Technical Field

[0001] The utility model discloses a carbon slag transport auxiliary tool, in particular to a carbon slag hole device at an aluminum tapping end for electrolytic aluminum, belonging to the technical field of electrolytic aluminum. Background Art

[0002] In the actual production of electrolytic aluminum, the electrolytic cell continuously consumes the slag of the anode carbon block through continuous electrochemical reactions, and carbon slag is continuously produced, which leads to an increase in the electrolyte pressure drop in the cell, and an increase in the cell temperature and voltage. Therefore, workers are required to salvage the carbon slag continuously, but the traditional carbon slag cleaning construction requires salvaging the carbon slag and then transporting it by cart. The disadvantages of this method are: 1. Workers need to transport it over long distances, 2. Due to the special nature of the cart, it is impossible to transport it on a large scale, which greatly increases the workload of workers; and because workers spend most of their time transporting carbon slag, the carbon slag cannot be cleared out of the cell in time, which can easily cause the electrolytic cell to become diseased, which will seriously damage the cell's electrical efficiency in the long run, and is not conducive to the smooth and efficient production and operation of the electrolytic cell.

[0009] The slag discharge pipe and the slag discharge bucket are both made of tungsten steel alloy.

[0018] The utility model is further explained and illustrated below in conjunction with the accompanying drawings:

[0019] For example, see Figure 1-Figure 2 A carbon slag hole device for aluminum electrolysis end includes a slag discharge pipe 1, a slag discharge bucket 2 and a cover plate 5. The slag discharge bucket 2 is arranged at the lower end of the slag discharge pipe 1, the cover plate 5 is arranged at the end of the slag discharge bucket 2, a handle 6 is arranged on the outer wall of the cover plate 5, a support 8 is arranged below the handle 6, and a rotating clamping plate 7 is arranged above the support 8. The end of the rotating clamping plate 7 is rotatably connected to the side wall of the slag discharge bucket 2.

[0020] The ends of the handle 6 and the support 8 extend out of one side of the hopper 2 respectively, and an arc-shaped groove is provided at the bottom of the rotating clamping plate 7 at a position corresponding to the support 8.

[0021] The cross section of the cover plate 5 is larger than the cross section of the outlet end of the slag hopper 2 , and the upper end of the cover plate 5 is hinged to the upper part of the outlet end of the slag hopper 2 .

[0022] The slag discharge pipe 1 is communicated with the interior of the slag discharge bucket 2. A plug plate 3 is arranged on the back of the slag discharge bucket 2. Positioning steel bars 4 are respectively arranged on both sides of the lower middle part of the slag discharge bucket 2. The positioning steel bars 4 are distributed in an L shape.

[0023] Positioning grooves 9 are respectively arranged on the two side surfaces of the slag discharge pipe 1 , and insertion holes 10 are correspondingly arranged on the inserting plate 3 outside the positioning grooves 9 , and positioning bolts 11 are connected between the insertion holes 10 and the positioning grooves 9 through threads.

[0024] The slag discharge pipe 1 and the slag discharge bucket 2 are both made of tungsten steel alloy.

[0025] The cover plate 5 is made of high temperature resistant alloy material.

[0026] The angle between the slag discharge pipe 1 and the slag discharge bucket 2 is 120°.

[0027] In the above description, there are two positioning steel bars distributed in an L shape. When in use, the positioning steel bars are stuck in the floor to prevent the device from shifting and contacting the busbar around the groove.

[0028] In the above description, the upper end of the cover plate is hinged to the upper part of the slag hopper port, and the lower end of the cover plate is fixed by rotating the clamping plate.

[0029] In the above description, the plug plate is L-shaped and directly inserted into the gap of the busbar. The slag pipe runs through the space between the floor and the busbar and is fixed to the socket on the plug plate by positioning bolts, so that the slag pipe is fixed.

[0030] In the above description, threads are respectively arranged in the positioning groove and the insertion hole, and match with the threads on the outside of the positioning bolt.

[0031] In the above description, when the rotating clamping plate is clamped on the support, the cover plate can be combined with the lower port of the slag hopper.

[0032] In the above description, one end of the rotating clamping plate rotates together with the side wall of the slag hopper, and the other end of the rotating clamping plate is placed on the support column.

[0033] When in use, the carbon slag enters from the flash port of the slag discharge pipe and reaches the cover plate through the slag discharge hopper. When it needs to be transported, the carbon slag is withdrawn to the bottom of the slag discharge hopper, and the cover plate is opened by rotating the pallet, so that the carbon slag is dumped from the slag discharge hopper to the carbon slag car, thereby achieving the purpose of transportation.

[0034] In the above description, when the carbon slag transfer is completed, the cover plate is merged with the slag hopper by rotating the pallet to receive the next round of carbon slag.

[0035] In the actual production of electrolytic aluminum, the electrolytic cell undergoes continuous electrochemical reactions, causing the anode carbon blocks to continuously consume slag. Carbon slag is continuously produced and needs to be continuously salvaged by workers. However, traditional carbon slag cleaning requires continuous salvaging and transportation, which increases the workload of workers. The carbon slag cannot be cleaned out in time, causing electrolytic cell diseases. This device can be used to salvage and transport carbon slag at any time at the aluminum outlet, achieving the purpose of timely and effective removal of carbon slag, saving manpower and reducing the possibility of electrolytic cell diseases, which is conducive to the smooth and efficient production of the electrolytic workshop.
