Detailed description of the invention
In the present embodiment, the continuous method for mixing of granular material is the combination mixing method that adopts two-stage mechanical agitation broken group batch mixing and one-level strength homogenizing batch mixing.Combination mixing method is to enter in proportion the material of mixing device simultaneously, completes batch mixing process continuously from top to bottom according to gravity through the broken group of first order mechanical agitation batch mixing, second level mechanical agitation broken group batch mixing and bottom strength homogenizing batch mixing.
Referring to Fig. 1, Fig. 2 and Fig. 3, in the present embodiment, the version of the continuous mixing device of granular material is:
Mixing device is set to vertical structure, the aggregate bin 1 that is used for two or more granular material charging is arranged on the top of described mixing device, be positioned at described aggregate bin 1 below, be on same central axis position, set gradually from top to bottom: one-level mixing chamber 3, be connected to blanking channel 7, the secondary mixing chamber 8 between one-level mixing chamber 3 and secondary mixing chamber 8 and be undertaken on the strength levelling chamber 16 of the below of secondary mixing chamber 8, blanking channel 7 can be twice or multiple tracks, and each road blanking channel is arranged along even circumferential.
In concrete enforcement, corresponding structure setting also comprises:
In described one-level mixing chamber 3, be undertaken on aggregate bin 1 below, be and be horizontally disposed with the spreading disk 5 being driven by spreading motor 6, spreading disk stirring vane 41 is set in the card of described spreading disk 5, the rotating shaft of spreading disk 5 extends upwardly in the tremie pipe 2 of aggregate bin 1, and tremie pipe stirring vane 42 is installed, so that batch mixing and blanking smoothly.
In described secondary mixing chamber, be and be horizontally disposed with the batch mixing dish 10 with batch mixing blade 12 being driven by batch mixing motor 11, ring-type spreading grid 13 are set in the periphery of described batch mixing dish 10, and the vertical fence in described ring-type spreading grid 13 is clava 14 (as shown in Figures 2 and 3).
Be provided with strength homogenizing bed 17 in the bottom of strength levelling chamber 16, described strength homogenizing bed 17 is for being covered with the air permeable plate of air-flow through hole, and compressed air imports strength levelling chamber 16 by air supply pipe 18 the air-flow through hole on described strength homogenizing bed 17; By changing the realization of compressed-air actuated air pressure size, the material on homogenizing bed is carried out to homogenizing, stirring and wriggling.
Between one-level mixing chamber 3 and secondary mixing chamber 8, burden-guiding cone 9 is set, described burden-guiding cone 9 tops are undertaken on the bottom of blanking channel 7 in one-level mixing chamber, and the bottom cone mouth of burden-guiding cone 9 is docked at the central authorities of batch mixing dish 10 in described secondary mixing chamber.
In strength levelling chamber 16, the top that is positioned at described strength homogenizing bed 17 arranges material controlling cone 15 down at a gulp; Material controlling is bored not only for guide, also have in the time that bottom material stream seethes with excitement under strength effect and control the effect that material upwards flows, correspondingly, strength homogenizing bed 17 be set to tapering slightly towards centroclinal inclined-plane;
Discharging opening is positioned at strength homogenizing Chuan center, and discharge nozzle 19 is plugged in discharging opening; Discharge nozzle 19 is set to version that can be flexible up and down, and the height stretching out in discharging opening by adjusting discharge nozzle 19, realizes the automatic overflow of material on strength homogenizing bed 17.
Operation principle:
Two or more granular material enters the aggregate bin 1 of batch mixer top by proportioning, after material stream merges, enter one-level mixing chamber 3 through tremie pipe 2; Material is fallen on spreading disk 5, and spreading disk 5 is fast rotational under the driving of spreading motor 6; Fall material on spreading disk 5 and disperseed rapidly and interpenetrate under the effect of spreading disk stirring vane 41, the caking that simultaneously may wrap in material or material group are broken, and material completes mechanical premixed process in one-level mixing chamber.
Material after premixed enters secondary mixing chamber 8 by blanking channel 7 and burden-guiding cone 9, fall on the batch mixing dish 10 being located in secondary mixing chamber, batch mixing dish 10 is fast rotational under the driving of batch mixing motor 11, batch mixing dish 10 is provided with batch mixing blade 12, the material of falling batch mixing Pan10 center under centrifugal action along the radial motion of batch mixing blade 12, leave fast batch mixing dish 10 and pass the ring-type spreading grid 13 that are fixed on secondary mixing chamber inwall, ring-type spreading grid 13 are made up of the clava 14 of some longitudinal layouts, play and disperse and the change material particles direction of motion, reduce the corrasion of mixing chamber inwall, material completes mechanical type mixed process at secondary mixing chamber.
Under the acting in conjunction of batch mixing dish 10 and secondary mixing chamber 8 internal negative pressure environment, material is forced to be controlled in the region that is provided with clava 14, drops on the outward flange of strength homogenizing bed 17 through the outward flange of material controlling cone 15 and the inwall of strength levelling chamber 16.The material of falling on strength homogenizing bed 17 outward flanges is fluidized state under compressed-air actuated effect, and is collected to the discharging opening that is arranged on strength homogenizing Chuan17 center by the outward flange of strength homogenizing bed 17, automatically draws off through discharge nozzle 19.
