DE2525703A1 - Dust remover for bulk goods trough - uses pivoted flap to close filling aperture - Google Patents

Abstract

The dust remover is for a receiving trough for bulk goods, esp. cereals and foodstuffs. The filling aperture (3) of the receiving trough (1) is closed by pivoted flaps (4). The flaps are pivoted by the weight of the bulk goods into an opening position corresponding to the amount of the goods. A suction conduit of a dust remover opens into the space of the trough below the pivoted flaps. The pivot axes (5) of the flaps are parallel and at right angles to the longitudinal direction of the trough. The flaps are positioned in pairs, so that the axes of a pair lie next to each other. When closed, the flaps slope downwards, and there are torsion springs to return them to the closed position.

Description

"Device for removing dust from an acceptance channel for bulk goods5 in particular Grain "The invention relates to a device for removing dust from a receiving gutter for bulk goods, especially for grain, seeds, animal feed and the like.

When tipping bulk goods, especially grain, seeds and Feed from vehicles in receiving gutters creates a lot of dust nuisance, which one has not yet been able to avoid in a satisfactory manner. Every now and then provided extraction systems do not lead to a satisfactory result, since the tilting process the material suddenly flows into the receiving gutter and a very high amount of dust is generated causes, for their complete suction an uneconomically large suction system would be needed.

The object of the invention is to provide a solution which is a effective elimination of dust nuisance with economically justifiable effort enables.

To solve this problem it is proposed according to the invention, that the filling opening of the acceptance gutter is essentially closed by pivoting flaps is that under the weight of the bulk good against a spring force in one of the Pivot the respective amount of the bulk material corresponding opening position and that A suction line poured into the acceptance space below the hinged flaps opens into a dedusting system.

Because of this training it is achieved that only relatively there are small openings in the filling opening of the acceptance gutter In each case only according to the amount of bulk material actually supplied, so that at these Opening cross-sections a relatively high vacuum when using a dedusting system There is a relatively small capacity, with the suction effect being targeted at the strongest there is where most of the bulk material is fed and, accordingly, the development of dust is the strongest.

It has proven to be useful to use the pivot axes of the pivot flaps horizontally and vertically to the longitudinal extension of the receiving gutter, in such a way that that then only relatively short parts of the acceptance gutter seen in the longitudinal direction need to swing open according to the respective length of the tipping vehicle.

It has also proven to be beneficial to use the hinged flaps to be arranged in pairs in such a way that the two pivot axes are closely adjacent to one another are. This results in between two adjacent swivel flaps at Open the same a funnel-shaped inlet, the inclination of which corresponds to the respective Bulk quantity varies. The swivel flaps can expediently be in the closed position already arrange a little inclined, so that the funnel effect is given from the start is.

It has also proven to be advantageous between the the edges of adjacent swivel flaps opposite the pivot axes in the closed position to leave an open gap so that the dedusting system can be used even with a small amount of bulk material work and suck off all dust that arises right at the beginning of the pouring process can be.

Finally, it is best to put the hinged flaps under the effect of these torsion springs pivoting in the closed position, as this results in a particularly simple and functional training.

The invention is shown below with reference to the drawing.

for example explained in more detail. This shows a device in FIG. 1 according to the invention in a vertical cross section and in Fig. 2 a Vertical longitudinal section along the line I-I of FIG. 1.

A receiving gutter 1 of an essentially conventional type, i.

basically funnel-shaped design with at its lower end provided drainage openings 2 and upper longitudinal slot-like filling opening 3, is in the area of this filling opening with pivoting flaps 4 arranged in pairs provided that poured around horizontally and perpendicularly to the longitudinal extension of the assumption directed pivot axes 5 against the action of torsion springs, not shown can be pivoted downward from the closed position shown in FIG. 1 into the open position are under the effect of the dead weight of one of a transport vehicle F tiltable bulk material.

In the closed position of the swivel flaps shown in FIG are between the edges of adjacent side flaps opposite the pivot axes 5 Column 6 is available and the hinged flaps are already somewhat in the closed position downwardly inclined in such a way that there is izichteriform between adjacent swivel flaps Fill openings result.

In the space of acceptance located below the pivoting flaps 4 Gosse 1 opens in Fig. 1 only schematically indicated suction line 7 of a fan 8, the pressure line 9 of which to a dust filter 10 is more conventional Type leads.

It can be seen that due to the training described in already Before pouring the fan 8 switched on, a negative pressure is present at the columns 6 is through which the first dust that arises is sucked off immediately when the pouring begins and that depending on the increasing pouring process and the resulting further Opening the column 6 as a result of the pivoting flaps 4 being pivoted downward, an increased Dust extraction takes place directly at the point of origin, whereby of special What is important is that a loss of vacuum in the remaining area of the assumption would not pour can arise, i.e. the suction effect of the dedusting system is targeted only on the Points are directed at which dust accumulation occurs according to the bulk, so that with a relatively small dimensioned and thus economical to operate Dedusting system can be managed.

Finally, it is of particular advantage that the Training allows you to also retrospectively use existing acceptance gutters a device according to the invention, namely by simply a finished Installation kit of mon in a common frame.

oriented swivel flaps in the longitudinal slot-like filling opening one such acceptance gutter installed, as well as one in the space below the filling opening Suction line is connected to a dedusting system.

Of course, the embodiment described is in many ways to change without departing from the basic idea of the invention. So could the arrangement of course, the swivel flaps also take place in such a way that they move away from their swivel axes all extend in one and the same direction, However, the described training particularly advantageous due to the resulting funnel effect. Also could instead Torsion springs naturally attack tension springs on the swivel flaps and the like. more.
