Abstract
The utility model discloses a primary sieving device of a crusher, which comprises a frame. The frame is provided with a primary sieving chamber, the top and the bottom of the primary sieving chamber are respectively provided with an inlet and an outlet, the inlet of the primary chamber is provided in parallel with a plurality of rotary delivery screen rolls the delivery directions of which face to the edge of one side of the primary sieving chamber, a gap through which the material blocks with qualified volume can pass is arranged between the adjacent delivery screen rolls, and each delivery screen roll is driven by a drive mechanism fixed on the frame through a transmission mechanism. When the primary sieving device is used together with the crusher, most of coal briquettes accordant with the demand can drop from the gap between the adjacent delivery screen rolls directly and fall into the outlet, the rest coal briquettes with larger volume are driven by the rotary delivery screen rolls to be delivered to the crushing chamber and crushed, because the materials are sieved primarily in the primary sieving chamber, the materials are separated, thereby the stoppage in the prior crusher is effectively reduced, and the crushing ability of the whole crusher is improved.
Description
Technical field
The utility model relates to disintegrating apparatus, especially the elementary screening plant of disintegrating machine.
Background technology
Be provided with a pair of breaker roll in the crushing chamber of the existing disintegrating machine that is used for the raw coal fragmentation, two breaker roll upper edges are axially arranged with the gear teeth, material is poured directly on the feeding mouth of crusher chamber when work, coal cinder not of uniform size falls together, its broken classification is to realize in crusher chamber, the bulk raw coal roller that is broken beats pulverizing, pulverizes the piece material that requires and directly falls to discharging from blanking port and meet; The problem that existing disintegrating machine exists is: when the bulk raw coal is mingled with under the bigger situation of fritter and raw coal continuous flow, the fritter raw coal can not in time be discharged and can be produced jam, when the humidity of coal was big, wet in a large number coal can stick between two groups of gear teeth, also can produce jam.
The utility model content
The purpose of this utility model is to provide a kind of and can be before pulverizing material be carried out elementary screening and with the elementary screening plant of the disintegrating machine of qualified material shunting.
The technical solution of the utility model is: the elementary screening plant of disintegrating machine, comprise frame, described frame is provided with the primary dcreening operation chamber, primary dcreening operation chamber top and bottom ends has respectively into, discharging opening, in the feeding mouth of primary dcreening operation chamber, be provided with the conveying sieve roller of a plurality of rotating throughput directions side by side towards the edge of primary dcreening operation chamber one side, but be provided with the gap that the long-pending qualified material piece of donor passes through between each adjacent conveyor sieve roller, each carry sieve roller by transmission mechanism by the drive mechanism that is fixed on the frame.
Described each carry roll shaft one end of sieve roller to be equipped with travelling gear, engaged transmission is equipped with carrier gear between the adjacent travelling gear, carry in the sieve roller one of them carry the roll shaft of sieve roller by being fixed on motor-driven on the frame.
The utility model is with the supporting use of disintegrating machine the time, primary dcreening operation chamber adjacency is arranged on feeding mouth one side of the pulverizing chamber of disintegrating machine, owing to adopted the rotational conveyance structure of conveying sieve roller arranged side by side on the primary dcreening operation chamber, material enters crushing chamber again after carrying the elementary screening of sieving roller on the primary dcreening operation chamber, most of satisfactory coal cinder can directly leak down from the gap between the adjacent conveyor sieve roller and fall into discharging opening, the material that remaining volume is bigger is admitted to pulverizing chamber soon and carries out fragmentation under the drive of the conveying sieve roller that rotates, because material has carried out elementary screening in the primary dcreening operation chamber and with material diversion, like this under the situation that does not influence overall mass flow, mass flow in the pulverizing chamber diminishes, thereby can effectively reduce the jam that existing disintegrating machine exists, improve the breaking capacity of disintegrating machine complete machine.
Description of drawings
Fig. 1 is that the utility model is applied in the structural representation on the disintegrating machine;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As shown in Figure 1, disintegrating machine comprises frame 14, frame 14 is provided with crushing chamber 2, be provided with the breaker roll 3 that has the gear teeth in the crushing chamber 2,4, breaker roll 3,4 respectively by being fixed on motor 11 on crushing chamber 2 machine frame at two sides, 12 drive, elementary screening plant of the present utility model comprises the primary dcreening operation chamber 1 of the side that is arranged at crushing chamber 2, the top of primary dcreening operation chamber 1 and crushing chamber 2 is provided with the feeding mouth that adjoins each other, ecto-entad is provided with the conveying sieve roller 7 of a plurality of throughput directions towards crushing chamber side by side in the feeding mouth of primary dcreening operation chamber 1, but be provided with the gap that the long-pending qualified material piece of donor passes through between each adjacent conveyor sieve roller 7, each carries roll shaft one end of sieve roller 7 to be equipped with travelling gear 5, engaged transmission is equipped with carrier gear 6 between the adjacent travelling gear 5, one of them carry the roll shaft of sieve roller 7 motor 8 drive on the frame 14 by being fixed on, the bottom of primary dcreening operation chamber 1 and crushing chamber 2 is equipped with discharging opening, and the discharging opening of primary dcreening operation chamber 1 and crushing chamber 2 bottoms all feeds in total discharging opening 13 of disintegrating machine bottom.
Disintegrating machine of the present utility model is installed when work, material is admitted under the drive of the conveying sieve roller 7 of the rotation on 1 top, primary dcreening operation chamber and carries out fragmentation in the crushing chamber 2, in the process that material is advanced on carrying sieve roller 7, directly fall in the slit of the qualified material piece of volume between adjacent conveyor sieve roller 7 and with crushing chamber 2 broken good material piece discharge from total discharging opening 13 in the lump, the material of the needs fragmentation that volume is bigger is admitted to pulverizing chamber 2 soon and carries out fragmentation under the drive of roller 7 is sieved in the conveying of rotating.
Claims (2)
1, the elementary screening plant of disintegrating machine, comprise frame, it is characterized in that: described frame is provided with the primary dcreening operation chamber, primary dcreening operation chamber top and bottom ends has respectively into, discharging opening, in the feeding mouth of primary dcreening operation chamber, be provided with the conveying sieve roller of a plurality of rotating throughput directions side by side towards the edge of primary dcreening operation chamber one side, but be provided with the gap that the long-pending qualified material piece of donor passes through between each adjacent conveyor sieve roller, each carry sieve roller by transmission mechanism by the drive mechanism that is fixed on the frame.
