Abstract
The utility model relates to a continuous coal blending system for tar residue, belonging to coking equipment; the continuous coal blending system for tar residue is characterized by comprising a tar residue hopper, a conveyer belt, a transfer station and a crusher, wherein the conveyer belt is arranged just under a tar residue outlet of the tar residue hopper; a conveying destination end of the conveyer belt is provided with the transfer station; the crusher is arranged at an outlet end of the transfer station; and a discharge hole of the crusher is connected with a coal storage tower. The continuous coal blending system for tar residue is capable of realizing mechanical tar residue treatment; when the tar residue is mixed into coking coal for burning, the mixing effect is good, the caking ability of the coking coal can be improved, and the coking quality is improved; and the coking coal mixed with the tar residue can be used for replacing high-quality coal, so that the cost is reduced.
Description
Technical field
The utility model relates to a kind of coking production equipment, and is particularly a kind of with the waste material in the coking production---and coke tar refuse is sneaked into the system that coking coal is used for coking.
Background technology
In coking production, coal gas also can be taken coal grain lighter in the stove coal, burnt grain out of from the coke furnace carbonization chamber overflow process in the lump, is separated in mechanical slag hanging groove, is called coke tar refuse.
The coke tar refuse complicated component wherein is no lack of objectionable impurities, and poor fluidity, is difficult to process.So general coking coal enterprise is transferred to other unit with it to process.Also there are some enterprises to adopt and directly sneak into the Simple treatment method that burns in the coking coal, but foregoing, the flowability of coke tar refuse extreme difference causes mixing inhomogeneous, affects coke quality, and contain ammoniacal liquor in the coke tar refuse, deal with improperly or incorrect burning also can cause environmental pollution.
So at present, be the hang-up of coal chemical enterprise to the processing of coke tar refuse always, more there is not perfect mechanised system can satisfy processing requirements.
The utility model content
The utility model is exactly the thinking for the described burning coke tar refuse of background technology, designed the continuous Coal Blending System of a kind of brand-new coke tar refuse, realization coking coal slag mixes allocates automatization and the mechanize that is used for coking in the coking coal into, to overcome the described existing simply dealt defective of background technology.
Native system is comprised of tar slag bucket, travelling belt, transfer point, pulverizer, travelling belt is installed under the coke tar refuse outlet of tar slag bucket, the conveying destination of travelling belt is provided with transfer point, and pulverizer is arranged on the exit end of transfer point, the discharge port access storage coal tower of pulverizer.
For the defective that solves the coke tar refuse poor fluidity, is difficult to fall, preferably: be provided with extrusion screw in the tar slag bucket.
This cover system of the present utility model can be full-automatic, mechanize with full and uniform being mixed in the coking coal in the storage coal tower of coke tar refuse, working process is reliable continuously, almost cost free dispose coke tar refuse, do not have secondary pollution.And fully be blended in the coking coal, the advantage that can not only utilize coke tar refuse to have good burning performance, tar ingredients wherein can also improve the agglutinating value(of coal) of coal, improves coke quality; The later breeze that burns can also improve the intensity of coke.So the utility model can play the beneficial effect that reduces cost, improves end product quality.
Description of drawings
Fig. 1 is structure iron of the present utility model.
Embodiment
Contrast Fig. 1 illustrates concrete structure of the present utility model and mode of operation.
Common coking coal blending system mainly is that travelling belt and storage coal tower consist of, and this cover Coal Blending System of the present utility model also takes into full account processing, the mixing of coke tar refuse.
The utility model mainly is comprised of tar slag bucket 1, travelling belt 2, transfer point 3, pulverizer 4 and storage coal tower 5.Tar slag bucket 1 is the device of depositing the coke tar refuse that mechanical dreg scraping trough separates, has upper shed and coke tar refuse outlet 11, because the coke tar refuse flowability is too poor, possibly can't free-falling, block outlet, impact is produced continuously, so be provided with extrusion screw 12 in the tar slag bucket 1, guarantees that by extrusion screw 12 continuous uniform of coke tar refuse falls.Travelling belt 2 is the transportation coking coal continuously, and the coke tar refuse that is arranged in tar slag bucket 1 exports 11 belows, and the destination of coal travelling belt is provided with transfer point 3, and the exit end of transfer point 3 is equipped with a pulverizer 4, the discharge port access storage coal tower 5 of pulverizer 4.
In the time of native system work, after the coke tar refuse that produces is continuously separated by dreg scraping trough, introduce tar slag bucket 1, under the effect of the extrusion screw 12 that rotates, fall from tar cinder notch 11, successively freely falling body is fallen on the conveying belt (2), the upper coking coal that continuous conveying is just arranged originally of conveying belt (2), conveying belt (2) just together is transported to transfer point 3 with coking coal and coke tar refuse like this, enters pulverizer (4) through transfer point 3, pulverizer fully is pulverized and mixed coking coal and coke tar refuse, become mixture, directly deposit storage coal tower (5) in, if do not store the coal tower, also can pile dump, prepare at any time the stove burning.
Through practice, be about into 6 ‰ ~ 8 ‰ of stove dry coal amount according to the isolated coke tar refuse of tar ammonia separating technology, quantity is little, has good burning performance, and allocating in the coking coal can the Substitute For Partial fat coal, reduces the coal blending amount, reduces cost.Simultaneously, the tar of half is arranged approximately in the coke tar refuse, can improve the degree of cohering of coking coal, it is more stable to burn.After the burning, the breeze in the coke tar refuse can improve again the intensity of coke.
Claims (2)
1. continuous Coal Blending System of coke tar refuse, it is characterized in that: formed by tar slag bucket (1), travelling belt (2), transfer point (3), pulverizer (4), travelling belt (2) is installed under the coke tar refuse outlet (11) of tar slag bucket (1), the conveying destination of travelling belt is provided with transfer point (3), pulverizer (4) is arranged on the exit end of transfer point, the discharge port access storage coal tower (5) of pulverizer.
2. the continuous Coal Blending System of coke tar refuse according to claim 1 is characterized in that: be provided with extrusion screw (12) in the tar slag bucket (1).
