Abstract
The invention relates to a water-cooling slag cooling machine of a metal magnesium reduction slag waste heat utilization system and particularly relates to a slag cooling machine which supplies gas for production and living by utilizing reduction slag waste heat to produce steam. The slag cooling machine comprises an outer cylinder 1, an inner cylinder 2, a slag inlet device 3, a slag outlet device 4, a power transmission device 5, a bottom frame 6, a water inlet and outlet device 7 and an electrical control system 8, and is characterized in that the inner cylinder 2 is produced by graphite rods, and each cylinder adopts a water-cooling wall type structure. The slag cooling machine provided by the invention mainly has the advantages that the inner cylinder adopts the graphite rods, so that the heat conduction efficiency is high; heat exchange is performed with dispersed slag while water cooling, so that the slag cooling effect is good; and the water consumption is low, and the slag cooling machine has no special requirements on water quality.
Description
Technical field
The present invention relates to a kind of lag cooler making full use of the bootstrap system of magnesium metal reduction slag, especially relate to a kind of water-cooled lag cooler making full use of the bootstrap system of magnesium metal reduction slag.
Background technology
The manufacturing technique requirent of MAGNESIUM METAL is the high temperature of 1200 DEG C in temperature, and the reducing slag containing amount of heat produced in metal current magnesium production technique is arranged cooling by directly outer, not only causes heat energy not make full use of, and wastes a large amount of energy; Up to the present a kind of device that can fully replaced by the waste heat of reducing slag, utilize also is not had.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, provides a kind of device that can fully replaced by the waste heat of reducing slag, utilize.The present invention realizes by adopting following technical scheme formula: the water-cooled lag cooler that the present invention relates to a kind of magnesium metal reduction slag bootstrap system, particularly relate to a kind of lag cooler utilizing reducing slag waste heat for generating steam to supply productive life gas, lag cooler is made up of outer cylinder body 1, inner barrel 2, slag feeding device 3, deslagging device 4, power-driven gear 5, underframe 6, water inlet/outlet device 7 and electric control system 8, it is characterized in that described inner barrel 2 is made up of graphite rod, cylindrical shell adopts water cooled wall type structure.The outer cylinder body 1 of described lag cooler is metal construction unit, is welded with transmission mechanism 5 outside outer cylinder body.The inner barrel 2 of described lag cooler is welded with fixing spiral guide blade 2-1, is welded with slag extracting plate 2-2 between the fixing spiral guide blade in inner barrel.The slag feeding device 3 of described lag cooler is made up of slag feed pipe 3-1, end socket 3-2 and seal 3-3, and slag feed pipe 3-1 adopts compo pipe, and end socket 3-2 and seal 3-3 is that the casting of 45# steel manufactures.The water inlet/outlet device 7 of described lag cooler is arranged on same one end, is provided with swivel joint 7-1 at slag output end, connects water inlet 7-2 and rising pipe 7-3 by swivel joint.
advantage of the present invention is mainly reflected in:
1. inner barrel adopts graphite rod, and heat transfer efficiency is high; Loose slag charge carries out heat exchange with throwing simultaneously to adopt water-cooled, and cold slag is effective;
2. water loss is few, to water quality without particular requirement.
