Dry-type completely automatic control cold slag machine

Abstract

The invention provides a dry-type completely automatic control cold slag machine, comprising a frame, a multi-layer ring trough, a motor transmission mechanism, a vertical shaft, multi-groups of turnplate scraper mechanisms, a water inlet main pipe, a water outlet main pipe, a slag inlet, a slag outlet, an air-exhaust and heat-dissipation mechanism and an automatic control mechanism, wherein the automatic control mechanism comprises a central controller, and a water temperature transmitter, a water inlet control mechanism and a slag inlet control mechanism which are connected with the central controller by telecommunication. The dry-type completely automatic control cold slag machine can realize completely automatic control according to the change of the temperature, has the advantages of quick cooling speed, no leakage, long service life, and the like, and can improve the cold slag quantity by one third and prolong the service life by two times compared to the prior art.

Description

technical field [0001] The invention relates to a boiler slag cooling device, in particular to a dry-type automatic control slag cooling machine. Background technique [0002] Boiler slag can be used as raw material for making cement after dry cooling. This dry cooling is generally carried out by a slag cooler. The slag cooler is installed at the slag outlet of the boiler. It can cool the high-temperature cinder of more than 1,000 degrees through double cooling of sealed circulating water and air cooling, and quickly reduce the temperature to less than 100 degrees. [0003] The slag cooler operates at high temperature and is subject to high temperature erosion and friction for a long time, so it is easily oxidized and deformed. Due to the different materials and structures used in the prior art slag cooling machine, and the protection device is not matched, so the performance is very different, mainly in: 1. The cooling protection of the upper bearing is not in place, so t...

[0003] The slag cooler operates at high temperature and is subject to high temperature erosion and friction for a long time, so it is easy to oxidize and deform

Due to the different materials and structures used in the prior art slag cooling machine, and the protection device is not matched, so the performance is very different, mainly in: 1. The cooling protection of the upper bearing is not in place, so that the upper bearing is quickly damaged, resulting in cooling 2. Due to the insufficient strength of the materials and ribs used on the upper plane, it deforms quickly under high temperature operation, which greatly reduces the slag discharge rate, and even fails to work; 3. The welding process is defective, and water leakage is very easy to occur , resulting in a decline in activated carbon from cinders, reducing the value of reuse; 4. Since there is no terminal control system, workers operate in harsh environments, and the labor intensity is very high
