Problems solved by technology

[0003] However, with the continuous increase of calcination capacity, the layout length of the tank furnace is also getting longer and longer, so the crushing unit is also lengthened.
Due to the existence of manufacturing tolerances and installation errors, as the length of the crushing unit increases, the cumulative error becomes very large, resulting in the out-of-synchronization of the ratchet wheels that drive the crushing rollers (some have two teeth, some have three teeth)
In this way, the discharge speed of the three-tooth crushing box is accelerated, resulting in insufficient residence time of petroleum coke in the furnace and waste products

Embodiment Construction

[0016] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited by the embodiments.

[0017] Such as figure 1 , Shown in 2 and 3, the horizontal pull rod 2 can move left and right in the pull rod guide 1. One end of each rocker lever 3 is connected with the horizontal pull rod 2, and the other end is connected with each ratchet lever 4. The ratchet 6 and the ratchet 7 that is connected at the other end of the ratchet lever 4 form a ratchet pair that can drive the crushing roller 8 in each crushing box 5 to rotate. When the horizontal pull bar 2 moved to the left, each ratchet lever 4 rotated counterclockwise around the center under the promotion of each rocker lever 3, and at this moment, the ratchet 6 just slid on the ratchet 7. When the horizontal pull bar 2 moved to the right, each ratchet lever 4 rotated clockwise around the center under the p...

Abstract

The invention discloses a method and a structure for ensuring synchronization of notch wheels of a reciprocating material pulverizing machine, which solve the synchronization problem of the notch wheels of the reciprocating material pulverizing machine. The method comprises enabling the angular speeds of the notch wheels to be the same by adjusting the length of a rocking lever. The invention further discloses a structure through which the method is realized, wherein the rocking lever is provided with a length adjusting device. The length adjusting device consists of a rocking lever bolt, a rocking lever nut and a securing nut. The length of the rocking lever is adjusted through the screw-in depth, in the rocking lever bolt, of the rocking lever nut. The condition that the material discharging speed of each pulverizing box is different because of different numbers of notch wheel teeth caused by accumulation error can be prevented. The residence time of petroleum coke inside a tank furnace is ensured, so that guarantee is provided for reliable and stable operation of production.

Description

technical field [0001] The invention relates to a crushing machine structure with an adjustable rocker arm, in particular to a crushing unit under a petroleum coke calcining pot furnace. Background technique [0002] The crushing unit is an important equipment for crushing the petroleum coke calcined by the tank furnace into a certain particle size. Chinese Patent Publication No. CN101745444A discloses a reciprocating crushing machine and a crushing method. The invention discloses a crushing machine, and in particular relates to a reciprocating crushing machine and a crushing method. The structure of the reciprocating shredder is as follows: the output end of the transmission device is connected to the eccentric wheel device, the output end of the eccentric wheel device is connected to the horizontal pull rod that can only move horizontally and linearly, and the horizontal pull rod is connected to each ratchet rod through the rocker rod. Each ratchet lever drives its own cr...
