of residual grinding liquid, 37% of solid matter and 6% of still usable oil; There are present the skins and the nuclei of the olives after the first press, which explains the existence of large particle size bodies. It is a very corrosive product for the materials that make up the entire installation and that is why special care must be taken in the design and construction of this type of pump.
  • the device recommended here comprises a double-acting pump body which is formed of two bodies which respectively have one or two product inlet conduits and one or two other outlet conduits, on which are identical identical valves, but reversed. These two bodies are united through a cylinder in which a piston alternately moves, actuated by conventional external means, which alternately creates in each pumping body a depression which tends to open the inlet valve providing access for the product to inside the pumping body, while in the opposite body, the effect is opposite and tends to close the inlet valve.
  • Each of these pumping bodies has a configuration according to a cube in which is established on one of its sides, the union with the control cylinder, at least four of its sides remaining free and with access openings for coupling to any of them the inlet and outlet valves, while the others close hermetically, the installation can thus adopt any configuration, since for example, the inlet can be located on the upper side and the outlet on the lower side or laterally, and vice versa.
  • the inlet and outlet valves fixed to these bodies are similar and are placed in opposite directions, so that they create continuity in the line or means of transfer of the marc of oil.
  • These valves have an elongated body which defines an inner conduit, which closes on the side of the bases in two equal connection plates so as to allow their installation and fixing in the appropriate operating direction, depending on whether they constitute the valve d entry or exit of the pumping body.
  • Each of these valves has a conical control piston which moves axially since it is mounted on a rod or axis whose path is made on two extreme supports located at the mouths of the pump and which define a central support for the path of this rod.
  • This valve has a spring which tends to incide on the conical part of this rod to an internal mouth present in the pump, thus tending to keep the valve closed as long as there is no vacuum inside causing displacement of this spring and therefore the passage of product, a question which is carried out in the direction which goes from the mouth through which the apex of the obturator piston appears towards the outlet situated on the opposite side; thus, when the valve is placed at the inlet of the pumping body, the top of this piston is located towards the outside, that is to say on the side opposite to that coupled to the pumping body, while when it configures the outlet valve, this top is placed towards the pumping body directly, creating a conduit in which it is necessary to control the action of the spring of the inlet first and then of the outlet to provide
  • the device for transferring oil grounds represented in general terms in FIG. 1, comprises two pumping bodies (1) which are joined together by a cylinder (2), in which moves a piston (3) which is joined to an actuating piston (4) which receives externally a connecting rod (7) coupled to an eccentric (8) which rotates by virtue of a motor (9), so that with the evolutions of the motor we obtain the longitudinal displacement in the alternating directions of the piston (3) and as will be seen later, the transfer of product into one of the bodies (1), both acting also alternately.
  • the bodies (1) have, in addition to the union with the intermediate cylinder (2), an inlet pipe and another outlet, in which are located control valves (5), both identical and placed in opposite directions with respect to the central body (1). Both the entry and exit to these bodies (1) can be effected through two conduits.
  • These pumping bodies (1) shown in more detail in FIG. 2, preferably have a cubic configuration in which an internal drain has been produced and several accesses on all sides of it, so that, except the side on which it is united to the cylinder (2), the others remain operative to constitute any of them the inlet and / or outlet conduits, with a view to which, it has on all sides a uniform orifice and corresponding holes for fixing by screwed means or the like.
  • the inlet can be placed on the upper side, or on any of the lateral sides and the outlet, on the bottom side and also on any of the side sides. Except for the sides which constitute the inlet and the outlet, the others are hermetically closed by means of a solid plate fixed at the same points as the corresponding valve.
  • valves which control the entry and exit of the pumping bodies (1) have been shown in detail in Figure (3) and as already indicated, both are the same and are placed opposite a on the other from the pumping body (1) located in the middle.
  • Each of these valves (5) comprises a general conduit which goes from a product inlet (18) to the outlet (19), showing on two sides, bases (10) having an identical configuration and fixing points (11) on the corresponding pump body (1).
  • the valve duct (5) has a mouth (12) which defines inside a seat base for a conical piston (13) which acts against this mouth (12), when a spring (14) is interposed in the concavity of the latter, colliding with an external tie rod (16).
  • This piston (13) is mounted on a rod (14) which in turn can move axially and is coupled at both ends to the supports (15) and (16), fixed on the sides of the main pipe of the pump and definitory an axis on which this rod (14) moves.
  • this device which is obtained by means of a motor (9) which moves the piston (3) from right to left, causes in one of the pumping bodies a depression which tends to open the valve input, constituted in the figures by that shown in the upper zone, in order to overcome the resistance of the spring (14), while on the opposite side, the increase in pressure tends to close this inlet valve while the outlet valve, which is located in the opposite position, tends to open it by discharging the product inside.
  • the piston (3) moves in the opposite direction, the action on the corresponding pumping body (1) is reversed and thus, the one which filled, pushes its contents outwards, while the opposite which s 'was emptied at the previous moment, introduced product through the inlet valve. In this way, constant pumping is achieved, which causes the product to exit through any of the pumping bodies (1), the outlets of which can be connected to a single conduit, in the same way as the inlets can be.
