Definitions
- the invention relates to a bulk container, according to the preamble of claim 1.
- Such a bulk container is known from DE 344 691 C.
- On the emptying opening has a downward-pointing nozzle inside crowned surface in cross section required what an elaborate production means.
- the container is still not a complete seal possible.
- Another bulk container with discharge opening and swiveling Opening flap is from EP 0 142 003 B2 - there as a batch mixer - already known. It is envisaged that the between the first Narrow side and the outside of the opening flap formed angle is an acute angle with the aim of being open and accordingly flap hanging down on this upper first narrow side no bulk goods should be able to remain because of this slant Narrow side slips. In one embodiment, this Previous publication, this angle is chosen so that the between the first narrow side of the opening flap and the corresponding housing wall joint in the closed position approximately runs horizontally and its cross-section approximately to the middle of the Axis of rotation is directed.
- the bulk goods container is also intended for bulk goods be suitable that contain powdery or dusty components or consist of such.
- the bulk container is for the majority of bulk materials, especially those that are powdery or contain dusty constituents or from such exist, suitable.
- the seal gradually as the counter surface closes is under increasing pressure because the counter surface and the sealing surface is not at a right angle in the sense approach that one surface after a touch the seal overall compressed, but because of the oblique and gradual approximation also the compression of the seal in the course the pivoting increases in the closed position.
- the seal will because of this arrangement not directly from each other approaching surfaces compressed, as is the case with the seal.
- EP 0 142 003 B1 is provided, but it can even be on the Seal adhering material first through the closing process be scraped off, the further course of the closing movement the seal increasingly from the scraping counter surface is acted upon and compressed.
- the pressure force transverse to the closing direction and not in the closing direction This means that practically no bulk material can adhere to the sealing surface and impair the sealing effect. Practically takes place at Seal an automatic self-cleaning of the sealing area.
- the oblique first narrow side of the opening flap can, in cross section seen with the inside enclosing an acute angle, its edge when pivoting in the closed position as a scraper serves at least on the counter slope.
- the slant of the first narrow side that with the outer surface encloses an obtuse angle, so it can go to the inside be continued that there is a corresponding acute angle is formed, the edge of which is suitable as a scraper of bulk material is, possibly in the area of the emptying opening on its edge or Narrow side stuck.
- the narrow side adjacent to the opening flap is an advantage because the Pinching foreign objects at this point in parallel running edge of such an opening flap corresponding to the The gap of this edge would gap significantly further.
- An embodiment of the invention can consist in that the parallel to the first narrow side close to the swivel axis second narrow side of the opening flap one at an angle to Outside of the flap, especially the circle has an approximate cross-sectional shape, that of it when pivoting is described about the pivot axis, and that that of the second Counter slopes at the narrow side in the closed position Emptying opening or one at another opening flap has a suitable, approximately parallel cross-sectional shape. Consequently can also on this second narrow side remote from the pivot axis jamming of bulk goods can be prevented, which is a would have significantly less impact, but still one Leakage could result. Also in the area of the second narrow side can be ensured that evt1. adhering bulk material at Closing process is automatically stripped at least to the extent that the closing process itself is not hindered.
- the second narrow side with the Outside of the opening flap - seen in cross section - one blunt and point with the inside of the opening flap Includes angle and that between the narrow side and the The inside edge serves as a scraper. While closing Such a bulk container is first the inner edge of the first narrow side its stripping function begin while stripping on the second narrow side during the very last part of the closing movement, so that those that may result from such stripping operations Resistances do not occur simultaneously.
- a particularly effective and for stripping bulk goods on the one hand and the tightest possible closure on the other favorable arrangement in a particularly simple embodiment can be that the cross section of the first narrow side and / or the second narrow side of a tangent to the respective swing circle or swing cylinder of these narrow sides corresponds to the pivot axis of the opening flap and the Narrow side (s) is (are) essentially flat.
- Such cases only need only one level overall To be trained on narrow sides, but on which nevertheless inventive advantageous stripping effect can be generated.
