technical description

to the patent application of Mr. Oskar Seidl, 891 Landsberg / Lech

Augsburger Str. 36

The subject matter of the invention includes solutions that have a trouble-free Operation primarily of eccentric screw pumps in the preparation and conveyance of extremely viscous media, of media that are interspersed with long organic fiber parts and of media that have different consistencies for Make the formation of floating ceilings or sink ceilings possible.

To explain the design ideas are simple schematic Images attached:

Sheet ii

This is an eccentric screw pump flanged in the same direction in the suction line, as it is driven by a tractor by means of the PTO shaft and carried by it by means of a holding device on the linkage of the three-point hydraulic system. In this form, the pump is placed in a position that is as perpendicular as possible, but also at an angle, in the a

conveying medium admitted. Since different pit heights have to be mastered with one and the same machine, it can and after the pump is inserted into existing pit ceiling openings must be adjustable both in height and vertically. A pump is shown on the sketch, which is equipped with two suction connection flanges, which in turn can be operated alternately by means of a rotary valve

can. The pressure line, which is led upwards in this selected flow direction, is mainly used to fill the drum or for pumping into elevated tanks, the pressure line leading back into the pit has an adjustable nozzle head equipped and effected as soon as the flow rate in this Direction is directed, a hydraulic agitation effect, which from the Pressure jet coated areas. That means that in addition to the mechanical effect of the "rotating device" and the pumping effect the eccentric screw pump, which works according to the positive displacement principle, has a third hydraulic effect for processing which is then added to the media to be funded. The suction opening of the suction pipe can be enlarged in cross-section be designed as a suction funnel. In the extension of the pump rotor is a drive shaft by means of known devices flanged. The drive shaft can be engaged and disengaged. It operates a corresponding one outside of the suction funnel Wing disk worm wheel, which in turn can be equipped with appropriate cutting, tearing or striking tools can.

The working position of the "rotating device" does not have to As shown on sheet I and on the other illustrations, it can only be horizontal, but can just as easily be at an angle or at an angle. be vertical. There is also the possibility of attaching two or more such "rotating devices" that are identical or work in opposite directions, at the same speed or at different speeds and can be of the same or different size. The "rotating device" is primarily used for homogenization of different consistencies, for stirring, possibly

or spindle support the suction process.

Sheet II:. .

The arrangement sketched here is essentially identical to the arrangement shown on sheet I, but the drive shaft is to drive the device described above outside the suction pipe, the drive is also carried out in parallel not by extending the force axis of the rotor, but by means of an on and off switchable back gear on the Drive side of the pump.

Sheet III:

The pump arrangement shown here is adapted to the different suitability of the flow direction in eccentric screw pumps just. The conveying side facing the drive shaft and its seal is subjected to the lower overpressure or underpressure in the present case burdened with suction at medium heights. The technical solution of driving the ones described on sheet I. "Rotating setup" is very simple. It is done over a coupling or similar devices on the extended pump drive shaft or on an additionally provided shaft end on the countershaft or angular gear.

Sheet IV;

The drive outlined here is the described "rotating Device "allows an eccentric power transmission by means of two joints. A flexible suction hose enables together with the cardan shaft largely independent of each other Movements of the pump and the "rotating device".

Sheet V:

^ The arrangement sketched here is a rear - transverse one It is based on a tractor-mounted pump. The angular gear, which is attached in the middle or offset in front of the pump, is fitted with an output shaft provided downwards. A direct power transmission is possible via a quick coupling or power take-off shaft coupling or similar devices on the drive shaft of the "rotating device" possible. The drive shaft itself can be used as a cardan shaft or the like be executed.

Sheet VI i

The eccentric screw pump shown here is longitudinally attached " and attached to the tractor in the example shown. It can also be mounted on mobile trolleys and stationary be. The drive takes place via a gear chain or belt side drive and provides an output option for driving the "rotating device" »In this case, one of the countershaft or drive shaft driven power transmission is provided by means of a flexible shaft. Also is a drive Possible using an appropriate cardan shaft.

Sheet VII;

The pump shown here is characterized by the fact that you Sucker protrudes more or less deeply into the floating cover to be processed. The rotor is with the "rotating device" connected directly or via corresponding intermediate parts. The lowering and raising of the pump itself is done via known ones Equipment such as racks, spindles or cables. The drive shaft of the pump is designed as a sliding shaft, so far the pump is used as a tractor-mounted pump. In the case of a drive by means of an electric motor, the Electric motor can be raised and lowered together with the whole pump. The rotary valve device mentioned in the description of sheet I. to support the stirring effect is also provided and possible here.

Sheet VIII:

The detail of a suction line shown here sees an electric motor before that distresses the "rotating facility".

Sheet IX

This illustration shows an electric motor around which the pit contents are wound, which drives the "rotating device" described. operates and is designed as a submersible motor. Instead of the submersible electric motor It is also possible to attach a hydraulic motor. The possibility of using a hydraulic motor is necessary because the majority of the tractors on the market are already equipped with power delivery connections for operation are equipped with external hydraulic motors.
