- FIG. 7 shows a sectional diagram of the heating complex.
- the device of the invention relates to the use of at least one heating means (10) positioned outside the container (2).
- This heating means (10) is applied directly against the surface of a wall of the storage container (2) through which heat is transmitted to the oil stored in the container.
- the heating means (10) need not be applied against the entire surface of a wall of the storage container (2). Indeed, the positioning of the heating means (10) against only a portion of the wall may be sufficient.
- the wall of the storage container (2) which is a heat conductor, is then used as a heat-diffusing means for the entire container (2).
- the use of such a device makes it possible to avoid the presence of a particular heating point in favor of heating distributed over a surface or part of a surface.
- heating means (10) are positioned symmetrically on the container. Likewise, in order that the heating and the liquefaction of the oil are more efficient, the heating means (10) used are positioned against the wall of the storage container (2), at the base of the container, for example on the whole length of one side.
- the heating means (10) applied against the wall of the storage device (2) are preferably formed by flexible heating plates (10). These heating plates have in their structure at least one electrical element forming a heating resistor embedded in a flexible material both thermally conductive and electrically insulating which can be silicone or any other polymer having similar properties. This electric heating resistance is powered by at least one power supply means to enable it to provide a power of between 100W and 10000W. According to a preferred embodiment, the heating plates used are self-regulating and fed all or nothing.

- These positioning means (12) are, for example, formed by a rigid positioning plate (12a) pivotable about a hinge (12b) fixed to the container and located at one end of the positioning plate (12a).
- This articulation (12b) forms a fulcrum to allow on the one hand the holding in position of the heating plate (10) and on the other hand its tight and uniform application against the outer wall of the container during the pivoting of the plate positioning device (12a) rigid.
- This rigid plate (12a) has a shape similar to the surface of the wall of the storage container (2) against which the heating plate (10) is applied.
- the rigid positioning plate (12a) is held in a position of application of at least one heating plate (10) against the wall of the container by means of a hook (13) for holding the plate (12a) rigid.
- the hook (13) for holding the rigid positioning plate (12a) in the application position is placed against the edge of the positioning plate (12a) situated at the opposite end of the articulation (12a).
- the edge of the positioning plate (12a) located at the end opposite the hinge (12a) comprises means for pivoting identically two plate locking hooks integral with this means of pivoting. These locking hooks form planar means parallel to the plane of the container faces located on either side of the face against which the heating plate is positioned.
- each hook is traversed by a bore in which is positioned a fastening means integral with the face against which the hook is positioned, so that the hooks remain locked in the hooked position on the storage container (2).
- the rigid positioning plate (12a) and the plate formed by the insulating material (11) have an upper surface or at least equal to the surface of the flexible heating plate (10). The positioning plate (12a) and the plate formed by the insulating material (11) then both follow a same profile, substantially identical to the profile of the wall of the storage container (2) against which the heating plate (10) is applied. ).
- the flexible heating plate (10) is pressed optimally against the wall of the storage container (2).
- the face of the heating plate (10) opposite the tank is pressed by a thermally insulating material (11)
- the heat released by the heating plate (10) is mainly distributed in the direction of the wall of the container. storage (2).
- the positioning plate (12a) is made so as to leave at least a portion of the heating plate (10) accessible so as to allow the passage of electrical supply wires connecting, for example, the heating plate (10) to a electric power device providing electric heating energy.
- insulating material (11) makes it possible, of course, to direct the heat generated by the heating plates (10) to the storage container (2), but also to act as a heat shield by protecting the immediate environment heating means (10) during operation. This protection then allows the positioning of the storage container (2) both in a place isolated from the rest of the restaurant or kitchens, for example buried, as in a place located inside the restaurant, for example at the level of a double partition.
- the storage container (2) comprises on the one hand a conduit allowing its filling (2a) by which the used oils intended to be recycled are injected to be recovered and the other by a conduit for the emptying (2b) of recovered oils .
- the positioning of the filling duct (2a) is positioned on the upper part or on the top of the storage container (2).
- the emptying duct (2b) must have an orifice which, inside the tank, opens in the lower part of the storage container (2) so as to allow optimal emptying of the stored oil.
- the filling duct (2a) which opens into the upper part of the container (2) is located at a lower level with respect to the oils that fill it.
