Tube switch for pneumatic conveying systems to order

of granular material

Pneumatic! Conveying systems consist of a GeToIaSe _5, a sluice 5 conveying line, changeover switch and separator. They are used in a wide variety of industries for the conveyance of granular _: good. .- """.■" .. ".

With pressure blowers, the granular material is fed into the pipeline through a mechanically operating sluice or according to the injector principle, and is blown by the wind flow through the pipeline Ms to the delivery point ^.

In order to feed different delivery points, the pipeline can be branched off «, At the branching point a pipe switch or a pipe switch must be installed * ^or a so-called * Y-piece.

The tube switch j in the known 2- or 3-way type, is a flap box with pipe connection pieces ₉ - which run at as flat an angle as possible.

Modern farms can hardly do without pneumatic conveying devices for grain »In this case, see the blower "grain blower" and is offered for different hourly outputs with different motors »The pipeline parts are handy and should be easy to lay »An den Ter-_ binding parts are quick-release fasteners or plug-in connections with Rubber seal usual. Here, too, the moved grain has to pass through various stations before it is finally stored »The usual Tube switches or tube switches are labor-intensive flap boxes, consist of many parts and are therefore very expensive high.

The control was now based on the task * much "easier, To develop lower-priced Kohrumsehalter in shell construction. "-

With the 2-way in-line switch, the task can be solved easily, by installing a flap in the rounded flap box, the front part of which is rounded =. This closes the flap tight in both band positions, the front part adapts to the curve of the flap box and an inserted seal takes over the exclusion of air.

In the construction of the 3-way tube switch in shell construction the simple switch-over flaps, which are rounded in the front part, can no longer be used. If you choose the outer conveying routes (left or right) then both flaps are on top of each other, and there the front part of the. If the flap is rounded in the shape of an arch, the pipeline can no longer be sealed the outer paths on ο If you choose the middle branch, then both changeover flaps close, as rounding meets rounding, completely off. According to the invention, a switchover flap is proposed, whose front part made of elastic material, such as. 1. Rubber, plastic materials or Pederstahl are made up »■. "

The special features of the new Rohrumsehalters emerge from the following description with reference to the drawing, which some shows the possible embodiments of the invention.,

Pig. 1 represents a 2-way in-line switch in shell construction dar «, Sr consists of two half-shells 1, the one built into them Reversing flap 2, the deflectors 3 and the attached Pipe sockets 4 and 5. Close to the axis of the switchover flap 2 is an inserted ,, Double triangle bent at an acute angle 6 »

The price increase consists of the rounded shell construction of the hinged box - as shown in section A - B, whose rounding corresponds to the pipe diameter. The pipe socket 4 and 5 can without special Transition pieces can be attached to the shells.

The bowl is very stable due to the curves, so that the sheet metal thickness is reduced compared to the previously common flap boxes and special reinforcements are not required »

shows a 3 * -way tube switch in shell construction. The half-shells 1 form the flap box? in which the deflectors J are permanently installed. As a result of the rounded shells, the pipe sockets 4 and 5 can also be attached here without special transition pieces. The double triangles 6, bent at an acute angle, lie between the pipe sockets. The situation before going into an external pipeline is shown on an enlarged scale in the detail "E""Meetsthe". Top. 8 of the switchover flap 7 on a flat surface as in this example on the second switchover _{flap of the 3-way connector s,} then the elastic, rounded part of the flap bends and adapts to the surface. The solid _s rectangular part 7 seals the pipeline when it hits the surface. :

The view in the direction ¹¹ O "applies to both tube change-over switches and shows the exact shape of the changeover flap 2 or 7? Whereby only with the 3-way, tube change-over switch the front rounded part 8 is made of elastic material Switchover flap 2 or there is a seal 9 »The shift lever 10 is held in the known manner by a locking device in the connection points, which is not shown in" the drawing and will not be explained further. _: ■ ■■. ■
