Definitions

• the invention relates to a suspension device for a submersible mixer, consisting of a guide rail which can be mounted in an approximately vertical position in a liquid container, a fastening device which can be moved on the guide rail and can be locked at various heights, and a coupling part which projects laterally therefrom for holding purposes of the submersible mixer.
• the coupling part is designed as a console on which the submersible motor agitator is fastened in an approximately horizontal arrangement, the axis of the submersible motor agitator intersecting that of the vertical guide rail.
• the invention is based on the object of making the suspension device simpler and of making the possibilities for angular adjustment of the submersible mixer versatile.
• this object is achieved in that on the side of the housing of the submersible agitator there is provided a counter-coupling part which is approximately perpendicular to the longitudinal axis thereof and which can be connected to the coupling part of the fastening device in a plurality of angular positions. Due to the lateral arrangement of the counter coupling part, the submersible mixer can be positioned relatively close to the vertical guide rail, so that no heavy brackets are required for mounting. A simple, relatively lightweight counter-coupling part is sufficient to hold the submersible mixer on the coupling part of the fastening device which can be moved on the guide rail. The lateral arrangement also saves space to a not inconsiderable extent.
• the side bracket also makes it possible to rotate the submersible mixer by 360 ° relative to the guide rail and to fix it in a wide variety of positions.
• the submersible mixer can always be positioned in such a way that all areas of the liquid container can be optimally circulated without any lengthy assembly work.
• the counter-coupling part is preferably arranged approximately in the plane of the center of gravity of the submersible mixer.
• the clamp is appropriately divided in half.

• the other part can have the shape of a semicircular arc.
• the two clamp parts can be attached to each other in a conventional manner by means of screws which reach through angled flanges.
• At least one eyelet is preferably provided on the clamp for fastening a traction cable for lifting and lowering the submersible motor agitator.
• One coupling part can be designed as a sleeve, while the other coupling part has the shape of a pin engaging in it.
• the coupling is achieved in that the one coupling part has at least one transverse bore and the other coupling part has a plurality of transverse bores arranged offset in the circumferential direction from one another, the transverse bores being able to coincide with one another and the two coupling parts by means of a holder which can be inserted into the mutually aligned transverse bores pins are lockable relative to each other.
• a row of transverse bores is expediently formed on the journal along a surface line, while a plurality of rows of transverse bores are arranged on the sleeve which are offset with respect to one another in the circumferential direction and each run along a helical line, the number of transverse bores of each row of the Pin and the sleeve is the same.
• each row is formed from four cross bores.
• transverse bores While a single row of transverse bores is provided on the pin, which can be of full or hollow design, six, eight or twelve rows of transverse bores can be formed on the sleeve, for example, depending on the diameter, with the last transverse bore of the one row of the row first transverse bore of the following row in the circumferential direction has the same distance as to the penultimate cross hole in its own row. For example, if the sleeve has twelve rows of holes, forty-eight angle settings are possible, which are evenly distributed over 360 °.
