Definitions
- the invention relates to a two-cylinder high-pressure pump according to the preamble of claim 1.
- the thick matter pump according to the invention serves to promote Substances or mixtures of substances from muddy to viscous Consistency, which is preferably solid particles in a particular May contain concentration.
- An example of such Mixtures of materials forms concrete, in which the solid particles of sand and Gravel grains are present.
- Such pumps convey the thick matter with their alternating suction and delivery cylinders under pressure through a delivery line.
- One serves the cylinders upstream filling container, the suction feed cylinder to offer a sufficiently large amount of the thick matter.
- the filling container therefore has an agitator, which on the one hand keeps the thick matter in motion in the container and on the other hand feeds the openings of the feed cylinders, so that they cannot suck in air during normal operation.
- To the shaft of the agitator is arranged in the filling container and carries stirring tools, which have a conveying effect in the direction the cylinder openings result and usually the shape of have paddles.
- Pipe slide valve which forms the end of the delivery line, with this but is articulated.
- the free end of the pipe slide moves between the two openings of the feed cylinder in time with the intake and Delivery strokes of their pistons, so that the delivery cylinder Thick material is pressed into the inlet leg of the pipe slide valve the opening of the other feed cylinder is released, d. H. in direct connection with those contained in the feed cylinder Thick matter stands and sucks it.
- the one in the entry leg thick matter conveyed under pressure gets into the Exit leg of the slide valve and then occurs immediately from this into the delivery line.
- the Two-cylinder high-pressure pump according to the invention as a car pump is mobile, there is a need to adjust the height of the filling container to restrict. Then a sufficient filling volume is required a relatively large width of the filling container and a funnel-shaped inclination of at least its front wall, d. H. the wall that is in extension of the feed cylinder outside is arranged, while the rear wall delimiting the filling container forms at the delivery cylinder ends.
- the arrangement of the Pipe slide valve in the filling container, which in the invention Two-cylinder high-pressure pump is provided that leads to a movement in addition to the agitator in the thick matter results as soon as the pipe slide valve makes its control movements receives.
- Such two-cylinder high-density pumps are already available as concrete pumps known (DE-AS 23 15 857). This results in the arrangement the paddle at the ends of the agitator shaft in immediate Close to the side wall of the filling container. Between the circles, which the paddles arranged outside when the Describe the agitator shaft, the openings of the cylinders. The inlet leg of the tube slide valve is in front of the cylinder openings arranged in the filling container.
- the paddle can use the two-cylinder thick matter pump to remove the thick matter Do not feed directly to the cylinder openings for suction exclude air into the delivery cylinder during the suction cycle, because the one that goes back and forth in front of the cylinder openings Inlet leg of the pipe slide between the middle space the two paddles on the agitator shaft. That is why the paddles have the desired loosening effect in the middle area of the filling container in front of the cylinder openings not instead. In operation it therefore happens that in this middle area the thick material thickens and for example in the case of concrete, it forms a bridge which is used to suck in the concrete hindered or even prevented in the cylinders. This will at least the delivery rate, especially for concrete pumps greatly reduced.
- two-cylinder thick matter pumps are known (US Pat. No. 3,929,400), in which a pipe slide is arranged with its outlet leg behind the agitator shaft on the rear wall of the filling container of a two-cylinder thick matter pump.
- the inlet openings of the feed cylinders are arranged behind the rear wall of the container and the outlet leg is located between the agitator shaft and the rear wall of the filling container.
- the inlet and outlet legs of the pipe slide form an approximately right-angled L-shaped overall arrangement, the outlet leg being oriented vertically and the inlet leg leading to the two-cylinder thick matter pump running horizontally.
- the object of the invention is to develop a two-cylinder thick matter pump of the generic type in such a way that, after the thick matter conveyance has ended, the thick matter, which can only be removed with difficulty, is to be reduced.
- the central axis of the exit leg towards the back wall of the filling container the vertical is inclined so that the entry leg of the L-shaped Unit faces down.
- the cylinder openings are here deeper than the bottom of the filling container, creating the residual thick be kept low in the filling container after the thick matter has been conveyed can, with the agitator the thick matter to the middle of the Filling container promotes.
- the advantage of such a two-cylinder high-pressure pump is also that after the shutdown of the Funding no longer eligible thick matter independently of the filling volume of the filling container.
