Definitions

  • the invention relates to a concrete mixer with a drum in which mixed material composed of concrete components and mixing water which can be introduced via a water supply line can be mixed by means of mixing elements, and at least one vibrator which can be excited to introduce vibration energy into the mixed material.
  • a mixer of this type is known from US-A-4148 588.
  • the rotating drum for concrete production there has supply openings on its ceiling into which a liquid batch with the concrete components is fed.
  • Mixing is improved by means of vibrators, each of which is excited by an unbalance motor on a vibrating plate. Due to the arrangement of the oscillating plate and the unbalance motors, the mixer is complex to construct. Furthermore, the energy requirement appears to be relatively high.
  • each vibrator is arranged in the wall area.
  • the part of each vibrator that acts directly on the mix consists of a plate that is adapted to the curvature of the mixing vessel wall and covers a corresponding wall opening from the inside of the mixer. It is connected to the wall by an elastic partition wall, which covers the opening and at the same time is intended to prevent transmission of the shaking movement to the vessel wall.
  • Each plate is assigned its own drive in the form of an unbalanced electric vibrator, which is located outside the mixing container.
  • This known mixer is structurally extremely complex due to the necessary openings in the drum wall, the exact adaptation of the corresponding vibrator plate and the associated seals, and the need for a plurality of our own unbalance vibrators. It must be doubted whether the specified effect of the shaking movement on the mix is actually achieved. Further disadvantages are the considerable susceptibility to faults, since the elastic seal is reached by the mix and is attacked over time; in addition, a transmission of the shaking movement to the drum cannot be prevented by the seal either, so that the mixing container and its storage, as well as that of the mixer shaft, are exposed to increased wear.
  • the drive of several, in the exemplary embodiment four vibrators also requires a relatively high additional energy expenditure.
  • the object of the invention is to provide a mixer of the type described in the introduction, the vibrator of which provides a desired mixing effect with a simple structure and economical use of energy.
  • the mixing water serves as the drive for the vibrator, which is either made to pulsate by means of a pulsating pump, or itself drives a pulsator or a turbine which interacts with a rotating unbalance.
  • the water required for the mixture is definitely supplied to the inside of the drum.
  • the lines, seals and connections required for this therefore do not represent any additional construction work. It has surprisingly been found that the time required for introducing the mixing water is also sufficient as vibration time in order to achieve the desired mixing result.
  • the pressure fluid forming the vibrator drive in the line loop differs as far as possible in its density from the filling fluid in order to achieve an efficient vibration arrangement.
  • the hydraulic fluid is intended exclusively as a drive for the vibrator, for no further use.
  • it is envisaged to feed and discharge perforated pipes which pass through the filling liquid through the wall of the vibrator.
  • z. B. thought of the supply of hot water for heating the vibrator body and thus the material to be shaken. From this and the mentioned difference in density it can be seen that water is essentially not considered in the hydraulic fluid.
  • the idea of influencing the filling liquid as part of the vibrator Using the mixture has nothing to do with mixing water for the mixture as the drive for the vibrator.
  • the introduction of the necessary vibration energy by water can be done in various ways according to the invention.
  • the mixing water can already be stimulated outside the drum, but also in the same, to pulsate.
  • the feature of claim 2 relates to a structurally particularly simple form of the vibrator.
  • the mixing water which has come out of the water supply device and which has caused it to pulsate to be mixed with another water which is not associated with the water supply device Vibrate the body, for example by impact.
  • Claim 3 relates to an embodiment which has a particularly simple way of supplying energy to the vibrator.
  • the feature of claim 4 prevents the vibration movement of the pipe section, which serves as a vibrator, from rocking to an undesirable height.
  • the concrete mixer shown in Fig. 1 has a drum 1 which is rotatably mounted in a bearing block 2 by means of a shaft 3.
  • the drum 1 and the bearing block 2 are supported on a frame designated as a whole by 4.
  • the frame 4 can be arranged in a stationary manner or can be part of a mobile ready-mixed concrete mixer.
  • a water tank 5 is also held in the area of the bearing block 2.
  • the inside of the drum 1, shown schematically open, has mixing elements 6 in the form of vane plates which extend spirally on the inner wall over the entire length of the drum.
  • a filler neck 7 is arranged at the drum mouth.
  • a water supply line, designated as a whole by 8 enters drum 1 in the region of the drum mouth.
  • the water pipe part 8a located outside the drum 1 contains a pump 9 for the water supply.
  • the connection between the pump 9 and the water tank 5 is not shown for the sake of clarity.
  • the water pipe part 8a located outside the drum 1 is connected to the water pipe part 8b located in the drum via a rotary coupling 10.
