Problems solved by technology

However, this requires replacement of all pallet trucks, increasing conversion costs
In addition, although the dead zone can be reduced, it will not be eliminated
[0008] One of the main disadvantages of KR10-0843912 and EP1725821 is that the lower support that engages the grate is no longer easily accessible
Therefore, replacing the bars is a difficult and lengthy process
Improper grate maintenance can lead to increased grate wear, damage to process equipment and reduced productivity

Embodiment Construction

[0038] The general layout and function of mobile grate machines, such as those used in sintering or pelletizing plants, are well known, eg US6523673, and therefore will not be repeated here.

[0039] figure 1 A pallet truck 10 according to a first embodiment of the invention is shown. Such a pallet truck 10 comprises a body 12 with wheels 14 traveling on rails (not shown) of the moving grate machine. The top of the body 12 includes a perforated floor 16 for supporting bulk material to be handled. The perforated floor 16 is formed by a plurality of bars 18 between which spaces are provided to allow the passage of air in a downward or upward direction. The bars 18 are held in place by locking means 20 passing through end castings 22 of the body 12 and engaging the bars 18 from below.

[0040] A bellows (not shown) may, for example, be located below the pallet truck 10 for feeding hot air up or down through the pallet truck 10 . The hot gases pass through the spaces between t...

Abstract

The invention relates to a side wall (24) of a pallet car (10) for a travelling grate machine. According to the present invention, the side wall (24) comprises an upright portion (30), a wing portion(32) and a lower connection flange (34, 34'). The wing portion (32) has an upper surface acting as an extension of a loading surface of the pallet car (10), the upper surface (60) of the wing portion(32) being arranged at an angle with respect to the horizontal.

Description

technical field [0001] The present invention generally relates to pallet trucks for mobile grate machines for thermally treating loaded material such as iron ore or zinc ore. More specifically, the present invention relates to a sidewall and method for converting an existing pallet truck to a pallet truck with a greater capacity. Background technique [0002] Mobile grate machines are generally known in sintering or pelletizing plants, where bulk material is subjected to heat treatment. The mobile grate machine includes a plurality of pallet trucks from which the bulk material is received from the feeder. The pallet truck travels through at least one processing station on a horizontally extending top strand with air passing vertically over the pallet truck and through the bulk material. At the end of the upper strand, the heat-treated bulk material is dumped by gravity from a pallet truck, which then returns upside down to the front end of the moving grate machine. An exa...
