Definitions
- the invention relates to a device for removing and dosing, in particular, thixotropic pastes, preferably for highly viscous detergent pastes used in commercial laundries, from their flexible container provided with an opening, with a connection for opening to a displacement pump and with means for compressing the bag on a limited area and in the direction of the opening, so that shear forces act simultaneously on the pastes at this point and the paste is conveyed in the direction of the opening.
- Such devices are known, for. B. from DE 44 14 708 A1 or DE 44 16 089 A1.
- the paste is pressed out of the containers through the opening into the delivery line and transported from there with the displacement pump, z. B. to a mixing container.
- a base liquor is produced in this mixing container by adding water, which can then be pumped to the individual commercial washing machines without any problems.
- the invention is therefore based on the object of achieving trouble-free, precise dosing in a device of the type mentioned at the outset, even if the flexible containers filled with the pastes have air pockets.
- the suction pump be designed as a jet pump with water as the propellant.
- this type of suction pump offers advantages in terms of acquisition and operating costs and space requirements.
- the propellant used can be used to premix the pastes into a base liquor, which is necessary anyway. With a suitable choice of water pressure and nozzle cross-section, the water throughput can be adjusted according to the desired concentration of the base liquor.
- a check valve is preferably provided behind the injector.
- a particularly problem-free mode of operation of the device according to the invention can be achieved if an outlet line is connected to the outlet of the jet pump and its end on the jet pump side points upwards during operation. is. In this case, emptying of the jet pump is avoided after the device has been switched off, so that the desired suction pressure is achieved immediately after switching on again, without additional measures being required.
- the device according to the invention has proven particularly useful if the displacement pump is designed as a screw pump, in particular as an eccentric screw pump. However, the use of other positive displacement pumps is also within the scope of the invention.
- Fig. 1 is a side view of the device in a schematic representation
- Fig. 2 shows the outlet area of the positive displacement pump in an enlarged view.
- the paste dosing device has a rigid base frame 1, against which an inclined plane 2 provided in the upper region can be moved. On level 2 a polyethylene-filled bag filled with detergent paste can be placed, into the opening of which the connecting piece 3 of an eccentric screw pump 5 driven by the motor 4 projects.
- the injector 7 is operated with water from an inlet line 8 with a water inlet valve 9.
- the water-paste mixture is passed through a hose 10 to the mixing chamber 11, where it is processed in the manner known from DE 44 14 708 A1 with further water to form a base liquor, which is then pumped 12 to the individual commercial washing machines who- that can.
- the details of the device except for the area between the eccentric screw pump 5 and the mixing chamber 11 are explained in detail in the already mentioned DE 44 14 708 A1 and should therefore not be mentioned again here.
- the hose line 10 is formed into a loop immediately after connection to the injector, so that the end of the hose line 10 connected to the injector is directed upward, thereby avoiding emptying of the injector when the operation is interrupted.
- arrows to indicate the direction of flow are shown in FIG. 2.
