Abstract
The present invention relates to a process and a device for mixing active lime powder and liquid adhesive. Liquid adhesive which accounts for 2 to 3% of the amount of active lime is heated to 90 to 120 DEG C, and the liquid adhesive is pressurized to P which is more than or equal to 0.5MPa; then, the liquid adhesive is atomized into liquid drops in the size of 5 to 1000 microns via a spray nozzle, and the liquid drops are sprayed on the active lime powder which is spread in a mixing chamber. The mixing chamber is composed of a material feeding chamber, a material spraying chamber and a mixing chamber, wherein the liquid spray nozzle is arranged on the wall of the mixing chamber. Active lime balls or active lime blocks produced by the present invention have the advantages that strength and impact resistance are enhanced, a breaking rate is low, and the activity of active lime is not reduced. The present invention having the advantages of simple structure, convenient operation, low breaking rate and no reduction of the activity of active lime completely conforms to requirements for steel smelting.
Description
The invention belongs to the active lime powder forming technique of steel-making with additive, specifically is a kind of active lime powder and liquid-containing binder hybrid technique and equipment.
Producing steel-making a part of Powdered quickened lime clout of meeting generation in the quickened lime process, these Powdered quickened lime clouts need just can be used for steel-making through adding the type of being pressed into.Because the intensity of lime is different after the different compression mouldings of ball press pressure.Its shock resistance does not all reach the process for making requirement, need add certain binding agent for satisfying this requirement, can not use big gauging as binding agent from economy and process for making angle, general add-on is below 4% for quickened lime only, again owing to this oil viscosity as binding agent is bigger, in quickened lime, do not have seepage force substantially, utilize existing technology and equipment to be difficult to it is evenly joined in the active lime powder, do not reach the adherent purpose.The present invention is exactly at the problems referred to above, invents a kind of active lime powder and liquid-containing binder hybrid technique and equipment, to satisfy active lime powder and liquid-containing binder blended needs.
The object of the present invention is achieved like this, a kind of active lime powder and liquid-containing binder hybrid technique, be that 2～3% liquid-containing binders with the quickened lime amount are heated to 90～120 ℃, be forced into P 〉=0.5MPa, make its drop that is atomized into 5～1000 microns through shower nozzle, be sprayed onto on the active lime powder of trickling down in mixing section.
For realizing purpose of the present invention, the invention provides the equipment of a kind of suitable active lime powder and liquid-containing binder hybrid technique, it is made up of feed chamber, material-strewing device, mixing section, its characteristics are that material-strewing device is connected on the bottom that feed chamber lower end mixing section is positioned at material-strewing device, and fluid jetting head is contained in and mixes on the locular wall.
The equipment concrete structure of this active lime powder and liquid-containing binder hybrid technique is to be provided with rotary scattering plate in the material-strewing device, the motor drive belt, and belt pulley drives scattering plate, and switch-plate is housed on the scattering plate.
This active lime powder also has fluid jetting head to be contained in pairs with the equipment concrete structure of liquid-containing binder hybrid technique to mix on the locular wall, and its logarithm is N (N 〉=1).On fluid jetting head, be provided with setting device.
For realizing purpose of the present invention, it is 200～350 rev/mins that its concrete measure also has the revolution of the scattering plate in the material-strewing device.
Advantage of the present invention and effect have: 1, it has at first solved the problem that active lime powder utilizes again, use the small amount of liquid binding agent under certain technical parameter condition, to utilize shower nozzle that liquid mist is changed into drop, itself and active lime powder are mixed, intensity and shock resistance after the moulding of increase active lime powder.
2, it provides a kind of small amount of liquid binding agent and powdered object blended equipment, shower nozzle is positioned on and mixes on the locular wall, be sprayed onto rotating disk by material-strewing device after the liquid adhesive atomizing and be spread across on the active lime powder in the mixing section, it is mixed, it is simple in structure, easy to operate, batch mixing speed is fast, and the amount of active lime powder amount and liquid-containing binder all can reconcile, and breakage rate is low after the shaper extrusion forming, and do not reduce the activity degree of quickened lime, meet the requirement of steel-making fully.
Description of drawings:
Accompanying drawing is the structural representation of present device.
Below in conjunction with accompanying drawing a specific embodiment of the present invention is done with explanation:
A kind of active lime powder and liquid-containing binder hybrid technique, be 2～3% liquid-containing binders with the quickened lime amount, the present invention is to be binding agent with heavy oil, make it be heated to 90～120 ℃, be forced into P 〉=0.5MPa, make its drop that is atomized into 5～1000 microns through fluid jetting head 5, be sprayed onto on the active lime powder of trickling down in mixing section 6.
Purpose of the present invention also realizes by the equipment of a kind of suitable active lime powder and liquid-containing binder hybrid technique, this equipment is made up of feed chamber 1, material-strewing device 2, mixing section 6, its characteristics are that material-strewing device 2 is connected on feed chamber 1 lower end, mixing section 6 is positioned at the bottom of material-strewing device 2, and fluid jetting head 5 is contained in and mixes on the locular wall 6.
The equipment concrete structure of this active lime powder and liquid-containing binder hybrid technique is to be provided with rotary scattering plate 4 in the material-strewing device 2, electric motor 7 drive pulleys 8, belt pulley 8 drives scattering plate 4, switch-plate 9 is housed on the scattering plate 4, active lime powder enters feed chamber 1 from feeding mouth 3, fall into again on the scattering plate 4 of material-strewing device 2, pushed equably in the batch mixing chamber 6 by switch-plate 9.
The equipment concrete structure of this active lime powder and liquid-containing binder hybrid technique also has fluid jetting head 5 to be contained in pairs on mixing section 6 walls, and its logarithm is N (N 〉=1), its objective is oil droplet evenly is sprayed onto on the active lime powder.
