Definitions

  • the present invention concerns a procedure in collecting comestible liquids, particularly in milk collection from milk producers effected with the air of tank lorries, in said procedure the comestible liquid being conducted through a suction tube to an air separator, where the air present in the comestible liquid is separ­ated, and from said air separator to a metering means which meters the quantity of comestible liquid that is caused to flow through.
  • the invention also concerns a means for implementing the procedure.
  • the object of the present invention is to provide a procedure and means which enable comestible liquids to be conducted from the air, separation tank to the volumetric metering device in a simple, yet reliable, manner.
  • One of the aims of the invention is a procedure and means in which separation of air from the comestible liquid, e.g. from milk, can be implemented in a simple yet reliable manner, and in which starting and termination of metering can be accurately performed.
  • the procedure of the invention is mainly characterized in that the comestible liquid is caused to flow from the air separator to the metering device along a flow line without any pump means inserted in said flow line, and that the flow of comestible liquid in said flow line is controlled with the aid of a valve means inserted in a manner known in itself in the art in said flow line, the level of the comestible liquid in the air separation tank having been arranged to control said valve means.
  • the means of the invention is mainly characterized in that the means has been disposed to cause flow of the comestible liquid from the air separator to the volumetric metering device along a flow line without any pump means inserted in said flow line, and that the flow of comestible liquid in said flow line is controlled with the aid of a valve means inserted in a manner known in itself in the art in said flow line, the level of the comestible liquid in the air separation tank being arranged to control said valve means.
  • a tank in which the comestible liquid is collected is collected.
  • the tank 1 is advan­tageously a vacuum tank in which vacuum is produced with the aid of a vacuum pump 2a.
  • the punp 2a has been disposed to produce vacuum along the passage 2b.
  • the tank 1 may advantageously be bipartite, comprising parts 1a and 1b, in which different liquid are collect­ed.
  • the pressure line 2b connecting with the pump 2a will branch off to tank 1a as well as tank 1b by the branches 2b1 and 2b2.
  • the suction tube 8 is attached with a connector 3 to a tank 4, to a suction pipe 5 or to a pouring funnel 6.
  • the suction tube connects at the other end with the air separator 9.
  • the air separator 9 comprises a control means 10, advantageously consisting of a float 10a and of shut-off parts 10b1 and 10b2 therewith connected.
  • a venting valve 11 In the upper part of the air separator 9 is located a venting valve 11, a pressure limiting valve 12 being installed in the passage 13 connecting therewith. The air is disposed to go through the pressure limiting valve 12 to the tank 1, along the passage 13.
  • a valve means 14 is located in the lower part of the air separator 9.
  • a float 10a with its shut-off member 10b2 has been disposed to close and open the valve means 14, its valve aperture 14a.
  • the liquid is caused to flow further through a shut-off valve 15 and along a passage 16 to the tank 1.
  • a liquid quantity metering means 18 In the passage 16 has been inserted a liquid quantity metering means 18.
  • the passage 16 branches, close to the tank 1, to form passages 21 and 22, and it is thus possible to make comestible liquid flow along the passage 16 either into the tank compartment 1a by the passage 22 when the shut-off valve 20b is closed and the shut-off valve 20a is open (arrow L1 ⁇ ), and when the valves are in opposite positions, comest­ible liquid may be caused to flow along the passages 16 and 21 to the tank compartment 1b (arrow L1 ⁇ ).
  • the passage 16 has, in addi­tion to the shut-off valve 15, also a shut-off valve 19 at the passage end adjacent to the tank 1.
  • the check valve 17 prevents back flow of liquid from the tank 1 to the separator 1.
  • the pressure limiting valve 12 in the flow line 13 between the venting valve 11 and the tank 1 has the effect that there is sufficient gas pressure in the air separator 9 for the liquid from the air separator 9 to flow always to the tank 1.
  • the float means 10 has been disposed to open, respectively close, the valve aperture 11a of the valve 11.
  • the float 10a assumes a position consistent with the level of the liquid that is caused to flow in.
  • the separator part 10 ascends and the shut-off member 10b2 goes into a position in which liquid flow along the passage 16 to the tank 1 is permitted.
  • the float 10a therefore controls the valve 14 in such manner that it is fully opened when the liquid level in the air separator 9 reaches the highest level.
