[0027] See Figures 1-3 As shown, the dust collection and separation device for the dolomite crushing process described in this embodiment includes a dust collection hood 1, a cyclone separator 2, a buffer bin 3, and an air classifier 4. The dust collection hood 1 is used to cover the dolomite crushing equipment and is connected to the cyclone separator 2 through an exhaust system 5. A dust hopper 21 is provided at the bottom end of the cyclone separator 2, and the dust hopper 21 is connected to the buffer bin 3. The air classifier 4 is connected to the buffer bin 3 to screen the dolomite dust according to different particle sizes for classified utilization.

[0028] This embodiment has a simple structure and a reasonable design. By setting the dust collection hood 1 and connecting it to the exhaust system 5, the dolomite dust is collected into the cyclone separator 2, and then through dust collection treatment and separation treatment, the screening of dust with different particle sizes is realized, so as to carry out classified utilization.

[0029] In some embodiments, the cyclone separator 2 has a conical cyclone cylinder 22, and an air inlet 23 and an air outlet 24 are provided at the top end of the cyclone cylinder 22. The dust hopper 21 is located at the bottom end of the cyclone cylinder 22, and a discharge control valve is provided at the bottom end of the dust hopper 21.

[0030] In this embodiment, the setting of the cyclone separator 2 is specifically shown. By setting a discharge control valve at the bottom end of the dust hopper 21, it is convenient to flexibly control the discharge and avoid blockage caused by untimely dust treatment at the rear end.

[0031] Specifically, the exhaust system 5 has an induced draft fan 51 and exhaust pipe components 52. The induced draft fan 51 is installed on the exhaust pipe components 52, and the two ends of the exhaust pipe components 52 are respectively connected to the dust collection hood 1 and the air inlet 23.

[0032] In this embodiment, by setting the induced draft fan 51 and the exhaust pipe components 52, it is convenient to suck the dust generated during the dolomite crushing process into the cyclone separator 2 through exhaust, so as to effectively control the diffusion of dust and improve the collection efficiency.

[0033] In some embodiments, the buffer bin 3 is provided with a weighing level meter.

[0034] In this embodiment, by setting a weighing level meter, the level information can be effectively controlled, avoiding the problems of too little or too much dust in the buffer bin 3, and effectively ensuring the stable operation of the subsequent processing. When there is less material in the buffer bin 3, the bottom discharge control valve of the ash hopper 21 is opened to supplement the dust.

[0035] In some embodiments, the air classifier 4 includes an air classifier 4 body, a classification wheel 42, a driving device 43, a raw material inlet 44, a secondary air inlet 45, a fine powder outlet 46, and a coarse powder outlet 47. The classification wheel 42 is located at the top of the air classifier 4 body. The driving device 43 is connected to the classification wheel 42. The raw material inlet 44 and the secondary air inlet are located on the side of the air classifier 4 body. The fine powder outlet 46 is arranged near the upper part of the air classifier 4 body. The coarse powder outlet 47 is located at the bottom end of the air classifier 4 body.

[0036] In this embodiment, the structural setting of the air classifier 4 is specifically shown. During use, through the adjustment of the air volume at the secondary air inlet 45, the effective separation of fine powder and coarse powder is achieved, facilitating the classified utilization of dolomite dust.

[0037] On the basis of the above embodiment, an additional cylinder 48 is connected to the bottom end of the coarse powder outlet 47. An additional air inlet 481 is arranged on the side of the additional cylinder 48, and a classified discharge port 482 is opened at the bottom.

[0038] Specifically, the additional cylinder 48 has an inverted conical structure.

[0039] In this embodiment, by adding the additional cylinder 48, through the adjustment of the air volume at the additional air inlet 481, the coarse powder at the coarse powder outlet 47 can be classified again, and the fine powder mixed therein can be separated, thereby achieving more refined sorting and facilitating better classified utilization.

[0040] The above are only the preferred embodiments of the present application and are not used to limit the present application.