- this difference in level makes it possible on the one hand to reduce a part of the work of the pump (4) and on the other hand to make a saving of surface for the restaurant.
- the storage container (2) wrapped in a heat-insulating envelope, is located in a metal and cement excavation. The emptying of the storage container (2) is then effected by the upper face of the container (2) where opens the drain pipe (2b).
- the collecting body that pumps the stored liquids to a mobile collection tank (7) then connects to the end of the drain duct (2b) to suck up the recovered oils in the storage container (2).
- This connection point may, for example, be disposed remotely with respect to the storage container.
- a branch point (16) remote empties the container (2) without reaching without the collector body is directly in contact therewith.
- Such a connection point may be necessary for practical reasons when, for practical reasons, the container (2) is difficult to access for the collecting organism or is buried, or for hygienic, qualitative or even legislative reasons, when the container is located in an isolated way inside a restaurant.
- the duct (2b) which connects the connection point (16) to the storage container (2) can be buried or placed above ground, for example along the walls of the building or between double partitions or false ceilings.
- the heating means or means (10) applied against one or more walls of the storage container (2) are connected to a control means (6b) of a management device (6) which ensures energizing the heating means (10).
- the storage container (2) is equipped with a plurality of sensors which communicate through one or more electrical connections with a control means (6a) of a management device (6) connected to the control means (6b).
- the tank thus comprises, for example, a temperature sensor and / or a sensor of the filling level of the storage container (2) such as for example a bimetallic sensor making it possible to detect the presence of oil at a height defined by the position of the sensor.
- the measured values are transmitted to the control means (6a) of the management device (6) which by comparison with a stored threshold value determines the activation of the heating device of the storage container (2).
- one or more sensors arranged at the storage container (2) and connected to the control device (6), make it possible to measure the filling rate of the storage container (2). These sensors may for example be bimetallic sensors. These measurements are transmitted to the control means of the management device (6) which, after comparison with a stored threshold value, can trigger an alarm signal or block the flow of the liquid coming from a tank (1) in the process of draining by acting at a pump (4) which ensures the filling of the container (2) and secondly at a discharge valve (17) located at the opening of the filling duct (2a ) in the container (2).
- the oil is transported by means of a mobile tank (5) for the recovery of the oil also called “filtering tank” or “filtering tank”.
- This tray (5) comprises, for example, one or more superposed oil filters whose mesh is decreasing, and positioned above a container whose capacity is sufficient to receive and contain the oil of one or more tanks (1) frying appliances.
- the mobile container (5) is, for example, brought under the tank (1) of a frying apparatus to collect the oil it contains, through an opening at the base of the tank, the oil s' then flows by gravity into the tray (5).
- the mobile tank (5) can then be used to empty several successive tanks (1) of the oil they contain, then this mobile tank (5) is fed to a pump (4) intended to suck the oil previously recovered for transferring it via a feed duct (2a) into the oil storage container (2).
- Baccalaureat mobile (5), to be drained may include for example a conduit opening into the bottom or near the bottom of the tray (5) and by which the pump (4) sucks the oil to be recycled.
- the filling duct (2a) of the storage container (2) is connected to the various tanks (1) for using the restaurant's edible oils via one or more ducts (3) capable of forming a network.
- the flow of liquids through these pipes (3) is facilitated on the one hand by the presence of an electric pump (4) which ensures the junction between the filling duct and on the other by the integration of less a heating complex positioned in the network of pipes for the transfer of liquids.
- the tanks of the fryers (1) are emptied while the used oil is still at high temperature.
- the edible oil is heated to about 180 ° C, and although the oils are generally allowed to cool before the vats (1) fried are drained, it is often the case that these oils are still very hot .
- the pipes and the heating complexes (3) are made around a skeleton (3b) corrugated stainless steel which gives the conduit a certain flexibility and thus facilitates its assembly around the different branches of machines that can be encountered in a kitchen and hard to reach spaces (false ceiling, etc .).
- This skeleton (3b) of steel-stainless steel pipe is covered on its inner face with a polymer (3a) thermally and chemically resistant.
- the polymer used is PTFE (polytetrafluoroethylene).
- the skeleton (3b) of the conduit is covered on its outer face with a braided steel sheath (3c).
