Flexible sealing and water sealing rotary forced-air cooler

Abstract

This invention discloses a flexible sealing and water sealing rotary forced-air cooler, adopting multiple air blowers to connect with an air box through an air pipe, wherein the outer circumference of the top of the air box is connected with a side of a flexible sealing device, the other side of the flexible sealing device is connected with a rotary beam of a trolley, a water sealing device is respectively installed at the outsides of the flexible sealing device and the rotary beam, the outer circumference of the trolley is movably connected with a rotary sealing device, the water sealing device comprises an annular water tank the top of which is connected with a cover board, the centre of the annular water tank is provided with an annular clapboard, the annular clapboard is fixed at the bottom of the trolley, and the annular water tank is fixed on a flat slab of the stand. The connection scheme of the flexible sealing device and the flat slab of the stand overcomes the disadvantages of the gap existence, gas leakage, low working efficiency of annular cooler and electricity waste of the movable-static flexible sealing which uses a rubber sealing plate as a main body, and the invention is suitable for cooling different kinds of ores rotating on trolley.

Description

technical field [0001] The invention relates to a blast ring cooler with flexible seal and water seal for metallurgical sintering cooling. Background technique [0002] The seal of the existing annular cooler is a dynamic and static flexible seal composed of rubber sealing plates to complete the sealing function. Due to the large size of the annular cooler, the diameter ranges from 20 meters to 50 meters, and the weight ranges from hundreds of tons to thousands. t, the installation base of the flexible rubber sealing plate that forms the sealing structure and the flat or conical rigid sealing surface in contact with it is a riveted structural part, which is difficult to process, and it is difficult to achieve complete sealing on the joint surface manufactured. As a result, although the flexibility is compensated after installation, there are still gaps on the sealing surface of the combination of dynamic and static, resulting in air leakage, resulting in a decrease in the wo...

[0002] The seal of the existing annular cooler is a dynamic and static flexible seal composed of rubber sealing plates to complete the sealing function. Due to the large size of the annular cooler, the diameter ranges from 20 meters to 50 meters, and the weight ranges from hundreds of tons to thousands. t, the installation base of the flexible rubber sealing plate that forms the sealing structure and the flat or conical rigid sealing surface in contact with it is a riveted structural part, which is difficult to process, and it is difficult to achieve complete sealing on the joint surface manufactured. As a result, although the flexibility is compensated after installation, there are still gaps on the sealing surface of the combination of dynamic and static, resulting in air leakage, resulting in a decrease in the working efficiency of the ring cooler, and at the same time increasing the working load of the ring cooler, resulting in waste of kinetic energy and air leakage. The resulting dust is blown to the outside of the ring cooler, causing air pollution and environmental pollution

Aiming at the air leakage problem of the annular cooler, a patent with the publication number CN101118118A has been published. The structure of this patent changes greatly, the weight increases greatly, and the cost increases; the static sealing rubber plate contacts the red-hot ore, and the rubber plate is easy to burn and easy to burn. Aging will cause the rubber plate to be damaged quickly, resulting in short service life and easy air leakage; the air supply direction is side air supply, more connecting pipes, and more faults; it is not suitable for the transformation of existing equipment
