Agitator for bituminous paste as road building material or road patch.

The invention relates to - from OE patent 359 ^ .118

C bzM -thermobiasfisdi £

starting out - an agitator for bituminous) pulp as road building material bsw, street patchwork, consisting of a shaft that rotates in a housing and carries agitator blades. What has been invented is characterized by the fact that, in addition to agitator blades, one or more heating elements are stationary are arranged, preferably in such a way that a single heating element is annularly concentric around the shaft extends around, e.g., one containing an electrical winding Heating ring.

The purpose of this pulp heater or pulp cooker is that the road building material is thinner than before, so that for Mixing requires much less power than before. Such a result is a great asset in repairing of damaged, pierced road sections or sections of road in need of renovation.

The drawing shows two exemplary embodiments schematically by means of cross-sections. the

Fig. 1 illustrates a direct electric cylinder coil heating source arrangement, while the

Pig 2 an indirect electro-heated type Reflects the liquid cycle. the

Pig 3 shows a variant with thermosyphon heating fluid circulation.

The main parts of the device are the agitator blades 3 rotating in a housing and supported by the gearwheel 10 driven shaft 2, around which the radiator 4 extends concentrically. This radiator stands up one or more pillars or struts 5 »which the Electrical supply lines 6 to the heating coil (Pig 1) or the heating fluid circulation channels 7 (Pig 2) contain. Latter If necessary, completed with a fluid circulation pump.

The heating element (s) are / are arranged between agitator blades (Pig 1 and 2). The heating coils of the electric heater are denoted by 11. According to Pig's radiator, a hot liquid flows through it, ring-shaped boiler (indirect!) heating) in contrast to the Direct heating according to Pig 1, in which the heating coil is directly in the Boiler is embedded.

The inventive ideas ensure a relatively much "cheaper operation of the pulp mixer compared to known. Advised

The Mg 3 sets with oil or a heat transfer fluid Filled basin 12 in which the TJ-shaped heating coil 13, 14, known per se, is located. In the a burner blows a jet of heat in at one end, the other end H opens into the exhaust port. The channels 15, 16 are elements of the circulation system. The wave is supported by means of ribs 17 as parts of bearings on the housing.

Claims (5)
