Abstract
The utility model discloses a cleaned coal medium recovering device. The cleaned coal medium recovering device comprises a centrifugal machine, a magnetic separator and a magnetic tail drum, wherein a medium-removing pulverized coal pipeline is arranged at a material inlet of the centrifugal machine; a dewatering pulverized coal pipeline is arranged at a material outlet of the centrifugal machine; a sieve basket water spraying pipe is arranged below an outlet of the medium-removing pulverized coal pipeline and is provided with a sieve basket water spraying valve; the centrifugal machine is communicated with the magnetic separator through a centrifugate recovering pipeline; a medium pipeline is arranged below the magnetic separator; and the magnetic separator is connected with the magnetic tail drum through a tailings recovering pipeline. The cleaned coal medium recovering device is simple in structure; under the condition that the normal work of the centrifugal machine is not affected, cleaned coal with a medium before entering the centrifugal machine is subjected to water spraying for medium cleaning; centrifugate is thrown onto the magnetic separator through the centrifugate recovering pipe; after the centrifugate is subjected to medium recovering by the magnetic separator, the medium is discharged out of a medium pipeline, tailings enter the magnetic tail drum through the tailings recovering pipeline, the medium consumption can be lowered greatly, and the production cost can be saved; and the abrasion of pumps and spray nozzles in a coal washing system is relieved, so that the service life of equipment can be effectively prolonged.
Description
Technical field
The utility model belongs to coal preparation plant's wash coaling equipment technical field, particularly a kind of cleaned coal medium recovery device.
Background technology
At present, in the dense-medium separation production technology, the pan feeding of centrifuge is the screenings of cleaned coal vibration de-mediated dewatering screen, centrifuge pan feeding magnetic material content is subjected to the de-medium effectiveness of sieve bend, de-medium effectiveness, the cleaned coal amount of cleaned coal vibration de-mediated dewatering screen, the impact of the multiple factors such as pressure of spraying water, cause centrifugate to contain a large amount of coal washing media, these coal washing medium direct losses are in mine tailing, cause raw coal dielectric dissipation amount large, its consumption is at 1.1-1.5kg/t, waste a large amount of media, economic loss is large, and production cost is high.
The utility model content
The utility model provides a kind of simple in structure, cleaned coal medium recovery device that can effectively reduce dielectric dissipation.
For achieving the above object, the technical solution of the utility model is: a kind of cleaned coal medium recovery device, comprise centrifuge, magnetic separator and magnetic tail bucket, centrifuge feeding mouth place is provided with de-mediated smalls pipeline, discharging opening place and is provided with dehydration smalls pipeline, de-mediated smalls pipe outlet below is provided with the basket sparge pipe, and the basket sparge pipe is provided with the basket water injection valve; Centrifuge is connected with magnetic separator by the centrifugate recovery channel, is provided with medium pipeline below magnetic separator, and magnetic separator is connected by the mine tailing recovery channel with the magnetic tail bucket.
compared with prior art, the utility model has the advantages that: the utility model comprises centrifuge, magnetic separator and magnetic tail bucket, centrifuge feeding mouth place is provided with de-mediated smalls pipeline, discharging opening place and is provided with dehydration smalls pipeline, de-mediated smalls pipe outlet below is provided with the basket sparge pipe, and the basket sparge pipe is provided with the basket water injection valve, centrifuge is connected with magnetic separator by the centrifugate recovery channel, the magnetic separator below is provided with medium pipeline, magnetic separator is connected by the mine tailing recovery channel with the magnetic tail bucket, it is simple in structure, easy to implement, with low cost, in the situation that do not affect the centrifuge normal operation, by the basket sparge pipe, the band Jie cleaned coal that is about to enter centrifuge is sprayed water and wash Jie, centrifugate is got on magnetic separator through the centrifugate recovery channel, after through magnetic separator, centrifugate being carried out recovering medium, medium is discharged through medium pipeline, mine tailing enters in the magnetic tail bucket through the mine tailing recovery channel, can greatly reduce dielectric dissipation, raw coal is situated between to consume and can reduces 0.5kg/t, save production cost, the wearing and tearing of pump class and nozzle in alleviation coal washing system, effective service life of extension device.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
