Description

Technical Field

[0001] The utility model relates to the field of grate coolers, in particular to a flexible supporting device and a grate cooler. Background Art

[0002] Grate cooler is the main equipment in the clinker burning system, and its main function is to cool, recover heat and transport clinker. Grate bed is a main component of grate cooler, and its reciprocating movement is driven by hydraulic system.

[0003] In the actual production process, when the kiln system increases production, the grate bed material layer will thicken as the raw material feed increases. Correspondingly, it is necessary to increase the pressure of the hydraulic system to adjust the grate speed of the grate cooler, that is, the moving speed of the grate bed. However, long-term high-load operation of the hydraulic system is likely to cause oil leakage in the hydraulic station, which will lead to equipment failure and production reduction. Then the hydraulic system needs to reduce the pressure accordingly, and equipment failure will be relatively reduced, which forms a vicious circle as follows: increased production-thickening of the material layer-increased pressure of the hydraulic system-equipment failure-reduction in production-reduction in pressure-reduction in equipment failure, which causes great trouble to the continuous operation of the kiln system.

Correspondingly, it is necessary to increase the pressure of the hydraulic system to adjust the grate speed of the grate cooler, that is, the moving speed of the grate bed. However, long-term high-load operation of the hydraulic system is likely to cause oil leakage in the hydraulic station, which will lead to equipment failure and production reduction. Then the hydraulic system needs to reduce the pressure accordingly, and equipment failure will be relatively reduced, which forms a vicious circle as follows: increased production-thickening of the material layer-increased pressure of the hydraulic system-equipment failure-reduction in production-reduction in pressure-reduction in equipment failure, which causes great trouble to the continuous operation of the kiln system.