  • the operation of the venting valve 11 is controlled with the aid of the float 10a in such manner that when the liquid reaches the highest level in the separator 9 the venting valve 11 is closed, the shut-off member 10b1 of the control means 10 closing the valve aperture 11a.
  • the venting valve 11 opens fully, and passage of air from the air separator to the tank 1, and in the embodiment indicated with solid lines in the figure advantageously to the vacuum tank, is then enabled. It is however, in this instance, a prerequisite for air flow that the pressure limiting valve 12 opens.
  • the tank 1 is a normal tank.
  • the comestible liquid is caused to flow with the aid of a pump means 25 inserted e.g. in the tube 8, not by suction effect of the vacuum in the tank 1.
  • the operation, and instrumentation, of the apparatus is equivalent to that in the vacuum tank embodiment, except that in connection with the tank 1 no apparatus producing tank vacuum is needed and the flow line 13 should not connect with the tank 1, instead of which it may open into free atmosphere after the pressure limiting valve 12.
  • the control means 10 may in one embodiment consist of a means observing the liquid level, e.g. of a float which produces signals opening and/or closing the valves 11 and/or 14 and/or 12; said signals may advantageously be, for instance, electrical control signals or pneumatic signals.
  • a vacuum is drawn (arrow L2) in the tank 1 with the pump 2a.
  • the vacuum is advantageously one of 0.4 to 0.6 bar.
  • the drive engine of the vehicle may serve as vacuum means 2a. Air is drawn from the tank 1, and thereby a vacuum created therein, by throttling the vehicle's intake air port in a manner known in itself in the art. When there is sufficient vacuum in the tank 1, the actual metering of liquid that is being collected is commenced.
  • the connector 3 of the suction tube 8 is connected either to a tank 4, to a suction pipe 5 or to a pouring funnel 6, or to another container containing liquid which is to be metered and collected.
  • the valve 7 is next opened, and liquid will start to flow through the suction tube 8 or equivalent to the air separator 9 because lower pressure prevails there.
  • the air which has separat­ed in the air separator 9 flows, guided by a control means 10, advantageously a float 10a, through the venting valve 11 and further through the pressure limiting valve 12, along the flow line 13, to the tank 1.
  • the liquid level begins to rise in the air separator 9.
  • the float 10a slowly opens the valve means 14, whereby the liquid is allowed to flow further when the shut-off valve 15 is open, therethrough and through the check valve 17 and along the pipe system 16 or equivalent to the meter 18, which meters the comestible liquid quantity that has been made to flow into the tank 1.
  • the flow of comestible liquid has been indicated with arrows L1.
  • the float 10a When the liquid level rises in the air separator 9, the float 10a with its shut-off part 10b2 controls the valve 14 and opens it fully and ultimately controls the venting valve 11 to be fully closed, doing this with the aid of the shut-off part 10b1.
  • the float 10 opens the air venting valve 11 and closes the valve 14 accordingly as the liquid level descends in the air separator 9.
  • the valve 14 closes completely and the liquid level comes to rest at a level which is always the same in view of the measuring volume. Therefore the same characteristic volume of liquid remains in the apparatus in every instance.
  • the valve 14 and the venting valve 11 may be secured in their fully open positions with the aid of screws 26a and 26b, and the same can be done in conjunction with circulatory washing.
  • the liquid flow from the air separator 9 to the metering device 18 is controlled by mediation of the liquid level sensing means 10 in the air separator 9 in such manner that when the liquid level tends to go down in the air separator the valve 14 is throttled, and when the liquid level rises the valve 14 is opened more.
  • the metering device 18 meters the liquid quantity caused to flow through the device 18.
  • the same liquid level and float, or another float is used to open and close the venting valve 11 so that when the liquid rises in the air separator 9 the valve 11 is closed as soon as the level has reached the highest operating level, and similarly it is opened when the liquid level descends from its highest level.
  • the pres­sure causing liquid flow is produced with the aid of a means 25, advantageously disposed in the suction tube 8, and thus on the intake side of the air separator 9.
  • a means 25, advantageously disposed in the suction tube 8 and thus on the intake side of the air separator 9.
  • no vacuum is produced in the tank 1; the flow is instead exclusively produced with the means 25, advantageously a pump.
