Tank-use adaptive shell-pressing device

Abstract

The invention relates to a tank-use adaptive shell-pressing device comprising a gas cylinder and a hammer. The device is characterized in that a composite valve block in which speed regulation and pressure regulation valve parts are integrated is arranged on the bottom of the gas cylinder; and a gas source enters the cavity of the gas cylinder through the speed regulation and pressure regulation valve parts in the composite valve block, and pushes a piston rod to move up and down. The tank-use adaptive shell-pressing device also comprises a lower-part guiding device used for ensuring the smooth operation of the shell-pressing hammer. The lower-part guiding device which is composed of a slide sleeve and a guiding cylinder is arranged below the gas cylinder. According to the device, traditional impact shell-beating is changed into slow shell-pressing, and shell-pressing is automatically changed into impact shell-beating after meet resistance. Therefore, air consumption is greatly reduced, and energy consumption is saved. The device has the characteristics of smooth operation, long service life, damage resistance, low maintenance volume, and reduced labor intensity.

Description

technical field [0001] The invention relates to equipment for electrolytic aluminum production, in particular to an adaptive shell pressing device, which belongs to the technical field of design and manufacture of nonferrous metallurgical equipment and is suitable for use in electrolytic aluminum plants. Background technique [0002] Electrolytic aluminum plants produce electrolytic cells for primary aluminum. During the production process, the upper surface of the cell forms a hard shell. In the case of continuous consumption of raw materials, new raw materials must be continuously replenished. For this reason, there must be a device to open the shell surface to allow new raw materials to enter the cell. During the chemical reaction, the electrolytic aluminum factories in my country currently use shelling devices in production operations, which consume a large amount of gas, consume a lot of energy, and the pressure cannot be adjusted, causing serious noise. It is stable, sha...

Problems solved by technology

[0002]The electrolytic aluminum plant produces electrolytic cells for primary aluminum. During the production process, the upper surface of the cell forms a hard shell. In the case of continuous consumption of raw materials, new raw materials must be continuously added. For this reason, there must be a device to open the shell surface, so that new raw materials can be replenished into the tank to carry out chemical reactions. At present, all electrolytic aluminum plants in China use shelling devices in production operations, which consume a large amount of gas, serious energy consumption, and the pressure cannot be adjusted. Noise Seriously, there is no guide device in the movement of the hammer head, which makes the movement of the hammer head unstable and shakes from side to side, the parts are easily damaged, and the maintenance work is heavy, which seriously affects the production of the groove. It is urgent to update and improve

This self-adaptive shell pressing device has not been found and used in aluminum factories in my country, and it is the first in China.
