The invention provides a vertical sealing device for a feed compartment of a carbon extruding machine. A feed hopper is mounted at the upper end of the feed compartment of the carbon extruding machine; the opening of the feed hopper faces upwards; and the feed hopper is used for feeding paste materials into the feed compartment. The sealing device comprises a power unit and a sealing plug, wherein the power unit is mounted above the feed hopper through a bracket; the sealing plug is connected to the lower part of the power unit, and can be inserted into and seal the feed hopper in the vertical direction; and the power unit is used for pushing and pulling the sealing plug in the vertical direction, so as to control the sealing plug to seal or open the opening of the feed hopper. According to the vertical sealing device, the operation process of the system of the extruding machine is simplified; the operation time is shortened; as feeding and reliable sealing can be realized by driving the sealing plug to move up and down with the power unit, the production efficiency of the extruding machine is greatly improved; and being wrapped with heat-proof rubber, the sealing plug has favorable sealing performance, and the sealing performance can be improved automatically with the increase of pressure, so that the qualification rate of products is improved.
Description
technical field [0001] The invention relates to electrode production technology, in particular to a vertical sealing device for a feeding chamber of a carbon extruder that can provide a convenient and stable sealing effect. Background technique [0002] With the development of my country's and the world's steel industry and aluminum industry, the demand for electrodes for steelmaking and electrodes for electrolytic aluminum will increase. In particular, the demand for ultra-high-power electrodes required for smelting special steel will increase. At present, my country's self-made ultra-high-power electrodes are in short supply and need to be imported in large quantities. Therefore, in recent years, the carbon extruders used to produce electrodes will have a broad market at home and abroad. market. [0003] The carbon extruder is the key equipment in the carbon industry. The vertical sealing device of the feeding chamber matched with the carbon extruder has a great influence ...