- the narrow side (s) and / or the counter bevel (s) has a polygonal shape, and for such polygonal shape of their cross-section at least two planar areas at an angle to one another can be provided, between which an obtuse angle is enclosed.
- the seal on the outside of the container and its sealing surface approximately in continuation of the Counter slopes of the discharge opening is arranged and the opening flap in continuation of its narrow side on the outside an approximately parallel running to the narrow side, with a blunt in cross section Angle-forming stop bar to interact with this seal has, the pressure surface facing the seal in cross section seen in the position of use in particular somewhat obliquely to the Sealing surface of the seal runs and the seal in this Use position somewhat suppressed.
- the bevel of the printing area is chosen relative to the sealing surface of the seal so that the greatest compression of the seal at the top edge region facing away from the container, that is, in The closed position takes the pressure between the pressure surface and the sealing surface seen from the container with increasing distance from its Outside too. This arrangement enables the closing process the sealing surface first shabby and then more and more with it Pressurize, but without two in the area of Seal directly approaching and pinching the seal Need surfaces so that no bulk material on the seal, impairing them, can be pinched.
- the seal can be designed as a sealing strip, the sealing surface with a relaxed, non-loaded seal, i.e. when the Opening flap is in the open position, runs essentially flat and this sealing strip can preferably from the sealing surface and one of these neighboring displacement areas entirely or partially enclosed by a support housing.
- the seal can not avoid, but is replaced by the sliding and thereby increasing pressure through the pressure surface of the Stop bar is gradually compressed and can be adjusted accordingly exert a good sealing effect.
- the support housing together with the seal adjustable with this transverse to the longitudinal extent of the seal and adjustable, especially towards the opening flap is adjustable.
- the The seal can always be moved into a position in which an optimal sealing effect is achieved.
- from assembly easier from the start because the seal with your Support housing pre-assembled and then on the opening flap and their counter surface can be adjusted.
- the emptying opening can be shaped appropriately and that in the area this approximately at right angles narrow sides Seals are provided on the outside on the edge of the emptying openings can be, which with counter surfaces inclined relative to them in cooperate in the sense that when you close the opening flap are increasingly compressible by this relative inclination.
- these can also run transversely to the pivot axis Narrow sides the beneficial sealing effect and self-cleaning the seal can be achieved through the corresponding narrow sides.
- a container designated as a whole with 1 serves for receiving and in the exemplary embodiment also for mixing bulk material and is in in this case approximately drum-shaped or cylindrical.
- These opening flap (s) 2 (18) practically form a lower one Wall area of the container 1.
- the Container 1 instead of such an approximately cylindrical container 1, the Container 1 but also any other shapes, for example have the shape of a stand silo.
- the respective opening flap 2 can be pivoted about a pivot axis 3 and has a substantially rectangular shape in the exemplary embodiments Shape, being due to the cylindrical shape of the container 1 in addition also has a curvature in one direction.
- the pivot axis 3 is bided or stored by hinges 4.
- the Pivot axis 3 near or parallel first narrow side 5 of the Opening flap 2 is formed obliquely in its cross section, that is between itself and a surface of the opening flap 2 one of Includes a 90 ° angle.
- the container or emptying opening has a counter bevel 6 that fits so that the first Narrow side 5 of the opening flap 2 and the counter bevels 6 of the edge 7 of the emptying opening in the use position at least in some areas run approximately parallel to each other, i.e. the narrowest possible joint form.
- the Edge 12 when swiveling in the closed position as a scraper serves at least on the counter slope 6.
- the Fig.4a is very clear that when closing the opening flap 2 whose narrow side 5 with the edge 12 first to the Counter-sloping 6 arrives and any bulk material located there scrapes and scrapes, just like the opposite slopes on the Narrow 5 located bulk goods can strip, so that in Closed position according to Fig.3 between the narrow side 5 and the Counter bevels 6 practically no more bulk goods can be present and especially with this closing movement at this point none Bulk material can be pinched, which affects the closing movement could prevent.
