Description

Planer furnace structure in the middle of the overhaul workshop

technical field

The utility model relates to a planer furnace structure in the middle of the overhaul workshop, in particular to a planer furnace structure in the middle of the overhaul workshop in the concentrated overhaul workshop of the electrolytic cells of the electrolytic aluminum factory.

Background technique

In the production process of electrolytic aluminum, the life of the main production equipment - the lining of the electrolytic cell is certain. However, because of the high cost of the electrolyzer and the complicated replacement process, in order to prolong its service life, timely maintenance and repair of the electrolyzer is very necessary. Due to the particularity and complexity of the electrolyzer equipment itself, the process of its maintenance and repair is determined, which is extremely professional and complex. In the centralized overhaul workshop of the electrolyzer, the various stages of the repair process are reasonably divided and layout is necessary.

The planing furnace section of the centralized overhaul workshop of the electrolytic aluminum plant with large-scale and large-scale tanks usually adopts hot planing and dry planing furnace technology. During the process, whether it is planing furnace or waste loading and unloading, a large amount of dust will inevitably be generated. The environmental pollution caused by the planing furnace process is a problem that must be solved in the design process.

Utility model content

In order to solve the above technical problems, the utility model provides a planer furnace structure in the middle of the overhaul workshop, which aims to improve the repair ability, ensure the repair quality, and protect and improve the repair environment at the same time.

In order to achieve the above purpose, the utility model is realized in the following way: the structure of the planer furnace in the middle of the overhaul workshop includes the electrolytic tank and the planer furnace section, and the planer furnace platform is provided in the planer furnace section, and the planer furnace platform is provided with dismantling, transportation and loading and unloading equipment. There is a dust collection cover for the planing furnace process above the furnace platform, which covers the working range of dismantling the transportation and loading and unloading equipment, and a dust collection device for the waste unloading process is installed below the planing furnace platform.

A dodge door is provided on the top of the dust collection hood for the planer furnace process.

The movable door is movable, rolling or rolling.

The lower part of the dust collecting device in the waste unloading process is connected with the unloading hopper.

The dust collecting device and the unloading hopper in the waste unloading process are arranged in the material conveying channel.

A waste transport vehicle is arranged in the material conveying channel.

The two sides of the material conveying passage are provided with retaining walls of the conveying passage.

The planer furnace section is set in the middle of the electrolyzer centralized overhaul workshop.

The utility model has the advantages and effects: when the planing furnace section is set in the middle of the centralized overhaul workshop, the transportation distance of the cathode tank shell of the electrolytic cell is shortened, and a movable door is set on the dust collection cover of the planing furnace process to solve the problem of flexible cathode tank shell of the electrolytic cell. It is convenient to transport in and out, and collect the dust in the planing furnace process and waste loading process to prevent environmental pollution. Under the planer furnace platform, there is a material conveying channel and a waste material unloading process dust collection device to reduce environmental pollution and facilitate transportation during the waste material unloading process.

Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings, but the protection scope of the utility model is not limited by the embodiments.

As shown in Figure 1, Figure 2 and Figure 3, the planer furnace structure in the middle of the overhaul workshop of the utility model includes an electrolytic cell 10 and a planer furnace section 11. Ventilator room 12 is arranged outside, and planer furnace platform 7 is arranged on planer furnace section 11, and planer furnace platform 7 is provided with dismantling transportation and handling equipment 3, removes transportation and handling equipment 3 multipurpose functions of planing furnace, loading and unloading, in The top of the planer furnace platform 7 is provided with a dust collection cover 1 for the planer furnace process. The dust collection cover 1 for the planer furnace process covers the working range of the removal of the transportation and handling equipment 3. The top of the dust collection cover 1 for the planer furnace process is provided with a movable door 2. It is mobile, scrolling or roll-up type, and a waste material unloading process dust collection device 4 is provided under the planer furnace platform 7. The unloading hopper 5 is located in the material delivery channel 8, and the material delivery channel 8 is provided with a waste transport vehicle 6, and the both sides of the material delivery channel 8 are provided with a material delivery channel retaining wall 9; as shown in Figure 3, the material delivery channel 8 is Slope haulage channel.

The working principle of the utility model is as follows: when the transportation and loading and unloading equipment 3 is removed to carry out the planing furnace operation, the air in the dust collecting hood 1 of the planing furnace process causes negative pressure to realize the dust collection purpose of the planing furnace operation and waste loading operation. The waste removed from the cathode shell of the electrolytic cell is loaded into the waste transport vehicle 6 through the unloading hopper 5, and the dust collection device 4 in the waste unloading process collects the dust generated by unloading the waste.
