Meyer, Wilhelm
Abstract
A system for the hot stamping of workpieces comprises a furnace installation (8), in which workpieces (4) can be heated to a forming temperature, and a forming installation (12), in which the heated workpieces (4) can undergo forming. By means of a transfer device (10), workpieces (4) can be transferred from the furnace installation (8) to the forming installation (12). The transfer device (10) is arranged in a transfer space (36), which is delimited at least in certain regions by a housing (38) and largely bridges the space between the furnace installation (8) and the forming installation (12). Also provided is a method for the hot stamping of workpieces (4).
In the context of a method for operating a surface treatment plant (12), resulting overspray in a coating booth (10) is taken up by an air flow. The air flow loaded with overspray is conveyed as exhaust air flow to at least one separation unit (44) in which overspray is separated out. In a supply region (64) upstream of the at least one separation unit (44) and/or in an internal space (48) of the at least one separation unit (44), a filter aid having a separation aggregate state is added to the exhaust air flow and forms, with the overspray, a separation mixture which is separated in or at the at least one separation unit (44). The filter aid used is solid or liquid in the separation aggregate state. In the at least one separation unit (44), conditions are established in which the filter aid transitions from the separation aggregate state into a gaseous aggregate state such that the gaseous filter aid can separate from the separation mixture.
A thermal post-combustion unit with a combustion chamber having a combustion space to which exhaust air can be supplied, having a burner for heating the combustion space, whereby clean air is produced, having an inlet for exhaust air and having an outlet for clean air. A flow path connects the inlet to the combustion space. Exhaust air can be heated by a heat-exchanger system. The flow path comprises a first, second and third flow section, wherein the first flow section is connected to the inlet and the exhaust air flows from the third flow section to the combustion space, wherein the flow sections connect to one another at diversion ends so that the exhaust air flows through two successive flow sections with different flow directions. Heat-exchanger pipes extend at least inside the first and the second flow section or at least the first and the second flow section extend inside heat-exchanger pipes.
