As shown in Figure 3, Figure 4, described control apparatus comprises that symmetry is located at the upper guide ring 11 on described casing 7 tops, side, and symmetry is located at the basifacial lower guide ring 14 of described casing 7 side,
The thread rod 8 being connected with described chevron pointing stock guide 10 through described upper guide ring 11 and lower guide ring 14 and bottom respectively, on this, guide ring 11 plays respectively effect spacing and guiding with lower guide ring 14, be located at the sliding shim 13 on this thread rod 8, be socketed on described thread rod 8 and one end is connected with described sliding shim 13, the other end with described lower lead ring to 14 springs that are connected 9, the nut 12 that is socketed on described thread rod 8 and is abutted against mutually with described sliding shim 13.By the tensile force of rotating nut 12 regulating springs 9, in the time of 3 material feeding of automatic seal type guide case, under the Action of Gravity Field of finished product mineral aggregate, movable chevron pointing stock guide 10 is to bottom offset, and finished product mineral aggregate is discharged in finished product buffering ore storage bin 4.After discharging, movable chevron pointing stock guide 10 reseals casing 7 under the tension force effect of spring 9, and casing 7 is interior simultaneously can remain certain thickness material, plays material sealing effectiveness, has guaranteed the leak tightness of whole finished product buffering ore storage bin 4.Finished product cushions the dust natural subsidence in ore storage bin 4, thereby has eliminated the main dust source of finished product buffering ore storage bin 4, has guaranteed the cleaner production of whole finished product buffering ore storage bin 4, reduces the pollution of environment.
The principle of work of batch (-type) finished product buffering ore storage bin dust pelletizing system of the present invention is:
In the time of mobile reversible tape machine or mobile unloading miner's truck cloth, first finished product sintering deposit falls into automatic automatic seal type guide case, in the time that the finished product sintering deposit degree of depth in automatic seal type guide case reaches higher than predefined material depth H, in automatic seal type guide case, finished product sintering deposit gravity is greater than the tensile force of spring, finished product sintering deposit compressing chevron pointing stock guide is to bottom offset, thereby finished product sintering deposit is discharged in finished product buffering ore storage bin, after cloth, in the time that the finished product sintering deposit degree of depth in automatic seal type guide case falls back to lower than predefined material depth H, in automatic seal type guide case, finished product sintering deposit and chevron pointing stock guide total force are less than the tensile force of spring, chevron pointing stock guide to top offset again with the casing closure of automatic seal type guide case, in casing, can remain certain thickness finished product sintering deposit simultaneously, play material sealing effectiveness, guarantee the leak tightness of whole finished product buffering ore storage bin, prevent that the dust in ore storage bin from emerging from receiving opening, in automatic seal type guide case, predefined material depth H can realize by the nut at regulating spring top.
Simultaneously, in the time of mobile reversible tape machine or mobile unloading miner's truck cloth, can produce a small amount of dust at funnel place, under the draft effect of bag dust collector induced draft fan, dusty gas enters filter chamber by lower open formula flange, dust gas filters through filter bag, dust detention is in filter bag surface, and pure qi (oxygen) directly enters atmosphere to air-purifying chamber by blower fan through sack.When the dust on filter bag surface constantly increases, while causing equipment resistance to rise to setting value, time relay (or differential pressure controller) output signal, program control instrument is started working, and unbalanced pulse valve one by one makes pressurized air carry out jetting deashing by spout to filter bag, filter bag is expanded suddenly, under the effect of back draught, the dust that invests filter bag surface hightails filter bag, returns on mobile reversible tape machine or mobile unloading miner's truck feed adhesive tape.
Novel structure of the present invention, simple and convenient operation and maintenance, good dedusting effect, capital expenditure is few, saves the energy.
