Definitions

  • the invention relates to a liquid aspirator for sucking or transporting liquids, in particular solids containing liquids such as sludge or the like.
  • a liquid sucker according to the preamble of claim 1 is known from DE 102 40 804 A1 known. It has a receptacle in which a vacuum is generated via an air-suction motor. Due to the negative pressure, the liquid or the mud is sucked into the receptacle via a suction port and after filling of the container and switching off the engine via a drain and a discharge element, usually in the form of a hose, run out of the receptacle again and to a desired location be directed.
  • the British patent 241 960 already shows a lifting system for water, sewage, sand and the like, which has two lifting tanks, which are alternately filled and emptied.
  • This large-scale, permanently installed system works with the help of a complicated lever mechanism.
  • the actual suction device is spatially widely spaced from the two tanks and connected over long cable routes.
  • the complicated structure of this system is not suitable for smaller, in particular portable liquid aspirator.
  • the invention has for its object to provide a comparison with the prior art improved liquid aspirator.
  • the receptacle of the liquid aspirator is formed with at least two separate receiving chambers.
  • the main valves are coupled together so as to alternately open and close, and a control is provided by which an alternate filling and emptying of the receiving chambers is introduced with liquid.
  • the liquid or Schlammsaugvorgang be continued continuously, since always liquid can be sucked into one of the chambers, while another chamber is being emptied and thus creates space for refilling.
  • the suction motor is safely protected from contamination by the valves.
  • the liquid aspirator according to the invention operates with two receiving chambers.
  • Each of the receiving chambers may be associated with a separate motor, the controller may simply be designed so that it alternately turns on and off the motors.
  • the liquid flows from the chamber, whose engine is just turned off under its own weight, while liquid is sucked into the other receiving chamber by the other engine switched on.
  • only a suction motor is provided and the circuit is designed so that the suction side of the engine alternately is connected to the various receiving chambers, so that here too the receiving chambers are alternately filled and emptied.
  • the naturally aspirated engine can therefore pass through and is therefore more efficient.
  • liquid is sucked into it, while at the other receiving chamber no vacuum is applied, so that the liquid located there can drain under its own weight.
  • the suction motor can be designed as desired, for example as an air suction or as a vacuum pump.
  • the control can be done electronically, also as a time control. However, it is preferably designed as a mechanical control or circuit, as can be a low maintenance need and low sensitivity to external influences and possible misuse, such as tilting of the teat, reach.
  • a liquid aspirator which has two separate receiving chambers 1, 2.
  • Each receiving chamber 1, 2 is assigned its own suction motor 3, 4.
  • About the suction motors 3, 4 can in the chambers 1, 2 a Vacuum are generated, whereby liquid can be sucked into the receiving chambers 1, 2 via a suction port, not shown, which opens into the receiving chambers 1, 2 in the upper region.
  • the suction motor 3 turns off.
  • a negative pressure flap 5 closes the receiving chamber 1 at the bottom and the liquid flows via a drain 7 and an adjoining drainage element, not shown, for example a drain hose.
  • the control is performed by floats 9, 10, which are each held in a guide 11, 12 movable in the vertical direction.
  • the floats 9, 10 represent through their top configuration at the same time valves with which the receiving chambers 1, 2 can be closed against the respective suction side of the motors 3, 4, so that no liquid can be sucked into the motors.
  • the position of the floats 9, 10 is queried via signal generators, such as reed contacts or the like.
  • the signal generator gives the message "chamber full" to a control electronics, which turns off the respective motor 3, 4 and the other motor 4, 3 turns on.
  • the motors 3, 4 can also be actuated by suitably mounted switch mechanically by the action of the float 9, 10.
  • a purely time-controlled electronic circuit of the motors 3, 4 is possible.
  • FIG. 2 A particularly preferred embodiment of a liquid aspirator according to the invention is in the Fig. 2 to 11 shown.
  • the exterior view in Fig. 2 shows the housing of the liquid sucker with receptacle 13 and cover 14.
  • a Suction port 15 extends into the receptacle 13 inside.
  • Fig. 3 shows a central section through the liquid sucker.
