Description
Technical Field
The invention relates to the technical field of slag treatment equipment, in particular to a slag continuous drying device.
Background
The residue of ore after beneficiation or smelting is called slag, and the slag of blast furnace iron-making melt has no time to crystallize to form glassy substance when quenched. Is in a fine particle shape. The molten slag directly flows into a water tank to be cooled, and is called water quenching slag, commonly called water granulated slag. The slay is the active mixed material of cement through levigating back, and before levigating, the slay need carry out the drying, avoids the moisture influence grinding effect that carries on the slay, and among the present drying method, firstly through natural sunning, but this kind of mode is wide on one's side, receives weather influence degree great simultaneously, and drying effect is obvious when fine day, and rainy weather then can seriously influence drying effect. Secondly, drying is carried out through drying equipment, but in the existing drying equipment, slag needing to be dried is usually put into the equipment and then dried, and all the slag are uniformly taken out after drying is finished. Therefore, after the slag is dried by the drying equipment, the slag is still at a higher temperature, if workers are not aware of the fact that the slag is extremely easy to scald, and meanwhile, the slag cannot be continuously dried, so that the drying efficiency is low, and the production line type operation cannot be well carried out.
Disclosure of Invention
The present invention is intended to provide a slag continuous drying apparatus to improve the drying efficiency of slag.
In order to solve the technical problems, the invention provides the following technical scheme: the slag continuous drying device comprises a drying box and a drying mechanism, wherein a feeding hole is formed in the top of the drying box;

The working principle of the invention is as follows: during the use, start the heating wire earlier, because the spiral plate is made for the heat conduction material, therefore the heating wire can directly heat the spiral plate after starting, in order to improve its temperature, then continuously add the slay of treating the drying in the drying cabinet through the feed inlet, because the feed inlet size is fixed, consequently, the slay quantity that enters into in the drying cabinet in the unit interval is little different, after the slay enters into the drying cabinet, it can drop on the spiral plate, because the spiral plate receives the heating temperature of heating wire and uprises, consequently, after the slay fell on the spiral plate, can receive the direct heating of spiral plate, and then the slay temperature risees and makes the moisture of adhesion on the slay evaporate by being heated, follow spiral plate extremely up gliding in-and-down gliding in-process at the slay, the slay receives the continuous heating of spiral plate, simultaneously the slay constantly rolls in the slip in-process, the thermally equivalent, make the moisture on the slay evaporate fast, slide the slay from the spiral plate top to the in-process of bottom, accomplish the drying, then get in the slay through the feed port that communicates with the slay bottom, make the slay carry the temperature in the slay in the material box, the slay can further evaporation can collect the material that can be gathered by the evaporation of meeting the steam that the process of meeting of gathering.
The invention has the beneficial effects that: this scheme of adoption can continue to let in the slay in to the drying cabinet, and back in the slay gets into the drying cabinet, slides always to the bottom back from the top of spiral plate, can heat the completion drying work completely, then discharge from the bin outlet through connecing the workbin again, so continuously add the slay in to the drying cabinet, and the slay can be after the drying is accomplished and continuously discharge from the bin outlet for the drying efficiency of slay can improve, and this kind of mode specially adapted pipelined operation.
Further, the top that connects the workbin is equipped with a plurality of through-holes, fixedly connected with fan on the tank wall of drying cabinet, the air outlet of fan passes the tank wall of drying cabinet in proper order and the tank wall that connects the workbin to with the inside intercommunication that connects the workbin. Its purpose, during the use, start the fan, let in the air in the material receiving box during the fan operation, the air passes in the clearance of the slay after the drying in the material receiving box this moment, the mode through the heat transfer makes in the slay heat be taken away by the air, and after the air is heated and becomes hot-air, increase along with the air that the fan lets in the material receiving box, this hot-air is extruded and enters into the drying cabinet through the through-hole that connects the workbin top, utilize the heat of hot-air to heat the slay on the spiral shell board, make the heat of slay in the material receiving box obtain the reutilization.
Further, the spiral plate is made of a metal mesh plate made of copper, and gaps on the spiral plate are used for air to pass through. Its purpose through this kind set up the spiral plate both can heat the slay by the heating of electric heating wire, can let again from the hot-air of connect the workbin spun and pass, reinforcing drying effect.
Further, the pillar is the cavity setting, and the top of pillar is equipped with uncovered, uncovered box top that passes the drying cabinet and be located the surface on the box top of drying cabinet, uncovered department is equipped with the air discharge fan, and the air outlet of air discharge fan is outside the drying cabinet, the pillar is from top to bottom and the interval is equipped with a plurality of air vents, air vent and the inside intercommunication of pillar. During the use, start the fan, the fan exhausts outside the drying cabinet through uncovered during the operation, and the air reduction and then form the negative pressure in the pillar this moment, and the vapor that is heated the evaporation in the drying cabinet under the negative pressure effect this moment enters into the pillar through the air vent in, then through uncovered discharge under the effect of air discharge fan.
Further, the feed inlet department is equipped with the hopper, the hopper with drying cabinet fixed connection. Its purpose, through this kind of setting when adding the slay, directly add in the hopper, then let the slay automatically under the action of gravity can in dropping the drying cabinet through the feed inlet.
Furthermore, the bottom of the material receiving box is in a downward-inclined necking shape, and the discharge opening is formed in the lowest position of the material receiving box. The purpose is that slag in the edge receiving box is completely discharged through the arrangement.
