Abstract
In order to provide a treatment installation for treating workpieces that is of simple construction and enables optimised workpiece treatment, it is proposed that the treatment installation should include a treatment chamber and a conveying device, by means of which the workpieces are suppliable to the treatment chamber, are removable from the treatment chamber, and/or are conveyable through the treatment chamber in a conveying direction.
Claims22
A treatment installation for treating workpieces, in the form of coated vehicle bodies, wherein the treatment installation includes a treatment chamber and a conveying device arranged to supply the workpieces to the treatment chamber, remove the workpieces from the treatment chamber, and/or convey the workpieces through the treatment chamber in a conveying direction,
- wherein the treatment installation includes at least one circulating air module, wherein each circulating air module includes the following:
- a gas supply for supplying gas to the treatment chamber;
- and
- a gas removal arrangement for removing gas from the treatment chamber;
- and
- a distributor device for distributing a circulating air gas stream that is to be supplied to the treatment chamber over a plurality of inlet openings of the gas supply,
- wherein the distributor device is separated from the treatment chamber by a dividing wall, wherein all the inlet openings are made in the dividing wall.
The treatment installation according to 1, wherein
- a) the treatment installation includes at least one inlet opening for supplying gas to the treatment chamber and at least one outlet opening for removing gas from the treatment chamber, which are arranged on mutually opposing sides of the workpiece, wherein the at least one inlet opening and the at least one outlet opening are arranged on mutually different sides of a vertical workpiece transverse center plane;
- and/or
- b) at least one inlet opening and at least one outlet opening are arranged at a distance from one another that is at least approximately 60% of a total length of the workpiece, as seen in a workpiece longitudinal direction;
- and/or
- c) the treatment installation includes at least one inlet opening for supplying gas to the treatment chamber and at least one outlet opening for removing gas from the treatment chamber, wherein the at least one inlet opening on the one hand and the at least one outlet opening on the other are arranged on different sides of the treatment chamber in relation to a vertical longitudinal center plane of the treatment chamber;
- and/or
- d) the treatment installation includes one or more inlet openings for supplying gas to the treatment chamber and/or one or more outlet openings for removing gas from the treatment chamber, wherein the one or more of the inlet openings are arranged in one of two semi-chambers of the treatment chamber that are divided by a longitudinal center plane that runs vertically, horizontally or obliquely thereto, and/or wherein the one or more of the outlet openings are arranged in one of the two semi-chambers of the treatment chamber that are divided by the longitudinal center plane that runs vertically, horizontally or obliquely thereto;
- and/or
- e) the treatment installation includes a plurality of inlet openings for supplying gas to the treatment chamber and a plurality of outlet openings for removing gas from the treatment chamber, wherein the inlet openings on the one hand and the outlet openings on the other are arranged at least approximately opposite one another in relation to a diagonal plane, wherein the diagonal plane extends parallel to the conveying direction and substantially diagonally through the treatment chamber.
A method for treating workpieces in the form of coated vehicle bodies, wherein the method includes the following:
- supplying workpieces to a treatment chamber of a treatment installation;
- and/or
- guiding workpieces through the treatment chamber;
- and/or
- removing workpieces from the treatment chamber;
- wherein a gas supply of a circulating air module gas is supplied to the treatment chamber,
- wherein a gas removal arrangement of the circulating air module gas is removed from the treatment chamber,
- wherein, by a distributor device of the circulating air module, a circulating air gas stream that is to be supplied to the treatment chamber is distributed over a plurality of inlet openings of the gas supply, wherein the distributor device is separated from the treatment chamber by a dividing wall, wherein all the inlet openings are made in the dividing wall.
