Embodiment Construction

[0032] For example, figure 1A pelletizing plant 1 for producing ore pellets using the present invention is shown. At a supply station not shown below the hood 2 , the bulk material is filled onto trolleys 3 forming an endless chain of trolleys called a “travel grid” 4 . Below the hood 2 the bulk material transported on a trolley 3 passes through a plurality of heat treatment stations in which it is eg dried, preheated, fired and finally cooled again. At the processing station below the hood 2, the traveling grid 4 is guided on the top section 5 of the continuous conveyor 6, wherein the track rollers 7 of the trolley 3 are guided between the inner curved rail guide 8 and the outer curved rail guide 9 guide. The drive of the travel grid 4 is achieved by means of a drive or lift wheel 10 formed as a gear wheel and whose tooth gap (gap) 11 engages a pressure roller 12 of the trolley 3 (cf. Figure 6 ).

Abstract

Equipment for handling bulk material such as iron or zinc ore pellets or sintered material in which the trolley (3) is mounted in an endless chain by lifting wheels (10) and lowering wheels on rails (8,9) Being conveyed continuously, the outer curved link ( 16 ) of the rail ( 9 ) can be opened in the region of the bottom section of the lifting wheel ( 10 ) in order to remove the trolley ( 3 ) from the chain. In the area of ​​the top section of the lifting wheel (10), the outer curved link (20) of the rail (9) can be opened in order to insert a new trolley (3) into the chain. In the area of ​​the bottom section of the lifting wheels (10) a removal switch (30) is provided, by means of which the trolley (3) can be removed from the chain, while in the area of ​​the top section of the lifting wheels (10) In the area of ​​, a supply switcher is set up, through which the trolley (3) can be moved into the chain.

Description

technical field [0001] The invention relates to a device for changing a trolley in a plant for handling bulk material, such as iron or zinc ore pellets or sintered material, wherein the trolley is moved between The rails are continuously conveyed in an endless chain, where in the area of ​​the bottom section of the lifting wheel the outer links of the curved rails (external curved links) can be opened and the trolley or similar can be removed from the chain by means of a transfer device and wherein in the region of the top section of the lifting wheel the outer curved link of the rail can be opened and a trolley or the like can be inserted into the chain by means of a transfer device. The invention also relates to a method for exchanging a trolley in such a plant. Background technique [0002] In a pelletizing or sintering plant, the bulk material to be processed (for example, iron ore or zinc ore) is filled onto trolleys forming an endless chain of trolleys also called a t...
