Problems solved by technology

[0006] (1) The actual position of the unqualified large pellets in the disc of the pelletizing machine is not fixed. Sometimes the unqualified large pellets may appear in a position in the disc, and sometimes the unqualified large pellets The pellets appear in another position of the disc. When crushing, according to the actual production situation, the crushing area should be set at the position where the unqualified large pellets appear for crushing, so as to achieve the best crushing efficiency, and the above patents The crushing device is fixedly installed above the disc. When crushing, the crushing area is fixed. In this way, the crushing device in the above patent cannot flexibly adjust its crushing area according to the actual production situation, so as to achieve best crushing efficiency;

Embodiment 1

[0035] Example 1: A method for producing large suppressed pellets suitable for a disc pelletizer is to use a large suppressed pellet generating device set near the disc of the pelletizer to crush unqualified large pellets. According to the actual position of the unqualified large pellets generated in the pelletizing machine disc, by adjusting the position of the restraining rod device of the restraining large pellet generating device, the restraining rod device can be blocked in the pelletizing machine. At the lower half of the disc and at the position facing the unqualified large pellets, the unqualified large pellets are driven by the rotating pelletizer disc to hit the restraining rod device, and the unqualified pellets The big pellets shattered.

[0036] Such as figure 1 As shown, the device for suppressing large pellet generation includes a control platform 1; a support frame 2, which is fixedly arranged on the control platform 1; a trolley support 3, which is rotatably conn...

Embodiment 2

[0044] Example 2: Such as Picture 10 with Picture 11 As shown, compared with Embodiment 1, the difference is: when the lateral movement control mechanism is a hydraulic transmission mechanism or a pneumatic transmission mechanism, it includes a cylinder support block 23, which is arranged on the horizontal support plate 31 The transverse cylinder or transverse hydraulic cylinder 24, which is fixedly arranged on the cylinder support block 23; the connecting part 12 on one end of the trolley body is connected to the longitudinal cylinder body fixedly arranged on one end of the trolley body 51 The longitudinal cylinder connecting block is fixedly connected with the piston of the transverse cylinder or the transverse hydraulic cylinder 24. The trolley 5 is driven to slide back and forth along the guide rail 11 by the transverse cylinder or the transverse hydraulic cylinder 24.

[0045] The longitudinal lifting control mechanism is a hydraulic transmission mechanism or a pneumatic t...

Abstract

The invention discloses a method for inhibiting the generation of large pellets and suitable for being used in a disk pelletizer. The unqualified large pellets are crushed by equipment for inhibiting the generation of the large pellets and arranged adjacent to a pelletizer disk by adjusting the position of an inhibiting rod device of the equipment for inhibiting the generation of the large pellets according to the actual positions of the unqualified large pellets generated in the pelletizer disk, blocking the inhibiting rod device on the lower half part of the pelletizer disk and the positions opposite to those of the unqualified large pellets and driving the unqualified large pellets to impact onto the inhibiting rod device through the rotary pelletizer disk. According to the method, the unqualified large pellets are crushed according to the actual positions of the unqualified large pellets generated in the pelletizer disk. The method is high in crushing efficiency and safety and strong in practicability.

Description

Technical field [0001] The invention relates to a method for inhibiting the formation of large pellets, in particular to a method for inhibiting the formation of large pellets suitable for a disc pelletizing machine, and belongs to the technical field of iron ore powder pelletizing. Background technique [0002] Disc pelletizing machine is used to pelletize iron ore powder. It is one of the main supporting equipment of various pelletizing plants. The coke powder, limestone powder (or quicklime) and iron ore powder are mixed in the mixer, and then input to the feeding device on the upper part of the disc pelletizing machine, and the feeding device is uniformly fed to the pelletizing machine. The spray water is supplied by the spray device. The obliquely arranged pelletizing machine disc is rotated by mechanical transmission. The mixture and spray water are rolled into balls in the pelletizing machine disc. The produced pellets fall from the pelletizing machine disc to the conveyo...
