Definitions
- the invention relates to an exhaust hood as defined in the preamble of claim 1.
- Such a hood is known from FR-A-2311600 and FR-A-2490112.
- the known exhaust hood removes much air from the zinc-plating plant in order to drain gases set free during the zinc-plating process as much as possible. Therefore the capacity of the air removing means connected with the hood has to be correspondingly high. This is particularly inconvenient when the air to be removed has to be filtered.
- the invention provides an exhaust hood improved in this respect, which is characterized as defined in claim 1.
- a further development of the exhaust hood embodying the invention is descriped in claims 2 to 4.
- a zinc-plating hall 1 as shown in the Figs. 1 and 2 comprises a zinc-plating line comprising in a conventional manner a degreasing bath, a plurality of pickling baths, a flux bath, a drying station 2, a zinc-plating station 3 and a delivery station 4, which is a cooling station.
- Fig. 1 only shows the latter three stations.
- the drying station 2 are provided the required drying means, for example, ventilators 5, which dry the objects 7 preferably by hot air.
- the zinc-plating bath 6 is provided with heating elements 22. This bath is surrounded by a stationary lower hood element 8. Below the roof 9 of the hall T a stationary top hood element 10 is provided atthe zinc-plating station 3. Between the lower and top hood elements 8 and 10 can be arranged a displaceable hood element 11 in which lifting means 12 of a lifting tool 13 are arranged.
- the lifting tool 13 comprises a carriage 14 travelling on rails 15. To this carriage 14 is fastened the hood element 11, for example, by welding.
- the travelling crabs 30 of the lifting means 12 are movable along rails 38 of the carriage 14 arranged in the interior of the hood element 11.
- the travelling crabs 30 are provided with winches 16, lifting cables 17, pulleys 18, hooks 19 and a lifting frame 20 to which the objects are fastened.
- the delivery station 4 is provided with a cooling bath 21.
- the lower hood element 8 has an inner jacket 23 and an outer jacket 24, between which a gallery is left, which is accessible through doors 29 to persons to scrape slags with the aid of a scraper 39 from the surface 26 of the zinc-plating bath 6 immediately before the zinc-plated objects 7 are lifted out of the zinc-plating bath.
- the lower hood element 8 has, apart from transparant sash windows 25 further transparant windows 31 in the outer jacket so that from the cabin 34 suspended by means of rods 33 to the carriage the crane driver can observe the manipulations of the objects 7.
- the crane driver can look below the hood element 11.
- the exhaust hood embodying the invention operates as follows:
- the sash windows 25 are lifted for scraping slags. Then the zinc-plated objects 7 are lifted from the zinc-plating bath 6. The inflatable sealing strip, if any, is in the meantime exhausted. The objects 7 together with the hood element 11 are brought to the delivery station 4, where they are moved out of the hood element 11 and unhooked from the lifting frame 20. Finally the lifting tool is driven back to the drying station 2 for treating further objects 7.
- the exhaust hood is an integral unit. Inside the hood 40 are arranged the lifting means 42. The exhaust hood 40 communicates through a hose 41 with an outlet channel 43 so that the exhaust hood 40 can move between the drying station 2 and the delivery station 4, for example, since it is arranged on a carriage 44. The objects 7 are then located at the drying station 2 in a cellar 45.
