Description

Aluminum electrolysis waste cathode carbon block crushing die

Technical Field

The utility model belongs to the technical field of aluminium electroloysis waste cathode carbon block is handled, concretely relates to broken mould of aluminium electroloysis waste cathode carbon block.

Background

In the aluminum electrolysis production process, a large amount of waste cell linings are generated when an electrolytic cell is overhauled, and massive carbon blocks and heat insulation materials need to be crushed before the waste cell linings are subjected to harmless treatment. The upper die and the lower die in the existing mature pressure equipment are more in planes, and in the actual production process, the efficiency of crushing the carbon blocks is very low, so that the production requirement can not be well met.

Disclosure of Invention

The utility model discloses an aim at just in order to solve the problem that above-mentioned prior art exists, provide a crushing efficient, the reliable broken mould of useless negative pole charcoal piece of simple structure.

The purpose of the utility model is realized through the following technical scheme:

an aluminum electrolysis waste cathode carbon block crushing die comprises an upper die and a lower die; the upper die comprises an upper die main body with a square section, round steel welded on the bottom surface of the upper die main body in a dot matrix manner, and a group of parallel inverted T-shaped hanging grooves formed in the top of the upper die main body; the lower die comprises a square section lower die main body corresponding to the peripheral size of the upper die main body, a grid processed at the top of the lower die main body and a group of material guide grooves processed below the grid and penetrating through two opposite side surfaces of the rectangular frame; the round steel of the upper die is used as a pressure head to correspond to the grid of the lower die, and the round steel can be inserted into the grid when the upper die is pressed down.

The external diameter of the round steel welded on the bottom surface of the main body is 60mm, and the height is 70 mm. The grid is processed on the top of the lower die main body, and the top surface of a grid frame of the grid is a cutting edge surface processed with a chamfer.

The utility model discloses weld in the round steel that the dot matrix of last mould bottom set up and constitute a set of convex pressure head, the grid of lower mould constitutes a set of vertically and horizontally staggered's blade, and the pressure head can correspond during the grid of impressing, with the crushing of big piece useless negative pole charcoal piece high-efficiently, crushing efficiency is high. The utility model discloses simple structure is reliable, and lower mould formula structure as an organic whole goes up the mould main part also formula structure as an organic whole, and rigidity and intensity are good, and are not fragile.

Detailed Description

The invention is further illustrated by the following figures and examples.

An aluminum electrolysis waste cathode carbon block crushing die comprises an upper die 1 and a lower die 2. The upper die 1 comprises an upper die main body 11 with a square section, round steel 12 welded on the bottom surface of the upper die main body 11 in a dot matrix manner, and a group of parallel inverted T-shaped hanging grooves 13 formed in the top of the upper die main body 11, as shown in fig. 1 and 2. The round steel 12 welded on the bottom surface of the main body 11 has an outer diameter of 60mm and a height of 70 mm. As shown in fig. 3 and 4, the lower mold 2 includes a lower mold body 21 with a square cross section corresponding to the same peripheral dimension of the upper mold body 11, a grid 22 formed on the top of the lower mold body 21, and a set of material guiding chutes 23 formed below the grid and penetrating through two opposite side surfaces of the rectangular frame. The round steel 12 of the upper die is used as a pressure head to correspond to the grid of the lower die, and the round steel can be inserted into the grid when the upper die is pressed down. The grid 22 processed on the top of the lower die main body and the cutting edge surface 24 processed with a chamfer are arranged on the top surface of the grid frame of the grid, so that the waste cathode carbon block is crushed. The upper die main body 11 is cast by cast steel, and round steel 12 is welded on the bottom surface of the crushed waste cathode carbon block after the upper die main body is cast. An inverted T-shaped hanging groove 13 is formed in the top of the upper die main body to reserve a position for bolting to the press, and the upper die main body 11 is mounted to the press 4 by a connecting bolt 3 passing through the inverted T-shaped hanging groove 13 as shown in fig. 5. The lower die main body is cast by cast steel, the grid 22 and the material guide groove 23 are directly processed on the lower die main body, and the whole lower die is of an integrated structure, so that the rigidity and the structural strength of the lower die can be ensured.

As shown in fig. 5, the large waste cathode carbon blocks are conveyed to the lower die 2 by the waste cathode carbon block pushing device of the upper stage, the field personnel operate the press machine 4 to drive the upper die 1 to press downwards, and the waste cathode carbon blocks are crushed by the upper die and then fall into the material guide groove 23. As shown in fig. 6, a horizontal pushing device 5 with a pushing plate 51 at the front end is additionally arranged, which can be inserted into the material guiding groove from the outside, and pushes the broken waste cathode carbon blocks falling into the material guiding groove out of the material guiding groove and falls onto a conveying device arranged subsequently.