- the second narrow side 15 thus closes with the outer side 8 of the Opening flap 2 also a blunt and with the inside 11 an acute angle.
- This is Counter bevels 17 on a further opening flap 18 is only to ensure that when closing both opening flaps first the flap 18 and then the flap 2 are closed so that the located on the second narrow side 15 of the opening flap 2 Scraper edge 12 can take effect.
- the bulk material container shown in the exemplary embodiments 1 has one (Fig. 6 and 7) or two (Fig. 3 and 4) opening flaps 2 and 18, which are opposite the discharge opening by means of at least one Seal 19 are sealed.
- the seal 19 is a sealing strip formed and seals the joint between the closed opening flap 2 and counter bevels 6. It is the fugue and the Counter bevels 6 adjacent to the outside of the container 1 arranged, but could also on the outside of the opening flap 2 and / or 18 can be provided.
- Their effective sealing surface 20 runs in cross section in Area of the respective swivel circle 9 and 16 or swivel cylinder, the respective narrow side 5 and 15 of the opening flap 2 or 18 and a stop bar 21 adjacent to these narrow sides describes, the sealing surface 20 or that in the embodiment on the stop bar 21 counter surface 22 this respective Swivel circle 9 or 16 or the corresponding swivel cylinder touches or cuts at an acute angle, which is particularly the case in Fig.4a and 4b is made clear.
- seal 19 on the outside of the opening flap 2 and 18 may be provided, but it is in the embodiment arranged on the outside of the container 1 and its sealing surface 20 is in continuation of the counter slope of the discharge opening, which has the advantage that the stripping edge 12 of the first and the second narrow side also the sealing surface 20 automatically at Closing cleans.
- the opening flap 2 and 18 continues in its narrow sides 5 and 15 on the outside the already briefly mentioned, approximately parallel to the Narrow sides, with a blunt in cross section Angle-forming stop bar 21 for interaction with the seal 19, whose seal faces, in the following as a pressure surface 22 designated counter surface seen in cross section in the use position runs somewhat obliquely to the sealing surface 20 and the seal in the use position, i.e. in the closed position, something with pressure in Applied and displaced circumferential direction of the container.
- the sealing surface 20 of the seal 19 designed as a sealing strip runs in a relaxed, unencumbered situation in the essentially flat and this sealing strip is - from the sealing surface 20 and one of these adjacent displacement area 24 - enclosed by a support housing 25, so kept well chambered.
- a support housing 25 for the seal 19 together with this transverse to the longitudinal extent of the seal 19 and thus also in the transverse direction to the narrow sides 5 and 15 adjustable and adjustable and especially towards the Opening flap 2 and 18 is adjustable, in which the retaining screws 26 solved for the support housing and this, for example shifted in the direction of appropriately arranged elongated perforations can be.
- FIG. 5 shows the closed position in the left part, in which the counter or pressure surface 22 one on the outside of the Opening flap located stop bar 21 on the seal 19 compresses the sealing surface in an oblique direction, while in right part of Figure 5, the opening flap with its stop bar 21 and their counter surface 22 already in the open position is pivoted that the seal 19 and its sealing surface 20th are released.
- the bulk container especially for building materials or building material mixtures has at least one about an approximately horizontal pivot axis 3 pivoting, usually rectangular opening flap 2 for Closing a lower discharge opening.
- the pivot axis 3 is located near or parallel to a first narrow side 5 of this opening flap 2 and this first narrow side 5 is over at least a part of their cross section arranged obliquely, so that they with the surface of the outside 8 of this opening flap 2 forms an obtuse angle.
- the container or emptying opening has a matching counter bevel on the corresponding edge, so that the first narrow side 5 of the opening flap 2 and this Counter bevels 6 of the discharge opening in the use position at least partially parallel to each other.
- the obtuse angle on the first narrow side 5 is chosen so that the course this oblique narrow side 5 on the from this narrow side Opening and closing described circle 9 about the pivot axis 3rd is at least approximate.