  • This has two receiving chambers 1, 2, in which via air intake openings 17, 18 by means of a single suction motor 3 negative pressure can be generated.
  • the suction motor 3 draws in air continuously, while the air intake openings 17, 18 are alternately opened or closed by main valves 19, 20, so that only in a receiving chamber 1, 2, a negative pressure is generated.
  • the alternating opening and closing of the main valves 19, 20 is ensured by a coupling of the main valves 19, 20, which is preferred and less susceptible to mechanical failure.
  • the liquid aspirator has two receiving chambers 1, 2, the main valves 19, 20 can be connected in a particularly simple manner via a rocker 21, which is rigid in itself but pivotally mounted.
  • the movement of the main valves 19, 20 is introduced via guides 11, 12 held in a height-flexible float 9, 10.
  • the float 9 in chamber 1 has been raised to its highest possible position by the liquid sucked in, as shown, it has pressed the main valve 19 and thus opened the main valve 20.
  • the receiving chamber 1 is no longer connected to the suction side of the suction motor 3, so that in her no negative pressure prevails. Due to the dead weight of the collected in the receiving chamber 1 liquid, which is no longer compensated by the negative pressure, a negative pressure flap 5 opens, and the liquid can drain via a drain 7 and a non-illustrated discharge element connected thereto, for example a hose.
  • the emptying of the receiving chambers 1, 2 is still supported by the receiving chambers 1, 2 in the Fig. 4 and 5 shown secondary valves 23, 24 with the outlet side or pressure side of the suction motor 3 are connected.
  • the secondary valves 23, 24 are controlled so that each of the respective receiving chamber 1, 2 associated auxiliary valve 23, 24 is open when the main valve 19, 20 is closed.
  • the secondary valves 23, 24 are preferably also mechanically coupled, preferably also via a rocker 25.
  • Fig. 5 for the representation of the suction motor 3 has been removed, illustrates the principle of assisted emptying.
  • the rocker 21 of the main valves 19, 20 and the rocker 25 of the secondary valves 23, 24 are connected via a common pivot axis 26 rigidly and only together about this pivot axis 26 pivotally connected and thus mechanically coupled in a simple manner.
  • main valve 19 and secondary valve 23 of the receiving chamber 1 or main valve 20 and secondary valve 24 of the receiving chamber 2 each alternately open and close.
  • FIG. 5 also shows that the main valves 19, 20 connect to a connected to the suction side of the suction motor 3 slot-like suction chamber 27, while the secondary valves 23, 24 are in a suction chamber 27 enclosing round pressure chamber 28 which is connected to the exhaust side of the suction motor 3 ,
  • the exhaust air of the suction motor 3 does not have to be completely discharged via the auxiliary valves 23, 24 and the receiving chambers 1, 2, but can also be partially or completely discharged directly to the environment of the liquid aspirator depending on the requirement.
  • the outlet side of the suction motor 3, 4 with the receiving chambers 1, 2 via the floats 9, 10 and their guides 11, 12 are connected.
  • This is particularly advantageous when the float guides 11, 12 are surrounded to protect the floats 9, 10 and the main valves 19, 20 against contamination with a net, mesh, mesh, fleece or the like filter.
  • This filter would normally become clogged over time with dirt particles, fine algae or the like and thereby worsen the efficiency of the liquid aspirator.
  • Fig. 12 shown is the pressure chamber 28 at the outlet side of the suction motor 3, 4 side facing away from the secondary valve 24 via a connecting channel 42 with the top of the float 10 and thus the inside of the float guide 12 is connected.
  • the other, not shown side with secondary valve 23 and float 9 is formed accordingly.
  • the receiving chambers 1, 2 are arranged in a particularly space-saving manner eccentrically in one another, wherein both receiving chambers 1, 2 have a pressure-favorable substantially cylindrical shape and substantially the same receiving volumes.
  • Fig. 6 shows that the main valve 20 of the receiving chamber 2 is opened.
  • a negative pressure forms, which is sucked through the suction port 15 and an open check valve 32 liquid, symbolized by open arrows, in the receiving chamber 2.
  • the guide 12 is formed as shown at the bottom of broken, so that liquid can penetrate into the guide 12.