- a heat-insulating shell (3e) generally made of insulating foam, is used to surround the entire duct. manifold.
- the solidification temperature of used edible oils is variable according to its composition, the amount of food residue found there, etc.
- This solidification temperature is generally close to or greater than the temperature or temperature of the collecting ducts. It can therefore happen, if the emptying of the tank (1) of use is carried out while the temperature of the oil is close to its solidification temperature, that the oil in flow in the pipe solidifies and the mouth.
- the manifold duct network integrates one or more heating complexes which consist of a pipe with which is associated a heating means (3d).
- This heating means (3d) made from a heating cable (3d) whose temperature is self-regulating, is connected to a control means (6b), itself integrated in a management device (6).
- the heating cable is thus positioned along the collection duct, on one or more portions of the collection network, between the steel braided sheath and the foam protective shell.
- This heating cable runs along the conduit against only one side of the conduit, but the braided sheath (3c) made of steel ensures the conduction and diffusion of the heating over the entire periphery of the conduit.
- This heating cable formed by a ribbon when it is activated by the control means (6b), makes it possible to obtain a heating complex (3) whose temperature is self-regulating above the solidification temperature of the flowing liquids.
- Such a device eliminates temperature regulation involving one or more heat sensors along the pipe. Nevertheless, at least one sensor may be used to monitor the activity of the heating complex (3), this sensor being connected to the control means (6a).
- heating complexes (3) can be positioned, they can either be each independently connected to the control means (6b) which ensures respective activation, or be interconnected, one being then in relationship with the control means (6b) so that the activation is common for all the heating complexes (3) present on the collection network.
- a similar heating complex is formed on the one hand at the filling duct (2a) of the storage container (2) and on the other hand at the drain duct (2b), thus avoiding their respective obstruction by solidified oil residues.
- the tanks (1) for using the liquids are emptied by suction of the used liquids by means of a pump (4) positioned on the collection network formed by the various pipes (3) which ensures their transfer to the duct. supply (2a) of the storage container (2).
- the activation of this pump (4) is managed by the control means (6b) of the management device (6).
- the electric pump (4) has two bypass valves (14) positioned close upstream and downstream of the electric pump. These valves (14) are activated manually and enable the filling oil to be diverted to a duct incorporating a manually activated pump (4b2) arranged in parallel with the electric pump (4).
- the manually activated pump (4b1) forms a supply means for the independent storage container connected directly to the upper part of a wall of the storage container.
- the liquids are filtered through at least one filter tank (5) which has one or more screens with more or less large meshes.
- the filter tank (5) is mounted on a wheel so as to be able to be moved by the user and has dimensions allowing to be positioned under the outlet of the used liquid from a tank (1) for use to be drained.
- the filtering is then carried out by suction and / or gravitation of the used liquids through successive sieves arranged vertically and kept apart between them by intercalating means. The different residues, food or otherwise, which can remain after several cooking cycles are eliminated.
- three superimposed sieves are used, the meshes of which are successively 5 mm, 2 mm and then 1 mm and make it possible respectively to retain the large food residues, the breadcrumbs and then the starch suspended in the liquids.
- This aims to recover only used liquids for the sake of recovery and to limit the risk of clogging of the collecting ducts (3).
- the filter box (5) used it is easily removable by the user to allow its maintenance and cleaning.
- the filter tank (5) is provided with a lid which on the one hand has an orifice to allow the liquid-handling tank (1) to be emptied into the tank (5) by limiting the splashing and secondly prevent an accidental release of contaminants when the tray (5) is not used.
- a draining of the filter tank (5) can be achieved by moving it near the hand pump (4b). ).
- the bottom of the tanks (1) of frying generally has an opening through which the draining takes place. This opening communicates with the outside of the tank (1) at a valve which must be actuated so that the emptying can take place.
- the tank may have an evacuation duct that runs along the edge of the tank (1) and a first end of which is open at a boss located near the bottom of the tank (1), the second end of the duct leading to the outside of the tank (1). The distance separating the first end of the pipe from the bottom of the tank (1) must allow suction of almost all the oil present in the tank (1).
- one or more different sieves or filters are positioned in the bottom of the tank above the first end of the exhaust duct so that the liquid sucked does not recover food residues.
