A high-temperature resistant motion sealing device for a two-stage cement clinker grate cooler

Abstract

The invention relates to a two-section type high-temperature motion sealing device for a cement clinker grate cooler. The two-section type high-temperature motion sealing device for the cement clinkergrate cooler comprises an upper-section grate bed, spring gaskets, connecting shafts, an auxiliary connecting plate, a first wear-resisting sealing plate, second connecting bolts, engaging teeth, a grate cooler baffle top installation plate, a second wear-resisting sealing plate, an air chamber blocking wall and a lower-section grate bed. The upper-section grate bed is connected with a connectingframe through first connecting bolts, and the lower-section grate bed is arranged on one side of the air chamber blocking wall. By means of the two-section type high-temperature motion sealing devicefor the cement clinker grate cooler, the engaging teeth are arranged on the surface of the first wear-resisting sealing plate at equal intervals, the shape of the engaging teeth is in a semispherical, and the second wear-resisting sealing plate and the first wear-resisting sealing plate are of the same structure. By means of the arrangement, the device can be better connected with the air chamberblocking wall in a sealed manner, meanwhile, the device can be connected with the air chamber blocking wall more tightly due to design of the engaging teeth, the sealing performance between the device and the air chamber blocking wall is improved, and heat losses are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of cement production and processing, in particular to a high-temperature-resistant motion sealing device for a two-stage cement clinker grate cooler. Background technique [0002] The cement clinker grate cooler is a large-scale equipment that transports a large amount of 1400°C cement clinker through the moving grate bed and cools it to 100°C with the cold air provided by the air chamber at the bottom of the moving grate bed. A certain number of parallel grate beds are determined according to the production capacity, and each row of grate beds is driven forward or backward by the drive cylinder through the control system. In order to improve thermal efficiency, the new technology is to divide the 30-meter-long grate bed into upper and lower sections, so that the cement clinker falls through the upper section of the grate bed to the lower section of the grate bed to accelerate cooling. However, due to the 5...
