Working principle: when the carbon black raw material is conveyed, firstly, one end of the conveying bin 1 far away from the discharging bin 3 is conveyed into the conveying bin 1, the spiral conveying shaft 2 continuously rotates in the conveying bin 1, the carbon black in the conveying bin 1 can be conveyed to the discharging bin 3, the carbon black falls into the discharging bin 3 under the action of dead weight after being conveyed to the discharging bin 3, the carbon black is discharged from the discharging bin 3 and collected after passing through three groups of double roller groups from top to bottom in sequence, the two rotary rollers 6 in each group of double roller groups can realize reciprocating opposite movement under the action of a first driving mechanism and an opposite linkage mechanism, in particular, the first driving mechanism is used for driving the sliding sleeves 8 at two ends of the corresponding rotary rollers 6 to slide reciprocally on the inner wall of the discharging bin 3 through one main rotating shaft 5, the sliding speed of the rotary rollers 6 is higher, and the falling process of the carbon black between the two rotary rollers 6 is ensured, the two rotary drums 6 can slide reciprocally at least twice, namely, carbon black can return and clamp the collided carbon black in time in the falling process of the carbon black between the two rotary drums 6, so that the collided carbon black is collided and crushed, meanwhile, under the action of a opposite linkage mechanism, the sliding sleeves 8 at the two ends of the other rotary drum 6 slide reciprocally synchronously, the two rotary drums 6 are always symmetrical relative to the corresponding vertical central plane of the discharging bin 3, the steering directions of the upper and lower central rotating plates 13 are always opposite under the transmission cooperation of the transmission vertical shaft 14, the fact that when the upper two rotary drums 6 do the motion of being far away from or close to each other, the lower two rotary drums 6 are synchronously close to each other or far away from each other is ensured, and the larger and harder collided carbon black in the carbon black raw material which falls between the upper two rotary drums 6, and under the condition that the caking carbon black can not fall and roll along with the rotation of the rotary drum 6, when the two rotary drums 6 at the upper part are mutually far away, the caking carbon black can fall between the two rotary drums 6 and fall to the two rotary drums 6 at the lower part, meanwhile, due to the fact that the sliding speed of the rotary drums 6 is higher, the two rotary drums 6 can timely return and clamp and collide with the caking carbon black in the falling process of the two rotary drums 6, so that the caking carbon black is collided and broken, the two rotary drums 6 in the lowest double-roller set are used for breaking the falling carbon black for the last time, the interval between the two rotary drums 6 is smaller, so that the falling carbon black after the collision and breaking is carried out on the upper part for the last time, and the carbon black raw materials after the complete breaking treatment are discharged out of the bin 3 and are collected.
The foregoing examples merely illustrate one or more embodiments of the invention, which are described in greater detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
