Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of the high-efficient powder concentrator with meal sorting unit of the present invention;
Fig. 3 is the profile of A-A direction in Fig. 2.
Wherein, elevator 1, V-type powder concentrator 2, steady feed bin 3, roll squeezer 4, the high-efficient powder concentrator 5 with meal sorting unit, cyclone cylinder 6, circulating fan 7, ball mill 8, bag filter 9, system fan 10, material pneumatic entrance 51, meal sorting unit 52, lower blast pipe 53, cage type powder 54, finished gas-flow outlet 55, one-level coarse fodder outlet 56, secondary coarse fodder outlet 57.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail.
As shown in Fig. 1～2, roll squeezer 4 pregrinding systems, comprise elevator 1, V-type powder concentrator 2, steady feed bin 3, roll squeezer 4, the high-efficient powder concentrator 5 with meal sorting unit 52, cyclone cylinder 6, circulating fan 7, bag filter 9, ball mill 8 and system fan 10.Wherein, V-type powder concentrator 2, steady feed bin 3 are connected successively with roll squeezer 4, thereby and the material outlet of roll squeezer 4 is communicated with formation by elevator 1 and circulates with V-type powder concentrator 2, the outlet of V-type powder concentrator 2 is connected with the high-efficient powder concentrator 5 with meal sorting unit 52.This high-efficient powder concentrator comprises cage type powder 54 and meal sorting unit 52, meal sorting unit 52 is located at the bottom of cage type powder 54 by lower blast pipe 53, side at meal sorting unit 52 tangentially arranges material pneumatic entrance 51, and the outlet of the coarse fodder of bottom exports 56 as one-level coarse fodder, and be connected with steady feed bin 3 by pipeline; And cage type powder 54 comprises finished gas-flow outlet 55 and secondary coarse fodder outlet 57,57 of secondary coarse fodder outlets are connected with ball mill 8, and air stream outlet is connected with bag filter 9 with cyclone cylinder 6 successively.
During work, after 2 pairs of materials of V-type powder concentrator select powder to process, coarse fodder enters roll squeezer 4 through steady feed bin 3 to carry out roll extrusion and mills, and the material after roll extrusion enters V-type powder concentrator 2 by elevator 1 circulation and further selects powder to process; First the material pneumatic entrance 51 that enters meal sorting unit 52 from V-type powder concentrator 2 outlet relatively thin material out through its for the first time after sorting process in meal and fine powder enter cage type powder 54, and get back to steady feed bin 3 from one-level coarse fodder outlet 56 meal out, cage type powder 54 carries out sorting process for the second time again, middle meal is carried out to separation and send and enter ball mill 8 and obtain finished cement under the effect of ball mill 8 from secondary coarse fodder outlet 57; And powder material sends into cyclone cylinder 6 again and carry out separation, the qualified fine powder of screening is selected directly as finished cement, and cyclone cylinder 6 is sent into the shunting of carrying dust bag filter 9 and gathered dust and obtain finished cement under the effect of circulating fan 7.The air-flow of processing through bag filter 9 in the effect of system fan 10 to whole system air feed.
In sum, through the material of roll squeezer 4 extruding after V-type powder concentrator 2, high-efficient powder concentrator 5 with meal sorting unit 52, the meal feed bin 3 that stabilizes, more brought into play the effect of roll squeezer 4, middle meal and fine powder enter high-efficient powder concentrator body, qualified fine powder is selected directly as finished cement, improved system throughput, reduced system energy consumption, alleviated the interior grinding phenomenon of crossing of ball milling simultaneously, the further grinding of middle meal return of serve mill, ball milling can improve the sphericity of cement powders, reduces cement water requirement.