  • the water pipe part 8b located in the drum 1 extends to the area of the drum bottom 1 a, and is bent there again towards the inside of the drum.
  • the last section of the water pipe part 8b forms a pipe section 11 which extends approximately parallel to the longitudinal axis A of the drum.
  • a pulsator 13 is arranged between the outlet nozzle 12 and the pipe section 11 and causes intermittent water leakage.
  • the pipe section 11, which is elastically supported over the angled part of the water pipe part 8b, is thereby excited to vibrate. These vibrations are dampened by a resilient support 14 which is supported on the drum base 1 a and bears against the pipe section 11.
  • the dry concrete components are fed into the rotating drum via the filler neck 7 and mixed together by the mixing elements 6.
  • the mixing water necessary for the production of concrete is supplied via the water supply line 8. It flows intermittently from the outlet nozzle 12 into the component mixture and already generates vibrations in it.
  • the tube section 11 is caused to vibrate by the intermittent water outlet. The vibration is transmitted to the container contents surrounding the pipe section 11. The internal friction of the material to be mixed is reduced to such an extent that the mixing action of the drum 1 and the mixing elements 6 is increased and the mixing time is reduced accordingly.
  • FIG. 1 shows an embodiment of a mixer which is largely similar in design to that of FIG. 1.
  • the components are therefore provided with the same reference numerals.
  • 2 has, in addition to the pump 9 for the water transport, a pressure booster system 15 for a pulsating medium. It can e.g. a piston pump, a diaphragm pump or a screw pump. In the embodiment according to FIG. 2, this pressure booster system is combined with the pump 9 to form one structural unit. No pulsator 13 is thus provided in the area of the outlet nozzle 12.
  • the concrete mixer shown in FIG. 3 differs from that shown in FIG. 2 in that the pressure booster system 15 is not installed outside the drum 1 in the area of the pump 9, but inside the drum 1 in the area of the drum bottom 1a in the water line part 8b .
  • the necessary energy is supplied in a manner not shown in the area of the bearing for the shaft 3.
  • the concrete mixer according to FIG. 4 has a pressure booster system 15 'in the area of the drum base 1a, which, however, only increases the water pressure, while a pulsator 13 is additionally arranged in the area of the outlet nozzle 12.
  • the pipe section 11 is provided with arms 16 which in turn carry outlet nozzles 12. Since the pulsator 13 exits the outlet nozzles 12 intermittently, each of the arms 16 forms a vibrator in itself.
  • FIGS. 6 to 8 show drums 1 without support and with vibrator designs which have already been shown essentially in the previous embodiments.
  • the same reference numerals are therefore also used for the same or almost the same elements.
  • the main difference between these embodiments and those already described The other is that the water supply line 8 opens directly into the tube section 11 through the drum base 1a.
  • the water supply line 8 passes through the drum drive 17 and the hollow shaft 3 ′ here.
  • a rotary coupling 10 is switched into the water supply line 8.
  • the pipe section 11 in FIG. 1 is equipped with a pulsator 13 directly in front of the outlet nozzle 12.
  • a resilient support 14 extends between the drum base 1 a and the pipe section 11.
  • the water is supplied by means of a normal pump 9.
  • the pump 9 deliveryvers the water to be supplied already pulsating.
  • the drum 1 ' is a design for a free-fall mixer. Another difference from the embodiment according to FIG. 1 is that there is no resilient support 14.
  • FIGS. 9 and 10 each show a plate 18 of a plate mixer in plan view.
  • Pipe sections 11 with angled outlet nozzles 12 serve as vibrators, as in the previous embodiments. They are supplied with pulsed mixing water in a manner not shown and are stimulated to vibrate by the water outlet.
  • the tube sections 11 are attached to a central rotating body 19 which can be driven for mixing.
  • mixing tools 20 are additionally connected to the pipe sections 11.
  • only the pipe sections 11 are mounted on the rotating body 19.
  • FIGS. 11 and 12 show the drums 1 which are largely the same as in the previous embodiments.
  • a pipe section 11 ′ which is elastically mounted on the drum base 1 a is supplied with the mixing water via the water supply line 8 in the manner already described by means of a pump 9.
  • the tube section 11 ' carries at its end remote from the drum base a turbine housing 21 with a turbine wheel 22.
  • the turbine wheel 22 is connected to an imbalance 23.
  • the mixing water drives the turbine wheel 22 to rotate, as a result of which the unbalance 23 sets the turbine housing and thus the pipe section 11 in vibration.
  • the mixing water leaves the turbine housing 21 through an outlet nozzle 12 arranged on the side thereof.
