DE1815066B2 - Bulk material silo discharge - has unions for porous hoses on compressed air buspipe at cone bottom - Google Patents

Abstract

The silo discharge is for handling material in bulk, having a cone tapering towards the bottom, round which are mounted a series of porous hoses running in the direction of the cone axis, each stretched onto a flat spreader strip and connected to a common compressed-air supply pipe. A round compressed-air union boss (18) is provided for each of the hoses (26, 27, 28) on a common annular buspipe at the bottom of the cone and extending upwards. The hose ends fit over the bosses. The lower and tapered ends of the spreader strips are fixed to the bosses between them and the wall, and these strips extend nearly to the upper ends of the hoses where the hoses are secured flat to the cone wall.

In the drawing, 1 denotes an outlet cone that tapers only slightly downwards, which opens into an outlet opening 3 surrounded by a flange 2 below an outlet 4 tapering much more sharply downward by means of a flange 5 below Interposition of an intermediate ring 6 screwed on The outlet cone 1 closes at the bottom to one Silo container, not shown, and forms a tapered drain for the debris or dust, the continues through the inner opening of the intermediate ring 6 and finally the strongly tapering outlet 4 and opens into a nozzle 7 for connecting a pneumatic debris or dust conveying line. Of the Outlet 4 has an outer wall 8, which is shell-shaped and an inner wall 9, which Is conical and is porous. The space 10 between the two walls 8 and 9 can be connected to a compressed air supply line by means of a connector 11. The one through the inner porous wall 9 formed cone limits the outflow and opens via a bend 12 in the Connection 7. A compressed air nozzle 13 also opens into the bend 12, which nozzle extends into the axis of the connection 7 is directed to accelerate the flow of material in the elbow. This nozzle 13 is also on a Compressed air line can be connected. The intermediate ring 6 has an inner compressed air ring line 14 which extends around the Extends the entire circumference and can be connected to an outer compressed air line via a connector 15. Of this Ring line 14, which up and down by means of sealing rings 16, 17 against the flanges 2 and 5 is sealed pressure-tight go to the type of elbows formed compressed air nozzles, from which one, namely the compressed air connection 18 in F i g. 1 is visible. Other such compressed air connections are, such as can be seen from Fig.2, distributed over the entire circumference The view according to FIG. 2 is mirror-symmetrical to the mirror symmetry line 39 shown, from which it results that a total of eight such compressed air nozzles are arranged equiangularly distributed over the circumference.

The outlet 19 of the pressure / air nozzle 18 is directed upwards and widens towards the mouth 19 there. The mouth is as shown in Fig.2.

You can't borrow one to cover these porosities either! ' Use a hose that has no porosity in the rear area. The tube 20 is clamped at its upper end by means of a screw clamp 24 and at the same time on the inner wall of the discharge cone. screwed. whereby the upper Spreizstreifenen de is attached indirectly to the cone wall.

The spreader strip. on which the tube 27 is spread is shown in dashed lines in FIG. From the mouth, the hose no longer spreads, because in this area it is spread there by the mouth of the nozzle 26 to the desired circular cross-section.

If bulk material is to flow away, then a pneumatic delivery line is connected to the nozzle / and compressed air is connected to the nozzle 13, 11 and 15, so that this compressed air flows over a wide area from the porosities of the hoses and penetrates the flowing material from bottom to top and at the same time loosens up and at the same time forms an air cushion as a sliding surface!

In such a case it is not necessary to make the connection between Spreading strips 21 and the associated compressed air connection 18 or the corresponding remaining ones To loosen connections of the other loosening agents in order to remove the intermediate ring 6 completely. But you can also use rigid expanding strips and releasably attach them to the compressed air connection. How this can be done, for example, will now be explained with reference to FIG Attachment point of a modified embodiment in the same view as in F i g. 1 the Attachment point for the strip 21 is shown on a larger scale
