Abstract

Emptying device for big bags or similar flexible containers comprising a housing (1) with an attachment funnel (2) for placing a big bag (3), a pipe socket (4) being arranged in the center of the outlet direction in the housing (1), characterized in that the pipe socket (4) is surrounded by a sack buckle (9) in the upper region facing an opening (7) of the attachment funnel (2) and the pipe socket is arranged at a distance from the opening (7).

Description

The invention relates to an emptying device for big bags or the like flexible container, which is particularly applicable for low-dust emptying of big bags.

Sack-like containers such. B. Big Bags u. a. used for the transport and storage of flowable bulk materials such as grain or granules. They have a low weight and occupy little space for storage in the empty state. Its bottom has an opening which can be closed by means of tape or the like, wherein the closure can be made double.

Stability and dimensional accuracy are not sufficient, so that usually additional measures for bagging, loading / transport and emptying are required.

It is from the DE-C-3429167 It is known to set up a big bag for emptying with the bottom part on a vibrating element with adjustable vibrating amplitude in order to be able to discharge poorly flowing bulk material.

An emptying device according to DE-A-102007021124 On the other hand, it has lifting and lowering elements that act on the underside of a big bag and make it funnel-shaped. When an element is raised, another element is lowered at the same time, so that the bulk material should only flow to the central outlet to the middle of the underside. Required is a frame with sack lifting harness, etc. A similar solution with a rocker instead of the elements is in the DE-C-19740437 disclosed.

In order to empty a large soft packaging with low emissions, is in the DE-A-102005021368 proposed to guide the outlet hose of the soft packaging radially inwardly by an annular sealing device, below subsequently below the outside to push over a connecting piece and to expand the sealing device.

When emptying after DE-U-202009017605 should a high tightness when filling in a tanker with a simple design of the device can be achieved. For this purpose, the device has a working platform with a holding device for the big bag, which includes a pipe guide as a chute, wherein the outlet spout of the big bag is used after its opening under automatic sealing in the pipe guide. The latter requires a corresponding design of the spout and suspension of the bag on a hanging train. A dosage during filling is not given. A similar solution, but with a funnel-shaped inlet to a tubular outlet shows the DE-U-2960022 ,

The invention has for its object to provide an emptying device for Big Bags or the like flexible container, which is simple and manageable and which is particularly applicable for low-dust emptying of big bags. The object is achieved with the features of the protection claim 1. A pipe socket, which is surrounded in the upper, an opening of a Aufsetztrichters facing region of a bag buckle, is also arranged spaced from the opening. This makes it possible, on the one hand, to put the still closed discharge spout of the big bag over the pipe socket and to connect it dust-tight with it and at the same time to achieve a flexible connection.

Preferred embodiments are disclosed in the dependent claims. Thus, the arrangement of one of the outlet opening of the pipe socket associated slider allows a dosage of the discharged bulk material and by the ability to connect the housing to a filter dusty air can be filtered. If necessary, the housing or the pipe socket can be supported on weighing elements. In addition to the emptying there is the possibility to install a smaller unit and a weighing unit.

The invention will be described below in an embodiment with reference to a drawing. The drawing shows an emptying device with additional elements.

An inventive emptying device for big bags or the like flexible container for bulk material comprises a bottom open and in the example quadrangular housing 1 , on the upper opening of a funnel 2 is attached, with the lower part of the Aufsetztrichters 2 with an opening 7 already inside the case 1 located. Below the opening 7 and centric to this is spaced a pipe socket 4 arranged. The pipe socket 4 is with a bracket 5 provided, the detachable in the housing 1 is arranged. In the case 1 are over each other several receiving points for the holder 5 provided so that the pipe socket 4 height adjustable and the distance to the opening 7 is variable.

The pipe socket 4 is in the top, the opening 7 of the stacking funnel 2 facing area of a sackcloth 9 surrounded so that the spout 8th of the big bag 3 over the pipe socket 4 slipped and fixed (the access is made by a door, not shown in the housing 1 ). This is the big bag 3 in the center in the hopper 2 discontinued and first the outer lacing of the spout 8th solved. The outlet opening of the pipe socket 4 is a slider 6 assigned, which allows a metered bulk material discharge. In a simple design, the slider 6 manually operated (handle 6a to slide 6 ).

In further training, it is possible, the housing ( 1 ) or the pipe socket ( 4 ) on at least one weighing element support.

When deflating, the repelling, dusty air between pipe socket 4 and inner wall of the housing 1 through the opening 7 escape. However, if this air is to be filtered, there is a connection 10 intended for a line to a dust filter.

Below the slider 6 closes to the case 1 preferably a discharge funnel 11 on, which can be provided with a Sackanhängevorrichtung and / or a discharge screw, not shown (but is also possible a loose filling in wheelbarrows oa).

A sack hitch can also be associated with a treadmill for mechanized bagging.
