Description

The present invention relates to a loading device for filling tank-shaped containers with bulk goods the note specified in the preamble of claim 1 to paint.

A loading device is known from the prior art a two telescopic, interlocking cover known for its comprehensive loading set.

On the one hand, this loading set has the disadvantage that that through the annular gap between the telescopic loading a pronounced dust outlet through the pipes takes place.

This discharge of dust often leads to a considerable change world pollution, for the health of the operator personnel as well as to impair safety at work.

Another disadvantage of the well-known loading set with Telescopic loading tubes is that in the Ring gaps between the telescopic loading tubes regularly Put down dusty bulk material residues.

This is particularly the case when changing products as well the aspect of a considerable cleaning effort and un in terms of hygiene and quality extremely worrying.

In addition, for example, a hygroscopic bulk Good residue in the ring gaps to stick the Te leskoprohre and thus a significant impairment the functionality of the telescopic loading tubes.  

DE 37 08 653 A1 describes a loading device for loose loading of dusty bulk goods known, the egg loading trunk from extendable telescopic tubes has. For essentially trouble-free entry and exit Ren of the telescopic tubes are usual spacers see. A balgenar is used to shield the environment from dust provided jacket that extends the telescopic Encloses pipes. The telescopic tubes are therefore not self-sealed and are therefore subject to Strong dust pollution on the inside and outside. Further is the maintenance of the loading device due to the Bellow-shaped sheathing enclosing telescopic tubes effort.

In contrast, a loading is from DE 84 24 067.9 U1 hose known, which completely in its inner life interlocking telescopic tubes are dispensed with. The flexi ble loading hose also allows expansion and retraction ren of the loading device. Around the outlet cone on the stream downward end of the loading hose at the filling dome of the Fixing the loading container in a sealed manner is a ring shaped, inflatable, elastic hose on a zy Lindischer end portion of the discharge funnel provided. A disadvantage of this device is that the bulk material is led directly into the loading hose and this consequently subject to increased wear and tear for vie le applications is unusable.

Furthermore, DE 15 96 971 A1 describes a self-cleaning one Inlet for adhesive dosing goods in mixer or processing tion machines known in which a flexible downpipe with a vibrating amplitude can be applied to it solving bulk goods.

The object of the present invention is therefore the ready position of a loading device with one another bar telescopic loading tubes, which the problem of a Dust escaping from the ring gaps between the telescopic Does not know tubes and their telescopic tubes themselves the loading of a dusty bulk material from one another are solvable and an effortless, stop-free process the telescopic tubes allowed into each other.

According to the invention, this task is performed in a generic manner ß device by the in the characterizing part of Pa Features specified 1 solved. Especially be preferred embodiments are the subject of the Unteran claims.

An embodiment of the invention is based on the Drawing described in more detail.

Fig. 1 shows a schematic cross section through a loading device according to the invention with telescopic loading tube parts which can be pushed into one another.

As can already be seen in Fig. 1, the loading device according to the invention for filling tank-shaped containers ( 1 ) with bulk material generally comprises at least one or more outlet openings having a loading nozzle ( 2 ), at least one on the loading nozzle ( 2 ) indirectly or Immediately upstream one-part or multi-part telescopic tube ( 3 ) and at least one one-part or multi-part adjusting element ( 4 ) for essentially vertical and / or horizontal and / or oblique adjustment of the loading nozzle ( 2 ).

An essential feature of the Beladevor device according to the invention is that the annular gap or gaps ( 5 ) between the telescopic tube parts ( 3 ) can be sealed by at least one one-part or multi-part pneumatically and / or hydraulically inflatable sealing sleeve ( 6 ).

The provision of the possibly annular and tubular sealing sleeve ( 6 ) prevents dust from escaping through the annular gaps ( 5 ) between the telescopic loading tube parts. On the other hand, it prevents dust-like bulk residues from penetrating and forming in the annular gaps ( 5 ), thereby ensuring that functionality remains intact, in particular the free displacement of the telescopic tube parts ( 3 ) into one another.

The contact area of the loading nozzle ( 2 ) which can be connected to the filling opening of the container ( 1 ) is, for example, essentially conical, plate-shaped, ring-shaped, tubular or cylindrical. As a rule, this contact area of the loading nozzle ( 2 ) is designed in such a way that a dust-tight and / or gas-tight connection to the container opening is ensured. For this purpose, for example, a pneumatically or hydraulically inflatable sealing sleeve ( 7 ) can be provided, which preferably has the shape of a hose ring.

In particularly preferred embodiments, the sealing sleeves ( 6 , 7 ) are designed, for example, essentially in the form of at least partially or completely encircling hollow tubes.

The sealing sleeve ( 6 ) between the telescopic tube parts ( 3 ) usually seals the annular gap ( 5 ) between the telescopic tube parts ( 3 ) when inflated. Additionally or alternatively, it can fix the position of the telescopic tube parts ( 3 ) to one another.

The sealing collar ( 7 ) of the loading nozzle ( 2 ) is designed such that you in the inflated state between the container opening and the inserted telescopic tube part ( 3 ) existing dust and / or gas tight seal.

In particular, for cleaning purposes of the telescopic loading tube parts ( 3 ) and / or the loading nozzle ( 2 ), for example, one or more drive elements ( 8 ) can be substantially horizontal and / or diagonally, directly or indirectly, with a shaking, tapping or shaking movement, at least in sections act on the wall of the telescopic pipe parts ( 3 ) and / or the loading socket ( 2 ).

In particularly preferred embodiments, the one or more drive elements ( 8 ) for substantially horizontal and / or oblique shaking, tapping or shaking tel displacement of the telescopic tube parts ( 3 ) and / or the loading nozzle ( 2 ) are permanent or temporary , in particular at the end of loading, once or with formation of a shaking, tapping or shaking movement of the telescopic tube parts ( 3 ) and / or the loading nozzle ( 2 ) can be activated several times in succession.

The at least one adjustment element ( 4 ) for vertical and / or horizontal and / or inclined adjustment of the loading port ( 2 ) can be, for example, in the form of a hydraulic or pneumatic lifting cylinder, knocker, egg spring mechanism, a manually and / or electrically operated cable pull mechanism, racks - Or spin delantriebes, a lifting device, a Hebelvorrich device or an eccentric disc, each without or in Ver connection with counterweights and alone or in combination with each other, be formed.

The same applies to the drive element ( 8 ) for exercising an essentially horizontal and / or oblique shaking, tapping or shaking movement on the walls of the telescopic tube part (s) ( 3 ) and / or the loading connector ( 2 ).

In summary, it can be stated that thanks to the one or more sealing sleeves ( 6 ) in the annular gaps ( 5 ) any dust escape is prevented. A risk to health, an impairment of safety at the workplace as well as environmental pollution from escaping bulk goods are safely avoided.

The sealing sleeves ( 6 ) also prevent the powdery bulk material from penetrating into the annular gaps ( 5 ). The cleaning of the loading device according to the invention is therefore particularly simple and effortless. Also from the point of view of hygiene and quality assurance, the prevention of the penetration, remaining and release of bulk material residues in or out of the annular gaps ( 5 ) is extremely advantageous.

The prevention of the penetration of bulk material residues into the annular gap ( 5 ) also leads to the advantage that ei ne easy movement of the telescopic tube parts ( 3 ), especially after the end of the pressurization of the sealing sleeves ( 6 ), is always guaranteed.