- the level of the filler by sufficient Enlargement of the filling container without difficulty lift so far that when the thick material is sucked in, no suction craters at high suction speed in the filling container can form, get through the air into the feed cylinder can. Loss of thick matter and disposal difficulties with Clearing out the no longer recoverable thick matter residue from the Filling containers can be significantly reduced as a result.
- the cylinder openings are lower than the bottom of the filling container a hydrostatic thick matter in front of the respective suction opening or concrete pressure available, which corresponds to the height of the filling container bottom exceeds, so that at the end of the conveyor operation the filling container can be practically emptied.
- the invention also the features of the claim 4, after which u. a. the rotary bearing of the pipe slide, which whose control movements allow on the outside of the Rear wall of the filling container is arranged.
- the upper one Make the opening of the filling container completely free and given Dimensions of the filling container the narrowing of the filling opening through the pipe valve, with L-shaped pipe valves mainly through its exit leg to a minimum to reduce.
- the cylinder openings laid in a specially built channel-shaped housing which is closed except for an opening in the filling container is.
- the channel shape encloses the entry leg of the Pipe slide valve and ensures that the of the entry leg displacement of the pipe switch caused by swiveling remains low. This is desirable because the Swiveling the pipe slide on the back of the entry leg occurring stern wave no longer to a cavity leads and thereby improves the filling of the suction cylinder becomes.
- the driving forces of the Pipe switch which is also a significant advantage.
- the generally designated 1 slurry pump according to the Embodiment has a filling container 2, in the of above the concrete to be conveyed, for example from a truck mixer is introduced via a slide.
- the filling container has a rectangular opening 3, the parallel longer sides of which Form front wall 4 and a rear wall 5.
- the floor plans of the Side walls 6 and 7 show a lower arch 8 and diverging Leg 9 or 10. This results in an open top Trough shape of the filling container 2.
- a filling shaft 2 passes through an agitator shaft 11.
- This is equipped with stirring tools, which non-rotatably attached to the shaft and offset against each other as well spaced apart in the longitudinal direction of the shaft are.
- the stirring tools 12 to 14 are symmetrical to Longitudinal plane of the filling container 3 arranged and range with increasing Atomic number up to the exit leg 15 one generally designated 16, the other Leg serves as an entry leg for the concrete and with the Exit leg 15 includes an angle of approximately 90 °.
- a pivot bearing 20 supports the pipe slide 16 on a crossbar 21 starting at 22 and 23 at both ends of rising Supports is worn.
- a channel-shaped housing 24 has its inner opening 25 flanged to the tank bottom at 26.
- the housing 24 has an arcuate rear wall 27 whose arc of pivoting movement of the entry leg corresponds.
- On the inside of the arcuate wall 27 sits an eyeglass plate 28 while a Cutting ring 29 the wearable end of the entry leg 17th forms and with a rubber-elastic seal 30 against the Glasses plate 28 is pressed.
- connection housing 31 which hinges on both sides to rising Supports 32 and 33 are connected to form the connection to the feed cylinders 34 and 35.
- the glasses plate encloses the two openings 45 and 46, through which the feed cylinders 34, 35 suck or through the Promote pipe slider 16 in the delivery line 19 concrete.
- This Openings form the inner end of two pipe sockets 38 and 39, which face outward from the arcuate rear wall 27 of the channel housing 24 are curved to the design lateral distance between the two feed cylinders 34 and 35 with to bridge their pistons 36 and 37.
- the L-shaped unit from the entry leg 17 and the Exit leg 15 and the 90 ° elbow of the pipe slide 16 is towards the rear towards the rear wall 5 of the filling container 2 and the delivery cylinders 34, 35 behind it by approx. 30 ° inclined.
- the entry leg 17 and the him enclosing channel housing 24 down.
- Under the opening of the channel housing in the filling container 2 results from this Chute 47, on which the concrete in front of the delivery cylinder openings 45 and 46 is funded.
- the pipe slide 16 swings in time with the opposing pistons 36 and 37 in front of the feed cylinder openings of the intake Piston 37 about the longitudinal axis of its outlet leg 15 in the bearing 20 and the pipe swivel 18 of the delivery line 19.
- the pipe slide is also with the pin 48 of his lower drive shaft 40 supported on the bottom of the chute 47. Transfer a lower drive 41 or an upper drive 42 the kinetic energy for the pipe slide on the shaft 40 or the upper end of the outlet leg 15 between the Bearing 20 and the tubular swivel joint 18th
