Description
Technical field
Technical field
The invention belongs to the pelletizing technology field, particularly a kind of pellet circular cooler discharge new technology is applicable to chain grate machine-rotary kiln pellet production line.
Background technology
In the pelletizing production process, particularly in chain grate machine-rotary kiln pelletizing production process, the discharge problem of central cooler is perplexing the insider always.In existing production technology, the discharge of central cooler generally all uses rubber conveyer to be used as conveying equipment, and there are a lot of problems in this technology:
1) be subjected to the central cooler structural limitations, because in the central cooler discharge process, the materials flow instability, instantaneous withdrawal rate is big, will deliberately strengthen specification when selecting rubber conveyer, causes the waste of equipment, and power consumption increases.However, at the material feeding point place of rubber conveyer, run the material situation and still exist, in case this situation occurs, can only lean on artificial treatment, post workman's workload heightens ecological deterioration.
2) in the rubber conveyer running vibration is arranged, because there is unstability in materials flow, in the few transportation section of material, pellet can produce under the vibration effect of adhesive tape beats, and just falls the rubber conveyer both sides after beating several times, causes spreading.All can occur on the sealing-tape machine of this phenomenon before advancing finished product ore deposit groove.This has had a strong impact on on-the-spot environment, has also caused the waste of material.
3) in the actual production, the pellet that central cooler is discharged may expect that temperature is very high, and the red heat material is discharged on the rubber conveyer can cause the adhesive tape localized burn, influences the adhesive tape bearing capacity.Must shut down the replacing adhesive tape when serious, thereby influence the continuity of producing, reduce the operating rate of main frame.
4) more seriously heat expects to be discharged on the rubber conveyer to cause fire, brings very big threat for post operation personnel's personal safety.
Along with the extensive popularization of chain grate machine-rotary kiln pellet production line, the discharge problem of central cooler is anxious to be solved, needs a kind of new central cooler process for layout, is satisfying under the situation of production requirement, avoids the appearance of above problem.Utility model patent number: ZL200520109774.4 provides a kind of novel heavy plate conveyer, can be used for the pellet circular cooler discharge of chain grate machine-rotary kiln pellet production line.
Summary of the invention

Major technique characteristics of the present invention:
1) the central cooler hopper is divided into adjustable gate, output regulating gate aperture according to pellet, the withdrawal rate of control central cooler, both avoided running the material phenomenon, guaranteed that again the follow-up equipment freight volume is stable, can select rational sealing-tape machine specification according to the output of pellet, avoid the excessive cost of equipment increase that brings of sealing-tape machine specification in the finished ball nodulizing transportation system, the problem that power consumption increases;
2) novel heavy plate conveyer is stable, between the chain bucket, is in relative static conditions between chain bucket and the material in the running, does not have the spreading phenomenon, has avoided the waste of material, has improved the environment of central cooler exhaust end;
3) can adopt different collocation forms, realize level transportation, upwards transportation, the collocation forms such as (comprising single angle, band break translation-angle etc.) of transportation downwards of pellet, can satisfy different technology arrangement needs;
4) the transmission device frequency control of novel heavy plate conveyer can guarantee that the pellet materials flow is stable according to the automatic freight volume of regulating novel heavy plate conveyer of the output of pellet, neither runs in the transportation and expects, continues to flow again.
5) novel heavy plate conveyer all is a metal structure, and critical components such as chain bucket adopt the steel alloy material, can be high temperature resistant, when the red heat material occurs, can not cause burning, and in transportation, also can play the effect of cooling again, avoided disaster hidden-trouble;
The invention has the advantages that: adopt this technology, can effectively control materials flow, do not run material, not spreading, avoid waste; Adopt this technology, can reduce subsequent transportation system equipment specification, save investment, reduce power consumption; The equipment that uses in this technology does not have inflammable link, effectively avoids the generation of fire, improves post workman's safety guarantee; Adopt this technology, stable equipment operation is reliable, long service life, and overhaul of the equipments is convenient, and maintenance time is short, expense is low, has improved the main frame operating rate, has reduced the material waste in the production process, clean environment.
