Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolysis technology, specifically to a coarse crushing mechanism for carbon slag. Background Technology

[0002] Carbon slag is an unavoidable solid waste in the electrolytic aluminum production process. It is the waste residue produced when carbon blocks that peel off from the anode fall into the molten electrolyte and float on its surface during the electrolytic aluminum production process. Its main components are carbon and electrolyte.

[0003] Because the slag is agglomerated, it needs to be initially crushed before being fed into the rotary kiln. Currently, the primary crushing of the slag is done by manual hammering, which is not only inefficient but also increases the labor intensity of workers. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a coarse crushing mechanism for charcoal slag, which can effectively reduce the labor intensity of workers and improve the coarse crushing efficiency of charcoal slag, thus effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coarse crushing mechanism for charcoal slag, comprising:

[0007] A turntable is disposed above the base, and the turntable is rotatable relative to the base;

[0008] A drive rotation mechanism is located at the lower end of the base and is used to control the reciprocating rotation of the turntable;

[0009] The shell-breaking mechanism is located on one side of the turntable and faces the box containing the whole piece of charcoal slag. Under the reciprocating rotation of the turntable, it strikes the center part of the whole piece of charcoal slag and breaks it.

A bearing is provided between the rotating shaft and the base.

[0013] In a preferred embodiment of this invention, the rotating shaft and the fixing rod are connected by welding.

[0014] As a preferred technical solution of this utility model, the shell-breaking mechanism includes a fixed plate, an upper connecting rod, a lower connecting rod, a connecting block, a hydraulic cylinder, a shell-breaking machine, and a shell-breaking machine head;

[0015] The fixed plates are symmetrically fixed to one side of the turntable. Two upper connecting rods and two lower connecting rods are respectively arranged between the two fixed plates.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments (for ease of description and understanding, hereinafter referred to as...). Figure 3 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a coarse crushing mechanism for charcoal slag, including a base 1, a turntable 2, a drive rotation mechanism 3, and a shell-breaking mechanism 5;

[0024] The base 1 is set on one side of the box containing the whole piece of charcoal slag. The upper end of the box has an opening. Support legs 6 are evenly distributed around the lower surface of the base 1. The turntable 2 is set above the base 1. The lower end of the turntable 2 does not contact the upper surface of the base 1. The turntable 2 can rotate relative to the base 1.

[0025] The drive rotation mechanism 3 is located at the lower end of the base 1, and the shell-breaking mechanism 5 is located on one side of the turntable 2, facing the box containing the whole piece of charcoal slag. The drive rotation mechanism 3 controls the turntable 2 to rotate back and forth, thereby driving the shell-breaking mechanism 5 to break the charcoal slag along the center line. Since the charcoal slag is relatively brittle, as long as it is hit at the center, the edge will also be broken into pieces.

[0026] Furthermore, in order to reduce the weight of turntable 2 and make it easy to rotate, turntable 2 is a cuboid with a hollow internal structure, and a fixing rod 4 is welded inside turntable 2.

[0027] Furthermore, the drive rotation mechanism 3 includes a drive motor 31, a drive gear 32, a driven gear 33, and a rotating shaft 34. The drive motor 31 is fixed to the lower surface of the base 1, the drive gear 32 is fixed to the output shaft end of the drive motor 31, the driven gear 33 is meshed with one side of the drive gear 32, one end of the rotating shaft 34 is fixedly connected to the driven gear 33, and the other end of the rotating shaft 34 passes through the base 1 and the turntable 2 in sequence and is fixedly connected to the fixed rod 4. A bearing is provided between the rotating shaft 34 and the base 1. The drive motor 31 controls the rotation of the drive gear 32, which in turn drives the driven gear 33 to rotate. Under the action of the rotating shaft 34, the entire turntable 2 is rotated.

[0028] To improve the connection strength between the rotating shaft 34 and the fixed rod 4, the rotating shaft 34 and the fixed rod 4 are connected by welding.

[0029] Furthermore, the shell-breaking mechanism 5 includes a fixed plate 51, an upper connecting rod 52, a lower connecting rod 53, a connecting block 54, a hydraulic cylinder 55, a shell-breaking machine 56, and a shell-breaking machine head 57;

[0030] Fixed plates 51 are symmetrically fixed to one side of the turntable 2. Two upper connecting rods 52 and two lower connecting rods 53 are respectively arranged between the two fixed plates 51. The two upper connecting rods 52 are positioned opposite each other and above each other, while the two lower connecting rods 53 are positioned opposite each other and below each other. One end of each upper connecting rod 52 and lower connecting rod 53 is hinged to a fixed plate 51, and the other end is hinged to a connecting block 54. The upper connecting rods 52, lower connecting rods 53, and connecting block 54 form a [missing information - likely a specific structure or feature]. The four-bar linkage has a connecting block 54 fixedly connected to one side of the shell-breaking machine 56. The lower end of the shell-breaking machine 56 is connected to the shell-breaking head 57. The fixed end of the hydraulic cylinder 55 is fixed between two fixed plates 51. The telescopic end of the hydraulic cylinder 55 is hinged to the pin connecting the two lower connecting rods 53. The hydraulic cylinder 55 is inclined. The shell-breaking head 57 is directly facing the center of the carbon slag. Under the action of the hydraulic cylinder 55, the shell-breaking mechanism 57 contacts the carbon slag and continues to crush the carbon slag downwards.

[0031] The hydraulic cylinder 55 has its input end connected to the hydraulic pump via a pipeline, and one end of the hydraulic pump is connected to the hydraulic oil tank via a pipeline. The input ends of the hydraulic pump, drive motor 31, and shell-breaking machine 56 are electrically connected to the output ends of the external control switch, respectively.

[0032] In use: After placing the charcoal slag into the box, start the hydraulic cylinder 55. The telescopic end of the hydraulic cylinder 55 extends, thereby pushing the shell-breaking head 57 downward to contact the charcoal slag. At this time, start the shell-breaking machine 56 to control the shell-breaking head 57 to continuously strike the charcoal slag, breaking it into small pieces. Then, start the drive motor 31, which drives the turntable 2 to rotate under the meshing transmission of the drive gear 32 and the driven gear 33. By controlling the forward and reverse rotation of the drive motor 31, the turntable 2 makes reciprocating rotational motion, causing the shell-breaking head 57 to swing near the center line of the charcoal slag, striking and breaking it.

[0033] This invention can achieve preliminary crushing of charcoal slag. By using the shell-breaking mechanism 5 to continuously strike the charcoal slag, it can be crushed, reducing the labor intensity of workers. By driving the rotating mechanism 3 to control the shell-breaking mechanism 5 to swing back and forth, the striking area can be expanded, thereby enhancing the crushing effect.
