Description
Technical Field
The utility model relates to a magnesite powder ore suspension calcines feeding device belongs to small carbonate granule thermal decomposition technical field and equips the trade.
Background
The suspension calcination technology has the advantages of high treatment efficiency, good powder activity, small space occupancy rate and the like. Firstly, the monomer suspension kiln can produce light-burned magnesia with the annual output of more than 10 ten thousand tons, and can produce light-burned magnesia with the average output of nearly 300 tons per day; secondly, the magnesite suspension calcination generally adopts flotation concentrate, tailings or magnesite powder, the calcination time is short, the flash calcination is carried out, the calcination time is uniform and stable, the undercurrent rate is low, and therefore the product quality is effectively guaranteed.
However, the main factor influencing suspension calcination is the stability and uniformity of the feeding system, generally, the form that the powder raw material is directly injected into the kiln through additional air is adopted, the fuel gas and the combustion air are mixed and combusted to form hot flue gas, the hot flue gas enters the kiln and forms heat exchange with the magnesite powder ore, and then the chemical decomposition reaction is realized to form magnesium oxide and carbon dioxide gas. The suspension kiln charging system is easy to have problems, mainly reflected in positive pressure operation in the kiln and easy to have air leakage phenomenon; the feeding speed of the fine ore is not easy to control; the control of the air quantity and the powder material proportion is difficult, etc.
Disclosure of Invention
In order to solve the prior art not enough, the utility model provides a feeding device is calcined in suspension of magnesite powder ore that easy operation, continuity are high.
The utility model provides a magnesite powder ore suspension calcines feeding device which characterized in that includes: the device comprises a storage bin, a vibrator, a spiral conveyor, a through hole, a blower, a gas pipeline and a combustion air pipeline;
the spiral conveyer material loading side is located under the feed bin, and feed bin lateral wall outside is equipped with the vibrator, and the spiral conveyer right-hand member passes the through-hole and gets into suspension kiln bottom feed inlet, and suspension kiln bottom feed inlet left and right sides respectively establishes gas pipeline and combustion air pipeline, and suspension kiln bottom feed inlet below is connected with the air-blower air outlet.
And the discharge hole of the screw conveyor is hermetically connected with the feed inlet at the bottom end of the suspension kiln.
The vibrator is any one of ZFB series, ZLD series or TNZS series.
Compared with the prior art, the beneficial effects of the utility model are that: 1) after sealing, the air leakage phenomenon is not easy to occur; 2) the adding amount of the fine ore can be quantitatively controlled through a screw conveyor, and the operation is simple; 3) the material is fed in succession, and the amount of wind can be controlled through the air-blower, has effectively controlled the relation between amount of wind and the reinforced volume.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the embodiments of the present invention and the accompanying drawings, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
See fig. 1, is the utility model relates to a magnesite powder ore suspension calcines feeding device embodiment structure sketch map, including feed bin 1, vibrator 2, screw conveyer 3, through-hole 4, air-blower 5, gas pipeline 6, combustion air pipeline 7.
The utility model provides a magnesite powder ore suspension calcines feeding device, includes: the device comprises a storage bin 1, a vibrator 2, a spiral conveyor 3, a through hole 4, an air blower 5, a gas pipeline 6 and a combustion air pipeline 7;
the feeding side of the screw conveyor 3 is located under the stock bin 1, a vibrator 2 is arranged on the outer portion of the side wall of the stock bin 1, the right end of the screw conveyor 3 penetrates through a through hole 4 to enter a bottom feed port of the suspension kiln, a gas pipeline 6 and a combustion air pipeline 7 are respectively arranged on the left side and the right side of the bottom feed port of the suspension kiln, and an air outlet of an air blower 5 is connected below the bottom feed port of the suspension kiln.
The discharge hole of the screw conveyor 3 is hermetically connected with the feed inlet at the bottom end of the suspension kiln.
The vibrator 2 is any one of ZFB series, ZLD series or TNZS series.
Magnesite powder is stored in a storage bin 1 and enters a spiral conveyor 3 through a vibrator 2, the spiral conveyor 3 pushes the magnesite powder to move forwards through a rotating blade, after the magnesite powder enters the right end of the spiral conveyor 3, the magnesite powder enters a cavity of a feed inlet at the bottom end of a suspension kiln through a through hole 4, an air blower 5 blows outside air into the cavity, and high-speed air drives the magnesite powder to enter the suspension kiln together. The gas fuel and the combustion air are mixed and combusted to enter the suspension kiln to exchange heat with the magnesite powder ore material, after the calcination and sintering are finished, the lighter light-burned magnesia enters the next stage of the suspension kiln to be collected, and the heavier magnesite powder ore under-burned ore is continuously calcined until the calcination process is finished.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