- the collecting duct (3) can form a more or less large network integrating a pump (4) and one end of which is connected to the filling duct (2a) of the storage container (2), the other ends being connected either to the emptying opening of the tanks (1) for the use of liquids, or at the outlet of the filtration tanks (5) when the tanks (1) pour into a respective (or common) filtration tank (5) during emptying.
- the collector pipe (3) is fixed to the outlet of the filtration tank (5) by means of a connector (9) that is angled, sealed and orientable.
- This connector (9) has a first end secured to the collector duct (3) at one end of the network, the second end has an axis located at an angle substantially perpendicular to the axis of the first end.
- This second end is circular and has an internal diameter identical to or substantially less than the internal diameter of the outlet of the tray (5) of filtration to which it connects. Furthermore, the inner face of the outlet of the filtration tank (5) has a tapping intended to interact with a thread located on the outer face of the second end of the connector (9). In addition, to improve the sealing of the fastener, one or more O-rings are positioned in respective annular grooves which surround the outer face of the second end of the connector. Annular grooves, located on the inner face of the outlet of the filter tank (5) are intended to receive a respective O-ring once the connector (9) placed on the liquid outlet of the tray (5) filtration.
- the connector (9) once fixed allows to orient the flow of used liquid in a plane perpendicular to the output axis during the emptying and thus to overcome the spatial constraints due to the positioning of the tray (5) filtration under the tank (1) to empty in small spaces.
- the use of a fastening by a thread / tapping system participates with the presence of O-rings to seal the connection while allowing orientation of the connector.
- An attachment of the connector (9) can be similarly performed directly on a tank outlet (1).
- the tubular portion forming the outlet of the bent filtration tank (5) is formed of two successive solid elbows.
- This tubular portion which makes the outlet of the filtration tank (5) shows a first end open towards the outside and at which the connector is positioned and a second end open to the filtration tank (5) to which it is secured. .
- the double bending is carried out so that the respective axes of the first and second ends of the outlet of the tray (5) are arranged parallel, substantially vertically, and oriented on the same side, upwards, so that the second end is fixed to the underside of the filter tank (5).
- the outlet of the filtration tank (5) then has a tube with a shape similar to that of a "U".
- the means for emptying the tank (1) of use or the tank (5) filtering are positioned under the tank (1), and access to these different elements requires the opening of a door located at a distance from the ground and which closes the space under the tank (1).
- the tubular portion forming the outlet of the filtration tank (5) is then made so that the upper edge of the first end of the outlet of the filtration tank (5) is positioned substantially below a horizontal plane which passes through the lower edge of the door and thus leaves the space under the tank (1) beyond the door by the space between the door and the floor.
- the door remains open during the handling of the tanks (1) and allows the person handling the device during the emptying to avoid forgetting to leave the manifold (3) connected to the outlet of the tank (5). ) or the tank outlet (1), thus avoiding a vacuum operation of the pumping system.
- the portion of the bent tube forming the outlet of the filtration tank (5) or of the tank (1) located between the second end attached to the tank (5) or the tank (1) and the elbow the outlet which is closest to the second end forms a junction forming a rotating connection.
- This rotating connection allows the rotation of the outlet of the tank (5) along the axis of the second end of the outlet of the tank (5), and thus not to exceed this tank outlet (1) or tank (5). ) filtration out of the space under the tank when the manipulator does not drain.
- the connector (9) bent is associated with the end of the duct (3) collector with a rotating connection.
- a feature of the connector (9) is that it is associated with a closure means of the collector duct (3).
- the sealing means hermetically blocks the end of the collecting duct (3), likewise a closure means blocks the flow in the output of the filter box (5). This closure disappears only once the connector (9) attached to the outlet of the tray (5).
- shutter means that can be used is the push-pull system.
- This ball (9d) is housed in a cavity (9a) which extends on one side (9b) to the collector pipe (3) and which on the other side has the orifice (9c) of the connector (9).
- the ball (9d) is mounted on a spring (9e) which pushes the ball (9d) against the orifice (9c) of the connector (9) and thus obstructs the orifice (9c) of the connector (9).
