The invention relates to a barrier and to a continuous annealing furnace comprising a barrier. The barrier (10) comprises at least a frame (36, 37), a actuating element (18), a gate (12), a first lever (14) being pivoted at said frame (36, 37) on a first rotational axis (20) and a second lever (16) being pivoted at said frame (36, 37) on a second rotational axis (21). Said gate (12) and said actuating element (18) are hinged at said first lever (14) opposite said first rotational axis (20) as well as said gate (12). and said actuating element (18) are hinged at said second lever (16) opposite said second rotational axis (21) for moving said gate (12) in a moving direction (68) by actuating said actuating element (18). In accordance with the invention said first and second lever (14, 16) are arranged axially symmetrical in respect to said moving direction (68) at said frame (36, 37). The continuous annealing furnace (26) comprises at least two muffles (28, 30) being connected by an intermediate module (32). Said intermediated module comprises said barrier (10) for isolating a gap (34) constructed in said intermediate module (32).
Abstract:
The invention relates to an apparatus and process for the prodution of polycrystalline silicon for photovoltaic applications. The apparatus is characterised in that it comprises of multiple chambers, preferably three(1, 2, 3), arranged longitudinally one after the other and equipped with: gas immission and extraction means; means for guiding (7) and moving the crucible (6) containing the silicon-based material; insulation and temperature control means; heating means; air-tightness means (8) for each chamber. One of said chambers constitutes the furnace of the apparatus and comprises an area (4) in which the smelting of the material contained in the crucible (6) is carried out, said furnace being equipped with heating means and bearing a heat-stable pedestal (5), suitable for moving the crucible vertically and thus for introducing it into, or extracting it from the smelting area (4), respectively.
Abstract:
Печь для обжига керамических изделий относится к области техники, а именно, к обжиговым печам непрерывного действия и может использоваться для термической обработки строительных керамических изделий, в частности, пустотного кирпича и блоков. Печь для обжига керамических изделий состоит из основного канала (2), который заполняется изделиями (3) и циркуляционного канала (4) с устройствами перемещения газа (6), которые обеспечивают его циркуляцию путём отбора газа из основного канала (2) и возврата его в основной канал (2) с противоположной стороны. При этом печь для обжига разделена на секции перегородками с отверстиями. Также в перегородках между секциями дополнительно выполнены направляющие элементы - заслонки (11) для создания потока газа между секциями. А в циркуляционном канале (4) дополнительно установлен теплообменник (12), который оборудован вентилятором.

Abstract:
Die Erfindung betrifft einen Ofen zur Wärmebehandlung einer Vielzahl von Gegenständen. Der Ofen umfasst ein Tragegerüst (10), das als ein dreidimensionaler Rahmen ausgebildet ist, eine langgestreckte Heizkammer (12), die vertikal oder horizontal in einem zentralen Bereich des Tragegerüsts (10) angeordnet ist, und eine Mehrzahl von langgestreckten Brennkammern (14), die vertikal oder horizontal innerhalb des Tragegerüsts (10) angeordnet sind. Der Ofen umfasst weiterhin ein Heizelement (28), das der Heizkammer (12) zugeordnet ist, und wenigstens ein Gebläse (24) zum Erzeugen eines Luftstroms von der Heizkammer (12) zu den Brennkammern (14). Die Brennkammern (14) sind zum Aufnehmen der zu behandelnden Gegenstände vorgesehen. Das Tragegerüst (10) ist zum Abstützen der Heizkammer (12) und der Brennkammern (14) vorgesehen. Weiterhin betrifft die Erfindung eine Ofenanlage mit einer Vielzahl solcher Öfen.
Abstract:
A heat treatment apparatus comprises heat treatment chambers into which an object is transferred and heat-treated. At least one set of adjacent heat treatment chambers the temperatures of which are mutually different are connected through a heat-insulating structural member. As a result, the heat conduction between the heat treatment chambers (for example, muffles) is suppressed, and consequently the heat loss caused in the heat treatment chambers are decreased. Therefore the required heat input energy for predetermined heat treatments are significantly reduced without influencing the quality of the object and the yield.
Abstract:
An apparatus and a method for treating an object material containing a heavy metal and a noxious organic halide, and a method of treating soil. The treating apparatus is provided with an air-tight door (115b) and a retort (115c) as interfaces for taking out to the outside a discharged gaseous material containing an evaporated material from an object material to be treated which is heated under vacuum in an air-tight chamber (103) while maintaining the conditions such as temperature and pressure in the air-tight chamber, the retort (115c) shutting off the air-tight door (115b) in an opened state from the air-tight chamber (103) when the retort is inserted into a first opening (103b) of the air-tight chamber, thus preventing condensation of the discharged gaseous material on the air-tight door.
