DISCHARGE HOPPERS IN TANK VEHICLE WITH FLUIDISED BED

The invention is about an innovation regarding the flanged/bolted connection of the exit cones to the vehicle body which discharges semi-trailer silo vehicles used in transportation of powdered and granulose materials.

Silo semi-trailers are used for transportation of powdered and granulose materials. Due to the structural nature of these types of materials, exit cones are needed at discharge outlets of silos helping to discharge materials through pressure. Air, also called fluidization air, is blown into these systems through the inlet and the material is discharged from exit cones.

Connection of the elliptical exit cones to the silo tank body used as the discharge line of the silo semi-trailer vehicles used nowadays is made with welding technique. Due to work conditions and characteristics of the transported material, blockages occur over time in the gap that distributes air between elliptical exit cone and inner wall sheet metal. When these blockages are to be cleaned, the exit cones are separated by being cut from the welded area and the operation required for this process causes waste of time in the sense of serviceability.

The assemblies of the exit cones used presently on silo semi-trailer vehicles that are the subject of the invention are not welded on the body, but only the flange that is available in the cone assembly is welded to the body. Inner wall sheet metal, gasket and elliptical exit cone that are available in the cone assembly except the flange are fixed to the flange with bolts. In case of any blockages, bolts are removed and cleaning can be done. Thus, the exit cone becomes a service part, and in cases where its replacement or repair is required, this can be done thanks to its bolt connections.

The figures of the parts that are used for the invention to achieve its intentions are supplied in the appendix and these figures;

1 1 - Elliptical exit cone assembly,

The elliptical exit cone assembly (1 1 ) that is to be used on semi-trailer silo tankers consists of; flange (3), inner wall sheet metal (4), gasket (5), elliptical exit cone (6), O-ring gasket (8), solimar washer (9)u and connecting bolts (10).

In silo semi-trails (1 ), elliptical exit cone (6) is used under tank body (2) to discharge the material in the tank for preventing the material to stick and facilitating its fluidity.

Installation of the Elliptical Exit Cone Assembly:

First, the flange (3) is welded to the tank body (2). Respectively, the gasket (5) that provides air tightness, the inner wall sheet metal (4) where the solimar washers (9) are connected, gasket (5) and finally the elliptical exit cone (6) are connected to the flange (3) as an assembly with the help of connecting bolts (10). In addition to this assembly, an O-ring gasket (8) that provides air tightness is connected to the elliptical exit cone (6).

Thus, elliptical exit cone assembly (1 1 ) will become a spare part and will be easily replaced and repaired by removing the connecting bolts (10) in cases where replacement or repair is required.
