Novel grate type cooler

Abstract

The invention discloses a novel grate type cooler, comprising a grate bed and an air room; the grate bed is arranged above the air room; the grate bed comprises fixed grate boards and movable grate boards; and the fixed grate boards and the movable grate boards are alternately arranged with one another. The novel grate type cooler is characterized by further comprising a movable frame and a support guider, wherein the movable frame is driven by a drive device to move in a reciprocating way and is arranged in the air room; the support guider is used for supporting the movable frame and is arranged outside the air room; and the movable frame is connected with the support guider by a connecting beam. The support guider is arranged outside the air room, and lubricating oil can be applied to the support guider without opening the air room, so that the friction coefficient of the novel grate type cooler is reduced, the attrition of the support guider is avoided, and the settlement of the movable grate boards caused by the attrition of a support device is overcome. The settlement of the movable grate boards is overcome, so that overlapped gaps between the movable grate boards and the fixed grate boards can be reduced at 2+ / -0.5mm; and therefore, the novel grate type cooler is higher than the existing national industry standard.

Description

technical field [0001] The invention relates to a novel grate cooler. Background technique [0002] like figure 1 , figure 2 and image 3 As shown, the grate cooler includes a grate bed 10 and an air chamber 20, and the grate bed 10 is arranged above the air chamber 20. The grate bed 10 is covered with a heat-resistant steel grate plate, and the grate plate is divided into a movable grate plate 11 and a fixed grate plate 14. Movable grate plates 11 and fixed grate plates 14 are alternately arranged. There is a gap between the movable grate plate 11 and the fixed grate plate 14, and the size of the gap is within 3 ± 1 mm. Fixed grate plate 14 is installed on the fixed beam 15, and fixed beam 15 is to be fixed on the frame 50 of body. Fixed beam 15, fixed grate plate 14 are all stationary. Movable grate plate 11 is installed on the movable beam 12. The movable beam 12 is installed on the movable frame 13 . The movable frame 13 is supported by three pairs of supportin...

AI Technical Summary

Problems solved by technology

The gap will become larger, resulting in increased material leakage, which will affect the normal operation of the cooler

This kind of problem that affects the normal operation of the cooler due to the wear of the support roller 41 and the wheel rail 42 accounts for 80% of the damage to the grate cooler

The dust in the air chamber 20 is large, and lubricating oil cannot be used, which is not conducive to adopting measures to reduce wear

The gap between the movable grate plate 11 and the fixed grate plate 14 is set to 3±1mm, also because of the unavoidable wear problem

If the gap is too small, the movable grate plate 11 and the fixed grate plate 14 may be stuck after slight wear and tear, and the machine is forced to stop

The gap is set to 3±1mm, which leads to increased material leakage
