Description
Technical Field
The utility model belongs to the technical field of sintering production, and particularly relates to a quicklime sorting device for sintering production.
Background
The quicklime powder is one of the essential raw materials for sintering production, has huge effect in the sintering process, not only provides CaO for sintered ores, but also can improve the uniform mixing and pelletizing process of the mixture and also has the effect of increasing the temperature of the mixture. During sintering production, the quicklime powder generally enters a quicklime bin of the batching chamber through a lime beating pipe in a pneumatic conveying mode, is output through a feed opening at the bottom of the bin, and then participates in sintering production. The particle size of the quicklime powder is required to be small (generally, the proportion of less than 3mm is required to be more than 90% or 95%), so that the quicklime powder can more easily participate in the sintering reaction in the sintering process, and the reaction is more complete and sufficient. However, in the actual production process, the proportion of large particle size (usually greater than 3mm) in the quicklime powder is high, when the particle size of the quicklime powder is large, incomplete or insufficient reaction easily occurs in the sintering process, so that the quicklime powder remains in the finished sintered ore, the sintered ore has a 'white spot' phenomenon, and the white spots can react with moisture in the air in the sintered ore transportation process, so that the sintered ore is pulverized, and the quality of the sintered ore is reduced.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems in the prior art, the utility model provides the quicklime sorting device for sintering production, which can reduce the proportion of large-particle-size quicklime powder in sintering production, improve the white point phenomenon of sintering ores and reduce the pulverization rate of the sintering ores.
The utility model is realized in this way, a sintering production uses the calcined lime sorting unit, the apparatus is installed between calcined lime feed bin and ash striking pipe, characterized by, mainly include feed pipe and blanking elephant trunk, one end of feed pipe communicates with ash striking pipe, another end connects the vertical downcomer; the blanking chute obliquely extends downwards to the upper part of the operating platform; the vertical downcomer is communicated with the feeding pipe and the discharging chute, and a vertical filter plate is arranged at the communication position of the upper end of the downcomer and the feeding pipe; an inclined plane filter plate is obliquely and downwards arranged at the lower end of the vertical filter plate; the lower end of the vertical downcomer is connected with a quicklime bin; the lower end of the blanking chute is connected with the storage bin.
Preferably, the storage bin is provided with a viewing port.
Preferably, the bottom of the storage bin is provided with a universal caster.
The utility model has the advantages and technical effects that: by adopting the technical scheme, the proportion of the large-particle-size quicklime powder in sintering production is reduced, the white spot phenomenon of the sinter is improved, and the pulverization rate of the sinter is reduced. Meanwhile, the online automatic separation can be realized, special equipment for separation and power transmission is not required to be configured, the large particle size automatically slips downwards by means of self weight, and the cost is reduced; in addition, the utility model also has the advantages of simple structure, convenient manufacture and the like.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
Referring to fig. 1, a quicklime sorting device for sintering production is installed between a quicklime bin 1 and a lime beating pipe 2, and mainly comprises a feeding pipe 3 and a discharging chute 4, wherein one end of the feeding pipe is communicated with the lime beating pipe, the other end of the feeding pipe is connected with a vertical downcomer 5, and in order to ensure the stability of the vertical downcomer, a support mechanism 7 is fixedly installed on an operation platform 6 and used for supporting and fixing; the blanking chute obliquely extends downwards to the upper part of the operating platform; the vertical downcomer is communicated with the feeding pipe and the blanking chute, and a vertical filter plate 8 is arranged at the communication position of the upper end of the downcomer and the feeding pipe; the lower end of the vertical filter plate is obliquely downwards provided with an inclined filter plate 9; the two are the same and equidistant; the lower end of the vertical downcomer is connected with a quicklime bin 1; the lower end of the blanking chute is connected with a storage bin 10.
Preferably, the storage bin is provided with an observation port 10-1, so that the condition that lime with large particle size is collected in the storage bin can be observed conveniently.
Preferably, the bottom of the storage bin is provided with universal casters 10-2, so that the storage bin is convenient to carry integrally and discharge large-particle-level quicklime.
The working principle of the utility model is as follows: quicklime powder is added into a feeding pipe through a lime adding pipe, the quicklime powder enters a sorting device through the feeding pipe, small-particle-grade quicklime powder enters a descending pipe through a vertical filter plate and an inclined-plane filter plate and then enters a quicklime bin through the descending pipe, large-particle-grade quicklime powder is filtered by grate bars on the vertical filter plate and the inclined-plane filter plate, enters a blanking chute through the side surfaces of the vertical filter plate and the inclined-plane filter plate under the action of gravity and then enters a storage bin through the blanking chute for centralized collection; regularly look over the condition in the storage silo through the viewing aperture on the storage silo, when the large size level quicklime powder is more in the storage silo, in time clear out the large size level quicklime powder in the storage silo.