- a cavity (5a) Between the orifice (5c) of the first end of the outlet of the tank (5) and the bend of the outlet of the tank (5) closest to this end, is disposed a cavity (5a).
- This cavity (5a) extends on one side (5b) towards the bend of the outlet of the tray (5) and on the other side presents a opening (5c) towards the first end of the outlet of the tray (5).
- a closure valve (5d) mounted on a spring (5e) and which is pushed against the opening (5c) towards the first end of the outlet of the tray (5) and thus obstructs this exit.
- the shut-off valve (5d) has a nipple (5f) on its outer face which leaves the cavity (5a) to overflow at the first end of the outlet of the tray (5) in the insertion zone of the orifice (9c) of the connector (9).
- the connection of the second end of the connector to the outlet of the filtering tank thus makes the nipple (5f) of the shut-off valve (5d) come into contact with the sealing ball (9d). This contact pushes the valve (5d) and the ball (9d), causing the ball (9d) and the valve (5d) to move away from their respective obstructed apertures (5c and 9c), thus allowing the passage of the recovered liquid.
- the connector (9) bent, sealed and orientable is positionable at the outlet of the tank (1).
- the oil is sucked by means of a pump rod (19).
- This pump rod (19) manipulated by a user, has on the one hand a rigid tubular structure intended to be introduced into the tanks (1) to be drained, and on the other hand a flexible tubular structure connected at its end to a conduit connected to the pump (4) associated with the filling duct (2a) of the container (2) for storage, thus allowing the extraction of used oils.
- a handle provided with a protective device makes it possible to limit the risk of burns when the rod (19) is manipulated by the user.
- the cane (19) is provided with a filter screen at its end.
- the pump rod (19) includes a non-return valve.
- This non-return valve housed in a chamber of the structure of the rod (19) traversed by the flow of oil sucked by the rod (19) comprises a movable means mounted on a spring. Since the moving means is wider than the oil inlet orifice in the chamber, the spring thus pushes the moving means against the flow of oil in suction to obstruct the arrival of oil. The arrival of oil in the chamber is thus obstructed when the suction is below a critical flow, and released when it is greater than the same critical flow.
- each of the tanks (1) has, in the vicinity, a conduit (3) clean connected to the entire collector network.
- the manipulator connects the end of the tubular flexible structure of the rod to the conduit (3) clean of the tank (1) which is drained.
- the connection of the flexible tubular structure on the duct (3) for draining the collecting network located near the tank (1) is carried out in a manner similar to the connection of the collector duct (3) to the connector (9) explained above. .
- the management device (6) automatically synchronizes the activities of different elements of the system that have connected to it.
- the management device (6) actuates, by means of a control means (6b) connected to a strong current network, powering up of the pump (4), of the heating complex which surrounds the various collector ducts (3) of the network. of pipelines and the storage container (2).
- the control device (6) via a control means (6a) connected to a weak current network connected to the various sensors of the storage container (2), monitors the operation of the system on which it can intervene by blocking its operation.
- the management device (6) comprises one or more communication means on the one hand with elements of the recovery system and on the other hand with management interfaces (8) for the user, these interfaces (8) being able to be formed by a fixed interface (8a) to the management device (6) or remotely and remotely (8b). These interfaces (8) with the user can for example take the form of a touch screen.
- the management device (6) is connected to a remote management element (18) allowing for example telephone or internet communications via a communication network which can be for example of the GSM or Internet type. These communications can be made for example with the agency responsible for emptying the storage container (2), so that the achievement of a certain level of filling causes the sending of a signal to the body responsible for the emptying.
- the management device (6) also comprises a signal production program. These signals can be preprogrammed, either written in the form of simple messages of the SMS type, or written in the form of more complex e-mail messages.
- the management device (6) is also connected to an alarm device to prevent the user or a speaker in case of a problem or accident.
- the management device (6) further comprises one or more storage means for storing one or more preprogrammed threshold values, as well as at least one program for managing the operation of the system. Access to the different storage means is allowed from at least one of the user interfaces to allow on the one hand the modification of the stored threshold values and on the other hand the modification of the programs.
- the control device also comprises a timer so that the activation of the control device (6) activates the automation of the system and makes it possible to manage the activation and the operation of the various elements of the system only when their activity is necessary during time slots for emptying the tanks (1) of use.
