Embodiment Construction

[0024] The device for tempering bulk material shown in FIG. 1 has an upper buffer section 1 , a central heat exchange section 2 and a lower discharge section 3 . The segments 1 , 2 , 3 each have a circular cross section. The shell-shaped, substantially closed buffer section 1 is provided with an upper supply connection 4 for conveying the bulk material to be tempered.

[0025] The heat exchange section 2 has a housing 5 , in an interior 6 of the housing, mutually parallel heat exchanger tubes 7 are arranged at a distance from each other. That is, the inner cavity 6 is a heat exchange cavity.

[0026] Adjacent to the discharge section 3 , a supply connection 8 for the heat transfer fluid opens into the interior 5 of the housing 5 of the heat exchange section 2 . Adjacent to the damping section 1 , a discharge connection 9 leads out of the interior 6 of the housing 5 . Deflector plates 10 are mounted in the interior space 6 at a distance from each other transversely to the lo...

Abstract

The invention relates to a device for adjusting the temperature of a loose material (20), comprising a heat exchange section (2). A buffer section (1) for the loose material (20) is located at front of the heat exchange section, while a material discharge section (3) is located behind the heat exchange section. A heat exchanger tube (7) is arranged on the heat exchange section (2) along the gravity direction. Besides, a feeding device (8) and a discharging device (9) for carrying a heat fluid are communicated with the exchange section (2).

Description

technical field [0001] The invention relates to a device for regulating the temperature of loose materials. Background technique [0002] Said temperature adjustment can be heating or cooling of the bulk material. Simultaneous drying can also take place if heat is supplied to the bulk material, which in turn is a carrier of moisture. The moisture is removed by means of the gas supplied. Bulk material in the context of the present invention is understood to be free-flowing loose material such as fertilizers, plastic granules, plastic powder or also foodstuffs such as sugar. [0003] When heating and cooling the bulk material, the heat transfer from the bulk material to the heat carrier fluid and vice versa is limited due to the low thermal conductivity of the bulk material. For tempering the bulk material, shaft coolers are currently used, such coolers are known, for example, from EP 0444338 B1 in the form of a plate heat exchanger. The bulk material flows between at leas...
