Description

Technical Field

[0001] This utility model relates to the field of residual electrode cleaning technology, specifically to a residual electrode electrolyte pre-crusher. Background Technology

[0002] The main component of the anode is carbon, and it is an essential replacement consumable in the aluminum electrolysis cell of an aluminum electrolysis plant for smelting alumina into molten aluminum. The smelting process in the aluminum electrolysis cell needs to be carried out at a high temperature of 950℃~970℃. The electrolyte is a material that covers the carbon block of the anode to keep it warm. This material is mainly composed of electrolyte, alumina powder and other components. It completely covers the anode in a crust-like state to ensure that the hot air flow inside the electrolysis cell does not escape.

[0003] The anodes consumed during aluminum electrolysis are called residual anodes. After being replaced from the electrolysis cell, they need to be separated and recycled in the anode assembly workshop, including the electrolyte, carbon blocks, and steel claws. Because the electrolyte forms a hard crust covering the carbon blocks and steel claws, it is difficult to break up and clean the electrolyte between the steel claws using an automatic electrolyte cleaning machine. Manual breaking and cleaning is often required, which is labor-intensive. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a pre-crusher for residual electrolyte, which has a simple structure, occupies little space, and enables hammer crushing of residual electrolyte covering material.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a residual electrolyte pre-crusher, including a base, a sealing cover on the base, a through channel at the top of the sealing cover, a lifting mechanism installed on the base directly below the channel, and crushing mechanisms symmetrically arranged on both sides of the lifting mechanism.

[0006] The crushing mechanism includes a vertical frame, a rotating arm, a hydraulic cylinder, and a breaker hammer. The vertical frame is mounted on a base. The bottom of the rotating arm is hinged to the vertical frame, and the top is connected to the breaker hammer. The cylinder barrel of the hydraulic cylinder is hinged to the vertical frame, and the piston rod of the hydraulic cylinder is hinged to the middle of the rotating arm.

[0007] The breaker is a hydraulic breaker or a pneumatic breaker.

[0008] The top of the sealing cover is equipped with a dust collection port.

[0009] The sealing cover has double doors at both ends.

[0010] The elevator is a scissor lift.

[0011] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model has a simple structure and occupies little space. It achieves pre-crushing of the electrolyte covering material of the residual electrode by hammering through the crushing mechanism, and adopts a lifting platform to meet the needs of pre-crushing residual electrodes of different heights.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0018] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments. Example

[0019] like Figures 1 to 3 As shown, this utility model provides a pre-crusher for residual electrolyte, including a base 1, a sealing cover 2 on the base 1, a channel for guide rod 3 and residual electrode 4 to pass through the top of the sealing cover 2, a lifting machine 5 is set directly below the channel and installed on the base 1, and crushing mechanisms are symmetrically arranged on both sides of the lifting machine 5.

[0020] Specifically, the crushing mechanism includes a frame 6, a rotating arm 7, a hydraulic cylinder 8, and a breaker hammer 9. The frame 6 is mounted on the base 1. The bottom of the rotating arm 7 is hinged to the frame 6, and the top is connected to the breaker hammer 9. The cylinder of the hydraulic cylinder 8 is hinged to the frame 6, and the piston rod of the hydraulic cylinder 8 is hinged to the middle of the rotating arm 7. The breaker hammer 9 is a hydraulic breaker hammer or a pneumatic breaker hammer. The lifting platform 5 is a scissor lift.

[0021] When the electrolyte-covered residual electrode 4 runs to the electrolyte pre-crusher, the elevator 5 rises to contact the residual electrode 4 and places it at a suitable height. The hydraulic cylinder 8 of the crushing mechanism retracts, driving the rotating arm 7 and the breaker hammer 9 to move downward. When the chisel of the breaker hammer 9 contacts the electrolyte of the residual electrode, the breaker hammer 9 starts to crush the electrolyte. After the electrolyte is crushed, the hydraulic cylinder 8 extends, driving the rotating arm 7 and the breaker hammer 9 back to their original positions.

[0022] Furthermore, the top of the sealing cover 2 is provided with a dust collection port 10, through which the dust generated during the crushing process is collected, thus avoiding the unorganized emission of dust.

[0023] Furthermore, to facilitate equipment maintenance, the sealing cover 2 is provided with double doors 11 at both ends.

[0024] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
