Definitions

  • the invention relates to a sewage lifting plant according to the Preamble of claim 1.
  • a sewage lifting plant is by the German patent DE 36 07 353 C2 known.
  • the known wastewater lifting plant comprises two bulky material collection rooms, which the wastewater contaminated with bulky substances is fed, as well as a common collection container for the one that has been freed of bulky materials and pre-cleaned Wastewater from each bulky material collection room via a connecting line to the collection container flows.
  • Each emptying agent collection room is for emptying the collecting container a pump assigned, which during operation Waste water flow through the respective connection line and through the respective bulk material collection space in a pressure pipeline conveys and pumps.
  • Each connection line is in the known sewage lifting plant a locking device associated with the Task has one during the filling process of the collecting container Outlet opening in the connection line to the collection container to release and the connection to the concerned Shut off the pump at least partially, so that the pre-cleaned Waste water completely or for the most part this outlet opening and not through the pump in the Collection container can flow.
  • centrifugal pumps used it is not harmful if one low proportion flows through the pump to this flush out.
  • the closing device also has the task of the outlet opening to lock and lock when assigned Pump is on and the collection container emptied. Through the then closed outlet opening ensures that the pumped pump Waste water flow completely enters the pressure pipeline and not pumped back into the collection container becomes.
  • the locking device by a spring Return regulation flap formed by the spring into a connecting line to the pump partially blocking position is brought. simultaneously is the one leading directly into the collection container Outlet opening in the connecting line released.
  • the Return regulation flap through the wastewater flow brought into a position against the spring force in which the outlet opening in the connecting line closes.
  • flaps can occur during operation occur when the return flow control valve is in its the closing position blocking the outlet opening becomes. Such flaps can be too mechanical Vibrations that occur over the pipes reproduce and possibly also acoustically as sounds Beats are noticeable.
  • the invention has for its object an improved To create sewage lifting plant, which also in the Overload operation when large amounts of waste water are generated a safe functioning with regard to opening and the exit openings are closed and is inexpensive to implement.
  • Forced control is provided in the invention, which ensures that the outlet openings in the Connection lines through the locking devices in Dependence of the respective operating state of the pumps are mutually released or blocked. Thereby is achieved that the pump in operation assigned exit opening blocked on the one hand and the other outlet opening, that of the other not switched on pump is assigned, forcibly simultaneously is automatically released.
  • each locking device is by a ball formed, which fastened in a to the connecting line Ball housing, which is the outlet opening has.
  • the use of a ball has the advantage that because of the round surface has no edges.
  • the ball can move freely within the ball housing and is supported by the Wastewater washed free because the ball is completely from that Waste water can be washed around and incrustations washed away become. This also leads to a longer lifespan Closing device.
  • the two balls of the locking device mechanically coupled. This will make the desired forced control ensured, which ensures that the one exit opening is inevitably closed, when the other outlet is open.
  • the two balls are advantageously a common one Rocker assigned by each of the two balls around one
  • the pivot point can be pivoted into a respective end position.
  • the the ball blocking the outlet opening actuates the rocker, which then inevitably and simultaneously on the other ball acts so that this the assigned outlet opening releases.
  • the plastic balls which turns out to be special robust and resistant in terms of long life has proven.
  • the balls can be hollow and with Fiber can be filled to the specific weight to influence the balls.
  • the specific weight can be used to determine the closing behavior of the balls to influence and optimize.
  • FIG. 1 shows a sewage elevator 10 in a along the line of symmetry 48 shown unfolded representation.
  • the left and right are the Line of symmetry 48 actually located in the Drawing level one above the other.
  • the sewage lifting unit 10 comprises a housing 12 with a Ventilation opening 14. Inside the housing 12 two bulky material collecting spaces 20 and a common one Collecting container 30. Each bulky material collecting space 20 is one Pump 26 assigned outside the housing 12.
  • Each connecting line 24 is a locking device 36 assigned, the closer structure below based on 2-7 is explained.
  • arrow A illustrates that the closing device at least the way to the right pump 26 mostly shut off, so that the pre-cleaned Waste water from the connecting line 24 directly into the Collection container 30 arrives.
  • This is a bypass released in parallel to the pump 26 by the pre-cleaned Waste water not through the stationary pump 26, but arrives directly in the collecting container 30.
  • the real one Locking device 36 is by two balls 58 and 60 formed, each within a ball housing 62nd are arranged vertically movable.
  • the ball housing 62 is connected below to the connecting line 24 and has an outlet opening at its upper end 38 or 40 through which the inflow from the connecting line 24 through the ball housing 62 to the collecting container 20 is released or blocked by the balls 58, 60.
  • the two balls 58, 60 have a common rocker 50 each assigned to an actuating arm 52 and 54.
  • the Rocker 50 is pivotable about a hinge point 56 and forms a mechanical coupling between the two balls 58 and 60.
  • FIGS. 4 and 5 Another exemplary embodiment is shown in FIGS. 4 and 5 shown.
  • the outlet openings 38, 40 are mutually spaced apart, and the two Balls 58 and 60 are rigid with one another via a rod 64 connected.
  • Figs. 2 to 5 are preferred if the pumps are used as Centrifugal pumps are designed and large volume flows or large amounts of waste water occur. This means z. B. in the illustration shown in Fig. 3 that about the left connecting pipe 24 flowing waste water the opened outlet opening 38 into the collecting container can flow, and that at the same time also part of the Waste water through the centrifugal pump itself into the collection container arrives, the impeller of the centrifugal pump from any deposits can be washed away. Because of the large volume flows suffice for balls 58 and 60 influenced by the wastewater flow itself then in the manner described the one ball over the mechanical coupling by means of the rocker 50 is inevitable acts on the other ball.
  • a locking device 36 in contrast, the balls 58, 60 influenced by a control device 42 and controlled.
  • the control device 42 has a lower one Push rod 44, which is connected to rocker 50 via a joint 46 or the actuating arm 54 is connected.
  • the rocker 50 When switching one of the two pumps will push rod 44 either in the direction of arrow G down (Fig. 6) or moved in the direction of arrow H (Fig. 7).
  • the rocker 50 inevitably takes one of the two 6 and 7 positions shown in which their Actuate actuating arms 52 and 54 on balls 58 and 60, respectively and either release the outlet openings 38, 40 or close. Because of the forced control is there again the one outlet opening 38, 40 is closed, while the other outlet 38, 40 automatically is released.
  • This embodiment is used when using positive displacement pumps preferred if the amount of waste water is not so large is. Without the forced control by the control device 42 and the push rod 44 can namely There is a risk that the balls 58, 60 because of the comparatively low volume flows of the wastewater safely assume their respective closed positions can what is avoided by the control device 42 that is, along with turning on one of the pumps is actuated in each case.