  • the guide 12 is formed circumferentially closed.
  • the float 10 has a seal 33 at its upper outer circumference.
  • FIG. 8 In the illustration according to Fig. 8 has already formed a negative pressure in the receiving chamber 1, whereby the negative pressure flap 5 has closed. About the suction port 15 and a receiving chamber 1 associated check valve 31 is now indicated by the open arrows liquid sucked into the receiving chamber 1. Meanwhile, there is no negative pressure in the receiving chamber 2 because of the closed main valve 20. By the weight of the Liquid therefore opens the vacuum flap 6 and the liquid flows, symbolized by the filled arrows, out of the drain 7 addition.
  • the Fig. 9 and 10 show how simultaneously with the emptying of the receiving chamber 2, the receiving chamber 1 fills with liquid.
  • Fig. 11 the process has turned around again.
  • the float 9 has closed the main valve 19 and opened the main valve 20.
  • the non-return valve 31 and the negative pressure flap 6 have closed. From the open vacuum flap 5 liquid flows through the drain 7 from the receiving chamber 1 from.
  • Fig. 13 and 14 show another embodiment of the embodiment with two vacuum flaps 5, 6.
  • a common negative pressure flap 56 are provided, which alternately closes the receiving chambers 1 and 2.
  • the receiving chambers 1 and 2 terminate at the bottom in each outlet spout 45, 46, which forms stops 55 and 66 for the vacuum flap 56 at its peripheral edges.
  • the vacuum flap is pivotally mounted between these stops 55 and 66. It may preferably be formed integrally from a single elastomeric element, wherein the pivot axis is formed as shown by a region 57 of reduced thickness.
  • the negative pressure flap 56 closes the receiving chamber 2, thereby releasing the receiving chamber 1 towards the outlet 7, so that liquid can flow out there.
  • the negative pressure flap 56 pivots into the in Fig. 14 shown position, wherein it closes the receiving chamber 1 and at the same time the receiving chamber 2 to drain the liquid collected there through the drain 7 releases. Support it the weight of the liquid collected in the receiving chamber 2 and the negative pressure applied in the receiving chamber 1 mutually, so that the pivoting of the vacuum flap 56 for opening-closing change is very fast. Also, in contrast to the embodiment of the Fig. 2 to 11 in case of delayed movement of the flaps 5, 6 no mutual interference occur.
  • Fig. 2 to 14 are extremely low maintenance, mechanically simple and functionally reliable with continuously high suction power operable.
  • Fig. 15 shows a modified embodiment with also only one suction motor 3.
  • the control, from which receiving chamber 1, 2 straight air is sucked, is in the embodiment according to Fig. 12 realized by a lever linkage with two switching levers 35, 36 which pivot a change-over flap 37, whereby the suction side of the suction motor 3 is alternately connected to the receiving chambers 1, 2.
  • the main valves are formed by the switching flap 37.
  • FIGS. 16 and 17 show yet another embodiment of a single-motor liquid aspirator according to the invention, in which the control, which receiving chamber 1, 2 is being filled, is formed by the container itself.
  • the receptacle 13 is pivotally mounted and preferably as shown oscillating around a substantially horizontal axis 38.

  • a seal of the air intake openings 17, 18 is then simplified if they have the same distance from the pivot axis or pendulum axis 38, in particular, if the local wall region of the receptacle 13 is formed bent circular segment.
  • the air intake openings 17, 18 together with the wall of the receptacle 13 also form main valves as in the embodiment of the preceding figures.
  • the mechanical connection or coupling of the main valves is in the embodiment of FIGS. 16 and 17 given by the rigid shape of the container 13 itself.
  • the pivoting of the receptacle 13 may be motorized, in particular time-controlled.
  • the receptacle 13 is subdivided into receiving chambers 1, 2, that adjusts a focus shift with increasing filling of a receiving chamber 1, 2 with liquid with simultaneous drainage of liquid from the other receiving chamber 2, 1.
  • the receptacle 13 is automatically pivoted to a position which releases the other receiving chamber 2, 1 for filling, while a receiving chamber 1, 2 emptied.
