Description
Technical field
The utility model is related to rotary kiln device field more particularly to a kind of ring formation of rotary kiln thing screening devices.
Background technology
Ring formation of rotary kiln is the furnace charge ring-type adhesion that height temperate zone inner wall occurs in rotary kiln.Slight adhesion
Referred to as kliner coating when influencing stove normal operating, that is, calls ring formation in case of adhering to.The main reason for adherency growth is in kiln
Oxidizing atmosphere, followed by kiln temperature is excessively high, reducing agent is insufficient in the bed of material or the Fu Shi bodies (FeO) of low reduction enter height temperate zone.
The mechanism adhered in kiln：The mixture for the miberal powder and coal ash that pelletizing is generated by friction with stress in kiln is in rotation process
By the oxidation of furnace gas, the miberal powder of partial reduction is set to be oxidized to floating scholar's body (FeO), and eutectic is formed with the SiO2 in coal ash
The ferrosilite of point, will soften at a temperature of 1050~1100 DEG C and be adhered on furnace wall.When the FeO of formation is few, adherency
Powder can be peeled off by dead weight；And when oxidizing atmosphere by force or when the temperature is excessively high, form more eutectic material, stickiness increases,
It is not easy to peel off, and then forms kliner coating, if adherency is constantly long thick, just at ring formation.
When coherent substance starts to peel off, the larger ring formation object of volume can be formed after falling off.And in ring formation object stripping process
In, ring formation object size, the labor intensity of operating personnel will be influenced by peeling off speed etc., serious also to cause showing for halt production cleaning
As then influencing production efficiency of equipment.

Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
As shown in Figure 1 to Figure 3, ring formation of rotary kiln thing screening device described in the utility model, including rotary kiln, main sieve
Body 1 and chute 2, the main sieve nest 1 are arranged below the discharge port 10 of rotary kiln, the oversize of the entrance of chute 2 and main sieve nest 1
Material outlet is corresponding and for receiving 1 on-the-sieve material of main sieve nest；It is provided with one section of opening portion on the bottom plate at 2 middle part of chute, in institute
It states and auxiliary sieve nest 3 is installed at opening portion, the surface of the auxiliary sieve nest 3 is concordant with 2 bottom plate of chute.
Wherein, the effect of main sieve nest 1 is for sieving the material being discharged from the discharge port 10 of rotary kiln, to allow
Corresponding material sieving, while preventing to be sieved with the large volume ring formation object that material is discharged out of rotary kiln, later again by phase
The ring formation object answered is transferred to from sieve in chute 2, to realize separation.And auxiliary sieve nest 3 is set, the purpose is to consider that ring formation object exists
When being transferred to from main sieve nest 1 in chute 2, a large amount of product may be carried, it is therefore desirable to carry the part in chute 2
Product further detached with ring formation object 2.Correspondingly, effect is efficiently separated in order to ensure auxiliary sieve nest 3, by auxiliary sieve nest 3
It is arranged at the middle part of chute 2, while requires the surface of auxiliary sieve nest 3 concordant with 2 bottom plate of chute to prevent the inhibition to material.
More specifically, under normal circumstances, product after screening will be sent to the respective handling equipment in downstream, such as by mistake
The product of sieve is sent into ring cold machine 4 and carries out subsequent processing.Therefore when being provided with the upstream devices such as corresponding ring cold machine 4；This practicality
Main collection funnel 5 is further provided in novel below main sieve nest 1, the main collection funnel 5 is used to collect the mistake of main sieve nest 1
Sieve material is simultaneously delivered to the upstream devices such as ring cold machine 4；Meanwhile the lower section of auxiliary sieve nest 3 being also provided with auxiliary collection funnel accordingly
6, the auxiliary collection funnel 6 is used to collect the sieving material of auxiliary sieve nest 3 and is delivered to the upstream devices such as ring cold machine 4.
In addition, in order to improve the automatic landing effect of the oversize on main sieve nest 1 (i.e. the ring formation object of large volume), to avoid
Need operating personnel that oversize is transferred in chute 2 manually；The main sieve nest 1 is obliquely installed in the utility model, and
The entrance of chute 2 is located at the lower section of the bottom edge side of main sieve nest 1；In this way, from the material that the discharge port 10 of rotary kiln is discharged, in master
It will be moved down by its own gravity on sieve nest 1, that is, facilitate material to be sieved, while again can be by oversize along inclined main sieve nest
1 moves down, and then is directly transferred in chute 2, is then slided further along the chute 2 being obliquely installed.More specifically, above-mentioned
Main sieve nest 1 described in utility model, tilt angle theta may be configured as 15 °~80 °, be such as set as 30 ° of angle of inclination；When
So, specific tilt angle theta can be depending on actual conditions.

Screening, to prevent ring formation object from entering upstream device；Specifically, with reference to shown in attached drawing 3, main sieve nest described in the utility model
1 includes grating 7 and reinforcing rib 8；The grating 7 has a plurality of.When main sieve nest 1 is obliquely installed, by inclining for grating 7 and main sieve nest 1
Tilted direction is consistent, i.e., forms the shape body that main sieve nest 1 is integrally inclined to set by being obliquely installed grating 7；Correspondingly, adjacent
The sieve pore 9 of bar shaped is formed between two gratings 7；It is sieved in this way, product will be realized by sieve pore 9, and the ring formation object of large volume is by nothing
Method can not be sieved by sieve pore 9.Specifically, the wherein size of sieve pore 9, in combination with the actual conditions size of product
Situation is rationally arranged.And the effect that reinforcing rib 8 is arranged is to enhance the structural strength of entire main sieve nest 1, such as preferably setting
The reinforcing rib 8 is vertical with the direction of grating 7, and each grating 7 is connected by reinforcing rib 8, i.e., is carried out with reference to shown in attached drawing 3
Setting.
Without loss of generality, structure identical with main sieve nest 1 can be used in the auxiliary sieve nest 3 in the utility model completely；I.e.
Auxiliary sieve nest 3 is also by the structure compositions such as corresponding grating 7 and reinforcing rib 8；Correspondingly, its grating 7, the spacing of reinforcing rib 8, size are big
The size etc. of small equal and corresponding sieve pore 9 can be not intended to limit main sieve nest 1 and auxiliary depending on actual conditions, in the utility model
The corresponding size needs of sieve nest 3 are completely the same, and the two can be rationally arranged respectively according to actual conditions.
